I tried the binding according to the answer by @Szymon but It did not work for me. I tried basicHttpsBinding which is new in .net 4.5 and It solved the issue. Here is the complete configuration that works for me.

<system.serviceModel>
    <serviceHostingEnvironment aspNetCompatibilityEnabled="true" multipleSiteBindingsEnabled="false" />
    <behaviors>
      <serviceBehaviors>
        <behavior>
          <serviceMetadata httpGetEnabled="false" httpsGetEnabled="true"/>
          <serviceDebug includeExceptionDetailInFaults="true"/>
        </behavior>
      </serviceBehaviors>
    </behaviors>
    <bindings>
      <basicHttpsBinding>
        <binding name="basicHttpsBindingForYourService">
          <security mode="Transport">
            <transport clientCredentialType="None" proxyCredentialType="None"/>
          </security>
        </binding>
      </basicHttpsBinding>
    </bindings>
    <services>
      <service name="YourServiceName">
        <endpoint address="" binding="basicHttpsBinding" bindingName="basicHttpsBindingForYourService" contract="YourContract" />
      </service>
    </services>   
</system.serviceModel>

FYI: My application's target framework is 4.5.1. IIS web site that I created to deploy this wcf service only has https binding enabled.

Ensure that binary files are under "bin" subdirectory of your ".svc" file

I had the same issue. For me I noticed that the https is using another Certificate which was invalid in terms of expiration date. Not sure why it happened. I changed the Https port number and a new self signed cert. WCFtestClinet could connect to the server via HTTPS!

I had the same problem, got it working by "binding" de service with the service behaviour by doing this :

Gave a name to the behaviour

<serviceBehaviors>
        <behavior name="YourBehaviourNameHere">

And making a reference to your behaviour in your service

<services>
  <service name="WCFTradeLibrary.TradeService" behaviorConfiguration="YourBehaviourNameHere">

The whole thing would be :

<configuration>

    <compilation debug="true" />
  </system.web>
  <!-- When deploying the service library project, the content of the config file must be added to the host's

Change the customBinding in the web.config to use larger defaults. I picked 2MB as it is a reasonable size. Of course setting it to 2GB (as your code suggests) will work but it does leave you more vulnerable to attacks. Pick a size that is larger than your largest request but isn't overly large.

Check this : Using Large Message Requests in Silverlight with WCF

<system.serviceModel>
   <behaviors>
     <serviceBehaviors>

                contract="TestLargeWCF.Web.MyService"/>
       <endpoint address="mex"
                binding="mexHttpBinding"
                contract="IMetadataExchange"/>
     </service>
   </services>
 </system.serviceModel> 

Removing the name from your binding will make it apply to all endpoints, and should produce the desired results. As so:

<services>
  <service name="Service.IService">
    <clear />
    <endpoint binding="basicHttpBinding" contract="Service.IService" />
  </service>
</services>
<bindings>
  <basicHttpBinding>
    <binding maxBufferSize="2147483647" maxReceivedMessageSize="2147483647">
      <readerQuotas maxDepth="32" maxStringContentLength="2147483647"
        maxArrayLength="16348" maxBytesPerRead="4096" maxNameTableCharCount="16384" />
    </binding>
  </basicHttpBinding>
  <webHttpBinding>
    <binding maxBufferSize="2147483647" maxReceivedMessageSize="2147483647" />
  </webHttpBinding>
</bindings>

Also note that I removed the bindingConfiguration attribute from the endpoint node. Otherwise you would get an exception.

This same solution was found here : Problem with large requests in WCF

Change

<serviceMetadata httpsGetEnabled="true"/>

to

<serviceMetadata httpsGetEnabled="false"/>

You're telling WCF to use https for the metadata endpoint and I see that your'e exposing your service on http, and then you get the error in the title.

You also have to set <security mode="None" /> if you want to use HTTP as your URL suggests.

I was also getting the same error, the WCF was working properly for me when i was using it in the Dev Environment with my credentials, but when someone else was using it in TEST, it was throwing the same error. I did a lot of research, and then instead of doing config updates, handled an exception in the WCF method with the help of fault exception. Also the identity for the WCF needs to be set with the same credentials which are having access in the database, someone might have changed your authority. Please find below the code for the same:

 [ServiceContract]
public interface IService1
{
    [OperationContract]
    [FaultContract(typeof(ServiceData))]
    ForDataset GetCCDBdata();

    [OperationContract]
    [FaultContract(typeof(ServiceData))]
    string GetCCDBdataasXMLstring();


    //[OperationContract]
    //string GetData(int value);

    //[OperationContract]
    //CompositeType GetDataUsingDataContract(CompositeType composite);

    // TODO: Add your service operations here
}

  [DataContract]
public class ServiceData
{
    [DataMember]
    public bool Result { get; set; }
    [DataMember]
    public string ErrorMessage { get; set; }
    [DataMember]
    public string ErrorDetails { get; set; }
}

in your service1.svc.cs you can use this in the catch block:

 catch (Exception ex)
        {
            myServiceData.Result = false;
            myServiceData.ErrorMessage = "unforeseen error occured. Please try later.";
            myServiceData.ErrorDetails = ex.ToString();
            throw new FaultException<ServiceData>(myServiceData, ex.ToString());
        }

And use this in the Client application like below code:

  ConsoleApplicationWCFClient.CCDB_HIG_service.ForDataset ds = obj.GetCCDBdata();

            string str = obj.GetCCDBdataasXMLstring();

        }

        catch (FaultException<ConsoleApplicationWCFClient.CCDB_HIG_service.ServiceData> Fex)
      {
          Console.WriteLine("ErrorMessage::" + Fex.Detail.ErrorMessage + Environment.NewLine);
          Console.WriteLine("ErrorDetails::" + Environment.NewLine + Fex.Detail.ErrorDetails);
          Console.ReadLine();
      }

Just try this, it will help for sure to get the exact issue.

I had a similar issue. I resolved it by changing

<basicHttpBinding>

to

<basicHttpsBinding>

and also changed my URL to use https:// instead of http://.

Also in <endpoint> node, change

binding="basicHttpBinding" 

to

binding="basicHttpsBinding"

This worked.

In my case, the Webservice was generating the assembly with a different name than the project/service name. It was set like that by my predecessor developer working on the solution and I didn't know.

It was set to -

  <serviceBehaviors>
    <behavior name="CustomServiceBehavior">
      <serviceAuthorization serviceAuthorizationManagerType="BookingService.KeyAuthorizationManager, BookingService" />
     </behavior>
 </serviceBehaviors>

So, the fix was the put the right assembly name in serviceAuthorizationManagerType. The assembly name can be obtained from following path of the service project: Right click on the WCF svc project--> Select "Properties" --> From the list of tabs select "Application". Check the value against "Assembly name:" field in the list. This is the assemblyName to use for serviceAuthorizationManagerType which may not be the servicename necessarily.

  <serviceBehaviors>
    <behavior name="MyCustomServiceBehavior">
      <serviceAuthorization serviceAuthorizationManagerType="BookingService.KeyAuthorizationManager, AssemblyNameFromSvcProperties" />
     </behavior>
 </serviceBehaviors>

remember to follow the instruction for serviceAuthorizationManagerType as mentioned on https://docs.microsoft.com/en-us/dotnet/framework/wcf/extending/how-to-create-a-custom-authorization-manager-for-a-service

It says -

Warning

Note that when you specify the serviceAuthorizationManagerType, the string must contain the fully qualified type name. a comma, and the name of the assembly in which the type is defined. If you leave out the assembly name, WCF will attempt to load the type from System.ServiceModel.dll.

My solution, having encountered the same error message, was even simpler than the ones above, I just updated the to basicHttpsBinding>

  <bindings>
    <basicHttpsBinding>
    <binding name="ShipServiceSoap" maxBufferPoolSize="512000" maxReceivedMessageSize="512000" />
    </basicHttpsBinding>
    </bindings>

And the same in the section below:

  <client>
    <endpoint address="https://s.asmx" binding="basicHttpsBinding" bindingConfiguration="ShipServiceSoap" contract="..ServiceSoap" name="ShipServiceSoap" />
    </client>

I'm not a WCF expert but I'm wondering if you aren't running into a DDOS protection on IIS. I know from experience that if you run a bunch of simultaneous connections from a single client to a server at some point the server stops responding to the calls as it suspects a DDOS attack. It will also hold the connections open until they time-out in order to slow the client down in his attacks.

Multiple connection coming from different machines/IP's should not be a problem however.

There's more info in this MSDN post:

http://msdn.microsoft.com/en-us/library/bb463275.aspx

Check out the MaxConcurrentSession sproperty.

Only the first base address in the list will be taken over (coming from IIS). You can't have multiple base addresses per scheme prior to .NET4.

It might be useful to debug the client, turn off Tools\Options\Debugging\General\'Enable Just My Code', click Debug\Exceptions\'catch all first-chance exceptions' for managed CLR exceptions, and see if there is an exception under-the-hood on the client before the protocol exception and before the message hits the wire. (My guess would be some kind of serialization failure.)

This problem occures when you use your service via other application.If application has config file just add your service config information to this file. In my situation there wasn't any config file so I use this technique and it worked fine.Just store url address in application,read it and using BasicHttpBinding() method send it to service application as parameter.This is simple demonstration how I did it:

Configuration config = new Configuration(dataRowSet[0]["ServiceUrl"].ToString());

var remoteAddress = new System.ServiceModel.EndpointAddress(config.Url);


SimpleService.PayPointSoapClient client = 
    new SimpleService.PayPointSoapClient(new System.ServiceModel.BasicHttpBinding(), 
    remoteAddress);
SimpleService.AccountcredResponse response = client.AccountCred(request);

A more efficient way, in my opinion, is to have another list that you declare that you put anything that is "to be removed" into. Then after you finish your main loop (without the .ToList()), you do another loop over the "to be removed" list, removing each entry as it happens. So in your class you add:

private List<Guid> toBeRemoved = new List<Guid>();

Then you change it to:

public void NotifySubscribers(DataRecord sr)
{
    toBeRemoved.Clear();

    ...your unchanged code skipped...

   foreach ( Guid clientId in toBeRemoved )
   {
        try
        {
            subscribers.Remove(clientId);
        }
        catch(Exception e)
        {
            System.Diagnostics.Debug.WriteLine("Unsubscribe Error " + 
                e.Message);
        }
   }
}

...your unchanged code skipped...

public void UnsubscribeEvent(Guid clientId)
{
    toBeRemoved.Add( clientId );
}

This will not only solve your problem, it will prevent you from having to keep creating a list from your dictionary, which is expensive if there are a lot of subscribers in there. Assuming the list of subscribers to be removed on any given iteration is lower than the total number in the list, this should be faster. But of course feel free to profile it to be sure that's the case if there's any doubt in your specific usage situation.

if needed to specify domain(which authecticates username and password that client uses) in webconfig you can put this in system.serviceModel services service section:

<identity>          
<servicePrincipalName value="example.com" />
</identity>

and in client specify domain and username and password:

 client.ClientCredentials.Windows.ClientCredential.Domain = "example.com";
 client.ClientCredentials.Windows.ClientCredential.UserName = "UserName ";
 client.ClientCredentials.Windows.ClientCredential.Password = "Password";

It's crude, but:

set pagesize 0 linesize 500 trimspool on feedback off echo off

select '"' || empno || '","' || ename || '","' || deptno || '"' as text
from emp

spool emp.csv
/
spool off

In html use

<input :required="condition" />

And define in data property like

data () {
   return {
      condition: false
   }
}

JavaScript code runs on a single thread, so you cannot principally block to wait for the first loop iteration to complete before beginning the next without seriously impacting page usability.

