In my case it resolves by adding configuration.addAnnotatedClass(com.myApp.model.Example.class); after Configuration configuration = new Configuration().configure(HibernateUtil.class.getResource("/hibernate.cfg.xml")); in hibernateUtill class. It Read a mapping from the class annotation metadata . Read more about addAnnotatedClass() from here.

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

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

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

So, change the projection like so:

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

Try this:

$objPHPExcel->getActiveSheet()->getRowDimension('1')->setRowHeight(40);

            };

            Session session = Session.getDefaultInstance( properties , authenticator);  
          try{
             // Create a default MimeMessage object.
             MimeMessage message = new MimeMessage(session);

             // Set From: header field of the header.
             message.setFrom(new InternetAddress(from));

             // Set To: header field of the header.
             message.addRecipient(Message.RecipientType.TO,
                                      new InternetAddress(to));

             // Set Subject: header field
             message.setSubject("This is the Subject Line!");

             // Now set the actual message
             message.setText("This is actual message");

             // Send message

             System.out.println("Sent message successfully....");
          }catch (MessagingException mex) {
             mex.printStackTrace();
          }
    }

}

boolean can only be true or false because it's a primitive datatype (+ a boolean variables default value is false). You can use the class Boolean instead if you want to use null values. Boolean is a reference type, that's the reason you can assign null to a Boolean "variable". Example:

Boolean testvar = null;
if (testvar == null) { ...}

Try this for range of cells:

$from = "A1"; // or any value
$to = "B5"; // or any value
$objPHPExcel->getActiveSheet()->getStyle("$from:$to")->getFont()->setBold( true );

or single cell

$cell_name = "A1";
$objPHPExcel->getActiveSheet()->getStyle( $cell_name )->getFont()->setBold( true );

hope that helps

Everywhere inside the query string, the wildcard should be ? instead of '?'. That should solve the problem.

EDIT :

To add to that, you need to change date '?' to to_date(?, 'yyyy-mm-dd'). Please try that and let me know.

var i2 = JsonConvert.DeserializeObject(obj["id"].ToString(), type);

throws a parsing exception due to missing quotes around the first argument (I think). I got it to work by adding the quotes:

var i2 = JsonConvert.DeserializeObject("\"" + obj["id"].ToString() + "\"", type);

To append to an array, just use the += operator.

$Target += $TargetObject

Also, you need to declare $Target = @() before your loop because otherwise, it will empty the array every loop.

I think the difference between the two boils down to access. Environment variables are accessible by any process and Java system properties are only accessible by the process they are added to.

Also as Bohemian stated, env variables are set in the OS (however they 'can' be set through Java) and system properties are passed as command line options or set via setProperty().

I struggled to get this working. That's why I'll add a complete solution here:

My objective is to add this header to the SOAP envelope:

   <soapenv:Header>
      <urn:OTAuthentication>
         <urn:AuthenticationToken>TOKEN</urn:AuthenticationToken>
      </urn:OTAuthentication>
   </soapenv:Header>

1. First create a SOAPHeaderHandler class.

   import java.util.Set;
   import java.util.TreeSet;
   
   import javax.xml.namespace.QName;
   import javax.xml.soap.SOAPElement;
   import javax.xml.soap.SOAPEnvelope;
   import javax.xml.soap.SOAPFactory;
   import javax.xml.soap.SOAPHeader;
   import javax.xml.ws.handler.MessageContext;
   import javax.xml.ws.handler.soap.SOAPHandler;
   import javax.xml.ws.handler.soap.SOAPMessageContext;
   
   public class SOAPHeaderHandler implements SOAPHandler<SOAPMessageContext> {
   
       private final String authenticatedToken;
   
       public SOAPHeaderHandler(String authenticatedToken) {
           this.authenticatedToken = authenticatedToken;
       }
   
       public boolean handleMessage(SOAPMessageContext context) {
           Boolean outboundProperty =
                   (Boolean) context.get(MessageContext.MESSAGE_OUTBOUND_PROPERTY);
           if (outboundProperty.booleanValue()) {
               try {
                   SOAPEnvelope envelope = context.getMessage().getSOAPPart().getEnvelope();
                   SOAPFactory factory = SOAPFactory.newInstance();
                   String prefix = "urn";
                   String uri = "urn:api.ecm.opentext.com";
                   SOAPElement securityElem =
                           factory.createElement("OTAuthentication", prefix, uri);
                   SOAPElement tokenElem =
                           factory.createElement("AuthenticationToken", prefix, uri);
                   tokenElem.addTextNode(authenticatedToken);
                   securityElem.addChildElement(tokenElem);
                   SOAPHeader header = envelope.addHeader();
                   header.addChildElement(securityElem);
               } catch (Exception e) {
                   e.printStackTrace();
               }
           } else {
               // inbound
           }
           return true;
       }
   
       public Set<QName> getHeaders() {
           return new TreeSet();
       }
   
       public boolean handleFault(SOAPMessageContext context) {
           return false;
       }
   
       public void close(MessageContext context) {
           //
       }
   }
   

   2. Add the handler to the proxy. Note that according javax.xml.ws.Binding's documentation: "If the returned chain is modified a call to setHandlerChain is required to configure the binding instance with the new chain."

   Authentication_Service authentication_Service = new Authentication_Service();
   
   Authentication basicHttpBindingAuthentication = authentication_Service.getBasicHttpBindingAuthentication();
   String authenticatedToken = "TOKEN";
   List<Handler> handlerChain = ((BindingProvider)basicHttpBindingAuthentication).getBinding().getHandlerChain();
   handlerChain.add(new SOAPHeaderHandler(authenticatedToken));
   ((BindingProvider)basicHttpBindingAuthentication).getBinding().setHandlerChain(handlerChain);
   

The mail server on CentOS 6 and other IPv6 capable server platforms may be bound to IPv6 localhost (::1) instead of IPv4 localhost (127.0.0.1).

Typical symptoms:

[root@host /]# telnet 127.0.0.1 25
Trying 127.0.0.1...
telnet: connect to address 127.0.0.1: Connection refused

[root@host /]# telnet localhost 25
Trying ::1...
Connected to localhost.
Escape character is '^]'.
220 host ESMTP Exim 4.72 Wed, 14 Aug 2013 17:02:52 +0100

[root@host /]# netstat -plant | grep 25
tcp        0      0 :::25                       :::*                        LISTEN      1082/exim           

If this happens, make sure that you don't have two entries for localhost in /etc/hosts with different IP addresses, like this (bad) example:

[root@host /]# cat /etc/hosts
127.0.0.1 localhost.localdomain localhost localhost4.localdomain4 localhost4
::1       localhost localhost.localdomain localhost6 localhost6.localdomain6

To avoid confusion, make sure you only have one entry for localhost, preferably an IPv4 address, like this:

[root@host /]# cat /etc/hosts
127.0.0.1 localhost  localhost.localdomain   localhost4.localdomain4 localhost4
::1       localhost6 localhost6.localdomain6

In short: this happens likely when you are hot-deploying webapps. For instance, your ide+development server hot-deploys a war again. Threads, that have been created previously are still running. But meanwhile their classloader/context is invalid and faces the IllegalAccessException / IllegalStateException becouse its orgininating webapp (the former runtime-environment) has been redeployed.

So, as states here, a restart does not permanently resolve this issue. Instead, it is better to find/implement a managed Thread Pool, s.th. like this to handle the termination of threads appropriately. In JavaEE you will use these ManagedThreadExeuctorServices. A similar opinion and reference here.

Examples for this are the EvictorThread of Apache Commons Pool, that "cleans" pooled instances according to the pool's configuration (max idle etc.).

Of cause it's possible to create dynamic classes using very cool ExpandoObject class. But recently I worked on project and faced that Expando Object is serealized in not the same format on xml as an simple Anonymous class, it was pity =( , that is why I decided to create my own class and share it with you. It's using reflection and dynamic directive , builds Assembly, Class and Instance truly dynamicly. You can add, remove and change properties that is included in your class on fly Here it is :

            public Dictionary<string, string> Contacts { get; set; }
        }

    }
}

It is also very simple to use DynamicTypeBuilder, you just need put few lines like this:

    public class ExampleOfUse
    {
        private readonly bool includeAddress;
        private readonly bool includeFacebook;
        private readonly dynamic dynamicType;
        private readonly List<ClassDescriptorKeyValue> classDiscriptionList;
        public ExampleOfUse(bool includeAddress = false, bool includeFacebook = false)
        {
            this.includeAddress = includeAddress;
            this.includeFacebook = includeFacebook;
            this.classDiscriptionList = DynamicTypeBuilderTest.GetAnonymousClassDescription(includeAddress, includeFacebook).ToList();
            this.dynamicType = DynamicTypeBuilderTest.CreateAnonymousDynamicType("VeryPrivateData", this.classDiscriptionList);
        }

        public object Map(PersonalData privateInfo)
        {
            object dynamicObject = DynamicTypeBuilderTest.CreateAnonymousDynamicInstance(privateInfo, this.dynamicType, classDiscriptionList);

            return dynamicObject;
        }

    }

I hope that this code snippet help somebody =) Enjoy!

Use PropertyInfo.PropertyType to get the type of the property.

public bool ValidateData(object data)
{
    foreach (PropertyInfo propertyInfo in data.GetType().GetProperties())
    {
        if (propertyInfo.PropertyType == typeof(string))
        {
            string value = propertyInfo.GetValue(data, null);

            if value is not OK
            {
                return false;
            }
        }
    }            

    return true;
}

Try this out. it works well for me. Make sure that before send email u need to give the access for less secure app in your gmail account. So go to the following link and try out with this java code.
Activate gmail for less secure app

You need to import javax.mail.jar file and activation.jar file to your project.

This is the full code for send email in java

import javax.mail.*;
import javax.mail.internet.*;
import java.util.*;

public class SendEmail {

    final String senderEmail = "your email address";
    final String senderPassword = "your password";
    final String emailSMTPserver = "smtp.gmail.com";
    final String emailServerPort = "587";
    String receiverEmail = null;
    String emailSubject = null;
    String emailBody = null;

    public SendEmail(String receiverEmail, String Subject, String message) {
        this.receiverEmail = receiverEmail;
        this.emailSubject = Subject;
        this.emailBody = message;

        Properties props = new Properties();
        props.put("mail.smtp.user", senderEmail);
        props.put("mail.smtp.host", emailSMTPserver);
        props.put("mail.smtp.port", emailServerPort);
        props.put("mail.smtp.starttls.enable", "true");
        props.put("mail.smtp.auth", "true");
        props.put("mail.smtp.socketFactory.port", emailServerPort);
        props.put("mail.smtp.socketFactory.class", "javax.net.ssl.SSLSocketFactory");

        SecurityManager security = System.getSecurityManager();

        try {
            Authenticator auth = new SMTPAuthenticator();
            Session session = Session.getInstance(props, auth);

            Message msg = new MimeMessage(session);
            msg.setText(emailBody);
            msg.setSubject(emailSubject);
            msg.setFrom(new InternetAddress(senderEmail));
            msg.addRecipient(Message.RecipientType.TO,
                    new InternetAddress(receiverEmail));
            Transport.send(msg);
            System.out.println("send successfully");
        } catch (Exception ex) {
            System.err.println("Error occurred while sending.!");
        }

    }

    private class SMTPAuthenticator extends javax.mail.Authenticator {

        public PasswordAuthentication getPasswordAuthentication() {
            return new PasswordAuthentication(senderEmail, senderPassword);
        }
    }

    public static void main(String[] args) {
        SendEmail send = new SendEmail("receiver email address", "subject", "message");
    }

}

The solution I end up using most is based off of Tomas Petricek's answer. I usually want to do something with both the attribute and property.

var props = from p in this.GetType().GetProperties()
            let attr = p.GetCustomAttributes(typeof(MyAttribute), true)
            where attr.Length == 1
            select new { Property = p, Attribute = attr.First() as MyAttribute};

You need to implement a custom Authenticator

import javax.mail.Authenticator;
import javax.mail.PasswordAuthentication;


class GMailAuthenticator extends Authenticator {
     String user;
     String pw;
     public GMailAuthenticator (String username, String password)
     {
        super();
        this.user = username;
        this.pw = password;
     }
    public PasswordAuthentication getPasswordAuthentication()
    {
       return new PasswordAuthentication(user, pw);
    }
}

Now use it in the Session

Session session = Session.getInstance(props, new GMailAuthenticator(username, password));

This might not be the best way to do it. But it somehow worked for me, so i'm going to run with it.

In my php function that returns the data, one line before the return line, I add an echo statement, echoing the data I want to send.

Now sure why it worked, but it did.

The answer of delfuego is the simplest way to solve the certificate problem. But, in my case, one of our third party url (using https), updated their certificate every 2 months automatically. It means that I have to import the cert to our Java trust store manually every 2 months as well. Sometimes it caused production problems.

So, I made a method to solve it with SecureRestClientTrustManager to be able to consume https url without importing the cert file. Here is the method:

     public static String doPostSecureWithHeader(String url, String body, Map headers)
            throws Exception {
        log.info("start doPostSecureWithHeader " + url + " with param " + body);
        long startTime;
        long endTime;
        startTime = System.currentTimeMillis();
        Client client;
        client = Client.create();
        WebResource webResource;
        webResource = null;
        String output = null;
        try{
            SSLContext sslContext = null;
            SecureRestClientTrustManager secureRestClientTrustManager = new SecureRestClientTrustManager();
            sslContext = SSLContext.getInstance("SSL");
            sslContext
            .init(null,
                    new javax.net.ssl.TrustManager[] { secureRestClientTrustManager },
                    null);
            DefaultClientConfig defaultClientConfig = new DefaultClientConfig();
            defaultClientConfig
            .getProperties()
            .put(com.sun.jersey.client.urlconnection.HTTPSProperties.PROPERTY_HTTPS_PROPERTIES,
                    new com.sun.jersey.client.urlconnection.HTTPSProperties(
                            getHostnameVerifier(), sslContext));

            client = Client.create(defaultClientConfig);
            webResource = client.resource(url);

            if(headers!=null && headers.size()>0){
                for (Map.Entry entry : headers.entrySet()){
                    webResource.setProperty(entry.getKey(), entry.getValue());
                }
            }
            WebResource.Builder builder = 
                    webResource.accept("application/json");
            if(headers!=null && headers.size()>0){

                    builder.header(entry.getKey(), entry.getValue());
                }
            }

            ClientResponse response = builder
                    .post(ClientResponse.class, body);
            output = response.getEntity(String.class);
        }
        catch(Exception e){
            log.error(e.getMessage(),e);
            if(e.toString().contains("One or more of query value parameters are null")){
                output="-1";
            }
            if(e.toString().contains("401 Unauthorized")){
                throw e;
            }
        }
        finally {
            if (client!= null) {
                client.destroy();

HTTPS proxy doesn't make sense because you can't terminate your HTTP connection at the proxy for security reasons. With your trust policy, it might work if the proxy server has a HTTPS port. Your error is caused by connecting to HTTP proxy port with HTTPS.

