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

This will be a JRE and JDK package.

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

Because the bootstrap-select is a bootstrap component and therefore you need to include it in your code as you did for your V3

NOTE: this component only works in boostrap-4 since version 1.13.0

$('select').selectpicker();

It's not fancy I known but you could use a callback class, create a hostbuilder and set the configuration to a static property.

For asp core 2.2:

using Microsoft.AspNetCore;
using Microsoft.AspNetCore.Builder;
using Microsoft.AspNetCore.Hosting;
using Microsoft.Extensions.Configuration;
using System;

namespace Project
{
    sealed class Program
    {
        #region Variables
        /// <summary>
        /// Last loaded configuration
        /// </summary>
        private static IConfiguration _Configuration;
        #endregion

        #region Properties
        /// <summary>
        /// Default application configuration
        /// </summary>
        internal static IConfiguration Configuration
        {
            get
            {
                // None configuration yet?
                if (Program._Configuration == null)
                {
                    // Create the builder using a callback class
                    IWebHostBuilder builder = WebHost.CreateDefaultBuilder().UseStartup<CallBackConfiguration>();

                    // Build everything but do not initialize it
                    builder.Build();
                }

                // Current configuration
                return Program._Configuration;
            }

            // Update configuration
            set => Program._Configuration = value;
        }
        #endregion

        #region Public
        /// <summary>
        /// Start the webapp
        /// </summary>
        public static void Main(string[] args)
        {
            // Create the builder using the default Startup class
            IWebHostBuilder builder = WebHost.CreateDefaultBuilder(args).UseStartup<Startup>();

            // Build everything and run it
            using (IWebHost host = builder.Build())
                host.Run();
        }
        #endregion


        #region CallBackConfiguration
        /// <summary>
        /// Aux class to callback configuration
        /// </summary>
        private class CallBackConfiguration
        {
            /// <summary>
            /// Callback with configuration
            /// </summary>
            public CallBackConfiguration(IConfiguration configuration)
            {
                // Update the last configuration
                Program.Configuration = configuration;
            }

            /// <summary>
            /// Do nothing, just for compatibility
            /// </summary>
            public void Configure(IApplicationBuilder app, IHostingEnvironment env)
            {
                //
            }
        }
        #endregion
    }
}

So now on you just use the static Program.Configuration at any other class you need it.

I had similar situation. I found that one of my config maps was duplicated. I had two configmaps for the same namespace. One had the correct namespace reference, the other was pointing to the wrong namespace.

I deleted and recreated the configmap with the correct file (or fixed file). I am only using one, and that seemed to make the particular cluster happier.

So I would check the files for any typos or duplicate items that could be causing conflict.

Add this dependency:

<dependency>
    <groupId>org.glassfish.jersey.inject</groupId>
    <artifactId>jersey-hk2</artifactId>
    <version>2.28</version>
</dependency>

cf. https://stackoverflow.com/a/44536542/1070215

Make sure not to mix your Jersey dependency versions. This answer says version "2.28", but use whatever version your other Jersey dependency versions are.

I got the same exception when I locally tested. The problem was a URL schema in my request.

Change https:// to http:// in your client url.

Probably it helps.

Try rerunning the pod and running

 kubectl get pods --watch

to watch the status of the pod as it progresses.

In my case, I would only see the end result, 'CrashLoopBackOff,' but the docker container ran fine locally. So I watched the pods using the above command, and I saw the container briefly progress into an OOMKilled state, which meant to me that it required more memory.

Adding "relaxedQueryChars" attribute to the server.xml worked for me :

<Connector connectionTimeout="20000" port="8080" protocol="HTTP/1.1" redirectPort="443" URIEncoding="UTF-8" relaxedQueryChars="[]|{}^&#x5c;&#x60;&quot;&lt;&gt;"/>

I encountered a similar issue, but putting it in my page’s module didn’t work.

I had created a component, which needed a pipe. This component was declared and exported in a ComponentsModule file, which holds all of the app’s custom components.

I had to put my PipesModule in my ComponentsModule as an import, in order for these components to use these pipes and not in the page’s module using that component.

This is rather verbose and don't like it but it's the only thing that worked for me:

if (inputFile && inputFile.current) {
        ((inputFile.current as never) as HTMLInputElement).click()
}

only

if (inputFile && inputFile.current) {
        inputFile.current.click() // also with ! or ? didn't work
}

didn't work for me. Typesript version: 3.9.7 with eslint and recommended rules.

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

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

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

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

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

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

ExternalCallBadRequestException and ExternalCallServerErrorException are the custom exceptions here.

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

After reviewing MySQL 5.7 changes, MySql stopped supporting zero values in date / datetime.

It's incorrect to use zeros in date or in datetime, just put null instead of zeros.

There was conflict in java version. Resolved after using 1.8 for maven.

Possible solution that worked for me with jest

});

I had the same error message. In my case, Jackson consisted of multiple JAR files. Sadly, they had different versions of jackson-core and jackson-annotations which resulted in the above exception.

Maybe you don't have the jackson-annotation JAR in your classpath, at least not in the correct version. You can analyze the used library versions with the command mvn dependency:tree.

When using React hooks there is no access to access to this.props.location. To capture url parameters use window object.

const search = window.location.search;
const params = new URLSearchParams(search);
const foo = params.get('bar');

also try to increase gradle version in your project's build.gradle. It helped me

I managed to fix it finally. The problem is not related to HikariCP. The problem persisted because of some complex methods in REST controllers executing multiple changes in DB through JPA repositories. For some reasons calls to these interfaces resulted in a growing number of "freezed" active connections, exhausting the pool. Either annotating these methods as @Transactional or enveloping all the logic in a single call to transactional service method seem to solve the problem.

Example Code

public class Person {
    public String firstName { get; set; }
    public String lastName { get; set; }
}

// Instantiate Person
var person = new Person { firstName = "Albert", lastName = "Einstein" };

// We can print fullname of the above person as follows
Console.WriteLine("Full-Name - " + person.firstName + " " + person.lastName);
Console.WriteLine("Full-Name - {0} {1}", person.firstName, person.lastName);
Console.WriteLine($"Full-Name - {person.firstName} {person.lastName}");

Output

Full-Name - Albert Einstein
Full-Name - Albert Einstein
Full-Name - Albert Einstein

It is Interpolated Strings. You can use an interpolated string anywhere you can use a string literal. When running your program would execute the code with the interpolated string literal, the code computes a new string literal by evaluating the interpolation expressions. This computation occurs each time the code with the interpolated string executes.

Following example produces a string value where all the string interpolation values have been computed. It is the final result and has type string. All occurrences of double curly braces (“{{“ and “}}”) are converted to a single curly brace.

string text = "World";
var message = $"Hello, {text}";

After executing above 2 lines, variable message contains "Hello, World".

Console.WriteLine(message); // Prints Hello, World

It might be that you are forgetting to specify the settings which was the case with me.

Try:

mvn clean install -s settings_file.xml

I was struggling with same problem for VSTest framework and my native unit tests.

So, after doing all those things you mentioned before, I removed every occurence of '#' symbol in my solution's directory path. It actually works.

I'm leaving it here for googlers who will find this question in future.

I had the same issue. It would hang immediately, as soon as it said "Applying Microsoft Visual Studio 2015." There was only a small sliver in the progress bar. I even let the install run overnight. There was no disk activity or CPU usage from the installer.

What finally worked was to kill the process in Task Manager and restart the computer. As soon as I rebooted, the installer opened up automatically and completed successfully.

It might be obvious, but make sure that you are sending to the parser URL object not a String containing www adress. This will not work:

    ObjectMapper mapper = new ObjectMapper();
    String www = "www.sample.pl";
    Weather weather = mapper.readValue(www, Weather.class);

But this will:

    ObjectMapper mapper = new ObjectMapper();
    URL www = new URL("http://www.oracle.com/");
    Weather weather = mapper.readValue(www, Weather.class);

I found this extention very usefull: StoredProcedureEFCore

Then the usage is like this

List<Model> rows = null;

ctx.LoadStoredProc("dbo.ListAll")
   .AddParam("limit", 300L)
   .AddParam("limitOut", out IOutParam<long> limitOut)
   .Exec(r => rows = r.ToList<Model>());

long limitOutValue = limitOut.Value;

ctx.LoadStoredProc("dbo.ReturnBoolean")
   .AddParam("boolean_to_return", true)
   .ReturnValue(out IOutParam<bool> retParam)
   .ExecNonQuery();

bool b = retParam.Value;

ctx.LoadStoredProc("dbo.ListAll")
   .AddParam("limit", 1L)
   .ExecScalar(out long l);

Added AWS dependency and had this error. When I remove it from pom the error is gone. Probably you might have the same situation.

It also disturb me a lot but now it is fine The solution is very simple (written blow) [window (android studio)]

1. go to C:\Users\your user name.gradle
2. open wrapper/dists and delete the folder that is distrubing you in my case --gradle-6.5--
3. then go back to .gradle folder and this time open daemon folder and delete the folder with same number that is disturbing you in my case --6.5--
4. Then again go back to .gradle folder and this time open caches folder and delete the folder with same number that is disturbing you in my case --6.5--
5. now if your android studio is open then close it and again start it but this time with administrator mode by right clicking on the icon of android studio icon it is important
6. you should have internet connection and now your android studio will setup every thing by its own (please don't distrub it while it is doing its operation)

Bootstrap 3.3.7:

Use form-inline.

It only works on screen resolutions greater than 768px though. To test the snippet below make sure to click the "Expand snippet" link to get a wider viewing area.

            <input type="text" class="form-control"/>-<input type="text" class="form-control"/>_x000D_
        </form>

Reference: https://getbootstrap.com/docs/3.3/css/#forms-inline

Here are my working example

@RequestMapping(value = "/api/v1/files/upload", method =RequestMethod.POST)
public ResponseEntity<?> upload(@RequestParam("files") MultipartFile[] files) {
    LinkedMultiValueMap<String, Object> map = new LinkedMultiValueMap<>();
    List<String> tempFileNames = new ArrayList<>();
    String tempFileName;
    FileOutputStream fo;

    try {
        for (MultipartFile file : files) {
            tempFileName = "/tmp/" + file.getOriginalFilename();
            tempFileNames.add(tempFileName);
            fo = new FileOutputStream(tempFileName);
            fo.write(file.getBytes());
            fo.close();
            map.add("files", new FileSystemResource(tempFileName));
        }

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

        HttpEntity<LinkedMultiValueMap<String, Object>> requestEntity = new HttpEntity<>(map, headers);
        String response = restTemplate.postForObject(uploadFilesUrl, requestEntity, String.class);

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

    for (String fileName : tempFileNames) {
        File f = new File(fileName);
        f.delete();
    }
    return new ResponseEntity<Object>(HttpStatus.OK);
}

When Bootstrap Select initializes, it'll build a set of custom divs that run alongside the original <select> element and will typically synchronize state between the two input mechanisms.

Which is to say that one way to handle events on bootstrap select is to listen for events on the original select that it modifies, regardless of who updated it.

Solution 1 - Native Events

Just listen for a change event and get the selected value using javascript or jQuery like this:

$('select').on('change', function(e){
  console.log(this.value,
              this.options[this.selectedIndex].value,
              $(this).find("option:selected").val(),);
});

^{*NOTE: As with any script reliant on the DOM, make sure you wait for the DOM ready event before executing}

Demo in Stack Snippets:

$(function() {_x000D_
_x000D_
  $('select').on('change', function(e){_x000D_
    console.log(this.value,_x000D_
                this.options[this.selectedIndex].value,_x000D_
                $(this).find("option:selected").val(),);_x000D_
  });_x000D_
  _x000D_
});

<select class="selectpicker">_x000D_
  <option val="Must"> Mustard </option>_x000D_
  <option val="Cat" > Ketchup </option>_x000D_
  <option val="Rel" > Relish  </option>_x000D_
</select>

Solution 2 - Bootstrap Select Custom Events

As this answer alludes, Bootstrap Select has their own set of custom events, including changed.bs.select which:

fires after the select's value has been changed. It passes through event, clickedIndex, newValue, oldValue.

And you can use that like this:

$("select").on("changed.bs.select", 
      function(e, clickedIndex, newValue, oldValue) {
    console.log(this.value, clickedIndex, newValue, oldValue)
});

Demo in Stack Snippets:

$(function() {_x000D_
_x000D_
  $("select").on("changed.bs.select", _x000D_
        function(e, clickedIndex, newValue, oldValue) {_x000D_
      console.log(this.value, clickedIndex, newValue, oldValue)_x000D_
  });_x000D_
_x000D_
});

<select class="selectpicker">_x000D_
  <option val="Must"> Mustard </option>_x000D_
  <option val="Cat" > Ketchup </option>_x000D_
  <option val="Rel" > Relish  </option>_x000D_
</select>

On CentOS Linux release 7.5.1804, we were able to make this work by editing /etc/selinux/config and changing the setting of SELINUX like so:

SELINUX=disabled

if you are accessing it from different module or Target then you just need it to public it

SELECT2 < V4

Step #1: HTML

<input name="mySelect2" type="hidden" id="mySelect2">

Step #2: Create an instance of Select2

$("#mySelect2").select2({
      placeholder: "My Select 2",
      multiple: false,
      minimumInputLength: 1,
      ajax: {
          url: "/elements/all",
          dataType: 'json',
          quietMillis: 250,
          data: function(term, page) {
              return {
                  q: term,
              };
          },
          results: function(data, page) {
              return {results: data};
          },
          cache: true
      },
      formatResult: function(element){
          return element.text + ' (' + element.id + ')';
      },
      formatSelection: function(element){
          return element.text + ' (' + element.id + ')';
      },
      escapeMarkup: function(m) {
          return m;
      }
});

Step #3: Set your desired value

$("#mySelect2").select2('data', { id:"elementID", text: "Hello!"});

If you use select2 without AJAX you can do as follow:

<select name="mySelect2" id="mySelect2">
  <option value="0">One</option>
  <option value="1">Two</option>
  <option value="2">Three</option>
</select>

/* "One" will be the selected option */
$('[name=mySelect2]').val("0");

You can also do so:

$("#mySelect2").select2("val", "0");

SELECT2 V4

For select2 v4 you can append directly an option/s as follow:

<select id="myMultipleSelect2" multiple="" name="myMultipleSelect2[]">
    <option value="TheID" selected="selected">The text</option>                                                                   
</select>

Or with JQuery:

var $newOption = $("<option selected='selected'></option>").val("TheID").text("The text")
 
$("#myMultipleSelect2").append($newOption).trigger('change');

other example

$("#myMultipleSelect2").val(5).trigger('change');

It is not possible with the static methods of Collectors. The javadoc of toMap explains that toMap is based on Map.merge:

@param mergeFunction a merge function, used to resolve collisions between values associated with the same key, as supplied to Map#merge(Object, Object, BiFunction)}

and the javadoc of Map.merge says:

@throws NullPointerException if the specified key is null and this map does not support null keys or the value or remappingFunction is null

You can avoid the for loop by using the forEach method of your list.

Map<Integer,  Boolean> answerMap = new HashMap<>();
answerList.forEach((answer) -> answerMap.put(answer.getId(), answer.getAnswer()));

but it is not really simple than the old way:

Map<Integer, Boolean> answerMap = new HashMap<>();
for (Answer answer : answerList) {
    answerMap.put(answer.getId(), answer.getAnswer());
}

If you need security as a dependency but don't want Spring Boot to configure it for you, you can use this exclusion:

    @EnableAutoConfiguration(exclude = { 
        org.springframework.boot.autoconfigure.security.SecurityAutoConfiguration.class 
    })

playSound is a static method meaning it exists when the program is loaded. audioSounds and minTime are SoundManager instance variable, meaning they will exist within an instance of SoundManager. You have not created an instance of SoundManager so audioSounds doesn't exist (or it does but you do not have a reference to a SoundManager object to see that).

To solve your problem you can either make audioSounds static:

public static List<AudioSource> audioSounds = new List<AudioSource>();
public static double minTime = 0.5;

so they will be created and may be referenced in the same way that PlaySound will be. Alternatively you can create an instance of SoundManager from within your method:

SoundManager soundManager = new SoundManager();
foreach (AudioSource sound in soundManager.audioSounds) // Loop through List with foreach
{
    if (sourceSound.name != sound.name && sound.time <= soundManager.minTime)
    {
        playsound = true;
    }
}

With Spring Boot + Spring Data it has become quite easy:

@RunWith(SpringRunner.class)
@DataJpaTest
public class MyRepositoryTest {

    @Autowired
    MyRepository subject;

    @Test
    public void myTest() throws Exception {
        subject.save(new MyEntity());
    }
}

The solution by @heez brings up the full context, this only bring up what is needed for JPA+Transaction to work. Note that the solution above will bring up a in memory test database given that one can be found on the classpath.

I found the error: I have a library that it was built using jdk 1.6. The Spring main controller and components are in this library. And how I use jdk 1.7, It does not find the classes built in 1.6.

The solution was built all using "compiler compliance level: 1.7" and "Generated .class files compatibility: 1.6", "Source compatibility: 1.6".

I setup this option in Eclipse: Preferences\Java\Compiler.

Thanks everybody.

Your Custom AuthenticationProvider class should be annotated with the following:

@Transactional

This will make sure the presence of the hibernate session there as well.

Found the solution in Spring security examples posted in Github.

WebSecurityConfigurerAdapter has a overloaded configure message that takes WebSecurity as argument which accepts ant matchers on requests to be ignored.

@Override
public void configure(WebSecurity web) throws Exception {
    web.ignoring().antMatchers("/authFailure");
}

See Spring Security Samples for more details

Please remove . from your target it should be a id

<a href="#bannerformmodal" data-toggle="modal" data-target="#bannerformmodal">Load me</a>

Also you have to give your modal id like below

<div class="modal fade bannerformmodal" tabindex="-1" role="dialog" aria-labelledby="bannerformmodal" aria-hidden="true" id="bannerformmodal">

Here is the solution in a fiddle.

you put resource-ref in the description tag in web.xml

The solution at my end was to explicitly add a JoinColumn annotation like this:

@JoinColumn(name="mapping_type_id")

The column name is usually the table name + "_id" if there is an id field. Additionally, keep in mind which field it should be based on the relationship, OneToMany or ManyToOne.

Hope this helps.

A tip for others: if you have NI applications installed, the NI Application Web Server also uses the port 8080.

In my case (Spring MVC + Hibernate project), I added Controller, Service, Dao, Model class & Thyme leaf page. Just didn't map new model class in "hibernate.cfg.xml" file. So that got this error. But after mapping new model class again got the error. Then deleted Controller, Service, Dao, Model class. Thyme leaf page and Created newly. Also mapped new model class. Then error has gone.

To make little more easy to understand use like below, which i prefer the most. Also it permits to call multiple function at once. Obviously

setTimeout(function(){
      startTimer();
      function2();
      function3();
}, startInterval);

As mentioned above the following would solve the problem: mapper.configure(DeserializationFeature.ACCEPT_SINGLE_VALUE_AS_ARRAY, true);

However in my case the provider did this [0..1] or [0..*] serialization rather as a bug and I could not enforce fixing. On the other hand it did not want to impact my strict mapper for all other cases which needs to be validated strictly.

So I did a Jackson NASTY HACK (which should not be copied in general ;-) ), especially because my SingleOrListElement had only few properties to patch:

@JsonProperty(value = "SingleOrListElement", access = JsonProperty.Access.WRITE_ONLY)
private Object singleOrListElement; 

public List<SingleOrListElement> patch(Object singleOrListElement) {
  if (singleOrListElement instanceof List) {
    return (ArrayList<SingleOrListElement>) singleOrListElement;
  } else {
    LinkedHashMap map = (LinkedHashMap) singleOrListElement;
    return Collections.singletonList(SingletonList.builder()
                            .property1((String) map.get("p1"))
                            .property2((Integer) map.get("p2"))
                            .build());
  }

I was getting same issue, i.e. protocol handler start failed. Cause was port is already in use. I found whether the port was in use or not. It was. So I killed the process that was running on that port and restarted my spring boot application. And it worked. :)

Your problem is this

<button type="button" value=" Send" class="btn btn-success" type="submit" id="submit" />

You've set the type twice. Your browser is only accepting the first, which is "button".

<button type="submit" value=" Send" class="btn btn-success" id="submit" />

I got same error in my Micro-service, whenever you declare @Value annotation in program i.e @Value("${project.api.key}")

make sure that your application.properties file with same values should not be blank project.api.key= add some values

MostIMP :otherwise it will throw error "Error creating bean with name 'ServiceFTP': Injection of autowired dependencies"

I think you should not rely on the implicit conversion. It is a bad practice.

