Just a wild guess: (not much to go on) but I have had similar problems when, for example, I was using the IIS rewrite module on my local machine (and it worked fine), but when I uploaded to a host that did not have that add-on module installed, I would get a 500 error with very little to go on - sounds similar. It drove me crazy trying to find it.

So make sure whatever options/addons that you might have and be using locally in IIS are also installed on the host.

Similarly, make sure you understand everything that is being referenced/used in your web.config - that is likely the problem area.

You may need to config the CORS at Spring Boot side. Please add below class in your Project.

import javax.servlet.Filter;
import javax.servlet.FilterChain;
import javax.servlet.ServletRequest;
import javax.servlet.ServletResponse;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;

import org.springframework.context.annotation.Configuration;
import org.springframework.web.servlet.config.annotation.CorsRegistry;
import org.springframework.web.servlet.config.annotation.EnableWebMvc;
import org.springframework.web.servlet.config.annotation.ResourceHandlerRegistry;
import org.springframework.web.servlet.config.annotation.WebMvcConfigurer;

@Configuration
@EnableWebMvc
public class WebConfig implements Filter,WebMvcConfigurer {



    @Override
    public void addCorsMappings(CorsRegistry registry) {
        registry.addMapping("/**");
    }

    @Override
    public void doFilter(ServletRequest req, ServletResponse res, FilterChain chain) {
      HttpServletResponse response = (HttpServletResponse) res;
      HttpServletRequest request = (HttpServletRequest) req;
      System.out.println("WebConfig; "+request.getRequestURI());
      response.setHeader("Access-Control-Allow-Origin", "*");
      response.setHeader("Access-Control-Allow-Methods", "POST, PUT, GET, OPTIONS, DELETE");
      response.setHeader("Access-Control-Allow-Headers", "Content-Type, Access-Control-Allow-Headers, Authorization, X-Requested-With,observe");
      response.setHeader("Access-Control-Max-Age", "3600");
      response.setHeader("Access-Control-Allow-Credentials", "true");
      response.setHeader("Access-Control-Expose-Headers", "Authorization");
      response.addHeader("Access-Control-Expose-Headers", "responseType");
      response.addHeader("Access-Control-Expose-Headers", "observe");
      System.out.println("Request Method: "+request.getMethod());
      if (!(request.getMethod().equalsIgnoreCase("OPTIONS"))) {
          try {
              chain.doFilter(req, res);
          } catch(Exception e) {
              e.printStackTrace();
          }
      } else {
          System.out.println("Pre-flight");
          response.setHeader("Access-Control-Allow-Origin", "*");
          response.setHeader("Access-Control-Allow-Methods", "POST,GET,DELETE,PUT");
          response.setHeader("Access-Control-Max-Age", "3600");
          response.setHeader("Access-Control-Allow-Headers", "Access-Control-Expose-Headers"+"Authorization, content-type," +
          "USERID"+"ROLE"+
                  "access-control-request-headers,access-control-request-method,accept,origin,authorization,x-requested-with,responseType,observe");
          response.setStatus(HttpServletResponse.SC_OK);
      }

    }

}

UPDATE:

To append Token to each request you can create one Interceptor as below.

import { Injectable } from '@angular/core';
import { HttpEvent, HttpHandler, HttpInterceptor, HttpRequest } from '@angular/common/http';
import { Observable } from 'rxjs';

@Injectable()
export class AuthInterceptor implements HttpInterceptor {

  intercept(req: HttpRequest<any>, next: HttpHandler): Observable<HttpEvent<any>> {
    const token = window.localStorage.getItem('tokenKey'); // you probably want to store it in localStorage or something


    if (!token) {
      return next.handle(req);
    }

    const req1 = req.clone({
      headers: req.headers.set('Authorization', `${token}`),
    });

    return next.handle(req1);
  }

}

Example

Have you tried not setting the responseType and just type casting the response?

This is what worked for me:

/**
 * Client for consuming recordings HTTP API endpoint.
 */
@Injectable({
  providedIn: 'root'
})
export class DownloadUrlClientService {
  private _log = Log.create('DownloadUrlClientService');


  constructor(
    private _http: HttpClient,
  ) {}

  private async _getUrl(url: string): Promise<string> {
    const httpOptions = {headers: new HttpHeaders({'auth': 'false'})};
    // const httpOptions = {headers: new HttpHeaders({'auth': 'false'}), responseType: 'text'};
    const res = await (this._http.get(url, httpOptions) as Observable<string>).toPromise();
    // const res = await (this._http.get(url, httpOptions)).toPromise();
    return res;
  }
}

There are two reasons for this error

1) In the array of import if you imported HttpModule twice

2) If you haven't import:

import { HttpModule, JsonpModule } from '@angular/http'; 

If you want then run:

npm install @angular/http

For me I had this issue when I first installed Docker and ran

docker run hello-world

I got an authentication required error when I ran

curl https://registry-1.docker.io/v2/ && echo Works

All I needed to do was to restart my MacOS and then run the command again, it just started pulling the image and i got the message

Hello from Docker!
This message shows that your installation appears to be working correctly.

It could be done in Bootstrap 4 using the responsive grid columns. One column for the sidebar and one for the main content.

Bootstrap 4 Sidebar switch to Top Navbar on mobile

<div class="container-fluid h-100">
    <div class="row h-100">
        <aside class="col-12 col-md-2 p-0 bg-dark">
            <nav class="navbar navbar-expand navbar-dark bg-dark flex-md-column flex-row align-items-start">
                <div class="collapse navbar-collapse">

        <main class="col">
            ..
        </main>

Alternate sidebar to top
Fixed sidebar to top

For the reverse (Top Navbar that becomes a Sidebar), can be done like this example

The following worked for me after hours of trying

      $http.post("http://localhost:8080/yourresource", parameter, {headers: 
      {'Content-Type': 'application/json', 'Access-Control-Allow-Origin': '*' } }).

However following code did not work, I am unclear as to why, hopefully someone can improve this answer.

          $http({   method: 'POST', url: "http://localhost:8080/yourresource", 
                    parameter, 
                    headers: {'Content-Type': 'application/json', 
                              'Access-Control-Allow-Origin': '*',
                              'Access-Control-Allow-Methods': 'POST'} 
                })

HttpClient.get() applies res.json() automatically and returns Observable<HttpResponse<string>>. You no longer need to call this function yourself.

Update December 2019 ionic - 4.7.1

<manifest xmlns:tools=“http://schemas.android.com/tools”>

<application android:usesCleartextTraffic=“true” tools:targetApi=“28”>

Please add above content in android manifest .xml file

Previous Versions of ionic

1. Make sure you have the following in your config.xml in Ionic Project:

   <edit-config file="app/src/main/AndroidManifest.xml" mode="merge" target="/manifest/application" xmlns:android="http://schemas.android.com/apk/res/android">
               <application android:networkSecurityConfig="@xml/network_security_config" />
               <application android:usesCleartextTraffic="true" />
           </edit-config>
   

2. Run ionic Cordova build android. It creates Android folder under Platforms

3. Open Android Studio and open the Android folder present in our project project-platforms-android. Leave it for few minutes so that it builds the gradle

4. After gradle build is finished we get some errors for including minSdVersion in manifest.xml. Now what we do is just remove <uses-sdk android:minSdkVersion="19" /> from manifest.xml.

   Make sure its removed from both the locations:

   1. app → manifests → AndroidManifest.xml.
   2. CordovaLib → manifests → AndroidManifest.xml.

   Now try to build the gradle again and now it builds successfully

5. Make sure you have the following in Application tag in App → manifest → Androidmanifest.xml:

   <application
   android:networkSecurityConfig="@xml/network_security_config"  android:usesCleartextTraffic="true" >
   

6. Open network_security_config (app → res → xml → network_security_config.xml).

   Add the following code:

   <?xml version="1.0" encoding="utf-8"?>
   <network-security-config>
       <domain-config cleartextTrafficPermitted="true">
           <domain includeSubdomains="true">xxx.yyyy.com</domain>
       </domain-config>
   </network-security-config>
   

Here xxx.yyyy.com is the link of your HTTP API. Make sure you don't include any Http before the URL.

Note: Now build the app using Android Studio (Build -- Build Bundle's/APK -- Build APK) and now you can use that App and it works fine in Android Pie. If you try to build app using ionic Cordova build android it overrides all these settings so make sure you use Android Studio to build the Project.

If you have any older versions of app installed, Uninstall them and give a try or else you will be left with some error:

App not Installed

I struggled with this for a long time. I am using Angular 6 and I found that

let headers = new HttpHeaders();
headers = headers.append('key', 'value');

did not work. But what did work was

let headers = new HttpHeaders().append('key', 'value');

did, which makes sense when you realize they are immutable. So having created a header you can't add to it. I haven't tried it, but I suspect

let headers = new HttpHeaders();
let headers1 = headers.append('key', 'value');

would work too.

I was trying to use Feign, while I encounter same issue, As I understood HTTP message converter will help but wanted to understand how to achieve this.

@FeignClient(name = "mobilesearch", url = "${mobile.search.uri}" ,
        fallbackFactory = MobileSearchFallbackFactory.class,
        configuration = MobileSearchFeignConfig.class)
public interface MobileSearchClient {

    @RequestMapping(method = RequestMethod.GET)
    List<MobileSearchResponse> getPhones();
}

You have to use Customer Configuration for the decoder, MobileSearchFeignConfig,

public class MobileSearchFeignConfig {

    @Bean
    Logger.Level feignLoggerLevel() {
        return Logger.Level.FULL;
    }


    @Bean
    public Decoder feignDecoder() {
        return new ResponseEntityDecoder(new SpringDecoder(feignHttpMessageConverter()));
    }

    public ObjectFactory<HttpMessageConverters> feignHttpMessageConverter() {
        final HttpMessageConverters httpMessageConverters = new HttpMessageConverters(new MappingJackson2HttpMessageConverter());
        return new ObjectFactory<HttpMessageConverters>() {
            @Override
            public HttpMessageConverters getObject() throws BeansException {
                return httpMessageConverters;
            }
        };
    }

    public class MappingJackson2HttpMessageConverter extends org.springframework.http.converter.json.MappingJackson2HttpMessageConverter {
        MappingJackson2HttpMessageConverter() {
            List<MediaType> mediaTypes = new ArrayList<>();
            mediaTypes.add(MediaType.valueOf(MediaType.TEXT_HTML_VALUE + ";charset=UTF-8"));
            setSupportedMediaTypes(mediaTypes);
        }
    }

}

Kotlin Coroutines (Clear & Concise)

AsyncTask is really clunky. Coroutines are a cleaner alternative (just sprinkle a couple of keywords and your sync code becomes async).

// Step 1: add `suspend` to your fun
suspend fun roomFun(...): Int
suspend fun notRoomFun(...) = withContext(Dispatchers.IO) { ... }

// Step 2: launch from coroutine scope
private fun myFun() {
    lifecycleScope.launch { // coroutine on Main
        val queryResult = roomFun(...) // coroutine on IO
        doStuff() // ...back on Main
    }
}

Dependencies (adds coroutine scopes for arch components):

// lifecycleScope:
implementation 'androidx.lifecycle:lifecycle-runtime-ktx:2.2.0-alpha04'

// viewModelScope:
implementation 'androidx.lifecycle:lifecycle-viewmodel-ktx:2.2.0-alpha04'

-- Updates:
08-May-2019: Room 2.1 now supports suspend
13-Sep-2019: Updated to use Architecture components scope

I had the same problem, then I did this two steps:

• Enable "Allow less secure apps" on your google account security policy.
• Restart your local servers.

Template/HTML File (component.ts)

<select>
 <option *ngFor="let v of values" [value]="v" (ngModelChange)="onChange($event)">  
    {{v.name}}
  </option>
</select>

Typescript File (component.ts)

values = [
  { id: 3432, name: "Recent" },
  { id: 3442, name: "Most Popular" },
  { id: 3352, name: "Rating" }
];

onChange(cityEvent){
    console.log(cityEvent); // It will display the select city data
}

(ngModelChange) is the @Output of the ngModel directive. It fires when the model changes. You cannot use this event without the ngModel directive

When pip tells you that you already have protobuf, but PyCharm (or other) tells you that you don't have it, it means that pip and PyCharm are using a different Python interpreter. This is a very common issue, especially on a Mac, with no standard Python package management.

The best way to completely eliminate such issues is using a virtualenv per Python project, which is essentially a directory of Python packages and environment variable settings to isolate the Python environment of the project from everything else.

Create a virtualenv for your project like this:

cd project
virtualenv --distribute virtualenv -p /path/to/python/executable

This creates a directory called virtualenv inside your project. (Make sure to configure your VCS (for example Git) to ignore this directory.)

To install packages in this virtualenv, you need to activate the environment variable settings:

. virtualenv/bin/activate

Verify that pip will use the right Python executable inside the virtualenv, by running pip -V. It should tell you the Python library path used, which should be inside the virtualenv.

Now you can use pip to install protobuf as you did.

And finally, you need to make PyCharm use this virtualenv instead of the system libraries. Somewhere in the project settings you can configure an interpreter for the project, select the Python executable inside the virtualenv.

This is what worked for me. Issue is earlier I didn't set Content Type(header) when I used exchange method.

MultiValueMap<String, String> map = new LinkedMultiValueMap<String, String>();
map.add("param1", "123");
map.add("param2", "456");
map.add("param3", "789");
map.add("param4", "123");
map.add("param5", "456");

HttpHeaders headers = new HttpHeaders();
headers.setContentType(MediaType.APPLICATION_FORM_URLENCODED);

final HttpEntity<MultiValueMap<String, String>> entity = new HttpEntity<MultiValueMap<String, String>>(map ,
        headers);
JSONObject jsonObject = null;

try {
    RestTemplate restTemplate = new RestTemplate();
    ResponseEntity<String> responseEntity = restTemplate.exchange(
            "https://url", HttpMethod.POST, entity,
            String.class);

    if (responseEntity.getStatusCode() == HttpStatus.CREATED) {
        try {
            jsonObject = new JSONObject(responseEntity.getBody());
        } catch (JSONException e) {
            throw new RuntimeException("JSONException occurred");
        }
    }
  } catch (final HttpClientErrorException httpClientErrorException) {
        throw new ExternalCallBadRequestException();
  } catch (HttpServerErrorException httpServerErrorException) {
        throw new ExternalCallServerErrorException(httpServerErrorException);
  } catch (Exception exception) {
        throw new ExternalCallServerErrorException(exception);
    } 

ExternalCallBadRequestException and ExternalCallServerErrorException are the custom exceptions here.

Note: Remember HttpClientErrorException is thrown when a 4xx error is received. So if the request you send is wrong either setting header or sending wrong data, you could receive this exception.

Actually there are many reasons for this issue. Mine was because of Invalid token passed. I was passing same token generated from one app and using same token in another app. Once token updated , it work for me.

Kotlin solution

...
http.cors().configurationSource {
  CorsConfiguration().applyPermitDefaultValues()
}
...

You simply need to add that line legend: { display: false }

Building on the other answers, I suggest this code, which does not have any outside dependencies:

[TestClass]
public class MyTestClass
{
    [TestMethod]
    public async Task MyTestMethod()
    {
        var httpClient = new HttpClient(new MockHttpMessageHandler());

        var content = await httpClient.GetStringAsync("http://some.fake.url");

        Assert.AreEqual("Content as string", content);
    }
}

public class MockHttpMessageHandler : HttpMessageHandler
{
    protected override async Task<HttpResponseMessage> SendAsync(
        HttpRequestMessage request,
        CancellationToken cancellationToken)
    {
        var responseMessage = new HttpResponseMessage(HttpStatusCode.OK)
        {
            Content = new StringContent("Content as string")
        };

        return await Task.FromResult(responseMessage);
    }
}

When your HTMLElement doesn't have an id, name or class to call,

then use

<input type="text" (click)="selectedInput($event)">

selectedInput(event: MouseEvent) {
   log(event.srcElement) // HTMInputLElement
}

If you need to download a huge file from the server's file system, then ByteArrayResource can take all Java heap space. In that case, you can use FileSystemResource

My error was because of writing it this way:

props.allinfo.map((stuff, i)=>{
  return (<p key={i}> I am {stuff} </p>)
})

instead of:

props.allinfo.map((stuff, i)=>{
  return (<p key={i}> I am {stuff.name} </p>)
})

It meant I was trying to render object instead of the value within it.

edit: this is for react not native.

From Apple documentation

If you’re developing a new app, you should use HTTPS exclusively. If you have an existing app, you should use HTTPS as much as you can right now, and create a plan for migrating the rest of your app as soon as possible. In addition, your communication through higher-level APIs needs to be encrypted using TLS version 1.2 with forward secrecy. If you try to make a connection that doesn't follow this requirement, an error is thrown. If your app needs to make a request to an insecure domain, you have to specify this domain in your app's Info.plist file.

To Bypass App Transport Security:

<key>NSAppTransportSecurity</key>
<dict>
  <key>NSExceptionDomains</key>
  <dict>
    <key>yourserver.com</key>
    <dict>
      <!--Include to allow subdomains-->
      <key>NSIncludesSubdomains</key>
      <true/>
      <!--Include to allow HTTP requests-->
      <key>NSTemporaryExceptionAllowsInsecureHTTPLoads</key>
      <true/>
      <!--Include to specify minimum TLS version-->
      <key>NSTemporaryExceptionMinimumTLSVersion</key>
      <string>TLSv1.1</string>
    </dict>
  </dict>
</dict>

To allow all insecure domains

<key>NSAppTransportSecurity</key>
<dict>
  <!--Include to allow all connections (DANGER)-->
  <key>NSAllowsArbitraryLoads</key>
  <true/>
</dict>

Add a "User-Agent" header to your request.

Some servers attempt to block spidering programs and scrapers from accessing their server because, in earlier days, requests did not send a user agent header.

You can either try to set a custom user agent value or use some value that identifies a Browser like "Mozilla/5.0 Firefox/26.0"

RestTemplate restTemplate = new RestTemplate();
HttpHeaders headers = new HttpHeaders();

headers.setAccept(Arrays.asList(MediaType.APPLICATION_JSON));
headers.setContentType(MediaType.APPLICATION_JSON);
headers.add("user-agent", "Mozilla/5.0 Firefox/26.0");
headers.set("user-key", "your-password-123"); // optional - in case you auth in headers
HttpEntity<String> entity = new HttpEntity<String>("parameters", headers);
ResponseEntity<Game[]> respEntity = restTemplate.exchange(url, HttpMethod.GET, entity, Game[].class);

logger.info(respEntity.toString());

As Sotirios Delimanolis already pointed out in the comments, there are two options:

Return ResponseEntity with error message

Change your method like this:

@RequestMapping(method = RequestMethod.GET)
public ResponseEntity getUser(@RequestHeader(value="Access-key") String accessKey,
                              @RequestHeader(value="Secret-key") String secretKey) {
    try {
        // see note 1
        return ResponseEntity
            .status(HttpStatus.CREATED)                 
            .body(this.userService.chkCredentials(accessKey, secretKey, timestamp));
    }
    catch(ChekingCredentialsFailedException e) {
        e.printStackTrace(); // see note 2
        return ResponseEntity
            .status(HttpStatus.FORBIDDEN)
            .body("Error Message");
    }
}

Note 1: You don't have to use the ResponseEntity builder but I find it helps with keeping the code readable. It also helps remembering, which data a response for a specific HTTP status code should include. For example, a response with the status code 201 should contain a link to the newly created resource in the Location header (see Status Code Definitions). This is why Spring offers the convenient build method ResponseEntity.created(URI).

Note 2: Don't use printStackTrace(), use a logger instead.

Provide an @ExceptionHandler

Remove the try-catch block from your method and let it throw the exception. Then create another method in a class annotated with @ControllerAdvice like this:

@ControllerAdvice
public class ExceptionHandlerAdvice {

    @ExceptionHandler(ChekingCredentialsFailedException.class)
    public ResponseEntity handleException(ChekingCredentialsFailedException e) {
        // log exception
        return ResponseEntity
                .status(HttpStatus.FORBIDDEN)
                .body("Error Message");
    }        
}

Note that methods which are annotated with @ExceptionHandler are allowed to have very flexible signatures. See the Javadoc for details.

a combination of several answers found in my attempt to not use 3rd party frameworks like Alamofire.

    let body: [String: Any] = ["provider": "Google", "email": "[email protected]"]
    let api_url = "https://erics.es/p/u"
    let url = URL(string: api_url)!
    var request = URLRequest(url: url)

    do {
        let jsonData = try JSONSerialization.data(withJSONObject: body, options: .prettyPrinted)
        request.httpBody = jsonData
    } catch let e {
        print(e)
    }

    request.httpMethod = HTTPMethod.post.rawValue
    request.addValue("application/json", forHTTPHeaderField: "Content-Type")

    let task = URLSession.shared.dataTask(with: request) { data, response, error in
        guard let data = data, error == nil else {
            print(error?.localizedDescription ?? "No data")
            return
        }
        let responseJSON = try? JSONSerialization.jsonObject(with: data, options: [])
        if let responseJSON = responseJSON as? [String: Any] {
            print(responseJSON)
        }
    }

    task.resume()

All you need is to authorize debug mode.
1. make sure your Device is connected to your PC.
2. Allow authorized for debug mode via Android-Studio by going to
Run -> Attach debugger to Android process
than you will see the pop up window for allow debug mode in your Device,
press OK. done.
i hope it help to someone.

It might be that you are forgetting to specify the settings which was the case with me.

Try:

mvn clean install -s settings_file.xml

BATCH LOAD - OK, so after having my previous reply deleted for just using links I have updated with the code I managed to get working. Appreciate anyone to simplify / correct / refine / put in function etc as I'm still learning this stuff, but I got batch member list add working :)

$apikey = "whatever-us99";                            
$list_id = "12ab34dc56";

    "apikey"        => $apikey,
    "email_address" => $email1,

            'FNAME' => $fname2,
            'LNAME' => $lname2,
    )
);

$json_data1 = json_encode($data1);
$json_data2 = json_encode($data2);

$array = array(
    "operations" => array(
        array(
            "method" => "POST",
            "path" => "/lists/$list_id/members/",
            "body" => $json_data1
        ),
        array(
            "method" => "POST",
            "path" => "/lists/$list_id/members/",
            "body" => $json_data2
        )
    )
);

$json_post = json_encode($array);

$ch = curl_init();

$curlopt_url = "https://us99.api.mailchimp.com/3.0/batches";
curl_setopt($ch, CURLOPT_URL, $curlopt_url);

curl_setopt($ch, CURLOPT_HTTPHEADER, array('Content-Type: application/json',
'Authorization: Basic '.$auth));
curl_setopt($ch, CURLOPT_USERAGENT, 'PHP-MCAPI/3.0');
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLOPT_TIMEOUT, 10);
curl_setopt($ch, CURLOPT_POST, true);
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);
curl_setopt($ch, CURLOPT_POSTFIELDS, $json_post);

print_r($json_post . "\n");
$result = curl_exec($ch);

var_dump($result . "\n");
print_r ($result . "\n");

This is a cURL function that can send or retrieve data. It should work with any PHP app that supports OAuth:

    function jwt_request($token, $post) {

       header('Content-Type: application/json'); // Specify the type of data
       $ch = curl_init('https://APPURL.com/api/json.php'); // Initialise cURL
       $post = json_encode($post); // Encode the data array into a JSON string
       $authorization = "Authorization: Bearer ".$token; // Prepare the authorisation token
       curl_setopt($ch, CURLOPT_HTTPHEADER, array('Content-Type: application/json' , $authorization )); // Inject the token into the header
       curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
       curl_setopt($ch, CURLOPT_POST, 1); // Specify the request method as POST
       curl_setopt($ch, CURLOPT_POSTFIELDS, $post); // Set the posted fields
       curl_setopt($ch, CURLOPT_FOLLOWLOCATION, 1); // This will follow any redirects
       $result = curl_exec($ch); // Execute the cURL statement
       curl_close($ch); // Close the cURL connection
       return json_decode($result); // Return the received data

    }

Use it within one-way or two-way requests:

$token = "080042cad6356ad5dc0a720c18b53b8e53d4c274"; // Get your token from a cookie or database
$post = array('some_trigger'=>'...','some_values'=>'...'); // Array of data with a trigger
$request = jwt_request($token,$post); // Send or retrieve data

I'd stick to ActionChains for this.

