Make sure you have the prerequisite, a JVM (http://wiki.eclipse.org/Eclipse/Installation#Install_a_JVM) installed.

This will be a JRE and JDK package.

There are a number of sources which includes: http://www.oracle.com/technetwork/java/javase/downloads/index.html.

For anybody facing a similar issue at this point in time, all you need to do is update your Android Studio to the latest version

UPDATE

The answer is now obsolete. See this answer.

maven-compiler-plugin depends on the old version of ASM which does not support Java 10 (and Java 11) yet. However, it is possible to explicitly specify the right version of ASM:

<plugin>
    <groupId>org.apache.maven.plugins</groupId>
    <artifactId>maven-compiler-plugin</artifactId>
    <version>3.7.0</version>
    <configuration>
        <release>10</release>
    </configuration>
    <dependencies>
        <dependency>
            <groupId>org.ow2.asm</groupId>
            <artifactId>asm</artifactId>
            <version>6.2</version> <!-- Use newer version of ASM -->
        </dependency>
    </dependencies>
</plugin>

You can find the latest at https://search.maven.org/search?q=g:org.ow2.asm%20AND%20a:asm&core=gav

This happened to me because I was using:

app.datasource.url=jdbc:mysql://localhost/test

When I replaced url by jdbc-url then it worked:

app.datasource.jdbc-url=jdbc:mysql://localhost/test

Go to preferences(settings) : click on Build,Execution,Deployment .....then select : Instant Run ......and uncheck its topmost checkbox (i.e Disable Instant Run)

If you are seeking a way to get to the heart of the issue. Android studio contains a feature within the edit configurations panel that simplifies this possible. By clicking on the "app" tag (It is typically to the left of the top run button)

You will open the option to edit configurations. From there create an instance of the gradle option to yourself.

The core features are actually the gradle project as well as the task. Connect the task to your debug initiative.

When you run your app through this setting, Android will spit out detailed errors(That we all wish would appear more often) and these errros will point directly a what needs to be resolved.

Worked by lowering the spring boot starter parent to 1.5.13

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

The following code worked for me:

echo userInput

Quickfix

I had similar issue and I resolved it doing the following

1. Navigate to jenkins > Manage jenkins > In-process Script Approval
2. There was a pending command, which I had to approve.

Alternative 1: Disable sandbox

As this article explains in depth, groovy scripts are run in sandbox mode by default. This means that a subset of groovy methods are allowed to run without administrator approval. It's also possible to run scripts not in sandbox mode, which implies that the whole script needs to be approved by an administrator at once. This preventing users from approving each line at the time.

Running scripts without sandbox can be done by unchecking this checkbox in your project config just below your script:

Alternative 2: Disable script security

As this article explains it also possible to disable script security completely. First install the permissive script security plugin and after that change your jenkins.xml file add this argument:

-Dpermissive-script-security.enabled=true

So you jenkins.xml will look something like this:

<executable>..bin\java</executable>
<arguments>-Dpermissive-script-security.enabled=true -Xrs -Xmx4096m -Dhudson.lifecycle=hudson.lifecycle.WindowsServiceLifecycle -jar "%BASE%\jenkins.war" --httpPort=80 --webroot="%BASE%\war"</arguments>

Make sure you know what you are doing if you implement this!

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

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

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

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

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

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

ExternalCallBadRequestException and ExternalCallServerErrorException are the custom exceptions here.

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

I found some issue about that kind of error

1. Database username or password not match in the mysql or other other database. Please set application.properties like this

  

# ===============================
# = DATA SOURCE
# ===============================
# Set here configurations for the database connection
# Connection url for the database please let me know "[email protected]"
spring.datasource.url = jdbc:mysql://localhost:3306/bookstoreapiabc
# Username and secret
spring.datasource.username = root
spring.datasource.password =
# Keep the connection alive if idle for a long time (needed in production)
spring.datasource.testWhileIdle = true
spring.datasource.validationQuery = SELECT 1
# ===============================
# = JPA / HIBERNATE
# ===============================
# Use spring.jpa.properties.* for Hibernate native properties (the prefix is
# stripped before adding them to the entity manager).
# Show or not log for each sql query

# the project
spring.jpa.hibernate.ddl-auto = update
# Allows Hibernate to generate SQL optimized for a particular DBMS
spring.jpa.properties.hibernate.dialect = org.hibernate.dialect.MySQL5Dialect

Issue no 2.

Your local server has two database server and those database server conflict. this conflict like this mysql server & xampp or lampp or wamp server. Please one of the database like mysql server because xampp or lampp server automatically install mysql server on this machine

Your test requires a ServletContext: add @WebIntegrationTest

@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration(classes = AppConfig.class, loader = AnnotationConfigContextLoader.class)
@WebIntegrationTest
public class UserServiceImplIT

...or look here for other options: https://docs.spring.io/spring-boot/docs/current/reference/html/boot-features-testing.html

UPDATE In Spring Boot 1.4.x and above @WebIntegrationTest is no longer preferred. @SpringBootTest or @WebMvcTest

The normal layout for a maven multi module project is:

parent
+-- pom.xml
+-- module
    +-- pom.xml

Check that you use this layout.

Additionally:

1. the relativePath looks strange. Instead of '..'

   <relativePath>..</relativePath>
   

   try '../' instead:

   <relativePath>../</relativePath>
   

   You can also remove relativePath if you use the standard layout. This is what I always do, and on the command line I can build as well the parent (and all modules) or only a single module.

2. The module path may be wrong. In the parent you define the module as:

   <module>junitcategorizer.cutdetection</module>
   

   You must specify the name of the folder of the child module, not an artifact identifier. If junitcategorizer.cutdetection is not the name of the folder than change it accordingly.

Hope that helps..

EDIT have a look at the other post, I answered there.

This solved my issue. It was 2.10 in my POM, just updated to 2.19.1 and refresh the POM

Add to your pom :

 <plugins>
        <plugin>
          <groupId>org.apache.maven.plugins</groupId>
          <artifactId>maven-surefire-plugin</artifactId>
          <version>2.19.1</version>
        </plugin>
  </plugins>

In your error code he didn't find surefire plugin so add it

The following worked for me

import java.time.*;
import java.time.format.*;

public class Times {

  public static void main(String[] args) {
    final String dateTime = "2012-02-22T02:06:58.147Z";
    DateTimeFormatter formatter = DateTimeFormatter.ISO_INSTANT;
    final ZonedDateTime parsed = ZonedDateTime.parse(dateTime, formatter.withZone(ZoneId.of("UTC")));
    System.out.println(parsed.toLocalDateTime());
  }
}

and gave me output as

2012-02-22T02:06:58.147

Run hive in debug mode

hive -hiveconf hive.root.logger=DEBUG,console

and then execute

show tables

can find the actual problem

From stack trace:

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

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

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

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

I'd like to give my give my practice.

Use your preferred IDE, take eclipse for for example here:

1. Find an appropriate location within the exception stack
2. Set conditional breakpoint
3. Debug it
4. It will print the corrupted jar before exception

I faced the same problem but it resolved with some changes in setting.xml(.*\apache-maven-3.3.3\apache-maven-3.3.3\conf).

  <proxies>
  <proxy>
    <id>proxy</id>
    <active>true</active>
    <protocol>http</protocol>
    <host>HOSTNAME</host>
    <port>PORT</port>
  </proxy>
</proxies>

Just check the hostname and port from the IE setting -> connections -> LAN Setting -> Proxy server

Hope this will resolve your problem also :)

Well, you're getting a java.lang.NoClassDefFoundError. In your pom.xml, hibernate-core version is 3.3.2.GA and declared after hibernate-entitymanager, so it prevails. You can remove that dependency, since will be inherited version 3.6.7.Final from hibernate-entitymanager.

You're using spring-boot as parent, so no need to declare version of some dependencies, since they are managed by spring-boot.

Also, hibernate-commons-annotations is inherited from hibernate-entitymanager and hibernate-annotations is an old version of hibernate-commons-annotations, you can remove both.

Finally, your pom.xml can look like this:

Let me know if you have a problem.

I had a similar issue that was resolved by unchecking the option in java advanced security for "Use SSL 2.0 compatible ClientHello format.

I am also facing same issue in Hortonworks

At the time I restart the Ambari agents and servers then the issue has been resolved.

 systemctl stop ambari-agent 

systemctl stop ambari-server

Source :Full Article With Resolution

 systemctl start ambari-agent

systemctl start ambari-server

Goto Properties -> maven Remove the pom.xml from the activate profiles and follow the below steps.

Steps :

1. Delete the .m2 repository
2. Restart the Eclipse IDE
3. Refresh and Rebuild it

Some time this problem occur due to incompatible java version and tomcat version.Choose the compatible version of both.

You can also not specify the type parameter which seems a bit cleaner and what Spring intended when looking at the docs:

@RequestMapping(method = RequestMethod.HEAD, value = Constants.KEY )
public ResponseEntity taxonomyPackageExists( @PathVariable final String key ){
    // ...
    return new ResponseEntity(HttpStatus.NO_CONTENT);
}

This could be a issue in mvn home path in IntellijIdea IDE. For me it worked out when I set the mvn home directory correctly.

Just another cause: If you open Charles, you could also met this problem, in this case just quit Charles.

Also had 401's from Nexus. Having tried all the suggestions above and more without success I eventually found that it was a Jenkins setting that was in error.

In the Jenkins configuration for the failing project, we have a section in the 'Post Build' actions entitled 'Deploy Artifacts To Maven Repository'. This has a 'Repository ID' field which was set to the wrong value. It has to be the same as the repository ID in settings.xml for Jenkins to read the user and password fields:

 <servers>
    <server>
      <id>snapshot-repository</id>  <!-- must match this -->
      <username>deployment</username>
      <password>password</password>
    </server>
  </servers>

Retaining all questions ids with small tweak

Map<Integer, Boolean> answerMap = 
  answerList.stream()
            .collect(Collectors.toMap(Answer::getId, a -> 
                       Boolean.TRUE.equals(a.getAnswer())));

As this is one of the first topics returned in google for this error, I'll post what I did in case someone face the same issue.. I didn't want to exclude DataSourceAutoConfiguration neither use a memory database..

In my case I was setting the parameters as the other repliers said but the application.properties file was inside the wrong folder.. lol

So in case nothing like this works, check if the file is inside src/main/resources! In my case it was inside src/main/resources/static

@Bean(name = "restTemplateByPassSSL")
public RestTemplate restTemplateByPassSSL()
        throws KeyStoreException, NoSuchAlgorithmException, KeyManagementException {
    TrustStrategy acceptingTrustStrategy = (X509Certificate[] chain, String authType) -> true;
    HostnameVerifier hostnameVerifier = (s, sslSession) -> true;
    SSLContext sslContext = SSLContexts.custom().loadTrustMaterial(null, acceptingTrustStrategy).build();
    SSLConnectionSocketFactory csf = new SSLConnectionSocketFactory(sslContext, hostnameVerifier);
    CloseableHttpClient httpClient = HttpClients.custom().setSSLSocketFactory(csf).build();
    HttpComponentsClientHttpRequestFactory requestFactory = new HttpComponentsClientHttpRequestFactory();
    requestFactory.setHttpClient(httpClient);

    return new RestTemplate(requestFactory);
}

If you are sure you haven't messed the jar, then please clean the project and perform mvn clean install. This should solve the problem.

With JUnit5 and @DataJpaTest test will look like (kotlin code):

@DataJpaTest
@ExtendWith(value = [SpringExtension::class])
class ActivityJpaTest {

    @Autowired
    lateinit var entityManager: TestEntityManager

    @Autowired
    lateinit var myEntityRepository: MyEntityRepository

    @Test
    fun shouldSaveEntity() {
        // when
        val savedEntity = myEntityRepository.save(MyEntity(1, "test")

        // then 
        Assertions.assertNotNull(entityManager.find(MyEntity::class.java, savedEntity.id))
    }
}

You could use TestEntityManager from org.springframework.boot.test.autoconfigure.orm.jpa.TestEntityManager package in order to validate entity state.

Better you update your eclipse by clicking it on help >> check for updates, also you can start eclipse by entering command in command prompt eclipse -clean.
Hope this will help you.

For those who use Tomcat with Bitronix, this will fix the problem:

The error indicates that no handler could be found for your datasource 'jdbc/mydb', so you'll need to make sure your tomcat server refers to your bitronix configuration files as needed.

In case you're using btm-config.properties and resources.properties files to configure the datasource, specify these two JVM arguments in tomcat:

(if you already used them, make sure your references are correct):

• btm.root
• bitronix.tm.configuration

e.g.

-Dbtm.root="C:\Program Files\Apache Software Foundation\Tomcat 7.0.59" 
-Dbitronix.tm.configuration="C:\Program Files\Apache Software Foundation\Tomcat 7.0.59\conf\btm-config.properties" 

Now, restart your server and check the log.

Do the build job on Jenkins first without Sonar configured. Then add Sonar, and run a build job again. Should fix the problem

Hibernate tries to insert data that violate underlying database integrity contraints.

There's probably misconfiguration in hibernate persistent classes and/or mapping configuration (*.hbm.xml or annotations in persitent classes).

Maybe a property of the bean you want to save is not type-compatible with its related field in database (could explain the constraint [numbering] part).

Make sure that firefox must install on default place like ->(c:/Program Files (x86)/mozilla firefox OR c:/Program Files/mozilla firefox, note: at the time of firefox installation do not change the path so let it installing in default path) If firefox is installed on some other place then selenium show those error.

If you have set your firefox in Systems(Windows) environment variable then either remove it or update it with new firefox version path.

If you want to use Firefox in any other place then use below code:-

As FirefoxProfile is depricated we need to use FirefoxOptions as below:

New Code:

File pathBinary = new File("C:\\Program Files\\Mozilla Firefox\\firefox.exe");
FirefoxBinary firefoxBinary = new FirefoxBinary(pathBinary);   
DesiredCapabilities desired = DesiredCapabilities.firefox();
FirefoxOptions options = new FirefoxOptions();
desired.setCapability(FirefoxOptions.FIREFOX_OPTIONS, options.setBinary(firefoxBinary));

The full working code of above code is as below:

System.setProperty("webdriver.gecko.driver","D:\\Workspace\\demoproject\\src\\lib\\geckodriver.exe");
File pathBinary = new File("C:\\Program Files\\Mozilla Firefox\\firefox.exe");
FirefoxBinary firefoxBinary = new FirefoxBinary(pathBinary);   
DesiredCapabilities desired = DesiredCapabilities.firefox();
FirefoxOptions options = new FirefoxOptions();
desired.setCapability(FirefoxOptions.FIREFOX_OPTIONS, options.setBinary(firefoxBinary));
WebDriver driver = new FirefoxDriver(options);
driver.get("https://www.google.co.in/");

Download geckodriver for firefox from below URL:

https://github.com/mozilla/geckodriver/releases

Old Code which will work for old selenium jars versions

File pathBinary = new File("C:\\Program Files (x86)\\Mozilla Firefox\\firefox.exe");
FirefoxBinary firefoxBinary = new FirefoxBinary(pathBinary);
FirefoxProfile firefoxProfile = new FirefoxProfile();       
WebDriver driver = new FirefoxDriver(firefoxBinary, firefoxProfile);

Right click in console and click Terminate/Disconnect All option.

OR

Click on 'Display selected console' icon on top right corner of the console window and, choose and terminate the console which holds the port still.

For my situation, I switched the value of "fork" to false, such as <fork>false</fork>. I do not understand why, hope someone could explain to me. Thanks in advance.

The issue here is that the version of spring-web that you're using (3.1.1-RELEASE) is not compatible with the version of spring-beans that you're using (3.0.2-RELEASE). At the top of the stack you can see the NoSuchMethodError which in turn triggers the BeanFactory not initialized... exception.

The NoSuchMethodError is caused because the method invocation XmlWebApplicationContext.loadBeanDefinitions() in spring-web is trying to call XmlBeanDefinitionReader.setEnvironment() in spring-beans which doesn't exist in 3.0.2-RELEASE. It does however exist in 3.1.1-RELEASE - as setEnvironment is inherited from the parent AbstractBeanDefinitionReader.

To resolve, you'd probably be best to upgrade the spring-beans jar to 3.1.1-RELEASE. The version for this jar appears to be parameterized in your pom.xml and is controlled by the property org.springframework.version further down in the file.

this error happens if you try access un-exists property

my guess is that sorting is done by spring by property name and not by real column name. and the error indicates that, in "UserBoard" there is no property named "boardId".

bests,

Oak

This should fix the error

It looks like you added a dependency on a Paypal library but did not include that library in your project:

Caused by: java.lang.ClassNotFoundException: com.paypal.exception.SSLConfigurationException

I'm not sure which jar, but it is most likely paypal-core.jar. Try adding it under WEB-INF/lib.

It's really incredible to be oblige to erase whole .m2/repository content. I suggest to type this command (On Windows) :

mvn clean

mvn -X package > my_log_file.log

The last command enable Debug option et redirect output to a file. Open the file and search ERROR or WARNING key words. You can find this kind of expression :

WARNING disappear just because you delete POM file corrupted at the good location and maven re download it. Normally the new POM file is better.

Often debug mode give you messages with more comprehensive details.

Why I redirect log to a file : Simply because on Windows console don't have enough buffer to store all lines and often you cannot see all lines.

com.sun.mail.util.MailLogger is part of JavaMail API. It is already included in EE environment (that's why you can use it on your live server), but it is not included in SE environment.

Oracle docs:

The JavaMail API is available as an optional package for use with Java SE platform and is also included in the Java EE platform.

99% that you run your tests in SE environment which means what you have to bother about adding it manually to your classpath when running tests.

If you're using maven add the following dependency (you might want to change version):

<dependency>
    <groupId>com.sun.mail</groupId>
    <artifactId>javax.mail</artifactId>
    <version>1.6.0</version>
</dependency>

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

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

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

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

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

Use webdriverwait with ExpectedCondition in try catch block with for loop EX: for python

for i in range(4):
    try:
        element = WebDriverWait(driver, 120).until( \
                EC.presence_of_element_located((By.XPATH, 'xpath')))
        element.click()    
        break
    except StaleElementReferenceException:
        print "exception "

The shortest solution that will work with any Java version:

<profiles>
    <profile>
        <id>disable-java8-doclint</id>
        <activation>
            <jdk>[1.8,)</jdk>
        </activation>
        <properties>
            <additionalparam>-Xdoclint:none</additionalparam>
        </properties>
    </profile>
</profiles>

Just add that to your POM and you're good to go.

