findByInventoryIdIn(List<Long> inventoryIdList) should do the trick.

The HTTP request parameter format would be like so:

Yes ?id=1,2,3
No  ?id=1&id=2&id=3

The complete list of JPA repository keywords can be found in the current documentation listing. It shows that IsIn is equivalent – if you prefer the verb for readability – and that JPA also supports NotIn and IsNotIn.

Since these previous answers above, there is now a release of an Eclipse Plugin to assist with development using AngularJS:

https://marketplace.eclipse.org/content/angularjs-eclipse https://github.com/angelozerr/angularjs-eclipse/wiki/Installation---Update-Site (take a look around the other Wiki pages for information on features)

The release at the time of the answer is 0.1.0.

Please also checkout JSDT (http://www.eclipse.org/webtools/jsdt/) and also Eclipse VJET (http://eclipse.org/vjet/). The VJET project appears to be an attempt to provide better feature sets to the editor without being encumbered by the JSDT project (open source politics at play I guess).

This is in response to a number of comments as my reputation isn't high enough to comment directly.

You can specify the profile at runtime as long as the application context has not yet been loaded.

// Previous answers incorrectly used "spring.active.profiles" instead of
// "spring.profiles.active" (as noted in the comments).
// Use AbstractEnvironment.ACTIVE_PROFILES_PROPERTY_NAME to avoid this mistake.

System.setProperty(AbstractEnvironment.ACTIVE_PROFILES_PROPERTY_NAME, environment);
ApplicationContext applicationContext = new ClassPathXmlApplicationContext("/META-INF/spring/applicationContext.xml");

You can initialize the System property in a static initializer:

@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration(locations = "classpath:whereever/context.xml")
public class TestWarSpringContext {

    static {
        System.setProperty("myproperty", "foo");
    }

}

The static initializer code will be executed before the spring application context is initialized.

You have to workaround this via static application context accessor approach:

@Component
public class StaticContextAccessor {

    private static StaticContextAccessor instance;

    @Autowired
    private ApplicationContext applicationContext;

    @PostConstruct
    public void registerInstance() {
        instance = this;
    }

    public static <T> T getBean(Class<T> clazz) {
        return instance.applicationContext.getBean(clazz);
    }

}

Then you can access bean instances in a static manner.

public class Boo {

    public static void randomMethod() {
         StaticContextAccessor.getBean(Foo.class).doStuff();
    }

}

I got the same error in my microservice project.The property itself missed in my yml file.So I added property name and value that resolves my problem

Even better then @Tanjim Rahman answer you can using Spring Data JPA use the method T getOne(ID id)

Customer customerToUpdate = customerRepository.getOne(id);
customerToUpdate.setName(customerDto.getName);
customerRepository.save(customerToUpdate);

Is's better because getOne(ID id) gets you only a reference (proxy) object and does not fetch it from the DB. On this reference you can set what you want and on save() it will do just an SQL UPDATE statement like you expect it. In comparsion when you call find() like in @Tanjim Rahmans answer spring data JPA will do an SQL SELECT to physically fetch the entity from the DB, which you dont need, when you are just updating.

Spring MVC and Spring Boot are well described in other answers, and so without repeating that, let me jump straight to the specifics. Spring Boot and Spring MVC are not comparable or mutually exclusive. If you want to do web application development using Spring, you would use Spring MVC anyway. Your question then becomes whether to use Spring Boot or not.

For developing common Spring applications or starting to learn Spring, I think using Spring Boot would be recommended. It considerably eases the job, is production ready and is rapidly being widely adopted.

I have seen sometimes beginners asking this question because in STS (Spring Tool Suite) there are two wizards: one for creating a Spring Boot project, and another for creating a Spring MVC project. So, my recommendation would be to create a Spring Boot project and choose Web as a module in that.

For me, other answers didn't work. I had to go to open Files and do Invalidate caches and restart on Intellij. After that, everything worked fine again.

this is because of the object is not acceptable at jsp... use his

add this dependency or any other send converted json string to jsp...

for example add this in pom

<dependency>
        <groupId>com.google.code.gson</groupId>
        <artifactId>gson</artifactId>
        <version>2.6.2</version>
    </dependency>

and use code like that:

@RequestMapping(value="foobar.htm", method = RequestMethod.GET)
    public @ResponseBody String getShopInJSON() {
        Foo f = new Foo();
        f.setX(1);
        f.setY(2);
        f.setDescription("desc");
        return new Gson().toJson(f); //converted object into json string
    }//return converted json string

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.

This is the reason behind this error:

It will look for how the database that you are using generates ids. For MySql or HSQSL, there are increment fields that automatically increment. In Postgres or Oracle, they use sequence tables. Since you didn't specify a sequence table name, it will look for a sequence table named hibernate_sequence and use it for default. So you probably don't have such a sequence table in your database and now you get that error.

I believe its real use comes when you want to have more than one config files or you have xyz.xml file instead of applicationcontext.xml for eg

<context-param><param-name>contextConfigLocation</param-name> <param-value>/WEB-INF/training-service.xml, /WEB-INF/training-data.xml</param-value> </context-param>

Another approach to ContextLoaderListener is using ContextLoaderServlet like below

<servlet> <servlet-name>context</servlet-name> <servlet-class>org.springframework.web.context.ContextLoaderServlet</servlet-class> <load-on-startup>1</load-on-startup> </servlet>

I had the same problem unfortunately non of the solution here solved my problem as my problem was something in a different class.

I first checked that all dependencies are in place as suggested by @bekur then I checked the request/response that travels from clients to the server all headers was in place an properly set by Jquery. I then checked the RequestMappingHandlerAdapter MessageConverters and all 7 of them were in place, I really started to hate Spring ! I then updated to from Spring 4.0.6.RELEASE to 4.2.0.RELEASE I have got another response rather than the above. It was Request processing failed; nested exception is java.lang.IllegalArgumentException: No converter found for return value of type

Here is my controller method

  @RequestMapping(value = "/upload", method = RequestMethod.POST,produces = "application/json")
    public ResponseEntity<UploadPictureResult> pictureUpload(FirewalledRequest initialRequest) {

        DefaultMultipartHttpServletRequest request = (DefaultMultipartHttpServletRequest) initialRequest.getRequest();

        try {
            Iterator<String> iterator = request.getFileNames();

            while (iterator.hasNext()) {
                MultipartFile file = request.getFile(iterator.next());
                session.save(toImage(file));
            }
        } catch (Exception e) {
            return new ResponseEntity<UploadPictureResult>(new UploadPictureResult(),HttpStatus.INTERNAL_SERVER_ERROR);
        }
        return new ResponseEntity<UploadPictureResult>(new UploadPictureResult(), HttpStatus.OK);
    } 




    public class UploadPictureResult extends WebResponse{

    private List<Image> images;

    public void setImages(List<Image> images) {
        this.images = images;
    }
}






    public class WebResponse implements Serializable {


    protected String message;

    public WebResponse() {
    }

    public WebResponse(String message) {

        this.message = message;
    }


    public void setMessage(String message) {
        this.message = message;
    }
}

The solution was to make UploadPictureResult not to extend WebResponse

For some reason spring was not able to determine the how to convert UploadPictureReslt when it extended WebResponse

<context:annotation-config/> <!-- is used to activate the annotation for beans -->
<context:component-scan base-package="x.y.MyClass" /> <!-- is for the Spring IOC container to look for the beans in the base package. -->

The other important point to note is that context:component-scan implicitly calls the context:annotation-config to activate the annotations on beans. Well if you don't want context:component-scan to implicitly activate annotations for you, you can go on setting the annotation-config element of the context:component-scan to false.

To summarize:

<context:annotation-config/> <!-- activates the annotations --> 
<context:component-scan base-package="x.y.MyClass" /> <!-- activates the annotations + register the beans by looking inside the base-package -->

For most use cases, it's not correct to register MultipartFilter in web.xml because Spring MVC already does the work of processing your multipart request. It's even written in the filter's javadoc.

On the server side, define a multipartResolver bean in your app context:

@Bean
public CommonsMultipartResolver multipartResolver(){
    CommonsMultipartResolver commonsMultipartResolver = new CommonsMultipartResolver();
    commonsMultipartResolver.setDefaultEncoding("utf-8");
    commonsMultipartResolver.setMaxUploadSize(50000000);
    return commonsMultipartResolver;
}

On the client side, here's how to prepare the request for use with Spring RestTemplate API:

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

    LinkedMultiValueMap<String, String> pdfHeaderMap = new LinkedMultiValueMap<>();
    pdfHeaderMap.add("Content-disposition", "form-data; name=filex; filename=" + file.getOriginalFilename());
    pdfHeaderMap.add("Content-type", "application/pdf");
    HttpEntity<byte[]> doc = new HttpEntity<byte[]>(file.getBytes(), pdfHeaderMap);

    LinkedMultiValueMap<String, Object> multipartReqMap = new LinkedMultiValueMap<>();
    multipartReqMap.add("filex", doc);

    HttpEntity<LinkedMultiValueMap<String, Object>> reqEntity = new HttpEntity<>(multipartReqMap, headers);
    ResponseEntity<MyResponse> resE = restTemplate.exchange(uri, HttpMethod.POST, reqEntity, MyResponse.class);

The important thing is really to provide a Content-disposition header using the exact case, and adding name and filename specifiers, otherwise your part will be discarded by the multipart resolver.

Then, your controller method can handle the uploaded file with the following argument:

@RequestParam("filex") MultipartFile file

Hope this helps.

Following worked for me:
<context:property-placeholder location="file:src/resources/spring/AppController.properties"/>

Somehow "classpath:xxx" is not picking the file.

You can specify properties according profiles in one application.properties(yml) like here. Then mvn clean spring-boot:run -Dspring.profiles.active=dev should run it correct. It works for me

Since Spring 3.1 the id attribute is an xsd:string and permits the same range of characters as the name attribute.

The only difference between an id and a name is that a name can contain multiple aliases separated by a comma, semicolon or whitespace, whereas an id must be a single value.

From the Spring 3.2 documentation:

In XML-based configuration metadata, you use the id and/or name attributes to specify the bean identifier(s). The id attribute allows you to specify exactly one id. Conventionally these names are alphanumeric ('myBean', 'fooService', etc), but may special characters as well. If you want to introduce other aliases to the bean, you can also specify them in the name attribute, separated by a comma (,), semicolon (;), or white space. As a historical note, in versions prior to Spring 3.1, the id attribute was typed as an xsd:ID, which constrained possible characters. As of 3.1, it is now xsd:string. Note that bean id uniqueness is still enforced by the container, though no longer by XML parsers.

Do not use classpath. This may cause problems with different ClassLoaders (container vs. application). WEB-INF is always the better choice.

<context-param>
    <param-name>contextConfigLocation</param-name>
    <param-value>/WEB-INF/spring-config.xml</param-value>
</context-param>

and

<bean id="placeholderConfig" class="org.springframework.beans.factory.config.PropertyPlaceholderConfigurer">
     <property name="location">
         <value>/WEB-INF/social.properties</value>
     </property>
</bean>

For linux users: possible solution.

Build error due to "Failed to delete < any-file-or-folder >" will occur if there is by chance of only delete access provided to root user rather to normal-user.

Fix : type ll command to list file that cannot be deleted, if the file is given root access, change to normal user by :

sudo chown -R user-name:user-name filename

Later try for maven clean and build.

It doesn't matter is your app Boot or just raw Spring. There is just enough to inject org.springframework.core.env.Environment to your bean.

@Autowired
private Environment environment;
....

this.environment.getActiveProfiles();

The latest Spring + JPA versions solve this problem fundamentally. You can learn more how to use Spring and JPA togather in a separate thread

I know that due to this ugly anonymous inner class usage of TransactionTemplate doesn't look nice, but when for some reason we want to have a test method transactional IMHO it is the most flexible option.

In some cases (it depends on the application type) the best way to use transactions in Spring tests is a turned-off @Transactional on the test methods. Why? Because @Transactional may leads to many false-positive tests. You may look at this sample article to find out details. In such cases TransactionTemplate can be perfect for controlling transaction boundries when we want that control.

You need to add @Valid to each member variable, which was also an object that contained validation constraints.

Create 2 methods which handle the cases. You can instruct the @RequestMapping annotation to take into account certain parameters whilst mapping the request. That way you can nicely split this into 2 methods.

@RequestMapping (value="/submit/id/{id}", method=RequestMethod.GET, 
                 produces="text/xml", params={"logout"})
public String handleLogout(@PathVariable("id") String id, 
        @RequestParam("logout") String logout) { ... }

@RequestMapping (value="/submit/id/{id}", method=RequestMethod.GET, 
                 produces="text/xml", params={"name", "password"})
public String handleLogin(@PathVariable("id") String id, @RequestParam("name") 
        String username, @RequestParam("password") String password, 
        @ModelAttribute("submitModel") SubmitModel model, BindingResult errors) 
        throws LoginException {...}

Solution for people using Gradle

Add plugin to build.gradle

apply plugin: 'war'

Add provided dependency to tomcat

dependencies {

    providedRuntime 'org.springframework.boot:spring-boot-starter-tomcat'
}

Could not commit JPA transaction: Transaction marked as rollbackOnly

This exception occurs when you invoke nested methods/services also marked as @Transactional. JB Nizet explained the mechanism in detail. I'd like to add some scenarios when it happens as well as some ways to avoid it.

Suppose we have two Spring services: Service1 and Service2. From our program we call Service1.method1() which in turn calls Service2.method2():

class Service1 {
    @Transactional
    public void method1() {
        try {
            ...
            service2.method2();
            ...
        } catch (Exception e) {
            ...
        }
    }
}

class Service2 {
    @Transactional
    public void method2() {
        ...
        throw new SomeException();
        ...
    }
}

SomeException is unchecked (extends RuntimeException) unless stated otherwise.

Scenarios:

1. Transaction marked for rollback by exception thrown out of method2. This is our default case explained by JB Nizet.

2. Annotating method2 as @Transactional(readOnly = true) still marks transaction for rollback (exception thrown when exiting from method1).

3. Annotating both method1 and method2 as @Transactional(readOnly = true) still marks transaction for rollback (exception thrown when exiting from method1).

4. Annotating method2 with @Transactional(noRollbackFor = SomeException) prevents marking transaction for rollback (no exception thrown when exiting from method1).

5. Suppose method2 belongs to Service1. Invoking it from method1 does not go through Spring's proxy, i.e. Spring is unaware of SomeException thrown out of method2. Transaction is not marked for rollback in this case.

6. Suppose method2 is not annotated with @Transactional. Invoking it from method1 does go through Spring's proxy, but Spring pays no attention to exceptions thrown. Transaction is not marked for rollback in this case.

7. Annotating method2 with @Transactional(propagation = Propagation.REQUIRES_NEW) makes method2 start new transaction. That second transaction is marked for rollback upon exit from method2 but original transaction is unaffected in this case (no exception thrown when exiting from method1).

8. In case SomeException is checked (does not extend RuntimeException), Spring by default does not mark transaction for rollback when intercepting checked exceptions (no exception thrown when exiting from method1).

See all scenarios tested in this gist.

I am providing a code snippet of RestTemplate GET method with path param example

public ResponseEntity<String> getName(int id) {
    final String url = "http://localhost:8080/springrestexample/employee/name?id={id}";
    Map<String, String> params = new HashMap<String, String>();
    params.put("id", id);
    HttpHeaders headers = new HttpHeaders();
    headers.setContentType(MediaType.APPLICATION_JSON);
    HttpEntity request = new HttpEntity(headers);
    ResponseEntity<String> response = restTemplate.exchange(url, HttpMethod.GET, String.class, params);
    return response;
}

Mike Nereson has this to say on his blog at:

http://blog.codehangover.com/load-multiple-contexts-into-spring/

There are a couple of ways to do this.

1. web.xml contextConfigLocation

Your first option is to load them all into your Web application context via the ContextConfigLocation element. You’re already going to have your primary applicationContext here, assuming you’re writing a web application. All you need to do is put some white space between the declaration of the next context.

  <context-param>
      <param-name> contextConfigLocation </param-name>
      <param-value>
          applicationContext1.xml
          applicationContext2.xml
      </param-value>
  </context-param>

  <listener>
      <listener-class>
          org.springframework.web.context.ContextLoaderListener
      </listener-class>
  </listener>

The above uses carriage returns. Alternatively, yo could just put in a space.

  <context-param>
      <param-name> contextConfigLocation </param-name>
      <param-value> applicationContext1.xml applicationContext2.xml </param-value>
  </context-param>

  <listener>
      <listener-class> org.springframework.web.context.ContextLoaderListener </listener-class>
  </listener>

2. applicationContext.xml import resource

Your other option is to just add your primary applicationContext.xml to the web.xml and then use import statements in that primary context.

In applicationContext.xml you might have…

  <!-- hibernate configuration and mappings -->
  <import resource="applicationContext-hibernate.xml"/>

  <!-- ldap -->
  <import resource="applicationContext-ldap.xml"/>

  <!-- aspects -->
  <import resource="applicationContext-aspects.xml"/>

Which strategy should you use?

1. I always prefer to load up via web.xml.

Because , this allows me to keep all contexts isolated from each other. With tests, we can load just the contexts that we need to run those tests. This makes development more modular too as components stay loosely coupled, so that in the future I can extract a package or vertical layer and move it to its own module.

2. If you are loading contexts into a non-web application, I would use the import resource.

You can set RequestParam, using generic class Integer instead of int, it will resolve your issue.

   @RequestParam(value= "i", defaultValue = "20") Integer i

The answer of Shyam was right. I already faced with this issue before. It's not a problem, it's a SPRING feature. "Transaction rolled back because it has been marked as rollback-only" is acceptable.

Conclusion

• USE REQUIRES_NEW if you want to commit what did you do before exception (Local commit)
• USE REQUIRED if you want to commit only when all processes are done (Global commit) And you just need to ignore "Transaction rolled back because it has been marked as rollback-only" exception. But you need to try-catch out side the caller processNextRegistrationMessage() to have a meaning log.

Let's me explain more detail:

Question: How many Transaction we have? Answer: Only one

Because you config the PROPAGATION is PROPAGATION_REQUIRED so that the @Transaction persist() is using the same transaction with the caller-processNextRegistrationMessage(). Actually, when we get an exception, the Spring will set rollBackOnly for the TransactionManager so the Spring will rollback just only one Transaction.