The solution depends on what you really need. If the example is close to exactly what you need, @Simon's suggestion to pass i to your async process is a good one.

Make sure the files are writeable (not read-only), and that your user has write permissions on them.

Also, on most recent systems, the Program Files directory is read-only. Try to place the files in another directory.

self (not $self) refers to the type of class, where as $this refers to the current instance of the class. self is for use in static member functions to allow you to access static member variables. $this is used in non-static member functions, and is a reference to the instance of the class on which the member function was called.

Because this is an object, you use it like: $this->member

Because self is not an object, it's basically a type that automatically refers to the current class, you use it like: self::member

It depends on what database you are using. In MySQL, you would use the "ALTER TABLE" syntax. I don't remember exactly how, but it would go something like this if you wanted to add a column called 'newcol' that was a 200 character varchar:

ALTER TABLE example ADD newCol VARCHAR(200) AFTER otherCol;

If you simply need to view the table and run queries on it you can use this third party sdf viewer. It is a lightweight viewer that has all the basic functionalities and is ready to use after install.

and ofcourse, its Free.

As @cs95 mentioned in a comment, to drop only one level, use:

df.reset_index(level=[...])

This avoids having to redefine your desired index after reset.

While the example works, its not the correct way to handle the streams...

You need to ensure the closing of the files/streams with the using clause.. Also, add try/catch to handle IO errors...

       public void DownloadAll()
    {
        string host = @"sftp.domain.com";
        string username = "myusername";
        string password = "mypassword";

        string remoteDirectory = "/RemotePath/";
        string localDirectory = @"C:\LocalDriveFolder\Downloaded\";

        using (var sftp = new SftpClient(host, username, password))
        {
            sftp.Connect();
            var files = sftp.ListDirectory(remoteDirectory);

            foreach (var file in files)
            {
                string remoteFileName = file.Name;
                if ((!file.Name.StartsWith(".")) && ((file.LastWriteTime.Date == DateTime.Today))

                    using (Stream file1 = File.OpenWrite(localDirectory + remoteFileName))
                    { 
                        sftp.DownloadFile(remoteDirectory + remoteFileName, file1);
                    }
            }

        }
    }

Sure, Xcode->Preferences and turn on Show line numbers.

Try this:

var frm = document.getElementById('search-theme-form') || null;
if(frm) {
   frm.action = 'whatever_you_need.ext' 
}

Unfortunately there is no SELECT statement that will always work regardless of database.

Most databases support:

SELECT 1

Some databases don't support this but have a table called DUAL that you can use when you don't need a table:

SELECT 1 FROM DUAL

MySQL also supports this for compatibility reasons, but not all databases do. A workaround for databases that don't support either of the above is to create a table called DUAL that contains a single row, then the above will work.

HSQLDB supports neither of the above, so you can either create the DUAL table or else use:

SELECT 1 FROM any_table_that_you_know_exists_in_your_database

You can't databind to a property and then explictly assign a value to the databound property.

Below is the ouput of above code-snippet:

You get this error because one of your variables is actually a factor variable . Execute

str(df) 

to check this. Then do this double variable change to keep the year numbers instead of transforming into "1,2,3,4" level numbers:

df$year <- as.numeric(as.character(df$year))

EDIT: it appears that your data.frame has a variable of class "array" which might cause the pb. Try then:

df <- data.frame(apply(df, 2, unclass))

and plot again?

Here is your string XOR'er, presumably for some mild form of encryption:

>>> src = "Hello, World!"
>>> code = "secret"
>>> xorWord = lambda ss,cc: ''.join(chr(ord(s)^ord(c)) for s,c in zip(ss,cc*100))
>>> encrypt = xorWord(src, code)
>>> encrypt
';\x00\x0f\x1e\nXS2\x0c\x00\t\x10R'
>>> decrypt = xorWord(encrypt,code)
>>> print decrypt
Hello, World!

Note that this is an extremely weak form of encryption. Watch what happens when given a blank string to encode:

>>> codebreak = xorWord("      ", code)
>>> print codebreak
SECRET

You could also repeat "0", prepend it to str(n) and get the rightmost width slice. Quick and dirty little expression.

def pad_left(n, width, pad="0"):
    return ((pad * width) + str(n))[-width:]

Other answers are correct, basically you had the wrong number of "y" characters in your pattern.

Time Zone

One more problem though… You did not address time zones. If you intended UTC, then you should have said so. If not, the answers are not complete. If all you want is the date portion without the time, then no issue. But if you do further work that may involve time, then you should be specifying a time zone.

Joda-Time

Here is the same kind of code but using the third-party open-source Joda-Time 2.3 library

// © 2013 Basil Bourque. This source code may be used freely forever by anyone taking full responsibility for doing so.

String date_s = "2011-01-18 00:00:00.0";

org.joda.time.format.DateTimeFormatter formatter = org.joda.time.format.DateTimeFormat.forPattern( "yyyy-MM-dd' 'HH:mm:ss.SSS" );
// By the way, if your date-time string conformed strictly to ISO 8601 including a 'T' rather than a SPACE ' ', you could
// use a formatter built into Joda-Time rather than specify your own: ISODateTimeFormat.dateHourMinuteSecondFraction().
// Like this:
//org.joda.time.DateTime dateTimeInUTC = org.joda.time.format.ISODateTimeFormat.dateHourMinuteSecondFraction().withZoneUTC().parseDateTime( date_s );

// Assuming the date-time string was meant to be in UTC (no time zone offset).
org.joda.time.DateTime dateTimeInUTC = formatter.withZoneUTC().parseDateTime( date_s );
System.out.println( "dateTimeInUTC: " + dateTimeInUTC );
System.out.println( "dateTimeInUTC (date only): " + org.joda.time.format.ISODateTimeFormat.date().print( dateTimeInUTC ) );
System.out.println( "" ); // blank line.

// Assuming the date-time string was meant to be in Kolkata time zone (formerly known as Calcutta). Offset is +5:30 from UTC (note the half-hour).
org.joda.time.DateTimeZone kolkataTimeZone = org.joda.time.DateTimeZone.forID( "Asia/Kolkata" );
org.joda.time.DateTime dateTimeInKolkata = formatter.withZone( kolkataTimeZone ).parseDateTime( date_s );
System.out.println( "dateTimeInKolkata: " + dateTimeInKolkata );
System.out.println( "dateTimeInKolkata (date only): " + org.joda.time.format.ISODateTimeFormat.date().print( dateTimeInKolkata ) );
// This date-time in Kolkata is a different point in the time line of the Universe than the dateTimeInUTC instance created above. The date is even different.
System.out.println( "dateTimeInKolkata adjusted to UTC: " + dateTimeInKolkata.toDateTime( org.joda.time.DateTimeZone.UTC ) );

When run…

dateTimeInUTC: 2011-01-18T00:00:00.000Z
dateTimeInUTC (date only): 2011-01-18

dateTimeInKolkata: 2011-01-18T00:00:00.000+05:30
dateTimeInKolkata (date only): 2011-01-18
dateTimeInKolkata adjusted to UTC: 2011-01-17T18:30:00.000Z

A slightly different approach - the payload is too BIG

All the helpful answers so far deal with increasing the payload limit. But it might also be the case that the payload is indeed too big but for no good reason. If there's no valid reason for it to be, consider looking into why it's so bloated in the first place.

Our own experience

For example, in our case, an Angular app was greedily sending an entire object in the payload. When one bloated and redundant property was removed, the payload size was reduced by a factor of a 100. This significantly improved performance and resolved the 413 error.

To expand on what Peter said: Since you are looking to go from interface{} to string, type assertion will lead to headaches since you need to account for multiple incoming types. You'll have to assert each type possible and verify it is that type before using it.

Using fmt.Sprintf (https://golang.org/pkg/fmt/#Sprintf) automatically handles the interface conversion. Since you know your desired output type is always a string, Sprintf will handle whatever type is behind the interface without a bunch of extra code on your behalf.

Yes, the garbage collector will remove them as well. Might not always be the case with legacy browsers though.

No answer so far mentions eu-strip --strip-debug -f <out.debug> <input>.

• This is provided by elfutils package.
• The result will be that <input> file has been stripped of debug symbols which are now all in <out.debug>.

To everyone who said that this is a bad idea I want to say it is not always a bad one. Sometimes it is very boring to have to zoom out to see all the content. For example when you type on an input on iOS it zooms to get it in the center of the screen. You have to zoom out after that cause closing the keyboard does not do the work. Also I agree that when you put many I hours in making a great layout and user experience you don't want it to be messed up by a zoom.

But the other argument is valuable as well for people with vision issues. However In my opinion if you have issues with your eyes you are already using the zooming features of the system so there is no need to disturb the content.

If you want the logo to take space, you are probably better of floating it left and then moving down the content using margin, sort of like this:

#logo {
    float: left;
    margin: 0 10px 10px 20px;
}

#content {
    margin: 10px 0 0 10px;
}

or whatever margin you want.

I think its simpler:

$('submit').click(function(e){
if (e.isValid())
   e.preventDefault();
//your code.
}

this will stop the submit until form is valid.

I would suggest instead of trying to extract the HTML from the WebView, you extract the HTML from the URL. By this, I mean using a third party library such as JSoup to traverse the HTML for you. The following code will get the HTML from a specific URL for you

public static String getHtml(String url) throws ClientProtocolException, IOException {
        HttpClient httpClient = new DefaultHttpClient();
        HttpContext localContext = new BasicHttpContext();
        HttpGet httpGet = new HttpGet(url);
        HttpResponse response = httpClient.execute(httpGet, localContext);
        String result = "";

        BufferedReader reader = new BufferedReader(
            new InputStreamReader(
                response.getEntity().getContent()
            )
        );

        String line = null;
        while ((line = reader.readLine()) != null){
            result += line + "\n";
        }
        return result;
    }

You can try proceeding this way:

Pass ms value from

Long ms = watch.getTime();

to

getDisplayValue(ms)

Kotlin implementation:

fun getDisplayValue(ms: Long): String {
        val duration = Duration.ofMillis(ms)
        val minutes = duration.toMinutes()
        val seconds = duration.minusMinutes(minutes).seconds

        return "${minutes}min ${seconds}sec"
}

Java implementation:

public String getDisplayValue(Long ms) {
        Duration duration = Duration.ofMillis(ms);
        Long minutes = duration.toMinutes();
        Long seconds = duration.minusMinutes(minutes).getSeconds();

        return minutes + "min " + seconds "sec"
}

For leaving the console window open you only have to add to the last command line in the batch file:

' & pause'

parentNode.insertBefore(newChild, refChild)

Inserts the node newChild as a child of parentNode before the existing child node refChild. (Returns newChild.)

If refChild is null, newChild is added at the end of the list of children. Equivalently, and more readably, use parentNode.appendChild(newChild).

They JKS file is just a container for certificates and key pairs. In a client-side authentication scenario, the various parts of the keys will be located here:

• The client's store will contain the client's private and public key pair. It is called a keystore.
• The server's store will contain the client's public key. It is called a truststore.

The separation of truststore and keystore is not mandatory but recommended. They can be the same physical file.