This is basically @ankon's answer plus @zapp's answer.

For maven-javadoc-plugin 3.0.0 users:

Replace

<additionalparam>-Xdoclint:none</additionalparam>

by

<doclint>none</doclint>

PROBLEM SOLVED

I had exactly the same error. When the remote object got binded to the rmiregistry it was attached with the loopback IP Address which will obviously fail if you try to invoke a method from a remote address. In order to fix this we need to set the java.rmi.server.hostname property to the IP address where other devices can reach your rmiregistry over the network. It doesn't work when you try to set the parameter through the JVM. It worked for me just by adding the following line to my code just before binding the object to the rmiregistry:

System.setProperty("java.rmi.server.hostname","192.168.1.2");

In this case the IP address on the local network of the PC binding the remote object on the RMI Registry is 192.168.1.2.

Try:

$ rm YOUR_PROJECT_DIR/.metadata/.plugins/org.eclipse.core.resources/.snap

I have a function which returns a CLOB and I was seeing the above error when I'd forgotten to declare the return value as an output parameter. Initially I had:

protected SimpleJdbcCall buildJdbcCall(JdbcTemplate jdbcTemplate)
{
    SimpleJdbcCall call = new SimpleJdbcCall(jdbcTemplate)
        .withSchemaName(schema)
        .withCatalogName(catalog)
        .withFunctionName(functionName)
        .withReturnValue()          
        .declareParameters(buildSqlParameters());

    return call;
}

public SqlParameter[] buildSqlParameters() {
    return new SqlParameter[]{
        new SqlParameter("p_names", Types.VARCHAR),
        new SqlParameter("p_format", Types.VARCHAR),
        new SqlParameter("p_units", Types.VARCHAR),
        new SqlParameter("p_datums", Types.VARCHAR),
        new SqlParameter("p_start", Types.VARCHAR),
        new SqlParameter("p_end", Types.VARCHAR),
        new SqlParameter("p_timezone", Types.VARCHAR),
        new SqlParameter("p_office_id", Types.VARCHAR),
        };
}

The buildSqlParameters method should have included the SqlOutParameter:

public SqlParameter[] buildSqlParameters() {
    return new SqlParameter[]{
        new SqlParameter("p_names", Types.VARCHAR),
        new SqlParameter("p_format", Types.VARCHAR),
        new SqlParameter("p_units", Types.VARCHAR),
        new SqlParameter("p_datums", Types.VARCHAR),
        new SqlParameter("p_start", Types.VARCHAR),
        new SqlParameter("p_end", Types.VARCHAR),
        new SqlParameter("p_timezone", Types.VARCHAR),
        new SqlParameter("p_office_id", Types.VARCHAR),
        new SqlOutParameter("l_clob", Types.CLOB)  // <-- This was missing!
    }; 
}

Java 7 introduced stricter verification and changed the class format a bit—to contain a stack map used to verify that code is correct. The exception you see means that some method doesn't have a valid stack map.

Java version or bytecode instrumentation could both be to blame. Usually this means that a library used by the application generates invalid bytecode that doesn't pass the stricter verification. So nothing else than reporting it as a bug to the library can be done by the developer.

As a workaround you can add -noverify to the JVM arguments in order to disable verification. In Java 7 it was also possible to use -XX:-UseSplitVerifier to use the less strict verification method, but that option was removed in Java 8.

I encountered this exception in WebLogic, turns out it is a bug in WebLogic. Please see here for more details: Spring Boot exception: Could not open ServletContext resource [/WEB-INF/dispatcherServlet-servlet.xml]

I know it's a bit old but I ran in the same problem today. I wanted to install eclipse on my vm with xubuntu. Because I've had problems with the latest eclipse version 2019-06 I tried with Oxygen. So I went to eclipse.org and downloaded oxygen. When running oxygen, the problem with merketplace not reachable occurs. So I downloaded the eclipse installer not immediatly the oxygen. After that I can use eclipse as expectet ( all versions)

I was also suffering from the same issue. Finally I resolved it by setting binary value in capabilites as shown below. At run time it uses this value so it is must to set.

DesiredCapabilities capability = DesiredCapabilities.firefox();
capability.setCapability("platform", Platform.ANY);
capability.setCapability("binary", "/ms/dist/fsf/PROJ/firefox/16.0.0/bin/firefox"); //for linux

//capability.setCapability("binary", "C:\\Program Files\\Mozilla  Firefox\\msfirefox.exe"); //for windows                
WebDriver    currentDriver = new RemoteWebDriver(new URL("http://localhost:4444/wd/hub"), capability);

And you are done!!! Happy coding :)

As Nayan said the Path has to updated properly in my case the apache-maven was installed in C:\apache-maven and settings.xml was found inside C:\apache-maven\conf\settings.xml

if this doesn't work go to your local repos
in my case C:\Users\<<"name">>.m2\
and search for .lastUpdated and delete them
then build the maven

Or

Navigate to project root folder and use following commands :

mvn clean install -U or mvn clean install --update-snapshots

Here -U will Forces a check for missing releases and updated snapshots on remote repositories

Make sure you have settings.xml. I had the same problem when I've deleted it by mistake.

I got the same error "selenium_Unable to connect to host 127.0.0.1 on port 7055" Solution : I've used selenium-java-2.48.2 with Firefox version 43.0.1 and now its working well.

I had the same issue. After much searching I decided to reconfigure my server in Eclipse. (ie clean it as suggested by Benson Go to Project Explorer, Servers and Delete (ensure you also delete contents on disk) Then go to Windows->Preferences->Server->Runtime Environments Remove the Tomcat server and then add it back in.

This cleans up the server.xml, webxml, context.xml files. It basically rewrites them. Something in one of mine (or multiple things) were awry and this fixes it. A bit simpler than trying to find the offending tags/lines

I had the same problem. To fix it in Jboss 7 AS, I copy the oracle driver jar file to Jboss module folder. Example: ../jboss-as-7.1.1.Final/modules/org/hibernate/main.

You also need to change "module.xml"

Had the same error. Removing the object from the model did the trick.

Code which shows the mistake:

void update() {
    VBox vBox = mHboxEventSelection.getVboxSelectionRows();

    Session session = HibernateUtilEventsCreate.getSessionFactory().openSession();
    session.beginTransaction();

    HashMap<String, EventLink> existingEventLinks = new HashMap<>();
    for (EventLink eventLink : mEventProperty.getEventLinks()) {
        existingEventLinks.put(eventLink.getEvent().getName(), eventLink);
    }

    mEventProperty.setName(getName());

    for (Node node : vBox.getChildren()) {

        if (node instanceof HBox) {
            JFXComboBox<EventEntity> comboBoxEvents = (JFXComboBox<EventEntity>) ((HBox) node).getChildren().get(0);
            if (comboBoxEvents.getSelectionModel().getSelectedIndex() == -1) {
                Log.w(TAG, "update: Invalid eventEntity collection");
            }

            EventEntity eventEntity = comboBoxEvents.getSelectionModel().getSelectedItem();
            Log.v(TAG, "update(" + mCostType + "): event-id=" + eventEntity.getId() + " - " + eventEntity.getName());

            String split = ((JFXTextField) (((HBox) node).getChildren().get(1))).getText();
            if (split.isEmpty()) {
                split = "0";
            }
            if (existingEventLinks.containsKey(eventEntity.getName())) {
                // event-link did exist
                EventLink eventLink = existingEventLinks.get(eventEntity.getName());
                eventLink.setSplit(Integer.parseInt(split));
                session.update(eventLink);
                existingEventLinks.remove(eventEntity.getName(), eventLink);
            } else {
                // event-link is a new one, so create!
                EventLink link1 = new EventLink();

                link1.setProperty(mEventProperty);
                link1.setEvent(eventEntity);
                link1.setCreationTime(new Date(System.currentTimeMillis()));
                link1.setSplit(Integer.parseInt(split));

                eventEntity.getEventLinks().add(link1);
                session.saveOrUpdate(eventEntity);
            }

        }
    }

    for (Map.Entry<String, EventLink> entry : existingEventLinks.entrySet()) {
        Log.i(TAG, "update: will delete link=" + entry.getKey());
        EventLink val = entry.getValue();
        mEventProperty.getEventLinks().remove(val); // <- remove from model
        session.delete(val);
    }

    session.saveOrUpdate(mEventProperty);

    session.getTransaction().commit();
    session.close();
}

I just came across the same issue while trying to query a MySQL Database from Pentaho.

Error connecting to database [Local MySQL DB] : org.pentaho.di.core.exception.KettleDatabaseException: Error occured while trying to connect to the database

Exception while loading class org.gjt.mm.mysql.Driver

Expanding post by @user979331 the solution is:

1. Download the MySQL Java Connector / Driver that is compatible with your kettle version
2. Unzip the zip file (in my case it was mysql-connector-java-5.1.31.zip)

3. copy the .jar file (mysql-connector-java-5.1.31-bin.jar) and paste it in your Lib folder:

   PC: C:\Program Files\pentaho\design-tools\data-integration\lib

   Mac: /Applications/data-integration/lib

Restart Pentaho (Data Integration) and re-test the MySQL Connection.

Additional interesting replies from others that could also help:

• think to download the good JDBC driver version, compatible with your PDI version: https://help.pentaho.com/Documentation/8.1/Setup/JDBC_Drivers_Reference#MY_SQL
• take the zip version ("platform independant") to extract the jar file
• take into lib folder
• see also proper way to handle it proposed by Ryan Tuck

I encountered the same issue, when jdk 1.7 was used to compile then jre 1.4 was used for execution.

My solution was to set environment variable PATH by adding pathname C:\glassfish3\jdk7\bin in front of the existing PATH setting. The updated value is "C:\glassfish3\jdk7\bin;C:\Sun\SDK\bin". After the update, the problem was gone.

Eclipse is launching your application with whatever JRE you defined in your launch configuration. Since you're running the 32-bit Eclipse, you're running/debugging against its 32-bit SWT libraries, and you'll need to run a 32-bit JRE.

Your 64-bit JRE is, for whatever reason, your default Installed JRE.

To change this, first make sure you have a 32-bit JRE configured in the Installed JREs preference. Go to Window -> Preferences and navigate to Java -> Installed JREs:

You can click Add and navigate to your 32-bit JVM's JAVA_HOME to add it.

Then in your Run Configuration, find your Eclipse Application and make sure the Runtime JRE is set to the 32-bit JRE you just configured:

(Note the combobox that is poorly highlighted.)

Don't try replacing SWT jars, that will likely end poorly.

1 Right click on "your project" in Eclipse EE Project Explorer 2 Click on Properties 3 Click on Targeted Runtimes 4 Checkbox of the version you are currently working with 5 Apply and close

This should do the trick.

This is very weird behavior of PostgreSQL, it is even not " in-line with the PostgreSQL philosophy of forcing the user to make everything explicit" - as the exception was caught and ignored explicitly. So even this defense does not hold. Oracle in this case behaves much more user-friendly and (as for me) correctly - it leaves a choice to the developer.

use some thing like

import java.io.*;
import javax.xml.transform.*;
import javax.xml.transform.dom.*;
import javax.xml.transform.stream.*;

//method to convert Document to String
public String getStringFromDocument(Document doc)
{
    try
    {
       DOMSource domSource = new DOMSource(doc);
       StringWriter writer = new StringWriter();
       StreamResult result = new StreamResult(writer);
       TransformerFactory tf = TransformerFactory.newInstance();
       Transformer transformer = tf.newTransformer();
       transformer.transform(domSource, result);
       return writer.toString();
    }
    catch(TransformerException ex)
    {
       ex.printStackTrace();
       return null;
    }
} 

I agree with Scott, what he listed worked. However just running it from any directory did not work. I had to cd to the /home/*/.swt/lib/linux/x86_64/ 0 files

directory first and then run the link command:

For 32 bit:

ln -s /usr/lib/jni/libswt-* ~/.swt/lib/linux/x86/

And on Ubuntu 12.04 64 bit:

ln -s /usr/lib/jni/libswt-* ~/.swt/lib/linux/x86_64/

Just check tsnnames.ora and listener.ora files. It should not have localhost as a server. change it to hostname.

Like in tnsnames.ora

LISTENER_ORCL =
(ADDRESS = (PROTOCOL = TCP)(HOST = localhost)(PORT = 1521))

Replace localhost by hostname.

you can try to add these code:

VelocityEngine ve = new VelocityEngine();
String vmPath = request.getSession().getServletContext().getRealPath("${your dir}");
Properties p = new Properties();
p.setProperty("file.resource.loader.path", vmPath+"//");
ve.init(p);

I do this, and pass!

My issue was due to version conflict. I resolved this issue by excluding byte-buddy dependency from springfox

  <exclusions>

  <exclusions>
  <exclusion>
    <groupId>net.bytebuddy</groupId>
    <artifactId>byte-buddy</artifactId>
  </exclusion>
</exclusions>
</dependency>

check if the object exists or not in DB, if it exists get the object and refresh it:

if (getEntityManager().contains(instance)) {
    getEntityManager().refresh(instance);
    return instance;
}

if it fails the above if condition... find the Object with Id in DB, do the operation which you need, in this case exactly changes will reflects.

if (....) {
    } else if (null != identity) {
        E dbInstance = (E) getEntityManager().find(instance.getClass(), identity);
        return dbInstance;
    }

You change the private int pkgId line in change datatype int to primitive class name or add annotation @autowired

As @swanliu pointed out it is due to a bad connection.
However before adjusting the server timing and client timeout , I would first try and use a better connection pooling strategy.

Connection Pooling

Hibernate itself admits that its connection pooling strategy is minimal

Hibernate's own connection pooling algorithm is, however, quite rudimentary. It is intended to help you get started and is not intended for use in a production system, or even for performance testing. You should use a third party pool for best performance and stability. Just replace the hibernate.connection.pool_size property with connection pool specific settings. This will turn off Hibernate's internal pool. For example, you might like to use c3p0.
As stated in Reference : http://docs.jboss.org/hibernate/core/3.3/reference/en/html/session-configuration.html

I personally use C3P0. however there are other alternatives available including DBCP.
Check out

• http://www.mchange.com/projects/c3p0/index.html
• http://commons.apache.org/dbcp/

Below is a minimal configuration of C3P0 used in my application:

<property name="connection.provider_class">org.hibernate.connection.C3P0ConnectionProvider</property>
<property name="c3p0.acquire_increment">1</property> 
<property name="c3p0.idle_test_period">100</property> <!-- seconds --> 
<property name="c3p0.max_size">100</property> 
<property name="c3p0.max_statements">0</property> 
<property name="c3p0.min_size">10</property> 
<property name="c3p0.timeout">1800</property> <!-- seconds --> 

By default, pools will never expire Connections. If you wish Connections to be expired over time in order to maintain "freshness", set maxIdleTime and/or maxConnectionAge. maxIdleTime defines how many seconds a Connection should be permitted to go unused before being culled from the pool. maxConnectionAge forces the pool to cull any Connections that were acquired from the database more than the set number of seconds in the past.
As stated in Reference : http://www.mchange.com/projects/c3p0/index.html#managing_pool_size

Edit:
I updated the configuration file (Reference), as I had just copy pasted the one for my project earlier. The timeout should ideally solve the problem, If that doesn't work for you there is an expensive solution which I think you could have a look at:

Create a file “c3p0.properties” which must be in the root of the classpath (i.e. no way to override it for particular parts of the application). (Reference)

# c3p0.properties
c3p0.testConnectionOnCheckout=true

With this configuration each connection is tested before being used. It however might affect the performance of the site.

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.

I've seen a lot of inadequate answers while trying to figure this one out. General response has been "you are trying to stop something that hasn't started" or "some other program is running on the port you need".

The problem for me turned out to be my firewall. I hadn't even considered this, but port 8005 (the port used for shutdown, thanks mindas), was blocked. I changed it, and now, no more error. Good luck.

goto command prompt

netstat -aon

for linux

netstat -tulpn | grep 'your_port_number'

it will show you something like

check which process has binded your port. here in above example its 248 now if you are sure that you need to kill that process fire

Linux:

kill -9 248

Windows:

taskkill /f /pid 248

it will kill that process

Apparently, you did it right. But here is a list of things you'll need with examples from a working application:

1) A context.xml file in META-INF, specifying your data source:

<Context>
    <Resource 
        name="jdbc/DsWebAppDB" 
        auth="Container" 
        type="javax.sql.DataSource" 
        username="sa" 
        password="" 
        driverClassName="org.h2.Driver" 
        url="jdbc:h2:mem:target/test/db/h2/hibernate" 
        maxActive="8" 
        maxIdle="4"/>
</Context>

2) web.xml which tells the container that you are using this resource:

<resource-env-ref>
    <resource-env-ref-name>jdbc/DsWebAppDB</resource-env-ref-name>
    <resource-env-ref-type>javax.sql.DataSource</resource-env-ref-type>
</resource-env-ref>

3) Hibernate configuration which consumes the data source. In this case, it's a persistence.xml, but it's similar in hibernate.cfg.xml

<persistence-unit name="dswebapp">
    <provider>org.hibernate.ejb.HibernatePersistence</provider>
    <properties>
        <property name="hibernate.dialect" value="org.hibernate.dialect.H2Dialect" />
        <property name="hibernate.connection.datasource" value="java:comp/env/jdbc/DsWebAppDB"/>
    </properties>
</persistence-unit>

You're using Comparators incorrectly.