Question: But we have a try-catch outside (), why does it happen this exception? Answer Because of unique Transaction

1. When persist() method has an exception

2. Go to the catch outside

   Spring will set the rollBackOnly to true -> it determine we must 
   rollback the caller (processNextRegistrationMessage) also.
   

3. The persist() will rollback itself first.

4. Throw an UnexpectedRollbackException to inform that, we need to rollback the caller also.
5. The try-catch in run() will catch UnexpectedRollbackException and print the stack trace

Question: Why we change PROPAGATION to REQUIRES_NEW, it works?

Answer: Because now the processNextRegistrationMessage() and persist() are in the different transaction so that they only rollback their transaction.

Thanks

You can pass input as ["apple","orange"]if you want to leave the method as it is.

It worked for me with a similar method signature.

While the other answers are correct it certainly is not the "Spring way" to use the HttpServletRequest object directly. The answer is actually quite simple and what you would expect if you're familiar with Spring MVC.

@RequestMapping(value = {"/search/", "/search"}, method = RequestMethod.GET)
public String search(
@RequestParam Map<String,String> allRequestParams, ModelMap model) {
   return "viewName";
}

Turns out, when the table name is different than the model name, you have to change the annotations to:

@Entity
@Table(name = "table_name")
class WhateverNameYouWant {
    ...

Instead of simply using the @Entity annotation.

What was weird for me, is that the class it was trying to convert to didn't exist. This worked for me.

Copied from the stacktrace:

BeanInstantiationException: Could not instantiate bean class [com.gestEtu.project.model.dao.CompteDAOHib]: No default constructor found; nested exception is java.lang.NoSuchMethodException: com.gestEtu.project.model.dao.CompteDAOHib.<init>()

By default, Spring will try to instantiate beans by calling a default (no-arg) constructor. The problem in your case is that the implementation of the CompteDAOHib has a constructor with a SessionFactory argument. By adding the @Autowired annotation to a constructor, Spring will attempt to find a bean of matching type, SessionFactory in your case, and provide it as a constructor argument, e.g.

@Autowired
public CompteDAOHib(SessionFactory sessionFactory) {
    // ...
}

Make sure that your IntelliJ Idea (IDE) is aware of all the necessary spring configurations that your module is being inspected against.

You can check this under

File > Project Structure > Modules > [your project name in the right panel] > Spring

Sometimes, we need to explicitly tell the IDE that the spring configuration is coming from a dependency (a jar present in your project classpath)

I had the dependencies as specified @Greg post. I still faced the issue and could be able to resolve it by adding following additional jackson dependency:

<dependency>
    <groupId>com.fasterxml.jackson.dataformat</groupId>
    <artifactId>jackson-dataformat-xml</artifactId>
    <version>2.7.4</version>
</dependency>

The solution can be found here https://github.com/spring-projects/spring-framework/issues/22734

you can create two separate post request mappings. For example.

@PostMapping(path = "/test", consumes = "application/json")
public String test(@RequestBody User user) {
  return user.toString();
}

@PostMapping(path = "/test", consumes = "application/x-www-form-urlencoded")
public String test(User user) {
  return user.toString();
}

Right-Click on your project -> Properties -> Deployment Assembly.

On the Left-hand panel Click 'Add' and add the 'Project and External Dependencies'.

'Project and External Dependencies' will have all the spring related jars deployed along with your application

Have you tried rewording your query like this?

@Query("SELECT DISTINCT p.name FROM People p WHERE p.name NOT IN ?1")
List<String> findNonReferencedNames(List<String> names);

Note, I'm assuming your entity class is named People, and not people.

Best way to handle such error-"Use Annotation". spring.xml-<context:component-scan base-package=com.SpringCollection.SpringCollection"/>

add annotation in that class for which you want to use Bean ID(i am using class "First")-

@Component

public class First {

Changes In Main Class**-

ApplicationContext context = new AnnotationConfigApplicationContext(First.class); use this.

For me below worked in MS SQL

 @Query(value="SELECT * FROM ABC r where r.type in :type  ORDER BY RAND() \n-- #pageable\n ",nativeQuery = true)
List<ABC> findByBinUseFAndRgtnType(@Param("type") List<Byte>type,Pageable pageable);

I know, I am tooooo late to post an answer, but hoping that it might help someone. Plus, I just solved this issue I had with my tests. This is what I had in my test:

My test class

@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration(locations = { "path-to-context" })
@Transactional
public class MyIntegrationTest 

Context xml

<bean id="dataSource" class="org.apache.commons.dbcp.BasicDataSource">
   <property name="driverClassName" value="${jdbc.driverClassName}" />
   <property name="url" value="${jdbc.url}" />
   <property name="username" value="${jdbc.username}" />
   <property name="password" value="${jdbc.password}" />
</bean>

I still had the problem that, the database was not being cleaned up automatically.

Issue was resolved when I added following property to BasicDataSource

<property name="defaultAutoCommit" value="false" />

Hope it helps.

Also if you want to return 404 status from your controller all you need is to do this

@RequestMapping(value = "/somthing", method = RequestMethod.POST)
@ResponseBody
public HttpStatus doSomthing(@RequestBody String employeeId) {
    try{
  return HttpStatus.OK;
    } 
    catch(Exception ex){ 
  return HttpStatus.NOT_FOUND;
    }
}

By doing this you will receive a 404 error in case when you want to return a 404 from your controller.

Just put one more entry in your spring xml file i.e.mvc-dispatcher-servlet.xml

<mvc:view-controller path="/" view-name="index"/>

After putting this to your xml put your default view or jsp file in your custom JSP folder as you have mentioned in mvc-dispatcher-servlet.xml file.

change index with your jsp name.

Spring boot + spring mvn

with issue

@PostMapping("/addDonation")
public String addDonation(@RequestBody DonatorDTO donatorDTO) {

with solution

@RequestMapping(value = "/addDonation", method = RequestMethod.POST)
@ResponseBody
public GenericResponse addDonation(final DonatorDTO donatorDTO, final HttpServletRequest request){

@Resource annotation on field level also could be used to declare look up at runtime

so I had same problem here. Found out that my domain instance was getting detached from the hibernate session. I used isAttached() to check and attached the domain using d.attach()

I know this is old, but I was having trouble too. For Spring 3 using Maven and Eclipse, I needed to put the log4j.xml in src/test/resources for the Unit test to log properly. Placing in in the root of the test did not work for me. Hopefully this helps others.

Your json contains an array, but you're trying to parse it as an object. This error occurs because objects must start with {.

You have 2 options:

1. You can get rid of the ShopContainer class and use Shop[] instead

   ShopContainer response  = restTemplate.getForObject(
       url, ShopContainer.class);
   

   replace with

   Shop[] response  = restTemplate.getForObject(url, Shop[].class);
   

   and then make your desired object from it.

2. You can change your server to return an object instead of a list

   return mapper.writerWithDefaultPrettyPrinter().writeValueAsString(list);
   

   replace with

   return mapper.writerWithDefaultPrettyPrinter().writeValueAsString(
       new ShopContainer(list));
   

There is also some more detail on the use of <mvc:annotation-driven /> in the Spring docs. In a nutshell, <mvc:annotation-driven /> gives you greater control over the inner workings of Spring MVC. You don't need to use it unless you need one or more of the features outlined in the aforementioned section of the docs.

Also, there are other "annotation-driven" tags available to provide additional functionality in other Spring modules. For example, <transaction:annotation-driven /> enables the use of the @Transaction annotation, <task:annotation-driven /> is required for @Scheduled et al...

Below is one of the way by which you can achieve that, may not be an ideal way to do.

Have one method accepting both types of request, then check what type of request you received, is it of type "GET" or "POST", once you come to know that, do respective actions and the call one method which does common task for both request Methods ie GET and POST.

@RequestMapping(value = "/books")
public ModelAndView listBooks(HttpServletRequest request){
     //handle both get and post request here
     // first check request type and do respective actions needed for get and post.

    if(GET REQUEST){

     //WORK RELATED TO GET

    }else if(POST REQUEST){

      //WORK RELATED TO POST

    }

    commonMethod(param1, param2....);
}

If you're using latest spring boot (with jdbc starter and Hikari) you'll run into: java.lang.IllegalArgumentException: jdbcUrl is required with driverClassName. To solve this:

1. In your application.properties:

datasource.oracle.url=youroracleurl

2. In your application define as bean (@Primary is mandatory!):

@Bean
@Primary
@ConfigurationProperties("datasource.oracle")
public DataSourceProperties getDatasourceProperties() {
    return new DataSourceProperties();
}

@Bean
@ConfigurationProperties("datasource.oracle")
public DataSource getDatasource() {
    return getDatasourceProperties().initializeDataSourceBuilder()
           .username("username")
           .password("password")
           .build();
}

You can still continue to use the same View resolver but set the suffix to empty.

<bean id="viewResolver" class="org.springframework.web.servlet.view.InternalResourceViewResolver" 
    p:prefix="/WEB-INF/jsp/" p:suffix="" />

Now your code can choose to return either index.html or index.jsp as shown in below sample -

@RequestMapping(value="jsp", method = RequestMethod.GET )
public String startJsp(){
    return "/test.jsp";
}

@RequestMapping(value="html", method = RequestMethod.GET )
public String startHtml(){
    return "/test.html";
}   

This error basically happens when the specific port is not free. So there are two solutions, you can free that port by killing or closing the service which is using it or you can run your application (tomcat) on a different port.

Solution 1: Free the port

On a Linux machine you can find the process-id of port's consumer and then kill it. Use the following command (it is assume that the default port is 8080)

netstat -pnltu | grep -i "8080"

The output of the above-mentioned command would be something like:

tcp6   0  0 :::8080    :::*      LISTEN      20674/java 

Then you can easily kill the process with its processid:

kill 20674

On a windows machine to find a processid use netstat -ano -p tcp |find "8080". To kill the process use taskkill /F /PID 1234 (instead of 1234 enter the founded processid).

Solution 2: Change the default port

In the development process developers use the port 8080 that you can change it easily. You need to specify your desired port number in the application.properties file of your project (/src/main/resources/application.properties) by using the following specification:

server.port=8081

You can also set an alternative port number while executing the .jar file

- java -jar spring-boot-application.jar --server.port=8081

Please notice that sometimes (not necessarily) you have to change other ports too like:

management.port=
tomcat.jvmroute=
tomcat.ajp.port=
tomcat.ajp.redirectPort=
etc...

This is a maven specific problem I think. Maven does not copy the files form /src/main/resources to the target-test folder. You will have to do this yourself by configuring the resources plugin, if you absolutely want to go this way.

An easier way is to instead put a test specific context definition in the /src/test/resources directory and load via:

@ContextConfiguration(locations = { "classpath:mycontext.xml" })

1) Go to your project and find ".settings" directory this one
2) Open file xml named:
org.eclipse.wst.common.project.facet.core.xml
3)

<?xml version="1.0" encoding="UTF-8"?>
    <faceted-project>
    <fixed facet="wst.jsdt.web"/>
    <installed facet="java" version="1.5"/>
    <installed facet="jst.web" version="2.3"/>
    <installed facet="wst.jsdt.web" version="1.0"/>
 </faceted-project>

Change jst.web version to 3.0 and java version to 1.7 or 1.8 (base on your current using jdk version)

4) Change your web.xml file under WEB-INF directory , please refer to this article:
https://www.mkyong.com/web-development/the-web-xml-deployment-descriptor-examples/
5) Go to pom.xml file and paste these lines:

<build>
    <finalName>YOUR_PROJECT_NAME</finalName>
    <plugins>
        <plugin>
            <groupId>org.apache.maven.plugins</groupId>
            <artifactId>maven-compiler-plugin</artifactId>
            <version>3.3</version>
            <configuration>
                <source>1.8</source> THIS IS YOUR USING JDK's VERSION
                <target>1.8</target> SAME AS ABOVE
            </configuration>
        </plugin>
    </plugins>
</build>  

The following signature will do:

List<Email> findByEmailIdInAndPincodeIn(List<String> emails, List<String> pinCodes);

Spring Data JPA supports a large number of keywords to build a query. IN and AND are among them.

Try this code:

@RequestMapping(value = "/validate", method = RequestMethod.GET, produces = "application/json")
public ResponseEntity<ErrorBean> validateUser(@QueryParam("jsonInput") final String jsonInput) {
    int numberHTTPDesired = 400;
    ErrorBean responseBean = new ErrorBean();
    responseBean.setError("ERROR");
    responseBean.setMensaje("Error in validation!");

    return new ResponseEntity<ErrorBean>(responseBean, HttpStatus.valueOf(numberHTTPDesired));
}

Spring way:
private @Value("${propertyName}") String propertyField;

is a new way to inject the value using Spring's "PropertyPlaceholderConfigurer" class. Another way is to call

java.util.Properties props = System.getProperties().getProperty("propertyName");

Note: For @Value, you can not use static propertyField, it should be non-static only, otherwise it returns null. To fix it a non static setter is created for the static field and @Value is applied above that setter.

@EnableConfigurationProperties needs to be there (you also can annotate your test class), the application-localtest.yml from test/resources will be loaded. A sample with jUnit5

@ExtendWith(SpringExtension.class)
@EnableConfigurationProperties
@ContextConfiguration(classes = {YourClasses}, initializers = ConfigFileApplicationContextInitializer.class)
@ActiveProfiles(profiles = "localtest")
class TestActiveProfile {

    @Test
    void testActiveProfile(){

    }
}

From Spring Boot 1.4, you can use the new @SpringBootTest annotation to achieve this more easily (and to simplify your integration test setup in general) by bootstrapping your integration tests using Spring Boot support.

Details on the Spring Blog.

As far as I can tell, this means you get all the benefits of Spring Boot's externalized config goodness just like in your production code, including automatically picking up YAML config from the classpath.

By default, this annotation will

... first attempt to load @Configuration from any inner-classes, and if that fails, it will search for your primary @SpringBootApplication class.

but you can specify other configuration classes if required.

For this particular case, you can combine @SpringBootTest with @ActiveProfiles( "test" ) and Spring will pick up your YAML config, provided it follows the normal Boot naming standards (i.e. application-test.yml).

@RunWith( SpringRunner.class )
@SpringBootTest
@ActiveProfiles( "test" )
public class SpringBootITest {

    @Value("${db.username}")
    private String username;

    @Autowired
    private MyBean myBean;

    ...

}

Note: SpringRunner.class is the new name for SpringJUnit4ClassRunner.class

I found a similar post @Autowired bean is null when referenced in the constructor of another bean .

The root cause of the error can be explained in the Spring reference doc (Autowired) , as follow:

Autowired Fields

Fields are injected right after construction of a bean, before any config methods are invoked.

But the real reason behind this statement in Spring doc is the Lifecycle of Bean in Spring. This is part of Spring's design philosophy.

This is Spring Bean Lifecycle Overview: Bean needs to be initialized first before it can be injected with properties such as field. This is how beans are designed, so this is the real reason.

I hope this answer is helpful to you!

The NoSuchMethodError javadoc says this:

Thrown if an application tries to call a specified method of a class (either static or instance), and that class no longer has a definition of that method.

Normally, this error is caught by the compiler; this error can only occur at run time if the definition of a class has incompatibly changed.

In your case, this Error is a strong indication that your webapp is using the wrong version of the JAR defining the org.objectweb.asm.* classes.

Another way is using a ResourceBundle. Basically you get the bundle using its name without the '.properties'

private static final ResourceBundle resource = ResourceBundle.getBundle("config");

And you recover any value using this:

private final String prop = resource.getString("propName");

Make sure that Spring version and xsd version both are same.In my case I am using Spring 4.1.1 so my all xsd should be version *-4.1.xsd

If you're using Spring Boot, the simplest way to disable the Spring Security default headers is to use security.headers.* properties. In particular, if you want to disable the X-Frame-Options default header, just add the following to your application.properties:

security.headers.frame=false

There is also security.headers.cache, security.headers.content-type, security.headers.hsts and security.headers.xss properties that you can use. For more information, take a look at SecurityProperties.

I've searched a lot and the best way I've found so far is on this article:

Class to serialize

package net.sghill.example;

import net.sghill.example.UserDeserializer
import net.sghill.example.UserSerializer
import org.codehaus.jackson.map.annotate.JsonDeserialize;
import org.codehaus.jackson.map.annotate.JsonSerialize;

@JsonDeserialize(using = UserDeserializer.class)
public class User {
    private ObjectId id;
    private String   username;
    private String   password;

    public User(ObjectId id, String username, String password) {
        this.id = id;
        this.username = username;
        this.password = password;
    }

    public ObjectId getId()       { return id; }
    public String   getUsername() { return username; }
    public String   getPassword() { return password; }
}

Deserializer class

package net.sghill.example;

import net.sghill.example.User;
import org.codehaus.jackson.JsonNode;
import org.codehaus.jackson.JsonParser;
import org.codehaus.jackson.ObjectCodec;
import org.codehaus.jackson.map.DeserializationContext;
import org.codehaus.jackson.map.JsonDeserializer;

import java.io.IOException;

public class UserDeserializer extends JsonDeserializer<User> {

    @Override
    public User deserialize(JsonParser jsonParser, DeserializationContext deserializationContext) throws IOException {
        ObjectCodec oc = jsonParser.getCodec();
        JsonNode node = oc.readTree(jsonParser);
        return new User(null, node.get("username").getTextValue(), node.get("password").getTextValue());
    }
}

Edit: Alternatively you can look at this article which uses new versions of com.fasterxml.jackson.databind.JsonDeserializer.

You can do the same like this:

@Override
public FaqQuestions getFaqQuestionById(Long questionId) {
    session = sessionFactory.openSession();
    tx = session.beginTransaction();
    FaqQuestions faqQuestions = null;
    try {
        faqQuestions = (FaqQuestions) session.get(FaqQuestions.class,
                questionId);
        Hibernate.initialize(faqQuestions.getFaqAnswers());

        tx.commit();
        faqQuestions.getFaqAnswers().size();
    } finally {
        session.close();
    }
    return faqQuestions;
}

Just use faqQuestions.getFaqAnswers().size()nin your controller and you will get the size if lazily intialised list, without fetching the list itself.