You can connect through a proxy using SSL tunneling (many people call that proxy) using proxy CONNECT command. However, Java doesn't support newer version of proxy tunneling. In that case, you need to handle the tunneling yourself. You can find sample code here,

http://www.javaworld.com/javaworld/javatips/jw-javatip111.html

EDIT: If you want defeat all the security measures in JSSE, you still need your own TrustManager. Something like this,

 public SSLTunnelSocketFactory(String proxyhost, String proxyport){
      tunnelHost = proxyhost;
      tunnelPort = Integer.parseInt(proxyport);
      dfactory = (SSLSocketFactory)sslContext.getSocketFactory();
 }

 ...

 connection.setSSLSocketFactory( new SSLTunnelSocketFactory( proxyHost, proxyPort ) );
 connection.setDefaultHostnameVerifier( new HostnameVerifier()
 {
    public boolean verify( String arg0, SSLSession arg1 )
    {
        return true;
    }
 }  );

EDIT 2: I just tried my program I wrote a few years ago using SSLTunnelSocketFactory and it doesn't work either. Apparently, Sun introduced a new bug sometime in Java 5. See this bug report,

http://bugs.sun.com/view_bug.do?bug_id=6614957

The good news is that the SSL tunneling bug is fixed so you can just use the default factory. I just tried with a proxy and everything works as expected. See my code,

public class SSLContextTest {

    public static void main(String[] args) {

        System.setProperty("https.proxyHost", "proxy.xxx.com");
        System.setProperty("https.proxyPort", "8888");

        try {

            SSLContext sslContext = SSLContext.getInstance("SSL");

            // set up a TrustManager that trusts everything
            sslContext.init(null, new TrustManager[] { new X509TrustManager() {
                public X509Certificate[] getAcceptedIssuers() {
                    System.out.println("getAcceptedIssuers =============");
                    return null;
                }

                public void checkClientTrusted(X509Certificate[] certs,
                        String authType) {
                    System.out.println("checkClientTrusted =============");
                }

                public void checkServerTrusted(X509Certificate[] certs,
                        String authType) {
                    System.out.println("checkServerTrusted =============");
                }
            } }, new SecureRandom());

            HttpsURLConnection.setDefaultSSLSocketFactory(
                    sslContext.getSocketFactory());

            HttpsURLConnection
                    .setDefaultHostnameVerifier(new HostnameVerifier() {
                        public boolean verify(String arg0, SSLSession arg1) {
                            System.out.println("hostnameVerifier =============");
                            return true;
                        }
                    });

            URL url = new URL("https://www.verisign.net");
            URLConnection conn = url.openConnection();
            BufferedReader reader = 
                new BufferedReader(new InputStreamReader(conn.getInputStream()));
            String line;
            while ((line = reader.readLine()) != null) {
                System.out.println(line);
            }
        } catch (Exception e) {
            e.printStackTrace();
        } 
    }
}

This is what I get when I run the program,

checkServerTrusted =============
hostnameVerifier =============
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.1//EN" "http://www.w3.org/TR/xhtml11/DTD/xhtml11.dtd">
......

As you can see, both SSLContext and hostnameVerifier are getting called. HostnameVerifier is only involved when the hostname doesn't match the cert. I used "www.verisign.net" to trigger this.

In your example propertyInfo.GetValue(this, null) should work. Consider altering GetNamesAndTypesAndValues() as follows:

public void GetNamesAndTypesAndValues()
{
  foreach (PropertyInfo propertyInfo in allClassProperties)
  {
    Console.WriteLine("{0} [type = {1}] [value = {2}]",
      propertyInfo.Name,
      propertyInfo.PropertyType,
      propertyInfo.GetValue(this, null));
  }
}

To all:

Note that both of these example are NOT extension methods like the example above.

Lastly... apologies for my extensive/excessive comments (I had a anal/mean prof that beat it into me! ;)

Marc's answer is the approach I use for this, but for simplicity (and a friendlier API?) you can define a property in the collection base class if you have one such as:

public abstract class CollectionBase<T> : IList<T>
{
   ...

   public Type ElementType
   {
      get
      {
         return typeof(T);
      }
   }
}

I have found this approach useful, and is easy to understand for any newcomers to generics.

I think you're looking for a method like this:

public static IEnumerable<TResult> CompareSequences<T1, T2, TResult>(IEnumerable<T1> seq1,
    IEnumerable<T2> seq2, Func<T1, T2, TResult> comparer)
{
    var enum1 = seq1.GetEnumerator();
    var enum2 = seq2.GetEnumerator();

    while (enum1.MoveNext() && enum2.MoveNext())
    {
        yield return comparer(enum1.Current, enum2.Current);
    }
}

It's untested, but it should do the job nonetheless. Note that what's particularly useful about this method is that it's full generic, i.e. it can take two sequences of arbitrary (and different) types and return objects of any type.

This solution of course assumes that you want to compare the nth item of seq1 with the nth item in seq2. If you want to do match the elements in the two sequences based on a particular property/comparison, then you'll want to perform some sort of join operation (as suggested by danbruc using Enumerable.Join. Do let me know if it neither of these approaches is quite what I'm after and maybe I can suggest something else.

Edit: Here's an example of how you might use the CompareSequences method with the comparer function you originally posted.

// Prints out to the console all the results returned by the comparer function (CompareTwoClass_ReturnDifferences in this case).
var results = CompareSequences(list1, list2, CompareTwoClass_ReturnDifferences);
int index;    

foreach(var element in results)
{
    Console.WriteLine("{0:#000} {1}", index++, element.ToString());
}

my solution inspired from Aras Alenin answer above where I added one level of object comparison and a custom object for comparison results. I am also interested to get property name with object name:

    public static IEnumerable<ObjectPropertyChanged> GetPublicSimplePropertiesChanged<T>(this T previous, T proposedChange,
     string[] namesOfPropertiesToBeIgnored) where T : class
    {
        return GetPublicGenericPropertiesChanged(previous, proposedChange, namesOfPropertiesToBeIgnored, true, null, null);
    }

    public static IReadOnlyList<ObjectPropertyChanged> GetPublicGenericPropertiesChanged<T>(this T previous, T proposedChange,
        string[] namesOfPropertiesToBeIgnored) where T : class
    {
        return GetPublicGenericPropertiesChanged(previous, proposedChange, namesOfPropertiesToBeIgnored, false, null, null);
    }

    /// <summary>
    /// Gets the names of the public properties which values differs between first and second objects.
    /// Considers 'simple' properties AND for complex properties without index, get the simple properties of the children objects.
    /// </summary>
    /// <typeparam name="T"></typeparam>
    /// <param name="previous">The previous object.</param>
    /// <param name="proposedChange">The second object which should be the new one.</param>
    /// <param name="namesOfPropertiesToBeIgnored">The names of the properties to be ignored.</param>
    /// <param name="simpleTypeOnly">if set to <c>true</c> consider simple types only.</param>
    /// <param name="parentTypeString">The parent type string. Meant only for recursive call with simpleTypeOnly set to <c>true</c>.</param>
    /// <param name="secondType">when calling recursively, the current type of T must be clearly defined here, as T will be more generic (using base class).</param>
    /// <returns>
    /// the names of the properties
    /// </returns>
    private static IReadOnlyList<ObjectPropertyChanged> GetPublicGenericPropertiesChanged<T>(this T previous, T proposedChange,
        string[] namesOfPropertiesToBeIgnored, bool simpleTypeOnly, string parentTypeString, Type secondType) where T : class
    {
        List<ObjectPropertyChanged> propertiesChanged = new List<ObjectPropertyChanged>();

        if (previous != null && proposedChange != null)
        {
            var type = secondType == null ? typeof(T) : secondType;
            string typeStr = parentTypeString + type.Name + ".";
            var ignoreList = namesOfPropertiesToBeIgnored.CreateList();
            IEnumerable<IEnumerable<ObjectPropertyChanged>> genericPropertiesChanged =
                from pi in type.GetProperties(BindingFlags.Public | BindingFlags.Instance)
                where !ignoreList.Contains(pi.Name) && pi.GetIndexParameters().Length == 0 
                    && (!simpleTypeOnly || simpleTypeOnly && pi.PropertyType.IsSimpleType())
                let firstValue = type.GetProperty(pi.Name).GetValue(previous, null)
                let secondValue = type.GetProperty(pi.Name).GetValue(proposedChange, null)
                where firstValue != secondValue && (firstValue == null || !firstValue.Equals(secondValue))
                let subPropertiesChanged = simpleTypeOnly || pi.PropertyType.IsSimpleType()
                    ? null
                    : GetPublicGenericPropertiesChanged(firstValue, secondValue, namesOfPropertiesToBeIgnored, true, typeStr, pi.PropertyType)
                let objectPropertiesChanged = subPropertiesChanged != null && subPropertiesChanged.Count() > 0
                    ? subPropertiesChanged
                    : (new ObjectPropertyChanged(proposedChange.ToString(), typeStr + pi.Name, firstValue.ToStringOrNull(), secondValue.ToStringOrNull())).CreateList()
                select objectPropertiesChanged;

            if (genericPropertiesChanged != null)
            {   // get items from sub lists
                genericPropertiesChanged.ForEach(a => propertiesChanged.AddRange(a));
            }
        }
        return propertiesChanged;
    }

Using the following class to store comparison results

[System.Serializable]
public class ObjectPropertyChanged
{
    public ObjectPropertyChanged(string objectId, string propertyName, string previousValue, string changedValue)
    {
        ObjectId = objectId;
        PropertyName = propertyName;
        PreviousValue = previousValue;
        ProposedChangedValue = changedValue;
    }

    public string ObjectId { get; set; }

    public string PropertyName { get; set; }

    public string PreviousValue { get; set; }

    public string ProposedChangedValue { get; set; }
}

And a sample unit test:

    [TestMethod()]
    public void GetPublicGenericPropertiesChangedTest1()
    {
        // Define objects to test
        Function func1 = new Function { Id = 1, Description = "func1" };
        Function func2 = new Function { Id = 2, Description = "func2" };
        FunctionAssignment funcAss1 = new FunctionAssignment
        {
            Function = func1,
            Level = 1
        };
        FunctionAssignment funcAss2 = new FunctionAssignment
        {
            Function = func2,
            Level = 2
        };

        // Main test: read properties changed
        var propertiesChanged = Utils.GetPublicGenericPropertiesChanged(funcAss1, funcAss2, null);

        Assert.IsNotNull(propertiesChanged);
        Assert.IsTrue(propertiesChanged.Count == 3);
        Assert.IsTrue(propertiesChanged[0].PropertyName == "FunctionAssignment.Function.Description");
        Assert.IsTrue(propertiesChanged[1].PropertyName == "FunctionAssignment.Function.Id");
        Assert.IsTrue(propertiesChanged[2].PropertyName == "FunctionAssignment.Level");
    }

Guzzle implements PSR-7. That means that it will by default store the body of a message in a Stream that uses PHP temp streams. To retrieve all the data, you can use casting operator:

$contents = (string) $response->getBody();

You can also do it with

$contents = $response->getBody()->getContents();

The difference between the two approaches is that getContents returns the remaining contents, so that a second call returns nothing unless you seek the position of the stream with rewind or seek .

$stream = $response->getBody();
$contents = $stream->getContents(); // returns all the contents
$contents = $stream->getContents(); // empty string
$stream->rewind(); // Seek to the beginning
$contents = $stream->getContents(); // returns all the contents

Instead, usings PHP's string casting operations, it will reads all the data from the stream from the beginning until the end is reached.

$contents = (string) $response->getBody(); // returns all the contents
$contents = (string) $response->getBody(); // returns all the contents

This seems to work: /(\{(?:\{.*\}|[^\{])*\})/m

Another solution would be to pass the textbox (or control you want to modify) into the method that will manipulate it as a parameter.

public partial class Form1 : Form
{
    public Form1()
    {
        InitializeComponent();
    }

    private void button1_Click(object sender, EventArgs e)
    {
        TestClass test = new TestClass();
        test.ModifyText(textBox1);
    }
}

public class TestClass
{
    public void ModifyText(TextBox textBox)
    {
        textBox.Text = "New text";
    }
}

I had the same problem.

In addition to @enyo's answer in checking for files that are still uploading or in the queue, I also created a new function in dropzone.js to check for any files in an ERROR state (ie bad file type, size, etc).

Dropzone.prototype.getErroredFiles = function () {
    var file, _i, _len, _ref, _results;
    _ref = this.files;
    _results = [];
    for (_i = 0, _len = _ref.length; _i < _len; _i++) {
        file = _ref[_i];
        if (file.status === Dropzone.ERROR) {
            _results.push(file);
        }
    }
    return _results;
};

And thus, the check would become:

  if (this.getUploadingFiles().length === 0 && this.getQueuedFiles().length === 0 && this.getErroredFiles().length === 0) {
    doSomething();
  }

First you need to create the config file, using cmd : jupyter notebook --generate-config Then, search for C:\Users\your_username\.jupyter folder (Search for that folder), and right click edit the jupyter_notebook_config.py.

Then, Ctrl+F: #c.NotebookApp.notebook_dir ='' . Note that the quotes are single quotes. Select your directory you want to have as home for your jupyter, and copy it with Ctrl+C, for example: C:\Users\username\Python Projects.

Then on that line, paste it like this : c.NotebookApp.notebook_dir = 'C:\\Users\\username\\Python Projects'

Make sure to remove #, as it is as comment.

Make sure to double slash \\ on each name of your path. Ctrl+S to save the config.py file !!!

Go back to your cmd and run jupyter notebook. It should be in your directory of choice. Test it by making a folder and watch your directory from your computer.

Here is my solution. It works with positive and negative numbers. Hope this helps

function findDigitAmount(num) {

   var positiveNumber = Math.sign(num) * num;
   var lengthNumber = positiveNumber.toString();

 return lengthNumber.length;
}


(findDigitAmount(-96456431);    // 8
(findDigitAmount(1524):         // 4

My Code Is Very Easy To Understand

var year = 2015;
var LeapYear = year % 4;

if (LeapYear==0) {
    alert("This is Leap Year");
} else {
    alert("This is not leap year");
}

It depends on what concrete List class you are using. The abstract class AbstractCollection has a method called containsAll(Collection) that takes another collection ( a List is a collection) and:

Returns true if this collection contains all of the elements in the specified collection.