 Collections.sort(movieItems, new Comparator<Movie>(){
           public int compare (Movie m1, Movie m2){
               return m1.getDate().compareTo(m2.getDate());
           }
       });

I got the following error:

org.hibernate.HibernateException: No Hibernate Session bound to thread, and configuration does not allow creation of non-transactional one here
    at org.springframework.orm.hibernate3.SpringSessionContext.currentSession(SpringSessionContext.java:63)

I fixed this by changing my hibernate properties file

hibernate.current_session_context_class=thread

My code and configuration file as follows

session =  getHibernateTemplate().getSessionFactory().getCurrentSession();

session.beginTransaction();

session.createQuery(Qry).executeUpdate();

session.getTransaction().commit();

on properties file

hibernate.dialect=org.hibernate.dialect.MySQLDialect

hibernate.show_sql=true

hibernate.query_factory_class=org.hibernate.hql.ast.ASTQueryTranslatorFactory

hibernate.current_session_context_class=thread

on cofiguration file

<properties>
<property name="hibernateProperties">
<props>
<prop key="hibernate.dialect">${hibernate.dialect}</prop>
<prop key="hibernate.show_sql">${hibernate.show_sql}</prop>         
<prop key="hibernate.query.factory_class">${hibernate.query_factory_class}</prop>       
<prop key="hibernate.generate_statistics">true</prop>
<prop key="hibernate.current_session_context_class">${hibernate.current_session_context_class}</prop>
</props>
</property>
</properties>

Thanks,
Ashok

It's definitely not a problem with propeties file not being found, since in that case another exception is thrown.

Make sure that you actually have a value with key idm.url in your idm.properties.

I recently struggled with this issue for 3 days. How the client is sending the request might not be the cause, the server might not be configured to handle multipart requests. This is what I had to do to get it working:

pom.xml - Added commons-fileupload dependency (download and add the jar to your project if you are not using dependency management such as maven)

<dependency>
  <groupId>commons-fileupload</groupId>
  <artifactId>commons-fileupload</artifactId>
  <version>${commons-version}</version>
</dependency>

web.xml - Add multipart filter and mapping

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

app-context.xml - Add multipart resolver

<beans:bean id="multipartResolver" class="org.springframework.web.multipart.commons.CommonsMultipartResolver">
    <beans:property name="maxUploadSize">
        <beans:value>10000000</beans:value>
    </beans:property>
</beans:bean>

Your Controller

@RequestMapping(value=Constants.REQUEST_MAPPING_ADD_IMAGE, method = RequestMethod.POST, produces = { "application/json"})
public @ResponseBody boolean saveStationImage(
        @RequestParam(value = Constants.MONGO_STATION_PROFILE_IMAGE_FILE) MultipartFile file,
        @RequestParam(value = Constants.MONGO_STATION_PROFILE_IMAGE_URI) String imageUri, 
        @RequestParam(value = Constants.MONGO_STATION_PROFILE_IMAGE_TYPE) String imageType, 
        @RequestParam(value = Constants.MONGO_FIELD_STATION_ID) String stationId) {
    // Do something with file
    // Return results
}

Your client

public static Boolean updateStationImage(StationImage stationImage) {
    if(stationImage == null) {
        Log.w(TAG + ":updateStationImage", "Station Image object is null, returning.");
        return null;
    }

    Log.d(TAG, "Uploading: " + stationImage.getImageUri());
    try {
        RestTemplate restTemplate = new RestTemplate();
        FormHttpMessageConverter formConverter = new FormHttpMessageConverter();
        formConverter.setCharset(Charset.forName("UTF8"));
        restTemplate.getMessageConverters().add(formConverter);
        restTemplate.getMessageConverters().add(new MappingJackson2HttpMessageConverter());

        restTemplate.setRequestFactory(new HttpComponentsClientHttpRequestFactory());

        HttpHeaders httpHeaders = new HttpHeaders();
        httpHeaders.setAccept(Collections.singletonList(MediaType.parseMediaType("application/json")));

        MultiValueMap<String, Object> parts = new LinkedMultiValueMap<String, Object>();

        parts.add(Constants.STATION_PROFILE_IMAGE_FILE, new FileSystemResource(stationImage.getImageFile()));
        parts.add(Constants.STATION_PROFILE_IMAGE_URI, stationImage.getImageUri());
        parts.add(Constants.STATION_PROFILE_IMAGE_TYPE, stationImage.getImageType());
        parts.add(Constants.FIELD_STATION_ID, stationImage.getStationId());

        return restTemplate.postForObject(Constants.REST_CLIENT_URL_ADD_IMAGE, parts, Boolean.class);
    } catch (Exception e) {
        StringWriter sw = new StringWriter();
        e.printStackTrace(new PrintWriter(sw));

        Log.e(TAG + ":addStationImage", sw.toString());
    }

    return false;
}

That should do the trick. I added as much information as possible because I spent days, piecing together bits and pieces of the full issue, I hope this will help.

For a more graceful way, try the following:

Caveat: I'm running Debian 7, not Ubuntu, though it is a Debian derivative

If you're running Tomcat as a service, you can get a list of all running services by typing:

sudo service --status-all

I'm running Tomcat 7, which is displayed as tomcat7 in said list. Then, to shut it down just type:

sudo service tomcat7 stop

In order to resolve java.lang.OutOfMemoryError: Java heap space in Maven, try to configure below configuration in pom

<plugin>
  <groupId>org.apache.maven.plugins</groupId>
  <artifactId>maven-surefire-plugin</artifactId>
  <version>${maven-surefire-plugin.version}</version>
     <configuration>
        <verbose>true</verbose>
        <fork>true</fork>
        <argLine>-XX:MaxPermSize=500M</argLine>
    </configuration>
</plugin>

FYI, another way this exception can occur is if:

• Your transaction isolation is READ_COMMITTED
• Transaction #1 queries for an entity, then deletes that entity
• A simultaneous transaction #2 does the same thing

Then this can happen: TX #1 successfully commits before TX #2, then when TX #2 tries to delete the entity (again) it's not there any more - even though it was found by a query earlier in that same transaction. Note this anomaly is allowed with READ_COMMITTED isolation.

In my case the resulting exception looked like this:

HHH000315: Exception executing batch [org.hibernate.StaleStateException:
  Batch update returned unexpected row count from update [0]; actual row
  count: 0; expected: 1; statement executed: delete from Foobar where id=?],
  SQL: delete from Foobar where id=?

for me it worked the approach that I used in eclipselink as well. Just call the size() of the collection that should be loaded before using it as parameter to pages.

for (Entity e : entityListKeeper.getEntityList()) {
    e.getListLazyLoadedEntity().size();
}

Here entityListKeeper has List of Entity that has list of LazyLoadedEntity. If you have just therelation Entity has list of LazyLoadedEntity then the solution is:

getListLazyLoadedEntity().size();

I had the same problem, and the solution for me was to allow Maven to handle all dependencies, including to local jars. I used Maven for online dependencies, and configured build path manually for local dependencies. Thus, Maven was not aware of the dependencies I configured manually.

I used this solution to install the local jar dependencies into Maven:

How to add local jar files in maven project?

We face this error when permanent generation heap is full and some of us we use command prompt to build our maven project in windows. since we need to increase heap size, we could set our environment variable @ControlPanel/System and Security/System and there you click on Change setting and select Advanced and set Environment variable as below

• Variable-name : MAVEN_OPTS
• Variable-value : -XX:MaxPermSize=128m

Adding my two cents for those searching for "Ensure that the org.eclipse.core.runtime bundle is resolved and started":

Adding "arbitrary" bundles to the list of bundles just because it seems that they are missing is not always the best solution. Sometimes it can get quite frustrating, because those new plugins might depend on other missing bundles, which need even more bundles and so on...

So, before adding a new dependency to the list of required bundles, make sure you understand why the bundle is needed (the debugger is your friend!).

This question here doesn't provide enough information to make this a valid answer in all cases, but if you encounter the message that the org.eclipse.core.runtime is missing, try setting the eclipse.application.launchDefault system property to false, especially if you try to run an application which is not an "eclipse application" (but maybe just a headless runtime on top of equinox).

This link might come in handy: http://help.eclipse.org/indigo/index.jsp?topic=%2Forg.eclipse.platform.doc.isv%2Freference%2Fmisc%2Fruntime-options.html, look for the eclipse.application.launchDefault system property.

I change my APIs as * cglib --- to ---> cglib-nodep-2.2.jar * cglib-asm --- to ---> cglib-asm.jar (i.e. latest one )

In my mind I have to consider that the foo folder is a stand-alone library. I might want to consider moving it to the Lib\site-packages folder within a python installation. I might want to consider adding a foo.pth file there.

I know it's a library since the ./programs/my_python_program.py contains the following line:

from foo.tasks import my_function

So it doesn't matter that ./programs is a sibling folder to ./foo. It's the fact that my_python_program.py is run as a script like this:

python ./programs/my_python_program.py

SQLServer runs the default instance over port 1433. If you specify the port as port 1433, SQLServer will only look for the default instance. The name of the default instance was created at setup and usually is SQLEXPRESSxxx_xx_ENU.

The instance name also matches the folder name created in Program Files -> Microsoft SQL Server. So if you look there and see one folder named SQLEXPRESSxxx_xx_ENU it is the default instance.

Folders named MSSQL12.myInstanceName (for SQLServer 2012) are named instances in SQL Server and are not accessed via port 1433.

So if your program is accessing a default instance in the database, specify port 1433, and you may not need to specify the instance name.

If your program is accessing a named instance (not the default instance) in the database DO NOT specify the port but you must specify the instance name.

I hope this clarifies some of the confusion emanating from the errors above.

Something like this worked for me.

If your dependencies are fine (check with mvn dependency:list) like mine were, then it's a maven glitch, if you're using Eclipse do:

1. Right click the project > Maven > Update Project...
2. Check everything but Offline
3. OK

You should be good.

I don't know the equivalent mvn commands, if anyone could post them they could be useful.

I did also stumble upon this error. In my case the problem was I was using JRE6, with support for TLS1.0. The server only supported TLS1.2, so this error was thrown.

If you are managing the Hibernate session manually, you may want to look into sessionFactory.getCurrentSession() and associated docs here:

http://www.hibernate.org/hib_docs/v3/reference/en/html/architecture-current-session.html

end-of-file on communication channel:

One of the course of this error is due to database fail to write the log when its in the stage of opening;

Solution check the database if its running in ARCHIVELOG or NOARCHIVELOG

to check use

select log_mode from v$database;

if its on ARCHIVELOG try to change into NOARCHIVELOG

by using sqlplus

• startup mount
• alter database noarchivelog;
• alter database open;

if it works for this

Then you can adjust your flashrecovery area its possibly that your flashrecovery area is full -> then after confirm that your flashrecovery area has the space you can alter your database into the ARCHIVELOG

Here's what worked for me: right click the project-> source -> format After that just drag and drop the source folder into eclipse under the project and select link.

good luck!

Use Intellij plugin Sketch It!.

For example here is a element like button for adding item to basket and appropriate attributes for saving in localStorage.

'<a href="#" cartBtn pr_id='+e.id+' pr_name_en="'+e.nameEn+'" pr_price="'+e.price+'" pr_image="'+e.image+'" class="btn btn-primary"><i class="fa fa-shopping-cart"></i>Add to cart</a>'

var productArray=[];


$(document).on('click','[cartBtn]',function(e){
  e.preventDefault();
  $(this).html('<i class="fa fa-check"></i>Added to cart');
  console.log('Item added ');
  var productJSON={"id":$(this).attr('pr_id'), "nameEn":$(this).attr('pr_name_en'), "price":$(this).attr('pr_price'), "image":$(this).attr('pr_image')};


  if(localStorage.getObj('product')!==null){
    productArray=localStorage.getObj('product');
    productArray.push(productJSON);  
    localStorage.setObj('product', productArray);  
  }
  else{
    productArray.push(productJSON);  
    localStorage.setObj('product', productArray);  
  }


});

Storage.prototype.setObj = function(key, value) {
    this.setItem(key, JSON.stringify(value));
}

Storage.prototype.getObj = function(key) {
    var value = this.getItem(key);
    return value && JSON.parse(value);
}

After adding JSON object to Array result is (in LocalStorage):

[{"id":"99","nameEn":"Product Name1","price":"767","image":"1462012597217.jpeg"},{"id":"93","nameEn":"Product Name2","price":"76","image":"1461449637106.jpeg"},{"id":"94","nameEn":"Product Name3","price":"87","image":"1461449679506.jpeg"}]

after this action you can easily send data to server as List in Java

Full code example is here

How do I store a simple cart using localStorage?

TypeScript variant

const compareNumbers = (a: number, b: number): number => a - b

myArray.sort(compareNumbers)

An ambiguous case that breaks in the absence of a semicolon:

// define a function
var fn = function () {
    //...
} // semicolon missing at this line

// then execute some code inside a closure
(function () {
    //...
})();

This will be interpreted as:

var fn = function () {
    //...
}(function () {
    //...
})();

We end up passing the second function as an argument to the first function and then trying to call the result of the first function call as a function. The second function will fail with a "... is not a function" error at runtime.

what about this

--// Convert NVARCHAR to DATETIME
DECLARE @date DATETIME = (SELECT convert(DATETIME, '2013-08-29 13:55:48', 120))
--// Convert DATETIME to custom NVARCHAR FORMAT
SELECT 
RIGHT('00'+ CAST(DAY(@date) AS NVARCHAR),2) + '-' +
RIGHT('00'+ CAST(MONTH(@date) AS NVARCHAR),2) + '-' + 
CAST(YEAR(@date) AS NVARCHAR) + ' ' + 
CAST(CONVERT(TIME,@date) AS NVARCHAR)

result: '29-08-2013 13:55:48.0000000'

Recommended solution is to install and trust a self-signed certificate (root). Assuming you created your own CA and the hierarchy of the certificated is correct you don't need to change the server trust evaluation. This is recommended because it doesn't require any changes in the code.

1. Generate CA and the certificates (you can use openssl: Generating CA and self-signed certificates.
2. Install root certificate (*.cer file) on the device - you can open it by Safari and it should redirect you to Settings
3. When the certificated is installed, go to Certificate Trust Settings (Settings > General > About > Certificate Trust Settings) as in MattP answer.

If it is not possible then you need to change server trust evaluation.

Firstly you need to create AdminClient bean:

 @Bean
 public AdminClient adminClient(){
   Map<String, Object> configs = new HashMap<>();
   configs.put(AdminClientConfig.BOOTSTRAP_SERVERS_CONFIG,
   StringUtils.arrayToCommaDelimitedString(new Object[]{"your bootstrap server address}));
   return AdminClient.create(configs);
 }

Then, you can use this script:

while (true) {
   Map<String, ConsumerGroupDescription> groupDescriptionMap =
         adminClient.describeConsumerGroups(Collections.singletonList(groupId))
         .all()
         .get(10, TimeUnit.SECONDS);

   ConsumerGroupDescription consumerGroupDescription = groupDescriptionMap.get(groupId);

   log.debug("Kafka consumer group ({}) state: {}",
                groupId,
                consumerGroupDescription.state());

   if (consumerGroupDescription.state().equals(ConsumerGroupState.STABLE)) {
        boolean isReady = true;
        for (MemberDescription member : consumerGroupDescription.members()) {
            if (member.assignment() == null || member.assignment().topicPartitions().isEmpty()) {
            isReady = false;
            }
        }

        if (isReady) {
            break;
           }
        }

        log.debug("Kafka consumer group ({}) is not ready. Waiting...", groupId);
        TimeUnit.SECONDS.sleep(1);
}

This script will check the state of the consumer group every second till the state will be STABLE. Because all consumers assigned to topic partitions, you can conclude that server is running and ready.

Try

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

This is C#, but should give you the idea:

public static void Main() {
    typeof(Program).GetProperty("GetMe", BindingFlags.NonPublic | BindingFlags.Static);
}

private static int GetMe {
    get { return 0; }
}

(you need to OR NonPublic and Static only)

This would give the current date and time:

public String getCurrDate()
{
    String dt;
    Date cal = Calendar.getInstance().getTime();
    dt = cal.toLocaleString();
    return dt;
}

Per default collections in scala are immutable, so you have a + method which returns a new list with the element added to it. If you really need something like an add method you need a mutable collection, e.g. http://www.scala-lang.org/api/current/scala/collection/mutable/MutableList.html which has a += method.

In Ruby, a block is basically a chunk of code that can be passed to and executed by any method. Blocks are always used with methods, which usually feed data to them (as arguments).

Blocks are widely used in Ruby gems (including Rails) and in well-written Ruby code. They are not objects, hence cannot be assigned to variables.

Basic Syntax

A block is a piece of code enclosed by { } or do..end. By convention, the curly brace syntax should be used for single-line blocks and the do..end syntax should be used for multi-line blocks.

{ # This is a single line block }

do
  # This is a multi-line block
end 

Any method can receive a block as an implicit argument. A block is executed by the yield statement within a method. The basic syntax is:

def meditate
  print "Today we will practice zazen"
  yield # This indicates the method is expecting a block
end 

# We are passing a block as an argument to the meditate method
meditate { print " for 40 minutes." }

Output:
Today we will practice zazen for 40 minutes.

When the yield statement is reached, the meditate method yields control to the block, the code within the block is executed and control is returned to the method, which resumes execution immediately following the yield statement.

When a method contains a yield statement, it is expecting to receive a block at calling time. If a block is not provided, an exception will be thrown once the yield statement is reached. We can make the block optional and avoid an exception from being raised:

def meditate
  puts "Today we will practice zazen."
  yield if block_given? 
end meditate

Output:
Today we will practice zazen. 

It is not possible to pass multiple blocks to a method. Each method can receive only one block.

In Azure Devops browser(pipeline yaml editor),

Ctrl + K + C Comment Block

Ctrl + K + U Uncomment Block

There also a 'Toggle Block Comment' option but this did not work for me.

There are other 'wierd' ways too: right click to see 'Command Palette' or F1

Then choose a cursor option.

Now it is just a matter of #

just get into the zabbix.conf.php

   >$sudo vim /etc/zabbix/web/zabbix.conf.php
   >$ZBX_SERVER      = '**your zabbix ip address or DNS name**';
   >$ZBX_SERVER_PORT = '10051';
   >$ZBX_SERVER_NAME = '**your zabbix hostname**';

just change the ip address you can resolve the error

Zabbix server is not running: the information displayed may not be current

After that restart the zabbix server

 >$sudo service zabbix-server restart

To verify go to Dashboard Administration -> queue there you see data

i resolved my error like this works fine for me.

