Or if you want a simple one-liner:

Person person = JAXB.unmarshal(new StringReader("<?xml ..."), Person.class);

I know that it's an old question, but you can change the Response using a parameter (P):

public class Response<P> implements Serializable{

private static final long serialVersionUID = 1L;

public enum MessageCode {
    SUCCESS, ERROR, UNKNOWN
}

private MessageCode code;
private String message;
private P payload;

...
public P getPayload() {
    return payload;
}

public void setPayload(P payload) {
    this.payload = payload;
}

}

The method would be

public Response<Departments> getDepartments(){...}

I can't try it now but it should works.

Otherwise it's possible to extends Response

@XmlRootElement    
public class DepResponse extends Response<Department> {<no content>}

According to the release-notes, Java 11 removed the Java EE modules:

java.xml.bind (JAXB) - REMOVED

• Java 8 - OK
• Java 9 - DEPRECATED
• Java 10 - DEPRECATED
• Java 11 - REMOVED

See JEP 320 for more info.

You can fix the issue by using alternate versions of the Java EE technologies. Simply add Maven dependencies that contain the classes you need:

<dependency>
  <groupId>javax.xml.bind</groupId>
  <artifactId>jaxb-api</artifactId>
  <version>2.3.0</version>
</dependency>
<dependency>
  <groupId>com.sun.xml.bind</groupId>
  <artifactId>jaxb-core</artifactId>
  <version>2.3.0</version>
</dependency>
<dependency>
  <groupId>com.sun.xml.bind</groupId>
  <artifactId>jaxb-impl</artifactId>
  <version>2.3.0</version>
</dependency>

Jakarta EE 8 update (Mar 2020)

Instead of using old JAXB modules you can fix the issue by using Jakarta XML Binding from Jakarta EE 8:

<dependency>
  <groupId>jakarta.xml.bind</groupId>
  <artifactId>jakarta.xml.bind-api</artifactId>
  <version>2.3.3</version>
</dependency>
<dependency>
  <groupId>com.sun.xml.bind</groupId>
  <artifactId>jaxb-impl</artifactId>
  <version>2.3.3</version>
  <scope>runtime</scope>
</dependency>

Jakarta EE 9 update (Nov 2020)

Use latest release of Eclipse Implementation of JAXB 3.0.0:

• Jakarta EE9 API jakarta.xml.bind-api
• compatible implementation jaxb-impl

<dependency>
  <groupId>jakarta.xml.bind</groupId>
  <artifactId>jakarta.xml.bind-api</artifactId>
  <version>3.0.0</version>
</dependency>
<dependency>
  <groupId>com.sun.xml.bind</groupId>
  <artifactId>jaxb-impl</artifactId>
  <version>3.0.0</version>
  <scope>runtime</scope>
</dependency>

Note: Jakarta EE 9 adopts new API package namespace jakarta.xml.bind.*, so update import statements:

javax.xml.bind -> jakarta.xml.bind

There may be a valid reason why you want to do this, but generating this kind of XML is generally best avoided. Why? Because it means that the XML elements of your map are dependent on the runtime contents of your map. And since XML is usually used as an external interface or interface layer this is not desirable. Let me explain.

The Xml Schema (xsd) defines the interface contract of your XML documents. In addition to being able to generate code from the XSD, JAXB can also generate the XML schema for you from the code. This allows you to restrict the data exchanged over the interface to the pre-agreed structures defined in the XSD.

In the default case for a Map<String, String>, the generated XSD will restrict the map element to contain multiple entry elements each of which must contain one xs:string key and one xs:string value. That's a pretty clear interface contract.

What you describe is that you want the xml map to contain elements whose name will be determined by the content of the map at runtime. Then the generated XSD can only specify that the map must contain a list of elements whose type is unknown at compile time. This is something that you should generally avoid when defining an interface contract.

To achieve a strict contract in this case, you should use an enumerated type as the key of the map instead of a String. E.g.

public enum KeyType {
 KEY, KEY2;
}

@XmlJavaTypeAdapter(MapAdapter.class)
Map<KeyType , String> mapProperty;

That way the keys which you want to become elements in XML are known at compile time so JAXB should be able to generate a schema that would restrict the elements of map to elements using one of the predefined keys KEY or KEY2.

On the other hand, if you wish to simplify the default generated structure

<map>
    <entry>
        <key>KEY</key>
        <value>VALUE</value>
    </entry>
    <entry>
        <key>KEY2</key>
        <value>VALUE2</value>
    </entry>
</map>

To something simpler like this

<map>
    <item key="KEY" value="VALUE"/>
    <item key="KEY2" value="VALUE2"/>
</map>

You can use a MapAdapter that converts the Map to an array of MapElements as follows:

class MapElements {
    @XmlAttribute
    public String key;
    @XmlAttribute
    public String value;

    private MapElements() {
    } //Required by JAXB

    public MapElements(String key, String value) {
        this.key = key;
        this.value = value;
    }
}


public class MapAdapter extends XmlAdapter<MapElements[], Map<String, String>> {
    public MapAdapter() {
    }

    public MapElements[] marshal(Map<String, String> arg0) throws Exception {
        MapElements[] mapElements = new MapElements[arg0.size()];
        int i = 0;
        for (Map.Entry<String, String> entry : arg0.entrySet())
            mapElements[i++] = new MapElements(entry.getKey(), entry.getValue());

        return mapElements;
    }

    public Map<String, String> unmarshal(MapElements[] arg0) throws Exception {
        Map<String, String> r = new TreeMap<String, String>();
        for (MapElements mapelement : arg0)
            r.put(mapelement.key, mapelement.value);
        return r;
    }
}

The first one is invalid syntax. You cannot have object properties inside a plain array. The second one is right although it is not strict JSON. It's a relaxed form of JSON wherein quotes in string keys are omitted.

This tutorial by Patrick Hunlock, may help to learn about JSON and this site may help to validate JSON.

just added this to my class

@XmlAccessorType(XmlAccessType.FIELD)

worked like a cham

This is fixed in version 1.6 of the plugin.

            <groupId>org.codehaus.mojo</groupId>
            <artifactId>jaxb2-maven-plugin</artifactId>
            <version>1.6</version>

Quick note though, I noticed that the first iteration output was being deleted. I fixed it by adding the following to each of the executions.

                        <removeOldOutput>false</removeOldOutput>
                        <clearOutputDir>false</clearOutputDir>

Here is my full working example with each iteration outputting correctly. BTW I had to do this due to a duplicate namespace problem with the xsd's I was given. This seems to resolve my problem.

Why not use an external binding file to tell XJC to generate java.util.Date fields instead of XMLGregorianCalendar?

Also see How do I map xs:date to java.util.Date? Blog

In addition to all the answers, if you happen to receive in response text/html while you've expected something else (i.e. application/json), it may suggest that an error occurred on the server side (say 404) and the error page was returned instead of your data.

So it happened in my case. Hope it will save somebody's time.

As A4L mentioning, you can use StringWriter. Providing here example code:

private static String jaxbObjectToXML(Customer customer) {
    String xmlString = "";
    try {
        JAXBContext context = JAXBContext.newInstance(Customer.class);
        Marshaller m = context.createMarshaller();

        m.setProperty(Marshaller.JAXB_FORMATTED_OUTPUT, Boolean.TRUE); // To format XML

        StringWriter sw = new StringWriter();
        m.marshal(customer, sw);
        xmlString = sw.toString();

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

    return xmlString;
}

The correct scheme should be:

<?xml version="1.0" encoding="UTF-8"?>
<schema xmlns="http://www.w3.org/2001/XMLSchema" 
targetNamespace="http://www.example.org/Sport"
xmlns:tns="http://www.example.org/Sport" 
elementFormDefault="qualified"
xmlns:jaxb="http://java.sun.com/xml/ns/jaxb" 
jaxb:version="2.0">

<complexType name="sportType">
    <simpleContent>
        <extension base="string">
            <attribute name="type" type="string" />
            <attribute name="gender" type="string" />
        </extension>
    </simpleContent>
</complexType>

<element name="sports">
    <complexType>
        <sequence>
            <element name="sport" minOccurs="0" maxOccurs="unbounded"
                type="tns:sportType" />
        </sequence>
    </complexType>
</element>

Code generated for SportType will be:

package org.example.sport;

import javax.xml.bind.annotation.XmlAccessType;
import javax.xml.bind.annotation.XmlAccessorType;
import javax.xml.bind.annotation.XmlAttribute;
import javax.xml.bind.annotation.XmlType;


@XmlAccessorType(XmlAccessType.FIELD)
@XmlType(name = "sportType")
public class SportType {
    @XmlValue
    protected String value;
    @XmlAttribute
    protected String type;
    @XmlAttribute
    protected String gender;

    public String getValue() {
        return value;
    }

    public void setValue(String value) {
        this.value = value;
    }

    public String getType() {
    return type;
    }


    public void setType(String value) {
        this.type = value;
    }

    public String getGender() {
        return gender;

    public void setGender(String value) {
        this.gender = value;
    }
}

Old answer "Problem resolved by switching to amazoncorretto" News answer: I used corretto latest , but is similar jdk 1.8. so anyway we need add dependencies manually

All below options worked for me.

Option 1: Annotation for FIELD at class & field level with getter/setter methods

 @XmlRootElement(name = "fields")
 @XmlAccessorType(XmlAccessType.FIELD)
    public class Fields {

        @XmlElement(name = "field")
        List<Field> fields = new ArrayList<Field>();
            //getter, setter
    }

Option 2: No Annotation for FIELD at class level(@XmlAccessorType(XmlAccessType.FIELD) and with only getter method. Adding Setter method will throw the error as we are not including the Annotation in this case. Remember, setter is not required when you explicitly set the values in your XML file.

@XmlRootElement(name = "fields")
    public class Fields {

        @XmlElement(name = "field")
        List<Field> fields = new ArrayList<Field>();
            //getter
    }

Option 3: Annotation at getter method alone. Remember we can also use the setter method here as we are not doing any FIELD level annotation in this case.

@XmlRootElement(name = "fields")
    public class Fields {

        List<Field> fields = new ArrayList<Field>();

        @XmlElement(name = "field")
        //getter

        //setter
    }

Hope this helps you!

I believe you must add the namespace to your xml document, with, for example, the use of a SAX filter.

That means:

• Define a ContentHandler interface with a new class which will intercept SAX events before JAXB can get them.
• Define a XMLReader which will set the content handler

then link the two together:

public static Object unmarshallWithFilter(Unmarshaller unmarshaller,
java.io.File source) throws FileNotFoundException, JAXBException 
{
    FileReader fr = null;
    try {
        fr = new FileReader(source);
        XMLReader reader = new NamespaceFilterXMLReader();
        InputSource is = new InputSource(fr);
        SAXSource ss = new SAXSource(reader, is);
        return unmarshaller.unmarshal(ss);
    } catch (SAXException e) {
        //not technically a jaxb exception, but close enough
        throw new JAXBException(e);
    } catch (ParserConfigurationException e) {
        //not technically a jaxb exception, but close enough
        throw new JAXBException(e);
    } finally {
        FileUtil.close(fr); //replace with this some safe close method you have
    }
}

When you generate a JAXB model from an XML Schema, global elements that correspond to named complex types will have that metadata captured as an @XmlElementDecl annotation on a create method in the ObjectFactory class. Since you are creating the JAXBContext on just the DocumentType class this metadata isn't being processed. If you generated your JAXB model from an XML Schema then you should create the JAXBContext on the generated package name or ObjectFactory class to ensure all the necessary metadata is processed.

Example solution:

JAXBContext jaxbContext = JAXBContext.newInstance(my.generatedschema.dir.ObjectFactory.class);
DocumentType documentType = ((JAXBElement<DocumentType>) jaxbContext.createUnmarshaller().unmarshal(inputStream)).getValue();

Tests

On the Tests class we will add an @XmlRootElement annotation. Doing this will let your JAXB implementation know that when a document starts with this element that it should instantiate this class. JAXB is configuration by exception, this means you only need to add annotations where your mapping differs from the default. Since the testData property differs from the default mapping we will use the @XmlElement annotation. You may find the following tutorial helpful: http://wiki.eclipse.org/EclipseLink/Examples/MOXy/GettingStarted

package forum11221136;

import javax.xml.bind.annotation.*;

@XmlRootElement
public class Tests {

    TestData testData;

    @XmlElement(name="test-data")
    public TestData getTestData() {
        return testData;
    }

    public void setTestData(TestData testData) {
        this.testData = testData;
    }

}

TestData

On this class I used the @XmlType annotation to specify the order in which the elements should be ordered in. I added a testData property that appeared to be missing. I also used an @XmlElement annotation for the same reason as in the Tests class.

package forum11221136;

import java.util.List;
import javax.xml.bind.annotation.*;

@XmlType(propOrder={"title", "book", "count", "testData"})
public class TestData {
    String title;
    String book;
    String count;
    List<TestData> testData;

    public String getTitle() {
        return title;
    }
    public void setTitle(String title) {
        this.title = title;
    }
    public String getBook() {
        return book;
    }
    public void setBook(String book) {
        this.book = book;
    }
    public String getCount() {
        return count;
    }
    public void setCount(String count) {
        this.count = count;
    }
    @XmlElement(name="test-data")
    public List<TestData> getTestData() {
        return testData;
    }
    public void setTestData(List<TestData> testData) {
        this.testData = testData;
    }
}

Demo

Below is an example of how to use the JAXB APIs to read (unmarshal) the XML and populate your domain model and then write (marshal) the result back to XML.

package forum11221136;

import java.io.File;
import javax.xml.bind.*;

public class Demo {

    public static void main(String[] args) throws Exception {
        JAXBContext jc = JAXBContext.newInstance(Tests.class);

        Unmarshaller unmarshaller = jc.createUnmarshaller();
        File xml = new File("src/forum11221136/input.xml");
        Tests tests = (Tests) unmarshaller.unmarshal(xml);

        Marshaller marshaller = jc.createMarshaller();
        marshaller.setProperty(Marshaller.JAXB_FORMATTED_OUTPUT, true);
        marshaller.marshal(tests, System.out);
    }

}

marshaller.setProperty only works on the JAX-B marshaller from Sun. The question was regarding the JAX-B marshaller from SpringSource, which does not support setProperty.