So if an ArrayList is being passed in you can call this method to see if they are exactly the same.

       List foo = new ArrayList();
    List bar = new ArrayList();
    String str = "foobar";

    foo.add(str);
    bar.add(str);

    foo.containsAll(bar);

The reason for containsAll() is because it iterates through the first list looking for the match in the second list. So if they are out of order equals() will not pick it up.

EDIT: I just want to make a comment here about the amortized running time of performing the various options being offered. Is running time important? Sure. Is it the only thing you should consider? No.

The cost of copying EVERY single element from your lists into other lists takes time, and it also takes up a good chunk of memory (effectively doubling the memory you are using).

So if memory in your JVM isn't a concern (which it should generally be) then you still need to consider the time it takes to copy every element from two lists into two TreeSets. Remember it is sorting every element as it enters them.

My final advice? You need to consider your data set and how many elements you have in your data set, and also how large each object in your data set is before you can make a good decision here. Play around with them, create one each way and see which one runs faster. It's a good exercise.

You would get a type mismatch if Sheets(name).Cells(4 + i, 57) contains a non-numeric value. You should validate the fields before you assume they are numbers and try to subtract from them.

Also, you should enable Option Strict so you are forced to explicitly convert your variables before trying to perform type-dependent operations on them such as subtraction. That will help you identify and eliminate issues in the future, too.    Unfortunately Option Strict is for VB.NET only. Still, you should look up best practices for explicit data type conversions in VBA.

Update:

If you are trying to go for the quick fix of your code, however, wrap the ** line and the one following it in the following condition:

If IsNumeric(Sheets(name).Cells(4 + i, 57))
    Sheets(name).Cells(4 + i, 58) = Sheets(name).Cells(4 + i, 57) - a
    x = Sheets(name).Cells(4 + i, 57) - a
End If

Note that your x value may not contain its expected value in the next iteration, however.

1. List out all available dbs show dbs
2. Choose the necessary db use
3. Drop the database db.dropDatabase() //Few additional commands
4. List all collections available in a db show collections
5. Remove a specification collection db.collection.drop()

Hope that helps

[^0-9][+-]?[0-9]{1,10}[^0-9]

In words: Optional + or - followed by a digit, repeated one up to ten times. Note that most libraries have a shortcut for a digit: \d, hence the above could also be written as: \d{1,10}.

I think I figured out the problem, this input field is part of a reactive form (?), since you have included formControlName. This means that what you are trying to do by disabling the input field with is_edit is not working, e.g your attempt [disabled]="is_edit", which would in other cases work. With your form you need to do something like this:

toggle() {
  let control = this.myForm.get('name')
  control.disabled ? control.enable() : control.disable();
}

and lose the is_edit altogether.

if you want the input field to be disabled as default, you need to set the form control as:

name: [{value: '', disabled:true}]

Here's a plunker

Second Thomas David Kehoe, with the following caveat --

If you are using node version manager (nvm), your global node modules will be stored under whatever version of node you are using at the time you saved the module.

So ~/.nvm/versions/node/{version}/lib/node_modules/.

It turns out this is actually possible, but not using the genuine Docker CE or EE version.

You can either use Red Hat's fork of docker with the '--add-registry' flag or you can build docker from source yourself with registry/config.go modified to use your own hard-coded default registry namespace/index.

Here are two methods to achieve the same thing:

Using parameters and return (recommended)

def other_function(parameter):
    return parameter + 5

def main_function():
    x = 10
    print(x)    
    x = other_function(x)
    print(x)

When you run main_function, you'll get the following output

>>> 10
>>> 15

Using globals (never do this)

x = 0   # The initial value of x, with global scope

def other_function():
    global x
    x = x + 5

def main_function():
    print(x)    # Just printing - no need to declare global yet
    global x   # So we can change the global x
    x = 10
    print(x)
    other_function()
    print(x)

Now you will get:

>>> 0    # Initial global value
>>> 10   # Now we've set it to 10 in `main_function()`
>>> 15   # Now we've added 5 in `other_function()`

You could also use the whitelist method -

var str = $('#Search').val();
var regex = /[^\w\s]/gi;

if(regex.test(str) == true) {
    alert('Your search string contains illegal characters.');
}

The regex in this example is digits, word characters, underscores (\w) and whitespace (\s). The caret (^) indicates that we are to look for everything that is not in our regex, so look for things that are not word characters, underscores, digits and whitespace.

You are looking for a Sublime UI Theme, which modifies Sublime's User Interface (e.g.: side bar). It's different from a Color Theme/Scheme, which modifies only the code part of Sublime's window. I tested a lot of UI Themes and the one I liked the most was Theme - Soda. You can install it using Sublime's Package Control. To enable it, go to Preferences >> Settings - User and add this line:

"theme": "Soda Dark 3.sublime-theme",

Here is a printscreen of my Sublime Text 3 with Soda Dark UI Theme and Twilight default Color Scheme:

If you have multiple elements in the clickable div, you should do this:

$('#clickable *').click(function(e){ e.stopPropagation(); });

To make it work with both text and numbers:

Exact match:

=query(D:E,"select * where D like '"&C1&"'", 0)

Convert search string to lowercase:

=query(D:E,"select * where D like lower('"&C1&"')", 0)

Convert to lowercase and contain part of the search string:

=query(D:E,"select * where D like lower('%"&C1&"%')", 0)

A1                = query/formula
yellow / A:B  = result area
green / C1    = search area
blue / D:E     = data area

If you get error when the input is text and not numbers; move the data and delete the (now empty) columns. Then move the data back.

Try this instead:

sumall = summ + sumd + sumy
print "The sum of your numbers is", sumall
sumall = str(sumall) # add this line
sumln = (int(sumall[0])+int(sumall[1]))
print "Your lucky number is", sumln

sumall is a number, and you can't access its digits using the subscript notation (sumall[0], sumall[1]). For that to work, you'll need to transform it back to a string.

Two years late, but I have the solution you're looking for. Not intending to take credit form the original author, here's a plugin which I found works exceptionally well for what you need, but gets all possible styles in all browsers, even IE.

Warning: This code generates a lot of output, and should be used sparingly. It not only copies all standard CSS properties, but also all vendor CSS properties for that browser.

jquery.getStyleObject.js:

/*
 * getStyleObject Plugin for jQuery JavaScript Library
 * From: http://upshots.org/?p=112
 */

(function($){
    $.fn.getStyleObject = function(){
        var dom = this.get(0);
        var style;
        var returns = {};
        if(window.getComputedStyle){
            var camelize = function(a,b){
                return b.toUpperCase();
            };
            style = window.getComputedStyle(dom, null);
            for(var i = 0, l = style.length; i < l; i++){
                var prop = style[i];
                var camel = prop.replace(/\-([a-z])/g, camelize);
                var val = style.getPropertyValue(prop);
                returns[camel] = val;
            };
            return returns;
        };
        if(style = dom.currentStyle){
            for(var prop in style){
                returns[prop] = style[prop];
            };
            return returns;
        };
        return this.css();
    }
})(jQuery);

Basic usage is pretty simple, but he's written a function for that as well:

$.fn.copyCSS = function(source){
  var styles = $(source).getStyleObject();
  this.css(styles);
}

Hope that helps.

select CAST(COUNT(*) AS BIT) FROM [User] WHERE (UserID = 20070022)

If count(*) = 0 returns false. If count(*) > 0 returns true.

The runas command does not allow a password on its command line. This is by design (and also the reason you cannot pipe a password to it as input). Raymond Chen says it nicely:

The RunAs program demands that you type the password manually. Why doesn't it accept a password on the command line?

This was a conscious decision. If it were possible to pass the password on the command line, people would start embedding passwords into batch files and logon scripts, which is laughably insecure.

In other words, the feature is missing to remove the temptation to use the feature insecurely.

Bit of a late response but I noticed that this information can be hard to find and haven't found the answer on SO, so here it is.

Try a differnt parameter #view=FitH to force it to fit in the horzontal space and also you need to start the querystring off with a # rather than an & making it:

filename.pdf#view=FitH

What I've noticed it is that this will work if adobe reader is embedded in the browser but chrome will use it's own version of the reader and won't respond in the same way. In my own case, the chrome browser zoomed to fit width by default, so no problem , but Internet Explorer needed the above parameters to ensure the link always opened the pdf page with the correct view setting.

For a full list of available parameters see this doc

EDIT: (lazy mode on)

Very simple use of any

df <- <your structure>

df$Den <- apply(df,1,function(i) {ifelse(any(is.na(i)) | any(i != 1), 0, 1)})

Does your page contain these

<asp:Content ID="Content1" ContentPlaceHolderID="ContentPlaceHolder1"
Runat="Server">
</asp:content>

tags, and are all your controls inside these? You should only have the Form tags in the MasterPage.

Here are some of my understanding and suggestion:

Html element can be put in the body of html pages and html page does support multiple elements, however they can not be nested each other, you can find the detailed description from the W3C html specification:

The FORM element

http://www.w3.org/MarkUp/html3/forms.html

And as for ASP.NET web form page, it is based on a single server-side form element which contains all the controls inside it, so generally we do not recommend that we put multiple elements. However, this is still supported in ASP.NET page(master page) and I think the problem in your master page should be caused by the unsupported nested element, and multiple in the same level should be ok. e.g:

In addition, if what you want to do through multiple forms is just make our page posting to multiple pages, I think you can consider using the new feature for cross-page posting in ASP.NET 2.0. This can help us use button controls to postback to different pages without having multpile forms on the page:

Cross-Page Posting in ASP.NET Web Pages

You may have as many levels of Object hierarchy as you want, as long you declare an Object as being a property of another parent Object. Pay attention to the commas on each level, that's the tricky part. Don't use commas after the last element on each level:

{el1, el2, {el31, el32, el33}, {el41, el42}}

var MainObj = {_x000D_
_x000D_
  prop1: "prop1MainObj",_x000D_
  _x000D_
  Obj1: {_x000D_
    prop1: "prop1Obj1",_x000D_
    prop2: "prop2Obj1",    _x000D_
    Obj2: {_x000D_
      prop1: "hey you",_x000D_
      prop2: "prop2Obj2"_x000D_
    }_x000D_
  },_x000D_
    _x000D_
  Obj3: {_x000D_
    prop1: "prop1Obj3",_x000D_
    prop2: "prop2Obj3"_x000D_
  },_x000D_
  _x000D_
  Obj4: {_x000D_
    prop1: true,_x000D_
    prop2: 3_x000D_

_x000D_
console.log(MainObj.Obj1.Obj2.prop1);

I was missing several DLLs. Even if I manually copied them to the directory the next time I published they would disappear. Each one was already set to Copy Locally in VS. The fix for me was to set each one to Copy Locally false, save, build then set each one to copy locally true. This time when I published all of the DLLs published correctly. Strange

In case you work with Oracle, this way would be preferable:

create table my_users(id number, name varchar2(100), email varchar2(100));

insert into my_users values (1, 'John', '[email protected]');
insert into my_users values (2, 'Sam', '[email protected]');
insert into my_users values (3, 'Tom', '[email protected]');
insert into my_users values (4, 'Bob', '[email protected]');
insert into my_users values (5, 'Tom', '[email protected]');

commit;

select *
  from my_users
 where rowid not in (select min(rowid) from my_users group by name, email);

<script type="text/javascript">
window.setTimeout("location=('timeout_session.htm');",900000);
</script>

In the header of every page has been working for me during site tests(the site is not yet in production). The HTML page it falls to ends the session and just informs the user of the need to log in again. This seems an easier way than playing with PHP logic. I'd love some comments on the idea. Any traps I havent seen in it ?

Something like this will do it:

Rows("12:12").Select
Selection.Delete

So in your code it would look like something like this:

Rows(CStr(rand) & ":" & CStr(rand)).Select
Selection.Delete

If you want to include both simpler than what I saw here, you can do it just by including your button inside form.

Example with a function sending a message:

                <form>
                    <mat-form-field> <!-- In my case I'm using material design -->
                        <input matInput #message maxlength="256" placeholder="Message">
                    </mat-form-field>
                    <button (click)="addMessage(message.value)">Send message
                    </button>
                </form>

You can choose between clicking on the button or pressing enter key.

There are many solutions to this problem but for my situation, I just needed to correct the DATE on the machine/server (Ubuntu 16.04 Server).

i) Check the date of your server and correct it.

ii) Run sudo /etc/init.d/mysql restart

That should get it started.

if (myList?.Any() == true) 
{
   ...
}

I find this the most convenient way. '== true' checks the value of the nullable bool implied by '?.Any()

curl's --data will by default send Content-Type: application/x-www-form-urlencoded in the request header. However, when using Postman's raw body mode, Postman sends Content-Type: text/plain in the request header.

So to achieve the same thing as Postman, specify -H "Content-Type: text/plain" for curl:

curl -X POST -H "Content-Type: text/plain" --data "this is raw data" http://78.41.xx.xx:7778/

Note that if you want to watch the full request sent by Postman, you can enable debugging for packed app. Check this link for all instructions. Then you can inspect the app (right-click in Postman) and view all requests sent from Postman in the network tab :

In the case you need to do some asynchronous code (like sending a message to the server that the user is not focused on your page right now), the event beforeunload will not give time to the async code to run. In the case of async I found that the visibilitychange and mouseleave events are the best options. These events fire when the user change tab, or hiding the browser, or taking the courser out of the window scope.

document.addEventListener('mouseleave', e=>{_x000D_
     //do some async code_x000D_
})_x000D_
_x000D_
document.addEventListener('visibilitychange', e=>{_x000D_
     if (document.visibilityState === 'visible') {_x000D_
   //report that user is in focus_x000D_
    } else {_x000D_
     //report that user is out of focus_x000D_
    }  _x000D_
})

The equivalent command in svn is:

svn log --diff -r revision

Honestly I don't see the point in doing superscript/subscript in CSS only. There's no handy CSS attribute for it, just a bunch of homegrown implementations including:

.superscript { position: relative; top: -0.5em; font-size: 80%; }

or using vertical-align or I'm sure other ways. Thing is, it starts to get complicated:

• CSS superscript spacing on line height;
• Beware CSS for Superscript/Subcript on why you arguably shouldn't style superscript/subscript with CSS at all;

The second point is worth emphasizing. Typically superscript/subscript is not actually a styling issue but is indicative of meaning.

Side note: It's worth mentioning this list of entities for common mathematical superscript and subscript expressions even though this question doesn't relate to that.

The sub/sup tags are in HTML and XHTML. I would just use those.

As for the rest of your CSS, the :after pseudo-element and content attributes are not widely supported. If you really don't want to put this manually in the HTML I think a Javascript-based solution is your next best bet. With jQuery this is as simple as:

$(function() {
  $("a.external").append("<sup>+</sup>");
};

To perform *new tile_tree_apple the constructor of tile_tree_apple should be called, but in this place compiler knows nothing about tile_tree_apple, so it can't use the constructor.