Instead you should try like this:

datenum >= to_date('11/26/2013','mm/dd/yyyy')

or like

datenum >= date '2013-09-01'

This exception come due to you are providing listener ContextLoaderListener

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

but you are not providing context-param for your spring configuration file. like applicationContext.xml You must provide below snippet for your configuration

<context-param>
    <param-name>contextConfigLocation</param-name>
    <param-value>applicationContext.xml</param-value>
</context-param>

If You are providing the java based spring configuration , means you are not using xml file for spring configuration at that time you must provide below code:

<!-- Configure ContextLoaderListener to use AnnotationConfigWebApplicationContext
instead of the default XmlWebApplicationContext -->
<context-param>
    <param-name>contextClass</param-name>
    <param-value>
    org.springframework.web.context.support.AnnotationConfigWebApplicationContext
    </param-value>
</context-param>

<!-- Configuration locations must consist of one or more comma- or space-delimited
fully-qualified @Configuration classes. Fully-qualified packages may also
be specified for component-scanning -->
<context-param>
    <param-name>contextConfigLocation</param-name>
    <param-value>com.nirav.modi.config.SpringAppConfig</param-value>
</context-param>

it looks like your custom JpaRepository method name does not match any Variable in your entity classs. Make sure your method name matches a variable in your entity class

for example: you got a variable name called "active" and your custom JpaRepository method says "findByActiveStatus" and since there is no variable called "activeStatus" it will throw"PropertyReferenceException"

This is the normal behavior and the reason is that your sqlCommandHandlerService.persist method needs a TX when being executed (because it is marked with @Transactional annotation). But when it is called inside processNextRegistrationMessage, because there is a TX available, the container doesn't create a new one and uses existing TX. So if any exception occurs in sqlCommandHandlerService.persist method, it causes TX to be set to rollBackOnly (even if you catch the exception in the caller and ignore it).

To overcome this you can use propagation levels for transactions. Have a look at this to find out which propagation best suits your requirements.

Update; Read this!

Well after a colleague came to me with a couple of questions about a similar situation, I feel this needs a bit of clarification.
Although propagations solve such issues, you should be VERY careful about using them and do not use them unless you ABSOLUTELY understand what they mean and how they work. You may end up persisting some data and rolling back some others where you don't expect them to work that way and things can go horribly wrong.

There is always a reason why the nested method roll back. If you don't see the reason, you need to change your logger level to debug, where you will see the more details where transaction failed. I changed my logback.xml by adding

<logger name="org.springframework.transaction" level="debug"/>
<logger name="org.springframework.orm.jpa" level="debug"/>

then I got this line in the log:

Participating transaction failed - marking existing transaction as rollback-only

So I just stepped through my code to see where this line is generated and found that there is a catch block which did not throw anything.

private Student add(Student s) {
        try {
            Student retval = studentRepository.save(s);
            return retval;
        } catch (Exception e) {
            
        }
        return null;
    }

If both columns can contain NULL, but you still want to merge them to a single string, the easiest solution is to use CONCAT_WS():

SELECT FirstName AS First_Name
     , LastName AS Last_Name
     , CONCAT_WS('', ContactPhoneAreaCode1, ContactPhoneNumber1) AS Contact_Phone 
  FROM TABLE1

This way you won't have to check for NULL-ness of each column separately.

Alternatively, if both columns are actually defined as NOT NULL, CONCAT() will be quite enough:

SELECT FirstName AS First_Name
     , LastName AS Last_Name
     , CONCAT(ContactPhoneAreaCode1, ContactPhoneNumber1) AS Contact_Phone 
  FROM TABLE1

As for COALESCE, it's a bit different beast: given the list of arguments, it returns the first that's not NULL.

Regarding the original question asked in the title ...

• sudo apt-get install libtcnative-1

• or if you are on RHEL Linux yum install tomcat-native

The documentation states you need http://tomcat.apache.org/native-doc/

• sudo apt-get install libapr1.0-dev libssl-dev
• or RHEL yum install apr-devel openssl-devel

use table

<table align="center" width="100%" cellpadding="0" cellspacing="0" border="0">

Go to project properties -> configurations properties -> C/C++ -> treats warning as error -> No (/WX-).

First check your listener is on or off. Go to net manager then Local -> service naming -> orcl. Then change your HOST NAME and put your PC name. Now go to LISTENER and change the HOST and put your PC name.

Check that if you have a static handler in your class. If so, please be careful, cause static handler only could be initiated in thread which has a looper, the crash could be triggered in this way:

1.firstly, create the instance of class in a simple thread and catch the crash.

2.then call the field method of Class in main thread, you will get the NoClassDefFoundError.

here is the test code:

public class MyClass{
       private static  Handler mHandler = new Handler();
       public static int num = 0;
}

in your onCrete method of Main activity, add test code part:

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);
    //test code start
    new Thread(new Runnable() {
        @Override
        public void run() {
            try {
                MyClass myClass = new MyClass();
            } catch (Throwable e) {
                e.printStackTrace();
            }
        }
    }).start();

    try {
        Thread.sleep(1000);
    } catch (InterruptedException e) {
        e.printStackTrace();
    }
    MyClass.num = 3;
    // end of test code
}

there is a simple way to fix it using a handlerThread to init handler:

private static Handler mHandler;
private static HandlerThread handlerThread = new HandlerThread("newthread");
static {
    handlerThread.start();
    mHandler = new Handler(handlerThread.getLooper(), mHandlerCB);
}

@JulienD Best way is to break above process into two steps.

Step 1 : Lets say 'rawList' as your list that you want to add as parameters in prepared statement.

Create another list :

ArrayList<String> listWithQuotes = new ArrayList<String>();

for(String element : rawList){
    listWithQuotes.add("'"+element+"'");
}

Step 2 : Make 'listWithQuotes' comma separated.

String finalString = StringUtils.join(listWithQuotes.iterator(),",");

'finalString' will be string parameters with each element as single quoted and comma separated.

In General:

An example of an easy way to post XML data and get the response (as a string) would be the following function:

public string postXMLData(string destinationUrl, string requestXml)
{
    HttpWebRequest request = (HttpWebRequest)WebRequest.Create(destinationUrl);
    byte[] bytes;
    bytes = System.Text.Encoding.ASCII.GetBytes(requestXml);
    request.ContentType = "text/xml; encoding='utf-8'";
    request.ContentLength = bytes.Length;
    request.Method = "POST";
    Stream requestStream = request.GetRequestStream();
    requestStream.Write(bytes, 0, bytes.Length);
    requestStream.Close();
    HttpWebResponse response;
    response = (HttpWebResponse)request.GetResponse();
    if (response.StatusCode == HttpStatusCode.OK)
    {
        Stream responseStream = response.GetResponseStream();
        string responseStr = new StreamReader(responseStream).ReadToEnd();
        return responseStr;
    }
    return null;
}

In your specific situation:

Instead of:

request.ContentType = "application/x-www-form-urlencoded";

use:

request.ContentType = "text/xml; encoding='utf-8'";

Also, remove:

string postData = "XMLData=" + Sendingxml;

And replace:

byte[] byteArray = Encoding.UTF8.GetBytes(postData);

with:

byte[] byteArray = Encoding.UTF8.GetBytes(Sendingxml.ToString());

Use above annotation if someone is facing :--org.hibernate.jpa.HibernatePersistenceProvider persistence provider when it attempted to create the container entity manager factory for the paymentenginePU persistence unit. The following error occurred: [PersistenceUnit: paymentenginePU] Unable to build Hibernate SessionFactory ** This is a solution if you are using Audit table.@Audit

Use:- @Audited(targetAuditMode = RelationTargetAuditMode.NOT_AUDITED) on superclass.

All you have to do is In your bLoanButton_Click , add a line to rebind the Grid to the SqlDataSource :

protected void bLoanButton_Click(object sender, EventArgs e)
{

//your same code
........

GridView1.DataBind();


}

regards

I deleted my project (root folder) and created it again. It was the fastest and simplest way in my case.

Do not forget to save all you changes, before you delete you project!

just compiled your code and the only thing that is missing from it is that you have to Bind your ddl2 to an empty datasource before binding it again like this:

Protected Sub ddl1_SelectedIndexChanged(ByVal sender As Object, ByVal e As EventArgs) //ddl2.Items.Clear()

ddl2.DataSource=New List(Of String)()
ddl2.DataSource = sql2
ddl2.DataBind() End Sub

and it worked just fine

The communication link between the driver and the data source to which the driver was attempting to connect failed before the function completed processing. So usually its a network error. This could be caused by packet drops or badly configured Firewall/Switch.

INFO: No Spring WebApplicationInitializer types detected on classpath.

Can also show up if you're using Maven with Eclipse and deploying your WAR using;

(Eclipse, Kepler, with M2)

(right-click on your project) -> Run As -> Run on Server

It's down to the generation and deletion of the m2e-wtp folder and contents.

Make sure, Maven Archive generated files under the build directory is checked.

Under: "Window -> preferences -> Maven -> Java EE Integration"

Then:

Use M2, to do your build, i.e. the usual Clean -> package or Install etc...

If "Project -> Build Automatically" is not selected. You can force the "m2e-wtp folder and contents" generation by doing;

"(right-click on your project) -> Maven -> Update Project..."

Note: make sure the "Clean Projects" option is un-selected. Otherwise the contents of target/classes will be deleted and you're back to square one.

Also,when;

"Project -> Build Automatically" is selected the "m2e-wtp folder and contents" is generated

or "Project -> Build All"

or "(right-click on project) -> Build Project"

In reply to Dimitrys answer but using Ajax.BeginForm the following works at least with MVC >5 (4 not tested).

1. write a model as shown in the other answers,

2. In the "parent view" you will probably use a table to show the data. Model should be an ienumerable. I assume, the model has an id-property. Howeverm below the template, a placeholder for the modal and corresponding javascript

   <table>
   @foreach (var item in Model)
   {
       <tr> <td id="[email protected]"> 
           @Html.Partial("dataRowView", item)
       </td> </tr>
   }
   </table>
   
   <div class="modal fade" id="editor-container" tabindex="-1" 
        role="dialog" aria-labelledby="editor-title">
       <div class="modal-dialog modal-lg" role="document">
           <div class="modal-content" id="editor-content-container"></div>
       </div>
   </div> 
   
   <script type="text/javascript">
       $(function () {
           $('.editor-container').click(function () {
               var url = "/area/controller/MyEditAction";  
               var id = $(this).attr('data-id');  
               $.get(url + '/' + id, function (data) {
                   $('#editor-content-container').html(data);
                   $('#editor-container').modal('show');
               });
           });
       });
   
       function success(data,status,xhr) {
           $('#editor-container').modal('hide');
           $('#editor-content-container').html("");
       }
   
       function failure(xhr,status,error) {
           $('#editor-content-container').html(xhr.responseText);
           $('#editor-container').modal('show');
       }
   </script>
   

note the "editor-success-id" in data table rows.

3. The dataRowView is a partial containing the presentation of an model's item.

   @model ModelView
   @{
       var item = Model;
   }
   <div class="row">
           // some data 
           <button type="button" class="btn btn-danger editor-container" data-id="@item.Id">Edit</button>
   </div>
   

4. Write the partial view that is called by clicking on row's button (via JS $('.editor-container').click(function () ... ).

   @model Model
   <div class="modal-header">
       <button type="button" class="close" data-dismiss="modal" aria-label="Close">
           <span aria-hidden="true">&times;</span>
       </button>
       <h4 class="modal-title" id="editor-title">Title</h4>
   </div>
   @using (Ajax.BeginForm("MyEditAction", "Controller", FormMethod.Post,
                       new AjaxOptions
                       {
                           InsertionMode = InsertionMode.Replace,
                           HttpMethod = "POST",
                           UpdateTargetId = "editor-success-" + @Model.Id,
                           OnSuccess = "success",
                           OnFailure = "failure",
                       }))
   {
       @Html.ValidationSummary()
       @Html.AntiForgeryToken()
       @Html.HiddenFor(model => model.Id)
       <div class="modal-body">
           <div class="form-horizontal">
               // Models input fields
           </div>
       </div>
       <div class="modal-footer">
           <button type="button" class="btn btn-default" data-dismiss="modal">Cancel</button>
           <button type="submit" class="btn btn-primary">Save</button>
       </div>
   }
   

This is where magic happens: in AjaxOptions, UpdateTargetId will replace the data row after editing, onfailure and onsuccess will control the modal.

This is, the modal will only close when editing was successful and there have been no errors, otherwise the modal will be displayed after the ajax-posting to display error messages, e.g. the validation summary.

But how to get ajaxform to know if there is an error? This is the controller part, just change response.statuscode as below in step 5:

5. the corresponding controller action method for the partial edit modal

   [HttpGet]
   public async Task<ActionResult> EditPartData(Guid? id)
   {
       // Find the data row and return the edit form
       Model input = await db.Models.FindAsync(id);
       return PartialView("EditModel", input);
   }
   
   [HttpPost, ValidateAntiForgeryToken]
   public async Task<ActionResult> MyEditAction([Bind(Include =
      "Id,Fields,...")] ModelView input)
   {
       if (TryValidateModel(input))
       {  
           // save changes, return new data row  
           // status code is something in 200-range
           db.Entry(input).State = EntityState.Modified;
           await db.SaveChangesAsync();
           return PartialView("dataRowView", (ModelView)input);
       }
   
       // set the "error status code" that will redisplay the modal
       Response.StatusCode = 400;
       // and return the edit form, that will be displayed as a 
       // modal again - including the modelstate errors!
       return PartialView("EditModel", (Model)input);
   }
   

This way, if an error occurs while editing Model data in a modal window, the error will be displayed in the modal with validationsummary methods of MVC; but if changes were committed successfully, the modified data table will be displayed and the modal window disappears.

Note: you get ajaxoptions working, you need to tell your bundles configuration to bind jquery.unobtrusive-ajax.js (may be installed by NuGet):

        bundles.Add(new ScriptBundle("~/bundles/jqueryajax").Include(
                    "~/Scripts/jquery.unobtrusive-ajax.js"));

Leaving my specific solution of this for prosperity, as it's a tricky version of this problem:

Type 'System.Linq.Enumerable+WhereSelectArrayIterator[T...] was not marked as serializable

Due to a class with an attribute IEnumerable<int> eg:

[Serializable]
class MySessionData{
    public int ID;
    public IEnumerable<int> RelatedIDs; //This can be an issue
}

Originally the problem instance of MySessionData was set from a non-serializable list:

MySessionData instance = new MySessionData(){ 
    ID = 123,
    RelatedIDs = nonSerizableList.Select<int>(item => item.ID)
};

The cause here is the concrete class that the Select<int>(...) returns, has type data that's not serializable, and you need to copy the id's to a fresh List<int> to resolve it.

RelatedIDs = nonSerizableList.Select<int>(item => item.ID).ToList();

If you're running in a Linux environment, open the file /etc/hosts.allow add the following line

ALL

Wildcards

Also check the /etc/hostname and /etc/host to see if there might be something wrong there.

I had to change my / etc / host from

127.0.0.1 localhost
127.0.1.1 AMK

to

127.0.0.1 localhost
127.0.0.1 AMK

also wrote in ALL in the file /etc/hosts.allow which was previously completely empty

Now everything works

do not know how safe it is. you have to read more about possible options for /etc/hosts.allow to do something that requires a touch of security.

My way of achieving this is by creating ZipInputStream wrapping class that would handle that would provide only the stream of current entry:

The wrapper class:

public class ZippedFileInputStream extends InputStream {

    private ZipInputStream is;

    public ZippedFileInputStream(ZipInputStream is){
        this.is = is;
    }

    @Override
    public int read() throws IOException {
        return is.read();
    }

    @Override
    public void close() throws IOException {
        is.closeEntry();
    }

}

The use of it:

    ZipInputStream zipInputStream = new ZipInputStream(new FileInputStream("SomeFile.zip"));

    while((entry = zipInputStream.getNextEntry())!= null) {

     ZippedFileInputStream archivedFileInputStream = new ZippedFileInputStream(zipInputStream);

     //... perform whatever logic you want here with ZippedFileInputStream 

     // note that this will only close the current entry stream and not the ZipInputStream
     archivedFileInputStream.close();

    }
    zipInputStream.close();

One advantage of this approach: InputStreams are passed as an arguments to methods that process them and those methods have a tendency to immediately close the input stream after they are done with it.

In Eclipse,

When you use JDBC in your servlet, the driver jar must be placed in the WEB-INF/lib directory of your project.

You must set proxy server for gradle at some time, you can try to change the proxy server ip address in gradle.properties which is under .gradle document

For me, the problem was a ContextRefreshedEvent handler. I was doing some data initilization but at that point in the application the Authentication had not been set. It was a catch 22 since the system needed an authentication to authorize and it needed authorization to get the authentication details :). I ended up loosening the authorization from a class level to a method level.

public static final String URL = "jdbc:sqlserver://localhost:1433;databaseName=dbName";
public static final String USERNAME = "xxxx";
public static final String PASSWORD = "xxxx";

/**
 *  This method
    @param args     command line argument
*/
public static void main(String[] args)
{
   try
   {
        Connection connection;
        DriverManager.registerDriver(new com.microsoft.sqlserver.jdbc.SQLServerDriver());   
        connection = DriverManager.getConnection(MainDriver.URL,MainDriver.USERNAME,
                        MainDriver.PASSWORD);
        String query ="select * from employee";
        Statement statement = connection.createStatement();
        ResultSet resultSet = statement.executeQuery(query);
        while(resultSet.next())
        {
            System.out.print("First Name: " + resultSet.getString("first_name"));
            System.out.println("  Last Name: " + resultSet.getString("last_name"));                
        }
   }catch(Exception ex)
   {
        ex.printStackTrace();
   }
}

you can use an external package if you cant upgrade to 4.5. One such is Ionic.Zip.dll from DotNetZipLib.

For me the best method of retrieving admin pass is by executing cat command inside the running container.

docker exec YOUR_JENKINS_CONTAINER cat /var/jenkins_home/secrets/initialAdminPassword

Just a quick comment: sometimes Maven does not copy the jstl-.jar to the WEB-INF folder even if the pom.xml has the entry for it.

I had to manually copy the JSTL jar to /WEB-INF/lib on the file system. That resolved the problem. The issue may be related to Maven war packaging plugin.

$('.selectpicker option:selected').val();

Just put option:selected to get value, because the bootstrap selectpicker change to and appear in diferent way. But select still there selected

Here's the solution,

If you are a constant proxy changer like me for various reasons (university, home , workplace and so on..) you are mostly likely to get this error due to improper configuration of connection settings in the eclipse IDE. all you have to do it play around with the current settings and get it to working state. Here's how,,

1. GO TO

Window-> Preferences -> General -> Network Connection.

2. Change the Settings

Active Provider-> Manual-> and check---> HTTP, HTTPS and SOCKS

If your active provider is already set to Manual, try restoring the default (native)

That's all, restart Eclipse and you are good to go!

Search the file my.cnf and comment the line

skip-networking

to

#skip-networking

Restart mysql

When you test with device you want to add your PC ip address.

in pc run in cmd Ipconfig

in ubuntu run terminal ifconfig

Then use "http://your_pc_ip_address:8080/register" insted of using "http://10.0.2.2:8080/register"

in my pc = 192.168.1.3

and also add internet permission to Manifest

<uses-permission android:name="android.permission.INTERNET"></uses-permission>

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

if this doesn't work go to your local repos

and search for .lastUpdated and delete them
then build the maven

If you use Kotlin, it supports these nullability annotations in its compiler and will prevent you from passing a null to a java method that requires a non-null argument. Event though this question was originally targeted at Java, I mention this Kotlin feature because it is specifically targeted at these Java annotation and the question was "Is there a way to make these annotations more strictly enforced and/or propagate further?" and this feature does make these annotation more strictly enforced.

Java class using @NotNull annotation

public class MyJavaClazz {
    public void foo(@NotNull String myString) {
        // will result in an NPE if myString is null
        myString.hashCode();
    }
}

Kotlin class calling Java class and passing null for the argument annotated with @NotNull

class MyKotlinClazz {
    fun foo() {
        MyJavaClazz().foo(null)
    }
}  

Kotlin compiler error enforcing the @NotNull annotation.

Error:(5, 27) Kotlin: Null can not be a value of a non-null type String

see: http://kotlinlang.org/docs/reference/java-interop.html#nullability-annotations

In my case, the reason was a simple typo.

If you have a foreign key definition in some table and the name of the foreign key is used elsewhere as another foreign key you will have this error.

I was getting this while running in Java EE Eclipse. None of the answers here helped. What finally did it for me was:

1. maven clean
2. start tomcat in debug

I kept doing a maven clean install and error wouldn't go away. Weird.

This took me way too long to track down. Make sure you minisafe your controller within your directive.

.directive('my_directive', ['injected_item', function (injected_item){

  return {

    controller: ['DO_IT_HERE_TOO', function(DO_IT_HERE_TOO){

    }]
  }
}

Hope that helps

I encountered with same error and resolved it with redeployment after removing deployment.