Here's a function which opens a new tab and switches to that tab:

import time
from selenium.webdriver.common.action_chains import ActionChains

def open_in_new_tab(driver, element, switch_to_new_tab=True):
    base_handle = driver.current_window_handle
    # Do some actions
    ActionChains(driver) \
        .move_to_element(element) \
        .key_down(Keys.COMMAND) \
        .click() \
        .key_up(Keys.COMMAND) \
        .perform()
    
    # Should you switch to the new tab?
    if switch_to_new_tab:
        new_handle = [x for x in driver.window_handles if x!=base_handle]
        assert len new_handle == 1 # assume you are only opening one tab at a time
        
        # Switch to the new window
        driver.switch_to.window(new_handle[0])

        # I like to wait after switching to a new tab for the content to load
        # Do that either with time.sleep() or with WebDriverWait until a basic
        # element of the page appears (such as "body") -- reference for this is 
        # provided below
        time.sleep(0.5)        

        # NOTE: if you choose to switch to the window/tab, be sure to close
        # the newly opened window/tab after using it and that you switch back
        # to the original "base_handle" --> otherwise, you'll experience many
        # errors and a painful debugging experience...

Here's how you would apply that function:

# Remember your starting handle
base_handle = driver.current_window_handle

# Say we have a list of elements and each is a link:
links = driver.find_elements_by_css_selector('a[href]')

# Loop through the links and open each one in a new tab
for link in links:
    open_in_new_tab(driver, link, True)
    
    # Do something on this new page
    print(driver.current_url)
    
    # Once you're finished, close this tab and switch back to the original one
    driver.close()
    driver.switch_to.window(base_handle)
    
    # You're ready to continue to the next item in your loop

Here's how you could wait until the page is loaded.

I'm going to give you an example of how I read REST headers for my controllers. My controllers only accept application/json as a request type if I have data that needs to be read. I suspect that your problem is that you have an application/octet-stream that Spring doesn't know how to handle.

Normally my controllers look like this:

@Controller
public class FooController {
    @Autowired
    private DataService dataService;

    @RequestMapping(value="/foo/", method = RequestMethod.GET)
    @ResponseBody
    public ResponseEntity<Data> getData(@RequestHeader String dataId){
        return ResponseEntity.newInstance(dataService.getData(dataId);
    }

Now there is a lot of code doing stuff in the background here so I will break it down for you.

ResponseEntity is a custom object that every controller returns. It contains a static factory allowing the creation of new instances. My Data Service is a standard service class.

The magic happens behind the scenes, because you are working with JSON, you need to tell Spring to use Jackson to map HttpRequest objects so that it knows what you are dealing with.

You do this by specifying this inside your <mvc:annotation-driven> block of your config

<mvc:annotation-driven>
    <mvc:message-converters>
        <bean class="org.springframework.http.converter.json.MappingJackson2HttpMessageConverter">
            <property name="objectMapper" ref="objectMapper" />
        </bean>
    </mvc:message-converters>
</mvc:annotation-driven>

ObjectMapper is simply an extension of com.fasterxml.jackson.databind.ObjectMapper and is what Jackson uses to actually map your request from JSON into an object.

I suspect you are getting your exception because you haven't specified a mapper that can read an Octet-Stream into an object, or something that Spring can handle. If you are trying to do a file upload, that is something else entirely.

So my request that gets sent to my controller looks something like this simply has an extra header called dataId.

If you wanted to change that to a request parameter and use @RequestParam String dataId to read the ID out of the request your request would look similar to this:

contactId : {"fooId"} 

This request parameter can be as complex as you like. You can serialize an entire object into JSON, send it as a request parameter and Spring will serialize it (using Jackson) back into a Java Object ready for you to use.

Example In Controller:

@RequestMapping(value = "/penguin Details/", method = RequestMethod.GET)
@ResponseBody
public DataProcessingResponseDTO<Pengin> getPenguinDetailsFromList(
        @RequestParam DataProcessingRequestDTO jsonPenguinRequestDTO)

Request Sent:

jsonPengiunRequestDTO: {
    "draw": 1,

            }
        },
        {

        {

                "_": "customerCampaignId",
                "header": "customerCampaignId"
            },
            "name": "customerCampaignId",
            "searchable": true,
            "orderable": true,
            "search": {
                "value": "",
                "regex": false
            }
        },
        {
            "data": {
                "_": "penguinId",
                "header": "penguinId"
            },
            "name": "penguinId",
            "searchable": false,
            "orderable": true,
            "search": {
                "value": "",
                "regex": false
            }
        },
        {
            "data": {
                "_": "validpenguin",
                "header": "validpenguin"
            },
            "name": "validpenguin",
            "searchable": true,
            "orderable": true,
            "search": {
                "value": "",
                "regex": false
            }
        },
        {
            "data": {
                "_": "",
                "header": ""
            },
            "name": "",
            "searchable": false,
            "orderable": false,
            "search": {
                "value": "",
                "regex": false
            }
        }
    ],
    "order": [
        {
            "column": 0,
            "dir": "asc"
        }
    ],
    "start": 0,
    "length": 10,
    "search": {
        "value": "",
        "regex": false
    },
    "objectId": "30"
}

which gets automatically serialized back into an DataProcessingRequestDTO object before being given to the controller ready for me to use.

As you can see, this is quite powerful allowing you to serialize your data from JSON to an object without having to write a single line of code. You can do this for @RequestParam and @RequestBody which allows you to access JSON inside your parameters or request body respectively.

Now that you have a concrete example to go off, you shouldn't have any problems once you change your request type to application/json.

use ng-intl-tel-input to validate mobile numbers for all countries. you can set default country also. on npm: https://www.npmjs.com/package/ng-intl-tel-input

more details: https://techpituwa.wordpress.com/2017/03/29/angular-js-phone-number-validation-with-ng-intl-tel-input/

This is the error line:

if (called_from.equalsIgnoreCase("add")) {  --->38th error line

This means that called_from is null. Simple check if it is null above:

String called_from = getIntent().getStringExtra("called");

if(called_from == null) {
    called_from = "empty string";
}
if (called_from.equalsIgnoreCase("add")) {
    // do whatever
} else {
    // do whatever
}

That way, if called_from is null, it'll execute the else part of your if statement.

@KyleMit's answer on Bootstrap 4 has changed a little

The Multipart File Upload worked after following code modification to Upload using RestTemplate

LinkedMultiValueMap<String, Object> map = new LinkedMultiValueMap<>();
map.add("file", new ClassPathResource(file));
HttpHeaders headers = new HttpHeaders();
headers.setContentType(MediaType.MULTIPART_FORM_DATA);

HttpEntity<LinkedMultiValueMap<String, Object>> requestEntity = new    HttpEntity<LinkedMultiValueMap<String, Object>>(
                    map, headers);
ResponseEntity<String> result = template.get().exchange(
                    contextPath.get() + path, HttpMethod.POST, requestEntity,
                    String.class);

And adding MultipartFilter to web.xml

    <filter>
        <filter-name>multipartFilter</filter-name>
        <filter-class>org.springframework.web.multipart.support.MultipartFilter</filter-class>
    </filter>
    <filter-mapping>
        <filter-name>multipartFilter</filter-name>
        <url-pattern>/*</url-pattern>
    </filter-mapping>

All your problems are that you are mixing content type negotiation with parameter passing. They are things at different levels. More specific, for your question 2, you constructed the response header with the media type your want to return. The actual content negotiation is based on the accept media type in your request header, not response header. At the point the execution reaches the implementation of the method getPersonFormat, I am not sure whether the content negotiation has been done or not. Depends on the implementation. If not and you want to make the thing work, you can overwrite the request header accept type with what you want to return.

return new ResponseEntity<>(PersonFactory.createPerson(), httpHeaders, HttpStatus.OK);

To complete the answer from Sotorios Delimanolis.

It's true that ResponseEntity gives you more flexibility but in most cases you won't need it and you'll end up with these ResponseEntity everywhere in your controller thus making it difficult to read and understand.

If you want to handle special cases like errors (Not Found, Conflict, etc.), you can add a HandlerExceptionResolver to your Spring configuration. So in your code, you just throw a specific exception (NotFoundException for instance) and decide what to do in your Handler (setting the HTTP status to 404), making the Controller code more clear.

You can simply use a controller method like this:

@RequestMapping(value = "/uploadFile", method = RequestMethod.POST)
@ResponseBody
public ResponseEntity<?> uploadFile(
    @RequestParam("file") MultipartFile file) {

  try {
    // Handle the received file here
    // ...
  }
  catch (Exception e) {
    return new ResponseEntity<>(HttpStatus.BAD_REQUEST);
  }

  return new ResponseEntity<>(HttpStatus.OK);
} // method uploadFile

Without any additional configurations for Spring Boot.

Using the following html form client side:

<html>
<body>
  <form action="/uploadFile" method="POST" enctype="multipart/form-data">
    <input type="file" name="file">
    <input type="submit" value="Upload"> 
  </form>
</body>
</html>

If you want to set limits on files size you can do it in the application.properties:

# File size limit
multipart.maxFileSize = 3Mb

# Total request size for a multipart/form-data
multipart.maxRequestSize = 20Mb

Moreover to send the file with Ajax take a look here: http://blog.netgloo.com/2015/02/08/spring-boot-file-upload-with-ajax/

Yes, use getJSONP. It's the only way to make cross domain/server async calls. (*Or it will be in the near future). Something like

$.getJSON('your-api-url/validate.php?'+$(this).serialize+'callback=?', function(data){
if(data)console.log(data);
});

The callback parameter will be filled in automatically by the browser, so don't worry.

On the server side ('validate.php') you would have something like this

<?php
if(isset($_GET))
{
//if condition is met
echo $_GET['callback'] . '(' . "{'message' : 'success', 'userID':'69', 'serial' : 'XYZ99UAUGDVD&orwhatever'}". ')';
}
else echo json_encode(array('error'=>'failed'));
?>

My answer is WRT python 2.6.2.

import commands

status, output = commands.getstatusoutput("curl -H \"Content-Type:application/json\" -k -u (few other parameters required) -X GET https://example.org -s")

print output

I apologize for not providing the required parameters 'coz it's confidential.

For Hibernate you can use the jackson-datatype-hibernate project to accommodate JSON serialization/deserialization with lazy-loaded objects.

For example,

import com.fasterxml.jackson.databind.Module;
import com.fasterxml.jackson.datatype.hibernate5.Hibernate5Module;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;

@Configuration
public class JacksonDatatypeHibernate5Configuration {

    // Register Jackson Hibernate5 Module to handle JSON serialization of lazy-loaded entities
    // Any beans of type com.fasterxml.jackson.databind.Module are automatically
    // registered with the auto-configured Jackson2ObjectMapperBuilder
    // https://docs.spring.io/spring-boot/docs/current/reference/html/howto-spring-mvc.html#howto-customize-the-jackson-objectmapper
    @Bean
    public Module hibernate5Module() {
        Hibernate5Module hibernate5Module = new Hibernate5Module();
        hibernate5Module.enable( Hibernate5Module.Feature.FORCE_LAZY_LOADING );
        hibernate5Module.disable( Hibernate5Module.Feature.USE_TRANSIENT_ANNOTATION );
        return hibernate5Module;
    }
}

In Swift 2:

extension NSMutableURLRequest {
    func setAuthorizationHeader(username username: String, password: String) -> Bool {
        guard let data = "\(username):\(password)".dataUsingEncoding(NSUTF8StringEncoding) else { return false }

        let base64 = data.base64EncodedStringWithOptions([])
        setValue("Basic \(base64)", forHTTPHeaderField: "Authorization")
        return true
    }
}

My version of @Merak Marey's Code. I am checking if files exist already and different download directories for .txt and other files

        static void DownloadAll()
    {
        string host = "xxx.xxx.xxx.xxx";
        string username = "@@@";
        string password = "123";string remoteDirectory = "/IN/";
        string finalDir = "";
        string localDirectory = @"C:\filesDN\";
        string localDirectoryZip = @"C:\filesDN\ZIP\";
        using (var sftp = new SftpClient(host, username, password))
        {
            Console.WriteLine("Connecting to " + host + " as " + username);
            sftp.Connect();
            Console.WriteLine("Connected!");
            var files = sftp.ListDirectory(remoteDirectory);

            foreach (var file in files)
            {

                string remoteFileName = file.Name;

                if ((!file.Name.StartsWith(".")) && ((file.LastWriteTime.Date == DateTime.Today)))
                { 

                    if (!file.Name.Contains(".TXT"))
                    {
                        finalDir = localDirectoryZip;
                    } 
                    else 
                    {
                        finalDir = localDirectory;
                    }


                    if (File.Exists(finalDir  + file.Name))
                    {
                        Console.WriteLine("File " + file.Name + " Exists");
                    }else{
                        Console.WriteLine("Downloading file: " + file.Name);
                          using (Stream file1 = File.OpenWrite(finalDir + remoteFileName))
                    {
                        sftp.DownloadFile(remoteDirectory + remoteFileName, file1);
                    }
                    }
                }
            }



            Console.ReadLine();

        }

Instead:

public class PhotosFragment extends Fragment

You can use:

public class PhotosFragment extends ListFragment

It change the methods

    @Override
    public void onActivityCreated(Bundle savedInstanceState) {
        super.onActivityCreated(savedInstanceState);
        ArrayList<ListviewContactItem> listContact = GetlistContact();
        setAdapter(new ListviewContactAdapter(getActivity(), listContact));
    }

onActivityCreated is void and you didn't need to return a view like in onCreateView

You can see an example here

Best solution: Goto jboss-as-7.1.1.Final\standalone\deployments folder and delete all existing files....

Run again your problem will be solved

Hibernate queries are case sensitive with property names (because they end up relying on getter/setter methods on the @Entity).

Make sure you refer to the property as fileName in the Criteria query, not filename.

Specifically, Hibernate will call the getter method of the filename property when executing that Criteria query, so it will look for a method called getFilename(). But the property is called FileName and the getter getFileName().

So, change the projection like so:

criteria.setProjection(Projections.property("fileName"));

I fixed this problem with sql command line:

connect system/<password>
alter system set processes=300 scope=spfile;
alter system set sessions=300 scope=spfile;

Restart database.

"Unexpected end of file" implies that the remote server accepted and closed the connection without sending a response. It's possible that the remote system is too busy to handle the request, or that there's a network bug that randomly drops connections.

It's also possible there is a bug in the server: something in the request causes an internal error, and the server simply closes the connection instead of sending a HTTP error response like it should. Several people suggest this is caused by missing headers or invalid header values in the request.

With the information available it's impossible to say what's going wrong. If you have access to the servers in question you can use packet sniffing tools to find what exactly is sent and received, and look at logs to of the server process to see if there are any error messages.

As mentioned in the comments to the question, the JDBC-ODBC Bridge is - as the name indicates - only a mechanism for the JDBC layer to "talk to" the ODBC layer. Even if you had a JDBC-ODBC Bridge on your Mac you would also need to have

• an implementation of ODBC itself, and
• an appropriate ODBC driver for the target database (ACE/Jet, a.k.a. "Access")

So, for most people, using JDBC-ODBC Bridge technology to manipulate ACE/Jet ("Access") databases is really a practical option only under Windows. It is also important to note that the JDBC-ODBC Bridge will be has been removed in Java 8 (ref: here).

There are other ways of manipulating ACE/Jet databases from Java, such as UCanAccess and Jackcess. Both of these are pure Java implementations so they work on non-Windows platforms. For details on how to use UCanAccess see

That code gets you the IP address of your server not the address of the client who is accessing your website. Use the HttpContext.Current.Request.UserHostAddress property to the client's IP address.

Hello this is a snippet from an old project of mine that uses curl to get ip information from some free ip databases services which reply in json format. I think it might help you.

$ip_srv = array("http://freegeoip.net/json/$this->ip","http://smart-ip.net/geoip-json/$this->ip");

getUserLocation($ip_srv);

Function:

function getUserLocation($services) {

        $ctx = stream_context_create(array('http' => array('timeout' => 15))); // 15 seconds timeout

        for ($i = 0; $i < count($services); $i++) {

            // Configuring curl options
            $options = array (
                CURLOPT_RETURNTRANSFER => true, // return web page
                //CURLOPT_HEADER => false, // don't return headers
                CURLOPT_HTTPHEADER => array('Content-type: application/json'),
                CURLOPT_FOLLOWLOCATION => true, // follow redirects
                CURLOPT_ENCODING => "", // handle compressed
                CURLOPT_USERAGENT => "test", // who am i
                CURLOPT_AUTOREFERER => true, // set referer on redirect
                CURLOPT_CONNECTTIMEOUT => 5, // timeout on connect
                CURLOPT_TIMEOUT => 5, // timeout on response
                CURLOPT_MAXREDIRS => 10 // stop after 10 redirects
            ); 

            // Initializing curl
            $ch = curl_init($services[$i]);
            curl_setopt_array ( $ch, $options );

            $content = curl_exec ( $ch );
            $err = curl_errno ( $ch );
            $errmsg = curl_error ( $ch );
            $header = curl_getinfo ( $ch );
            $httpCode = curl_getinfo ( $ch, CURLINFO_HTTP_CODE );

            curl_close ( $ch );

            //echo 'service: ' . $services[$i] . '</br>';
            //echo 'err: '.$err.'</br>';
            //echo 'errmsg: '.$errmsg.'</br>';
            //echo 'httpCode: '.$httpCode.'</br>';
            //print_r($header);
            //print_r(json_decode($content, true));

            if ($err == 0 && $httpCode == 200 && $header['download_content_length'] > 0) {

                return json_decode($content, true);

            } 

        }
    }

You do not need to select the columns separately in order to use them in your CONCAT. Simply remove them, and your query will become:

SELECT FirstName AS First_Name
     , LastName AS Last_Name
     , CONCAT(ContactPhoneAreaCode1, ContactPhoneNumber1) AS Contact_Phone 
  FROM TABLE1

You can use the fingerprintJS2 library, it helps a lot with calculating a browser fingerprint.

By the way, on Panopticlick you can see how unique this usually is.

Check this one. It will work.

You should use @RequestParam on those resources with method = RequestMethod.GET

In order to post parameters, you must send them as the request body. A body like JSON or another data representation would depending on your implementation (I mean, consume and produce MediaType).

Typically, multipart/form-data is used to upload files.

You can use various local storage mechanisms to store this data in the browser such as Web Storage, IndexedDB, WebSQL (deprecated) and File API (deprecated and only available in Chrome) (and UserData with IE).

The simplest and most widely supported is WebStorage where you have persistent storage (localStorage) or session based (sessionStorage) which is in memory until you close the browser. Both share the same API.

You can for example (simplified) do something like this when the page is about to reload:

window.onbeforeunload = function() {
    localStorage.setItem("name", $('#inputName').val());
    localStorage.setItem("email", $('#inputEmail').val());
    localStorage.setItem("phone", $('#inputPhone').val());
    localStorage.setItem("subject", $('#inputSubject').val());
    localStorage.setItem("detail", $('#inputDetail').val());
    // ...
}

Web Storage works synchronously so this may work here. Optionally you can store the data for each blur event on the elements where the data is entered.

At page load you can check:

window.onload = function() {

    var name = localStorage.getItem("name");
    if (name !== null) $('#inputName').val("name");

    // ...
}

getItem returns null if the data does not exist.

Use sessionStorage instead of localStorage if you want to store only temporary.

When publishing to IIS, by Web Deploy, I just checked the File Publish Options and executed. Now it works! After this deploy the checkboxes do not need to be checked. I don't think this can be a solutions for everybody, but it is the only thing I needed to do to solve my problem. Good luck.

you have done it the correct way using

curl_setopt($ch, CURLOPT_POSTFIELDS,$body);

but i notice your missing

curl_setopt($ch, CURLOPT_POST,1);

If your $result variable is a string json like, you must use json_decode function to parse it as an object or array:

$result = '{"Cancelled":false,"MessageID":"402f481b-c420-481f-b129-7b2d8ce7cf0a","Queued":false,"SMSError":2,"SMSIncomingMessages":null,"Sent":false,"SentDateTime":"\/Date(-62135578800000-0500)\/"}';
$json = json_decode($result, true);
print_r($json);

OUTPUT

Array
(
    [Cancelled] => 
    [MessageID] => 402f481b-c420-481f-b129-7b2d8ce7cf0a
    [Queued] => 
    [SMSError] => 2
    [SMSIncomingMessages] => 
    [Sent] => 
    [SentDateTime] => /Date(-62135578800000-0500)/
)

Now you can work with $json variable as an array:

echo $json['MessageID'];
echo $json['SMSError'];
// other stuff

Try below code,

$cookieFile = "cookies.txt";
if(!file_exists($cookieFile)) {
    $fh = fopen($cookieFile, "w");
    fwrite($fh, "");
    fclose($fh);
}


$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, $apiCall);
curl_setopt($ch, CURLOPT_POST, TRUE);
curl_setopt($ch, CURLOPT_POSTFIELDS, $jsonDataEncoded);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, TRUE);
curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, FALSE);
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, FALSE);
curl_setopt($ch, CURLOPT_HTTPHEADER, array('Content-Type: application/json'));
curl_setopt($ch, CURLOPT_COOKIEFILE, $cookieFile); // Cookie aware
curl_setopt($ch, CURLOPT_COOKIEJAR, $cookieFile); // Cookie aware
curl_setopt($ch, CURLOPT_VERBOSE, true);
if(!curl_exec($ch)){
    die('Error: "' . curl_error($ch) . '" - Code: ' . curl_errno($ch));
}
else{
    $response = curl_exec($ch); 
}
curl_close($ch);
$result = json_decode($response, true);

echo '<pre>';
var_dump($result);
echo'</pre>';

I hope this will help you.

When trying to set up a .NET Core 1.0 website I got this error, and tried everything else I could find with no luck, including checking the web.config file, IIS_IUSRS permissions, IIS URL rewrite module, etc. In the end, I installed DotNetCore.1.0.0-WindowsHosting.exe from this page: https://www.microsoft.com/net/download and it started working right away.

The RestTemplate getForObject() method does not support setting headers. The solution is to use the exchange() method.

So instead of restTemplate.getForObject(url, String.class, param) (which has no headers), use

HttpHeaders headers = new HttpHeaders();
headers.set("Header", "value");
headers.set("Other-Header", "othervalue");
...

HttpEntity entity = new HttpEntity(headers);

ResponseEntity<String> response = restTemplate.exchange(
    url, HttpMethod.GET, entity, String.class, param);

Finally, use response.getBody() to get your result.

This question is similar to this question.

Following work for me:

Keep following setting blank if you have made in build.gradle.

signingConfigs {
        release {
            storePassword ""
            keyAlias ""
            keyPassword ""
        }
    }

and choose Gradle Task from your Editor window. It will show list of all flavor if you have created.

I can tell you I am using just a single breakpoint at 768 - that is min-width: 768px to serve tablets and desktops, and max-width: 767px to serve phones.

I haven't looked back since. It makes the responsive development easy and not a chore, and provides a reasonable experience on all devices at minimal cost to development time without the need to fear a new Android device with a new resolution you haven't factored in.

We encountered this error after an upgrade from 2008 to 2014 SQL Server where our some of our previous connection strings for local development had a Data Source=./ like this

        <add name="MyLocalDatabase" connectionString="Data Source=./;Initial Catalog=SomeCatalog;Integrated Security=SSPI;Application Name=MyApplication;"/>

Changing that from ./ to either (local) or localhost fixed the problem.