None of the solutions mentioned here worked for me, I was still getting:

Exception in thread "main" javax.xml.bind.UnmarshalException: unexpected element (uri:"java:XXX.XX.XX.XXX", local:"XXXXX")

After lot of research through other sites below code worked for me-

FileInputStream fis = new FileInputStream("D:/group.xml");
SOAPMessage message = factory.createMessage(new MimeHeaders(), fis);
JAXBContext jc = JAXBContext.newInstance(Group.class);
Unmarshaller u = jc.createUnmarshaller();
JAXBElement<Group> r = u.unmarshal(message.getSOAPBody().extractContentAsDocument(), Group.class);
Group group = r.getValue();

You can fix this issue using the binding from How to generate @XmlRootElement Classes for Base Types in XSD?.

Here is an example with Maven

        <plugin>
            <groupId>org.codehaus.mojo</groupId>

                <extension>true</extension>
            </configuration>
        </plugin>

Here is the binding.xjb file content

<?xml version="1.0"?>

This ERROR can happen when you use Mockito to mock final classes.

Consider using Mockito inline or Powermock instead.

You can use: marshaller.setProperty("jaxb.fragment", Boolean.TRUE);

It works for me on Java 8

From a personal blog post, it is not necessary to create a specific JaxbList < T > object.

Assuming an object with a list of strings:

@XmlRootElement
public class ObjectWithList {

    private List<String> list;

    @XmlElementWrapper(name="MyList")
    @XmlElement
    public List<String> getList() {
        return list;
    }

    public void setList(List<String> list) {
        this.list = list;
    }

}

A JAXB round trip:

public static void simpleExample() throws JAXBException {

    List<String> l = new ArrayList<String>();
    l.add("Somewhere");
    l.add("This and that");
    l.add("Something");

    // Object with list
    ObjectWithList owl = new ObjectWithList();
    owl.setList(l);

    JAXBContext jc = JAXBContext.newInstance(ObjectWithList.class);
    ObjectWithList retr = marshallUnmarshall(owl, jc);

    for (String s : retr.getList()) {
        System.out.println(s);
    } System.out.println(" ");

}

Produces the following:

<?xml version="1.0" encoding="UTF-8" standalone="yes"?>
<objectWithList>
    <MyList>
        <list>Somewhere</list>
        <list>This and that</list>
        <list>Something</list>
    </MyList>
</objectWithList>

Fixed it by setting the class name to the property "classesToBeBound" of the JAXB marshaller:

<bean id="jaxbMarshaller" class="org.springframework.oxm.jaxb.Jaxb2Marshaller">
        <property name="classesToBeBound">
          <list>
                <value>myclass</value>
          </list>
        </property>
</bean>

Other alternative:

JAXBElement<String> element = new JAXBElement<>(new QName("Your localPart"),
                                                String.class, "Your message");

Then:

System.out.println(element.getValue()); // Result: Your message

1. Download http://java.net/downloads/jaxb-workshop/IDE%20plugins/org.jvnet.jaxbw.zip
2. Extract the zip file .
3. Place the org.jvnet.jaxbw.eclipse_1.0.0 folder into .eclipse\plugins folder
4. Restart the eclipse.
5. Right click on XSD file and you can find contect menu. JAXB 2.0 -> Run XJC .

For me the issue was that I was calling onProgressUpdate() explicitly from my code. This shouldn't be done. I called publishProgress() instead and that resolved the error.

You can use Joshua's solution but I think you need Elts_int <- as.matrix(tmp_int)

Or for loops:

z <- 1 ## Initialize
counter <- 1 ## Initialize
for(y in 1:48) { ## Assuming 48 columns otherwise, swap 48 and 32
for (x in 1:32) {  
z[counter] <- tmp_int[x,y]
counter <- 1 + counter
}
}

z is a 1d vector.

If you want to add it directly in the toolbar.

If I just want to insert simple test data I often implement a ApplicationRunner. Implementations of this interface are run at application startup and can use e.g. a autowired repository to insert some test data.

I think such an implementation would be slightly more explicit than yours because the interface implies that your implementation contains something you would like to do directly after your application is ready.

Your implementation would look sth. like this:

@Component
public class DataLoader implements ApplicationRunner {

    private UserRepository userRepository;

    @Autowired
    public DataLoader(UserRepository userRepository) {
        this.userRepository = userRepository;
    }

    public void run(ApplicationArguments args) {
        userRepository.save(new User("lala", "lala", "lala"));
    }
}

That happened to me exactly the same with this:

<%@ page language="java" contentType="application/json" pageEncoding="UTF-8"%>

But this works for me:

<%@ page language="java" contentType="application/json; charset=UTF-8" pageEncoding="UTF-8"%>

Try adding

 ;charset=UTF-8

to your contentType.

svn update /path/to/working/copy

If subversion is not in your PATH, then of course

/path/to/subversion/svn update /path/to/working/copy

or if you are in the current root directory of your svn repo (it contains a .svn subfolder), it's as simple as

svn update

For any Single File Component users, here is how I set up global variable(s)

1. Assuming you are using Vue-Cli's webpack template

2. Declare your variable(s) in somewhere variable.js

   const shallWeUseVuex = false;
   

3. Export it in variable.js

   module.exports = { shallWeUseVuex : shallWeUseVuex };
   

4. Require and assign it in your vue file

   export default {
       data() {
           return {
               shallWeUseVuex: require('../../variable.js')
           };
       }
   }

You can find the last column of table and then fill the cell by looping throught it.

Sub test()
    Dim lastCol As Long, i As Integer
    lastCol = Range("AZ1").End(xlToLeft).Column
        For i = 1 To lastCol
            Cells(1, i).Value = "PHEV"
        Next
End Sub

Provide the data frame and a string of comma separated names to remove:

remove_features <- function(df, features) {
  rem_vec <- unlist(strsplit(features, ', '))
  res <- df[,!(names(df) %in% rem_vec)]
  return(res)
}

Usage:

remove_features(iris, "Sepal.Length, Petal.Width")

By the looks of it you need to actually pass drawImage an image object like so

var image = new Image();_x000D_
image.onload = function() {_x000D_
  ctx.drawImage(image, 0, 0);_x000D_

I am a late comer, but maybe I can say this with a specific example:

Say, if you have a <table>, with <tr>, and then <td>. Now, let's say you set 3 event handlers for the <td> element, then if you do event.stopPropagation() in the first event handler you set for <td>, then all event handlers for <td> will still run, but the event just won't propagate to <tr> or <table> (and won't go up and up to <body>, <html>, document, and window).

Now, however, if you use event.stopImmediatePropagation() in your first event handler, then, the other two event handlers for <td> WILL NOT run, and won't propagate up to <tr>, <table> (and won't go up and up to <body>, <html>, document, and window).

Note that it is not just for <td>. For other elements, it will follow the same principle.

If you use tostring you lose information on both shape and data type:

>>> import numpy as np
>>> a = np.arange(12).reshape(3, 4)
>>> a
array([[ 0,  1,  2,  3],
       [ 4,  5,  6,  7],
       [ 8,  9, 10, 11]])
>>> s = a.tostring()
>>> aa = np.fromstring(a)
>>> aa
array([  0.00000000e+000,   4.94065646e-324,   9.88131292e-324,
         1.48219694e-323,   1.97626258e-323,   2.47032823e-323,
         2.96439388e-323,   3.45845952e-323,   3.95252517e-323,
         4.44659081e-323,   4.94065646e-323,   5.43472210e-323])
>>> aa = np.fromstring(a, dtype=int)
>>> aa
array([ 0,  1,  2,  3,  4,  5,  6,  7,  8,  9, 10, 11])
>>> aa = np.fromstring(a, dtype=int).reshape(3, 4)
>>> aa
array([[ 0,  1,  2,  3],
       [ 4,  5,  6,  7],
       [ 8,  9, 10, 11]])

This means you have to send the metadata along with the data to the recipient. To exchange auto-consistent objects, try cPickle:

>>> import cPickle
>>> s = cPickle.dumps(a)
>>> cPickle.loads(s)
array([[ 0,  1,  2,  3],
       [ 4,  5,  6,  7],
       [ 8,  9, 10, 11]])

Yes, use the rendered attribute.

<h:form rendered="#{some boolean condition}">

You usually tie it to the model rather than letting the model grab the component and manipulate it.

E.g.

<h:form rendered="#{bean.booleanValue}" />
<h:form rendered="#{bean.intValue gt 10}" />
<h:form rendered="#{bean.objectValue eq null}" />
<h:form rendered="#{bean.stringValue ne 'someValue'}" />
<h:form rendered="#{not empty bean.collectionValue}" />
<h:form rendered="#{not bean.booleanValue and bean.intValue ne 0}" />
<h:form rendered="#{bean.enumValue eq 'ONE' or bean.enumValue eq 'TWO'}" />

Note the importance of keyword based EL operators such as gt, ge, le and lt instead of >, >=, <= and < as angle brackets < and > are reserved characters in XML. See also this related Q&A: Error parsing XHTML: The content of elements must consist of well-formed character data or markup.

As to your specific use case, let's assume that the link is passing a parameter like below:

<a href="page.xhtml?form=1">link</a>

You can then show the form as below:

<h:form rendered="#{param.form eq '1'}">

(the #{param} is an implicit EL object referring to a Map representing the request parameters)

I would use reduce

var myData = new Array(['2013-01-22', 0], ['2013-01-29', 0], ['2013-02-05', 0], ['2013-02-12', 0], ['2013-02-19', 0], ['2013-02-26', 0], ['2013-03-05', 0], ['2013-03-12', 0], ['2013-03-19', 0], ['2013-03-26', 0], ['2013-04-02', 21], ['2013-04-09', 2]);

var sum = myData.reduce(function(a, b) {
    return a + b[1];
}, 0);

$("#result").text(sum);

You just need to use single quotes:

$ echo "$TEST"
test
$ echo '$TEST'
$TEST

Inside single quotes special characters are not special any more, they are just normal characters.

One very simple way to make a method asynchronous is to use Task.Yield() method. As MSDN states:

You can use await Task.Yield(); in an asynchronous method to force the method to complete asynchronously.

Insert it at beginning of your method and it will then return immediately to the caller and complete the rest of the method on another thread.

private async Task<DateTime> CountToAsync(int num = 1000)
{
    await Task.Yield();
    for (int i = 0; i < num; i++)
    {
        Console.WriteLine("#{0}", i);
    }
    return DateTime.Now;
}

You can simply print it.

@a = qw(abc def hij);

print "@a";

You will got:

abc def hij

For ease of re-use throughout your application a static class may help.

public static class StaticRandom
{
    private static int seed;

    private static ThreadLocal<Random> threadLocal = new ThreadLocal<Random>
        (() => new Random(Interlocked.Increment(ref seed)));

    static StaticRandom()
    {
        seed = Environment.TickCount;
    }

    public static Random Instance { get { return threadLocal.Value; } }
}

You can use then use static random instance with code such as

StaticRandom.Instance.Next(1, 100);

How about CryptoJS?

It's a solid crypto library, with a lot of functionality. It implements hashers, HMAC, PBKDF2 and ciphers. In this case ciphers is what you need. Check out the quick-start quide on the project's homepage.

You could do something like with the AES:

<script src="http://crypto-js.googlecode.com/svn/tags/3.1.2/build/rollups/aes.js"></script>

<script>
    var encryptedAES = CryptoJS.AES.encrypt("Message", "My Secret Passphrase");
    var decryptedBytes = CryptoJS.AES.decrypt(encryptedAES, "My Secret Passphrase");
    var plaintext = decryptedBytes.toString(CryptoJS.enc.Utf8);
</script>

As for security, at the moment of my writing AES algorithm is thought to be unbroken

Edit :

Seems online URL is down & you can use the downloaded files for encryption from below given link & place the respective files in your root folder of the application.

https://code.google.com/archive/p/crypto-js/downloads

or used other CDN like https://cdnjs.cloudflare.com/ajax/libs/crypto-js/3.1.2/components/aes-min.js

Here is the simplest solution using javascript string functions.

document.cookie.substring(document.cookie.indexOf("COOKIE_NAME"), 
                          document.cookie.indexOf(";", 
                          document.cookie.indexOf("COOKIE_NAME"))).
  substr(COOKIE_NAME.length);

tl;dr

Start-Process powershell { sleep 30 }

I do below and check if id exist and execute function if exist.

var divIDVar = $('#divID').length;
if (divIDVar === 0){ 
    console.log('No DIV Exist'); 
} else{  
    FNCsomefunction(); 
}   

I get the same error in Cygwin. I had to install the openssh package in Cygwin Setup.