It also works if you change the content type

    <form method="POST"
    action="http://localhost:8080/cms/customer/create_customer"
    id="frmRegister" name="frmRegister"
    enctype="application/x-www-form-urlencoded">

In the controller also add the header value as follows:

    @RequestMapping(value = "/create_customer", method = RequestMethod.POST, headers = "Content-Type=application/x-www-form-urlencoded")

You'll have to have a ContextLoaderListener in your web.xml - It loads your configuration files.

<listener>
    <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
</listener>

You need to understand the difference between Web application context and root application context .

In the web MVC framework, each DispatcherServlet has its own WebApplicationContext, which inherits all the beans already defined in the root WebApplicationContext. These inherited beans defined can be overridden in the servlet-specific scope, and new scope-specific beans can be defined local to a given servlet instance.

The dispatcher servlet's application context is a web application context which is only applicable for the Web classes . You cannot use these for your middle tier layers . These need a global app context using ContextLoaderListener .

Read the spring reference here for spring mvc .

One of the coolest benefits of using something like Spring is that you don't have to wire your objects together. Zeus's head splits open and your classes appear, fully formed with all of their dependencies created and wired-in, as needed. It's magical and fantastic.

The more you say ClassINeed classINeed = (ClassINeed)ApplicationContext.getBean("classINeed");, the less magic you're getting. Less code is almost always better. If your class really needed a ClassINeed bean, why didn't you just wire it in?

That said, something obviously needs to create the first object. There's nothing wrong with your main method acquiring a bean or two via getBean(), but you should avoid it because whenever you're using it, you're not really using all of the magic of Spring.

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

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

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

HttpEntity entity = new HttpEntity(headers);

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

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

This question is similar to this question.

Check if you missed @Service annotation in your service class, that was the case for me.

Here is my solution. May help someone;

It returns InputStream, but i assume you can read from it too.

InputStream is = Thread.currentThread().getContextClassLoader().getResourceAsStream("jsonschema.json");

Seems like you just forgot the comma to separate the classes. So based on your configuration the following will work:

spring.autoconfigure.exclude=org.springframework.boot.autoconfigure.orm.jpa.HibernateJpaAutoConfiguration,\
    org.springframework.boot.autoconfigure.jdbc.DataSourceAutoConfiguration,\
    org.springframework.boot.autoconfigure.jdbc.DataSourceTransactionManagerAutoConfiguration,\
    org.springframework.boot.autoconfigure.data.web.SpringDataWebAutoConfiguration

Alternatively you could also define it as follow:

spring.autoconfigure.exclude[0]=org.springframework.boot.autoconfigure.orm.jpa.HibernateJpaAutoConfiguration
spring.autoconfigure.exclude[1]=org.springframework.boot.autoconfigure.jdbc.DataSourceAutoConfiguration
spring.autoconfigure.exclude[2]=org.springframework.boot.autoconfigure.jdbc.DataSourceTransactionManagerAutoConfiguration
spring.autoconfigure.exclude[3]=org.springframework.boot.autoconfigure.data.web.SpringDataWebAutoConfiguration

Solution without Mocking class, Java9+ and Spring only.

FileItem fileItem = new DiskFileItemFactory().createItem("file",
    Files.probeContentType(file.toPath()), false, file.getName());

try (InputStream in = new FileInputStream(file); OutputStream out = fileItem.getOutputStream()) {
    in.transferTo(out);
} catch (Exception e) {
    throw new IllegalArgumentException("Invalid file: " + e, e);
}

CommonsMultipartFile multipartFile = new CommonsMultipartFile(fileItem);

You can also ask the user for the credentials and set them dynamically once the server starts (very effective when you need to publish the solution on a customer environment):

@EnableWebSecurity
public class SecurityConfig {

    private static final Logger log = LogManager.getLogger();

    @Autowired
    public void configureGlobal(AuthenticationManagerBuilder auth) throws Exception {
        log.info("Setting in-memory security using the user input...");

        Scanner scanner = new Scanner(System.in);
        String inputUser = null;
        String inputPassword = null;
        System.out.println("\nPlease set the admin credentials for this web application");
        while (true) {
            System.out.print("user: ");
            inputUser = scanner.nextLine();
            System.out.print("password: ");
            inputPassword = scanner.nextLine();
            System.out.print("confirm password: ");
            String inputPasswordConfirm = scanner.nextLine();

            if (inputUser.isEmpty()) {
                System.out.println("Error: user must be set - please try again");
            } else if (inputPassword.isEmpty()) {
                System.out.println("Error: password must be set - please try again");
            } else if (!inputPassword.equals(inputPasswordConfirm)) {
                System.out.println("Error: password and password confirm do not match - please try again");
            } else {
                log.info("Setting the in-memory security using the provided credentials...");
                break;
            }
            System.out.println("");
        }
        scanner.close();

        if (inputUser != null && inputPassword != null) {
             auth.inMemoryAuthentication()
                .withUser(inputUser)
                .password(inputPassword)
                .roles("USER");
        }
    }
}

(May 2018) An update - this will work on spring boot 2.x:

}

There are two ways to achieve this:

final PageRequest page1 = new PageRequest(
  0, 20, Direction.ASC, "lastName", "salary"
);

final PageRequest page2 = new PageRequest(
  0, 20, new Sort(
    new Order(Direction.ASC, "lastName"), 
    new Order(Direction.DESC, "salary")
  )
);

dao.findAll(page1);

As you can see the second form is more flexible as it allows to define different direction for every property (lastName ASC, salary DESC).

According to documentation it is:

spring.jpa.show-sql=true # Enable logging of SQL statements.

For Jpa based application: base package scan @EnableJpaRepositories(basePackages = "repository") You can try it once!!!

I believe this will solve the issue

var z = '[{"name":"1","age":"2"},{"name":"1","age":"3"}]';
z = JSON.stringify(JSON.parse(z));
$.ajax({

    data: z,
    type: "POST",
    dataType:"json",
    contentType:'application/json'               
});

You can Autowire the ApplicationContext, either as a field

@Autowired
private ApplicationContext context;

or a method

@Autowired
public void context(ApplicationContext context) { this.context = context; }

Finally use

context.getBean(SomeClass.class)

As documentation says:

Raised when the part of a "multipart/form-data" request identified by its name cannot be found.

This may be because the request is not a multipart/form-data either because the part is not present in the request, or because the web application is not configured correctly for processing multipart requests -- e.g. no MultipartResolver.

disable the transactionmanager in your Bean.xml

<tx:annotation-driven proxy-target-class="true" transaction-manager="transactionManager"/>
    <bean id="transactionManager"
        class="org.springframework.jdbc.datasource.DataSourceTransactionManager">
        <property name="dataSource" ref="dataSource"></property>
    </bean>

comment out these lines, and you'll see the exception causing the rollback ;)

While working with Spring Boot application, it is difficult to get the classpath resources using resource.getFile() when it is deployed as JAR as I faced the same issue. This scan be resolved using Stream which will find out all the resources which are placed anywhere in classpath.

Below is the code snippet for the same -

ClassPathResource classPathResource = new ClassPathResource("fileName");
InputStream inputStream = classPathResource.getInputStream();
content = IOUtils.toString(inputStream);

Put your style.css directly into the webapp/css folder, not into the WEB-INF folder.

Then add the following code into your spring-dispatcher-servlet.xml

<mvc:resources mapping="/css/**" location="/css/" />

and then add following code into your jsp page

<link rel="stylesheet" type="text/css" href="css/style.css"/>

I hope it will work.

This is a typical startup failure due to the embedded servlet container’s port being in use.

Your embedded tomcat container failed to start because Port 8080 was already in use.

Just Identify and stop the process that's listening on port 8080 or configure (in you application.properties file )this application to listen on another port.

Since this questions seems to still get quite a lot of views, it might be useful to note that for Spring 4+ it's easiest to start using Spring Boot and the Spring Boot starter POMs.

Using Spring Boot there's less dependencies to manage (and thus fewer conflicts), and setting up a working, well integrated Spring Context is a whole lot easier. I highly recommend it.

You have to update your

scanBasePackages = { "com.exm.java" }

to add the path to your service (after annotating it with @service )

There are many way to get application context in Spring application. Those are given bellow:

1. Via ApplicationContextAware:

   import org.springframework.beans.BeansException;
   import org.springframework.context.ApplicationContext;
   import org.springframework.context.ApplicationContextAware;
   
   public class AppContextProvider implements ApplicationContextAware {
   
   private ApplicationContext applicationContext;
   
   @Override
   public void setApplicationContext(ApplicationContext applicationContext) throws BeansException {
       this.applicationContext = applicationContext;
   }
   }
   

Here setApplicationContext(ApplicationContext applicationContext) method you will get the applicationContext

2. Via Autowired:

   @Autowired
   private ApplicationContext applicationContext;
   

Here @Autowired keyword will provide the applicationContext.

Thanks :)

Instead of instantiating as follows:

TestRestTemplate restTemplate = new TestRestTemplate();

Just do it like this:

TestRestTemplate restTemplate = new TestRestTemplate(user, password);

It works for me, I hope it helps!

I was getting this same warning everytime I was doing 'maven clean'. I found the solution :

Step - 1 Right click on your project in Eclipse

Step - 2 Click Properties

Step - 3 Select Maven in the left hand side list.

Step - 4 You will notice "pom.xml" in the Active Maven Profiles text box on the right hand side. Clear it and click Apply.

Below is the screen shot :

Hope this helps. :)

Check that you have database dependency at runtime group at build.gradle

runtime group: 'com.h2database', name: 'h2', version: '1.4.194'

or change scope from test to runtime if you use Maven

<dependency>
    <groupId>com.h2database</groupId>
    <artifactId>h2</artifactId>
    <version>1.4.194</version>
    <scope>runtime</scope>
</dependency>

You can also try using the one-jar maven plugin which fixed the problem for us. Simply follow the instructions from here.

This works for my boot application in case it helps. This class tells you what properties the config object is looking for:

https://github.com/brettwooldridge/HikariCP/blob/2.3.x/hikaricp-common/src/main/java/com/zaxxer/hikari/AbstractHikariConfig.java

I think multiple datasources could be supporting by adding datasource_whatever to the property keys in the source config file. Cheers!

@Configuration
class DataSourceConfig {

   @Value('${spring.datasource.username}')
   private String user;

   @Value('${spring.datasource.password}')
   private String password;

   @Value('${spring.datasource.url}')
   private String dataSourceUrl;

   @Value('${spring.datasource.dataSourceClassName}')
   private String dataSourceClassName;

   @Value('${spring.datasource.connectionTimeout}')
   private int connectionTimeout;

   @Value('${spring.datasource.maxLifetime}')
   private int maxLifetime;

   @Bean
   public DataSource primaryDataSource() {
      Properties dsProps = [url: dataSourceUrl, user: user, password: password]
      Properties configProps = [
            connectionTestQuery: 'select 1 from dual',
            connectionTimeout: connectionTimeout,
            dataSourceClassName: dataSourceClassName,
            dataSourceProperties: dsProps,
            maxLifetime: maxLifetime
      ]

      // A default max pool size of 10 seems reasonable for now, so no need to configure for now.
      HikariConfig hc = new HikariConfig(configProps)
      HikariDataSource ds = new HikariDataSource(hc)
      ds
   }
}

if You are using browser it default always works on get, u can work with postman tool,otherwise u can change it to getmapping.hope this will works

Javadocs don't offer any special tools for external links, so you should just use standard html:

See <a href="http://groversmill.com/">Grover's Mill</a> for a history of the
Martian invasion.

or

@see <a href="http://groversmill.com/">Grover's Mill</a> for a history of 
the Martian invasion.

Don't use {@link ...} or {@linkplain ...} because these are for links to the javadocs of other classes and methods.

As of now (Jan 2017 / Angular > 2.0) you can use the following:

changeBackground(): any {
    return { 'background-color': this.color };
}

and

<div class="circle" [ngStyle]="changeBackground()">
    <!-- <content></content> --> <!-- content is now deprecated -->
    <ng-content><ng-content> <!-- Use ng-content instead -->
</div>

The shortest way is probably like this:

<div class="circle" [ngStyle]="{ 'background-color': color }">
    <!-- <content></content> --> <!-- content is now deprecated -->
    <ng-content><ng-content> <!-- Use ng-content instead -->
</div>

Add android:exported="true" in your 'com.example.lib.MainActivity' activity tag.

From the android:exported documentation,

android:exported Whether or not the activity can be launched by components of other applications — "true" if it can be, and "false" if not. If "false", the activity can be launched only by components of the same application or applications with the same user ID.

From your logcat output, clearly a mismatch in uid is causing the issue. So adding the android:exported="true" should do the trick.

I know this is an old question, but new in 1.4 is union types; use these for all function overloads (including constructors). Example:

class foo {
    private _name: any;
    constructor(name: string | number) {
        this._name = name;
    }
}
var f1 = new foo("bar");
var f2 = new foo(1);

I'm working on Oracle 12c 12.1. However, doesn't seem like it allows more than 30 characters for column/table names.

Read through an oracle page which mentions 30 bytes. https://docs.oracle.com/database/121/SQLRF/sql_elements008.htm#SQLRF00223

In 12c although the all_tab_columns do say VARCHAR2(128) for Table_Name, it does not allow more than 30 bytes name.

Found another article about 12c R2, which seems to be allowing this up to 128 characters. https://community.oracle.com/ideas/3338

Or try pure ES6 nonlodash method like this

const reducer = (array, object) => {
  array.push(object.a)
  return array
}

var objects = [{ 'a': 1 }, { 'a': 2 }];
objects.reduce(reducer, [])

First create a table in the database with same numbers of columns that are in the csv file.

Then use following query

LOAD DATA INFILE 'D:/Projects/testImport.csv' INTO TABLE cardinfo
FIELDS TERMINATED BY ',' ENCLOSED BY '"'
LINES TERMINATED BY '\r\n'

There's no such thing as a global variable in C#. Period.

You can have static members if you want:

public static class MyStaticValues
{
   public static bool MyStaticBool {get;set;}
}

you can also use:

var path = System.Web.Hosting.HostingEnvironment.MapPath("~/App_Data/myfile.txt")

if

var path = Server.MapPath("~/App_Data");
var fullpath = Path.Combine(path , "myfile.txt");

is inaccessible

I'm not sure I understand your question. But there are two approaches to making the image invisible...

Pure HTML

<img src="a.gif" style="display: none;" />

Or...

HTML + Javascript

<script type="text/javascript">
document.getElementById("myImage").style.display = "none";
</script>

<img id="myImage" src="a.gif" />

Update for Swift 3:

// Create the AlertController and add its actions like button in ActionSheet
let actionSheetController = UIAlertController(title: "Please select", message: "Option to select", preferredStyle: .actionSheet)

let cancelActionButton = UIAlertAction(title: "Cancel", style: .cancel) { action -> Void in
    print("Cancel")
}
actionSheetController.addAction(cancelActionButton)

let saveActionButton = UIAlertAction(title: "Save", style: .default) { action -> Void in
    print("Save")
}
actionSheetController.addAction(saveActionButton)

let deleteActionButton = UIAlertAction(title: "Delete", style: .default) { action -> Void in
    print("Delete")
}
actionSheetController.addAction(deleteActionButton)
self.present(actionSheetController, animated: true, completion: nil)

var objToJson = { };
objToJson.response = response;
response.write(JSON.stringify(objToJson));

If you alert(JSON.stringify(objToJson)) you will get {"response":"value"}

In case someone is still wondering how to do this without jQuery.

HTML

<textarea id="description"></textarea>

Javascript

const textarea = document.getElementById('description');

textarea.addEventListener('keypress', (e) => {
    e.keyCode === 13 && !e.shiftKey && e.preventDefault(); 
})

Vanilla JS

var textarea = document.getElementById('description');

textarea.addEventListener('keypress', function(e) {
    if(e.keyCode === 13 && !e.shiftKey) {
      e.preventDefault();
    }
})

Swift 3

let rootViewController = UIApplication.shared.keyWindow?.rootViewController

async await is here (ES7), so you can do this kind of things very easily now.

  var i;
  var j = 10;
  for (i = 0; i < j; i++) {
    await asycronouseProcess();
    alert(i);
  }

Remember, this works only if asycronouseProcess is returning a Promise

If asycronouseProcess is not in your control then you can make it return a Promise by yourself like this

function asyncProcess() {
  return new Promise((resolve, reject) => {
    asycronouseProcess(()=>{
      resolve();
    })
  })
}

Then replace this line await asycronouseProcess(); by await asyncProcess();

Understanding Promises before even looking into async await is must (Also read about support for async await)

Do this:

$(document).ready(function(){
    $(".header").click(function(){
        $(this).children(".children").toggle();
    });
   $(".header a").click(function(e) {
        e.stopPropagation();
   });
});

If you want to read more on .stopPropagation(), look here.

The problem was solved by reinstalling Visual Studio 2015.

The below code should apply different CSS classes based on your Model's CanEdit Property value .

<div class="@(Model.CanEdit?"visible-item":"hidden-item")">Some links</div>

But if it is something important like Edit/Delete links, you shouldn't be simply hiding,because people can update the css class/HTML markup in their browser and get access to your important link. Instead you should be simply not Rendering the important stuff to the browser.

@if(Model.CanEdit)
{
  <div>Edit/Delete link goes here</div>
}

Update 1

As pointed by @EmJiHash PercentRelativeLayout is deprecated in API level 26.0.0

Below quoting google comment:

This class was deprecated in API level 26.0.0. consider using ConstraintLayout and associated layouts instead. The following shows how to replicate the functionality of percentage layouts with a ConstraintLayout

Google introduced new API called android.support.percent

Then you can just specify percentage to take by view

Add compile dependency like

implementation 'com.android.support:percent:22.2.0

in that, PercentRelativeLayout is what we can do a percentage wise layout

 <android.support.percent.PercentRelativeLayout
     xmlns:android="http://schemas.android.com/apk/res/android"
     xmlns:app="http://schemas.android.com/apk/res-auto"
     android:layout_width="match_parent"
     android:layout_height="match_parent">
     <ImageView
         app:layout_widthPercent="50%"
         app:layout_heightPercent="50%"
         app:layout_marginTopPercent="25%"
         app:layout_marginLeftPercent="25%"/>
 </android.support.percent.PercentRelativeLayout>

Something like this.

function addRowHandlers() {
  var table = document.getElementById("tableId");
  var rows = table.getElementsByTagName("tr");
  for (i = 0; i < rows.length; i++) {
    var currentRow = table.rows[i];
    var createClickHandler = function(row) {
      return function() {
        var cell = row.getElementsByTagName("td")[0];
        var id = cell.innerHTML;
        alert("id:" + id);
      };
    };
    currentRow.onclick = createClickHandler(currentRow);
  }
}

EDIT

Working demo.