<add name="MyLocalDatabase" connectionString="Data Source=(local);Initial Catalog=SomeCatalog;Integrated Security=SSPI;Application Name=MyApplication;"/>

You must set proxy server for gradle at some time, you can try to change the proxy server ip address in gradle.properties which is under .gradle document

I'm going to answer my own question.

1. innerJoin should use the keyword "WITH" instead of "ON" (Doctrine's documentation [13.2.6. Helper methods] is inaccurate; [13.2.5. The Expr class] is correct)
2. no need to link foreign keys in join condition as they're already specified in the entity mapping.

Therefore, the following works for me

$qb->select('c')
    ->innerJoin('c.phones', 'p', 'WITH', 'p.phone = :phone')
    ->where('c.username = :username');

or

$qb->select('c')
    ->innerJoin('c.phones', 'p', Join::WITH, $qb->expr()->eq('p.phone', ':phone'))
    ->where('c.username = :username');

There is a library named Picasso which can efficiently load images from a URL. It can also load an image from a file.

Examples:

1. Load URL into ImageView without generating a bitmap:

   Picasso.with(context) // Context
          .load("http://abc.imgur.com/gxsg.png") // URL or file
          .into(imageView); // An ImageView object to show the loaded image
   

2. Load URL into ImageView by generating a bitmap:

   Picasso.with(this)
          .load(artistImageUrl)
          .into(new Target() {
              @Override
              public void onBitmapLoaded(final Bitmap bitmap, Picasso.LoadedFrom from) {
                  /* Save the bitmap or do something with it here */
   
                  // Set it in the ImageView
                  theView.setImageBitmap(bitmap)
              }
   
              @Override
              public void onBitmapFailed(Drawable errorDrawable) {
   
              }
   
              @Override
              public void onPrepareLoad(Drawable placeHolderDrawable) {
   
              }
          });
   

There are many more options available in Picasso. Here is the documentation.

Make a method of MsgBox in your page.

public void MsgBox(String ex, Page pg,Object obj) 
{
    string s = "<SCRIPT language='javascript'>alert('" + ex.Replace("\r\n", "\\n").Replace("'", "") + "'); </SCRIPT>";
    Type cstype = obj.GetType();
    ClientScriptManager cs = pg.ClientScript;
    cs.RegisterClientScriptBlock(cstype, s, s.ToString());
}

and when you want to use msgbox just put this line

MsgBox("! your message !", this.Page, this);

Following what curl does internally for the request (via the method outlined in this answer to "Php - Debugging Curl") answers the question: No, it is not possible to use the curl_setopt call with CURLOPT_HTTPHEADER. The second call will overwrite the headers of the first call.

Instead the function needs to be called once with all headers:

$headers = array(
    'Content-type: application/xml',
    'Authorization: gfhjui',
);
curl_setopt($curlHandle, CURLOPT_HTTPHEADER, $headers);

Related (but different) questions are:

• How to send a header using a HTTP request through a curl call? (curl on the commandline)
• How to get an option previously set with curl_setopt()? (curl PHP extension)

I had to solve a similar problem--I wanted certain styles to only apply to mobile devices in landscape mode. Essentially the fonts and line spacing looked fine in every other context, so I just needed the one exception for mobile landscape. This media query worked perfectly:

@media all and (max-width: 600px) and (orientation:landscape) 
{
    /* styles here */
}

A cleaner approach would be to create a Person object that contains contactName, contactPhone, etc. Then, use an ArrayList rather then an array to add the new objects. Create a loop that accepts all the fields for each `Person:

while (!done) {
   Person person = new Person();
   String name = input.nextLine();
   person.setContactName(name);
   ...

   myPersonList.add(person);
}

Using the list will remove the need for array bounds checking.

for wamp server use 10.0.2.2 for local host e.g. 10.0.2.2/phpMyAdmin

and for tomcat use 10.0.2.2:8080/server

i agree with you about alternative solutions which you mentioned above

1. Use POST instead of GET;
2. Transform the List into a JSON string and pass it to the service.

and its true that you can't add List to MultiValuedMap because of its impl class MultivaluedMapImpl have capability to accept String Key and String Value. which is shown in following figure

still you want to do that things than try following code.

Had to debug a site for native Android browser and came here. So I tried weinre on an OS X 10.9 (as weinre server) with Firefox 30.0 (weinre client) and an Android 4.1.2 (target). I'm really, really surprised of the result.

1. Download and install node runtime from http://nodejs.org/download/
2. Install weinre: sudo npm -g install weinre
3. Find out your current IP address at Settings > Network
4. Setup a weinre server on your machine: weinre --boundHost YOUR.IP.ADDRESS.HERE
5. In your browser call: http://YOUR.IP.ADRESS.HERE:8080
6. You'll see a script snippet, place it into your site: <script src="http://YOUR.IP.ADDRESS.HERE:8080/target/target-script-min.js"></script>
7. Open the debug client in your local browser: http://YOUR.IP.ADDRESS.HERE:8080/client
8. Finally on your Android: call the site you want to inspect (the one with the script inside) and see how it appears as "Target" in your local browser. Now you can open "Elements" or whatever you want.

Maybe 8080 isn't your default port. Then in step 4 you have to call weinre --httpPort YOURPORT --boundHost YOUR.IP.ADRESS.HERE.

And I don't remember exactly when it was, maybe somewhere after step 5, I had to accept incoming connections prompt, of course.

Happy debugging

P.S. I'm still overwhelmed how good that works. Even elements-highlighting work

Update-Package -reinstall Microsoft.Web.Infrastructure didn't work for me, as I kept receiving errors that it was already installed.

I had to navigate to the Microsoft.Web.Infrastructure.1.0.0.0 folder in the packages folder and manually delete that folder.

After doing this, running Install-Package Microsoft.Web.Infrastructure installed it.

I faced this error (errno 121) but it was caused by mysql-created intermediate tables that had been orphaned, preventing me from altering a table even though no such constraint name existed across any of my tables. At some point, my MySQL had crashed or failed to cleanup an intermediate table (table name starting with a #sql-) which ended up presenting me with an error such as: Can't create table '#sql-' (errno 121) when trying to run an ALTER TABLE with certain constraint names.

According to the docs at http://dev.mysql.com/doc/refman/5.7/en/innodb-troubleshooting-datadict.html , you can search for these orphan tables with:

SELECT * FROM INFORMATION_SCHEMA.INNODB_SYS_TABLES WHERE NAME LIKE '%#sql%';

The version I was working with was 5.1, but the above command only works on versions >= 5.6 (manual is incorrect about it working for 5.5 or earlier, because INNODB_SYS_TABLES does not exist in such versions). I was able to find the orphaned temporary table (which did not match the one named in the message) by searching my mysql data directory in command line:

find . -iname '#*'

After discovering the filename, such as #sql-9ad_15.frm, I was able to drop that orphaned table in MySQL:

USE myschema;
DROP TABLE `#mysql50##sql-9ad_15`;

After doing so, I was then able to successfully run my ALTER TABLE.

For completeness, as per the MySQL documentation linked, "the #mysql50# prefix tells MySQL to ignore file name safe encoding introduced in MySQL 5.1."

use "Content-type: application/x-www-form-urlencoded" instead of "application/json"

Sometimes it is the simple things. In my case, I had an invalid url. I had left out a colon before the at sign (@). I had "jdbc:oracle:thin@//localhost" instead of "jdbc:oracle:thin:@//localhost" Hope this helps someone else with this issue.

It's not possible to configure an IIS managed handler to run in classic mode. You should be running IIS in integrated mode if you want to do that.

You can learn more about modules, handlers and IIS modes in the following blog post:

IIS 7.0, ASP.NET, pipelines, modules, handlers, and preconditions

For handlers, if you set preCondition="integratedMode" in the mapping, the handler will only run in integrated mode. On the other hand, if you set preCondition="classicMode" the handler will only run in classic mode. And if you omit both of these, the handler can run in both modes, although this is not possible for a managed handler.

Try with the following code

public static ArrayList<Customer> getAllCustomer() throws ClassNotFoundException, SQLException {
    Connection conn=DBConnection.getDBConnection().getConnection();
    Statement stm;
    stm = conn.createStatement();
    String sql = "Select * From Customer";
    ResultSet rst;
    rst = stm.executeQuery(sql);
    ArrayList<Customer> customerList = new ArrayList<>();
    while (rst.next()) {
        Customer customer = new Customer(rst.getString("id"), rst.getString("name"), rst.getString("address"), rst.getDouble("salary"));
        customerList.add(customer);
    }
    return customerList;
}

this is my model class

public class Customer {
private String id;
private String name;
private String salary;
private String address;

    return id;

I just made a JSFiddle that show pagination + search + order by on each column using Build with Twitter Bootstrap code: http://jsfiddle.net/SAWsA/11/

checkout the example here

http://svn.apache.org/repos/asf/poi/trunk/src/examples/src/org/apache/poi/ss/examples/BusinessPlan.java

style.setFillForegroundColor(IndexedColors.LIGHT_CORNFLOWER_BLUE.getIndex());

Try like this:

$url = 'url_to_post';
// this is only part of the data you need to sen
$customer_data = array("first_name" => "First name","last_name" => "last name","email"=>"[email protected]","addresses" => array ("address1" => "some address" ,"city" => "city","country" => "CA", "first_name" =>  "Mother","last_name" =>  "Lastnameson","phone" => "555-1212", "province" => "ON", "zip" => "123 ABC" ) );
// As per your API, the customer data should be structured this way
$data = array("customer" => $customer_data);
// And then encoded as a json string
$data_string = json_encode($data);
$ch=curl_init($url);

curl_setopt_array($ch, array(
    CURLOPT_POST => true,
    CURLOPT_POSTFIELDS => $data_string,
    CURLOPT_HEADER => true,
    CURLOPT_HTTPHEADER => array('Content-Type:application/json', 'Content-Length: ' . strlen($data_string)))

$result = curl_exec($ch);
curl_close($ch);

The key thing you've forgotten was to json_encode your data. But you also may find it convenient to use curl_setopt_array to set all curl options at once by passing an array.

parag-chauhan and devrim answers are perfect, but i change the onActivityResult without cursor, and it makes the code much more better.

I was recently dealing with an issue when I was trying to get past authentication while making a REST call from Java, and while the answers in this thread (and other threads) helped, there was still a bit of trial and error involved in getting it working.

What worked for me was encoding credentials in Base64 and adding them as Basic Authorization headers. I then added them as an HttpEntity to restTemplate.postForEntity, which gave me the response I needed.

Here's the class I wrote for this in full (extending RestTemplate):

public class AuthorizedRestTemplate extends RestTemplate{

    private String username;
    private String password;

    public AuthorizedRestTemplate(String username, String password){
        this.username = username;
        this.password = password;
    }

    public String getForObject(String url, Object... urlVariables){
        return authorizedRestCall(this, url, urlVariables);
    }

    private String authorizedRestCall(RestTemplate restTemplate, 
            String url, Object... urlVariables){
        HttpEntity<String> request = getRequest();
        ResponseEntity<String> entity = restTemplate.postForEntity(url, 
                request, String.class, urlVariables);
        return entity.getBody();
    }

    private HttpEntity<String> getRequest(){
        HttpHeaders headers = new HttpHeaders();
        headers.add("Authorization", "Basic " + getBase64Credentials());
        return new HttpEntity<String>(headers);
    }

    private String getBase64Credentials(){
        String plainCreds = username + ":" + password;
        byte[] plainCredsBytes = plainCreds.getBytes();
        byte[] base64CredsBytes = Base64.encodeBase64(plainCredsBytes);
        return new String(base64CredsBytes);
    }
}

Normally this error means that a connection was established with a server but that connection was closed by the remote server. This could be due to a slow server, a problem with the remote server, a network problem, or (maybe) some kind of security error with data being sent to the remote server but I find that unlikely.

Normally a network error will resolve itself given a bit of time, but it sounds like you’ve already given it a bit of time.

cURL sometimes having issue with SSL and SSL certificates. I think that your Apache and/or PHP was compiled with a recent version of the cURL and cURL SSL libraries plus I don't think that OpenSSL was installed in your web server.

Although I can not be certain However, I believe cURL has historically been flakey with SSL certificates, whereas, Open SSL does not.

Anyways, try installing Open SSL on the server and try again and that should help you get rid of this error.

According to the docs: http://web.archive.org/web/20170909233829/https://source.android.com/devices/tech/dalvik/configure an .odex file:

contains AOT compiled code for methods in the APK.

Furthermore, they appear to be regular shared libraries, since if you get any app, and check:

file /data/app/com.android.appname-*/oat/arm64/base.odex

it says:

base.odex: ELF shared object, 64-bit LSB arm64, stripped

and aarch64-linux-gnu-objdump -d base.odex seems to work and give some meaningful disassembly (but also some rubbish sections).

The directory where st.rb lives is most likely not on your load path.

Assuming that st.rb is located in a directory called lib relative to where you invoke irb, you can add that lib directory to the list of directories that ruby uses to load classes or modules with this:

$: << 'lib'

For example, in order to call the module called 'foobar' (foobar.rb) that lives in the lib directory, I would need to first add the lib directory to the list of load path. Here, I am just appending the lib directory to my load path:

irb(main):001:0> require 'foobar'
LoadError: no such file to load -- foobar
        from /usr/lib/ruby/site_ruby/1.8/rubygems/custom_require.rb:36:in `gem_original_require'
        from /usr/lib/ruby/site_ruby/1.8/rubygems/custom_require.rb:36:in `require'
        from (irb):1
irb(main):002:0> $:
=> ["/usr/lib/ruby/gems/1.8/gems/spoon-0.0.1/lib", "/usr/lib/ruby/gems/1.8/gems/interactive_editor-0.0.10/lib", "/usr/lib/ruby/site_ruby/1.8", "/usr/lib/ruby/site_ruby/1.8/i386-cygwin", "/usr/lib/ruby/site_ruby", "/usr/lib/ruby/vendor_ruby/1.8", "/usr/lib/ruby/vendor_ruby/1.8/i386-cygwin", "/usr/lib/ruby/vendor_ruby", "/usr/lib/ruby/1.8", "/usr/lib/ruby/1.8/i386-cygwin", "."]
irb(main):004:0> $: << 'lib'
=> ["/usr/lib/ruby/gems/1.8/gems/spoon-0.0.1/lib", "/usr/lib/ruby/gems/1.8/gems/interactive_editor-0.0.10/lib", "/usr/lib/ruby/site_ruby/1.8", "/usr/lib/ruby/site_ruby/1.8/i386-cygwin", "/usr/lib/ruby/site_ruby", "/usr/lib/ruby/vendor_ruby/1.8", "/usr/lib/ruby/vendor_ruby/1.8/i386-cygwin", "/usr/lib/ruby/vendor_ruby", "/usr/lib/ruby/1.8", "/usr/lib/ruby/1.8/i386-cygwin", ".", "lib"]
irb(main):005:0> require 'foobar'
=> true

EDIT Sorry, I completely missed the fact that you are using ruby 1.9.x. All accounts report that your current working directory has been removed from LOAD_PATH for security reasons, so you will have to do something like in irb:

$: << "."

In my opinion, it is not possible for the like button (and I hope it is not possible).

But, you can trigger a custom OpenGraph v2 action, or display a like button linked to your facebook page.

Just use crontab -e and follow the tutorial here.

Look at point 3 for a guide on how to specify the frequency.

Based on your requirement, it should effectively be:

*/10 * * * * /usr/bin/python script.py

Android needs to be compiled for every hardware plattform / every device model seperatly with the specific drivers etc. If you manage to do that you need also break the security arrangements every manufacturer implements to prevent the installation of other software - these are also different between each model / manufacturer. So it is possible at in theory, but only there :-)

You problem is that your string are unquoted. Which mean that they are interpreted by your database engine as a column name.

You need to create parameters in order to pass your value to the query.

 cmd.CommandText = "INSERT INTO Data (Name, PhoneNo, Address) VALUES (@Name, @PhoneNo, @Address);";
 cmd.Parameters.AddWithValue("@Name", txtName.Text);
 cmd.Parameters.AddWithValue("@PhoneNo", txtPhone.Text);
 cmd.Parameters.AddWithValue("@Address", txtAddress.Text);

OK, so I'm being an idiot and I'm confusing query parameters with url parameters. I was kinda hoping there would be a nicer way to populate my query parameters rather than an ugly concatenated String but there we are. It's simply a case of build the URL with the correct parameters. If you pass it as a String Spring will also take care of the encoding for you.

I tried what Samuel Slade has suggested. Didn't work for me. The PropertyInfo list was coming as empty. So, I tried the following and it worked for me.

    Type type = typeof(Record);
    FieldInfo[] properties = type.GetFields();
    foreach (FieldInfo property in properties) {
       Debug.LogError(property.Name);
    }

This is a problem which can occur when there is an old version of a DLL still lingering somewhere around. Make sure that the latest assemblies are deployed and no duplicated older assemblies are hiding in certain folders. Your best bet would be to delete every built item and rebuild/redeploy the entire solution.

Have you tried to set the value of the static DefaultConnectionLimit property programmatically?

Here is a good source of information about that true headache... ASP.NET Thread Usage on IIS 7.5, IIS 7.0, and IIS 6.0, with updates for framework 4.0.

Just keep the following in mind.

In IIS if you have a folder for example called Pages with multiple websites in it. Website will inherit settings from the web.config file from the parent directory. So even if the folder page (in this example Pages) isn't a website but contains a web.config file, all websites listed inside of it will inherit the setting.

Just wanted to update this thread for future developers.

JQuery >1.12 Now supports being able to change every little piece of the request through JQuery.post ($.post({...}). see second function signature in https://api.jquery.com/jquery.post/

I just had this idea, so maybe it's shortsighted, but it seems to work well and might be the most consistent between your CSS and JS.

In your CSS you set the max-width value for html based on the @media screen value:

@media screen and (max-width: 480px) and (orientation: portrait){

    html { 
        max-width: 480px;
    }

    ... more styles for max-width 480px screens go here

}

Then, using JS (probably via a framework like JQuery), you would just check the max-width value of the html tag:

maxwidth = $('html').css('max-width');

Now you can use this value to make conditional changes:

If (maxwidth == '480px') { do something }

If putting the max-width value on the html tag seems scary, then maybe you can put on a different tag, one that is only used for this purpose. For my purpose the html tag works fine and doesn't affect my markup.

Useful if you are using Sass, etc: To return a more abstract value, such as breakpoint name, instead of px value you can do something like:

1. Create an element that will store the breakpoint name, e.g. <div id="breakpoint-indicator" />
2. Using css media queries change the content property for this element, e. g. "large" or "mobile", etc (same basic media query approach as above, but setting css 'content' property instead of 'max-width').
3. Get the css content property value using js or jquery (jquery e.g. $('#breakpoint-indicator').css('content');), which returns "large", or "mobile", etc depending on what the content property is set to by the media query.
4. Act on the current value.

Now you can act on same breakpoint names as you do in sass, e.g. sass: @include respond-to(xs), and js if ($breakpoint = "xs) {}.

What I especially like about this is that I can define my breakpoint names all in css and in one place (likely a variables scss document) and my js can act on them independently.

This awnser solved my problem. Below is a copy of it:

Make sure to start you JVM with -Dfile.encoding=UTF-8. You JVM defaults to the operating system charset

This is a JVM argument which could be added, for example, either to JBoss standalone or JBoss running from Eclipse.

In my case, this problem happened isolatelly on only one of my team people's computer. All the others was working without this problem.

This is really simple , just add this in web.config

<system.webServer>
  <httpProtocol>
    <customHeaders>
      <add name="Access-Control-Allow-Origin" value="http://localhost" />
      <add name="Access-Control-Allow-Headers" value="X-AspNet-Version,X-Powered-By,Date,Server,Accept,Accept-Encoding,Accept-Language,Cache-Control,Connection,Content-Length,Content-Type,Host,Origin,Pragma,Referer,User-Agent" />
      <add name="Access-Control-Allow-Methods" value="GET, PUT, POST, DELETE, OPTIONS" />
      <add name="Access-Control-Max-Age" value="1000" />
    </customHeaders>
  </httpProtocol>
</system.webServer>

In Origin put all domains that have access to your web server, in headers put all possible headers that any ajax http request can use, in methods put all methods that you allow on your server

if you are using Spring version of 3.1 or newer you can specify "produces" in @RequestMapping annotation. Example below works for me out of box. No need of register converter or anything else if you have web mvc enabled (@EnableWebMvc).

@ResponseBody
@RequestMapping(value = "/photo2", method = RequestMethod.GET, produces = MediaType.IMAGE_JPEG_VALUE)
public byte[] testphoto() throws IOException {
    InputStream in = servletContext.getResourceAsStream("/images/no_image.jpg");
    return IOUtils.toByteArray(in);

C++11 standard on jumping over some initializations

JohannesD gave an explanation, now for the standards.

The C++11 N3337 standard draft 6.7 "Declaration statement" says:

3 It is possible to transfer into a block, but not in a way that bypasses declarations with initialization. A program that jumps (87) from a point where a variable with automatic storage duration is not in scope to a point where it is in scope is ill-formed unless the variable has scalar type, class type with a trivial default constructor and a trivial destructor, a cv-qualified version of one of these types, or an array of one of the preceding types and is declared without an initializer (8.5).

87) The transfer from the condition of a switch statement to a case label is considered a jump in this respect.

[ Example:

void f() {
   // ...
  goto lx;    // ill-formed: jump into scope of a
  // ...
ly:
  X a = 1;
  // ...
lx:
  goto ly;    // OK, jump implies destructor
              // call for a followed by construction
              // again immediately following label ly
}

— end example ]

As of GCC 5.2, the error message now says:

crosses initialization of

C

C allows it: c99 goto past initialization

The C99 N1256 standard draft Annex I "Common warnings" says:

2 A block with initialization of an object that has automatic storage duration is jumped into

If you don't do anything in your bash script than run the php one, you could simply run the php script from cron with a command like /usr/bin/php /path/to/your/file.php.

That is, you are referencing an image, but instead of providing an external url, the png image data is in the url itself, embedded in the style sheet. data:image/png;base64 tells the browser that the data is inline, is a png image and is in this case base64 encoded. The encoding is needed because png images can contain bytes that are invalid inside a HTML document (or within the HTTP protocol even).

Just been doing that myself today... here is code I have working for me...

$data = array("a" => $a);
$ch = curl_init($url);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLOPT_CUSTOMREQUEST, "PUT");
curl_setopt($ch, CURLOPT_POSTFIELDS,http_build_query($data));

$response = curl_exec($ch);

if (!$response) 
{
    return false;
}

Your onTap override receives the MapView from which you can obtain the Context:

@Override
public boolean onTap(GeoPoint p, MapView mapView)

    Intent intent = new Intent();
    intent.setClass(mapView.getContext(), FullscreenView.class);
    startActivity(intent);

    // ...
}

Whenever one writes [A-Z] or [a-z], one explicitly commits to processing nothing but 7-bit ASCII data from the 1960s. If that’s really ok, then fine. But if it’s not ok, then Unicode character properties exist to help you with handling modern character data.

There are three cases in Unicode, not two. Furthermore, you also have noncased letters. Letters in general are specified by the \pL property, and each of these also belongs to exactly one of five subcategories:

1. uppercase letters, specified with \p{Lu}; eg: AÇ?ÞSSS??ST
2. titlecase letters, specified with \p{Lt}; eg: ??Ss?St (actually Ss and St are an upper- and then a lowercase letter, but they are what you get if you ask for the titlecase of ß and ?, respectively)
3. lowercase letters, specified with \p{Ll}; eg: aaç??sþß??
4. modifier letters, specified with \p{Lm}; eg: ????"'???
5. other letters, specified with \p{Lo}; eg: ?????