To set the filesystem locations of the two stores, use the following system properties:

-Djavax.net.ssl.keyStore=clientsidestore.jks

and on the server:

-Djavax.net.ssl.trustStore=serversidestore.jks

To export the client's certificate (public key) to a file, so you can copy it to the server, use

keytool -export -alias MYKEY -file publicclientkey.cer -store clientsidestore.jks

To import the client's public key into the server's keystore, use (as the the poster mentioned, this has already been done by the server admins)

keytool -import -file publicclientkey.cer -store serversidestore.jks

For iOS 8

  static NSString *_myCustomFontName;

 + (NSString *)myCustomFontName:(NSString*)fontName
  {
 if ( !_myCustomFontName )
  {
   NSArray *arr = [UIFont fontNamesForFamilyName:fontName];
    // I know I only have one font in this family
    if ( [arr count] > 0 )
       _myCustomFontName = arr[0];
  }

 return _myCustomFontName;

 }

We're using Kafka 2.11 and make use of this tool - kafka-consumer-groups.

$ rpm -qf /bin/kafka-consumer-groups
confluent-kafka-2.11-1.1.1-1.noarch

For example:

$ kafka-consumer-groups --describe --group logstash | grep -E "TOPIC|filebeat"

Random Tip

NOTE: We use an alias that overloads kafka-consumer-groups like so in our /etc/profile.d/kafka.sh:

alias kafka-consumer-groups="KAFKA_JVM_PERFORMANCE_OPTS=\"-Djava.security.auth.login.config=$HOME/.kafka_client_jaas.conf\"  kafka-consumer-groups --bootstrap-server ${KAFKA_HOSTS} --command-config /etc/kafka/security-enabler.properties"

Here is a useful article by Michael J. Swart on the matter, which covers different patterns and antipatterns for implementing UPSERT in SQL Server:
https://michaeljswart.com/2017/07/sql-server-upsert-patterns-and-antipatterns/

It addresses associated concurrency issues (primary key violations, deadlocks) - all of the answers provided here yet are considered antipatterns in the article (except for the @Bridge solution using triggers, which is not covered there).

Here is an extract from the article with the solution preferred by the author:

Inside a serializable transaction with lock hints:

CREATE PROCEDURE s_AccountDetails_Upsert ( @Email nvarchar(4000), @Etc nvarchar(max) )
AS 
  SET TRANSACTION ISOLATION LEVEL SERIALIZABLE;
  BEGIN TRAN

    IF EXISTS ( SELECT * FROM dbo.AccountDetails WITH (UPDLOCK) WHERE Email = @Email )

      UPDATE dbo.AccountDetails
         SET Etc = @Etc
       WHERE Email = @Email;

    ELSE 

      INSERT dbo.AccountDetails ( Email, Etc )
      VALUES ( @Email, @Etc );

  COMMIT

USe s3a instead of s3n. I had similar issue on a Hadoop job. After switching from s3n to s3a it worked.

e.g.

s3a://myBucket/myFile1.log

Raw CGI is kind of a pain, Django is kind of heavyweight. There are a number of simpler, lighter frameworks about, e.g. CherryPy. It's worth looking around a bit.

If you want more datesource configs e.g.

spring.datasource.test-while-idle=true 
spring.datasource.time-between-eviction-runs-millis=30000
spring.datasource.validation-query=select 1

you could use below code

@Bean
public DataSource dataSource() {
    DataSource dataSource = new DataSource(); // org.apache.tomcat.jdbc.pool.DataSource;
    dataSource.setDriverClassName(driverClassName);
    dataSource.setUrl(url);
    dataSource.setUsername(username);
    dataSource.setPassword(password);
    dataSource.setTestWhileIdle(testWhileIdle);     
    dataSource.setTimeBetweenEvictionRunsMillis(timeBetweenEvictionRunsMills);
    dataSource.setValidationQuery(validationQuery);
    return dataSource;
}

You can HashMap<MyHashObject,MyHashObject> instead of HashSet<MyHashObject>.

Calling ContainsKey() on your "reconstructed" MyHashObject will first hashCode()-check the collection, and if a duplicate hashcode is hit, finally equals()-check your "reconstructed" against the original, at which you can retrieve the original using get()

This is O(1) but the downside is you will likely have to override both equals() and hashCode() methods.

For those who are getting Error Unknown URI: content://downloads/public_downloads. I managed to solve this by getting a hint given by @Commonsware in this answer. I found out the class FileUtils on GitHub. Here InputStream methods are used to fetch file from Download directory.

 // DownloadsProvider
            else if (isDownloadsDocument(uri)) {

                final String id = DocumentsContract.getDocumentId(uri);

                if (id != null && id.startsWith("raw:")) {
                    return id.substring(4);
                }

                String[] contentUriPrefixesToTry = new String[]{
                        "content://downloads/public_downloads",
                        "content://downloads/my_downloads",
                        "content://downloads/all_downloads"
                };

                for (String contentUriPrefix : contentUriPrefixesToTry) {
                    Uri contentUri = ContentUris.withAppendedId(Uri.parse(contentUriPrefix), Long.valueOf(id));
                    try {
                        String path = getDataColumn(context, contentUri, null, null);
                        if (path != null) {
                            return path;
                        }
                    } catch (Exception e) {}
                }

                // path could not be retrieved using ContentResolver, therefore copy file to accessible cache using streams
                String fileName = getFileName(context, uri);
                File cacheDir = getDocumentCacheDir(context);
                File file = generateFileName(fileName, cacheDir);
                String destinationPath = null;
                if (file != null) {
                    destinationPath = file.getAbsolutePath();
                    saveFileFromUri(context, uri, destinationPath);
                }

                return destinationPath;
            }

I'd suggest perl. (\d+.\d+.\d+.\d+) should probably do the trick.

EDIT: Just to make it more like a complete program, you could do something like the following (not tested):

#!/usr/bin/perl -w
use strict;

while (<>) {
    if (/(\d+\.\d+\.\d+\.\d+)/) {
        print "$1\n";
    }
}

This handles one IP per line. If you have more than one IPs per line, you need to use the /g option. man perlretut gives you a more detailed tutorial on regular expressions.

Well, I have tried something I hope it helps ..

They changed the schema a little bit ..

Use the following :

1- Change the AccessDataSource to SQLDataSource in the toolbox.

2- In the drop down menu choose your access database (xxxx.accdb or xxxx.mdb)

3- Next -> Next -> Test Query -> Finish.

Worked for me.

I came across this question and inspired by other contributors. I need to append some content to a file once per line. Here is what I did.

class Doh {
   def ln = System.getProperty('line.separator')
   File file //assume it's initialized 

   void append(String content) {
       file << "$content$ln"
   }
}

Pretty neat I think :)

D or dd deletes and copies the line to the register. You can use Vx which only deletes the line and stays in the normal mode.

I recently had this problem and it ended up being a port issue. My production SQL Server was set up at to be port 1427 instead 1433.

Just change the connection string to be

...data source=MySQLServerName,1427;initial catalog=MyDBName...

Hope this helps anyone who might be seeing this same issue.

If anyone is using a Navigation Controller and wants all of their navigation controllers to have the black style, you can write an extension to UINavigationController like this in Swift 3 and it will apply to all navigation controllers (instead of assigning it to one controller at a time).

extension UINavigationController {

    override open func viewDidLoad() {
        super.viewDidLoad()

        self.navigationBar.barStyle = UIBarStyle.black
    }

}

I don't think this is possible. As far as I know, the only time a browser doesn't scroll to a changed document.location.hash is if the hash doesn't exist within the page.

This article isn't directly related to your question, but it discusses typical browser behavior of changing document.location.hash

Solution that worked for me for Excel Interop:

myWorksheet.Columns[j].NumberFormat = "@";      // column as a text
myWorksheet.Cells[i + 2, j].NumberFormat = "@"; // cell as a text

This code should run before putting data to Excel. Column and row numbers are 1-based.

A bit more details. Whereas accepted response with reference for SpreadsheetGear looks almost correct, I had two concerns about it:

1. I am not using SpreadsheetGear. I was interested in regular Excel communication thru Excel interop without any 3rdparty libraries,
2. I was searching for the way to format column by number, not using ranges like "A:A".

Save yourself a schizophrenic episode and use the Advanced Python scheduler: http://pythonhosted.org/APScheduler

The code is so simple:

from apscheduler.scheduler import Scheduler

sched = Scheduler()
sched.start()

def some_job():
    print "Every 10 seconds"

sched.add_interval_job(some_job, seconds = 10)

....
sched.shutdown()

ProcessStartInfo startInfo = new ProcessStartInfo(string.Concat(cPath, "\\", "HHTCtrlp.exe"));
startInfo.Arguments =cParams;
startInfo.UseShellExecute = false; 
System.Diagnostics.Process.Start(startInfo);

Maybe not very elegant, but it does the job:

exec(open("script.py").read())

If you want to add a bounding box, use a rectangle:

ax = plt.gca()
r = matplotlib.patches.Rectangle((.5, .5), .25, .1, fill=False)
ax.add_artist(r)

Since the question asked for either jQuery or vanilla JS, here's an answer with vanilla JS.

I've added some CSS to the demo below to change the button's font color to red when its aria-expanded is set to true

const button = document.querySelector('button');_x000D_
_x000D_
button.addEventListener('click', () => {_x000D_
  button.ariaExpanded = !JSON.parse(button.ariaExpanded);_x000D_
})

button[aria-expanded="true"] {_x000D_
  color: red;_x000D_
}

<button type="button" aria-expanded="false">Click me!</button>

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

commons-dbcp-1.1-RC2.jar

or any version of that..!!!!

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

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

floor a;
floor b;
a = -0.340515;

so what to do?

b = 65565 +a;
a = 65565 -b;

or

if(a < 0){
a = 65565-(65565+a);}

This maybe irrelevant and of no use, but as it's javascript, you don't have to use the ternary as suggested above in the ng-click statement. You should also be able to use the lazy evaluation ("or die") syntax as well. So for your example above:

<input  ng-click="{{if(profileForm.$valid) updateMyProfile()}}" name="submit" id="submit" value="Save" class="submit" type="submit">

would become:

<input  ng-click="profileForm.$valid && updateMyProfile()" name="submit" id="submit" value="Save" class="submit" type="submit">

In this case, if the profile is not valid then nothing happens, otherwise, updateMyProfile() is called. Like in the link @falinsky provides above.

Use a regex literal with the g modifier, and escape the forward slash with a backslash so it doesn't clash with the delimiters.

var str = 'some // slashes', replacement = '';
var replaced = str.replace(/\//g, replacement);

You can use MSSQL Server Auditing feature. From version SQL Server 2012 you will find this feature in all editions:

As of bootstrap 4, the answer is to simply set navbar-dark in the nav element, which will set the text and links to a light theme .

<nav class="navbar navbar-dark">

You are trying to decode an object that is already decoded. You have a str, there is no need to decode from UTF-8 anymore.

Simply drop the .decode('utf-8') part:

header_data = data[1][0][1]

As for your fetch() call, you are explicitly asking for just the first message. Use a range if you want to retrieve more messages. See the documentation:

The message_set options to commands below is a string specifying one or more messages to be acted upon. It may be a simple message number ('1'), a range of message numbers ('2:4'), or a group of non-contiguous ranges separated by commas ('1:3,6:9'). A range can contain an asterisk to indicate an infinite upper bound ('3:*').

