This might solve your problem

This happened to me because I was using OpenVPN. I found a way that I don't need to stop using the VPN or manually add a network to the docker-compose file nor run any crazy script.

I switched to WireGuard instead of OpenVPN. More specifically, as I am running the nordvpn solution, I installed WireGuard and used their version of it, NordLynx.

in my case, after encrypting password,I forgot to put settings-security.xml into ~/.m2?

I also faced same problem... I follow the following steps...u can try it 1. Right click on maven project 2. Take cursor in Maven 3. Click on Update Maven project or (alt+F5). it will take some time then most probably problem will solved..

This happens because you're trying to serialize the EF object collection directly. Since department has an association to employee and employee to department, the JSON serializer will loop infinetly reading d.Employee.Departments.Employee.Departments etc...

To fix this right before the serialization create an anonymous type with the props you want

example (psuedo)code:

departments.select(dep => new { 
    dep.Id, 
    Employee = new { 
        dep.Employee.Id, dep.Employee.Name 
    }
});

I was getting the same error with a service access. It was working in browser, but wasnt working when I try to access it in my asp.net/c# application. I changed application pool from appPoolIdentity to NetworkService, and it start working. Seems like a permission issue to me.

This might sound silly, but make sure the "Offline" checkbox in Maven settings is unchecked. I was trying to create a project and got this error until I noticed the checkbox.

Try browse the WCF in IIS see if it's alive and works normally,

In my case it's because the physical path of the WCF is misdirected.

This is solved for me when I update maven and check the option "Force update of Snapshots/Releases" in Eclipse. this clears all errors. So right click on project -> Maven -> update project, then check the above option -> Ok. Hope this helps you.

Upgrade Automapper to version 6.2.2. It helped me

This is a known bug, you can work it around with a hack:

Open up site-packages/requests/packages/urllib3/connectionpool.py (or otherwise just make a local copy of requests inside your own project), and change the block that says:

def connect(self):
    # Add certificate verification
    sock = socket.create_connection((self.host, self.port), self.timeout)

    # Wrap socket using verification with the root certs in
    # trusted_root_certs
    self.sock = ssl_wrap_socket(sock, self.key_file, self.cert_file,
                                cert_reqs=self.cert_reqs,
                                ca_certs=self.ca_certs,
                                server_hostname=self.host,
                                ssl_version=self.ssl_version)

to:

def connect(self):
    # Add certificate verification
    sock = socket.create_connection((self.host, self.port), self.timeout)

    # Wrap socket using verification with the root certs in
    # trusted_root_certs
    self.sock = ssl_wrap_socket(sock, self.key_file, self.cert_file,
                                cert_reqs=self.cert_reqs,
                                ca_certs=self.ca_certs,
                                server_hostname=self.host,
                                ssl_version=ssl.PROTOCOL_TLSv1)

Otherwise, I suppose there's an override somewhere which is less hacky, but I couldn't find one with a few glances.

NOTE: On a sidenote, requests from PIP (1.0.4) on a MacOS just works with the URL you provided.

I face this error on testing WebAPI in Postman tool.

After building the code, If we remove any line (For Example: In my case when I remove one Commented line this error was occur...) in debugging mode then the "Non-static method requires a target" error will occur.

Again, I tried to send the same request. This time code working properly. And I get the response properly in Postman.

I hope it will use to someone...

With the command:

sudo apt-get remove --purge mysql\*

you can delete anything related to packages named mysql. Those commands are only valid on debian / debian-based linux distributions (Ubuntu for example).

You can list all installed mysql packages with the command:

sudo dpkg -l | grep -i mysql

For more cleanup of the package cache, you can use the command:

sudo apt-get clean

Also, remember to use the command:

sudo updatedb

Otherwise the "locate" command will display old data.

To install mysql again, use the following command:

sudo apt-get install libmysqlclient-dev mysql-client

This will install the mysql client, libmysql and its headers files.

To install the mysql server, use the command:

sudo apt-get install mysql-server

This is just additional information for this answer.

If you are using nginx, you would add proxy_set_header X-Real-IP $remote_addr; to the location block for the site. /etc/nginx/sites-available/www.example.com for example. Here is a example server block.

server {
    listen 80;
    listen [::]:80;

    server_name example.com www.example.com;

    location / {
        proxy_set_header  X-Real-IP  $remote_addr;
        proxy_pass http://127.0.1.1:3080;
        proxy_http_version 1.1;
        proxy_set_header Upgrade $http_upgrade;
        proxy_set_header Connection 'upgrade';
        proxy_set_header Host $host;
        proxy_cache_bypass $http_upgrade;
    }
}

After restarting nginx, you will be able to access the ip in your node/express application routes with req.headers['x-real-ip'] || req.connection.remoteAddress;

You can send your data like the "POST" request through the "HEADERS".

Something like this:

$.ajax({
   url: "htttp://api.com/entity/list($body)",
   type: "GET",
   headers: ['id1':1, 'id2':2, 'id3':3],
   data: "",
   contentType: "text/plain",
   dataType: "json",
   success: onSuccess,
   error: onError
});

As Gerben suggested, just change:

order deny,allow
deny from all

to

order allow,deny

And the restrictions will work as you want them to.

Details can be found in Apache's docs.

The proxies' dict syntax is {"protocol":"ip:port", ...}. With it you can specify different (or the same) proxie(s) for requests using http, https, and ftp protocols:

http_proxy  = "http://10.10.1.10:3128"
https_proxy = "https://10.10.1.11:1080"
ftp_proxy   = "ftp://10.10.1.10:3128"

proxyDict = { 
              "http"  : http_proxy, 
              "https" : https_proxy, 
              "ftp"   : ftp_proxy
            }

r = requests.get(url, headers=headers, proxies=proxyDict)

Deduced from the requests documentation:

Parameters:
method – method for the new Request object.
url – URL for the new Request object.
...
proxies – (optional) Dictionary mapping protocol to the URL of the proxy.
...

On linux you can also do this via the HTTP_PROXY, HTTPS_PROXY, and FTP_PROXY environment variables:

export HTTP_PROXY=10.10.1.10:3128
export HTTPS_PROXY=10.10.1.11:1080
export FTP_PROXY=10.10.1.10:3128

On Windows:

set http_proxy=10.10.1.10:3128
set https_proxy=10.10.1.11:1080
set ftp_proxy=10.10.1.10:3128

Thanks, Jay for pointing this out:
The syntax changed with requests 2.0.0.
You'll need to add a schema to the url: https://2.python-requests.org/en/latest/user/advanced/#proxies

Eclipse by default does not know about your external Maven installation and uses the embedded one. Therefore in order for Eclipse to use your global settings you need to set it in menu Settings ? Maven ? Installations.

This is the right answer http://stackoverflow.com/questions/6990767/inject-bean-reference-into-a-quartz-job-in-spring/15211030#15211030. and will work for most of the folks. But if your web.xml does is not aware of all applicationContext.xml files, quartz job will not be able to invoke those beans. I had to do an extra layer to inject additional applicationContext files

public class MYSpringBeanJobFactory extends SpringBeanJobFactory
        implements ApplicationContextAware {

    private transient AutowireCapableBeanFactory beanFactory;

    @Override
    public void setApplicationContext(final ApplicationContext context) {

        try {
                PathMatchingResourcePatternResolver pmrl = new PathMatchingResourcePatternResolver(context.getClassLoader());
                Resource[] resources = new Resource[0];
                GenericApplicationContext createdContext = null ;
                    resources = pmrl.getResources(
                            "classpath*:my-abc-integration-applicationContext.xml"
                    );

                    for (Resource r : resources) {
                        createdContext = new GenericApplicationContext(context);
                        XmlBeanDefinitionReader reader = new XmlBeanDefinitionReader(createdContext);
                        int i = reader.loadBeanDefinitions(r);
                    }

            createdContext.refresh();//important else you will get exceptions.
            beanFactory = createdContext.getAutowireCapableBeanFactory();

        } catch (IOException e) {
            e.printStackTrace();
        }



    }

    @Override
    protected Object createJobInstance(final TriggerFiredBundle bundle)
            throws Exception {
        final Object job = super.createJobInstance(bundle);
        beanFactory.autowireBean(job);
        return job;
    }
}

You can add any number of context files you want your quartz to be aware of.

In my scenario i have make this via below code in nginx vhost configuration

server {
server_name dashboards.etilize.com;

location / {
    proxy_pass http://demo.etilize.com/dashboards/;
    proxy_set_header Host $http_host;
}}

$http_host will set URL in Header same as requested

It's not ideal, but you could disable Jackson's auto-discovery of JSON properties, using @JsonAutoDetect at the class level. This would prevent it from trying to handle the Javassist stuff (and failing).

This means that you then have to annotate each getter manually (with @JsonProperty), but that's not necessarily a bad thing, since it keeps things explicit.

First, this is not an error. The 3xx denotes a redirection. The real errors are 4xx (client error) and 5xx (server error).

If a client gets a 304 Not Modified, then it's the client's responsibility to display the resouce in question from its own cache. In general, the proxy shouldn't worry about this. It's just the messenger.

I found a solution to deproxy a class using standard Java and JPA API. Tested with hibernate, but does not require hibernate as a dependency and should work with all JPA providers.

Onle one requirement - its necessary to modify parent class (Address) and add a simple helper method.

General idea: add helper method to parent class which returns itself. when method called on proxy, it will forward the call to real instance and return this real instance.

Implementation is a little bit more complex, as hibernate recognizes that proxied class returns itself and still returns proxy instead of real instance. Workaround is to wrap returned instance into a simple wrapper class, which has different class type than the real instance.

In code:

class Address {
   public AddressWrapper getWrappedSelf() {
       return new AddressWrapper(this);
   }
...
}

class AddressWrapper {
    private Address wrappedAddress;
...
}

To cast Address proxy to real subclass, use following:

Address address = dao.getSomeAddress(...);
Address deproxiedAddress = address.getWrappedSelf().getWrappedAddress();
if (deproxiedAddress instanceof WorkAddress) {
WorkAddress workAddress = (WorkAddress)deproxiedAddress;
}

I came up with this function that does not simply return the IP address but an array with IP information.

// Example usage:
$info = ip_info();
if ( $info->proxy ) {
    echo 'Your IP is ' . $info->ip;
} else {
    echo 'Your IP is ' . $info->ip . ' and your proxy is ' . $info->proxy_ip;
}

Here's the function:

/**
 * Retrieves the best guess of the client's actual IP address.
 * Takes into account numerous HTTP proxy headers due to variations
 * in how different ISPs handle IP addresses in headers between hops.
 *
 * @since 1.1.3
 *
 * @return object {
 *         IP Address details
 *
 *         string $ip The users IP address (might be spoofed, if $proxy is true)
 *         bool $proxy True, if a proxy was detected
 *         string $proxy_id The proxy-server IP address
 * }
 */
function ip_info() {
    $result = (object) array(
        'ip' => $_SERVER['REMOTE_ADDR'],
        'proxy' => false,
        'proxy_ip' => '',
    );

    /*
     * This code tries to bypass a proxy and get the actual IP address of
     * the visitor behind the proxy.
     * Warning: These values might be spoofed!
     */
    $ip_fields = array(
        'HTTP_CLIENT_IP',
        'HTTP_X_FORWARDED_FOR',
        'HTTP_X_FORWARDED',
        'HTTP_X_CLUSTER_CLIENT_IP',
        'HTTP_FORWARDED_FOR',
        'HTTP_FORWARDED',
        'REMOTE_ADDR',
    );
    foreach ( $ip_fields as $key ) {
        if ( array_key_exists( $key, $_SERVER ) === true ) {
            foreach ( explode( ',', $_SERVER[$key] ) as $ip ) {
                $ip = trim( $ip );

                if ( filter_var( $ip, FILTER_VALIDATE_IP, FILTER_FLAG_NO_PRIV_RANGE | FILTER_FLAG_NO_RES_RANGE ) !== false ) {
                    $forwarded = $ip;
                    break 2;
                }
            }
        }
    }

    // If we found a different IP address then REMOTE_ADDR then it's a proxy!
    if ( $forwarded != $result->ip ) {
        $result->proxy = true;
        $result->proxy_ip = $result->ip;
        $result->ip = $forwarded;
    }

    return $result;
}

Have you read this post?

Maybe it explains, why it was kinda difficult the last days.

You can set proxies using environment variables.

import os
os.environ['http_proxy'] = '127.0.0.1'
os.environ['https_proxy'] = '127.0.0.1'

urllib2 will add proxy handlers automatically this way. You need to set proxies for different protocols separately otherwise they will fail (in terms of not going through proxy), see below.

For example:

proxy = urllib2.ProxyHandler({'http': '127.0.0.1'})
opener = urllib2.build_opener(proxy)
urllib2.install_opener(opener)
urllib2.urlopen('http://www.google.com')
# next line will fail (will not go through the proxy) (https)
urllib2.urlopen('https://www.google.com')

Instead

proxy = urllib2.ProxyHandler({
    'http': '127.0.0.1',
    'https': '127.0.0.1'
})
opener = urllib2.build_opener(proxy)
urllib2.install_opener(opener)
# this way both http and https requests go through the proxy
urllib2.urlopen('http://www.google.com')
urllib2.urlopen('https://www.google.com')

As a visual person, I like to weigh in with a sequence diagram of the proxy pattern. If you don't know how to read the arrows, I read the first one like this: Client executes Proxy.method().

1. The client calls a method on the target from his perspective, and is silently intercepted by the proxy
2. If a before aspect is defined, the proxy will execute it
3. Then, the actual method (target) is executed
4. After-returning and after-throwing are optional aspects that are executed after the method returns and/or if the method throws an exception
5. After that, the proxy executes the after aspect (if defined)
6. Finally the proxy returns to the calling client

In our case the problem was that we change the default root namespace name.

This is the Project Configuration screen

We finally decided to back to the original name and the problem was solved.

The problem actually was the dots in the Root namespace. With two dots (Name.Child.Child) it doesnt work. But with one (Name.ChidChild) works.

Is there really a difference between:

class User implements IUser

and

class UserImpl implements User

if all we're talking about is naming conventions?