If you put

tile tile_tree::tick() {if (rand()%20==0) return *new tile_tree_apple;};

in separate cpp file which has the definition of class tile_tree_apple or includes the header file which has the definition everything will work fine.

You could extend the "string" class to let you return a limited string.

using System;

namespace ConsoleApplication1
{
   class Program
   {
      static void Main(string[] args)
      {
         // since specified strings are treated on the fly as string objects...
         string limit5 = "The quick brown fox jumped over the lazy dog.".LimitLength(5);
         string limit10 = "The quick brown fox jumped over the lazy dog.".LimitLength(10);
         // this line should return us the entire contents of the test string
         string limit100 = "The quick brown fox jumped over the lazy dog.".LimitLength(100);

         Console.WriteLine("limit5   - {0}", limit5);
         Console.WriteLine("limit10  - {0}", limit10);
         Console.WriteLine("limit100 - {0}", limit100);

         Console.ReadLine();
      }
   }

   public static class StringExtensions
   {
      /// <summary>
      /// Method that limits the length of text to a defined length.
      /// </summary>
      /// <param name="source">The source text.</param>
      /// <param name="maxLength">The maximum limit of the string to return.</param>
      public static string LimitLength(this string source, int maxLength)
      {
         if (source.Length <= maxLength)
         {
            return source;
         }

         return source.Substring(0, maxLength);
      }
   }
}

Result:

limit5 - The q
limit10 - The quick
limit100 - The quick brown fox jumped over the lazy dog.

I do this as a side-effect of pushing with the -u option as in

$ git push -u origin branch-name

The equivalent long option is --set-upstream.

The git-branch command also understands --set-upstream, but its use can be confusing. Version 1.8.0 modifies the interface.

git branch --set-upstream is deprecated and may be removed in a relatively distant future. git branch [-u|--set-upstream-to] has been introduced with a saner order of arguments.

…

It was tempting to say git branch --set-upstream origin/master, but that tells Git to arrange the local branch "origin/master" to integrate with the currently checked out branch, which is highly unlikely what the user meant. The option is deprecated; use the new --set-upstream-to (with a short-and-sweet -u) option instead.

Say you have a local foo branch and want it to treat the branch by the same name as its upstream. Make this happen with

$ git branch foo
$ git branch --set-upstream-to=origin/foo

or just

$ git branch --set-upstream-to=origin/foo foo

In Visual Studio 2015 this shortcut opens a preview of the definition which even works through typedefs and #defines.

How about the following one? Should allow you to use either raw_input or input in both Python2 and Python3 with the semantics of Python2's raw_input (aka the semantics of Python3's input)

# raw_input isn't defined in Python3.x, whereas input wasn't behaving like raw_input in Python 2.x
# this should make both input and raw_input work in Python 2.x/3.x like the raw_input from Python 2.x 
try: input = raw_input
except NameError: raw_input = input

Here is how I was able to trick Excel to count expired certifications in a list. I didn't have a set date, or date range, just current date. "TODAY()" doesn't work in these for Excel 2013. It sees it as text or condition, not the date value. So these previous didn't work for me. So the word problem/scenario: How many people are expired in this list?

Use: =IFERROR(D5-TODAY(),0) Where D5 is the date to be interrogated.

Then use: =IF(J5>=1,1,0) Where J5 is the cell where the first equation is producing either a positive or negative number. This set, I have hidden on the side of the visible sheet, then I just sum the total for the number of unexpired members.

There is Code Iris which you can install by going to File -> Settings -> Plugins -> Browse Repositories, then find and choose Code Iris. Restart then you will have a new Code Iris tab.

People run into this error when the Node.js process is still running and they are attempting to start the server again. Try this:

ps aux | grep node

This will print something along the lines of:

user    7668  4.3  1.0  42060 10708 pts/1    Sl+  20:36   0:00 node server
user    7749  0.0  0.0   4384   832 pts/8    S+   20:37   0:00 grep --color=auto node

In this case, the process will be the one with the pid 7668. To kill it and restart the server, run kill -9 7668.

Just to agree with everyone else: don't parse HTML using regexp.

It isn't possible to create an expression that will pick out attributes for even a correct piece of HTML, never mind all the possible malformed variants. Your regexp is already pretty much unreadable even without trying to cope with the invalid lack of quotes; chase further into the horror of real-world HTML and you will drive yourself crazy with an unmaintainable blob of unreliable expressions.

There are existing libraries to either read broken HTML, or correct it into valid XHTML which you can then easily devour with an XML parser. Use them.

use DataTable object instead:

 private void doMore(DataTable dt)
    {
    foreach(DataColumn dc in dt.Columns)
    {
    MessageBox.Show(dc.ColumnName);
    }
    }

If you are wanting to just copy the whole column, you can simplify the code a lot by doing something like this:

Sub CopyCol()

    Sheets("Sheet1").Columns(1).Copy

    Sheets("Sheet2").Columns(2).PasteSpecial xlPasteValues

End Sub

Or

Sub CopyCol()

    Sheets("Sheet1").Columns("A").Copy

    Sheets("Sheet2").Columns("B").PasteSpecial xlPasteValues

End Sub

Or if you want to keep the loop

Public Sub CopyrangeA()

    Dim firstrowDB As Long, lastrow As Long
    Dim arr1, arr2, i As Integer

    firstrowDB = 1
    arr1 = Array("BJ", "BK")
    arr2 = Array("A", "B")

    For i = LBound(arr1) To UBound(arr1)

        Sheets("Sheet1").Columns(arr1(i)).Copy

        Sheets("Sheet2").Columns(arr2(i)).PasteSpecial xlPasteValues

    Next
    Application.CutCopyMode = False

End Sub

Also known as Frozen Binaries but not the same as as the output of a true compiler- they run byte code through a virtual machine (PVM). Run the same as a compiled program just larger because the program is being compiled along with the PVM. Py2exe can freeze standalone programs that use the tkinter, PMW, wxPython, and PyGTK GUI libraties; programs that use the pygame game programming toolkit; win32com client programs; and more. The Stackless Python system is a standard CPython implementation variant that does not save state on the C language call stack. This makes Python more easy to port to small stack architectures, provides efficient multiprocessing options, and fosters novel programming structures such as coroutines. Other systems of study that are working on future development: Pyrex is working on the Cython system, the Parrot project, the PyPy is working on replacing the PVM altogether, and of course the founder of Python is working with Google to get Python to run 5 times faster than C with the Unladen Swallow project. In short, py2exe is the easiest and Cython is more efficient for now until these projects improve the Python Virtual Machine (PVM) for standalone files.

The other difference between divide and conquer and dynamic programming could be:

Divide and conquer:

1. Does more work on the sub-problems and hence has more time consumption.
2. In divide and conquer the sub-problems are independent of each other.

Dynamic programming:

1. Solves the sub-problems only once and then stores it in the table.
2. In dynamic programming the sub-problem are not independent.

@Carlo I really like your implementation of this, but I wanted to share my version and how to use it in my ViewModel

First implement ICommand

public class Command : ICommand
{
    public delegate void ICommandOnExecute();
    public delegate bool ICommandOnCanExecute();

    private ICommandOnExecute _execute;
    private ICommandOnCanExecute _canExecute;

    public Command(ICommandOnExecute onExecuteMethod, ICommandOnCanExecute onCanExecuteMethod = null)
    {
        _execute = onExecuteMethod;
        _canExecute = onCanExecuteMethod;
    }

    #region ICommand Members

    public event EventHandler CanExecuteChanged
    {
        add { CommandManager.RequerySuggested += value; }
        remove { CommandManager.RequerySuggested -= value; }
    }

    public bool CanExecute(object parameter)
    {
        return _canExecute?.Invoke() ?? true;
    }

    public void Execute(object parameter)
    {
        _execute?.Invoke();
    }

    #endregion
}

Notice I have removed the parameter from ICommandOnExecute and ICommandOnCanExecute and added a null to the constructor

Then to use in the ViewModel

public Command CommandToRun_WithCheck
{
    get
    {
        return new Command(() =>
        {
            // Code to run
        }, () =>
        {
            // Code to check to see if we can run 
            // Return true or false
        });
    }
}

public Command CommandToRun_NoCheck
{
    get
    {
        return new Command(() =>
        {
            // Code to run
        });
    }
}

I just find this way cleaner as I don't need to assign variables and then instantiate, it all done in one go.

You need to use double apostrophe instead of single in the "You''re", eg:

String text = java.text.MessageFormat.format("You''re about to delete {0} rows.", 5);
System.out.println(text);

It used to be possible to compile Matlab to C with older versions of Matlab. Check out other tools that Matlab comes with.

Newest Matlab code can be exported as a Java's jar or a .Net Dll, etc. You can then write an executable against that library - it will be obfuscated by the way. The users will have to install a freely available Matlab Runtime.

Like others mentioned, mcc / mcc.exe is what you want to convert matlab code to C code.

select just changes cardinality of the result table but project does change both degree of relation and cardinality.

Get your response via a regular http-request, using:

• Apache HttpComponents
• the built-in URLConnection con = new URL("http://example.com").openConnection();

The next step is parsing it. Take a look at this article for a choice of parser.

The only way to get the iOS dictation is to sign up yourself through Nuance: http://dragonmobile.nuancemobiledeveloper.com/ - it's expensive, because it's the best. Presumably, Apple's contract prevents them from exposing an API.

The built in iOS accessibility features allow immobilized users to access dictation (and other keyboard buttons) through tools like VoiceOver and Assistive Touch. It may not be worth reinventing this if your users might be familiar with these tools.

I wrap everything in one class. Just call these lines of code when your viewcontroller is loaded:

- (void)viewDidLoad {
    [super viewDidLoad];
    KeyboardInsetScrollView *injectView = [[KeyboardInsetScrollView alloc] init];
    [injectView injectToView:self.view withRootView:self.view];
}

Here is link of sample project:
https://github.com/caohuuloc/KeyboardInsetScrollView

You can do:

setContentPane(new JLabel(new ImageIcon("resources/taverna.jpg")));

At first line of the Jframe class constructor, that works fine for me

My problem was, that the SDK Tools updated it to the latest version, in my case it was 1.0.0-alpha9, but in my gradle dependency was set to

compile 'com.android.support.constraint:constraint-layout:1.0.0-alpha8' So, you can change your gradle build file to

compile 'com.android.support.constraint:constraint-layout:1.0.0-alpha9' Or you check "Show package details" in the SDK Tools Editor and install your needed version. See screenshow below. Image of SDK Tools

but if you have other ways to do it please share.

You can compare two arrays. If any of the values in the left array overlap the values in the right array, then it returns true. It's kind of hackish, but it works.

SELECT '{1}'   && '{1,2,3}'::int[];  -- true
SELECT '{1,4}' && '{1,2,3}'::int[];  -- true
SELECT '{4}'   && '{1,2,3}'::int[];  -- false

• In the first and second query, value 1 is in the right array
• Notice that the second query is true, even though the value 4 is not contained in the right array
• For the third query, no values in the left array (i.e., 4) are in the right array, so it returns false

I got it fixed by running "C:\Program Files\Android\android-sdk\AVD Manager.exe" and repairing my broken device.

Can you try this?

SELECT [Title], [Firstname], [Surname], [Company_name], [Interest] 
FROM [dbo].[EXTRANET_users] 
WHERE CAST(Submission_date AS DATE) = CAST(GETDATE() AS DATE)

T-SQL doesn't really have the "implied" casting like C# does - you need to explicitly use CAST (or CONVERT).

Also, use GETDATE() or CURRENT_TIMESTAMP to get the "now" date and time.

Update: since you're working against SQL Server 2000 - none of those approaches so far work. Try this instead:

SELECT [Title], [Firstname], [Surname], [Company_name], [Interest] 
FROM [dbo].[EXTRANET_users] 
WHERE DATEADD(dd, 0, DATEDIFF(dd, 0, submission_date)) = DATEADD(dd, 0, DATEDIFF(dd, 0, GETDATE()))

I got same problem and solved using a flag.

bool flag = false;
while(true) {
    switch(msg->state) {
    case MSGTYPE: // ... 
        break;
    // ... more stuff ...
    case DONE:
        flag = true; // **HERE, I want to break out of the loop itself**
    }
    if(flag) break;
}

Keep the json file in Assets (parallel to app dir) directory

Note that if you would have generated with ng new YourAppname- this assets directory exists same line with 'app' directory, and services should be child directory of app directory. May look like as below:

::app/services/myservice.ts

getOrderSummary(): Observable {
    // get users from api
    return this.http.get('assets/ordersummary.json')//, options)
        .map((response: Response) => {
            console.log("mock data" + response.json());
            return response.json();
        }
    )
    .catch(this.handleError);
} 

In a new ASP.Net 5 MVC project in a controller action you can still do this.Context and this.Context.Request It looks like on the Request there is no longer a Url property but the child properties (schema, host, etc) are all on the request object directly.

 public IActionResult About()
    {
        ViewBag.Message = "Your application description page.";
        var schema = this.Context.Request.Scheme;

        return View();
    }

Rather or not you want to use this.Context or inject the property is another conversation. Dependency Injection in ASP.NET vNext

That's because in C - integer on 32 bit machine doesn't mean that 32 bits are used for storing it, it may be 16 bits as well. It depends on the machine (implementation-dependent).

Use Collections.emptyList() if you want to make sure that the returned list is never modified.

This is what is returned on calling emptyList():

/**
 * The empty list (immutable). 
 */
public static final List EMPTY_LIST = new EmptyList();

For Excel 2010 it should be UTF-8. Instruction by MS :
http://msdn.microsoft.com/en-us/library/bb507946:

"The basic document structure of a SpreadsheetML document consists of the Sheets and Sheet elements, which reference the worksheets in the Workbook. A separate XML file is created for each Worksheet. For example, the SpreadsheetML for a workbook that has two worksheets name MySheet1 and MySheet2 is located in the Workbook.xml file and is shown in the following code example.

<?xml version="1.0" encoding="UTF-8" standalone="yes" ?> 
<workbook xmlns=http://schemas.openxmlformats.org/spreadsheetml/2006/main xmlns:r="http://schemas.openxmlformats.org/officeDocument/2006/relationships">
    <sheets>
        <sheet name="MySheet1" sheetId="1" r:id="rId1" /> 
        <sheet name="MySheet2" sheetId="2" r:id="rId2" /> 
    </sheets>
</workbook>

The worksheet XML files contain one or more block level elements such as SheetData. sheetData represents the cell table and contains one or more Row elements. A row contains one or more Cell elements. Each cell contains a CellValue element that represents the value of the cell. For example, the SpreadsheetML for the first worksheet in a workbook, that only has the value 100 in cell A1, is located in the Sheet1.xml file and is shown in the following code example.