Google guides me here but it didn't fix mine, this is a very general question and there are various causes, so I post my problem and solution here for reference in case anyone might read this later.

Another possible cause of 500 error is syntax error in header(...) function, like this one:

header($_SERVER['SERVER_PROTOCOL'] . '200 OK');

Be aware there should be space between server protocol and status code, so it should be:

header($_SERVER['SERVER_PROTOCOL'] . ' 200 OK');

So I suggest check your http header call if you have it in your code.

HTTParty makes this a bit easier I think (and works with nested json etc, which didn't seem to work in other examples I've seen.

require 'httparty'
HTTParty.post("http://localhost:3000/api/v1/users", body: {user: {email: '[email protected]', password: 'secret'}}).body

You forgot to mention the name of your database (is it "my"?).

ALTER DATABASE my SET SINGLE_USER WITH ROLLBACK IMMEDIATE;

ALTER DATABASE my SET OFFLINE;

ALTER DATABASE my MODIFY FILE 
(
   Name = my_Data,
   Filename = 'D:\DATA\my.MDF'
);

ALTER DATABASE my MODIFY FILE 
(
   Name = my_Log, 
   Filename = 'D:\DATA\my_1.LDF'
);

Now here you must manually move the files from their current location to D:\Data\ (and remember to rename them manually if you changed them in the MODIFY FILE command) ... then you can bring the database back online:

ALTER DATABASE my SET ONLINE;

ALTER DATABASE my SET MULTI_USER;

This assumes that the SQL Server service account has sufficient privileges on the D:\Data\ folder. If not you will receive errors at the SET ONLINE command.

you cannot access array (php array) from js try

<?php
$array = array(1,2,3,4,5,6);
echo json_encode($array);
?>

and js

$(document).ready( function() {
    $('#prev').click(function() {
        $.ajax({
            type: 'POST',
            url: 'ajax.php',
            data: 'id=testdata',
            dataType: 'json',
            cache: false,
            success: function(result) {
                $('#content1').html(result[0]);
            },
        });
    });
});

Maybe like this:

list('abcdefgh') # ['a', 'b', 'c', 'd', 'e', 'f', 'g', 'h']

For Windows there's a couple of tricks to take care of...

(Assuming you've installed MySQL from Oracle's site but maybe have chosen not to run the service at startup)...

1. To use "mysqld stop" from the command line for WinVista/Win7 you must right click on Start -> All Programs -> Accessories -> Command Prompt -> Run As Administrator

2. Now that you have local OS admin access you can use "mysqld stop" (which will simply return)

Implementation

1. Install brew

Follow the instructions at https://brew.sh/

2. Install the coreutils package

brew install coreutils

3. Create an Alias

You can place your alias in ~/.bashrc, ~/.bash_profile, or wherever you are used to keeping your bash aliases. I personally keep mine in ~/.bashrc

alias readlink=greadlink

You can create similar aliases for other coreutils such as gmv, gdu, gdf, and so on. But beware that the GNU behavior on a mac machine may be confusing to others used to working with native coreutils, or may behave in unexpected ways on your mac system.

Explanation

coreutils is a brew package that installs GNU/Linux core utilities which correspond to the Mac OSX implementation of them so that you can use those

You may find programs or utilties on your mac osx system which seem similar to Linux coreutils ("Core Utilities") yet they differ in some ways (such as having different flags).

This is because the Mac OSX implementation of these tools are different. To get the original GNU/Linux-like behavior you can install the coreutils package via the brew package management system.

This will install corresponding core utilities, prefixed by g. E.g. for readlink, you will find a corresponding greadlink program.

In order to make readlink perform like the GNU readlink (greadlink) implementation, you can make a simple alias after you install coreutils.

The documentation says:

When you need to set attributes that are also mapped to a JavaScript dot-property (such as href, style, src or event-handlers), favour that mapping instead.

So, just change id, value assignment and you should be done.

I like using a list comprehension in this case:

>>> [w for w in dir() if w == 'datetime' or w == 'sqlite3']
['datetime', 'sqlite3']

# To count modules of interest...
>>> count = [w for w in dir() if w == 'datetime' or w == 'sqlite3']
>>> len(count)
2

# To count all installed modules...
>>> count = dir()
>>> len(count)

Use onclick="this.value=''":

<input name="Name" value="Enter Your Name" onclick="this.value=''">

Actually, I believe you want to use the __getattr__ special method instead.

Quote from the Python docs:

__getattr__( self, name)

Called when an attribute lookup has not found the attribute in the usual places (i.e. it is not an instance attribute nor is it found in the class tree for self). name is the attribute name. This method should return the (computed) attribute value or raise an AttributeError exception.
Note that if the attribute is found through the normal mechanism, __getattr__() is not called. (This is an intentional asymmetry between __getattr__() and __setattr__().) This is done both for efficiency reasons and because otherwise __setattr__() would have no way to access other attributes of the instance. Note that at least for instance variables, you can fake total control by not inserting any values in the instance attribute dictionary (but instead inserting them in another object). See the __getattribute__() method below for a way to actually get total control in new-style classes.

Note: for this to work, the instance should not have a test attribute, so the line self.test=20 should be removed.

You could also just call to_a after each_byte or even better String#bytes

=> 'hello world'.each_byte.to_a
=> [104, 101, 108, 108, 111, 32, 119, 111, 114, 108, 100]

=> 'hello world'.bytes
=> [104, 101, 108, 108, 111, 32, 119, 111, 114, 108, 100]

Notes:

Avoid using require_once because it is slow: Why is require_once so bad to use?

You really should use an established library, such as Newtonsoft.Json (which even Microsoft uses for frameworks such as MVC and WebAPI), or .NET's built-in JavascriptSerializer.

Here's a sample of reading JSON using Newtonsoft.Json:

JObject o1 = JObject.Parse(File.ReadAllText(@"c:\videogames.json"));

// read JSON directly from a file
using (StreamReader file = File.OpenText(@"c:\videogames.json"))
using (JsonTextReader reader = new JsonTextReader(file))
{
  JObject o2 = (JObject) JToken.ReadFrom(reader);
}

If you return a serializable object, WebAPI will automatically send JSON or XML based on the Accept header that your client sends.

If you return a string, you'll get a string.

Compact solution (provided you don't need other environment variables):

call('sqsub -np {} /homedir/anotherdir/executable'.format(var1).split(),
      env=dict(LD_LIBRARY_PATH=my_path))

Using the env command line tool:

call('env LD_LIBRARY_PATH=my_path sqsub -np {} /homedir/anotherdir/executable'.format(var1).split())

Comprehensions are usually faster, and this has the advantage of not editing mydict during the iteration:

mydict = dict((k, v if v else '') for k, v in mydict.items())

Just use the formula

=A8*60*24

It appears the default setting for Adobe Reader X is for the toolbars not to be shown by default unless they are explicitly turned on by the user. And even when I turn them back on during a session, they don't show up automatically next time. As such, I suspect you have a preference set contrary to the default.

The state you desire, with the top and left toolbars not shown, is called "Read Mode". If you right-click on the document itself, and then click "Page Display Preferences" in the context menu that is shown, you'll be presented with the Adobe Reader Preferences dialog. (This is the same dialog you can access by opening the Adobe Reader application, and selecting "Preferences" from the "Edit" menu.) In the list shown in the left-hand column of the Preferences dialog, select "Internet". Finally, on the right, ensure that you have the "Display in Read Mode by default" box checked:

You can also turn off the toolbars temporarily by clicking the button at the right of the top toolbar that depicts arrows pointing to opposing corners:

Finally, if you have "Display in Read Mode by default" turned off, but want to instruct the page you're loading not to display the toolbars (i.e., override the user's current preferences), you can append the following to the URL:

#toolbar=0&navpanes=0

So, for example, the following code will disable both the top toolbar (called "toolbar") and the left-hand toolbar (called "navpane"). However, if the user knows the keyboard combination (F8, and perhaps other methods as well), they will still be able to turn them back on.

string url = @"http://www.domain.com/file.pdf#toolbar=0&navpanes=0";
this._WebBrowser.Navigate(url);

Here's some easy way to get slice of the map-keys.

// Return keys of the given map
func Keys(m map[string]interface{}) (keys []string) {
    for k := range m {
        keys = append(keys, k)
    }
    return keys
}

// use `Keys` func
func main() {
    m := map[string]interface{}{
        "foo": 1,
        "bar": true,
        "baz": "baz",
    }
    fmt.Println(Keys(m)) // [foo bar baz]
}

Python 2.7 and 3 can co-exist.
Python version shows on terminal is 2.7, but you can invoke it using "python3", see this:

Type "help", "copyright", "credits" or "license" for more information.

Your piece of script works just great. Are you sure you are not assigning anything else before the if to "i"?

A common mistake is also not to leave a space after and before the square brackets.

Brief Description

1. The answer from Brian Ramsay is more convenient if you only want to convert to minutes.
2. If you want Cocoa API do it for you and convert your NSTimeInterval not only to minutes but also to days, months, week, etc,... I think this is a more generic approach

3. Use NSCalendar method:

   • (NSDateComponents *)components:(NSUInteger)unitFlags fromDate:(NSDate *)startingDate toDate:(NSDate *)resultDate options:(NSUInteger)opts

   • "Returns, as an NSDateComponents object using specified components, the difference between two supplied dates". From the API documentation.

4. Create 2 NSDate whose difference is the NSTimeInterval you want to convert. (If your NSTimeInterval comes from comparing 2 NSDate you don't need to do this step, and you don't even need the NSTimeInterval).

5. Get your quotes from NSDateComponents

Sample Code

// The time interval 
NSTimeInterval theTimeInterval = 326.4;

// Get the system calendar
NSCalendar *sysCalendar = [NSCalendar currentCalendar];

// Create the NSDates
NSDate *date1 = [[NSDate alloc] init];
NSDate *date2 = [[NSDate alloc] initWithTimeInterval:theTimeInterval sinceDate:date1];

• Too much for just a conversion, you are right, but that's how the API works.
• My suggestion: if you get used to manage your time data using NSDate and NSCalendar, the API will do the hard work for you.

WScript.exe exists in two versions, one in C:\Windows\System32\ and the other in C:\Windows\SysWOW64\ directories. They run respectively in 64 bits and 32 bits (against immediate logic but true).

You may add the following code at the beginning of your script so that it automatically starts again in 32 bits if it detects that it's called in 64 bits.

Note that it transmits the arguments if it calls itself to switch to 64 bits.

' C:\Windows\System32\WScript.exe = WScript.exe
Dim ScriptHost : ScriptHost = Mid(WScript.FullName, InStrRev(WScript.FullName, "\") + 1, Len(WScript.FullName))

Dim oWs : Set oWs = CreateObject("WScript.Shell")
Dim oProcEnv : Set oProcEnv = oWs.Environment("Process")

' Am I running 64-bit version of WScript.exe/Cscript.exe? So, call script again in x86 script host and then exit.
If InStr(LCase(WScript.FullName), LCase(oProcEnv("windir") & "\System32\")) And oProcEnv("PROCESSOR_ARCHITECTURE") = "AMD64" Then
    ' rebuild arguments
    If Not WScript.Arguments.Count = 0 Then
        Dim sArg, Arg
        sArg = ""
        For Each Arg In Wscript.Arguments
              sArg = sArg & " " & """" & Arg & """"
        Next
    End If

    Dim sCmd : sCmd = """" &  oProcEnv("windir") & "\SysWOW64\" & ScriptHost & """" & " """ & WScript.ScriptFullName & """" & sArg
    'WScript.Echo "Call " & sCmd
    oWs.Run sCmd
    WScript.Quit
End If

$scope.$watch('age + name', function () {
  //called when name or age changed
});

Here function will get called when both age and name value get changed.

the Dictionary class implements ISerializable. The definition of Class Dictionary given below.

