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

You need to set JDK 1.5 to your project and also all dependent project or jar file should also compiled with JDK 1.5

In Spring every request will go through the DispatcherServlet. To avoid Static file request through DispatcherServlet(Front contoller) we configure MVC Static content.

Spring 3.1. introduced the ResourceHandlerRegistry to configure ResourceHttpRequestHandlers for serving static resources from the classpath, the WAR, or the file system. We can configure the ResourceHandlerRegistry programmatically inside our web context configuration class.

• we have added the /js/** pattern to the ResourceHandler, lets include the foo.js resource located in the webapp/js/ directory
• we have added the /resources/static/** pattern to the ResourceHandler, lets include the foo.html resource located in the webapp/resources/ directory

@Configuration
@EnableWebMvc
public class StaticResourceConfiguration implements WebMvcConfigurer {

    @Override
    public void addResourceHandlers(ResourceHandlerRegistry registry) {
        System.out.println("WebMvcConfigurer - addResourceHandlers() function get loaded...");
        registry.addResourceHandler("/resources/static/**")
                .addResourceLocations("/resources/");

        registry
            .addResourceHandler("/js/**")
            .addResourceLocations("/js/")
            .setCachePeriod(3600)
            .resourceChain(true)
            .addResolver(new GzipResourceResolver())
            .addResolver(new PathResourceResolver());
    }
}

XML Configuration

<mvc:annotation-driven />
  <mvc:resources mapping="/staticFiles/path/**" location="/staticFilesFolder/js/"
                 cache-period="60"/>

Spring Boot MVC Static Content if the file is located in the WAR’s webapp/resources folder.

spring.mvc.static-path-pattern=/resources/static/**

Worked by lowering the spring boot starter parent to 1.5.13

<parent>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-parent</artifactId>
    <version>1.5.13.RELEASE</version>
    <relativePath/> <!-- lookup parent from repository -->
</parent>

The main problem here is content type [text/html;charset=iso-8859-1] received from the service, however the real content type should be application/json;charset=iso-8859-1

In order to overcome this you can introduce custom message converter. and register it for all kind of responses (i.e. ignore the response content type header). Just like this

List<HttpMessageConverter<?>> messageConverters = new ArrayList<HttpMessageConverter<?>>();        
//Add the Jackson Message converter
MappingJackson2HttpMessageConverter converter = new MappingJackson2HttpMessageConverter();

// Note: here we are making this converter to process any kind of response, 
// not only application/*json, which is the default behaviour
converter.setSupportedMediaTypes(Collections.singletonList(MediaType.ALL));        
messageConverters.add(converter);  
restTemplate.setMessageConverters(messageConverters); 

I was having the exact same problem. In my case none of the above solutions worked, what did it for me was to add the following:

app.UseCors(builder => builder
.AllowAnyOrigin()
.AllowAnyMethod()
.AllowAnyHeader()

So basically, allow everything.

Bear in mind that this is safe only if running locally.

import org.junit.Test;
import org.junit.runner.RunWith;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.boot.test.autoconfigure.orm.jpa.DataJpaTest;
import org.springframework.boot.test.autoconfigure.web.servlet.AutoConfigureWebMvc;
import org.springframework.boot.test.context.SpringBootTest;
import org.springframework.test.context.junit4.SpringRunner;



@RunWith(SpringRunner.class)
@DataJpaTest
@SpringBootTest
@AutoConfigureWebMvc
public class RepoTest {

    @Autowired
    private ThingShiftDetailsRepository thingShiftDetailsRepo;

    @Test
    public void findThingShiftDetails() {
            ShiftDetails details = new ShiftDetails();
            details.setThingId(1);

            thingShiftDetailsRepo.save(details);

            ShiftDetails dbDetails = thingShiftDetailsRepo.findByThingId(1);
            System.out.println(dbDetails);
    }
}

Above annotations worked well for me. I am using spring boot with JPA.

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.

I updated with /configuration/** and /swagger-resources/** and it worked for me.

@Override
public void configure(WebSecurity web) throws Exception {
    web.ignoring().antMatchers("/v2/api-docs", "/configuration/ui", "/swagger-resources/**", "/configuration/**", "/swagger-ui.html", "/webjars/**");

}

I had the same problem on a methood that returns the status of the server. The application is deployed on multiple servers. So the easiest I found is to add

@CrossOrigin(origins = "*")
@RequestMapping(value="/schedulerActive")
public String isSchedulerActive(){
  //code goes here
}

This method is not secure but you can add allowCredentials for that.

In my case, I had to do the following while running with Junit5

@SpringBootTest(classes = {abc.class}) @ExtendWith(SpringExtension.class

Here abc.class was the class that was being tested

If you are using Spring Security ver >= 4.2 you can use Spring Security's native support instead of including Apache's:

@Configuration
@EnableWebMvc
public class WebConfig extends WebMvcConfigurerAdapter {

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

The example above was copied from a Spring blog post in which you also can find information about how to configure CORS on a controller, specific controller methods, etc. Moreover, there is also XML configuration examples as well as Spring Boot integration.

In Spring properties files, you can't just specify a number for this property. You also need to specify a unit. So you can say spring.mvc.async.request-timeout=5000ms or spring.mvc.async.request-timeout=5s, both of which will give you a 5-second timeout.

These are the attributes I used to get video to autoplay on Chrome - onloadedmetadata="this.muted = true", playsinline, autoplay, muted, loop

Example:

<video src="path/to/video.mp4" onloadedmetadata="this.muted = true" playsinline autoplay muted loop></video>

From stack trace:

HikariPool: Timeout failure pool HikariPool-0 stats (total=20, active=20, idle=0, waiting=0) Means pool reached maximum connections limit set in configuration.

The next line: HikariPool-0 - Connection is not available, request timed out after 30000ms. Means pool waited 30000ms for free connection but your application not returned any connection meanwhile.

Mostly it is connection leak (connection is not closed after borrowing from pool), set leakDetectionThreshold to the maximum value that you expect SQL query would take to execute.

otherwise, your maximum connections 'at a time' requirement is higher than 20 !

Check for the name of the

templates

folder. it should be templates not template(without s).

I had exact same error, I was not giving base package. Giving correct base package,ressolved it.

package com.ymc.backend.ymcbe;

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.context.annotation.ComponentScan;

@SpringBootApplication
@ComponentScan(basePackages="com.ymc.backend")
public class YmcbeApplication {

    public static void main(String[] args) {
        SpringApplication.run(YmcbeApplication.class, args);
    }

}

Note: not including .controller @ComponentScan(basePackages="com.ymc.backend.controller") because i have many other component classes which my project does not scan if i just give .controller

Here is my controller sample:

package com.ymc.backend.controller;

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.web.bind.annotation.CrossOrigin;
import org.springframework.web.bind.annotation.PostMapping;
import org.springframework.web.bind.annotation.RequestBody;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RestController;


@RestController
@CrossOrigin
@RequestMapping(value = "/user")
public class UserController {

    @PostMapping("/sendOTP")
    public String sendOTP() {
        return "OTP sent";
    };


}

To add on to Andrea's solution, if you are passing an array of JSONs for instance

[
    {"name":"value"},
    {"name":"value2"}
]

Then you will need to set up the Spring Boot Controller like so:

@RequestMapping(
    value = "/process", 
    method = RequestMethod.POST)
public void process(@RequestBody Map<String, Object>[] payload) 
    throws Exception {

    System.out.println(payload);

}

First enable mod_headers on your server, then you can use header directive in both Apache conf and .htaccess.

1. enable mod_headers

• a2enmod headers

2. configure header in .htaccess file

• Header add Access-Control-Allow-Origin "*"
• Header add Access-Control-Allow-Headers "origin, x-requested-with, content-type"
• Header add Access-Control-Allow-Methods "PUT, GET, POST, DELETE, OPTIONS"

Below worked for me..

import static org.springframework.test.web.servlet.request.MockMvcRequestBuilders.get;
import static org.springframework.test.web.servlet.result.MockMvcResultHandlers.print;
import static org.springframework.test.web.servlet.result.MockMvcResultMatchers.status;

import org.apache.catalina.security.SecurityConfig;
import org.junit.Before;
import org.junit.Test;

import org.springframework.context.annotation.ComponentScan;
import org.springframework.data.jpa.repository.config.EnableJpaRepositories;
import org.springframework.test.context.junit4.SpringRunner;
import org.springframework.test.context.web.WebAppConfiguration;
import org.springframework.test.web.servlet.MockMvc;
import org.springframework.test.web.servlet.setup.MockMvcBuilders;
import org.springframework.web.context.WebApplicationContext;

import com.something.configuration.SomethingConfig;

@RunWith(SpringRunner.class)
@SpringBootTest(classes = { SomethingConfig.class, SecurityConfig.class }) //All your configuration classes
@EnableAutoConfiguration
@WebAppConfiguration // for MVC configuration
@EnableJpaRepositories("com.something.persistence.dataaccess")  //JPA repositories
@EntityScan("com.something.domain.entity.*")  //JPA entities
@ComponentScan("com.something.persistence.fixture") //any component classes you have
public class SomethingApplicationTest {

    @Autowired
    private WebApplicationContext ctx;
    private MockMvc mockMvc;

    @Before
    public void setUp() {
        this.mockMvc = MockMvcBuilders.webAppContextSetup(ctx).build();
    }

    @Test
    public void loginTest() throws Exception {
        this.mockMvc.perform(get("/something/login"))
        .andDo(print()).andExpect(status().isOk());
    }

}

My return object didn't have @XmlRootElement annotation on the class. Adding the annotation solved my issue.

@XmlRootElement(name = "ReturnObjectClass")
public class ReturnObjectClass {

    @XmlElement(name = "Status", required = true)
    protected StatusType status;
    //...
}

I know the question asking for Spring boot, but I believe lot of people looking for how to do this in non Spring boot, like me searching almost whole day.

Above Spring 4, there is no need to configure MappingJacksonHttpMessageConverter if you only intend to configure ObjectMapper.

You just need to do:

public class MyObjectMapper extends ObjectMapper {

    private static final long serialVersionUID = 4219938065516862637L;

    public MyObjectMapper() {
        super();
        enable(SerializationFeature.INDENT_OUTPUT);
    }       
}

And in your Spring configuration, create this bean:

@Bean 
public MyObjectMapper myObjectMapper() {        
    return new MyObjectMapper();
}

For Ubunutu 18.04 inside a vagrant box ... This is what helped me

1. Ensure www-data has permissions to the .htaccess file

     
       sudo chown www-data.www-data .htaccess
     
   

2. edit the apache2 conf to allow for symlinks etc

     
       sudo nano /etc/apache2/apache2.conf
     
   

   Add this to the file

<Directory /var/www/html/>_x000D_
  Options Indexes FollowSymLinks_x000D_
  AllowOverride all_x000D_
  Require all granted_x000D_
</Directory>

3. Restart your apache2 server

   sudo service apache2 restart

I hope this helps someone.

1. index.html file should come under below location - src/resources/public/index.html OR src/resources/static/index.html if both location defined then which first occur index.html will call from that directory.

2. The source code looks like -

   package com.bluestone.pms.app.boot; 
   import org.springframework.boot.Banner;
   import org.springframework.boot.Banner;
   import org.springframework.boot.SpringApplication;
   import org.springframework.boot.autoconfigure.EnableAutoConfiguration;
   import org.springframework.boot.autoconfigure.SpringBootApplication;
   import org.springframework.boot.builder.SpringApplicationBuilder;
   import org.springframework.boot.web.support.SpringBootServletInitializer;
   import org.springframework.context.annotation.ComponentScan;
   
   
   
   @SpringBootApplication 
   @EnableAutoConfiguration
   @ComponentScan(basePackages = {"com.your.pkg"}) 
   public class BootApplication extends SpringBootServletInitializer {
   
   
   
   /**
    * @param args Arguments
   */
   public static void main(String[] args) {
   SpringApplication application = new SpringApplication(BootApplication.class);
   /* Setting Boot banner off default value is true */
   application.setBannerMode(Banner.Mode.OFF);
   application.run(args);
   }
   
   /**
     * @param builder a builder for the application context
     * @return the application builder
     * @see SpringApplicationBuilder
    */
    @Override
    protected SpringApplicationBuilder configure(SpringApplicationBuilder 
     builder) {
       return super.configure(builder);
      }
   }
   

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>

Project ? Properties ? Target Runtimes ? *Apache Tomcat worked for me. There is no Target Runtimes under Facets (I'm on Eclipse v4.4 (Luna)).

Old post, but I thought I would share my solution because there aren't many solutions out there for this issue.

If you're running an old Windows Server 2003 machine, you likely need to install a hotfix (KB938397).

This problem occurs because the Cryptography API 2 (CAPI2) in Windows Server 2003 does not support the SHA2 family of hashing algorithms. CAPI2 is the part of the Cryptography API that handles certificates.

https://support.microsoft.com/en-us/kb/938397

For whatever reason, Microsoft wants to email you this hotfix instead of allowing you to download directly. Here's a direct link to the hotfix from the email:

http://hotfixv4.microsoft.com/Windows Server 2003/sp3/Fix200653/3790/free/315159_ENU_x64_zip.exe

Look at the exception:

No qualifying bean of type [edu.java.spring.ws.dao.UserDao] found for dependency

This means that there's no bean available to fulfill that dependency. Yes, you have an implementation of the interface, but you haven't created a bean for that implementation. You have two options:

• Annotate UserDaoImpl with @Component or @Repository, and let the component scan do the work for you, exactly as you have done with UserService.
• Add the bean manually to your xml file, the same you have done with UserBoImpl.

Remember that if you create the bean explicitly you need to put the definition before the component scan. In this case the order is important.

The user "geoand" is right in pointing out the reasons here and giving a solution. But a better approach is to encapsulate your configuration into a separate class, say SystemContiguration java class and then inject this class into what ever services you want to use those fields.

Your current way(@grahamrb) of reading config values directly into services is error prone and would cause refactoring headaches if config setting name is changed.

Spring boot doc 'was' wrong (they have since fixed it) :

To switch it off you can set error.whitelabel.enabled=false

should be

To switch it off you can set server.error.whitelabel.enabled=false

The accepted answer to this question is awesome and should remain the accepted answer. However I ran into an issue with the code where the read stream was not always being ended/closed. Part of the solution was to send autoClose: true along with start:start, end:end in the second createReadStream arg.

The other part of the solution was to limit the max chunksize being sent in the response. The other answer set end like so:

var end = positions[1] ? parseInt(positions[1], 10) : total - 1;

...which has the effect of sending the rest of the file from the requested start position through its last byte, no matter how many bytes that may be. However the client browser has the option to only read a portion of that stream, and will, if it doesn't need all of the bytes yet. This will cause the stream read to get blocked until the browser decides it's time to get more data (for example a user action like seek/scrub, or just by playing the stream).

I needed this stream to be closed because I was displaying the <video> element on a page that allowed the user to delete the video file. However the file was not being removed from the filesystem until the client (or server) closed the connection, because that is the only way the stream was getting ended/closed.

My solution was just to set a maxChunk configuration variable, set it to 1MB, and never pipe a read a stream of more than 1MB at a time to the response.

// same code as accepted answer
var end = positions[1] ? parseInt(positions[1], 10) : total - 1;
var chunksize = (end - start) + 1;

// poor hack to send smaller chunks to the browser
var maxChunk = 1024 * 1024; // 1MB at a time
if (chunksize > maxChunk) {
  end = start + maxChunk - 1;
  chunksize = (end - start) + 1;
}

This has the effect of making sure that the read stream is ended/closed after each request, and not kept alive by the browser.

I also wrote a separate StackOverflow question and answer covering this issue.

Spring Data JPA by default looks for an EntityManagerFactory named entityManagerFactory. Check out this part of the Javadoc of EnableJpaRepositories or Table 2.1 of the Spring Data JPA documentation.

That means that you either have to rename your emf bean to entityManagerFactory or change your Spring configuration to:

<jpa:repositories base-package="your.package" entity-manager-factory-ref="emf" /> 

(if you are using XML)

or

@EnableJpaRepositories(basePackages="your.package", entityManagerFactoryRef="emf")

(if you are using Java Config)

Java 8 supports default methods in interfaces. And in JDK 8 a lot of old interfaces now have new default methods. For example, now in CharSequence we have chars and codePoints methods.
If source level of your project is lower than 1.8, then compiler doesn't allow you to use default methods in interfaces. So it cannot compile classes that directly on indirectly depend on this interfaces.
If I get your problem right, then you have two solutions. First solution is to rollback to JDK 7, then you will use old CharSequence interface without default methods. Second solution is to set source level of your project to 1.8, then your compiler will not complain about default methods in interfaces.

There are many different versions of mail around. When you go beyond mail -s subject to1@address1 to2@address2

• With some mailx implementations, e.g. from mailutils on Ubuntu or Debian's bsd-mailx, it's easy, because there's an option for that.

  mailx -a 'Content-Type: text/html' -s "Subject" to@address <test.html
  

• With the Heirloom mailx, there's no convenient way. One possibility to insert arbitrary headers is to set editheaders=1 and use an external editor (which can be a script).

  ## Prepare a temporary script that will serve as an editor.
  
  ## This script will be passed to ed.
  temp_script=$(mktemp)
  cat <<'EOF' >>"$temp_script"
  1a
  Content-Type: text/html
  .
  $r test.html
  w
  q
  EOF
  ## Call mailx, and tell it to invoke the editor script
  EDITOR="ed -s $temp_script" heirloom-mailx -S editheaders=1 -s "Subject" to@address <<EOF
  ~e
  .
  EOF
  rm -f "$temp_script"
  

• With a general POSIX mailx, I don't know how to get at headers.

If you're going to use any mail or mailx, keep in mind that

• This isn't portable even within a given Linux distribution. For example, both Ubuntu and Debian have several alternatives for mail and mailx.

• When composing a message, mail and mailx treats lines beginning with ~ as commands. If you pipe text into mail, you need to arrange for this text not to contain lines beginning with ~.

If you're going to install software anyway, you might as well install something more predictable than mail/Mail/mailx. For example, mutt. With Mutt, you can supply most headers in the input with the -H option, but not Content-Type, which needs to be set via a mutt option.

mutt -e 'set content_type=text/html' -s 'hello' 'to@address' <test.html

Or you can invoke sendmail directly. There are several versions of sendmail out there, but they all support sendmail -t to send a mail in the simplest fashion, reading the list of recipients from the mail. (I think they don't all support Bcc:.) On most systems, sendmail isn't in the usual $PATH, it's in /usr/sbin or /usr/lib.

cat <<'EOF' - test.html | /usr/sbin/sendmail -t

The solution of this problem is really very simple. actually Google start using a new authorization mechanism for its User.. you might have seen another line in debug console prompting you to log into your account using any browser.! this is because of new XOAUTH2 authentication mechanism which google start using since 2014. remember.. do not use the ssl over port 465, instead go for tls over 587. this is just because of XOAUTH2 authentication mechanism. if you use ssl over 465, your request will be bounced back.

what you really need to do is .. log into your google account and open up following address https://www.google.com/settings/security/lesssecureapps and check turn on . you have to do this for letting you to connect with the google SMTP because according to new authentication mechanism google bounce back all the requests from all those applications which does not follow any standard encryption technique.. after checking turn on.. you are good to go.. here is the code which worked fine for me..

require_once 'C:\xampp\htdocs\email\vendor\autoload.php';

define ('GUSER','[email protected]');
define ('GPWD','your password');


// make a separate file and include this file in that. call this function in that file.

function smtpmailer($to, $from, $from_name, $subject, $body) { 
    global $error;
    $mail = new PHPMailer();  // create a new object
    $mail->IsSMTP(); // enable SMTP
    $mail->SMTPDebug = 2;  // debugging: 1 = errors and messages, 2 = messages only
    $mail->SMTPAuth = true;  // authentication enabled
    $mail->SMTPSecure = 'tls'; // secure transfer enabled REQUIRED for GMail
    $mail->SMTPAutoTLS = false;
    $mail->Host = 'smtp.gmail.com';
    $mail->Port = 587;

    $mail->Username = GUSER;  
    $mail->Password = GPWD;           
    $mail->SetFrom($from, $from_name);
    $mail->Subject = $subject;
    $mail->Body = $body;
    $mail->AddAddress($to);
    if(!$mail->Send()) {
        $error = 'Mail error: '.$mail->ErrorInfo; 
        return false;
    } else {
        $error = 'Message sent!';
        return true;
    }
}

If on Windows and installed using chocolatey make sure firewall is allowing the default ports for it:

netsh advfirewall firewall add rule name="RabbitMQ Management" dir=in action=allow protocol=TCP localport=15672
netsh advfirewall firewall add rule name="RabbitMQ" dir=in action=allow protocol=TCP localport=5672

for the remote access.

