I had the exact same problem, found that I was missing

<mdb>  
  <resource-adapter-ref resource-adapter-name="hornetq-ra"/>  
  <bean-instance-pool-ref pool-name="mdb-strict-max-pool"/>  
</mdb>  

under

<subsystem xmlns="urn:jboss:domain:ejb3:1.2">  

in standalone/configuration/standalone.xml

In case entire entity is being return, better solution in spring JPA is use @Query(value = "from entity where Id in :ids")

This return entity type rather than object type

I dont understand the frustrations. Why not just make a broadcastreceiver that filters for this intent:

android.provider.Telephony.MMS_RECEIVED

I checked a little further and you might need system level access to get this (rooted phone).

To add to ScottTx's answer, here's the actual code to start the service if you're doing it the Microsoft way (ie. using a Setup project etc...)

(excuse the VB.net code, but this is what I'm stuck with)

Private Sub ServiceInstaller1_AfterInstall(ByVal sender As System.Object, ByVal e As System.Configuration.Install.InstallEventArgs) Handles ServiceInstaller1.AfterInstall
    Dim sc As New ServiceController()
    sc.ServiceName = ServiceInstaller1.ServiceName

    If sc.Status = ServiceControllerStatus.Stopped Then
        Try
            ' Start the service, and wait until its status is "Running".
            sc.Start()
            sc.WaitForStatus(ServiceControllerStatus.Running)

            ' TODO: log status of service here: sc.Status
        Catch ex As Exception
            ' TODO: log an error here: "Could not start service: ex.Message"
            Throw
        End Try
    End If
End Sub

To create the above event handler, go to the ProjectInstaller designer where the 2 controlls are. Click on the ServiceInstaller1 control. Go to the properties window under events and there you'll find the AfterInstall event.

Note: Don't put the above code under the AfterInstall event for ServiceProcessInstaller1. It won't work, coming from experience. :)

You can't render a partial view using only jQuery. You can, however, call a method (action) that will render the partial view for you and add it to the page using jQuery/AJAX. In the below, we have a button click handler that loads the url for the action from a data attribute on the button and fires off a GET request to replace the DIV contained in the partial view with the updated contents.

$('.js-reload-details').on('click', function(evt) {
    evt.preventDefault();
    evt.stopPropagation();

    var $detailDiv = $('#detailsDiv'),
        url = $(this).data('url');

    $.get(url, function(data) {
        $detailDiv.replaceWith(data);         
    });
});

where the user controller has an action named details that does:

public ActionResult Details( int id )
{
    var model = ...get user from db using id...

    return PartialView( "UserDetails", model );
}

This is assuming that your partial view is a container with the id detailsDiv so that you just replace the entire thing with the contents of the result of the call.

Parent View Button

 <button data-url='@Url.Action("details","user", new { id = Model.ID } )'
         class="js-reload-details">Reload</button>

User is controller name and details is action name in @Url.Action(). UserDetails partial view

<div id="detailsDiv">
    <!-- ...content... -->
</div>

You can use the -d option with mysqldump command

mysqldump -u root -p -d databasename > database.sql

border: 0 should be enough, but if it isn't, perhaps the button's browser-default styling in interfering. Have you tried setting appearance to none (e.g. -webkit-appearance: none)

Not sure of exact syntax (you use varchar2 type which means not SQL Server hence TOP) but you can use the LIMIT keyword for MySQL:

Select * FROM test_table WHERE user_id = value
     ORDER BY DATE_ADDED DESC LIMIT 1

Or rownum in Oracle

 SELECT * FROM
     (Select rownum as rnum, * FROM test_table WHERE user_id = value ORDER BY DATE_ADDED DESC)
 WHERE rnum = 1

If DB2, I'm not sure whether it's TOP, LIMIT or rownum...

The ALTER TABLE MySQL command should do the trick. The following command will change the default character set of your table and the character set of all its columns to UTF8.

ALTER TABLE etape_prospection CONVERT TO CHARACTER SET utf8 COLLATE utf8_general_ci;

This command will convert all text-like columns in the table to the new character set. Character sets use different amounts of data per character, so MySQL will convert the type of some columns to ensure there's enough room to fit the same number of characters as the old column type.

I recommend you read the ALTER TABLE MySQL documentation before modifying any live data.

this jquery imageLoader plugin is just 1.39kb

usage:

$({}).imageLoader({
    images: [src1,src2,src3...],
    allcomplete:function(e,ui){
        //images are ready here
        //your code - site.fadeIn() or something like that
    }
});

there are also other options like whether you want to load the images synchronously or asychronously and a complete event for each individual image.

As stefanglase answered:

adding the following code to your build.gradle (since version 1.1) works fine for output on passed, skipped and failed tests.

test {
    testLogging {
        events "passed", "skipped", "failed", "standardOut", "standardError"
    }
}

What I want to say additionally (I found out this is a problem for starters) is that the gradle test command executes the test only one time per change.

So if you are running it the second time there will be no output on test results. You can also see this in the building output: gradle then says UP-TO-DATE on tests. So its not executed a n-th time.

Smart gradle!

If you want to force the test cases to run, use gradle cleanTest test.

This is slightly off topic but I hope it will help some newbies.

edit

As sparc_spread stated in the comments:

If you want to force gradle to always run fresh tests (which might not always be a good idea) you can add outputs.upToDateWhen {false} to testLogging { [...] }. Continue reading here.

Peace.

I generally prefer, where possible, to use the default value of value types to determine whether they've been set. This obviously isn't possible all the time, especially with ints - but for DateTimes, I think reserving the MinValue to signify that it hasn't been changed is fair enough. The benefit of this over nullables is that there's one less place where you'll get a null reference exception (and probably lots of places where you don't have to check for null before accessing it!)