Personally I prefer NOT preceding the interface with I as I want to be coding to the interface and I consider that to be more important in terms of the naming convention. If you call the interface IUser then every consumer of that class needs to know its an IUser. If you call the class UserImpl then only the class and your DI container know about the Impl part and the consumers just know they're working with a User.

Then again, the times I've been forced to use Impl because a better name doesn't present itself have been few and far between because the implementation gets named according to the implementation because that's where it's important, e.g.

class DbBasedAccountDAO implements AccountDAO
class InMemoryAccountDAO implements AccountDAO

You should avoid putting client proxies in using blocks.

A key compatibility issue is support for persistent connections. I recently worked on a server that "supported" HTTP/1.1, yet failed to close the connection when a client sent an HTTP/1.0 request. When writing a server that supports HTTP/1.1, be sure it also works well with HTTP/1.0-only clients.

You can use the CONCAT with CURDATE() to the entire time of the day and then filter by using the BETWEEN in WHERE condition:

SELECT users.id, DATE_FORMAT(users.signup_date, '%Y-%m-%d') 
FROM users 
WHERE (users.signup_date BETWEEN CONCAT(CURDATE(), ' 00:00:00') AND CONCAT(CURDATE(), ' 23:59:59'))

They are exactly the same. When you use it be consistent. Use one of them in your database

If is a package then you can get the source for that with:

    select text from all_source where name = 'PADCAMPAIGN' 
    and type = 'PACKAGE BODY'
    order by line;

Oracle doesn't store the source for a sub-program separately, so you need to look through the package source for it.

Note: I've assumed you didn't use double-quotes when creating that package, but if you did , then use

    select text from all_source where name = 'pAdCampaign' 
    and type = 'PACKAGE BODY'
    order by line;

It's very easy with fs.

var fs = require('fs');
try{
 var sourceUrls = "/sampleFolder/sampleFile.txt";
 fs.unlinkSync(sourceUrls);
}catch(err){
 console.log(err);
}

smiley favicon to prevent error:

 //const fs = require('fs'); 
 //const favicon = fs.readFileSync(__dirname+'/public/favicon.ico'); // read file
 const favicon = new Buffer.from('AAABAAEAEBAQAAAAAAAoAQAAFgAAACgAAAAQAAAAIAAAAAEABAAAAAAAgAAAAAAAAAAAAAAAEAAAAAAAAAAAAAAA/4QAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAEREQAAAAAAEAAAEAAAAAEAAAABAAAAEAAAAAAQAAAQAAAAABAAAAAAAAAAAAAAAAAAAAAAAAAAEAABAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAD//wAA//8AAP//AAD8HwAA++8AAPf3AADv+wAA7/sAAP//AAD//wAA+98AAP//AAD//wAA//8AAP//AAD//wAA', 'base64'); 
 app.get("/favicon.ico", function(req, res) {
  res.statusCode = 200;
  res.setHeader('Content-Length', favicon.length);
  res.setHeader('Content-Type', 'image/x-icon');
  res.setHeader("Cache-Control", "public, max-age=2592000");                // expiers after a month
  res.setHeader("Expires", new Date(Date.now() + 2592000000).toUTCString());
  res.end(favicon);
 });

to change icon in code above

make an icon maybe here: http://www.favicon.cc/ or here :http://favicon-generator.org

convert it to base64 maybe here: http://base64converter.com/

then replace the icon base 64 value

general information how to create a personalized fav icon

icons are made using photoshop or inkscape, maybe inkscape then photoshop for vibrance and color correction (in image->adjustments menu).

for quick icon goto http://www.clker.com/ and pick some Vector Clip Arts, and download as svg. then bring it to inkscape (https://inkscape.org/) and change colors or delete parts, maybe add something from another vector clipart image, then to export select the parts to export and click file>export, pick size like 16x16 for favicon or 32x32. for further edit 128x128 or 256x256. ico package can have several icon sizes inside. it can have along with 16x16 pixel favicon a high quality icons for link for the website.

then maybe enhance the image in photoshop. like vibrance, bevel effect, round mask, anything.

then upload this image to one of the websites that generate favicons. there are also programs for windows for editing icons like https://sourceforge.net/projects/variicons/ .

to add the favicon to website. just put the favicon.ico as a file in the root folder of the domain. for example in node.js in public folder that contains the static files. it doesn't have to be anything special like code above just a simple file.

here is something i did.

function foreach(o, f) {
 for(var i = 0; i < o.length; i++) { // simple for loop
  f(o[i], i); // execute a function and make the obj, objIndex available
 }
}

this is how you would use it
this will work on arrays and objects( such as a list of HTML elements )

foreach(o, function(obj, i) { // for each obj in o
  alert(obj); // obj
  alert(i); // obj index
  /*
    say if you were dealing with an html element may be you have a collection of divs
  */
  if(typeof obj == 'object') { 
   obj.style.marginLeft = '20px';
  }
});

I just made this so I'm open to suggestions :)

useState() is a React hook. Hooks make possible to use state and mutability inside function components.

While you can't use hooks inside classes you can wrap your class component with a function one and use hooks from it. This is a great tool for migrating components from class to function form. Here is a complete example:

For this example I will use a counter component. This is it:

class Hello extends React.Component {_x000D_
  constructor(props) {_x000D_
    super(props);_x000D_
    this.state = { count: props.count };_x000D_
  }_x000D_
  _x000D_
  inc() {_x000D_
    this.setState(prev => ({count: prev.count+1}));_x000D_
  }_x000D_
  _x000D_
  render() {_x000D_
    return <button onClick={() => this.inc()}>{this.state.count}</button>_x000D_
  }_x000D_
}_x000D_
_x000D_
ReactDOM.render(<Hello count={0}/>, document.getElementById('root'))

<script src="https://cdnjs.cloudflare.com/ajax/libs/react/16.6.3/umd/react.production.min.js"></script>_x000D_
<script src="https://cdnjs.cloudflare.com/ajax/libs/react-dom/16.6.3/umd/react-dom.production.min.js"></script>_x000D_
<div id='root'></div>

It is a simple class component with a count state, and state update is done by methods. This is very common pattern in class components. The first thing is to wrap it with a function component with just the same name, that delegate all its properties to the wrapped component. Also you need to render the wrapped component in the function return. Here it is:

function Hello(props) {_x000D_
  class Hello extends React.Component {_x000D_
    constructor(props) {_x000D_
      super(props);_x000D_
      this.state = { count: props.count };_x000D_
    }_x000D_
_x000D_
    inc() {_x000D_
      this.setState(prev => ({count: prev.count+1}));_x000D_
    }_x000D_
_x000D_
    render() {_x000D_
      return <button onClick={() => this.inc()}>{this.state.count}</button>_x000D_

<div id='root'></div>

This is exactly the same component, with the same behavior, same name and same properties. Now lets lift the counting state to the function component. This is how it goes:

function Hello(props) {_x000D_
  const [count, setCount] = React.useState(0);_x000D_
  class Hello extends React.Component {_x000D_
    constructor(props) {_x000D_
      super(props);_x000D_
      this.state = { count: props.count };_x000D_
    }_x000D_
_x000D_
    inc() {_x000D_
      this.setState(prev => ({count: prev.count+1}));_x000D_
    }_x000D_
_x000D_
    render() {_x000D_
      return <button onClick={() => setCount(count+1)}>{count}</button>_x000D_
    }_x000D_
  }_x000D_
  return <Hello {...props}/>_x000D_
}_x000D_
_x000D_
ReactDOM.render(<Hello count={0}/>, document.getElementById('root'))

<script src="https://cdnjs.cloudflare.com/ajax/libs/react/16.8.6/umd/react.production.min.js" integrity="sha256-3vo65ZXn5pfsCfGM5H55X+SmwJHBlyNHPwRmWAPgJnM=" crossorigin="anonymous"></script>_x000D_

<div id='root'></div>

Note that the method inc is still there, it wont hurt anybody, in fact is dead code. This is the idea, just keep lifting state up. Once you finished you can remove the class component:

function Hello(props) {_x000D_
  const [count, setCount] = React.useState(0);_x000D_
_x000D_
  return <button onClick={() => setCount(count+1)}>{count}</button>;_x000D_
}_x000D_
_x000D_
ReactDOM.render(<Hello count={0}/>, document.getElementById('root'))

<script src="https://cdnjs.cloudflare.com/ajax/libs/react/16.8.6/umd/react.production.min.js" integrity="sha256-3vo65ZXn5pfsCfGM5H55X+SmwJHBlyNHPwRmWAPgJnM=" crossorigin="anonymous"></script>_x000D_

_x000D_
<div id='root'></div>

While this makes possible to use hooks inside class components, I would not recommend you to do so except if you migrating like I did in this example. Mixing function and class components will make state management a mess. I hope this helps

You need to set the width of the container (auto won't work):

#container {
    width: 640px; /* Can be in percentage also. */
    height: auto;
    margin: 0 auto;
    padding: 10px;
    position: relative;
}

The CSS reference by MDN explains it all.

The key is "operating system error 5". Microsoft helpfully list the various error codes and values on their site

It sounds like you have a problem with your dsn or odbc data source.

Try bypassing the dsn first and connect using:

TDSVER=8.0 tsql -S *serverIPAddress* -U *username* -P *password*

If that works, you know its an issue with your dsn or with freetds using your dsn. Also, it is possible that your tds version is not compatible with your server. You might want to try other TDSVER settings (5.0, 7.0, 7.1).

I was looking similar but I wanted the difference in either list (uncommon elements between the 2 lists).

Let say I have:

List<String> oldKeys = Arrays.asList("key0","key1","key2","key5");
List<String> newKeys = Arrays.asList("key0","key2","key5", "key6");

And I wanted to know which key has been added and which key is removed i.e I wanted to get (key1, key6)

Using org.apache.commons.collections.CollectionUtils

List<String> list = new ArrayList<>(CollectionUtils.disjunction(newKeys, oldKeys));

Result

["key1", "key6"]

Open XAMPP look below the X to close the program there is a Config option click it then click service and port settings then under Apache change your main port to whatever you changed it to in the config file then click save and your good to go.

The previous answers did not work for me, but this did:

If you think of the body of a loop as a subroutine, continue is sort of like return. The same keyword exists in C, and serves the same purpose. Here's a contrived example:

for(int i=0; i < 10; ++i) {
  if (i % 2 == 0) {
    continue;
  }
  System.out.println(i);
}

This will print out only the odd numbers.

What's new in .NET Framework 4 Client Profile RTM explains many of the differences:

When to use NET4 Client Profile and when to use NET4 Full Framework?
NET4 Client Profile:
Always target NET4 Client Profile for all your client desktop applications (including Windows Forms and WPF apps).

NET4 Full framework:
Target NET4 Full only if the features or assemblies that your app need are not included in the Client Profile. This includes:

• If you are building Server apps. Such as:
  o ASP.Net apps
  o Server-side ASMX based web services
• If you use legacy client scenarios. Such as:
  o Use System.Data.OracleClient.dll which is deprecated in NET4 and not included in the Client Profile.
  o Use legacy Windows Workflow Foundation 3.0 or 3.5 (WF3.0 , WF3.5)
• If you targeting developer scenarios and need tool such as MSBuild or need access to design assemblies such as System.Design.dll

However, as stated on MSDN, this is not relevant for >=4.5:

Starting with the .NET Framework 4.5, the Client Profile has been discontinued and only the full redistributable package is available. Optimizations provided by the .NET Framework 4.5, such as smaller download size and faster deployment, have eliminated the need for a separate deployment package. The single redistributable streamlines the installation process and simplifies your app's deployment options.

    boolean x;
    for (x = false, 
        map.put("One", new Integer(1)), 
        map.put("Two", new Integer(2)),      
        map.put("Three", new Integer(3)); x;);

Ignoring the declaration of x (which is necessary to avoid an "unreachable statement" diagnostic), technically it's only one statement.

<html>
<head>
<script type="text/javascript">
function test(){
var map= {'m1': 12,'m2': 13,'m3': 14,'m4': 15}

}
</script>
</head>

MVC Razor provides one elegant Html Helper called RadioButton with two parameters (this is general, But we can overload it uptil five parameters) i.e. one with the group name and other being the value

<div class="col-md-10">
    Male:   @Html.RadioButton("Gender", "Male")
    Female: @Html.RadioButton("Gender", "Female")
</div>                         

$('.clickable').hover(function(){
      $('.selector').stop(true,true).fadeTo( 400 , 0.0, function() {
        $('.selector').css('background-image',"url('assets/img/pic2.jpg')");
        });
    $('.selector').fadeTo( 400 , 1);
},
function(){
      $('.selector').stop(false,true).fadeTo( 400 , 0.0, function() {
        $('.selector').css('background-image',"url('assets/img/pic.jpg')");
        });
    $('.selector').fadeTo( 400 , 1);
}

);

You don't need to escape it inside. You can use the | character to delimit searches.

"\"foo\"\'bar\'".replace(/("|')/g, "")

if sum of column is 0 then display empty

select if(sum(column)>0,sum(column),'')
from table 

Use DATE(NOW()) to compare dates

DATE(NOW()) will give you the date part of current date and DATE(duedate) will give you the date part of the due date. then you can easily compare the dates

So you can compare it like

DATE(NOW()) = DATE(duedate)

OR

DATE(duedate) = CURDATE() 

See here

It's best practice only to escape the quotes when you need to - if you can get away without escaping it, then do!

The only times you should need to escape are when trying to put " inside a string, or ' in a character:

String quotes = "He said \"Hello, World!\"";
char quote = '\'';

You can use Manifold's @JailBreak for direct, type-safe Java reflection:

@JailBreak Foo foo = new Foo();
foo.stuffIWant = "123;

public class Foo {
    private String stuffIWant;
}

@JailBreak unlocks the foo local variable in the compiler for direct access to all the members in Foo's hierarchy.

Similarly you can use the jailbreak() extension method for one-off use:

foo.jailbreak().stuffIWant = "123";

Through the jailbreak() method you can access any member in Foo's hierarchy.