"No suitable driver" usually means that the JDBC URL you've supplied to connect has incorrect syntax or when the driver isn't loaded at all.

When the method getConnection is called, the DriverManager will attempt to locate a suitable driver from amongst those loaded at initialization and those loaded explicitly using the same classloader as the current applet or application.(using Class.forName())

For Example

import oracle.jdbc.driver.OracleDriver;

Class.forName("oracle.jdbc.driver.­OracleDriver");

Also check that you have ojdbc6.jar in your classpath. I would suggest to place .jar at physical location to JBoss "$JBOSS_HOME/server/default/lib/" directory of your project.

EDIT:

You have mentioned hibernate lately.

Check that your hibernate.cfg.xml file has connection properties something like this:

<property name="hibernate.connection.driver_class">oracle.jdbc.driver.OracleDriver</property>
<property name="hibernate.connection.url">jdbc:oracle:thin:@localhost:1521:orcl</property> 
<property name="hibernate.connection.username">scott</property>
<property name="hibernate.connection.password">tiger</property>

The filter design method in accepted answer is correct, but it has a flaw. SciPy bandpass filters designed with b, a are unstable and may result in erroneous filters at higher filter orders.

Instead, use sos (second-order sections) output of filter design.

from scipy.signal import butter, sosfilt, sosfreqz

def butter_bandpass(lowcut, highcut, fs, order=5):
        nyq = 0.5 * fs
        low = lowcut / nyq
        high = highcut / nyq
        sos = butter(order, [low, high], analog=False, btype='band', output='sos')
        return sos

def butter_bandpass_filter(data, lowcut, highcut, fs, order=5):
        sos = butter_bandpass(lowcut, highcut, fs, order=order)
        y = sosfilt(sos, data)
        return y

Also, you can plot frequency response by changing

b, a = butter_bandpass(lowcut, highcut, fs, order=order)
w, h = freqz(b, a, worN=2000)

to

sos = butter_bandpass(lowcut, highcut, fs, order=order)
w, h = sosfreqz(sos, worN=2000)

I had this problem because I was calling a method

await myClass.myStaticMethod(myString);

but I was setting myString with

var myString = String.Format({some dynamic-type values})

which resulted in a dynamic type, not a string, thus when I tried to await on myClass.myStaticMethod(myString), the compiler thought I meant to call myClass.myStaticMethod(dynamic myString). This compiled fine because, again, in a dynamic context, it's all good until it blows up at run-time, which is what happened because there is no implementation of the dynamic version of myStaticMethod, and this error message didn't help whatsoever, and the fact that Intellisense would take me to the correct definition didn't help either.
Tricky!

However, by forcing the result type to string, like:

var myString = String.Format({some dynamic-type values})

to

string myString = String.Format({some dynamic-type values})

my call to myStaticMethod routed properly

Just use a subquery with INNER JOIN, LEFT JOIN or smth else:

DELETE FROM m_productprice
WHERE m_product_id IN
(
  SELECT B.m_product_id
  FROM   m_productprice  B
    INNER JOIN m_product C 
    ON   B.m_product_id = C.m_product_id
  WHERE  C.upc = '7094' 
  AND    B.m_pricelist_version_id = '1000020'
)

to optimize the query,

• use NOT EXISTS instead of IN
• and WITH for large subqueries

Because i need FetchType to be EAGER, i remove all associations by setting them to (null) and save the object (that remove all association in the database) then delete it!

That add some milliseconds but it's fine for me, if there better way to keep those MS add your comment bellow..

Hope that help someone :)

This is the complete way to omit unneeded redirects, too ;)

These rules are intended to be used in .htaccess files, as a RewriteRule in a *:80 VirtualHost entry needs no Conditions.

RewriteEngine on
RewriteCond %{HTTPS} off [OR] 
RewriteCond %{HTTP:X-Forwarded-Proto} !https
RewriteRule ^/(.*) https://%{HTTP_HOST}/$1 [NC,R=301,L]

Eplanations:

RewriteEngine on

==> enable the engine at all

RewriteCond %{HTTPS} off [OR]

==> match on non-https connections, or (not setting [OR] would cause an implicit AND !)

RewriteCond %{HTTP:X-Forwarded-Proto} !https

==> match on forwarded connections (proxy, loadbalancer, etc.) without https

RewriteRule ^/(.*) https://%{HTTP_HOST}/$1 [NC,R=301,L]

==> if one of both Conditions match, do the rewrite of the whole URL, sending a 301 to have this 'learned' by the client (some do, some don't) and the L for the last rule.

If you're using an embedded driver, the connectString is just

jdbc:derby:databaseName 

(whith options like;create=true;user=xxx etc).

If you're using client driver, the connect string can be left as is, but if changing the driver gives no result... excuse the question, but are you 100% sure you have started the Derby Network Server as per the Derby Tutorial?

I've recently ren into this issue with Commodo cert I bought on ssls.com and I've had 3 files:

domain-name.ca-bundle domain-name.crt and domain-name.p7b

I've had to set it up on Nginx and this is the command I ran:

cat domain-name.ca-bundle domain-name.crt > commodo-ssl-bundle.crt

I then used commodo-ssl-bundle.crt inside the Nginx config file and works like a charm.

So the issue I ran into was this... the application I used to grant the permissions converted the Schema.TableName into a single DB statement in the wrong table, so the grant was indeed wrong, but looked correct when we did a SHOW GRANTS FOR UserName if you weren't paying very close attention to GRANT SELECT vs GRANT TABLE SELECT. Manually correcting the Grant Select on Table w/ proper escaping of Schema.Table solved my issue.

May be unrelated, but I can imagine if one client does this wrong, another might too.

Hope that's helpful.

You can use the NotMapped attribute data annotation to instruct Code-First to exclude a particular property

public class Customer
{
    public int CustomerID { set; get; }
    public string FirstName { set; get; } 
    public string LastName{ set; get; } 
    [NotMapped]
    public int Age { set; get; }
}

[NotMapped] attribute is included in the System.ComponentModel.DataAnnotations namespace.

You can alternatively do this with Fluent API overriding OnModelCreating function in your DBContext class:

protected override void OnModelCreating(DbModelBuilder modelBuilder)
{
   modelBuilder.Entity<Customer>().Ignore(t => t.LastName);
   base.OnModelCreating(modelBuilder);
}

http://msdn.microsoft.com/en-us/library/hh295847(v=vs.103).aspx

The version I checked is EF 4.3, which is the latest stable version available when you use NuGet.

Edit : SEP 2017

Asp.NET Core(2.0)

Data annotation

If you are using asp.net core (2.0 at the time of this writing), The [NotMapped] attribute can be used on the property level.

public class Customer
{
    public int Id { set; get; }
    public string FirstName { set; get; } 
    public string LastName { set; get; } 
    [NotMapped]
    public int FullName { set; get; }
}

Fluent API

public class SchoolContext : DbContext
{
    public SchoolContext(DbContextOptions<SchoolContext> options) : base(options)
    {
    }
    protected override void OnModelCreating(ModelBuilder modelBuilder)
    {
        modelBuilder.Entity<Customer>().Ignore(t => t.FullName);
        base.OnModelCreating(modelBuilder);
    }
    public DbSet<Customer> Customers { get; set; }
}

"there is no problem with tomcat".

I have suffered 4-5 days to resolve the issue (same issue mentioned above). here i was using tomcat 8.5. Finally, the issue got resolved, the issue was with the "Corrupted jar files". You have to delete all your .m2 repository (for me C:\Users\Bandham.m2\repository). den run "mvn clean install" command from your project folder.

happy coding.

Give one UP if it is solved your problem.

I think it comes from this line in your XML file:

<context:component-scan base-package="org.assessme.com.controller." />

Replace it by:

<context:component-scan base-package="org.assessme.com." />

It is because your Autowired service is not scanned by Spring since it is not in the right package.

ISNULL(NULLIF(ColumnName, ' '), NULL) IS NOT NULL

ISNULL(NULLIF(ColumnName, ' '), NULL) IS NULL

Just in case anybody else lands here from Google, I was bitten by this error message when using XDocument.Load(Stream) method.

XDocument xDoc = XDocument.Load(xmlStream);  

Make sure the stream position is set to 0 (zero) before you try and load the Stream, its an easy mistake I always overlook!

if (xmlStream.Position > 0)
{
    xmlStream.Position = 0;
}
XDocument xDoc = XDocument.Load(xmlStream); 

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

it has been a while but my answer may help someone:

if you already defined the relation properly you can use this:

        var res = query.Products.Select(m => new
        {
            productID = product.Id,
            categoryID = m.ProductCategory.Select(s => s.Category.ID).ToList(),
        }).ToList();

Expired certificate was the cause of our "javax.net.ssl.SSLPeerUnverifiedException: peer not authenticated".

I replaced the "localhost" with IP Address (Database server's public IP Address) in the jdbc Url then it worked.

jdbcUrl = "jdbc:oracle:thin:<user>@//localhost:1521/<Service Name>";

??

jdbcUrl = "jdbc:oracle:thin:<user>@//<Public IP Address>:1521/<Service Name>";

I met the same problem as you.

I push two tables result into t1 object and group t1.

 from p in Products                         
  join bp in BaseProducts on p.BaseProductId equals bp.Id
  select new {
   p,
   bp
  } into t1
 group t1 by t1.p.SomeId into g
 select new ProductPriceMinMax { 
  SomeId = g.FirstOrDefault().p.SomeId, 
  CountryCode = g.FirstOrDefault().p.CountryCode, 
  MinPrice = g.Min(m => m.bp.Price), 
  MaxPrice = g.Max(m => m.bp.Price),
  BaseProductName = g.FirstOrDefault().bp.Name
};

your issue will be resolved by properly defining cascading depedencies or by saving the referenced entities before saving the entity that references. Defining cascading is really tricky to get right because of all the subtle variations in how they are used.

Here is how you can define cascades:

@Entity
public class Userrole implements Serializable {

    private static final long serialVersionUID = 1L;

    @Id
    @GeneratedValue(strategy=GenerationType.AUTO)
    private long userroleid;

    private Timestamp createddate;

    private Timestamp deleteddate;

    private String isactive;

    //bi-directional many-to-one association to Role
    @ManyToOne(cascade = CascadeType.ALL)
    @JoinColumn(name="ROLEID")
    private Role role;

    //bi-directional many-to-one association to User
    @ManyToOne(cascade = CascadeType.ALL)
    @JoinColumn(name="USERID")
    private User user;

}

In this scenario, every time you save, update, delete, etc Userrole, the assocaited Role and User will also be saved, updated...

Again, if your use case demands that you do not modify User or Role when updating Userrole, then simply save User or Role before modifying Userrole

Additionally, bidirectional relationships have a one-way ownership. In this case, User owns Bloodgroup. Therefore, cascades will only proceed from User -> Bloodgroup. Again, you need to save User into the database (attach it or make it non-transient) in order to associate it with Bloodgroup.

Christian's answer works well and shows how you can loop through each hash table item using the GetEnumerator method. You can also loop through using the keys property. Here is an example how:

$hash = @{
    a = 1
    b = 2
    c = 3
}
$hash.Keys | % { "key = $_ , value = " + $hash.Item($_) }

Output:

key = c , value = 3
key = a , value = 1
key = b , value = 2

The fetch mode only says that the association must be fetched. If you want to add restrictions on an associated entity, you must create an alias, or a subcriteria. I generally prefer using aliases, but YMMV:

Criteria c = session.createCriteria(Dokument.class, "dokument");
c.createAlias("dokument.role", "role"); // inner join by default
c.createAlias("role.contact", "contact");
c.add(Restrictions.eq("contact.lastName", "Test"));
return c.list();

This is of course well explained in the Hibernate reference manual, and the javadoc for Criteria even has examples. Read the documentation: it has plenty of useful information.

I had the same problem and in my case the problem was missing and/or incorrect equals implementation on some types of fields in the entity object. At commit time, Hibernate checks ALL entities loaded in the session to check if they are dirty. If any of the entities are dirty, hibernate tries to persist them - no matter of the fact that the actual object that is requested a save operation is not related to the other entities.

Entity dirtiness is done by comparing every property of given object (with their equals methods) or UserType.equals if property has an associated org.Hibernate.UserType.

Another thing that surprised me was, in my transaction (using Spring annotation @Transactional), I was dealing with a single entity. Hibernate was complaining about some random entity that's unrelated to that entity being saved. What I realized is there is an outermost transaction we create at REST controller level, so the scope of the session is too big and hence all objects ever loaded as part of request processing get checked for dirtiness.

Hope this helps someone, some day.

Thanks Rags

If you do not copy and paste the full file path addess e.g. C:\Program Files\Git\bin\git.exe, in the 'path to executable' field when configuring Git, it can lead to errors. Windows 8 & 10 for instance have a 'copy path' functionality which really works and helps to get full path name. Mac should have something similar. Its always best to use that rather clicking in the path address address bar and copying. This does not usually give the full file path and may cause a lot of troubles if you forget to edit the path at its destination.

Path copycopy is also very good add-on for copying full path

To make it work you only need two things. Check if you are missing:

1. First of all, you need @XmlRootElement annotation for your object class/entity.

2. You need to add dependency for jersey-json if you are missing.For your reference I added this dependency into my pom.xml.

   <dependency>
       <groupId>com.sun.jersey</groupId>
       <artifactId>jersey-json</artifactId>
       <version>1.17.1</version>
   </dependency>
   

    if ($.inArray('yourElement', yourArray) > -1)
    {
        //yourElement in yourArray
        //code here

    }

Reference: Jquery Array

The $.inArray() method is similar to JavaScript's native .indexOf() method in that it returns -1 when it doesn't find a match. If the first element within the array matches value, $.inArray() returns 0.

I did try using a Monitor (code below) which appears to work but has a GOTCHA... when you have multiple threads it will give... System.Threading.SynchronizationLockException Object synchronization method was called from an unsynchronized block of code.

using System;
using System.Threading;
using System.Threading.Tasks;

namespace MyNamespace
{
    public class ThreadsafeFooModifier : 
    {
        private readonly object _lockObject;

        public async Task<FooResponse> ModifyFooAsync()
        {
            FooResponse result;
            Monitor.Enter(_lockObject);
            try
            {
                result = await SomeFunctionToModifyFooAsync();
            }
            finally
            {
                Monitor.Exit(_lockObject);
            }
            return result;
        }
    }
}

Prior to this I was simply doing this, but it was in an ASP.NET controller so it resulted in a deadlock.

public async Task<FooResponse> ModifyFooAsync() { lock(lockObject) { return SomeFunctionToModifyFooAsync.Result; } }

This is the right answer http://stackoverflow.com/questions/6990767/inject-bean-reference-into-a-quartz-job-in-spring/15211030#15211030. and will work for most of the folks. But if your web.xml does is not aware of all applicationContext.xml files, quartz job will not be able to invoke those beans. I had to do an extra layer to inject additional applicationContext files

public class MYSpringBeanJobFactory extends SpringBeanJobFactory
        implements ApplicationContextAware {

    private transient AutowireCapableBeanFactory beanFactory;

    @Override
    public void setApplicationContext(final ApplicationContext context) {

        try {
                PathMatchingResourcePatternResolver pmrl = new PathMatchingResourcePatternResolver(context.getClassLoader());
                Resource[] resources = new Resource[0];
                GenericApplicationContext createdContext = null ;
                    resources = pmrl.getResources(
                            "classpath*:my-abc-integration-applicationContext.xml"
                    );

                    for (Resource r : resources) {
                        createdContext = new GenericApplicationContext(context);
                        XmlBeanDefinitionReader reader = new XmlBeanDefinitionReader(createdContext);
                        int i = reader.loadBeanDefinitions(r);
                    }

            createdContext.refresh();//important else you will get exceptions.
            beanFactory = createdContext.getAutowireCapableBeanFactory();

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



    }

    @Override
    protected Object createJobInstance(final TriggerFiredBundle bundle)
            throws Exception {
        final Object job = super.createJobInstance(bundle);
        beanFactory.autowireBean(job);
        return job;
    }
}

You can add any number of context files you want your quartz to be aware of.

[averagRatioArray addObject:[NSString stringWithFormat:@"When you respond Yes to %@ the average response to    %@ was %0.02f",QString1,QString2,M1]];
[averagRatioArray addObject:[NSString stringWithFormat:@"When you respond No  to %@ the average response to    %@ was %0.02f",QString1,QString2,M0]];

UIFont *font2 = [UIFont fontWithName:@"Helvetica-Bold" size:15];
UIFont *font = [UIFont fontWithName:@"Helvetica-Bold" size:12];

NSMutableAttributedString *str=[[NSMutableAttributedString alloc] initWithString:[NSString stringWithFormat:@"When you respond Yes to %@ the average response to %@ was",QString1,QString2]];
[str addAttribute:NSFontAttributeName value:font range:NSMakeRange(0,[@"When you respond Yes to " length])];
[str addAttribute:NSFontAttributeName value:font2 range:NSMakeRange([@"When you respond Yes to " length],[QString1 length])];
[str addAttribute:NSFontAttributeName value:font range:NSMakeRange([QString1 length],[@" the average response to " length])];
[str addAttribute:NSFontAttributeName value:font2 range:NSMakeRange([@" the average response to " length],[QString2 length])];
[str addAttribute:NSFontAttributeName value:font range:NSMakeRange([QString2 length] ,[@" was" length])];
// [str addAttribute:NSFontAttributeName value:font2 range:NSMakeRange(49+[QString1 length]+[QString2 length] ,8)];
[averagRatioArray addObject:[NSString stringWithFormat:@"%@",str]];

As nobody answer, I try something :

I think I understand why Attent one does not work. It's because joining a computer to a domain is somehow also renaming the computer (the domain name part, enter in the name of the machine).

So do you try to do it in full WMI way, you've got a method in Win32_ComputerSystem class called JoinDomainOrWorkgroup. Doing it on the same level perhaps gives you more chance to make it work.

What do they do:

• Internally both do the same thing.

What's the difference:

• WaitAll is a blocking call
• WhenAll - not - code will continue executing

Use which when:

• WaitAll when cannot continue without having the result
• WhenAll when what just to be notified, not blocked

I am using web service in my tool, where those service fetch the stored procedure. while more number of client tool fetches the web service, this problem arises. I have fixed by specifying the Synchronized attribute for those function fetches the stored procedure. now it is working fine, the error never showed up in my tool.

 [MethodImpl(MethodImplOptions.Synchronized)]
 public static List<t> MyDBFunction(string parameter1)
  {
  }

This attribute allows to process one request at a time. so this solves the Issue.

you have to iterate gridview Rows

for (int count = 0; count < grd.Rows.Count; count++)
{
    if (((CheckBox)grd.Rows[count].FindControl("yourCheckboxID")).Checked)
    {     
      ((Label)grd.Rows[count].FindControl("labelID")).Text
    }
}

I also faced this problem . You can try any of these steps :

• Try to kill that process
• Check whether another tomcat instance is running in your machine or not. ( use : ps -A )

first, go to the form load where your comboBox is located,

then try this code

comboBox1.SelectedValue = 0; //shows the 1st item in your collection

if you are using netbeans you must add Mysql JDBC driver in the library list of the project, in the properties of your project

Why not just:

IF object_id('YourFunctionName', 'FN') IS NOT NULL
BEGIN
    DROP FUNCTION [dbo].[YourFunctionName]
END
GO

The second argument of object_id is optional, but can help to identify the correct object. There are numerous possible values for this type argument, particularly:

• FN : Scalar function
• IF : Inline table-valued function
• TF : Table-valued-function
• FS : Assembly (CLR) scalar-function
• FT : Assembly (CLR) table-valued function

Your code doesn't do what you might think it does. Async methods return immediately after the method begins waiting for the async result. It's insightful to use tracing in order to investigate how the code is actually behaving.

The code below does the following:

• Create 4 tasks
• Each task will asynchronously increment a number and return the incremented number
• When the async result has arrived it is traced.

static TypeHashes _type = new TypeHashes(typeof(Program));        
private void Run()
{
    TracerConfig.Reset("debugoutput");

    using (Tracer t = new Tracer(_type, "Run"))
    {
        for (int i = 0; i < 4; i++)
        {
            DoSomeThingAsync(i);
        }
    }
    Application.Run();  // Start window message pump to prevent termination
}


private async void DoSomeThingAsync(int i)
{
    using (Tracer t = new Tracer(_type, "DoSomeThingAsync"))
    {
        t.Info("Hi in DoSomething {0}",i);
        try
        {
            int result = await Calculate(i);
            t.Info("Got async result: {0}", result);
        }
        catch (ArgumentException ex)
        {
            t.Error("Got argument exception: {0}", ex);
        }
    }
}

Task<int> Calculate(int i)
{
    var t = new Task<int>(() =>
    {
        using (Tracer t2 = new Tracer(_type, "Calculate"))
        {
            if( i % 2 == 0 )
                throw new ArgumentException(String.Format("Even argument {0}", i));
            return i++;
        }
    });
    t.Start();
    return t;
}

You will notice that the Run method completes on thread 2820 while only one child thread has finished (2756). If you put a try/catch around your await method you can "catch" the exception in the usual way although your code is executed on another thread when the calculation task has finished and your contiuation is executed.