You can do it like this, and no need to dedicate variable:

Toolbar toolbar = findViewById(R.id.toolbar);
Menu menu = toolbar.getMenu();
MenuItem menuItem = menu.findItem(R.id.some_action);
menuItem.setTitle("New title");

Or a little simplified:

MenuItem menuItem = ((Toolbar)findViewById(R.id.toolbar)).getMenu().findItem(R.id.some_action);
menuItem.setTitle("New title");

It works only - after the menu created.

Exact same thing, just omit the -c option. Apache's docs on it here.

htpasswd /etc/apache2/.htpasswd newuser

Also, htpasswd typically isn't run as root. It's typically owned by either the web server, or the owner of the files being served. If you're using root to edit it instead of logging in as one of those users, that's acceptable (I suppose), but you'll want to be careful to make sure you don't accidentally create a file as root (and thus have root own it and no one else be able to edit it).

My personal opinion is that, Biggest dis-advantage to using ASP.Net MVC is that CODE BLOCKS mixed with HTML...
html hell for the developers who maintain it...

It can also be due to a duplicate entry in any of the tables that are used.

Looking at your Erlang implementation. The timing has included the start up of the entire virtual machine, running your program and halting the virtual machine. Am pretty sure that setting up and halting the erlang vm takes some time.

If the timing was done within the erlang virtual machine itself, results would be different as in that case we would have the actual time for only the program in question. Otherwise, i believe that the total time taken by the process of starting and loading of the Erlang Vm plus that of halting it (as you put it in your program) are all included in the total time which the method you are using to time the program is outputting. Consider using the erlang timing itself which we use when we want to time our programs within the virtual machine itself timer:tc/1 or timer:tc/2 or timer:tc/3. In this way, the results from erlang will exclude the time taken to start and stop/kill/halt the virtual machine. That is my reasoning there, think about it, and then try your bench mark again.

I actually suggest that we try to time the program (for languages that have a runtime), within the runtime of those languages in order to get a precise value. C for example has no overhead of starting and shutting down a runtime system as does Erlang, Python and Haskell (98% sure of this - i stand correction). So (based on this reasoning) i conclude by saying that this benchmark wasnot precise /fair enough for languages running on top of a runtime system. Lets do it again with these changes.

EDIT: besides even if all the languages had runtime systems, the overhead of starting each and halting it would differ. so i suggest we time from within the runtime systems (for the languages for which this applies). The Erlang VM is known to have considerable overhead at start up!

Do this.

$(function(){
    var myFunction = function()
    {
        alert("myFunction called");
    }

    jQuery(':input').change(myFunction).keyup(myFunction);
});

With :after and :before you can do that.

HTML:

<div class="a"> </div>
<div class="b"> </div>
<div class="c"> </div>

CSS:

div {
    height: 100px;
    position: relative;
}
.a {
    background: #9C9E9F;
}
.b {
    background: linear-gradient(to right, #9c9e9f, #f6f6f6);
}
.a:after, .c:before, .c:after {
    content: '';
    width: 50%;
    height: 100%;
    top: 0;
    right: 0;
    display: block;
    position: absolute;
}
.a:after {
    background: #f6f6f6;    
}
.c:before {
    background: #9c9e9f;
    left: 0;
}
.c:after {
    background: #33CCFF;
    right: 0;
    height: 80%;
}

And a demo.

If you have cloned a project from GitHub for example, and you've tried the methods mentioned here without success including:

• Editing sdk.dir in the local.properties
• Trying to set ANDROID_HOME environment variable
• Or adding an alias as kasiara mentioned

You should try to see if you are trying to build a directory project that is a part within a bigger project, and so it may cause problems. So load the entire project, and then run the project directory you'd like.

for %f in (filenamewildcard0, filenamewildcard1, ...) do echo %f >> newtargetfilename_with_path

Same idea as Mike T; might work better under MessyDog's 127 character command line limit

Check whether you have matching IDs in both Java and XML

You can use the File.deleteOnExit() method

https://developer.android.com/reference/java/io/File.html#deleteOnExit()

It is referenced here https://developer.android.com/reference/java/io/File.html#createTempFile(java.lang.String, java.lang.String, java.io.File)

ArrayList: The ArrayList class extends AbstractList and implements the List interface and RandomAccess (marker interface). ArrayList supports dynamic arrays that can grow as needed. It gives us first iteration over elements.

LinkedList: A LinkedList is ordered by index position, like ArrayList, except that the elements are doubly-linked to one another. This linkage gives you new methods (beyond what you get from the List interface) for adding and removing from the beginning or end, which makes it an easy choice for implementing a stack or queue. Keep in mind that a LinkedList may iterate more slowly than an ArrayList, but it's a good choice when you need fast insertion and deletion. As of Java 5, the LinkedList class has been enhanced to implement the java.util.Queue interface. As such, it now supports the common queue methods: peek (), poll (), and offer ().

Unlike jQuery in order to read raw JSON you will need to decode it in PHP.

print_r(json_decode(file_get_contents("php://input"), true));

php://input is a read-only stream that allows you to read raw data from the request body.

$_POST is form variables, you will need to switch to form radiobutton in postman then use:

foo=bar&foo2=bar2

To post raw json with jquery:

$.ajax({
    "url": "/rest/index.php",
    'data': JSON.stringify({foo:'bar'}),
    'type': 'POST',
    'contentType': 'application/json'
});

Actually i am getting return value from a another sp into @temp and then it @temp =1 then i want to inc the count of @SelectoneCount by 1 and so on. Please let me know what is the correct syntax.