I think the "best answer" above, albeit programmatically accurate, does not actually answer the question posed. the question asks how to change the pointer in the mouseover event. I see posts about how one may have an error somewhere is not answering the question. In the accepted answer, the mouseover event is blank (onmouseover="") and the style option, instead, is included. Baffling why this was done.

There may be nothing wrong with the inquirer's link. consider the following html:

<a id=test_link onclick="alert('kinda neat);">Click ME!</a>

When a user mouse's over this link, the pointer will not change to a hand...instead, the pointer will behave like it's hovering over normal text. One might not want this...and so, the mouse pointer needs to be told to change.

the answer being sought for is this (which was posted by another):

<a id=test_link onclick="alert('Nice!');"
       onmouseover="this.style.cursor='pointer';">Click ME!</a>

However, this is ... a nightmare if you have lots of these, or use this kind of thing all over the place and decide to make some kind of a change or run into a bug. better to make a CSS class for it:

a.lendhand {
  cursor: pointer;
}

then:

<a class=lendhand onclick="alert('hand is lent!');">Click ME!</a>

there are many other ways which would be, arguably, better than this method. DIVs, BUTTONs, IMGs, etc might prove more useful. I see no harm in using <a>...</a>, though.

jarett.

You can finish the Acivity and recreate it afterwards in this way your activity will be created again and all the views will be created with the new theme.

I Hope below code will help someone ..!!! :)

jQuery(document).ready(function(){

    jQuery("input[type=submit]").prop('disabled', true);

    jQuery("input[name=textField]").focusin(function(){
        jQuery("input[type=submit]").prop('disabled', false);
    });

    jQuery("input[name=textField]").focusout(function(){
        var checkvalue = jQuery(this).val();
        if(checkvalue!=""){
            jQuery("input[type=submit]").prop('disabled', false);
        }
        else{
            jQuery("input[type=submit]").prop('disabled', true);
        }
    });

}); /*DOC END*/

From the man page:

Sending mail

To send a message to one or more people, mailx can be invoked with arguments which are the names of people to whom the mail will be sent. The user is then expected to type in his message, followed by an ‘control-D’ at the beginning of a line.

In other words, mailx reads the content to send from standard input and can be redirected to like normal. E.g.:

ls -l $HOME | mailx -s "The content of my home directory" [email protected]

This should do the trick:

$($.parseJSON(data.msg)).map(function () {
    return $('<option>').val(this.value).text(this.label);
}).appendTo('#combobox');

Here's the distinction between ajax and getJSON (from the jQuery documentation):

[getJSON] is a shorthand Ajax function, which is equivalent to:

$.ajax({
  url: url,
  dataType: 'json',
  data: data,
  success: callback
});

EDIT: To be clear, part of the problem was that the server's response was returning a json object that looked like this:

{
    "msg": '[{"value":"1","label":"xyz"}, {"value":"2","label":"abc"}]'
}

...So that msg property needed to be parsed manually using $.parseJSON().

For ICS I´ve implemented your code and made a class that extends AsyncTask. I hope you appreciate it! Thanks for your code and solution.

public class UpdateApp extends AsyncTask<String,Void,Void>{
    private Context context;
    public void setContext(Context contextf){
        context = contextf;
    }

    @Override
    protected Void doInBackground(String... arg0) {
        try {
            URL url = new URL(arg0[0]);
            HttpURLConnection c = (HttpURLConnection) url.openConnection();
            c.setRequestMethod("GET");
            c.setDoOutput(true);
            c.connect();

            String PATH = "/mnt/sdcard/Download/";
            File file = new File(PATH);
            file.mkdirs();
            File outputFile = new File(file, "update.apk");
            if(outputFile.exists()){
                outputFile.delete();
            }
            FileOutputStream fos = new FileOutputStream(outputFile);

            InputStream is = c.getInputStream();

            byte[] buffer = new byte[1024];
            int len1 = 0;
            while ((len1 = is.read(buffer)) != -1) {
                fos.write(buffer, 0, len1);
            }
            fos.close();
            is.close();

            Intent intent = new Intent(Intent.ACTION_VIEW);
            intent.setDataAndType(Uri.fromFile(new File("/mnt/sdcard/Download/update.apk")), "application/vnd.android.package-archive");
            intent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK); // without this flag android returned a intent error!
            context.startActivity(intent);


        } catch (Exception e) {
            Log.e("UpdateAPP", "Update error! " + e.getMessage());
        }
        return null;
    }
}   

To use it, in your main activity call by this way:

atualizaApp = new UpdateApp();
atualizaApp.setContext(getApplicationContext());
atualizaApp.execute("http://serverurl/appfile.apk");

Gavin,

The issue you are having is a misunderstanding of positioning. If you want it to be "fixed" relative to the parent, then you really want your #fixed to be position:absolute which will update its position relative to the parent.

This question fully describes positioning types and how to use them effectively.

In summary, your CSS should be

#wrap{ 
    position:relative;
}
#fixed{ 
    position:absolute;
    top:30px;
    left:40px;
}

Pickle uses different protocols to convert your data to a binary stream.

• In python 2 there are 3 different protocols (0, 1, 2) and the default is 0.

• In python 3 there are 5 different protocols (0, 1, 2, 3, 4) and the default is 3.

You must specify in python 3 a protocol lower than 3 in order to be able to load the data in python 2. You can specify the protocol parameter when invoking pickle.dump.

You remove the original image here:

newImg.animate(css, SPEED, function() {
    img.remove();
    newImg.removeClass('morpher');
    (callback || function() {})();
});

And all that's left behind is newImg. Then you reset link references the image using #rocket:

$("#rocket").attr('src', ...

But your newImg doesn't have an id attribute let alone an id of rocket.

To fix this, you need to remove img and then set the id attribute of newImg to rocket:

newImg.animate(css, SPEED, function() {
    var old_id = img.attr('id');
    img.remove();
    newImg.attr('id', old_id);
    newImg.removeClass('morpher');
    (callback || function() {})();
});

And then you'll get the shiny black rocket back again: http://jsfiddle.net/ambiguous/W2K9D/

UPDATE: A better approach (as noted by mellamokb) would be to hide the original image and then show it again when you hit the reset button. First, change the reset action to something like this:

$("#resetlink").click(function(){
    clearInterval(timerRocket);
    $("#wrapper").css('top', '250px');
    $('.throbber, .morpher').remove(); // Clear out the new stuff.
    $("#rocket").show();               // Bring the original back.
});

And in the newImg.load function, grab the images original size:

var orig = {
    width: img.width(),
    height: img.height()
};

And finally, the callback for finishing the morphing animation becomes this:

newImg.animate(css, SPEED, function() {
    img.css(orig).hide();

The leaking of $('.throbber, .morpher') outside the plugin isn't the best thing ever but it isn't a big deal as long as it is documented.

There's also

int[] array = {-1, -1, -1, -1, -1, -1, -1, -1, -1, -1};

If you want to access redis from the host (127.0.0.1), you have to use the ports command.

redis:
  build:
    context: .
    dockerfile: Dockerfile-redis
    ports:
    - "6379:6379"

In this scenario, the outer <div> has a width and height of 90%. The inner div> has a width of 100% of its parent. Both scale when re-sizing the window.

HTML

<div>
    <div>Hello there</div>
</div>

CSS

html, body {
    width: 100%;
    height: 100%;
}

body > div {
    width: 90%;
    height: 100%;
    background: green;
}

body > div > div {
    width: 100%;
    background: red;
}

A rather nice addition to @MartijnPieters answer is to get back a dictionary sorted by occurrence since Collections.most_common only returns a tuple. I often couple this with a json output for handy log files:

from collections import Counter, OrderedDict

x = Counter({'a':5, 'b':3, 'c':7})
y = OrderedDict(x.most_common())

With the output:

OrderedDict([('c', 7), ('a', 5), ('b', 3)])
{
  "c": 7, 
  "a": 5, 
  "b": 3
}

Do you need to post the the form to an URL or do you only need to detect the submit-event? Because you can detect the submit-event by adding onsubmit="javascript:alert('I do also submit');"

<form action="javascript:alert('submitted');" method="post" id="testForm" onsubmit="javascript:alert('I do also submit');">...</form>

Not sure that this is what you are looking for though.

var text = `xxx  df dfvdfv  df    
                     dfv`.split(/[\s,\t,\r,\n]+/).filter(x=>x).join(' ');

result:

"xxx df dfvdfv df dfv"

This is how I organized my application's static resources.

In simple terms, the reasons are as follows.

1. Object has monitors.
2. Multiple threads can access one Object. Only one thread can hold object monitor at a time for synchronized methods/blocks.
3. wait(), notify() and notifyAll() method being in Object class allows all the threads created on that object to communicate with other
4. Locking ( using synchronized or Lock API) and Communication (wait() and notify()) are two different concepts.

If Thread class contains wait(), notify() and notifyAll() methods, then it will create below problems:

1. Thread communication problem
2. Synchronization on object won’t be possible. If each thread will have monitor, we won’t have any way of achieving synchronization
3. Inconsistency in state of object

Refer to this article for more details.

You can use the filter function to apply more complicated regex matching.

Here's an example which would just match the first three divs:

$('div')_x000D_
  .filter(function() {_x000D_
    return this.id.match(/abc+d/);_x000D_
  })_x000D_
  .html("Matched!");

<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>_x000D_
_x000D_
<div id="abcd">Not matched</div>_x000D_
<div id="abccd">Not matched</div>_x000D_
<div id="abcccd">Not matched</div>_x000D_
<div id="abd">Not matched</div>

Convert String to Int

var myInt = int.parse('12345');
assert(myInt is int);
print(myInt); // 12345

assert(myInt is double);
print(myDouble); // 123.45
print(myDouble.runtimeType);

This question was asked quite a long time ago. For anyone just seeing this question, there is now a site called "you might not need jquery" which breaks down - by level of IE support required - all the functionality of jquery and provides some alternative, smaller libraries.

IE8 document ready script according to you might not need jquery

function ready(fn) {
    if (document.readyState != 'loading')
        fn();
    else if (document.addEventListener)
        document.addEventListener('DOMContentLoaded', fn);
    else
        document.attachEvent('onreadystatechange', function() {
            if (document.readyState != 'loading')
                fn();
        });
}

Think of a GrantedAuthority as being a "permission" or a "right". Those "permissions" are (normally) expressed as strings (with the getAuthority() method). Those strings let you identify the permissions and let your voters decide if they grant access to something.

You can grant different GrantedAuthoritys (permissions) to users by putting them into the security context. You normally do that by implementing your own UserDetailsService that returns a UserDetails implementation that returns the needed GrantedAuthorities.

Roles (as they are used in many examples) are just "permissions" with a naming convention that says that a role is a GrantedAuthority that starts with the prefix ROLE_. There's nothing more. A role is just a GrantedAuthority - a "permission" - a "right". You see a lot of places in spring security where the role with its ROLE_ prefix is handled specially as e.g. in the RoleVoter, where the ROLE_ prefix is used as a default. This allows you to provide the role names withtout the ROLE_ prefix. Prior to Spring security 4, this special handling of "roles" has not been followed very consistently and authorities and roles were often treated the same (as you e.g. can see in the implementation of the hasAuthority() method in SecurityExpressionRoot - which simply calls hasRole()). With Spring Security 4, the treatment of roles is more consistent and code that deals with "roles" (like the RoleVoter, the hasRole expression etc.) always adds the ROLE_ prefix for you. So hasAuthority('ROLE_ADMIN') means the the same as hasRole('ADMIN') because the ROLE_ prefix gets added automatically. See the spring security 3 to 4 migration guide for futher information.

But still: a role is just an authority with a special ROLE_ prefix. So in Spring security 3 @PreAuthorize("hasRole('ROLE_XYZ')") is the same as @PreAuthorize("hasAuthority('ROLE_XYZ')") and in Spring security 4 @PreAuthorize("hasRole('XYZ')") is the same as @PreAuthorize("hasAuthority('ROLE_XYZ')").

Regarding your use case:

Users have roles and roles can perform certain operations.

You could end up in GrantedAuthorities for the roles a user belongs to and the operations a role can perform. The GrantedAuthorities for the roles have the prefix ROLE_ and the operations have the prefix OP_. An example for operation authorities could be OP_DELETE_ACCOUNT, OP_CREATE_USER, OP_RUN_BATCH_JOBetc. Roles can be ROLE_ADMIN, ROLE_USER, ROLE_OWNER etc.

You could end up having your entities implement GrantedAuthority like in this (pseudo-code) example:

@Entity
class Role implements GrantedAuthority {
    @Id
    private String id;

    @ManyToMany
    private final List<Operation> allowedOperations = new ArrayList<>();

    @Override
    public String getAuthority() {
        return id;
    }

    public Collection<GrantedAuthority> getAllowedOperations() {
        return allowedOperations;
    }
}

@Entity
class User {
    @Id
    private String id;

    @ManyToMany
    private final List<Role> roles = new ArrayList<>();

    public Collection<Role> getRoles() {
        return roles;
    }
}

@Entity
class Operation implements GrantedAuthority {
    @Id
    private String id;

    @Override
    public String getAuthority() {
        return id;
    }
}

The ids of the roles and operations you create in your database would be the GrantedAuthority representation, e.g. ROLE_ADMIN, OP_DELETE_ACCOUNT etc. When a user is authenticated, make sure that all GrantedAuthorities of all its roles and the corresponding operations are returned from the UserDetails.getAuthorities() method.

Example: The admin role with id ROLE_ADMIN has the operations OP_DELETE_ACCOUNT, OP_READ_ACCOUNT, OP_RUN_BATCH_JOB assigned to it. The user role with id ROLE_USER has the operation OP_READ_ACCOUNT.

If an admin logs in the resulting security context will have the GrantedAuthorities: ROLE_ADMIN, OP_DELETE_ACCOUNT, OP_READ_ACCOUNT, OP_RUN_BATCH_JOB

If a user logs it, it will have: ROLE_USER, OP_READ_ACCOUNT

The UserDetailsService would take care to collect all roles and all operations of those roles and make them available by the method getAuthorities() in the returned UserDetails instance.

I recommend you start reading the documentation (4.6.18. Formatting cells). When applying a lot of formatting it's better to use applyFromArray() According to the documentation this method is also suppose to be faster when you're setting many style properties. There's an annex where you can find all the possible keys for this function.

This will work for you:

$phpExcel = new PHPExcel();

$styleArray = array(
    'font'  => array(
        'bold'  => true,
        'color' => array('rgb' => 'FF0000'),
        'size'  => 15,
        'name'  => 'Verdana'
    ));

$phpExcel->getActiveSheet()->getCell('A1')->setValue('Some text');
$phpExcel->getActiveSheet()->getStyle('A1')->applyFromArray($styleArray);

To apply font style to complete excel document:

 $styleArray = array(
   'font'  => array(
        'bold'  => true,
        'color' => array('rgb' => 'FF0000'),
        'size'  => 15,
        'name'  => 'Verdana'
    ));      
 $phpExcel->getDefaultStyle()
    ->applyFromArray($styleArray);

Python has two different ways to convert an object to a string: str() and repr(). Printing an object uses str(); printing a list containing an object uses str() for the list itself, but the implementation of list.__str__() calls repr() for the individual items.

So you should also overwrite __repr__(). A simple

__repr__ = __str__

at the end of the class body will do the trick.

worked for me too:

SimpleDateFormat sdf = new SimpleDateFormat("dd/MM/yyyy");
    Date parsed = null;
    try {
        parsed = sdf.parse("02/01/2014");
    } catch (ParseException e1) {
        // TODO Auto-generated catch block
        e1.printStackTrace();
    }
    java.sql.Date data = new java.sql.Date(parsed.getTime());
    contato.setDataNascimento( data);

    // Contato DataNascimento era Calendar
    //contato.setDataNascimento(Calendar.getInstance());         

    // grave nessa conexão!!! 
    ContatoDao dao = new ContatoDao("mysql");           

    // método elegante 
    dao.adiciona(contato); 
    System.out.println("Banco: ["+dao.getNome()+"] Gravado! Data: "+contato.getDataNascimento());

I understand you want to open a xml file using php. That's called to parse a xml file. The best reference is here.

http://php.net/manual/de/function.xml-parse.php

It somewhat depends on what you use as a CGI framework, but they are available in dictionaries accessible to the program. I'd point you to the docs, but I'm not getting through to python.org right now. But this note on mail.python.org will give you a first pointer. Look at the CGI and URLLIB Python libs for more.

Update

Okay, that link busted. Here's the basic wsgi ref

Nope, you can't abort an "each" without throwing an exception. You likely want a classic loop if you want the break to abort under a particular condition.

Alternatively, you could use a "find" closure instead of an each and return true when you would have done a break.

This example will abort before processing the whole list:

def a = [1, 2, 3, 4, 5, 6, 7]

a.find { 
    if (it > 5) return true // break
    println it  // do the stuff that you wanted to before break
    return false // keep looping
}

Prints

1
2
3
4
5

but doesn't print 6 or 7.

It's also really easy to write your own iterator methods with custom break behavior that accept closures:

List.metaClass.eachUntilGreaterThanFive = { closure ->
    for ( value in delegate ) {
        if ( value  > 5 ) break
        closure(value)
    }
}

def a = [1, 2, 3, 4, 5, 6, 7]

a.eachUntilGreaterThanFive {
    println it
}

Also prints:

1
2
3
4
5    

position: absolute will position the element by coordinates, relative to the closest positioned ancestor, i.e. the closest parent which isn't position: static.

Have your four divs nested inside the target div, give the target div position: relative, and use position: absolute on the others.

Structure your HTML similar to this:

<div id="container">
  <div class="top left"></div>
  <div class="top right"></div>
  <div class="bottom left"></div>
  <div class="bottom right"></div>
</div>

And this CSS should work:

#container {
  position: relative;
}

#container > * {
  position: absolute;
}

.left {
  left: 0;
}

.right {
  right: 0;
}

.top {
  top: 0;
}

.bottom {
  bottom: 0;
}

...