[DebuggerTypeProxy(typeof(Mscorlib_DictionaryDebugView<,>))]
[DebuggerDisplay("Count = {Count}")]
[Serializable]
[System.Runtime.InteropServices.ComVisible(false)]
public class Dictionary<TKey,TValue>: IDictionary<TKey,TValue>, IDictionary, IReadOnlyDictionary<TKey, TValue>, ISerializable, IDeserializationCallback  

I don't think that is the problem. refer to the below link, which says that if you are having any other data type which is not serializable then Dictionary will not be serialized. http://forums.asp.net/t/1734187.aspx?Is+Dictionary+serializable+

The Log class:

API for sending log output.

Generally, use the Log.v() Log.d() Log.i() Log.w() and Log.e() methods.

The order in terms of verbosity, from least to most is ERROR, WARN, INFO, DEBUG, VERBOSE. Verbose should never be compiled into an application except during development. Debug logs are compiled in but stripped at runtime. Error, warning and info logs are always kept.

Outside of Android, System.out.println(String msg) is used.

I have the same warning (it's make my app cannot build). When I add C function in Objective-C's .m file, But forgot to declared it at .h file.

I wondered if it would be possible to avoid some of the disadvantages of using global variables (see e.g. http://wiki.c2.com/?GlobalVariablesAreBad) by using a class namespace rather than a global/module namespace to pass values of variables. The following code indicates that the two methods are essentially identical. There is a slight advantage in using class namespaces as explained below.

The following code fragments also show that attributes or variables may be dynamically created and deleted in both global/module namespaces and class namespaces.

wall.py

# Note no definition of global variables

class router:
    """ Empty class """

I call this module 'wall' since it is used to bounce variables off of. It will act as a space to temporarily define global variables and class-wide attributes of the empty class 'router'.

source.py

import wall
def sourcefn():
    msg = 'Hello world!'
    wall.msg = msg
    wall.router.msg = msg

This module imports wall and defines a single function sourcefn which defines a message and emits it by two different mechanisms, one via globals and one via the router function. Note that the variables wall.msg and wall.router.message are defined here for the first time in their respective namespaces.

dest.py

import wall
def destfn():

    if hasattr(wall, 'msg'):
        print 'global: ' + wall.msg
        del wall.msg
    else:
        print 'global: ' + 'no message'

    if hasattr(wall.router, 'msg'):
        print 'router: ' + wall.router.msg
        del wall.router.msg
    else:
        print 'router: ' + 'no message'

This module defines a function destfn which uses the two different mechanisms to receive the messages emitted by source. It allows for the possibility that the variable 'msg' may not exist. destfn also deletes the variables once they have been displayed.

main.py

import source, dest

source.sourcefn()

dest.destfn() # variables deleted after this call
dest.destfn()

This module calls the previously defined functions in sequence. After the first call to dest.destfn the variables wall.msg and wall.router.msg no longer exist.

The output from the program is:

global: Hello world!
router: Hello world!
global: no message
router: no message

The above code fragments show that the module/global and the class/class variable mechanisms are essentially identical.

If a lot of variables are to be shared, namespace pollution can be managed either by using several wall-type modules, e.g. wall1, wall2 etc. or by defining several router-type classes in a single file. The latter is slightly tidier, so perhaps represents a marginal advantage for use of the class-variable mechanism.

There was an issue posted here about this: https://github.com/twbs/bootstrap/issues/14107

The issue was solved by this commit: https://github.com/twbs/bootstrap/commit/bd292ca3b89da982abf34473318c77ace3417fb5

The solution therefore is to override it back to #999 and not white as suggested (and also overriding all bootstraps styles, not just for webkit-styles):

.form-control::-moz-placeholder {
  color: #999;
}
.form-control:-ms-input-placeholder {
  color: #999;
}
.form-control::-webkit-input-placeholder {
  color: #999;
}

You can also do something like that:

<error-page>
    <error-code>403</error-code>
    <location>/403.html</location>
</error-page>

<error-page>
    <location>/error.html</location>
</error-page>

For error code 403 it will return the page 403.html, and for any other error code it will return the page error.html.

you need to call the function like this

$this->assign()

instead of just assign()

Another solution might look like this,

char arr[] = "mom";
std::cout << "hi " << std::string(arr);

which avoids using an extra variable.

This is about as late compared to the guy who said he was late as he was to the original answer, but in my case (MySQL via WAMP on Windows 7), I had to use:

I might be misunderstanding your question, so apologies if I am.

If you're looking for the words "Quid", "Application Number", etc. to be bold, just wrap them in <strong> tags:

Just call moment as a function without any arguments:

moment()

For timezone information with moment, look at the moment-timezone package: http://momentjs.com/timezone/

var a = A.parentNode.replaceChild(document.createElement("span"), A);

a is the replaced A element.

-l (that's a lower-case L).

The settings you need are "Local echo" and "Line editing" under the "Terminal" category on the left.

To get the characters to display on the screen as you enter them, set "Local echo" to "Force on".

To get the terminal to not send the command until you press Enter, set "Local line editing" to "Force on".

Explanation:

From the PuTTY User Manual (Found by clicking on the "Help" button in PuTTY):

4.3.8 ‘Local echo’

With local echo disabled, characters you type into the PuTTY window are not echoed in the window by PuTTY. They are simply sent to the server. (The server might choose to echo them back to you; this can't be controlled from the PuTTY control panel.)

Some types of session need local echo, and many do not. In its default mode, PuTTY will automatically attempt to deduce whether or not local echo is appropriate for the session you are working in. If you find it has made the wrong decision, you can use this configuration option to override its choice: you can force local echo to be turned on, or force it to be turned off, instead of relying on the automatic detection.

4.3.9 ‘Local line editing’ Normally, every character you type into the PuTTY window is sent immediately to the server the moment you type it.

If you enable local line editing, this changes. PuTTY will let you edit a whole line at a time locally, and the line will only be sent to the server when you press Return. If you make a mistake, you can use the Backspace key to correct it before you press Return, and the server will never see the mistake.

Since it is hard to edit a line locally without being able to see it, local line editing is mostly used in conjunction with local echo (section 4.3.8). This makes it ideal for use in raw mode or when connecting to MUDs or talkers. (Although some more advanced MUDs do occasionally turn local line editing on and turn local echo off, in order to accept a password from the user.)

Some types of session need local line editing, and many do not. In its default mode, PuTTY will automatically attempt to deduce whether or not local line editing is appropriate for the session you are working in. If you find it has made the wrong decision, you can use this configuration option to override its choice: you can force local line editing to be turned on, or force it to be turned off, instead of relying on the automatic detection.

Putty sometimes makes wrong choices when "Auto" is enabled for these options because it tries to detect the connection configuration. Applied to serial line, this is a bit trickier to do.

• Open Terminal.
• Go to Edit -> Profile Preferences.
• Select the Title & command Tab in the window opened.
• Mark the checkbox Run command as login shell.
• close the window and restart the Terminal.

Java 8: Use random generator isolated to the current thread: ThreadLocalRandom nextBoolean()

Like the global Random generator used by the Math class, a ThreadLocalRandom is initialized with an internally generated seed that may not otherwise be modified. When applicable, use of ThreadLocalRandom rather than shared Random objects in concurrent programs will typically encounter much less overhead and contention.

java.util.concurrent.ThreadLocalRandom.current().nextBoolean();

I had the same problem, I did the following

heroku run rails c

It identified a syntax error and missing comma within a controller permitted params. As mentioned above the Heroku logs did not provide sufficient information to problem solve the problem.

I have not seen the application crashed message on Heroku previously.

A better alternative is provided in ES6 using Sets. So, instead of declaring Arrays, it is recommended to use Sets if you need to have an array that shouldn't add duplicates.

var array = new Set();
array.add(1);
array.add(2);
array.add(3);

console.log(array);
// Prints: Set(3) {1, 2, 3}

array.add(2); // does not add any new element

console.log(array);
// Still Prints: Set(3) {1, 2, 3}

It's now builtin in MySQL 8.0 and MariaDB 10.2:

SELECT
  itemID, COUNT(*) as ordercount,
  ROW_NUMBER OVER (PARTITION BY itemID ORDER BY rank DESC) as rank
FROM orders
GROUP BY itemID ORDER BY rank DESC

As already pointed out in comments by Abhijeet you can just add line like:

/target/**

to exclude file in \.git\info\ folder.

Then if you want to get rid of that target folder in your remote repo you will need to first manually delete this folder from your local repository, commit and then push it. Thats because git will show you content of a target folder as modified at first.

Your interface exposes the concrete HttpClient class, therefore any classes that use this interface are tied to it, this means that it cannot be mocked.

HttpClient does not inherit from any interface so you will have to write your own. I suggest a decorator-like pattern:

public interface IHttpHandler
{
    HttpResponseMessage Get(string url);
    HttpResponseMessage Post(string url, HttpContent content);
    Task<HttpResponseMessage> GetAsync(string url);
    Task<HttpResponseMessage> PostAsync(string url, HttpContent content);
}

And your class will look like this:

public class HttpClientHandler : IHttpHandler
{
    private HttpClient _client = new HttpClient();

    public HttpResponseMessage Get(string url)
    {
        return GetAsync(url).Result;
    }

    public HttpResponseMessage Post(string url, HttpContent content)
    {
        return PostAsync(url, content).Result;
    }

    public async Task<HttpResponseMessage> GetAsync(string url)
    {
        return await _client.GetAsync(url);
    }

    public async Task<HttpResponseMessage> PostAsync(string url, HttpContent content)
    {
        return await _client.PostAsync(url, content);
    }
}

The point in all of this is that HttpClientHandler creates its own HttpClient, you could then of course create multiple classes that implement IHttpHandler in different ways.

The main issue with this approach is that you are effectively writing a class that just calls methods in another class, however you could create a class that inherits from HttpClient (See Nkosi's example, it's a much better approach than mine). Life would be much easier if HttpClient had an interface that you could mock, unfortunately it does not.

This example is not the golden ticket however. IHttpHandler still relies on HttpResponseMessage, which belongs to System.Net.Http namespace, therefore if you do need other implementations other than HttpClient, you will have to perform some kind of mapping to convert their responses into HttpResponseMessage objects. This of course is only a problem if you need to use multiple implementations of IHttpHandler but it doesn't look like you do so it's not the end of the world, but it's something to think about.

Anyway, you can simply mock IHttpHandler without having to worry about the concrete HttpClient class as it has been abstracted away.