There is part of the spec that sure sounds like this... right in the "flex layout algorithm" and "main sizing" sections:

Otherwise, starting from the first uncollected item, collect consecutive items one by one until the first time that the next collected item would not fit into the flex container’s inner main size, or until a forced break is encountered. If the very first uncollected item wouldn’t fit, collect just it into the line. A break is forced wherever the CSS2.1 page-break-before/page-break-after [CSS21] or the CSS3 break-before/break-after [CSS3-BREAK] properties specify a fragmentation break.

From http://www.w3.org/TR/css-flexbox-1/#main-sizing

It sure sounds like (aside from the fact that page-breaks ought to be for printing), when laying out a potentially multi-line flex layout (which I take from another portion of the spec is one without flex-wrap: nowrap) a page-break-after: always or break-after: always should cause a break, or wrap to the next line.

.flex-container {
  display: flex;
  flex-flow: row wrap;
}

.child {
  flex-grow: 1;
}

.child.break-here {
  page-break-after: always;
  break-after: always;
}

However, I have tried this and it hasn't been implemented that way in...

• Safari (up to 7)
• Chrome (up to 43 dev)
• Opera (up to 28 dev & 12.16)
• IE (up to 11)

It does work the way it sounds (to me, at least) like in:

• Firefox (28+)

Sample at http://codepen.io/morewry/pen/JoVmVj.

I didn't find any other requests in the bug tracker, so I reported it at https://code.google.com/p/chromium/issues/detail?id=473481.

But the topic took to the mailing list and, regardless of how it sounds, that's not what apparently they meant to imply, except I guess for pagination. So there's no way to wrap before or after a particular box in flex layout without nesting successive flex layouts inside flex children or fiddling with specific widths (e.g. flex-basis: 100%).

This is deeply annoying, of course, since working with the Firefox implementation confirms my suspicion that the functionality is incredibly useful. Aside from the improved vertical alignment, the lack obviates a good deal of the utility of flex layout in numerous scenarios. Having to add additional wrapping tags with nested flex layouts to control the point at which a row wraps increases the complexity of both the HTML and CSS and, sadly, frequently renders order useless. Similarly, forcing the width of an item to 100% reduces the "responsive" potential of the flex layout or requires a lot of highly specific queries or count selectors (e.g. the techniques that may accomplish the general result you need that are mentioned in the other answers).

At least floats had clear. Something may get added at some point or another for this, one hopes.

From within your TableViewController.m :

self.navigationController.navigationBar.topItem.title = @"Blah blah Some Amazing title";

Use jQuery's IsNumeric method.

http://api.jquery.com/jQuery.isNumeric/

if ($.isNumeric(id)) {
   //it's numeric
}

CORRECTION: that would not ensure an integer. This would:

if ( (id+"").match(/^\d+$/) ) {
   //it's all digits
}

That, of course, doesn't use jQuery, but I assume jQuery isn't actually mandatory as long as the solution works

Thx Burhan Khalid, I overlooked your "You need to be root" quote, but found the way when you are not the root here.

At point 7 you need to use:

sudo env ORACLE_HOME=$ORACLE_HOME python setup.py install 

Or

You should convert first DataSource in BindingSource, look example

BindingSource bs = (BindingSource)dgrid.DataSource; // Se convierte el DataSource 
DataTable tCxC = (DataTable) bs.DataSource;

With the data of tCxC you can do anything.

The question is already answered, but you can resolve it like this:

File dependency.js

const doSomething = (x) => x
export default doSomething;

File myModule.js

import doSomething from "./dependency";

export default (x) => doSomething(x * 2);

File myModule.spec.js

jest.mock('../dependency');
import doSomething from "../dependency";
import myModule from "../myModule";

describe('myModule', () => {
  it('calls the dependency with double the input', () => {
    doSomething.mockImplementation((x) => x * 10)

    myModule(2);

    expect(doSomething).toHaveBeenCalledWith(4);
    console.log(myModule(2)) // 40
  });
});

sys.argv[0] is not the first argument but the filename of the python program you are currently executing. I think you want sys.argv[1]

Use the following code:

<g transform="scale(0.1)">
...
</g>

I had the same error, but in my case apparently it was a synchronization issue, at the moment of render the components html.

I followed some of the solutions proposed on this page but any of them worked for me, at least not completely.

What did actually solve my error was to write the below code snippet inside the father html tag of the elements .

I was binding to the variable.

Code:

    *ngIf="variable-name"

The error was caused, apparently by the project trying to render the page, apparently at the moment of evaluating the variable, the project just could no find its value. With the above code snippet you make sure that before rendering the page you ask if the variable has being initialized.

This is my component.ts code:

import { Component, OnInit } from '@angular/core';
import { InvitationService } from 'src/app/service/invitation.service';
import { BusinessService } from 'src/app/service/business.service';
import { Invitation } from 'src/app/_models/invitation';
import { forEach } from '@angular/router/src/utils/collection';

@Component({
  selector: 'app-invitation-details',
  templateUrl: './invitation-details.component.html',
  styleUrls: ['./invitation-details.component.scss']
})
export class InvitationDetailsComponent implements OnInit {
  invitationsList: any;
  currentInvitation: any;
  business: any;
  invitationId: number;
  invitation: Invitation;

  constructor(private InvitationService: InvitationService, private BusinessService: 
BusinessService) { 
this.invitationId = 1; //prueba temporal con invitacion 1
this.getInvitations();
this.getInvitationById(this.invitationId);
  }

   ngOnInit() {

  }

  getInvitations() {
    this.InvitationService.getAllInvitation().subscribe(result => {
      this.invitationsList = result;
      console.log(result);
    }, error => {
      console.log(JSON.stringify(error));
    });
  }

  getInvitationById(invitationId:number){
    this.InvitationService.getInvitationById(invitationId).subscribe(result => {
      this.currentInvitation = result;
      console.log(result);
      //this.business=this.currentInvitation['business'];
       //console.log(this.currentInvitation['business']); 
     }, error => {
     console.log(JSON.stringify(error));
    });
  }
      ...

Here is my html markup:

<div class="container-fluid mt--7">
  <div class="row">
    <div class="container col-xl-10 col-lg-8">
      <div class="card card-stats ">
        <div class="card-body container-fluid form-check-inline" 
         *ngIf="currentInvitation">
          <div class="col-4">
             ...

I hope this can be helpful.

I would just go with

<tr @(if (count++ % 2 == 0){<text>class="alt-row"</text>})>

Or even better

<tr class="alt-row@(count++ % 2)">

this will give you lines like

<tr class="alt-row0">
<tr class="alt-row1">
<tr class="alt-row0">
<tr class="alt-row1">

If you happen to stumble on this topic in these days of modern browsers you can use pseudo-class :after to do practicaly anything with the background.

.container:after{
    content:"";
    position:absolute;
    right:20px;
    background:url(http://lorempixel.com/400/200) no-repeat right bottom;
}

this css will put background to bottom right corner of ".container" element with 20px space on the right side.

See this fiddle for example http://jsfiddle.net/h6K9z/226/

You can convert a string to a DATE using the TO_DATE function, then reformat the date as another string using TO_CHAR, i.e.:

SELECT TO_CHAR(
         TO_DATE('15/August/2009,4:30 PM'
                ,'DD/Month/YYYY,HH:MI AM')
       ,'DD-MM-YYYY')
FROM DUAL;

15-08-2009

For example, if your table name is MYTABLE and the varchar2 column is MYDATESTRING:

SELECT TO_CHAR(
         TO_DATE(MYDATESTRING
                ,'DD/Month/YYYY,HH:MI AM')
       ,'DD-MM-YYYY')
FROM MYTABLE;

You can use the standard isspace() function in ctype.h to achieve this. Simply compare the beginning and end characters of your character array until both ends no longer have spaces.

"spaces" include:

' ' (0x20) space (SPC)

'\t' (0x09) horizontal tab (TAB)

'\n' (0x0a) newline (LF)

'\v' (0x0b) vertical tab (VT)

'\f' (0x0c) feed (FF)

'\r' (0x0d) carriage return (CR)

although there is no function which will do all of the work for you, you will have to roll your own solution to compare each side of the given character array repeatedly until no spaces remain.

Edit:

Since you have access to C++, Boost has a trim implementation waiting for you to make your life a lot easier.

Google Drive folders can be embedded and displayed in list and grid views:

List view

<iframe src="https://drive.google.com/embeddedfolderview?id=FOLDER-ID#list" style="width:100%; height:600px; border:0;"></iframe>

Grid view

<iframe src="https://drive.google.com/embeddedfolderview?id=FOLDER-ID#grid" style="width:100%; height:600px; border:0;"></iframe>

Q: What is a folder ID (FOLDER-ID) and how can I get it?

A: Go to Google Drive >> open the folder >> look at its URL in the address bar of your browser. For example:

Folder URL: https://drive.google.com/drive/folders/0B1iqp0kGPjWsNDg5NWFlZjEtN2IwZC00NmZiLWE3MjktYTE2ZjZjNTZiMDY2

Folder ID:
0B1iqp0kGPjWsNDg5NWFlZjEtN2IwZC00NmZiLWE3MjktYTE2ZjZjNTZiMDY2

Caveat with folders requiring permission

This technique works best for folders with public access. Folders that are shared only with certain Google accounts will cause trouble when you embed them this way. At the time of this edit, a message "You need permission" appears, with some buttons to help you "Request access" or "Switch accounts" (or possibly sign-in to a Google account). The Javascript in these buttons doesn't work properly inside an IFRAME in Chrome.

As some people already said that it is not possible to prevent people to download your pictures, a trick could be something like this:

$(document).ready(function()
{
    $('img').bind('contextmenu', function(e){
        return false;
    }); 
});

This trick prevents from the right click on all img. Obviously people can open the source code and download the images using links in your source code.

My problem was took IBOutlet but didn't connect with interface builder and using in swift file.

Most likely you don't want to deactivate this Header completely, but use SAMEORIGIN. If you are using the Java Configs (Spring Boot) and would like to allow the X-Frame-Options: SAMEORIGIN, then you would need to use the following.

For older Spring Security versions:

http
   .headers()
       .addHeaderWriter(new XFrameOptionsHeaderWriter(XFrameOptionsHeaderWriter.XFrameOptionsMode.SAMEORIGIN))

For newer versions like Spring Security 4.0.2:

http
   .headers()
      .frameOptions()
         .sameOrigin();

Check on yourCheckBox.Value ?

You can stop a query which is being processed by this

Find the Id of the query process by => show processlist;

Then => kill id;

However, it is too slow on running

Yes, I've had the same problem. Some of the file downloads are extremely slow (or at least they have been in the last couple of days). If you want to download everything there's not a lot you can do about that.

The result is that nothing in folder build-tools, and I want is aapt and apkbuilder, since I want to build apk from command line without ant.

Did you let it run to completion?

One thing you can do is filter the packages that are being downloaded using the -t switch.

For example:

tools/android update sdk --no-ui -t platform-tool

When I tried this the other day I got version 18.0.0 of the build tools installed. For some reason the latest version 18.0.1 is not included by this filter and the only way to get it was to install everything with the --all switch.

Something I noticed was that I had "other_database" and "Other_Database" in my databases. That caused this problem as I actually had same reference in other database which caused this mysterious error!

From this forum:

parseInt() returns primitive integer type (int), whereby valueOf returns java.lang.Integer, which is the object representative of the integer. There are circumstances where you might want an Integer object, instead of primitive type.

Of course, another obvious difference is that intValue is an instance method whereby parseInt is a static method.

The new Aggregation Framework in MongoDB 2.2+ provides an alternative to Map/Reduce. The $unwind operator can be used to separate your shapes array into a stream of documents that can be matched:

db.test.aggregate(
  // Start with a $match pipeline which can take advantage of an index and limit documents processed
  { $match : {
     "shapes.color": "red"
  }},
  { $unwind : "$shapes" },
  { $match : {
     "shapes.color": "red"
  }}
)

Results in:

{
    "result" : [
        {
            "_id" : ObjectId("504425059b7c9fa7ec92beec"),
            "shapes" : {
                "shape" : "circle",
                "color" : "red"
            }
        }
    ],
    "ok" : 1
}

In my case, I want the name of the renamed file to be unique, so I add a date-time stamp to the name. This way, the filename of the 'old' log is always unique:

if (File.Exists(clogfile))
{
    Int64 fileSizeInBytes = new FileInfo(clogfile).Length;
    if (fileSizeInBytes > 5000000)
    {
        string path = Path.GetFullPath(clogfile);
        string filename = Path.GetFileNameWithoutExtension(clogfile);
        System.IO.File.Move(clogfile, Path.Combine(path, string.Format("{0}{1}.log", filename, DateTime.Now.ToString("yyyyMMdd_HHmmss"))));
    }
}

This is due to using obsolete mysql-connection-java version, your MySQl is updated but not your MySQL jdbc Driver, you can update your connection jar from the official site Official MySQL Connector site. Good Luck.

I came up with a totally different solution. I needed to analyse video still frames to find the sharpest one in every (X) frames. This way, I would detect motion blur and/or out of focus images.

I ended up using Canny Edge detection and I got VERY VERY good results with almost every kind of video (with nikie's method, I had problems with digitalized VHS videos and heavy interlaced videos).

I optimized the performance by setting a region of interest (ROI) on the original image.

Using EmguCV :

//Convert image using Canny
using (Image<Gray, byte> imgCanny = imgOrig.Canny(225, 175))
{
    //Count the number of pixel representing an edge
    int nCountCanny = imgCanny.CountNonzero()[0];

    //Compute a sharpness grade:
    //< 1.5 = blurred, in movement
    //de 1.5 à 6 = acceptable
    //> 6 =stable, sharp
    double dSharpness = (nCountCanny * 1000.0 / (imgCanny.Cols * imgCanny.Rows));
}

If you have multiple textField that have various length checks on one page I've found an easy and short solution.

class MultipleTextField: UIViewController {

    let MAX_LENGTH_TEXTFIELD_A = 10
    let MAX_LENGTH_TEXTFIELD_B = 11

    lazy var textFieldA: UITextField = {
        let textField = UITextField()
        textField.tag = MAX_LENGTH_TEXTFIELD_A
        textField.delegate = self
        return textField
    }()
    lazy var textFieldB: UITextField = {
        let textField = UITextField()
        textField.tag = MAX_LENGTH_TEXTFIELD_B
        textField.delegate = self
        return textField
    }()
}

extension MultipleTextField: UITextFieldDelegate {
    func textField(_ textField: UITextField, shouldChangeCharactersIn range: NSRange, replacementString string: String) -> Bool {
        return (range.location < textField.tag) && (string.count < textField.tag)
    }
}

A transient variable is a variable that may not be serialized.

One example of when this might be useful that comes to mind is, variables that make only sense in the context of a specific object instance and which become invalid once you have serialized and deserialized the object. In that case it is useful to have those variables become null instead so that you can re-initialize them with useful data when needed.

You need to add the following lines in your catalina.sh file.

export CATALINA_OPTS="-Xms512M -Xmx1024M"

UPDATE : catalina.sh content clearly says -

Do not set the variables in this script. Instead put them into a script setenv.sh in CATALINA_BASE/bin to keep your customizations separate.

So you can add above in setenv.sh instead (create a file if it does not exist).

' Create The Object
Set FSO = CreateObject("Scripting.FileSystemObject")

' How To Write To A File
Set File = FSO.CreateTextFile("C:\foo\bar.txt",True)
File.Write "Example String"
File.Close

' How To Read From A File
Set File = FSO.OpenTextFile("C:\foo\bar.txt")
Do Until File.AtEndOfStream
    Line = File.ReadLine
    WScript.Echo(Line)
Loop
File.Close

' Another Method For Reading From A File
Set File = FSO.OpenTextFile("C:\foo\bar.txt")
Set Text = File.ReadAll
WScript.Echo(Text)
File.Close

OPTION 1: Add this line to ~/.zshrc:

export "PATH=$HOME/pear/bin:$PATH"

After that you need to run source ~/.zshrc in order your changes to take affect OR close this window and open a new one

OPTION 2: execute it inside the terminal console to add this path only to the current terminal window session. When you close the window/session, it will be lost.

If you don't want to use numpy, you could use the list of lists concept. To create any 2D array, just use the following syntax:

  mat = [[input() for i in range (col)] for j in range (row)]

and then enter the values you want.

The solution is:

 $('body').scroll(function(e){
    console.log(e);
});

After initializing your UI component and fill it with data. add those line to your on create method

Runnable runnable=new Runnable() {
        @Override
        public void run() {
            scrollView.fullScroll(ScrollView.FOCUS_DOWN);
        }
    };
    scrollView.post(runnable);

There is an alternative for creating an iframe whose contents are a string of HTML: the srcdoc attribute. This is not supported in older browsers (chief among them: Internet Explorer, and possibly Safari?), but there is a polyfill for this behavior, which you could put in conditional comments for IE, or use something like has.js to conditionally lazy load it.

You can use the Firefox add-on called SQLite Manager to view the database's structure clearly.

surely you can do this with worksheet formulas, avoiding VBA entirely:

so for this value in say, column AV S:1 P:0 K:1 Q:1

you put this formula in column BC:

=MID(AV:AV,FIND("S",AV:AV)+2,1)

then these formulas in columns BD, BE...

=MID(AV:AV,FIND("P",AV:AV)+2,1)
=MID(AV:AV,FIND("K",AV:AV)+2,1)
=MID(AV:AV,FIND("Q",AV:AV)+2,1)

so these formulas look for the values S:1, P:1 etc in column AV. If the FIND function returns an error, then 0 is returned by the formula, else 1 (like an IF, THEN, ELSE

Then you would just copy down the formulas for all the rows in column AV.

If you are using Netbeans using Maven to add library is easier. I have tried using above solutions but it didn't work.

<dependencies>
    <dependency>
      <groupId>org.xerial</groupId>
      <artifactId>sqlite-jdbc</artifactId>
      <version>3.7.2</version>
    </dependency>
</dependencies>

I have added Maven dependency and java.lang.ClassNotFoundException: org.sqlite.JDBC error gone.