The meaning of the completely undocumented error 800A03EC (shame on Microsoft!) is something like "OPERATION NOT SUPPORTED".

It may happen

• when you open a document that has a content created by a newer Excel version, which your current Excel version does not understand.
• when you save a document to the same path where you have loaded it from (file is already open and locked)

But mostly you will see this error due to severe bugs in Excel.

• For example Microsoft.Office.Interop.Excel.Picture has a property "Enabled". When you call it you should receive a bool value. But instead you get an error 800A03EC. This is a bug.
• And there is a very fat bug in Exel 2013 and 2016: When you automate an Excel process and set Application.Visible=true and Application.WindowState = XlWindowState.xlMinimized then you will get hundreds of 800A03EC errors from different functions (like Range.Merge(), CheckBox.Text, Shape.TopLeftCell, Shape.Locked and many more). This bug does not exist in Excel 2007 and 2010.

Bit late to this...I'm surprised that no one mentioned Symfony's VarDumper component that Laravel includes, in part, for its dd() (and lesser-known, dump()) utility functions.

$dumpMe = new App\User([ 'name' => 'Cy Rossignol' ]);

(new Symfony\Component\VarDumper\Dumper\CliDumper())->dump( 
    (new Symfony\Component\VarDumper\Cloner\VarCloner())->cloneVar($dumpMe)
);

There's a bit more code needed, but, in return, we get nice formatted, readable output in the console—especially useful for debugging complex objects or arrays:

App\User {#17
  #attributes: array:1 [
    "name" => "Cy Rossignol"
  ]
  #fillable: array:3 [
    0 => "name"
    1 => "email"
    2 => "password"
  ]
  #guarded: array:1 [
    0 => "*"
  ]
  #primaryKey: "id"
  #casts: []
  #dates: []
  #relations: []
  ... etc ...
}

To take this a step further, we can even colorize the output! Add this helper function to the project to save some typing:

function toConsole($var) 
{
    $dumper = new Symfony\Component\VarDumper\Dumper\CliDumper();
    $dumper->setColors(true);

    $dumper->dump((new Symfony\Component\VarDumper\Cloner\VarCloner())->cloneVar($var));
}

If we're running the app behind a full webserver (like Apache or Nginx—not artisan serve), we can modify this function slightly to send the dumper's prettified output to the log (typically storage/logs/laravel.log):

function toLog($var) 
{
    $lines = [ 'Dump:' ];
    $dumper = new Symfony\Component\VarDumper\Dumper\CliDumper();
    $dumper->setColors(true);
    $dumper->setOutput(function ($line) use (&$lines) { 
        $lines[] = $line;
    });

    $dumper->dump((new Symfony\Component\VarDumper\Cloner\VarCloner())->cloneVar($var));

    Log::debug(implode(PHP_EOL, $lines));
}

...and, of course, watch the log using:

$ tail -f storage/logs/laravel.log

PHP's error_log() works fine for quick, one-off inspection of simple values, but the functions shown above take the hard work out of debugging some of Laravel's more complicated classes.

EDIT: I'm torn on whether to delete this post. As a matter of understanding the CSS syntax, it's good that people know all exists, and it may at times be preferable to a million individual declarations, depending on the structure of your CSS. On the other hand, it may have a performance penalty, although I've yet to see any data supporting that hypothesis. For now, I'll leave it, but I want people to be aware it's a mixed bag.

Original post:

You can also simply significantly with:

.nav a {
    transition: all .2s;
}

FWIW: all is implied if not specified, so transition: .2s; will get you to the same place.

First, in bash "[" is just a command, which expects string "]" as a last argument, so the whitespace before the closing bracket (as well as between "!" and "-d" which need to be two separate arguments too) is important:

if [ ! -d /home/mlzboy/b2c2/shared/db ]; then
  mkdir -p /home/mlzboy/b2c2/shared/db;
fi

Second, since you are using -p switch to mkdir, this check is useless, because this is what does in the first place. Just write:

mkdir -p /home/mlzboy/b2c2/shared/db;

and thats it.

ES6 solution

using Array#some and Object.keys. It will return true if given key exists in the object or false if it doesn't.

var obj = {foo: 'one', bar: 'two'};_x000D_
    _x000D_
function isKeyInObject(obj, key) {_x000D_
    var res = Object.keys(obj).some(v => v == key);_x000D_
    console.log(res);_x000D_
}_x000D_
_x000D_
isKeyInObject(obj, 'foo');_x000D_
isKeyInObject(obj, 'something');

One-line example.

console.log(Object.keys({foo: 'one', bar: 'two'}).some(v => v == 'foo'));

If you just want the list, then you should ask here: http://unix.stackexchange.com

The answer is: cd / && find -name *.js

If you want to implement this, you have to specify the language.

"Topology was destroyed" might be caused by mongoose disconnecting before mongo document indexes are created, per this comment

In order to make sure all models have their indexes built before disconnecting, you can:

await Promise.all(mongoose.modelNames().map(model => mongoose.model(model).ensureIndexes()));

await mongoose.disconnect();

Take a look at the .classpath file in your project, which probably contains most of the information that you want. The easiest option may be to roll your own "build.xml export", i.e. process .classpath into a new build.xml during the build itself, and then call it with an ant subtask.

Parsing a little XML sounds much easier to me than to hook into Eclipse JDT.

This answer is likely not what you're looking for. I wanted a singleton in the sense that only that object had its identity, for comparison to. In my case it was being used as a Sentinel Value. To which the answer is very simple, make any object mything = object() and by python's nature, only that thing will have its identity.

#!python
MyNone = object()  # The singleton

for item in my_list:
    if item is MyNone:  # An Example identity comparison
        raise StopIteration

This will return pure class name even when using namespace:

echo substr(strrchr(__CLASS__, "\\"), 1);    

With eager evaluation, variables essentially turn into their values any time you look at them (to paraphrase). That said, Python does have built-in namespaces. For example, locals() will return a dictionary mapping a function's variables' names to their values, and globals() does the same for a module. Thus:

for name, value in globals().items():
    if value is unknown_variable:
        ... do something with name

Note that you don't need to import anything to be able to access locals() and globals().

Also, if there are multiple aliases for a value, iterating through a namespace only finds the first one.

This will get you the row count, but will leave the data reader at the end.

dataReader.Cast<object>().Count();

I believe you may need the Typescript typings for JQuery. Since you said you're using Visual Studio, you could use Nuget to get them.

https://www.nuget.org/packages/jquery.TypeScript.DefinitelyTyped/

The command in Nuget Package Manager Console is

Install-Package jquery.TypeScript.DefinitelyTyped

Update: As noted in the comment this package hasn't been updated since 2016. But you can still visit their Github page at https://github.com/DefinitelyTyped/DefinitelyTyped and download the types. Navigate the folder for your library and then download the index.d.ts file there. Pop it anywhere in your project directory and VS should use it right away.

This solution allows all keyboard functionality including copy paste with keyboard. It prevents pasting of negative numbers with the mouse. It works with all browsers and the demo on codepen uses bootstrap and jQuery. This should work with non english language settings and keyboards. If the browser doesn't support the paste event capture (IE), it will remove the negative sign after focus out. This solution behaves as the native browser should with min=0 type=number.

    if (the_val > 0) {
      $(this).val(the_val.toFixed(2));
    }
  });

  $("input.positive-numeric-only").focusout(function(e) {
    if (!isNaN(this.value) && this.value.length != 0) {
      this.value = Math.abs(parseFloat(this.value)).toFixed(2);
    } else {
      this.value = 0;
    }
  });
});

I run into the same problem and learn that queue module defines classes and exceptions, that defines the public methods (Queue Objects).

Ex.

workQueue = queue.Queue(10)

another.obj = [obj copyWithZone: zone];

I think, that this line causes memory leak, because you access to obj through property which is (I assume) declared as retain. So, retain count will be increased by property and copyWithZone.

I believe it should be:

another.obj = [[obj copyWithZone: zone] autorelease];

or:

SomeOtherObject *temp = [obj copyWithZone: zone];
another.obj = temp;
[temp release]; 

A good place to start is the IE Standards Support Documentation.

Here is how to target IE10 in JavaScript:

if ("onpropertychange" in document && !!window.matchMedia) {
...
}

Here is how to target IE10 in CSS:

@media all and (-ms-high-contrast: none) {
...
}

In case IE11 needs to be filtered or reset via CSS, see another question: How to write a CSS hack for IE 11?

what platform are you running?..
if its unix, maybe adding

alias java='java -Xmx1g'  

to .bashrc (or similar) work

edit: Changing XmX to Xmx

Can the problem be with the "a.mProperty > b.mProperty" line? I've gotten the following code to work:

#include <algorithm>
#include <vector>
#include <iterator>
#include <iostream>
#include <sstream>

struct Foo
{
    Foo() : _i(0) {};

    int _i;

    friend std::ostream& operator<<(std::ostream& os, const Foo& f)
    {
        os << f._i;
        return os;
    };
};

typedef std::vector<Foo> VectorT;

std::string toString(const VectorT& v)
{
    std::stringstream ss;
    std::copy(v.begin(), v.end(), std::ostream_iterator<Foo>(ss, ", "));
    return ss.str();
};

int main()
{

    VectorT v(10);
    std::for_each(v.begin(), v.end(),
            [](Foo& f)
            {
                f._i = rand() % 100;
            });

    std::cout << "before sort: " << toString(v) << "\n";

    sort(v.begin(), v.end(),
            [](const Foo& a, const Foo& b)
            {
                return a._i > b._i;
            });

    std::cout << "after sort:  " << toString(v) << "\n";
    return 1;
};

The output is:

before sort: 83, 86, 77, 15, 93, 35, 86, 92, 49, 21,
after sort:  93, 92, 86, 86, 83, 77, 49, 35, 21, 15,

OK, let's go a bit more comprehensive and start with what's Map for those who don't know this feature in JavaScript... MDN says:

The Map object holds key-value pairs and remembers the original insertion order of the keys.
Any value (both objects and primitive values) may be used as either a key or a value.

As you mentioned, you can easily create an instance of Map using new keyword... In your case:

let myMap = new Map().set('a', 1).set('b', 2);

So let's see...

The way you mentioned is an OK way to do it, but yes, there are more concise ways to do that...

Map has many methods which you can use, like set() which you already used to assign the key values...

One of them is keys() which returns all the keys...

In your case, it will return:

MapIterator {"a", "b"}

and you easily convert them to an Array using ES6 ways, like spread operator...

const b = [...myMap.keys()];

I know this is a bit of an old question, but I've ended up making my own little class for it.

Might be useful to someone so I'll stick it up. I used a class variable, which is inherently persistent, to ensure sufficient whitespace was added to clear any old lines. See below:

class consolePrinter():
'''
Class to write to the console

Objective is to make it easy to write to console, with user able to 
overwrite previous line (or not)
'''
# -------------------------------------------------------------------------    
#Class variables
stringLen = 0    
# -------------------------------------------------------------------------    
    
# -------------------------------------------------------------------------
def writeline(stringIn, overwriteFlag=False):
    import sys
    #Get length of stringIn and update stringLen if needed
    if len(stringIn) > consolePrinter.stringLen:
        consolePrinter.stringLen = len(stringIn)+1
    
    ctrlString = "{:<"+str(consolePrinter.stringLen)+"}"
    if overwriteFlag:
        sys.stdout.write("\r" + ctrlString.format(stringIn))
    else:
        sys.stdout.write("\n" + stringIn)
    sys.stdout.flush()
    
    return

Which then is called via:

consolePrinter.writeline("text here", True) 

If you want to overwrite the previous line, or

consolePrinter.writeline("text here",False)

if you don't.

Note, for it to work right, all messages pushed to the console would need to be through consolePrinter.writeline.

I had to uncomment extension=openssl in php.ini file for everything to work!

That's right. If you create a shelf, other people doing a get latest won't see your code.

It puts your code changes onto the server, which is probably better backed up than your work PC.

It enables you to pick up your changes on another machine, should you feel the urge to work from home.

Others can see your shelves (though I think this may be optional) so they can review your code prior to a check-in.

If you know you're dealing with ascii text then you can just use a uppercase/lowercase character offset comparison.

Just make sure the string your "perfect" string (the one you want to match against) is lowercase:

const CHARS_IN_BETWEEN = 32;
const LAST_UPPERCASE_CHAR = 90; // Z
function strMatchesIgnoreCase(lowercaseMatch, value) {
    let i = 0, matches = lowercaseMatch.length === value.length;
    while (matches && i < lowercaseMatch.length) {
        const a = lowercaseMatch.charCodeAt(i);
        const A = a - CHARS_IN_BETWEEN;
        const b = value.charCodeAt(i);
        const B = b + ((b > LAST_UPPERCASE_CHAR) ? -CHARS_IN_BETWEEN : CHARS_IN_BETWEEN);
        matches = a === b // lowerA === b
            || A === b // upperA == b
            || a === B // lowerA == ~b
            || A === B; // upperA == ~b
        i++;
    }
    return matches;
}

For me, it works when I double checked the parent´s "group ID" and "artifact ID" that in my case were the wrong ones and that was the problem.

1. Instala grunt de manera global: sudo npm install -g grunt-cli --unsafe-perm=true --allow-root

2. Try to run grunt.

3. If you have this message:

Warning:

You need to have Ruby and Sass installed and in your PATH for this task to work.

More info: https://github.com/gruntjs/grunt-contrib-sass

Used --force, continuing.

3.1. Check that you have ruby installed (mac, you should have it): ruby -v

Disclaimer: This approach is a naive illustration of Ruby's capabilities, and not a production-grade solution for replacing strings in files. It's prone to various failure scenarios, such as data loss in case of a crash, interrupt, or disk being full. This code is not fit for anything beyond a quick one-off script where all the data is backed up. For that reason, do NOT copy this code into your programs.

Here's a quick short way to do it.

file_names = ['foo.txt', 'bar.txt']

file_names.each do |file_name|
  text = File.read(file_name)
  new_contents = text.gsub(/search_regexp/, "replacement string")

  # To merely print the contents of the file, use:
  puts new_contents

  # To write changes to the file, use:
  File.open(file_name, "w") {|file| file.puts new_contents }
end

Method 1: Add an event listener for input:

element.addEventListener("input", myFunction);

Method 2: Define the oninput property with JavaScript:

element.oninput = function()
{
    myFunction();
};

Method 3: Define the oninput property with HTML:

<input type="text" oninput="myFunction();">

only with this:

const a = true; const b = false;

console.log(+a);//1 console.log(+b);//0

I think you mean to use map instead of filter:

>>> from string import upper
>>> mylis=['this is test', 'another test']
>>> map(upper, mylis)
['THIS IS TEST', 'ANOTHER TEST']

Even simpler, you could use str.upper instead of importing from string (thanks to @alecxe):

>>> map(str.upper, mylis)
['THIS IS TEST', 'ANOTHER TEST']

In Python 2.x, map constructs a new list by applying a given function to every element in a list. filter constructs a new list by restricting to elements that evaluate to True with a given function.

In Python 3.x, map and filter construct iterators instead of lists, so if you are using Python 3.x and require a list the list comprehension approach would be better suited.

Since the values are actually inside of an HTML attribute, you should use '

"<img src='something' onmouseover='change(&apos;ex1&apos;)' />";

Using Chart.JS version 2.1.3, answers older than this one aren't valid anymore. Using getSegmentsAtEvent(event) method will output on console this message:

getSegmentsAtEvent is not a function

So i think it must be removed. I didn't read any changelog to be honest. To resolve that, just use getElementsAtEvent(event) method, as it can be found on the Docs.

Below it can be found the script to obtain effectively clicked slice label and value. Note that also retrieving label and value is slightly different.

var ctx = document.getElementById("chart-area").getContext("2d");
var chart = new Chart(ctx, config);

document.getElementById("chart-area").onclick = function(evt)
{   
    var activePoints = chart.getElementsAtEvent(evt);

    if(activePoints.length > 0)
    {
      //get the internal index of slice in pie chart
      var clickedElementindex = activePoints[0]["_index"];

      //get specific label by index 
      var label = chart.data.labels[clickedElementindex];

      //get value by index      
      var value = chart.data.datasets[0].data[clickedElementindex];

      /* other stuff that requires slice's label and value */
   }
}

Hope it helps.

I agree. Once it is uploaded to somewhere the user's browser can access then it is pretty easy to get the size. As you need to wait for the image to load you'll want to hook into the onload event for img.

var width, height;

var img = document.createElement("img");
img.onload = function() {
    // `naturalWidth`/`naturalHeight` aren't supported on <IE9. Fallback to normal width/height
    // The natural size is the actual image size regardless of rendering.
    // The 'normal' width/height are for the **rendered** size.

    width  = img.naturalWidth  || img.width;
    height = img.naturalHeight || img.height; 

    // Do something with the width and height
}

// Setting the source makes it start downloading and eventually call `onload`
img.src = "http://your.website.com/userUploadedImage.jpg";

After :

sockfd = socket(AF_INET, SOCK_STREAM, 0);
if (sockfd < 0) 
    error("ERROR opening socket");

You can add (with standard C99 compound literal support) :

if (setsockopt(sockfd, SOL_SOCKET, SO_REUSEADDR, &(int){1}, sizeof(int)) < 0)
    error("setsockopt(SO_REUSEADDR) failed");

Or :

int enable = 1;
if (setsockopt(sockfd, SOL_SOCKET, SO_REUSEADDR, &enable, sizeof(int)) < 0)
    error("setsockopt(SO_REUSEADDR) failed");

// Its Working 

According to this snippet here, this approach should be good for long strings:

private string StringToHex(string hexstring)
{
    StringBuilder sb = new StringBuilder();
    foreach (char t in hexstring)
    { 
        //Note: X for upper, x for lower case letters
        sb.Append(Convert.ToInt32(t).ToString("x")); 
    }
    return sb.ToString();
}

usage:

string result = StringToHex("Hello world"); //returns "48656c6c6f20776f726c64"

Another approach in one line

string input = "Hello world";
string result = String.Concat(input.Select(x => ((int)x).ToString("x")));

I had a similar issue when attempting to start a process without showing the console window. I tested with several different combinations of property values until I found one that exhibited the behavior I wanted.