I recommend testing the non-async methods, as these still call the asynchronous methods but without the hassle of having to worry about unit testing asynchronous methods, see here

You can use :

var MSIE = jQuery.support.leadingWhitespace; // This property is not supported by ie 6-8

$(document).ready(function(){

if (MSIE){
    if (navigator.vendor == 'Apple Computer, Inc.'){
        // some code for this navigator
    } else {
       // some code for others browsers
    }

} else {
    // default code

}});

I adapted @shareef's answer to make it concise. I use,

.sort(function(arg1, arg2) { return arg1.length - arg2.length })

I believe tuple() takes a list as an argument For example,

tuple([1,2,3]) # returns (1,2,3)

see what happens if you wrap your array with brackets

background:rgba(0,0,0,0);
opacity:1;

To export user variables, open a command prompt and use regedit with /e

Example :

regedit /e "%userprofile%\Desktop\my_user_env_variables.reg" "HKEY_CURRENT_USER\Environment"

I would recommend NOT to use global / window / eval for this purpose.
Instead, do it this way:

define all methods as properties of Handler:

var Handler={};

Handler.application_run = function (name) {
console.log(name)
}

Now call it like this

var somefunc = "application_run";
Handler[somefunc]('jerry');

Output: jerry

Case when importing functions from different files

import { func1, func2 } from "../utility";

const Handler= {
  func1,
  func2
};

Handler["func1"]("sic mundus");
Handler["func2"]("creatus est");

You can use the maven.javadoc.skip property to skip execution of the plugin, going by the Mojo's javadoc. You can specify the value as a Maven property:

<properties>
    <maven.javadoc.skip>true</maven.javadoc.skip>
</properties>

or as a command-line argument: -Dmaven.javadoc.skip=true, to skip generation of the Javadocs.

Below Command where project is a folder which contains package.json file

npm run --prefix project ${COMMAND}

is working as well. Useful in Docker based applications.

I think the new preferred way might be to use IDataErrorInfo

You want urlparse using python2:

from urlparse import urlparse

import sys
filename = sys.argv[1]
source = open(filename, 'r').read() + '\n'
compile(source, filename, 'exec')

Save this as checker.py and run python checker.py yourpyfile.py.

You should use some aggregate function to get the value of AnotherColumn that you want. That is, if you want the lowest value of AnotherColumn for each value of SomeColumn (either numerically or lexicographically), you can use:

SELECT SomeColumn, MIN(AnotherColumn)
FROM YourTable
GROUP BY SomeColumn

Problem Cause : The process of the current program is still running without interuption. (This is the reason why you haven't got this issue after a restart)

The fix is simple : Go to cmd and type the command taskkill -im process-name.exe -f

Eg:

 taskkill -im demo.exe -f

here,

demo - is my program name

If you want to call a function of base class from its derived class you can simply call inside the overridden function with mentioning base class name(like Foo::printStuff()).

code goes here

#include <iostream>
using namespace std;

class Foo
{
public:
    int x;

    virtual void printStuff()
    {
         cout<<"Base Foo printStuff called"<<endl;
    }
};

class Bar : public Foo
{
public:
    int y;

    void printStuff()
    {
        cout<<"derived Bar printStuff called"<<endl;
        Foo::printStuff();/////also called the base class method
    }
};

int main()
{
    Bar *b=new Bar;
    b->printStuff();
}

Again you can determine at runtime which function to call using the object of that class(derived or base).But this requires your function at base class must be marked as virtual.

code below

#include <iostream>
using namespace std;

class Foo
{
public:
    int x;

    virtual void printStuff()
    {
         cout<<"Base Foo printStuff called"<<endl;
    }
};

class Bar : public Foo
{
public:
    int y;

    void printStuff()
    {
        cout<<"derived Bar printStuff called"<<endl;
    }
};

int main()
{

    Foo *foo=new Foo;
    foo->printStuff();/////this call the base function
    foo=new Bar;
    foo->printStuff();
}

This is a generalization of the problem of "how do I find out how many bytes n bits will take? (A: (n bits + 7) / 8).

int RoundUp(int n, int roundTo)
{
    // fails on negative?  What does that mean?
    if (roundTo == 0) return 0;
    return ((n + roundTo - 1) / roundTo) * roundTo; // edit - fixed error
}

}];_x000D_
data.map((item, i) => console.log('Index:', i, 'Id:', item.id));

And to cover the cases when the property "id" is not present use filter:

var data = [{_x000D_
  "id": "1",_x000D_
  "msg": "hi",_x000D_
  "tid": "2013-05-05 23:35",_x000D_

  "id": "2",_x000D_

  "tid": "2013-05-05 23:45",_x000D_
  "fromWho": "[email protected]"_x000D_
}, {_x000D_
  "msg": "abcde",_x000D_
  "tid": "2013-06-06 23:46",_x000D_
  "fromWho": "[email protected]"_x000D_
}];_x000D_
_x000D_
data.filter(item=>item.hasOwnProperty('id'))_x000D_
                .map((item, i) => console.log('Index:', i, 'Id:', item.id));

Programmatic formatting solution:

The JSON.stringify method supported by many modern browsers (including IE8) can output a beautified JSON string:

JSON.stringify(jsObj, null, "\t"); // stringify with tabs inserted at each level
JSON.stringify(jsObj, null, 4);    // stringify with 4 spaces at each level

Demo: http://jsfiddle.net/AndyE/HZPVL/

This method is also included with json2.js, for supporting older browsers.

Manual formatting solution

If you don't need to do it programmatically, Try JSON Lint. Not only will it prettify your JSON, it will validate it at the same time.

$day_number = date('N', $date);

This will return a 1 for Monday to 7 for Sunday, for the date that is stored in $date. Omitting the second argument will cause date() to return the number for the current day.

As @Felix Kling suggested use action='store_true':

>>> from argparse import ArgumentParser
>>> p = ArgumentParser()
>>> _ = p.add_argument('-f', '--foo', action='store_true')
>>> args = p.parse_args()
>>> args.foo
False
>>> args = p.parse_args(['-f'])
>>> args.foo
True

Tables are not meant for this, why don't you use <div>'s and CSS?

I would probably use $('.mydiv').is('#foo'); That said if you know the Id why wouldnt you just apply it to the selector in the first place?

It all depends what type of operation you are doing while iterating , all data structures have trade off between time and memory and depending on our needs we should choose the right DS. So there are some cases where LinkedList are faster then array and vice versa . Consider the three basic operation on data structures.

• Searching

Since array is index based data structure searching array.get(index) will take O(1) time while linkedlist is not index DS so you will need to traverse up to index , where index <=n , n is size of linked list , so array is faster the linked list when have random access of elements.

Q.So what's the beauty behind this ?

As Arrays are contiguous memory blocks, large chunks of them will be loaded into the cache upon first access this makes it comparatively quick to access remaining elements of the array,as much as we access the elements in array locality of reference also increases thus less catch misses, Cache locality refers to the operations being in the cache and thus execute much faster as compared to in memory,basically In array we maximize the chances of sequential element access being in the cache. While Linked lists aren't necessarily in contiguous blocks of memory, there's no guarantee that items which appear sequentially in the list are actually arranged near each-other in memory, this means fewer cache hits e.g. more cache misses because we need to read from memory for every access of linked list element which increases the time it takes to access them and degraded performance so if we are doing more random access operation aka searching , array will be fast as explained below.

• Insertion

This is easy and fast in LinkedList as insertion is O(1) operation in LinkedList (in Java) as compared to array, consider the case when array is full, we need to copy contents to new array if array gets full which makes inserting an element into ArrayList of O(n) in worst case, while ArrayList also needs to update its index if you insert something anywhere except at the end of array , in case of linked list we needn't to be resize it, you just need to update pointers.

• Deletion

It works like insertions and better in LinkedList than array.

This may not help answer your question directly but is something I have found useful when trying to work with dynamic ranges that may help you out.

Suppose in your worksheet you have the numbers 100 to 108 in cells A1:C3:

          A    B    C  
1        100  101  102
2        103  104  105
3        106  107  108

Then to select all the cells you can use the CurrentRegion property:

Sub SelectRange()
Dim dynamicRange As Range

Set dynamicRange = Range("A1").CurrentRegion

End Sub

The advantage of this is that if you add new rows or columns to your block of numbers (e.g. 109, 110, 111) then the CurrentRegion will always reference the enlarged range (in this case A1:C4).

I have used CurrentRegion quite a bit in my VBA code and find it is most useful when working with dynmacially sized ranges. Also it avoids having to hard code ranges in your code.

As a final note, in my code you will see that I used A1 as the reference cell for CurrentRegion. It will also work no matter which cell you reference (try: replacing A1 with B2 for example). The reason is that CurrentRegion will select all contiguous cells based on the reference cell.

Solution 1: Copy any text

HTML

<button (click)="copyMessage('This goes to Clipboard')" value="click to copy" >Copy this</button>

.ts file

copyMessage(val: string){
    const selBox = document.createElement('textarea');
    selBox.style.position = 'fixed';
    selBox.style.left = '0';
    selBox.style.top = '0';
    selBox.style.opacity = '0';
    selBox.value = val;
    document.body.appendChild(selBox);
    selBox.focus();
    selBox.select();
    document.execCommand('copy');
    document.body.removeChild(selBox);
  }

Solution 2: Copy from a TextBox

HTML

 <input type="text" value="User input Text to copy" #userinput>
      <button (click)="copyInputMessage(userinput)" value="click to copy" >Copy from Textbox</button>

.ts file

    /* To copy Text from Textbox */
  copyInputMessage(inputElement){
    inputElement.select();
    document.execCommand('copy');
    inputElement.setSelectionRange(0, 0);
  }

Solution 3: Import a 3rd party directive ngx-clipboard

<button class="btn btn-default" type="button" ngxClipboard [cbContent]="Text to be copied">copy</button>

Solution 4: Custom Directive

If you prefer using a custom directive, Check Dan Dohotaru's answer which is an elegant solution implemented using ClipboardEvent.

Solution 5: Angular Material

Angular material 9 + users can utilize the built-in clipboard feature to copy text. There are a few more customization available such as limiting the number of attempts to copy data.

Thanks to "msoliman" for his hint, however his answer doesn't give clear solution for those who doesn't have VS2010
For example I have VS2012 and VS2013 and there are no such KEYs in system registry.

Solution:
Edit file: "[Python_install_loc]/Lib/distutils/msvc9compiler.py"
Change on line 224:

productdir = Reg.get_value(r"%s\Setup\VC" % vsbase,
                               "productdir")

to:

productdir = "C:\Program Files (x86)\Microsoft Visual Studio [your_vs_version(11/12...)]\VC"

and that should work

no need for the padding or the corners.

here's a sample:

<shape xmlns:android="http://schemas.android.com/apk/res/android" android:shape="oval" >
    <gradient android:startColor="#FFFF0000" android:endColor="#80FF00FF"
        android:angle="270"/>
</shape>

based on :

https://stackoverflow.com/a/10104037/878126

if you don't like the double brackets or you don't want to write a function, you can just use a variable.

$path = Test-Path C:\Code
if (!$path) {
    write "it doesn't exist!"
}

Another edge-case EF Core scenario.

Check you have a Migrations/YOURNAMEContextModelSnapshot.cs file.

as detailed in - https://docs.microsoft.com/en-us/ef/core/managing-schemas/migrations/#create-a-migration

If you have tried to manually re-create your database by deleting migration.cs files, be careful that your Migrations/*ContextModelSnapshot.cs file still exists.

Without it, your subsequent migrations have no snapshot on which to create the required differences and your new migrations files will look like they are re-creating everything again from scratch, you will then get the existing table error as above.