You cannot show an alert from a controller. There is one way communication from the client to the server.The server can therefore not tell the client to do anything. The client requests and the server gives a response.

You therefore need to use javascript when the response returns to show a messagebox of some sort.

OR

using jquery on the button that calls the controller action

<script>
 $(document).ready(function(){
  $("#submitButton").on("click",function()
  {
   alert('Your Message');
  });

});
<script>

this work with spring boot 2.0.0

replace

  <dependency>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-tomcat</artifactId>
    <scope>provided</scope>
        </dependency>

with

<dependency>
<groupId>org.apache.tomcat.embed</groupId>
<artifactId>tomcat-embed-core</artifactId>
<version>9.0.6</version>
    </dependency>

Update: This will create a second context same as in applicationContext.xml

or you can add this code snippet to your web.xml

<servlet>
    <servlet-name>spring-dispatcher</servlet-name>
    <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
        <init-param>
          <param-name>contextConfigLocation</param-name>
          <param-value>classpath:applicationContext.xml</param-value>
        </init-param>
    <load-on-startup>1</load-on-startup>
</servlet>

instead of

<servlet>
    <servlet-name>dispatcher</servlet-name>
    <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
    <load-on-startup>1</load-on-startup>
</servlet>

Since no answer is accepted, I would like to provide one possible solution. If your script is written on Windows and uploaded to a Linux server(through FTP), then the problem will raise usually. The reason is that Windows uses CRLF to end each line while Linux uses LF. So you should convert it from CRLF to LF with the help of an editor, such Atom, as following

I am using gradle, met seem issue when I have a commandLineRunner consumes kafka topics and a health check endpoint for receiving incoming hooks. I spent 12 hours to figure out, finally found that I used mybatis-spring-boot-starter with spring-boot-starter-web, and they have some conflicts. Latter I directly introduced mybatis-spring, mybatis and spring-jdbc rather than the mybatis-spring-boot-starter, and the program worked well.

hope this helps

did you try 'localhost/phpmyadmin' ? (notice the lowercase)

PHPMyAdmin tends to have inconsistent directory names across its versions/distributions.

Edit: Confirm the URL by checking the name of the root folder!

If the config was the primary issue (and it may still be nthary) you would get a php error, not a http "Object not found" error,

As for the config error, here are some steps to correct it:

1. Once you have confirmed which case your PHPMyAdmin is in, confirm that your config.inc.php is located in its root directory.

2. If it is, rename it to something else as a backup. Then copy the config.sample.inc.php (in the same directory) and rename it to config.inc.php

3. Check if it works.

4. If its does, then open up both the new config.inc.php (that works) and the backup you took earlier of your old one. Compare them and copy/replace the important parts that you want to carry over, the file (in its default state) isn't that long and it should be relatively easy to do so.

N.B. If the reason that you want your old config is because of security setup that you once had, I would definitely suggest still using the security wizard built into XAMPP so that you can be assured that you have the right configuration for the right version. There is no guarantee that different XAMPP/PHPMyAdmin versions implement security/anything in the same way.

XAMPP Security Wizard

In Windows, if you have mapped network drives and you don't know the UNC path for them, you can start a command prompt (Start ? Run ? cmd.exe) and use the net use command to list your mapped drives and their UNC paths:

C:\>net use
New connections will be remembered.

Status       Local     Remote                    Network

-------------------------------------------------------------------------------
OK           Q:        \\server1\foo             Microsoft Windows Network
OK           X:        \\server2\bar             Microsoft Windows Network
The command completed successfully.

Note that this shows the list of mapped and connected network file shares for the user context the command is run under. If you run cmd.exe under your own user account, the results shown are the network file shares for yourself. If you run cmd.exe under another user account, such as the local Administrator, you will instead see the network file shares for that user.

Although it's too late , But here is my experience .

Whenever you get your maven project from a source controller or just copying your project from one machine to another , you need to update the dependencies .

For this Right-click on Project on project explorer -> Maven -> Update Project.

Please consider checking the "Force update of snapshot/releases" checkbox.

If you have not your dependencies in m2/repository then you need internet connection to get from the remote maven repository.

In case you have get from the source controller and you have not any unit test , It's probably your test folder does not include in the source controller in the first place , so you don't have those in the new repository.so you need to create those folders manually.

I have had both these cases .

In my case Codec ID of mp4 file was the issue, Codec ID: isom (isom/iso2/avc1/mp41) was not playing in IE 10 and 11 using video tag, after I converted it to "mp42 (mp42/isom/avc1)" using FFmpeg it started playing in IE as well.

I had a similar issue, no videos would play in Chrome. Tried installing beta 64bit, going back to Chrome 32bit release.

The only thing that worked for me was updating my video drivers.

I have the NVIDIA GTS 240. Downloaded, installed the drivers and restarted and Chrome 38.0.2125.77 beta-m (64-bit) starting playing HTML5 videos again on youtube, vimeo and others. Hope this helps anyone else.

This sounds like a ClassLoader conflict. I'd bet you have the javax.persistence api 1.x on the classpath somewhere, whereas Spring is trying to access ValidationMode, which was only introduced in JPA 2.0.

Since you use Maven, do mvn dependency:tree, find the artifact:

<dependency>
    <groupId>javax.persistence</groupId>
    <artifactId>persistence-api</artifactId>
    <version>1.0</version>
</dependency>

And remove it from your setup. (See Excluding Dependencies)

AFAIK there is no such general distribution for JPA 2, but you can use this Hibernate-specific version:

<dependency>
    <groupId>org.hibernate.javax.persistence</groupId>
    <artifactId>hibernate-jpa-2.0-api</artifactId>
    <version>1.0.1.Final</version>
</dependency>

OK, since that doesn't work, you still seem to have some JPA-1 version in there somewhere. In a test method, add this code:

System.out.println(EntityManager.class.getProtectionDomain()
                                      .getCodeSource()
                                      .getLocation());

See where that points you and get rid of that artifact.

Ahh, now I finally see the problem. Get rid of this:

<dependency>
    <groupId>org.springframework</groupId>
    <artifactId>spring-jpa</artifactId>
    <version>2.0.8</version>
</dependency>

and replace it with

<dependency>
    <groupId>org.springframework</groupId>
    <artifactId>spring-orm</artifactId>
    <version>3.2.5.RELEASE</version>
</dependency>

On a different note, you should set all test libraries (spring-test, easymock etc.) to

<scope>test</scope>

The answer to the above question is "none of the above". When you download new STS it won't support the old Spring Boot parent version. Just update parent version with latest comes with STS it will work.

<parent>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-parent</artifactId>
    <version>1.5.8.RELEASE</version>
    <relativePath/> <!-- lookup parent from repository -->
</parent>

If you have problem getting the latest, just create a new Spring Starter Project. Go to File->New->Spring Start Project and create a demo project you will get the latest parent version, change your version with that all will work. I do this every time I change STS.

You need to stop the server before re-launching. Look for the red box icon or server view.

First of all you missed ScriptService attribute to add in webservice.

[ScriptService]

After then try following method to call webservice via JSON.

        var webAddr = "http://Domain/VBRService.asmx/callJson";
        var httpWebRequest = (HttpWebRequest)WebRequest.Create(webAddr);
        httpWebRequest.ContentType = "application/json; charset=utf-8";
        httpWebRequest.Method = "POST";            

        using (var streamWriter = new StreamWriter(httpWebRequest.GetRequestStream()))
        {
            string json = "{\"x\":\"true\"}";

            streamWriter.Write(json);
            streamWriter.Flush();
        }

        var httpResponse = (HttpWebResponse)httpWebRequest.GetResponse();
        using (var streamReader = new StreamReader(httpResponse.GetResponseStream()))
        {
            var result = streamReader.ReadToEnd();
            return result;
        }

• Solution 1: Sometimes the build fails because, the target folder cannot be deleted. (It might be open in the backend due to the previous builds.)

  -> Open Task Manager

  -> In the Process tab

  -> Do "End Process" for the running "java.exe" processess

• Solution 2:

  -> Restart eclipse

  -> Perform Maven Build with command : clean install -DSkipTests

I had same problem - make sure the url for video asset is coming from secure domain. Our dev environment is http while production is secure. Due to the video being referenced via relative path, it wasn't working on development. Seems to be an issue that apple requires video to be secure...

The thing is that both the application context and the web application context are registered in the WebApplicationContext during server startup. When you run the test you must explicitly tell which contexts to load.

Try this:

@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration(locations = {"classpath:/beans.xml", "/mvc-dispatcher-servlet.xml"})

In my case, the error was valid and it was due to using try with resource

 try (ConfigurableApplicationContext cxt = new ClassPathXmlApplicationContext(
                    "classpath:application-main-config.xml")) {..
}

It auto closes the stream which should not happen if I want to reuse this context in other beans.

Display Your Video First Frame as Thumbnail:

Add preload="metadata" to your video tag and the second of the first frame #t=0.5 to your video source:

<video width="400" controls="controls" preload="metadata">_x000D_
  <source src="https://www.w3schools.com/html/mov_bbb.mp4#t=0.5" type="video/mp4">_x000D_

First you have to check if FileZilla is running on xampp control panel Than such error can occur You have to stop the FileZilla service from Xampp control panel

Necro'ing this Question ;)

You need to change the data being sent as Stringified JSON, that way you can modularize the Ajax call into a single supportable function.

First Step: Extract data construction

/***
 * This helper is used to call WebMethods from the page WebMethods.aspx
 * 
 * @method - String value; the name of the Web Method to execute
 * @data - JSON Object; the JSON structure data to pass, it will be Stringified
 *      before sending
 * @beforeSend - Function(xhr, sett)
 * @success - Function(data, status, xhr)
 * @error - Function(xhr, status, err)
 */
function AddToCartAjax(method, data, beforeSend, success, error) {
    $.ajax({
        url: 'AddToCart.aspx/', + method,
        data: JSON.stringify(data),
        type: "POST",
        dataType: "json",
        contentType: "application/json; charset=utf-8",
        beforeSend: beforeSend,
        success: success,
        error: error
    })
}

Second Step: Generalize WebMethod

[WebMethod]
public static string AddTo_Cart ( object items ) {
    var js = new JavaScriptSerializer();
    var json = js.ConvertToType<Dictionary<string , int>>( items );

    SpiritsShared.ShoppingCart.AddItem(json["itemId"], json["quantity"]);      
    return "Add";
}

Third Step: Call it where you need it

This can be called just about anywhere, JS-file, HTML-file, or Server-side construction.

var items = { "quantity": total_qty, "itemId": itemId };

AddToCartAjax("AddTo_Cart", items,
    function (xhr, sett) {  // @beforeSend
        alert("Start!!!");
    }, function (data, status, xhr) {   // @success
        alert("a");
    }, function(xhr, status, err){  // @error
        alert("Sorry!!!");
    });

For those who stuck at this error as me and nothing helped from above: check if problem folder from error.log actually exists on your server. Mine was generated automatically by Django in wrong place (was messed with static root, then manage.py collectstatic). Have no idea why one can not name errors correctly.

Just return object: it will be parser to JSON.

public Object Get(string id)
{
    return new { id = 1234 };
}

This hasn't solved my problem too, so I changed the parameters slightly.
This code worked for me:

var dataValue = "{ name: 'person', isGoing: 'true', returnAddress: 'returnEmail' }";

$.ajax({
    type: "POST",
    url: "Default.aspx/OnSubmit",
    data: dataValue,
    contentType: 'application/json; charset=utf-8',
    dataType: 'json',
    error: function (XMLHttpRequest, textStatus, errorThrown) {
        alert("Request: " + XMLHttpRequest.toString() + "\n\nStatus: " + textStatus + "\n\nError: " + errorThrown);
    },
    success: function (result) {
        alert("We returned: " + result.d);
    }
});

It's better if you check visibility like this: if($('#video-over').is(':visible'))

Deleting all files from bin and then rebuilding the solution worked for me.

Use Message.get_payload

b = email.message_from_string(a)
if b.is_multipart():
    for payload in b.get_payload():
        # if payload.is_multipart(): ...
        print payload.get_payload()
else:
    print b.get_payload()

For XAMPP on Mac

sudo chmod -R 0777 /Applications/XAMPP/xamppfiles/htdocs/myprojectname

NOTE: remember to change 'myprojectname' to your actual project name. Also, make sure the project is on the root directory of htdocs or change the path accordingly.

• Download maven compiler plugin jar from your central repositoy n try
• If it is still failing check your jdk version, it is because of your application is built on diff jdk version

Try autoplay="autoplay" instead of the "true" value. That's the documented way to enable autoplay. That sounds weirdly redundant, I know.

Here's an example that will center the content within the parent div. This also makes sure the overlay starts at the edge of the video, even when centered.

<div class="outer-container">
    <div class="inner-container">
        <div class="video-overlay">Bug Buck Bunny - Trailer</div>
        <video id="player" src="http://video.webmfiles.org/big-buck-bunny_trailer.webm" controls autoplay loop></video>
    </div>
</div>

with css as

.outer-container {
    border: 1px dotted black;
    width: 100%;
    height: 100%;
    text-align: center;
}
.inner-container {
    border: 1px solid black;
    display: inline-block;
    position: relative;
}
.video-overlay {
    position: absolute;
    left: 0px;
    top: 0px;
    margin: 10px;
    padding: 5px 5px;
    font-size: 20px;
    font-family: Helvetica;
    color: #FFF;
    background-color: rgba(50, 50, 50, 0.3);
}
video {
    width: 100%;
    height: 100%;
}

I'm answering on specific to this error code(08s01).

usually, MySql close socket connections are some interval of time that is wait_timeout defined on MySQL server-side which by default is 8hours. so if a connection will timeout after this time and the socket will throw an exception which SQLState is "08s01".

1.use connection pool to execute Query, make sure the pool class has a function to make an inspection of the connection members before it goes time_out.

2.give a value of <wait_timeout> greater than the default, but the largest value is 24 days

3.use another parameter in your connection URL, but this method is not recommended, and maybe deprecated.

EfCore version of @JonSchneider's answer

myDbContext.Database.SetCommandTimeout(999);

Where myDbContext is your DbContext instance, and 999 is the timeout value in seconds.

(Syntax current as of Entity Framework Core 3.1)

I found a much simpler alternative way to generating soap message. Given a Person Object:

import com.fasterxml.jackson.annotation.JsonInclude;

@JsonInclude(JsonInclude.Include.NON_NULL)
public class Person {
  private String name;
  private int age;
  private String address; //setter and getters below
}

Below is a simple Soap Message Generator:

import com.fasterxml.jackson.databind.DeserializationFeature;
import com.fasterxml.jackson.databind.ObjectMapper;
import com.fasterxml.jackson.databind.SerializationFeature;
import com.fasterxml.jackson.datatype.jsr310.JavaTimeModule;
import lombok.extern.slf4j.Slf4j;
import org.apache.commons.lang3.StringUtils;
import com.fasterxml.jackson.dataformat.xml.XmlMapper;

@Slf4j
public class SoapGenerator {

  protected static final ObjectMapper XML_MAPPER = new XmlMapper()
      .enable(DeserializationFeature.READ_UNKNOWN_ENUM_VALUES_AS_NULL)
      .configure(DeserializationFeature.FAIL_ON_UNKNOWN_PROPERTIES, false)
      .configure(SerializationFeature.WRITE_DATES_AS_TIMESTAMPS, false)
      .registerModule(new JavaTimeModule());

  private static final String SOAP_BODY_OPEN = "<soap:Body>";
  private static final String SOAP_BODY_CLOSE = "</soap:Body>";
  private static final String SOAP_ENVELOPE_OPEN = "<soap:Envelope xmlns:soap=\"http://schemas.xmlsoap.org/soap/envelope/\">";
  private static final String SOAP_ENVELOPE_CLOSE = "</soap:Envelope>";

  public static String soapWrap(String xml) {
    return SOAP_ENVELOPE_OPEN + SOAP_BODY_OPEN + xml + SOAP_BODY_CLOSE + SOAP_ENVELOPE_CLOSE;
  }

  public static String soapUnwrap(String xml) {
    return StringUtils.substringBetween(xml, SOAP_BODY_OPEN, SOAP_BODY_CLOSE);
  }
}

You can use by:

 public static void main(String[] args) throws Exception{
        Person p = new Person();
        p.setName("Test");
        p.setAge(12);

        String xml = SoapGenerator.soapWrap(XML_MAPPER.writeValueAsString(p));
        log.info("Generated String");
        log.info(xml);
      }

Probably the string would be like this data:image/jpeg;base64,/9j/4QN8RXh... First split for / and get the second token.

var StrAfterSlash = Face.Split('/')[1];

Then Split for ; and get the first token which will be the format. In my case it's jpeg.

var ImageFormat =StrAfterSlash.Split(';')[0];

Then remove the line data:image/jpeg;base64, for the collected format

CleanFaceData=Face.Replace($"data:image/{ImageFormat };base64,",string.Empty);

I also had same error but with codeigniter application. I changed

• my base URL in config.php to my localhost path

• in htaccess I changed RewriteBase /"my folder name in htdocs"

  and I able to login to my application.

Hope it might help.

If you are getting this error with a Java configuration, it is usually because you forget to pass in the application context to the DispatcherServlet constructor:

AnnotationConfigWebApplicationContext ctx = new AnnotationConfigWebApplicationContext();
ctx.register(WebConfig.class);

ServletRegistration.Dynamic dispatcher = sc.addServlet("dispatcher", 
    new DispatcherServlet()); // <-- no constructor args!
dispatcher.setLoadOnStartup(1);
dispatcher.addMapping("/*");

Fix it by adding the context as the constructor arg:

AnnotationConfigWebApplicationContext ctx = new AnnotationConfigWebApplicationContext();
ctx.register(WebConfig.class);

ServletRegistration.Dynamic dispatcher = sc.addServlet("dispatcher", 
    new DispatcherServlet(ctx)); // <-- hooray! Spring doesn't look for XML files!
dispatcher.setLoadOnStartup(1);
dispatcher.addMapping("/*");

THE CORRECT WAY IS :

UPDATE test1
INNER JOIN test2 ON (test1.id = test2.id)
SET test1.data = test2.data

change your code to:

function ChangePurpose(Vid, PurId) {
    var Success = false;
    $.ajax({
        type: "POST",
        url: "CHService.asmx/SavePurpose",
        dataType: "text",
        async: false,
        data: JSON.stringify({ Vid: Vid, PurpId: PurId }),
        contentType: "application/json; charset=utf-8",
        success: function (data) {
            Success = true;
        },
        error: function (textStatus, errorThrown) {
            Success = false;
        }
    });
    //done after here
    return Success;
} 

You can only return the values from a synchronous function. Otherwise you will have to make a callback.

So I just added async:false, to your ajax call

Update:

jquery ajax calls are asynchronous by default. So success & error functions will be called when the ajax load is complete. But your return statement will be executed just after the ajax call is started.

A better approach will be:

     // callbackfn is the pointer to any function that needs to be called
     function ChangePurpose(Vid, PurId, callbackfn) {
        var Success = false;
        $.ajax({
            type: "POST",
            url: "CHService.asmx/SavePurpose",
            dataType: "text",
            data: JSON.stringify({ Vid: Vid, PurpId: PurId }),
            contentType: "application/json; charset=utf-8",
            success: function (data) {
                callbackfn(data)
            },
            error: function (textStatus, errorThrown) {
                callbackfn("Error getting the data")
            }
        });
     } 

     function Callback(data)
     {
        alert(data);
     }

and call the ajax as:

 // Callback is the callback-function that needs to be called when asynchronous call is complete
 ChangePurpose(Vid, PurId, Callback);

Your question is mixing a few different concepts. You started out saying you wanted to run sites on the same server using the same domain, but in different folders. That doesn't require any special setup. Once you get the single domain running, you just create folders under that docroot.

Based on the rest of your question, what you really want to do is run various sites on the same server with their own domain names.

The best documentation you'll find on the topic is the virtual host documentation in the apache manual.