This may help you find what you're looking for... Batch script loop

My answer is as follows:

@echo off
:start
set /a var+=1
if %var% EQU 100 goto end
:: Code you want to run goes here
goto start

:end
echo var has reached %var%.
pause
exit

The first set of commands under the start label loops until a variable, %var% reaches 100. Once this happens it will notify you and allow you to exit. This code can be adapted to your needs by changing the 100 to 17 and putting your code or using a call command followed by the batch file's path (Shift+Right Click on file and select "Copy as Path") where the comment is placed.

I've been coding for about 2 weeks and created a simple logic to validate an integer has been accepted.

    Console.WriteLine("How many numbers do you want to enter?"); // request a number
    string input = Console.ReadLine(); // set the input as a string variable
    int numberTotal; // declare an int variable

    if (!int.TryParse(input, out numberTotal)) // process if input was an invalid number
    {
        while (numberTotal  < 1) // numberTotal is set to 0 by default if no number is entered
        {
            Console.WriteLine(input + " is an invalid number."); // error message
            int.TryParse(Console.ReadLine(), out numberTotal); // allows the user to input another value
        }

    } // this loop will repeat until numberTotal has an int set to 1 or above

you could also use the above in a FOR loop if you prefer by not declaring an action as the third parameter of the loop, such as

    Console.WriteLine("How many numbers do you want to enter?");
    string input2 = Console.ReadLine();

    if (!int.TryParse(input2, out numberTotal2))
    {
        for (int numberTotal2 = 0; numberTotal2 < 1;)
        {
            Console.WriteLine(input2 + " is an invalid number.");
            int.TryParse(Console.ReadLine(), out numberTotal2);
        }

    }

if you don't want a loop, simply remove the entire loop brace

You can use MimeMappings class. I think this is the easiest way. I give import of MimeMappings too. because I felt lots of trouble to find import of those classes.

import org.springframework.boot.web.server.MimeMappings;    
MimeMappings mm=new MimeMappings();
String mimetype = mm.get(fileExtension);
System.out.println(mimetype);

You can specify the min and max attributes, which will allow input only within a specific range.

<!-- equivalent to maxlength=4 -->
<input type="number" min="-9999" max="9999">

This only works for the spinner control buttons, however. Although the user may be able to type a number greater than the allowed max, the form will not submit.

^{Screenshot taken from Chrome 15}

You can use the HTML5 oninput event in JavaScript to limit the number of characters:

myInput.oninput = function () {
    if (this.value.length > 4) {
        this.value = this.value.slice(0,4); 
    }
}

Unique pointers are guaranteed to destroy the object they manage when they go out of scope. http://en.cppreference.com/w/cpp/memory/unique_ptr

In this case:

unique_ptr<double> uptr2 (pd);

pd will be destroyed when uptr2 goes out of scope. This facilitates memory management by automatic deletion.

The case of unique_ptr<int> uptr (new int(3)); is not different, except that the raw pointer is not assigned to any variable here.

I'm a PHP developer and to be able to work on my development environment with a certificate, I was able to do the same by finding the real SSL HTTPS/HTTP Certificate and deleting it.

The steps are :

1. In the address bar, type "chrome://net-internals/#hsts".
2. Type the domain name in the text field below "Delete domain".
3. Click the "Delete" button.
4. Type the domain name in the text field below "Query domain".
5. Click the "Query" button.
6. Your response should be "Not found".

Although this solution is not the best, Chrome currently does not have any good solution for the moment. I have escalated this situation with their support team to help improve user experience.

Edit : you have to repeat the steps every time you will go on the production site.

Your problem is probably that a elements are display: inline by nature. You can't set the width and height of inline elements.

You would have to set display: block on the a, but that will bring other problems because the links start behaving like block elements. The most common cure to that is giving them float: left so they line up side by side anyway.

You could try:

agg <- aggregate(list(x$val1, x$val2, x$val3, x$val4), by = list(x$id1, x$id2), mean)

I've wrestled with this myself, trying to make it work from the server. Couldn't. Instead...

1. To clarify on @dnc253's answer, $window.open(URL) is a method for having an Angular application open a given URL in another window. (It's really just a testable angular proxy for the universal window.open().) This is a great solution, preserves your history, and gets the file downloaded and possibly renders it in that fresh browser window if that's supported. But it often runs into popup blockers, which is a huge problem for reliability. Users often simply don't understand what's going on with them. So, if you don't mind immediately downloading the file with the current window, you can simply use the equally effective universal javascript method: location.href = "uriString", which works like a charm for me. Angular doesn't even realize anything has happened. I call it in a promise handler for once my POST/PUT operation has completed. If need be, have the POST/PUT return the URL to call, if you can't already infer it. You'll get the same behavior for the user as if it had downloaded in response to the PUT/POST. For example:

   $http.post(url, payload).then(function(returnData){
       var uriString = parseReturn(returnData);
       location.href="uriString"
   })
   

2. You can, in fact, download something directly from an XHR request, but it requires full support for the HTML5 file API and is usually more trouble than it's worth unless you need to perform local transformations upon the file before you make it available to the user. (Sadly, I lack the time to provide details on that but there are other SO posts about using it.)

It can be done, I found it elsewhere on the web...this is no way my work ! :)

Just install dos2unix then to convert a file in place use

dos2unix <filename>

To output converted text to a different file use

dos2unix -n <input-file> <output-file>

You can install it on Ubuntu or Debian with

sudo apt install dos2unix

or on macOS using homebrew

brew install dos2unix

I was searching for this very same thing. I had read that this was available in Bootstrap 3.0, but I was having no luck in actually implementing it. This is what I came up with and it works great. Very simple jQuery and Javascript.

Here is the JSFiddle to play around with... http://jsfiddle.net/CriddleCraddle/Wj9dD/

The solution is very similar to other solutions on the web and StackOverflow. If you do not find this one useful, search for what you need. Goodluck!

Here is the HTML...

<div id="banner">
  <h2>put what you want here</h2>
  <p>just adjust javascript size to match this window</p>
</div>

  <nav id='nav_bar'>
    <ul class='nav_links'>
      <li><a href="url">Sign In</a></li>
      <li><a href="url">Blog</a></li>
      <li><a href="url">About</a></li>
    </ul>
  </nav>

<div id='body_div'>
  <p style='margin: 0; padding-top: 50px;'>and more stuff to continue scrolling here</p>
</div>

Here is the CSS...

html, body {
  height: 4000px;
}

.navbar-fixed {
  top: 0;
  z-index: 100;
  position: fixed;
  width: 100%;
}

#body_div {
  top: 0;
  position: relative;
  height: 200px;
  background-color: green;
}

#banner {
  width: 100%;
  height: 273px;
  background-color: gray;
  overflow: hidden;
}

#nav_bar {
  border: 0;
  background-color: #202020;
  border-radius: 0px;
  margin-bottom: 0;
  height: 30px;
}

//the below css are for the links, not needed for sticky nav
.nav_links {
  margin: 0;
}

.nav_links li {
  display: inline-block;
  margin-top: 4px;
}

.nav_links li a {
  padding: 0 15.5px;
  color: #3498db;
  text-decoration: none;
}

Now, just add the javacript to add and remove the fix class based on the scroll position.

$(document).ready(function() {
  //change the integers below to match the height of your upper div, which I called
  //banner.  Just add a 1 to the last number.  console.log($(window).scrollTop())
  //to figure out what the scroll position is when exactly you want to fix the nav
  //bar or div or whatever.  I stuck in the console.log for you.  Just remove when
  //you know the position.
  $(window).scroll(function () { 

    console.log($(window).scrollTop());

    if ($(window).scrollTop() > 550) {
      $('#nav_bar').addClass('navbar-fixed-top');
    }

    if ($(window).scrollTop() < 551) {
      $('#nav_bar').removeClass('navbar-fixed-top');
    }
  });
});

Use this method

public static void setColumnWidths(JTable table, int... widths) {
    TableColumnModel columnModel = table.getColumnModel();
    for (int i = 0; i < widths.length; i++) {
        if (i < columnModel.getColumnCount()) {
            columnModel.getColumn(i).setMaxWidth(widths[i]);
        }
        else break;
    }
}

Or extend the JTable class:

public class Table extends JTable {
    public void setColumnWidths(int... widths) {
        for (int i = 0; i < widths.length; i++) {
            if (i < columnModel.getColumnCount()) {
                columnModel.getColumn(i).setMaxWidth(widths[i]);
            }
            else break;
        }
    }
}

And then

table.setColumnWidths(30, 150, 100, 100);

For an easy and appropriate way of doing this, first download a prepackaged release of freeglut from here. Then read its Readme.txt.

I copied some important parts of that package here:

... Create a folder on your PC which is readable by all users, for example “C:\Program Files\Common Files\MSVC\freeglut\” on a typical Windows system. Copy the “lib\” and “include\” folders from this zip archive to that location ... freeglut DLL can be placed in the same folder as your application...

... Open up the project properties, and select “All Configurations” (this is necessary to ensure our changes are applied for both debug and release builds). Open up the “general” section under “C/C++”, and configure the “include\” folder you created above as an “Additional Include Directory”. If you have more than one GLUT package which contains a “glut.h” file, it’s important to ensure that the freeglut include folder appears above all other GLUT include folders ... Open up the “general” section under “Linker”, and configure the “lib\” folder you created above as an “Additional Library Directory”...

Recommendations for how to catch which part of your CSS is causing the issue:

1) set style="height:auto;" on all the <div> elements and retry again.

2) Set style="border: 3px solid red;" on all the <div> elements to see how wide of an area your <div>'s box is taking up.

3) Take away all the css height:#px; properties from your CSS and start over.

So for example:

<div id="I" style="height:auto;border: 3px solid red;">I
    <div id="A" style="height:auto;border: 3px solid purple;">A
        <div id="1A" style="height:auto;border: 3px solid green;">1A
        </div>
        <div id="2A" style="height:auto;border: 3px solid green;">2A
        </div>
    </div>
    <div id="B" style="height:auto;border: 3px solid purple;">B
        <div id="1B" style="height:auto;border: 3px solid green;">1B
        </div>
        <div id="2B" style="height:auto;border: 3px solid green;">2B
        </div>
    </div>
</div>

Or with Prototype:

Event.observe(this, 'load', function() { new Ajax.Request(... ) );

Or better, define the function elsewhere rather than inline, then:

Event.observe(this, 'load', functionName );

You don't have to use jQuery or Prototype specifically, but I hope you're using some kind of library. Either library is going to handle the event handling in a more consistent manner than onload, and of course is going to make it much easier to process the Ajax call. If you must use the body onload attribute, then you should just be able to call the same function as referenced in these examples (onload="javascript:functionName();").

However, if your database update doesn't depend on the rendering on the page, why wait until it's fully loaded? You could just include a call to the Ajax-calling function at the end of the JavaScript on the page, which should give nearly the same effect.

window load will wait for all resources to be loaded.

document ready waits for the document to be initialized.

unload well, waits till the document is being unloaded.

the order is: document ready, window load, ... ... ... ... window unload.

always use document ready unless you need to wait for your images to load.

shorthand for document ready:

$(function(){
    // yay!
});

Use the command svn status on your working copy to show the status of files, files that are not yet under version control (and not ignored) will have a question mark next to them.

As for ignoring files you need to edit the svn:ignore property, read the chapter Ignoring Unversioned Items in the svnbook at http://svnbook.red-bean.com/en/1.5/svn.advanced.props.special.ignore.html. The book also describes more about using svn status.

console.log does not produce any message box. I don't think it is available in any version of IE (nor Firefox) without the addition of firebug or some equivalent.

It is however available in Safari and Chrome. Since you mention Chrome I'll use that for my example.

You'll need to open your window and its developer window counterpart. you can do this by right clicking any element on the page and selecting "Inspect element". your window will be divided in two parts, the developer part being the bottom. in the division between the two parts is a bar with buttons and the rightmost button there is labeled "console". You'll need to click that to switch to the console tab. Press F12 for developer tools in most browsers on Windows, command + shift + I on macOS.

Once there, you will be able to interact with whatever page is loaded on top through javascript from that console, and any messages you console.log will be displayed there.

It seems everybody is throwing their own version of the unique filter into the ring, so I'll do the same. Critique is very welcome.

angular.module('myFilters', [])
  .filter('unique', function () {
    return function (items, attr) {
      var seen = {};
      return items.filter(function (item) {
        return (angular.isUndefined(attr) || !item.hasOwnProperty(attr))
          ? true
          : seen[item[attr]] = !seen[item[attr]];
      });
    };
  });

IDLE TO VISUAL STUDIO USERS: I ran into this problem as well when moving code directly from IDLE to Visual Studio. When you press tab IDLE adds 4 spaces instead of a tab. In IDLE, hit Ctl+A to select all of the code and go to Format>Tabify Region. Now move the code to visual studio and most errors should be fixed. Every so often there will be code that is off-tab, just fix it manually.

it simple, select columns want to insert primary key and click on Key icon on header and save table

happy coding..,

C# equivalent of your code is

  class Imagedata : PDFStreamEngine
  {
     // C# uses "base" keyword whenever Java uses "super" 
     // so instead of super(...) in Java we should call its C# equivalent (base):
     public Imagedata()
       : base(ResourceLoader.loadProperties("org/apache/pdfbox/resources/PDFTextStripper.properties", true)) 
     { }

     // Java methods are virtual by default, when C# methods aren't.
     // So we should be sure that processOperator method in base class 
     // (that is PDFStreamEngine)
     // declared as "virtual"
     protected override void processOperator(PDFOperator operations, List arguments)
     {
        base.processOperator(operations, arguments);
     }
  }

Thanks Guy.

With a slight variation I used it to find all the primary keys for all the tables.

SELECT A.Name,Col.Column_Name from 
    INFORMATION_SCHEMA.TABLE_CONSTRAINTS Tab, 
    INFORMATION_SCHEMA.CONSTRAINT_COLUMN_USAGE Col ,
    (select NAME from dbo.sysobjects where xtype='u') AS A
WHERE 
    Col.Constraint_Name = Tab.Constraint_Name
    AND Col.Table_Name = Tab.Table_Name
    AND Constraint_Type = 'PRIMARY KEY '
    AND Col.Table_Name = A.Name

ModelSim-Altera error

Here's an example that shows how table(.) (or, more closely matching your desired output, data.frame(table(.)) does what it sounds like you are asking for.

Note also how to share reproducible sample data in a way that others can copy and paste into their session.

Here's the (reproducible) sample data:

mydf <- structure(list(ID = c(110L, 111L, 121L, 131L, 141L), 
                       MONTH.YEAR = c("JAN. 2012", "JAN. 2012", 
                                      "FEB. 2012", "FEB. 2012", 
                                      "MAR. 2012"), 
                       VALUE = c(1000L, 2000L, 3000L, 4000L, 5000L)), 
                  .Names = c("ID", "MONTH.YEAR", "VALUE"), 
                  class = "data.frame", row.names = c(NA, -5L))

mydf
#    ID MONTH.YEAR VALUE
# 1 110  JAN. 2012  1000
# 2 111  JAN. 2012  2000
# 3 121  FEB. 2012  3000
# 4 131  FEB. 2012  4000
# 5 141  MAR. 2012  5000

Here's the calculation of the number of rows per group, in two output display formats:

table(mydf$MONTH.YEAR)
# 
# FEB. 2012 JAN. 2012 MAR. 2012 
#         2         2         1

data.frame(table(mydf$MONTH.YEAR))
#        Var1 Freq
# 1 FEB. 2012    2
# 2 JAN. 2012    2
# 3 MAR. 2012    1

Here's another one:

=indirect("A"&max(arrayformula(if(A:A<>"",row(A:A),""))))

With the final equation being this:

=DAYS360(A2,indirect("A"&max(arrayformula(if(A:A<>"",row(A:A),"")))))

The other equations on here work, but I like this one because it makes getting the row number easy, which I find I need to do more often. Just the row number would be like this:

=max(arrayformula(if(A:A<>"",row(A:A),"")))

I originally tried to find just this to solve a spreadsheet issue, but couldn't find anything useful that just gave the row number of the last entry, so hopefully this is helpful for someone.

Also, this has the added advantage that it works for any type of data in any order, and you can have blank rows in between rows with content, and it doesn't count cells with formulas that evaluate to "". It can also handle repeated values. All in all it's very similar to the equation that uses max((G:G<>"")*row(G:G)) on here, but makes pulling out the row number a little easier if that's what you're after.

Alternatively, if you want to put a script on your sheet you can make it easy on yourself if you plan on doing this a lot. Here's that scirpt:

function lastRow(sheet,column) {
  var ss = SpreadsheetApp.getActiveSpreadsheet();
  if (column == null) {
    if (sheet != null) {
       var sheet = ss.getSheetByName(sheet);
    } else {
      var sheet = ss.getActiveSheet();
    }
    return sheet.getLastRow();
  } else {
    var sheet = ss.getSheetByName(sheet);
    var lastRow = sheet.getLastRow();
    var array = sheet.getRange(column + 1 + ':' + column + lastRow).getValues();
    for (i=0;i<array.length;i++) {
      if (array[i] != '') {       
        var final = i + 1;
      }
    }
    if (final != null) {
      return final;
    } else {
      return 0;
    }
  }
}

Here you can just type in the following if you want the last row on the same of the sheet that you're currently editing:

=LASTROW()

or if you want the last row of a particular column from that sheet, or of a particular column from another sheet you can do the following:

=LASTROW("Sheet1","A")

And for the last row of a particular sheet in general:

=LASTROW("Sheet1")

Then to get the actual data you can either use indirect:

=INDIRECT("A"&LASTROW())

or you can modify the above script at the last two return lines (the last two since you would have to put both the sheet and the column to get the actual value from an actual column), and replace the variable with the following:

return sheet.getRange(column + final).getValue();

and

return sheet.getRange(column + lastRow).getValue();

One benefit of this script is that you can choose if you want to include equations that evaluate to "". If no arguments are added equations evaluating to "" will be counted, but if you specify a sheet and column they will now be counted. Also, there's a lot of flexibility if you're willing to use variations of the script.

Probably overkill, but all possible.