In both cases the compiler resolves the field access for you type-safely, as if a public field, while Manifold generates efficient reflection code for you under the hood.

Discover more about Manifold.

You could use something like:

import datetime
days_in_month = 365.25 / 12  # represent the average of days in a month by year
month_diff = lambda end_date, start_date, precision=0: round((end_date - start_date).days / days_in_month, precision)
start_date = datetime.date(1978, 12, 15)
end_date = datetime.date(2012, 7, 9)
month_diff(end_date, start_date)  # should show 403.0 months

You might have some luck calling the Win32 API's MessageBoxA, although whether Win16 supports that particular method is for someone else to answer.

The Swift version from String to Data and back to String:

Xcode 10.1 • Swift 4.2.1

extension Data {
    var string: String? {
        return String(data: self, encoding: .utf8)
    }
}

extension StringProtocol {
    var data: Data {
        return Data(utf8)
    }
}

extension String {
    var base64Decoded: Data? {
        return Data(base64Encoded: self)
    }
}

Playground

let string = "Hello World"                                  // "Hello World"
let stringData = string.data                                // 11 bytes
let base64EncodedString = stringData.base64EncodedString()  // "SGVsbG8gV29ybGQ="
let stringFromData = stringData.string                      // "Hello World"

let base64String = "SGVsbG8gV29ybGQ="
if let data = base64String.base64Decoded {
    print(data)                                    //  11 bytes
    print(data.base64EncodedString())              // "SGVsbG8gV29ybGQ="
    print(data.string ?? "nil")                    // "Hello World"
}

let stringWithAccent = "Olá Mundo"                          // "Olá Mundo"
print(stringWithAccent.count)                               // "9"
let stringWithAccentData = stringWithAccent.data            // "10 bytes" note: an extra byte for the acute accent
let stringWithAccentFromData = stringWithAccentData.string  // "Olá Mundo\n"

Another option in case you don't wanna use a plugin:

Ctrl+` or

View -> Show Console

type on the console the following command:

view.encoding()

In case you want to something more intrusive, there's a option to create an shortcut that executes the following command:

sublime.message_dialog(view.encoding())

you need to wrap your text inside div and float it left while wrapper div should have height, and I've also added line height for vertical alignment

   <div style="float:left;line-height:30px;">Contact Details</div>

    <button type="button" class="edit_button" style="float: right;">My Button</button>

</div>

• First, Download MySQL connector jar file, This is the latest jar file as of today [mysql-connector-java-8.0.21].

• Add the Jar file to your workspace [build path].

• Then Create a new Connection object from the DriverManager class, so you could use this Connection object to execute queries.

• Define the database name, userName, and Password for your connection.

• Use the resultSet to get the data based one the column name from your database table.

Sample code is here:

public class JdbcMySQLExample{

public static void main(String[] args) {

    String url = "jdbc:mysql://localhost:3306/YOUR_DB_NAME?useSSL=false";
    String user = "root";
    String password = "root";
    
    String query = "SELECT * from YOUR_TABLE_NAME";

    try (Connection con = DriverManager.getConnection(url, user, password);
        Statement st = con.createStatement();
        ResultSet rs = st.executeQuery(query)) {

        if (rs.next()) {

Sorry for reactivating this question, but I didn't find the right answer here.

In formatting numbers you can use 0 as a mandatory place and # as an optional place.

So:

// just two decimal places
String.Format("{0:0.##}", 123.4567);      // "123.46"
String.Format("{0:0.##}", 123.4);         // "123.4"
String.Format("{0:0.##}", 123.0);         // "123"

You can also combine 0 with #.

String.Format("{0:0.0#}", 123.4567)       // "123.46"
String.Format("{0:0.0#}", 123.4)          // "123.4"
String.Format("{0:0.0#}", 123.0)          // "123.0"

For this formating method is always used CurrentCulture. For some Cultures . will be changed to ,.

Answer to original question:

The simpliest solution comes from @Andrew (here). So I personally would use something like this:

var number = 123.46;
String.Format(number % 1 == 0 ? "{0:0}" : "{0:0.00}", number)

If you can use JavaScript, the following might be the most portable option today (tested Firefox 31, Chrome 36):

• a div with contenteditable="true"
• the styles suggested by Partly
• JavaScript form submission on button click: How to submit a form using javascript?

http://jsfiddle.net/cirosantilli/eaxgesoq/

<style>
  div#editor {
    white-space: pre;
    word-wrap: normal;
    overflow-x: scroll;
  }
<style>
<div contenteditable="true"></div>

There seems to be no standard, portable CSS solution:

• wrap attribute is not standard

• white-space: pre; does not work for Firefox 31 for textarea. Fiddle, open feature request.

Also, if you can use Javascript, you might as well use the ACE editor:

http://jsfiddle.net/cirosantilli/bL9vr8o8/

<script src="http://cdnjs.cloudflare.com/ajax/libs/ace/1.1.3/ace.js"></script>
<div id="editor">content</div>
<script>
  var editor = ace.edit('editor')
  editor.renderer.setShowGutter(false)
</script>

Probably works with ACE because it does not use a textarea either which is underspecified / incoherently implemented, but not sure if it is uses contenteditable.

Try this:

Display display   = getWindowManager().getDefaultDisplay();
Point displaySize = new Point();
display.getSize(displaySize);
int width  = displaySize.x;
int height = displaySize.y;

Take a look at the ListBox control to allow multi-select.

<asp:ListBox runat="server" ID="lblMultiSelect" SelectionMode="multiple">
            <asp:ListItem Text="opt1" Value="opt1" />
            <asp:ListItem Text="opt2" Value="opt2" />
            <asp:ListItem Text="opt3" Value="opt3" />
</asp:ListBox> 

in the code behind

foreach(ListItem listItem in lblMultiSelect.Items)
    {
       if (listItem.Selected)
       {
          var val = listItem.Value;
          var txt = listItem.Text; 
       }
    }

One caveat on using window.open() is that if the url that you pass to it doesn't have http:// or https:// in front of it, angular treats it as a route.

To get around this, test if the url starts with http:// or https:// and append it if it doesn't.

let url: string = '';
if (!/^http[s]?:\/\//.test(this.urlToOpen)) {
    url += 'http://';
}

url += this.urlToOpen;
window.open(url, '_blank');

There are common use-cases dual y axes, e.g., the climatograph showing monthly temperature and precipitation. Here is a simple solution, generalized from Megatron's solution by allowing you to set the lower limit of the variables to something else than zero:

Example data:

climate <- tibble(
  Month = 1:12,
  Temp = c(-4,-4,0,5,11,15,16,15,11,6,1,-3),
  Precip = c(49,36,47,41,53,65,81,89,90,84,73,55)
  )

Set the following two values to values close to the limits of the data (you can play around with these to adjust the positions of the graphs; the axes will still be correct):

ylim.prim <- c(0, 180)   # in this example, precipitation
ylim.sec <- c(-4, 18)    # in this example, temperature

The following makes the necessary calculations based on these limits, and makes the plot itself:

b <- diff(ylim.prim)/diff(ylim.sec)
a <- ylim.prim[1] - b*ylim.sec[1]) # there was a bug here

ggplot(climate, aes(Month, Precip)) +
  geom_col() +
  geom_line(aes(y = a + Temp*b), color = "red") +
  scale_y_continuous("Precipitation", sec.axis = sec_axis(~ (. - a)/b, name = "Temperature")) +
  scale_x_continuous("Month", breaks = 1:12) +
  ggtitle("Climatogram for Oslo (1961-1990)")  

If you want to make sure that the red line corresponds to the right-hand y axis, you can add a theme sentence to the code:

ggplot(climate, aes(Month, Precip)) +
  geom_col() +
  geom_line(aes(y = a + Temp*b), color = "red") +
  scale_y_continuous("Precipitation", sec.axis = sec_axis(~ (. - a)/b, name = "Temperature")) +
  scale_x_continuous("Month", breaks = 1:12) +
  theme(axis.line.y.right = element_line(color = "red"), 
        axis.ticks.y.right = element_line(color = "red"),
        axis.text.y.right = element_text(color = "red"), 
        axis.title.y.right = element_text(color = "red")
        ) +
  ggtitle("Climatogram for Oslo (1961-1990)")

which colors the right-hand axis:

I was able to get this working with CSS only.

The trick is to use display: flex; and flex-direction: column-reverse;

The browser treats the bottom like its the top. Assuming the browsers you're targeting support flex-box, the only caveat is that the markup has to be in reverse order.

Here is a working example. https://codepen.io/jimbol/pen/YVJzBg

You need to modify your function as:

function toggleTable()
{
   if (document.getElementById("loginTable").style.display == "table" ) {
       document.getElementById("loginTable").style.display="none";

   } else {
      document.getElementById("loginTable").style.display="table";

}

currently it is checking based on the boolean parameter, you don't have to pass the parameter with your function.

You need to modify your anchor tag as:

<a id="loginLink" onclick="toggleTable();" href="#">Login</a>

You have 3 options to make your way:
1. Define a date value like '1970-01-01'
2. Select NULL from the dropdown to keep it blank.
3. Select CURRENT_TIMESTAMP to set current datetime as default value.

Just start emulator by command line as follow:

emulator -avd <your avd name> -partition-size 1024 -wipe-data

I love the Try pattern. It's a tidy pattern.

if (double.TryParse(name, out var result))
{
    // handle success
}
else
{
    // handle error
}

But, it's challenging with async. That doesn't mean we don't have real options. Here are the three core approaches you can consider for async methods in a quasi-version of the Try pattern.

Approach 1 - output a structure

This looks most like a sync Try method only returning a tuple instead of a bool with an out parameter, which we all know is not permitted in C#.

var result = await DoAsync(name);
if (result.Success)
{
    // handle success
}
else
{
    // handle error
}

With a method that returns true of false and never throws an exception.

Remember, throwing an exception in a Try method breaks the whole purpose of the pattern.

async Task<(bool Success, StorageFile File, Exception exception)> DoAsync(string fileName)
{
    try
    {
        var folder = ApplicationData.Current.LocalCacheFolder;
        return (true, await folder.GetFileAsync(fileName), null);
    }
    catch (Exception exception)
    {
        return (false, null, exception);
    }
}

Approach 2 - pass in callback methods

We can use anonymous methods to set external variables. It's clever syntax, though slightly complicated. In small doses, it's fine.

var file = default(StorageFile);
var exception = default(Exception);
if (await DoAsync(name, x => file = x, x => exception = x))
{
    // handle success
}
else
{
    // handle failure
}

The method obeys the basics of the Try pattern but sets out parameters to passed in callback methods. It's done like this.

async Task<bool> DoAsync(string fileName, Action<StorageFile> file, Action<Exception> error)
{
    try
    {
        var folder = ApplicationData.Current.LocalCacheFolder;
        file?.Invoke(await folder.GetFileAsync(fileName));
        return true;
    }
    catch (Exception exception)
    {
        error?.Invoke(exception);
        return false;
    }
}

There's a question in my mind about performance here. But, the C# compiler is so freaking smart, that I think you're safe choosing this option, almost for sure.

Approach 3 - use ContinueWith

What if you just use the TPL as designed? No tuples. The idea here is that we use exceptions to redirect ContinueWith to two different paths.

await DoAsync(name).ContinueWith(task =>
{
    if (task.Exception != null)
    {
        // handle fail
    }
    if (task.Result is StorageFile sf)
    {
        // handle success
    }
});

With a method that throws an exception when there is any kind of failure. That's different than returning a boolean. It's a way to communicate with the TPL.

async Task<StorageFile> DoAsync(string fileName)
{
    var folder = ApplicationData.Current.LocalCacheFolder;
    return await folder.GetFileAsync(fileName);
}

In the code above, if the file is not found, an exception is thrown. This will invoke the failure ContinueWith that will handle Task.Exception in its logic block. Neat, huh?

Listen, there's a reason we love the Try pattern. It's fundamentally so neat and readable and, as a result, maintainable. As you choose your approach, watchdog for readability. Remember the next developer who in 6 months and doesn't have you to answer clarifying questions. Your code can be the only documentation a developer will ever have.

Best of luck.

I have implemented the Samsung File Selector Dialog, it provides the ability to open, save file, file extension filter, and create new directory in the same dialog I think it worth trying Here is the Link you have to log in to Samsung developer site to view the solution

You really shouldn't be doing this, the correct use of timeout is the right tool for the OP's problem and any other occasion where you just want to run something after a period of time. Joseph Silber has demonstrated that well in his answer. However, if in some non-production case you really want to hang the main thread for a period of time, this will do it.

function wait(ms){
   var start = new Date().getTime();
   var end = start;
   while(end < start + ms) {
     end = new Date().getTime();
  }
}

With execution in the form:

console.log('before');
wait(7000);  //7 seconds in milliseconds
console.log('after');

I've arrived here because I was building a simple test case for sequencing a mix of asynchronous operations around long-running blocking operations (i.e. expensive DOM manipulation) and this is my simulated blocking operation. It suits that job fine, so I thought I post it for anyone else who arrives here with a similar use case. Even so, it's creating a Date() object in a while loop, which might very overwhelm the GC if it runs long enough. But I can't emphasize enough, this is only suitable for testing, for building any actual functionality you should refer to Joseph Silber's answer.

To anyone who came across this question who are using SQL Server Database and still having an exception thrown even after adding the following annotation on the int primary key

[Key]
[DatabaseGenerated(DatabaseGeneratedOption.Identity)]
public int Id { get; set; }

Please check your SQL, make sure your the primary key has 'IDENTITY(startValue, increment)' next to it,

CREATE TABLE [dbo].[User]
(
    [Id] INT IDENTITY(1,1) NOT NULL PRIMARY KEY
)

This will make the database increments the id every time a new row is added, with a starting value of 1 and increments of 1.

I accidentally overlooked that in my SQL which cost me an hour of my life, so hopefully this helps someone!!!

import static net.minidev.json.JSONValue.isValidJson;

and then call this function passing in your JSON String :)

To fetch only one distinct record from duplicate column of two rows you can use "rowid" column which is maintained by oracle itself as Primary key,so first try

"select rowid,RequestID,CreatedDate,HistoryStatus  from temptable;"

and then you can fetch second row only by it's value of 'rowid' column by using in SELECT statement.