The calculation method traces the thrown exception automatically because I did use the ApiChange.Api.dll from the ApiChange tool. Tracing and Reflector helps a lot to understand what is going on. To get rid of threading you can create your own versions of GetAwaiter BeginAwait and EndAwait and wrap not a task but e.g. a Lazy and trace inside your own extension methods. Then you will get much better understanding what the compiler and what the TPL does.

Now you see that there is no way to get in a try/catch your exception back since there is no stack frame left for any exception to propagate from. Your code might be doing something totally different after you did initiate the async operations. It might call Thread.Sleep or even terminate. As long as there is one foreground thread left your application will happily continue to execute asynchronous tasks.

You can handle the exception inside the async method after your asynchronous operation did finish and call back into the UI thread. The recommended way to do this is with TaskScheduler.FromSynchronizationContext. That does only work if you have an UI thread and it is not very busy with other things.

Tomcat-7 JNDI configuration:

Steps:

1. Open the server.xml in the tomcat-dir/conf
2. Add below <Resource> tag with your DB details inside <GlobalNamingResources>

<Resource name="jdbc/mydb"
          global="jdbc/mydb"
          auth="Container"
          type="javax.sql.DataSource"
          driverClassName="com.mysql.jdbc.Driver"
          url="jdbc:mysql://localhost:3306/test"
          username="root"
          password=""
          maxActive="10"
          maxIdle="10"
          minIdle="5"
          maxWait="10000"/>

3. Save the server.xml file
4. Open the context.xml in the tomcat-dir/conf
5. Add the below <ResourceLink> inside the <Context> tag.

<ResourceLink name="jdbc/mydb" 
              global="jdbc/mydb"
              auth="Container"
              type="javax.sql.DataSource" />

6. Save the context.xml
7. Open the hibernate-cfg.xml file and add and remove below properties.

Adding:
-------
<property name="connection.datasource">java:comp/env/jdbc/mydb</property>

Removing:
--------
<!--<property name="connection.url">jdbc:mysql://localhost:3306/mydb</property> -->
<!--<property name="connection.username">root</property> -->
<!--<property name="connection.password"></property> -->

8. Save the file and put latest .WAR file in tomcat.
9. Restart the tomcat. the DB connection will work.

I did mine with EF 6.x like this:

using(var db = new ProFormDbContext())
            {
                var Action = 1; 
                var xNTID = "A239333";

                var userPlan = db.Database.SqlQuery<UserPlan>(
                "AD.usp_UserPlanInfo @Action, @NTID", //, @HPID",
                new SqlParameter("Action", Action),
                new SqlParameter("NTID", xNTID)).ToList();


            }

Don't double up on sqlparameter some people get burned doing this to their variable

var Action = new SqlParameter("@Action", 1);  // Don't do this, as it is set below already.

You need to use .each:

var listItems = $("#productList li");
listItems.each(function(idx, li) {
    var product = $(li);

    // and the rest of your code
});

This is the correct way to loop through a jQuery selection.

In modern Javascript you can also use a for .. of loop:

var listItems = $("#productList li");
for (let li of listItems) {
    let product = $(li);
}

Be aware, however, that older browsers will not support this syntax, and you may well be better off with the jQuery syntax above.

The just above code is incorrect as shown:

SELECT 
    sysobjects.name AS trigger_name 
    --,USER_NAME(sysobjects.uid) AS trigger_owner 
    --,s.name AS table_schema 
    --,OBJECT_NAME(parent_obj) AS table_name 
    --,OBJECTPROPERTY( id, 'ExecIsUpdateTrigger') AS isupdate 
    --,OBJECTPROPERTY( id, 'ExecIsDeleteTrigger') AS isdelete 
    --,OBJECTPROPERTY( id, 'ExecIsInsertTrigger') AS isinsert 
    --,OBJECTPROPERTY( id, 'ExecIsAfterTrigger') AS isafter 
    --,OBJECTPROPERTY( id, 'ExecIsInsteadOfTrigger') AS isinsteadof 
    --,OBJECTPROPERTY(id, 'ExecIsTriggerDisabled') AS [disabled] 
FROM sysobjects 
/*
INNER JOIN sysusers 
    ON sysobjects.uid = sysusers.uid 
*/  
INNER JOIN sys.tables t 
    ON sysobjects.parent_obj = t.object_id 

INNER JOIN sys.schemas s 
    ON t.schema_id = s.schema_id 
WHERE sysobjects.type = 'TR' 
EXCEPT
SELECT OBJECT_NAME(parent_id) as Table_Name FROM sys.triggers

In my case, It was from Stored Producers. I was removed a field from table and forgotten to remove it from my SP.

I've had this issue especially when entities are mashalled by Jaxb + Jax-rs. I've used the pre-fetch strategy, but I have also found it effective to provide two entities:

1. Full-blown entity with all collections mapped as EAGER
2. Simplified entity with most or all collections trimmed out

Common fields and be mapped in @MappedSuperclass and extended by both entity implementations.

Certainly if you always need the collections loaded, then there is no reason to not to EAGER load them. In my case I wanted a stripped down version of the entity to display in a grid.

I had a similar problem with a different cause and therefore different solution. In my case, I actually had an error where a singleton object was having a member variable modified in a non-threadsafe way. In this case, following the accepted answers and circumventing the parallel testing would only hide the error that was actually revealed by the test. My solution, of course, is to fix the design so that I don't have this bad behavior in my code.

You can add the id="MyID123" at the start of the cartHTML text appends.

The first line would therefore be:

var cartHTML = '<div id="MyID123" class="soft_add_wrapper" onmouseover="setTimer();">';

-OR-

If you want the ID to be in a variable, then something like this:

    var MyIDvariable = "MyID123";
    var cartHTML = '<div id="'+MyIDvariable+'" class="soft_add_wrapper" onmouseover="setTimer();">';
/* ... the rest of your code ... */

With VisualStudio 2012 there is a way to handle subj without publish profiles. You can pass output folder using parameters. It works both with absolute and relative path in 'publishUrl' parameter. You can use VS100COMNTOOLS, however you need to override VisualStudioVersion to use target 'WebPublish' from %ProgramFiles%\MSBuild\Microsoft\VisualStudio\v11.0\WebApplications\Microsoft.WebApplication.targets. With VisualStudioVersion 10.0 this script will succeed with no outputs :)

Update: I've managed to use this method on a build server with just Windows SDK 7.1 installed (no Visual Studio 2010 and 2012 on a machine). But I had to follow these steps to make it work:

1. Make Windows SDK 7.1 current on a machine using Simmo answer (https://stackoverflow.com/a/2907056/2164198)
2. Setting Registry Key HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\VisualStudio\SxS\VS7\10.0 to "C:\Program Files\Microsoft Visual Studio 10.0\" (use your path as appropriate)
3. Copying folder %ProgramFiles%\MSBuild\Microsoft\VisualStudio\v11.0 from my developer machine to build server

Script:

set WORK_DIR=%~dp0
pushd %WORK_DIR%
set OUTPUTS=%WORK_DIR%..\Outputs
set CONFIG=%~1
if "%CONFIG%"=="" set CONFIG=Release
set VSTOOLS="%VS100COMNTOOLS%"
if %VSTOOLS%=="" set "PATH=%PATH%;%WINDIR%\Microsoft.NET\Framework\v4.0.30319" && goto skipvsinit
call "%VSTOOLS:~1,-1%vsvars32.bat"
if errorlevel 1 goto end
:skipvsinit
msbuild.exe Project.csproj /t:WebPublish /p:Configuration=%CONFIG% /p:VisualStudioVersion=11.0 /p:WebPublishMethod=FileSystem /p:publishUrl=%OUTPUTS%\Project
if errorlevel 1 goto end
:end

I was facing same issue. The code was working in the testing environment. But it was not working in staging environment.

org.hibernate.jdbc.BatchedTooManyRowsAffectedException: Batch update returned unexpected row count from update [0]; actual row count: 3; expected: 1

The problem was the table had single entry for each primary key in testing DB table. But in staging DB there was multiple entry for same primary key. ( Problem is in staging DB the table didn't had any primary key constraints also there was multiple entry.)

So every time on update operation it gets failed. It tries to update single record and expect to get update count as 1. But since there was 3 records in the table for the same primary key, The result update count finds 3. Since expected update count and actual result update count didn't match, It throws exception and rolls back.

After the I removed all the records which have duplicate primary key and added primary key constraints. It is working fine.

Hibernate - Batch update returned unexpected row count from update: 0 actual row count: 0 expected: 1

actual row count: 0 // means no record found to update
update: 0 // means no record found so nothing update
expected: 1 // means expected at least 1 record with key in db table.

Here the problem is that the query trying to update a record for some key, But hibernate didn't find any record with the key.

Daniel's answer was good except I had to change this code...

    SchemeRegistry registry = new SchemeRegistry();
    registry.register(new Scheme("http", PlainSocketFactory.getSocketFactory(), 80));
    registry.register(new Scheme("https", sf, 443));

    ClientConnectionManager ccm = new ThreadSafeClientConnManager(params, registry);

to this code...

    ClientConnectionManager ccm = new ThreadSafeClientConnManager(params, registry);
    SchemeRegistry registry = ccm.getShemeRegistry()
    registry.register(new Scheme("http", PlainSocketFactory.getSocketFactory(), 80));
    registry.register(new Scheme("https", sf, 443));

to get it to work.

I recently felt like I had to do this too, but then found another way which possibly makes my code look neater, and uses better OOP.

I have many sibling classes that each implement a certain method doSomething(). In order to access that method, I would have to have an instance of that class first, but I created a superclass for all my sibling classes and now I can access the method from the superclass.

Below I show two ways alternative ways to "dynamic casting".

// Method 1.
mFragment = getFragmentManager().findFragmentByTag(MyHelper.getName(mUnitNum));
switch (mUnitNum) {
case 0:
    ((MyFragment0) mFragment).sortNames(sortOptionNum);
    break;
case 1:
    ((MyFragment1) mFragment).sortNames(sortOptionNum);
    break;
case 2:
    ((MyFragment2) mFragment).sortNames(sortOptionNum);
    break;
}

and my currently used method,

// Method 2.
mSuperFragment = (MySuperFragment) getFragmentManager().findFragmentByTag(MyHelper.getName(mUnitNum));
mSuperFragment.sortNames(sortOptionNum);

To send a POST request call:

        connection.setDoOutput(true); // Triggers POST.

If you want to sent text in the request use:

        java.io.OutputStreamWriter wr = new java.io.OutputStreamWriter(connection.getOutputStream());
        wr.write(textToSend);
        wr.flush();

SIMPLE ANSWER:

   onclick="functionName(ID.value);

Where ID is the ID of the input field.

You should never use select(), or text(), or radio() etc.; it's terrible practice. You should use input():

$form->input('tree_id', array('options' => $trees));

Then in the controller:

$this->data['Leaf']['tree_id'] = $id;

declare @table_name nvarchar(100)
declare @col_name nvarchar(100)
declare @constraint nvarchar(100)
set @table_name = N'TableName'
set @col_name = N'ColumnName'

IF EXISTS (select       c.*
    from        sys.columns c 
    inner join  sys.tables t on t.object_id = c.object_id
    where       t.name = @table_name
    and         c.name = @col_name) 
BEGIN

select @constraint=d.name
from 
sys.tables t
join sys.default_constraints d on d.parent_object_id = t.object_id
join sys.columns c on c.object_id = t.object_id
and c.column_id = d.parent_column_id
where 
t.name = @table_name
and c.name = @col_name

    IF LEN(ISNULL(@constraint, '')) <> 0
    BEGIN
        DECLARE @sqlcmd VARCHAR(MAX)
        SET @sqlcmd = 'ALTER TABLE ' + QUOTENAME(@table_name) + ' DROP CONSTRAINT' + 
        QUOTENAME(@constraint);
        EXEC (@sqlcmd);

    END

END

I think the best way is to keep the MVVM principle clean, so basically you must use the Messenger Class provided with the MVVM Light and here is how to use it:

in your viewmodel(exampleViewModel.cs):write the following

 Messenger.Default.Send<string>("focus", "DoFocus");

now in your View.cs(not the XAML the view.xaml.cs) write the following in the constructor

 public MyView()
        {
            InitializeComponent();

            Messenger.Default.Register<string>(this, "DoFocus", doFocus);
        }
        public void doFocus(string msg)
        {
            if (msg == "focus")
                this.txtcode.Focus();
        }

that method owrks just fine and with less code and maintaining MVVM standards

I am really new to PowerShell, and I was searching about gmailing from PowerShell. I took what you folks did in previous answers, and modified it a bit and have come up with a script which will check for attachments before adding them, and also to take an array of recipients.

If you're using the EntityDataSource in your project, the solution is in Fix: 'Unable to load one or more of the requested types' Errors. You should set the ContextTypeName="ProjectNameNameSpace.EntityContainerName" '

This solved my problems...

Bringing this back from the dead again. I got around a similar credentials problem by wrapping the .ps1 in a batch file and doing the Win7, Shift + r.Click RunAs. If you wanted to, you can also use PsExec thus:

psexec.exe /accepteula /h /u user /p pwd cmd /c "echo. | powershell.exe -File script.ps1"

Try either CopyOnWriteArrayList or CopyOnWriteArraySet depending on what you are trying to do.

See if it works if you just remove the DbType="Guid" from the markup.

I was facing similar problem and to my surprise the problem was in the version of Java. java.sql.DriverManager comes from rt.jar was unable to load my driver "COM.ibm.db2.jdbc.app.DB2Driver".

I upgraded from jdk 5 and jdk 6 and it worked.

change

select op) 

to

select new { op, pg })

You can use apply for this, and it's a bit neater:

import numpy as np
import pandas as pd

np.random.seed(1)

df = pd.DataFrame(np.random.randn(4,4)* 4 + 3)

          0         1         2         3
0  9.497381  0.552974  0.887313 -1.291874
1  6.461631 -6.206155  9.979247 -0.044828
2  4.276156  2.002518  8.848432 -5.240563
3  1.710331  1.463783  7.535078 -1.399565

df.apply(lambda x: (x - np.mean(x)) / (np.max(x) - np.min(x)))

          0         1         2         3

3 -0.484913  0.244924  0.079473  0.114448

Also, it works nicely with groupby, if you select the relevant columns:

df['grp'] = ['A', 'A', 'B', 'B']

          0         1         2         3 grp
0  9.497381  0.552974  0.887313 -1.291874   A

2  4.276156  2.002518  8.848432 -5.240563   B
3  1.710331  1.463783  7.535078 -1.399565   B


df.groupby(['grp'])[[0,1,2,3]].apply(lambda x: (x - np.mean(x)) / (np.max(x) - np.min(x)))

     0    1    2    3
0  0.5  0.5 -0.5 -0.5
1 -0.5 -0.5  0.5  0.5
2  0.5  0.5  0.5 -0.5
3 -0.5 -0.5 -0.5  0.5

What you are looking for is a query with WITH clause, if your dbms supports it. Then

WITH NewScores AS (
    SELECT * 
    FROM Score  
    WHERE InsertedDate >= DATEADD(mm, -3, GETDATE())
)
SELECT 
<and the rest of your query>
;

Note that there is no ; in the first half. HTH.

Go to project properties -> configurations properties -> C/C++ -> treats warning as error -> No (/WX-).

Maybe this could help you:

=IF(N6<10,"0-10",IF(N6<20,"10-20",IF(N6<30,"20-30",IF(N6<40,"30-40",IF(N6<50,"40-50")))))

Just replace the values and the text to small, medium and large.

All you need is in the documentation.

import time
time.strftime('%X %x %Z')
'16:08:12 05/08/03 AEST'

You can do something like this.

Select distinct name from  (SELECT r.name FROM outsider_role_mapping orm1 
    union all
SELECT r.name FROM user_role_mapping orm2
) tmp;

Found these docu on the google docu pages:

• row --- int --- top row of the range
• column --- int--- leftmost column of the range
• optNumRows --- int --- number of rows in the range.
• optNumColumns --- int --- number of columns in the range

In your example, you would get (if you picked the 3rd row) "C3:O3", cause C --> O is 12 columns

edit

Using the example on the docu:

// The code below will get the number of columns for the range C2:G8
// in the active spreadsheet, which happens to be "4"
var count = SpreadsheetApp.getActiveSheet().getRange(2, 3, 6, 4).getNumColumns(); Browser.msgBox(count);

The values between brackets:
2: the starting row = 2
3: the starting col = C
6: the number of rows = 6 so from 2 to 8
4: the number of cols = 4 so from C to G

So you come to the range: C2:G8

Here are the exact steps I just took to run the "Hello World" example found at http://nodejs.org/. This is a quick and dirty example. For a permanent installation you'd want to store the executable in a more reasonable place than the root directory and update your PATH to include its location.

1. Download the Windows executable here: http://nodejs.org/#download
2. Copy the file to C:\
3. Create C:\hello.js
4. Paste in the following content:

    var http = require('http');
    http.createServer(function (req, res) {
      res.writeHead(200, {'Content-Type': 'text/plain'});
      res.end('Hello World\n');
    }).listen(1337, "127.0.0.1");
    console.log('Server running at http://127.0.0.1:1337/');

1. Save the file
2. Start -> Run... -> cmd
3. c:

4. C:>node hello.js

   Server running at http://127.0.0.1:1337/
   

That's it. This was done on Windows XP.

Use

btnTest_Click( this, new EventArgs() );

See ?substring.

x <- 'hello stackoverflow'
substring(x, 1, 1)
## [1] "h"
substring(x, 2)
## [1] "ello stackoverflow"

The idea of having a pop method that both returns a value and has a side effect of updating the data stored in x is very much a concept from object-oriented programming. So rather than defining a pop function to operate on character vectors, we can make a reference class with a pop method.

PopStringFactory <- setRefClass(
  "PopString",
  fields = list(
    x = "character"  
  ),
  methods = list(
    initialize = function(x)
    {
      x <<- x
    },
    pop = function(n = 1)
    {
      if(nchar(x) == 0)
      {
        warning("Nothing to pop.")
        return("")
      }
      first <- substring(x, 1, n)
      x <<- substring(x, n + 1)
      first
    }
  )
)

x <- PopStringFactory$new("hello stackoverflow")
x
## Reference class object of class "PopString"
## Field "x":
## [1] "hello stackoverflow"
replicate(nchar(x$x), x$pop())
## [1] "h" "e" "l" "l" "o" " " "s" "t" "a" "c" "k" "o" "v" "e" "r" "f" "l" "o" "w"

Assuming there are two dictionaries with exact same keys, below is the most succinct way of doing it (python3 should be used for both the solution).

d1 = {'a': 1, 'b': 2, 'c':3}
d2 = {'a': 5, 'b': 6, 'c':7} 

# get keys from one of the dictionary
ks = [k for k in d1.keys()]

print(ks)
['a', 'b', 'c']

# call values from each dictionary on available keys
d_merged = {k: (d1[k], d2[k]) for k in ks}

print(d_merged)
{'a': (1, 5), 'b': (2, 6), 'c': (3, 7)}

# to merge values as list
d_merged = {k: [d1[k], d2[k]] for k in ks}
print(d_merged)
{'a': [1, 5], 'b': [2, 6], 'c': [3, 7]}

If there are two dictionaries with some common keys, but a few different keys, a list of all the keys should be prepared.

d1 = {'a': 1, 'b': 2, 'c':3, 'd': 9}
d2 = {'a': 5, 'b': 6, 'c':7, 'e': 4} 

# get keys from one of the dictionary
d1_ks = [k for k in d1.keys()]
d2_ks = [k for k in d2.keys()]

all_ks = set(d1_ks + d2_ks)

print(all_ks)
['a', 'b', 'c', 'd', 'e']

# call values from each dictionary on available keys
d_merged = {k: [d1.get(k), d2.get(k)] for k in all_ks}

print(d_merged)
{'d': [9, None], 'a': [1, 5], 'b': [2, 6], 'c': [3, 7], 'e': [None, 4]}

Try a \<Space> before 12, like so:

:set guifont=Monospace\ 12

"Server not found in Kerberos database" error can happen if you have registered the SPN to multiple users/computers.