You can take the complement of any of these, but do be careful, because something like \P{Lu} does not mean a letter that isn’t uppercase! It means any character that isn’t an uppercase letter.

For a letter that’s either of uppercase or titlecase, use [\p{Lu}\p{Lt}]. So you could use for your pattern:

 ^([\p{Lu}\p{Lt}]\p{Ll}+)+$

If you don’t mean to limit the letters following the first to the “casing” letters alone, then you might prefer:

 ^([\p{Lu}\p{Lt}][\p{Ll}\p{Lm}\p{Lo}]+)+$

If you’re trying to match so-called “CamelCase” identifiers, then the actual rules depend on the programming language, but usually include the underscore character and the decimal numbers (\p{Nd}), and may also include a literal dollar sign and other language-dependent characters. If so, you may wish to add some of these to one or the other of the two character classes provided above.

For example, you may wish to add underscore to both but digits only to the second, leaving you with:

 ^([_\p{Lu}\p{Lt}][_\p{Nd}\p{Ll}\p{Lm}\p{Lo}]+)+$

If, though, you are dealing with certain “words” from various RFCs and ISO standards, these are often specified as containing ASCII only. If so, you can get by with the literal [A-Z] idea. It’s just not kind to impose that restriction if it doesn’t actually exist.

From ioS 7 onwards, there are newer ways for apps to run in background. Apple now recognizes that apps have to constantly download and process data constantly.

Here is the new list of all the apps which can run in background.

1. Apps that play audible content to the user while in the background, such as a music player app
2. Apps that record audio content while in the background.
3. Apps that keep users informed of their location at all times, such as a navigation app
4. Apps that support Voice over Internet Protocol (VoIP)
5. Apps that need to download and process new content regularly
6. Apps that receive regular updates from external accessories

You can declare app's supported background tasks in Info.plist using X Code 5+. For eg. adding UIBackgroundModes key to your app’s Info.plist file and adding a value of 'fetch' to the array allows your app to regularly download and processes small amounts of content from the network. You can do the same in the 'capabilities' tab of Application properties in XCode 5 (attaching a snapshot)

You can find more about this in Apple documentation

When our page is idle for x amount of time the view will expire and throw javax.faces.application.ViewExpiredException to prevent this from happening one solution is to create CustomViewHandler that extends ViewHandler and override restoreView method all the other methods are being delegated to the Parent

import java.io.IOException;
import javax.faces.FacesException;
import javax.faces.application.ViewHandler;
import javax.faces.component.UIViewRoot;
import javax.faces.context.FacesContext;
import javax.servlet.http.HttpServletRequest;

public class CustomViewHandler extends ViewHandler {
    private ViewHandler parent;

    public CustomViewHandler(ViewHandler parent) {
        //System.out.println("CustomViewHandler.CustomViewHandler():Parent View Handler:"+parent.getClass());
        this.parent = parent;
    }

    @Override 
    public UIViewRoot restoreView(FacesContext facesContext, String viewId) {
    /**
     * {@link javax.faces.application.ViewExpiredException}. This happens only  when we try to logout from timed out pages.
     */
        UIViewRoot root = null;
        root = parent.restoreView(facesContext, viewId);
        if(root == null) {
            root = createView(facesContext, viewId);
        }
        return root;
    }

    @Override
    public Locale calculateLocale(FacesContext facesContext) {
        return parent.calculateLocale(facesContext);
    }

    @Override
    public String calculateRenderKitId(FacesContext facesContext) {
        String renderKitId = parent.calculateRenderKitId(facesContext);
        //System.out.println("CustomViewHandler.calculateRenderKitId():RenderKitId: "+renderKitId);
        return renderKitId;
    }

    @Override
    public UIViewRoot createView(FacesContext facesContext, String viewId) {
        return parent.createView(facesContext, viewId);
    }

    @Override
    public String getActionURL(FacesContext facesContext, String actionId) {
        return parent.getActionURL(facesContext, actionId);
    }

    @Override
    public String getResourceURL(FacesContext facesContext, String resId) {
        return parent.getResourceURL(facesContext, resId);
    }

    @Override
    public void renderView(FacesContext facesContext, UIViewRoot viewId) throws IOException, FacesException {
        parent.renderView(facesContext, viewId);
    }

    @Override
    public void writeState(FacesContext facesContext) throws IOException {
        parent.writeState(facesContext);
    }

    public ViewHandler getParent() {
        return parent;
    }

}   

Then you need to add it to your faces-config.xml

<application>
    <view-handler>com.demo.CustomViewHandler</view-handler>
</application>

To make cURL follow a redirect, use:

curl_setopt($ch, CURLOPT_FOLLOWLOCATION, true);

Erm... I don't think you're actually executing the curl... Try:

curl_exec($ch);

...after setting the options, and before the curl_getinfo() call.

EDIT: If you just want to find out where a page redirects to, I'd use the advice here, and just use Curl to grab the headers and extract the Location: header from them:

$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_HEADER, true);
curl_setopt($ch, CURLOPT_FOLLOWLOCATION, false);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
$result = curl_exec($ch);
if (preg_match('~Location: (.*)~i', $result, $match)) {
   $location = trim($match[1]);
}

The faster way for your case is:

    jTable.repaint(); // Repaint all the component (all Cells).

The optimized way when one or few cell change:

    ((AbstractTableModel) jTable.getModel()).fireTableCellUpdated(x, 0); // Repaint one cell.

See documentation: http://www.php.net/manual/en/function.curl-setopt.php

CURLOPT_CONNECTTIMEOUT - The number of seconds to wait while trying to connect. Use 0 to wait indefinitely.
CURLOPT_TIMEOUT - The maximum number of seconds to allow cURL functions to execute.

curl_setopt($ch, CURLOPT_CONNECTTIMEOUT, 0); 
curl_setopt($ch, CURLOPT_TIMEOUT, 400); //timeout in seconds

also don't forget to enlarge time execution of php script self:

set_time_limit(0);// to infinity for example

I had the same error. I had an IIS site with .net framework version 2.0, but my app needed 4.0. I changed the version and it worked.

Posting just as a reminder if someone might have the same issue.

I have found another reason: different versions used for icons in toolbox and references in the project. After inserting the objects in some form, the error started.

I have seen that the new versions when you define the resulting entities better define them in the following way if you handle a different scheme, I had a similar problem

You must add System.ComponentModel.DataAnnotations.Schema

using System.ComponentModel.DataAnnotations.Schema;


 [Table("InstitucionesMilitares", Schema = "configuracion")]

I got the same error when:

Using a custom ModelView, both Actions (GET and POST) were passing the ModelView that contained two objects:

public ActionResult Add(int? categoryID)
{
    ...
    ProductViewModel productViewModel = new ProductViewModel(
            product,
            rootCategories
            );
    return View(productViewModel); 
}

And the POST also accepting the same model view:

[HttpPost]
[ValidateInput(false)]
public ActionResult Add(ProductModelView productModelView)
{...}

Problem was the View received the ModelView (needed both product and list of categories info), but after submitted was returning only the Product object, but as the POST Add expected a ProductModelView it passed a NULL but then the ProductModelView only constructor needed two parameters(Product, RootCategories), then it tried to find another constructor with no parameters for this NULL case then fails with "no parameterles..."

So, fixing the POST Add as follows correct the problem:

[HttpPost]
[ValidateInput(false)]
public ActionResult Add(Product product)
{...}

Hope this can help somebody (I spent almost half day to find this out!).

Use FirstOrDefault insted of SingleOrDefault..

SingleOrDefault returns a SINGLE element or null if no element is found. If 2 elements are found in your Enumerable then it throws the exception you are seeing

FirstOrDefault returns the FIRST element it finds or null if no element is found. so if there are 2 elements that match your predicate the second one is ignored

   public int GetPackage(int id,int emp)
           {
             int getpackages=Convert.ToInt32(EmployerSubscriptionPackage.GetAllData().Where(x
   => x.SubscriptionPackageID ==`enter code here` id && x.EmployerID==emp ).FirstOrDefault().ID);
               return getpackages;
           }

 1. var EmployerId = Convert.ToInt32(Session["EmployerId"]);
               var getpackage = GetPackage(employerSubscription.ID, EmployerId);

Any Class that implements System.Web.IHttpHandler Interface becomes HttpHandler. And this class run as processes in response to a request made to the ASP.NET Site.

The most common handler is an ASP.NET page handler that processes .aspx files. When users request an .aspx file, the request is processed by the page through the page handler(The Class that implements System.Web.IHttpHandler Interface).

You can create your own custom HTTP handlers that render custom output to the browser.

Some ASP.NET default handlers are:

1. Page Handler (.aspx) – Handles Web pages
2. User Control Handler (.ascx) – Handles Web user control pages
3. Web Service Handler (.asmx) – Handles Web service pages
4. Trace Handler (trace.axd) – Handles trace functionality

It seems that you have forgotten to add your state server address in the config file.

 <sessionstate mode="StateServer" timeout="20" server="127.0.0.1" port="42424" />

In order to add attributes, XSL wants

<xsl:element name="img">
     (attributes)
</xsl:element>

instead of just

<img>
     (attributes)
</img>

Although, yes, if you're just copying the element as-is, you don't need any of that.

I believe there's no such option. Alternatively you can try this

set text=Hello
set text=%text% world
echo %text%

_tmain does not exist in C++. main does.

_tmain is a Microsoft extension.

main is, according to the C++ standard, the program's entry point. It has one of these two signatures:

int main();
int main(int argc, char* argv[]);

Microsoft has added a wmain which replaces the second signature with this:

int wmain(int argc, wchar_t* argv[]);

And then, to make it easier to switch between Unicode (UTF-16) and their multibyte character set, they've defined _tmain which, if Unicode is enabled, is compiled as wmain, and otherwise as main.

As for the second part of your question, the first part of the puzzle is that your main function is wrong. wmain should take a wchar_t argument, not char. Since the compiler doesn't enforce this for the main function, you get a program where an array of wchar_t strings are passed to the main function, which interprets them as char strings.

Now, in UTF-16, the character set used by Windows when Unicode is enabled, all the ASCII characters are represented as the pair of bytes \0 followed by the ASCII value.

And since the x86 CPU is little-endian, the order of these bytes are swapped, so that the ASCII value comes first, then followed by a null byte.

And in a char string, how is the string usually terminated? Yep, by a null byte. So your program sees a bunch of strings, each one byte long.

In general, you have three options when doing Windows programming:

• Explicitly use Unicode (call wmain, and for every Windows API function which takes char-related arguments, call the -W version of the function. Instead of CreateWindow, call CreateWindowW). And instead of using char use wchar_t, and so on
• Explicitly disable Unicode. Call main, and CreateWindowA, and use char for strings.
• Allow both. (call _tmain, and CreateWindow, which resolve to main/_tmain and CreateWindowA/CreateWindowW), and use TCHAR instead of char/wchar_t.

The same applies to the string types defined by windows.h: LPCTSTR resolves to either LPCSTR or LPCWSTR, and for every other type that includes char or wchar_t, a -T- version always exists which can be used instead.

Note that all of this is Microsoft specific. TCHAR is not a standard C++ type, it is a macro defined in windows.h. wmain and _tmain are also defined by Microsoft only.

It's never wise to rely on defaults being set to a particular value, IMHO, whether it's for date formats, currency formats, optimiser modes or whatever. You should always set the value of date format that you need, in the server, the client, or the application.

In particular, never rely on defaults when converting date or numeric data types for display purposes, because a single change to the database can break your application. Always use an explicit conversion format. For years I worked on Oracle systems where the out of the box default date display format was MM/DD/RR, which drove me nuts but at least forced me to always use an explicit conversion.

Since {dplyr} v1.0.0 (May 2020) there is the new slice_* syntax which supersedes top_n().

See also https://dplyr.tidyverse.org/reference/slice.html.

library(tidyverse)

ID    <- c(1,1,1,2,2,2,2,3,3)
Value <- c(2,3,5,2,5,8,17,3,5)
Event <- c(1,1,2,1,2,1,2,2,2)

group <- data.frame(Subject=ID, pt=Value, Event=Event)

group %>% 
  group_by(Subject) %>% 
  slice_max(pt)
#> # A tibble: 3 x 3
#> # Groups:   Subject [3]
#>   Subject    pt Event
#>     <dbl> <dbl> <dbl>
#> 1       1     5     2

Here is my code. The idea is that ImageView gets color filter when user touches it, and color filter is removed when user stops touching it.

Martin Booka Weser, András, Ah Lam, altosh, solution doesn't work when ImageView has also onClickEvent. worawee.s and kcoppock (with ImageButton) solution requires background, which has no sense when ImageView is not transparent.

This one is extension of AZ_ idea about color filter.

class PressedEffectStateListDrawable extends StateListDrawable {

    private int selectionColor;

    public PressedEffectStateListDrawable(Drawable drawable, int selectionColor) {
        super();
        this.selectionColor = selectionColor;
        addState(new int[] { android.R.attr.state_pressed }, drawable);
        addState(new int[] {}, drawable);
    }

    @Override
    protected boolean onStateChange(int[] states) {
        boolean isStatePressedInArray = false;
        for (int state : states) {
            if (state == android.R.attr.state_pressed) {
                isStatePressedInArray = true;
            }
        }
        if (isStatePressedInArray) {
            super.setColorFilter(selectionColor, PorterDuff.Mode.MULTIPLY);
        } else {
            super.clearColorFilter();
        }
        return super.onStateChange(states);
    }

    @Override
    public boolean isStateful() {
        return true;
    }
}

usage:

Drawable drawable = new FastBitmapDrawable(bm);
imageView.setImageDrawable(new PressedEffectStateListDrawable(drawable, 0xFF33b5e5));

  $('[data-poload]').popover({
    content: function(){
      var div_id =  "tmp-id-" + $.now();
      return details_in_popup($(this).data('poload'), div_id, $(this));
    },
    delay: 500,

    trigger: 'hover',
    html:true
  });

  function details_in_popup(link, div_id, el){
      $.ajax({
          url: link,
          cache:true,
          success: function(response){
              $('#'+div_id).html(response);
              el.data('bs.popover').options.content = response;
          }
      });
      return '<div id="'+ div_id +'"><i class="fa fa-spinner fa-spin"></i></div>';
  }   

Ajax content is loaded once! see el.data('bs.popover').options.content = response;

Using final in a method parameter has nothing to do with what happens to the argument on the caller side. It is only meant to mark it as not changing inside that method. As I try to adopt a more functional programming style, I kind of see the value in that.

Enable Multidex through build.gradle of your app module

multiDexEnabled true

Same as below -

android {
    compileSdkVersion 27
    defaultConfig {
        applicationId "com.xx.xxx"
        minSdkVersion 15
        targetSdkVersion 27
        versionCode 1
        versionName "1.0"
        multiDexEnabled true //Add this
        testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner"
    }
    buildTypes {
        release {
            shrinkResources true
            minifyEnabled true
            proguardFiles getDefaultProguardFile('proguard-android-optimize.txt'), 'proguard-rules.pro'
        }
    }
}

Then follow below steps -

1. From the Build menu -> press the Clean Project button.
2. When task completed, press the Rebuild Project button from the Build menu.
3. From menu File -> Invalidate cashes / Restart

compile is now deprecated so it's better to use implementation or api

I'm not an expert. But you can try

git fsck --full --no-reflogs | grep commit

to find the HEAD commit of deleted branch and get them back.

This question may be a little old, but because I think the "right" answer here is only one way which can lead to some issues hidden Issues later in your code. Even if there is a little Controversy, Checked Exceptions exist for a reason.

The most elegant way in my opinion can you find was given by Misha here Aggregate runtime exceptions in Java 8 streams by just performing the actions in "futures". So you can run all the working parts and collect not working Exceptions as a single one. Otherwise you could collect them all in a List and process them later.

A similar approach comes from Benji Weber. He suggests to create an own type to collect working and not working parts.

Depending on what you really want to achieve a simple mapping between the input values and Output Values occurred Exceptions may also work for you.

If you don't like any of these ways consider using (depending on the Original Exception) at least an own exception.

Disclaimer: This is not a solution, it is more of a hack to test out something. User-defined functions cannot be used to perform actions that modify the database state.

I found one way to make insert or update using sqlcmd.exe so you need just to replace the code inside @sql variable.

CREATE FUNCTION [dbo].[_tmp_func](@orderID NVARCHAR(50))
RETURNS INT
AS
BEGIN
DECLARE @sql varchar(4000), @cmd varchar(4000)
SELECT @sql = 'INSERT INTO _ord (ord_Code) VALUES (''' + @orderID + ''') '
SELECT @cmd = 'sqlcmd -S ' + @@servername +
              ' -d ' + db_name() + ' -Q "' + @sql + '"'
EXEC master..xp_cmdshell @cmd, 'no_output'
RETURN 1
END

I just had the exact same problem and it turned out to be caused by the fact that 2 projects in the same solution were referencing a different version of the 3rd party library.

Once I corrected all the references everything worked perfectly.

Any reason they can't just click on the tab for your sheet when they want it?

Note for git submodule users - the solutions here will not work for you as-is.

Let's say you have a parent repository called dev, for example, and your submodule repository is called api.

if you are inside of api and you get the error mentioned in this question:

error: bad index file sha1 signature fatal: index file corrupt

The index file will NOT be inside of a .git folder. In fact, the .git won't even be a folder - it will will be a text document with the location of the real .git data for this repository. Likely something like this:

~/dev/api $ cat .git gitdir: ../.git/modules/api

So, instead of rm -f .git/index, you will need to do this:

rm -f ../.git/modules/api/index git reset

or, more generally,

rm -f ../.git/modules/INSERT_YOUR_REPO_NAME_HERE/index git reset

Here is the modified script which i took from http://www.foliotek.com/devblog/sql-server-optimization-with-index-rebuilding which i found useful to post here. Although it uses a cursor and i know what is the main problem with cursors it can be easily converted to a cursor-less version.

API vs Web Service

Just pasted the summary of the linked article:

Summary:

1. All Web services are APIs but all APIs are not Web services.

2. Web services might not perform all the operations that an API would perform.

3. A Web service uses only three styles of use: SOAP, REST and XML-RPC for communication whereas API may use any style for communication.

4. A Web service always needs a network for its operation whereas an API doesn’t need a network for its operation.

5. An API facilitates interfacing directly with an application whereas a Web service is a ...

See the above link for the complete answer.

You can also bind your SelectedIndex to a property in your ViewModel and manipulate your SelectedItem that way:

        public int SelectedIndex
        {
            get { return _selectedIndex; }
            set
            {
                _selectedIndex = value;
                OnPropertyChanged();
            }    
        }

And in your XAML:

<ComboBox SelectedIndex="{Binding SelectedIndex,Mode=TwoWay}" ... >

    <br>
    <%String id = request.getParameter("track_id");%>
       <%if (id.length() == 0) {%>
    <b><h1>Please Enter Tracking ID</h1></b>
    <% } else {%>
    <div class="container">
        <table border="1" class="table" >
            <thead>
                <tr class="warning" >
                    <td ><h4>Track ID</h4></td>
                    <td><h4>Source</h4></td>
                    <td><h4>Destination</h4></td>
                    <td><h4>Current Status</h4></td>

                </tr>
            </thead>
            <%
                try {
                    connection = DriverManager.getConnection(connectionUrl + database, userid, password);
                    statement = connection.createStatement();
                    String sql = "select * from track where track_id="+ id;
                    resultSet = statement.executeQuery(sql);
                    while (resultSet.next()) {
            %>
            <tr class="info">
                <td><%=resultSet.getString("track_id")%></td>
                <td><%=resultSet.getString("source")%></td>
                <td><%=resultSet.getString("destination")%></td>
                <td><%=resultSet.getString("status")%></td>
            </tr>
            <%
                    }
                    connection.close();
                } catch (Exception e) {
                    e.printStackTrace();
                }
            %>
        </table>

        <%}%>

I dont know why you havent marked on of these gr8 answers... here is another option which would enable you and anyone else visiting to control transition speed and pause time

JAVASCRIPT

$(function () {

    /* SET PARAMETERS */
    var change_img_time     = 5000; 
    var transition_speed    = 100;

    var simple_slideshow    = $("#exampleSlider"),
        listItems           = simple_slideshow.children('li'),
        listLen             = listItems.length,
        i                   = 0,

        changeList = function () {

            listItems.eq(i).fadeOut(transition_speed, function () {
                i += 1;
                if (i === listLen) {
                    i = 0;
                }
                listItems.eq(i).fadeIn(transition_speed);
            });

        };

    listItems.not(':first').hide();
    setInterval(changeList, change_img_time);

});

.

From the oracle documentation, the below query explains it better

INSERT INTO tbl_temp2 (fld_id)
SELECT tbl_temp1.fld_order_id
FROM tbl_temp1 WHERE tbl_temp1.fld_order_id > 100;

You can read this link

Your query would be as follows

//just the concept    
    INSERT INTO quotedb
    (COLUMN_NAMES) //seperated by comma
    SELECT COLUMN_NAMES FROM tickerdb,quotedb WHERE quotedb.ticker = tickerdb.ticker

Note: Make sure the columns in insert and select are in right position as per your requirement

Hope this helps!

If you have an unknown number of lists of the same length, you can use the below function.

Here the *args accepts a variable number of list arguments (but only sums the same number of elements in each). The * is used again to unpack the elements in each of the lists.

def sum_lists(*args):
    return list(map(sum, zip(*args)))

a = [1,2,3]
b = [1,2,3]  

sum_lists(a,b)

Output:

[2, 4, 6]

Or with 3 lists

sum_lists([5,5,5,5,5], [10,10,10,10,10], [4,4,4,4,4])

Output:

[19, 19, 19, 19, 19]

arrowdodger's answer is correct and preferred on many occasions. I would simply like to add an alternative to his answer:

You could add an "imported" library target, instead of a link-directory. Something like:

# Your-external "mylib", add GLOBAL if the imported library is located in directories above the current.
add_library( mylib SHARED IMPORTED )
# You can define two import-locations: one for debug and one for release.
set_target_properties( mylib PROPERTIES IMPORTED_LOCATION ${CMAKE_BINARY_DIR}/res/mylib.so )

And then link as if this library was built by your project:

TARGET_LINK_LIBRARIES(GLBall mylib)

Such an approach would give you a little more flexibility: Take a look at the add_library( ) command and the many target-properties related to imported libraries.

I do not know if this will solve your problem with "updated versions of libs".

A snippet out of the MSDN:

'The following code sample shows how to create a DateTimePicker that enables users to choose a time only.'

timePicker = new DateTimePicker();
timePicker.Format = DateTimePickerFormat.Time;
timePicker.ShowUpDown = true;

With the unobtrusive way:

• You don't have to call the validate() method.
• You specify requirements using data attributes (data-val, data-val-required, etc.)

Jquery Validate Example:

<input type="text" name="email" class="required">
<script>
        $(function () {
            $("form").validate();
        });
</script>

Jquery Validate Unobtrusive Example:

<input type="text" name="email" data-val="true" 
data-val-required="This field is required.">  

<div class="validation-summary-valid" data-valmsg-summary="true">
    <ul><li style="display:none"></li></ul>
</div>

Unfortunately:

• It seems you can not reference a single item from an array in values/arrays.xml with XML. Of course you can in Java, but not XML. There's no information on doing so in the Android developer reference, and I could not find any anywhere else.

• It seems you can't use an array as a key in the preferences layout. Each key has to be a single value with it's own key name.

What I want to accomplish: I want to be able to loop through the 17 preferences, check if the item is checked, and if it is, load the string from the string array for that preference name.