There are two types of virtual hosts: name-based and IP-based. Name-based allows you to use a single IP address, while IP-based requires a different IP for each site. Based on your description above, you want to use name-based virtual hosts.

The initial error you were getting was due to the fact that you were using different ports than the NameVirtualHost line. If you really want to have sites served from ports other than 80, you'll need to have a NameVirtualHost entry for each port.

Assuming you're starting from scratch, this is much simpler than it may seem.

If you are using 2.3 or earlier, the first thing you need to do is tell Apache that you're going to use name-based virtual hosts.

NameVirtualHost *:80

If you are using 2.4 or later do not add a NameVirtualHost line. Version 2.4 of Apache deprecated the NameVirtualHost directive, and it will be removed in a future version.

Now your vhost definitions:

<VirtualHost *:80>
    DocumentRoot "/home/user/site1/"
    ServerName site1
</VirtualHost>

<VirtualHost *:80>
    DocumentRoot "/home/user/site2/"
    ServerName site2
</VirtualHost>

You can run as many sites as you want on the same port. The ServerName being different is enough to tell Apache which vhost to use. Also, the ServerName directive is always the domain/hostname and should never include a path.

If you decide to run sites on a port other than 80, you'll always have to include the port number in the URL when accessing the site. So instead of going to http://example.com you would have to go to http://example.com:81

If you have a UTF-8 string, where every byte is correct ('Ö' -> [195, 0] , [150, 0]), you can use the following:

public static string Utf8ToUtf16(string utf8String)
{
    /***************************************************************
     * Every .NET string will store text with the UTF-16 encoding, *
     * known as Encoding.Unicode. Other encodings may exist as     *
     * Byte-Array or incorrectly stored with the UTF-16 encoding.  *
     *                                                             *

     * UTF-8 inside UTF-16                                         *

     * First we need to get the UTF-8 Byte-Array and remove all    *
     * 0 byte (binary 0) while doing so.                           *
     *                                                             *
     * Binary 0 means end of string on UTF-8 encoding while on     *
     * UTF-16 one binary 0 does not end the string. Only if there  *

     *                                                             *

    // Get UTF-8 bytes and remove binary 0 bytes (filler)
    List<byte> utf8Bytes = new List<byte>(utf8String.Length);
    foreach (byte utf8Byte in utf8String)
    {
        // Remove binary 0 bytes (filler)
        if (utf8Byte > 0) {
            utf8Bytes.Add(utf8Byte);
        }
    }

    // Convert UTF-8 bytes to UTF-16 string
    return Encoding.UTF8.GetString(utf8Bytes.ToArray());
}

In my case the DLL result is a UTF-8 string too, but unfortunately the UTF-8 string is interpreted with UTF-16 encoding ('Ö' -> [195, 0], [19, 32]). So the ANSI '–' which is 150 was converted to the UTF-16 '–' which is 8211. If you have this case too, you can use the following instead:

public static string Utf8ToUtf16(string utf8String)
{
    // Get UTF-8 bytes by reading each byte with ANSI encoding
    byte[] utf8Bytes = Encoding.Default.GetBytes(utf8String);

    // Convert UTF-8 bytes to UTF-16 bytes
    byte[] utf16Bytes = Encoding.Convert(Encoding.UTF8, Encoding.Unicode, utf8Bytes);

    // Return UTF-16 bytes as UTF-16 string
    return Encoding.Unicode.GetString(utf16Bytes);
}

Or the Native-Method:

[DllImport("kernel32.dll")]
private static extern Int32 MultiByteToWideChar(UInt32 CodePage, UInt32 dwFlags, [MarshalAs(UnmanagedType.LPStr)] String lpMultiByteStr, Int32 cbMultiByte, [Out, MarshalAs(UnmanagedType.LPWStr)] StringBuilder lpWideCharStr, Int32 cchWideChar);

public static string Utf8ToUtf16(string utf8String)
{
    Int32 iNewDataLen = MultiByteToWideChar(Convert.ToUInt32(Encoding.UTF8.CodePage), 0, utf8String, -1, null, 0);
    if (iNewDataLen > 1)
    {
        StringBuilder utf16String = new StringBuilder(iNewDataLen);
        MultiByteToWideChar(Convert.ToUInt32(Encoding.UTF8.CodePage), 0, utf8String, -1, utf16String, utf16String.Capacity);

        return utf16String.ToString();
    }
    else
    {
        return String.Empty;
    }
}

If you need it the other way around, see Utf16ToUtf8. Hope I could be of help.

I solved by following these steps:

• Right click in the project > Configure > Convert to Maven project
• After the conversion, right click in the project > Maven > Update project

This fixes the "Deployment Assembly" settings of the project.

Depending on what browsers you're targeting, you could go for the object-fit property to solve this:

object-fit: cover;

or maybe fill is what you're looking for. Still under consideration for IE.

mp3 files sometimes throw strange mime types as per this answer: https://stackoverflow.com/a/2755288/14482130

If you are doing some user validation do not allow 'application/octet-stream' or 'application/x-zip-compressed' as suggested above since they can contain be .exe or other potentially dangerous files.

In order to validate when mime type gives a false negative you can use fleep as per this answer https://stackoverflow.com/a/52570299/14482130 to finish the validation.

I can confirm that mp4 just will not work in the video tag. No matter how much you try to mess with the type tag and the codec and the mime types from the server.

Crazy, because for the same exact video, on the same test page, the old embed tag for an mp4 works just fine in firefox. I spent all yesterday messing with this. Firefox is like IE all of a sudden, hours and hours of time, not billable. Yay.

Speaking of IE, it fails FAR MORE gracefully on this. When it can't match up the format it falls to the content between the tags, so it is possible to just put video around object around embed and everything works great. Firefox, nope, despite failing, it puts up the poster image (greyed out so that isn't even useful as a fallback) with an error message smack in the middle. So now the options are put in browser recognition code (meaning we've gained nothing on embedding videos in the last ten years) or ditch html5.

I have faced a similar problem, but it consoles the error like an encoding issue. After changing the IDE encoding, it works fine.

Spring uses an special logic for resolving this kind of circular dependencies with singleton beans. But this won't apply to other scopes. There is no elegant way of breaking this circular dependency, but a clumsy option could be this one:

@Component("bean1")
@Scope("view")
public class Bean1 {

    @Autowired
    private Bean2 bean2;

    @PostConstruct
    public void init() {
        bean2.setBean1(this);
    }
}

@Component("bean2")
@Scope("view")
public class Bean2 {

    private Bean1 bean1;

    public void setBean1(Bean1 bean1) {
        this.bean1 = bean1;
    }
}

Anyway, circular dependencies are usually a symptom of bad design. You would think again if there is some better way of defining your class dependencies.

It would seem that removing http:// from the url option ensures the the correct HTTP POST header is sent.

I dont think you need to fully qualify the name of the host, just use a relative URL as below.

   $.ajax({
      type: "POST",
      contentType: "application/json",
      url: '/Hello',
      data: { name: 'norm' },
      dataType: "json"
   });

An example of mine that works:

        $.ajax({
            type: "POST",
            url: siteRoot + "api/SpaceGame/AddPlayer",
            async: false,
            data: JSON.stringify({ Name: playersShip.name, Credits: playersShip.credits }),
            contentType: "application/json",
            complete: function (data) {
            console.log(data);
            wait = false;
        }
    });

Possibly related: jQuery $.ajax(), $.post sending "OPTIONS" as REQUEST_METHOD in Firefox

Edit: After some more research I found out the OPTIONS header is used to find out if the request from the originating domain is allowed. Using fiddler, I added the following to the response headers from my server.

 Access-Control-Allow-Origin: *
 Access-Control-Allow-Headers: Content-Type
 Access-Control-Allow-Methods: POST, GET, OPTIONS

Once the browser received this response it then sent off the correct POST request with json data. It would seem that the default form-urlencoded content type is considered safe and so does not undergo the extra cross domain checks.

It looks like you will need to add the previously mentioned headers to your servers response to the OPTIONS request. You should of course configure them to allow requests from specific domains rather then all.

I used the following jQuery to test this.

$.ajax({
   type: "POST",
   url: "http://myDomain.com/path/AddPlayer",
   data: JSON.stringify({
      Name: "Test",
       Credits: 0
   }),
   //contentType: "application/json",
   dataType: 'json',
   complete: function(data) {
       $("content").html(data);
  }
});?

That will be possible only if the HTML file is also loaded with the file protocol from the local user's harddisk.

If the HTML page is served by HTTP from a server, you can't access any local files by specifying them in a src attribute with the file:// protocol as that would mean you could access any file on the users computer without the user knowing which would be a huge security risk.

As Dimitar Bonev said, you can access a file if the user selects it using a file selector on their own. Without that step, it's forbidden by all browsers for good reasons. Thus, while his answer might prove useful for many people, it loosens the requirement from the code in the original question.

You can use from root directory:

RewriteEngine On
RewriteRule ^(?:system)\b.* /403.html

Or:

RewriteRule ^(?:system)\b.* /403.php # with header('HTTP/1.0 403 Forbidden');

Apache 2.4 virtual hosts hack

1.In http.conf specify the ports , below “Listen”

Listen 80
Listen 4000
Listen 7000
Listen 9000

2. In httpd-vhosts.conf

   <VirtualHost *:80>
   ServerAdmin [email protected]
   DocumentRoot "C:/Users/Vikas/Documents/NetBeansProjects/slider_website_hitesh/public_html"  
   ServerName hitesh_web.dev
   ErrorLog "logs/dummy-host2.example.com-error.log"
   CustomLog "logs/dummy-host2.example.com-access.log" common
   
   <Directory "C:/Users/Vikas/Documents/NetBeansProjects/slider_website_hitesh/public_html">
   Allow from all
   Require all granted
   </Directory>
   
   </VirtualHost>
   

   this is 2nd virtual host

   <VirtualHost *:80>
   ServerAdmin [email protected]
   DocumentRoot "E:/dabkick_git/DabKickWebsite"
   ServerName  www.my_mobile.dev
   ErrorLog "logs/dummy-host2.example.com-error.log"
   CustomLog "logs/dummy-host2.example.com-access.log" common
   
   <Directory "E:/dabkick_git/DabKickWebsite">
    Allow from all
    Require all granted
    </Directory>
   </VirtualHost>
   

3. In hosts.ics file of windows os “C:\Windows\System32\drivers\etc\host.ics”

   127.0.0.1             localhost
   127.0.0.1             hitesh_web.dev
   127.0.0.1             www.my_mobile.dev
   127.0.0.1             demo.multisite.dev
   

4.now type your “domain names” in the browser it will ping the particular folder specified in the documentRoot path

5.if you want to access those files in a particular port then replace 80 in httpd-vhosts.conf with port numbers like below and restart apache

   <VirtualHost *:4000>
ServerAdmin [email protected]
DocumentRoot "C:/Users/Vikas/Documents/NetBeansProjects/slider_website_hitesh/public_html"
ServerName hitesh_web.dev
ErrorLog "logs/dummy-host2.example.com-error.log"
CustomLog "logs/dummy-host2.example.com-access.log" common

<Directory "C:/Users/Vikas/Documents/NetBeansProjects/slider_website_hitesh/public_html">
Allow from all
Require all granted
</Directory>

</VirtualHost>

this is the 2nd vhost

<VirtualHost *:7000>
ServerAdmin [email protected]
DocumentRoot "E:/dabkick_git/DabKickWebsite"
ServerName  www.dabkick_mobile.dev
ErrorLog "logs/dummy-host2.example.com-error.log"
CustomLog "logs/dummy-host2.example.com-access.log" common

<Directory "E:/dabkick_git/DabKickWebsite">
Allow from all
Require all granted
</Directory>
</VirtualHost>

Note: for port number given virtual hosts you have to ping in browser like “http://hitesh_web.dev:4000/” or “http://www.dabkick_mobile.dev:7000/”

6.After doing all those changes you have to save the files and restart apache respectively.

Step 1 - The problem is with Eclipse IDE Step 2 - Right Click Maven Dependencies -> Build Path -> Remove Build Path

Update pom.xml for spring-web and spring-webmvc

Step 3 - Update Maven Dependencies

You will see the Spring-Web files will be in the maven dependencies folder.

The error usually gets introduced while creation of CSV. Try using Linux for saving the CSV as a TextCSV. Libre Office in Ubuntu can enforce the encoding to be UTF-8, worked for me. I wasted a lot of time trying this on Mac OS. Linux is the key. I've tested on Ubuntu.

Good Luck

I found that when I had this issue that I had to delete the application.config file from my solution. I was pulling the code from co-worker's repository whose config file was mapping to their local computer resources (and not my own). In addition to that, I had to create a new virtual directory as explained in the previous answers.

you need to add jar file in your build path..

commons-dbcp-1.1-RC2.jar

or any version of that..!!!!

ADDED : also make sure you have commons-pool-1.1.jar too in your build path.

ADDED: sorry saw complete list of jar late... may be version clashes might be there.. better check out..!!! just an assumption.

You mentioned using json2.js to stringify your data, but the POSTed data appears to be URLEncoded JSON You may have already seen it, but this post about the invalid JSON primitive covers why the JSON is being URLEncoded.

I'd advise against passing a raw, manually-serialized JSON string into your method. ASP.NET is going to automatically JSON deserialize the request's POST data, so if you're manually serializing and sending a JSON string to ASP.NET, you'll actually end up having to JSON serialize your JSON serialized string.

I'd suggest something more along these lines:

var markers = [{ "position": "128.3657142857143", "markerPosition": "7" },
               { "position": "235.1944023323615", "markerPosition": "19" },
               { "position": "42.5978231292517", "markerPosition": "-3" }];

$.ajax({
    type: "POST",
    url: "/webservices/PodcastService.asmx/CreateMarkers",
    // The key needs to match your method's input parameter (case-sensitive).
    data: JSON.stringify({ Markers: markers }),
    contentType: "application/json; charset=utf-8",
    dataType: "json",
    success: function(data){alert(data);},
    error: function(errMsg) {
        alert(errMsg);
    }
});

The key to avoiding the invalid JSON primitive issue is to pass jQuery a JSON string for the data parameter, not a JavaScript object, so that jQuery doesn't attempt to URLEncode your data.

On the server-side, match your method's input parameters to the shape of the data you're passing in:

public class Marker
{
  public decimal position { get; set; }
  public int markerPosition { get; set; }
}

[WebMethod]
public string CreateMarkers(List<Marker> Markers)
{
  return "Received " + Markers.Count + " markers.";
}

You can also accept an array, like Marker[] Markers, if you prefer. The deserializer that ASMX ScriptServices uses (JavaScriptSerializer) is pretty flexible, and will do what it can to convert your input data into the server-side type you specify.

Ohh what a mess! My advise: When its comes to messy poms or project packaging, Eclipse is really bad at showing the real problem. It will tell you some dependencies are missing, when in fact for pom is malformed or some other problem are present in your pom.

Leave Eclipse alone are run a maven install. You will get to the real problem really quick!

This will happen if the host page is HTTPS and the included javascript source path is HTTP. The two protocols must be the same, HTTPS. The tell tail sign would be to check under Firebug and notice that the JS is "denied access".

I like this one depending of purpose

window.location.href.split("/")[2] == "localhost:17000" //always domain + port

You can apply it on any url-string

var url = "http://localhost:17000/sub1/sub2/mypage.html?q=12";
url.split("/")[2] == "localhost:17000"
url.split("/")[url.split("/").length-1] == "mypage.html?q=12"

Removing protocol, domain & path from url-string (relative path)

var arr = url.split("/");
if (arr.length>3)
   "/" + arr.splice(3, arr.length).join("/") == "/sub1/sub2/mypage.html?q=12"

adjust video start and end time when using the video tag in html5;

http://www.yoursite.com/yourfolder/yourfile.mp4#t=5,15

where left of comma is start time in seconds, right of comma is end time in seconds. drop the comma and end time to effect the start time only.

I found my own mistake, I did not add log file name: ErrorLog /var/log/apache2
And this path: Directory "/usr/share/doc/" Did not contain website sources.

After I changed these two, all worked. Interestingly, apache did not issue any errors, just did not open my website silently on my Mac OS Sierra.

I solved it simply by removing the domain from the request url.

Before: https://some.domain.com/_vti_bin/service.svc

After: /_vti_bin/service.svc

Here is a well tested function which i used for my projects with detailed self explanatory comments

There are many times when the ports other than 80 are blocked by server firewall so the code appears to be working fine on localhost but not on the server

function get_page($url){

global $proxy;
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, $url);
//curl_setopt($ch, CURLOPT_PROXY, $proxy);
curl_setopt($ch, CURLOPT_HEADER, 0); // return headers 0 no 1 yes
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true); // return page 1:yes
curl_setopt($ch, CURLOPT_TIMEOUT, 200); // http request timeout 20 seconds
curl_setopt($ch, CURLOPT_FOLLOWLOCATION, true); // Follow redirects, need this if the url changes
curl_setopt($ch, CURLOPT_MAXREDIRS, 2); //if http server gives redirection responce
curl_setopt($ch, CURLOPT_USERAGENT,
    "Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.8.1.7) Gecko/20070914 Firefox/2.0.0.7");
curl_setopt($ch, CURLOPT_COOKIEJAR, "cookies.txt"); // cookies storage / here the changes have been made
curl_setopt($ch, CURLOPT_COOKIEFILE, "cookies.txt");
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false); // false for https
curl_setopt($ch, CURLOPT_ENCODING, "gzip"); // the page encoding

$data = curl_exec($ch); // execute the http request
curl_close($ch); // close the connection
return $data;
}

mvn clean install -U

Solved my problem. Since the repos were cached, I needed to force it to get latest version.

If you are running your application just on localhost and it is not yet live, I believe it is very difficult to send mail using this.

Once you put your application online, I believe that this problem should be automatically solved. By the way,ini_set() helps you to change the values in php.ini during run time.

This is the same question as Failed to connect to mailserver at "localhost" port 25

also check this php mail function not working

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

The simplest way and will help you with is set CharSet to UTF-8

$mail->CharSet = "UTF-8"

As noted by jitter, the $.ajax function serializes any object/array used as the data parameter into a url-encoded format. Oddly enough, the dataType parameter only applies to the response from the server - and not to any data in the request.

After encountering the same problem I downloaded and used the jquery-json plugin to correctly encode the request data to the ScriptService. Then, used the $.toJSON function to encode the desired arguments to send to the server:

$.ajax({
    type: "POST",
    url: "EditUserProfile.aspx/DeleteRecord",
    data: $.toJSON(obj),
    contentType: "application/json; charset=utf-8",
    dataType: "json"
    ....
});

To keep your options open, if you're using .NET 3.5 or later, here is a wrapped up example you can use straight from the framework using Generics. As others have mentioned, if it's not just simple objects you should really use JSON.net.

public static string Serialize<T>(T obj)
{
    DataContractJsonSerializer serializer = new DataContractJsonSerializer(obj.GetType());
    MemoryStream ms = new MemoryStream();
    serializer.WriteObject(ms, obj);
    string retVal = Encoding.UTF8.GetString(ms.ToArray());
    return retVal;
}

public static T Deserialize<T>(string json)
{
    T obj = Activator.CreateInstance<T>();
    MemoryStream ms = new MemoryStream(Encoding.Unicode.GetBytes(json));
    DataContractJsonSerializer serializer = new DataContractJsonSerializer(obj.GetType());
    obj = (T)serializer.ReadObject(ms);
    ms.Close();
    return obj;
}

You'll need:

using System.Runtime.Serialization;

using System.Runtime.Serialization.Json;

Try the below code

HttpRequest req = System.Web.HttpContext.Current.Request
string browserName = req.Browser.Browser;

Change the return type of your GetResults to be List<Person>.
Eliminate the code that you use to serialize the List to a json string - WCF does this for you automatically.

Using your definition for the Person class, this code works for me:

public List<Person> GetPlayers()
{
    List<Person> players = new List<Person>();
    players.Add(new  Person { FirstName="Peyton", LastName="Manning", Age=35 } );
    players.Add(new  Person { FirstName="Drew", LastName="Brees", Age=31 } );
    players.Add(new  Person { FirstName="Brett", LastName="Favre", Age=58 } );

    return players;
}

results:

[{"Age":35,"FirstName":"Peyton","LastName":"Manning"},  
 {"Age":31,"FirstName":"Drew","LastName":"Brees"},  
 {"Age":58,"FirstName":"Brett","LastName":"Favre"}]

(All on one line)

I also used this attribute on the method:

[WebInvoke(Method = "GET",
           RequestFormat = WebMessageFormat.Json,
           ResponseFormat = WebMessageFormat.Json,
           UriTemplate = "players")]

WebInvoke with Method= "GET" is the same as WebGet, but since some of my methods are POST, I use all WebInvoke for consistency.