Your task declaration is incorrectly combining the Copy task type and project.copy method, resulting in a task that has nothing to copy and thus never runs. Besides, Copy isn't the right choice for renaming a directory. There is no Gradle API for renaming, but a bit of Groovy code (leveraging Java's File API) will do. Assuming Project1 is the project directory:

task renABCToXYZ {     doLast {         file("ABC").renameTo(file("XYZ"))     } } 

Looking at the bigger picture, it's probably better to add the renaming logic (i.e. the doLast task action) to the task that produces ABC.

Using java-7 nio api, calculating the folder size can be done a lot quicker.

Here is a ready to run example that is robust and won't throw an exception. It will log directories it can't enter or had trouble traversing. Symlinks are ignored, and concurrent modification of the directory won't cause more trouble than necessary.

/**
 * Attempts to calculate the size of a file or directory.
 * 
 * <p>
 * Since the operation is non-atomic, the returned value may be inaccurate.
 * However, this method is quick and does its best.
 */
public static long size(Path path) {

    final AtomicLong size = new AtomicLong(0);

    try {
        Files.walkFileTree(path, new SimpleFileVisitor<Path>() {
            @Override
            public FileVisitResult visitFile(Path file, BasicFileAttributes attrs) {

                size.addAndGet(attrs.size());
                return FileVisitResult.CONTINUE;
            }

            @Override
            public FileVisitResult visitFileFailed(Path file, IOException exc) {

                System.out.println("skipped: " + file + " (" + exc + ")");
                // Skip folders that can't be traversed
                return FileVisitResult.CONTINUE;
            }

            @Override
            public FileVisitResult postVisitDirectory(Path dir, IOException exc) {

                if (exc != null)
                    System.out.println("had trouble traversing: " + dir + " (" + exc + ")");
                // Ignore errors traversing a folder
                return FileVisitResult.CONTINUE;
            }
        });
    } catch (IOException e) {
        throw new AssertionError("walkFileTree will not throw IOException if the FileVisitor does not");
    }

    return size.get();
}

In Pyspark, to run local spark application using Pycharm use below lines

os.environ['HADOOP_HOME'] = "C:\\winutils"
print os.environ['HADOOP_HOME']

Try using absolute positioning, rather than relative positioning

this should get you close - you can adjust by tweaking margins or top/left positions

#play_button {
    position:absolute;
    transition: .5s ease;
    top: 50%;
    left: 50%;
}

We can use "postMessage" concept for sending data to an underlying iframe from main window.

you can checkout more about postMessage using this link add the below code inside main window page

// main window code
window.frames['myFrame'].contentWindow.postMessage("Hello World!");

we will pass "Hello World!" message to an iframe contentWindow with iframe id="myFrame".

now add the below code inside iframe source code

// iframe document code
function receive(event) {
    console.log("Received Message : " + event.data);
}
window.addEventListener('message', receive);

in iframe webpage we will attach an event listener to receive event and in 'receive' callback we will print the data to console

As of Maven Eclipse (m2e) version 0.12 all Maven life-cycle goals must map to an installed m2e extension. In this case, the maven-ear-plugin had an-unmapped goal default-generate-application-xml.

You can exclude un-mapped life-cycle goals by simply following the instructions here:

https://wiki.eclipse.org/M2E_plugin_execution_not_covered

Alternatively, simply right-click on the error message in Eclipse and choosing Quick Fix -> Ignore for every pom with such errors.

You should be careful when ignoring life-cycle goals: typically goals do something useful and if you configure them to be ignored in Eclipse you may miss important build steps. You might also want to consider adding support to the Maven Eclipse EAR extension for the unmapped life-cycle goal.

We can pretend they are filenames and remove extensions:

tools::file_path_sans_ext(a)
# [1] "NM_020506"    "NM_020519"    "NM_001030297" "NM_010281"    "NM_011419"    "NM_053155"

When I ran into this problem, it was a result of trying to use an inner class to serve as the DO. Construction of the inner class (silently) required an instance of the enclosing class -- which wasn't available to Jackson.

In this case, moving the inner class to its own .java file fixed the problem.

It's simple. Just add:

PictureBox1.BackgroundImageLayout = ImageLayout.Zoom;

Some receivers expect EOL sequence, which is typically two characters \r\n, so try in your code replace the line

unsigned char cmd[] = {'I', 'N', 'I', 'T', ' ', '\r', '\0'};

with

unsigned char cmd[] = "INIT\r\n";

BTW, the above way is probably more efficient. There is no need to quote every character.

You can change the background color of the <CheckBox> by embedding it inside a <LinearLayout>. Then change the background color of <LinearLayout> to the color you want.

Basically to find gcd and lcm on a set of numbers you can use below formula,

LCM(a, b) X HCF(a, b) = a * b

Meanwhile in java you can use euclid's algorithm to find gcd and lcm, like this

public static int GCF(int a, int b)
{
    if (b == 0)
    {
       return a;
    }
    else
    {
       return (GCF(b, a % b));
    }
}

You can refer this resource to find examples on euclid's algorithm.

I have done something similar to this. One approach is to interpolate over the animation time the height of the view over time inside the rows onMeasure while issuing requestLayout() for the listView. Yes it may be be better to do inside the listView code directly but it was a quick solution (that looked good!)

Well, what I do on every project is a mix of the options above.

First, add the jsr310 dependency:

<dependency>
    <groupId>com.fasterxml.jackson.datatype</groupId>
    <artifactId>jackson-datatype-jsr310</artifactId>
</dependency>

Important detail: put this dependency on the top of your depedencies list. I already see a project where the Localdate error persists even with this dependency on the pom.xml. But changing the order of the depedency the error was gone.

On your /src/main/resources/application.yml file, setup the write-dates-as-timestamps property:

spring:
  jackson:
    serialization:
      write-dates-as-timestamps: false

And create a ObjectMapper bean as this:

@Configuration
public class WebConfigurer {

    @Bean
    @Primary
    public ObjectMapper objectMapper(Jackson2ObjectMapperBuilder builder) {
        ObjectMapper objectMapper = builder.build();
        objectMapper.configure(SerializationFeature.WRITE_DATES_AS_TIMESTAMPS, false);
        return objectMapper;
    }

}

Following this configuration, the conversion always work on Spring Boot 1.5.x without any error.

Bonus: Spring AMQP Queue configuration

Working with Spring AMQP, pay attention if you have a new instance of Jackson2JsonMessageConverter (common thing when creating a SimpleRabbitListenerContainerFactory). You need to pass the ObjectMapper bean to it, like:

Jackson2JsonMessageConverter converter = new Jackson2JsonMessageConverter(objectMapper);

Otherwise, you will receive the same error.

select 1 from table

will return a column of 1's for every row in the table. You could use it with a where statement to check whether you have an entry for a given key, as in:

if exists(select 1 from table where some_column = 'some_value')

What your friend was probably saying is instead of making bulk selects with select * from table, you should specify the columns that you need precisely, for two reasons:

1) performance & you might retrieve more data than you actually need.

2) the query's user may rely on the order of columns. If your table gets updated, the client will receive columns in a different order than expected.

start both the services on the xampp control panel click shell enter: # mysql -h 127.0.0.1 -u root

that works just fine. Below is the logtrail:-

I've had good luck with XLConnect: http://cran.r-project.org/web/packages/XLConnect/index.html

Here is an answer that works with data.table and is simpler. This assumes your data.table is named yourDF:

j1 <- max.col(yourDF[, .(V1, V2, V3, V4)], "first")
yourDF$newCol <- c("V1", "V2", "V3", "V4")[j1]

Replace ("V1", "V2", "V3", "V4") and (V1, V2, V3, V4) with your column names

None of the above answers seemed to match my problem. My gpg binary (/usr/local/bin/gpg -> /usr/local/MacGPG2/bin/gpg2) was installed as part of GPG Suite, rather than by brew.

Nevertheless, I felt that the advice boiled down to: "use whichever gpg binary is the latest available on brew". So I tried:

brew update
brew upgrade git
brew install gpg

# the following are suggestions from brew's Caveats, to make `/usr/local/bin/gpg`
# point to the brew binary:
rm '/usr/local/bin/gpg'
brew link --overwrite gnupg2

I verified that I had correctly changed the gpg upon my $PATH to point to the new executable from brew:

 which gpg
/usr/local/bin/gpg
 ls -l /usr/local/bin/gpg
lrwxr-xr-x  1 burger  admin  33 Feb 13 13:22 /usr/local/bin/gpg -> ../Cellar/gnupg2/2.0.30_3/bin/gpg

And I also explicitly told git which gpg binary to use:

git config --global gpg.program gpg

Well, maybe that's not completely watertight, as it's sensitive to path. I didn't actually go as far as confirming beyond doubt that git had switched to invoking the brew gpg.

In any case: none of this was sufficient to make git commit successfully sign my commits again.

The thing that worked for me ultimately was to update GPG Suite. I was running version 2016.7, and I found that updating to 2016.10 fixed the problem for me.

I opened GPG Keychain.app, and hit "Check for updates…". With the new version: signed commits worked correctly again.

In NetBeans IDE 8.0 you can use a community contributed plugin https://github.com/tusharvjoshi/nbrunwithargs which will allow you to pass arguments while Run Project or Run Single File command.

For passing arguments to Run Project command either you have to set the arguments in the Project properties Run panel, or use the new command available after installing the plugin which says Run with Arguments

For passing command line arguments to a Java file having main method, just right click on the method and choose Run with Arguments command, of this plugin

UPDATE (24 mar 2014) This plugin is now available in NetBeans Plugin Portal that means it can be installed from Plugins dialog box from the available plugins shown from community contributed plugins, in NetBeans IDE 8.0

UPDATE

Microsoft now provide this artifact in maven central. See @nirmal's answer for further details: https://stackoverflow.com/a/41149866/1570834

ORIGINAL ANSWER

The issue is that Maven can't find this artifact in any of the configured maven repositories.

Unfortunately Microsoft doesn't make this artifact available via any maven repository. You need to download the jar from the Microsoft website, and then manually install it into your local maven repository.

You can do this with the following maven command:

mvn install:install-file -Dfile=sqljdbc4.jar -DgroupId=com.microsoft.sqlserver -DartifactId=sqljdbc4 -Dversion=4.0 -Dpackaging=jar

Then next time you run maven on your POM it will find the artifact.

I was just implementing this actual problem in my current project. i did it for all ajax-POSTs that needed an authenticated user.

First off i decided to hook my jquery ajax calls so i do not to repeat myself too often. this javascript snippet ensures all ajax (post) calls will add my request validation token to the request. Note: the name __RequestVerificationToken is used by the .Net framework so i can utilize the standard Anti-CSRF features as shown below.

$(document).ready(function () {
    var securityToken = $('[name=__RequestVerificationToken]').val();
    $('body').bind('ajaxSend', function (elm, xhr, s) {
        if (s.type == 'POST' && typeof securityToken != 'undefined') {
            if (s.data.length > 0) {
                s.data += "&__RequestVerificationToken=" + encodeURIComponent(securityToken);
            }
            else {
                s.data = "__RequestVerificationToken=" + encodeURIComponent(securityToken);
            }
        }
    });
});

In your Views where you need the token to be available to the above javascript just use the common HTML-Helper. You can basically add this code whereever you want. I placed it within a if(Request.IsAuthenticated) statement:

@Html.AntiForgeryToken() // you can provide a string as salt when needed which needs to match the one on the controller

In your controller simply use the standard ASP.Net MVC Anti-CSRF mechanism. I did it like this (though i actually used Salt).