<?xml version="1.0" encoding="UTF-8" ?> 
<worksheet xmlns="http://schemas.openxmlformats.org/spreadsheetml/2006/main">
    <sheetData>
        <row r="1">
            <c r="A1">
                <v>100</v> 
            </c>
        </row>
    </sheetData>
</worksheet>

Select Into functionality only works for PL/SQL Block, when you use Execute immediate , oracle interprets v_query_str as a SQL Query string so you can not use into .will get keyword missing Exception. in example 2 ,we are using begin end; so it became pl/sql block and its legal.

try this

mysql_query("
SELECT * FROM Drinks WHERE
    email='$Email'
    AND date='$Date_Today'
    OR date='$Date_Yesterday', '$Date_TwoDaysAgo', '$Date_ThreeDaysAgo', '$Date_FourDaysAgo', '$Date_FiveDaysAgo', '$Date_SixDaysAgo', '$Date_SevenDaysAgo'"     
   );

my be like this

 OR date='$Date_Yesterday' oR '$Date_TwoDaysAgo'.........

Referencing my comments on other answers. This is how I would work out the difference in days based on 24 hours and calender days. the days attribute works well for 24 hours and the function works best for calendar checks.

from datetime import timedelta, datetime

def cal_days_diff(a,b):

    A = a.replace(hour = 0, minute = 0, second = 0, microsecond = 0)
    B = b.replace(hour = 0, minute = 0, second = 0, microsecond = 0)
    return (A - B).days

if __name__ == '__main__':

    x = datetime(2013, 06, 18, 16, 00)
    y = datetime(2013, 06, 19, 2, 00)

    print (y - x).days          # 0
    print cal_days_diff(y, x)   # 1 

    z = datetime(2013, 06, 20, 2, 00)

    print (z - x).days          # 1
    print cal_days_diff(z, x)   # 2 

This regularly occurs when you change the extension on the JAR for ZIP, extract the zip content and make some modifications on files such as changing the MANIFEST.MF file which is a very common case, many times Eclipse doesn't generate the MANIFEST file as we want, or maybe we would like to modify the CLASS-PATH or the MAIN-CLASS values of it.

The problem occurs when you zip back the folder.

A valid Runnable/Executable JAR has the next structure:

myJAR (Main-Directory)
    |-META-INF (Mandatory)
             |-MANIFEST.MF (Mandatory Main-class: com.MainClass)
    |-com 
         |-MainClass.class (must to implement the main method, mandatory)
    |-properties files (optional)
    |-etc (optional)

If your JAR complies with these rules it will work doesn't matter if you build it manually by using a ZIP tool and then you changed the extension back to .jar

Once you're done try execute it on the command line using:

java -jar myJAR.jar 

When you use a zip tool to unpack, change files and zip again, normally the JAR structure changes to this structure which is incorrect, since another directory level is added on the top of the file system making it a corrupted file as is shown below:

**myJAR (Main-Directory)
    |-myJAR (creates another directory making the file corrupted)**
          |-META-INF (Mandatory)
                   |-MANIFEST.MF (Mandatory Main-class: com.MainClass)
          |-com 
              |-MainClass.class (must to implement the main method, mandatory)
          |-properties files (optional)
          |-etc (optional)

:)

I would like to mention that, I came across the same situation when I tried adding a library into my project. All of a sudden all switch statements started to show errors!

Now I tried to remove the library which I added, even then it did not work. how ever "when I cleaned the project" all the errors just went off !

Another thing to check is whether you have Windows Firewall enabled, since that might be blocking port 42424.

UPDATE: I have created a video on sending multipart/form-data requests to explain this better.

Actually, Postman can do this. Here is a screenshot

Make sure you check the comment from @maxkoryukov

Be careful with explicit Content-Type header. Better - do not set it's value, the Postman is smart enough to fill this header for you. BUT, if you want to set the Content-Type: multipart/form-data - do not forget about boundary field.

To get the current path from within the JSP file you can simply do one of the following:

<%= request.getContextPath() %>
<%= request.getRequestURI() %>
<%= request.getRequestURL() %>

var fav = [];
$.each($("input[name='name']:checked"), function(){            
    fav.push($(this).val());
});

It will give you the value separeted by commas

I created a nice wrapper to call JavaScript methods; it also shows JavaScript errors in log:

private void callJavaScript(String methodName, Object...params){
    StringBuilder stringBuilder = new StringBuilder();
    stringBuilder.append("javascript:try{");
    stringBuilder.append(methodName);
    stringBuilder.append("(");
    for (int i = 0; i < params.length; i++) {
        Object param = params[i];
        if(param instanceof String){
            stringBuilder.append("'");
            stringBuilder.append(param.toString().replace("'", "\\'"));
            stringBuilder.append("'");
        }
        if(i < params.length - 1){
            stringBuilder.append(",");
        }
    }
    stringBuilder.append(")}catch(error){Android.onError(error.message);}");
    webView.loadUrl(stringBuilder.toString());
}

You need to add this too:

private class WebViewInterface{

    @JavascriptInterface
    public void onError(String error){
        throw new Error(error);
    }
}

And add this interface to your webview:

webView.getSettings().setJavaScriptEnabled(true);
webView.addJavascriptInterface(new WebViewInterface(), "AndroidErrorReporter");

This question is very old, but I found myself studying for a Microsoft Certification, and in the study book it was suggested to use:

          Raise pywintypes.error() if we could not re-spawn

querySelector can be a complete CSS(3)-Selector with IDs and Classes and Pseudo-Classes together like this:

'#id.class:pseudo'

// or

'tag #id .class .class.class'

with getElementsByClassName you can just define a class

'class'

with getElementById you can just define an id

'id'

In addition to @StephaneDelcroix's answer, before using:

git clone [email protected]/my-project.git .

make sure that your current dir is empty by using

ls -a

Replace

dateTime.setText(app.getTotalDl());

With

dateTime.setText(""+app.getTotalDl());

comparing with json is pretty bad. try this package to compare nested arrays and get the difference.

Update: Node.Js >= 10

We can use the new fs.promises API

const fs = require('fs').promises;

(async() => {
    const stat = await fs.lstat('test.txt');
    console.log(stat.isFile());
})().catch(console.error)

Any Node.Js version

Here's how you would detect if a path is a file or a directory asynchronously, which is the recommended approach in node. using fs.lstat

const fs = require("fs");

let path = "/path/to/something";

fs.lstat(path, (err, stats) => {

    if(err)
        return console.log(err); //Handle error

    console.log(`Is file: ${stats.isFile()}`);
    console.log(`Is directory: ${stats.isDirectory()}`);
    console.log(`Is symbolic link: ${stats.isSymbolicLink()}`);
    console.log(`Is FIFO: ${stats.isFIFO()}`);
    console.log(`Is socket: ${stats.isSocket()}`);
    console.log(`Is character device: ${stats.isCharacterDevice()}`);
    console.log(`Is block device: ${stats.isBlockDevice()}`);
});

Note when using the synchronous API:

When using the synchronous form any exceptions are immediately thrown. You can use try/catch to handle exceptions or allow them to bubble up.

try{
     fs.lstatSync("/some/path").isDirectory()
}catch(e){
   // Handle error
   if(e.code == 'ENOENT'){
     //no such file or directory
     //do something
   }else {
     //do something else
   }
}

This is called type assertion in TypeScript, and since TypeScript 1.6, there are two ways to express this:

// Original syntax
var markerSymbolInfo = <MarkerSymbolInfo> symbolInfo;

// Newer additional syntax
var markerSymbolInfo = symbolInfo as MarkerSymbolInfo;

Both alternatives are functionally identical. The reason for introducing the as-syntax is that the original syntax conflicted with JSX, see the design discussion here.

If you are in a position to choose, just use the syntax that you feel more comfortable with. I personally prefer the as-syntax as it feels more fluent to read and write.

I can offer you a jquery solution

add this in your <head></head> tag

<script type="text/javascript" src="http://code.jquery.com/jquery-1.10.2.min.js"></script>

add this after </ul>

 <script> $('ul li:first').remove(); </script> 

To see all commands that are being executed by the script, add the -x flag to your shabang line, and execute the command normally:

#! /bin/bash -x

matchdir="/home/joao/robocup/runner_workdir/matches/testmatch/"

teamAComm="`pwd`/a.sh"
teamBComm="`pwd`/b.sh"
include="`pwd`/server_official.conf"
serverbin='/usr/local/bin/rcssserver'

cd $matchdir
$serverbin include="$include" server::team_l_start="${teamAComm}" server::team_r_start="${teamBComm}" CSVSaver::save='true' CSVSaver::filename='out.csv'

Then if you sometimes want to ignore the debug output, redirect stderr somewhere.

I was able to get rid of my scroll bar on the body of text by removing my max-height attribute of my class.

When a script is loaded, any parameters that are passed are automatically loaded into a special variables $args. You can reference that in your script without first declaring it.

As an example, create a file called test.ps1 and simply have the variable $args on a line by itself. Invoking the script like this, generates the following output:

PowerShell.exe -File test.ps1 a b c "Easy as one, two, three"
a
b
c
Easy as one, two, three

As a general recommendation, when invoking a script by calling PowerShell directly I would suggest using the -File option rather than implicitly invoking it with the & - it can make the command line a bit cleaner, particularly if you need to deal with nested quotes.

If after modal hide, faded background is remained and does not let you click any where you can forcefully remove those by using below piece of code.

First hide (all) your modal div elements.

$('.modal').modal('hide');

Secondly remove 'modal-open' class from body and '.modal-backdrop' at the end of the page.

$('body').removeClass('modal-open');
$('.modal-backdrop').remove();

sorry for late answer but may be my code may help u.

I placed 3 buttons on the winform surface. button1 & 2 will set different value and button3 will retrieve current value. so when run my code first add the reference System.configuration

and click on first button and then click on 3rd button to see what value has been set. next time again click on second & 3rd button to see again what value has been set after change.

so here is the code.

using System.Configuration;

 private void button1_Click(object sender, EventArgs e)
{
    Configuration config = ConfigurationManager.OpenExeConfiguration(Application.ExecutablePath);
    config.AppSettings.Settings.Remove("DBServerName");
    config.AppSettings.Settings.Add("DBServerName", "FirstAddedValue1");
    config.Save(ConfigurationSaveMode.Modified);
}

private void button2_Click(object sender, EventArgs e)
{
    Configuration config = ConfigurationManager.OpenExeConfiguration(Application.ExecutablePath);
    config.AppSettings.Settings.Remove("DBServerName");
    config.AppSettings.Settings.Add("DBServerName", "SecondAddedValue1");
    config.Save(ConfigurationSaveMode.Modified);
}

private void button3_Click(object sender, EventArgs e)
{
    Configuration config = ConfigurationManager.OpenExeConfiguration(Application.ExecutablePath);
          MessageBox.Show(config.AppSettings.Settings["DBServerName"].Value);
}

For loading weights, you need to have a model first. It must be:

existingModel.save_weights('weightsfile.h5')
existingModel.load_weights('weightsfile.h5')     

If you want to save and load the entire model (this includes the model's configuration, it's weights and the optimizer states for further training):

model.save_model('filename')
model = load_model('filename')

Here is what I got.

    $(".some-class").click(function(e) {

    var posx = 0;
    var posy = 0;

    posx = e.pageX;
    posy = e.pageY;

    alert(posx);
    alert(posy);
});

this worked for me.

2. run npm install
3. and then npm start

This bugged me for ages so here is my version as I didn't want an empty object, I wanted one with all the properties but reset to some default value. Kind of like a new instantiation of a class.

let object1 = {_x000D_
  a: 'somestring',_x000D_

You are looking to see if a single value is in an array. Use in_array.

However note that case is important, as are any leading or trailing spaces. Use var_dump to find out the length of the strings too, and see if they fit.

You can parse a string into an integer with int.parse(). For example:

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

Note that int.parse() accepts 0x prefixed strings. Otherwise the input is treated as base-10.

You can parse a string into a double with double.parse(). For example:

var myDouble = double.parse('123.45');
assert(myDouble is double);
print(myDouble); // 123.45

parse() will throw FormatException if it cannot parse the input.

New-style classes inherit from object, or from another new style class:

class SomeObject(object):
    pass

class SubObject(SomeObject):
    pass

Old-style classes don't:

class SomeObject:
    pass

This only applies to Python 2 - in Python 3 all the above will create new-style classes.

See 9. Classes (Python tutorial), NewClassVsClassicClass and What is the difference between old style and new style classes in Python? for details.

Based on zapl's answer, adding try() around Closeable's closes the streams automatically after use.

public static void unzip(File zipFile, File targetDirectory) {
    try (FileInputStream fis = new FileInputStream(zipFile)) {
        try (BufferedInputStream bis = new BufferedInputStream(fis)) {
            try (ZipInputStream zis = new ZipInputStream(bis)) {
                ZipEntry ze;
                int count;
                byte[] buffer = new byte[Constant.DefaultBufferSize];
                while ((ze = zis.getNextEntry()) != null) {
                    File file = new File(targetDirectory, ze.getName());
                    File dir = ze.isDirectory() ? file : file.getParentFile();
                    if (!dir.isDirectory() && !dir.mkdirs())
                        throw new FileNotFoundException("Failed to ensure directory: " + dir.getAbsolutePath());
                    if (ze.isDirectory())
                        continue;
                    try (FileOutputStream fout = new FileOutputStream(file)) {
                        while ((count = zis.read(buffer)) != -1)
                            fout.write(buffer, 0, count);
                    }
                }
            }
        }
    } catch (Exception ex) {
        //handle exception
    }
}

Using Constant.DefaultBufferSize (65536) gotten from C# .NET 4 Stream.CopyTo from Jon Skeet's answer here: https://stackoverflow.com/a/411605/1876355

I always just see posts using byte[1024] or byte[4096] buffer, never knew it can be much larger which improves performance and is still working perfectly normal.

Here is the Stream Source code: https://referencesource.microsoft.com/#mscorlib/system/io/stream.cs

//We pick a value that is the largest multiple of 4096 that is still smaller than the large object heap threshold (85K).
// The CopyTo/CopyToAsync buffer is short-lived and is likely to be collected at Gen0, and it offers a significant
// improvement in Copy performance.

private const int _DefaultCopyBufferSize = 81920;

However, I dialed it back to 65536 which is also a multiple of 4096 just to be safe.

I had a need to capture and compare old values to the new values entered into a complex scheduling spreadsheet. I needed a general solution which worked even when the user changed many rows at the same time. The solution implemented a CLASS and a COLLECTION of that class.