(The strange thing was that all ssh-* commands were valid, (bash could execute as program) but the openssh package wasn't installed.)

You should use LOAD_FILE like so:

LOAD_FILE('/some/path/image.png')

To further generalize @Alexander's example, outer is relevant in cases where a function must compute itself on each pair of vector values:

vars1<-c(1,2,3)
vars2<-c(10,20,30)
mult_one<-function(var1,var2)
{
   var1*var2
}
outer(vars1,vars2,mult_one)

gives:

> outer(vars1, vars2, mult_one)
     [,1] [,2] [,3]
[1,]   10   20   30
[2,]   20   40   60
[3,]   30   60   90

It declares a type based on what is assigned to it in the initialisation.

A simple example is that the code:

var i = 53;

Will examine the type of 53, and essentially rewrite this as:

int i = 53;

Note that while we can have:

long i = 53;

This won't happen with var. Though it can with:

var i = 53l; // i is now a long

Similarly:

var i = null; // not allowed as type can't be inferred.
var j = (string) null; // allowed as the expression (string) null has both type and value.

This can be a minor convenience with complicated types. It is more important with anonymous types:

var i = from x in SomeSource where x.Name.Length > 3 select new {x.ID, x.Name};
foreach(var j in i)
  Console.WriteLine(j.ID.ToString() + ":" + j.Name);

Here there is no other way of defining i and j than using var as there is no name for the types that they hold.

AskTom is probably the single most helpful resource on best practices on Oracle DBs. (I usually just type "asktom" as the first word of a google query on a particular topic)

I don't think it's really appropriate to speak of design patterns with relational databases. Relational databases are already the application of a "design pattern" to a problem (the problem being "how to represent, store and work with data while maintaining its integrity", and the design being the relational model). Other approches (generally considered obsolete) are the Navigational and Hierarchical models (and I'm nure many others exist).

Having said that, you might consider "Data Warehousing" as a somewhat separate "pattern" or approach in database design. In particular, you might be interested in reading about the Star schema.

Simple ASP.NET MVC subscription form with email textbox would be implemented like that:

Model

The data from the form is mapped to this model

public class SubscribeModel
{
    [Required]
    public string Email { get; set; }
}

View

View name should match controller method name.

@model App.Models.SubscribeModel

@using (Html.BeginForm("Subscribe", "Home", FormMethod.Post))
{
    @Html.TextBoxFor(model => model.Email)
    @Html.ValidationMessageFor(model => model.Email)
    <button type="submit">Subscribe</button>
}

Controller

Controller is responsible for request processing and returning proper response view.

public class HomeController : Controller
{
    public ActionResult Index()
    {
        return View();
    }

    [HttpPost]
    public ActionResult Subscribe(SubscribeModel model)
    {
        if (ModelState.IsValid)
        {
            //TODO: SubscribeUser(model.Email);
        }

        return View("Index", model);
    }
}

Here is my project structure. Please notice, "Home" views folder matches HomeController name.

you can convert a string to array with str_split and use foreach

$chars = str_split($str);
foreach($chars as $char){
    // your code
}

Use svcutil.exe with the /sc switch to generate the WCF contracts. This will create a code file that you can add to your project. It will contain all interfaces and data types you need to create your service. Change the output location using the /o switch, or you can find the file in the folder where you ran svcutil.exe. The default language is C# but I think (I've never tried it) you should be able to change this using /l:vb.

svcutil /sc "WSDL file path"

If your WSDL has any supporting XSD files pass those in as arguments after the WSDL.

svcutil /sc "WSDL file path" "XSD 1 file path" "XSD 2 file path" ... "XSD n file path"

Then create a new class that is your service and implement the contract interface you just created.

You can trigger a file input element by sending it a Javascript click event, e.g.

<input type="file" ... id="file-input">

$("#file-input").click();

You could put this in a click event handler for the image, for instance, then hide the file input with CSS. It'll still work even if it's invisible.

Once you've got that part working, you can set a change event handler on the input element to see when the user puts a file into it. This event handler can create a temporary "blob" URL for the image by using window.URL.createObjectURL, e.g.:

var file = document.getElementById("file-input").files[0];
var blob_url = window.URL.createObjectURL(file);

That URL can be set as the src for an image on the page. (It only works on that page, though. Don't try to save it anywhere.)

Note that not all browsers currently support camera capture. (In fact, most desktop browsers don't.) Make sure your interface still makes sense if the user gets asked to pick a file.

Your syntax is incorrect. You can't use ELSE IF. It appears that you don't really need it anyway. Simply use multiple IF statements:

IF %F%==1 IF %C%==1 (
    ::copying the file c to d
    copy "%sourceFile%" "%destinationFile%"
    )

IF %F%==1 IF %C%==0 (
    ::moving the file c to d
    move "%sourceFile%" "%destinationFile%"
    )

IF %F%==0 IF %C%==1 (
    ::copying a directory c from d, /s:  bos olanlar hariç, /e:bos olanlar dahil
    xcopy "%sourceCopyDirectory%" "%destinationCopyDirectory%" /s/e
    )

IF %F%==0 IF %C%==0 (
    ::moving a directory
    xcopy /E "%sourceMoveDirectory%" "%destinationMoveDirectory%"
    rd /s /q "%sourceMoveDirectory%"
    )

The following is of course all not quite precise. Take it with a grain of salt when you read it :)

Well, the three things you refer to are automatic, static and dynamic storage duration, which has something to do with how long objects live and when they begin life.

Automatic storage duration

You use automatic storage duration for short lived and small data, that is needed only locally within some block:

if(some condition) {
    int a[3]; // array a has automatic storage duration
    fill_it(a);
    print_it(a);
}

The lifetime ends as soon as we exit the block, and it starts as soon as the object is defined. They are the most simple kind of storage duration, and are way faster than in particular dynamic storage duration.

Static storage duration

You use static storage duration for free variables, which might be accessed by any code all times, if their scope allows such usage (namespace scope), and for local variables that need extend their lifetime across exit of their scope (local scope), and for member variables that need to be shared by all objects of their class (classs scope). Their lifetime depends on the scope they are in. They can have namespace scope and local scope and class scope. What is true about both of them is, once their life begins, lifetime ends at the end of the program. Here are two examples:

// static storage duration. in global namespace scope
string globalA; 
int main() {
    foo();
    foo();
}

void foo() {
    // static storage duration. in local scope
    static string localA;
    localA += "ab"
    cout << localA;
}

The program prints ababab, because localA is not destroyed upon exit of its block. You can say that objects that have local scope begin lifetime when control reaches their definition. For localA, it happens when the function's body is entered. For objects in namespace scope, lifetime begins at program startup. The same is true for static objects of class scope:

class A {
    static string classScopeA;
};

string A::classScopeA;

A a, b; &a.classScopeA == &b.classScopeA == &A::classScopeA;

As you see, classScopeA is not bound to particular objects of its class, but to the class itself. The address of all three names above is the same, and all denote the same object. There are special rule about when and how static objects are initialized, but let's not concern about that now. That's meant by the term static initialization order fiasco.

Dynamic storage duration

The last storage duration is dynamic. You use it if you want to have objects live on another isle, and you want to put pointers around that reference them. You also use them if your objects are big, and if you want to create arrays of size only known at runtime. Because of this flexibility, objects having dynamic storage duration are complicated and slow to manage. Objects having that dynamic duration begin lifetime when an appropriate new operator invocation happens:

int main() {
    // the object that s points to has dynamic storage 
    // duration
    string *s = new string;
    // pass a pointer pointing to the object around. 
    // the object itself isn't touched
    foo(s);
    delete s;
}

void foo(string *s) {
    cout << s->size();
}

Its lifetime ends only when you call delete for them. If you forget that, those objects never end lifetime. And class objects that define a user declared constructor won't have their destructors called. Objects having dynamic storage duration requires manual handling of their lifetime and associated memory resource. Libraries exist to ease use of them. Explicit garbage collection for particular objects can be established by using a smart pointer:

int main() {
    shared_ptr<string> s(new string);
    foo(s);
}

void foo(shared_ptr<string> s) {
    cout << s->size();
}

You don't have to care about calling delete: The shared ptr does it for you, if the last pointer that references the object goes out of scope. The shared ptr itself has automatic storage duration. So its lifetime is automatically managed, allowing it to check whether it should delete the pointed to dynamic object in its destructor. For shared_ptr reference, see boost documents: http://www.boost.org/doc/libs/1_37_0/libs/smart_ptr/shared_ptr.htm

I have stopped using ORMs.

The reason is not any great flaw in the concept. Hibernate works well. Instead, I have found that queries have low overhead and I can fit lots of complex logic into large SQL queries, and shift a lot of my processing into the database.

So consider just using the JDBC package.

To match either / or end of content, use (/|\z)

This only applies if you are not using multi-line matching (i.e. you're matching a single URL, not a newline-delimited list of URLs).

To put that with an updated version of what you had:

/(\S+?)/(\d{4}-\d{2}-\d{2})-(\d+)(/|\z)

Note that I've changed the start to be a non-greedy match for non-whitespace ( \S+? ) rather than matching anything and everything ( .* )

Don't use spaces...

    local trimmed="$1"

    # Strip leading space.
    trimmed="${trimmed## }"
    # Strip trailing space.
    trimmed="${trimmed%% }"

For example:

test1="$(trim " one leading")"
test2="$(trim "one trailing ")"
test3="$(trim " one leading and one trailing ")"
echo "'$test1', '$test2', '$test3'"

Output:

'one leading', 'one trailing', 'one leading and one trailing'

        trimmed="${trimmed%% }"
    done

    echo "$trimmed"
}

For example:

test4="$(trim "  two leading")"
test5="$(trim "two trailing  ")"
test6="$(trim "  two leading and two trailing  ")"
echo "'$test4', '$test5', '$test6'"

Output:

'two leading', 'two trailing', 'two leading and two trailing'

In my case, I had the whole variable for JAVA_HOME in quotes. I just had to remove the quotes and then it worked fine.

Try this from your shell:

$ od -A n -t d -N 1 /dev/urandom

Here, -t d specifies that the output format should be signed decimal; -N 1 says to read one byte from /dev/urandom.

If "website" can be empty than new_field should also be set to be empty.

Now if you want to add logic on save where if new_field is empty to grab the value from "website" all you need to do is override the save function for your Model like this:

class UserProfile(models.Model):
    user = models.OneToOneField(User)
    website = models.URLField(blank=True, default='DEFAULT VALUE')
    new_field = models.CharField(max_length=140, blank=True, default='DEFAULT VALUE')

    def save(self, *args, **kwargs):
        if not self.new_field:
            # Setting the value of new_field with website's value
            self.new_field = self.website

        # Saving the object with the default save() function
        super(UserProfile, self).save(*args, **kwargs)

Try position:fixed; bottom:0;. This will make your div to stay fixed at the bottom.

WORKING DEMO

The HTML:

<div id="bottom-stuff">
  <div id="search"> MY DIV </div>
</div>
<div id="bottom"> MY DIV </div>

The CSS:

#bottom-stuff {

    position: relative;
}

#bottom{

    position: fixed; 
    background:gray; 
    width:100%;
    bottom:0;
}

#search{height:5000px; overflow-y:scroll;}

Hope this helps.

Read line by line, not the whole file:

for line in open(file_name, 'rb'):
    # process line here

Even better use with for automatically closing the file:

with open(file_name, 'rb') as f:
    for line in f:
        # process line here

The above will read the file object using an iterator, one line at a time.

Shift + Alt + J will help you add author name in existing file.

To add author name automatically,
go to Preferences --> java --> Code Style --> Code Templates

in case you don't find above option in new versions of Eclipse - install it from https://marketplace.eclipse.org/content/jautodoc

This can be done by splitting the string a couple of times.

#Path
$Link = "http://some.url/some/path/file.name"

#Split path on "/"
#Results of split will look like this : 
# http:
#
# some.url
# some
# path
# file.name
$Split = $Link.Split("/")

#Count how many Split strings there are
#There are 6 strings that have been split in my example
$SplitCount = $Split.Count

#Select the last string
#Result of this selection : 
# file.name
$FilenameWithExtension = $Split[$SplitCount -1]

#Split filename on "."
#Result of this split : 
# file
# name
$FilenameWithExtensionSplit = $FilenameWithExtension.Split(".")