[HttpPost]
[Authorize]
[ValidateAntiForgeryToken]
public JsonResult SomeMethod(string param)
{
    // do something
    return Json(true);
}

With Firebug or a similar tool you can easily see how your POST requests now have a __RequestVerificationToken parameter appended.

It works more or less like this (example using an image/jpg file):

async public Task<HttpResponseMessage> UploadImage(string url, byte[] ImageData)
{
    var requestContent = new MultipartFormDataContent(); 
    //    here you can specify boundary if you need---^
    var imageContent = new ByteArrayContent(ImageData);
    imageContent.Headers.ContentType = 
        MediaTypeHeaderValue.Parse("image/jpeg");

    requestContent.Add(imageContent, "image", "image.jpg");

    return await client.PostAsync(url, requestContent);
}

(You can requestContent.Add() whatever you want, take a look at the HttpContent descendant to see available types to pass in)

When completed, you'll find the response content inside HttpResponseMessage.Content that you can consume with HttpContent.ReadAs*Async.

In Kotlin:

val callback = requireActivity().onBackPressedDispatcher.addCallback(this) {
    // Handle the back button event
}

For more information you can check this.

There is also specific question about overriding back button in Kotlin.

Map.Entry is a key and its value combined into one class. This allows you to iterate over Map.entrySet() instead of having to iterate over Map.keySet(), then getting the value for each key. A better way to write what you have is:

for (Map.Entry<String, JButton> entry : listbouton.entrySet())
{
  String key = entry.getKey();
  JButton value = entry.getValue();

  this.add(value);
}

If this wasn't clear let me know and I'll amend my answer.

If you only want to change the current page address, you can do that by simply doing this in Javascript :

location.href = "http://www.example.com/test";

None of the methods worked for me as i needed to pull the image from a folder instead of adding it to the application. The below code worked:

TestImage.Source = GetImage("/Content/Images/test.png")

private static BitmapImage GetImage(string imageUri)
{
    var bitmapImage = new BitmapImage();
    
    bitmapImage.BeginInit();
    bitmapImage.UriSource = new Uri("pack://siteoforigin:,,,/" + imageUri,             UriKind.RelativeOrAbsolute);
    bitmapImage.EndInit();
    
    return bitmapImage;
} 

CodeIgniter file upload optionally ...works perfectly..... :)

---------- controller ---------

function file()
{
 $this->load->view('includes/template', $data);
}

function valid_file()
{
 $this->form_validation->set_rules('userfile', 'File', 'trim|xss_clean');

 if ($this->form_validation->run()==FALSE) 
 {
    $this->file();
 }
 else
 {
  $config['upload_path']   = './documents/';
  $config['allowed_types'] = 'gif|jpg|png|docx|doc|txt|rtf';
  $config['max_size']      = '1000';
  $config['max_width']     = '1024';
  $config['max_height']    = '768';

  $this->load->library('upload', $config);

  if ( !$this->upload->do_upload('userfile',FALSE))
  {
    $this->form_validation->set_message('checkdoc', $data['error'] = $this->upload->display_errors());

    if($_FILES['userfile']['error'] != 4)
    {
        return false;
    }

  }
  else
  {
    return true;
  }
}

i just use this lines which makes it optionally,

if($_FILES['userfile']['error'] != 4)
{
 return false;

$_FILES['userfile']['error'] != 4 is for file required to upload.

you can make it unnecessary by using $_FILES['userfile']['error'] != 4, then it will pass this error for file required and works great with other types of errors if any by using return false , hope it works for u ....

I think the only way to do this is to run another machine in parallel and use that machine to issue commands to your android box similar to how you would with a phone. If you have issues with the IP changing you can reserve an ip on your router and have the machine grab that one instead of asking the routers DHCP for one. This way you can ping the machine and figure out if it's done rebooting to continue the script.

This will work in Python 3

import urllib.request

user_agent = 'Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.9.0.7) Gecko/2009021910 Firefox/3.0.7'

url = "http://en.wikipedia.org/wiki/List_of_TCP_and_UDP_port_numbers"
headers={'User-Agent':user_agent,} 

request=urllib.request.Request(url,None,headers) #The assembled request
response = urllib.request.urlopen(request)
data = response.read() # The data u need

Remove this line from activity if you have added

 @Override
    protected void onPostCreate(Bundle savedInstanceState) {
        super.onPostCreate(savedInstanceState);
        // Sync the toggle state after onRestoreInstanceState has occurred.
        mDrawerToggle.syncState();
    }

Then set icon

 getSupportActionBar().setHomeAsUpIndicator(icon);

This way works fine for me:

var request = new RestSharp.RestRequest("RESOURCE", RestSharp.Method.POST) { RequestFormat = RestSharp.DataFormat.Json }
                .AddBody(BODY);

var response = Client.Execute(request);

// Handle response errors
HandleResponseErrors(response);

if (Errors.Length == 0)
{ }
else
{ }

Hope this helps! (Although it is a bit late)

I probably use github.com/bramstein/jsizes jquery plugin for paddings and margins in very comfortable way, Thanks...

I think this should work:

#include <time.h>

clock_t start = clock(), diff;
ProcessIntenseFunction();
diff = clock() - start;

int msec = diff * 1000 / CLOCKS_PER_SEC;
printf("Time taken %d seconds %d milliseconds", msec/1000, msec%1000);

[excel 2010] separate the date and time into separate columns and select both as X-Axis and data as graph series see http://www.79783.mrsite.com/USERIMAGES/horizontal_axis_date_and_time2.xlsx

That's a loop that says, okay, for every time that i is smaller than 8, I'm going to do whatever is in the code block. Whenever i reaches 8, I'll stop. After each iteration of the loop, it increments i by 1 (i++), so that the loop will eventually stop when it meets the i < 8 (i becomes 8, so no longer is smaller than) condition.

For example, this:

for (int i = 0; i < 8; i++)
{
   Console.WriteLine(i);
}

Will output: 01234567

See how the code was executed 8 times?

In terms of arrays, this can be helpful when you don't know the size of the array, but you want to operate on every item of it. You can do:

Disclaimer: This following code will vary dependent upon language, but the principle remains the same

Array yourArray;

for (int i = 0; i < yourArray.Count; i++)
{
    Console.WriteLine(yourArray[i]);
}

The difference here is the number of execution times is entirely dependent on the size of the array, so it's dynamic.

https://stackoverflow.com/a/9824943/14731 contains a better answer (one that is more readable and works with set -o nounset enabled). It works roughly like this:

if [ -n "${VAR-}" ]; then
    echo "VAR is set and is not empty"
elif [ "${VAR+DEFINED_BUT_EMPTY}" = "DEFINED_BUT_EMPTY" ]; then
    echo "VAR is set, but empty"
else
    echo "VAR is not set"
fi

Here is the simplest solution ever:

You can add onPressOut event to the TouchableOpcaity and do whatever you want to do. It will not let user to press again until onPressOut is done

TLDR:

git pull is like running git fetch then git merge
git pull --rebase is like git fetch then git rebase

In reply to your first statement,

git pull is like a git fetch + git merge.

"In its default mode, git pull is shorthand for git fetch followed by git merge FETCH_HEAD" More precisely, git pull runs git fetch with the given parameters and then calls git merge to merge the retrieved branch heads into the current branch"

(Ref: https://git-scm.com/docs/git-pull)

For your second statement/question:

'But what is the difference between git pull VS git fetch + git rebase'

Again, from same source:
git pull --rebase

"With --rebase, it runs git rebase instead of git merge."

Now, if you wanted to ask

'the difference between merge and rebase'

that is answered here too:
https://git-scm.com/book/en/v2/Git-Branching-Rebasing
(the difference between altering the way version history is recorded)

About efficient method. You can use CursorLoader. For example I included my action. And you must implement ContentProvider for your data base. https://developer.android.com/reference/android/content/ContentProvider.html

If you implement this, you will call you data base very efficient.

public class LoadEntitiesActionImp implements LoaderManager.LoaderCallbacks<Cursor> {

   public interface OnLoadEntities {
       void onSuccessLoadEntities(List<Entities> entitiesList);
   }

    private OnLoadEntities onLoadEntities;

    private final Context context;

    private final LoaderManager loaderManager;

    public LoadEntitiesActionImp(Context context, LoaderManager loaderManager) {
        this.context = context;
        this.loaderManager = loaderManager;
    }

    public void setCallback(OnLoadEntities onLoadEntities) {
        this.onLoadEntities = onLoadEntities;
    }

    public void loadEntities() {
        loaderManager.initLoader(LOADER_ID, null, this);
    }

    @Override
    public Loader<Cursor> onCreateLoader(int id, Bundle args) {
        return new CursorLoader(context, YOUR_URI, null, YOUR_SELECTION, YOUR_ARGUMENTS_FOR_SELECTION, YOUR_SORT_ORDER);
    }

    @Override
    public void onLoadFinished(Loader<Cursor> loader, Cursor cursor) {
    }

    @Override
    public void onLoaderReset(Loader<Cursor> loader) {
    }

You may need to check who the actual owner of the stored procedure is. If it is a specific different user then that could be why you can't access it.

Are you sure? This forum thread suggests it might be your watch window. Try outputting the string to a MsgBox, which can display a maximum of 1024 characters:

Semantically what you are trying is invalid html, table element cannot have a div element as a direct child. What you can do is, get your div element inside a td element and than try to hide it

This message digital envelope routines: EVP_DecryptFInal_ex: bad decrypt can also occur when you encrypt and decrypt with an incompatible versions of openssl.

The issue I was having was that I was encrypting on Windows which had version 1.1.0 and then decrypting on a generic Linux system which had 1.0.2g.

It is not a very helpful error message!

Working solution:

A possible solution from @AndrewSavinykh that worked for many (see the comments):

Default digest has changed between those versions from md5 to sha256. One can specify the default digest on the command line as -md sha256 or -md md5 respectively

You are getting confused with transclude: true, which would append the inner content.

replace: true means that the content of the directive template will replace the element that the directive is declared on, in this case the <div myd1> tag.

http://plnkr.co/edit/k9qSx15fhSZRMwgAIMP4?p=preview

For example without replace:true

<div myd1><span class="replaced" myd1="">directive template1</span></div>

and with replace:true

<span class="replaced" myd1="">directive template1</span>

As you can see in the latter example, the div tag is indeed replaced.

Why not run something like Nexus, your own maven repo that you can upload 3rd party proprietary jar files, and also proxy other public repositories, to save on bandwith?

This also has some good reasons to run your own maven repository manager.

Do like this

List<Object[]> list = HQL.list(); // get your lsit here but in Object array

your query is : "SELECT houses.id, addresses.country, addresses.region,..."

for(Object[] obj : list){
String houseId = String.valueOf(obj[0]); // houseId is at first place in your query
String country = String.valueof(obj[1]); // country is at second and so on....
.......
}

this way you can get the mixed objects with ease, but you should know in advance at which place what value you are getting or you can just check by printing the values to know. sorry for the bad english I hope this help

They are the same thing. .hide() calls a jQuery function and allows you to add a callback function to it. So, with .hide() you can add an animation for instance.

.css("display","none") changes the attribute of the element to display:none. It is the same as if you do the following in JavaScript:

document.getElementById('elementId').style.display = 'none';

The .hide() function obviously takes more time to run as it checks for callback functions, speed, etc...

Get the Sothink SWF decompiler. Not free, but worth it. Recently used it to decompile an SWF that I had lost the fla for, and I could completely round-trip swf-fla and back!