Here is a page detailing why the UseShellExecute property must be set to false.
http://msdn.microsoft.com/en-us/library/system.diagnostics.processstartinfo.createnowindow.aspx

Under Remarks section on page:

If the UseShellExecute property is true or the UserName and Password properties are not null, the CreateNoWindow property value is ignored and a new window is created.

ProcessStartInfo startInfo = new ProcessStartInfo();
startInfo.FileName = fullPath;
startInfo.Arguments = args;
startInfo.RedirectStandardOutput = true;
startInfo.RedirectStandardError = true;
startInfo.UseShellExecute = false;
startInfo.CreateNoWindow = true;

Process processTemp = new Process();
processTemp.StartInfo = startInfo;
processTemp.EnableRaisingEvents = true;
try
{
    processTemp.Start();
}
catch (Exception e)
{
    throw;

on mac, if your ssh key need passphrase everytime and you want to skip it, then you can try below, it works fine for me

1. eval "$(ssh-agent -s)"
2. ssh-add -K .ssh/id_rsa
3. add this default ssh configuration works for me

Host *
AddKeysToAgent yes
UseKeychain yes
IdentityFile ~/.ssh/id_rsa

To iterate ASCII characters on a POSIX-compliant shell, you can avoid external tools by using the Parameter Expansions:

#!/bin/sh

str="Hello World!"

while [ ${#str} -gt 0 ]; do
    next=${str#?}
    echo "${str%$next}"
    str=$next
done

or

str="Hello World!"

while [ -n "$str" ]; do
    next=${str#?}
    echo "${str%$next}"
    str=$next
done

All of these are kinds of indices.

primary: must be unique, is an index, is (likely) the physical index, can be only one per table.

unique: as it says. You can't have more than one row with a tuple of this value. Note that since a unique key can be over more than one column, this doesn't necessarily mean that each individual column in the index is unique, but that each combination of values across these columns is unique.

index: if it's not primary or unique, it doesn't constrain values inserted into the table, but it does allow them to be looked up more efficiently.

fulltext: a more specialized form of indexing that allows full text search. Think of it as (essentially) creating an "index" for each "word" in the specified column.

I wrote a directive you can use to bind an ng-model to any expression you want. Whenever the expression changes the model is set to the new value.

 module.directive('boundModel', function() {
      return {
        require: 'ngModel',
        link: function(scope, elem, attrs, ngModel) {
          var boundModel$watcher = scope.$watch(attrs.boundModel, function(newValue, oldValue) {
            if(newValue != oldValue) {
              ngModel.$setViewValue(newValue);
              ngModel.$render();
            }
          });

          // When $destroy is fired stop watching the change.
          // If you don't, and you come back on your state
          // you'll have two watcher watching the same properties
          scope.$on('$destroy', function() {
              boundModel$watcher();
          });
        }
    });

You can use it in your templates like this:

 <li>Total<input type="text" ng-model="total" bound-model="one * two"></li>      

I took some time to check it in detail. I created an icon whose images have sizes of 16, 24, 32, 40, 48, 64, 96, 128 and 256. Then I checked which image is shown. All these were done with normal 96dpi. If using a larger DPI, the larger sizes may be used (only checked this a bit in Windows 7). The results:

Windows XP:

• Explorer views:
  • Details / List: 16
  • Icons: 32
  • Tiles / Thumbnails: 48
• Right-click->Properties / choosing a new icon: 32
• Quickstart area: 16
• Desktop: 32

Windows 7:

• Explorer views:
  • Details / List / Small symbols: 16
  • All other options: 256 (resized, if necessary)
• Right-click->Properties / choosing a new icon: 32
• Pinned to taskbar: 32
  • Right-click-menu: 16
• Desktop:
  • Small symbols: 32
  • Medium symbols: 48
  • Large symbols: 256 (resized, if necessary)
  • Zooming using Ctrl+Mouse wheel: 16, 32, 48, 256

Windows Runtime: (from here)

• Main tile: 150x150, 310x150 (wide version)
• Small logo: 30x30
• Badge (for lockscreen): 24x24, monochromatic
• Splashscreen: 620x300
• Store: 50x50

So the result: Windows XP uses 16, 32, 48-size icons, while Windows 7 (and presumably also Vista) also uses 256-size icons. All other intermediate icon sizes are ignored (they may be used in some area which I didn't check).

I also checked in Windows 7 what happens if icon sizes are missing:

The missing sizes are generated (obviously). With sizes of 16, 32, and 48, if one is missing, downscaling is preferred. So if we have icons with size 16 and 48, the 32 icon is created from the 48 icon. The 256 icon is only used for these if no other sizes are available! So if the icons are size 16 and 256, the other sizes are upscaled from the 16 icon!

Additionally, if the 256 icon is not there, the (possibly generated) 48 icon is used, but not resized anymore. So we have a (possibly large) empty area with the 48 icon in the middle.

Note that the default desktop icon size in XP was 32x32, while in Windows 7 it is 48x48. As a consequence, for Windows 7 it is relatively important to have a 48 icon. Otherwise, it is upscaled from a smaller icon, which may look quite ugly.

Just a note about Windows XP compatibility: If you reuse the icon as window icon, then note that this can crash your application if you use a compressed 256 icon. The solution is to either not compress the icon or create a second version without the (compressed) 256 icon. See here for more info.

Excel doesn't support UTF-8. You have to encode your UTF-8 text into UCS-2LE.

mb_convert_encoding($output, 'UCS-2LE', 'UTF-8');

The danger of the second expression comes if the type of byte1 is char. In that case, some implementations can have it signed char, which will result in sign extension when evaluating.

signed char byte1 = 0x80;
signed char byte2 = 0x10;

unsigned short value1 = ((byte2 << 8) | (byte1 & 0xFF));
unsigned short value2 = ((byte2 << 8) | byte1);

printf("value1=%hu %hx\n", value1, value1);
printf("value2=%hu %hx\n", value2, value2);

will print

value1=4224 1080     right
value2=65408 ff80    wrong!!

I tried it on gcc v3.4.6 on Solaris SPARC 64 bit and the result is the same with byte1 and byte2 declared as char.

TL;DR

The masking is to avoid implicit sign extension.

EDIT: I checked, it's the same behaviour in C++.

EDIT2: As requested explanation of sign extension. Sign extension is a consequence of the way C evaluates expressions. There is a rule in C called promotion rule. C will implicitly cast all small types to int before doing the evaluation. Let's see what happens to our expression:

unsigned short value2 = ((byte2 << 8) | byte1);

byte1 is a variable containing bit pattern 0xFF. If char is unsigned that value is interpreted as 255, if it is signed it is -128. When doing the calculation, C will extend the value to an int size (16 or 32 bits generally). This means that if the variable is unsigned and we will keep the value 255, the bit-pattern of that value as int will be 0x000000FF. If it is signed we want the value -128 which bit pattern is 0xFFFFFFFF. The sign was extended to the size of the tempory used to do the calculation. And thus oring the temporary will yield the wrong result.

On x86 assembly it is done with the movsx instruction (movzx for the zero extend). Other CPU's had other instructions for that (6809 had SEX).

For something reusable:

template<template <typename> class P = std::less >
struct compare_pair_second {
    template<class T1, class T2> bool operator()(const std::pair<T1, T2>& left, const std::pair<T1, T2>& right) {
        return P<T2>()(left.second, right.second);
    }
};

You can use it as

std::sort(foo.begin(), foo.end(), compare_pair_second<>());

or

std::sort(foo.begin(), foo.end(), compare_pair_second<std::less>());

use px for precise placement of graphical elements. use em for measurements having to do positioning and spacing around text elements like line-height etc. px is pixel accurate, em can change dynamically with the font in use

>>> import pandas as pd
>>> df = pd.DataFrame({'Position':[1,2,3,4,5], 'Letter':['a', 'b', 'c', 'd', 'e']})
>>> dict(sorted(df.values.tolist())) # Sort of sorted...

>>> from collections import OrderedDict
>>> OrderedDict(df.values.tolist())
OrderedDict([('a', 1), ('b', 2), ('c', 3), ('d', 4), ('e', 5)])

In Long

Explaining solution: dict(sorted(df.values.tolist()))

Given:

df = pd.DataFrame({'Position':[1,2,3,4,5], 'Letter':['a', 'b', 'c', 'd', 'e']})

[out]:

 Letter Position
0   a   1
1   b   2
2   c   3
3   d   4
4   e   5

Try:

# Get the values out to a 2-D numpy array, 
df.values

[out]:

array([['a', 1],
       ['b', 2],
       ['c', 3],
       ['d', 4],
       ['e', 5]], dtype=object)

Then optionally:

# Dump it into a list so that you can sort it using `sorted()`
sorted(df.values.tolist()) # Sort by key

Or:

# Sort by value:
from operator import itemgetter
sorted(df.values.tolist(), key=itemgetter(1))

[out]:

[['a', 1], ['b', 2], ['c', 3], ['d', 4], ['e', 5]]

Lastly, cast the list of list of 2 elements into a dict.

dict(sorted(df.values.tolist())) 

[out]:

{'a': 1, 'b': 2, 'c': 3, 'd': 4, 'e': 5}

If there are multiple values for a specific key and you would like to keep all of them, it's the not the most efficient but the most intuitive way is:

from collections import defaultdict
import pandas as pd

multivalue_dict = defaultdict(list)

df = pd.DataFrame({'Position':[1,2,4,4,4], 'Letter':['a', 'b', 'd', 'e', 'f']})

for idx,row in df.iterrows():
    multivalue_dict[row['Position']].append(row['Letter'])

[out]:

>>> print(multivalue_dict)
defaultdict(list, {1: ['a'], 2: ['b'], 4: ['d', 'e', 'f']})

You can use it without doing anything special. If you have a local image called blah you can do FROM blah. If you do FROM blah in your Dockerfile, but don't have a local image called blah, then Docker will try to pull it from the registry.

In other words, if a Dockerfile does FROM ubuntu, but you have a local image called ubuntu different from the official one, your image will override it.

EDIT: as of Java8 you'd better use Files class:

Path resultingPath = Files.createDirectories('A/B');

I don't know if this ultimately fixes your problem but class File has method mkdirs() which fully creates the path specified by the file.

File f = new File("/A/B/");
f.mkdirs();

I find list comprehensions are generally more expressive of what I'm trying to do than map - they both get it done, but the former saves the mental load of trying to understand what could be a complex lambda expression.

There's also an interview out there somewhere (I can't find it offhand) where Guido lists lambdas and the functional functions as the thing he most regrets about accepting into Python, so you could make the argument that they're un-Pythonic by virtue of that.

Note that reversing the whole string (either with the rbegin()/rend() range constructor or with std::reverse) and comparing it with the input would perform unnecessary work.

It's sufficient to compare the first half of the string with the latter half, in reverse:

#include <string>
#include <algorithm>
#include <iostream>
int main()
{
    std::string s;
    std::cin >> s;
    if( equal(s.begin(), s.begin() + s.size()/2, s.rbegin()) )
        std::cout << "is a palindrome.\n";
    else
        std::cout << "is NOT a palindrome.\n";
}

The state should be managed in the parent component. You can transfer the open value to the child component by adding a property.

class ParentComponent extends Component {
   constructor(props) {
      super(props);
      this.state = {
        open: false
      };

      this.toggleChildMenu = this.toggleChildMenu.bind(this);
   }

   toggleChildMenu() {
      this.setState(state => ({
        open: !state.open
      }));
   }

   render() {
      return (
         <div>
           <button onClick={this.toggleChildMenu}>
              Toggle Menu from Parent
           </button>
           <ChildComponent open={this.state.open} />
         </div>
       );
    }
}

class ChildComponent extends Component {
    render() {
      return (
         <Drawer open={this.props.open}/>
      );
    }
}

To give the second rule higher specificity you can always use parts of the first rule. In this case I would add table.rule1 trfrom rule one and add it to rule two.

table.rule1 tr td {
    background-color: #ff0000;
}

table.rule1 tr td.rule2 {
    background-color: #ffff00;
}

After a while I find this gets natural, but I know some people disagree. For those people I would suggest looking into LESS or SASS.

Install Mylyn connector for GitHub from this update site, it provides great integration: you can directly import your repositories using Import > Projects from Git > GitHub. You can set the default repository folder in Preferences > Git.

Reference the System.Web dll in your model and use System.Web.Caching.Cache

    public string[] GetNames()
    {
      string[] names = Cache["names"] as string[];
      if(names == null) //not in cache
      {
        names = DB.GetNames();
        Cache["names"] = names;
      }
      return names;
    }

A bit simplified but I guess that would work. This is not MVC specific and I have always used this method for caching data.

You should stop the task that you have scheduled on the timer: Your timer:

Timer t = new Timer();
TimerTask tt = new TimerTask() {
    @Override
    public void run() {
        //do something
    };
}
t.schedule(tt,1000,1000);

In order to stop:

tt.cancel();
t.cancel(); //In order to gracefully terminate the timer thread

Notice that just cancelling the timer will not terminate ongoing timertasks.

I improved/fixed my extension method.

public  static class ControlsExtensions
{
    public static void ClearControls(this Control frm)
    {
        foreach (Control control in frm.Controls)
        {
            if (control is TextBox)
            {
                control.ResetText();
            }

            if (control.Controls.Count > 0)
            {
                control.ClearControls();
            }
        }
    }
}

The only thing that appears to work is to set flex-wrap: wrap; on the container and them somehow make the child you want to break out after to fill the full width, so width: 100%; should work.

If, however, you can't stretch the element to 100% (for example, if it's an <img>), you can apply a margin to it, like width: 50px; margin-right: calc(100% - 50px).

Try Using JOptionPane or Swt Shell .

Quoting http://php.net/manual/en/intro.mssql.php:

The MSSQL extension is not available anymore on Windows with PHP 5.3 or later. SQLSRV, an alternative driver for MS SQL is available from Microsoft: » http://msdn.microsoft.com/en-us/sqlserver/ff657782.aspx.

Once you downloaded that, follow the instructions at this page:

• Loading the Microsoft Drivers for PHP for SQL Server

In a nutshell:

Put the driver file in your PHP extension directory.
Modify the php.ini file to include the driver. For example:

extension=php_sqlsrv_53_nts_vc9.dll  

Restart the Web server.

See Also (copied from that page)

• System Requirements (Microsoft Drivers for PHP for SQL Server)
• Getting Started
• Programming Guide
• SQLSRV Driver API Reference (Microsoft Drivers for PHP for SQL Server)

The PHP Manual for the SQLSRV extension is located at http://php.net/manual/en/sqlsrv.installation.php and offers the following for Installation:

The SQLSRV extension is enabled by adding appropriate DLL file to your PHP extension directory and the corresponding entry to the php.ini file. The SQLSRV download comes with several driver files. Which driver file you use will depend on 3 factors: the PHP version you are using, whether you are using thread-safe or non-thread-safe PHP, and whether your PHP installation was compiled with the VC6 or VC9 compiler. For example, if you are running PHP 5.3, you are using non-thread-safe PHP, and your PHP installation was compiled with the VC9 compiler, you should use the php_sqlsrv_53_nts_vc9.dll file. (You should use a non-thread-safe version compiled with the VC9 compiler if you are using IIS as your web server). If you are running PHP 5.2, you are using thread-safe PHP, and your PHP installation was compiled with the VC6 compiler, you should use the php_sqlsrv_52_ts_vc6.dll file.

The drivers can also be used with PDO.

I had the same issue/error message just after upgrading Visual Studio Pro 2019 V16.6.0. Solution was to make sure that the signing certificate is valid as mine had expired by a day.

Look in properties and signing to either enter a valid or temporary certificate. To keep the file name the same as before then un-click the security as mentioned above and then delete the key file linked to the programme.

Create a new key file and then add back the security.

If you want to modify an older commit, not the last one, you will need to use rebase command as explained in here,Github help page , on the Amending the message of older or multiple commit messages section

• Install msysgit
• Right-click on any file
• Select "Select Git Bash here" from menu
• Run ssh-keygen command from a git bash terminal

You simply pass the FormControl an array of validators.

Here's an example showing how you can add validators to an existing FormControl:

this.form.controls["firstName"].setValidators([Validators.minLength(1), Validators.maxLength(30)]);

Note, this will reset any existing validators you added when you created the FormControl.

If you're running your script in a virtual environment, say venv, then executing which python while working on venv will display the path to the Python interpreter:

~/Envs/venv/bin/python

Note that the name of the virtual environment is embedded in the path to the Python interpreter. Therefore, hardcoding this path in your script will cause two problems:

• If you upload the script to a repository, you're forcing other users to have the same virtual environment name. This is if they identify the problem first.
• You won't be able to run the script across multiple virtual environments even if you had all required packages in other virtual environments.

Therefore, to add to Jonathan's answer, the ideal shebang is #!/usr/bin/env python, not just for portability across OSes but for portability across virtual environments as well!

This will find the index of the N'th smallest or largest value in the input numeric vector x. Set bottom=TRUE in the arguments if you want the N'th from the bottom, or bottom=FALSE if you want the N'th from the top. N=1 and bottom=TRUE is equivalent to which.min, N=1 and bottom=FALSE is equivalent to which.max.

FindIndicesBottomTopN <- function(x=c(4,-2,5,-77,99),N=1,bottom=FALSE)
{

  k1 <- rank(x)
  if(bottom==TRUE){
    Nindex <- which(k1==N)
    Nindex <- Nindex[1]
  }

  if(bottom==FALSE){
    Nindex <- which(k1==(length(x)+1-N))
    Nindex <- Nindex[1]
  }

  return(Nindex)
}

Also see individual streams/filters.

E.g tail only your application logs

heroku logs --source app -t

Or see only the router logs

heroku logs --ps router

Or chain them together

heroku logs --source app --ps worker

So good..

I'll suggest using unlessand blank to check is empty or not.

Example :

unless a.blank?
  a = "Is not empty"
end

This will know 'a' empty or not. If 'a' is blank then the below code will not run.

It turns out that lstlisting is able to format code nicely, but requires a lot of tweaking.

Wikibooks has a good example for the parameters you can tweak.

I just want to echo sam9046's modest comment as an alternative and potentially much easier solution that worked in my case: uninstall and install homebrew again from scratch. No sudo commands required.