I stumbled across this question while hitting this road block myself. I ended up writing a piece of code real quick to handle this ReDim Preserve on a new sized array (first or last dimension). Maybe it will help others who face the same issue.

So for the usage, lets say you have your array originally set as MyArray(3,5), and you want to make the dimensions (first too!) larger, lets just say to MyArray(10,20). You would be used to doing something like this right?

 ReDim Preserve MyArray(10,20) '<-- Returns Error

But unfortunately that returns an error because you tried to change the size of the first dimension. So with my function, you would just do something like this instead:

 MyArray = ReDimPreserve(MyArray,10,20)

Now the array is larger, and the data is preserved. Your ReDim Preserve for a Multi-Dimension array is complete. :)

And last but not least, the miraculous function: ReDimPreserve()

'redim preserve both dimensions for a multidimension array *ONLY
Public Function ReDimPreserve(aArrayToPreserve,nNewFirstUBound,nNewLastUBound)
    ReDimPreserve = False
    'check if its in array first
    If IsArray(aArrayToPreserve) Then       
        'create new array
        ReDim aPreservedArray(nNewFirstUBound,nNewLastUBound)
        'get old lBound/uBound
        nOldFirstUBound = uBound(aArrayToPreserve,1)
        nOldLastUBound = uBound(aArrayToPreserve,2)         
        'loop through first
        For nFirst = lBound(aArrayToPreserve,1) to nNewFirstUBound
            For nLast = lBound(aArrayToPreserve,2) to nNewLastUBound
                'if its in range, then append to new array the same way
                If nOldFirstUBound >= nFirst And nOldLastUBound >= nLast Then
                    aPreservedArray(nFirst,nLast) = aArrayToPreserve(nFirst,nLast)
                End If
            Next
        Next            
        'return the array redimmed
        If IsArray(aPreservedArray) Then ReDimPreserve = aPreservedArray
    End If
End Function

I wrote this in like 20 minutes, so there's no guarantees. But if you would like to use or extend it, feel free. I would've thought that someone would've had some code like this up here already, well apparently not. So here ya go fellow gearheads.

If I understand your questions correctly, all you need to do is add the .Where(m => m.r.u.UserId == 1):

    var UserInRole = db.UserProfiles.
        Join(db.UsersInRoles, u => u.UserId, uir => uir.UserId,
        (u, uir) => new { u, uir }).
        Join(db.Roles, r => r.uir.RoleId, ro => ro.RoleId, (r, ro) => new { r, ro })
        .Where(m => m.r.u.UserId == 1)
        .Select (m => new AddUserToRole
        {
            UserName = m.r.u.UserName,
            RoleName = m.ro.RoleName
        });

Hope that helps.

here is an example, where the length of the array is changed during execution of the loop

import java.util.ArrayList;
public class VariableArrayLengthLoop {

public static void main(String[] args) {

    //create new ArrayList
    ArrayList<String> aListFruits = new ArrayList<String>();

    //add objects to ArrayList
    aListFruits.add("Apple");
    aListFruits.add("Banana");
    aListFruits.add("Orange");
    aListFruits.add("Strawberry");

    //iterate ArrayList using for loop
    for(int i = 0; i < aListFruits.size(); i++){

        System.out.println( aListFruits.get(i) + " i = "+i );
         if ( i == 2 ) {
                aListFruits.add("Pineapple");  
                System.out.println( "added now a Fruit to the List "); 
                }
        }
    }
}

Once I faced the same issue. I was trying to take svn checkout using repository URL consisting of DOMAIN NAME. I tried to connect using IP address in place of DOMAIN NAME and I was able to take checkout

IMPORTANT NOTE: You should not concatenate SQL queries unless you trust the user completely. Query concatenation involves risk of SQL Injection being used to take over the world, ...khem, your database.

If you don't want to go into details how to execute query using SqlCommand then you could call the same command line like this:

string userInput = "Brian";
var process = new Process();
var startInfo = new ProcessStartInfo();
startInfo.WindowStyle = ProcessWindowStyle.Hidden;
startInfo.FileName = "cmd.exe";
startInfo.Arguments = string.Format(@"sqlcmd.exe -S .\PDATA_SQLEXPRESS -U sa -P 2BeChanged! -d PDATA_SQLEXPRESS  
     -s ; -W -w 100 -Q "" SELECT tPatCulIntPatIDPk, tPatSFirstname, tPatSName,
     tPatDBirthday  FROM  [dbo].[TPatientRaw] WHERE tPatSName = '{0}' """, userInput);

process.StartInfo = startInfo;
process.Start();

Just ensure that you escape each double quote " with ""

Version for Linux. Create a file ~/.config/sublime-text-3/Packages/User/Python3.sublime-build with the following.

 "selector": "source.python"
}

You might try reducing your base memory under settings to around 3175MB and reduce your cores to 1. That should work given that your BIOS is set for virtualization. Use the f12 key, security, virtualization to make sure that it is enabled. If it doesn't say VT-x that is ok, it should say VT-d or the like.

I just want to add, if you get this error because you are using Cygwin make and auto-generated files, you can fix it with the following sed,

sed -e 's@\\\([^ ]\)@/\1@g' -e 's@[cC]:@/cygdrive/c@' -i filename.d

You may need to add more characters than just space to the escape list in the first substitution but you get the idea. The concept here is that /cygdrive/c is an alias for c: that cygwin's make will recognize.

And may as well throw in

-e 's@^ \+@\t@'

just in case you did start with spaces on accident (although I /think/ this will usually be a "missing separator" error).

You cannot directly save a Python file as an exe and expect it to work -- the computer cannot automatically understand whatever code you happened to type in a text file. Instead, you need to use another program to transform your Python code into an exe.

I recommend using a program like Pyinstaller. It essentially takes the Python interpreter and bundles it with your script to turn it into a standalone exe that can be run on arbitrary computers that don't have Python installed (typically Windows computers, since Linux tends to come pre-installed with Python).

To install it, you can either download it from the linked website or use the command:

pip install pyinstaller

...from the command line. Then, for the most part, you simply navigate to the folder containing your source code via the command line and run:

pyinstaller myscript.py

You can find more information about how to use Pyinstaller and customize the build process via the documentation.

You don't necessarily have to use Pyinstaller, though. Here's a comparison of different programs that can be used to turn your Python code into an executable.

If you revise your regular expression like this:

drupal-6.14/(?=sites(?!/all|/default)).*
             ^^

...then it will match all inputs that contain drupal-6.14/ followed by sites followed by anything other than /all or /default. For example:

drupal-6.14/sites/foo
drupal-6.14/sites/bar
drupal-6.14/sitesfoo42
drupal-6.14/sitesall

Changing ?= to ?! to match your original regex simply negates those matches:

drupal-6.14/(?!sites(?!/all|/default)).*
             ^^

So, this simply means that drupal-6.14/ now cannot be followed by sites followed by anything other than /all or /default. So now, these inputs will satisfy the regex:

drupal-6.14/sites/all
drupal-6.14/sites/default
drupal-6.14/sites/all42

But, what may not be obvious from some of the other answers (and possibly your question) is that your regex will also permit other inputs where drupal-6.14/ is followed by anything other than sites as well. For example:

drupal-6.14/foo
drupal-6.14/xsites

Conclusion: So, your regex basically says to include all subdirectories of drupal-6.14 except those subdirectories of sites whose name begins with anything other than all or default.

I realise this is a slightly old question, but it was driving me crazy too - and today I've found the solution that I believe the questioner was looking for (i.e. a direct mapping of Excel 2003's Web-->Address to the Excel 2010 Ribbon).

To customise the Ribbon, right-click on it and choose 'Customise the Ribbon'. You can make a new tab/group, or add this to an existing one. Choose to look in "All commands" and then the one you are after is simply called "Address". This puts a box with the full network path in it (that can be selected to copy) into the ribbon, just like Excel 2003.

You can also do something like:

SELECT COUNT(DISTINCT id + name + address) FROM mytable

Why nullptr in C++11? What is it? Why is NULL not sufficient?

C++ expert Alex Allain says it perfectly here (my emphasis added in bold):

...imagine you have the following two function declarations:

void func(int n); 
void func(char *s);

func( NULL ); // guess which function gets called?

Although it looks like the second function will be called--you are, after all, passing in what seems to be a pointer--it's really the first function that will be called! The trouble is that because NULL is 0, and 0 is an integer, the first version of func will be called instead. This is the kind of thing that, yes, doesn't happen all the time, but when it does happen, is extremely frustrating and confusing. If you didn't know the details of what is going on, it might well look like a compiler bug. A language feature that looks like a compiler bug is, well, not something you want.

Enter nullptr. In C++11, nullptr is a new keyword that can (and should!) be used to represent NULL pointers; in other words, wherever you were writing NULL before, you should use nullptr instead. It's no more clear to you, the programmer, (everyone knows what NULL means), but it's more explicit to the compiler, which will no longer see 0s everywhere being used to have special meaning when used as a pointer.

Allain ends his article with:

Regardless of all this--the rule of thumb for C++11 is simply to start using nullptr whenever you would have otherwise used NULL in the past.

(My words):

Lastly, don't forget that nullptr is an object--a class. It can be used anywhere NULL was used before, but if you need its type for some reason, it's type can be extracted with decltype(nullptr), or directly described as std::nullptr_t, which is simply a typedef of decltype(nullptr).

For the record, the spring.jpa.hibernate.ddl-auto property is Spring Data JPA specific and is their way to specify a value that will eventually be passed to Hibernate under the property it knows, hibernate.hbm2ddl.auto.

The values create, create-drop, validate, and update basically influence how the schema tool management will manipulate the database schema at startup.

For example, the update operation will query the JDBC driver's API to get the database metadata and then Hibernate compares the object model it creates based on reading your annotated classes or HBM XML mappings and will attempt to adjust the schema on-the-fly.

The update operation for example will attempt to add new columns, constraints, etc but will never remove a column or constraint that may have existed previously but no longer does as part of the object model from a prior run.

Typically in test case scenarios, you'll likely use create-drop so that you create your schema, your test case adds some mock data, you run your tests, and then during the test case cleanup, the schema objects are dropped, leaving an empty database.

In development, it's often common to see developers use update to automatically modify the schema to add new additions upon restart. But again understand, this does not remove a column or constraint that may exist from previous executions that is no longer necessary.

In production, it's often highly recommended you use none or simply don't specify this property. That is because it's common practice for DBAs to review migration scripts for database changes, particularly if your database is shared across multiple services and applications.

' = "

/ = \ = \\

example :

f = open('c:\word.txt', 'r')
f = open("c:\word.txt", "r")
f = open("c:/word.txt", "r")
f = open("c:\\\word.txt", "r")

Results are the same

=>> no, they're not the same. A single backslash will escape characters. You just happen to luck out in that example because \k and \w aren't valid escapes like \t or \n or \\ or \"

If you want to use single backslashes (and have them interpreted as such), then you need to use a "raw" string. You can do this by putting an 'r' in front of the string

im_raw = r'c:\temp.txt'
non_raw = 'c:\\temp.txt'
another_way = 'c:/temp.txt'

As far as paths in Windows are concerned, forward slashes are interpreted the same way. Clearly the string itself is different though. I wouldn't guarantee that they're handled this way on an external device though.

I'm assuming as a developer, you have some degree of administrative control over your machine. If so, from the command line, run msconfig.exe. You can remove many processes from even starting, thereby eliminating the need to kill them with the above mentioned solutions.

This way is the least expensive way and always keeps your image view rounded:

class RoundedImageView: UIImageView {

    override init(frame: CGRect) {
        super.init(frame: frame)

        clipsToBounds = true
    }

    required init?(coder aDecoder: NSCoder) {
        super.init(coder: aDecoder)

        clipsToBounds = true
    }

    override func layoutSubviews() {
        super.layoutSubviews()

        assert(bounds.height == bounds.width, "The aspect ratio isn't 1/1. You can never round this image view!")

        layer.cornerRadius = bounds.height / 2
    }
}

The other answers are telling you to make views rounded based on frame calculations set in a UIViewControllers viewDidLoad() method. This isn't correct, since it isn't sure what the final frame will be.

If you have installed nodejs, then you also have npm. Npm comes with node.

You can create a custom control that inherits from the Button class. This code will be more reusable, please look at the following blog post for more details: WPF - create custom button with image (ImageButton)

Assuming your column names (df.columns) are ['index','a','b','c'], then the data you want is in the third and fourth columns. If you don't know their names when your script runs, you can do this

newdf = df[df.columns[2:4]] # Remember, Python is zero-offset! The "third" entry is at slot two.

As EMS points out in his answer, df.ix slices columns a bit more concisely, but the .columns slicing interface might be more natural, because it uses the vanilla one-dimensional Python list indexing/slicing syntax.

Warning: 'index' is a bad name for a DataFrame column. That same label is also used for the real df.index attribute, an Index array. So your column is returned by df['index'] and the real DataFrame index is returned by df.index. An Index is a special kind of Series optimized for lookup of its elements' values. For df.index it's for looking up rows by their label. That df.columns attribute is also a pd.Index array, for looking up columns by their labels.

While adding layer.cornerRadius in the storyboard make sure that you don't have leading or trailing spaces. If you do copy paste, you might get spaces inserted. Would be nice if XCode say some kind of warning or error.

don't worry about FLASH_MODE_OFF because this will keep the light on, strange but it's true

to turn off the led just release the camera

Make sure your iframe is already loaded. Old but reliable way without jQuery:

<iframe src="samedomain.com/page.htm" id="iframe" onload="access()"></iframe>

<script>
function access() {
   var iframe = document.getElementById("iframe");
   var innerDoc = iframe.contentDocument || iframe.contentWindow.document;
   console.log(innerDoc.body);
}
</script>

I did not modify your code for this solution, I wrote my own instead. My solution isn't quite what you asked for, but maybe you could build on it with existing knowledge. I commented the code as well so you know what exactly I'm doing with the changes.