The class: oldValue

Private pVal As Variant
Private pAdr As String
Public Property Get Adr() As String
   Adr = pAdr
End Property
Public Property Let Adr(Value As String)
    pAdr = Value
End Property
Public Property Get Val() As Variant
   Val = pVal
End Property
Public Property Let Val(Value As Variant)
   pVal = Value
End Property

There are three sheets in which i track cells. Each sheet gets its own collection as a global variable in the module named ProjectPlan as follows:

Public prepColl As Collection
Public preColl As Collection
Public postColl As Collection
Public migrColl As Collection

The InitDictionaries SUB is called out of worksheet.open to establish the collections.

Sub InitDictionaries()
    Set prepColl = New Collection
    Set preColl = New Collection
    Set postColl = New Collection
    Set migrColl = New Collection
End Sub

There are three modules used to manage each collection of oldValue objects they are Add, Exists, and Value.

Public Sub Add(ByRef rColl As Collection, ByVal sAdr As String, ByVal sVal As Variant)
    Dim oval As oldValue
    Set oval = New oldValue
    oval.Adr = sAdr
    oval.Val = sVal
    rColl.Add oval, sAdr
End Sub

Public Function Exists(ByRef rColl As Collection, ByVal sAdr As String) As Boolean
   Dim oReq As oldValue
   On Error Resume Next
   Set oReq = rColl(sAdr)
   On Error GoTo 0

   If oReq Is Nothing Then
      Exists = False
   Else
      Exists = True
   End If
End Function
Public Function Value(ByRef rColl As Collection, ByVal sAdr) As Variant
   Dim oReq As oldValue
   If Exists(rColl, sAdr) Then
      Set oReq = rColl(sAdr)
      Value = oReq.Val
   Else
      Value = ""
   End If
End Function

The heavy lifting is done in the Worksheet_SelectionChange callback. One of the four is shown below. The only difference is the collection used in the ADD and EXIST calls.

Private Sub Worksheet_SelectionChange(ByVal Target As Range)
   Dim mode As Range
   Set mode = Worksheets("schedule").Range("PlanExecFlag")
   If mode.Value = 2 Then
      Dim c As Range
      For Each c In Target
          If Not ProjectPlan.Exists(prepColl, c.Address) Then
             Call ProjectPlan.Add(prepColl, c.Address, c.Value)
          End If
      Next c
   End If
End Sub

THe VALUE call is called out of code executed from the Worksheet_Change Callback for example. I need to assign the correct collection based on the sheet name:

   Dim rColl As Collection
   If sheetName = "Preparations" Then
       Set rColl = prepColl
   ElseIf sheetName = "Pre-Tasks" Then
       Set rColl = preColl
   ElseIf sheetName = "Migr-Tasks" Then
       Set rColl = migrColl
   ElseIf sheetName = "post-Tasks" Then
       Set rColl = postColl
   Else
   End If

and then i am free to compute compare the some current value to the original value.

If Exists(rColl, Cell.Offset(0, 0).Address) Then
   tsk_delay = Cell.Offset(0, 0).Value - Value(rColl, Cell.Offset(0, 0).Address)
Else
   tsk_delay = 0
End If

Mark

I prefer this solution, over the accepted answer by Michael Williamson, it catches changes to sources+inline files, then sources+headers, and finally sources only. Advantage here is that the whole library is not recompiled if only a a few changes are made. Not a huge consideration for a project with a couple of files, bur if you have 10 or a 100 sources, you will notice the difference.

COMMAND= gcc -Wall -Iinclude ...

%.o: %.cpp %.inl
    $(COMMAND)

%.o: %.cpp %.hpp
    $(COMMAND)

%.o: %.cpp
    $(COMMAND)

It is a function that will halt program execution if the value it has evaluated is false. Usually it is surrounded by a macro so that it is not compiled into the resultant binary when compiled with release settings.

It is designed to be used for testing the assumptions you have made. For example:

void strcpy(char* dest, char* src){
    //pointers shouldn't be null
    assert(dest!=null);
    assert(src!=null);

    //copy string
    while(*dest++ = *src++);
}

The ideal you want is that you can make an error in your program, like calling a function with invalid arguments, and you hit an assert before it segfaults (or fails to work as expected)

Effectively, the IN statement creates a series of OR statements... so

SELECT * FROM table WHERE column IN (1, 2, 3)

Is effectively

SELECT * FROM table WHERE column = 1 OR column = 2 OR column = 3

And sadly, that is the route you'll have to take with your LIKE statements

SELECT * FROM table
WHERE column LIKE 'Text%' OR column LIKE 'Hello%' OR column LIKE 'That%'

Run ps aux | grep nodejs, find the PID of the process you're looking for, then run kill starting with SIGTERM (kill -15 25239). If that doesn't work then use SIGKILL instead, replacing -15 with -9.

I know this is an old question, but I just searched for the same thing and probably there are many others searching for a quick, mobile solution. Here is what I finally come up with:

# We set production environment by default
SetEnv PROD_ENV 1

<IfDefine DEV_ENV>
  # If 'DEV_ENV' has been defined, then unset the PROD_ENV
  UnsetEnv PROD_ENV

  AuthType Basic
  AuthName "Protected Area"
  AuthUserFile /var/www/foo.local/.htpasswd
  Require valid-user
</IfDefine>

<IfDefine PROD_ENV>
  AuthType Basic
  AuthName "Protected Area"
  AuthUserFile /home/foo/public_html/.htpasswd
  Require valid-user
</IfDefine>

To force the download of a PDF file, instead of being handled by the browser's PDF plugin:

public ActionResult DownloadPDF()
{
    return File("~/Content/MyFile.pdf", "application/pdf", "MyRenamedFile.pdf");
}

If you want to let the browser handle by its default behavior (plugin or download), just send two parameters.

public ActionResult DownloadPDF()
{
    return File("~/Content/MyFile.pdf", "application/pdf");
}

You'll need to use the third parameter to specify a name for the file on the browser dialog.

UPDATE: Charlino is right, when passing the third parameter (download filename) Content-Disposition: attachment; gets added to the Http Response Header. My solution was to send application\force-download as the mime-type, but this generates a problem with the filename of the download so the third parameter is required to send a good filename, therefore eliminating the need to force a download.

In my case, it seems ng is not registered into my environment path. I have been using npm run command to run the ng commands. Be aware in order to pass arguments you need an extra -- as per the npm run specification.

Example:

npm run ng g c components/scheduling **--** --module=app

Or:

npm run ng g c components/scheduling **--** --skip-import

It's already been answered how to get offset in minutes as an integer, but in case anyone wants the local GMT offset as a string e.g. "+1130":

function pad(number, length){
    var str = "" + number
    while (str.length < length) {
        str = '0'+str
    }
    return str
}

var offset = new Date().getTimezoneOffset()
offset = ((offset<0? '+':'-')+ // Note the reversed sign!
          pad(parseInt(Math.abs(offset/60)), 2)+
          pad(Math.abs(offset%60), 2))

Working Solution 100% Swift 5.3

i have read all the answers and want to share the code and hierarchy of lines which i have used in all my applications to animate them correctly, Some solutions here are not working, you should check them on slower devices e.g iPhone 5 at this moment.

self.btnHeightConstraint.constant = 110
UIView.animate(withDuration: 0.27) { [weak self] in 
     self?.view.layoutIfNeeded()
}

Using Stream

private static void copyFileUsingStream(File source, File dest) throws IOException {
    InputStream is = null;
    OutputStream os = null;
    try {
        is = new FileInputStream(source);
        os = new FileOutputStream(dest);
        byte[] buffer = new byte[1024];
        int length;
        while ((length = is.read(buffer)) > 0) {
            os.write(buffer, 0, length);
        }
    } finally {
        is.close();
        os.close();
    }
}

Using Channel

private static void copyFileUsingChannel(File source, File dest) throws IOException {
    FileChannel sourceChannel = null;
    FileChannel destChannel = null;
    try {
        sourceChannel = new FileInputStream(source).getChannel();
        destChannel = new FileOutputStream(dest).getChannel();
        destChannel.transferFrom(sourceChannel, 0, sourceChannel.size());
       }finally{
           sourceChannel.close();
           destChannel.close();
       }
}

Using Apache Commons IO lib:

private static void copyFileUsingApacheCommonsIO(File source, File dest) throws IOException {
    FileUtils.copyFile(source, dest);
}

Using Java SE 7 Files class:

private static void copyFileUsingJava7Files(File source, File dest) throws IOException {
    Files.copy(source.toPath(), dest.toPath());
}

Or try Googles Guava :

Compare time:

    File source = new File("/Users/sidikov/tmp/source.avi");
    File dest = new File("/Users/sidikov/tmp/dest.avi");


    //copy file conventional way using Stream
    long start = System.nanoTime();
    copyFileUsingStream(source, dest);
    System.out.println("Time taken by Stream Copy = "+(System.nanoTime()-start));
     
    //copy files using java.nio FileChannel
    source = new File("/Users/sidikov/tmp/sourceChannel.avi");
    dest = new File("/Users/sidikov/tmp/destChannel.avi");
    start = System.nanoTime();
    copyFileUsingChannel(source, dest);
    System.out.println("Time taken by Channel Copy = "+(System.nanoTime()-start));
     
    //copy files using apache commons io
    source = new File("/Users/sidikov/tmp/sourceApache.avi");
    dest = new File("/Users/sidikov/tmp/destApache.avi");
    start = System.nanoTime();
    copyFileUsingApacheCommonsIO(source, dest);
    System.out.println("Time taken by Apache Commons IO Copy = "+(System.nanoTime()-start));
     
    //using Java 7 Files class
    source = new File("/Users/sidikov/tmp/sourceJava7.avi");
    dest = new File("/Users/sidikov/tmp/destJava7.avi");
    start = System.nanoTime();
    copyFileUsingJava7Files(source, dest);
    System.out.println("Time taken by Java7 Files Copy = "+(System.nanoTime()-start));

This worked for me:

1. Create a new project
2. Create a class in it
3. Add erroneous code, let error come
4. Now go to your project
5. Go to Problems window
6. Double click on a error

It starts showing compilation errors in the code.

Nope, there is no way to do this. What you might want to do is however to consider Polymorphism as a way to handle these kind of problems.

I would explain that way:

OneToOne - OneToOne relationship

@OneToOne
Person person;

@OneToOne
Nose nose;

OneToMany - ManyToOne relationship

@OneToMany
Shepherd> shepherd;

@ManyToOne
List<Sheep> sheeps;

ManyToMany - ManyToMany relationship

@ManyToMany
List<Traveler> travelers;

@ManyToMany
List<Destination> destinations;

Series is a one-dimensional labeled array capable of holding any data type (integers, strings, floating point numbers, Python objects, etc.). The axis labels are collectively referred to as the index. The basic method to create a Series is to call:

s = pd.Series(data, index=index)

DataFrame is a 2-dimensional labeled data structure with columns of potentially different types. You can think of it like a spreadsheet or SQL table, or a dict of Series objects.

 d = {'one' : pd.Series([1., 2., 3.], index=['a', 'b', 'c']),
 two' : pd.Series([1., 2., 3., 4.], index=['a', 'b', 'c', 'd'])}
 df = pd.DataFrame(d)

Look into distanceTo

Returns the approximate distance in meters between this location and the given location. Distance is defined using the WGS84 ellipsoid.

or distanceBetween

Computes the approximate distance in meters between two locations, and optionally the initial and final bearings of the shortest path between them. Distance and bearing are defined using the WGS84 ellipsoid.

You can create a Location object from a latitude and longitude:

Location locationA = new Location("point A");

locationA.setLatitude(latA);
locationA.setLongitude(lngA);

Location locationB = new Location("point B");

locationB.setLatitude(latB);
locationB.setLongitude(lngB);

float distance = locationA.distanceTo(locationB);

or

private double meterDistanceBetweenPoints(float lat_a, float lng_a, float lat_b, float lng_b) {
    float pk = (float) (180.f/Math.PI);

    float a1 = lat_a / pk;
    float a2 = lng_a / pk;
    float b1 = lat_b / pk;
    float b2 = lng_b / pk;

    double t1 = Math.cos(a1) * Math.cos(a2) * Math.cos(b1) * Math.cos(b2);
    double t2 = Math.cos(a1) * Math.sin(a2) * Math.cos(b1) * Math.sin(b2);
    double t3 = Math.sin(a1) * Math.sin(b1);
    double tt = Math.acos(t1 + t2 + t3);
   
    return 6366000 * tt;
}

The file name u used spring-dispatcher-servlet.xml
kindly check in web.xml
servlet name as spring-dispatcher at both tag  <servlet> and <servlet-mapping>
in your case it should be

<servlet>
<servlet-name>spring-dispatcher</servlet-name>
<servlet-class></servlet-class>
</servlet>
<servlet-mapping>
<servlet-name>spring-dispatcher</servlet-name>
<url-pattern></url-pattern>
</servlet-mapping>

In this line ...

if (*message == "\0") {

... as you can see in the warning ...

warning: comparison between pointer and integer
      ('int' and 'char *')

... you are actually comparing an int with a char *, or more specifically, an int with an address to a char.

To fix this, use one of the following:

if(*message == '\0') ...
if(message[0] == '\0') ...
if(!*message) ...

On a side note, if you'd like to compare strings you should use strcmp or strncmp, found in string.h.

So far, the accepted answer has worked best for me. However, my concern has always been that there is a likely scenario where I might refactor the notebooks directory into subdirectories, requiring to change the module_path in every notebook. I decided to add a python file within each notebook directory to import the required modules.

Thus, having the following project structure:

project
|__notebooks
   |__explore
      |__ notebook1.ipynb
      |__ notebook2.ipynb
      |__ project_path.py
   |__ explain
       |__notebook1.ipynb
       |__project_path.py
|__lib
   |__ __init__.py
   |__ module.py

I added the file project_path.py in each notebook subdirectory (notebooks/explore and notebooks/explain). This file contains the code for relative imports (from @metakermit):

import sys
import os

module_path = os.path.abspath(os.path.join(os.pardir, os.pardir))
if module_path not in sys.path:
    sys.path.append(module_path)

This way, I just need to do relative imports within the project_path.py file, and not in the notebooks. The notebooks files would then just need to import project_path before importing lib. For example in 0.0-notebook.ipynb:

import project_path
import lib

The caveat here is that reversing the imports would not work. THIS DOES NOT WORK:

import lib
import project_path

Thus care must be taken during imports.