The UriTemplate sets the URL at which the method is available. So I can do a GET on http://myserver/myvdir/JsonService.svc/players and it just works.

Also check out IIRF or another URL rewriter to get rid of the .svc in the URI.

from this page:

I found this info:

The mod_fastcgi process manager isn't particularly patient though (there's room for improvement here) and since it has to shutdown too, sends a SIGTERM to all of the FastCGI applications it is responsible for. Apache will restart the process manager and it will restart its managed applications (as if the server was just started). SIGTERM is, well, SIGTERM - your application should exit quickly.

What this implies to me is that if Database I/O, or some other part of the CGI script, fails to respond in a timely fashion (ie getting slower with data-volume growth), that mod_fastcgi is killing the script......is that how other people interpret these docs or what am I missing..

In your client SOAP handler you need to set javax.xml.ws.security.auth.username and javax.xml.ws.security.auth.password property as follow:

public class ClientHandler implements SOAPHandler<SOAPMessageContext>{

    public boolean handleMessage(final SOAPMessageContext soapMessageContext)
    {
        final Boolean outInd = (Boolean)soapMessageContext.get(MessageContext.MESSAGE_OUTBOUND_PROPERTY);
        if (outInd.booleanValue())
        {
          try 
          {
               soapMessageContext.put("javax.xml.ws.security.auth.username", <ClientUserName>);
               soapMessageContext.put("javax.xml.ws.security.auth.password", <ClientPassword>);
          } 
          catch (Exception e)
          {
               e.printStackTrace();
               return false;
          }
         }
      return true;
     }
}

I've created a tool called Rector, that handles instant upgrades. There is also mysql ? mysqli set.

It handles:

• function renaming

• constant renaming

• switched arguments

• non-1:1 function calls changes, e.g.

    $data = mysql_db_name($result, $row);
  

  ?

    mysqli_data_seek($result, $row);
    $fetch = mysql_fetch_row($result);
    $data = $fetch[0];
  

How to use Rector?

1. Install it via Composer

composer require rector/rector --dev

// or in case of composer conflicts
composer require rector/rector-prefixed --dev

2. Create rector.php in project root directory with the Mysql to Mysqli set

<?php

use Rector\Core\Configuration\Option;
use Rector\Set\ValueObject\SetList;
use Symfony\Component\DependencyInjection\Loader\Configurator\ContainerConfigurator;

return static function (ContainerConfigurator $containerConfigurator): void {

    $parameters->set(Option::SETS, [
        SetList::MYSQL_TO_MYSQLI,
    ]);
};

3. Let Rector run on e.g. /src directory to only show the diffs

vendor/bin/rector process src --dry-run

4. Let Rector change the code

vendor/bin/rector process src

I've already run it on 2 big PHP projects and it works perfectly.

I found out that my web reference was out of date and the code was calling a removed web service.

To receive a pure JSON string, without it being wrapped into an XML, you have to write the JSON string directly to the HttpResponse and change the WebMethod return type to void.

    [System.Web.Script.Services.ScriptService]
    public class WebServiceClass : System.Web.Services.WebService {
        [WebMethod]
        public void WebMethodName()
        {
            HttpContext.Current.Response.Write("{property: value}");
        }
    }

Just to add some specific settings, I had a similar setup (with Apache 2.0.63 reverse proxying onto Tomcat 5.0.27).

For certain URLs the Tomcat server could take perhaps 20 minutes to return a page.

I ended up modifying the following settings in the Apache configuration file to prevent it from timing out with its proxy operation (with a large over-spill factor in case Tomcat took longer to return a page):

Timeout 5400
ProxyTimeout 5400

Some backgound

ProxyTimeout alone wasn't enough. Looking at the documentation for Timeout I'm guessing (I'm not sure) that this is because while Apache is waiting for a response from Tomcat, there is no traffic flowing between Apache and the Browser (or whatever http client) - and so Apache closes down the connection to the browser.

I found that if I left the Timeout setting at its default (300 seconds), then if the proxied request to Tomcat took longer than 300 seconds to get a response the browser would display a "502 Proxy Error" page. I believe this message is generated by Apache, in the knowledge that it's acting as a reverse proxy, before it closes down the connection to the browser (this is my current understanding - it may be flawed).

The proxy error page says:

Proxy Error

The proxy server received an invalid response from an upstream server. The proxy server could not handle the request GET.

Reason: Error reading from remote server

...which suggests that it's the ProxyTimeout setting that's too short, while investigation shows that Apache's Timeout setting (timeout between Apache and the client) that also influences this.

A proven solution for Visual Studio extension for Data Tools for Business Intelligence (SSDT-BI 2013):

1. Move the Project folder to its new location (don't rename anything yet)
2. In Solution Explorer, rename the Project / Solution.
3. Close (and save) the newly-renamed project.
4. Rename the project's folder and .sln file.
5. Use a text editor and open the newly-renamed project solution file (.sln) (I used Notepad++)
6. In line number 6 you'll see: "Project {fdjfksdjk4387!...} = "OLDPROJECT", "OLDFOLDER\OLDPROJECT.rptproj". Rename everything with the new names used in step 4. (i.e. ... = "NEWPROJECT", "NEWFOLDER\NEWPROJECT.rptproj"... )
7. That's it!

It was tested 100% and worked flawlessly in my case.

NOTE: I can't confirm if it works under different project templates and other Visual Studio versions. As always, do backup everything beforehand.

If you want to set something on a timer, you can use JavaScript's setTimeout or setInterval methods:

setTimeout ( expression, timeout );
setInterval ( expression, interval );

Where expression is a function and timeout and interval are integers in milliseconds. setTimeout runs the timer once and runs the expression once whereas setInterval will run the expression every time the interval passes.

So in your case it would work something like this:

setInterval(function() {
    //call $.ajax here
}, 5000); //5 seconds

As far as the Ajax goes, see jQuery's ajax() method. If you run an interval, there is nothing stopping you from calling the same ajax() from other places in your code.

If what you want is for an interval to run every 30 seconds until a user initiates a form submission...and then create a new interval after that, that is also possible:

setInterval() returns an integer which is the ID of the interval.

var id = setInterval(function() {
    //call $.ajax here
}, 30000); // 30 seconds

If you store that ID in a variable, you can then call clearInterval(id) which will stop the progression.

Then you can reinstantiate the setInterval() call after you've completed your ajax form submission.

The answer that the OP accepted is wildly different from the question I thought was asked. I thought the OP wanted a way to auto-align = signs or + signs, similar to the tabularize plugin for vim.

For this task, I found the Columns4Eclipse plugin to be just what I needed.

In SQL Query, you can write this code:

select table_name from information_schema.tables where table_schema='YOUR_TABLE_SCHEME';

Replace your table scheme with YOUR_TABLE_SCHEME;

Example:

select table_name from information_schema.tables where table_schema='eLearningProject';

To see all scheme and all tables, there is no need of where clause:

select table_name from information_schema.tables

Try this code:

<input type="text" name="Phone Number" pattern="[7-9]{1}[0-9]{9}" 
       title="Phone number with 7-9 and remaing 9 digit with 0-9">

This code will inputs only in the following format:

9238726384 (starting with 9 or 8 or 7 and other 9 digit using any number)
8237373746
7383673874

Incorrect format:
2937389471(starting not with 9 or 8 or 7)
32796432796(more than 10 digit)
921543(less than 10 digit)

You can select dropdown option value by name

jQuery("#option_id").find("option:contains('Monday')").each(function()
{
 if( jQuery(this).text() == 'Monday' )
 {
  jQuery(this).attr("selected","selected");
  }
});

I have scaled down the image in this way:

ImageView iv  = (ImageView)waypointListView.findViewById(R.id.waypoint_picker_photo);
Bitmap d = new BitmapDrawable(ctx.getResources() , w.photo.getAbsolutePath()).getBitmap();
int nh = (int) ( d.getHeight() * (512.0 / d.getWidth()) );
Bitmap scaled = Bitmap.createScaledBitmap(d, 512, nh, true);
iv.setImageBitmap(scaled);

Assuming there are no prepending/succeeding whitespace characters, there are still a few ways to assert string equality. Some of those are:

• strings.ToLower(..) then ==
• strings.EqualFold(.., ..)
• cases#Lower paired with ==
• cases#Fold paired with ==

Here are some basic benchmark results (in these tests, strings.EqualFold(.., ..) seems like the most performant choice):

What will be cleaner and easier to maintain?

All things being equal, probably JavaFX - the API is much more consistent across components. However, this depends much more on how the code is written rather than what library is used to write it.

And what will be faster to build from scratch?

Highly dependent on what you're building. Swing has more components around for it (3rd party as well as built in) and not all of them have made their way to the newer JavaFX platform yet, so there may be a certain amount of re-inventing the wheel if you need something a bit custom. On the other hand, if you want to do transitions / animations / video stuff then this is orders of magnitude easier in FX.

One other thing to bear in mind is (perhaps) look and feel. If you absolutely must have the default system look and feel, then JavaFX (at present) can't provide this. Not a big must have for me (I prefer the default FX look anyway) but I'm aware some policies mandate a restriction to system styles.

Personally, I see JavaFX as the "up and coming" UI library that's not quite there yet (but more than usable), and Swing as the borderline-legacy UI library that's fully featured and supported for the moment, but probably won't be so much in the years to come (and therefore chances are FX will overtake it at some point.)

If you are looking to create an instant messenger for Android, this code should get you started somewhere.

Excerpt from the source :

This is a simple IM application runs on Android, application makes http request to a server, implemented in php and mysql, to authenticate, to register and to get the other friends' status and data, then it communicates with other applications in other devices by socket interface.

EDIT : Just found this! Maybe it's not related to WhatsApp. But you can use the source to understand how chat applications are programmed.

There is a website called Scringo. These awesome people provide their own SDK which you can integrate in your existing application to exploit cool features like radaring, chatting, feedback, etc. So if you are looking to integrate chat in application, you could just use their SDK. And did I say the best part? It's free!

*UPDATE : * Scringo services will be closed down on 15 February, 2015.

Crash page?

(It happens when MySQL has to query large rows. By default, memory_limit is set to small, which was safer for the hardware.)

You can check your system existing memory status, before increasing php.ini:

# free -m
             total       used       free     shared    buffers     cached
Mem:         64457      63791        666          0       1118      18273
-/+ buffers/cache:      44398      20058
Swap:         1021          0       1021

Here I have increased it as in the following and then do service httpd restart to fix the crash page issue.

# grep memory_limit /etc/php.ini
memory_limit = 512M

The correct answer is already given, nevertheless here is the better way (than switch):

private Dictionary<Operator, Func<int, int, double>> operators =
    new Dictionary<Operator, Func<int, int, double>>
    {
        { Operator.PLUS, ( a, b ) => a + b },
        { Operator.MINUS, ( a, b ) => a - b },
        { Operator.MULTIPLY, ( a, b ) => a * b },
        { Operator.DIVIDE ( a, b ) => (double)a / b },
    };

public double Calculate( int left, int right, Operator op )
{
    return operators.ContainsKey( op ) ? operators[ op ]( left, right ) : 0.0;
}

Put this in your .vimrc configuration file.

First thing that pop-up in google results http://think2loud.com/224-reading-xml-with-jquery/ There's no simple way to access xml structure (like you described Pages->pagename->controls->test) in jQuery without any plugins.

Use mathematics first find square root of number then start loop till the number ends which you get after square rooting. check for each value whether the given number is divisible by the iterating value .if any value divides the given number then it is not a prime number otherwise prime. Here is the code

 bool is_Prime(int n)
 {

   int square_root = sqrt(n); // use math.h
   int toggle = 1;
   for(int i = 2; i <= square_root; i++)
   {
     if(n%i==0)
     { 
        toggle = 0;
        break;
     }
   }

   if(toggle)
     return true;
   else
     return false;

In the media query of specific devices, please use '!important' keyword to override the default CSS. Otherwise that does not change your webpage view on that particular devices.

You can add a UIImageView that is, for example, 1 point high and as wide as the cell's frame, and then set its origin to the bottom left corner of the cell.

var o = ...
var proto =  Object.getPrototypeOf(o);
proto === SomeThing;

Keep a handle on the prototype you expect the object to have, then compare against it.

for example

var o = "someString";
var proto =  Object.getPrototypeOf(o);
proto === String.prototype; // true

Best way is to add !important suffix to the selector .

Example:

 #selector{
     display: inline-block !important;                   
}

This will disable/enable the options when you select/remove them, respectively.

$("#theSelect").change(function(){          
    var value = $(this).val();
    if (value === '') return;
    var theDiv = $(".is" + value);

    var option = $("option[value='" + value + "']", this);
    option.attr("disabled","disabled");

    theDiv.slideDown().removeClass("hidden");
    theDiv.find('a').data("option",option);
});


$("div a.remove").click(function () {     
    $(this).parent().slideUp(function() { $(this).addClass("hidden"); });
    $(this).data("option").removeAttr('disabled');
});

After "AND" and after "OR" the QUERY has forgotten what it is all about.

I would also not know that it is about in any SQL / programming language.

if(SOMETHING equals "X" or SOMETHING equals "Y")

COLUMN NOT LIKE "A%" AND COLUMN NOT LIKE "B%"

you can save them into a $_SESSION variable and then when the user calls that page again populate all the inputs with their respective session variables.

Sounds like you have a utility class similar to java.lang.Math.
The approach there is final class with private constructor and static methods.

But beware of what this does for testability, I recommend reading this article
Static Methods are Death to Testability

Since this question was originally asked, John Resig (the primary author of jQuery) has forked and improved the js-hotkeys project. His version is available at:

http://github.com/jeresig/jquery.hotkeys

You can safely delete the WSDL cache files. If you wish to prevent future caching, use:

ini_set("soap.wsdl_cache_enabled", 0);

or dynamically:

$client = new SoapClient('http://somewhere.com/?wsdl', array('cache_wsdl' => WSDL_CACHE_NONE) );

I've just fixed this for my machine. Maybe it will work for some. Maybe not for others, but here is what worked for me.

In IIS, I had to add bindings for https to the default website (or, I suppose, the website you are running the app under).

Now my localhost works when debugging from Visual Studio.

How about

$([your selector]).attr('colspan',3);

I would imagine that to work but have no way to test at the moment. Using .attr() would be the usual jQuery way of setting attributes of elements in the wrapped set.

As has been mentioned in another answer, in order to get this to work would require removing the td elements that have no text in them from the DOM. It may be easier to do this all server side

EDIT:

As was mentioned in the comments, there is a bug in attempting to set colspan using attr() in IE, but the following works in IE6 and FireFox 3.0.13.

Working Demo

notice the use of the attribute colSpan and not colspan - the former works in both IE and Firefox, but the latter does not work in IE. Looking at jQuery 1.3.2 source, it would appear that attr() attempts to set the attribute as a property of the element if

1. it exists as a property on the element (colSpan exists as a property and defaults to 1 on <td> HTMLElements in IE and FireFox)
2. the document is not xml and
3. the attribute is none of href, src or style

using colSpan as opposed to colspan works with attr() because the former is a property defined on the element whereas the latter is not.

the fall-through for attr() is to attempt to use setAttribute() on the element in question, setting the value to a string, but this causes problems in IE (bug #1070 in jQuery)

// convert the value to a string (all browsers do this but IE) see #1070
elem.setAttribute( name, "" + value ); 

In the demo, for each row, the text in each cell is evaluated. If the text is a blank string, then the cell is removed and a counter incremented. The first cell in the row that does not have class="colTime" has a colspan attribute set to the value of the counter + 1 (for the span it occupies itself).

After this, for each row, the text in the cell with class="colspans" is set to the colspan attribute values of each cell in the row from left to right.

jQuery code

$(function() {

  $('table.tblSimpleAgenda tr').each(function() {
    var tr = this;
    var counter = 0;

    $('td', tr).each(function(index, value) {
      var td = $(this);

      if (td.text() == "") {
        counter++;
        td.remove();
      }
    });

    if (counter !== 0) {
      $('td:not(.colTime):first', tr)
        .attr('colSpan', '' + parseInt(counter + 1,10) + '');
    }
  });

  $('td.colspans').each(function(){
    var td = $(this);
    var colspans = [];

    td.siblings().each(function() {
      colspans.push(($(this).attr('colSpan')) == null ? 1 : $(this).attr('colSpan'));
    });

    td.text(colspans.join(','));
  });

});

This is just a demonstration to show that attr() can be used, but to be aware of it's implementation and the cross-browser quirks that come with it. I've also made some assumptions about your table layout in the demo (i.e. apply the colspan to the first "non-Time" cell in each row), but hopefully you get the idea.

public static Stream ToStream(this Image image)
{
     var stream = new MemoryStream();

     image.Save(stream, image.RawFormat);
     stream.Position = 0;

     return stream;
 }

Have you tried using the DataTable.Select(filterExpression, sortExpression) method?

BinaryReader b = new BinaryReader(file.InputStream);
byte[] binData = b.ReadBytes(file.InputStream.Length);

line 2 should be replaced with

byte[] binData = b.ReadBytes(file.ContentLength);

You can go like this: error.response.data
In my case, I got error property from backend. So, I used error.response.data.error

My code:

axios
  .get(`${API_BASE_URL}/students`)
  .then(response => {
     return response.data
  })
  .then(data => {
     console.log(data)
  })
  .catch(error => {
     console.log(error.response.data.error)
  })

The answers are working fine with xls format but, in my case, it didn't work for xlsx format. Thus I added some code here. it works both xls and xlsx format.

I took the sample from the official sample link.

Hope it may help !

function fileReader(oEvent) {
        var oFile = oEvent.target.files[0];
        var sFilename = oFile.name;

        var reader = new FileReader();
        var result = {};

        reader.onload = function (e) {
            var data = e.target.result;
            data = new Uint8Array(data);
            var workbook = XLSX.read(data, {type: 'array'});
            console.log(workbook);
            var result = {};
            workbook.SheetNames.forEach(function (sheetName) {
                var roa = XLSX.utils.sheet_to_json(workbook.Sheets[sheetName], {header: 1});
                if (roa.length) result[sheetName] = roa;
            });
            // see the result, caution: it works after reader event is done.
            console.log(result);
        };
        reader.readAsArrayBuffer(oFile);
}

// Add your id of "File Input" 
$('#fileUpload').change(function(ev) {
        // Do something 
        fileReader(ev);
}

This can also be achieved by specifying stale file name for schemas and not clearing output directory. The default out put directory is automatically included in classpath which is little convenient. If we specify different output directory one has to take care of classpath to use this code in IDE. For example -

use "%zo" for off_t. (octal) or "%zu" for decimal.

Its already explained, Will try to give an example

let the select list be

select_list = { eligible: 1, ineligible: 0 }

So the following code results in

<%= f.select :to_vote, select_list %>

<select name="to_vote" id="to_vote">
  <option value="1">eligible</option>
  <option value="0">ineligible</option>
</select>

So to make a option selected by default we have to use selected: value.

<%= f.select :to_vote, select_list, selected: select_list.can_vote? ? 1 : 0 %>

if can_vote? returns true it sets selected: 1 then the first value will be selected else second.

select name="driver[bca_aw_eligible]" id="driver_bca_aw_eligible">
  <option value="1">eligible</option>
  <option selected="selected" value="0">ineligible</option>
</select>

if the select options are just a array list instead of hast then the selected will be just the value to be selected for example if

select_list = [ 'eligible', 'ineligible' ]

now the selected will just take

<%= f.select :to_vote, select_list, selected: 'ineligible' %>

You need to understand that a Git repository is not just a tree of directories and files, but also stores a history of those trees - which might contain branches and merges.

When fetching from a repository, you will copy all or some of the branches there to your repository. These are then in your repository as "remote tracking branches", e.g. branches named like remotes/origin/master or such.

Fetching new commits from the remote repository will not change anything about your local working copy.

Your working copy has normally a commit checked out, called HEAD. This commit is usually the tip of one of your local branches.