As a solution to "avoid setting the height in JavaScript", I just made 'maxHeight' a parameter in the JS function called toggleHeight. Now it can be set in the HTML for each div of class expandable.

I'll say this up front, I'm not super experienced with front-end languages, and there's an issue where I need to click the 'Show/hide' button twice initially before the animation starts. I suspect it's an issue with focus.

The other issue with my solution is that you can actually figure out what the hidden text is without pressing the show/hide button just by clicking in the div and dragging down, you can highlight the text that's not visible and paste it to a visible space.

My suggestion for a next step on top of what I've done is to make it so that the show/hide button changes dynamically. I think you can figure out how to do that with what you already seem to know about showing and hiding text with JS.

An addition to Christopher Bradford's answer to use the HTML escaping anywhere, since most people don't use CGI nowadays, you can also use Rack:

require 'rack/utils'
Rack::Utils.escape_html('Usage: foo "bar" <baz>')

If you're trying to find an element by id, you don't need to search the table only - it should be unique on the page, and so you should be able to use:

var verificaHorario = $('#' + horaInicial);

If you need to search only in the table for whatever reason, you can use:

var verificaHorario = $("#tbIntervalos").find("td#" + horaInicial)

Let me post a solution here for C++03 that I consider the cleanest possible.*

#define DECLARE_LAMBDA(NAME, RETURN_TYPE, FUNCTION) \
    struct { RETURN_TYPE operator () FUNCTION } NAME;

...

int main(){
  DECLARE_LAMBDA(demoLambda, void, (){ cout<<"I'm a lambda!"<<endl; });
  demoLambda();

  DECLARE_LAMBDA(plus, int, (int i, int j){
    return i+j;
  });
  cout << "plus(1,2)=" << plus(1,2) << endl;
  return 0;
}

(*) in the C++ world using macros is never considered clean.

It means you allow every (*) user-agent/crawler to access the root (/) of your site. You're okay.

You're saying you have this:

char array[20]; char string[100];
array[0]='1'; 
array[1]='7'; 
array[2]='8'; 
array[3]='.'; 
array[4]='9';

And you'd like to have this:

string[0]= "178.9"; // where it was stored 178.9 ....in position [0]

You can't have that. A char holds 1 character. That's it. A "string" in C is an array of characters followed by a sentinel character (NULL terminator).

Now if you want to copy the first x characters out of array to string you can do that with memcpy():

memcpy(string, array, x);
string[x] = '\0';

We tried several things before arriving at an acceptable solution:

xxd -u /usr/bin/xxd | grep 'DF'
00017b0: 4010 8D05 0DFF FF0A 0300 53E3 0610 A003  @.........S.....


root# grep -ibH "df" /usr/bin/xxd
Binary file /usr/bin/xxd matches
xxd -u /usr/bin/xxd | grep -H 'DF'
(standard input):00017b0: 4010 8D05 0DFF FF0A 0300 53E3 0610 A003  @.........S.....

Then found we could get usable results with

xxd -u /usr/bin/xxd > /tmp/xxd.hex ; grep -H 'DF' /tmp/xxd

Note that using a simple search target like 'DF' will incorrectly match characters that span across byte boundaries, i.e.

xxd -u /usr/bin/xxd | grep 'DF'
00017b0: 4010 8D05 0DFF FF0A 0300 53E3 0610 A003  @.........S.....
--------------------^^

So we use an ORed regexp to search for ' DF' OR 'DF ' (the searchTarget preceded or followed by a space char).

The final result seems to be

xxd -u -ps -c 10000000000 DumpFile > DumpFile.hex
egrep ' DF|DF ' Dumpfile.hex

Couple of problems:

The while should be a for You are not returning a value but you have declared a return type of double

double average = sum / data.length;;

sum and data.length are both ints so the division will return an int - check your types

double semi-colon, probably won't break it, just looks odd.

When you get this error, it means that code you are using makes a reference to an type that is in an assembly, but the assembly is not part of your project so it can't use it.

Deleting Project.Rights.dll is the opposite of what you want. You need to make sure your project can reference the assembly. So it must either be placed in the Global Assembly Cache or your web application's ~/Bin directory.

Edit-If you don't want to use the assembly, then deleting it is not the proper solution either. Instead, you must remove all references to it in your code. Since the assembly isn't directly needed by code you've written, but instead by something else you're referencing, you'll have to replace that referenced assembly with something that doesn't have Project.Rights.dll as a dependency.

I know this thread is two years old now, I still don't see a correct answer here.

Unless you want to use Joda or have Java 8 and if you need to subract dates influenced by daylight saving.

So I have written my own solution. The important aspect is that it only works if you really only care about dates because it's necessary to discard the time information, so if you want something like 25.06.2014 - 01.01.2010 = 1636, this should work regardless of the DST:

private static SimpleDateFormat simpleDateFormat = new SimpleDateFormat("dd.MM.yyyy");

public static long getDayCount(String start, String end) {
  long diff = -1;
  try {
    Date dateStart = simpleDateFormat.parse(start);
    Date dateEnd = simpleDateFormat.parse(end);

    //time is always 00:00:00, so rounding should help to ignore the missing hour when going from winter to summer time, as well as the extra hour in the other direction
    diff = Math.round((dateEnd.getTime() - dateStart.getTime()) / (double) 86400000);
  } catch (Exception e) {
    //handle the exception according to your own situation
  }
  return diff;
}

As the time is always 00:00:00, using double and then Math.round() should help to ignore the missing 3600000 ms (1 hour) when going from winter to summer time, as well as the extra hour if going from summer to winter.

This is a small JUnit4 test I use to prove it:

@Test
public void testGetDayCount() {
  String startDateStr = "01.01.2010";
  GregorianCalendar gc = new GregorianCalendar(locale);
  try {
    gc.setTime(simpleDateFormat.parse(startDateStr));
  } catch (Exception e) {
  }

  for (long i = 0; i < 10000; i++) {
    String dateStr = simpleDateFormat.format(gc.getTime());
    long dayCount = getDayCount(startDateStr, dateStr);
    assertEquals("dayCount must be equal to the loop index i: ", i, dayCount);
    gc.add(GregorianCalendar.DAY_OF_YEAR, 1);
  }
}

... or if you want to see what it does 'life', replace the assertion with just:

System.out.println("i: " + i + " | " + dayCount + " - getDayCount(" + startDateStr + ", " + dateStr + ")");

... and this is what the output should look like:

  i: 0 | 0  - getDayCount(01.01.2010, 01.01.2010)
  i: 1 | 1  - getDayCount(01.01.2010, 02.01.2010)
  i: 2 | 2  - getDayCount(01.01.2010, 03.01.2010)
  i: 3 | 3  - getDayCount(01.01.2010, 04.01.2010)
  ...
  i: 1636 | 1636  - getDayCount(01.01.2010, 25.06.2014)
  ...
  i: 9997 | 9997  - getDayCount(01.01.2010, 16.05.2037)
  i: 9998 | 9998  - getDayCount(01.01.2010, 17.05.2037)
  i: 9999 | 9999  - getDayCount(01.01.2010, 18.05.2037)

Fast-forward merging makes sense for short-lived branches, but in a more complex history, non-fast-forward merging may make the history easier to understand, and make it easier to revert a group of commits.

Warning: Non-fast-forwarding has potential side effects as well. Please review https://sandofsky.com/blog/git-workflow.html, avoid the 'no-ff' with its "checkpoint commits" that break bisect or blame, and carefully consider whether it should be your default approach for master.

^{(From nvie.com, Vincent Driessen, post "A successful Git branching model")}

Incorporating a finished feature on develop

Finished features may be merged into the develop branch to add them to the upcoming release:

$ git checkout develop
Switched to branch 'develop'
$ git merge --no-ff myfeature
Updating ea1b82a..05e9557
(Summary of changes)
$ git branch -d myfeature
Deleted branch myfeature (was 05e9557).
$ git push origin develop

The --no-ff flag causes the merge to always create a new commit object, even if the merge could be performed with a fast-forward. This avoids losing information about the historical existence of a feature branch and groups together all commits that together added the feature.

Jakub Narebski also mentions the config merge.ff:

By default, Git does not create an extra merge commit when merging a commit that is a descendant of the current commit. Instead, the tip of the current branch is fast-forwarded.
When set to false, this variable tells Git to create an extra merge commit in such a case (equivalent to giving the --no-ff option from the command line).
When set to 'only', only such fast-forward merges are allowed (equivalent to giving the --ff-only option from the command line).

The fast-forward is the default because:

• short-lived branches are very easy to create and use in Git
• short-lived branches often isolate many commits that can be reorganized freely within that branch
• those commits are actually part of the main branch: once reorganized, the main branch is fast-forwarded to include them.

But if you anticipate an iterative workflow on one topic/feature branch (i.e., I merge, then I go back to this feature branch and add some more commits), then it is useful to include only the merge in the main branch, rather than all the intermediate commits of the feature branch.

In this case, you can end up setting this kind of config file:

[branch "master"]
# This is the list of cmdline options that should be added to git-merge 
# when I merge commits into the master branch.

# The option --no-commit instructs git not to commit the merge
# by default. This allows me to do some final adjustment to the commit log
# message before it gets commited. I often use this to add extra info to
# the merge message or rewrite my local branch names in the commit message
# to branch names that are more understandable to the casual reader of the git log.

# Option --no-ff instructs git to always record a merge commit, even if
# the branch being merged into can be fast-forwarded. This is often the
# case when you create a short-lived topic branch which tracks master, do
# some changes on the topic branch and then merge the changes into the
# master which remained unchanged while you were doing your work on the
# topic branch. In this case the master branch can be fast-forwarded (that
# is the tip of the master branch can be updated to point to the tip of
# the topic branch) and this is what git does by default. With --no-ff
# option set, git creates a real merge commit which records the fact that
# another branch was merged. I find this easier to understand and read in
# the log.

mergeoptions = --no-commit --no-ff

The OP adds in the comments:

I see some sense in fast-forward for [short-lived] branches, but making it the default action means that git assumes you... often have [short-lived] branches. Reasonable?

Jefromi answers:

I think the lifetime of branches varies greatly from user to user. Among experienced users, though, there's probably a tendency to have far more short-lived branches.

To me, a short-lived branch is one that I create in order to make a certain operation easier (rebasing, likely, or quick patching and testing), and then immediately delete once I'm done.
That means it likely should be absorbed into the topic branch it forked from, and the topic branch will be merged as one branch. No one needs to know what I did internally in order to create the series of commits implementing that given feature.

More generally, I add:

it really depends on your development workflow:

• if it is linear, one branch makes sense.
• If you need to isolate features and work on them for a long period of time and repeatedly merge them, several branches make sense.

See "When should you branch?"

Actually, when you consider the Mercurial branch model, it is at its core one branch per repository (even though you can create anonymous heads, bookmarks and even named branches)
See "Git and Mercurial - Compare and Contrast".

Mercurial, by default, uses anonymous lightweight codelines, which in its terminology are called "heads".
Git uses lightweight named branches, with injective mapping to map names of branches in remote repository to names of remote-tracking branches.
Git "forces" you to name branches (well, with the exception of a single unnamed branch, which is a situation called a "detached HEAD"), but I think this works better with branch-heavy workflows such as topic branch workflow, meaning multiple branches in a single repository paradigm.

Here's my Swiss® Army Knife of string-tokenizers for splitting up strings by whitespace, accounting for single and double-quote wrapped strings as well as stripping those characters from the results. I used RegexBuddy 4.x to generate most of the code-snippet, but I added custom handling for stripping quotes and a few other things.

#include <string>
#include <locale>
#include <regex>

std::vector<std::wstring> tokenize_string(std::wstring string_to_tokenize) {
    std::vector<std::wstring> tokens;

    std::wregex re(LR"(("[^"]*"|'[^']*'|[^"' ]+))", std::regex_constants::collate);

    std::wsregex_iterator next( string_to_tokenize.begin(),
                                string_to_tokenize.end(),
                                re,
                                std::regex_constants::match_not_null );

    std::wsregex_iterator end;
    const wchar_t single_quote = L'\'';
    const wchar_t double_quote = L'\"';
    while ( next != end ) {
        std::wsmatch match = *next;
        const std::wstring token = match.str( 0 );
        next++;

        if (token.length() > 2 && (token.front() == double_quote || token.front() == single_quote))
            tokens.emplace_back( std::wstring(token.begin()+1, token.begin()+token.length()-1) );
        else
            tokens.emplace_back(token);
    }
    return tokens;
}

Float the image right, which will at first cause your text to wrap around it.

Then whatever the very next element is, set it to { clear: right; } and everything will stop wrapping around the image.

From man 7 gitrevisions:

HEAD names the commit on which you based the changes in the working tree. FETCH_HEAD records the branch which you fetched from a remote repository with your last git fetch invocation. ORIG_HEAD is created by commands that move your HEAD in a drastic way, to record the position of the HEAD before their operation, so that you can easily change the tip of the branch back to the state before you ran them. MERGE_HEAD records the commit(s) which you are merging into your branch when you run git merge. CHERRY_PICK_HEAD records the commit which you are cherry-picking when you run git cherry-pick.

Are you missing the reference to System.Configuration.dll? ConfigurationManager class lies there.

EDIT: The System.Configuration namespace has classes in mscorlib.dll, system.dll and in system.configuration.dll. Your project always include the mscorlib.dll and system.dll references, but system.configuration.dll must be added to most project types, as it's not there by default...

When using Flask (I am using it with flat pages)... I found that enabling explicitly (was not by default for some reason) 'attr_list' in extensions within the call to markdown does the trick - and then one can use the attributes (very useful also to access CSS - class="my class" for example...).

FLATPAGES_HTML_RENDERER = prerender_jinja

and the function:

def prerender_jinja(text):
    prerendered_body = render_template_string(Markup(text))
    pygmented_body   = markdown.markdown(prerendered_body, extensions=['codehilite', 'fenced_code', 'tables', 'attr_list'])
    return pygmented_body

And then in Markdown:

![image](https://octodex.github.com/images/yaktocat.png "This is a tooltip"){: width=200px}

Quick:

var siblings = n => [...n.parentElement.children].filter(c=>c!=n)

https://codepen.io/anon/pen/LLoyrP?editors=1011

Get the parent's children as an array, filter out this element.