What's wrong with:

IF @Temp = 1 --Or @Temp = 2 also?
BEGIN
    SET @SelectoneCount = @SelectoneCount + 1
END

(Although this does reek of being procedural code - not usually the best way to use SQL)

This happens for these reasons:

1. your inner class should be defined as static

   private static class Condition {  //jackson specific    
   }
   

2. It might be that you got no default constructor in your class (UPDATE: This seems not to be the case)

   private static class Condition {
       private Long id;
   
       public Condition() {
       }
   
       // Setters and Getters
   }
   

3. It could be your Setters are not defined properly or are not visible (e.g. private setter)

<?xml version="1.0" encoding="utf-8"?>

<gradient
    android:angle="90"
    android:startColor="@color/colorPrimary"
    android:endColor="@color/colorPrimary"
    android:centerColor="@color/white"
    android:type="linear"/>

<corners android:bottomRightRadius="10dp"
    android:bottomLeftRadius="10dp"
    android:topRightRadius="10dp"
    android:topLeftRadius="10dp"/>

In RxJS 5+ you can do it like this

import { Observable } from "rxjs/Observable";
import { of } from "rxjs/observable/of";
import { delay } from "rxjs/operators";

fakeObservable = of('dummy').pipe(delay(5000));

In RxJS 6+

import { of } from "rxjs";
import { delay } from "rxjs/operators";

fakeObservable = of('dummy').pipe(delay(5000));

If you want to delay each emitted value try

from([1, 2, 3]).pipe(concatMap(item => of(item).pipe(delay(1000))));

In Manifest theme sets with style name (AppTheme and myDialog)/ You can set new styles in styles.xml

        <intent-filter>
            <action android:name="android.intent.action.MAIN" />

            <category android:name="android.intent.category.LAUNCHER" />
        </intent-filter>
    </activity>
    <activity
        android:name=".MyActivity2"
        android:label="@string/title_activity_my_activity2"
        android:theme="@style/myDialog"
        >
    </activity>
</application>

styles.xml example

<resources>

<!-- Base application theme. -->
<style name="AppTheme" parent="android:Theme.Black">
    <!-- Customize your theme here. -->
</style>

<style name="myDialog" parent="android:Theme.Dialog">

</style>

In parent you set actualy the theme

select previous, Present, previous-Present as Difference from tablename

or

select previous, Present, previous-Present as Difference from #TEMP1

An Object if passed as a value type then changes made to the members of the object inside the method are impacted outside the method also. But if the object itself is set to another object or reinitialized then it will not be reflected outside the method. So i would say object as a whole is passed as Valuetype only but object members are still reference type.

        private void button1_Click(object sender, EventArgs e)
    {
        Class1 objc ;
         objc = new Class1();
        objc.empName = "name1";
        checkobj( objc);
        MessageBox.Show(objc.empName);  //propert value changed; but object itself did not change
    }
    private void checkobj ( Class1 objc)
    {
        objc.empName = "name 2";
        Class1 objD = new Class1();
        objD.empName ="name 3";
        objc = objD ;
        MessageBox.Show(objc.empName);  //name 3
    }

HashMap<String, List<Integer>> map = new HashMap<String, List<Integer>>();
HashMap<String, int[]> map = new HashMap<String, int[]>();

pick one, for example

HashMap<String, List<Integer>> map = new HashMap<String, List<Integer>>();
map.put("Something", new ArrayList<Integer>());
for (int i=0;i<numarulDeCopii; i++) {
    map.get("Something").add(coeficientUzura[i]); 
}

or just

HashMap<String, int[]> map = new HashMap<String, int[]>();
map.put("Something", coeficientUzura);

I'm surprised nobody suggested using Applet. Use Applet. You'll have to supply the beep audio file as a wav file, but it works. I tried this on Ubuntu:

package javaapplication2;

import java.applet.Applet;
import java.applet.AudioClip;
import java.io.File;
import java.net.MalformedURLException;
import java.net.URL;

public class JavaApplication2 {

    public static void main(String[] args) throws MalformedURLException {
        File file = new File("/path/to/your/sounds/beep3.wav");
        URL url = null;
        if (file.canRead()) {url = file.toURI().toURL();}
        System.out.println(url);
        AudioClip clip = Applet.newAudioClip(url);
        clip.play();
        System.out.println("should've played by now");
    }
}
//beep3.wav was available from: http://www.pacdv.com/sounds/interface_sound_effects/beep-3.wav

By strange it can seem it works perfectly fine: date_create( '2016-02-01 + 1 day' );

echo date_create( $your_date . ' + 1 day' )->format( 'Y-m-d' );

Should do it

OrbitControls and TrackballControls seems to be good for this purpose.

controls = new THREE.TrackballControls( camera );
controls.rotateSpeed = 1.0;
controls.zoomSpeed = 1.2;
controls.panSpeed = 0.8;
controls.noZoom = false;
controls.noPan = false;
controls.staticMoving = true;
controls.dynamicDampingFactor = 0.3;

update in render

controls.update();

To create a read-only user, you have to setup a different user than the one owning the tables you want to access.

If you just create the user and grant SELECT permission to the read-only user, you'll need to prepend the schema name to each table name. To avoid this, you have basically two options:

1. Set the current schema in your session:

ALTER SESSION SET CURRENT_SCHEMA=XYZ

2. Create synonyms for all tables:

CREATE SYNONYM READER_USER.TABLE1 FOR XYZ.TABLE1

So if you haven't been told the name of the owner schema, you basically have three options. The last one should always work:

1. Query the current schema setting:

SELECT SYS_CONTEXT('USERENV','CURRENT_SCHEMA') FROM DUAL

2. List your synonyms:

SELECT * FROM ALL_SYNONYMS WHERE OWNER = USER

3. Investigate all tables (with the exception of the some well-known standard schemas):

SELECT * FROM ALL_TABLES WHERE OWNER NOT IN ('SYS', 'SYSTEM', 'CTXSYS', 'MDSYS');

I am on a 64 bit system, and I only got this to work after installing both the 32 and 64 bit versions of the redistributable. I did not try the 64 bit version by itself due to the other posters' warnings about using the 32 bit version (and am too lazy to uninstall the 32 bit version now that I have it working), so I don't know if the 32 bit version is needed or not in cases like mine.