In the manifest:

<activity  android:name=".YourActivity"
android:screenOrientation="portrait"
android:configChanges="orientation|screenSize">

In your activity:

setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_LANDSCAPE);
setContentView(R.layout.your_activity_layout);

It lets you handle Many to Many relationship. Example:

Table 1: post

post has following columns
____________________
|  ID     |  DATE   |
|_________|_________|
|         |         |
|_________|_________|

Table 2: user

user has the following columns:

____________________
|     ID  |NAME     |
|_________|_________|
|         |         |
|_________|_________|

Join Table lets you create a mapping using:

@JoinTable(
  name="USER_POST",
  joinColumns=@JoinColumn(name="USER_ID", referencedColumnName="ID"),
  inverseJoinColumns=@JoinColumn(name="POST_ID", referencedColumnName="ID"))

will create a table:

____________________
|  USER_ID| POST_ID |
|_________|_________|
|         |         |
|_________|_________|

To answer your question, you can explore the contents of the model's output by saving the model as a variable and clicking on it in the environment window. You can then click around to see what it contains and what is stored where.

Another way is to type yourmodelname$ and select the components of the model one by one to see what each contains. When you get to yourmodelname$coefficients, you will see all of beta-, p, and t- values you desire.

If you really want Jackson to return a date with another time zone than UTC (and I myself have several good arguments for that, especially when some clients just don't get the timezone part) then I usually do:

ObjectMapper mapper = new ObjectMapper();
DateFormat dateFormat = new SimpleDateFormat("yyyy-MM-dd'T'HH:mm:ss.SSSZ");
dateFormat.setTimeZone(TimeZone.getTimeZone("CET"));
mapper.getSerializationConfig().setDateFormat(dateFormat);
// ... etc

It has no adverse effects on those that understand the timezone-p

When you get this error some annotation is missing. I was missing @service annotation on service. When I added that annotation it worked fine for me.

use grep -n -i null myfile.txt to output the line number in front of each match.

I dont think grep has a switch to print the count of total lines matched, but you can just pipe grep's output into wc to accomplish that:

grep -n -i null myfile.txt | wc -l

If you just want to insert a value at a certain position in a string, you can use the String.Insert method:

public string Insert(int startIndex, string value)

Example:

"abc".Insert(2, "XYZ") == "abXYZc"

list.append returns None, since it is an in-place operation and you are assigning it back to dates_dict[key]. So, the next time when you do dates_dict.get(key, []).append you are actually doing None.append. That is why it is failing. Instead, you can simply do

dates_dict.setdefault(key, []).append(date)

But, we have collections.defaultdict for this purpose only. You can do something like this

from collections import defaultdict
dates_dict = defaultdict(list)
for key, date in cur:
    dates_dict[key].append(date)

This will create a new list object, if the key is not found in the dictionary.

Note: Since the defaultdict will create a new list if the key is not found in the dictionary, this will have unintented side-effects. For example, if you simply want to retrieve a value for the key, which is not there, it will create a new list and return it.

You want to iterate through the list, sum all the numbers, and then divide the sum by the number of elements in the list. You can use a for loop to accomplish this.

average = 0
sum = 0    
for n in numbers:
    sum = sum + n
average = sum / len(numbers)

The for loop looks at each element in the list, and then adds it to the current sum. You then divide by the length of the list (or the number of elements in the list) to find the average.

I would recommend googling a python reference to find out how to use common programming concepts like loops and conditionals so that you feel comfortable when starting out. There are lots of great resources online that you could look up.

Good luck!

Yeah, you can call other method before of the call base or this!

public class MyException : Exception
{
    public MyException(int number) : base(ConvertToString(number)) 
    {
    }

    private static string ConvertToString(int number) 
    { 
      return number.toString()
    }

}

From ISO 8601 String to Java Date Object

SimpleDateFormat sdf = new SimpleDateFormat("yyyy-MM-dd'T'HH:mm:ss'Z'");
sdf.setTimeZone(TimeZone.getTimeZone("GMT"));
sdf.parse("2013-09-29T18:46:19Z"); //prints-> Mon Sep 30 02:46:19 CST 2013

if you don't set TimeZone.getTimeZone("GMT") then it will output Sun Sep 29 18:46:19 CST 2013

From Java Date Object to ISO 8601 String

And to convert Dateobject to ISO 8601 Standard (yyyy-MM-dd'T'HH:mm:ss'Z') use following code

SimpleDateFormat sdf = new SimpleDateFormat("yyyy-MM-dd'T'HH:mm:ss'Z'", Locale.US);
sdf.setTimeZone(TimeZone.getTimeZone("GMT"));           
System.out.println(sdf.format(new Date())); //-prints-> 2015-01-22T03:23:26Z

Also note that without ' ' at Z yyyy-MM-dd'T'HH:mm:ssZ prints 2015-01-22T03:41:02+0000

I guess your code relates to Windows Forms.
You call BeginInvoke if you need something to be executed asynchronously in the UI thread: change control's properties in most of the cases.
Roughly speaking this is accomplished be passing the delegate to some procedure which is being periodically executed. (message loop processing and the stuff like that)

If BeginInvoke is called for Delegate type the delegate is just invoked asynchronously.
(Invoke for the sync version.)

If you want more universal code which works perfectly for WPF and WinForms you can consider Task Parallel Library and running the Task with the according context. (TaskScheduler.FromCurrentSynchronizationContext())

And to add a little to already said by others: Lambdas can be treated either as anonymous methods or expressions.
And that is why you cannot just use var with lambdas: compiler needs a hint.

UPDATE:

this requires .Net v4.0 and higher

// This line must be called in UI thread to get correct scheduler
var scheduler = System.Threading.Tasks.TaskScheduler.FromCurrentSynchronizationContext();

// this can be called anywhere
var task = new System.Threading.Tasks.Task( () => someformobj.listBox1.SelectedIndex = 0);

// also can be called anywhere. Task  will be scheduled for execution.
// And *IF I'm not mistaken* can be (or even will be executed synchronously)
// if this call is made from GUI thread. (to be checked) 
task.Start(scheduler);

If you started the task from other thread and need to wait for its completition task.Wait() will block calling thread till the end of the task.

I am going out on a limb here to say that, don't get caught up in too many podcasts or blogs, but rather dive into technology/code and good tech books.

although +1 to;

• Thoughtworks - IT matters
• Software Engineering Radio
• Pragmatic podcasts
• Alt.Net podcasts
• Hanselminutes

and while not strictly technology

• Enterprise Thought Leaders from Stanford University, which often has speakers from fortune 500 and tech startups on how they made it.

When you run this command,

svn propedit svn:log --revprop -r NNN 

and just in case you see this message:

DAV request failed; it's possible that the repository's pre-revprop-change hook either failed or is non-existent

Its because Subversion doesn’t allow you to modify log messages because they are unversioned and will be lost permanently.

Unix-hosted SVN

Go to the hooks directory on your Subversion server (replace ~/svn/reponame with the directory of your repository)

cd ~/svn/reponame/hooks

Remove the extension

mv pre-revprop-change.tmpl pre-revprop-change

Make it executable (cannot do chmod +x!)

chmod 755 pre-revprop-change

Source

Windows-hosted SVN

The template files in the hooks directory cannot be used as they are Unix-specific. You need to copy a Windows batch file pre-revprop-change.bat to the hooks directory, e.g. the one provided here.

The suggestions marked as best are all true if your script consists of only one file.

If you want to find out the name of the executable (i.e. the root file passed to the python interpreter for the current program) from a file that may be imported as a module, you need to do this (let's assume this is in a file named foo.py):

import inspect

print inspect.stack()[-1][1]

Because the last thing ([-1]) on the stack is the first thing that went into it (stacks are LIFO/FILO data structures).

Then in file bar.py if you import foo it'll print bar.py, rather than foo.py, which would be the value of all of these:

• __file__
• inspect.getfile(inspect.currentframe())
• inspect.stack()[0][1]

>>> import math
>>> import numpy as np
>>> import scipy
>>> math.pi == np.pi == scipy.pi
True

So it doesn't matter, they are all the same value.

The only reason all three modules provide a pi value is so if you are using just one of the three modules, you can conveniently have access to pi without having to import another module. They're not providing different values for pi.

Taking the top answer, as well as the suggestions from its comments, and modifying it to use SecureString instead of String, test for all control keys, and not error or write an extra "*" to the screen when the password length is 0, my solution is:

public static SecureString getPasswordFromConsole(String displayMessage) {
    SecureString pass = new SecureString();
    Console.Write(displayMessage);
    ConsoleKeyInfo key;

    do {
        key = Console.ReadKey(true);

        // Backspace Should Not Work
        if (!char.IsControl(key.KeyChar)) {
            pass.AppendChar(key.KeyChar);
            Console.Write("*");
        } else {
            if (key.Key == ConsoleKey.Backspace && pass.Length > 0) {
                pass.RemoveAt(pass.Length - 1);
                Console.Write("\b \b");
            }
        }
    }
    // Stops Receving Keys Once Enter is Pressed
    while (key.Key != ConsoleKey.Enter);
    return pass;
}

Even adding responseType, I dealt with it for days with no success. Finally I got it. Make sure that in your backend script you don't define header as -("Content-Type: application/json);

Becuase if you turn it to text but backend asks for json, it will return an error...

For swift 4.0.

In your AppDelegate.swift file in didfinishedlaunchingWithOptions method, put the following code.

var window: UIWindow?


func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplicationLaunchOptionsKey: Any]?) -> Bool {
    window = UIWindow(frame: UIScreen.main.bounds)
    window?.makeKeyAndVisible()

    let rootVC = MainViewController() // your custom viewController. You can instantiate using nib too. UIViewController(nib name, bundle)
    //let rootVC = UIViewController(nibName: "MainViewController", bundle: nil) //or MainViewController()
    let navController = UINavigationController(rootViewController: rootVC) // Integrate navigation controller programmatically if you want

    window?.rootViewController = navController

    return true
}

Hope it will work just fine.

The switch method (as mentioned by Guffa) works very nicely indeed. However, the default warning settings in most linters will alert you about the use of fall-through. It's one of the main reasons I use switches at all, so I pretty much ignore this warning, but you should be aware that the using the fall-through feature of the switch statement can be tricky. In cases like this, though - I'd go for it.

Simple filter something like this (use numeric class on input end filter charchter in []):

<script type="text/javascript">
// Only allow number input
$('.numeric').keyup(function () {
    this.value = this.value.replace(/[^0-9+-\.\,\;\:\s()]/g, ''); // this is filter for telefon number !!!
});

How about checking with python code:

from tensorflow.python.platform import build_info as tf_build_info

print(tf_build_info.cudnn_version_number)
# 7 in v1.10.0

Try using

img.style.webkitTransform = "rotate(60deg)"

I had similar problems. I was also confused by some solutions leaving me with different versions displaying for different users. If you have any problems at all, I would first check every account your using any implementation of node

Finally, this solution appears to solve this issue 100%, giving me the confidence that my versions were universal no matter what user privileges I wanted to use:

    sudo yum update

    sudo yum install build-essential checkinstall libssl-dev

    curl -o- https://raw.githubusercontent.com/creationix/nvm/v0.35.1/install.sh | bash

    (sudo) nvm --version

    (sudo) nvm ls-remote

    (sudo) nvm install [version.number] 

1

If you're still having a problem, next try looking inside your /usr/local/bin directory. If you find either a large binary document named node or a folder named npm, delete them.

    rm /usr/local/bin/node

    rm -r /usr/local/bin/npm

Personally, before I deleted those, two of my user accounts were using the latest version of node/npm installed correctly via nvm, while a third account of mine remained stubborn by still using a far older installation of both node and npm apparently located inside my /usr/local/bin/ directory. As soon as I deleted both of them with the two above commands, that problematic user account implicitly began running the correct installation, having all three accounts mutually the intended versions.

(Implemented while using Centos 7 Blank x64. Some source code used above was originally supplied by 'phoenixNAP Global IT services' 1)

Another way to continue with the example @nfreeze used is this validation method:

UserModel.schema.path('name').validate(function (value, res) {
    UserModel.findOne({name: value}, 'id', function(err, user) {
        if (err) return res(err);
        if (user) return res(false);
        res(true);
    });
}, 'already exists');

TEXT is used for large pieces of string data. If the length of the field exceeed a certain threshold, the text is stored out of row.

VARCHAR is always stored in row and has a limit of 8000 characters. If you try to create a VARCHAR(x), where x > 8000, you get an error:

Server: Msg 131, Level 15, State 3, Line 1

The size () given to the type ‘varchar’ exceeds the maximum allowed for any data type (8000)

These length limitations do not concern VARCHAR(MAX) in SQL Server 2005, which may be stored out of row, just like TEXT.

Note that MAX is not a kind of constant here, VARCHAR and VARCHAR(MAX) are very different types, the latter being very close to TEXT.

In prior versions of SQL Server you could not access the TEXT directly, you only could get a TEXTPTR and use it in READTEXT and WRITETEXT functions.

In SQL Server 2005 you can directly access TEXT columns (though you still need an explicit cast to VARCHAR to assign a value for them).

TEXT is good:

• If you need to store large texts in your database
• If you do not search on the value of the column
• If you select this column rarely and do not join on it.

VARCHAR is good:

• If you store little strings
• If you search on the string value
• If you always select it or use it in joins.

By selecting here I mean issuing any queries that return the value of the column.

By searching here I mean issuing any queries whose result depends on the value of the TEXT or VARCHAR column. This includes using it in any JOIN or WHERE condition.

As the TEXT is stored out of row, the queries not involving the TEXT column are usually faster.

Some examples of what TEXT is good for:

• Blog comments
• Wiki pages
• Code source

Some examples of what VARCHAR is good for:

• Usernames
• Page titles
• Filenames

As a rule of thumb, if you ever need you text value to exceed 200 characters AND do not use join on this column, use TEXT.

Otherwise use VARCHAR.

P.S. The same applies to UNICODE enabled NTEXT and NVARCHAR as well, which you should use for examples above.

P.P.S. The same applies to VARCHAR(MAX) and NVARCHAR(MAX) that SQL Server 2005+ uses instead of TEXT and NTEXT. You'll need to enable large value types out of row for them with sp_tableoption if you want them to be always stored out of row.

As mentioned above and here, TEXT is going to be deprecated in future releases:

The text in row option will be removed in a future version of SQL Server. Avoid using this option in new development work, and plan to modify applications that currently use text in row. We recommend that you store large data by using the varchar(max), nvarchar(max), or varbinary(max) data types. To control in-row and out-of-row behavior of these data types, use the large value types out of row option.

I have written a shell script which will read data from properties file and then run mysql script on shell script. sharing this may help to others.

#!/bin/bash

       PROP_KEY=$1
       PROP_VALUE=`cat $PROPERTY_FILE | grep "$PROP_KEY" | cut -d'=' -f2`
       echo $PROP_VALUE
    }

    echo "# Reading property from $PROPERTY_FILE"
    DB_USER=$(getProperty "db.username")
    DB_PASS=$(getProperty "db.password")

controller_path holds the path of the controller used to serve the current view. (ie: admin/settings).

and

controller_name holds the name of the controller used to serve the current view. (ie: settings).

Swift 3

let secondviewController:UIViewController =  self.storyboard?.instantiateViewController(withIdentifier: "StoryboardIdOfsecondviewController") as? SecondViewController

self.navigationController?.pushViewController(secondviewController, animated: true)

Another example if you are using Titanium Alloy:

 collection.fetch({ 
     data: {
             where : JSON.stringify({
                page: 1
             })
           } 
      });

If you can create a numbers table, that contains numbers from 1 to the maximum fields to split, you could use a solution like this:

select
  tablename.id,
  SUBSTRING_INDEX(SUBSTRING_INDEX(tablename.name, ',', numbers.n), ',', -1) name
from
  numbers inner join tablename
  on CHAR_LENGTH(tablename.name)
     -CHAR_LENGTH(REPLACE(tablename.name, ',', ''))>=numbers.n-1
order by
  id, n

Please see fiddle here.

If you cannot create a table, then a solution can be this:

select
  tablename.id,
  SUBSTRING_INDEX(SUBSTRING_INDEX(tablename.name, ',', numbers.n), ',', -1) name
from
  (select 1 n union all
   select 2 union all select 3 union all
   select 4 union all select 5) numbers INNER JOIN tablename
  on CHAR_LENGTH(tablename.name)
     -CHAR_LENGTH(REPLACE(tablename.name, ',', ''))>=numbers.n-1
order by
  id, n

an example fiddle is here.

Try making the field names legal by removing spaces. It's a long shot but it has actually helped me before.

You can do this by using asynchronous Javascript SDK provided by facebook

Have a look at the following code

FB Javascript SDK initialization

<div id="fb-root"></div>
<script>
window.fbAsyncInit = function() {
FB.init({appId: 'YOUR APP ID', status: true, cookie: true,
xfbml: true});
};
(function() {
var e = document.createElement('script'); e.async = true;
e.src = document.location.protocol +
'//connect.facebook.net/en_US/all.js';
document.getElementById('fb-root').appendChild(e);
}());
</script>

Note: Remember to replace YOUR APP ID with your facebook AppId. If you don't have facebook AppId and you don't know how to create please check this

Add JQuery Library, I would preferred Google Library

<script src="//ajax.googleapis.com/ajax/libs/jquery/1.6.1/jquery.min.js" type="text/javascript"></script>

Add share dialog box (You can customize this dialog box by setting up parameters

<script type="text/javascript">
$(document).ready(function(){
$('#share_button').click(function(e){
e.preventDefault();
FB.ui(
{
method: 'feed',
name: 'This is the content of the "name" field.',
link: 'http://www.groupstudy.in/articlePost.php?id=A_111213073144',
picture: 'http://www.groupstudy.in/img/logo3.jpeg',
caption: 'Top 3 reasons why you should care about your finance',
description: "What happens when you don't take care of your finances? Just look at our country -- you spend irresponsibly, get in debt up to your eyeballs, and stress about how you're going to make ends meet. The difference is that you don't have a glut of taxpayers…",
message: ""
});
});
});
</script>

Now finally add image button

<img src = "share_button.png" id = "share_button">

A couple of things to note:

1. Non-JavaScript enabled clients won't be able to submit your form
2. The w3c specification does not allow nested forms in HTML - you'll potentially find that the action and method tags are ignored for this form in modern browsers, and that other ASP.NET controls no longer post-back correctly (as their form has been closed).