Edit:

And to filter out text nodes (Thanks pmrotule):

var siblings = n => [...n.parentElement.children].filter(c=>c.nodeType == 1 && c!=n)

I also meet this issue while I used the following code:

window.open('test.html','Window title','width=1200,height=800,scrollbars=yes');

but when I delete the blank space of the "Window title" the below code is working:

window.open('test.html','Windowtitle','width=1200,height=800,scrollbars=yes');

I tried the above pieces of code but I did not do any streaming.

sudo rabbitmqctl list_queues | awk '{print $1}' > queues.txt; for line in $(cat queues.txt); do sudo rabbitmqctl delete_queue "$line"; done.

I generate a file that contains all the queue names and loops through it line by line to the delete them. For the loops, while read ... did not do it for me. It was always stopping at the first queue name.

I used Jackson to convert Java Object to JSON string and send as follows.

PrintWriter out = response.getWriter();
ObjectMapper objectMapper= new ObjectMapper();
String jsonString = objectMapper.writeValueAsString(MyObject);
response.setContentType("application/json");
response.setCharacterEncoding("UTF-8");
out.print(jsonString);
out.flush();

you can try

position: relative;
bottom: 20px;

but I don't see a problem on my browser (Google Chrome)

The way you have used the HTML syntax is problematic.

This is how the syntax should be

style="property1:value1;property2:value2"

In your case, this will be the way to do

<h2 style="text-align :center; font-family :tahoma" >TITLE</h2>

A further example would be as follows

<div class ="row">
    <button type="button" style= "margin-top : 20px; border-radius: 15px" 
    class="btn btn-primary">View Full Profile</button>
</div>

Here is a native solution for PowerShell v5, using the cmdlet Compress-Archive Creating Zip files using PowerShell.

See also the Microsoft Docs for Compress-Archive.

Example 1:

Compress-Archive `
    -LiteralPath C:\Reference\Draftdoc.docx, C:\Reference\Images\diagram2.vsd `
    -CompressionLevel Optimal `
    -DestinationPath C:\Archives\Draft.Zip

Example 2:

Compress-Archive `
    -Path C:\Reference\* `
    -CompressionLevel Fastest `
    -DestinationPath C:\Archives\Draft

Example 3:

Write-Output $files | Compress-Archive -DestinationPath $outzipfile

var output = [];

$.each(selectValues, function(key, value)
{
  output.push('<option value="'+ key +'">'+ value +'</option>');
});

$('#mySelect').html(output.join(''));

In this way you "touch the DOM" only one time.

I'm not sure if the latest line can be converted into $('#mySelect').html(output.join('')) because I don't know jQuery internals (maybe it does some parsing in the html() method)

The reason the code in your question does not authenticate is because you are sending the auth in the data object, not in the config, which will put it in the headers. Per the axios docs, the request method alias for post is:

axios.post(url[, data[, config]])

Therefore, for your code to work, you need to send an empty object for data:

var session_url = 'http://api_address/api/session_endpoint';
var username = 'user';
var password = 'password';
var basicAuth = 'Basic ' + btoa(username + ':' + password);
axios.post(session_url, {}, {
  headers: { 'Authorization': + basicAuth }
}).then(function(response) {
  console.log('Authenticated');
}).catch(function(error) {
  console.log('Error on Authentication');
});

The same is true for using the auth parameter mentioned by @luschn. The following code is equivalent, but uses the auth parameter instead (and also passes an empty data object):

var session_url = 'http://api_address/api/session_endpoint';
var uname = 'user';
var pass = 'password';
axios.post(session_url, {}, {
  auth: {
    username: uname,
    password: pass
  }
}).then(function(response) {
  console.log('Authenticated');
}).catch(function(error) {
  console.log('Error on Authentication');
});

In Python 2, I didn't have a lot luck with super(). I used the answer from jimifiki on this SO thread how to refer to a parent method in python?. Then, I added my own little twist to it, which I think is an improvement in usability (Especially if you have long class names).

Define the base class in one module:

 # myA.py

class A():     
    def foo( self ):
        print "foo"

Then import the class into another modules as parent:

# myB.py

from myA import A as parent

class B( parent ):
    def foo( self ):
        parent.foo( self )   # calls 'A.foo()'

give on .view-type class float:left; or delete the float:right; of .view-name

edit: Wrap your div <div class="view-row"> with another div for example <div class="table">

and set the following css :

.table {
    display:table;
    width:100%;}

You have to use the table structure for correct results.

This is bit improvement over accepted answer from @mdb. Specifically, we also capture error output of the process. Additionally, we capture these outputs through events because ReadToEnd() doesn't work if you want to capture both error and regular output. It took me while to make this work because it actually also requires BeginxxxReadLine() calls after Start().

Asynchronous way:

using System.Diagnostics;

Process process = new Process();

void LaunchProcess()
{
    process.EnableRaisingEvents = true;
    process.OutputDataReceived += new System.Diagnostics.DataReceivedEventHandler(process_OutputDataReceived);
    process.ErrorDataReceived += new System.Diagnostics.DataReceivedEventHandler(process_ErrorDataReceived);
    process.Exited += new System.EventHandler(process_Exited);

    process.StartInfo.FileName = "some.exe";
    process.StartInfo.Arguments = "param1 param2";
    process.StartInfo.UseShellExecute = false;
    process.StartInfo.RedirectStandardError = true;
    process.StartInfo.RedirectStandardOutput = true;

    process.Start();
    process.BeginErrorReadLine();
    process.BeginOutputReadLine();          

    //below line is optional if we want a blocking call
    //process.WaitForExit();
}

void process_Exited(object sender, EventArgs e)
{
    Console.WriteLine(string.Format("process exited with code {0}\n", process.ExitCode.ToString()));
}

void process_ErrorDataReceived(object sender, DataReceivedEventArgs e)
{
    Console.WriteLine(e.Data + "\n");
}

void process_OutputDataReceived(object sender, DataReceivedEventArgs e)
{
    Console.WriteLine(e.Data + "\n");
}

It depends exactly what you're defining as "ASCII", but I would suggest trying a variant of a query like this:

SELECT * FROM tableName WHERE columnToCheck NOT REGEXP '[A-Za-z0-9]';

That query will return all rows where columnToCheck contains any non-alphanumeric characters. If you have other characters that are acceptable, add them to the character class in the regular expression. For example, if periods, commas, and hyphens are OK, change the query to:

SELECT * FROM tableName WHERE columnToCheck NOT REGEXP '[A-Za-z0-9.,-]';

The most relevant page of the MySQL documentation is probably 12.5.2 Regular Expressions.

Simple. In the print, do:

print(foobar.__dict__)

as long as the constructor is

__init__

const a = {
  foods: {
    dinner: 'Pasta'
  }
}
let b = JSON.parse(JSON.stringify(a))
b.foods.dinner = 'Soup'
console.log(b.foods.dinner) // Soup
console.log(a.foods.dinner) // Pasta

Using JSON.stringify and JSON.parse is the best way. Because by using the spread operator we will not get the efficient answer when the json object contains another object inside it. we need to manually specify that.

In case you need more shorting your code, you can creating new type for helper

type Strings []string

func (ss Strings) ToInterfaceSlice() []interface{} {
    iface := make([]interface{}, len(ss))
    for i := range ss {
        iface[i] = ss[i]
    }
    return iface
}

then

a := []strings{"a", "b", "c", "d"}
sliceIFace := Strings(a).ToInterfaceSlice()

the articles posted by Ricky are very good, but unfortunately they don't answer your question.

To solve your problem you should try this piece of code:

ExeConfigurationFileMap configMap = new ExeConfigurationFileMap();
configMap.ExeConfigFilename = @"d:\test\justAConfigFile.config.whateverYouLikeExtension";
Configuration config = ConfigurationManager.OpenMappedExeConfiguration(configMap, ConfigurationUserLevel.None);

If need to access a value within the config you can use the index operator:

config.AppSettings.Settings["test"].Value;

There are at least three very good reasons for using the Visitor Pattern:

1. Reduce proliferation of code which is only slightly different when data structures change.

2. Apply the same computation to several data structures, without changing the code which implements the computation.

3. Add information to legacy libraries without changing the legacy code.

Please have a look at an article I've written about this.

Bad: (jsHint will throw a error)

for (var name in item) {
    console.log(item[name]);
}

Good:

for (var name in item) {
  if (item.hasOwnProperty(name)) {
    console.log(item[name]);
  }
}

You don't need a class, an object or a companion object for declaring constants in Kotlin. You can just declare a file holding all the constants (for example Constants.kt or you can also put them inside any existing Kotlin file) and directly declare the constants inside the file. The constants known at compile time must be marked with const.

So, in this case, it should be:

const val MY_CONST = "something"

and then you can import the constant using:

import package_name.MY_CONST

As an empty string is not valid JSON it would be incorrect for JSON.parse('') to return null because "null" is valid JSON. e.g.

JSON.parse("null");

returns null. It would be a mistake for invalid JSON to also be parsed to null.

While an empty string is not valid JSON two quotes is valid JSON. This is an important distinction.

Which is to say a string that contains two quotes is not the same thing as an empty string.

JSON.parse('""');

will parse correctly, (returning an empty string). But

JSON.parse('');

will not.

Valid minimal JSON strings are

The empty object '{}'

The empty array '[]'

The string that is empty '""'

A number e.g. '123.4'

The boolean value true 'true'

The boolean value false 'false'

The null value 'null'

Try using

$var = @($val1 / $val2);

  curl_setopt($curl, CURLOPT_TIMEOUT, 10); 

  $html = curl_exec($curl); // execute the curl command 
  curl_close($curl); // close the connection 

  return $html; // and finally, return $html

You can wrap the Promise in a class.

class Deferred {
    constructor(handler) {
        this.promise = new Promise((resolve, reject) => {
            this.reject = reject;
            this.resolve = resolve;
            handler(resolve, reject);
        });

        this.promise.resolve = this.resolve;
        this.promise.reject = this.reject;

        return this.promise;
    }
    promise;
    resolve;
    reject;
}

// How to use.
const promise = new Deferred((resolve, reject) => {
  // Use like normal Promise.
});

promise.resolve(); // Resolve from any context.

You are facing issue in

 s1.name="Paolo";

because, in the LHS, you're using an array type, which is not assignable.

To elaborate, from C11, chapter §6.5.16

assignment operator shall have a modifiable lvalue as its left operand.

and, regarding the modifiable lvalue, from chapter §6.3.2.1

A modifiable lvalue is an lvalue that does not have array type, [...]

You need to use strcpy() to copy into the array.

That said, data s1 = {"Paolo", "Rossi", 19}; works fine, because this is not a direct assignment involving assignment operator. There we're using a brace-enclosed initializer list to provide the initial values of the object. That follows the law of initialization, as mentioned in chapter §6.7.9

Each brace-enclosed initializer list has an associated current object. When no designations are present, subobjects of the current object are initialized in order according to the type of the current object: array elements in increasing subscript order, structure members in declaration order, and the first named member of a union.[....]

You could add a compact method to Hash like this

class Hash
  def compact
    delete_if { |k, v| v.nil? }
  end
end

or for a version that supports recursion

class Hash
  def compact(opts={})
    inject({}) do |new_hash, (k,v)|
      if !v.nil?
        new_hash[k] = opts[:recurse] && v.class == Hash ? v.compact(opts) : v
      end
      new_hash
    end
  end
end

I would create a user control which holds a Label and a Text Box in it and simply create instances of that user control 'n' times. If you want to know a better way to do it and use properties to get access to the values of Label and Text Box from the user control, please let me know.

Simple way to do it would be:

int n = 4; // Or whatever value - n has to be global so that the event handler can access it

private void btnDisplay_Click(object sender, EventArgs e)
{
    TextBox[] textBoxes = new TextBox[n];
    Label[] labels = new Label[n];

    for (int i = 0; i < n; i++)
    {
        textBoxes[i] = new TextBox();
        // Here you can modify the value of the textbox which is at textBoxes[i]

        labels[i] = new Label();
        // Here you can modify the value of the label which is at labels[i]
    }

    // This adds the controls to the form (you will need to specify thier co-ordinates etc. first)
    for (int i = 0; i < n; i++)
    {
        this.Controls.Add(textBoxes[i]);
        this.Controls.Add(labels[i]);
    }
}

The code above assumes that you have a button btnDisplay and it has a onClick event assigned to btnDisplay_Click event handler. You also need to know the value of n and need a way of figuring out where to place all controls. Controls should have a width and height specified as well.

To do it using a User Control simply do this.

Okay, first of all go and create a new user control and put a text box and label in it.