Look before you leap (LBYL):

if idx < len(array):
    array[idx]
else:
    # handle this

Easier to ask forgiveness than permission (EAFP):

try:
    array[idx]
except IndexError:
    # handle this

In Python, EAFP seems to be the popular and preferred style. It is generally more reliable, and avoids an entire class of bugs (time of check vs. time of use). All other things being equal, the try/except version is recommended - don't see it as a "last resort".

This excerpt is from the official docs linked above, endorsing using try/except for flow control:

This common Python coding style assumes the existence of valid keys or attributes and catches exceptions if the assumption proves false. This clean and fast style is characterized by the presence of many try and except statements.

It is not improbable, that programmers looking for python on windows, also use the Python Tools for Visual Studio. In this case it is easy to install additional packages, by taking advantage of the included "Python Environment" Window. "Overview" is selected within the window as default. You can select "Pip" there.

Then you can install numpy without additional work by entering numpy into the seach window. The coresponding "install numpy" instruction is already suggested.

Nevertheless I had 2 easy to solve Problems in the beginning:

• "error: Unable to find vcvarsall.bat": This problem has been solved here. Although I did not find it at that time and instead installed the C++ Compiler for Python.
• Then the installation continued but failed because of an additional inner exception. Installing .NET 3.5 solved this.

Finally the installation was done. It took some time (5 minutes), so don't cancel the process to early.

This is worked with me

if (evt.xa.which == 3) 
{
    alert("Right mouse clicked");
}

I had same problem too this command works for me

Your assignment has an extra $:

export PATH=$PATH:${PWD}:/foo/bar

You can use:

Integer grandChildCount = ((BigInteger) result[1]).intValue();

Or perhaps cast to Number to cover both Integer and BigInteger values.

This is how it would be done in a loop in C++(11):

   for (const auto& attack : m_attack)
    {  
        if (attack->m_num == input)
        {
            attack->makeDamage();
        }
    }

There is no for each in C++. Another option is to use std::for_each with a suitable functor (this could be anything that can be called with an Attack* as argument).

String[] strarray = strlist.toArray(new String[0]);

if u want List convert to string use StringUtils.join(slist, '\n');

You can do it, but not at the point you've specified. Within the context of B, you may invoke A.X() by calling base.X().

I had some lint errors in Android Studio that occurred only when I generated a signed APK.

To avoid it, I added the following to build.gradle

android {
    lintOptions {
        checkReleaseBuilds false
    }
}

I achieved it using some extension methods

private const string endFieldPattern = "^(.*?)>";

    public static MvcHtmlString IsDisabled(this MvcHtmlString htmlString, bool disabled)
    {
        string rawString = htmlString.ToString();
        if (disabled)
        {
            rawString = Regex.Replace(rawString, endFieldPattern, "$1 disabled=\"disabled\">");
        }

        return new MvcHtmlString(rawString);
    }

    public static MvcHtmlString IsReadonly(this MvcHtmlString htmlString, bool @readonly)
    {
        string rawString = htmlString.ToString();
        if (@readonly)
        {
            rawString = Regex.Replace(rawString, endFieldPattern, "$1 readonly=\"readonly\">");
        }

        return new MvcHtmlString(rawString);
    }

and then....

@Html.TextBoxFor(model => model.Name, new { @class= "someclass"}).IsDisabled(Model.ExpireDate == null)

Since the original request is not say the solution had to be a RegExp, just that an attempt to use a RegExp was being made. I will offer this up. It says something is HTML if a single child element can be parsed. Note, this will return false if the body contains only comments or CDATA or server directives.

const isHTML = (text) => {
  try {
    const fragment = new DOMParser().parseFromString(text,"text/html");
    return fragment.body.children.length>0
  } catch(error) { ; }  
  return false;
}

Round down

function round_down(value, decPlaces) {
    return Math.floor(value * Math.pow(10, decPlaces)) / Math.pow(10, decPlaces);

    return Math.ceil(value * Math.pow(10, decPlaces)) / Math.pow(10, decPlaces);
}

Round nearest

function round_nearest(value, decPlaces) {
    return Math.round(value * Math.pow(10, decPlaces)) / Math.pow(10, decPlaces);
}

        System.out.println("Exception : "+e.getMessage());
    }
    System.out.println("Hello world!");
}

Note that the use of unescape() is deprecated and doesn't work with the TypeScript compiler, for example.

Based on radicand's answer and the comments section below, here's an updated solution:

var string = "http\\u00253A\\u00252F\\u00252Fexample.com";
decodeURIComponent(JSON.parse('"' + string.replace(/\"/g, '\\"') + '"'));

To perform Email Validation we have many ways,but simple & easiest way are two methods.