I think you want to update your local branch (or maybe all the local branches?) to the corresponding remote branch, and then check out the latest branch.

To avoid any conflicts with your working copy (which might have local changes), you first clean everything which is not versioned (using git clean). Then you check out the local branch corresponding to the remote branch you want to update to, and use git reset to switch it to the fetched remote branch. (git pull will incorporate all updates of the remote branch in your local one, which might do the same, or create a merge commit if you have local commits.)

(But then you will really lose any local changes - both in working copy and local commits. Make sure that you really want this - otherwise better use a new branch, this saves your local commits. And use git stash to save changes which are not yet committed.)

Edit: If you have only one local branch and are tracking one remote branch, all you need to do is

git pull

from inside the working directory.

This will fetch the current version of all tracked remote branches and update the current branch (and the working directory) to the current version of the remote branch it is tracking.

if wants to convert UTC date to milliseconds
syntax : Date.UTC(year, month, ?day, ?hours, ?min, ?sec, ?milisec);
e.g :
date_in_mili = Date.UTC(2020, 07, 03, 03, 40, 40, 40);
console.log('miliseconds', date_in_mili);

The first part (setting the output size explictly) isn't too hard:

import matplotlib.pyplot as plt
list1 = [3,4,5,6,9,12]
list2 = [8,12,14,15,17,20]
fig = plt.figure(figsize=(4,3))
ax = fig.add_subplot(111)
ax.plot(list1, list2)
fig.savefig('fig1.png', dpi = 300)
fig.close()

But after a quick google search on matplotlib + tiff, I'm not convinced that matplotlib can make tiff plots. There is some mention of the GDK backend being able to do it.

One option would be to convert the output with a tool like imagemagick's convert.

(Another option is to wait around here until a real matplotlib expert shows up and proves me wrong ;-)

You just need to manually set the desired permissions with chmod():

private function writeFileContent($file, $content){
    $fp = fopen($file, 'w');
    fwrite($fp, $content);
    fclose($fp);

    // Set perms with chmod()
    chmod($file, 0777);
    return true;
}

One way is to use the multiple class selector (no space as that is the descendant selector):

.reMode_hover:not(.reMode_selected):hover _x000D_
{_x000D_
   background-color: #f0ac00;_x000D_
}

<a href="" title="Design" class="reMode_design  reMode_hover">_x000D_
    <span>Design</span>_x000D_
</a>_x000D_
_x000D_
<a href="" title="Design" _x000D_
 class="reMode_design  reMode_hover reMode_selected">_x000D_
    <span>Design</span>_x000D_
</a>

Try this:

  $('.select').on('select2:selecting select2:unselecting', function(e) {

      var value = e.params.args.data.id;

  });

You need to change your code as below:-

<html>
<body>

<span id="span_Id">Click the button to display the content.</span>

<button onclick="displayDate()">Click Me</button>

<script>
function displayDate() {
   var span_Text = document.getElementById("span_Id").innerText;
   alert (span_Text);
}
</script>
</body>
</html>

After doing this you will get the tag value in alert.

For AWK haters, and for simplicity, this contraption works for me:

help:
  make -qpRr $(lastword $(MAKEFILE_LIST)) | egrep -v '(^(\.|:|#|\s|$)|=)' | cut -d: -f1

(for use outside a Makefile, just remove $(lastword ...) or replace it with the Makefile path).

This solution will not work if you have "interesting" rule names but will work well for most simple setups. The main downside of a make -qp based solution is (as in other answers here) that if the Makefile defines variable values using functions - they will still be executed regardless of -q, and if using $(shell ...) then the shell command will still be called and its side effects will happen. In my setup often the side effects of running shell functions is unwanted output to standard error, so I add 2>/dev/null after the make command.

FOR the best performance, use specific column name instead of * - for example:

SELECT TOP 1 <columnName> 
FROM <tableName> 

This is optimal because, instead of returning the whole list of columns, it is returning just one. That can save some time.

Also, returning just first row if there are any values, makes it even faster. Actually you got just one value as the result - if there are any rows, or no value if there is no rows.

If you use the table in distributed manner, which is most probably the case, than transporting just one value from the server to the client is much faster.

You also should choose wisely among all the columns to get data from a column which can take as less resource as possible.

Whenever this happens to me, I press Ctrl+Shift+R which refreshes intellisense, close the query window (save if necessary), then start a new session which usually works quite well.

It depends if you consider if a subclass of a given class is equals to its parent.

class LastName
{
(...)
}


class FamilyName
extends LastName
{
(..)
}

here I would use 'instanceof', because I want a LastName to be compared to FamilyName

class Organism
{
}

class Gorilla extends Organism
{
}

here I would use 'getClass', because the class already says that the two instances are not equivalent.

Took a while to figure this one out. Seems most of us missed the obvious error…the last “-” is not escaped.

Adding the . and | as I’ve seen other suggest may work for you, but the regex was supposed to be:

if ( ! preg_match("/^[a-z0-9:_\/\-\.|]+$/i", $str))  

Check to make sure that the file is complete. This error message can occur if you only partially downloaded a file or if it has major issues. Check the MD5sum.

This worked for me on multiple flavors of Linux, where some of these other solutions did not (including the most popular ones here). I think it's more readable too...

echo Press enter to continue; read dummy;

Note that a variable needs to be supplied as an argument to read.

I was using Write #1 "Print my Line" instead I tried Print #1, "Print my Line" and it give me all the data without default Quote(")

Dim strFile_Path As String
strFile_Path = ThisWorkbook.Path & "\" & "XXXX" & VBA.Format(VBA.Now, "dd-MMM-yyyy hh-mm") & ".txt"
Open strFile_Path For Output As #1

Dim selectedFeature As String

For counter = 7 To maxNumberOfColumn

        selectedFeature = "X"
        Print #1, selectedFeature
        'Write #1, selectedFeature

Next counter
Close #1

I am assuming that you need the JDK itself. If so you can accomplish this with:

sudo add-apt-repository ppa:sun-java-community-team/sun-java6

sudo apt-get update

sudo apt-get install sun-java6-jdk

You don't really need to go around editing sources or anything along those lines.

Honestly though, whether there is a way for it to evaluate to true or not (and as others have shown, there are multiple ways), the answer I'd be looking for, speaking as someone who has conducted hundreds of interviews, would be something along the lines of:

"Well, maybe yes under some weird set of circumstances that aren't immediately obvious to me... but if I encountered this in real code then I would use common debugging techniques to figure out how and why it was doing what it was doing and then immediately refactor the code to avoid that situation... but more importantly: I would absolutely NEVER write that code in the first place because that is the very definition of convoluted code, and I strive to never write convoluted code".

I guess some interviewers would take offense to having what is obviously meant to be a very tricky question called out, but I don't mind developers who have an opinion, especially when they can back it up with reasoned thought and can dovetail my question into a meaningful statement about themselves.

Short and simple differences between Tcp and Udp protocol:

1) Tcp - Transmission control protocol and Udp - User datagram protocol.

2) Tcp is reliable protocol, Where as Udp is a unreliable protocol.

3) Tcp is a stream oriented, where as Udp is a message oriented protocol.

4) Tcp is a slower than Udp.

Try this for getting form input text value to JavaScript object...

var fieldPair = {};
$("#form :input").each(function() {
    if($(this).attr("name").length > 0) {
        fieldPair[$(this).attr("name")] = $(this).val();
    }
});

console.log(fieldPair);

The package is not fully compatible with dotnetcore 2.0 for now.

eg, for 'Microsoft.AspNet.WebApi.Client' it maybe supported in version (5.2.4). See Consume new Microsoft.AspNet.WebApi.Client.5.2.4 package for details.

You could try the standard Client package as Federico mentioned.

If that still not work, then as a workaround you can only create a Console App (.Net Framework) instead of the .net core 2.0 console app.

Reference this thread: Microsoft.AspNet.WebApi.Client supported in .NET Core or not?

You can achieve your desired through easily by CSS :-

HTML

<input type="submit" name="submit" value="Submit Application" id="submit" />

CSS

#submit {
    background-color: #ccc;
    -moz-border-radius: 5px;
    -webkit-border-radius: 5px;
    border-radius:6px;
    color: #fff;
    font-family: 'Oswald';
    font-size: 20px;
    text-decoration: none;
    cursor: pointer;
    border:none;
}



#submit:hover {
    border: none;
    background:red;
    box-shadow: 0px 0px 1px #777;
}

If you're wondering how to get the file content from each ZipEntry it's actually quite simple. Here's a sample code:

public static void main(String[] args) throws IOException {
    ZipFile zipFile = new ZipFile("C:/test.zip");

    Enumeration<? extends ZipEntry> entries = zipFile.entries();

    while(entries.hasMoreElements()){
        ZipEntry entry = entries.nextElement();
        InputStream stream = zipFile.getInputStream(entry);
    }
}

Once you have the InputStream you can read it however you want.

You can use CSS grid to achieve this, this is the long-hand version for the purposes of illustration:

div.container {_x000D_
    display: grid;_x000D_
    grid-template-columns: 220px 20px auto;_x000D_
    grid-template-rows: auto;_x000D_
}_x000D_
_x000D_
div.left {_x000D_
    grid-column-start: 1;_x000D_
    grid-column-end: 2;_x000D_
    grid-row-start: row1-start_x000D_
    grid-row-end: 3;_x000D_
    background-color: Aqua;_x000D_
}_x000D_
_x000D_
div.right {_x000D_
    grid-column-start: 3;_x000D_
    grid-column-end: 4;_x000D_
    grid-row-start: 1;_x000D_
    grid-row-end; 1;_x000D_
    background-color: Silver;_x000D_
}_x000D_
_x000D_
div.below {_x000D_
    grid-column-start: 1;_x000D_
    grid-column-end: 4;_x000D_
    grid-row-start: 2;_x000D_
    grid-row-end; 2;_x000D_
}

<div class="container">_x000D_
    <div class="left">Left</div>_x000D_
    <div class="right">Right</div>_x000D_
    <div class="below">Below</div>_x000D_
</div>

Or the more traditional method using float and margin.

I have included a background colour in this example to help show where things are - and also what to do with content below the floated-area.

Don't put your styles inline in real life, extract them into a style sheet.

div.left {_x000D_
    width: 200px;_x000D_
    float: left;_x000D_
    background-color: Aqua;_x000D_
}_x000D_
_x000D_
div.right {_x000D_
    margin-left: 220px;_x000D_
    background-color: Silver;_x000D_
}_x000D_
_x000D_
div.clear {_x000D_
    clear: both;_x000D_
}

    <div class="left"> Left </div>_x000D_
    <div class="right"> Right </div>_x000D_
    <div class="clear">Below</div>

<div style="width: 200px; float: left; background-color: Aqua;"> Left </div>
<div style="margin-left: 220px; background-color: Silver;"> Right </div>
<div style="clear: both;">Below</div>

Here's a dplyr option:

library(dplyr)

# across all columns:
df %>% filter_all(any_vars(. %in% c('M017', 'M018')))

# or in only select columns:
df %>% filter_at(vars(col1, col2), any_vars(. %in% c('M017', 'M018')))                                                                                                     

T = [L[i] for i in Idx]

print "Number of lines: $nids\n";
print "Content: $ids\n";

How did Perl complain? print $ids should work, though you probably want a newline at the end, either explicitly with print as above or implicitly by using say or -l/$\.

If you want to interpolate a variable in a string and have something immediately after it that would looks like part of the variable but isn't, enclose the variable name in {}:

print "foo${ids}bar";

    $( "#datepicker" ).datepicker({ startDate: new Date("2019-10-15")});_x000D_
});

<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>_x000D_
<link href="https://cdnjs.cloudflare.com/ajax/libs/datepicker/0.6.5/datepicker.min.css" rel="stylesheet"/>_x000D_
<script src="https://cdnjs.cloudflare.com/ajax/libs/datepicker/0.6.5/datepicker.min.js"></script>_x000D_
_x000D_
<div> Select Date <input type="text" id="datepicker" /></div>

This will disable all days before the date 15th October 2019 (2019-10-15)

To use center alignment in ionic app code itself, you can use the following code:

<ion-row center>  
 <ion-col text-center>   
  <button ion-button>Search</button>  
 </ion-col> 
</ion-row>

To use right alignment in ionic app code itself, you can use the following code:

<ion-row right>  
 <ion-col text-right>   
  <button ion-button>Search</button>  
 </ion-col> 
</ion-row>

Change

JSONObject objects = getArray.getJSONArray(i);

to

JSONObject objects = getArray.getJSONObject(i);

or to

JSONObject objects = getArray.optJSONObject(i);

depending on which JSON-to/from-Java library you're using. (It looks like getJSONObject will work for you.)

Then, to access the string elements in the "objects" JSONObject, get them out by element name.

String a = objects.get("A");

If you need the names of the elements in the JSONObject, you can use the static utility method JSONObject.getNames(JSONObject) to do so.

String[] elementNames = JSONObject.getNames(objects);

"Get the value for the first element and the value for the last element."

If "element" is referring to the component in the array, note that the first component is at index 0, and the last component is at index getArray.length() - 1.

I want to iterate though the objects in the array and get thier component and thier value. In my example the first object has 3 components, the scond has 5 and the third has 4 components. I want iterate though each of them and get thier component name and value.

The following code does exactly that.

import org.json.JSONArray;
import org.json.JSONObject;

public class Foo
{
  public static void main(String[] args) throws Exception
  {
    String jsonInput = "{\"JObjects\":{\"JArray1\":[{\"A\":\"a\",\"B\":\"b\",\"C\":\"c\"},{\"A\":\"a1\",\"B\":\"b2\",\"C\":\"c3\",\"D\":\"d4\",\"E\":\"e5\"},{\"A\":\"aa\",\"B\":\"bb\",\"C\":\"cc\",\"D\":\"dd\"}]}}";

    // "I want to iterate though the objects in the array..."
    JSONObject outerObject = new JSONObject(jsonInput);
    JSONObject innerObject = outerObject.getJSONObject("JObjects");
    JSONArray jsonArray = innerObject.getJSONArray("JArray1");
    for (int i = 0, size = jsonArray.length(); i < size; i++)
    {
      JSONObject objectInArray = jsonArray.getJSONObject(i);

      // "...and get thier component and thier value."
      String[] elementNames = JSONObject.getNames(objectInArray);
      System.out.printf("%d ELEMENTS IN CURRENT OBJECT:\n", elementNames.length);
      for (String elementName : elementNames)
      {
        String value = objectInArray.getString(elementName);
        System.out.printf("name=%s, value=%s\n", elementName, value);
      }
      System.out.println();
    }
  }
}
/*
OUTPUT:
3 ELEMENTS IN CURRENT OBJECT:
name=A, value=a
name=B, value=b
name=C, value=c

5 ELEMENTS IN CURRENT OBJECT:
name=D, value=d4

I used AndExplorer for this purpose and my solution is popup a dialog and then redirect on the market to install the misssing application:

My startCreation is trying to call external file/directory picker. If it is missing call show installResultMessage function.

private void startCreation(){
    Intent intent = new Intent();
    intent.setAction(Intent.ACTION_PICK);
    Uri startDir = Uri.fromFile(new File("/sdcard"));

    intent.setDataAndType(startDir,
            "vnd.android.cursor.dir/lysesoft.andexplorer.file");
    intent.putExtra("browser_filter_extension_whitelist", "*.csv");
    intent.putExtra("explorer_title", getText(R.string.andex_file_selection_title));
    intent.putExtra("browser_title_background_color",
            getText(R.string.browser_title_background_color));
    intent.putExtra("browser_title_foreground_color",
            getText(R.string.browser_title_foreground_color));
    intent.putExtra("browser_list_background_color",
            getText(R.string.browser_list_background_color));
    intent.putExtra("browser_list_fontscale", "120%");
    intent.putExtra("browser_list_layout", "2");

    try{
         ApplicationInfo info = getPackageManager()
                                 .getApplicationInfo("lysesoft.andexplorer", 0 );

            startActivityForResult(intent, PICK_REQUEST_CODE);
    } catch( PackageManager.NameNotFoundException e ){
        showInstallResultMessage(R.string.error_install_andexplorer);
    } catch (Exception e) {
        Log.w(TAG, e.getMessage());
    }
}

This methos is just pick up a dialog and if user wants install the external application from market

private void showInstallResultMessage(int msg_id) {
    AlertDialog dialog = new AlertDialog.Builder(this).create();
    dialog.setMessage(getText(msg_id));
    dialog.setButton(getText(R.string.button_ok),
            new DialogInterface.OnClickListener() {

                @Override
                public void onClick(DialogInterface dialog, int which) {
                    finish();
                }
            });
    dialog.setButton2(getText(R.string.button_install),
            new DialogInterface.OnClickListener() {

                @Override
                public void onClick(DialogInterface dialog, int which) {
                    Intent intent = new Intent(Intent.ACTION_VIEW);
                    intent.setData(Uri.parse("market://details?id=lysesoft.andexplorer"));
                    startActivity(intent);
                    finish();
                }
            });
    dialog.show();
}

I think it's possible in Java 9:

animalMap.entrySet().stream()
                .forEach(
                        pair -> Optional.ofNullable(pair.getValue())
                                .ifPresentOrElse(v -> myMap.put(pair.getKey(), v), v -> myList.add(pair.getKey())))
                );

Need the ifPresentOrElse for it to work though. (I think a for loop looks better.)

You're probably going to have to break up your timestamp into ymd:HM and use DIV 5 to split the minutes up into 5-minute bins -- something like

select year(a.timestamp), 
       month(a.timestamp), 
       hour(a.timestamp), 
       minute(a.timestamp) DIV 5,
       name, 
       count(b.name)
FROM time a, id b
WHERE a.user = b.user AND a.id = b.id AND b.name = 'John' 
      AND a.timestamp BETWEEN '2010-11-16 10:30:00' AND '2010-11-16 11:00:00'
GROUP BY year(a.timestamp), 
       month(a.timestamp), 
       hour(a.timestamp), 
       minute(a.timestamp) DIV 12

...and then futz the output in client code to appear the way you like it. Or, you can build up the whole date string using the sql concat operatorinstead of getting separate columns, if you like.

select concat(year(a.timestamp), "-", month(a.timestamp), "-" ,day(a.timestamp), 
       " " , lpad(hour(a.timestamp),2,'0'), ":", 
       lpad((minute(a.timestamp) DIV 5) * 5, 2, '0'))

...and then group on that

If you are doing this in a browser, you can capture keyboard events.

• keydown
• keypress
• keyup

Can all be listened to on HTML nodes in most browsers.

Webkit also supports...

• textInput

See for more details .. http://unixpapa.com/js/key.html

In the particular situation outlined in the question,

typeof window.console === "undefined"

is identical to

window.console === undefined

I prefer the latter since it's shorter.

Please note that we look up for console only in global scope (which is a window object in all browsers). In this particular situation it's desirable. We don't want console defined elsewhere.

@BrianKelley in his great answer explains technical details. I've only added lacking conclusion and digested it into something easier to read.

When it is on server side, use web services - maybe RESTful with JSON.

• create a web service (for example with Tomcat)
• call its URL from JavaScript (for example with JQuery or dojo)

When Java code is in applet you can use JavaScript bridge. The bridge between the Java and JavaScript programming languages, known informally as LiveConnect, is implemented in Java plugin. Formerly Mozilla-specific LiveConnect functionality, such as the ability to call static Java methods, instantiate new Java objects and reference third-party packages from JavaScript, is now available in all browsers.

Below is example from documentation. Look at methodReturningString.

Java code:

public class MethodInvocation extends Applet {
    public void noArgMethod() { ... }
    public void someMethod(String arg) { ... }
    public void someMethod(int arg) { ... }
    public int  methodReturningInt() { return 5; }
    public String methodReturningString() { return "Hello"; }
    public OtherClass methodReturningObject() { return new OtherClass(); }
}

public class OtherClass {
    public void anotherMethod();
}

Web page and JavaScript code:

<applet id="app"
        archive="examples.jar"
        code="MethodInvocation" ...>
</applet>
<script language="javascript">
    app.noArgMethod();
    app.someMethod("Hello");
    app.someMethod(5);
    var five = app.methodReturningInt();
    var hello = app.methodReturningString();
    app.methodReturningObject().anotherMethod();
</script>

Here's a quick code snippet that will find the first non-empty line in a string:

string line1;
while (
    ((line1 = sr.ReadLine()) != null) &&
    ((line1 = line1.Trim()).Length == 0)
)
{ /* Do nothing - just trying to find first non-empty line*/ }

if(line1 == null){ /* Error - no non-empty lines in string */ }

The following function calculates the Z score:

def standardization(dataset):
  """ Standardization of numeric fields, where all values will have mean of zero 
  and standard deviation of one. (z-score)

  Args:
    dataset: A `Pandas.Dataframe` 
  """
  dtypes = list(zip(dataset.dtypes.index, map(str, dataset.dtypes)))
  # Normalize numeric columns.
  for column, dtype in dtypes:
      if dtype == 'float32':
          dataset[column] -= dataset[column].mean()
          dataset[column] /= dataset[column].std()
  return dataset

By design the body content in ASP.NET Web API is treated as forward-only stream that can be read only once.