#Select the first half
#Result of this selection : 
# file
$FilenameWithoutExtension = $FilenameWithExtensionSplit[0]

#The filename without extension is in this variable now
# file
$FilenameWithoutExtension

Here is the code without comments :

$Link = "http://some.url/some/path/file.name"
$Split = $Link.Split("/")
$SplitCount = $Split.Count
$FilenameWithExtension = $Split[$SplitCount -1]
$FilenameWithExtensionSplit = $FilenameWithExtension.Split(".")
$FilenameWithoutExtension = $FilenameWithExtensionSplit[0]
$FilenameWithoutExtension

Most databases will accept this:

select * from SomeTable where true

However some databases (eg SQL Server, Oracle) do not have a boolean type. In these cases you may use:

select * from SomeTable where 1=1

BTW, if building up an sql where clause by hand, this is the basis for simplifying your code because you can avoid having to know if the condition you're about to add to a where clause is the first one (which should be preceded by "WHERE"), or a subsequent one (which should be preceded by "AND"). By always starting with "WHERE 1=1", all conditions (if any) added to the where clause are preceded by "AND".

What I believe you're looking for is a way to work with arrays as object values:

var o = {} // empty Object
var key = 'Orientation Sensor';
o[key] = []; // empty Array, which you can push() values into


var data = {
    sampleTime: '1450632410296',
    data: '76.36731:3.4651554:0.5665419'
};
var data2 = {
    sampleTime: '1450632410296',
    data: '78.15431:0.5247617:-0.20050584'
};
o[key].push(data);
o[key].push(data2);

This is standard JavaScript and not something NodeJS specific. In order to serialize it to a JSON string you can use the native JSON.stringify:

JSON.stringify(o);
//> '{"Orientation Sensor":[{"sampleTime":"1450632410296","data":"76.36731:3.4651554:0.5665419"},{"sampleTime":"1450632410296","data":"78.15431:0.5247617:-0.20050584"}]}'

Yeah it's possible.

Button myBtn = (Button)findViewById(R.id.myButtonId);
myBtn.requestFocus();

or in XML

<Button ...><requestFocus /></Button>

Important Note: The button widget needs to be focusable and focusableInTouchMode. Most widgets are focusable but not focusableInTouchMode by default. So make sure to either set it in code

myBtn.setFocusableInTouchMode(true);

or in XML

android:focusableInTouchMode="true"

SELECT DISTINCT (t1.ProdId), t1.Quantity FROM Dummy t1 INNER JOIN
       (SELECT ProdId, MAX(Quantity) as MaxQuantity FROM Dummy GROUP BY ProdId) t2
    ON t1.ProdId = t2.ProdId
   AND t1.Quantity = t2.MaxQuantity
 ORDER BY t1.ProdId

this will give you the idea.

In python, bool(sequence) is False if the sequence is empty. Since strings are sequences, this will work:

cookie = ''
if cookie:
    print "Don't see this"
else:
    print "You'll see this"

The easiest way to debug python - especially for programmers that are used to Visual Studio - is using PTVS (Python Tools for Visual Studio). The steps are simple:

1. Download and install it from http://pytools.codeplex.com/
2. Set breakpoints and press F5.
3. Your breakpoint is hit, you can view/change the variables as easy as debugging C#/C++ programs.
4. That's all :)

If you want to debug Django using PTVS, you need to do the following:

1. In Project settings - General tab, set "Startup File" to "manage.py", the entry point of the Django program.
2. In Project settings - Debug tab, set "Script Arguments" to "runserver --noreload". The key point is the "--noreload" here. If you don't set it, your breakpoints won't be hit.
3. Enjoy it.

There are pre-release (beta) versions of NCover available for free. They work fine for most cases, especially when combined with NCoverExplorer.

It heavily depends on the environment you're working in. Take for example javascript. In javascript the best way to pass in parameters is using objects with key/value pairs, which in practice means you only have one parameter. In other systems the sweet spot will be at three or four.

In the end, it all boils down to personal taste.

You can query the table msdb.dbo.sysjobactivity to determine if the job is currently running.

   .search-table-outter {border:2px solid red; overflow-x:scroll;}
   .search-table{table-layout: fixed; margin:40px auto 0px auto;   }
   .search-table, td, th{border-collapse:collapse; border:1px solid #777;}
   th{padding:20px 7px; font-size:15px; color:#444; background:#66C2E0;}
   td{padding:5px 10px; height:35px;}

You should provide scroll in div.

Shellwrap is great tool for using the command-line in PHP!

Your example can be done quite easy and readable:

use MrRio\ShellWrap as sh;

$xml = (string)sh::curl(['u' => 'user:pass'], 'http://example.com/file.xml');

Since you are copying tha same data to all rows, you don't actually need to loop at all. Try this:

Sub ARRAYER()
    Dim Number_of_Sims As Long
    Dim rng As Range

    Application.Calculation = xlCalculationManual
    Application.ScreenUpdating = False
    Number_of_Sims = 100000

    Set rng = Range("C4:G4")
    rng.Offset(1, 0).Resize(Number_of_Sims) = rng.Value

    Application.Calculation = xlCalculationAutomatic
    Application.ScreenUpdating = True
End Sub

Generally speaking, using setState inside useEffect will create an infinite loop that most likely you don't want to cause. There are a couple of exceptions to that rule which I will get into later.

useEffect is called after each render and when setState is used inside of it, it will cause the component to re-render which will call useEffect and so on and so on.

One of the popular cases that using useState inside of useEffect will not cause an infinite loop is when you pass an empty array as a second argument to useEffect like useEffect(() => {....}, []) which means that the effect function should be called once: after the first mount/render only. This is used widely when you're doing data fetching in a component and you want to save the request data in the component's state.

So, say you have your View with PartialView, which have to be updated by button click:

<div class="target">
    @{ Html.RenderAction("UpdatePoints");}
</div>

<input class="button" value="update" />

There are some ways to do it. For example you may use jQuery:

<script type="text/javascript">
    $(function(){    
        $('.button').on("click", function(){        
            $.post('@Url.Action("PostActionToUpdatePoints", "Home")').always(function(){
                $('.target').load('/Home/UpdatePoints');        
            })        
        });
    });        
</script>

PostActionToUpdatePoints is your Action with [HttpPost] attribute, which you use to update points

If you use logic in your action UpdatePoints() to update points, maybe you forgot to add [HttpPost] attribute to it:

[HttpPost]
public ActionResult UpdatePoints()
{    
    ViewBag.points =  _Repository.Points;
    return PartialView("UpdatePoints");
}

Tried the below program , With both the approach. 1. With clearing the arraylist obj in for loop 2. creating new New Arraylist in for loop.

List al= new ArrayList();
        for(int i=0;i<100;i++)
        {
            //List al= new ArrayList();

            for(int j=0;j<10;j++)
            {
                al.add(Integer.parseInt("" +j+i));
                //System.out.println("Obj val " +al.get(j));
            }
            //System.out.println("Hashcode : " + al.hashCode());
            al.clear();

        }

and to my surprise. the memory allocation didnt change much.

With New Arraylist approach.

Before loop total free memory: 64,909 ::

After loop total free memory: 64,775 ::

with Clear approach,

Before loop total free memory: 64,909 :: After loop total free memory: 64,765 ::

So this says there is not much difference in using arraylist.clear from memory utilization perspective.

mystring = mystring.replace(/["']/g, "");

I think that you'll find interesting stuff in the following answer of mine that I did for a previous similar question:

https://stackoverflow.com/q/5929469/551449

In this answer, I proposed a pattern that allows a regex to catch any kind of number and since I have nothing else to add to it, I think it is fairly complete

This would be an optimized way of doing it

StringBuilder sb = new StringBuilder();
for (String n : arr) { 
    sb.append("'").append(n).append("',");
}
if(sb.length()>0)
    sb.setLength(sbDiscrep.length()-1);
return sb.toString();

Swift 4.2 Solution: For transparent Background:

1. For General Approach:

   override func viewDidLoad() {
       super.viewDidLoad()
   
       self.navigationController?.navigationBar.setBackgroundImage(UIImage(), for: UIBarMetrics.default)
       self.navigationController?.navigationBar.shadowImage = UIImage()
       self.navigationController?.navigationBar.isTranslucent = true
   
   }
   

2. For Specific Object:

   override func viewDidLoad() {
       super.viewDidLoad()
   
       navBar.setBackgroundImage(UIImage(), for: UIBarMetrics.default)
       navBar.shadowImage = UIImage()
       navBar.navigationBar.isTranslucent = true
   
   }
   

Hope it's useful.

The FOR loop worked well, I modified it a tiny bit:

#include<iostream>
using namespace std;
int main ()
{

    int sum = 0;
    int number;
    int numberitems;


    cout << "Enter number of items: \n";
    cin >> numberitems;

    for(int i=0;i<numberitems;i++)
    {
        cout << "Enter number: \n";
        cin >> number; 

        sum=sum+number;

    }
    cout<<"sum is: "<< sum<<endl;
}

HOWEVER, the WHILE loop has got some errors on line 11 (Count was not declared in this scope). What could be the issue? Also, if you would have a solution using DO,WHILE loop it would be wonderful. Thanks

Source (Py v2.7.3) for traceback.format_exception() and called/related functions helps greatly. Embarrassingly, I always forget to Read the Source. I only did so for this after searching for similar details in vain. A simple question, "How to recreate the same output as Python for an exception, with all the same details?" This would get anybody 90+% to whatever they're looking for. Frustrated, I came up with this example. I hope it helps others. (It sure helped me! ;-)

import sys, traceback

traceback_template = '''Traceback (most recent call last):
  File "%(filename)s", line %(lineno)s, in %(name)s
%(type)s: %(message)s\n''' # Skipping the "actual line" item

# Also note: we don't walk all the way through the frame stack in this example
# see hg.python.org/cpython/file/8dffb76faacc/Lib/traceback.py#l280
# (Imagine if the 1/0, below, were replaced by a call to test() which did 1/0.)

try:
    1/0
except:
    # http://docs.python.org/2/library/sys.html#sys.exc_info
    exc_type, exc_value, exc_traceback = sys.exc_info() # most recent (if any) by default

    '''
    Reason this _can_ be bad: If an (unhandled) exception happens AFTER this,
    or if we do not delete the labels on (not much) older versions of Py, the
    reference we created can linger.

    traceback.format_exc/print_exc do this very thing, BUT note this creates a
    temp scope within the function.
    '''

    traceback_details = {
                         'filename': exc_traceback.tb_frame.f_code.co_filename,
                         'lineno'  : exc_traceback.tb_lineno,
                         'name'    : exc_traceback.tb_frame.f_code.co_name,
                         'type'    : exc_type.__name__,
                         'message' : exc_value.message, # or see traceback._some_str()
                        }

    del(exc_type, exc_value, exc_traceback) # So we don't leave our local labels/objects dangling
    # This still isn't "completely safe", though!
    # "Best (recommended) practice: replace all exc_type, exc_value, exc_traceback
    # with sys.exc_info()[0], sys.exc_info()[1], sys.exc_info()[2]

    print
    print traceback.format_exc()
    print
    print traceback_template % traceback_details
    print

In specific answer to this query:

sys.exc_info()[0].__name__, os.path.basename(sys.exc_info()[2].tb_frame.f_code.co_filename), sys.exc_info()[2].tb_lineno

I was asking myself the same question few times. And even though the guys here tried hard to explain it, IMHO the best answer (and simplest) answer I have found is the description of the Class method in the Python Documentation.

There is also reference to the Static method. And in case someone already know instance methods (which I assume), this answer might be the final piece to put it all together...

Further and deeper elaboration on this topic can be found also in the documentation: The standard type hierarchy (scroll down to Instance methods section)

The following snippet should do the trick (and you can ignore most of the serialization attributes):

public class Car
{
  public string StockNumber { get; set; }
  public string Make { get; set; }
  public string Model { get; set; }
}

[XmlRootAttribute("Cars")]
public class CarCollection
{
  [XmlElement("Car")]
  public Car[] Cars { get; set; }
}

...

using (TextReader reader = new StreamReader(path))
{
  XmlSerializer serializer = new XmlSerializer(typeof(CarCollection));
  return (CarCollection) serializer.Deserialize(reader);
}

If anyone is strugling with the same problem I solved it by adding @EntityScan in my main class. Just add your model package to the basePackages property.

Try this:

foreach (string printer in System.Drawing.Printing.PrinterSettings.InstalledPrinters)
{
    MessageBox.Show(printer);
}

Try this below code

<?php
$file = 'dummy.pdf';
$filename = 'dummy.pdf';
header('Content-type: application/pdf');
header('Content-Disposition: inline; filename="' . $filename . '"');
header('Content-Transfer-Encoding: binary');
header('Content-Length: ' . filesize($file));
header('Accept-Ranges: bytes');
@readfile($file);
?>

This was a Tomcat bug that resurfaced again with the Java 9 bytecode. The exact versions which fix this (for both Java 8/9 bytecode) are:

• trunk for 9.0.0.M18 onwards

• 8.0.x for 8.0.42 onwards
• 7.0.x for 7.0.76 onwards

If you can't use the delay method as Robert Harvey suggested, you can use setTimeout.