1- Using EditText(....).addTextChangedListener which keeps triggering on every input in an EditText box i.e email_id is invalid or valid

/**
 * Email Validation ex:- [email protected]
*/


final EditText emailValidate = (EditText)findViewById(R.id.textMessage); 

final TextView textView = (TextView)findViewById(R.id.text); 

String email = emailValidate.getText().toString().trim();

String emailPattern = "[a-zA-Z0-9._-]+@[a-z]+\\.+[a-z]+";

emailValidate .addTextChangedListener(new TextWatcher() { 
    public void afterTextChanged(Editable s) { 

    if (email.matches(emailPattern) && s.length() > 0)
        { 
            Toast.makeText(getApplicationContext(),"valid email address",Toast.LENGTH_SHORT).show();
            // or
            textView.setText("valid email");
        }
        else
        {
             Toast.makeText(getApplicationContext(),"Invalid email address",Toast.LENGTH_SHORT).show();
            //or
            textView.setText("invalid email");
        }
    } 
    public void beforeTextChanged(CharSequence s, int start, int count, int after) {
    // other stuffs 
    } 
    public void onTextChanged(CharSequence s, int start, int before, int count) {
    // other stuffs 
    } 
}); 

2- Simplest method using if-else condition. Take the EditText box string using getText() and compare with pattern provided for email. If pattern doesn't match or macthes, onClick of button toast a message. It ll not trigger on every input of an character in EditText box . simple example shown below.

final EditText emailValidate = (EditText)findViewById(R.id.textMessage); 

final TextView textView = (TextView)findViewById(R.id.text); 

String email = emailValidate.getText().toString().trim();

String emailPattern = "[a-zA-Z0-9._-]+@[a-z]+\\.+[a-z]+";

// onClick of button perform this simplest code.
if (email.matches(emailPattern))
{
Toast.makeText(getApplicationContext(),"valid email address",Toast.LENGTH_SHORT).show();
}
else 
{
Toast.makeText(getApplicationContext(),"Invalid email address", Toast.LENGTH_SHORT).show();
}

An alternative is to normalize the data. Below are three sets of data with widely varying ranges. In the top chart you can see the variation in one series clearly, in another not so clearly, and the third not at all.

In the second range, I have adjusted the series names to include the data range, using this formula in cell C15 and copying it to D15:E15

=C2&" ("&MIN(C3:C9)&" to "&MAX(C3:C9)&")"

I have normalized the values in the data range using this formula in C15 and copying it to the entire range C16:E22

=100*(C3-MIN(C$3:C$9))/(MAX(C$3:C$9)-MIN(C$3:C$9))

In the second chart, you can see a pattern: all series have a low in January, rising to a high in March, and dropping to medium-low value in June or July.

You can modify the normalizing formula however you need:

=100*C3/MAX(C$3:C$9)

=C3/MAX(C$3:C$9)

=(C3-AVERAGE(C$3:C$9))/STDEV(C$3:C$9)

etc.

If you take 5 minutes to download visual studio and make a Console Application for this, your problem is solved.

using System;
using System.Linq;
using System.Diagnostics;
using System.IO;

namespace BgRunner
{
    class Program
    {
        static void Main(string[] args)
        {
            Console.WriteLine("Starting: " + String.Join(" ", args));
            String arguments = String.Join(" ", args.Skip(1).ToArray());
            String command = args[0];

            Process p = new Process();
            p.StartInfo = new ProcessStartInfo(command);
            p.StartInfo.Arguments = arguments;
            p.StartInfo.WorkingDirectory = Path.GetDirectoryName(command);
            p.StartInfo.CreateNoWindow = true;
            p.StartInfo.UseShellExecute = false;
            p.Start();
        }
    }
}

Examples of usage:

BgRunner.exe php/php-cgi -b 9999
BgRunner.exe redis/redis-server --port 3000
BgRunner.exe nginx/nginx

I've implemented a version where it basically finds all possible paths from one node to the other, but it doesn't count any possible 'cycles' (the graph I'm using is cyclical). So basically, no one node will appear twice within the same path. And if the graph were acyclical, then I suppose you could say it seems to find all the possible paths between the two nodes. It seems to be working just fine, and for my graph size of ~150, it runs almost instantly on my machine, though I'm sure the running time must be something like exponential and so it'll start to get slow quickly as the graph gets bigger.

Here is some Java code that demonstrates what I'd implemented. I'm sure there must be more efficient or elegant ways to do it as well.

Stack connectionPath = new Stack();
List<Stack> connectionPaths = new ArrayList<>();
// Push to connectionsPath the object that would be passed as the parameter 'node' into the method below
void findAllPaths(Object node, Object targetNode) {
    for (Object nextNode : nextNodes(node)) {
       if (nextNode.equals(targetNode)) {
           Stack temp = new Stack();
           for (Object node1 : connectionPath)
               temp.add(node1);
           connectionPaths.add(temp);
       } else if (!connectionPath.contains(nextNode)) {
           connectionPath.push(nextNode);
           findAllPaths(nextNode, targetNode);
           connectionPath.pop();
        }
    }
}

How to echo key and value of an array without and with loop

I was able to implement Luca's solution, but I had to make a few changes for it to work. My goal was to use D3.js with a Web Browser control for a Windows Forms Application (targeting .NET 2.0). It is working for me now. I hope this can help someone else.

using System;
using System.Collections.Generic;
using System.Windows.Forms;
using System.Threading;
using Microsoft.Win32;
using System.Diagnostics;

namespace ClientUI
{
    static class Program
    {
        static Mutex mutex = new System.Threading.Mutex(false, "jMutex");

        /// <summary>
        /// The main entry point for the application.
        /// </summary>
        [STAThread]
        static void Main()
        {
            if (!mutex.WaitOne(TimeSpan.FromSeconds(2), false))
            {
                // Another application instance is running
                return;
            }
            try
            {
                Application.EnableVisualStyles();
                Application.SetCompatibleTextRenderingDefault(false);

                var targetApplication = Process.GetCurrentProcess().ProcessName + ".exe";
                int ie_emulation = 11999;
                try
                {
                    string tmp = Properties.Settings.Default.ie_emulation;
                    ie_emulation = int.Parse(tmp);
                }
                catch { }
                SetIEVersioneKeyforWebBrowserControl(targetApplication, ie_emulation);