Lets say they are called txtSomeTextBox and lblSomeLabel. In the code behind add this code:

public string GetTextBoxValue() 
{ 
    return this.txtSomeTextBox.Text; 
} 

public string GetLabelValue() 
{ 
    return this.lblSomeLabel.Text; 
} 

public void SetTextBoxValue(string newText) 
{ 
    this.txtSomeTextBox.Text = newText; 
} 

public void SetLabelValue(string newText) 
{ 
    this.lblSomeLabel.Text = newText; 
}

Now the code to generate the user control will look like this (MyUserControl is the name you have give to your user control):

private void btnDisplay_Click(object sender, EventArgs e)
{
    MyUserControl[] controls = new MyUserControl[n];

    for (int i = 0; i < n; i++)
    {
        controls[i] = new MyUserControl();

        controls[i].setTextBoxValue("some value to display in text");
        controls[i].setLabelValue("some value to display in label");
        // Now if you write controls[i].getTextBoxValue() it will return "some value to display in text" and controls[i].getLabelValue() will return "some value to display in label". These value will also be displayed in the user control.
    }

    // This adds the controls to the form (you will need to specify thier co-ordinates etc. first)
    for (int i = 0; i < n; i++)
    {
        this.Controls.Add(controls[i]);
    }
}

Of course you can create more methods in the usercontrol to access properties and set them. Or simply if you have to access a lot, just put in these two variables and you can access the textbox and label directly:

public TextBox myTextBox;
public Label myLabel;

In the constructor of the user control do this:

myTextBox = this.txtSomeTextBox;
myLabel = this.lblSomeLabel;

Then in your program if you want to modify the text value of either just do this.

control[i].myTextBox.Text = "some random text"; // Same applies to myLabel

Hope it helped :)

Use jQuery DataTables plug-in, it supports fixed header and columns. This example adds fixed column support to the html table "example":

http://datatables.net/extensions/fixedcolumns/

For two fixed columns:

http://www.datatables.net/release-datatables/extensions/FixedColumns/examples/two_columns.html

colorRampPalette could be your friend here:

colfunc <- colorRampPalette(c("black", "white"))
colfunc(10)
# [1] "#000000" "#1C1C1C" "#383838" "#555555" "#717171" "#8D8D8D" "#AAAAAA"
# [8] "#C6C6C6" "#E2E2E2" "#FFFFFF"

And just to show it works:

plot(rep(1,10),col=colfunc(10),pch=19,cex=3)

    SELECT art.* , sec.section.title, cat.title, use1.name, use2.name as modifiedby
FROM article art
INNER JOIN section sec ON art.section_id = sec.section.id
INNER JOIN category cat ON art.category_id = cat.id
INNER JOIN user use1 ON art.author_id = use1.id
LEFT JOIN user use2 ON art.modified_by = use2.id
WHERE art.id = '1';

Hope This Might Help

The concat protocol described here; https://trac.ffmpeg.org/wiki/Concatenate#protocol

When implemented using named pipes to avoid intermediate files

Is very fast (read: instant), has no frames dropped, and works well.

Remember to delete the named pipe files and remember to check if the video is H264 and AAC which you can do with just ffmpeg -i filename.mp4 (check for h264 and aac mentions)

Datatable.Clone is slow for large tables. I'm currently using this:

Dim target As DataTable = 
    New DataView(source, "1=2", Nothing, DataViewRowState.CurrentRows)
    .ToTable()

Note that this only copies the structure of source table, not the data.

If you are using Bootstrap, look at padding of your tds.

Here's why I like the 80-character with: at work I use Vim and work on two files at a time on a monitor running at, I think, 1680x1040 (I can never remember). If the lines are any longer, I have trouble reading the files, even when using word wrap. Needless to say, I hate dealing with other people's code as they love long lines.

I recently discovered a specialized class that's awesome for a bulk insert (ODP.NET). Oracle.DataAccess.Client.OracleBulkCopy! It takes a datatable as a parameter, then you call WriteTOServer method...it is very fast and effective, good luck!!

one has not been assigned so points to an unpredictable location. You should either place it on the stack:

Vector one;
one.a = 12;
one.b = 13;
one.c = -11

or dynamically allocate memory for it:

Vector* one = malloc(sizeof(*one))
one->a = 12;
one->b = 13;
one->c = -11
free(one);

Note the use of free in this case. In general, you'll need exactly one call to free for each call made to malloc.

I don't know if this exists in Visual Studio 2008 but in Visual Studio 2010+ you can easily do this by:

Don't select anything, then press Ctrl + C And then (without doing anything else) Ctrl + V

You can use the following time conversion within SQL like this:

--Convert Time to Integer (Minutes)
DECLARE @timeNow datetime = '14:47'
SELECT DATEDIFF(mi,CONVERT(datetime,'00:00',108), CONVERT(datetime, RIGHT(CONVERT(varchar, @timeNow, 100),7),108))

--Convert Minutes to Time
DECLARE @intTime int = (SELECT DATEDIFF(mi,CONVERT(datetime,'00:00',108), CONVERT(datetime, RIGHT(CONVERT(varchar, @timeNow, 100),7),108)))
SELECT DATEADD(minute, @intTime, '')

Result: 887 <- Time in minutes and 1900-01-01 14:47:00.000 <-- Minutes to time

In theory, according to RFC 4329, application/javascript.

The reason it is supposed to be application is not anything to do with whether the type is readable or executable. It's because there are custom charset-determination mechanisms laid down by the language/type itself, rather than just the generic charset parameter. A subtype of text should be capable of being transcoded by a proxy to another charset, changing the charset parameter. This is not true of JavaScript because:

a. the RFC says user-agents should be doing BOM-sniffing on the script to determine type (I'm not sure if any browsers actually do this though);

b. browsers use other information—the including page's encoding and in some browsers the script charset attribute—to determine the charset. So any proxy that tried to transcode the resource would break its users. (Of course in reality no-one ever uses transcoding proxies anyway, but that was the intent.)

Therefore the exact bytes of the file must be preserved exactly, which makes it a binary application type and not technically character-based text.

For the same reason, application/xml is officially preferred over text/xml: XML has its own in-band charset signalling mechanisms. And everyone ignores application for XML, too.

text/javascript and text/xml may not be the official Right Thing, but there are what everyone uses today for compatibility reasons, and the reasons why they're not the right thing are practically speaking completely unimportant.

int64_t is guaranteed by the C99 standard to be exactly 64 bits wide on platforms that implement it, there's no such guarantee for a long which is at least 32 bits so it could be more.

§7.18.1.3 Exact-width integer types 1 The typedef name intN_t designates a signed integer type with width N , no padding bits, and a two’s complement representation. Thus, int8_t denotes a signed integer type with a width of exactly 8 bits.

It has a -force parameter.????

Instead of sudo, try

su - username command

In my experience, sudo is not always available on RHEL systems, but su is, because su is part of the coreutils package whereas sudo is in the sudo package.

Ensure that all the libraries you're using in your project are not being referenced from other project int the workspace. That was my problem.

I added +/- 10-15% efficiency to the selected answer by minor code refactoring and moving the recursive function outside of the function namespace.

See my question: Are namespaced functions reevaluated on every call? for why this slows nested functions down.

function _flatten (target, obj, path) {
  var i, empty;
  if (obj.constructor === Object) {
    empty = true;
    for (i in obj) {
      empty = false;
      _flatten(target, obj[i], path ? path + '.' + i : i);
    }
    if (empty && path) {
      target[path] = {};
    }
  } 
  else if (obj.constructor === Array) {
    i = obj.length;
    if (i > 0) {
      while (i--) {
        _flatten(target, obj[i], path + '[' + i + ']');
      }
    } else {
      target[path] = [];
    }
  }
  else {
    target[path] = obj;
  }
}

function flatten (data) {
  var result = {};
  _flatten(result, data, null);
  return result;
}

Older versions of Git used to allow pushes to the currently checked out branch of a non-bare repository.

It turns out this was a terribly confusing thing to allow. So they added the warning message you see, which is also terribly confusing.

If the first repository is just acting as a server then convert it to a bare repository as the other answers recommend and be done with it.

If however you need to have a shared branch between two repos that are both in use you can achieve it with the following setup

Repo1 - will act as the server and also be used for development

Repo2 - will be for development only

Setup Repo1 as follows

Create a branch to share work on.

git branch shared_branch

To be safe, you should also create a $(REPO).git/hooks/update that rejects any changes to anything other than shared_branch, because you don't want people mucking with your private branches.

repo1/.git/hooks  (GIT_DIR!)$ cat update
#!/bin/sh
refname="$1"
oldrev="$2"
newrev="$3"

if [ "${refname}" != "refs/heads/shared_branch" ]
then
   echo "You can only push changes to shared_branch, you cannot push to ${refname}"
   exit 1
fi

Now create a local branch in repo1 where you will do your actual work.

git checkout -b my_work --track shared_branch
Branch my_work set up to track local branch shared_branch.
Switched to a new branch 'my_work'

(may need to git config --global push.default upstream in order for git push to work)

Now you can create repo2 with

git clone path/to/repo1 repo2 
git checkout shared_branch 

At this point you have both repo1 and repo2 setup to work on local branches that push and pull from shared_branch in repo1, without needing to worry about that error message or having the working directory get out of sync in repo1. Whatever normal workflow you use should work.

You probably want to pass "a" as the mode argument. See the docs for open().

with open("foo", "a") as f:
    f.write("cool beans...")

There are other permutations of the mode argument for updating (+), truncating (w) and binary (b) mode but starting with just "a" is your best bet.

If you want to do it in a tidyverse manner, try add_column from tibble, which allows you to specifiy where to place the new column with .before or .after parameter:

library(tibble)

df <- data.frame(b = c(1, 1, 1), c = c(2, 2, 2), d = c(3, 3, 3))
add_column(df, a = 0, .before = 1)

#   a b c d
# 1 0 1 2 3
# 2 0 1 2 3
# 3 0 1 2 3

Abramov's goal - and everyone's ideally - is simply to encapsulate complexity (and async calls) in the place where it's most appropriate.

Where's the best place to do that in the standard Redux dataflow? How about:

• Reducers? No way. They should be pure functions with no side-effects. Updating the store is serious, complicated business. Don't contaminate it.
• Dumb View Components? Definitely No. They have one concern: presentation and user-interaction, and should be as simple as possible.
• Container Components? Possible, but sub-optimal. It makes sense in that the container is a place where we encapsulate some view related complexity and interact with the store, but:
  • Containers do need to be more complex than dumb components, but it's still a single responsibility: providing bindings between view and state/store. Your async logic is a whole separate concern from that.
  • By placing it in a container, you'd be locking your async logic into a single context, for a single view/route. Bad idea. Ideally it's all reusable, and totally decoupled.
• Some other Service Module? Bad idea: you'd need to inject access to the store, which is a maintainability/testability nightmare. Better to go with the grain of Redux and access the store only using the APIs/models provided.
• Actions and the Middlewares that interpret them? Why not?! For starters, it's the only major option we have left. :-) More logically, the action system is decoupled execution logic that you can use from anywhere. It's got access to the store and can dispatch more actions. It has a single responsibility which is to organize the flow of control and data around the application, and most async fits right into that.
  • What about the Action Creators? Why not just do async in there, instead of in the actions themselves, and in Middleware?
    • First and most important, the creators don't have access to the store, as middleware does. That means you can't dispatch new contingent actions, can't read from the store to compose your async, etc.
    • So, keep complexity in a place that's complex of necessity, and keep everything else simple. The creators can then be simple, relatively pure functions that are easy to test.

Here is how I solved it for myself. Below is an Entity example with default value for MySQL. However, this also requires the setup of a constructor in your entity, and for you to set the default value there.

Entity\Example:
  type: entity
  table: example
  fields:
    id:
      type: integer
      id: true
      generator:
        strategy: AUTO
    label:
      type: string
      columnDefinition: varchar(255) NOT NULL DEFAULT 'default_value' COMMENT 'This is column comment'

#An example for counting matched groups

res = re.match(pattern, search_str)
print(len(res.groups())) # len = 4  
print (res.group(1) ) #My
print (res.group(2) ) #11
print (res.group(3) ) #Char
print (res.group(4) ) #String

I have a simple solution on handling home button press. Here is my code, it can be useful:

public class LifeCycleActivity extends Activity {


boolean activitySwitchFlag = false;

@Override
public boolean onKeyDown(int keyCode, KeyEvent event) 
{
    if(keyCode == KeyEvent.KEYCODE_BACK)
    {
        activitySwitchFlag = true;
        // activity switch stuff..
        return true;
    }
    return false;
}

/** Called when the activity is first created. */
@Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.main);
}

@Override 
public void onPause(){
    super.onPause();
    Log.v("TAG", "onPause" );
    if(activitySwitchFlag)
        Log.v("TAG", "activity switch");
    else
        Log.v("TAG", "home button");
    activitySwitchFlag = false;
}

public void gotoNext(View view){
    activitySwitchFlag = true;
    startActivity(new Intent(LifeCycleActivity.this, NextActivity.class));
}

}

As a summary, put a boolean in the activity, when activity switch occurs(startactivity event), set the variable and in onpause event check this variable..

If you just run jmap -histo:live or jmap -histo, it outputs the contents on the console!

I could solve this installing Newtonsoft Json in the web project with nugget packages

In C++20 you'll be able to use std::format to do this:

unsigned char a = -58;
std::cout << std::format("{:b}", a);

Output:

11000110

In the meantime you can use the {fmt} library, std::format is based on. {fmt} also provides the print function that makes this even easier and more efficient (godbolt):

unsigned char a = -58;
fmt::print("{:b}", a);

Disclaimer: I'm the author of {fmt} and C++20 std::format.

Here is a quickly hacked up version of this using SVG I just did. Works well for me on my iPhone. Also works in a desktop browser using normal mouse events.

Answer from italo is very good! However let me refine it a little:

function isEllipsisActive(e) {
   var tolerance = 2; // In px. Depends on the font you are using
   return e.offsetWidth + tolerance < e.scrollWidth;
}

Cross browser compatibility

If, in fact, you try the above code and use console.log to print out the values of e.offsetWidth and e.scrollWidth, you will notice, on IE, that, even when you have no text truncation, a value difference of 1px or 2px is experienced.

So, depending on the font size you use, allow a certain tolerance!

You need to spend a little more time on some fundamentals of object-oriented programming.

This sounds harsh, but it's important.

• Your class definition is incorrect -- although the syntax happens to be acceptable. The definition is simply wrong.

• Your use of the class to create an object is entirely missing.

• Your use of a class to do a calculation is inappropriate. This kind of thing can be done, but it requires the advanced concept of a @staticmehod.

Since your example code is wrong in so many ways, you can't get a tidy "fix this" answer. There are too many things to fix.

You'll need to look at better examples of class definitions. It's not clear what source material you're using to learn from, but whatever book you're reading is either wrong or incomplete.

Please discard whatever book or source you're using and find a better book. Seriously. They've mislead you on how a class definition looks and how it's used.

You might want to look at http://homepage.mac.com/s_lott/books/nonprog/htmlchunks/pt11.html for a better introduction to classes, objects and Python.

You can use this one 24H, seconds are optional

Faced with same issue

ImportError: No module named numpy

So, in our case (we are use PIP and python 2.7) the solution was SPLIT pip install commands :

From

RUN pip install numpy scipy pandas sklearn

TO

RUN pip install numpy scipy
RUN pip install pandas sklearn

Solution found here : https://github.com/pandas-dev/pandas/issues/25193, it's related latest update of pandas to v0.24.0

Updating lines in place in a file is not supported on most file system (a line in a file is just some data that ends with newline, the next line start just after that).