Eg.

setTimeout(function() {$("#test").animate({"top":"-=80px"})} , 1500); // delays 1.5 sec
setTimeout(function() {$("#test").animate({"opacity":"0"})} , 1500 + 1000); // delays 1 sec after the previous one

If you're feeling lazy, here's a terse method of handling conditions using || (or) and && (and) after the operation:

wget -q --tries=10 --timeout=20 --spider http://google.com || \
{ echo "Sorry you are Offline" && exit 1; }

Here is simple way using HTML5 and jQuery:

1) include two JS file

<script src="jslibs/jquery.js" type="text/javascript"></script>
<script src="jslibs/ajaxupload-min.js" type="text/javascript"></script>

2) include CSS to have cool buttons

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

3) create DIV or SPAN

<div class="demo" > </div>

4) write this code in your HTML page

$('.demo').ajaxupload({
    url:'upload.php'
});

5) create you upload.php file to have PHP code to upload data.

You can download required JS file from here Here is Example

Are you sure you need to use sed? How about:

tr -d "\""

@dimas's answer is not logically consistent with your question; ifAllGranted cannot be directly replaced with hasAnyRole.

From the Spring Security 3—>4 migration guide:

Old:

<sec:authorize ifAllGranted="ROLE_ADMIN,ROLE_USER">
    <p>Must have ROLE_ADMIN and ROLE_USER</p>
</sec:authorize>

New (SPeL):

<sec:authorize access="hasRole('ROLE_ADMIN') and hasRole('ROLE_USER')">
    <p>Must have ROLE_ADMIN and ROLE_USER</p>
</sec:authorize>

Replacing ifAllGranted directly with hasAnyRole will cause spring to evaluate the statement using an OR instead of an AND. That is, hasAnyRole will return true if the authenticated principal contains at least one of the specified roles, whereas Spring's (now deprecated as of Spring Security 4) ifAllGranted method only returned true if the authenticated principal contained all of the specified roles.

TL;DR: To replicate the behavior of ifAllGranted using Spring Security Taglib's new authentication Expression Language, the hasRole('ROLE_1') and hasRole('ROLE_2') pattern needs to be used.

In the organizer you can click Share and save as iOS App Store Package(.ipa). You may also have to select 'Archive' from the 'Product' menu to generate the archive in the Organizer. Lastly, I think you have to have a properly signed archived build to do this.

There is an easier way than all of the above; You can use the PY_PYTHON environment variable. From inside the cmd.exe shell;

For the latest version of Python 2

set PY_PYTHON=2

For the latest version of Python 3

set PY_PYTHON=3

If you want it to be permanent, set it in the control panel. Or use setx instead of set in the cmd.exe shell.

This solution handles URL decoding:

var params = function() {
    function urldecode(str) {
        return decodeURIComponent((str+'').replace(/\+/g, '%20'));
    }

    function transformToAssocArray( prmstr ) {
        var params = {};
        var prmarr = prmstr.split("&");
        for ( var i = 0; i < prmarr.length; i++) {
            var tmparr = prmarr[i].split("=");
            params[tmparr[0]] = urldecode(tmparr[1]);
        }
        return params;
    }

    var prmstr = window.location.search.substr(1);
    return prmstr != null && prmstr != "" ? transformToAssocArray(prmstr) : {};
}();

Usage:

console.log('someParam GET value is', params['someParam']);

uint i = 10;
int j = (int)i;

or

int k = Convert.ToInt32(i)

You can use substring and strpos to accomplish this goal.

You could also use a regular expression to pattern match only what you want. Your mileage may vary on which of these approaches makes more sense.

It's not possible to save content to the website using only client-side scripting such as JavaScript and jQuery, but by submitting the data in an AJAX POST request you could perform the other half very easily on the server-side.

However, I would not recommend having raw content such as scripts so easily writeable to your hosting as this could easily be exploited. If you want to learn more about AJAX POST requests, you can read the jQuery API page:

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

And here are some things you ought to be aware of if you still want to save raw script files on your hosting. You have to be very careful with security if you are handling files like this!

File uploading (most of this applies if sending plain text too if javascript can choose the name of the file) http://www.developershome.com/wap/wapUpload/wap_upload.asp?page=security https://www.owasp.org/index.php/Unrestricted_File_Upload

Use

<table style="table-layout:fixed;">

It will force table to set to 100% width.Then use this code

$('#dataTable').dataTable( {
        bAutoWidth: false, 
        aoColumns : [
          { sWidth: '45%' },
          { sWidth: '45%' },
          { sWidth: '10%' },
              ]
      });

(table id is dataTable and having 3 column) to specify length to each cell

Step 1

Add the file name(s) to your .gitignore file.

Step 2

git filter-branch --force --index-filter \
    'git rm -r --cached --ignore-unmatch YOURFILE' \
    --prune-empty --tag-name-filter cat -- --all

Step 3

git push -f origin branch

A big thank you to @mu.

The "escape hatch" operation that lets you do weird things that are not otherwise supported by streams is to ask for an Iterator:

Iterator<T> it = users.stream().filter((user) -> user.getId() < 0).iterator();
if (!it.hasNext()) 
    throw new NoSuchElementException();
else {
    result = it.next();
    if (it.hasNext())
        throw new TooManyElementsException();
}

Guava has a convenience method to take an Iterator and get the only element, throwing if there are zero or multiple elements, which could replace the bottom n-1 lines here.

The where statement gets executed before the order by. So, your desired query is saying "take the first row and then order it by t_stamp desc". And that is not what you intend.

The subquery method is the proper method for doing this in Oracle.

If you want a version that works in both servers, you can use:

select ril.*
from (select ril.*, row_number() over (order by t_stamp desc) as seqnum
      from raceway_input_labo ril
     ) ril
where seqnum = 1

The outer * will return "1" in the last column. You would need to list the columns individually to avoid this.

A number of years ago (in the IE only days) I was using the <col align="right"> tag, but I just tested it and and it seems to be an IE only feature:

<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN"
    "http://www.w3.org/TR/html4/loose.dtd">
<html>
<head>
    <title>Test</title>
</head>
<body>
    <table width="100%" border="1">
        <col align="left" />
        <col align="left" />
        <col align="right" />
        <tr>
            <th>ISBN</th>
            <th>Title</th>
            <th>Price</th>
        </tr>
        <tr>
            <td>3476896</td>
            <td>My first HTML</td>
            <td>$53</td>
        </tr>
    </table>
</body>
</html>

The snippet is taken from www.w3schools.com. Of course, it should not be used (unless for some reason you really target the IE rendering engine only), but I thought it would be interesting to mention it.

Edit:

• IE still supports it.
• Firefox has dropped support in 3.5.
• Safari does not seem to support it, but the documentation indicates otherwise.

Overall, I don't understand the reasoning behing abandoning this tag. It would appear to be very useful (at least for manual HTML publishing).

Long ago it was impossible to reliably get the list of processes locking a file because Windows simply did not track that information. To support the Restart Manager API, that information is now tracked.

I put together code that takes the path of a file and returns a List<Process> of all processes that are locking that file.

Using from Limited Permission (e.g. IIS)

This call accesses the registry. If the process does not have permission to do so, you will get ERROR_WRITE_FAULT, meaning An operation was unable to read or write to the registry. You could selectively grant permission to your restricted account to the necessary part of the registry. It is more secure though to have your limited access process set a flag (e.g. in the database or the file system, or by using an interprocess communication mechanism such as queue or named pipe) and have a second process call the Restart Manager API.

Granting other-than-minimal permissions to the IIS user is a security risk.

@Liem Vo's answer is correct if you are using android.widget.Button without any overriding. If you are overriding your theme using MaterialComponents, this will not solve the issue.

So if you are

1. Using com.google.android.material.button.MaterialButton or
2. Overriding AppTheme using MaterialComponents

Use app:icon parameter.

<Button
    android:id="@+id/bSearch"
    android:layout_width="fill_parent"
    android:layout_height="wrap_content"
    android:padding="16dp"
    android:text="Search"
    android:textSize="24sp"
    app:icon="@android:drawable/ic_menu_search" />

I found deinit works good for me:

git submodule deinit <submodule-name>    
git rm <submodule-name>

From git docs:

deinit

Unregister the given submodules, i.e. remove the whole submodule.$name section from .git/config together with their work tree.

Just answering this old thread can be installed without pip On windows or Linux:

1) Download Requests from https://github.com/kennethreitz/requests click on clone or download button

2) Unzip the files in your python directory .Exp your python is installed in C:Python\Python.exe then unzip there

3) Depending on the Os run the following command:

• Windows use command cd to your python directory location then setup.py install
• Linux command: python setup.py install

Thats it :)

Sure you just need to setup a local web server. Check out XAMPP: http://www.apachefriends.org/en/xampp.html

That will get you up and running in about 10 minutes.

There is now a way to run php locally without installing a server: https://stackoverflow.com/a/21872484/672229

Yes but the files need to be processed. For example you can install test servers like mamp / lamp / wamp depending on your plateform.

Basically you need apache / php running.

First you need to check which SDK your Emulator is using and as @kuya suggested you need to follow those steps and install the latest version of that SDK Build Tool. Suppose your Emulator uses SDK 27 then you need to install latest in that series. For me it was 27.0.3. After that the error was gone.

Jquery Ajax will default send the data as query string parameters form like:

RecordId=456&UserId=123

unless the processData option is set to false, in which case it will sent as object to the server.

• contentType option is for the server that in which format client has sent the data.

• dataType option is for the server which tells that what type of data client is expecting back from the server.

Don't specify contentType so that server will parse them as query String parameters not as json.

OR

Use contentType as 'application/json; charset=utf-8' and use JSON.stringify(object) so that server would be able to deserialize json from string.

If your code should work in both Python 2 and 3, you can achieve this by loading this at the beginning of your program:

from __future__ import print_function   # If code has to work in Python 2 and 3!

Then you can print in the Python 3 way:

print("python")

If you want to print something without creating a new line - you can do this:

for number in range(0, 10):
    print(number, end=', ')

Try this one.

  String[] array1= new String[]{};
  System.out.println(array1.length);
  String[] array2= new String[0];
  System.out.println(array2.length);

Note: there is no byte code difference between new String[]{}; and new String[0];

new String[]{} is array initialization with values.

new String[0]; is array declaration(only allocating memory)

new String[10]{}; is not allowed because new String[10]{ may be here 100 values};

Change your main to:

public static void main(String[] args) {
    EchoServer echoServer = new EchoServer();
    echoServer.listen();
}

When you declare Object EchoServer0; you have a few mistakes.

1. EchoServer0 is of type Object, therefore it doesn't have the method listen().
2. You will also need to create an instance of it with new.
3. Another problem, this is only regarding naming conventions, you should call your variables starting by lower case letters, echoServer0 instead of EchoServer0. Uppercase names are usually for class names.
4. You should not create a variable with the same name as its class. It is confusing.

you can use valign="top" on the td tag it is working perfectly for me.

I have worked alot with msaccess vba. I think you are looking for MID function

example

    dim myReturn as string
    myreturn = mid("bonjour tout le monde",9,4)

will give you back the value "tout"

I know the OP says Recycle Bin. What I do though is recreate the file, especially if it's a single file. And when in the file, I just press CMD+Z (I'm on a Mac) and I get my file back.

1. Recreate the file in the same directory from where it was deleted.
2. CMD+Z inside of the newly created file.

The documentation has been updated. My answer has substantial changes vs the accepted answer: I wanted to reflect documentation is up-to-date, and accepted answer has a few broken links.

Also, I didn't understand when the accepted answer said "it defaults to node server.js". I think the documentation clarifies the default behavior:

npm-start

Start a package

Synopsis

npm start [-- <args>]

Description

This runs an arbitrary command specified in the package's "start" property of its "scripts" object. If no "start" property is specified on the "scripts" object, it will run node server.js.

In summary, running npm start could do one of two things:

1. npm start {command_name}: Run an arbitrary command (i.e. if such command is specified in the start property of package.json's scripts object)
2. npm start: Else if no start property exists (or no command_name is passed): Run node server.js, (which may not be appropriate, for example the OP doesn't have server.js; the OP runs nodeapp.js )
3. I said I would list only 2 items, but are other possibilities (i.e. error cases). For example, if there is no package.json in the directory where you run npm start, you may see an error: npm ERR! enoent ENOENT: no such file or directory, open '.\package.json'

Your solution is correct, but there is some redundancy in your regex.
The similar result can also be obtained from the following regex:

^([A-Z]{3})$

The {3} indicates that the [A-Z] must appear exactly 3 times.

Yes, you can modify local variables from inside lambdas (in the way shown by the other answers), but you should not do it. Lambdas have been made for functional style of programming and this means: No side effects. What you want to do is considered bad style. It is also dangerous in case of parallel streams.

You should either find a solution without side effects or use a traditional for loop.

I think one error in the original code might have been that it had:

$message = echo getRequestURI();

instead of:

$message = getRequestURI();

(The code has since been edited though.)

use the following code to apply some margin

$(".button").click(function() {
  $('html, body').animate({
    scrollTop: $(".scrolltothis").offset().top + 50;
  }, 500);
});

See this ans: Scroll down to div + a certain margin

That would be compilable code, as long as StringSecond was a class. However, if by "main method" you mean a second entry point into the program, then the answer to your question is still no. Only the first option (public static void main(String[] args)) can be the entry point into your program.