                Application.Run(new MainForm());
            }
            finally
            {
                mutex.ReleaseMutex();
            }
        }

        private static void SetIEVersioneKeyforWebBrowserControl(string appName, int ieval)
        {
            RegistryKey Regkey = null;
            try
            {
                Regkey = Microsoft.Win32.Registry.LocalMachine.OpenSubKey(@"SOFTWARE\Microsoft\Internet Explorer\Main\FeatureControl\FEATURE_BROWSER_EMULATION", true);

                // If the path is not correct or
                // if user doesn't have privileges to access the registry
                if (Regkey == null)
                {
                    MessageBox.Show("Application FEATURE_BROWSER_EMULATION Failed - Registry key Not found");
                    return;
                }

                string FindAppkey = Convert.ToString(Regkey.GetValue(appName));

                // Check if key is already present
                if (FindAppkey == ieval.ToString())
                {
                    MessageBox.Show("Application FEATURE_BROWSER_EMULATION already set to " + ieval);
                    Regkey.Close();
                    return;
                }

                // If key is not present or different from desired, add/modify the key , key value
                Regkey.SetValue(appName, unchecked((int)ieval), RegistryValueKind.DWord);

                // Check for the key after adding
                FindAppkey = Convert.ToString(Regkey.GetValue(appName));

                if (FindAppkey == ieval.ToString())
                {
                    MessageBox.Show("Application FEATURE_BROWSER_EMULATION changed to " + ieval + "; changes will be visible at application restart");
                }
                else
                {
                    MessageBox.Show("Application FEATURE_BROWSER_EMULATION setting failed; current value is  " + ieval);
                }
            }
            catch (Exception ex)
            {
                MessageBox.Show("Application FEATURE_BROWSER_EMULATION setting failed; " + ex.Message);
            }
            finally
            {
                //Close the Registry
                if (Regkey != null) Regkey.Close();
            }
        }
    }
}

Also, I added a string (ie_emulation) to the project's settings with the value of 11999. This value seems to be working for IE11(11.0.15).

Next, I had to change the permission for my application to allow access to the registry. This can be done by adding a new item to your project (using VS2012). Under the General Items, select Application Manifest File. Change the level from asInvoker to requireAdministrator (as shown below).

<requestedExecutionLevel level="requireAdministrator" uiAccess="false" />

If someone reading this is trying to use D3.js with a webbrowser control, you may have to modify the JSON data to be stored within a variable inside your HTML page because D3.json uses XmlHttpRequest (easier to use with a webserver). After those changes and the above, my windows forms are able to load local HTML files that call D3.

The command free is nice. Takes a short while to understand the "+/- buffers/cache", but the idea is that cache and buffers doesn't really count when evaluating "free", as it can be dumped right away. Therefore, to see how much free (and used) memory you have, you need to remove the cache/buffer usage - which is conveniently done for you.

One way we do this in our application is using IDisposable and then with using(){} blocks to ensure the cursor is reset when done.

public class OverrideCursor : IDisposable
{

  public OverrideCursor(Cursor changeToCursor)
  {
    Mouse.OverrideCursor = changeToCursor;
  }

  #region IDisposable Members

  public void Dispose()
  {
    Mouse.OverrideCursor = null;
  }

  #endregion
}

and then in your code:

using (OverrideCursor cursor = new OverrideCursor(Cursors.Wait))
{
  // Do work...
}

The override will end when either: the end of the using statement is reached or; if an exception is thrown and control leaves the statement block before the end of the statement.

Update

To prevent the cursor flickering you can do:

public class OverrideCursor : IDisposable
{
  static Stack<Cursor> s_Stack = new Stack<Cursor>();

  public OverrideCursor(Cursor changeToCursor)
  {
    s_Stack.Push(changeToCursor);

    if (Mouse.OverrideCursor != changeToCursor)
      Mouse.OverrideCursor = changeToCursor;
  }

  public void Dispose()
  {
    s_Stack.Pop();

    Cursor cursor = s_Stack.Count > 0 ? s_Stack.Peek() : null;

    if (cursor != Mouse.OverrideCursor)
      Mouse.OverrideCursor = cursor;
  }

}

I have had the same problem.

In my case, since I have the original repository in my local machine, I have made a copy in a new folder without any hidden file (.git, .gitignore).

Finally I have added the .gitignore file to the new created folder.

Then I have created and added the new repository from the local path (in my case using GitHub Desktop).

What you are talking about is the way a parameterized query is written. '@' just signifies that it is a parameter. You can add the value for that parameter during execution process

eg:
sqlcommand cmd = new sqlcommand(query,connection);
cmd.parameters.add("@custid","1");
sqldatareader dr = cmd.executequery();

To answer your original question, here's how you do it with sed:

sed -i '1icolumn1, column2, column3' testfile.csv

The "1i" command tells sed to go to line 1 and insert the text there.

The -i option causes the file to be edited "in place" and can also take an optional argument to create a backup file, for example

sed -i~ '1icolumn1, column2, column3' testfile.csv

would keep the original file in "testfile.csv~".

I'm guessing the reason you're asking is performance? There's the instr function. But that's likely to work pretty much the same behind the scenes.

Maybe you could look into full text search.

As last resorts you'd be looking at caching or precomputed columns/an indexed view.