Here's the code I was hoping would complete this task:

SharedPreferences prefs = PreferenceManager.getDefaultSharedPreferences(getBaseContext());  
ArrayAdapter<String> itemsArrayList = new ArrayAdapter<String>(getBaseContext(),   android.R.layout.simple_list_item_1);  
String[] itemNames = getResources().getStringArray(R.array.itemNames_array);  


for (int i = 0; i < 16; i++) {  
    if (prefs.getBoolean("itemKey[i]", true)) {  
        itemsArrayList.add(itemNames[i]);  
    }  
} 

What I did:

• I set a single string for each of the items, and referenced the single strings in the . I use the single string reference for the preferences layout checkbox titles, and the array for my loop.

• To loop through the preferences, I just named the keys like key1, key2, key3, etc. Since you reference a key with a string, you have the option to "build" the key name at runtime.

Here's the new code:

for (int i = 0; i < 16; i++) {  
        if (prefs.getBoolean("itemKey" + String.valueOf(i), true)) {  
        itemsArrayList.add(itemNames[i]);  
    }  
}

you can use this package : toast

add this line to your dependencies

toast: ^0.1.5

then use it like this :

import 'package:toast/toast.dart';
Toast.show("Toast plugin app", context, duration: Toast.LENGTH_SHORT, gravity:  Toast.BOTTOM);

For the sake of completeness, I wanted to add that the definition of the '+' operator can be found in the JLS SE8 15.18.1:

If only one operand expression is of type String, then string conversion (§5.1.11) is performed on the other operand to produce a string at run time.

The result of string concatenation is a reference to a String object that is the concatenation of the two operand strings. The characters of the left-hand operand precede the characters of the right-hand operand in the newly created string.

The String object is newly created (§12.5) unless the expression is a constant expression (§15.28).

About the implementation the JLS says the following:

An implementation may choose to perform conversion and concatenation in one step to avoid creating and then discarding an intermediate String object. To increase the performance of repeated string concatenation, a Java compiler may use the StringBuffer class or a similar technique to reduce the number of intermediate String objects that are created by evaluation of an expression.

For primitive types, an implementation may also optimize away the creation of a wrapper object by converting directly from a primitive type to a string.

So judging from the 'a Java compiler may use the StringBuffer class or a similar technique to reduce', different compilers could produce different byte-code.

This is really simple , just add this in web.config

<system.webServer>
  <httpProtocol>
    <customHeaders>
      <add name="Access-Control-Allow-Origin" value="http://localhost" />
      <add name="Access-Control-Allow-Headers" value="X-AspNet-Version,X-Powered-By,Date,Server,Accept,Accept-Encoding,Accept-Language,Cache-Control,Connection,Content-Length,Content-Type,Host,Origin,Pragma,Referer,User-Agent" />
      <add name="Access-Control-Allow-Methods" value="GET, PUT, POST, DELETE, OPTIONS" />
      <add name="Access-Control-Max-Age" value="1000" />
    </customHeaders>
  </httpProtocol>
</system.webServer>

In Origin put all domains that have access to your web server, in headers put all possible headers that any ajax http request can use, in methods put all methods that you allow on your server

regards :)

You could put all of your code under one namespace like this:

var namespace = {};

namespace.someClassObj = {};

delete namespace.someClassObj;

Using the delete keyword will delete the reference to the property, but on the low level the JavaScript garbage collector (GC) will get more information about which objects to be reclaimed.

You could also use Chrome Developer Tools to get a memory profile of your app, and which objects in your app are needing to be scaled down.

Look at the yesno helper

Eg:

{{ myValue|yesno:"itwasTrue,itWasFalse,itWasNone" }}

A solution with service and awk that takes in a comma-delimited list of service names.

First it's probably a good bet you'll need root privileges to do what you want. If you don't need to check then you can remove that part.

#!/usr/bin/env bash

# First parameter is a comma-delimited string of service names i.e. service1,service2,service3
SERVICES=$1

ALL_SERVICES_STARTED=true

if [ $EUID -ne 0 ]; then
  if [ "$(id -u)" != "0" ]; then
    echo "root privileges are required" 1>&2
    exit 1
  fi
  exit 1
fi

for service in ${SERVICES//,/ }
do
    STATUS=$(service ${service} status | awk '{print $2}')

    if [ "${STATUS}" != "started" ]; then
        echo "${service} not started"
        ALL_SERVICES_STARTED=false
    fi
done

if ${ALL_SERVICES_STARTED} ; then
    echo "All services started"
    exit 0
else
    echo "Check Failed"
    exit 1
fi

SELECT DISTINCT groups.id, 
       (SELECT COUNT(*) FROM group_members
        WHERE member_id = groups.id) AS memberCount
FROM groups

All current answers provide the offset differece at current time, not at a given date.

moment(date).utcOffset() returns the time difference in minutes between browser time and UTC at the date passed as argument (or today, if no date passed).

Here's a function to parse correct offset at the picked date:

function getUtcOffset(date) {
  return moment(date)
    .subtract(
      moment(date).utcOffset(), 
      'minutes')
    .utc()
}

DON'T use (.|[\r\n]) instead of . for multiline matching.

DO use [\s\S] instead of . for multiline matching

Also, avoid greediness where not needed by using *? or +? quantifier instead of * or +. This can have a huge performance impact.

See the benchmark I have made: http://jsperf.com/javascript-multiline-regexp-workarounds

Using [^]: fastest
Using [\s\S]: 0.83% slower
Using (.|\r|\n): 96% slower
Using (.|[\r\n]): 96% slower

NB: You can also use [^] but it is deprecated in the below comment.

You can use pyplot.matshow() from matplotlib:

import matplotlib.pyplot as plt

plt.matshow(dataframe.corr())
plt.show()

Edit:

In the comments was a request for how to change the axis tick labels. Here's a deluxe version that is drawn on a bigger figure size, has axis labels to match the dataframe, and a colorbar legend to interpret the color scale.

I'm including how to adjust the size and rotation of the labels, and I'm using a figure ratio that makes the colorbar and the main figure come out the same height.

EDIT 2: As the df.corr() method ignores non-numerical columns, .select_dtypes(['number']) should be used when defining the x and y labels to avoid an unwanted shift of the labels (included in the code below).

f = plt.figure(figsize=(19, 15))
plt.matshow(df.corr(), fignum=f.number)
plt.xticks(range(df.select_dtypes(['number']).shape[1]), df.select_dtypes(['number']).columns, fontsize=14, rotation=45)
plt.yticks(range(df.select_dtypes(['number']).shape[1]), df.select_dtypes(['number']).columns, fontsize=14)
cb = plt.colorbar()
cb.ax.tick_params(labelsize=14)
plt.title('Correlation Matrix', fontsize=16);

In my case, it's related to the Toggle Vrapper Icon in the Eclipse.

If you are getting the bold black cursor, then the icon must be enabled. So, click on the Toggle Vrapper Icon to disable. It's located in the Eclipse's Toolbar. Please see the attached image for the clarity.

Should just be this:

var jobject = JsonConvert.DeserializeObject<RootObject>(jsonstring);

You can paste the json string to here: http://json2csharp.com/ to check your classes are correct.

While searching I got the following query which does the job with one assumption(query execution time >6 seconds)

SELECT username, sql_text, sofar, totalwork, units

FROM v$sql,v$session_longops

WHERE sql_address = address AND sql_hash_value = hash_value

ORDER BY address, hash_value, child_number;

I think above query will list the details for current user.

Comments are welcome!!

No need to go with GSON for this; Jackson can do either plain Maps/Lists:

ObjectMapper mapper = new ObjectMapper();
Map<String,Object> map = mapper.readValue(json, Map.class);

or more convenient JSON Tree:

JsonNode rootNode = mapper.readTree(json);

By the way, there is no reason why you could not actually create Java classes and do it (IMO) more conveniently:

public class Library {
  @JsonProperty("libraryname")
  public String name;

  @JsonProperty("mymusic")
  public List<Song> songs;
}
public class Song {
  @JsonProperty("Artist Name") public String artistName;
  @JsonProperty("Song Name") public String songName;
}

Library lib = mapper.readValue(jsonString, Library.class);

As of mid-2019

1. type your query in the top left search box
2. hit Enter
3. click "Commits"

Screenshot:

Here is how I figured it out. I am behind corporate firewall too.

Go to Chrome or your Internet Settings by clicking the wrench in Chrome --> Settings --> Under the Hood --> Network --> Change Proxy Settings

Click on LAN Settings and then Advanced. Copy the proxy server address and port.

Mostly the connection refused link occurs when trying to download SDK packages through Eclipse.

Navigate to the SDK Manager.exe and double click on it. Once it starts click on Tools --> Options and then enter the proxy server address and the Port #

Check the checkbox force https:// to http:// That's it your SDK Manager will now be able to download packages from google remote site without any issue even from behind a firewall.

I am on Windows by the way. Tried everything and this works great.

I think you mean cast(floor(cast(getdate()as float))as datetime)

real is only 32-bits, and could lose some information

This is fastest cast(cast(getdate()+x-0.5 as int)as datetime)

...though only about 10% faster(about 0.49 microseconds CPU vs. 0.58)

This was recommended, and takes the same time in my test just now: DATEADD(dd, DATEDIFF(dd, 0, getdate()), 0)

In SQL 2008, the SQL CLR function is about 5 times faster than using a SQL function would be, at 1.35 microseconds versus 6.5 microsections, indicating much lower function-call overhead for a SQL CLR function versus a simple SQL UDF.

In SQL 2005, the SQL CLR function is 16 times faster, per my testing, versus this slow function:

create function dateonly (  @dt datetime )
returns datetime
as
begin
return cast(floor(cast(@dt as float))as int)
end

If you need just positive integer numbers and don't need leading zeros (e.g. "0001234" or "00"):

var reg = /^(?:[1-9]\d*|\d)$/;

try this function...

I followed the top answer and started looking at yahoo finance. Their API can be accessed a number of different ways, but I found a nice reference for getting stock info as a CSV here: http://www.jarloo.com/

Using that I wrote this script. I'm not really a ruby guy but this might help you hack something together. I haven't come up with variable names for all the fields yahoo offers yet, so you can fill those in if you need them.

Here's the usage

AllData = loadStockInfo(TICKERS_SP500, allParameters())

SpecificData = loadStockInfo("GOOG,CIK", "ask,dps")

loadStockInfo returns a hash, such that SpecificData["GOOG"]["name"] is "Google Inc."

edit the code for 'select' as below for checking for a 0 or null value selection from select list

case 'select':
var options = $("option:selected", element);
return (options[0].value != 0 && options.length > 0 && options[0].value != '') && (element.type == "select-multiple" || ($.browser.msie && !(options[0].attributes['value'].specified) ? options[0].text : options[0].value).length > 0);

Change your append calls to say

...append(iter->first)

and

... append(iter->second)

Additionally, the line

std::string* strToReturn = new std::string("");

allocates a string on the heap. If you intend to actually return a pointer to this dynamically allocated string, the return should be changed to std::string*.

Alternatively, if you don't want to worry about managing that object on the heap, change the local declaration to

std::string strToReturn("");

and change the 'append' calls to use reference syntax...

strToReturn.append(...)

instead of

strToReturn->append(...)

Be aware that this will construct the string on the stack, then copy it into the return variable. This has performance implications.

This code works for me

The promise will always log pending as long as its results are not resolved yet. You must call .then on the promise to capture the results regardless of the promise state (resolved or still pending):

let AuthUser = function(data) {
  return google.login(data.username, data.password).then(token => { return token } )
}

let userToken = AuthUser(data)
console.log(userToken) // Promise { <pending> }

userToken.then(function(result) {
   console.log(result) // "Some User token"
})

Why is that?

Promises are forward direction only; You can only resolve them once. The resolved value of a Promise is passed to its .then or .catch methods.

Details

According to the Promises/A+ spec:

The promise resolution procedure is an abstract operation taking as input a promise and a value, which we denote as [[Resolve]](promise, x). If x is a thenable, it attempts to make promise adopt the state of x, under the assumption that x behaves at least somewhat like a promise. Otherwise, it fulfills promise with the value x.

This treatment of thenables allows promise implementations to interoperate, as long as they expose a Promises/A+-compliant then method. It also allows Promises/A+ implementations to “assimilate” nonconformant implementations with reasonable then methods.

This spec is a little hard to parse, so let's break it down. The rule is:

If the function in the .then handler returns a value, then the Promise resolves with that value. If the handler returns another Promise, then the original Promise resolves with the resolved value of the chained Promise. The next .then handler will always contain the resolved value of the chained promise returned in the preceding .then.

The way it actually works is described below in more detail:

1. The return of the .then function will be the resolved value of the promise.

function initPromise() {
  return new Promise(function(res, rej) {
    res("initResolve");
  })
}

initPromise()
  .then(function(result) {
    console.log(result); // "initResolve"
    return "normalReturn";
  })
  .then(function(result) {
    console.log(result); // "normalReturn"
  });

2. If the .then function returns a Promise, then the resolved value of that chained promise is passed to the following .then.

function initPromise() {
  return new Promise(function(res, rej) {
    res("initResolve");
  })
}

initPromise()
  .then(function(result) {
    console.log(result); // "initResolve"
    return new Promise(function(resolve, reject) {
       setTimeout(function() {
          resolve("secondPromise");
       }, 1000)
    })
  })
  .then(function(result) {
    console.log(result); // "secondPromise"
  });

Connection timeouts (assuming a local network and several client machines) typically result from

a) some kind of firewall on the way that simply eats the packets without telling the sender things like "No Route to host"

b) packet loss due to wrong network configuration or line overload

c) too many requests overloading the server

d) a small number of simultaneously available threads/processes on the server which leads to all of them being taken. This happens especially with requests that take a long time to run and may combine with c).

Hope this helps.

Looks like there is an issue with the code you posted. Your function to display the T&C is referencing the wrong div id. You should consider assigning the showTOC function to the onclick attribute once the document is loaded as well:

$(document).ready({
    $('a.TOClink').click(function(){
        showTOC();
    });
});

function showTOC() {
    $('#example').dialog({modal:true});
}

A more concise example which accomplishes the desired effect using the jQuery UI dialog is:

   <div id="terms" style="display:none;">
       Lorem ipsum dolor sit amet, consectetur adipisicing elit, sed do eiusmod tempor incididunt ut labore et dolore magna aliqua. Ut enim ad minim veniam, quis nostrud exercitation ullamco laboris nisi ut aliquip ex ea commodo consequat. Duis aute irure dolor in reprehenderit in voluptate velit esse cillum dolore eu fugiat nulla pariatur. Excepteur sint occaecat cupidatat non proident, sunt in culpa qui officia deserunt mollit anim id est laborum.
   </div>
   <a id="showTerms" href="#">Show Terms &amp; Conditions</a>      
   <script type="text/javascript">
       $(document).ready(function(){
           $('#showTerms').click(function(){
               $('#terms').dialog({modal:true});   
           });
       });

You want to focus on immutability in Scala generally by eliminating any vars. Readability is still important for your fellow man so:

Try:

scala> val list = for(i <- 1 to 10) yield i
list: scala.collection.immutable.IndexedSeq[Int] = Vector(1, 2, 3, 4, 5, 6, 7, 8, 9, 10)

You probably don't even need to convert to a list in most cases :)

The indexed seq will have everything you need:

That is, you can now work on that IndexedSeq:

scala> list.foldLeft(0)(_+_)
res0: Int = 55

Just right click on that column and select properties and write getdate()in Default value or binding.like image:

If you want do it in CodeFirst in EF you should add this attributes befor of your column definition:

[Databasegenerated(Databaseoption.computed)]

this attributes can found in System.ComponentModel.Dataannotion.Schema.

In my opinion first one is better:))

I realized a Open Source library on GitHub CircularProgressBar that does exactly what you want the simplest way possible:

USAGE

To make a circular ProgressBar add CircularProgressBar in your layout XML and add CircularProgressBar library in your projector or you can also grab it via Gradle:

compile 'com.mikhaellopez:circularprogressbar:1.0.0'

XML

<com.mikhaellopez.circularprogressbar.CircularProgressBar
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    app:background_progressbar_color="#FFCDD2"
    app:background_progressbar_width="5dp"
    app:progressbar_color="#F44336"
    app:progressbar_width="10dp" />

You must use the following properties in your XML to change your CircularProgressBar.

Properties:

• app:progress (integer) >> default 0
• app:progressbar_color (color) >> default BLACK
• app:background_progressbar_color (color) >> default GRAY
• app:progressbar_width (dimension) >> default 7dp
• app:background_progressbar_width (dimension) >> default 3dp

JAVA

CircularProgressBar circularProgressBar = (CircularProgressBar)findViewById(R.id.yourCircularProgressbar);
circularProgressBar.setColor(ContextCompat.getColor(this, R.color.progressBarColor));
circularProgressBar.setBackgroundColor(ContextCompat.getColor(this, R.color.backgroundProgressBarColor));
circularProgressBar.setProgressBarWidth(getResources().getDimension(R.dimen.progressBarWidth));
circularProgressBar.setBackgroundProgressBarWidth(getResources().getDimension(R.dimen.backgroundProgressBarWidth));
int animationDuration = 2500; // 2500ms = 2,5s
circularProgressBar.setProgressWithAnimation(65, animationDuration); // Default duration = 1500ms

Fork or Download this library here >> https://github.com/lopspower/CircularProgressBar

To install Python package from github, you need to clone that repository.

There are many answers, but you should just be able to keep it simple. Make sure you know what port SSH is listening on, and define it. Here is what I just used to replicate your problem.

scp -P 12222 file.7z [email protected]:/home/user/Downloads It worked out well.

Notice: I do update this answer as I find better solutions. I also keep the old answers for future reference as long as they remain related. Latest and best answer comes first.

Better answer:

Directives in angularjs are very powerful, but it takes time to comprehend which processes lie behind them.

While creating directives, angularjs allows you to create an isolated scope with some bindings to the parent scope. These bindings are specified by the attribute you attach the element in DOM and how you define scope property in the directive definition object.

There are 3 types of binding options which you can define in scope and you write those as prefixes related attribute.

angular.module("myApp", []).directive("myDirective", function () {
    return {
        restrict: "A",
        scope: {
            text: "@myText",
            twoWayBind: "=myTwoWayBind",
            oneWayBind: "&myOneWayBind"
        }
    };
}).controller("myController", function ($scope) {
    $scope.foo = {name: "Umur"};
    $scope.bar = "qwe";
});

HTML

<div ng-controller="myController">
    <div my-directive my-text="hello {{ bar }}" my-two-way-bind="foo" my-one-way-bind="bar">
    </div>
</div>

In that case, in the scope of directive (whether it's in linking function or controller), we can access these properties like this:

/* Directive scope */

in: $scope.text
out: "hello qwe"
// this would automatically update the changes of value in digest
// this is always string as dom attributes values are always strings

in: $scope.twoWayBind
out: {name:"Umur"}
// this would automatically update the changes of value in digest
// changes in this will be reflected in parent scope

// in directive's scope
in: $scope.twoWayBind.name = "John"

//in parent scope
in: $scope.foo.name
out: "John"


in: $scope.oneWayBind() // notice the function call, this binding is read only
out: "qwe"
// any changes here will not reflect in parent, as this only a getter .

"Still OK" Answer:

Since this answer got accepted, but has some issues, I'm going to update it to a better one. Apparently, $parse is a service which does not lie in properties of the current scope, which means it only takes angular expressions and cannot reach scope. {{,}} expressions are compiled while angularjs initiating which means when we try to access them in our directives postlink method, they are already compiled. ({{1+1}} is 2 in directive already).

This is how you would want to use:

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

myApp.directive('myDirective', function ($parse) {
    return function (scope, element, attr) {
        element.val("value=" + $parse(attr.myDirective)(scope));
    };
});

function MyCtrl($scope) {
    $scope.aaa = 3432;
}?

.

<div ng-controller="MyCtrl">
    <input my-directive="123">
    <input my-directive="1+1">
    <input my-directive="'1+1'">
    <input my-directive="aaa">
</div>????????

One thing you should notice here is that, if you want set the value string, you should wrap it in quotes. (See 3rd input)

Here is the fiddle to play with: http://jsfiddle.net/neuTA/6/

Old Answer:

I'm not removing this for folks who can be misled like me, note that using $eval is perfectly fine the correct way to do it, but $parse has a different behavior, you probably won't need this to use in most of the cases.

The way to do it is, once again, using scope.$eval. Not only it compiles the angular expression, it has also access to the current scope's properties.

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

myApp.directive('myDirective', function () {
    return function (scope, element, attr) {
        element.val("value = "+ scope.$eval(attr.value));
    }
});

function MyCtrl($scope) {
   
}?

What you are missing was $eval.

http://docs.angularjs.org/api/ng.$rootScope.Scope#$eval

Executes the expression on the current scope returning the result. Any exceptions in the expression are propagated (uncaught). This is useful when evaluating angular expressions.

I solved it through googling:

var ObjectId = require('mongoose').Types.ObjectId;
var objId = new ObjectId( (param.length < 12) ? "123456789012" : param );
// You should make string 'param' as ObjectId type. To avoid exception, 
// the 'param' must consist of more than 12 characters.

User.find( { $or:[ {'_id':objId}, {'name':param}, {'nickname':param} ]}, 
  function(err,docs){
    if(!err) res.send(docs);
});

You can use .filter() method of the Array object:

var filtered = workItems.filter(function(element) {
   // Create an array using `.split()` method
   var cats = element.category.split(' ');

   // Filter the returned array based on specified filters
   // If the length of the returned filtered array is equal to
   // length of the filters array the element should be returned  
   return cats.filter(function(cat) {
       return filtersArray.indexOf(cat) > -1;
   }).length === filtersArray.length;
});

http://jsfiddle.net/6RBnB/

Some old browsers like IE8 doesn't support .filter() method of the Array object, if you are using jQuery you can use .filter() method of jQuery object.

jQuery version:

var filtered = $(workItems).filter(function(i, element) {
   var cats = element.category.split(' ');

    return $(cats).filter(function(_, cat) {
       return $.inArray(cat, filtersArray) > -1;
    }).length === filtersArray.length;
});

Although officially there is no limit specified by RFC 2616, many security protocols and recommendations state that maxQueryStrings on a server should be set to a maximum character limit of 1024. While the entire URL, including the querystring, should be set to a max of 2048 characters. This is to prevent the Slow HTTP Request DDOS vulnerability on a web server. This typically shows up as a vulnerability on the Qualys Web Application Scanner and other security scanners.

Please see the below example code for Windows IIS Servers with Web.config:

<system.webServer>
<security>
    <requestFiltering>
        <requestLimits maxQueryString="1024" maxUrl="2048">
           <headerLimits>
              <add header="Content-type" sizeLimit="100" />
           </headerLimits>
        </requestLimits>
     </requestFiltering>
</security>
</system.webServer>

This would also work on a server level using machine.config.

Note: Limiting query string and URL length may not completely prevent Slow HTTP Requests DDOS attack but it is one step you can take to prevent it.

I have explained use of various CURL options required for CURL PROXY.

$url = 'http://dynupdate.no-ip.com/ip.php';
$proxy = '127.0.0.1:8888';
$proxyauth = 'user:password';

$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, $url);         // URL for CURL call
curl_setopt($ch, CURLOPT_PROXY, $proxy);     // PROXY details with port
curl_setopt($ch, CURLOPT_PROXYUSERPWD, $proxyauth);   // Use if proxy have username and password
curl_setopt($ch, CURLOPT_PROXYTYPE, CURLPROXY_SOCKS5); // If expected to call with specific PROXY type
curl_setopt($ch, CURLOPT_FOLLOWLOCATION, 1);  // If url has redirects then go to the final redirected URL.
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 0);  // Do not outputting it out directly on screen.
curl_setopt($ch, CURLOPT_HEADER, 1);   // If you want Header information of response else make 0
$curl_scraped_page = curl_exec($ch);
curl_close($ch);

echo $curl_scraped_page;

Use the formaction HTML attribute (5th line):

You are pretty confused my friend. There are no LOOPS in SQL, only in PL/SQL. Here's a few examples based on existing Oracle table - copy/paste to see results:

-- Numeric FOR loop --
set serveroutput on -->> do not use in TOAD --
DECLARE
  k NUMBER:= 0;
BEGIN
  FOR i IN 1..10 LOOP
    k:= k+1;
    dbms_output.put_line(i||' '||k);
 END LOOP;
END;
/

-- Cursor FOR loop --
set serveroutput on
DECLARE
   CURSOR c1 IS SELECT * FROM scott.emp;
   i NUMBER:= 0;
BEGIN
  FOR e_rec IN c1 LOOP
  i:= i+1;
    dbms_output.put_line(i||chr(9)||e_rec.empno||chr(9)||e_rec.ename);
  END LOOP;
END;
/

-- SQL example to generate 10 rows --

I know this question is quite old, but I was looking for a solution to this problem too. The accepted solution is for WinForms not WPF which I think many who come here are looking for.