If you want it to be treated as a proper ASP.NET postback, you can call the methods supplied by the framework, namely __doPostBack(eventTarget, eventArgument):

<div name="mysubmitbutton" id="mysubmitbutton" class="customButton"
     onclick="javascript:__doPostBack('<%=mysubmitbutton.ClientID %>', 'MyCustomArgument');">
  Button Text
</div>

for IE9 I found that a meta tag was required to set the mode

<meta http-equiv="X-UA-Compatible" content="IE=Edge"/>

<video width="400" height="300" preload controls>
<source src="movie.mp4" type="video/mp4" />
Your browser does not support the video tag
</video>

You need to do two things:

1. Rename and re-order the factor levels before the plot
2. Rename the title of each legend to the same title

The code:

dtt$model <- factor(dtt$model, levels=c("mb", "ma", "mc"), labels=c("MBB", "MAA", "MCC"))

library(ggplot2)
ggplot(dtt, aes(x=year, y=V, group = model, colour = model, ymin = lower, ymax = upper)) +
  geom_ribbon(alpha = 0.35, linetype=0)+ 
  geom_line(aes(linetype=model), size = 1) +       
  geom_point(aes(shape=model), size=4)  +      
  theme(legend.position=c(.6,0.8)) +
  theme(legend.background = element_rect(colour = 'black', fill = 'grey90', size = 1, linetype='solid')) +
  scale_linetype_discrete("Model 1") +
  scale_shape_discrete("Model 1") +
  scale_colour_discrete("Model 1")

However, I think this is really ugly as well as difficult to interpret. It's far better to use facets:

ggplot(dtt, aes(x=year, y=V, group = model, colour = model, ymin = lower, ymax = upper)) +
  geom_ribbon(alpha=0.2, colour=NA)+ 
  geom_line() +       
  geom_point()  +      
  facet_wrap(~model)

An option for delegates in C++ that is not otherwise mentioned here is to do it C style using a function ptr and a context argument. This is probably the same pattern that many asking this question are trying to avoid. But, the pattern is portable, efficient, and is usable in embedded and kernel code.

class SomeClass
{
    in someMember;
    int SomeFunc( int);

    static void EventFunc( void* this__, int a, int b, int c)
    {
        SomeClass* this_ = static_cast< SomeClass*>( this__);

        this_->SomeFunc( a );
        this_->someMember = b + c;
    }
};

void ScheduleEvent( void (*delegateFunc)( void*, int, int, int), void* delegateContext);

    ...
    SomeClass* someObject = new SomeObject();
    ...
    ScheduleEvent( SomeClass::EventFunc, someObject);
    ...

In simple words, strace traces all system calls issued by a program along with their return codes. Think things such as file/socket operations and a lot more obscure ones.

It is most useful if you have some working knowledge of C since here system calls would more accurately stand for standard C library calls.

Let's say your program is /usr/local/bin/cough. Simply use:

strace /usr/local/bin/cough <any required argument for cough here>

or

strace -o <out_file> /usr/local/bin/cough <any required argument for cough here>

to write into 'out_file'.

All strace output will go to stderr (beware, the sheer volume of it often asks for a redirection to a file). In the simplest cases, your program will abort with an error and you'll be able to see what where its last interactions with the OS in strace output.

More information should be available with:

man strace

Shift-tab doesn't seem to work on multi-lines in Aptana. It also doesn't work on single lines with a single preceding space. Any workarounds? I use shift-tab (outdent) to fix badly formatted code all the time.

I miss NetBeans ...

UPDATE: it works on multi-newlines, if the multi-lines have the same level of indentation. It should just continue outdenting the other lines that haven't reached the beginning of the new line yet. Is there an option to change this I wonder?

You have to drop the foreign key. Foreign keys in MySQL automatically create an index on the table (There was a SO Question on the topic).

ALTER TABLE mytable DROP FOREIGN KEY mytable_ibfk_1 ; 

The double \ should work for Windows, but you still need to take care of the folders you mention in your path. All of them (exept the filename) must exist. otherwise you will get an error.

You can use cut with a delimiter like this:

with space delim:

cut -d " " -f1-100,1000-1005 infile.csv > outfile.csv

with tab delim:

cut -d$'\t' -f1-100,1000-1005 infile.csv > outfile.csv

I gave you the version of cut in which you can extract a list of intervals...

Hope it helps!

With Swift 3, when you want to filter an array of dictionaries with a predicate based on dictionary keys and values, you may choose one of the following patterns.

#1. Using NSPredicate init(format:arguments:) initializer

If you come from Objective-C, init(format:arguments:) offers a key-value coding style to evaluate your predicate.

Usage:

import Foundation

let array = [["key1": "value1", "key2": "value2"], ["key1": "value3"], ["key3": "value4"]]

let predicate = NSPredicate(format: "key1 == %@", "value1")
//let predicate = NSPredicate(format: "self['key1'] == %@", "value1") // also works
let filteredArray = array.filter(predicate.evaluate)

print(filteredArray) // prints: [["key2": "value2", "key1": "value1"]]

#2. Using NSPredicate init(block:) initializer

As an alternative if you prefer strongly typed APIs over stringly typed APIs, you can use init(block:) initializer.

Usage:

import Foundation

let array = [["key1": "value1", "key2": "value2"], ["key1": "value3"], ["key3": "value4"]]

let dictPredicate = NSPredicate(block: { (obj, _) in
    guard let dict = obj as? [String: String], let value = dict["key1"] else { return false }
    return value == "value1"
})

let filteredArray = array.filter(dictPredicate.evaluate)
print(filteredArray) // prints: [["key2": "value2", "key1": "value1"]]

Go to the first line from which you would like to delete, and press the keys dG

If you look at the output you receive from print() and also in your Traceback, you'll see the value you get back is not a string, it's a bytes object (prefixed by b):

b'{\n  "note":"This file    .....

If you fetch the URL using a tool such as curl -v, you will see that the content type is

Content-Type: application/json; charset=utf-8

So it's JSON, encoded as UTF-8, and Python is considering it a byte stream, not a simple string. In order to parse this, you need to convert it into a string first.

Change the last line of code to this:

info = json.loads(js.decode("utf-8"))

For Rails 4.x the log level is configured a bit different than in Rails 3.x

Add this to config/environment/test.rb

# Enable stdout logger
config.logger = Logger.new(STDOUT)

# Set log level
config.log_level = :ERROR

The logger level is set on the logger instance from config.log_level at: https://github.com/rails/rails/blob/v4.2.4/railties/lib/rails/application/bootstrap.rb#L70

Environment variable

As a bonus, you can allow overwriting the log level using an environment variable with a default value like so:

# default :ERROR
config.log_level = ENV.fetch("LOG_LEVEL", "ERROR")

And then running tests from shell:

# Log level :INFO (the value is uppercased in bootstrap.rb)
$ LOG_LEVEL=info rake test

# Log level :ERROR
$ rake test

The difference between these two approaches is as follows:

Synchronous way: It waits for each operation to complete, after that only it executes the next operation. For your query: The console.log() command will not be executed until & unless the query has finished executing to get all the result from Database.

Asynchronous way: It never waits for each operation to complete, rather it executes all operations in the first GO only. The result of each operation will be handled once the result is available. For your query: The console.log() command will be executed soon after the Database.Query() method. While the Database query runs in the background and loads the result once it is finished retrieving the data.

Use cases

1. If your operations are not doing very heavy lifting like querying huge data from DB then go ahead with Synchronous way otherwise Asynchronous way.

2. In Asynchronous way you can show some Progress indicator to the user while in background you can continue with your heavy weight works. This is an ideal scenario for GUI apps.

My English is not good so I'll just write a simple example here.

    double a = 0.02;
    double b = 0.03;
    double c = b - a;
    System.out.println(c);

    BigDecimal _a = new BigDecimal("0.02");
    BigDecimal _b = new BigDecimal("0.03");
    BigDecimal _c = _b.subtract(_a);
    System.out.println(_c);

Program output:

0.009999999999999998
0.01

Somebody still want to use double? ;)

I had a similar problem and used

@-webkit-keyframes pan {
   0%, 10%       { -webkit-transform: translate3d( 0%, 0px, 0px); }
   90%, 100%     { -webkit-transform: translate3d(-50%, 0px, 0px); }
}

Bit irritating that you have to fake your duration to account for 'delays' at either end.

Other solutions are good enough to answer your query. However, if you are looking for just one command to do that for you -

Create a file name "run", in directory where your Java files are. And save this in your file -

javac "$1.java"
if [ $? -eq 0 ]; then
  echo "--------Run output-------"
  java "$1"
fi

give this file run permission by running -

chmod 777 

Now you can run any of your files by merely running -

./run <yourfilename> (don't add .java in filename)

It's working fine for me by the following way -

public async Task<object> TestMethod(TestModel model)
    {
        try
        {
            var apicallObject = new
            {
                Id= model.Id,
                name= model.Name
            };

            if (apicallObject != null)
            {
                var bodyContent = JsonConvert.SerializeObject(apicallObject);
                using (HttpClient client = new HttpClient())
                {
                    var content = new StringContent(bodyContent.ToString(), Encoding.UTF8, "application/json");
                    content.Headers.ContentType = new MediaTypeHeaderValue("application/json");
                    client.DefaultRequestHeaders.Add("access-token", _token); // _token = access token
                    var response = await client.PostAsync(_url, content); // _url =api endpoint url
                    if (response != null)
                    {
                        var jsonString = await response.Content.ReadAsStringAsync();

                        try
                        {
                            var result = JsonConvert.DeserializeObject<TestModel2>(jsonString); // TestModel2 = deserialize object
                        }
                        catch (Exception e){
                            //msg
                            throw e;
                        }
                    }
                }
            }
        }
        catch (Exception ex)
        {
            throw ex;
        }
        return null;
    }

It's because the iterable is

(x > 0 for x in list)

Note that x > 0 returns either True or False and thus you have an iterable of booleans.

NEW_VAR=""
if [[ ${ENV_VAR} && ${ENV_VAR-x} ]]; then
  NEW_VAR=${ENV_VAR}
else
  NEW_VAR="new value"
fi

You can use the difference between references and pointers if you follow a convention for arguments passed to a function. Const references are for data passed into a function, and pointers are for data passed out of a function. In other languages, you can explicit notate this with keywords such as in and out. In C++, you can declare (by convention) the equivalent. For example,

void DoSomething(const Foo& thisIsAnInput, Foo* thisIsAnOutput)
{
   if (thisIsAnOuput)
      *thisIsAnOutput = thisIsAnInput;
}

The use of references as inputs and pointers as outputs is part of the Google style guide.

Use for...in loop:

for (var key in obj) {
   console.log(' name=' + key + ' value=' + obj[key]);

   // do some more stuff with obj[key]
}

That will be (for you very specific example)

ActiveWorkbook.worksheets("Sheet2").cells(aRow,aCol).Value=someval

OR

someVal=ActiveWorkbook.worksheets("Sheet2").cells(aRow,aCol).Value

So get a F1 click and read about Worksheets collection, which contains Worksheet objects, which in turn has a Cells collection, holding Cell objects...

Java uses double quotes for "String" and single quotes for 'C'haracters.

A bit too late with this answer, but since I faced a similar question, I made a test with JMeter and a MySQL server on same machine, where I have used:

1. A transaction Controller (generating parent sample) that contained two JDBC Requests: a Delete and an Insert statement
2. A sepparate JDBC Request containing the Update statement.

After running the test for 500 loops, I have obtained the following results:

DEL + INSERT - Average: 62ms

Update - Average: 30ms

Results:

I was able to fix this issue by changing $(document).ready() to window.onLoad().

This is the solution i found.

https://github.com/aspnet/EntityFramework.Docs/blob/master/entity-framework/core/miscellaneous/configuring-dbcontext.md

Configure DBContext via AddDbContext

public void ConfigureServices(IServiceCollection services)
{
    services.AddDbContext<BloggingContext>(options => options.UseSqlite("Data Source=blog.db"));
}

Add new constructor to your DBContext class

public class BloggingContext : DbContext
{
    public BloggingContext(DbContextOptions<BloggingContext> options)
      :base(options)
    { }

    public DbSet<Blog> Blogs { get; set; }
}

Inject context to your controllers

public class MyController
{
    private readonly BloggingContext _context;

    public MyController(BloggingContext context)
    {
      _context = context;
    }

    ...
}

From the Java Tutorial:

A stream is a sequence of data.

A program uses an input stream to read data from a source, one item at a time:

A program uses an output stream to write data to a destination, one item at time:

The data source and data destination pictured above can be anything that holds, generates, or consumes data. Obviously this includes disk files, but a source or destination can also be another program, a peripheral device, a network socket, or an array.

Sample code from oracle tutorial:

import java.io.FileInputStream;
import java.io.FileOutputStream;
import java.io.IOException;

public class CopyBytes {
    public static void main(String[] args) throws IOException {

        FileInputStream in = null;
        FileOutputStream out = null;

        try {
            in = new FileInputStream("xanadu.txt");
            out = new FileOutputStream("outagain.txt");
            int c;

            while ((c = in.read()) != -1) {
                out.write(c);
            }
        } finally {
            if (in != null) {
                in.close();
            }
            if (out != null) {
                out.close();
            }
        }
    }
}

This program uses byte streams to copy xanadu.txt file to outagain.txt , by writing one byte at a time

Have a look at this SE question to know more details about advanced Character streams, which are wrappers on top of Byte Streams :

byte stream and character stream

You can use Timer

Timer timer = new Timer();

timer.schedule( new TimerTask() {
    public void run() {
       // do your work 
    }
 }, 0, 60*1000);

When the times comes

  timer.cancel();

To shut it down.

1. Navigate REGEDIT to HKEY_LOCAL_MACHINE\SOFTWARE\Classes\Microsoft.PowerShellScript.1\Shell
2. On the right pane, double-click "(Default)"
3. Delete existing value of "Open" (which launches Notepad) and type "0" (being zero, which launches Powershell directly).

Revert the value if you wish to use Notepad as the default again.

Git will not store the password when you use URLs like that. Instead, it will just store the username, so it only needs to prompt you for the password the next time. As explained in the manual, to store the password, you should use an external credential helper. For Windows, you can use the Windows Credential Store for Git. This helper is also included by default in GitHub for Windows.

When using it, your password will automatically be remembered, so you only need to enter it once. So when you clone, you will be asked for your password, and then every further communication with the remote will not prompt you for your password again. Instead, the credential helper will provide Git with the authentication.

This of course only works for authentication via https; for ssh access ([email protected]/repository.git) you use SSH keys and those you can remember using ssh-agent (or PuTTY’s pageant if you’re using plink).

You can loop through the cells of any column in a table by knowing just its name and not its position. If the table is in sheet1 of the workbook:

Dim rngCol as Range
Dim cl as Range
Set rngCol = Sheet1.Range("TableName[ColumnName]")
For Each cl in rngCol
    cl.Value = "PHEV"
Next cl

The code above will loop through the data values only, excluding the header row and the totals row. It is not necessary to specify the number of rows in the table.

Use this to find the location of any column in a table by its column name:

Dim colNum as Long
colNum = Range("TableName[Column name to search for]").Column

This returns the numeric position of a column in the table.

See I did what I thought was the obvious thing was:

string filePath = ConfigurationManager.AppSettings.GetValues("ClientsFilePath").ToString();

While that compiles it always returns null.

This however (from above) works:

string filePath = ConfigurationManager.AppSettings["ClientsFilePath"];

You can use validDate.setTime(strDate) Have a look at the javadoc at http://docs.oracle.com/javase/1.5.0/docs/api/java/util/Calendar.html

You can always do

git clone git://repo.org/fossproject.git && rm -rf fossproject/.git

body { 
        background: url("../img/debut_dark.png") no-repeat center center fixed;
    }

Worked for me.

As ams said above, don't take a pointer to a member of a struct that's packed. This is simply playing with fire. When you say __attribute__((__packed__)) or #pragma pack(1), what you're really saying is "Hey gcc, I really know what I'm doing." When it turns out that you do not, you can't rightly blame the compiler.

Perhaps we can blame the compiler for it's complacency though. While gcc does have a -Wcast-align option, it isn't enabled by default nor with -Wall or -Wextra. This is apparently due to gcc developers considering this type of code to be a brain-dead "abomination" unworthy of addressing -- understandable disdain, but it doesn't help when an inexperienced programmer bumbles into it.

Consider the following:

struct  __attribute__((__packed__)) my_struct {
    char c;
    int i;
};

struct my_struct a = {'a', 123};
struct my_struct *b = &a;
int c = a.i;
int d = b->i;
int *e __attribute__((aligned(1))) = &a.i;
int *f = &a.i;

Here, the type of a is a packed struct (as defined above). Similarly, b is a pointer to a packed struct. The type of of the expression a.i is (basically) an int l-value with 1 byte alignment. c and d are both normal ints. When reading a.i, the compiler generates code for unaligned access. When you read b->i, b's type still knows it's packed, so no problem their either. e is a pointer to a one-byte-aligned int, so the compiler knows how to dereference that correctly as well. But when you make the assignment f = &a.i, you are storing the value of an unaligned int pointer in an aligned int pointer variable -- that's where you went wrong. And I agree, gcc should have this warning enabled by default (not even in -Wall or -Wextra).

String::repeat

Use String::repeat in Java 11 and later.

Examples

"A".repeat( 3 ) 

AAA

And the example from the Question.

int i = 3; //frequency to repeat
String someNum = "123"; // initial string
String ch = "0"; // character to append

someNum = someNum + ch.repeat(i); // formulation of the string
System.out.println(someNum); // would result in output -- "123000"

it took me a long time to figure out how to do this without having to loop through all the records. I have a bound datagridview-source, and all fields are bound except for the checkbox-column. So I don't have/need a loop to add each row and I didn't want to create one just for this purpuse. So after a lot of trying I finally got it. And it's actually very simple too:

First you add a new .cs File to your project with a custom-checkbox cell, e.g.