The first read in your case is being done when Web API is binding your model, after that the Request.Content will not return anything.

You can remove the contact from your action parameters, get the content and deserialize it manually into object (for example with Json.NET):

[HttpPut]
public HttpResponseMessage Put(int accountId)
{
    HttpContent requestContent = Request.Content;
    string jsonContent = requestContent.ReadAsStringAsync().Result;
    CONTACT contact = JsonConvert.DeserializeObject<CONTACT>(jsonContent);
    ...
}

That should do the trick (assuming that accountId is URL parameter so it will not be treated as content read).

i've solved this issue with these steps: expand your project, right click "JRE System Library" > Properties > choose 3rd option "Workspace default JRE" > OK . Hope it help you too

To find table dependencies you can use the sys.sql_expression_dependencies catalog view:

SELECT 
referencing_object_name = o.name, 
referencing_object_type_desc = o.type_desc, 
referenced_object_name = referenced_entity_name, 
referenced_object_type_desc =so1.type_desc 
FROM sys.sql_expression_dependencies sed 
INNER JOIN sys.views o ON sed.referencing_id = o.object_id 
LEFT OUTER JOIN sys.views so1 ON sed.referenced_id =so1.object_id 
WHERE referenced_entity_name = 'Person'  

You can also try out ApexSQL Search a free SSMS and VS add-in that also has the View Dependencies feature. The View Dependencies feature has the ability to visualize all SQL database objects’ relationships, including those between encrypted and system objects, SQL server 2012 specific objects, and objects stored in databases encrypted with Transparent Data Encryption (TDE)

Disclaimer: I work for ApexSQL as a Support Engineer

I have run into the same error entries in LogCat. In my case it's caused by the 3rd party keyboard I am using. When I change it back to Android keyboard, the error entry does not show up any more.

//start the program
var express = require('express');
var app = express();

app.get('/', function (req, res) {

    var sql = require("mssql");

    // config for your database
    var config = {
        user: 'datapullman',
        password: 'system',
        server: 'localhost', 
        database: 'chat6' 
    };

    // connect to your database
    sql.connect(config, function (err) {

        if (err) console.log(err);

        // create Request object
        var request = new sql.Request();

        // query to the database and get the records

        request.query("select * From emp", function (err, recordset) {            
            if  (err) console.log(err)

            // send records as a response
            res.send(recordset);

        });
    });
});

var server = app.listen(5000, function () {
    console.log('Server is running..');
});

//create a table as emp in a database (i have created as chat6)

// programs ends here

//save it as app.js and run as node app.js //open in you browser as localhost:5000

You need to use a search algorithm on your array. It depends on how large is your array, you have plenty of choices on what to use. Or you can use on of the built in functions:

UPDATE

The Google maps API v2 is now installed on the latest Google system images (api:19 ARM or x86).
So your application should just work with the new images. There is no need to install these files.

I've been trying to run an Android Google Maps V2 application under an emulator and once I finally got Google Play Services running, I updated my SDK to Google Play Services revision 4, and my emulator wouldn't run my application any more.

I have now worked out how to update my emulator from my transformer tablet. (You won't need a tablet as you can download the files below.)

I used Titanium Backup to backup my Asus Eee Pad Transformer (TF101) and then grabbed the com.android.vending and the com.google.android.gms APK files from the backup.

I installed these on an emulator configured with platform: 4.1.2, API Level: 16, CPU Intel/Atom x86) and my Google Maps V2 application works again.

That was all .. none of the other steps regarding /system/app were required.

My application only uses the Google Maps API, no doubt, more steps are required if you use other Google Play services.

New files for latest Google Play services:

• com.google.android.gms-20140218.apk

• com.android.vending-20140218.apk

Same instructions as before: Create a new emulator with any CPU/ABI, a non-Google API target (versions 10-19 work) and GPU emulation on or off, and then install the files:

adb install com.android.vending-20140218.apk
adb install com.google.android.gms-20140218.apk

If you are upgrading an existing emulator then you might need to uninstall previous versions by:

adb uninstall com.android.vending
adb uninstall com.google.android.gms

That's all.

I see all answers recommend using str(object). It might fail if your object have more than ascii characters and you will see error like ordinal not in range(128). This was the case for me while I was converting list of string in language other than English

I resolved it by using unicode(object)

Sven Marnach excellent solution is directly translatable into ElementTree which is part of recent Python distributions:

from xml.etree import ElementTree as ET

s = """<table>
  <tr><th>Event</th><th>Start Date</th><th>End Date</th></tr>
  <tr><td>a</td><td>b</td><td>c</td></tr>
  <tr><td>d</td><td>e</td><td>f</td></tr>
  <tr><td>g</td><td>h</td><td>i</td></tr>
</table>
"""

table = ET.XML(s)
rows = iter(table)
headers = [col.text for col in next(rows)]
for row in rows:
    values = [col.text for col in row]
    print(dict(zip(headers, values)))

same output as Sven Marnach's answer...

That looks very unsafe (very little synchronization); how about something like:

class SizeQueue<T>
{
    private readonly Queue<T> queue = new Queue<T>();
    private readonly int maxSize;
    public SizeQueue(int maxSize) { this.maxSize = maxSize; }

    public void Enqueue(T item)
    {
        lock (queue)
        {
            while (queue.Count >= maxSize)
            {
                Monitor.Wait(queue);
            }
            queue.Enqueue(item);
            if (queue.Count == 1)
            {
                // wake up any blocked dequeue
                Monitor.PulseAll(queue);
            }
        }
    }
    public T Dequeue()
    {
        lock (queue)
        {
            while (queue.Count == 0)
            {
                Monitor.Wait(queue);
            }
            T item = queue.Dequeue();
            if (queue.Count == maxSize - 1)
            {
                // wake up any blocked enqueue
                Monitor.PulseAll(queue);
            }
            return item;
        }
    }
}

(edit)

In reality, you'd want a way to close the queue so that readers start exiting cleanly - perhaps something like a bool flag - if set, an empty queue just returns (rather than blocking):

bool closing;
public void Close()
{
    lock(queue)
    {
        closing = true;
        Monitor.PulseAll(queue);
    }
}
public bool TryDequeue(out T value)
{
    lock (queue)
    {
        while (queue.Count == 0)
        {
            if (closing)
            {
                value = default(T);
                return false;
            }
            Monitor.Wait(queue);
        }
        value = queue.Dequeue();
        if (queue.Count == maxSize - 1)
        {
            // wake up any blocked enqueue
            Monitor.PulseAll(queue);
        }
        return true;
    }
}

Add the following to your ~/.bashrc file. Log-out and log-in. I have my sdk in $HOME/Documents/Android/sdk you have to replace it with where you keep your sdk folder

git-pull - Fetch from and merge with another repository or a local branch
SYNOPSIS

git pull   …
DESCRIPTION

Runs git-fetch with the given parameters, and calls git-merge to merge the 
retrieved head(s) into the current branch. With --rebase, calls git-rebase 
instead of git-merge.

Note that you can use . (current directory) as the <repository> to pull 
from the local repository — this is useful when merging local branches 
into the current branch.

Also note that options meant for git-pull itself and underlying git-merge 
must be given before the options meant for git-fetch.

You would pull if you want the histories merged, you'd fetch if you just 'want the codez' as some person has been tagging some articles around here.

Just create a new branch with git checkout -b ABC_1; your uncommitted changes will be kept, and you then commit them to that branch.

Interestingly, you can also use the using/IDisposable pattern for other interesting things (such as the other point of the way that Rhino Mocks uses it). Basically, you can take advantage of the fact that the compiler will always call .Dispose on the "used" object. If you have something that needs to happen after a certain operation ... something that has a definite start and end ... then you can simply make an IDisposable class that starts the operation in the constructor, and then finishes in the Dispose method.

This allows you to use the really nice using syntax to denote the explicit start and end of said operation. This is also how the System.Transactions stuff works.

Running composer dump-autoload solves it for me.

If you're using .NET 3.5 SP1+ the better way to do this is to take a look at the

System.DirectoryServices.AccountManagement namespace.

It has methods to find people and you can pretty much pass in any username format you want and then returns back most of the basic information you would need. If you need help on loading the more complex objects and properties check out the source code for http://umanage.codeplex.com its got it all.

If you run pub build --mode=debug the build directory contains the application without symlinks. The Dart code should be retained when --mode=debug is used.

Here is some discussion going on about this topic too Dart and it's place in Rails Assets Pipeline

You're already doing it!

save() will check if something in the model has changed. If it hasn't it won't run a db query.

Here's the relevant part of code in Illuminate\Database\Eloquent\Model@performUpdate:

protected function performUpdate(Builder $query, array $options = [])
{
    $dirty = $this->getDirty();

    if (count($dirty) > 0)
    {
        // runs update query
    }

    return true;
}

The getDirty() method simply compares the current attributes with a copy saved in original when the model is created. This is done in the syncOriginal() method:

public function __construct(array $attributes = array())
{
    $this->bootIfNotBooted();

    $this->syncOriginal();

    $this->fill($attributes);
}

public function syncOriginal()
{
    $this->original = $this->attributes;

    return $this;
}

If you want to check if the model is dirty just call isDirty():

if($product->isDirty()){
    // changes have been made
}

Or if you want to check a certain attribute:

if($product->isDirty('price')){
    // price has changed
}

You need a With statement prior to this. Or make the .Cells into Cells

Use attribute binding syntax instead

<ol class="viewer-nav"><li *ngFor="let section of sections" 
    [attr.data-sectionvalue]="section.value">{{ section.text }}</li>  
</ol>

or

<ol class="viewer-nav"><li *ngFor="let section of sections" 
    attr.data-sectionvalue="{{section.value}}">{{ section.text }}</li>  
</ol>

You can also get your wanted time using the following JS code:

new Date(`${post.data.created_at} GMT+0200`)

In this example, my received dates were in GMT+0200 timezone. Instead of it can be every single timezone. And the returned data will be the date in your timezone. Hope this will help anyone to save time

If the original Service .InstallLog and .InstallState files are still in the folder, you can try reinstalling the executable to replace the files, then use InstallUtil /u, then uninstall the program. It's a bit convoluted, but worked in a particular instance for me.

This works for me, with Mac OS Sierra using Python,

options = webdriver.ChromeOptions()
options.add_argument("--kiosk")
driver = webdriver.Chrome(chrome_options=options)

This is not right. Here's how you should use Runtime.exec(). You might also try its more modern cousin, ProcessBuilder:

EASIEST SOLUTION - USE SVG

Works in: in IE9, IE10, FF, Chrome, Safari

(if you are using other browsers please "Run code snippet" and place a comment)

No external dependencies besides Google Maps API!

This is quite easy provided that you have your icon in .svg format. If that is the case just add appropriate text element and change its content to fit your needs with JS.

Add something like this to your .svg code (this is text "section" which will be later changed with JS):

Important: Use correct <text> tag properties. Note text-anchor="middle" x="50%" y="28" which center longer numbers (more info: How to place and center text in an SVG rectangle)

Use encodeURIComponent() (this probably ensures compatibility with IE9 and 10)

You are opening the file as "w", which stands for writable.

Using "w" you won't be able to read the file. Use the following instead:

file = open("File.txt","r")

Additionally, here are the other options:

"r"   Opens a file for reading only.
"r+"  Opens a file for both reading and writing.
"rb"  Opens a file for reading only in binary format.
"rb+" Opens a file for both reading and writing in binary format.
"w"   Opens a file for writing only.
"a"   Open for writing.  The file is created if it does not exist.
"a+"  Open for reading and writing.  The file is created if it does not exist.

Check if the user has scrolled past the header ad, then display the footer ad.

if($(your header ad).position().top < 0) { $(your footer ad).show() }

Am I correct at what you are looking for?

$ echo "C:\Windows\Folder\File.txt" | sed -e 's/\\/\//g'
C:/Windows/Folder/File.txt

The sed command in this case is 's/OLD_TEXT/NEW_TEXT/g'.

The leading 's' just tells it to search for OLD_TEXT and replace it with NEW_TEXT.

The trailing 'g' just says to replace all occurrences on a given line, not just the first.

And of course you need to separate the 's', the 'g', the old, and the new from each other. This is where you must use forward slashes as separators.

For your case OLD_TEXT == '\' and NEW_TEXT == '/'. But you can't just go around typing slashes and expecting things to work as expected be taken literally while using them as separators at the same time. In general slashes are quite special and must be handled as such. They must be 'escaped' (i.e. preceded) by a backslash.

So for you, OLD_TEXT == '\\' and NEW_TEXT == '\/'. Putting these inside the 's/OLD_TEXT/NEW_TEXT/g' paradigm you get
's/\\/\//g'. That reads as
's / \\ / \/ / g' and after escapes is
's / \ / / / g' which will replace all backslashes with forward slashes.

Try this one:

$this->db->select("*");
$this->db->where_in("(SELECT trans_id FROM myTable WHERE code = 'B')");
$this->db->where('code !=', 'B');
$this->db->get('myTable');

Note: $this->db->select("*"); is optional when you are selecting all columns from table

grep is the right tool for extracting.

using your example and your regex:

kent$  echo 'foo bar <foo> bla 1 2 3.4'|grep -o '[0-9][0-9]*[\ \t][0-9.]*[\ \t]*$'
2 3.4

I really don't understand why python still doesn't have such a function. I also don't agree to use the following

f.tell() == os.fstat(f.fileno()).st_size

The main reason is f.tell() doesn't likely to work for some special conditions.

The method works for me is like the following. If you have some pseudocode like the following

while not EOF(f):
     line = f.readline()
     " do something with line"

You can replace it with:

lines = iter(f.readlines())
while True:
     try:
        line = next(lines)
        " do something with line"
     except StopIteration:
        break

This method is simple and you don't need to change most of you code.

Your methods don't refer to an object (that is, self), so you should use the @staticmethod decorator:

class MathsOperations:
    @staticmethod
    def testAddition (x, y):
        return x + y

    @staticmethod
    def testMultiplication (a, b):
        return a * b

I'm not sure what you're doing, but this will go from JSON to CSV using JavaScript. This is using the open source JSON library, so just download JSON.js into the same folder you saved the code below into, and it will parse the static JSON value in json3 into CSV and prompt you to download/open in Excel.

I had the same issue after I tried to restart mysql.

I use the following two aliases in my .profile for convenience

alias mysql-stop='launchctl unload ~/Library/LaunchAgents/homebrew.mxcl.mysql.plist'
alias mysql-start='launchctl load ~/Library/LaunchAgents/homebrew.mxcl.mysql.plist' 

After stoping mysql and then trying to restart I experienced the issue you were having. I looked into the launchctl load and it was reporting a “nothing found to load” error.

After a quick search I found this..

http://www.daveoncode.com/2013/02/01/solve-mac-osx-launchctl-nothing-found-to-load-error/

So I updated me mysql-start alias as follows

alias mysql-start='launchctl load -w -F ~/Library/LaunchAgents/homebrew.mxcl.mysql.plist'

This solved my issue which may be useful for you.

As Internet Explorer doesn't natively support rounded corners. So a better cross-browser way to handle it would be to use rounded-corner images at the corners. Many famous websites use this approach.

You can also find rounded image generators around the web. One such link is http://www.generateit.net/rounded-corner/

I actually found a better way to send files using HttpURLConnection using MultipartEntity

private static String multipost(String urlString, MultipartEntity reqEntity) {
    try {
        URL url = new URL(urlString);
        HttpURLConnection conn = (HttpURLConnection) url.openConnection();
        conn.setReadTimeout(10000);
        conn.setConnectTimeout(15000);
        conn.setRequestMethod("POST");
        conn.setUseCaches(false);
        conn.setDoInput(true);
        conn.setDoOutput(true);

        conn.setRequestProperty("Connection", "Keep-Alive");
        conn.addRequestProperty("Content-length", reqEntity.getContentLength()+"");
        conn.addRequestProperty(reqEntity.getContentType().getName(), reqEntity.getContentType().getValue());

        OutputStream os = conn.getOutputStream();
        reqEntity.writeTo(conn.getOutputStream());
        os.close();
        conn.connect();

        if (conn.getResponseCode() == HttpURLConnection.HTTP_OK) {
            return readStream(conn.getInputStream());
        }

    } catch (Exception e) {
        Log.e(TAG, "multipart post error " + e + "(" + urlString + ")");
    }
    return null;        
}

private static String readStream(InputStream in) {
    BufferedReader reader = null;
    StringBuilder builder = new StringBuilder();
    try {
        reader = new BufferedReader(new InputStreamReader(in));
        String line = "";
        while ((line = reader.readLine()) != null) {
            builder.append(line);
        }
    } catch (IOException e) {
        e.printStackTrace();
    } finally {
        if (reader != null) {
            try {
                reader.close();
            } catch (IOException e) {
                e.printStackTrace();
            }
        }
    }
    return builder.toString();
} 

Assuming you are uploading an image with bitmap data:

    Bitmap bitmap = ...;
    String filename = "filename.png";
    ByteArrayOutputStream bos = new ByteArrayOutputStream();
    bitmap.compress(Bitmap.CompressFormat.PNG, 100, bos);
    ContentBody contentPart = new ByteArrayBody(bos.toByteArray(), filename);

    MultipartEntity reqEntity = new MultipartEntity(HttpMultipartMode.BROWSER_COMPATIBLE);
    reqEntity.addPart("picture", contentPart);
    String response = multipost("http://server.com", reqEntity);

And Voila! Your post data will contain picture field along with the filename and path on your server.

In cmd

C:\Users\Downloads>install.exe LAX_VM "C:\Program Files\Java\jdk1.8.0_60\bin\java.exe"

Not sure why the question was down-voted, but I had the same issue and following the blog post recommended solve the issue. One thing I should add is that in my case, once I ran:

npm config set prefix /usr/local

I confirmed the npm root -g was pointing to /usr/local/lib/node_modules/npm, but in order to install gulp in /usr/local/lib/node_modules, I had to use sudo:

sudo npm install gulp -g

The simplest way is to generate a random nuber between 0-1 then strech it by multiplying, and shifting it.
So yo would multiply by (x-y) so the result is in the range of 0 to x-y,
Then add x and you get the random number between x and y.

To get a five multiplier use rounding. If this is unclear let me know and I'll add code snippets.

There is a Simple Solution You can Try this code

    String s = "hju   vg    jhdgsf  dh gg    g g  g  ";

    String[] words = s.trim().split("\\s+");

    System.out.println("count is = "+(words.length));

Try putting the search condition in a bracket, as shown below. This returns the result of the conditional query inside the bracket. Then test its result to determine if it is negative (i.e. it does not belong to any of the options in the vector), by setting it to FALSE.

SE_CSVLinelist_filtered <- filter(SE_CSVLinelist_clean, 
(where_case_travelled_1 %in% c('Outside Canada','Outside province/territory of residence but within Canada')) == FALSE)

In the definition of your Card class, a declaration for a default construction appears:

class Card
{
    // ...

    Card(); // <== Declaration of default constructor!

    // ...
};

But no corresponding definition is given. In fact, this function definition (from card.cpp):

void Card() {
//nothing
}

Does not define a constructor, but rather a global function called Card that returns void. You probably meant to write this instead:

Card::Card() {
//nothing
}

Unless you do that, since the default constructor is declared but not defined, the linker will produce error about undefined references when a call to the default constructor is found.

The same applies to your constructor accepting two arguments. This:

void Card(Card::Rank rank, Card::Suit suit) {
    cardRank = rank;
    cardSuit = suit;
}

Should be rewritten into this:

Card::Card(Card::Rank rank, Card::Suit suit) {
    cardRank = rank;
    cardSuit = suit;
}

And the same also applies for other member functions: it seems you did not add the Card:: qualifier before the member function names in their definitions. Without it, those functions are global functions rather than definitions of member functions.