Here's a one-line version with a few useful properties:

1. Handles any form of space matched by the \s regex
2. Performs independent of input length (anything past the max length is not scanned)
3. Performs independent of output length (scans backward from max length and doesn't split/join the string)

s.length > maxLen ? s.substring(0, s.substring(0, maxLen + 1).search(/\s+\S*$/)) : s

Once you install Homebrew, type command brew doctor in terminal.

• If you get the following message:

  Your system is ready to brew

  then you are good to go and you have successfully installed homebrew.

• If you get any warnings, you can try fixing it.

you need

if (title == "User greeting" || title == "User name") {do stuff};

Close to BalusC answer in 4 simple lines using Google Gson lib. Add this lines to the servlet method:

User objToSerialize = new User("Bill", "Gates");    
ServletOutputStream outputStream = response.getOutputStream();

response.setContentType("application/json;charset=UTF-8");
outputStream.print(new Gson().toJson(objToSerialize));

Good luck!

I was ultimately able to resolve the solution by setting the column type in the flat file connection to be of type "database date [DT_DBDATE]"

Apparently the differences between these date formats are as follow:

DT_DATE A date structure that consists of year, month, day, and hour.

DT_DBDATE A date structure that consists of year, month, and day.

DT_DBTIMESTAMP A timestamp structure that consists of year, month, hour, minute, second, and fraction

By changing the column type to DT_DBDATE the issue was resolved - I attached a Data Viewer and the CYCLE_DATE value was now simply "12/20/2010" without a time component, which apparently resolved the issue.

MobileESP has PHP, Java, APS.NET (C#), Ruby and JavaScript hooks. it has also the Apache 2 licence, so free for commercial use. Key thing for me is it only identifies browsers and platforms not screen sizes and other metrics, which keeps it nice an small.

In June 2014 RFC7231 obsoletes RFC2616. If you are doing REST over HTTP then RFC7231 describes exactly what behaviour is expected from GET, PUT, POST and DELETE

<script type="text/javascript">
  $(function() {
    $( "#date" ).datepicker( {minDate: '0', dateFormat: 'yy-dd-mm' } );
  });
</script>

Webkit based browsers (like Google Chrome or Safari) has built-in developer tools. In Chrome you can open it Menu->Tools->Developer Tools. The Network tab allows you to see all information about every request and response:

In the bottom of the picture you can see that I've filtered request down to XHR - these are requests made by javascript code.

Tip: log is cleared every time you load a page, at the bottom of the picture, the black dot button will preserve log.

After analyzing requests and responses you can simulate these requests from your web-crawler and extract valuable data. In many cases it will be easier to get your data than parsing HTML, because that data does not contain presentation logic and is formatted to be accessed by javascript code.

Firefox has similar extension, it is called firebug. Some will argue that firebug is even more powerful but I like the simplicity of webkit.

Unfortunately these new bootstrap 4 classes do not work like the old ones on a div using collapse as they set the visible div to block which starts out visible rather than hidden and if you add an extra div around the collapse functionality no longer works.

and first of all I appreciate you for posting your doubt. It's mainly because maybe your expo or the app in which you run your react native project may not be in the same local connected wifi or LAN. Also, there is a chance that there is disturbance in your connection frequently due to which it loses its connectivity.

I too face this problem and I personally clear the cache and then restart again and boom it restarts perfectly. I hope this works for you too!

With data.table, the solutions is:

DT[, idnat2 := ifelse(idbp %in% "foreign", "foreign", 
        ifelse(idbp %in% c("colony", "overseas"), "overseas", "mainland" ))]

The ifelse is vectorized. The if-else is not. Here, DT is:

    idnat     idbp
1  french mainland
2  french   colony
3  french overseas
4 foreign  foreign

This gives:

   idnat     idbp   idnat2
1:  french mainland mainland
2:  french   colony overseas
3:  french overseas overseas
4: foreign  foreign  foreign

I realize this is a little old, but, yes it can be done. Some javascript to get you started:

viewport = document.querySelector("meta[name=viewport]");
viewport.setAttribute('content', 'width=device-width, initial-scale=1.0, maximum-scale=1.0, user-scalable=0');

Just change the parts you need and Mobile Safari will respect the new settings.

Update:

If you don't already have the meta viewport tag in the source, you can append it directly with something like this:

var metaTag=document.createElement('meta');
metaTag.name = "viewport"
metaTag.content = "width=device-width, initial-scale=1.0, maximum-scale=1.0, user-scalable=0"
document.getElementsByTagName('head')[0].appendChild(metaTag);

Or if you're using jQuery:

$('head').append('<meta name="viewport" content="width=device-width, initial-scale=1.0, maximum-scale=1.0, user-scalable=0">');

Async functions are not supported by Node versions older than version 7.6.

You'll need to transpile your code (e.g. using Babel) to a version of JS that Node understands if you are using an older version.

That said, the current (2018) LTS version of Node.js is 8.x, so if you are using an earlier version you should very strongly consider upgrading.

If you want to get advantage of your local machine timezone you can use myDateTime.ToUniversalTime() to get the UTC time from your local time or myDateTime.ToLocalTime() to convert the UTC time to the local machine's time.

// convert UTC time from the database to the machine's time
DateTime databaseUtcTime = new DateTime(2011,6,5,10,15,00);
var localTime = databaseUtcTime.ToLocalTime();

// convert local time to UTC for database save
var databaseUtcTime = localTime.ToUniversalTime();

If you need to convert time from/to other timezones, you may use TimeZoneInfo.ConvertTime() or TimeZoneInfo.ConvertTimeFromUtc().