Note, however, that if you were to place a second main(String[]) method in a different class (but in the same project) you could have multiple possible entry points into the project which you could then choose from. But this cannot conflict with the principles of overriding or overloading.

Also note that one source of confusion in this area, especially for introductory programmers, is that public static void main(String[] args) and public static void main(String ... args) are both used as entry points and are treated as having the same method signature.

You need to use table-layout:fixed in order for CSS ellipsis to work on the table cells.

.table {
  table-layout:fixed;
}

.table td {
  white-space: nowrap;
  overflow: hidden;
  text-overflow: ellipsis;
}

demo: http://bootply.com/9njmoY2CmS

How do you iterate std::set?

int main(int argc,char *argv[]) 
{
    std::set<int> mset;
    mset.insert(1); 
    mset.insert(2);
    mset.insert(3);

    for ( auto it = mset.begin(); it != mset.end(); it++ )
        std::cout << *it;
}

In this case the user has done mistake in definition and its usage. If someone has done a typedef to a structure the same should be used without using struct following is the example.

typedef struct
{
   int a;
}studyT;

When using in a function

int main()
{
   struct studyT study; // This will give above error.
   studyT stud; // This will eliminate the above error.
   return 0;
}

You're specifying the table name twice. The ALTER TABLE part names the table. Try: Alter table TableName alter column [Date] default getutcdate()

This behaviour is now part of the component lifecycle.

A component can implement the ngOnChanges method in the OnChanges interface to get access to input changes.

Example:

import {Component, Input, OnChanges} from 'angular2/core';


@Component({
  selector: 'hero-comp',
  templateUrl: 'app/components/hero-comp/hero-comp.html',
  styleUrls: ['app/components/hero-comp/hero-comp.css'],
  providers: [],
  directives: [],

  pipes: [],
  inputs:['hero', 'real']
})
export class HeroComp implements OnChanges{
  @Input() hero:Hero;
  @Input() real:string;
  constructor() {
  }
  ngOnChanges(changes) {
      console.log(changes);
  }
}

Make sure that your Spring form mentions the modelAttribute="<Model Name".

Example:

@Controller
@RequestMapping("/greeting.html")
public class GreetingController {

 @ModelAttribute("greeting")
 public Greeting getGreetingObject() {
  return new Greeting();
 }

 /**
  * GET
  * 
  * 
  */
 @RequestMapping(method = RequestMethod.GET)
 public String handleRequest() {
  return "greeting";
 }

 /**
  * POST
  * 
  * 
  */
 @RequestMapping(method = RequestMethod.POST)
 public ModelAndView processSubmit(@ModelAttribute("greeting") Greeting greeting, BindingResult result){
  ModelAndView mv = new ModelAndView();
  mv.addObject("greeting", greeting);  
  return mv;
 }
}

In your JSP :

<form:form  modelAttribute="greeting" method="POST" action="greeting.html">

I had the same problem (exception 'Could not load NIB in bundle: ..') after upgrading my xcode from 3.2 to 4.02. Whereas deploying of my app with Xcode 3.2 worked fine it crashes with xcode 4 raising the exception mentioned above - but only when I tried to deploy to the IOS Simulator (v.4.2). Targeting the IOS device (v.4.1) acted also with Xcode 4.

It turned out (after hours of desperately scrabbling around) that the reason was an almost "hidden" setting in the .xib-file:

Visit the properties of the .xib files in the file inspector: The property 'Location' was set to 'Relative to Group' for all .xib files. I changed it to 'Relative to project' and voila: all .xib files now are correctly loaded in IOS simulator !

I have no clue what's the reason behind that for this odd Xcode4 behavior but maybe it's worth to make an attempt ?

They are:

• print only takes one parameter, while echo can have multiple parameters.
• print returns a value (1), so can be used as an expression.
• echo is slightly faster.

I had this problem and spent a few hours trying to fix it. I fixed the prefix error by changing the path but I still had an encoding import error. This was fixed by restarting my computer.

Without mod_expires it will be harder to set expiration headers on your files. For anything generated you can certainly set some default headers on the answer, doing the job of mod_expires like that:

<?php header('Expires: '.gmdate('D, d M Y H:i:s \G\M\T', time() + 3600)); ?>

(taken from: Stack Overflow answer from @brianegge, where the mod_expires solution is also explained)

Now this won't work for static files, like your javascript files. As for static files there is only apache (without any expiration module) between the browser and the source file. To prevent caching of javascript files, which is done on your browser, you can use a random token at the end of the js url, something like ?rd=45642111, so the url looks like:

<script type="texte/javascript" src="my/url/myjs.js?rd=4221159546">

If this url on the page is generated by a PHP file you can simply add the random part with PHP. This way of randomizing url by simply appending random query string parameters is the base thing upôn no-cache setting of ajax jQuery request for example. The browser will never consider 2 url having different query strings to be the same, and will never use the cached version.

EDIT

Note that you should alos test mod_headers. If you have mod_headers you can maybe set the Expires headers directly with the Header keyword.

I would say that the consultant is right in the theory, and you are right in practice. As the saying goes:

In theory, theory and practice are the same. In practice, they are not.

The Java spec says that System.gc suggests to call garbage collection. In practice, it just spawns a thread and runs right away on the Sun JVM.

Although in theory you could be messing up some finely tuned JVM implementation of garbage collection, unless you are writing generic code intended to be deployed on any JVM out there, don't worry about it. If it works for you, do it.

Tags <%= %> not works into a tag with runat="server". Move your code with <%= %> into runat="server" to an other tag (body, head, ...), or remove runat="server" from container.

If you have previously installed MySQL Workbench the problem is that another MySQL instance is running at 3306 port.

So uninstall MySQL and XAMPP and after that, reinstall only XAMPP.

This worked for me.

It is very convenient to use train_test_split without performing reindexing after dividing to several sets and not writing some additional code. Best answer above does not mention that by separating two times using train_test_split not changing partition sizes won`t give initially intended partition:

x_train, x_remain = train_test_split(x, test_size=(val_size + test_size))

Then the portion of validation and test sets in the x_remain change and could be counted as

new_test_size = np.around(test_size / (val_size + test_size), 2)
# To preserve (new_test_size + new_val_size) = 1.0 
new_val_size = 1.0 - new_test_size

x_val, x_test = train_test_split(x_remain, test_size=new_test_size)

In this occasion all initial partitions are saved.

There are two ways to download a file where the HTTP request requires that a header be set.

The credit for the first goes to @guest271314, and credit for the second goes to @dandavis.

The first method is to use the HTML5 File API to create a temporary local file, and the second is to use base64 encoding in conjunction with a data URI.

The solution I used in my project uses the base64 encoding approach for small files, or when the File API is not available, otherwise using the the File API approach.

Solution:

        var id = 123;

        var req = ic.ajax.raw({
            type: 'GET',
            url: '/api/dowloads/'+id,
            beforeSend: function (request) {
                request.setRequestHeader('token', 'token for '+id);
            },
            processData: false
        });

        var maxSizeForBase64 = 1048576; //1024 * 1024

        req.then(
            function resolve(result) {
                var str = result.response;

                var anchor = $('.vcard-hyperlink');
                var windowUrl = window.URL || window.webkitURL;
                if (str.length > maxSizeForBase64 && typeof windowUrl.createObjectURL === 'function') {
                    var blob = new Blob([result.response], { type: 'text/bin' });
                    var url = windowUrl.createObjectURL(blob);
                    anchor.prop('href', url);
                    anchor.prop('download', id+'.bin');
                    anchor.get(0).click();
                    windowUrl.revokeObjectURL(url);
                }
                else {
                    //use base64 encoding when less than set limit or file API is not available
                    anchor.attr({
                        href: 'data:text/plain;base64,'+FormatUtils.utf8toBase64(result.response),
                        download: id+'.bin',
                    });
                    anchor.get(0).click();
                }

            }.bind(this),
            function reject(err) {
                console.log(err);
            }
        );

Note that I'm not using a raw XMLHttpRequest, and instead using ic-ajax, and should be quite similar to a jQuery.ajax solution.

Note also that you should substitute text/bin and .bin with whatever corresponds to the file type being downloaded.

The implementation of FormatUtils.utf8toBase64 can be found here

We setup wildcard DNS like they explained above. So the a record is *.yourname.com

Then all of the subdomains are actually going to the same place, but PHP treats each subdomain as a different account.

We use the following code:

$url=$_SERVER["REQUEST_URI"];
$account=str_replace(".yourdomain.com","",$url);

This code just sets the $account variable the same as the subdomain. You could then retrieve their files and other information based on their account.

This probably isn't as efficient as the ways they list above, but if you don't have access to BIND and/or limited .htaccess this method should work (as long as your host will setup the wildcard for you).

We actually use this method to connect to the customers database for a multi-company e-commerce application, but it may work for you as well.

On a Mac, If you also have a similar problem, as Nenad Bulatovic mentioned above, you need to change the Binary Parsers.

Press Command + I to open up properties (or right click on your project and select property)

Make sure you select Mach-O 64 Parser.

You only need a minimal change; single-quote the here-document delimiter after <<.

cat <<'EOF' >> brightup.sh

or equivalently backslash-escape it:

cat <<\EOF >>brightup.sh

Without quoting, the here document will undergo variable substitution, backticks will be evaluated, etc, like you discovered.

If you need to expand some, but not all, values, you need to individually escape the ones you want to prevent.

cat <<EOF >>brightup.sh
#!/bin/sh
# Created on $(date # : <<-- this will be evaluated before cat;)
echo "\$HOME will not be evaluated because it is backslash-escaped"
EOF

will produce

#!/bin/sh
# Created on Fri Feb 16 11:00:18 UTC 2018
echo "$HOME will not be evaluated because it is backslash-escaped"

As suggested by @fedorqui, here is the relevant section from man bash:

Here Documents

This type of redirection instructs the shell to read input from the current source until a line containing only delimiter (with no trailing blanks) is seen. All of the lines read up to that point are then used as the standard input for a command.

The format of here-documents is:

      <<[-]word
              here-document
      delimiter

No parameter expansion, command substitution, arithmetic expansion, or pathname expansion is performed on word. If any characters in word are quoted, the delimiter is the result of quote removal on word, and the lines in the here-document are not expanded. If word is unquoted, all lines of the here-document are subjected to parameter expansion, command substitution, and arithmetic expansion. In the latter case, the character sequence \<newline> is ignored, and \ must be used to quote the characters \, $, and `.

please, something went xxx*x, and that's not true at all, check that

rs.MoveFirst

Do Until rs.EOF

am assuming that you want to know how to format numbers in SSRS

Just right click the TextBox on which you want to apply formatting, go to its expression.

suppose its expression is something like below

=Fields!myField.Value

then do this

=Format(Fields!myField.Value,"##.##") 

or

=Format(Fields!myFields.Value,"00.00")

difference between the two is that former one would make 4 as 4 and later one would make 4 as 04.00

this should give you an idea.

also: you might have to convert your field into a numerical one. i.e.

  =Format(CDbl(Fields!myFields.Value),"00.00")

so: 0 in format expression means, when no number is present, place a 0 there and # means when no number is present, leave it. Both of them works same when numbers are present ie. 45.6567 would be 45.65 for both of them:

UPDATE :

if you want to apply variable formatting on the same column based on row values i.e. you want myField to have no formatting when it has no decimal value but formatting with double precision when it has decimal then you can do it through logic. (though you should not be doing so)

Go to the appropriate textbox and go to its expression and do this:

=IIF((Fields!myField.Value - CInt(Fields!myField.Value)) > 0, 
    Format(Fields!myField.Value, "##.##"),Fields!myField.Value)

so basically you are using IIF(condition, true,false) operator of SSRS, ur condition is to check whether the number has decimal value, if it has, you apply the formatting and if no, you let it as it is.

this should give you an idea, how to handle variable formatting.

Go to your desired perspective. Go to 'Window->show view' menu.

If you see logcat there, click it and you are done.

Else, click on 'other' (at the bottom), chose 'Android'->logcat.

Hope that helps :-)

My understanding is that arrays are stored more efficiently (i.e. as contiguous blocks of memory vs. pointers to Python objects), but I am not aware of any performance benefit. Additionally, with arrays you must store primitives of the same type, whereas lists can store anything.

To a file:

require 'csv'
CSV.open("myfile.csv", "w") do |csv|
  csv << ["row", "of", "CSV", "data"]
  csv << ["another", "row"]
  # ...
end

To a string:

require 'csv'
csv_string = CSV.generate do |csv|
  csv << ["row", "of", "CSV", "data"]
  csv << ["another", "row"]
  # ...
end

Here's the current documentation on CSV: http://ruby-doc.org/stdlib/libdoc/csv/rdoc/index.html

Just stack two bootstrap tables; one for columns, the other for content. No plugins, just pure bootstrap (and that ain't no bs, haha!)

  <table id="tableHeader" class="table" style="table-layout:fixed">
        <thead>
            <tr>
                <th>Col1</th>
                ...
            </tr>
        </thead>
  </table>
  <div style="overflow-y:auto;">
    <table id="tableData" class="table table-condensed" style="table-layout:fixed">
        <tbody>
            <tr>
                <td>data</td>
                ...
            </tr>
        </tbody>
    </table>
 </div>

Demo JSFiddle

The content table div needs overflow-y:auto, for vertical scroll bars. Had to use table-layout:fixed, otherwise, columns did not line up. Also, had to put the whole thing inside a bootstrap panel to eliminate space between the tables.