Above, Abhishek mentions the command line differences specified in two URLS:

1. PhoneGap: http://docs.phonegap.com/en/edge/guide_cli_index.md.html

2. Cordova: http://cordova.apache.org/docs/en/3.0.0/guide_cli_index.md.html#The%20Command-line%20Interface

One thing to point out is that, as of this post, the phonegap one looks to be almost the same as the cordova one, and is probably not an accurate image of the command line option differences. As such, I installed both on my system so I could look at the differences.

These are just a few of them. Hopefully they are brought more in sync sometime. If anyone has better information, please tell me.

1. Adding platforms seems to be done differently between the two commands ( phonegap uses "install" command, cordova uses "platform add" command )
2. Adding/creating projects seems to be the same between the two commands ( same command line options supported )
3. Obviously, as has been stated, phonegap can use PhoneGap Build, so it has the corresponding options to trigger that or local builds
4. Quite a few other significant command line differences, simply by running "cordova help" and "phonegap help" and comparing the two.

I guess my point is that the phonegap CLI documention mentioned quite often is not really for the phonegap CLI, but for the cordova CLI, at this time. Please tell me if I am missing something. Thanks.

I know you're interested in Integer numbers so I won't re answer that but if you ever wanted to check for Floating Point numbers you could do this.

function isFloat( x )
{
    return ( typeof x === "number" && Math.abs( x % 1 ) > 0);
}

Note: This MAY treat numbers ending in .0 (or any logically equivalent number of 0's) as an INTEGER. It actually needs a floating point precision error to occur to detect the floating point values in that case.

Ex.

alert(isFloat(5.2));   //returns true
alert(isFloat(5));     //returns false
alert(isFloat(5.0));   //return could be either true or false

Hope it helps.

Expanding on @rado's answer above one could also use a ternary statement to force the return of true or false booleans without the use of double bangs. Granted, the double logical negation version is more terse, but probably harder to read for newcomers (like me).

class String
  def is_i?
     self =~ /\A[-+]?[0-9]+\z/ ? true : false
  end
end

No, this will cause the exception to have a different stack trace. Only using a throw without any exception object in the catch handler will leave the stack trace unchanged.

You may want to return a boolean from HandleException whether the exception shall be rethrown or not.

Also wanted to add this (Python 3.7)

import json

with open("dict_to_json_textfile.txt", 'w') as fout:
    json_dumps_str = json.dumps(a_dictionary, indent=4)
    print(json_dumps_str, file=fout)

This should do what you're looking for.

I have come accross the above issue. I have solved it as below. Its working fine for me.

1. Download the 'org.apache.commons.io.jar' file on navigating to [org.apache.commons.io.FileUtils] [ http://www.java2s.com/Code/Jar/o/Downloadorgapachecommonsiojar.htm ]

2. Extract the downloaded zip file to a specified folder.

3. Update the project properties by using below navigation Right click on project>Select Properties>Select Java Build Path> Click Libraries tab>Click Add External Class Folder button>Select the folder where zip file is extracted for org.apache.commons.io.FileUtils.zip file.

4. Now access the File Utils.

Beware of sample for splitting if you look for reproducible results. If your data changes even slightly, the split will vary even if you use set.seed. For example, imagine the sorted list of IDs in you data is all the numbers between 1 and 10. If you just dropped one observation, say 4, sampling by location would yield a different results because now 5 to 10 all moved places.

An alternative method is to use a hash function to map IDs into some pseudo random numbers and then sample on the mod of these numbers. This sample is more stable because assignment is now determined by the hash of each observation, and not by its relative position.

For example:

require(openssl)  # for md5
require(data.table)  # for the demo data

set.seed(1)  # this won't help `sample`

population <- as.character(1e5:(1e6-1))  # some made up ID names

N <- 1e4  # sample size

sample1 <- data.table(id = sort(sample(population, N)))  # randomly sample N ids
sample2 <- sample1[-sample(N, 1)]  # randomly drop one observation from sample1

# samples are all but identical
sample1
sample2
nrow(merge(sample1, sample2))

[1] 9999

# row splitting yields very different test sets, even though we've set the seed
test <- sample(N-1, N/2, replace = F)

test1 <- sample1[test, .(id)]
test2 <- sample2[test, .(id)]
nrow(test1)

[1] 5000

nrow(merge(test1, test2))

[1] 2653

# to fix that, we can use some hash function to sample on the last digit

md5_bit_mod <- function(x, m = 2L) {
  # Inputs: 
  #  x: a character vector of ids
  #  m: the modulo divisor (modify for split proportions other than 50:50)
  # Output: remainders from dividing the first digit of the md5 hash of x by m
  as.integer(as.hexmode(substr(openssl::md5(x), 1, 1)) %% m)
}

# hash splitting preserves the similarity, because the assignment of test/train 
# is determined by the hash of each obs., and not by its relative location in the data
# which may change 
test1a <- sample1[md5_bit_mod(id) == 0L, .(id)]
test2a <- sample2[md5_bit_mod(id) == 0L, .(id)]
nrow(merge(test1a, test2a))

[1] 5057

nrow(test1a)

[1] 5057

sample size is not exactly 5000 because assignment is probabilistic, but it shouldn't be a problem in large samples thanks to the law of large numbers.

Based on @Mahomedalid answer, I have done some improvements to support "select all columns except some in mysql"

SET @database    = 'database_name';
SET @tablename   = 'table_name';
SET @cols2delete = 'col1,col2,col3';

SET @sql = CONCAT(
'SELECT ', 
(
    SELECT GROUP_CONCAT( IF(FIND_IN_SET(COLUMN_NAME, @cols2delete), NULL, COLUMN_NAME ) )
    FROM INFORMATION_SCHEMA.COLUMNS WHERE TABLE_NAME = @tablename AND TABLE_SCHEMA = @database
), 
' FROM ',
@tablename);

SELECT @sql;

If you do have a lots of cols, use this sql to change group_concat_max_len

SET @@group_concat_max_len = 2048;

I could care less about IE6, as long as it works in IE8, Firefox 4, and Safari 5

This makes me happy.

Try this: Live Demo

display: table is surprisingly good. Once you don't care about IE7, you're free to use it. It doesn't really have any of the usual downsides of <table>.

CSS:

#container {
    background: #ccc;
    display: table
}
#left, #right {
    display: table-cell
}
#left {
    width: 150px;
    background: #f0f;
    border: 5px dotted blue;
}
#right {
    background: #aaa;
    border: 3px solid #000
}

I think some code about the cURL solution is needed here, so I will share mine (it was written mixing several sources as the PHP Manual and comments).

It does some parallel HTTP requests (domains in $aURLs) and print the responses once each one is completed (and stored them in $done for other possible uses).

The code is longer than needed because the realtime print part and the excess of comments, but feel free to edit the answer to improve it:

<?php
/* Strategies to avoid output buffering, ignore the block if you don't want to print the responses before every cURL is completed */
ini_set('output_buffering', 'off'); // Turn off output buffering
ini_set('zlib.output_compression', false); // Turn off PHP output compression       
//Flush (send) the output buffer and turn off output buffering
ob_end_flush(); while (@ob_end_flush());        
apache_setenv('no-gzip', true); //prevent apache from buffering it for deflate/gzip
ini_set('zlib.output_compression', false);
header("Content-type: text/plain"); //Remove to use HTML
ini_set('implicit_flush', true); // Implicitly flush the buffer(s)
ob_implicit_flush(true);
header('Cache-Control: no-cache'); // recommended to prevent caching of event data.
$string=''; for($i=0;$i<1000;++$i){$string.=' ';} output($string); //Safari and Internet Explorer have an internal 1K buffer.
//Here starts the program output

function output($string){
    ob_start();
    echo $string;
    if(ob_get_level()>0) ob_flush();
    ob_end_clean();  // clears buffer and closes buffering
    flush();
}

    global $done;

If you have not yet committed to your local repo, there is nothing to push, but the Git error message you get back doesn't help you too much.

If you're using docker for windows, remember that you have to change your line-ending format from CRLF to LF (i.e. from dos to unix) if you intend on importing your crontab file from windows to your ubuntu container. If not, your cron-job won't work. Here's a working example:

FROM ubuntu:latest

RUN apt-get update && apt-get -y install cron
RUN apt-get update && apt-get install -y dos2unix

# Add crontab file (from your windows host) to the cron directory
ADD cron/hello-cron /etc/cron.d/hello-cron

# Change line ending format to LF
RUN dos2unix /etc/cron.d/hello-cron

# Give execution rights on the cron job
RUN chmod 0644 /etc/cron.d/hello-cron

# Apply cron job
RUN crontab /etc/cron.d/hello-cron

# Create the log file to be able to run tail
RUN touch /var/log/hello-cron.log

# Run the command on container startup
CMD cron && tail -f /var/log/hello-cron.log

This actually took me hours to figure out, as debugging cron jobs in docker containers is a tedious task. Hope it helps anyone else out there that can't get their code to work!

I faced same issue on Linux when I installed docker using yum (yum install docker).

Resolution: download docker binary from official site: docker install, unpack and follow the installation steps.

If you want to bring information from a database into a textarea tag for editing: The input tag not to display data that occupy several lines: rows no work, tag input is one line.

<!--input class="article-input" id="article-input" type="text" rows="5" value="{{article}}" /-->

The textarea tag has no value, but work fine with handlebars

<textarea class="article-input" id="article-input" type="text" rows="9" >{{article}}</textarea> 

A negative lookahead says, at this position, the following regex can not match.

Let's take a simplified example:

a(?!b(?!c))

a      Match: (?!b) succeeds
ac     Match: (?!b) succeeds
ab     No match: (?!b(?!c)) fails
abe    No match: (?!b(?!c)) fails
abc    Match: (?!b(?!c)) succeeds

The last example is a double negation: it allows a b followed by c. The nested negative lookahead becomes a positive lookahead: the c should be present.

In each example, only the a is matched. The lookahead is only a condition, and does not add to the matched text.

With ANY operator you can search for only one value.

For example,

select * from mytable where 'Book' = ANY(pub_types);

If you want to search multiple values, you can use @> operator.

For example,

select * from mytable where pub_types @> '{"Journal", "Book"}';

You can specify in which ever order you like.

I faced with the same error, when i downloaded the Jmeter Source, and it got fixed once i downloaded Jmeter Binary. Please watch this video.

I was trying to make my module from magaplaza hello world tutorial, but something went wrong. I imported code of this module https://github.com/astorm/magento2-hello-world from github and it worked. from that module, i created it a categories subcategories ajax select drop downs Module. After installing it in aap/code directory of your magento2 installation follow this URL.. http://www.example.com/hello_mvvm/hello/world You can download its code from here https://github.com/sanaullahAhmad/Magento2_cat_subcat_ajax_select_dropdowns and place it in your aap/code folder. than run these commands...

php bin/magento setup:update

$eval and $parse don't evaluate JavaScript; they evaluate AngularJS expressions. The linked documentation explains the differences between expressions and JavaScript.

Q: What exactly is $eval doing? Why does it need its own mini parsing language?

From the docs:

Expressions are JavaScript-like code snippets that are usually placed in bindings such as {{ expression }}. Expressions are processed by $parse service.

It's a JavaScript-like mini-language that limits what you can run (e.g. no control flow statements, excepting the ternary operator) as well as adds some AngularJS goodness (e.g. filters).

Q: Why isn't plain old javascript "eval" being used?

Because it's not actually evaluating JavaScript. As the docs say:

If ... you do want to run arbitrary JavaScript code, you should make it a controller method and call the method. If you want to eval() an angular expression from JavaScript, use the $eval() method.

The docs linked to above have a lot more information.

I think you can get it using subc1.text.

>>> html = """

>>> print soup.text


YOB: 1987

Or if you want to explore it, you can use .contents :

>>> p = soup.find('p')
>>> from pprint import pprint
>>> pprint(p.contents)
[u'\n',
 <strong class="offender">YOB:</strong>,
 u' 1987',

 <strong class="offender">EYE COLOR:</strong>,
 u' GREEN',
 <br/>,
 u'\n',
 <strong class="offender">HAIR COLOR:</strong>,

and filter out the necessary items from the list:

>>> data = dict(zip([x.text for x in p.contents[1::4]], [x.strip() for x in p.contents[2::4]]))
>>> pprint(data)

Why do you need -Xms768 (small heap must be at least 768...)?

That means any java process (search in eclipse) will start with 768m memory allocated, doesn't that? That is why your eclipse isn't able to start properly.

Try -Xms16 -Xmx2048m, for instance.

class foo(object):
    def __str__(self):
        return "representation"
    def __unicode__(self):
        return u"representation"

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

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

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

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

document.getElementsByClassName returns an array of elements. so may be you want to target a specific index of them: var comment = document.getElementsByClassName('button')[0]; should get you what you want.

Update #1:

var comments = document.getElementsByClassName('button');
var numComments = comments.length;

function showComment() {
  var place = document.getElementById('textfield');
  var commentBox = document.createElement('textarea');
  place.appendChild(commentBox);
}

for (var i = 0; i < numComments; i++) {
  comments[i].addEventListener('click', showComment, false);
}

Update #2: (with removeEventListener incorporated as well)

var comments = document.getElementsByClassName('button');
var numComments = comments.length;

function showComment(e) {
  var place = document.getElementById('textfield');
  var commentBox = document.createElement('textarea');
  place.appendChild(commentBox);
  for (var i = 0; i < numComments; i++) {
    comments[i].removeEventListener('click', showComment, false);
  }
}

for (var i = 0; i < numComments; i++) {
  comments[i].addEventListener('click', showComment, false);
}

Combining both answers from

Flo & rptwsthi and roetzi,

Do remember to change your layout_width=0dp/px, else the layout_weight behaviour will act reversely with biggest number occupied the smallest space and lowest number occupied the biggest space.

Besides, some weights combination will caused some layout cannot be shown (since it over occupied the space).

Beware of this.

Try the following:

var div = document.createElement("div");
div.innerHTML = "topdiv";
div.appendChild(element);
document.body.appendChild(div);

You could walk up through the parents, noting their position within their parent, until you arrive at the Form.

Edit: Something like (untested):

public Point GetPositionInForm(Control ctrl)
{
   Point p = ctrl.Location;
   Control parent = ctrl.Parent;
   while (! (parent is Form))
   {
      p.Offset(parent.Location.X, parent.Location.Y);
      parent = parent.Parent;
   }
   return p;
}

untested:

using System;
using System.Management;

ManagementObject disk = new
ManagementObject("win32_logicaldisk.deviceid="c:"");
disk.Get();
Console.WriteLine("Logical Disk Size = " + disk["Size"] + " bytes");
Console.WriteLine("Logical Disk FreeSpace = " + disk["FreeSpace"] + "
bytes"); 

Btw what is the outcome of free diskspace on c:\temp ? you will get the space free of c:\

I use Fedora (currently 31)

Even with JDK's installed, I still need to specify JAVAC_HOME in the .bashrc, especially since I have 4 Java versions using sudo alternatives --configure java to switch between them.

To find java location of java selected in alternatives

readlink -f $(which java)

In my case: /usr/java/jdk1.8.0_241-amd64/jre/bin/java

So I set following in .bashrc to:

export JAVA_HOME=/usr/java/jdk1.8.0_241-amd64/jre/bin/java

export JAVAC_HOME=/usr/java/jdk1.8.0_241-amd64/bin/javac

export PATH=$PATH:/usr/java/jdk1.8.0_241-amd64/jre/bin

export PATH=$PATH:/usr/java/jdk1.8.0_241-amd64/bin/

Now javac –version gives: javac 1.8.0_241

This is useful for those who want to use Oracle's version. Just remember to change your .bashrc again if you make a change with java alternatives.

.text-left {

It can also be done using backtracking by maintaining a visited array.

void foo(vector<vector<int> > &s,vector<int> &data,int go,int k,vector<int> &vis,int tot)
{

    vis[go]=1;
    data.push_back(go);
    if(data.size()==k)
    {
        s.push_back(data);
        vis[go]=0;
    data.pop_back();
        return;
    }

    for(int i=go+1;i<=tot;++i)
    {
       if(!vis[i])
       {
           foo(s,data,i,k,vis,tot);
       }
    }
    vis[go]=0;
    data.pop_back();
}


vector<vector<int> > Solution::combine(int n, int k) {
   vector<int> data;
   vector<int> vis(n+1,0);
   vector<vector<int> > sol;
   for(int i=1;i<=n;++i)
   {
       for(int i=1;i<=n;++i) vis[i]=0;
   foo(sol,data,i,k,vis,n);
   }
   return sol;

json.dumps() returns the JSON string representation of the python dict. See the docs

You can't do r['rating'] because r is a string, not a dict anymore

Perhaps you meant something like

r = {'is_claimed': 'True', 'rating': 3.5}
json = json.dumps(r) # note i gave it a different name
file.write(str(r['rating']))

Let me make it simple.
You can use @JoinColumn on either sides irrespective of mapping.

Let's divide this into three cases.
1) Uni-directional mapping from Branch to Company.
2) Bi-direction mapping from Company to Branch.
3) Only Uni-directional mapping from Company to Branch.

So any use-case will fall under this three categories. So let me explain how to use @JoinColumn and mappedBy.
1) Uni-directional mapping from Branch to Company.
Use JoinColumn in Branch table.
2) Bi-direction mapping from Company to Branch.
Use mappedBy in Company table as describe by @Mykhaylo Adamovych's answer.
3)Uni-directional mapping from Company to Branch.
Just use @JoinColumn in Company table.

@Entity
public class Company {

@OneToMany(cascade = CascadeType.ALL , fetch = FetchType.LAZY)
@JoinColumn(name="courseId")
private List<Branch> branches;
...
}

This says that in based on the foreign key "courseId" mapping in branches table, get me list of all branches. NOTE: you can't fetch company from branch in this case, only uni-directional mapping exist from company to branch.

This will work for junit. for TestNG use following command

-ea -Dmykey="value" -Dmykey2="value2"

Never mind, I found it in the docs:

-g/--globoff
              This  option  switches  off  the "URL globbing parser". When you set this option, you can
              specify URLs that contain the letters {}[] without having them being interpreted by  curl
              itself.  Note  that  these  letters  are not normal legal URL contents but they should be
              encoded according to the URI standard.

SKU stands for Stock-keeping Unit. It's more for inventory tracking purpose.

The purpose of having an SKU is so that you can tie the app sales to whatever internal SKU number that your accounting is using.

1 - add &enablejsapi=1 to IFRAME SRC

2 - jQuery func:

  $('iframe#your_video')[0].contentWindow.postMessage('{"event":"command","func":"playVideo","args":""}', '*');

Works fine

s = "ABCD"
from array import array
a = array("B", s)

If you want hex:

print map(hex, a)

we can simply copy the code from tostring of object class to get the reference of string

class Test
{
  public static void main(String args[])
  {
    String a="nikhil";     // it stores in String constant pool
    String s=new String("nikhil");    //with new stores in heap
    System.out.println(Integer.toHexString(System.identityHashCode(a)));
    System.out.println(Integer.toHexString(System.identityHashCode(s)));
  }
}

1. Right click your project folder.
2. Select Properties.

This is how you should initialize the NSString:

Swift 2.X or older

let datastring = NSString(data: fooData, encoding: NSUTF8StringEncoding)

Swift 3 or newer:

let datastring = NSString(data: fooData, encoding: String.Encoding.utf8.rawValue)

This doc explains the syntax.

If the values are integer then you can use [2-3] or you can use [5,7,8] for non continuous values.

#!/bin/bash
while [ $# -gt 0 ];
do
    case $1 in
    1)
        echo "one"
        ;;
    [2-3])
        echo "two or three"
        ;;
    [4-6])
        echo "four to six"
        ;;
    [7,9])
        echo "seven or nine"
        ;;
    *)
        echo "others"
        ;;
    esac
    shift
done

If the values are string then you can use |.

#!/bin/bash
while [ $# -gt 0 ];
do
    case $1 in
    "one")
        echo "one"
        ;;

According to this : we can write this help function :

    public static int convertBinaryToDecimal(String str) {
        int result = 0;
        for (int i = 0; i < str.length(); i++) {
            int value = Character.getNumericValue(str.charAt(i));
            result = result * 2 + value;
        }
        return result;
    }

Use this function to find all script elements containing some word and refresh them.

Do you mean entirely transparent, or using the translucent-black style seen in the Photos app? The latter you can accomplish by setting its barStyle property to UIBarStyleBlackTranslucent. The former... I'm not sure about. If you want the items on it to still be visible, you might have to do some digging around in the bar's view hierarchy and remove the view containing its background.

Also you should know that you can force TLS v1.2 for Android 4.0 devices that don't have it enabled by default:

Put this code in onCreate() of your Application file:

try {
        ProviderInstaller.installIfNeeded(getApplicationContext());
        SSLContext sslContext;
        sslContext = SSLContext.getInstance("TLSv1.2");
        sslContext.init(null, null, null);
        sslContext.createSSLEngine();
    } catch (GooglePlayServicesRepairableException | GooglePlayServicesNotAvailableException
            | NoSuchAlgorithmException | KeyManagementException e) {
        e.printStackTrace();
    }

Calling EntityManager#flush does have side-effects. It is conveniently used for entity types with generated ID values (sequence values): such an ID is available only upon synchronization with underlying persistence layer. If this ID is required before the current transaction ends (for logging purposes for instance), flushing the session is required.