DataGridViewCheckboxCellFilter.cs:

using System.Windows.Forms;

namespace MyNamespace {
    public class DataGridViewCheckboxCellFilter : DataGridViewCheckBoxCell {
        public DataGridViewCheckboxCellFilter() : base() {
            this.FalseValue = 0;
            this.TrueValue = 1;
            this.Value = TrueValue;
        }
    }
}

After this, on your GridView, where you add the checkbox-column, you do:

// add checkboxes
DataGridViewCheckBoxColumn col_chkbox = new DataGridViewCheckBoxColumn();
{
    col_chkbox.HeaderText = "X";
    col_chkbox.Name = "checked";
    col_chkbox.CellTemplate = new DataGridViewCheckboxCellFilter();                
}
this.Columns.Add(col_chkbox);

And that's it! Everytime your checkboxes get added in a new row, they'll be set to true. Enjoy!

The answer is no. Keep in mind that in both cases, mdDate.Kind = DateTimeKind.Unspecified.

Therefore it may be better to do the following:

DateTime myDate = new DateTime(1, 1, 1, 0, 0, 0, DateTimeKind.Utc);

The myDate.Kind property is readonly, so it cannot be changed after the constructor is called.

In addition to @chanafdo answer, you can use route name

when working with laravel blade

<a href="{{route('login')}}">login here</a> with parameter in route name

when go to url like URI: profile/{id} <a href="{{route('profile', ['id' => 1])}}">login here</a>

without blade

<a href="<?php echo route('login')?>">login here</a>

with parameter in route name

when go to url like URI: profile/{id} <a href="<?php echo route('profile', ['id' => 1])?>">login here</a>

As of laravel 5.2 you can use @php @endphp to create as <?php ?> in laravel blade. Using blade your personal opinion but I suggest to use it. Learn it. It has many wonderful features as template inheritance, Components & Slots,subviews etc...

Running IIS 7.5, I had luck adding permissions for the local computer user IUSR. The app pool user didn't work.

When to use target='_blank' :

The HTML version (Some devices not support it):

<a href="http://chriscoyier.net" target="_blank">This link will open in new window/tab</a>

The JavaScript version for all Devices :

The use of rel="external" is perfectly valid

<script type="text/javascript" src="http://ajax.googleapis.com/ajax/libs/jquery/1.3.2/jquery.min.js"></script>
<script type="text/javascript">
    $('a[rel="external"]').attr('target', '_blank');
</script>

and for Jquery can try with the below one:

$("#content a[href^='http://']").attr("target","_blank");

If browser setting don't allow you to open in new windows :

href = "google.com";
onclick="window.open (this.href, ''); return false";

Mutable and immutable are English words meaning "can change" and "cannot change" respectively. The meaning of the words is the same in the IT context; i.e.

• a mutable string can be changed, and
• an immutable string cannot be changed.

The meanings of these words are the same in C# / .NET as in other programming languages / environments, though (obviously) the names of the types may differ, as may other details.

For the record:

• String is the standard C# / .Net immutable string type
• StringBuilder is the standard C# / .Net mutable string type

To "effect a change" on a string represented as a C# String, you actually create a new String object. The original String is not changed ... because it is unchangeable.

In most cases it is better to use String because it is easier reason about them; e.g. you don't need to consider the possibility that some other thread might "change my string".

However, when you need to construct or modify a string using a sequence of operations, it may be more efficient to use a StringBuilder. An example is when you are concatenating many string fragments to form a large string:

• If you do this as a sequence of String concatenations, you copy O(N^2) characters, where N is the number of component strings.
• If use a StringBuilder you only copy O(N) characters.

And finally, for those people who assert that a StringBuilder is not a string because it is not immutable, the Microsoft documentation describes StringBuilder thus:

"Represents a mutable string of characters. This class cannot be inherited."

Building further on Aydin's and Todd's answers, here is an extension method that also lets you get the name from a resource file

using AppResources;
using System;
using System.ComponentModel.DataAnnotations;
using System.Linq;
using System.Reflection;
using System.Resources;

public static class EnumExtensions
{
    public static string GetDisplayName(this Enum enumValue)
    {
        var enumMember= enumValue.GetType()
                        .GetMember(enumValue.ToString());

        DisplayAttribute displayAttrib = null;
        if (enumMember.Any()) {
            displayAttrib = enumMember 
                        .First()
                        .GetCustomAttribute<DisplayAttribute>();
        }

        string name = null;
        Type resource = null;

        if (displayAttrib != null)
        {
            name = displayAttrib.Name;
            resource = displayAttrib.ResourceType;
        }

        return String.IsNullOrEmpty(name) ? enumValue.ToString()
            : resource == null ?  name
            : new ResourceManager(resource).GetString(name);
    }
}

and use it like

public enum Season 
{
    [Display(ResourceType = typeof(Resource), Name = Season_Summer")]
    Summer
}

I am guessing there is a fundamental reason for the change, it isn't merely cosmetic to make the old interpretation clearer: that reason is concurrency. Unspecified order of elaboration is merely selection of one of several possible serial orderings, this is quite different to before and after orderings, because if there is no specified ordering, concurrent evaluation is possible: not so with the old rules. For example in:

f (a,b)

previously either a then b, or, b then a. Now, a and b can be evaluated with instructions interleaved or even on different cores.

xsd.exe does not work well when you have circular references (ie a type can own an element of its own type directly or indirectly).

When circular references exist, I use Xsd2Code. Xsd2Code handles circular references well and works within the VS IDE, which is a big plus. It also has a lot of features you can use like generating the serialization/deserialization code. Make sure you turn on the GenerateXMLAttributes if you are generating serialization though (otherwise you'll get exceptions for ordering if not defined on all elements).

Neither works well with the choice feature. you'll end up with lists/collections of object instead of the type you want. I'd recommend avoiding choice in your xsd if possible as this does not serialize/deserialize well into a strongly typed class. If you don't care about this, though, then it's not a problem.

The any feature in xsd2code deserializes as System.Xml.XmlElement which I find really convenient but may be an issue if you want strong typed objects. I often use any when allowing custom config data, so an XmlElement is convenient to pass to another XML deserializer that is custom defined elsewhere.

Here is a working example, the red links can't be right clicked anymore.

$("ul.someLinks1 a").each(function(i, obj) {_x000D_
_x000D_
  $(obj).on("contextmenu",function(){_x000D_
     return false;_x000D_
  }); _x000D_
  _x000D_
  $(obj).css("color", "red");_x000D_
});

<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>_x000D_
<ul class="someLinks1">_x000D_
  <li><a href="www.google.de">google</a></li>_x000D_

In sproc, you can use the following condition:

php.net manual has a few solid explanation and examples contributed by users of what stdClass is, I especially like this one http://php.net/manual/en/language.oop5.basic.php#92123, https://stackoverflow.com/a/1434375/2352773.

stdClass is the default PHP object. stdClass has no properties, methods or parent. It does not support magic methods, and implements no interfaces.

When you cast a scalar or array as Object, you get an instance of stdClass. You can use stdClass whenever you need a generic object instance.

stdClass is NOT a base class! PHP classes do not automatically inherit from any class. All classes are standalone, unless they explicitly extend another class. PHP differs from many object-oriented languages in this respect.

You could define a class that extends stdClass, but you would get no benefit, as stdClass does nothing.

import javax.xml.bind.DatatypeConverter;

public class f{

   public static void main(String a[]){

      String str = new String(DatatypeConverter.printBase64Binary(new String("user:123").getBytes()));
      String res = DatatypeConverter.parseBase64Binary(str);
      System.out.println(res);
   }
}

In my case I get the same error title could not resolve all dependencies for configuration

However suberror said, it was due to a linting jar not loaded with its url given saying status 502 received, I ran the deployment command again, this time it succeeded.

Titleize will capitalise every word. This line feels hefty, but will guarantee that the only letter changed is the first one.

new_string = string.slice(0,1).capitalize + string.slice(1..-1)

Update:

irb(main):001:0> string = "i'm from New York..."
=> "i'm from New York..."
irb(main):002:0> new_string = string.slice(0,1).capitalize + string.slice(1..-1)
=> "I'm from New York..."

You can see if the file is locked by trying to read or lock it yourself first.

Please see my answer here for more information.

                                            new ContactNumber("555-5678") };

You can save it as .txt and change it manually using a mouse click and your keyboard. OR, when saving the file:

• choose All types(*.*) in the Save as type field.
• type filename.json in File name field

So appearantly many seems to have had this issue (me including) and I found the fault to be that Tkinter wasn't installed on my system when python was compiled.

This post describes how to solve the problem by:

1. Removing the virtual environment/python distribution
2. install Tkinter with sudo apt-get install tk-dev (for deb) or sudo pacman -S tk (for arch/manjaro)
3. Then proceed to compile python again.

This worked wonders for me.

Try this code. it worked for me.

 function getInvoiceID(url, invoiceId) {
    return $.ajax({
        type: 'POST',
        url: url,
        data: { invoiceId: invoiceId },
        async: false,
    });
}
function isInvoiceIdExists(url, invoiceId) {
    $.when(getInvoiceID(url, invoiceId)).done(function (data) {
        if (!data) {

        }
    });
}

Actually... you can't use a simple regex here, at least not one. You probably need to worry about comments! Someone may write:

<!-- <content> blah </content> -->

You can take two approaches here:

1. Strip all comments out first. Then use the regex approach.
2. Do not use regular expressions and use a context sensitive parsing approach that can keep track of whether or not you are nested in a comment.

Be careful.

I am also not so sure you can match all new lines at once. @Quartz suggested this one:

<content>([^\n]*\n+)+</content>

This will match any content tags that have a newline character RIGHT BEFORE the closing tag... but I'm not sure what you mean by matching all newlines. Do you want to be able to access all the matched newline characters? If so, your best bet is to grab all content tags, and then search for all the newline chars that are nested in between. Something more like this:

<content>.*</content>

BUT THERE IS ONE CAVEAT: regexes are greedy, so this regex will match the first opening tag to the last closing one. Instead, you HAVE to suppress the regex so it is not greedy. In languages like python, you can do this with the "?" regex symbol.

I hope with this you can see some of the pitfalls and figure out how you want to proceed. You are probably better off using an XML parsing library, then iterating over all the content tags.

I know I may not be offering the best solution, but at least I hope you will see the difficulty in this and why other answers may not be right...

UPDATE 1:

Let me summarize a bit more and add some more detail to my response. I am going to use python's regex syntax because it is what I am more used to (forgive me ahead of time... you may need to escape some characters... comment on my post and I will correct it):

To strip out comments, use this regex: Notice the "?" suppresses the .* to make it non-greedy.

Similarly, to search for content tags, use: .*?

Also, You may be able to try this out, and access each newline character with the match objects groups():

<content>(.*?(\n))+.*?</content>

I know my escaping is off, but it captures the idea. This last example probably won't work, but I think it's your best bet at expressing what you want. My suggestion remains: either grab all the content tags and do it yourself, or use a parsing library.

UPDATE 2:

So here is python code that ought to work. I am still unsure what you mean by "find" all newlines. Do you want the entire lines? Or just to count how many newlines. To get the actual lines, try:

#!/usr/bin/python

import re

def FindContentNewlines(xml_text):
    # May want to compile these regexes elsewhere, but I do it here for brevity
    comments = re.compile(r"<!--.*?-->", re.DOTALL)
    content = re.compile(r"<content>(.*?)</content>", re.DOTALL)
    newlines = re.compile(r"^(.*?)$", re.MULTILINE|re.DOTALL)

    # strip comments: this actually may not be reliable for "nested comments"
    # How does xml handle <!--  <!-- --> -->. I am not sure. But that COULD
    # be trouble.
    xml_text = re.sub(comments, "", xml_text)

    result = []
    all_contents = re.findall(content, xml_text)
    for c in all_contents:
        result.extend(re.findall(newlines, c))

    return result

if __name__ == "__main__":
    example = """

<!-- This stuff
ought to be omitted
<content>
  omitted
</content>
-->

This stuff is good
<content>
<p>
  haha!
</p>
</content>

This is not found
"""
    print FindContentNewlines(example)

This program prints the result:

 ['', '<p>', '  haha!', '</p>', '']

The first and last empty strings come from the newline chars immediately preceeding the first <p> and the one coming right after the </p>. All in all this (for the most part) does the trick. Experiment with this code and refine it for your needs. Print out stuff in the middle so you can see what the regexes are matching and not matching.

Hope this helps :-).

PS - I didn't have much luck trying out my regex from my first update to capture all the newlines... let me know if you do.

My first answer!

This will set the safemode switch:

bcdedit /set {current} safeboot minimal 

with networking:

bcdedit /set {current} safeboot network

then reboot the machine with

shutdown /r

to put back in normal mode via dos:

bcdedit /deletevalue {current} safeboot

Just to make the answer of Nae a little bit more elaborate, here is a full blown example which includes the possibility to pass a variable to the callback which contains different values for each button:

import tkinter as tk
    
def callback(text):
    print(text)

top = tk.Tk()
Texts=["text1", "text2", "text3"]
Buttons=[]

for i, z in enumerate(Texts):
    Buttons.append(tk.Button(top, text=z, command= lambda ztemp=z : callback(ztemp)))
    Buttons[i].pack(side=tk.LEFT, padx=5)

top.mainloop()

By defining a temporary variable ztemp, the value of that variable gets fixed at the moment when the button is defined.

Get is supposed to return, one and exactly one record, to fix this use filter(), and then take first element of the queryset returned to get the object you were expecting from get, also it would be useful to check if atleast one record is returned before taking out the first element to avoid IndexError

You can not do this directly. In standard WebForms JavaScript is interpreted by browser and C# by server. What you can do to call a method from server using JavaScript is.

• Use WebMethod as attribute in target methods.
• Add ScriptManager setting EnablePageMethods as true.
• Add JavaScript code to call the methods through the object PageMethods.

Like this:

Step 1

public partial class Products : System.Web.UI.Page 
{ 
    [System.Web.Services.WebMethod()] 
    [System.Web.Script.Services.ScriptMethod()] 
    public static List<Product> GetProducts(int cateogryID) 
    {
        // Put your logic here to get the Product list 
    }

Step 2: Adding a ScriptManager on the Page

<asp:ScriptManager ID="ScriptManager1" runat="server" EnablePageMethods="true" />

Step 3: Calling the method using JavaScript

function GetProductsByCategoryID(categoryID)
{
    PageMethods.GetProducts(categoryID, OnGetProductsComplete);
}

Take a look at this link.

To call a JavaScript function from server you can use RegisterStartupScript:

ClientScript.RegisterStartupScript(GetType(),"id","callMyJSFunction()",true);

var word = " testWord ";   //add here word or space and test

var x = $.trim(word);

if(x.length > 0)
    alert('word');
else
    alert('spaces');

Instead of using this in your current class setClassRoomName("aClassName"); you have to use classroom.setClassRoomName("aClassName");

You have to add the class' and at a point like

yourClassNameWhereTheMethodIs.theMethodsName();

I know it's a really late answer but if someone starts learning Java and randomly sees this post he knows what to do.

You can do one thing.

1. In the AppSettings.config (create one if doesn't exist), create a key value pair.
2. In the Code pull the value and convert it to Int32 and assign it to command.TimeOut.

like:- In appsettings.config ->

<appSettings>    
   <add key="SqlCommandTimeOut" value="240"/>
</appSettings>

In Code ->

command.CommandTimeout = Convert.ToInt32(System.Configuration.ConfigurationManager.AppSettings["SqlCommandTimeOut"]);

That should do it.

Note:- I faced most of the timeout issues when I used SqlHelper class from microsoft application blocks. If you have it in your code and are facing timeout problems its better you use sqlcommand and set its timeout as described above. For all other scenarios sqlhelper should do fine. If your client is ok with waiting a little longer than what sqlhelper class offers you can go ahead and use the above technique.

example:- Use this -

 SqlCommand cmd = new SqlCommand(completequery);

 cmd.CommandTimeout =  Convert.ToInt32(System.Configuration.ConfigurationManager.AppSettings["SqlCommandTimeOut"]);

 SqlConnection con = new SqlConnection(sqlConnectionString);
 SqlDataAdapter adapter = new SqlDataAdapter();
 con.Open();
 adapter.SelectCommand = new SqlCommand(completequery, con);
 adapter.Fill(ds);
 con.Close();

Instead of

DataSet ds = new DataSet();
ds = SqlHelper.ExecuteDataset(sqlConnectionString, CommandType.Text, completequery);

Update: Also refer to @Triynko answer below. It is important to check that too.

Android SDK implementation of FragmentTransaction wants an Animator while support library wants an Animation, don't ask me why but after strangeluk's comment I looked into android 4.0.3 code and support library. Android SDK uses loadAnimator() and support library uses loadAnimation()

I would rather use Last() from LINQ to do it.

rows = rows.Remove(rows.Last());

or

rows = rows.Remove(rows.LastOrDefault());

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

You can create the state in the ParentComponent using useState and pass down the setIsParentData function as prop into the ChildComponent.

In the ChildComponent, update the data using the received function through prop to send the data back to ParentComponent.

I use this technique especially when my code in the ParentComponent is getting too long, therefore I will create child components from the ParentComponent. Typically, it will be only 1 level down and using useContext or redux seems overkill in order to share states between components.

ParentComponent.js

import React, { useState } from 'react';
import ChildComponent from './ChildComponent';

export function ParentComponent(){
  const [isParentData, setIsParentData] = useState(True);

  return (
    <p>is this a parent data?: {isParentData}</p>
    <ChildComponent toChild={isParentData} sendToParent={setIsParentData} />
  );
}

ChildComponent.js

import React from 'react';

export function ChildComponent(props){

  return (
    <button onClick={() => {props.sendToParent(False)}}>Update</button>
    <p>The state of isParentData is {props.toChild}</p>
  );
};

JavaScript:

document.getElementsByTagName('head')[0].appendChild( ... );

Make DOM element like so:

link=document.createElement('link');
link.href='href';
link.rel='rel';

document.getElementsByTagName('head')[0].appendChild(link);