Have not tested with custom column widths, but provided you keep the widths consistent between the tables, it should work.

    // ADD THIS JS FUNCTION TO MATCH UP COL WIDTHS
    $(function () {

        //copy width of header cells to match width of cells with data
        //so they line up properly
        var tdHeader = document.getElementById("tableHeader").rows[0].cells;
        var tdData = document.getElementById("tableData").rows[0].cells;

        for (var i = 0; i < tdData.length; i++)
            tdHeader[i].style.width = tdData[i].offsetWidth + 'px';

    });

I don't know that much JQuery but I've heard it allows to fire native events with this syntax.

$(document).ready(function(){

    $('#countrylist').change(function(e){
       // Your event handler
    });

    // And now fire change event when the DOM is ready
    $('#countrylist').trigger('change');
});

You must declare the change event handler before calling trigger() or change() otherwise it won't be fired. Thanks for the mention @LenielMacaferi.

More information here.

You could use jQuery and an Ajax call to post the specific update back to your server with Javascript.

It would look something like this:

function updatePostID(val, comment)
{

    var args = {};
    args.PostID = val;
    args.Comment = comment;

    $.ajax({
     type: "POST",
     url: controllerActionMethodUrlHere,
     contentType: "application/json; charset=utf-8",
     data: args,
     dataType: "json",
     success: function(msg) 
     {
        // Something afterwards here

     }
    });

}

On a Mac, open the Terminal (current user's directory should open), cd ".android" ("ls" to validate debug.keystore is there). Finally "rm debug.keystore" to remove the file.

Can't upvote so I'll repost @jfs comment cause I think it should be more visible.

@AnneTheAgile: shell=True is not required. Moreover you should not use it unless it is necessary (see @ valid's comment). You should pass each command-line argument as a separate list item instead e.g., use ['command', 'arg 1', 'arg 2'] instead of "command 'arg 1' 'arg 2'". – jfs Mar 3 '15 at 10:02

Does not solve the problem of network going down between checking and running your code but is fairly reliable

    // only recognizes changes related to Internet adapters
    if (System.Net.NetworkInformation.NetworkInterface.GetIsNetworkAvailable())
    {
        // however, this will include all adapters -- filter by opstatus and activity
        NetworkInterface[] interfaces = System.Net.NetworkInformation.NetworkInterface.GetAllNetworkInterfaces();
        return (from face in interfaces
                where face.OperationalStatus == OperationalStatus.Up
                where (face.NetworkInterfaceType != NetworkInterfaceType.Tunnel) && (face.NetworkInterfaceType != NetworkInterfaceType.Loopback)
                select face.GetIPv4Statistics()).Any(statistics => (statistics.BytesReceived > 0) && (statistics.BytesSent > 0));
    }

    return false;
}

From the documentation, you can apparently use either command to keep the file in the project history. Looks like you want remove, since it also deletes the file from the working directory.

From the Mercurial book at http://hgbook.red-bean.com/read/:

Removing a file does not affect its history. It is important to understand that removing a file has only two effects. It removes the current version of the file from the working directory. It stops Mercurial from tracking changes to the file, from the time of the next commit. Removing a file does not in any way alter the history of the file.

The man page hg(1) says this about forget:

Mark the specified files so they will no longer be tracked after the next commit. This only removes files from the current branch, not from the entire project history, and it does not delete them from the working directory.

And this about remove:

Schedule the indicated files for removal from the repository. This only removes files from the current branch, not from the entire project history.

If this is a command that you use often - you may want to consider having an alias for it as well. Add to your global .gitconfig:

[alias]
    hide = update-index --assume-unchanged
    unhide = update-index --no-assume-unchanged

How to set an alias (if you don't know already):

git config --configLocation alias.aliasName 'command --options'

Example:

git config --global alias.hide 'update-index --assume-unchanged'
git config... etc

After saving this to your .gitconfig, you can run a cleaner command.

git hide myfile.ext

or

git unhide myfile.ext

This git documentation was very helpful.

As per the comments, this is also a helpful alias to find out what files are currently being hidden:

[alias]
    hidden = ! git ls-files -v | grep '^h' | cut -c3-

There are several reasons to not parse HTML by regular expression. But, if you have total control of what HTML will be generated, then you can do with simple regular expression.

Above it's a function that parses HTML by regular expression. Note that this function is very sensitive and demands that the HTML obey certain rules, but it works very well in many scenarios. If you want a simple parser, and don't want to install libraries, give this a shot:

function array_combine_($keys, $values) {
    $result = array();
    foreach ($keys as $i => $k) {
        $result[$k][] = $values[$i];
    }
    array_walk($result, create_function('&$v', '$v = (count($v) == 1)? array_pop($v): $v;'));

    return $result;
}

function extract_data($str) {
    return (is_array($str))
        ? array_map('extract_data', $str)
        : ((!preg_match_all('#<([A-Za-z0-9_]*)[^>]*>(.*?)</\1>#s', $str, $matches))
            ? $str
            : array_map(('extract_data'), array_combine_($matches[1], $matches[2])));
}

print_r(extract_data(file_get_contents("http://www.google.com/")));

 void gen_random(char *s, size_t len) {
     for (size_t i = 0; i < len; ++i) {
         int randomChar = rand()%(26+26+10);
         if (randomChar < 26)
             s[i] = 'a' + randomChar;
         else if (randomChar < 26+26)
             s[i] = 'A' + randomChar - 26;
         else
             s[i] = '0' + randomChar - 26 - 26;
     }
     s[len] = 0;
 }

s=s.replaceAll("[*a-zA-Z]", "") replaces all alphabets

s=s.replaceAll("[*0-9]", "") replaces all numerics

if you do above two replaces you will get all special charactered string

If you want to extract only integers from a String s=s.replaceAll("[^0-9]", "")

If you want to extract only Alphabets from a String s=s.replaceAll("[^a-zA-Z]", "")

Happy coding :)

Unit Testing: It always performs by developer after their development done to find out issue from their testing side before they make any requirement ready for QA.

Integration Testing: It means tester have to verify module to sub module verification when some data/function output are drive to one module to other module. Or in your system if using third party tool which using your system data for integrate.

Smoke Testing: tester performed to verify system for high-level testing and trying to find out show stopper bug before changes or code goes live.

Regression Testing: Tester performed regression for verification of existing functionality due to changes implemented in system for newly enhancement or changes in system.

Simply like that :

<a id="myLink" onclick="alert('link click');">LINK 1</a>
<a id="myLink2" onclick="document.getElementById('myLink').click()">Click link 1</a>

or at page load :

<body onload="document.getElementById('myLink').click()">
...
<a id="myLink" onclick="alert('link click');">LINK 1</a>
...
</body>

The solution that i believe is best and optimized is:

try:
   #your code
except "ModelName".DoesNotExist:
   #your code

If you know the position of the date object in the string (for example in a log file), you can use .split()[index] to extract the date without fully knowing the format.

For example:

>>> string = 'monkey 2010-07-10 love banana'
>>> date = string.split()[1]
>>> date
'2010-07-10'

Log4j can be a bit confusing. So lets try to understand what is going on in this file: In log4j you have two basic constructs appenders and loggers.

Appenders define how and where things are appended. Will it be logged to a file, to the console, to a database, etc.? In this case you are specifying that log statements directed to fileAppender will be put in the file sample.log using the pattern specified in the layout tags. You could just as easily create a appender for the console or the database. Where the console appender would specify things like the layout on the screen and the database appender would have connection details and table names.

Loggers respond to logging events as they bubble up. If an event catches the interest of a specific logger it will invoke its attached appenders. In the example below you have only one logger the root logger - which responds to all logging events by default. In addition to the root logger you can specify more specific loggers that respond to events from specific packages. These loggers can have their own appenders specified using the appender-ref tags or will otherwise inherit the appenders from the root logger. Using more specific loggers allows you to fine tune the logging level on specific packages or to direct certain packages to other appenders.

So what this file is saying is:

1. Create a fileAppender that logs to file sample.log
2. Attach that appender to the root logger.
3. The root logger will respond to any events at least as detailed as 'debug' level
4. The appender is configured to only log events that are at least as detailed as 'info'

The net out is that if you have a logger.debug("blah blah") in your code it will get ignored. A logger.info("Blah blah"); will output to sample.log.

The snippet below could be added to the file above with the log4j tags. This logger would inherit the appenders from <root> but would limit the all logging events from the package org.springframework to those logged at level info or above.

  <!-- Example Package level Logger -->
    <logger name="org.springframework">
        <level value="info"/>
    </logger>   

I used this way in my code

$(function(){
    $('.block').affix();
})

Or if you just want to redefine the behavior of the console (in order to add logs for example) You can do something like that:

// define a new console
var console=(function(oldCons){
    return {
        log: function(text){
            oldCons.log(text);
            // Your code
        },
        info: function (text) {
            oldCons.info(text);
            // Your code
        },
        warn: function (text) {
            oldCons.warn(text);
            // Your code
        },
        error: function (text) {
            oldCons.error(text);
            // Your code
        }
    };
}(window.console));

//Then redefine the old console
window.console = console;

You have to use .onload

let canvas = document.getElementById("myCanvas");
let ctx = canvas.getContext("2d"); 

const drawImage = (url) => {
    const image = new Image();
    image.src = url;
    image.onload = () => {
       ctx.drawImage(image, 0, 0)
    }
}

Here's Why

If you are loading the image first after the canvas has already been created then the canvas won't be able to pass all the image data to draw the image. So you need to first load all the data that came with the image and then you can use drawImage()

Just to add one more point to this:

R does have a data structure equivalent to the Python dict in the hash package. You can read about it in this blog post from the Open Data Group. Here's a simple example:

> library(hash)
> h <- hash( keys=c('foo','bar','baz'), values=1:3 )
> h[c('foo','bar')]
<hash> containing 2 key-value pairs.
  bar : 2
  foo : 1

In terms of usability, the hash class is very similar to a list. But the performance is better for large datasets.

Perhaps you could think about the problem in a different way. WebClient and HttpClient are essentially different implementations of the same thing. What I recommend is implementing the Dependency Injection pattern with an IoC Container throughout your application. You should construct a client interface with a higher level of abstraction than the low level HTTP transfer. You can write concrete classes that use both WebClient and HttpClient, and then use the IoC container to inject the implementation via config.

What this would allow you to do would be to switch between HttpClient and WebClient easily so that you are able to objectively test in the production environment.

So questions like:

Will HttpClient be a better design choice if we upgrade to .Net 4.5?

Can actually be objectively answered by switching between the two client implementations using the IoC container. Here is an example interface that you might depend on that doesn't include any details about HttpClient or WebClient.

/// <summary>
/// Dependency Injection abstraction for rest clients. 
/// </summary>
public interface IClient
{
    /// <summary>
    /// Adapter for serialization/deserialization of http body data
    /// </summary>
    ISerializationAdapter SerializationAdapter { get; }

    /// <summary>
    /// Sends a strongly typed request to the server and waits for a strongly typed response
    /// </summary>
    /// <typeparam name="TResponseBody">The expected type of the response body</typeparam>
    /// <typeparam name="TRequestBody">The type of the request body if specified</typeparam>
    /// <param name="request">The request that will be translated to a http request</param>
    /// <returns></returns>
    Task<Response<TResponseBody>> SendAsync<TResponseBody, TRequestBody>(Request<TRequestBody> request);

    /// <summary>
    /// Default headers to be sent with http requests

HttpClient Implementation

You can use Task.Run to make WebClient run asynchronously in its implementation.

Dependency Injection, when done well helps alleviate the problem of having to make low level decisions upfront. Ultimately, the only way to know the true answer is try both in a live environment and see which one works the best. It's quite possible that WebClient may work better for some customers, and HttpClient may work better for others. This is why abstraction is important. It means that code can quickly be swapped in, or changed with configuration without changing the fundamental design of the app.

BTW: there are numerous other reasons that you should use an abstraction instead of directly calling one of these low-level APIs. One huge one being unit-testability.

if (yourObject instanceof yourClassName) will evaluate to false if yourObject is null.

Hi - I want to write a test to establish that an Exception is not raised in a given circumstance.

That's the default assumption -- exceptions are not raised.

If you say nothing else, that's assumed in every single test.

You don't have to actually write an any assertion for that.

If anyone else runs into this, the issue we had was that we were making the ajax request from a link, and not preventing the link from being followed. So if you are doing this in an onclick attribute, make sure to return false; as well.

The guid provided is not correct format(.net Provided guid).

begin try
select convert(uniqueidentifier,'a89b1acd95016ae6b9c8aabb07da2010')
end try
begin catch
print '1'
end catch

I eventually figured out an easy way to do it:

1. On your Twitter feed, click the date/time of the tweet containing the video. That will open the single tweet view
2. Look for the down-pointing arrow at the top-right corner of the tweet, click it to open drop-down menue
3. Select the "Embed Video" option and copy the HTML embed code and Paste it to Notepad
4. Find the last "t.co" shortened URL inside the HTML code (should be something like this: https://``t.co/tQM43ftXyM). Copy this URL and paste it in a new browser tab.
5. The browser will expand the shortened URL to something which looks like this: https://twitter.com/UserName/status/828267001496784896/video/1

This is the link to the Twitter Card containing the native video. Pasting this link in a new tweet or DM will include the native video in it!