You can also browse/modify the uninstall script from that link above if you need to ensure it won't affect your previously installed packages. In my case this was just my home machine so I just started over.

d.setHours(0,0,0,0);

will do the trick

As mentioned in other answers, test.only merely filters out other tests in the same file. So tests in other files would still run.

So to run a single test, there are two approaches:

• Option 1: If your test name is unique, you can enter t while in watch mode and enter the name of the test you'd like to run.

• Option 2:

  1. Hit p while in watch mode to enter a regex for the filename you'd like to run. (Relevant commands like this are displayed when you run Jest in watch mode).
  2. Change it to it.only on the test you'd like to run.

With either of the approaches above, Jest will only run the single test in the file you've specified.

Use the % operator with a string:

irb(main):001:0> "%03d" % 5
=> "005"

The left-hand-side is a printf format string, and the right-hand side can be a list of values, so you could do something like:

irb(main):002:0> filename = "%s/%s.%04d.txt" % ["dirname", "filename", 23]
=> "dirname/filename.0023.txt"

Here's a printf format cheat sheet you might find useful in forming your format string. The printf format is originally from the C function printf, but similar formating functions are available in perl, ruby, python, java, php, etc.

Our folder structure:

/myproject
  project_using_ptdraft/
    main.py
  ptdraft/
    __init__.py
    nib.py
    simulations/
      __init__.py
      life/
        __init__.py
        life.py

The way I understand this is to have a package-centric view. The package root is ptdraft, since it's the top most level that contains __init__.py

All the files within the package can use absolute paths (that are relative to package root) for imports, for example in life.py, we have simply:

import ptdraft.nib

However, to run life.py for package dev/testing purposes, instead of python life.py, we need to use:

cd /myproject
python -m ptdraft.simulations.life.life

Note that we didn't need to fiddle with any path at all at this point.

Further confusion is when we complete the ptdraft package, and we want to use it in a driver script, which is necessarily outside of the ptdraft package folder, aka project_using_ptdraft/main.py, we would need to fiddle with paths:

import sys
sys.path.append("/myproject")  # folder that contains ptdraft
import ptdraft
import ptdraft.simulations

and use python main.py to run the script without problem.

You can also test them as a couple.

I cheated and used combination of multiple answers submitted by other people. I think this is pretty clear and straight forward piece of code. ip_validation should return True or False. Also this answer only works for IPv4 addresses

import re
ip_match = re.match('^' + '[\.]'.join(['(\d{1,3})']*4) + '$', ip_input)
ip_validate = bool(ip_match)
if ip_validate:
    ip_validate &= all(map(lambda n: 0 <= int(n) <= 255, ip_match.groups())

Connection object is for illustration only. The DataAdapter is the key bit:

Dim strSql As String = "SELECT EmpCode,EmpID,EmpName FROM dbo.Employee"
Dim dtb As New DataTable
Using cnn As New SqlConnection(connectionString)
  cnn.Open()
  Using dad As New SqlDataAdapter(strSql, cnn)
    dad.Fill(dtb)
  End Using
  cnn.Close()
End Using

morewry's solution of using transform:translateZ(0) works, actually, any transformation works, including translate(0,0) and scale(1), but if you must update the element again, then the trick is to toggle the transformation, and the best way is to directly remove it, after one frame, using requestAnimationFrame (setTimeout should always be avoided because it will be slower so it can cause glitches).

So, the update one element:

    function refresh_element(node) {
        // you can use scale(1) or translate(0, 0), etc
        node.style.setProperty('transform', 'translateZ(0)');
        // this will remove the property 1 frame later
        requestAnimationFrame(() => {
            node.style.removeProperty('transform');
        });
    }

Do not use more than one style attribute. Just seperate styles in the style attribute with ; It is a block of inline CSS, so think of this as you would do CSS in a separate stylesheet.

So in this case its: style="height:100px;width:100px;"

You can use this for any CSS style, so if you wanted to change the colour of the text to white: style="height:100px;width:100px;color:#ffffff" and so on.

However, it is worth using inline CSS sparingly, as it can make code less manageable in future. Using an external stylesheet may be a better option for this. It depends really on your requirements. Inline CSS does make for quicker coding.

There is no forumula, as street names and cities are essentially handed out randomly. The address needs to be looked up in a database. Alternatively, you can look up a zip code in a database for the region that the zip code is for.

You didn't mention a country, so I'm going to assume you just want addresses in the USA. There are numerous databases you can use, some free, some not.

You can also use the Google Maps API to have them look up an address in their database for you. That is probably the easiest solution, but requires your application to have a working internet connection at all times.

In your Http/Kernel.php

try to comment this line :

\Illuminate\Session\Middleware\AuthenticateSession::class,

Although the question is about GitHub flavored Markdown, I think it's worth mentioning that as of 2013, GitHub supports AsciiDoc which has this feature builtin. You only need to rename your file with a .adoc extension and use:

A statement.footnote:[Clarification about this statement.]

A bold statement!footnote:disclaimer[Opinions are my own.]

Another bold statement.footnote:disclaimer[]

Here is a better solution which does not clip and/or blur the drawable, but only works if the checkbox doesn't have text itself (but you can still have text, it's just more complicated, see at the end).

<CheckBox
    android:id="@+id/item_switch"
    android:layout_width="160dp"    <!-- This is the size you want -->
    android:layout_height="160dp"
    android:button="@null"
    android:background="?android:attr/listChoiceIndicatorMultiple"/>

The result:

What the previous solution with scaleX and scaleY looked like:

You can have a text checkbox by adding a TextView beside it and adding a click listener on the parent layout, then triggering the checkbox programmatically.

Make sure you pass a proxy attribute in your command forexample - pip install --proxy=http://proxyhost:proxyport pixiedust

Use a proxy port which has direct connection (with / without password). Speak with your corporate IT administrator. Quick way is find out network settings used in eclipse which will have direct connection.

You will encouter this issue often if you work behind a corporate firewall. You will have to check your internet explorer - InternetOptions -LAN Connection - Settings

Uncheck - Use automatic configuration script Check - Use a proxy server for your LAN. Ensure you have given the right address and port.

In PrimeFaces 3.0, that style get applied on the generated inner <div> of the table cell, not on the <td> as you (and I) would expect. The following example should work out for you:

<p:dataTable styleClass="myTable">

with

.myTable td:nth-child(1) {
    width: 20px;
}

In PrimeFaces 3.5 and above, it should work exactly the way you coded and expected.

Improving the lovasoa's very good answer.

If you are using python 3.6+, you can use:
pip install marshmallow-enum and
pip install marshmallow-dataclass

Its simple and type safe.

You can transform your class in a string-json and vice-versa:

From Object to String Json:

    from marshmallow_dataclass import dataclass
    user = User("Danilo","50","RedBull",15,OrderStatus.CREATED)
    user_json = User.Schema().dumps(user)
    user_json_str = user_json.data

From String Json to Object:

    json_str = '{"name":"Danilo", "orderId":"50", "productName":"RedBull", "quantity":15, "status":"Created"}'
    user, err = User.Schema().loads(json_str)
    print(user,flush=True)

Class definitions:

class OrderStatus(Enum):
    CREATED = 'Created'
    PENDING = 'Pending'
    CONFIRMED = 'Confirmed'
    FAILED = 'Failed'

@dataclass
class User:
    def __init__(self, name, orderId, productName, quantity, status):
        self.name = name
        self.orderId = orderId
        self.productName = productName
        self.quantity = quantity
        self.status = status

    name: str
    orderId: str
    productName: str
    quantity: int
    status: OrderStatus

var string = string.split(",");

This method is no longer recommended. fs.exists is deprecated. See comments.

Here are some options:

1) Have 2 "fs" calls. The first one is the "fs.exists" call, and the second is "fs.write / read, etc"

//checks if the file exists. 
//If it does, it just calls back.
//If it doesn't, then the file is created.
function checkForFile(fileName,callback)
{
    fs.exists(fileName, function (exists) {
        if(exists)
        {
            callback();
        }else
        {
            fs.writeFile(fileName, {flag: 'wx'}, function (err, data) 
            { 
                callback();
            })
        }
    });
}

function writeToFile()
{
    checkForFile("file.dat",function()
    {
       //It is now safe to write/read to file.dat
       fs.readFile("file.dat", function (err,data) 
       {
          //do stuff
       });
    });
}

2) Or Create an empty file first:

--- Sync:

//If you want to force the file to be empty then you want to use the 'w' flag:

var fd = fs.openSync(filepath, 'w');

//That will truncate the file if it exists and create it if it doesn't.

//Wrap it in an fs.closeSync call if you don't need the file descriptor it returns.

fs.closeSync(fs.openSync(filepath, 'w'));

--- ASync:

var fs = require("fs");
fs.open(path, "wx", function (err, fd) {
    // handle error
    fs.close(fd, function (err) {
        // handle error
    });
});

3) Or use "touch": https://github.com/isaacs/node-touch

You will have to pass one of the valid Identity values like DN, domain\user etc to the Set-Mailbox cmdlet. Currently you are not passing anything.

Literally you can't do such a thing, but you should try this CSS trick:

box-shadow: inset 0 3vw 6vw rgba(0,0,0,0.6), inset 0 -3vw 6vw rgba(0,0,0,0.6);

Simplest solution would be -

$('.selectpicker').trigger('change');

Try with:

@NgModule({
  imports: [
      BrowserModule,
      RouterModule.forRoot(appRoutes),
      FormsModule               
  ],
  declarations: [
      AppComponent,  
      DashboardComponent      
  ],
  bootstrap: [AppComponent]
})
export class AppModule { }

There is no need to configure the exports in AppModule, because AppModule wont be imported by other modules in your application.

def count_letter(word, char):
    count = 0
    for char in word:
        if char == word:
            count += 1
    return count        #Your return is inside your for loop
r = count_word("banana", "a")
print r

I guess an img tag is needed as a child of an a tag, the following way:

<a download="YourFileName.jpeg" href="data:image/jpeg;base64,iVBO...CYII=">
    <img src="data:image/jpeg;base64,iVBO...CYII="></img>
</a>

or

<a download="YourFileName.jpeg" href="/path/to/OtherFile.jpg">
    <img src="/path/to/OtherFile.jpg"></img>
</a>

Only using the a tag as explained in #15 didn't worked for me with the latest version of Firefox and Chrome, but putting the same image data in both a.href and img.src tags worked for me.

From JavaScript it could be generated like this:

var data = canvas.toDataURL("image/jpeg");

var img = document.createElement('img');
img.src = data;

var a = document.createElement('a');
a.setAttribute("download", "YourFileName.jpeg");
a.setAttribute("href", data);
a.appendChild(img);

var w = open();
w.document.title = 'Export Image';
w.document.body.innerHTML = 'Left-click on the image to save it.';
w.document.body.appendChild(a);

Maybe it's an unpopular answer, but in the past I've simply used a class that has a static reference to the object I want to persist through activities. So,

public class PersonHelper
{
    public static Person person;
}

I tried going down the Parcelable interface path, but ran into a number of issues with it and the overhead in your code was unappealing to me.

Source: https://developers.google.com/youtube/iframe_api_reference

   <div id="player"></div>
    <script>

          var tag = document.createElement('script');
          tag.src = "https://www.youtube.com/iframe_api";
          var firstScriptTag = document.getElementsByTagName('script')[0];
          firstScriptTag.parentNode.insertBefore(tag, firstScriptTag);

          var player;
          function onYouTubeIframeAPIReady() {
            player = new YT.Player('player', {
              height: '720',
              width: '1280',
              videoId: 'M7lc1UVf-VE',
              playerVars :{'autoplay':1,'loop':1,'playlist':'M7lc1UVf-VE','vq':'hd720'},
              events: {
                'onReady': onPlayerReady,
                'onStateChange': onPlayerStateChange
              }
            });
          }

          function onPlayerReady(event) {
               event.target.setVolume(0);
           event.target.playVideo();
          }

          var done = false;
          function onPlayerStateChange(event) {
            if (event.data == YT.PlayerState.PLAYING && !done) {
        //      setTimeout(stopVideo, 6000);
                      done = true;
            }
               event.target.setVolume(0);
          }
    </script>

I had the same problem and solved it like this:

final YourType[] yourArray = ...;
return new Iterable<YourType>() {
  public Iterator<YourType> iterator() {
     return Iterators.forArray(yourArray);   // Iterators is a Google guava utility
  }
}

The iterator itself is a lazy UnmodifiableIterator but that's exactly what I needed.

1) Find out where java is installed on your drive, open a cmd prompt, go to that location and run ".\java -version" to find out the exact version. Or, quite simply, check the add/remove module in the control panel.

2) After you actually install jdk 7, you need to tell Eclipse about it. Window -> Preferences -> Java -> Installed JREs.

Just start it with a slash? This means root. As long as you're testing on a web server (e.g. localhost) and not a file system (e.g. C:) then that should be all you need to do.

Almost NO chance to use photo or gallery application(might exist one), but you can try the content-viewer.

            foreach (ManagementObject queryObj in searcher.Get())
            {
                Console.WriteLine("-----------------------------------");
                Console.WriteLine("Win32_ComputerSystem instance");
                Console.WriteLine("-----------------------------------");
                Console.WriteLine("Name: {0}", queryObj["Name"]);
            }
        }
        catch (ManagementException e)

Please find below example to load image using JavaFX.

    import javafx.application.Application;
    import javafx.scene.Scene;
    import javafx.scene.image.Image;
    import javafx.scene.image.ImageView;
    import javafx.scene.layout.StackPane;
    import javafx.stage.Stage;

    public class LoadImage extends Application {

    public static void main(String[] args) {
    Application.launch(args);
    }
    @Override
    public void start(Stage primaryStage) {
    primaryStage.setTitle("Load Image");

    StackPane sp = new StackPane();
    Image img = new Image("javafx.jpg");
    ImageView imgView = new ImageView(img);
    sp.getChildren().add(imgView);

    //Adding HBox to the scene
    Scene scene = new Scene(sp);
    primaryStage.setScene(scene);
    primaryStage.show();
    }

  }

Create one source folder with name Image in your project and add your image to that folder otherwise you can directly load image from external URL like following.

Image img = new Image("http://mikecann.co.uk/wp-content/uploads/2009/12/javafx_logo_color_1.jpg");

You need to use the val() function to get the textbox value. text does not exist as a property only as a function and even then its not the correct function to use in this situation.

var from = $("input#fromAddress").val()

val() is the standard function for getting the value of an input.

I did this plunker to explore one way to do what you want.

Here I get mystyle from the parent component but you can get it from a service.

import {Component, View} from 'angular2/angular2'

@Component({
  selector: '[my-person]',
  inputs: [
    'name',
    'mystyle: customstyle'
  ],
  host: {
    '[style.backgroundColor]': 'mystyle.backgroundColor'
  }
})
@View({
  template: `My Person Component: {{ name }}`
})
export class Person {}

I mostly use this function:

cf() {
  cd "$(osascript -e 'tell app "Finder" to POSIX path of (insertion location as alias)')"
}

You could also assign a shortcut to a script like the ones below.

Reuse an existing tab or create a new window (Terminal):

tell application "Finder" to set p to POSIX path of (insertion location as alias)
tell application "Terminal"
    if (exists window 1) and not busy of window 1 then
        do script "cd " & quoted form of p in window 1
    else
        do script "cd " & quoted form of p
    end if
    activate
end tell

Reuse an existing tab or create a new tab (Terminal):

tell application "Finder" to set p to POSIX path of (insertion location as alias)
tell application "Terminal"
    if not (exists window 1) then reopen
    activate
    if busy of window 1 then
        tell application "System Events" to keystroke "t" using command down
    end if
    do script "cd " & quoted form of p in window 1
end tell

Always create a new tab (iTerm 2):

tell application "Finder" to set p to POSIX path of (insertion location as alias)
tell application "iTerm"
    if exists current terminal then
        current terminal
    else
        make new terminal
    end if
    tell (launch session "Default") of result to write text "cd " & quoted form of p
    activate
end tell

The first two scripts have two advantages compared to the services added in 10.7:

• They use the folder on the title bar instead of requiring you to select a folder first.
• They reuse the frontmost tab if it is not busy, e.g. running a command, displaying a man page, or running emacs.

I have the same need for downloading images using requests. I first tried the answer of Martijn Pieters, and it works well. But when I did a profile on this simple function, I found that it uses so many function calls compared to urllib and urllib2.

I then tried the way recommended by the author of requests module:

import requests
from PIL import Image
# python2.x, use this instead  
# from StringIO import StringIO
# for python3.x,
from io import StringIO

r = requests.get('https://example.com/image.jpg')
i = Image.open(StringIO(r.content))

This much more reduced the number of function calls, thus speeded up my application. Here is the code of my profiler and the result.

#!/usr/bin/python
import requests
from StringIO import StringIO
from PIL import Image
import profile

def testRequest():
    image_name = 'test1.jpg'
    url = 'http://example.com/image.jpg'

    r = requests.get(url, stream=True)
    with open(image_name, 'wb') as f:
        for chunk in r.iter_content():
            f.write(chunk)

def testRequest2():
    image_name = 'test2.jpg'
    url = 'http://example.com/image.jpg'

    r = requests.get(url)

    i = Image.open(StringIO(r.content))
    i.save(image_name)

if __name__ == '__main__':
    profile.run('testUrllib()')
    profile.run('testUrllib2()')
    profile.run('testRequest()')

The result for testRequest:

343080 function calls (343068 primitive calls) in 2.580 seconds

And the result for testRequest2:

3129 function calls (3105 primitive calls) in 0.024 seconds

I need to know way for converting uri to string and string to uri.

Use toString() to convert a Uri to a String. Use Uri.parse() to convert a String to a Uri.

this code doesn't work

That is not a valid string representation of a Uri. A Uri has a scheme, and "/external/images/media/470939" does not have a scheme.

You can't have two elements with the same ID.

Aside from that, you are defining them as block elemnts, meaning (in layman's terms) that they are being forced to appear on their own line.