For anyone looking for a WPF solution, here is a great approach (via Oskar's answer here):

private void myListBox_MouseDoubleClick(object sender, MouseButtonEventArgs e)
{
    DependencyObject obj = (DependencyObject)e.OriginalSource;

    while (obj != null && obj != myListBox)
    {
        if (obj.GetType() == typeof(ListBoxItem))
        {
             // Do something
             break;
         }
         obj = VisualTreeHelper.GetParent(obj);
    }
}

Basically, you walk up the VisualTree until you've either found a parent item that is a ListBoxItem, or you ascend up to the actual ListBox (and therefore did not click a ListBoxItem).

NUMBER (precision, scale) means precision number of total digits, of which scale digits are right of the decimal point.

NUMBER(2,2) in other words means a number with 2 digits, both of which are decimals. You may mean to use NUMBER(4,2) to get 4 digits, of which 2 are decimals. Currently you can just insert values with a zero integer part.

More info at the Oracle docs.

I just copied the jre folder to whatever path the message tells me it was missing at, and solved it.

IIUC, if you make your (unfortunately named) List into an ndarray, you can simply index into it naturally.

>>> import numpy as np
>>> m = np.arange(16)*10
>>> m[df.A]
array([  0,  40,  50,  60, 150, 150, 140, 130])
>>> df["D"] = m[df.A]
>>> df
    A   B   C    D
0   0 NaN NaN    0
1   4 NaN NaN   40
2   5 NaN NaN   50
3   6 NaN NaN   60
4  15 NaN NaN  150
5  15 NaN NaN  150
6  14 NaN NaN  140
7  13 NaN NaN  130

Here I built a new m, but if you use m = np.asarray(List), the same thing should work: the values in df.A will pick out the appropriate elements of m.

Note that if you're using an old version of numpy, you might have to use m[df.A.values] instead-- in the past, numpy didn't play well with others, and some refactoring in pandas caused some headaches. Things have improved now.

Use the -ExpandProperty flag of Select-Object

$var=Get-WSManInstance -enumerate wmicimv2/win32_process | select -expand Priority

Update to answer the other question:

Note that you can as well just access the property:

$var=(Get-WSManInstance -enumerate wmicimv2/win32_process).Priority

So to get multiple of these into variables:

$var=Get-WSManInstance -enumerate wmicimv2/win32_process
   $prio = $var.Priority
   $pid = $var.ProcessID

There is no show event in js - you need to bind your button either to the click event:

$('#id').on('click', function (e) {

     //your awesome code here

})

Mind that if your button is inside a form, you may prefer to bind the whole form to the submit event.

import java.util.stream.Stream;
import java.nio.file.*;
import java.io.*;

class ReadFile {

 public static void main(String[] args) {

    String filename = "Test.txt";

    try(Stream<String> stream = Files.lines(Paths.get(filename))) {

          stream.forEach(System.out:: println);

    } catch (IOException e) {

        e.printStackTrace();
    }

 }

 }

Just use java 8 Stream.

Use filter:

newlist=filter(lambda x: len(x)>0, oldlist) 

The drawbacks of using filter as pointed out is that it is slower than alternatives; also, lambda is usually costly.

Or you can go for the simplest and the most iterative of all:

# I am assuming listtext is the original list containing (possibly) empty items
for item in listtext:
    if item:
        newlist.append(str(item))
# You can remove str() based on the content of your original list

this is the most intuitive of the methods and does it in decent time.

There are multiple false assumptions you're making here - First, function belong to a class and not to an instance, meaning the actual function involved is the same for any two instances of a class. Second, default parameters are evaluated at compile time and are constant (as in, a constant object reference - if the parameter is a mutable object you can change it). Thus you cannot access self in a default parameter and will never be able to.

I know it sounds weird, but I'm pretty sure this is your problem:

Somewhere in MyGui.java you're using a generic collection without specifying the type. For example if you're using an ArrayList somewhere, you are doing this:

List list = new ArrayList();

When you should be doing this:

List<String> list = new ArrayList<String>();

If you're using MySQL:

SELECT
    DATE(created) AS saledate,
    SUM(amount)
FROM
    Sales
GROUP BY
    saledate

If you're using MS SQL 2008:

SELECT
    CAST(created AS date) AS saledate,
    SUM(amount)
FROM
    Sales
GROUP BY
    CAST(created AS date)

Here is one way to do it:

List<String> duplicates = lst.GroupBy(x => x)
                             .Where(g => g.Count() > 1)
                             .Select(g => g.Key)
                             .ToList();

The GroupBy groups the elements that are the same together, and the Where filters out those that only appear once, leaving you with only the duplicates.

I believe sideshowbarker 's answer here has all the info you need to fix this. If your problem is just No 'Access-Control-Allow-Origin' header is present on the response you're getting, you can set up a CORS proxy to get around this. Way more info on it in the linked answer

not sure if this is the most efficient, but a concise ES6 syntax might be:

let arry = [...htmlCollection] 

Edit: Another one, from Chris_F comment:

let arry = Array.from(htmlCollection)

Would something like this work:

In [7]: df.groupby('dummy').returns.agg({'func1' : lambda x: x.sum(), 'func2' : lambda x: x.prod()})
Out[7]: 
              func2     func1
dummy                        
1     -4.263768e-16 -0.188565

if you need a straight line shadow (like in bottom of toolbar) you can also use gradient xml:

<?xml version="1.0" encoding="utf-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android">
    <gradient
        android:type="linear"
        android:angle="-90"
        android:startColor="#19000000" <!-- black transparent -->
        android:endColor="#00000000" /> <!-- full transparent -->
</shape>

The functional way, with a generator.

def split(path):
    (drive, head) = os.path.splitdrive(path)
    while (head != os.sep):
        (head, tail) = os.path.split(head)
        yield tail

In action:

>>> print([x for x in split(os.path.normpath('/path/to/filename'))])
['filename', 'to', 'path']

Below is the fixed code:

#!/bin/ksh
safeRunCommand() {
  typeset cmnd="$*"
  typeset ret_code

  echo cmnd=$cmnd
  eval $cmnd
  ret_code=$?
  if [ $ret_code != 0 ]; then
    printf "Error : [%d] when executing command: '$cmnd'" $ret_code
    exit $ret_code
  fi
}

command="ls -l | grep p"
safeRunCommand "$command"

Now if you look into this code few things that I changed are:

• use of typeset is not necessary but a good practice. It make cmnd and ret_code local to safeRunCommand
• use of ret_code is not necessary but a good practice to store return code in some variable (and store it ASAP) so that you can use it later like I did in printf "Error : [%d] when executing command: '$command'" $ret_code
• pass the command with quotes surrounding the command like safeRunCommand "$command". If you dont then cmnd will get only the value ls and not ls -l. And it is even more important if your command contains pipes.
• you can use typeset cmnd="$*" instead of typeset cmnd="$1" if you want to keep the spaces. You can try with both depending upon how complex is your command argument.
• eval is used to evaluate so that command containing pipes can work fine

NOTE: Do remember some commands give 1 as return code even though there is no error like grep. If grep found something it will return 0 else 1.

I had tested with KSH/BASH. And it worked fine. Let me know if u face issues running this.

I also encountered the same problem, I was such a solution.

First of all to be clear: provisioning profile must choose "Automatic" to debug.

If provisioning profile is "adhoc", then you can not debug, and can only export the ".ipa" file, import to iTunes for installation.

this is the path to the web root directory c:\wamp\www

you can create different projects by adding different folders to this directory and call them like:

localhost/project1 from browser

this will run the index.html or index.php, lying inside project1

I always come to this question when I hit an error in the test environment and remember, "I've done this before, but I can do it straight in the web.config without having to modify code and re-deploy to the test environment, but it takes 2 changes... what was it again?"

For future reference

How about sapply (not really necessary for this simple case):

newData<- sapply(data, function(x) x^2)

There are a few things which new does that malloc doesn’t:

1. new constructs the object by calling the constructor of that object
2. new doesn’t require typecasting of allocated memory.
3. It doesn’t require an amount of memory to be allocated, rather it requires a number of objects to be constructed.

So, if you use malloc, then you need to do above things explicitly, which is not always practical. Additionally, new can be overloaded but malloc can’t be.

In a word, if you use C++, try to use new as much as possible.

The file is created wherever the root of the python interpreter was started.

Eg, you start python in /home/user/program, then the file "test.py" would be located at /home/user/program/test.py

I have experienced a great example of reproducing such a problem. Maybe my experience will help someone one day.

Short version

Check that your @Embedded Id of container has no possible collisions.

Long version

When Hibernate instantiates collection wrapper, it searches for already instantiated collection by CollectionKey in internal Map.

For Entity with @Embedded id, CollectionKey wraps EmbeddedComponentType and uses @Embedded Id properties for equality checks and hashCode calculation.

So if you have two entities with equal @Embedded Ids, Hibernate will instantiate and put new collection by the first key and will find same collection for the second key. So two entities with same @Embedded Id will be populated with same collection.

Example

Suppose you have Account entity which has lazy set of loans. And Account has @Embedded Id consists of several parts(columns).

@Entity
@Table(schema = "SOME", name = "ACCOUNT")
public class Account {
    @OneToMany(fetch = FetchType.LAZY, mappedBy = "account")
    private Set<Loan> loans;

    @Embedded
    private AccountId accountId;

    ...
}

@Embeddable
public class AccountId {
    @Column(name = "X")
    private Long x;
    
    @Column(name = "BRANCH")
    private String branchId;
    
    @Column(name = "Z")
    private String z;

    ...
}

Then suppose that Account has additional property mapped by @Embedded Id but has relation to other entity Branch.

@ManyToOne(fetch = FetchType.EAGER)
@JoinColumn(name = "BRANCH")
@MapsId("accountId.branchId")
@NotFound(action = NotFoundAction.IGNORE)//Look at this!
private Branch branch;

It could happen that you have no FK for Account to Brunch relation id DB so Account.BRANCH column can have any value not presented in Branch table.

According to @NotFound(action = NotFoundAction.IGNORE) if value is not present in related table, Hibernate will load null value for the property.

If X and Y columns of two Accounts are same(which is fine), but BRANCH is different and not presented in Branch table, hibernate will load null for both and Embedded Ids will be equal.

So two CollectionKey objects will be equal and will have same hashCode for different Accounts.

result = {CollectionKey@34809} "CollectionKey[Account.loans#Account@43deab74]"
 role = "Account.loans"
 key = {Account@26451} 
 keyType = {EmbeddedComponentType@21355} 
 factory = {SessionFactoryImpl@21356} 
 hashCode = 1187125168
 entityMode = {EntityMode@17415} "pojo"

result = {CollectionKey@35653} "CollectionKey[Account.loans#Account@33470aa]"
 role = "Account.loans"
 key = {Account@35225} 
 keyType = {EmbeddedComponentType@21355} 
 factory = {SessionFactoryImpl@21356} 
 hashCode = 1187125168
 entityMode = {EntityMode@17415} "pojo"

Because of this, Hibernate will load same PesistentSet for two entities.

In my case I was having an issue where the table was not being displayed right after the paragraph I inserted it, so I simply changed

\begin{table}[]

to

\begin{table}[ht]

To get the index by value, simply add .index[0] to the end of a query. This will return the index of the first row of the result...

So, applied to your dataframe:

In [1]: a[a['c2'] == 1].index[0]     In [2]: a[a['c1'] > 7].index[0]   
Out[1]: 0                            Out[2]: 4                         

Where the query returns more than one row, the additional index results can be accessed by specifying the desired index, e.g. .index[n]

In [3]: a[a['c2'] >= 7].index[1]     In [4]: a[(a['c2'] > 1) & (a['c1'] < 8)].index[2]  
Out[3]: 4                            Out[4]: 3 

Let us see a more updated approach to this question:

Import AudioToolbox

func noteSelector(noteNumber: String) {

    if let soundURL = Bundle.main.url(forResource: noteNumber, withExtension: "wav") {
        var mySound: SystemSoundID = 0
        AudioServicesCreateSystemSoundID(soundURL as CFURL, &mySound)
        AudioServicesPlaySystemSound(mySound)
}

This example does not swap two int pointers. It swaps the value of the integers that pa and pb are pointing to. Here's an example of what's going on when you call this:

void Swap1 (int *pa, int *pb){
    int temp = *pa;
    *pa = *pb;
    *pb = temp;
}

int main()
{
    int a = 42;
    int b = 17;


    int *pa = &a;
    int *pb = &b;

    printf("--------Swap1---------\n");
    printf("a = %d\n b = %d\n", a, b);
    swap1(pa, pb);
    printf("a = %d\n = %d\n", a, a);
    printf("pb address =  %p\n", pa);
    printf("pa address =  %p\n", pb);
}

The output here is:

a = 42
b = 17
pa address =  0x7fffdf933228
pb address =  0x7fffdf93322c
--------Swap---------
pa = 17
pb = 42
a = 17
b = 42
pa address =  0x7fffdf933228
pb address =  0x7fffdf93322c

Note that the values swapped, but the pointer's addresses did not swap!

In order to swap addresses we need to do this:

void swap2 (int **pa, int **pb){
    int temp = *pa;
    *pa = *pb;
    *pb = temp;
}

and in main call the function like swap2(&pa, &pb);

Now the addresses are swapped, as well as the values for the pointers. a and b have the same values that the are initialized with The integers a and b did not swap because it swap2 swaps the addresses being being pointed to by the pointers!:

a = 42
b = 17
pa address =  0x7fffddaa9c98
pb address =  0x7fffddaa9c9c
--------Swap---------
pa = 17
pb = 42
a = 42
b = 17
pa address =  0x7fffddaa9c9c
pb address =  0x7fffddaa9c98

Since Strings in C are char pointers, and you want to swap Strings, you are really swapping a char pointer. As in the examples with an int, you need a double pointer to swap addresses.

The values of integers can be swapped even if the address isn't, but Strings are by definition a character pointer. You could swap one char with single pointers as the parameter, but a character pointer needs to be a double pointer in order to swap the strings.

Some options without REGEXMATCH, since you might want to be case insensitive and not want say blast or ablative to trigger a YES. Using comma as the delimiter, as in the OP, and for the moment ignoring the IF condition:

First very similar to @user1598086's answer:

=FIND("bla",A1)

Is case sensitive but returns #VALUE! rather than NO and a number rather than YES (both of which can however be changed to NO/YES respectively).

=SEARCH("bla",A1)  

Case insensitive, so treats Black and black equally. Returns as above.

The former (for the latter equivalent) to indicate whether bla present after the first three characters in A1:

=FIND("bla",A1,4)  

Returns a number for blazer, black but #VALUE! for blazer, blue.

To find Bla only when a complete word on its own (ie between spaces - not at the start or end of a 'sentence'):

=SEARCH(" Bla ",A1) 

Since the return in all cases above is either a number ("found", so YES preferred) or #VALUE! we can use ISERROR to test for #VALUE! within an IF formula, for instance taking the first example above:

 =if(iserror(FIND("bla",A1)),"NO","YES")  

Longer than the regexmatch but the components are easily adjustable.

This is a example for get the url image, escape the p tag from some item.

Try this:

$('#img').attr('src').split('<p>')[1].split('</p>')[0]

Taking @chrissr's answer and running with it, this code can be implemented into a nice category on NSUserDefaults to save and retrieve custom objects:

@interface NSUserDefaults (NSUserDefaultsExtensions)

- (void)saveCustomObject:(id<NSCoding>)object
                     key:(NSString *)key;
- (id<NSCoding>)loadCustomObjectWithKey:(NSString *)key;

@end


@implementation NSUserDefaults (NSUserDefaultsExtensions)


- (void)saveCustomObject:(id<NSCoding>)object
                     key:(NSString *)key {
    NSData *encodedObject = [NSKeyedArchiver archivedDataWithRootObject:object];
    [self setObject:encodedObject forKey:key];
    [self synchronize];

}

- (id<NSCoding>)loadCustomObjectWithKey:(NSString *)key {
    NSData *encodedObject = [self objectForKey:key];
    id<NSCoding> object = [NSKeyedUnarchiver unarchiveObjectWithData:encodedObject];
    return object;
}

@end

Usage:

[[NSUserDefaults standardUserDefaults] saveCustomObject:myObject key:@"myKey"];

Use a regular expression:

import re
def RepresentsInt(s):
    return re.match(r"[-+]?\d+$", s) is not None

If you must accept decimal fractions also:

def RepresentsInt(s):
    return re.match(r"[-+]?\d+(\.0*)?$", s) is not None

For improved performance if you're doing this often, compile the regular expression only once using re.compile().

(Git 2.22, Q2 2019, has introduced git submodule set-branch --branch aBranch -- <submodule_path>)

Note that if you have an existing submodule which isn't tracking a branch yet, then (if you have git 1.8.2+):

• Make sure the parent repo knows that its submodule now tracks a branch:

    cd /path/to/your/parent/repo
    git config -f .gitmodules submodule.<path>.branch <branch>
  

• Make sure your submodule is actually at the latest of that branch:

    cd path/to/your/submodule
    git checkout -b branch --track origin/branch
      # if the master branch already exist:
      git branch -u origin/master master
  

         (with 'origin' being the name of the upstream remote repo the submodule has been cloned from.
         A git remote -v inside that submodule will display it. Usually, it is 'origin')

• Don't forget to record the new state of your submodule in your parent repo:

    cd /path/to/your/parent/repo
    git add path/to/your/submodule
    git commit -m "Make submodule tracking a branch"
  

• Subsequent update for that submodule will have to use the --remote option:

    # update your submodule
    # --remote will also fetch and ensure that
    # the latest commit from the branch is used
    git submodule update --remote
  
    # to avoid fetching use
    git submodule update --remote --no-fetch 
  

Note that with Git 2.10+ (Q3 2016), you can use '.' as a branch name:

The name of the branch is recorded as submodule.<name>.branch in .gitmodules for update --remote.
A special value of . is used to indicate that the name of the branch in the submodule should be the same name as the current branch in the current repository.

But, as commented by LubosD

With git checkout, if the branch name to follow is ".", it will kill your uncommitted work!
Use git switch instead.

That means Git 2.23 (August 2019) or more.

See "Confused by git checkout"

If you want to update all your submodules following a branch:

    git submodule update --recursive --remote

Note that the result, for each updated submodule, will almost always be a detached HEAD, as Dan Cameron note in his answer.

(Clintm notes in the comments that, if you run git submodule update --remote and the resulting sha1 is the same as the branch the submodule is currently on, it won't do anything and leave the submodule still "on that branch" and not in detached head state.)

To ensure the branch is actually checked out (and that won't modify the SHA1 of the special entry representing the submodule for the parent repo), he suggests:

git submodule foreach -q --recursive 'branch="$(git config -f $toplevel/.gitmodules submodule.$name.branch)"; git switch $branch'

Each submodule will still reference the same SHA1, but if you do make new commits, you will be able to push them because they will be referenced by the branch you want the submodule to track.
After that push within a submodule, don't forget to go back to the parent repo, add, commit and push the new SHA1 for those modified submodules.

Note the use of $toplevel, recommended in the comments by Alexander Pogrebnyak.
$toplevel was introduced in git1.7.2 in May 2010: commit f030c96.

it contains the absolute path of the top level directory (where .gitmodules is).

dtmland adds in the comments:

The foreach script will fail to checkout submodules that are not following a branch.
However, this command gives you both:

 git submodule foreach -q --recursive 'branch="$(git config -f $toplevel/.gitmodules submodule.$name.branch)"; [ "$branch" = "" ] && git checkout master || git switch $branch' –

The same command but easier to read:

git submodule foreach -q --recursive \
    'branch="$(git config -f $toplevel/.gitmodules submodule.$name.branch)"; \
     [ "$branch" = "" ] && \
     git checkout master || git switch $branch' –
  

umläute refines dtmland's command with a simplified version in the comments:

git submodule foreach -q --recursive 'git switch $(git config -f $toplevel/.gitmodules submodule.$name.branch || echo master)'

multiple lines:

git submodule foreach -q --recursive \
  'git switch \
  $(git config -f $toplevel/.gitmodules submodule.$name.branch || echo master)'

Before Git 2.26 (Q1 2020), a fetch that is told to recursively fetch updates in submodules inevitably produces reams of output, and it becomes hard to spot error messages.

The command has been taught to enumerate submodules that had errors at the end of the operation.

fetch: emphasize failure during submodule fetch

^{Signed-off-by: Emily Shaffer}

In cases when a submodule fetch fails when there are many submodules, the error from the lone failing submodule fetch is buried under activity on the other submodules if more than one fetch fell back on fetch-by-oid.
Call out a failure late so the user is aware that something went wrong, and where.

Because fetch_finish() is only called synchronously by run_processes_parallel, mutexing is not required around submodules_with_errors.

Note that, with Git 2.28 (Q3 2020), Rewrite of parts of the scripted "git submodule" Porcelain command continues; this time it is "git submodule set-branch" subcommand's turn.

forget all the answers, this line of CSS worked for me in 2 seconds :

height:100vh;

1vh = 1% of browser screen height

source

For responsive layout scaling, you might want to use :

min-height: 100vh

[update november 2018] As mentionned in the comments, using the min-height might avoid having issues on reponsive designs

[update april 2018] As mentioned in the comments, back in 2011 when the question was asked, not all browsers supported the viewport units. The other answers were the solutions back then -- vmax is still not supported in IE, so this might not be the best solution for all yet.

By.cssSelector(".ban") or By.cssSelector(".hot") or By.cssSelector(".ban.hot") should all select it unless there is another element that has those classes.

In CSS, .name means find an element that has a class with name. .foo.bar.baz means to find an element that has all of those classes (in the same element).

However, each of those selectors will select only the first element that matches it on the page. If you need something more specific, please post the HTML of the other elements that have those classes.

Android does not have a specification to indicate the type of resource string (e.g. text/plain or text/html). There is a workaround, however, that will allow the developer to specify this within the XML file.

1. Define a custom attribute to specify that the android:text attribute is html.
2. Use a subclassed TextView.

Once you define these, you can express yourself with HTML in xml files without ever having to call setText(Html.fromHtml(...)) again. I'm rather surprised that this approach is not part of the API.

This solution works to the degree that the Android studio simulator will display the text as rendered HTML.

res/values/strings.xml (the string resource as HTML)

<resources>
<string name="app_name">TextViewEx</string>
<string name="string_with_html"><![CDATA[
       <em>Hello</em> <strong>World</strong>!
 ]]></string>
</resources>

layout.xml (only the relevant parts)

Declare the custom attribute namespace, and add the android_ex:isHtml attribute. Also use the subclass of TextView.