In case you're already using the transform property for positioning your element (as I currently am), you can also animate the top margin:

.ball {
  animation: bounce 1s infinite alternate;
  -webkit-animation: bounce 1s infinite alternate;
}

@keyframes bounce {
  from {
    margin-top: 0;
  }
  to {
    margin-top: -15px;
  }
}

There is another simple way using HTML and CSS only!

Just wrap your <img> tag with div like so:

<div class="image-wrapper">
    <img src="http://dummyimage.com/100x100/000/fff">
</div>

Then, in your CSS file hide the img and set the background image for the wrapping div element:

.image-wrapper:hover {
    background-image: url(http://dummyimage.com/100x100/eb00eb/fff);
    background-size: contain;
    background-repeat: no-repeat;
}

.image-wrapper:hover img {
    display: none;
}

Et voilà!

You can use the centos-sclo-rh-testing repo to install GCC v7 without having to compile it forever, also enable V7 by default and let you switch between different versions if required.

sudo yum install -y yum-utils centos-release-scl;
sudo yum -y --enablerepo=centos-sclo-rh-testing install devtoolset-7-gcc;
echo "source /opt/rh/devtoolset-7/enable" | sudo tee -a /etc/profile;
source /opt/rh/devtoolset-7/enable;
gcc --version;

Code::Blocks is cross-platform, using the wxWidgets library. It's the one I use.

SQL Server allows the following (be careful to use single quotes instead of double)

UPDATE User
SET UserId = 12345
   , Name = 'J Doe'
   , Location = 'USA'
   , Bio='my bio
spans 
multiple
lines!'
WHERE UserId = 12345

ALTER TABLE test1 ADD COLUMN id SERIAL PRIMARY KEY;

This is all you need to:

1. Add the id column
2. Populate it with a sequence from 1 to count(*).
3. Set it as primary key / not null.

I wanted to match a particular if block in java

   ...
   ...
   if(isTrue){
       doAction();

   }
...
...
}

If I use the regExp

if \(isTrue(.|\n)*}

it included the closing brace for the method block so I used

if \(!isTrue([^}.]|\n)*}

to exclude the closing brace from the wildcard match.

I had the same error show up while creating the project but I wasn't behind a proxy and hence the above solutions did not work for me.

I found this forum. It suggested to:

1. Delete or Rename .m2 directory from your HOME directory

In Windows - C:\Users\<username>\Windows

OR

In Linux - /home/<username>

2. restart the Eclipse / STS spring tool suite (which am using)

It worked!

There are two BeanUtils.copyProperties(parameter1, parameter2) in Java.

One is

org.apache.commons.beanutils.BeanUtils.copyProperties(Object dest, Object orig)

Another is

org.springframework.beans.BeanUtils.copyProperties(Object source, Object target)

Pay attention to the opposite position of parameters.

Checking if "words" exists and then removing from the document

    db.users.update({"tags.words" :{$exists: true}},
                                           {$unset:{"tags.words":1}},false,true);

true indicates update multiple documents if matched.

http://www.mail-archive.com/[email protected]/msg03998.html says:

...and .removeClass() would remove all classes...

It works for me ;)

cheers

export is a Bash builtin, echo is an executable in your $PATH. So export is interpreted by Bash as is, without spawning a new process.

You need to get Bash to interpret your command, which you can pass as a string with the -c option:

bash -c "export foo=bar; echo \$foo"

ALSO:

Each invocation of bash -c starts with a fresh environment. So something like:

bash -c "export foo=bar"
bash -c "echo \$foo"

will not work. The second invocation does not remember foo.

Instead, you need to chain commands separated by ; in a single invocation of bash -c:

bash -c "export foo=bar; echo \$foo"

A simple (and maybe simplistic) answer to the question is the content of $x numeric is the following:

if ($x  eq  $x+0) { .... }

It does a textual comparison of the original $x with the $x converted to a numeric value.

VB6/VBA uses deterministic approach to destoying objects. Each object stores number of references to itself. When the number reaches zero, the object is destroyed.

Object variables are guaranteed to be cleaned (set to Nothing) when they go out of scope, this decrements the reference counters in their respective objects. No manual action required.

There are only two cases when you want an explicit cleanup:

1. When you want an object to be destroyed before its variable goes out of scope (e.g., your procedure is going to take long time to execute, and the object holds a resource, so you want to destroy the object as soon as possible to release the resource).

2. When you have a circular reference between two or more objects.

   If objectA stores a references to objectB, and objectB stores a reference to objectA, the two objects will never get destroyed unless you brake the chain by explicitly setting objectA.ReferenceToB = Nothing or objectB.ReferenceToA = Nothing.

The code snippet you show is wrong. No manual cleanup is required. It is even harmful to do a manual cleanup, as it gives you a false sense of more correct code.

If you have a variable at a class level, it will be cleaned/destroyed when the class instance is destructed. You can destroy it earlier if you want (see item 1.).

If you have a variable at a module level, it will be cleaned/destroyed when your program exits (or, in case of VBA, when the VBA project is reset). You can destroy it earlier if you want (see item 1.).

Access level of a variable (public vs. private) does not affect its life time.

If nothing mentioned in the above comments is working for you. It might mean the problem lies somewhere else.

One place I found the solution was in the way I was setting the list to the adapter. In my activity the list was a instance variable and I was changing it directly when any data changed. Due to it being a reference variable there was something weird going on. So I changed the reference variable to a local one and used another variable to update data and then pass to addAll() function mentioned in above answers.

He is using a outside div with a class for resolving this issue.

In this case, your test.js will not run, because you're loading it before jQuery. put it after jQuery:

<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.8.3/jquery.min.js"></script>
<script src="http://code.jquery.com/ui/1.9.2/jquery-ui.js"></script>
<script type="text/javascript" src="test.js"></script>

When I need full control over the callback, I create another attribute that is used as a switch. Simple and effective:

Model:

class MyModel < ActiveRecord::Base
  before_save :do_stuff, unless: :skip_do_stuff_callback
  attr_accessor :skip_do_stuff_callback

  def do_stuff
    puts 'do stuff callback'
  end
end

Test:

m = MyModel.new()

# Fire callbacks
m.save

# Without firing callbacks
m.skip_do_stuff_callback = true
m.save

# Fire callbacks again
m.skip_do_stuff_callback = false
m.save

Because the dataset property wasn't supported by Internet Explorer until version 11, you may want to use getAttribute() instead:

document.getElementById("the-span").addEventListener("click", function(){
  console.log(this.getAttribute('data-type'));
});

Minor update on top of Karthik Bose's answer - you can configure git globally, to affect all of your workspaces to behave that way:

git config --global push.default upstream

Just to add to the fix craze, putting {border:1px solid #???} around the badly looking object fixes the issue for me. In case you have a stable background colour, consider this too. This is so dumb noone thought about mentioning I guess, eh eh.

I want to add that when using Windows you can use require './1.rb' if the script is run local or from a mapped network drive but when run from an UNC \\servername\sharename\folder path you need to use require_relative './1.rb'.

I don't mingle in the discussion which to use for other reasons.

Just for the reference, if you work in scripts (batch processing), not in stored procedure, flushing output is triggered by the GO command, e.g.

print 'test'
print 'test'
go

In general, my conclusion is following: output of mssql script execution, executing in SMS GUI or with sqlcmd.exe, is flushed to file, stdoutput, gui window on first GO statement or until the end of the script.

Flushing inside of stored procedure functions differently, since you can not place GO inside.

Reference: tsql Go statement

If should be if. Your program should look like this:

answer = raw_input("Is the information correct? Enter Y for yes or N for no")
if answer.upper() == 'Y':
    print("this will do the calculation")
else:
    exit()

Note also that the indentation is important, because it marks a block in Python.

Microsoft lead for several way of hashing...

//for classes that contain a single int value
return this.value;

//for classes that contain multiple int value
return x ^ y;

//for classes that contain single number bigger than int    
return ((int)value ^ (int)(value >> 32)); 

//for classes that contain class instance fields which inherit from object
return obj1.GetHashCode();

//for classes that contain multiple class instance fields which inherit from object
return obj1.GetHashCode() ^ obj2.GetHashCode() ^ obj3.GetHashCode(); 

I can guess that for multiple big int you can use this:

int a=((int)value1 ^ (int)(value1 >> 32));
int b=((int)value2 ^ (int)(value2 >> 32));
int c=((int)value3 ^ (int)(value3 >> 32));
return a ^ b ^ c;

And same for multi-type: all converted first to int using GetHashCode() then the int values will be xor'ed and the result is your hash.

For those who use hash as ID (I mean an unique value), hash is naturally limited to a number of digits, I think it was 5 bytes for hashing algorithm, at least MD5.

You may turn multiple values to a hashed value and some of them be same, so don't use it as an identifier. (maybe some day I am going to use your component)

Following Adam's idea. Make your prepared statement sort of select my_column from my_table where search_column in (#) Create a String x and fill it with a number of "?,?,?" depending on your list of values Then just change the # in the query for your new String x an populate

You can't reference an alias except in ORDER BY because SELECT is the second last clause that's evaluated. Two workarounds:

SELECT BalanceDue FROM (
  SELECT (InvoiceTotal - PaymentTotal - CreditTotal) AS BalanceDue
  FROM Invoices
) AS x
WHERE BalanceDue > 0;

Or just repeat the expression:

SELECT (InvoiceTotal - PaymentTotal - CreditTotal) AS BalanceDue
FROM Invoices
WHERE  (InvoiceTotal - PaymentTotal - CreditTotal)  > 0;

I prefer the latter. If the expression is extremely complex (or costly to calculate) you should probably consider a computed column (and perhaps persisted) instead, especially if a lot of queries refer to this same expression.

PS your fears seem unfounded. In this simple example at least, SQL Server is smart enough to only perform the calculation once, even though you've referenced it twice. Go ahead and compare the plans; you'll see they're identical. If you have a more complex case where you see the expression evaluated multiple times, please post the more complex query and the plans.

Here are 5 example queries that all yield the exact same execution plan:

SELECT LEN(name) + column_id AS x
FROM sys.all_columns
WHERE LEN(name) + column_id > 30;

SELECT x FROM (
SELECT LEN(name) + column_id AS x
FROM sys.all_columns
) AS x
WHERE x > 30;

SELECT LEN(name) + column_id AS x
FROM sys.all_columns
WHERE column_id + LEN(name) > 30;

SELECT name, column_id, x FROM (
SELECT name, column_id, LEN(name) + column_id AS x
FROM sys.all_columns
) AS x
WHERE x > 30;

SELECT name, column_id, x FROM (
SELECT name, column_id, LEN(name) + column_id AS x
FROM sys.all_columns
) AS x
WHERE LEN(name) + column_id > 30;

Resulting plan for all five queries:

I propose two short solutions without recursion. They are not optimal from a computational complexity point of view, but work fine in average cases:

let a = [1, [2, 3], [[4], 5, 6], 7, 8, [9, [[10]]]];

// Solution #1
while (a.find(x => Array.isArray(x)))
    a = a.reduce((x, y) => x.concat(y), []);

// Solution #2
let i = a.findIndex(x => Array.isArray(x));
while (i > -1)
{
    a.splice(i, 1, ...a[i]);
    i = a.findIndex(x => Array.isArray(x));
}

The short answer is no. You can play a bit, if you want:

You can always do something like this:

private enum Base
{
    A,
    B,
    C
}

private enum Consume
{
    A = Base.A,
    B = Base.B,
    C = Base.C,
    D,
    E
}

But, it doesn't work all that great because Base.A != Consume.A

You can always do something like this, though:

public static class Extensions
{
    public static T As<T>(this Consume c) where T : struct
    {
        return (T)System.Enum.Parse(typeof(T), c.ToString(), false);
    }
}

In order to cross between Base and Consume...

You could also cast the values of the enums as ints, and compare them as ints instead of enum, but that kind of sucks too.

The extension method return should type cast it type T.

setInterval is the function you want. That repeats every x miliseconds.

window.setInterval(function() {
    alert('test');
}, 10000);

You should add client option to your mysql-connector allowPublicKeyRetrieval=true to allow the client to automatically request the public key from the server. Note that AllowPublicKeyRetrieval=True could allow a malicious proxy to perform a MITM attack to get the plaintext password, so it is False by default and must be explicitly enabled.

https://mysql-net.github.io/MySqlConnector/connection-options/

you could also try adding useSSL=false when you use it for testing/develop purposes

example:

jdbc:mysql://localhost:3306/db?allowPublicKeyRetrieval=true&useSSL=false

You can, use:

if (date >= startDate && date<= EndDate) { return true; }

You could do

[A1].Value = "'O1/01/13 00:00"

if you really mean to add it as text (note the apostrophe as the first character).

The [A1].Value is VBA shorthand for Range("A1").Value.

If you want to enter a date, you could instead do (edited order with thanks to @SiddharthRout):

[A1].NumberFormat = "mm/dd/yyyy hh:mm;@"
[A1].Value = DateValue("01/01/2013 00:00")

I just watched the 30 minute Unity Dependency Injection IoC Screencast by David Hayden and felt that was a good explaination with examples. Here is a snippet from the show notes:

The screencast shows several common usages of the Unity IoC, such as:

• Creating Types Not In Container
• Registering and Resolving TypeMappings
• Registering and Resolving Named TypeMappings
• Singletons, LifetimeManagers, and the ContainerControlledLifetimeManager
• Registering Existing Instances
• Injecting Dependencies into Existing Instances
• Populating the UnityContainer via App.config / Web.config
• Specifying Dependencies via Injection API as opposed to Dependency Attributes
• Using Nested ( Parent-Child ) Containers

I personally like to view the diff in GitHub prior to opening the PR. Additionally, I prefer writing the PR description on GitHub.

For those reasons, I made an alias (or technically a function without arguments), that opens the diff in GitHub between your current branch and master. If you add this to your .zshrc or .bashrc, you will be able to simply type open-pr and see your changes in GitHub. FYI, you will need to have your changes pushed.

function open-pr() {
  # Get the root of the github project, based on where you are configured to push to.  Ex: https://github.com/tensorflow/tensorflow
  base_uri=$(git remote -v | grep push | tr '\t' ' ' | cut -d ' ' -f 2 | rev | cut -d '.' -f 2- | rev)

  # Get your current branch name
  branch=$(git branch --show-current)

  # Create PR url and open in the default web browser
  url="${base_uri}/compare/${branch}/?expand=1"
  open $url
}

Just come across this, the answer is simple, use ISNULL. SQL won't return rows if the field you are testing has no value (in some of the records) when doing a text comparison search, eg:

WHERE wpp.comment NOT LIKE '%CORE%'

So, you have temporarily substitute a value in the null (empty) records by using the ISNULL command, eg

WHERE (ISNULL(wpp.comment,'')) NOT LIKE '%CORE%'

This will then show all your records that have nulls and omit any that have your matching criteria. If you wanted, you could put something in the commas to help you remember, eg

WHERE (ISNULL(wpp.comment,'some_records_have_no_value')) NOT LIKE '%CORE%'

You want something more like this:

SELECT TableA.*, TableB.*, TableC.*, TableD.*
FROM TableA
    JOIN TableB
        ON TableB.aID = TableA.aID
    JOIN TableC
        ON TableC.cID = TableB.cID
    JOIN TableD
        ON TableD.dID = TableA.dID
WHERE DATE(TableC.date)=date(now()) 

In your example, you are not actually including TableD. All you have to do is perform another join just like you have done before.