Instead, try something like this:

<div class="link"><a href="..."><img src="..."... /></a></div>
<div class="link"><a href="..."><img src="..."... /></a></div>

CSS:

.link {
    width: 50%;
    float: left;
    text-align: center;
}

You could have a redirect servlet. In you web.xml you'd have:

<servlet>
    <servlet-name>images</servlet-name>
    <servlet-class>com.example.images.ImageServlet</servlet-class>
</servlet>
<servlet-mapping>
    <servlet-name>images</servlet-name>
    <url-pattern>/images/*</url-pattern>
</servlet-mapping>

All your images would be in "/images", which would be intercepted by the servlet. It would then read in the relevant file in whatever folder and serve it right back out. For example, say you have a gif in your images folder, c:\Server_Images\smilie.gif. In the web page would be <img src="http:/example.com/app/images/smilie.gif".... In the servlet, HttpServletRequest.getPathInfo() would yield "/smilie.gif". Which the servlet would find in the folder.

vs2015 no enable nuget restore problem. My solution:

1. add folder .nuget, add file NuGet.Config and NuGet.targets in Directory .nuget

2. each project file add: build

  <RestorePackages>true</RestorePackages>

  <Import Project="$(SolutionDir)\.nuget\NuGet.targets" Condition="Exists('$(SolutionDir)\.nuget\NuGet.targets')" />
  <Target Name="EnsureNuGetPackageBuildImports" BeforeTargets="PrepareForBuild">
    <PropertyGroup>
      <ErrorText>This project references NuGet package(s) that are missing on this computer. Enable NuGet Package Restore to download them.  For more information, see http://go.microsoft.com/fwlink/?LinkID=322105. The missing file is {0}.</ErrorText>
    </PropertyGroup>
    <Error Condition="!Exists('$(SolutionDir)\.nuget\NuGet.targets')" Text="$([System.String]::Format('$(ErrorText)', '$(SolutionDir)\.nuget\NuGet.targets'))" />
  </Target>

You can use a custom style:

  <!-- Alert Dialog -->
  <style name="ThemeOverlay.MaterialComponents.MaterialAlertDialog_Background" parent="@style/ThemeOverlay.MaterialComponents.MaterialAlertDialog">
    <!-- Background Color-->
    <item name="android:background">@color/.....</item>
    <!-- Text Color for title and message -->
    <item name="colorOnSurface">@color/......</item>
    <!-- Style for positive button -->
    <item name="buttonBarPositiveButtonStyle">@style/PositiveButtonStyle</item>
    <!-- Style for negative button -->
    <item name="buttonBarNegativeButtonStyle">@style/NegativeButtonStyle</item>
  </style>

  <style name="PositiveButtonStyle" parent="@style/Widget.MaterialComponents.Button">
    <!-- text color for the button -->
    <item name="android:textColor">@color/.....</item>
    <!-- Background tint for the button -->
    <item name="backgroundTint">@color/primaryDarkColor</item>
  </style>

And just use the default MaterialAlertDialogBuilder:

    new MaterialAlertDialogBuilder(AlertDialogActivity.this,
        R.style.ThemeOverlay_MaterialComponents_MaterialAlertDialog_Background)
        .setTitle("Dialog")
        .setMessage("Message...  ....")
        .setPositiveButton("Ok", /* listener = */ null)
        .show();

The discussion here gives the answer:

Actually, the specific discussion I witnessed did in fact hinge over functional purity. In an expression, there are frequently assumptions made about not having side-effects. Having ForEach is specifically inviting side-effects rather than just putting up with them. -- Keith Farmer (Partner)

Basically the decision was made to keep the extension methods functionally "pure". A ForEach would encourage side-effects when using the Enumerable extension methods, which was not the intent.

To get the size of the directory hdfs dfs -du -s -h /$yourDirectoryName can be used. hdfs dfsadmin -report can be used to see a quick cluster level storage report.

And if you neither want to use @Autowire nor injecting @Value you can simply do (with fallback included):

System.getProperty("spring.profiles.active", "unknown");

This will return any active profile (or fallback to 'unknown').

I found the docs for the get api to be helpful - especially the two sections, Source filtering and Fields: https://www.elastic.co/guide/en/elasticsearch/reference/7.3/docs-get.html#get-source-filtering

They state about source filtering:

If you only need one or two fields from the complete _source, you can use the _source_include & _source_exclude parameters to include or filter out that parts you need. This can be especially helpful with large documents where partial retrieval can save on network overhead

Which fitted my use case perfectly. I ended up simply filtering the source like so (using the shorthand):

{
    "_source": ["field_x", ..., "field_y"],
    "query": {      
        ...
    }
}

FYI, they state in the docs about the fields parameter:

The get operation allows specifying a set of stored fields that will be returned by passing the fields parameter.

It seems to cater for fields that have been specifically stored, where it places each field in an array. If the specified fields haven't been stored it will fetch each one from the _source, which could result in 'slower' retrievals. I also had trouble trying to get it to return fields of type object.

So in summary, you have two options, either though source filtering or [stored] fields.

Here's a nice answer from the FAQ on the scipy.org website:

What advantages do NumPy arrays offer over (nested) Python lists?

Python’s lists are efficient general-purpose containers. They support (fairly) efficient insertion, deletion, appending, and concatenation, and Python’s list comprehensions make them easy to construct and manipulate. However, they have certain limitations: they don’t support “vectorized” operations like elementwise addition and multiplication, and the fact that they can contain objects of differing types mean that Python must store type information for every element, and must execute type dispatching code when operating on each element. This also means that very few list operations can be carried out by efficient C loops – each iteration would require type checks and other Python API bookkeeping.

first convert your date string to date then convert it to timestamp by using following set of line

Date date=new Date();
Timestamp timestamp = new Timestamp(date.getTime());//instead of date put your converted date
Timestamp myTimeStamp= timestamp;

            $result             = ($oldNumber / $newNumber) * 100;
            $result             = abs($result);

For numerical addressing of cells try to enable S1O1 checkbox in MS Excel settings. It is the second tab from top (i.e. Formulas), somewhere mid-page in my Hungarian version.

If enabled, it handles VBA addressing in both styles, i.e. Range("A1:B10") and Range(Cells(1, 1), Cells(10, 2)). I assume it handles Range("A1:B10") style only, if not enabled.

Good luck!

(Note, that Range("A1:B10") represents a 2x10 square, while Range(Cells(1, 1), Cells(10, 2)) represents 10x2. Using column numbers instead of letters will not affect the order of addresing.)

Substr() normally (i.e. PHP and Perl) works this way:

s = Substr(s, beginning, LENGTH)

So the parameters are beginning and LENGTH.

But Python's behaviour is different; it expects beginning and one after END (!). This is difficult to spot by beginners. So the correct replacement for Substr(s, beginning, LENGTH) is

s = s[ beginning : beginning + LENGTH]

Yes, according to HTML5 drafts you can use the pattern attribute to specify the allowed input using a regular expression. For some types of data, you can use special input fields like <input type=email>. But these features still widely lack support or have qualitatively poor support.

You can simply do this:

user.js

class User {
    //...
}

module.exports = User

server.js

const User = require('./user.js')

// Instantiate User:
let user = new User()

This is called CommonJS module.

Export multiple values

Sometimes it could be useful to export more than one value. For example it could be classes, functions or constants. This is an alternative version of the same functionality:

user.js

class User {}

exports.User = User //  Spot the difference

server.js

const {User} = require('./user.js') //  Destructure on import

// Instantiate User:
let user = new User()

ES Modules

Since Node.js version 14 it's possible to use ES Modules with CommonJS. Read more about it in the ESM documentation.

?? Don't use globals, it creates potential conflicts with the future code.

slice() works like substring() with a few different behaviors.

Syntax: string.slice(start, stop);
Syntax: string.substring(start, stop);

What they have in common:

1. If start equals stop: returns an empty string
2. If stop is omitted: extracts characters to the end of the string
3. If either argument is greater than the string's length, the string's length will be used instead.

Distinctions of substring():

1. If start > stop, then substring will swap those 2 arguments.
2. If either argument is negative or is NaN, it is treated as if it were 0.

Distinctions of slice():

1. If start > stop, slice() will return the empty string. ("")
2. If start is negative: sets char from the end of string, exactly like substr() in Firefox. This behavior is observed in both Firefox and IE.
3. If stop is negative: sets stop to: string.length – Math.abs(stop) (original value), except bounded at 0 (thus, Math.max(0, string.length + stop)) as covered in the ECMA specification.

Mostly in Hibernate , need to add the Entity class in hibernate.cfg.xml like-

<hibernate-configuration>
  <session-factory>

    ....
    <mapping class="xxx.xxx.yourEntityName"/>
 </session-factory>
</hibernate-configuration>

Thanx to @androidbloke,
I have added some library that I know for multiple image picker in swift.
Will update list as I find new ones.
Thank You.

This is simple if you only use Selenium WebDriver, and forget the usage of Selenium-RC. I'd go like this.

WebDriver driver = new FirefoxDriver();
WebElement email = driver.findElement(By.id("email"));
email.sendKeys("[email protected]");

The reason for NullPointerException however is that your variable driver has never been started, you start FirefoxDriver in a variable wb thas is never being used.

SELECT *
FROM
  (First_query) AS ONE
LEFT OUTER JOIN
  (Second_query ) AS TWO ON ONE.First_query_ID = TWO.Second_Query_ID;

As the recent developed Web Applications are using JavaScript, jQuery, AngularJS, ReactJS etc there is a possibility that to retrieve an attribute of an element through Selenium you have to induce WebDriverWait to synchronize the WebDriver instance with the lagging Web Client i.e. the Web Browser before trying to retrieve any of the attributes.

Some examples:

• Python:

  • To retrieve any attribute form a visible element (e.g. <h1> tag) you need to use the expected_conditions as visibility_of_element_located(locator) as follows:

    attribute_value = WebDriverWait(driver, 20).until(EC.visibility_of_element_located((By.ID, "org"))).get_attribute("attribute_name")
    

  • To retrieve any attribute form an interactive element (e.g. <input> tag) you need to use the expected_conditions as element_to_be_clickable(locator) as follows:

    attribute_value = WebDriverWait(driver, 20).until(EC.element_to_be_clickable((By.ID, "org"))).get_attribute("attribute_name")
    

HTML Attributes

Below is a list of some attributes often used in HTML

Note: A complete list of all attributes for each HTML element, is listed in: HTML Attribute Reference

This worked for me

<div style="display: flex; position: absolute; width: 100%;">
  <div style="white-space: nowrap; overflow: hidden;text-overflow: ellipsis;">
    Lorem ipsum dolor sit amet, consectetur adipiscing elit. Integer nec odio. Praesent libero. Sed cursus ante dapibus diam. Sed nisi.
  </div>
</div>

Adding position:absolute to the parent container made it work.

PS: This is for anyone looking for a solution to dynamically truncating text.

EDIT: This was meant to be an answer for this question but since they are related and it could help someone on this question I shall also leave it here instead of deleting it.

Actually Opera doesn't have 5MB limit. It offers to increase limit as applications requires more. User can even choose "Unlimited storage" for a domain.

You can easily test localStorage limits/quota yourself.

In order to provide a clear and complete answer, I'm going to start from the very beginning before coming up with three possible solutions.

A brief introduction

All languages that run on top of the CLR (Common Language Runtime), such as C#, F#, and Visual Basic, work under a VM that runs higher level code than machine code, which native languages like C and C++ are compiled to. It follows that methods aren't Assembly subroutines, nor are they values, unlike JavaScript as well as most functional languages; rather, they're definitions that CLR recognizes. Thus, you cannot think to pass a method as a parameter, because methods don't produce any values themselves, as they're not expressions but statements, which are stored in the generated assemblies. At this point, you'll face delegates.

What's a delegate?

A delegate represents a handle to a method (the term handle is to be preferred over pointer as it is implementation–dependent.) As I said above, a method is not a value, hence there's a special class in CLR languages, namely Delegate, which wraps up any method.

Look at the following example:

static void MyMethod()
{
    Console.WriteLine("I was called by the Delegate special class!");
}

static void CallAnyMethod(Delegate yourMethod)
{
    yourMethod.DynamicInvoke(new object[] { /*Array of arguments to pass*/ });
}

static void Main()
{
    CallAnyMethod(MyMethod);
}

Three different solutions, the same underlying concept:

• The type–unsafe way
  Using the Delegate special class directly the same way as the example above. The drawback here is your code being type–unsafe, allowing arguments to be passed dynamically, with no constraints.

• The custom way
  Besides the Delegate special class, the concept of delegates spreads to custom delegates, which are declarations of methods preceded by the delegate keyword. They are type–checked the same as method declarations, leading to flawlessly safe code.

  Here's an example:

  delegate void PrintDelegate(string prompt);
  
  static void PrintSomewhere(PrintDelegate print, string prompt)
  {
      print(prompt);
  }
  
  static void PrintOnConsole(string prompt)
  {
      Console.WriteLine(prompt);
  }
  
  static void PrintOnScreen(string prompt)
  {
      MessageBox.Show(prompt);
  }
  
  static void Main()
  {
      PrintSomewhere(PrintOnConsole, "Press a key to get a message");
      Console.Read();
      PrintSomewhere(PrintOnScreen, "Hello world");
  }
  

• The standard library's way
  Alternatively, you can use a delegate that's part of the .NET Standard:

  • Action wraps up a parameterless void method.
  • Action<T1> wraps up a void method with one parameter of type T1.
  • Action<T1, T2> wraps up a void method with two parameters of types T1 and T2, respectively.
  • And so forth...
  • Func<TR> wraps up a parameterless function with TR return type.
  • Func<T1, TR> wraps up a function with TR return type and with one parameter of type T1.
  • Func<T1, T2, TR> wraps up a function with TR return type and with two parameters of types T1 and T2, respectively.
  • And so forth...

  However, bear in mind that using predefined delegates like these, parameter names won't describe what they have to be passed in, nor is the delegate name meaningful on what it's supposed to do. Therefore, be cautious about when to use these delegates and refrain from using them in contexts where their purpose is not absolutely self–evident.

^{The latter solution is the one most people posted. I'm still mentioning it in my answer for the sake of completeness.}

I think you want to use

String status = "The status of my combobox is " + comboBoxTest.Text

SelectedText property from MSDN

Gets or sets the text that is selected in the editable portion of a ComboBox.

while Text property from MSDN

Gets or sets the text associated with this control.

i can handle it like that ;

svg.selectAll("rect")
    .data(zones)
    .enter()
    .append("rect")
    .attr("id", function (d) { return "zone" + d.zone; })
    .attr("class", "zone")
    .attr("x", function (d, i) {
        if (parseInt(i / (wcount)) % 2 == 0) {
            this.xcor = (i % wcount) * zoneW;
        }
        else {
            this.xcor = (zoneW * (wcount - 1)) - ((i % wcount) * zoneW);
        }

        return this.xcor;
    })

and anymore you can find x coordinate

svg.select("#zone1").on("click",function(){alert(this.xcor});

I have tested a full layout using flexbox it contains header, footer, main body with left, center and right panels and the panels can contain menu items or footer and headers that should scroll. Pretty complex

IE11 and even IE EDGE have some problems displaying the flex content but it can be overcome. I have tested it in most browsers and it seems to work.

Some fixed i have applies are IE11 height bug, Adding height:100vh and min-height:100% to the html/body. this also helps to not have to set height on container in the dom. Also make the body/html a flex container. Otherwise IE11 will compress the view.

html,body {
    display: flex;
    flex-flow:column nowrap;
    height:100vh; /* fix IE11 */
    min-height:100%; /* fix IE11 */  
}

A fix for IE EDGE that overflows the flex container: overflow:hidden on main flex container. if you remove the overflow, IE EDGE wil push the content out of the viewport instead of containing it inside the flex main container.

main{
    flex:1 1 auto;
    overflow:hidden; /* IE EDGE overflow fix */  
}

You can see my testing and example on my codepen page. I remarked the important css parts with the fixes i have applied and hope someone finds it useful.

In the R help section, as pointed out above, just disabling quoting altogether, by simply adding:

    quote = "" 

to the read.csv() worked for me.

The error, "EOF within quoted string", occurred with:

    > iproscan.53A.neg     = read.csv("interproscan.53A.neg.n.csv",

Worked without error and all lines were successfully read in.

I'm not sure why you'd be getting subscript out of range unless your sheets weren't actually called Sheet1 or Sheet2. When I rename my Sheet2 to Sheet_2, I get that same problem.

In addition, some of your code seems the wrong way about (you paste before selecting the second sheet). This code works fine for me.

Sub OneCell()
    Sheets("Sheet1").Select
    Range("A1:A3").Copy
    Sheets("Sheet2").Select
    Range("b1:b3").Select
    ActiveSheet.Paste
End Sub

If you don't want to know about what the sheets are called, you can use integer indexes as follows:

Sub OneCell()
    Sheets(1).Select
    Range("A1:A3").Copy
    Sheets(2).Select
    Range("b1:b3").Select
    ActiveSheet.Paste
End Sub

Small but IMPORTANT notices:

1. FB.getLoginStatus must be called after FB.init, otherwise it will not fire the event.

2. you can use FB.Event.subscribe('auth.statusChange', callback), but it will not fire when user is not logged in facebook.

Here is the working example with both functions

window.fbAsyncInit = function() {
    FB.Event.subscribe('auth.statusChange', function(response) {
        console.log( "FB.Event.subscribe auth.statusChange" );
        console.log( response );
    });

    FB.init({
        appId   : "YOUR APP KEY HERE",
        cookie  : true,  // enable cookies to allow the server to access
                // the session
        xfbml   : true,  // parse social plugins on this page
        version : 'v2.1', // use version 2.1
        status  : true
    });

    FB.getLoginStatus(function(response){
        console.log( "FB.getLoginStatus" );
        console.log( response );
    });

};

// Load the SDK asynchronously
(function(d, s, id) {
    var js, fjs = d.getElementsByTagName(s)[0];
    if (d.getElementById(id)) return;
    js = d.createElement(s); js.id = id;
    js.src = "//connect.facebook.net/en_US/sdk.js";
    fjs.parentNode.insertBefore(js, fjs);
}(document, 'script', 'facebook-jssdk'));

select email from mytable group by email having count(*) >1

You can also try this one.

override fun registerWith( registry: PluginRegistry) {
        GeneratedPluginRegistrant.registerWith(registry as FlutterEngine)       
    //registry.registrarFor("io.flutter.plugins.firebasemessaging.FirebaseMessagingPlugin")
    }

I think this one is far better solution than creating a new class.