REST is not a specific web service but a design concept (architecture) for managing state information. The seminal paper on this was Roy Thomas Fielding's dissertation (2000), "Architectural Styles and the Design of Network-based Software Architectures" (available online from the University of California, Irvine).

First read Ryan Tomayko's post How I explained REST to my wife; it's a great starting point. Then read Fielding's actual dissertation. It's not that advanced, nor is it long (six chapters, 180 pages)! (I know you kids in school like it short).

EDIT: I feel it's pointless to try to explain REST. It has so many concepts like scalability, visibility (stateless) etc. that the reader needs to grasp, and the best source for understanding those are the actual dissertation. It's much more than POST/GET etc.

Inside template this working finely.

I'll right simple example show you the right way to use wait and notify in Java. So I'll create two class named ThreadA & ThreadB. ThreadA will call ThreadB.

public class ThreadA {
    public static void main(String[] args){
        ThreadB b = new ThreadB();//<----Create Instance for seconde class
        b.start();//<--------------------Launch thread

        synchronized(b){
            try{
                System.out.println("Waiting for b to complete...");
                b.wait();//<-------------WAIT until the finish thread for class B finish
            }catch(InterruptedException e){
                e.printStackTrace();
            }

            System.out.println("Total is: " + b.total);
        }
    }
} 

and for Class ThreadB:

class ThreadB extends Thread{
    int total;
    @Override
    public void run(){
        synchronized(this){
            for(int i=0; i<100 ; i++){
                total += i;
            }
            notify();//<----------------Notify the class wich wait until my    finish 
//and tell that I'm finish
            }
        }
    }

Try this one:

onsubmit="return f(this.'yourfieldname'.value);"

I hope this will help you.

• You can use pandas.Series.astype

• You can do something like this :

  weather["Temp"] = weather.Temp.astype(float)
  

• You can also use pd.to_numeric that will convert the column from object to float

• For details on how to use it checkout this link :http://pandas.pydata.org/pandas-docs/version/0.20/generated/pandas.to_numeric.html

• Example :

  s = pd.Series(['apple', '1.0', '2', -3])
  print(pd.to_numeric(s, errors='ignore'))
  print("=========================")
  print(pd.to_numeric(s, errors='coerce'))
  

• Output:

  0    apple
  1      1.0
  2        2
  3       -3
  =========================
  dtype: object
  0    NaN
  1    1.0
  2    2.0
  3   -3.0
  dtype: float64
  

• In your case you can do something like this:

  weather["Temp"] = pd.to_numeric(weather.Temp, errors='coerce')
  

• Other option is to use convert_objects

• Example is as follows

  >> pd.Series([1,2,3,4,'.']).convert_objects(convert_numeric=True)
  
  0     1
  1     2
  2     3
  3     4
  4   NaN
  dtype: float64
  

• You can use this as follows:

  weather["Temp"] = weather.Temp.convert_objects(convert_numeric=True)
  

• I have showed you examples because if any of your column won't have a number then it will be converted to NaN... so be careful while using it.

IntStream can be used to access each character and add them to the list.

String str = "abc";
List<Character> charList = new ArrayList<>();
IntStream.range(0,str.length()).forEach(i -> charList.add(str.charAt(i)));

If you have a Floating Action Button with no drawable you can change the tint programmatically using:

fab.getBackground().mutate().setTint(ContextCompat.getColor(yourContext, R.color.anyColor));

If you can't use box-sizing:border-box you could try removing the width:100% and putting a very large size attribute in the <input> element, drawback is however you have to modify the html, and can't do it with CSS only:

<input size="1000"></input>

function addAttr(scope, el, attrName, attrValue) {
  el.replaceWith($compile(el.clone().attr(attrName, attrValue))(scope));
}

Each class will use its own classloader to load other classes. So if ClassA.class references ClassB.class then ClassB needs to be on the classpath of the classloader of ClassA, or its parents.

The thread context classloader is the current classloader for the current thread. An object can be created from a class in ClassLoaderC and then passed to a thread owned by ClassLoaderD. In this case the object needs to use Thread.currentThread().getContextClassLoader() directly if it wants to load resources that are not available on its own classloader.

The terms "stress testing" and "load testing" are often used interchangeably by software test engineers but they are really quite different.

Stress testing

In Stress testing we tries to break the system under test by overwhelming its resources or by taking resources away from it (in which case it is sometimes called negative testing). The main purpose behind this madness is to make sure that the system fails and recovers gracefully -- this quality is known as recoverability. OR Stress testing is the process of subjecting your program/system under test (SUT) to reduced resources and then examining the SUT’s behavior by running standard functional tests. The idea of this is to expose problems that do not appear under normal conditions.For example, a multi-threaded program may work fine under normal conditions but under conditions of reduced CPU availability, timing issues will be different and the SUT will crash. The most common types of system resources reduced in stress testing are CPU, internal memory, and external disk space. When performing stress testing, it is common to call the tools which reduce these three resources EatCPU, EatMem, and EatDisk respectively.

While on the other hand Load Testing

In case of Load testing Load testing is the process of subjecting your SUT to heavy loads, typically by simulating multiple users( Using Load runner), where "users" can mean human users or virtual/programmatic users. The most common example of load testing involves subjecting a Web-based or network-based application to simultaneous hits by thousands of users. This is generally accomplished by a program which simulates the users. There are two main purposes of load testing: to determine performance characteristics of the SUT, and to determine if the SUT "breaks" gracefully or not.

In the case of a Web site, you would use load testing to determine how many users your system can handle and still have adequate performance, and to determine what happens with an extreme load — will the Web site generate a "too busy" message for users, or will the Web server crash in flames?

Use where with a != operator in combination with whereNull

Code::where('to_be_used_by_user_id', '!=' , 2)->orWhereNull('to_be_used_by_user_id')->get()

checked attribute is a boolean value so "checked" value of other "string" except boolean false converts to true.

Any string value will be true. Also presence of attribute make it true:

<input type="checkbox" checked>

You can make it uncheked only making boolean change in DOM using JS.

So the answer is: they are equal.

w3c

editText.setInputType(InputType.TYPE_NULL);

Very simple piece of code to do this

$date - extract(day from $date) + 1

two ways to do this:

1. my_date - extract(day from my_date) + 1

2. '2014/01/21' - extract(day from '2014/01/21') + 1

I assume with the second line you actually mean:

Thing *thing = new Thing("uiae");

which would be the standard way of creating new dynamic objects (necessary for dynamic binding and polymorphism) and storing their address to a pointer. Your code does what JaredPar described, namely creating two objects (one passed a const char*, the other passed a const Thing&), and then calling the destructor (~Thing()) on the first object (the const char* one).

By contrast, this:

Thing thing("uiae");

creates a static object which is destroyed automatically upon exiting the current scope.

Above answers have enough description for the asked question.

Adding to that, Tensorflow has optimised the operation of applying the activation function then calculating cost using its own activation followed by cost functions. Hence it is a good practice to use: tf.nn.softmax_cross_entropy() over tf.nn.softmax(); tf.nn.cross_entropy()

You can find prominent difference between them in a resource intensive model.

The console is not available because the code is running in the cloud, not in your browser. Instead, use the Logger class provided by GAS:

Logger.log(playerArray[3])

and then view the results in the IDE under View > Logs...

Here's some documentation on logging with GAS.

Edit: 2017-07-20 Apps script now also provides Stackdriver Logging. View these logs in the script editor under View - Console Logs.

Not with array_map, as it doesn't handle keys.

array_walk does:

$test_array = array("first_key" => "first_value",
                    "second_key" => "second_value");
array_walk($test_array, function(&$a, $b) { $a = "$b loves $a"; });
var_dump($test_array);

// array(2) {
//   ["first_key"]=>
//   string(27) "first_key loves first_value"
//   ["second_key"]=>
//   string(29) "second_key loves second_value"
// }

It does change the array given as parameter however, so it's not exactly functional programming (as you have the question tagged like that). Also, as pointed out in the comment, this will only change the values of the array, so the keys won't be what you specified in the question.

You could write a function that fixes the points above yourself if you wanted to, like this:

function mymapper($arrayparam, $valuecallback) {
  $resultarr = array();
  foreach ($arrayparam as $key => $value) {
    $resultarr[] = $valuecallback($key, $value);
  }
  return $resultarr;
}

$test_array = array("first_key" => "first_value",
                    "second_key" => "second_value");
$new_array = mymapper($test_array, function($a, $b) { return "$a loves $b"; });
var_dump($new_array);

// array(2) {
//   [0]=>
//   string(27) "first_key loves first_value"
//   [1]=>
//   string(29) "second_key loves second_value"
// }

I solved the problem. I made mistake in setData(Uri) and setType(String).

Intent intent = new Intent(Intent.ACTION_VIEW);
intent.setDataAndType(Uri.fromFile(new File(Environment.getExternalStorageDirectory() + "/download/" + "app.apk")), "application/vnd.android.package-archive");
intent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
startActivity(intent);

That is correct now, my auto-update is working. Thanks for help. =)

Edit 20.7.2016:

After a long time, I had to use this way of updating again in another project. I encountered a number of problems with old solution. A lot of things have changed in that time, so I had to do this with a different approach. Here is the code:

    //get destination to update file and set Uri
    //TODO: First I wanted to store my update .apk file on internal storage for my app but apparently android does not allow you to open and install
    //aplication with existing package from there. So for me, alternative solution is Download directory in external storage. If there is better
    //solution, please inform us in comment
    String destination = Environment.getExternalStoragePublicDirectory(Environment.DIRECTORY_DOWNLOADS) + "/";
    String fileName = "AppName.apk";
    destination += fileName;
    final Uri uri = Uri.parse("file://" + destination);

    //Delete update file if exists
    File file = new File(destination);
    if (file.exists())
    //file.delete() - test this, I think sometimes it doesnt work
        file.delete();

    //get url of app on server
    String url = Main.this.getString(R.string.update_app_url);

    //set downloadmanager
    DownloadManager.Request request = new DownloadManager.Request(Uri.parse(url));
    request.setDescription(Main.this.getString(R.string.notification_description));
    request.setTitle(Main.this.getString(R.string.app_name));

    //set destination
    request.setDestinationUri(uri);

    // get download service and enqueue file
    final DownloadManager manager = (DownloadManager) getSystemService(Context.DOWNLOAD_SERVICE);
    final long downloadId = manager.enqueue(request);

    //set BroadcastReceiver to install app when .apk is downloaded
    BroadcastReceiver onComplete = new BroadcastReceiver() {
        public void onReceive(Context ctxt, Intent intent) {
            Intent install = new Intent(Intent.ACTION_VIEW);
            install.setFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);
            install.setDataAndType(uri,
                    manager.getMimeTypeForDownloadedFile(downloadId));
            startActivity(install);

            unregisterReceiver(this);
            finish();
        }
    };
    //register receiver for when .apk download is compete
    registerReceiver(onComplete, new IntentFilter(DownloadManager.ACTION_DOWNLOAD_COMPLETE));

To be totally exhaustive, things are different if you're using a JPA 1.0 or a JPA 2.0 implementation.

JPA 1.0

With JPA 1.0, you'd have to use EntityManager#getDelegate(). But keep in mind that the result of this method is implementation specific i.e. non portable from application server using Hibernate to the other. For example with JBoss you would do:

org.hibernate.Session session = (Session) manager.getDelegate();

But with GlassFish, you'd have to do:

org.hibernate.Session session = ((org.hibernate.ejb.EntityManagerImpl) em.getDelegate()).getSession(); 

I agree, that's horrible, and the spec is to blame here (not clear enough).

JPA 2.0

With JPA 2.0, there is a new (and much better) EntityManager#unwrap(Class<T>) method that is to be preferred over EntityManager#getDelegate() for new applications.

So with Hibernate as JPA 2.0 implementation (see 3.15. Native Hibernate API), you would do:

Session session = entityManager.unwrap(Session.class);

Another easy way is to use the WC_Product_Factory class and then call function get_product(ID)

http://docs.woothemes.com/wc-apidocs/source-class-WC_Product_Factory.html#16-63

sample:

// assuming the list of product IDs is are stored in an array called IDs;
$_pf = new WC_Product_Factory();  
foreach ($IDs as $id) {

    $_product = $_pf->get_product($id);

    // from here $_product will be a fully functional WC Product object, 
    // you can use all functions as listed in their api
}

You can then use all the function calls as listed in their api: http://docs.woothemes.com/wc-apidocs/class-WC_Product.html

To auto-format the selection, use ?K ?F (the trick is that this is to be done in sequence, ?K first, followed by ?F).

To just indent (shift right) without auto-formatting, use ?]

As in Keyboard Shortcuts (?K ?S, or from the menu as shown below)

Got the same error recently but was able to fixed it by ensuring to close every wcf client call. eg.

WCFServiceClient client = new WCFServiceClient ();
//More codes here
// Always close the client.
client.Close();

or

{ 
    //More codes here 
}

RankoR@ you must have installed the application from a different computer. in my case thats where the problem arose .. all you need to do is just uninstall the application and reinstall it or run it from the computer you are working .. this might be a late reply but it will help some one .. thanks

The first part of your question is a duplicate of Why do I get a JsonReaderException with this code?, but the most relevant part from that (my) answer is this:

[A] JObject isn't the elementary base type of everything in JSON.net, but JToken is. So even though you could say,

object i = new int[0];

in C#, you can't say,

JObject i = JObject.Parse("[0, 0, 0]");

in JSON.net.

What you want is JArray.Parse, which will accept the array you're passing it (denoted by the opening [ in your API response). This is what the "StartArray" in the error message is telling you.

As for what happened when you used JArray, you're using arr instead of obj:

var rcvdData = JsonConvert.DeserializeObject<LocationData>(arr /* <-- Here */.ToString(), settings);

Swap that, and I believe it should work.

Although I'd be tempted to deserialize arr directly as an IEnumerable<LocationData>, which would save some code and effort of looping through the array. If you aren't going to use the parsed version separately, it's best to avoid it.

A few comments:

• The Nyquist frequency is half the sampling rate.
• You are working with regularly sampled data, so you want a digital filter, not an analog filter. This means you should not use analog=True in the call to butter, and you should use scipy.signal.freqz (not freqs) to generate the frequency response.
• One goal of those short utility functions is to allow you to leave all your frequencies expressed in Hz. You shouldn't have to convert to rad/sec. As long as you express your frequencies with consistent units, the scaling in the utility functions takes care of the normalization for you.

Here's my modified version of your script, followed by the plot that it generates.

import numpy as np
from scipy.signal import butter, lfilter, freqz
import matplotlib.pyplot as plt


def butter_lowpass(cutoff, fs, order=5):
    nyq = 0.5 * fs
    normal_cutoff = cutoff / nyq
    b, a = butter(order, normal_cutoff, btype='low', analog=False)
    return b, a

def butter_lowpass_filter(data, cutoff, fs, order=5):
    b, a = butter_lowpass(cutoff, fs, order=order)
    y = lfilter(b, a, data)
    return y


# Filter requirements.
order = 6
fs = 30.0       # sample rate, Hz
cutoff = 3.667  # desired cutoff frequency of the filter, Hz

# Get the filter coefficients so we can check its frequency response.
b, a = butter_lowpass(cutoff, fs, order)

# Plot the frequency response.
w, h = freqz(b, a, worN=8000)
plt.subplot(2, 1, 1)
plt.plot(0.5*fs*w/np.pi, np.abs(h), 'b')
plt.plot(cutoff, 0.5*np.sqrt(2), 'ko')
plt.axvline(cutoff, color='k')
plt.xlim(0, 0.5*fs)
plt.title("Lowpass Filter Frequency Response")
plt.xlabel('Frequency [Hz]')
plt.grid()


# Demonstrate the use of the filter.
# First make some data to be filtered.
T = 5.0         # seconds
n = int(T * fs) # total number of samples
t = np.linspace(0, T, n, endpoint=False)
# "Noisy" data.  We want to recover the 1.2 Hz signal from this.
data = np.sin(1.2*2*np.pi*t) + 1.5*np.cos(9*2*np.pi*t) + 0.5*np.sin(12.0*2*np.pi*t)

# Filter the data, and plot both the original and filtered signals.
y = butter_lowpass_filter(data, cutoff, fs, order)

plt.subplot(2, 1, 2)
plt.plot(t, data, 'b-', label='data')
plt.plot(t, y, 'g-', linewidth=2, label='filtered data')

Just to add to @ThijsW's answer, there is a significant speed advantage to the first method over the concatenation method:

big = 1e5;
tic;
x = rand(big,1);
toc

x = zeros(big,1);
tic;
for ii = 1:big
    x(ii) = rand;
end
toc

x = []; 
tic; 
for ii = 1:big
    x(end+1) = rand; 
end; 
toc 

x = []; 
tic; 
for ii = 1:big
    x = [x rand]; 
end; 
toc

   Elapsed time is 0.004611 seconds.
   Elapsed time is 0.016448 seconds.
   Elapsed time is 0.034107 seconds.
   Elapsed time is 12.341434 seconds.

I got these times running in 2012b however when I ran the same code on the same computer in matlab 2010a I get

Elapsed time is 0.003044 seconds.
Elapsed time is 0.009947 seconds.
Elapsed time is 12.013875 seconds.
Elapsed time is 12.165593 seconds.

So I guess the speed advantage only applies to more recent versions of Matlab

There are many ways to list all containers.

You can find using 3 Aliasesls, ps, list like this.

sudo docker container ls 
sudo docker container ps
sudo docker container list
sudo docker ps
sudo docker ps -a

You can also use give option[option].

Options -:

  -a, --all             Show all containers (default shows just running)
  -f, --filter filter   Filter output based on conditions provided
      --format string   Pretty-print containers using a Go template
  -n, --last int        Show last created containers (includes all states) (default -1)
  -l, --latest          Show the latest created container (includes all states)
      --no-trunc        Don't truncate output
  -q, --quiet           Only display numeric IDs
  -s, --size            Display total file sizes

You can use an option like this:

sudo docker ps //Showing only running containers
sudo docker ps -a //All container (running + stopped)
sudo docker pa -l // latest

Using .enumerate() works, but it does not provide the true index of the element; it only provides an Int beginning with 0 and incrementing by 1 for each successive element. This is usually irrelevant, but there is the potential for unexpected behavior when used with the ArraySlice type. Take the following code:

let a = ["a", "b", "c", "d", "e"]
a.indices //=> 0..<5

let aSlice = a[1..<4] //=> ArraySlice with ["b", "c", "d"]
aSlice.indices //=> 1..<4

var test = [Int: String]()
for (index, element) in aSlice.enumerate() {
    test[index] = element
}
test //=> [0: "b", 1: "c", 2: "d"] // indices presented as 0..<3, but they are actually 1..<4
test[0] == aSlice[0] // ERROR: out of bounds

It's a somewhat contrived example, and it's not a common issue in practice but still I think it's worth knowing this can happen.

The Syabru Nagios JMX plugin is meant to be used from Nagios, but doesn't require Nagios and is very convenient for command-line use:

~$ ./check_jmx -U service:jmx:rmi:///jndi/rmi://localhost:1099/JMXConnector --username myuser --password mypass -O java.lang:type=Memory -A HeapMemoryUsage -K used 
JMX OK - HeapMemoryUsage.used = 445012360 | 'HeapMemoryUsage used'=445012360;;;;

This one worked for me:

ServicePointManager.SecurityProtocol = SecurityProtocolType.Tls12;

I hope this will help you:

You can use iterative inorder traversal: http://en.wikipedia.org/wiki/Tree_traversal#Iterative_Traversal with a simple check for kth element after poping a node out of the stack.

No, there is no such type. But there are some choices:

• Dynamically generated queries (sp_executesql)
• Temporary tables
• Table-type variables (closest thing that there is to a list)
• Create an XML string and then convert it to a table with the XML functions (really awkward and roundabout, unless you have an XML to start with)

None of these are really elegant, but that's the best there is.

Without opening an IDE to check my brain works properly for syntax at this time of day...

If you simply want the date in a particular format you can use DateTime's .ToString(string format). There are a number of examples of standard and custom formatting strings if you follow that link.

So

DateTime _date = DateTime.Now;
var _dateString = _date.ToString("dd/MM/yyyy");

would give you the date as a string in the format you request.

Ctrl + F5 is better, because you don't need additional lines. And you can, in the end, hit enter and exit running mode.

But, when you start a program with F5 and put a break-point, you can debug your application and that gives you other advantages.