<RelativeLayout
...
xmlns:android_ex="http://schemas.android.com/apk/res-auto"
...>

<tv.twelvetone.samples.textviewex.TextViewEx
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:text="@string/string_with_html"
    android_ex:isHtml="true"
    />
 </RelativeLayout>

res/values/attrs.xml (define the custom attributes for the subclass)

 <resources>
<declare-styleable name="TextViewEx">
    <attr name="isHtml" format="boolean"/>
    <attr name="android:text" />
</declare-styleable>
</resources>

TextViewEx.java (the subclass of TextView)

 package tv.twelvetone.samples.textviewex;

 import android.content.Context;
 import android.content.res.TypedArray;
 import android.support.annotation.Nullable;
 import android.text.Html;
 import android.util.AttributeSet;
 import android.widget.TextView;

public TextViewEx(Context context, @Nullable AttributeSet attrs) {
    super(context, attrs);
    TypedArray a = context.obtainStyledAttributes(attrs, R.styleable.TextViewEx, 0, 0);
    try {
        boolean isHtml = a.getBoolean(R.styleable.TextViewEx_isHtml, false);
        if (isHtml) {
            String text = a.getString(R.styleable.TextViewEx_android_text);
            if (text != null) {
                setText(Html.fromHtml(text));
            }
        }
    } catch (Exception e) {
        e.printStackTrace();
    } finally {
        a.recycle();
    }
}
}

Use DateFormat.getDateInstance(int style, Locale locale) instead of creating your own patterns with SimpleDateFormat.

I had this problem with Blend for Visual Studio 2015. The Toolbox would just not appear anymore. This turns out to be because Blend is not Visual Studio!

(You can edit your code in Blend and build and run it... It certainly seems like Visual Studio, but it isn't. I'm not sure what the purpose of Blend is...)

You can tell you are in Blend if the task bar icon has big "B" in it. To switch from Blend to Visual Studio, go to View-> Edit in Visual Studio.... It will open up another application that looks just like Blend, except the Solution Explorer is on the right instead of the left, and now you have a toolbox...

Git offers a range of difftools pre-configured "out-of-the-box" (kdiff3, kompare, tkdiff, meld, xxdiff, emerge, vimdiff, gvimdiff, ecmerge, diffuse, opendiff, p4merge and araxis), and also allows you to specify your own. To use one of the pre-configured difftools (for example, "vimdiff"), you add the following lines to your ~/.gitconfig:

[diff]
    tool = vimdiff

Now, you will be able to run "git difftool" and use your tool of choice.

Specifying your own difftool, on the other hand, takes a little bit more work, see How do I view 'git diff' output with my preferred diff tool/ viewer?

From http://expressjs.com/api.html#cookieSession

To clear a cookie simply assign the session to null before responding:

req.session = null

You just need parentheses around your select:

SET @times = (SELECT COUNT(DidWin) FROM ...)

Or you can do it like this:

SELECT @times = COUNT(DidWin) FROM ...

Based on my experience on Ubuntu 18.04:

1. Check Jupyter installation

first of all make sure that you have installed and/or upgraded Jupyter-notebook (also for virtual-environment):

pip install --upgrade jupyter 

2. Change the Access Permissions (Use with Caution!)

then try to change the access permission for you

sudo chmod -R 777 ~/.local

where 777 is a three-digit representation of the access permission. In sense that each of the digits representing short format of the binary one (e.g. 7 for 111). So, 777 means that we set permission access to read, write and execute to 1 for all users (Owner, Group or Other)

Example.1

777 : 111 111 111

or

777 : rwx-rwx-rwx

Example.2

755 : 111 101 101

• Owner: rwx=4+2+1=7
• Group: r-x=4+0+1=5
• Other: r-x=4+0+1=5

(More about chmod : File Permissions and attributes)

3. Run jupyter

afterwards run your jupyter notebook:

jupyter-notebook

Note: (These steps also solve your Visual-Studio code (VS-Code) problems regarding permissions while using ipython and jupyter for python-interactive-console.)

I know it's not your specific problem, but I faced the same symptoms when I configured a static IP address in the network adapter settings and forgot to enter a "Default Gateway".

Leaving the field blank, the network icon shows an Internet connection, and I could ping internal servers but not external ones, so I assumed it was a DNS problem. NSLookup still worked, but of course, ping failed to find the server (again, seemed like a DNS issue.) Anyway, one more thing to check. =P

I used the sdk.

eg:

using SevenZip.Compression.LZMA;
private static void CompressFileLZMA(string inFile, string outFile)
{
   SevenZip.Compression.LZMA.Encoder coder = new SevenZip.Compression.LZMA.Encoder();

   using (FileStream input = new FileStream(inFile, FileMode.Open))
   {
      using (FileStream output = new FileStream(outFile, FileMode.Create))
      {
          coder.Code(input, output, -1, -1, null);
          output.Flush();
      }
   }
}

Further to @T.J. Crowder 's answer, I've added a recursive outer loop that allows one to iterate through all the scripts in an array and then execute a function once all the scripts are loaded:

loadList([array of scripts], 0, function(){// do your post-scriptload stuff})

function loadList(list, i, callback)
{
    {
        loadScript(list[i], function()
        {
            if(i < list.length-1)
            {
                loadList(list, i+1, callback);  
            }
            else
            {
                callback();
            }
        })
    }
}

Of course you can make a wrapper to get rid of the '0' if you like:

function prettyLoadList(list, callback)
{
    loadList(list, 0, callback);
}

Nice work @T.J. Crowder - I was cringing at the 'just add a couple seconds delay before running the callback' I saw in other threads.

Well i had the same problem what when i added the following code within the tag my problem fixed :

    <head>
       <meta name="viewport" content="width=device-width , initial-scale=1" />
    </head>

I hope this can help you guys!

Just drag and drop the DLL file into folder C:\Windows\assembly using Windows Explorer.

Caveat:

In earlier versions of the .NET Framework, the Shfusion.dll Windows shell extension let you install assemblies by dragging them to File Explorer. Beginning with .NET Framework 4, Shfusion.dll is obsolete.

I had same issue and now I finally resolved it. I am not using docker-compose file. I just added this line in my Docker file and it worked.

I already knew about the color escapes, I used them in my bash prompt a while ago. Thanks anyway.
What I wanted was to integrate it with the logging module, which I eventually did after a couple of tries and errors.
Here is what I end up with:

BLACK, RED, GREEN, YELLOW, BLUE, MAGENTA, CYAN, WHITE = range(8)

#The background is set with 40 plus the number of the color, and the foreground with 30

#These are the sequences need to get colored ouput
RESET_SEQ = "\033[0m"
COLOR_SEQ = "\033[1;%dm"
BOLD_SEQ = "\033[1m"

def formatter_message(message, use_color = True):
    if use_color:
        message = message.replace("$RESET", RESET_SEQ).replace("$BOLD", BOLD_SEQ)
    else:
        message = message.replace("$RESET", "").replace("$BOLD", "")
    return message

COLORS = {
    'WARNING': YELLOW,
    'INFO': WHITE,
    'DEBUG': BLUE,
    'CRITICAL': YELLOW,
    'ERROR': RED
}

class ColoredFormatter(logging.Formatter):
    def __init__(self, msg, use_color = True):
        logging.Formatter.__init__(self, msg)
        self.use_color = use_color

    def format(self, record):
        levelname = record.levelname
        if self.use_color and levelname in COLORS:
            levelname_color = COLOR_SEQ % (30 + COLORS[levelname]) + levelname + RESET_SEQ
            record.levelname = levelname_color
        return logging.Formatter.format(self, record)

And to use it, create your own Logger:

# Custom logger class with multiple destinations
class ColoredLogger(logging.Logger):
    FORMAT = "[$BOLD%(name)-20s$RESET][%(levelname)-18s]  %(message)s ($BOLD%(filename)s$RESET:%(lineno)d)"
    COLOR_FORMAT = formatter_message(FORMAT, True)
    def __init__(self, name):
        logging.Logger.__init__(self, name, logging.DEBUG)                

        color_formatter = ColoredFormatter(self.COLOR_FORMAT)

        console = logging.StreamHandler()
        console.setFormatter(color_formatter)

        self.addHandler(console)
        return


logging.setLoggerClass(ColoredLogger)

Just in case anyone else needs it.

Be careful if you're using more than one logger or handler: ColoredFormatter is changing the record object, which is passed further to other handlers or propagated to other loggers. If you have configured file loggers etc. you probably don't want to have the colors in the log files. To avoid that, it's probably best to simply create a copy of record with copy.copy() before manipulating the levelname attribute, or to reset the levelname to the previous value, before returning the formatted string (credit to Michael in the comments).

The following steps are necessary to create .exe i.e. executable files which are as 1) Open visual studio framework 2) Then, create a new project or application 3) Build or execute your application by pressing F5

Use time.mktime() to convert the time tuple (in localtime) into seconds since the Epoch, then use datetime.fromtimestamp() to get the datetime object.

from datetime import datetime
from time import mktime

dt = datetime.fromtimestamp(mktime(struct))

This was helpful to use in COGNOS because creating a SQL "Not in" statement in Cognos was allowed, but it took too long to run. I had manually coded table A to join to table B in in Cognos as A.key "not in" B.key, but the query was taking too long/not returning results after 5 minutes.

For anyone else that is looking for a "NOT IN" solution in Cognos, here is what I did. Create a Query that joins table A and B with a LEFT JOIN in Cognos by selecting link type: table A.Key has "0 to N" values in table B, then added a Filter (these correspond to Where Clauses) for: table B.Key is NULL.

Ran fast and like a charm.

      while ((pos=token.rfind(',')) != std::string::npos) {
        token.erase(pos, 1);
      }
      std::cout << token << '\n';

check pyplot docs. For completeness,

import numpy as np
import matplotlib.pyplot as plt

#evenly sampled time at 200ms intervals
t = np.arange(0., 5., 0.2)

# red dashes, blue squares and green triangles
plt.plot(t, t, 'r--', t, t**2, 'bs', t, t**3, 'g^')
plt.show()

From the Intel Instructions

"The SDK Manager will download the installer to the "extras" directory, under the main SDK directory. Even though the SDK manager says "Installed" it actually means that the Intel HAXM executable was downloaded. You will still need to run the installer from the "extras" directory to finish installation.

Extract the installer inside the "extras" directory and follow the installation instructions for your platform."

You can scale up the fonts in your call to sns.set().

import numpy as np
import matplotlib.pyplot as plt
import seaborn as sns
x = np.random.normal(size=37)
y = np.random.lognormal(size=37)

# defaults
sns.set()
fig, ax = plt.subplots()
ax.plot(x, y, marker='s', linestyle='none', label='small')
ax.legend(loc='upper left', bbox_to_anchor=(0, 1.1))

sns.set(font_scale=5)  # crazy big
fig, ax = plt.subplots()
ax.plot(x, y, marker='s', linestyle='none', label='big')
ax.legend(loc='upper left', bbox_to_anchor=(0, 1.3))

You Can Simply follow this step Create a jar file using

 jar -cfm jarfile-name manifest-filename Class-file name

While running the jar file simple run like this

 java -cp jarfile-name main-classname

curl will encode the data for you, just drop your raw field data into the fields array and tell it to "go".

Try the below steps:

1. Close Eclipse if running
2. Go to the Android SDK platform-tools directory in the command prompt
3. Type adb kill-server (Eclipse should be closed before issuing these commands)
4. Then type adb start-server
5. No error message is thrown while starting the ADB server, then ADB is started successfully.
6. Now you can start Eclipse again.

It worked for me this way.

Restart your phone as well!

What system are you running on? Do you have access to some sort of debugger (gdb, visual studio's debugger, etc.)?

That would give us valuable information, like the line of code where the program crashes... Also, the amount of memory may be prohibitive.

Additionally, may I recommend that you replace the numeric limits by named definitions?

As such:

#define DIM1_SZ 1000
#define DIM2_SZ 1000000

Use those whenever you wish to refer to the array dimension limits. It will help avoid typing errors.

is it fine to check for a Date related function is available for the object to find whether it is a Date object or not ?

like

var l = new Date();
var isDate = (l.getDate !== undefined) ? true; false;

(document.body.outerHTML).constructor will return String. (take off .constructor and that's your string)

That aughta do it :)

The problem is related to AppCompat library. With it, you have

xmlns:appname="http://schemas.android.com/apk/res-auto"

and possibly:

appname:showAsAction="never"

in menu.xml file.

Without the lib, you can only have:

android:showAsAction="never"

and my app works with menu both on Android 4.3 and 2.3.3.

My solution is to use ggplot2. It takes care of these types of things automatically. The biggest thing is to arrange the data appropriately.

y1 <- c(100, 200, 300, 400, 500)
y2 <- c(1, 2, 3, 4, 5)
x <- c(1, 2, 3, 4, 5)
df <- data.frame(x=rep(x,2), y=c(y1, y2), class=c(rep("y1", 5), rep("y2", 5)))

Then use ggplot2 to plot it

library(ggplot2)
ggplot(df, aes(x=x, y=y, color=class)) + geom_point()

This is saying plot the data in df, and separate the points by class.

The plot generated is

I wanted to do the same, and I had first problems with the split function, then problems with installing pandas 0.15.2, so I went back to my old version, and wrote a little function that works very well. I hope this can help!

# input - df: a Dataframe, chunkSize: the chunk size
# output - a list of DataFrame
# purpose - splits the DataFrame into smaller chunks
def split_dataframe(df, chunk_size = 10000): 
    chunks = list()
    num_chunks = len(df) // chunk_size + 1
    for i in range(num_chunks):
        chunks.append(df[i*chunk_size:(i+1)*chunk_size])
    return chunks

Collections by themselves do not have a predefined order, therefore you must convert them to a java.util.List. Then you can use one form of java.util.Collections.sort

Collection< T > collection = ...;

List< T > list = new ArrayList< T >( collection );

Collections.sort( list );
 // or
Collections.sort( list, new Comparator< T >( ){...} );

// list now is sorted

Maybe this helps other people who come across the same issue.

My setup: old Gradle project (version Gradle 2.12) made by someone else, imported using the Gradle Import Wizard into STS (Eclipse Oxygen.2 (4.7.2)).

Code completion did not work either (and I still have hollow Js at the Java files), but at least I got the code completion to work by doing:

• right click on the project folder > Properties > Gradle > Configure Workspace Settings > Java > Editor > Content Assist > Advanced
• check "Java Proposals in upper window.
• 2x Apply & Close

ecatmur's solution will work fine. This will be better performance on large datasets, though:

data.groupby(data['date'].map(lambda x: x.year))

You just use this and it will be helpful for you

$("#btnForm").click(function (){

$.fancybox({
    'padding':  0,
    'width':    1087,
    'height':   610,
    'type':     'iframe',
    content:   $('#divForm').show();
        });

});

To set the use of scientific notation in your entire R session, you can use the scipen option. From the documentation (?options):

‘scipen’: integer.  A penalty to be applied when deciding to print
          numeric values in fixed or exponential notation.  Positive
          values bias towards fixed and negative towards scientific
          notation: fixed notation will be preferred unless it is more
          than ‘scipen’ digits wider.

So in essence this value determines how likely it is that scientific notation will be triggered. So to prevent scientific notation, simply use a large positive value like 999:

options(scipen=999)

It might seem silly , but if u wanna try utility function

System.out.println(Integer.parseInt((Integer.toString(i,2))));

there must be some utility method to do it directly, I cant remember.

If you really need to override css that has !important rules in it, for instance, in a case I ran into recently, overriding a wordpress theme required !important scss rules to break the theme, but since I was transpiling my code with webpack and (I assume this is why --)my css came along in the chain after the transpiled javascript, you can add a separate class rule in your stylesheet that overrides the first !important rule in the cascade, and toggle the heavier-weighted class rather than adjusting css dynamically. Just a thought.

By using '' you are making it to string. Use without inverted commas it will work fine.

JavaScript is fired on client side and JSP is on server-side. So I can say that it is impossible.

Using node I have a collection of stuff @stuff and access it like this:

@AlexeiLevenkov pointed me at another "easiest way" namely the extension method. It takes just a little coding, then provides the absolute easiest way to read/write, plus it offers the flexibility to create variations according to your personal needs. Here is a complete example:

This defines the extension method on the string type. Note that the only thing that really matters is the function argument with extra keyword this, that makes it refer to the object that the method is attached to. The class name does not matter; the class and method must be declared static.

using System.IO;//File, Directory, Path

namespace Lib
{
    /// <summary>
    /// Handy string methods
    /// </summary>
    public static class Strings
    {
        /// <summary>
        /// Extension method to write the string Str to a file
        /// </summary>
        /// <param name="Str"></param>
        /// <param name="Filename"></param>
        public static void WriteToFile(this string Str, string Filename)
        {
            File.WriteAllText(Filename, Str);
            return;
        }

        // of course you could add other useful string methods...
    }//end class
}//end ns

This is how to use the string extension method, note that it refers automagically to the class Strings:

using Lib;//(extension) method(s) for string
namespace ConsoleApp_Sandbox
{
    class Program
    {
        static void Main(string[] args)
        {
            "Hello World!".WriteToFile(@"c:\temp\helloworld.txt");
            return;
        }

    }//end class
}//end ns

I would never have found this myself, but it works great, so I wanted to share this. Have fun!

To answer the questions in terms of how you asked it.

This is actually REALLY easy (in Internet Explorer, at least), i did it in like 17.5 seconds.

If you use the custom script that cxfx provided: (place it in your apsx file)

<script language="VBScript">
Sub myAlert(title, content)
MsgBox content, 0, title 
End Sub 
</script>

You can then call it just like you called the regular alert. Just modify your code to the following.

Response.Write("<script language=JavaScript> myAlert('Message Header Here','Hi select a valid date'); </script>");

Hope that helps you, or someone else!

window.history.back() does not support reload or refresh of the page. But you can use following if you are okay with an extra refresh

window.history.back()
window.location.reload()

However a real complete solution would be as follows: I wrote a service to keep track of previous page and then navigate to that page with reload:true

Here is how i did it.

'use strict';

angular.module('tryme5App')
    .factory('RouterTracker', function RouterTracker($rootScope) {
          var routeHistory = [];
          var service = {
            getRouteHistory: getRouteHistory
          };

          $rootScope.$on('$stateChangeSuccess', function (ev, to, toParams, from, fromParams) {
              routeHistory = [];
              routeHistory.push({route: from, routeParams: fromParams});
          });

          function getRouteHistory() {
            return routeHistory;
          }

          return service;       
    });

Make sure you have included this js file from you index.html

<script src="scripts/components/util/route.service.js"></script>

Now from you stateprovider or controller you can access this service and navigate

var routeHistory = RouterTracker.getRouteHistory();    
console.log(routeHistory[0].route.name)
$state.go(routeHistory[0].route.name, null, { reload: true });

or alternatively even perform checks and conditional routing

var routeHistory = RouterTracker.getRouteHistory();    
console.log(routeHistory[0].route.name)
if(routeHistory[0].route.name == 'seat') {
      $state.go('seat', null, { reload: true });
} else {
      window.history.back()
}

Make sure you have added RouterTracker as an argument in your function in my case it was :

.state('seat.new', {
                parent: 'seat',
                url: '/new',
                data: {
                    authorities: ['ROLE_USER'],
                },
                onEnter: ['$stateParams', '$state', '$uibModal', 'RouterTracker', function($stateParams, $state, $uibModal, RouterTracker) {
  $uibModal.open({
      //....Open dialog.....
 }).result.then(function(result) {
            var routeHistory = RouterTracker.getRouteHistory();    
            console.log(routeHistory[0].route.name)
            $state.go(routeHistory[0].route.name, null, { reload: true });
 }, function() {
                    $state.go('^');
 })

Save the archiveName image to a tar file. I will use the /media/sf_docker_vm/ to save the image.

stratos@Dev-PC:~$ docker save imageID > /media/sf_docker_vm/archiveName.tar

Copy the archiveName.tar file to your new Docker instance using whatever method works in your environment, for example FTP, SCP, etc.

Run the docker load command on your new Docker instance and specify the location of the image tar file.

stratos@Dev-PC:~$ docker load < /media/sf_docker_vm/archiveName.tar

Finally, run the docker images command to check that the image is now available.

stratos@Dev-PC:~$ docker images

Please find this detailed post.

You can use the following two functions so as to avoid writing a wrapper for each new function:

import itertools
from multiprocessing import Pool

def universal_worker(input_pair):
    function, args = input_pair
    return function(*args)

def pool_args(function, *args):
    return zip(itertools.repeat(function), zip(*args))

Use the function function with the lists of arguments arg_0, arg_1 and arg_2 as follows:

pool = Pool(n_core)
list_model = pool.map(universal_worker, pool_args(function, arg_0, arg_1, arg_2)
pool.close()
pool.join()

Great Start to learning login forms. You are right, fieldset may not be the best tag.

However, I highly suggest you code it in HTML5 by using its robust form features.

HTML5 is actually easier to learn than older HTML for creating forms.

For example, read the following.

<section class="loginform cf">  
    <form name="login" action="index_submit" method="get" accept-charset="utf-8">  
        <ul>  
            <li><label for="usermail">Email</label>  
            <input type="email" name="usermail" placeholder="[email protected]" required></li>  
            <li><label for="password">Password</label>  
            <input type="password" name="password" placeholder="password" required></li>  
            <li>  
            <input type="submit" value="Login"></li>  
        </ul>  
    </form>  
</section>

Wasn't that easy for you to understand?

Try this http://www.hongkiat.com/blog/html5-loginpage/ and let me know if you have any questions.

Another way of creating and initializing an array of objects. This is similar to the example which @Amol has posted above, except this one uses constructors. A dash of polymorphism sprinkled in, I couldn't resist.

IUser[] userArray = new IUser[]
{
    new DummyUser("[email protected]", "Gibberish"),
    new SmartyUser("[email protected]", "Italian", "Engineer")
};

Classes for context:

interface IUser
{
    string EMail { get; }       // immutable, so get only an no set
    string Language { get; }
}

public class DummyUser : IUser
{
    public DummyUser(string email, string language)
    {
        m_email = email;
        m_language = language;
    }

    private string m_email;
    public string EMail
    {
        get { return m_email; }
    }

    private string m_language;
    public string Language
    {
        get { return m_language; }
    }
}

public class SmartyUser : IUser
{
    public SmartyUser(string email, string language, string occupation)
    {
        m_email = email;
        m_language = language;
        m_occupation = occupation;
    }

    private string m_email;
    public string EMail
    {
        get { return m_email; }
    }

    private string m_language;
    public string Language
    {
        get { return m_language; }
    }

    private string m_occupation;
}

controller_name holds the name of the controller used to serve the current view.

Here is the direct solution:

// POST api/<controller>
[HttpPost, Route("postproducts/{product1}/{product2}")]
public void PostProducts([FromUri]Product product, Product product2)
{
    Product productOne = product; 
    Product productTwo = product2; 
}

$scope.url = 'http://localhost:53263/api/Products/' +
                 $scope.product + '/' + $scope.product2
$http.post($scope.url)
    .success(function(response) {
        alert("success") 
    })
    .error(function() { alert("fail") });
};

If you are sane you do this:

var $scope.products.product1 = product1;
var $scope.products.product2 = product2;

And then send products in the body (like a balla).

Others have already properly compared delete with splice.

Another interesting comparison is delete versus undefined: a deleted array item uses less memory than one that is just set to undefined;

For example, this code will not finish:

let y = 1;
let ary = [];
console.log("Fatal Error Coming Soon");
while (y < 4294967295)
{
    ary.push(y);
    ary[y] = undefined;
    y += 1;
}
console(ary.length);

It produces this error:

FATAL ERROR: CALL_AND_RETRY_LAST Allocation failed - JavaScript heap out of memory.

So, as you can see undefined actually takes up heap memory.

However, if you also delete the ary-item (instead of just setting it to undefined), the code will slowly finish:

let x = 1;
let ary = [];
console.log("This will take a while, but it will eventually finish successfully.");
while (x < 4294967295)
{
    ary.push(x);
    ary[x] = undefined;
    delete ary[x];
    x += 1;
}
console.log(`Success, array-length: ${ary.length}.`);

These are extreme examples, but they make a point about delete that I haven't seen anyone mention anywhere.