Are you looking for the max date for each model?

SELECT model, max(date) FROM doc
GROUP BY model

If you're looking for all models matching the max date of the entire table...

SELECT model, date FROM doc
WHERE date IN (SELECT max(date) FROM doc)

[--- Added ---]

For those who want to display details from every record matching the latest date within each model group (not summary data, as asked for in the OP):

SELECT d.model, d.date, d.color, d.etc FROM doc d
WHERE d.date IN (SELECT max(d2.date) FROM doc d2 WHERE d2.model=d.model)

MySQL 8.0 and newer supports the OVER clause, producing the same results a bit faster for larger data sets.

SELECT model, date, color, etc FROM (SELECT model, date, color, etc, 
  max(date) OVER (PARTITION BY model) max_date FROM doc) predoc 
WHERE date=max_date;

I solved it myself for the time being. The original value has only 2 sub-properties. I reformed a new object with the properties from a and then assigned it to b. Now my event handler updates only b, and my original a stays as it is.

var a = { key1: 'value1', key2: 'value2' },
    b = a;

$('#revert').on('click', function(e){
    //FAIL!
    b = a;

    //WIN
    b = { key1: a.key1, key2: a.key2 };
});

This works fine. I have not changed a single line anywhere in my code except for the above, and it works just how I wanted it to. So, trust me, nothing else was updating a.

This will download all packages and dependencies (no already installed) to a directory of your choice:

sudo apt-get install -d -o Dir::Cache=/path-to/directory/apt/cache -o Dir::State::Lists=/path-to/directory/apt/lists packages

Make sure /path-to/directory/apt/cache and /path-to/directory/apt/lists exist. If you don't set -o Dir::Cache it points to /var/cache/apt, Dir::State::Lists points to /var/lib/apt/lists (which keeps the index files of available packages)

Both -o options can be used with update and upgrade instead of install.

On different machine run the same command without '-d'

Your file seems quite small (297 lines) so you can read and write them quite quickly. You refer to Excel CSV, which does not exists, and you show space delimited data in your example. Furthermore, Access is limited to 255 columns, and a CSV is not, so there is no guarantee this will work

Sub StripHeaderAndFooter()
Dim fs As Object ''FileSystemObject
Dim tsIn As Object, tsOut As Object ''TextStream
Dim sFileIn As String, sFileOut As String
Dim aryFile As Variant

    sFileIn = "z:\docs\FileName.csv"
    sFileOut = "z:\docs\FileOut.csv"

    Set fs = CreateObject("Scripting.FileSystemObject")
    Set tsIn = fs.OpenTextFile(sFileIn, 1) ''ForReading

    sTmp = tsIn.ReadAll

    Set tsOut = fs.CreateTextFile(sFileOut, True) ''Overwrite
    aryFile = Split(sTmp, vbCrLf)

    ''Start at line 3 and end at last line -1
    For i = 3 To UBound(aryFile) - 1
        tsOut.WriteLine aryFile(i)
    Next

    tsOut.Close

    DoCmd.TransferText acImportDelim, , "NewCSV", sFileOut, False
End Sub

Edit re various comments

It is possible to import a text file manually into MS Access and this will allow you to choose you own cell delimiters and text delimiters. You need to choose External data from the menu, select your file and step through the wizard.

About importing and linking data and database objects -- Applies to: Microsoft Office Access 2003

Introduction to importing and exporting data -- Applies to: Microsoft Access 2010

Once you get the import working using the wizards, you can save an import specification and use it for you next DoCmd.TransferText as outlined by @Olivier Jacot-Descombes. This will allow you to have non-standard delimiters such as semi colon and single-quoted text.

I'll just try to answer the question but my examples very simple because I'm new at mvc. Hope this help somebody.

    [HttpPost]  ///This function is in my controller class
    public ActionResult Delete(string txtDelete)
    {
        int _id = Convert.ToInt32(txtDelete); // put your code           
    }

This code is in my controller's cshtml

  >   @using (Html.BeginForm("Delete", "LibraryManagement"))
 {
<button>Delete</button>
@Html.Label("Enter an ID number");
@Html.TextBox("txtDelete")  }  

Just make sure the textbox name and your controller's function input are the same name and type(string).This way, your function get the textbox input.

Once you remove the ID "page_navigation" that element no longer has an ID and so cannot be found when you attempt to access it a second time.

The solution is to cache a reference to the element:

$(document).ready(function(){
    // This reference remains available to the following functions
    // even when the ID is removed.
    var page_navigation = $("#page_navigation1");

    $("#add").click(function(){
        page_navigation.attr("id","page_navigation1");
    });     

    $("#remove").click(function(){
        page_navigation.removeAttr("id");
    });     
});

Here's one that is pure css that uses the + next sibling selector, :hover, and pointer-events. It doesn't use an imagemap, technically, but the rect concept totally carries over:

.hotspot {_x000D_
    position: absolute;_x000D_
    border: 1px solid blue;_x000D_
}_x000D_
.hotspot + * {_x000D_
    pointer-events: none;_x000D_
    opacity: 0;_x000D_
}_x000D_
.hotspot:hover + * {_x000D_
    opacity: 1.0;_x000D_
}_x000D_
.wash {_x000D_
    position: absolute;_x000D_
    top: 0;_x000D_
    left: 0;_x000D_
    bottom: 0;_x000D_
    right: 0;_x000D_
    background-color: rgba(255, 255, 255, 0.6);_x000D_
}

<div style="position: relative; height: 188px; width: 300px;">_x000D_
    <img src="http://demo.cloudimg.io/s/width/300/sample.li/boat.jpg">_x000D_
        _x000D_
    <div class="hotspot" style="top: 50px; left: 50px; height: 30px; width: 30px;"></div>_x000D_
    <div>_x000D_
        <div class="wash"></div>_x000D_
        <div style="position: absolute; top: 0; left: 0;">A</div>_x000D_
    </div>_x000D_
        _x000D_
    <div class="hotspot" style="top: 100px; left: 120px; height: 30px; width: 30px;"></div>_x000D_
    <div>_x000D_
        <div class="wash"></div>_x000D_
        <div style="position: absolute; top: 0; left: 0;">B</div>_x000D_
    </div>_x000D_
</div>

Both do the same work as they are used for routing purposes in SPA(Single Page Application).

1. Angular Routing - per $routeProvider docs

URLs to controllers and views (HTML partials). It watches $location.url() and tries to map the path to an existing route definition.

HTML

<div ng-view></div>

Above tag will render the template from the $routeProvider.when() condition which you had mentioned in .config (configuration phase) of angular

Limitations:-

• The page can only contain single ng-view on page
• If your SPA has multiple small components on the page that you wanted to render based on some conditions, $routeProvider fails. (to achieve that, we need to use directives like ng-include, ng-switch, ng-if, ng-show, which looks bad to have them in SPA)
• You can not relate between two routes like parent and child relationship.
• You cannot show and hide a part of the view based on url pattern.

2. ui-router - per $stateProvider docs

AngularUI Router is a routing framework for AngularJS, which allows you to organize the parts of your interface into a state machine. UI-Router is organized around states, which may optionally have routes, as well as other behavior, attached.

Multiple & Named Views

Another great feature is the ability to have multiple ui-views in a template.

While multiple parallel views are a powerful feature, you'll often be able to manage your interfaces more effectively by nesting your views, and pairing those views with nested states.

HTML

<div ui-view>
    <div ui-view='header'></div>
    <div ui-view='content'></div>
    <div ui-view='footer'></div>
</div>

The majority of ui-router's power is it can manage nested state & views.

Pros

• You can have multiple ui-view on single page
• Various views can be nested in each other and maintained by defining state in routing phase.
• We can have child & parent relationship here, simply like inheritance in state, also you could define sibling states.
• You could change the ui-view="some" of state just by using absolute routing using @ with state name.
• Another way you could do relative routing is by using only @ to change ui-view="some". This will replace the ui-view rather than checking if it is nested or not.
• Here you could use ui-sref to create a href URL dynamically on the basis of URL mentioned in a state, also you could give a state params in the json format.

For more Information Angular ui-router

For better flexibility with various nested view with states, I'd prefer you to go for ui-router

There is an option to generate php5 objects with WsdlInterpreter class. See more here: https://github.com/gkwelding/WSDLInterpreter

for example:

require_once 'WSDLInterpreter-v1.0.0/WSDLInterpreter.php';
$wsdlLocation = '<your wsdl url>?wsdl';
$wsdlInterpreter = new WSDLInterpreter($wsdlLocation);
$wsdlInterpreter->savePHP('.');

It looks like a location problem because that code is perfectly fine for adding the icon.

Since I don't know your folder structure, I suggest adding a simple check:

File imageCheck = new File("water.bmp");

if(imageCheck.exists()) 
    System.out.println("Image file found!")
else 
    System.out.println("Image file not found!");

This way if you ever get your path name wrong it will tell you instead of displaying nothing. Exception should be thrown if file would not exist, tho.

Note that none of these answers will work if the key is a varchar since it is tempting to use MAX in a varchar column that is filled with "ints".

In a database if a column e.g. "Id" is in the database 1,2,3, 110, 112, 113, 4, 5, 6 Then all of the answers above will return 6.

So in your local database everything will work fine since while developing you will never get above 100 test records, then, at some moment during production you get a weird support ticket. Then after an hour you discover exactly this line "max" which seems to return the wrong key for some reason....

(and note that it says nowhere above that the key is INT...) (and if happens to end up in a generic library...)

So use:

Users.OrderByDescending(x=>x.Id.Length).ThenByDescending(a => a.Id).FirstOrDefault();

In Java Class:

    public class EnumTest{
    //Other property link
    private String name;
    ....

        public enum Status {
                ACTIVE,NEWLINK, BROADCASTED, PENDING, CLICKED, VERIFIED, AWARDED, INACTIVE, EXPIRED, DELETED_BY_ADMIN;
            }

        private Status statusobj ;

    //Getter and Setters
}

So now POJO and enum obj is created. Now EnumTest you will set in session object using in the servlet or controller class session.setAttribute("enumTest", EnumTest );

In JSP Page

<c:if test="${enumTest.statusobj == 'ACTIVE'}">

//TRUE??? THEN PROCESS SOME LOGIC

You can subscribe to route changes and store the current event so you can use it when the next happens

previousUrl: string;
constructor(router: Router) {
  router.events
  .pipe(filter(event => event instanceof NavigationEnd))
  .subscribe((event: NavigationEnd) => {
    console.log('prev:', event.url);
    this.previousUrl = event.url;
  });
}

See also How to detect a route change in Angular?

One additional idea, mentioned here is to use a regular expression to check:

SELECT  foo 
FROM    bar
WHERE   REGEXP_LIKE (foo,'^[[:digit:]]+$');

The nice part is you do not need a separate PL/SQL function. The potentially problematic part is that a regular expression may not be the most efficient method for a large number of rows.

If you have some changes on your workspace and you want to stash them into a new branch use this command:

git stash branch branchName

It will make:

1. a new branch
2. move changes to this branch
3. and remove latest stash (Like: git stash pop)

Approaches 1 and 2 obviously don't work, because you get java.sql.Date objects, per JPA/Hibernate spec, and not java.util.Date. From approaches 3 and 4, I would rather choose the latter one, because it's more declarative, and will work with both field and getter annotations.

You have already laid out the solution 4 in your referenced blog post, as @tscho was kind to point out. Maybe defaultForType (see below) should give you the centralized solution you were looking for. Of course will will still need to differentiate between date (without time) and timestamp fields.

For future reference I will leave the summary of using your own Hibernate UserType here:

To make Hibernate give you java.util.Date instances, you can use the @Type and @TypeDef annotations to define a different mapping of your java.util.Date java types to and from the database.

See the examples in the core reference manual here.

1. Implement a UserType to do the actual plumbing (conversion to/from java.util.Date), named e.g. TimestampAsJavaUtilDateType

2. Add a @TypeDef annotation on one entity or in a package-info.java - both will be available globally for the session factory (see manual link above). You can use defaultForType to apply the type conversion on all mapped fields of type java.util.Date.

   @TypeDef
     name = "timestampAsJavaUtilDate",
     defaultForType = java.util.Date.class, /* applied globally */
     typeClass = TimestampAsJavaUtilDateType.class
   )
   

3. Optionally, instead of defaultForType, you can annotate your fields/getters with @Type individually:

   @Entity
   public class MyEntity {
      [...]
      @Type(type="timestampAsJavaUtilDate")
      private java.util.Date myDate;
      [...]
   }
   

P.S. To suggest a totally different approach: we usually just don't compare Date objects using equals() anyway. Instead we use a utility class with methods to compare e.g. only the calendar date of two Date instances (or another resolution such as seconds), regardless of the exact implementation type. That as worked well for us.