As I see it you have two options:

1. Have your data generating loops be generators, this way they won't consume a lot of memory - you'll get data for each row "just in time"
2. Use a database (sqlite?) and update the rows there. When you're done - export to CSV

Small example for the first method:

from itertools import islice, izip, count
print list(islice(izip(count(1), count(2), count(3)), 10))

This will print

[(1, 2, 3), (2, 3, 4), (3, 4, 5), (4, 5, 6), (5, 6, 7), (6, 7, 8), (7, 8, 9), (8, 9, 10), (9, 10, 11), (10, 11, 12)]

even though count generate an infinite sequence of numbers

Here is better resolution

public static Bitmap drawableToBitmap (Drawable drawable) {
    if (drawable instanceof BitmapDrawable) {
        return ((BitmapDrawable)drawable).getBitmap();
    }

    Bitmap bitmap = Bitmap.createBitmap(drawable.getIntrinsicWidth(), drawable.getIntrinsicHeight(), Config.ARGB_8888);
    Canvas canvas = new Canvas(bitmap); 
    drawable.setBounds(0, 0, canvas.getWidth(), canvas.getHeight());
    drawable.draw(canvas);

    return bitmap;
}

public static InputStream bitmapToInputStream(Bitmap bitmap) {
    int size = bitmap.getHeight() * bitmap.getRowBytes();
    ByteBuffer buffer = ByteBuffer.allocate(size);
    bitmap.copyPixelsToBuffer(buffer);
    return new ByteArrayInputStream(buffer.array());
}

Code from How to read drawable bits as InputStream

One thing to note:

The .FRM file has your table structure in it, and is specific to your MySQL version.

The .MYD file is NOT specific to version, at least not minor versions.

The .MYI file is specific, but can be left out and regenerated with REPAIR TABLE like the other answers say.

The point of this answer is to let you know that if you have a schema dump of your tables, then you can use that to generate the table structure, then replace those .MYD files with your backups, delete the MYI files, and repair them all. This way you can restore your backups to another MySQL version, or move your database altogether without using mysqldump. I've found this super helpful when moving large databases.

Another variation: Define two functions in the trait, a protected one that performs the actual task, and a public one which in turn calls the protected one.

This just saves classes from having to mess with the 'use' statement if they want to override the function, since they can still call the protected function internally.

trait A {
    protected function traitcalc($v) {
        return $v+1;
    }

    function calc($v) {
        return $this->traitcalc($v);
    }
}

class MyClass {
    use A;

    function calc($v) {
        $v++;
        return $this->traitcalc($v);
    }
}

class MyOtherClass {
    use A;
}


print (new MyClass())->calc(2); // will print 4

print (new MyOtherClass())->calc(2); // will print 3

These functions, based on the above, seem to work well for getting characters from the keyboard (blocking and non-blocking):

import termios, fcntl, sys, os

def get_char_keyboard():
  fd = sys.stdin.fileno()

  oldterm = termios.tcgetattr(fd)
  newattr = termios.tcgetattr(fd)
  newattr[3] = newattr[3] & ~termios.ICANON & ~termios.ECHO
  termios.tcsetattr(fd, termios.TCSANOW, newattr)

  c = None
  try:
    c = sys.stdin.read(1)
  except IOError: pass

  termios.tcsetattr(fd, termios.TCSAFLUSH, oldterm)

  return c

def get_char_keyboard_nonblock():
  fd = sys.stdin.fileno()

  oldterm = termios.tcgetattr(fd)
  newattr = termios.tcgetattr(fd)
  newattr[3] = newattr[3] & ~termios.ICANON & ~termios.ECHO
  termios.tcsetattr(fd, termios.TCSANOW, newattr)

  oldflags = fcntl.fcntl(fd, fcntl.F_GETFL)
  fcntl.fcntl(fd, fcntl.F_SETFL, oldflags | os.O_NONBLOCK)

  c = None

  try:
    c = sys.stdin.read(1)
  except IOError: pass

  termios.tcsetattr(fd, termios.TCSAFLUSH, oldterm)
  fcntl.fcntl(fd, fcntl.F_SETFL, oldflags)

  return c

On wildfly 8 and later, go to /bin/standalone.conf and put your JAVA_OPTS there, with all you need.

I know this question was asked a while ago, but in case useful, the here package is really helpful for not having to reference specific file paths and making code more portable. It will automatically define your working directory as the one that your .Rproj file resides in, so the following will often suffice without having to define the file path to your working directory:

library(here)

if (!dir.exists(here(outputDir))) {dir.create(here(outputDir))}

This is what I did for my app. If you take a look at the following classes in the bootstrap.css file .modal-dialog has a default padding of 10px and @media screen and (min-width: 768px) .modal-dialog has a top padding set to 30px. So in my custom css file I set my top padding to be 15% for all screens without specifying a media screen width. Hope this helps.

.modal-dialog {
  padding-top: 15%;
}

You can use this text-underline-position: under

See here for more detail: https://css-tricks.com/almanac/properties/t/text-underline-position/

See also browser compatibility.

The columns parameter accepts a collection of column names. You're passing a list containing a dataframe with two rows:

>>> [df[1:]]
[  viz  a1_count  a1_mean  a1_std
1   n         0      NaN     NaN
2   n         2       51      50]
>>> df.as_matrix(columns=[df[1:]])
array([[ nan,  nan],
       [ nan,  nan],
       [ nan,  nan]])

Instead, pass the column names you want:

>>> df.columns[1:]
Index(['a1_count', 'a1_mean', 'a1_std'], dtype='object')
>>> df.as_matrix(columns=df.columns[1:])
array([[  3.      ,   2.      ,   0.816497],
       [  0.      ,        nan,        nan],
       [  2.      ,  51.      ,  50.      ]])

Any Activity that restarts has its onResume() method executed first.

To use this method, do this:

@Override
public void onResume(){
    super.onResume();
    // put your code here...

}

dir(sys) says no. len(sys.argv) works, but in Python it is better to ask for forgiveness than permission, so

#!/usr/bin/python
import sys
try:
    in_file = open(sys.argv[1], "r")
except:
    sys.exit("ERROR. Can't read supplied filename.")
text = in_file.read()
print(text)
in_file.close()

works fine and is shorter.

If you're going to exit anyway, this would be better:

#!/usr/bin/python
import sys
text = open(sys.argv[1], "r").read()
print(text)

I'm using print() so it works in 2.7 as well as Python 3.

You can just do

System.out.print("String");

Instead

System.out.println("String");

Center in container

The code below does the same thing as centering in the Interface Builder.

override func viewDidLoad() {
    super.viewDidLoad()

    // set up the view
    let myView = UIView()
    myView.backgroundColor = UIColor.blue
    myView.translatesAutoresizingMaskIntoConstraints = false
    view.addSubview(myView)

    // Add code for one of the constraint methods below
    // ...
}

Method 1: Anchor Style

myView.centerXAnchor.constraint(equalTo: view.centerXAnchor).isActive = true
myView.centerYAnchor.constraint(equalTo: view.centerYAnchor).isActive = true

Method 2: NSLayoutConstraint Style

NSLayoutConstraint(item: myView, attribute: NSLayoutConstraint.Attribute.centerX, relatedBy: NSLayoutConstraint.Relation.equal, toItem: view, attribute: NSLayoutConstraint.Attribute.centerX, multiplier: 1, constant: 0).isActive = true
NSLayoutConstraint(item: myView, attribute: NSLayoutConstraint.Attribute.centerY, relatedBy: NSLayoutConstraint.Relation.equal, toItem: view, attribute: NSLayoutConstraint.Attribute.centerY, multiplier: 1, constant: 0).isActive = true

Notes

• Anchor style is the preferred method over NSLayoutConstraint Style, however it is only available from iOS 9, so if you are supporting iOS 8 then you should still use NSLayoutConstraint Style.
• You will also need to add length and width constraints.
• My full answer is here.

Spark 2.2+

Spark 2.2 introduces typedLit to support Seq, Map, and Tuples (SPARK-19254) and following calls should be supported (Scala):

import org.apache.spark.sql.functions.typedLit

df.withColumn("some_array", typedLit(Seq(1, 2, 3)))
df.withColumn("some_struct", typedLit(("foo", 1, 0.3)))
df.withColumn("some_map", typedLit(Map("key1" -> 1, "key2" -> 2)))

Spark 1.3+ (lit), 1.4+ (array, struct), 2.0+ (map):

The second argument for DataFrame.withColumn should be a Column so you have to use a literal:

from pyspark.sql.functions import lit

df.withColumn('new_column', lit(10))

If you need complex columns you can build these using blocks like array:

from pyspark.sql.functions import array, create_map, struct

df.withColumn("some_array", array(lit(1), lit(2), lit(3)))
df.withColumn("some_struct", struct(lit("foo"), lit(1), lit(.3)))
df.withColumn("some_map", create_map(lit("key1"), lit(1), lit("key2"), lit(2)))

Exactly the same methods can be used in Scala.

import org.apache.spark.sql.functions.{array, lit, map, struct}

df.withColumn("new_column", lit(10))
df.withColumn("map", map(lit("key1"), lit(1), lit("key2"), lit(2)))

To provide names for structs use either alias on each field:

df.withColumn(
    "some_struct",
    struct(lit("foo").alias("x"), lit(1).alias("y"), lit(0.3).alias("z"))
 )

or cast on the whole object

df.withColumn(
    "some_struct", 
    struct(lit("foo"), lit(1), lit(0.3)).cast("struct<x: string, y: integer, z: double>")
 )

It is also possible, although slower, to use an UDF.

Note:

The same constructs can be used to pass constant arguments to UDFs or SQL functions.

Here is code for getting value return from Store procedure

Stored procedure:

alter proc [dbo].[UserlogincheckMVC]    
@username nvarchar(max),    
@password nvarchar(max)
as    
begin    
    if exists(select Username from Adminlogin where Username =@username and Password=@password)    
        begin        
            return 1  
        end    
    else    
        begin     
            return 0  
        end    
end 

Code:

var parameters = new DynamicParameters();
string pass = EncrytDecry.Encrypt(objUL.Password);
conx.Open();
parameters.Add("@username", objUL.Username);
parameters.Add("@password", pass);
parameters.Add("@RESULT", dbType: DbType.Int32, direction: ParameterDirection.ReturnValue);
var RS = conx.Execute("UserlogincheckMVC", parameters, null, null, commandType: CommandType.StoredProcedure);
int result = parameters.Get<int>("@RESULT");

I think you have to draw the listitems yourself to achieve this.

Here's a post with the same kind of question.

I wrote a small tool that does just that. Code is available on github.

To dump the results of one (or more) SQL queries to one (or more) CSV files:

java -jar sql_dumper.jar /path/sql/files/ /path/out/ user pass jdbcString

Cheers.

The two queries express the same question. Apparently the query optimizer chooses two different execution plans. My guess would be that the distinct approach is executed like:

• Copy all business_key values to a temporary table
• Sort the temporary table
• Scan the temporary table, returning each item that is different from the one before it

The group by could be executed like:

• Scan the full table, storing each value of business key in a hashtable
• Return the keys of the hashtable

The first method optimizes for memory usage: it would still perform reasonably well when part of the temporary table has to be swapped out. The second method optimizes for speed, but potentially requires a large amount of memory if there are a lot of different keys.

Since you either have enough memory or few different keys, the second method outperforms the first. It's not unusual to see performance differences of 10x or even 100x between two execution plans.

You should set async = false in head. Use post/get instead of ajax.

jQuery.ajaxSetup({ async: false });

    $.post({
        url: 'api.php',
        data: 'id1=' + q + '',
        dataType: 'json',
        success: function (data) {

            id = data[0];
            vname = data[1];

        }
    });

You can use paste:

paste file1.txt file2.txt > fileresults.txt

You can also use template matching to detect shapes inside an image.

Using pure bash :

$ cat file.txt
US/Central - 10:26 PM (CST)
$ while read a b time x; do [[ $b == - ]] && echo $time; done < file.txt

another solution with bash regex :

$ [[ "US/Central - 10:26 PM (CST)" =~ -[[:space:]]*([0-9]{2}:[0-9]{2}) ]] &&
    echo ${BASH_REMATCH[1]}

another solution using grep and look-around advanced regex :

$ echo "US/Central - 10:26 PM (CST)" | grep -oP "\-\s+\K\d{2}:\d{2}"

another solution using sed :

$ echo "US/Central - 10:26 PM (CST)" |
    sed 's/.*\- *\([0-9]\{2\}:[0-9]\{2\}\).*/\1/'

another solution using perl :

$ echo "US/Central - 10:26 PM (CST)" |
    perl -lne 'print $& if /\-\s+\K\d{2}:\d{2}/'

and last one using awk :

$ echo "US/Central - 10:26 PM (CST)" |
    awk '{for (i=0; i<=NF; i++){if ($i == "-"){print $(i+1);exit}}}'

The While statement will not execute until after form1 is closed - as it is outside the main message loop.

Remove it and change the first bit of code to:

private void button1_Click_1(object sender, EventArgs e)  
{  
    if (richTextBox1.Text != null)  
    {  
        this.Visible=false;
        Form2 form2 = new Form2();
        form2.show();
    }  
    else MessageBox.Show("Insert Attributes First !");  

}

This is not the best way to achieve what you are looking to do though. Instead consider the Wizard design pattern.

Alternatively you could implement a custom ApplicationContext that handles the lifetime of both forms. An example to implement a splash screen is here, which should set you on the right path.

http://www.codeproject.com/KB/cs/applicationcontextsplash.aspx?display=Print

git diff --shortstat

gives you just the number of lines changed and added. This only works with unstaged changes. To compare against a branch:

git diff --shortstat some-branch

If Java is installed on the target machine, there is no need to create an .exe file. A .jar file should be sufficient.

Please try to this one

public void Method(Datetime time)
{
    time.toString("yyyy-MM-dd'T'HH:mm:ss"));
}