A note: you will notice that I removed many of your parentheses, as they really are not necessary in most of the cases you had them, and only add confusion when trying to read the code. Proper nesting is the best way to make your code readable and separated out.

The Replace/Len test is cute, but probably very inefficient (especially in terms of memory). A simple function with a loop will do the job.

CREATE FUNCTION [dbo].[fn_Occurences] 
(
    @pattern varchar(255),
    @expression varchar(max)
)
RETURNS int
AS
BEGIN

    DECLARE @Result int = 0;

    DECLARE @index BigInt = 0
    DECLARE @patLen int = len(@pattern)

    SET @index = CHARINDEX(@pattern, @expression, @index)
    While @index > 0
    BEGIN
        SET @Result = @Result + 1;
        SET @index = CHARINDEX(@pattern, @expression, @index + @patLen)
    END

    RETURN @Result

END

df.loc[:,df.columns.str.contains("spike")]

[0] or .First() will give you the same performance whatever happens.
But your Dictionary could contains IEnumerable<Component> instead of List<Component>, and then you cant use the [] operator. That is where the difference is huge.

So for your example, it doesn't really matters, but for this code, you have no choice to use First():

var dic = new Dictionary<String, IEnumerable<Component>>();
foreach (var components in dic.Values)
{
    // you can't use [0] because components is an IEnumerable<Component>
    var firstComponent = components.First(); // be aware that it will throw an exception if components is empty.
    var depCountry = firstComponent.ComponentValue("Dep");
}

I've used the below before, and it has worked. It isn't very pretty, but you can alter it to suit your needs.

The following JavaScript function grabs the location.href & document.title for the sharer, and you can ultimately change these.

function fbs_click() {
        u=location.href;
        t=document.title;
window.open('http://www.facebook.com/sharer.php?u='+encodeURIComponent(u)+'&t='+encodeURIComponent(t),
                'sharer',
                'toolbar=0,status=0,width=626,height=436');

            return false;
        }

Usage:

<a rel="nofollow" href="http://www.facebook.com/share.php?u=<;url>" onclick="return fbs_click()" target="_blank">
    Share on Facebook
</a>

It looks like this is what you could possibly be looking for: Facebook sharer title / desc....

this is the pattern I would use

$string = preg_replace('@[\s]{2,}@',' ',$string);

var arr = ["I", "am", "", "still", "here", "", "man"]
// arr = ["I", "am", "", "still", "here", "", "man"]
arr = arr.filter(Boolean)
// arr = ["I", "am", "still", "here", "man"]

filter documentation

// arr = ["I", "am", "", "still", "here", "", "man"]
arr = arr.filter(v=>v!='');
// arr = ["I", "am", "still", "here", "man"]

This is what I have so far:

UsernamePasswordAuthenticationFilter is only used for /login, and latter filters are not?

No, UsernamePasswordAuthenticationFilter extends AbstractAuthenticationProcessingFilter, and this contains a RequestMatcher, that means you can define your own processing url, this filter only handle the RequestMatcher matches the request url, the default processing url is /login.

Later filters can still handle the request, if the UsernamePasswordAuthenticationFilter executes chain.doFilter(request, response);.

More details about core fitlers

Does the form-login namespace element auto-configure these filters?

UsernamePasswordAuthenticationFilter is created by <form-login>, these are Standard Filter Aliases and Ordering

Does every request (authenticated or not) reach FilterSecurityInterceptor for non-login url?

It depends on whether the before fitlers are successful, but FilterSecurityInterceptor is the last fitler normally.

Does configuring two http elements create two springSecurityFitlerChains?

Yes, every fitlerChain has a RequestMatcher, if the RequestMatcher matches the request, the request will be handled by the fitlers in the fitler chain.

The default RequestMatcher matches all request if you don't config the pattern, or you can config the specific url (<http pattern="/rest/**").

If you want to konw more about the fitlers, I think you can check source code in spring security. doFilter(ServletRequest request, ServletResponse response, FilterChain filterChain)

I have an implementation which allows the activity to be destroyed on a screen orientation change, but still destroys the dialog in the recreated activity successfully. I use ...NonConfigurationInstance to attach the background task to the recreated activity. The normal Android framework handles recreating the dialog itself, nothing is changed there.

I subclassed AsyncTask adding a field for the 'owning' activity, and a method to update this owner.

class MyBackgroundTask extends AsyncTask<...> {
  MyBackgroundTask (Activity a, ...) {
    super();
    this.ownerActivity = a;
  }

  public void attach(Activity a) {
    ownerActivity = a;
  }

  protected void onPostExecute(Integer result) {
    super.onPostExecute(result);
    ownerActivity.dismissDialog(DIALOG_PROGRESS);
  }

  ...
}

In my activity class I added a field backgroundTask referring to the 'owned' backgroundtask, and I update this field using onRetainNonConfigurationInstance and getLastNonConfigurationInstance.

class MyActivity extends Activity {
  public void onCreate(Bundle savedInstanceState) {
    ...
    if (getLastNonConfigurationInstance() != null) {
      backgroundTask = (MyBackgroundTask) getLastNonConfigurationInstance();
      backgroundTask.attach(this);
    }
  }

  void startBackgroundTask() {
    backgroundTask = new MyBackgroundTask(this, ...);
    showDialog(DIALOG_PROGRESS);
    backgroundTask.execute(...);
  }

  public Object onRetainNonConfigurationInstance() {
    if (backgroundTask != null && backgroundTask.getStatus() != Status.FINISHED)
      return backgroundTask;
    return null;
  }
  ...
}

Suggestions for further improvement:

• Clear the backgroundTask reference in the activity after the task is finished to release any memory or other resources associated with it.
• Clear the ownerActivity reference in the backgroundtask before the activity is destroyed in case it will not be recreated immediately.
• Create a BackgroundTask interface and/or collection to allow different types of tasks to run from the same owning activity.

Unless you tell the development server that it's running in development mode, it will assume you're using it in production and warn you not to. The development server is not intended for use in production. It is not designed to be particularly efficient, stable, or secure.

Enable development mode by setting the FLASK_ENV environment variable to development.

$ export FLASK_APP=example
$ export FLASK_ENV=development
$ flask run

If you're running in PyCharm (or probably any other IDE) you can set environment variables in the run configuration.

Development mode enables the debugger and reloader by default. If you don't want these, pass --no-debugger or --no-reloader to the run command.

That warning is just a warning though, it's not an error preventing your app from running. If your app isn't working, there's something else wrong with your code.

downloaded Sql server management 2008 r2 and got it installed. Its getting installed but when I try to connect it via .\SQLEXPRESS it shows error. DO I need to install any SQL service on my system?

You installed management studio which is just a management interface to SQL Server. If you didn't (which is what it seems like) already have SQL Server installed, you'll need to install it in order to have it on your system and use it.

From the javadoc

@param  the sole object to be stored in the returned list.
@return an immutable list containing only the specified object.

example

import java.util.*;

public class HelloWorld {
    public static void main(String args[]) {
        // create an array of string objs
        String initList[] = { "One", "Two", "Four", "One",};

        // create one list
        List list = new ArrayList(Arrays.asList(initList));

        System.out.println("List value before: "+list);

        // create singleton list
        list = Collections.singletonList("OnlyOneElement");
        list.add("five"); //throws UnsupportedOperationException
        System.out.println("List value after: "+list);
    }
}

Use it when code expects a read-only list, but you only want to pass one element in it. singletonList is (thread-)safe and fast.

 CGRect buttonFrame = CGRectMake( x-pos, y-pos, width, height );   //
 CGRectMake(10,5,10,10) 

 UIButton *button = [[UIButton alloc] initWithFrame: buttonFrame];

 button setTitle: @"My Button" forState: UIControlStateNormal];

 [button addTarget:self action:@selector(btnClicked:) 
 forControlEvents:UIControlEventTouchUpInside];

 [button setTitleColor: [UIColor BlueVolor] forState:
 UIControlStateNormal];

 [view addSubview:button];




 -(void)btnClicked {
    // your code }

To get the all selected Items in a CheckedListBox try this:

In this case ths value is a String but it's run with other type of Object:

for (int i = 0; i < myCheckedListBox.Items.Count; i++)
{
    if (myCheckedListBox.GetItemChecked(i) == true)
    {

        MessageBox.Show("This is the value of ceckhed Item " + myCheckedListBox.Items[i].ToString());

    }

}

Inside your local project open the .bowerrc that contains:

{
   "directory": "bower_components"
 }

and add the following code-line:

{
   "directory": "bower_components",
  "proxy": "http://yourProxy:yourPort",
  "https-proxy":"http://yourProxy:yourPort"
}

bower version: 1.7.1

After reading all this and trying to fix it, I got a simple solution on ubuntu forum (https://help.ubuntu.com/community/ApacheMySQLPHP). The problem lies with libapache2-mod-php5 module. Thats why the browser downloads the index.php file rather than showing the web page. Do the following. If sudo a2enmod php5 returns module does not exist then the problem is with libapache2-mod-php5. Purge remove the module with command sudo apt-get --purge remove libapache2-mod-php5 Then install it again sudo apt-get install libapache2-mod-php5

The pack() method is defined in Window class in Java and it sizes the frame so that all its contents are at or above their preferred sizes.

This is because you have specified the form method as GET

Change code in the view to this:

using (@Html.BeginForm("myMethod", "Home", FormMethod.Post, new { id = @item.JobId })){
}

Are you using platform.system?

 system()
        Returns the system/OS name, e.g. 'Linux', 'Windows' or 'Java'.

        An empty string is returned if the value cannot be determined.

If that isn't working, maybe try platform.win32_ver and if it doesn't raise an exception, you're on Windows; but I don't know if that's forward compatible to 64-bit, since it has 32 in the name.

win32_ver(release='', version='', csd='', ptype='')
        Get additional version information from the Windows Registry
        and return a tuple (version,csd,ptype) referring to version
        number, CSD level and OS type (multi/single
        processor).

But os.name is probably the way to go, as others have mentioned.

if sys.platform == 'win32':
#---------
if os.environ.get('OS','') == 'Windows_NT':
#---------
try: import win32api
#---------
# Emulation using _winreg (added in Python 2.0) and
# sys.getwindowsversion() (added in Python 2.3)
import _winreg
GetVersionEx = sys.getwindowsversion
#----------
def system():

    """ Returns the system/OS name, e.g. 'Linux', 'Windows' or 'Java'.    
        An empty string is returned if the value cannot be determined.   
    """
    return uname()[0]

I've wrote a Java implementation based on the Sqlite's recommended way to do this:

private void dropColumn(SQLiteDatabase db,
        ConnectionSource connectionSource,
        String createTableCmd,
        String tableName,
        String[] colsToRemove) throws java.sql.SQLException {

    List<String> updatedTableColumns = getTableColumns(tableName);
    // Remove the columns we don't want anymore from the table's list of columns
    updatedTableColumns.removeAll(Arrays.asList(colsToRemove));

    String columnsSeperated = TextUtils.join(",", updatedTableColumns);

    db.execSQL("ALTER TABLE " + tableName + " RENAME TO " + tableName + "_old;");

    // Creating the table on its new format (no redundant columns)
    db.execSQL(createTableCmd);

    // Populating the table with the data
    db.execSQL("INSERT INTO " + tableName + "(" + columnsSeperated + ") SELECT "
            + columnsSeperated + " FROM " + tableName + "_old;");
    db.execSQL("DROP TABLE " + tableName + "_old;");
}

To get the table's column, I used the "PRAGMA table_info":

public List<String> getTableColumns(String tableName) {
    ArrayList<String> columns = new ArrayList<String>();
    String cmd = "pragma table_info(" + tableName + ");";
    Cursor cur = getDB().rawQuery(cmd, null);

    while (cur.moveToNext()) {
        columns.add(cur.getString(cur.getColumnIndex("name")));
    }
    cur.close();

    return columns;
}

I actually wrote about it on my blog, you can see more explanations there:

You need to include a body with the request. Angular removes the content-type header otherwise.

Add data: '' to the argument to $http.

I have used componentDidUpdate() in highchart.

Here is a simple example of this component.

import React, { PropTypes, Component } from 'react';
window.Highcharts = require('highcharts');

export default class Chartline extends React.Component {
  constructor(props) {
    super(props);
    this.state = {
      chart: ''
    };
  }

  public componentDidUpdate() {
    // console.log(this.props.candidate, 'this.props.candidate')
    if (this.props.category) {
      const category = this.props.category ? this.props.category : {};
      console.log('category', category);
      window.Highcharts.chart('jobcontainer_' + category._id, {
        title: {
          text: ''
        },
        plotOptions: {
          series: {
            cursor: 'pointer'
          }
        },
        chart: {
          defaultSeriesType: 'spline'
        },
        xAxis: {
          // categories: candidate.dateArr,
          categories: ['Day1', 'Day2', 'Day3', 'Day4', 'Day5', 'Day6', 'Day7'],
          showEmpty: true
        },
        labels: {
          style: {
            color: 'white',
            fontSize: '25px',
            fontFamily: 'SF UI Text'
          }
        },
        series: [
          {
            name: 'Low',
            color: '#9B260A',
            data: category.lowcount
          },
          {
            name: 'High',
            color: '#0E5AAB',
            data: category.highcount
          },
          {
            name: 'Average',
            color: '#12B499',
            data: category.averagecount
          }
        ]
      });
    }
  }
  public render() {
    const category = this.props.category ? this.props.category : {};
    console.log('render category', category);
    return <div id={'jobcontainer_' + category._id} style={{ maxWidth: '400px', height: '180px' }} />;
  }
}

Use below code to print the error code :

echo mysqli_errno($this->db_link);

Error code will give you better idea about the error.

rapidjson is a C++ JSON parser/generator designed to be fast and small memory footprint.

There is a performance comparison with YAJL and JsonCPP.

Update:

I created an open source project Native JSON benchmark, which evaluates 29 (and increasing) C/C++ JSON libraries, in terms of conformance and performance. This should be an useful reference.

I created an online tool to do this. Simply paste any dependency in pom file format, and the dependency tree for that artifact is generated, based on the central maven repository.