Your destructor, on the other hand, is declared but never defined. Just provide a definition for it in card.cpp:

Card::~Card() { }

Try this. It is in VB.net and you need to convert it to Javascript. This function accepts parameters in decimal minutes.

Have you tried this??

$("Textbox").rules("add", { regex: "^[a-zA-Z'.\\s]{1,40}$", messages: { regex: "The text is invalid..." } })

Note: make sure to escape all the "\" of ur regex by adding another "\" in front of them else the regex wont work as expected.

These are the steps you can follow when you are on a shared hosting environment and need to install & compile Python from source and then create venv from your Python version. For Python 2.7.9. you would do something along these lines:

mkdir ~/src
wget http://www.python.org/ftp/python/2.7.9/Python-2.7.9.tgz
tar -zxvf Python-2.7.9.tgz
cd Python-2.7.9
mkdir ~/.localpython
./configure --prefix=$HOME/.localpython
make
make install

virtual env

cd ~/src
wget https://pypi.python.org/packages/5c/79/5dae7494b9f5ed061cff9a8ab8d6e1f02db352f3facf907d9eb614fb80e9/virtualenv-15.0.2.tar.gz#md5=0ed59863994daf1292827ffdbba80a63
tar -zxvf virtualenv-15.0.2.tar.gz
cd virtualenv-15.0.2/
~/.localpython/bin/python setup.py install
virtualenv ve -p $HOME/.localpython/bin/python2.7
source ve/bin/activate   

Naturally, this can be applicable to any situation where you want to replicate the exact environment you work and deploy on.

fc. fc is better at handling large files (> 4 GBytes) than Cygwin's diff.

It's quite clearly from their docs:

If you used componentWillReceiveProps for re-computing some data only when a prop changes, use a memoization helper instead.

Use: https://reactjs.org/blog/2018/06/07/you-probably-dont-need-derived-state.html#what-about-memoization

Probably not. While I can't log into the Apple Development site, according to this post you need an intel mac platform.

You could do this yourself by checking the output from pwd when running it. This will print the directory you are currently in. Not the script.

If your script does not switch directories, it'll print the directory you ran it from.

You can define:

Context ctx; 

And on onCreate initialise ctx to:

ctx=parent.getContext(); 

Note: Parent is a ViewGroup.

This is a modified version of Tim Post's method; I used /dev/tty instead of /dev/stdout. I don't know why it doesn't work with stdout (which is a link to /proc/self/fd/1):

freopen("log.txt","w",stdout);
...
...
freopen("/dev/tty","w",stdout);

By using /dev/tty the output is redirected to the terminal from where the app was launched.

Hope this info is useful.

Simplest is use list[i:i]

It's now possible to control which folder the packages are installed into.

http://nuget.codeplex.com/workitem/215

Edit: See Phil Haack's comment on Dec 10 2010 at 11:45 PM (in the work item/the link above). The support is partially implemented in 1.0, but is not documented.

According to @dfowler: Add a nuget.config file next to the solution with this:

<settings>
<repositoryPath>{some path here}</repositoryPath>
</settings>

There is a nuget package for creating the package folder override.

Update for version 2.1

As Azat commented, there is now official documentation on how to control the package locations. The release notes for 2.1 specifies the following configuration in a nuget.config file (see the release notes for a description of valid places to put the config files and how the hierarchical configuration model works):

<configuration>
  <config>
    <add key="repositoryPath" value="C:\thePathToMyPackagesFolder" />
  </config>
  ... 
</configuration>

This would change the packages folder for the configuration level you put the file in (solution if you put it in the solution directory, project in project directory and so on). Note that the release notes state:

[...] if you have an existing packages folder underneath your solution root, you will need to delete it before NuGet will place packages in the new location.

Java 8 Stream API can be used for the purpose,

ArrayList<String> list1 = new ArrayList<>();

list1.add("A");
list1.add("B");
list1.add("A");
list1.add("D");
list1.add("G");

ArrayList<String> list2 = new ArrayList<>();

list2.add("B");
list2.add("D");
list2.add("E");
list2.add("G");

List<String> noDup = Stream.concat(list1.stream(), list2.stream())
                     .distinct()
                     .collect(Collectors.toList());
noDup.forEach(System.out::println);

En passant, it shouldn't be forgetten that distinct() makes use of hashCode().

You can do shortcut via inline function if you want to simply change the state variable without declaring a new function at top:

<input type="text" onChange={e => this.setState({ text: e.target.value })}/>

Use config.to_prepare to load you monkey patches/extensions for every request in development mode.

config.to_prepare do |action_dispatcher|
 # More importantly, will run upon every request in development, but only once (during boot-up) in production and test.
 Rails.logger.info "\n--- Loading extensions for #{self.class} "
 Dir.glob("#{Rails.root}/lib/extensions/**/*.rb").sort.each do |entry|
   Rails.logger.info "Loading extension(s): #{entry}"
   require_dependency "#{entry}"
 end
 Rails.logger.info "--- Loaded extensions for #{self.class}\n"

end

You can use an array key => value style to use with strtr() safely for UTF-8 characters even if they are multi-bytes.

function no_accent($str){
    $accents = array('À' => 'A', 'Á' => 'A', 'Â' => 'A', 'Ã' => 'A', 'Ä' => 'A', 'Å' => 'A', 'à' => 'a', 'á' => 'a', 'â' => 'a', 'ã' => 'a', 'ä' => 'a', 'å' => 'a', 'A' => 'A', 'a' => 'a', 'A' => 'A', 'a' => 'a', 'A' => 'A', 'a' => 'a', 'Ç' => 'C', 'ç' => 'c', 'C' => 'C', 'c' => 'c', 'C' => 'C', 'c' => 'c', 'C' => 'C', 'c' => 'c', 'C' => 'C', 'c' => 'c', 'Ð' => 'D', 'ð' => 'd', 'D' => 'D', 'd' => 'd', 'Ð' => 'D', 'd' => 'd', 'È' => 'E', 'É' => 'E', 'Ê' => 'E', 'Ë' => 'E', 'è' => 'e', 'é' => 'e', 'ê' => 'e', 'ë' => 'e', 'E' => 'E', 'e' => 'e', 'E' => 'E', 'e' => 'e', 'E' => 'E', 'e' => 'e', 'E' => 'E', 'e' => 'e', 'E' => 'E', 'e' => 'e', 'G' => 'G', 'g' => 'g', 'G' => 'G', 'g' => 'g', 'G' => 'G', 'g' => 'g', 'G' => 'G', 'g' => 'g', 'H' => 'H', 'h' => 'h', 'H' => 'H', 'h' => 'h', 'Ì' => 'I', 'Í' => 'I', 'Î' => 'I', 'Ï' => 'I', 'ì' => 'i', 'í' => 'i', 'î' => 'i', 'ï' => 'i', 'I' => 'I', 'i' => 'i', 'I' => 'I', 'i' => 'i', 'I' => 'I', 'i' => 'i', 'I' => 'I', 'i' => 'i', 'I' => 'I', 'i' => 'i', 'J' => 'J', 'j' => 'j', 'K' => 'K', 'k' => 'k', '?' => 'k', 'L' => 'L', 'l' => 'l', 'L' => 'L', 'l' => 'l', 'L' => 'L', 'l' => 'l', '?' => 'L', '?' => 'l', 'L' => 'L', 'l' => 'l', 'Ñ' => 'N', 'ñ' => 'n', 'N' => 'N', 'n' => 'n', 'N' => 'N', 'n' => 'n', 'N' => 'N', 'n' => 'n', '?' => 'n', '?' => 'N', '?' => 'n', 'Ò' => 'O', 'Ó' => 'O', 'Ô' => 'O', 'Õ' => 'O', 'Ö' => 'O', 'Ø' => 'O', 'ò' => 'o', 'ó' => 'o', 'ô' => 'o', 'õ' => 'o', 'ö' => 'o', 'ø' => 'o', 'O' => 'O', 'o' => 'o', 'O' => 'O', 'o' => 'o', 'O' => 'O', 'o' => 'o', 'R' => 'R', 'r' => 'r', 'R' => 'R', 'r' => 'r', 'R' => 'R', 'r' => 'r', 'S' => 'S', 's' => 's', 'S' => 'S', 's' => 's', 'S' => 'S', 's' => 's', 'Š' => 'S', 'š' => 's', '?' => 's', 'T' => 'T', 't' => 't', 'T' => 'T', 't' => 't', 'T' => 'T', 't' => 't', 'Ù' => 'U', 'Ú' => 'U', 'Û' => 'U', 'Ü' => 'U', 'ù' => 'u', 'ú' => 'u', 'û' => 'u', 'ü' => 'u', 'U' => 'U', 'u' => 'u', 'U' => 'U', 'u' => 'u', 'U' => 'U', 'u' => 'u', 'U' => 'U', 'u' => 'u', 'U' => 'U', 'u' => 'u', 'U' => 'U', 'u' => 'u', 'W' => 'W', 'w' => 'w', 'Ý' => 'Y', 'ý' => 'y', 'ÿ' => 'y', 'Y' => 'Y', 'y' => 'y', 'Ÿ' => 'Y', 'Z' => 'Z', 'z' => 'z', 'Z' => 'Z', 'z' => 'z', 'Ž' => 'Z', 'ž' => 'z');
    return strtr($str, $accents);
}

Plus, you save decode/encode in UTF-8 part.

/<b>(.*?)<\/b>/g

Add g (global) flag after:

/<b>(.*?)<\/b>/g.exec(str)
             //^-----here it is 

However if you want to get all matched elements, then you need something like this:

var str = "<b>Bob</b>, I'm <b>20</b> years old, I like <b>programming</b>.";

var result = str.match(/<b>(.*?)<\/b>/g).map(function(val){
   return val.replace(/<\/?b>/g,'');
});
//result -> ["Bob", "20", "programming"] 

If an element has attributes, regexp will be:

/<b [^>]+>(.*?)<\/b>/g.exec(str)

I found it much easier to use tokens than SSH keys. I couldn't find much good documentation on this, so I came across this solution mainly through trial and error. Further, installing from pip and setuptools have some subtle differences; but this way should work for both.

GitHub don't (currently, as of August 2016) offer an easy way to get the zip / tarball of private repositories. So you need to point setuptools to tell setuptools that you're pointing to a Git repository:

from setuptools import setup
import os
# Get the deploy key from https://help.github.com/articles/git-automation-with-oauth-tokens/
github_token = os.environ['GITHUB_TOKEN']

setup(
    # ...
    install_requires='package',
    dependency_links = [
    'git+https://{github_token}@github.com/user/{package}.git/@{version}#egg={package}-0'
        .format(github_token=github_token, package=package, version=master)
        ]

A couple of notes here:

• For private repositories, you need to authenticate with GitHub; the simplest way I found is to create an OAuth token, drop that into your environment, and then include it with the URL
• You need to include some version number (here is 0) at the end of the link, even if there's isn't any package on PyPI. This has to be a actual number, not a word.
• You need to preface with git+ to tell setuptools it's to clone the repository, rather than pointing at a zip / tarball
• version can be a branch, a tag, or a commit hash
• You need to supply --process-dependency-links if installing from pip

EDIT: Please note that currently this will not work as this functionality does not yet exist in bootstrap. See issue here.

RunOnUIThread didn't seem to work for me but the following ended up solving my issues.

            _ = MainThread.InvokeOnMainThreadAsync(async () =>
           {
               this.LoadApplication(Startup.Init(this.ConfigureServices));

               var authenticationService = App.ServiceProvider.GetService<AuthenticationService>();
               if (authenticationService.AuthenticationResult == null)
               {
                   await authenticationService.AuthenticateAsync(AuthenticationUserFlow.SignUpSignIn, CrossCurrentActivity.Current.Activity).ConfigureAwait(false);
               }
           });

Within the Startup.Init method there is ReactiveUI routing and this needs to be invoked on the main thread. This Invoke method also accepts async/await better than RunOnUIThread.

So anywhere I need to invoke methods on the mainthread I use this.

Please comment on this if anyone knows something I don't and can help me improve my application.

The shorthand for $(document).ready(handler) is $(handler) (where handler is a function). See here.

The code in your question has nothing to do with .ready(). Rather, it is an immediately-invoked function expression (IIFE) with the jQuery object as its argument. Its purpose is to restrict the scope of at least the $ variable to its own block so it doesn't cause conflicts. You typically see the pattern used by jQuery plugins to ensure that $ == jQuery.

There is very little overall difference between GCC 4.8 and clang 3.3 in terms of speed of the resulting binary. In most cases code generated by both compilers performs similarly. Neither of these two compilers dominates the other one.

Benchmarks telling that there is a significant performance gap between GCC and clang are coincidental.

Program performance is affected by the choice of the compiler. If a developer or a group of developers is exclusively using GCC then the program can be expected to run slightly faster with GCC than with clang, and vice versa.

From developer viewpoint, a notable difference between GCC 4.8+ and clang 3.3 is that GCC has the -Og command line option. This option enables optimizations that do not interfere with debugging, so for example it is always possible to get accurate stack traces. The absence of this option in clang makes clang harder to use as an optimizing compiler for some developers.

Enter the command

which python

//output:
/usr/bin/python

cd /usr/bin
ls -l

Here you can see something like this

lrwxrwxrwx 1 root   root            9 Mar  7 17:04  python -> python2.7

your default python2.7 is soft linked to the text 'python'

So remove the softlink python

sudo rm -r python

then retry the above command

ls -l

you can see the softlink is removed

-rwxr-xr-x 1 root   root      3670448 Nov 12 20:01  python2.7

Then create a new softlink for python3.6

ln -s /usr/bin/python3.6 python

Then try the command python in terminal

//output:
Python 3.6.7 (default, Oct 22 2018, 11:32:17)

Here is something that might help. Use the root privileges. if you have .bin then simply add the execution permission to the bin file.

chmod a+x jdk*.bin

next step is to run the .bin file which is simply

./jdk*.bin in the location you want to install.

you are done.

Using a generator expression:

def magic(numbers):
    digits = ''.join(str(n) for n in numbers)
    return int(digits)

This is because of a higher JDK during compile time and lower JDK during runtime. So you just need to update your JDK version, possible to JDK 7

I built this script. It is in Yosemite and it is bash script using AppleScript to choose a list of users for SSH servers. Basically you define an IP and then the user names.. when the application launches it asks who you want to login in as.. the SSH terminal is launched and logged in prompting a password...

I highly recommend though; Nathan Pickmans post above about Shuttle (http://fitztrev.github.io/shuttle/).. a very smart and simple application.

It seems strange that you would write arrays without commas (is that a MATLAB syntax?)

Have you tried going through NumPy's documentation on multi-dimensional arrays?

It seems NumPy has a "Python-like" append method to add items to a NumPy n-dimensional array:

>>> p = np.array([[1,2],[3,4]])

>>> p = np.append(p, [[5,6]], 0)

>>> p = np.append(p, [[7],[8],[9]],1)

>>> p
array([[1, 2, 7], [3, 4, 8], [5, 6, 9]])

It has also been answered already...

From the documentation for MATLAB users:

You could use a matrix constructor which takes a string in the form of a matrix MATLAB literal:

mat("1 2 3; 4 5 6")

or

matrix("[1 2 3; 4 5 6]")

Please give it a try and tell me how it goes.

    public MainWindow()
    {
        // This button needs to exist on your form.
        myButton.Click += myButton_Click;
    }

    void myButton_Click(object sender, RoutedEventArgs e)
    {
        MessageBox.Show("Message here");
        this.Close();
    }

Actually even font-awesome CSS has a similar strategy for setting their icon styles. If you want to get a quick hold of the icon code, check the non-minified font-awesome.css file and there they are....each font in its purity.

Because I hate repeating complex logic, here's a generic version of Slauma's solution.

Here's my update method. Note that in a detached scenario, sometimes your code will read data and then update it, so it's not always detached.

public async Task UpdateAsync(TempOrder order)
{
    order.CheckNotNull(nameof(order));
    order.OrderId.CheckNotNull(nameof(order.OrderId));

    order.DateModified = _dateService.UtcNow;

    if (_context.Entry(order).State == EntityState.Modified)
    {
        await _context.SaveChangesAsync().ConfigureAwait(false);
    }
    else // Detached.
    {
        var existing = await SelectAsync(order.OrderId!.Value).ConfigureAwait(false);
        if (existing != null)
        {
            order.DateModified = _dateService.UtcNow;
            _context.TrackChildChanges(order.Products, existing.Products, (a, b) => a.OrderProductId == b.OrderProductId);
            await _context.SaveChangesAsync(order, existing).ConfigureAwait(false);
        }
    }
}

CheckNotNull is defined here.

Sure, use Enumerable.Distinct.

Given a collection of obj (e.g. foo), you'd do something like this:

var distinctTypeIDs = foo.Select(x => x.typeID).Distinct();

As long as the value of width is auto, the element can have horizontal margin, padding and border without becoming wider than its container (unless of course the sum of margin-left + border-left-width + padding-left + padding-right + border-right-width + margin-right is larger than the container). The width of its content box will be whatever is left when the margin, padding and border have been subtracted from the container’s width.

On the other hand, if you specify width:100%, the element’s total width will be 100% of its containing block plus any horizontal margin, padding and border (unless you’ve used box-sizing:border-box, in which case only margins are added to the 100% to change how its total width is calculated). This may be what you want, but most likely it isn’t.

Whilst the most upvoted answer is correct but it lacks usage of multi-core processing. In my case, having 12 cores I use PLink:

Parallel.ForEach(
    File.ReadLines(filename), //returns IEumberable<string>: lazy-loading
    new ParallelOptions { MaxDegreeOfParallelism = Environment.ProcessorCount },
    (line, state, index) =>
    {
        //process line value
    }
);

Worth mentioning, I got that as an interview question asking return Top 10 most occurrences:

var result = new ConcurrentDictionary<string, int>(StringComparer.InvariantCultureIgnoreCase);
Parallel.ForEach(
    File.ReadLines(filename),
    new ParallelOptions { MaxDegreeOfParallelism = Environment.ProcessorCount },
    (line, state, index) =>
    {
        result.AddOrUpdate(line, 1, (key, val) => val + 1);        
    }
);

return result
    .OrderByDescending(x => x.Value)
    .Take(10)
    .Select(x => x.Value);

Short answer:

@Autowired
private WebApplicationContext webApplicationContext;

@Autowired
private Filter springSecurityFilterChain;

@Before
public void setUp() throws Exception {
    final MockHttpServletRequestBuilder defaultRequestBuilder = get("/dummy-path");
    this.mockMvc = MockMvcBuilders.webAppContextSetup(this.webApplicationContext)
            .defaultRequest(defaultRequestBuilder)
            .alwaysDo(result -> setSessionBackOnRequestBuilder(defaultRequestBuilder, result.getRequest()))
            .apply(springSecurity(springSecurityFilterChain))
            .build();
}

private MockHttpServletRequest setSessionBackOnRequestBuilder(final MockHttpServletRequestBuilder requestBuilder,
                                                             final MockHttpServletRequest request) {
    requestBuilder.session((MockHttpSession) request.getSession());
    return request;
}

If you can't put value on buttons. I have just a rough solution. Put a hidden field. And when one of the buttons are clicked before submitting, populate the value of hidden field with like say 1 when first button clicked and 2 if second one is clicked. and in submit page check for the value of this hidden field to determine which one is clicked.

    from rest_framework import status
    from rest_framework.response import Response
    class FileUpload(APIView):
         def put(request):
             try:
                file = request.FILES['filename']
                #now upload to s3 bucket or your media file
             except Exception as e:
                   print e
                   return Response(status, 
                           status.HTTP_500_INTERNAL_SERVER_ERROR)
             return Response(status, status.HTTP_200_OK)

I was upgrading a legacy instance of jQuery UI and found that there was an extension to the dialog widget and it was simply using "center" instead of the position object. Implementing the position object or removing the parameter entirely worked for me (because center is the default).

In order to approach to Modular design pattern, you need to understand these concept first:

Immediately-Invoked Function Expression (IIFE):

(function() {
      // Your code goes here 
}());

There are two ways you can use the functions. 1. Function declaration 2. Function expression.

Here are using function expression.