Try something like:

CREATE FUNCTION ColumnExists(@TableName varchar(100), @ColumnName varchar(100))
RETURNS varchar(1) AS
BEGIN
DECLARE @Result varchar(1);
IF EXISTS (SELECT * FROM INFORMATION_SCHEMA.Columns WHERE TABLE_NAME = @TableName AND COLUMN_NAME = @ColumnName)
BEGIN
    SET @Result = 'T'
END
ELSE
BEGIN
    SET @Result = 'F'
END
RETURN @Result;
END
GO

GRANT EXECUTE ON  [ColumnExists] TO [whoever]
GO

Then use it like this:

IF ColumnExists('xxx', 'yyyy') = 'F'
BEGIN
  ALTER TABLE xxx
  ADD yyyyy varChar(10) NOT NULL
END
GO

It should work on both SQL Server 2000 & SQL Server 2005. Not sure about SQL Server 2008, but don't see why not.

In my case, I noticed that the routing logic was kicking in if I modified the $location.hash(). The following trick worked..

$scope.scrollTo = function(id) {
    var old = $location.hash();
    $location.hash(id);
    $anchorScroll();
    //reset to old to keep any additional routing logic from kicking in
    $location.hash(old);
};

"Display or hide the matched elements."

This is much shorter in code than using show() and hide() methods.

This is similar to CommonsWare answer but with a minor tweak: android:gravity="top|start". Complete code example:

<EditText
    android:id="@+id/EditText02"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:lines="5"
    android:gravity="top|start"
    android:inputType="textMultiLine"
    android:scrollHorizontally="false" 
/>

The only solution I have found so far is to remove the view from its superview:

[view removeFromSuperview]

This looks like it removes all constraints affecting its layout and is ready to be added to a superview and have new constraints attached. However, it will incorrectly remove any subviews from the hierarchy as well, and get rid of [C7] incorrectly.

The .ToLowerCase version is not going to be faster - it involves an extra string allocation (which must later be collected), etc.

Personally, I'd use

string.Equals(val, "astringvalue",  StringComparison.OrdinalIgnoreCase)

this avoids all the issues of culture-sensitive strings, but as a consequence it avoids all the issues of culture-sensitive strings. Only you know whether that is OK in your context.

Using the string.Equals static method avoids any issues with val being null.

There are just two kinds of languages: the ones everybody complains about and the ones nobody uses.

Bjarne Stroustrup

I resolve this problem like this:

var util = require('util');

// Our circular object
var obj = {foo: {bar: null}, a:{a:{a:{a:{a:{a:{a:{hi: 'Yo!'}}}}}}}};
obj.foo.bar = obj;

// Generate almost valid JS object definition code (typeof string)
var str = util.inspect(b, {depth: null});

// Fix code to the valid state (in this example it is not required, but my object was huge and complex, and I needed this for my case)
str = str
    .replace(/<Buffer[ \w\.]+>/ig, '"buffer"')
    .replace(/\[Function]/ig, 'function(){}')
    .replace(/\[Circular]/ig, '"Circular"')
    .replace(/\{ \[Function: ([\w]+)]/ig, '{ $1: function $1 () {},')
    .replace(/\[Function: ([\w]+)]/ig, 'function $1(){}')
    .replace(/(\w+): ([\w :]+GMT\+[\w \(\)]+),/ig, '$1: new Date("$2"),')
    .replace(/(\S+): ,/ig, '$1: null,');

// Create function to eval stringifyed code
var foo = new Function('return ' + str + ';');

// And have fun
console.log(JSON.stringify(foo(), null, 4));

You might have done something like this:

>>> tuple = 45, 34  # You used `tuple` as a variable here
>>> tuple
(45, 34)
>>> l = [4, 5, 6]
>>> tuple(l)   # Will try to invoke the variable `tuple` rather than tuple type.

Traceback (most recent call last):
  File "<pyshell#10>", line 1, in <module>
    tuple(l)
TypeError: 'tuple' object is not callable
>>>
>>> del tuple  # You can delete the object tuple created earlier to make it work
>>> tuple(l)
(4, 5, 6)

Here's the problem... Since you have used a tuple variable to hold a tuple (45, 34) earlier... So, now tuple is an object of type tuple now...

It is no more a type and hence, it is no more Callable.

Never use any built-in types as your variable name... You do have any other name to use. Use any arbitrary name for your variable instead...

For what it's worth, I've run into this on what was previously working code. I had added SELECT statements in a trigger for debug testing and forgot to remove them. Entity Framework / MVC doesnt play nice when other stuff is output to the "grid". Make sure to check for any rogue queries and remove them.

tl;dr

LocalDate::plusMonths

Example:

LocalDate.now( )
         .plusMonths( 1 );

Better to specify time zone.

LocalDate.now( ZoneId.of( "America/Montreal" )
         .plusMonths( 1 );

java.time

The java.time framework is built into Java 8 and later. These classes supplant the old troublesome date-time classes such as java.util.Date, .Calendar, & java.text.SimpleDateFormat. The Joda-Time team also advises migration to java.time.

To learn more, see the Oracle Tutorial. And search Stack Overflow for many examples and explanations.

Much of the java.time functionality is back-ported to Java 6 & 7 in ThreeTen-Backport and further adapted to Android in ThreeTenABP.

Date-only

If you want the date-only, use the LocalDate class.

ZoneId z = ZoneId.of( "America/Montreal" );
 LocalDate today = LocalDate.now( z );

today.toString(): 2017-01-23

Add a month.

LocalDate oneMonthLater = today.plusMonths( 1 );

oneMonthLater.toString(): 2017-02-23

Date-time

Perhaps you want a time-of-day along with the date.

First get the current moment in UTC with a resolution of nanoseconds.

Instant instant = Instant.now();

Adding a month means determining dates. And determining dates means applying a time zone. For any given moment, the date varies around the world with a new day dawning earlier to the east. So adjust that Instant into a time zone.

ZoneId zoneId = ZoneId.of( "America/Montreal" );
ZonedDateTime zdt = ZonedDateTime.ofInstant( instant , zoneId );

Now add your month. Let java.time handle Leap month, and the fact that months vary in length.

ZonedDateTime zdtMonthLater = zdt.plusMonths( 1 );

You might want to adjust the time-of-day to the first moment of the day when making this kind of calculation. That first moment is not always 00:00:00.0 so let java.time determine the time-of-day.

ZonedDateTime zdtMonthLaterStartOfDay = zdtMonthLater.toLocalDate().atStartOfDay( zoneId );

About java.time

The java.time framework is built into Java 8 and later. These classes supplant the troublesome old legacy date-time classes such as java.util.Date, Calendar, & SimpleDateFormat.

The Joda-Time project, now in maintenance mode, advises migration to the java.time classes.

To learn more, see the Oracle Tutorial. And search Stack Overflow for many examples and explanations. Specification is JSR 310.

Where to obtain the java.time classes?

• Java SE 8, Java SE 9, and later
  • Built-in.
  • Part of the standard Java API with a bundled implementation.
  • Java 9 adds some minor features and fixes.
• Java SE 6 and Java SE 7
  • Much of the java.time functionality is back-ported to Java 6 & 7 in ThreeTen-Backport.
• Android
  • The ThreeTenABP project adapts ThreeTen-Backport (mentioned above) for Android specifically.
  • See How to use ThreeTenABP….

The ThreeTen-Extra project extends java.time with additional classes. This project is a proving ground for possible future additions to java.time. You may find some useful classes here such as Interval, YearWeek, YearQuarter, and more.

Joda-Time

Update: The Joda-Time project is now in maintenance mode. Its team advises migration to the java.time classes. I am leaving this section intact for posterity.

The Joda-Time library offers a method to add months in a smart way.

DateTimeZone timeZone = DateTimeZone.forID( "Europe/Paris" );
DateTime now = DateTime.now( timeZone );
DateTime nextMonth = now.plusMonths( 1 );

You might want to focus on the day by adjust the time-of-day to the first moment of the day.

DateTime nextMonth = now.plusMonths( 1 ).withTimeAtStartOfDay();

What even is ‘children’?

The React docs say that you can use props.children on components that represent ‘generic boxes’ and that don’t know their children ahead of time. For me, that didn’t really clear things up. I’m sure for some, that definition makes perfect sense but it didn’t for me.

My simple explanation of what this.props.children does is that it is used to display whatever you include between the opening and closing tags when invoking a component.

A simple example:

Here’s an example of a stateless function that is used to create a component. Again, since this is a function, there is no this keyword so just use props.children

const Picture = (props) => {
  return (
    <div>
      <img src={props.src}/>
      {props.children}
    </div>
  )
}

This component contains an <img> that is receiving some props and then it is displaying {props.children}.

Whenever this component is invoked {props.children} will also be displayed and this is just a reference to what is between the opening and closing tags of the component.

//App.js
render () {
  return (
    <div className='container'>
      <Picture key={picture.id} src={picture.src}>
          //what is placed here is passed as props.children  
      </Picture>
    </div>
  )
}

Instead of invoking the component with a self-closing tag <Picture /> if you invoke it will full opening and closing tags <Picture> </Picture> you can then place more code between it.

This de-couples the <Picture> component from its content and makes it more reusable.

Reference: A quick intro to React’s props.children

I had to rm -rf ./vendor then run bundle install again.

The reason your code doesn't work is because the count function is asynchronous, it doesn't synchronously return a value.

Here's an example of usage:

userModel.count({}, function( err, count){
    console.log( "Number of users:", count );
})

You can use reject method of Underscore, below will return a new array which won't have array with particular match

arr = _.reject(arr, function(objArr){ return objArr.id == 3; });

You can use mplayer.

mencoder -nocache -rtsp-stream-over-tcp rtsp://192.168.XXX.XXX/test.sdp -oac copy -ovc copy -o test.avi

The "copy" codec is just a dumb copy of the stream. Mencoder adds a header and stuff you probably want.

In the mplayer source file "stream/stream_rtsp.c" is a prebuffer_size setting of 640k and no option to change the size other then recompile. The result is that writing the stream is always delayed, which can be annoying for things like cameras, but besides this, you get an output file, and can play it back most places without a problem.

you should run standlone.bat or .sh with -c standalone-full.xml switch may be work.

I'd say, it depends on your situation. For example, I work in local government, and we have lots of images like mugshots, etc. We don't have a high number of users, but we need to have good security and auditing around the data. The database is a better solution for us since it makes this easier and we aren't going to run into scaling problems.

I resolved this issue on centos5.4 by running the following command to install setuptools

yum install python-setuptools

I hope that helps.

All tables within the bootstrap stretch according to their container, which you can easily do by placing your table inside a .span* grid element of your choice. If you wish to remove this property you can create your own table class and simply add it to the table you want to expand with the content within:

.table-nonfluid {
   width: auto !important;
}

You can add this class inside your own stylesheet and simply add it to the container of your table like so:

<table class="table table-nonfluid"> ... </table>

This way your change won't affect the bootstrap stylesheet itself (you might want to have a fluid table somewhere else in your document).

Detect most browsers with this:

var getBrowser = function(){
  var navigatorObj = navigator.appName,
      userAgentObj = navigator.userAgent,
      matchVersion;
  var match = userAgentObj.match(/(opera|chrome|safari|firefox|msie|trident)\/?\s*(\.?\d+(\.\d+)*)/i);
  if( match && (matchVersion = userAgentObj.match(/version\/([\.\d]+)/i)) !== null) match[2] = matchVersion[1];
  //mobile
  if (navigator.userAgent.match(/iPhone|Android|webOS|iPad/i)) {
    return match ? [match[1], match[2], mobile] : [navigatorObj, navigator.appVersion, mobile];
  }
  // web browser
  return match ? [match[1], match[2]] : [navigatorObj, navigator.appVersion, '-?'];
};

String[] args means an array of sequence of characters (Strings) that are passed to the "main" function. This happens when a program is executed.

Example when you execute a Java program via the command line:

java MyProgram This is just a test

Therefore, the array will store: ["This", "is", "just", "a", "test"]

Use these few simple commands:

mysqldump -u username -p -v olddatabase > olddbdump.sql
mysqladmin -u username -p create newdatabase
mysql -u username -p newdatabase < olddbdump.sql

Or to reduce I/O use the following as suggested by @Pablo Marin-Garcia:

mysqladmin -u username -p create newdatabase
mysqldump -u username -v olddatabase -p | mysql -u username -p -D newdatabase

If you have multiple sections, here's how to get the last row in the last section (Swift 3):

func tableView(_ tableView: UITableView, willDisplay cell: UITableViewCell, forRowAt indexPath: IndexPath) {
    if let visibleRows = tableView.indexPathsForVisibleRows, let lastRow = visibleRows.last?.row, let lastSection = visibleRows.map({$0.section}).last {
        if indexPath.row == lastRow && indexPath.section == lastSection {
            // Finished loading visible rows

        }
    }
}

Basically http.antMatcher() tells Spring to only configure HttpSecurity if the path matches this pattern.

For people in the future seeing this, postgres is in the /usr/lib/postgresql/10/bin on my Ubuntu server.

I added it to the PATH in my .bashrc file, and add this line at the end

PATH=$PATH:/usr/lib/postgresql/10/bin

then on the command line

$> source ./.bashrc

I refreshed my bash environment. Now I can use postgres -D /wherever from any directory

An example with for loop (I prefer List Comprehensions).

a, b = '[br]', '<br />'
for i, v in enumerate(words):
    if a in v:
        words[i] = v.replace(a, b)
print(words)
# ['how', 'much', 'is<br/>', 'the', 'fish<br/>', 'no', 'really']

From the Sonatype doc:

The answer to this question depends on your own perspective. The great majority of Maven users are going to call Maven a “build tool”: a tool used to build deployable artifacts from source code. Build engineers and project managers might refer to Maven as something more comprehensive: a project management tool. What is the difference? A build tool such as Ant is focused solely on preprocessing, compilation, packaging, testing, and distribution. A project management tool such as Maven provides a superset of features found in a build tool. In addition to providing build capabilities, Maven can also run reports, generate a web site, and facilitate communication among members of a working team.

I'd strongly recommend looking at the Sonatype doc and spending some time looking at the available plugins to understand the power of Maven.

Very briefly, it operates at a higher conceptual level than (say) Ant. With Ant, you'd specify the set of files and resources that you want to build, then specify how you want them jarred together, and specify the order that should occur in (clean/compile/jar). With Maven this is all implicit. Maven expects to find your files in particular places, and will work automatically with that. Consequently setting up a project with Maven can be a lot simpler, but you have to play by Maven's rules!

You can do something like this to read your nodes.

Also you can find some explanation in this page http://www.compoc.com/tuts/

<script type="text/javascript">
        var markers = null;
        $(document).ready(function () {
            $.get("File.xml", {}, function (xml){
              $('marker',xml).each(function(i){
                 markers = $(this);
              });
            });
        });
</script>

You can use jOOR for that.

class Foo {
    private final String value = "ABC";
}
class Bar {
    private final Foo foo = new Foo();
    public String value() {
        return org.joor.Reflect
            .on(this.foo)
            .field("value")
            .get();
    }
}
class BarTest {
    @Test
    void accessPrivateField() {
        Assertions.assertEquals(new Bar().value(), "ABC");
    }
}

For the list example, use a comprehension:

>>> l = ['ll', 'xx', 'll']
>>> print [n for (n, e) in enumerate(l) if e == 'll']
[0, 2]

Similarly for strings:

>>> text = "Allowed Hello Hollow"
>>> print [n for n in xrange(len(text)) if text.find('ll', n) == n]
[1, 10, 16]

this will list adjacent runs of "ll', which may or may not be what you want:

>>> text = 'Alllowed Hello Holllow'
>>> print [n for n in xrange(len(text)) if text.find('ll', n) == n]
[1, 2, 11, 17, 18]

There is not only 1 %SystemRoot%\System32 on Windows x64. There are 2 such directories.

The real %SystemRoot%\System32 directory is for 64-bit applications. This directory contains a 64-bit cmd.exe.

But there is also %SystemRoot%\SysWOW64 for 32-bit applications. This directory is used if a 32-bit application accesses %SystemRoot%\System32. It contains a 32-bit cmd.exe.

32-bit applications can access %SystemRoot%\System32 for 64-bit applications by using the alias %SystemRoot%\Sysnative in path.

For more details see the Microsoft documentation about File System Redirector.

So the subdirectory run was created either in %SystemRoot%\System32 for 64-bit applications and 32-bit cmd is run for which this directory does not exist because there is no subdirectory run in %SystemRoot%\SysWOW64 which is %SystemRoot%\System32 for 32-bit cmd.exe or the subdirectory run was created in %SystemRoot%\System32 for 32-bit applications and 64-bit cmd is run for which this directory does not exist because there is no subdirectory run in %SystemRoot%\System32 as this subdirectory exists only in %SystemRoot%\SysWOW64.

The following code could be used at top of the batch file in case of subdirectory run is in %SystemRoot%\System32 for 64-bit applications:

@echo off
set "SystemPath=%SystemRoot%\System32"
if not "%ProgramFiles(x86)%" == "" if exist %SystemRoot%\Sysnative\* set "SystemPath=%SystemRoot%\Sysnative"

Every console application in System32\run directory must be executed with %SystemPath% in the batch file, for example %SystemPath%\run\YourApp.exe.

How it works?

There is no environment variable ProgramFiles(x86) on Windows x86 and therefore there is really only one %SystemRoot%\System32 as defined at top.

But there is defined the environment variable ProgramFiles(x86) with a value on Windows x64. So it is additionally checked on Windows x64 if there are files in %SystemRoot%\Sysnative. In this case the batch file is processed currently by 32-bit cmd.exe and only in this case %SystemRoot%\Sysnative needs to be used at all. Otherwise %SystemRoot%\System32 can be used also on Windows x64 as when the batch file is processed by 64-bit cmd.exe, this is the directory containing the 64-bit console applications (and the subdirectory run).

Note: %SystemRoot%\Sysnative is not a directory! It is not possible to cd to %SystemRoot%\Sysnative or use if exist %SystemRoot%\Sysnative or if exist %SystemRoot%\Sysnative\. It is a special alias existing only for 32-bit executables and therefore it is necessary to check if one or more files exist on using this path by using if exist %SystemRoot%\Sysnative\cmd.exe or more general if exist %SystemRoot%\Sysnative\*.

While pure JavaScript is sufficient here, I still prefer the jQuery approach. After all, the ask was to get the hostname using jQuery.

var hostName = $(location).attr('hostname');      // www.example.com

Use HttpClientBuilder to build the HttpClient instead of using DefaultHttpClient

ex:

MinimalHttpClient httpclient = new HttpClientBuilder().build();

 // Prepare a request object
 HttpGet httpget = new HttpGet("http://www.apache.org/");

The JVM doesn't know anything about off-heap memory. Ehcache implements an on-disk cache as well as an in-memory cache.

I had similar problem, I had a list and I have to build a SQL script based on template (that contained @INPUT@ as element to replace):

for i in LIST

done

As @Ming mentioned:

pip install -r file.txt

Here's a simple line to force update all dependencies:

while read -r package; do pip install --upgrade --force-reinstall $package;done < pipfreeze.txt

This should work

gsub('\u009c','','\u009cYes yes for ever for ever the boys ')
"Yes yes for ever for ever the boys "

Here 009c is the hexadecimal number of unicode. You must always specify 4 hexadecimal digits. If you have many , one solution is to separate them by a pipe:

gsub('\u009c|\u00F0','','\u009cYes yes \u00F0for ever for ever the boys and the girls')

"Yes yes for ever for ever the boys and the girls"

use this URL : "https://twitter.com/(userName)/profile_image?size=original"

If you are using TWitter SDK you can get the user name when logged in, with TWTRAPIClient, using TWTRAuthSession.

This is the code snipe for iOS:

if let twitterId = session.userID{
   let twitterClient = TWTRAPIClient(userID: twitterId)
   twitterClient.loadUser(withID: twitterId) {(user, error) in
       if let userName = user?.screenName{
          let url = "https://twitter.com/\(userName)/profile_image?size=original")
       }
   }
}

Use the textchange event via customized jQuery shim for cross-browser input compatibility. http://benalpert.com/2013/06/18/a-near-perfect-oninput-shim-for-ie-8-and-9.html (most recently forked github: https://github.com/pandell/jquery-splendid-textchange/blob/master/jquery.splendid.textchange.js)

This handles all input tags including <textarea>content</textarea>, which does not always work with change keyup etc. (!) Only jQuery on("input propertychange") handles <textarea> tags consistently, and the above is a shim for all browsers that don't understand input event.