This below command worked for me

Python version - 2.7

package - python-jenkins

command - $ pip install 'python-jenkins>=1.1.1'

The foreach construct is unfortunately not intrinsic to collections but instead external to them. The result is two-fold:

• it can not be chained
• it requires two lines in idiomatic python.

Python does not support a true foreach on collections directly. An example would be

myList.foreach( a => print(a)).map( lambda x:  x*2)

But python does not support it. Partial fixes to this and other missing functionals features in python are provided by various third party libraries including one that I helped author: see https://pypi.org/project/infixpy/

You can explicitly specify the return type of a lambda by using -> Type after the arguments list:

[]() -> Type { }

However, if a lambda has one statement and that statement is a return statement (and it returns an expression), the compiler can deduce the return type from the type of that one returned expression. You have multiple statements in your lambda, so it doesn't deduce the type.

The li tag has a property called list-style-position. This makes your bullets inside or outside the list. On default, it’s set to inside. That makes your text wrap around it. If you set it to outside, the text of your li tags will be aligned.

The downside of that is that your bullets won't be aligned with the text outside the ul. If you want to align it with the other text you can use a margin.

ul li {
    /*
     * We want the bullets outside of the list,
     * so the text is aligned. Now the actual bullet
     * is outside of the list’s container
     */
    list-style-position: outside;

    /*
     * Because the bullet is outside of the list’s
     * container, indent the list entirely
     */
    margin-left: 1em;
}

Edit 15th of March, 2014 Seeing people are still coming in from Google, I felt like the original answer could use some improvement

• Changed the code block to provide just the solution
• Changed the indentation unit to em’s
• Each property is applied to the ul element
• Good comments :)

From version 4.x, only Android SDK 24+ is supported by default, and androidx is required.

Add the following to your build.gradle file:

repositories {
    jcenter()
}

dependencies {
    implementation 'com.journeyapps:zxing-android-embedded:4.1.0'
    implementation 'androidx.appcompat:appcompat:1.0.2'
}

android {
    buildToolsVersion '28.0.3' // Older versions may give compile errors
}

Older SDK versions

For Android SDK versions < 24, you can downgrade zxing:core to 3.3.0 or earlier for Android 14+ support:

repositories {
    jcenter()
}

dependencies {
    implementation('com.journeyapps:zxing-android-embedded:4.1.0') { transitive = false }
    implementation 'androidx.appcompat:appcompat:1.0.2'
    implementation 'com.google.zxing:core:3.3.0'
}

android {
    buildToolsVersion '28.0.3'
}

You'll also need this in your Android manifest:

<uses-sdk tools:overrideLibrary="com.google.zxing.client.android" />

Source : https://github.com/journeyapps/zxing-android-embedded

The simple version is 0x is a prefix denoting a hexadecimal number, source.

So the value you're computing is after the prefix, in this case 10.

But that is not the number 10. The most significant bit 1 denotes the hex value while 0 denotes the units.

So the simple math you would do is

0x10

1 * 16 + 0 = 16

Note - you use 16 because hex is base 16.

Another example:

0xF7

15 * 16 + 7 = 247

You can get a list of values by searching for a hex table. For instance in this chart notice F corresponds with 15.

I would suggest creating a wrapper around XmlWriter object, so it would count amount of calls to WriteStartElement/WriteEndElement, and if you limit amount of tags to some number (f.e. 100), you would be able to throw a different exception, for example - InvalidOperation.

That should solve the problem in the majority of the cases

    private readonly XmlWriter _innerWriter;

}

Nothing compares to extjs in terms of community size and presence on StackOverflow. Despite previous controversy, Ext JS now has a GPLv3 open source license. Its learning curve is long, but it can be quite rewarding once learned. Ext JS lacks a Material Design theme, and the team has repeatedly refused to release the source code on GitHub. For mobile, one must use the separate Sencha Touch library.

Have in mind also that,

large JavaScript libraries, such as YUI, have been receiving less attention from the community. Many developers today look at large JavaScript libraries as walled gardens they don’t want to be locked into.

-- Announcement of YUI development being ceased

That said, below are a number of Ext JS alternatives currently available.

Leading client widget libraries

1. Blueprint is a React-based UI toolkit developed by big data analytics company Palantir in TypeScript, and "optimized for building complex data-dense interfaces for desktop applications". Actively developed on GitHub as of May 2019, with comprehensive documentation. Components range from simple (chips, toast, icons) to complex (tree, data table, tag input with autocomplete, date range picker. No accordion or resizer.

   Blueprint targets modern browsers (Chrome, Firefox, Safari, IE 11, and Microsoft Edge) and is licensed under a modified Apache license.

   Sandbox / demo • GitHub • Docs

2. Webix - an advanced, easy to learn, mobile-friendly, responsive and rich free&open source JavaScript UI components library. Webix spun off from DHTMLX Touch (a project with 8 years of development behind it - see below) and went on to become a standalone UI components framework. The GPL3 edition allows commercial use and lets non-GPL applications using Webix keep their license, e.g. MIT, via a license exemption for FLOSS. Webix has 55 UI widgets, including trees, grids, treegrids and charts. Funding comes from a commercial edition with some advanced widgets (Pivot, Scheduler, Kanban, org chart etc.). Webix has an extensive list of free and commercial widgets, and integrates with most popular frameworks (React, Vue, Meteor, etc) and UI components.

   

   Skins look modern, and include a Material Design theme. The Touch theme also looks quite Material Design-ish. See also the Skin Builder.

   Minimal GitHub presence, but includes the library code, and the documentation (which still needs major improvements). Webix suffers from a having a small team and a lack of marketing. However, they have been responsive to user feedback, both on GitHub and on their forum.

   The library was lean (128Kb gzip+minified for all 55 widgets as of ~2015), faster than ExtJS, dojo and others, and the design is pleasant-looking. The current version of Webix (v6, as of Nov 2018) got heavier (400 - 676kB minified but NOT gzipped).

   The demos on Webix.com look and function great. The developer, XB Software, uses Webix in solutions they build for paying customers, so there's likely a good, funded future ahead of it.

   Webix aims for backwards compatibility down to IE8, and as a result carries some technical debt.

3. react-md - MIT-licensed Material Design UI components library for React. Responsive, accessible. Implements components from simple (buttons, cards) to complex (sortable tables, autocomplete, tags input, calendars). One lead author, ~1900 GitHub stars.

4. kendo - jQuery-based UI toolkit with 40+ basic open-source widgets, plus commercial professional widgets (grids, trees, charts etc.). Responsive&mobile support. Works with Bootstrap and AngularJS. Modern, with Material Design themes. The documentation is available on GitHub, which has enabled numerous contributions from users (4500+ commits, 500+ PRs as of Jan 2015).

   

   Well-supported commercially, claiming millions of developers, and part of a large family of developer tools. Telerik has received many accolades, is a multi-national company (Bulgaria, US), was acquired by Progress Software, and is a thought leader.

   A Kendo UI Professional developer license costs $700 and posting access to most forums is conditioned upon having a license or being in the trial period.

   [Wikipedia] • GitHub/Telerik • Demos • Playground • Tools

5. OpenUI5 - jQuery-based UI framework with 180 widgets, Apache 2.0-licensed and fully-open sourced and funded by German software giant SAP SE.

   

   The community is much larger than that of Webix, SAP is hiring developers to grow OpenUI5, and they presented OpenUI5 at OSCON 2014.

   The desktop themes are rather lackluster, but the Fiori design for web and mobile looks clean and neat.

   Wikipedia • GitHub • Mobile-first controls demos • Desktop controls demos • SO

6. DHTMLX - JavaScript library for building rich Web and Mobile apps. Looks most like ExtJS - check the demos. Has been developed since 2005 but still looks modern. All components except TreeGrid are available under GPLv2 but advanced features for many components are only available in the commercial PRO edition - see for example the tree. Claims to be used by many Fortune 500 companies.

   

   Minimal presence on GitHub (the main library code is missing) and StackOverflow but active forum. The documentation is not available on GitHub, which makes it difficult to improve by the community.

7. Polymer, a Web Components polyfill, plus Polymer Paper, Google's implementation of the Material design. Aimed at web and mobile apps. Doesn't have advanced widgets like trees or even grids but the controls it provides are mobile-first and responsive. Used by many big players, e.g. IBM or USA Today.

   

8. Ant Design claims it is "a design language for background applications", influenced by "nature" and helping designers "create low-entropy atmosphere for developer team". That's probably a poor translation from Chinese for "UI components for enterprise web applications". It's a React UI library written in TypeScript, with many components, from simple (buttons, cards) to advanced (autocomplete, calendar, tag input, table).

   The project was born in China, is popular with Chinese companies, and parts of the documentation are available only in Chinese. Quite popular on GitHub, yet it makes the mistake of splitting the community into Chinese and English chat rooms. The design looks Material-ish, but fonts are small and the information looks lost in a see of whitespace.

9. PrimeUI - collection of 45+ rich widgets based on jQuery UI. Apache 2.0 license. Small GitHub community. 35 premium themes available.

10. qooxdoo - "a universal JavaScript framework with a coherent set of individual components", developed and funded by German hosting provider 1&1 (see the contributors, one of the world's largest hosting companies. GPL/EPL (a business-friendly license).

    Mobile themes look modern but desktop themes look old (gradients).

11. jQuery UI - easy to pick up; looks a bit dated; lacks advanced widgets. Of course, you can combine it with independent widgets for particular needs, e.g. trees or other UI components, but the same can be said for any other framework.

12. angular + Angular UI. While Angular is backed by Google, it's being radically revamped in the upcoming 2.0 version, and "users will need to get to grips with a new kind of architecture. It's also been confirmed that there will be no migration path from Angular 1.X to 2.0". Moreover, the consensus seems to be that Angular 2 won't really be ready for use until a year or two from now. Angular UI has relatively few widgets (no trees, for example).

13. DojoToolkit and their powerful Dijit set of widgets. Completely open-sourced and actively developed on GitHub, but development is now (Nov 2018) focused on the new dojo.io framework, which has very few basic widgets. BSD/AFL license. Development started in 2004 and the Dojo Foundation is being sponsored by IBM, Google, and others - see Wikipedia. 7500 questions here on SO.

    

    Themes look desktop-oriented and dated - see the theme tester in dijit. The official theme previewer is broken and only shows "Claro". A Bootstrap theme exists, which looks a lot like Bootstrap, but doesn't use Bootstrap classes. In Jan 2015, I started a thread on building a Material Design theme for Dojo, which got quite popular within the first hours. However, there are questions regarding building that theme for the current Dojo 1.10 vs. the next Dojo 2.0. The response to that thread shows an active and wide community, covering many time zones.

    Unfortunately, Dojo has fallen out of popularity and fewer companies appear to use it, despite having (had?) a strong foothold in the enterprise world. In 2009-2012, its learning curve was steep and the documentation needed improvements; while the documentation has substantially improved, it's unclear how easy it is to pick up Dojo nowadays.

    With a Material Design theme, Dojo (2.0?) might be the killer UI components framework.

14. Enyo - front-end library aimed at mobile and TV apps (e.g. large touch-friendly controls). Developed by LG Electronix and Apache-licensed on GitHub.

15. The radical Cappuccino - Objective-J (a superset of JavaScript) instead of HTML+CSS+DOM

16. Mochaui, MooTools UI Library User Interface Library. <300 GitHub stars.

17. CrossUI - cross-browser JS framework to develop and package the exactly same code and UI into Web Apps, Native Desktop Apps (Windows, OS X, Linux) and Mobile Apps (iOS, Android, Windows Phone, BlackBerry). Open sourced LGPL3. Featured RAD tool (form builder etc.). The UI looks desktop-, not web-oriented. Actively developed, small community. No presence on GitHub.

18. ZinoUI - simple widgets. The DataTable, for instance, doesn't even support sorting.

19. Wijmo - good-looking commercial widgets, with old (jQuery UI) widgets open-sourced on GitHub (their development stopped in 2013). Developed by ComponentOne, a division of GrapeCity. See Wijmo Complete vs. Open.

20. CxJS - commercial JS framework based on React, Babel and webpack offering form elements, form validation, advanced grid control, navigational elements, tooltips, overlays, charts, routing, layout support, themes, culture dependent formatting and more.

Widgets - Demo Apps - Examples - GitHub

Full-stack frameworks

1. SproutCore - developed by Apple for web applications with native performance, handling large data sets on the client. Powers iCloud.com. Not intended for widgets.

2. Wakanda: aimed at business/enterprise web apps - see What is Wakanda?. Architecture:

   • Wakanda Server (server-side JavaScript (custom engine) + open-source NoSQL database)
   • desktop IDE and WYSIWYG editor for tables, forms, reports

   • Wakanda Application Framework (datasource layer + browser-based interface widgets) that helps with browser and device compatibility across desktop and mobile

     Wakanda is highly integrated, includes a ton of features out of the box, but has a very small GitHub community and SO presence.

3. Servoy - "a cross platform frontend development and deployment environment for SQL databases". Boasts a "full WYSIWIG (What You See Is What You Get) UI designer for HTML5 with built-in data-binding to back-end services", responsive design, support for HTML6 Web Components, Websockets and mobile platforms. Written in Java and generates JavaScript code using various JavaBeans.

4. SmartClient/SmartGWT - mobile and cross-browser HTML5 UI components combined with a Java server. Aimed at building powerful business apps - see demos.

5. Vaadin - full-stack Java/GWT + JavaScript/HTML3 web app framework

6. Backbase - portal software

7. Shiny - front-end library on top R, with visualization, layout and control widgets

8. ZKOSS: Java+jQuery+Bootstrap framework for building enterprise web and mobile apps.

CSS libraries + minimal widgets

These libraries don't implement complex widgets such as tables with sorting/filtering, autocompletes, or trees.

1. Bootstrap

2. Foundation for Apps - responsive front-end framework on top of AngularJS; more of a grid/layout/navigation library

3. UI Kit - similar to Bootstrap, with fewer widgets, but with official off-canvas.

Libraries using HTML Canvas

Using the canvas elements allows for complete control over the UI, and great cross-browser compatibility, but comes at the cost of missing native browser functionality, e.g. page search via Ctrl/Cmd+F.

The standard MIME type for ZIP files is application/zip. The types for the files inside the ZIP does not matter for the MIME type.

As always, it ultimately depends on your server setup.

There is a wonderful print_r implementation for JavaScript in php.js library.

Note, you should also add echo support in the code.

In httpd.conf instead:

Listen *:443

you need write Listen 127.0.0.1:443 It works for me.

if (isset($_POST['Register']))
    {
        $ErrorArrays = array (); //Empty array for input errors 

        $Input_Username = $_POST['Username'];
        $Input_Password = $_POST['Password'];
        $Input_Confirm = $_POST['ConfirmPass'];
        $Input_Email = $_POST['Email'];

        if (empty($Input_Username))
        {
            $ErrorArrays[] = "Username Is Empty";
        }
        if (empty($Input_Password))
        {
            $ErrorArrays[] = "Password Is Empty";
        }
        if ($Input_Password !== $Input_Confirm)
        {
            $ErrorArrays[] = "Passwords Do Not Match!";
        }
        if (!filter_var($Input_Email, FILTER_VALIDATE_EMAIL))
        {
            $ErrorArrays[] = "Incorrect Email Formatting";
        }

        if (count($ErrorArrays) == 0)
        {
            // No Errors
        }
        else
        {
            foreach ($ErrorArrays AS $Errors)
            {
                echo "<font color='red'><b>".$Errors."</font></b><br>";
            }
        }
    }

?>

    <form method="POST"> 
        Username: <input type='text' name='Username'> <br>
        Password: <input type='password' name='Password'><br>
        Confirm Password: <input type='password' name='ConfirmPass'><br>
        Email: <input type='text' name='Email'> <br><br>

        <input type='submit' name='Register' value='Register'>


    </form> 

This is a very basic PHP Form validation. This could be put in a try block, but for basic reference, I see this fit following our conversation in the comment box.

What this script will do, is process each of the post elements, and act accordingly, for example:

    if (!filter_var($Input_Email, FILTER_VALIDATE_EMAIL))
        {
            $ErrorArrays[] = "Incorrect Email Formatting";
        }

This will check:

if $Input_Email is not a valid email. If this is not a valid E-mail, then a message will get added to a empty array.

Further down the script, you will see:

    if (count($ErrorArrays) == 0)
    {
        // No Errors
    }
    else
    {
        foreach ($ErrorArrays AS $Errors)
        {
            echo "<font color='red'><b>".$Errors."</font></b><br>";
        }
    }

Basically. if the array count is not 0, errors have been found. Then the script will print out the errors.

Remember, this is a reference based on our conversation in the comment box, and should be used as such.

sudo gem install --no-user-install <gem-name>

will install your gem globally, i.e. it will be available to all user's contexts.

you can solve it

sudo nano /etc/apache2/ports.conf

and changed Listen to 8080

Well, this question appears on top of search results, so I believe we need code example here. Here's the Python code:

import cv2

def apply_mask(frame, mask):
    """Apply binary mask to frame, return in-place masked image."""
    return cv2.bitwise_and(frame, frame, mask=mask)

Mask and frame must be the same size, so pixels remain as-is where mask is 1 and are set to zero where mask pixel is 0.

And for C++ it's a little bit different:

cv::Mat inFrame; // Original (non-empty) image
cv::Mat mask; // Original (non-empty) mask

// ...

cv::Mat outFrame;  // Result output
inFrame.copyTo(outFrame, mask);

Very simple methods Just go to the terminal and the type following

rails g devise:controllers users //This will create devise controllers in controllers/users folder

Next to use custom views

rails g devise:views users //This will create devise views in views/users folder

now in your route.rb file

devise_for :users, controllers: {
           :sessions => "users/sessions",
           :registrations => "users/registrations" }

You can add other controllers too. This will make devise to use controllers in users folder and views in users folder.

Now you can customize your views as your desire and add your logic to controllers in controllers/users folder. Enjoy !

In C++11, to_string is finally added to the standard.

This worked for me on UTC Timestamp (2020-08-19T09:12:57.945888)

for di, i in enumerate(df['YourColumnName']):
    df['YourColumnName'][di] = pd.Timestamp(i)

On your branch - say master, pull and allow unrelated histories

git pull origin master --allow-unrelated-histories

Worked for me.

The following works without flattening the folder structure:

gulp.src(['input/folder/**/*']).pipe(gulp.dest('output/folder'));

The '**/*' is the important part. That expression is a glob which is a powerful file selection tool. For example, for copying only .js files use: 'input/folder/**/*.js'

To add to an existing answer in ASP.NET Core >= 1.0 you can

return Unauthorized();

return Unauthorized(object value);

To pass info to the client you can do a call like this:

return Unauthorized(new { Ok = false, Code = Constants.INVALID_CREDENTIALS, ...});

On the client besides the 401 response you will have the passed data too. For example on most clients you can await response.json() to get it.

Check for the existence by retrieving its object_id:

if object_id('tempdb..##clients_keyword') is not null
    drop table ##clients_keyword

In Bootstrap, the .btn class has a white-space: nowrap; property, making it so that the button text won't wrap. So, after setting that to normal, and giving the button a width, the text should wrap to the next line if the text would exceed the set width.

#new-board-btn {
    white-space: normal;
}

Single quotes are characters (char), double quotes are null-terminated strings (char *).

char c = 'x';
char *s = "Hello World";

Adding an answer related to child_process.exec as I too had needed live feedback and wasn't getting any until after the script finished. This also supplements my comment to the accepted answer, but as it's formatted it will a bit more understandable and easier to read.

Basically, I have a npm script that calls Gulp, invoking a task which subsequently uses child_process.exec to execute a bash or batch script depending on the OS. Either script runs a build process via Gulp and then makes some calls to some binaries that work with the Gulp output.

It's exactly like the others (spawn, etc.), but for the sake of completion, here's exactly how to do it:

// INCLUDES
import * as childProcess from 'child_process'; // ES6 Syntax


// GLOBALS
let exec = childProcess.exec; // Or use 'var' for more proper 
                              // semantics, though 'let' is 
                              // true-to-scope


// Assign exec to a variable, or chain stdout at the end of the call
// to exec - the choice, yours (i.e. exec( ... ).stdout.on( ... ); )
let childProcess = exec
(
    './binary command -- --argument argumentValue',
    ( error, stdout, stderr ) =>
    {
        if( error )
        {
            // This won't show up until the process completes:
            console.log( '[ERROR]: "' + error.name + '" - ' + error.message );
            console.log( '[STACK]: ' + error.stack );

            console.log( stdout );
            console.log( stderr );
            callback();            // Gulp stuff
            return;
        }

        // Neither will this:
        console.log( stdout );
        console.log( stderr );
        callback();                // Gulp stuff
    }
);

Now its as simple as adding an event listener. For stdout:

childProcess.stdout.on
(
    'data',
    ( data ) =>
    {
        // This will render 'live':
        console.log( '[STDOUT]: ' + data );
    }
);

And for stderr:

childProcess.stderr.on
(
    'data',
    ( data ) =>
    {
        // This will render 'live' too:
        console.log( '[STDERR]: ' + data );
    }
);

Not too bad at all - HTH

The statement about CMake being a "build generator" is a common misconception.

It's not technically wrong; it just describes HOW it works, but not WHAT it does.

In the context of the question, they do the same thing: take a bunch of C/C++ files and turn them into a binary.

So, what is the real difference?

• CMake is much more high-level. It's tailored to compile C++, for which you write much less build code, but can be also used for general purpose build. make has some built-in C/C++ rules as well, but they are useless at best.

• CMake does a two-step build: it generates a low-level build script in ninja or make or many other generators, and then you run it. All the shell script pieces that are normally piled into Makefile are only executed at the generation stage. Thus, CMake build can be orders of magnitude faster.

• The grammar of CMake is much easier to support for external tools than make's.

• Once make builds an artifact, it forgets how it was built. What sources it was built from, what compiler flags? CMake tracks it, make leaves it up to you. If one of library sources was removed since the previous version of Makefile, make won't rebuild it.

• Modern CMake (starting with version 3.something) works in terms of dependencies between "targets". A target is still a single output file, but it can have transitive ("public"/"interface" in CMake terms) dependencies. These transitive dependencies can be exposed to or hidden from the dependent packages. CMake will manage directories for you. With make, you're stuck on a file-by-file and manage-directories-by-hand level.

You could code up something in make using intermediate files to cover the last two gaps, but you're on your own. make does contain a Turing complete language (even two, sometimes three counting Guile); the first two are horrible and the Guile is practically never used.

To be honest, this is what CMake and make have in common -- their languages are pretty horrible. Here's what comes to mind:

• They have no user-defined types;
• CMake has three data types: string, list, and a target with properties. make has one: string;
• you normally pass arguments to functions by setting global variables.
  • This is partially dealt with in modern CMake - you can set a target's properties: set_property(TARGET helloworld APPEND PROPERTY INCLUDE_DIRECTORIES "${CMAKE_CURRENT_SOURCE_DIR}");
• referring to an undefined variable is silently ignored by default;

This code is actually used to add values to the dictionary and through the data to an Array According to the Key.

NSMutableArray *arr = [[NSMutableArray alloc]init];
NSDictionary *dicto = [[NSMutableDictionary alloc]initWithObjectsAndKeys:@"Hello",@"StackOverFlow",@"Key1",@"StackExchange",@"Key2", nil];
NSLog(@"The dictonary is = %@", dicto);
arr = [dicto valueForKey:@"Key1"];
NSLog(@"The array is = %@", arr);

This stratify parameter makes a split so that the proportion of values in the sample produced will be the same as the proportion of values provided to parameter stratify.

For example, if variable y is a binary categorical variable with values 0 and 1 and there are 25% of zeros and 75% of ones, stratify=y will make sure that your random split has 25% of 0's and 75% of 1's.