What is namespace? Now if we add the namespace to the above piece of code then

var anoyn = (function() {
}());

What is closure in JS?

It means if we declare any function with any variable scope/inside another function (in JS we can declare a function inside another function!) then it will count that function scope always. This means that any variable in outer function will be read always. It will not read the global variable (if any) with the same name. This is also one of the objective of using modular design pattern avoiding naming conflict.

var scope = "I am global";
function whatismyscope() {
    var scope = "I am just a local";
    function func() {return scope;}
    return func;
}
whatismyscope()()

Now we will apply these three concepts I mentioned above to define our first modular design pattern:

var modularpattern = (function() {
    // your module code goes here
    var sum = 0 ;

    return {
        add:function() {
            sum = sum + 1;
            return sum;
        },
        reset:function() {
            return sum = 0;    
        }  
    }   
}());
alert(modularpattern.add());    // alerts: 1
alert(modularpattern.add());    // alerts: 2
alert(modularpattern.reset());  // alerts: 0

jsfiddle for the code above.

The objective is to hide the variable accessibility from the outside world.

Hope this helps. Good Luck.

You could use Spring Security Crypto (has only 2 optional compile dependencies), which supports PBKDF2, BCrypt, SCrypt and Argon2 password encryption.

Argon2PasswordEncoder argon2PasswordEncoder = new Argon2PasswordEncoder();
String aCryptedPassword = argon2PasswordEncoder.encode("password");
boolean passwordIsValid = argon2PasswordEncoder.matches("password", aCryptedPassword);

SCryptPasswordEncoder sCryptPasswordEncoder = new SCryptPasswordEncoder();
String sCryptedPassword = sCryptPasswordEncoder.encode("password");
boolean passwordIsValid = sCryptPasswordEncoder.matches("password", sCryptedPassword);

BCryptPasswordEncoder bCryptPasswordEncoder = new BCryptPasswordEncoder();
String bCryptedPassword = bCryptPasswordEncoder.encode("password");
boolean passwordIsValid = bCryptPasswordEncoder.matches("password", bCryptedPassword);

Pbkdf2PasswordEncoder pbkdf2PasswordEncoder = new Pbkdf2PasswordEncoder();
String pbkdf2CryptedPassword = pbkdf2PasswordEncoder.encode("password");
boolean passwordIsValid = pbkdf2PasswordEncoder.matches("password", pbkdf2CryptedPassword);

right click on the project create a file with name .ignore, then you can see that file opened.

at the right top of the file you can see install plugins or else you can install using plugins(plugin name - .ignore).

Now when ever you give a right click on the file or project you can see the option call add to .ignore

I have a similar table styled like so:

<table style="width:100%; table-layout:fixed">
    <tr>
        <td style="width: 150px">Hello, World!</td>
        <td>
            <div>
                <pre style="margin:0; overflow:scroll">My preformatted content</pre>
            </div>
        </td>
    </tr>
</table>

My solution was use readAsBinaryString() and btoa() on its result.

uploadFileToServer(event) {
    var file = event.srcElement.files[0];
    console.log(file);
    var reader = new FileReader();
    reader.readAsBinaryString(file);

    reader.onload = function() {
        console.log(btoa(reader.result));
    };
    reader.onerror = function() {
        console.log('there are some problems');
    };
}

Given

    volumes:
      - /dir/on/host:/var/www/html

if /dir/on/host doesn't exist, it is created on the host and the empty content is mounted in the container at /var/www/html. Whatever content you had before in /var/www/html inside the container is inaccessible, until you unmount the volume; the new mount is hiding the old content.

This is not a system font. this font is not supported in other systems. you can use font-face, convert font from this Site or from this

You can use the built-in javascript setInterval.

var ajax_call = function() {
  //your jQuery ajax code
};

var interval = 1000 * 60 * X; // where X is your every X minutes

setInterval(ajax_call, interval);

or if you are the more terse type ...

setInterval(function() {
  //your jQuery ajax code
}, 1000 * 60 * X); // where X is your every X minutes

Datasets implement IDisposable thorough MarshalByValueComponent, which implements IDisposable. Since datasets are managed there is no real benefit to calling dispose.

Many answer above are correct but same time convoluted with other aspects of authN/authZ. What actually resolves the exception in question is this line:

services.AddScheme<YourAuthenticationOptions, YourAuthenticationHandler>(YourAuthenticationSchemeName, options =>
    {
        options.YourProperty = yourValue;
    })

Ideally you shouldn't be splitting strings in T-SQL at all.

Barring that change, on older versions before SQL Server 2016, create a split function:

CREATE FUNCTION dbo.SplitStrings
(
    @List      nvarchar(max), 
    @Delimiter nvarchar(2)
)
RETURNS TABLE
WITH SCHEMABINDING
AS
  RETURN ( WITH x(x) AS
    (
      SELECT CONVERT(xml, N'<root><i>' 
        + REPLACE(@List, @Delimiter, N'</i><i>') 
        + N'</i></root>')
    )
    SELECT Item = LTRIM(RTRIM(i.i.value(N'.',N'nvarchar(max)')))
      FROM x CROSS APPLY x.nodes(N'//root/i') AS i(i)
  );
GO

Now you can say:

DECLARE @Values varchar(1000);

SET @Values = 'A, B, C';

SELECT blah
  FROM dbo.foo
  INNER JOIN dbo.SplitStrings(@Values, ',') AS s
    ON s.Item = foo.myField;

On SQL Server 2016 or above (or Azure SQL Database), it is much simpler and more efficient, however you do have to manually apply LTRIM() to take away any leading spaces:

DECLARE @Values varchar(1000) = 'A, B, C';

SELECT blah
  FROM dbo.foo
  INNER JOIN STRING_SPLIT(@Values, ',') AS s
    ON LTRIM(s.value) = foo.myField;

For Ubuntu and docker images:

/usr/share/nginx/html/

You can use $.map() (or even the .map() function that operates on a jQuery object) to get an array of checked values. The unary (+) operator will cast the string to a number

var arr = $.map($('input:checkbox:checked'), function(e,i) {
    return +e.value;
});

console.log(arr);

Here's an example

From What is Unicode:

Fundamentally, computers just deal with numbers. They store letters and other characters by assigning a number for each one.

......

Unicode provides a unique number for every character, no matter what the platform, no matter what the program, no matter what the language.

So when a computer represents a string, it finds characters stored in the computer of the string through their unique Unicode number and these figures are stored in memory. But you can't directly write the string to disk or transmit the string on network through their unique Unicode number because these figures are just simple decimal number. You should encode the string to byte string, such as UTF-8. UTF-8 is a character encoding capable of encoding all possible characters and it stores characters as bytes (it looks like this). So the encoded string can be used everywhere because UTF-8 is nearly supported everywhere. When you open a text file encoded in UTF-8 from other systems, your computer will decode it and display characters in it through their unique Unicode number. When a browser receive string data encoded UTF-8 from network, it will decode the data to string (assume the browser in UTF-8 encoding) and display the string.

In python3, you can transform string and byte string to each other:

>>> print('??'.encode('utf-8'))
b'\xe4\xb8\xad\xe6\x96\x87'
>>> print(b'\xe4\xb8\xad\xe6\x96\x87'.decode('utf-8'))
?? 

In a word, string is for displaying to humans to read on a computer and byte string is for storing to disk and data transmission.

To build a .tar.gz (aka .tgz) for an entire directory tree:

import tarfile
import os.path

def make_tarfile(output_filename, source_dir):
    with tarfile.open(output_filename, "w:gz") as tar:
        tar.add(source_dir, arcname=os.path.basename(source_dir))

This will create a gzipped tar archive containing a single top-level folder with the same name and contents as source_dir.

this is a generic method, you can use everywhere

const isBetween = (num1,num2,value) => value > num1 && value < num2 

If anybody needs light Swift extension to change UIView margins easily - you can use this

view.top = 16
view.right = self.width
view.bottom = self.height
self.height = view.bottom

function capitalize(s){
    return s.toLowerCase().replace( /\b./g, function(a){ return a.toUpperCase(); } );
};

capitalize('this IS THE wOrst string eVeR');

output: "This Is The Worst String Ever"

Update:

It appears this solution supersedes mine: https://stackoverflow.com/a/7592235/104380

It's possible to get this done using seaborn.lineplot() but it involves some additional work of converting numpy arrays to pandas dataframe. Here's a complete example:

# imports
import seaborn as sns
import numpy as np
import pandas as pd

# inputs
In [41]: num = np.array([1, 2, 3, 4, 5])
In [42]: sqr = np.array([1, 4, 9, 16, 25])

# convert to pandas dataframe
In [43]: d = {'num': num, 'sqr': sqr}
In [44]: pdnumsqr = pd.DataFrame(d)

# plot using lineplot
In [45]: sns.set(style='darkgrid')
In [46]: sns.lineplot(x='num', y='sqr', data=pdnumsqr)
Out[46]: <matplotlib.axes._subplots.AxesSubplot at 0x7f583c05d0b8>

And we get the following plot:

place something like this in your script file json-content.js

var mainjson = { your json data}

then call it from script tag

<script src="json-content.js"></script>

then you can use it in next script

<script>
console.log(mainjson)
</script>

Set JAVA_HOME in environment variable.

set JAVA_HOME to only JDK1.6.0_23 or whatever jdk folder you have. dont include bin folder in path.

If you're using Owl Carousel 2, then you should use the following:

$(".category-wrapper").owlCarousel({
     items : 4,
     loop  : true,
     margin : 30,
     nav    : true,
     smartSpeed :900,
     navText : ["<i class='fa fa-chevron-left'></i>","<i class='fa fa-chevron-right'></i>"]
   });

Excuse me when I answer your questions out-of-order, it makes it easier to understand this way.

When static variable is declared in a header file is its scope limited to .h file or across all units.

There is no such thing as a "header file scope". The header file gets included into source files. The translation unit is the source file including the text from the header files. Whatever you write in a header file gets copied into each including source file.

As such, a static variable declared in a header file is like a static variable in each individual source file.

Since declaring a variable static this way means internal linkage, every translation unit #includeing your header file gets its own, individual variable (which is not visible outside your translation unit). This is usually not what you want.

I would like to know what is the difference between static variables in a header file vs declared in a class.

In a class declaration, static means that all instances of the class share this member variable; i.e., you might have hundreds of objects of this type, but whenever one of these objects refers to the static (or "class") variable, it's the same value for all objects. You could think of it as a "class global".

Also generally static variable is initialized in .cpp file when declared in a class right ?

Yes, one (and only one) translation unit must initialize the class variable.

So that does mean static variable scope is limited to 2 compilation units ?

As I said:

• A header is not a compilation unit,
• static means completely different things depending on context.

Global static limits scope to the translation unit. Class static means global to all instances.

I hope this helps.

PS: Check the last paragraph of Chubsdad's answer, about how you shouldn't use static in C++ for indicating internal linkage, but anonymous namespaces. (Because he's right. ;-) )

You should check the EOF after reading from file.

fscanf_s                   // read from file
while(condition)           // check EOF
{
   fscanf_s               // read from file
}

Environment.GetSystemVariable("%SystemDrive%"); will provide the drive OS installed, and you can set filters to savedialog Obtain file path of C# save dialog box

php code to handle upload image and also create image from base64 encoded data

Just check my scripts it's working well:

  function handleFileSelect(evt) {
    var files = evt.target.files; // FileList object

    // Loop through the FileList and render image files as thumbnails.
    for (var i = 0, f; f = files[i]; i++) {

      // Only process image files.
      if (!f.type.match('image.*')) {
        continue;
      }

      // Closure to capture the file information.
      reader.onload = (function(theFile) {
        return function(e) {
          // Render thumbnail.
          var span = document.createElement('span');
          span.innerHTML = ['<img class="thumb" src="', e.target.result,
                            '" title="', escape(theFile.name), '"/>'].join('');
          document.getElementById('list').insertBefore(span, null);
        };
      })(f);

      // Read in the image file as a data URL.
      reader.readAsDataURL(f);
    }
  }

  document.getElementById('files').addEventListener('change', handleFileSelect, false);

#list img{
  width: auto;
  height: 100px;
  margin: 10px ;
}

Change the type to submit and give it a name (and remove the useless onclick and flat out the 90's style uppercased tags/attributes).

<input type="submit" name="foo" value="A" />
<input type="submit" name="foo" value="B" />
...

The value will be available by $_POST['foo'] (if the parent <form> has a method="post").

select * from sqlite_master where type = 'table' and tbl_name = 'TableName' and sql like '%ColumnName%'

Logic: sql column in sqlite_master contains table definition, so it certainly contains string with column name.

As you are searching for a sub-string, it has its obvious limitations. So I would suggest to use even more restrictive sub-string in ColumnName, for example something like this (subject to testing as '`' character is not always there):

select * from sqlite_master where type = 'table' and tbl_name = 'MyTable' and sql like '%`MyColumn` TEXT%'

Take the attribute

app:layout_behavior="@string/appbar_scrolling_view_behavior"

off the RecyclerView and put it on the FrameLayout that you are trying to show under the Toolbar.

I've found that one important thing the scrolling view behavior does is to layout the component below the toolbar. Because the FrameLayout has a descendant that will scroll (RecyclerView), the CoordinatorLayout will get those scrolling events for moving the Toolbar.

One other thing to be aware of: That layout behavior will cause the FrameLayout height to be sized as if the Toolbar is already scrolled, and with the Toolbar fully displayed the entire view is simply pushed down so that the bottom of the view is below the bottom of the CoordinatorLayout.

This was a surprise to me. I was expecting the view to be dynamically resized as the toolbar is scrolled up and down. So if you have a scrolling component with a fixed component at the bottom of your view, you won't see that bottom component until you have fully scrolled the Toolbar.

So when I wanted to anchor a button at the bottom of the UI, I worked around this by putting the button at the bottom of the CoordinatorLayout (android:layout_gravity="bottom") and adding a bottom margin equal to the button's height to the view beneath the toolbar.

I did basically the same thing that you did Adam, but with a slight modification to make sure I was appending to the head tag to get the job done. I simply created an include function (code below) to handle both script and css files.

This function also checks to make sure that the script or CSS file hasn't already been loaded dynamically. It does not check for hand coded values and there may have been a better way to do that, but it served the purpose.

function include( url, type ){
    // First make sure it hasn't been loaded by something else.
    if( Array.contains( includedFile, url ) )
        return;

    // Determine the MIME-type
    var jsExpr = new RegExp( "js$", "i" );
    var cssExpr = new RegExp( "css$", "i" );
    if( type == null )
        if( jsExpr.test( url ) )
            type = 'text/javascript';
        else if( cssExpr.test( url ) )
            type = 'text/css';

    // Create the appropriate element.
    var tag = null;
    switch( type ){
        case 'text/javascript' :
            tag = document.createElement( 'script' );
            tag.type = type;
            tag.src = url;
            break;
        case 'text/css' :
            tag = document.createElement( 'link' );
            tag.rel = 'stylesheet';
            tag.type = type;
            tag.href = url;
            break;
    }

    // Insert it to the <head> and the array to ensure it is not
    // loaded again.
    document.getElementsByTagName("head")[0].appendChild( tag );
    Array.add( includedFile, url );
}

If you are using JQuery, since the 1.6 you have to use the .prop() method :

$('select option:nth(1)').prop("selected","selected");

One thing not mentioned in answers is inline element can break among lines while inline-block can't (and obviously block)! So inline elements can be useful to style sentences of text and blocks inside them, but as they can't be padded you can use line-height instead.

try

System.IO.Path.GetFileNameWithoutExtension(path); 

demo

string fileName = @"C:\mydir\myfile.ext";
string path = @"C:\mydir\";
string result;

result = Path.GetFileNameWithoutExtension(fileName);
Console.WriteLine("GetFileNameWithoutExtension('{0}') returns '{1}'", 
    fileName, result);

result = Path.GetFileName(path);
Console.WriteLine("GetFileName('{0}') returns '{1}'", 
    path, result);

// This code produces output similar to the following:
//
// GetFileNameWithoutExtension('C:\mydir\myfile.ext') returns 'myfile'
// GetFileName('C:\mydir\') returns ''

Alright, no port 80, no Skype blame! My problem was indeed quite simple(&silly), I had an extra backslash (\) (on Windows) after the path I'd specified for the DocumentRoot directive, so I made a change like this and the problem is gone like a duck soup.

My index.php was in the path "D:\websites\dummy" and my httpd.conf was like this:

<VirtualHost 127.0.0.2:80>
ServerName dummy.local
DocumentRoot "D:\websites\dummy\" #mistake here
</VirtualHost>
<Directory "D:\websites\dummy\"> #mistake here
    Require all granted
</Directory>

So just change those two lines like this:

#first mistake fix:
DocumentRoot "D:\websites\dummy"
#second (similar) mistake fix:
<Directory "D:\websites\dummy">

...and everything's fine now. To prevent such mistakes in future, always copy the path of any folder you want to refer to instead of typing it yourself.

we are using below configuration to do something similar

    var gulp = require('gulp'),
    async = require("async"),
    less = require('gulp-less'),
    minifyCSS = require('gulp-minify-css'),
    uglify = require('gulp-uglify'),
    concat = require('gulp-concat'),
    gulpDS = require("./gulpDS"),
    del = require('del');

// CSS & Less
var jsarr = [gulpDS.jsbundle.mobile, gulpDS.jsbundle.desktop, gulpDS.jsbundle.common];
var cssarr = [gulpDS.cssbundle];

var generateJS = function() {

    jsarr.forEach(function(gulpDSObject) {
        async.map(Object.keys(gulpDSObject), function(key) {
            var val = gulpDSObject[key]
            execGulp(val, key);
        });

    })
}

var generateCSS = function() {
    cssarr.forEach(function(gulpDSObject) {
        async.map(Object.keys(gulpDSObject), function(key) {
            var val = gulpDSObject[key];
            execCSSGulp(val, key);
        })
    })
}

var execGulp = function(arrayOfItems, dest) {
    var destSplit = dest.split("/");
    var file = destSplit.pop();
    del.sync([dest])
    gulp.src(arrayOfItems)
        .pipe(concat(file))
        .pipe(uglify())
        .pipe(gulp.dest(destSplit.join("/")));
}

var execCSSGulp = function(arrayOfItems, dest) {
    var destSplit = dest.split("/");
    var file = destSplit.pop();
    del.sync([dest])
    gulp.src(arrayOfItems)
        .pipe(less())
        .pipe(concat(file))
        .pipe(minifyCSS())
        .pipe(gulp.dest(destSplit.join("/")));
}

gulp.task('css', generateCSS);
gulp.task('js', generateJS);

gulp.task('default', ['css', 'js']);

sample GulpDS file is below:

{

    jsbundle: {
        "mobile": {
            "public/javascripts/sample.min.js": ["public/javascripts/a.js", "public/javascripts/mobile/b.js"]
           },
        "desktop": {
            'public/javascripts/sample1.js': ["public/javascripts/c.js", "public/javascripts/d.js"]},
        "common": {
            'public/javascripts/responsive/sample2.js': ['public/javascripts/n.js']
           }
    },
    cssbundle: {
        "public/stylesheets/a.css": "public/stylesheets/less/a.less",
        }
}

The preferred solution as you've described it is a List of Pairs (i.e. List).

To accomplish this you would create a Pair class for use in your collection. This is a useful utility class to add to your code base.

The closest class in the Sun JDK providing functionality similar to a typical Pair class is AbstractMap.SimpleEntry. You could use this class rather than creating your own Pair class, though you would have to live with some awkward restrictions and I think most people would frown on this as not really the intended role of SimpleEntry. For example SimpleEntry has no "setKey()" method and no default constructor, so you may find it too limiting.

Bear in mind that Collections are designed to contain elements of a single type. Related utility interfaces such as Map are not actually Collections (i.e. Map does not implement the Collection interface). A Pair would not implement the Collection interface either but is obviously a useful class in building larger data structures.

I had the same problem, after some Windows 8.0 crash and update, on msys git 1.9. I didn't find any msys/git in my path, so I just added it in windows local-user envinroment settings. It worked without restarting.

Basically, similiar to RobertB, but I didn't have any git/msys in my path.

Btw:

1. I tried using rebase -b blablabla msys.dll, but had error "ReBaseImage (msys-1.0.dll) failed with last error = 6"

2. if you need this quickly and don't have time debugging, I noticed "Git Bash.vbs" in Git directory successfuly starts bash shell.