<!DOCTYPE html>
<html>
<head>
<script class="jsbin" src="http://ajax.googleapis.com/ajax/libs/jquery/1/jquery.min.js"></script>
<script src="https://raw.githubusercontent.com/pandell/jquery-splendid-textchange/master/jquery.splendid.textchange.js"></script>
<meta charset=utf-8 />
<title>splendid textchange test</title>

<script> // this is all you have to do. using splendid.textchange.js

$('textarea').on("textchange",function(){ 
  yourFunctionHere($(this).val());    });  

</script>
</head>
<body>
  <textarea style="height:3em;width:90%"></textarea>
</body>
</html>

JS Bin test

This also handles paste, delete, and doesn't duplicate effort on keyup.

If not using a shim, use jQuery on("input propertychange") events.

// works with most recent browsers (use this if not using src="...splendid.textchange.js")

$('textarea').on("input propertychange",function(){ 
  yourFunctionHere($(this).val());    
});  

For unsigned numbers you can use these classes from Guava library:

• UnsignedInteger
• UnsignedLong

They support various operations:

• plus
• minus
• times
• mod
• dividedBy

The thing that seems missing at the moment are byte shift operators. If you need those you can use BigInteger from Java.

$location won't help you with external URLs, use the $window service instead:

$window.location.href = 'http://www.google.com';

Note that you could use the window object, but it is bad practice since $window is easily mockable whereas window is not.

Arrays in JavaScript don't use strings as keys. You will probably find that the value is there, but the key is an integer.

If you make Dict into an object, this will work:

var dict = {};
var addPair = function (myKey, myValue) {
    dict[myKey] = myValue;
};
var giveValue = function (myKey) {
    return dict[myKey];
};

The myKey variable is already a string, so you don't need more quotes.

Just in case someone wants only update project's snapshot dependencies and doesn't want to install artifact:

mvn dependency:resolve -U

Don't forget to reimport dependencies in your IDE. In IDEA you need to right click on pom file and choose Maven -> Reimport

You should consider using a button for this. Links generally should be use for linking. Buttons can be used for other functionality you wish to add. Neals solution works, but its a workaround.

If you use a <button> instead of a <a>, your original code should work as expected.

Not really what you're looking for, but it may be useful to you. Face Detection/Computer Vision algorithms in MATLAB.

It's a pretty useful functionality, for example here is a Node.js code snippet to test the set up of a 3 second timing function.

const waitTime = 3000;
console.log(`setting a ${waitTime/1000} second delay`);

Explanation

1. Declare wait time as 3000
2. Using the backtick you can embed the result of the calculation of 'wait time' divided by 1000 in the same line with your chosen text.
3. Further calling a timer function using the 'waitTime' constant will result in a 3 second delay, as calculated in the console.log argument.

The difference between a recursive and non-recursive mutex has to do with ownership. In the case of a recursive mutex, the kernel has to keep track of the thread who actually obtained the mutex the first time around so that it can detect the difference between recursion vs. a different thread that should block instead. As another answer pointed out, there is a question of the additional overhead of this both in terms of memory to store this context and also the cycles required for maintaining it.

However, there are other considerations at play here too.

Because the recursive mutex has a sense of ownership, the thread that grabs the mutex must be the same thread that releases the mutex. In the case of non-recursive mutexes, there is no sense of ownership and any thread can usually release the mutex no matter which thread originally took the mutex. In many cases, this type of "mutex" is really more of a semaphore action, where you are not necessarily using the mutex as an exclusion device but use it as synchronization or signaling device between two or more threads.

Another property that comes with a sense of ownership in a mutex is the ability to support priority inheritance. Because the kernel can track the thread owning the mutex and also the identity of all the blocker(s), in a priority threaded system it becomes possible to escalate the priority of the thread that currently owns the mutex to the priority of the highest priority thread that is currently blocking on the mutex. This inheritance prevents the problem of priority inversion that can occur in such cases. (Note that not all systems support priority inheritance on such mutexes, but it is another feature that becomes possible via the notion of ownership).

If you refer to classic VxWorks RTOS kernel, they define three mechanisms:

• mutex - supports recursion, and optionally priority inheritance. This mechanism is commonly used to protect critical sections of data in a coherent manner.
• binary semaphore - no recursion, no inheritance, simple exclusion, taker and giver does not have to be same thread, broadcast release available. This mechanism can be used to protect critical sections, but is also particularly useful for coherent signalling or synchronization between threads.
• counting semaphore - no recursion or inheritance, acts as a coherent resource counter from any desired initial count, threads only block where net count against the resource is zero.

Again, this varies somewhat by platform - especially what they call these things, but this should be representative of the concepts and various mechanisms at play.

File mode, write and binary. Since you are writing a .jpg file, it looks fine.

But if you supposed to read that jpg file you need to use 'rb'

More info

On Windows, 'b' appended to the mode opens the file in binary mode, so there are also modes like 'rb', 'wb', and 'r+b'. Python on Windows makes a distinction between text and binary files; the end-of-line characters in text files are automatically altered slightly when data is read or written. This behind-the-scenes modification to file data is fine for ASCII text files, but it’ll corrupt binary data like that in JPEG or EXE files.

you can either use

echo '<a href="'.$link_address.'">Link</a>';

or

echo "<a href=\"$link_address\">Link</a>';

if you use double quotes you can insert the variable into the string and it will be parsed.

To change which upstream remote is "wired" to your branch, use the git branch command with the upstream configuration flag.

Ensure the remote exists first:

git remote -vv

Set the preferred remote for the current (checked out) branch:

git branch --set-upstream-to <remote-name>

Validate the branch is setup with the correct upstream remote:

git branch -vv

Here is complete example using NLog

using NLog;
using System;
using System.Windows;

    /// <summary>
    /// Interaction logic for App.xaml
    /// </summary>
    public partial class App : Application

        public App()
        {
            var currentDomain = AppDomain.CurrentDomain;
            currentDomain.UnhandledException += CurrentDomain_UnhandledException;
        }

        private void CurrentDomain_UnhandledException(object sender, UnhandledExceptionEventArgs e)
        {
            var ex = (Exception)e.ExceptionObject;
            logger.Error("UnhandledException caught : " + ex.Message);
            logger.Error("UnhandledException StackTrace : " + ex.StackTrace);
            logger.Fatal("Runtime terminating: {0}", e.IsTerminating);
        }        
    }

Getting this error, I changed the

c/C++ > Code Generation > Runtime Library to Multi-threaded library (DLL) /MD

for both code project and associated Google Test project. This solved the issue.

Note: all components of the project must have the same definition in c/C++ > Code Generation > Runtime Library. Either DLL or not DLL, but identical.

From command prompt Run as Administrator. Example below is to print a list of Services running on your PC run the command below:

net start > c:\netstart.txt

You should see a copy of the text file you just exported with a listing all the PC services running at the root of your C:\ drive.

I got the same issue while running the skiprows while reading the csv file. I was doning skip_rows=1 this will not work

Simple example gives an idea how to use skiprows while reading csv file.

import pandas as pd

#skiprows=1 will skip first line and try to read from second line
df = pd.read_csv('my_csv_file.csv', skiprows=1)  ## pandas as pd

#print the data frame
df

@RequestMapping(
         value="person", 
         method=RequestMethod.POST,
         consumes="application/json",
         produces="application/json")
@ResponseBody
public List<String> savePerson(@RequestBody Person[] personArray) {
    List<String> response = new ArrayList<String>();
    for (Person person: personArray) {
        personService.save(person);
        response.add("Saved person: " + person.toString());
    }
    return response;
}

We can use Array as shown above.

If the link should only change the location if the function run is successful, then do onclick="return runMyFunction();" and in the function you would return true or false.

If you just want to run the function, and then let the anchor tag do its job, simply remove the return false statement.

As a side note, you should probably use an event handler instead, as inline JS isn't a very optimal way of doing things.

Renders a view and sends the rendered HTML string to the client.

res.render('index');

Or

res.render('index', function(err, html) {
  if(err) {...}
  res.send(html);
});

DOCS HERE: https://expressjs.com/en/api.html#res.render

There is no such feature in markdown, however you can always use HTML inside markdown:

<a href="http://example.com/" target="_blank">example</a>

In last versions, it is easier. Just put a ml-auto class in the ul like so:

<ul class="nav navbar-nav ml-auto">

This can happen with a 401 http response if using NSURLConnection.

See NSURLConnection returning error instead of response for 401

The simpliest solution (in case you are using fastcgi+nignx) is what itgorilla commented:

Thank you for this great question. My fastcgi was not passing the REMOTE_ADDR meta key. I added the line below in the nginx.conf and fixed the problem: fastcgi_param REMOTE_ADDR $remote_addr; – itgorilla

Ps: I added this answer just to make his solution more visible.

You can use Arrays.sort() method. Here's the example,

import java.util.Arrays;

public class Test 
{
    public static void main(String[] args) 
    {
        String arrString[] = { "peter", "taylor", "brooke", "frederick", "cameron" };
        orderedGuests(arrString);
    }

    public static void orderedGuests(String[] hotel)
    {
        Arrays.sort(hotel);
        System.out.println(Arrays.toString(hotel));
    }
}

Output

[brooke, cameron, frederick, peter, taylor]

Only one change was needed to fix the problem:

Go to Start -> Control Panel -> System -> Advanced(tab) -> Environment Variables -> System Variables

set ANDROID_HOME to C:\Program Files (x86)\Android\android-sdk

You can use either the language construct isset, or the function array_key_exists.

isset should be a bit faster (as it's not a function), but will return false if the element exists and has the value NULL.

For example, considering this array :

$a = array(
    123 => 'glop', 
    456 => null, 
);

And those three tests, relying on isset :

var_dump(isset($a[123]));
var_dump(isset($a[456]));
var_dump(isset($a[789]));

The first one will get you (the element exists, and is not null) :

boolean true

While the second one will get you (the element exists, but is null) :

boolean false

And the last one will get you (the element doesn't exist) :

boolean false

On the other hand, using array_key_exists like this :

var_dump(array_key_exists(123, $a));
var_dump(array_key_exists(456, $a));
var_dump(array_key_exists(789, $a));

You'd get those outputs :

boolean true
boolean true
boolean false

Because, in the two first cases, the element exists -- even if it's null in the second case. And, of course, in the third case, it doesn't exist.

For situations such as yours, I generally use isset, considering I'm never in the second case... But choosing which one to use is now up to you ;-)

For instance, your code could become something like this :

if (!isset(self::$instances[$instanceKey])) {
    $instances[$instanceKey] = $theInstance;
}

The scroll speed CAN be changed, adjusted, reversed, all of the above - via javascript (or a js library such as jQuery).

WHY would you want to do this? Parallax is just one of the reasons. I have no idea why anyone would argue against doing so -- the same negative arguments can be made against hiding DIVs, sliding elements up/down, etc. Websites are always a combination of technical functionality and UX design -- a good designer can use almost any technical capability to improve UX. That is what makes him/her good.

Toni Almeida of Portugal created a brilliant demo, reproduced below:

jsFiddle Demo

HTML:

<div id="myDiv">
    Use the mouse wheel (not the scroll bar) to scroll this DIV. You will see that the scroll eventually slows down, and then stops. <span class="boldit">Use the mouse wheel (not the scroll bar) to scroll this DIV. You will see that the scroll eventually slows down, and then stops. </span>
</div>

javascript/jQuery:

  function wheel(event) {
      var delta = 0;
      if (event.wheelDelta) {(delta = event.wheelDelta / 120);}
      else if (event.detail) {(delta = -event.detail / 3);}

      handle(delta);
      if (event.preventDefault) {(event.preventDefault());}
      event.returnValue = false;
  }

  function handle(delta) {
      var time = 1000;
      var distance = 300;

      $('html, body').stop().animate({
          scrollTop: $(window).scrollTop() - (distance * delta)
      }, time );
  }

  if (window.addEventListener) {window.addEventListener('DOMMouseScroll', wheel, false);}
    window.onmousewheel = document.onmousewheel = wheel;

Change CI index.php file to:

if ($_SERVER['SERVER_NAME'] == 'local_server_name') {
    define('ENVIRONMENT', 'development');
} else {
    define('ENVIRONMENT', 'production');
}

if (defined('ENVIRONMENT')){
    switch (ENVIRONMENT){
        case 'development':
            error_reporting(E_ALL);
        break;

        case 'testing':
        case 'production':
            error_reporting(0);
        break;

        default:
            exit('The application environment is not set correctly.');
    }
}

IF PHP errors are off, but any MySQL errors are still going to show, turn these off in the /config/database.php file. Set the db_debug option to false:

$db['default']['db_debug'] = FALSE; 

Also, you can use active_group as development and production to match the environment https://www.codeigniter.com/user_guide/database/configuration.html

$active_group = 'development';


$db['development']['hostname'] = 'localhost';
$db['development']['username'] = '---';
$db['development']['password'] = '---';
$db['development']['database'] = '---';
$db['development']['dbdriver'] = 'mysql';
$db['development']['dbprefix'] = '';
$db['development']['pconnect'] = TRUE;

$db['development']['db_debug'] = TRUE;

$db['development']['cache_on'] = FALSE;
$db['development']['cachedir'] = '';
$db['development']['char_set'] = 'utf8';
$db['development']['dbcollat'] = 'utf8_general_ci';
$db['development']['swap_pre'] = '';
$db['development']['autoinit'] = TRUE;
$db['development']['stricton'] = FALSE;



$db['production']['hostname'] = 'localhost';
$db['production']['username'] = '---';
$db['production']['password'] = '---';
$db['production']['database'] = '---';
$db['production']['dbdriver'] = 'mysql';
$db['production']['dbprefix'] = '';
$db['production']['pconnect'] = TRUE;

$db['production']['db_debug'] = FALSE;

$db['production']['cache_on'] = FALSE;
$db['production']['cachedir'] = '';
$db['production']['char_set'] = 'utf8';
$db['production']['dbcollat'] = 'utf8_general_ci';
$db['production']['swap_pre'] = '';
$db['production']['autoinit'] = TRUE;
$db['production']['stricton'] = FALSE;

To make the render engine accept html instead of jade you can follow the following steps;

Install consolidate and swig to your directory.

 npm install consolidate
 npm install swig

add following lines to your app.js file

var cons = require('consolidate');

// view engine setup
app.engine('html', cons.swig)
app.set('views', path.join(__dirname, 'views'));
app.set('view engine', 'html');

add your view templates as .html inside “views” folder. Restart you node server and start the app in the browser.

This should work

There are a couple ways to do this.

First, instead of going into openssl command prompt mode, just enter everything on one command line from the Windows prompt:

E:\> openssl x509 -pubkey -noout -in cert.pem  > pubkey.pem

If for some reason, you have to use the openssl command prompt, just enter everything up to the ">". Then OpenSSL will print out the public key info to the screen. You can then copy this and paste it into a file called pubkey.pem.

openssl> x509 -pubkey -noout -in cert.pem

Output will look something like this:

Had similar problem. Added in build.gradle and it worked for me.

 compileOptions {
        sourceCompatibility JavaVersion.VERSION_1_8
        targetCompatibility JavaVersion.VERSION_1_8
    }

I also could not launch scripts, after heavy searching nothing helped. No -ExecutionPolicy, no commands, no files and no difference between "" and ''.

I simply put the command I ran in powershell in the argument tab: ./scripts.ps1 parameter1 11 parameter2 xx and so on. Now the scheduler works. Program: Powershell.exe Start in: C:/location/of/script/

Since you ask for the easiest way, I suggest using vagrant-scp. It adds a scp command to vagrant, so you can copy files to your VM like you would normally do with scp.

Install via:

vagrant plugin install vagrant-scp

Use it like so:

vagrant scp <some_local_file_or_dir> [vm_name]:<somewhere_on_the_vm>

First step is to load your xml string into an XmlDocument, using powershell's unique ability to cast strings to [xml]

$doc = [xml]@'
<xml>
    <Section name="BackendStatus">
        <BEName BE="crust" Status="1" />
        <BEName BE="pizza" Status="1" />
        <BEName BE="pie" Status="1" />
        <BEName BE="bread" Status="1" />
        <BEName BE="Kulcha" Status="1" />
        <BEName BE="kulfi" Status="1" />
        <BEName BE="cheese" Status="1" />
    </Section>
</xml>
'@

Powershell makes it really easy to parse xml with the dot notation. This statement will produce a sequence of XmlElements for your BEName elements:

$doc.xml.Section.BEName

Then you can pipe these objects into the where-object cmdlet to filter down the results. You can use ? as a shortcut for where

$doc.xml.Section.BEName | ? { $_.Status -eq 1 }

The expression inside the braces will be evaluated for each XmlElement in the pipeline, and only those that have a Status of 1 will be returned. The $_ operator refers to the current object in the pipeline (an XmlElement).

If you need to do something for every object in your pipeline, you can pipe the objects into the foreach-object cmdlet, which executes a block for every object in the pipeline. % is a shortcut for foreach:

$doc.xml.Section.BEName | ? { $_.Status -eq 1 } | % { $_.BE + " is delicious" }

Powershell is great at this stuff. It's really easy to assemble pipelines of objects, filter pipelines, and do operations on each object in the pipeline.

For those of us who have a github.com account, but only get a nasty error message when we type "git" into the command-line, here's how to do it all in your browser :)

1. Same as Tim and Farhan wrote: Fork your own copy of the project:
2. After a few seconds, you'll be redirected to your own forked copy of the project:
3. Navigate to the file(s) you need to change and click "Edit this file" in the toolbar:
4. After editing, write a few words describing the changes and then "Commit changes", just as well to the master branch (since this is only your own copy and not the "main" project).
5. Repeat steps 3 and 4 for all files you need to edit, and then go back to the root of your copy of the project. There, click the green "Compare, review..." button:
6. Finally, click "Create pull request" ..and then "Create pull request" again after you've double-checked your request's heading and description:

I also faced this issue. My Operating system is Ubuntu 18.04 and my PHP version is PHP 7.2.

Here's how I solved it:

Install Simplexml on your Ubuntu Server:

Restart Apache Server

sudo systemctl restart apache2

That's all.

I hope this helps

Wrapping components with braces if no default exports:

import {MyNavbar} from './comp/my-navbar.jsx';

or import multiple components from single module file

import {MyNavbar1, MyNavbar2} from './module';

If none of the above work, I also have a different approach, as it happened to me in a real scenario.

More specifically using auto-generated Ruby files from Thrift.

In my situation, I had a Module with several classes, so the order is important in this case:

Class A makes use of Class B in the same module. However, Class B was declared after Class A.

Simply making Class B to be declared before Class A solved the issue to me.

You didn't specify how the order is determined, but this will give you a rank value in MySQL:

SELECT t.*,
       @rownum := @rownum +1 AS rank
  FROM TBL_FOO t
  JOIN (SELECT @rownum := 0) r
 WHERE t.name = 'sarmen'

Then you can pick out what rows you want, based on the rank value.

OS=GNU/Linux Debian
Httpd=Apache/2.4.10

Change in /etc/apache2/apache2.conf

<Directory /var/www/html>
     Order Allow,Deny
     Allow from all
     AllowOverride all
     Header set Access-Control-Allow-Origin "*"
</Directory>

Add/activate module

 a2enmod headers 

Restart service

It's not possible anymore on devices running iOS 7.0 or later, thus unavailable to get MAC address in Swift.

As Apple stated:

In iOS 7 and later, if you ask for the MAC address of an iOS device, the system returns the value 02:00:00:00:00:00. If you need to identify the device, use the identifierForVendor property of UIDevice instead. (Apps that need an identifier for their own advertising purposes should consider using the advertisingIdentifier property of ASIdentifierManager instead.)

I am using rails 4.0 and ran into the same problem

Here is my solution that passed test

add to Gemfile

gem 'bootstrap-sass'

run

bundle install

then add to app/assets/javascripts/application.js

//= require bootstrap

Then the dropdown should work

By the way, Chris's solution also work for me.

But I think it is less conform to the asset pipeline idea

UPDATE for v1.1:

Rather than giving q="search_string" give it q="hashtag" in URL encoded form to return results with HASHTAG ONLY. So your query would become:

    GET https://api.twitter.com/1.1/search/tweets.json?q=%23freebandnames

%23 is URL encoded form of #. Try the link out in your browser and it should work.

You can optimize the query by adding since_id and max_id parameters detailed here. Hope this helps !

Note: Search API is now a OAUTH authenticated call, so please include your access_tokens to the above call

Updated

You can specify the interpretation order of the axes using the order parameter:

np.reshape(arr, (2, -1), order='F')

The standard ConfigParser normally requires access via config['section_name']['key'], which is no fun. A little modification can deliver attribute access:

class AttrDict(dict):
    def __init__(self, *args, **kwargs):
        super(AttrDict, self).__init__(*args, **kwargs)
        self.__dict__ = self

AttrDict is a class derived from dict which allows access via both dictionary keys and attribute access: that means a.x is a['x']

We can use this class in ConfigParser:

config = configparser.ConfigParser(dict_type=AttrDict)
config.read('application.ini')

and now we get application.ini with:

[general]
key = value

as

>>> config._sections.general.key
'value'