// convert UTC time from the database to japanese time
DateTime databaseUtcTime = new DateTime(2011,6,5,10,15,00);
var japaneseTimeZone = TimeZoneInfo.FindSystemTimeZoneById("Tokyo Standard Time");
var japaneseTime = TimeZoneInfo.ConvertTimeFromUtc(databaseUtcTime, japaneseTimeZone);

// convert japanese time to UTC for database save
var databaseUtcTime = TimeZoneInfo.ConvertTimeToUtc(japaneseTime, japaneseTimeZone);

Yep, you can use border: 1px solid transparent

Another solution is to use outline on hover (and set the border to 0) which doesn't affect the document flow:

li{
    display:inline-block;
    padding:5px;
    border:0;
}
li:hover{
    outline:1px solid #FC0;
}

NB. You can only set the outline as a sharthand property, not for individual sides. It's only meant to be used for debugging but it works nicely.

There must be a user in the AllowUsers section, in the config file /etc/ssh/ssh_config, in the remote machine. You might have to restart sshd after editing the config file.

And then you can copy for example the file "test.txt" from a remote host to the local host

scp [email protected]:test.txt /local/dir

@cool_cs you can user ~ symbol ~/Users/djorge/Desktop if it's your home dir.

In UNIX, absolute paths must start with '/'.

To get class name you can use ReflectionClass

class MyClass {
    public function myNameIs(){
        return (new \ReflectionClass($this))->getShortName();
    }
}

If you are planning to use the code in a production web application code,
using any web framework like Django/Flask, use projects like envparse, using it you can read the value as your defined type.

from envparse import env
# will read WHITE_LIST=hello,world,hi to white_list = ["hello", "world", "hi"]
white_list = env.list("WHITE_LIST", default=[]) 
# Perfect for reading boolean
DEBUG = env.bool("DEBUG", default=False)

NOTE: kennethreitz's autoenv is a recommended tool for making project specific environment variables, please note that those who are using autoenv please keep the .env file private (inaccessible to public)

In terms of cost, using a web-service (API) may in many cases be the more sensible approach. Plus, by outsourcing this process you unburden your own infrastructure/backend and - provided you are using a reputable service - ensure compatibility with adjusting web standards, uptime, short processing times and quick content delivery.

I've done some research on most of the web services currently on the market, please find below the APIs that I feel are worth mentioning on this thread, in an order based on price/value ratio. All of them are offering pre-composed PHP classes and packages.

1. pdflayer.com - Cost: $ - Quality: ????
2. docraptor.com - Cost: $$$ - Quality: ?????
3. pdfcrowd.com - Cost: $$ - Quality: ???

Quality:

Having the high-quality engine PrinceXML as a backbone, DocRaptor clearly offers the best PDF quality, returning highly polished and well converted PDF documents. However, the pdflayer API service gets pretty close here. Pdfcrowd does not necessarily score with quality, but with processing speed.

Cost:

pdflayer.com - As indicated above, the most cost-effective option here is pdflayer.com, offering an entirely free subscription plan for 100 monthly PDFs and premium subscriptions ranging between $9.99-$119.99. The price for 10,000 monthly PDF documents is $39.99.

docraptor.com - Offering a 7-Day Free Trial period. Premium subscription plans range from $15-$2250. The price for 10,000 monthly PDF documents is ~ $300.00.

pdfcrowd.com - Offering 100 PDFs once for free. Premium subscription plans range from $9-$89. The price for 10,000 monthly PDF documents is ~ $49.00.

I've used all three of them and this text is supposed to help anyone decide without having to pay for all of them. This text has not been written to endorse any one product and I have no affiliation with any of the products.

Try using this Function.It Will help You:-

public class Main {   
public static void main(String args[]) 
 {        
  Date today=new Date();                     
  Date myDate=new Date(today.getYear(),today.getMonth()-1,today.getDay());
  System.out.println("My Date is"+myDate);    
  System.out.println("Today Date is"+today);
  if(today.compareTo(myDate)<0)
     System.out.println("Today Date is Lesser than my Date");
  else if(today.compareTo(myDate)>0)
     System.out.println("Today Date is Greater than my date"); 
  else
     System.out.println("Both Dates are equal");      
  }
}

What you want to do is called "serialization". There are several ways of doing it, but if you don't need anything fancy I think using the standard Java object serialization would do just fine.

Perhaps you could use something like this?

package com.example;

import java.io.ByteArrayInputStream;
import java.io.ByteArrayOutputStream;
import java.io.IOException;
import java.io.ObjectInputStream;
import java.io.ObjectOutputStream;

public class Serializer {

    public static byte[] serialize(Object obj) throws IOException {
        try(ByteArrayOutputStream b = new ByteArrayOutputStream()){
            try(ObjectOutputStream o = new ObjectOutputStream(b)){
                o.writeObject(obj);
            }
            return b.toByteArray();
        }
    }

    public static Object deserialize(byte[] bytes) throws IOException, ClassNotFoundException {
        try(ByteArrayInputStream b = new ByteArrayInputStream(bytes)){
            try(ObjectInputStream o = new ObjectInputStream(b)){
                return o.readObject();
            }
        }
    }

}

There are several improvements to this that can be done. Not in the least the fact that you can only read/write one object per byte array, which might or might not be what you want.

Note that "Only objects that support the java.io.Serializable interface can be written to streams" (see java.io.ObjectOutputStream).

Since you might run into it, the continuous allocation and resizing of the java.io.ByteArrayOutputStream might turn out to be quite the bottle neck. Depending on your threading model you might want to consider reusing some of the objects.

For serialization of objects that do not implement the Serializable interface you either need to write your own serializer, for example using the read*/write* methods of java.io.DataOutputStream and the get*/put* methods of java.nio.ByteBuffer perhaps together with reflection, or pull in a third party dependency.

This site has a list and performance comparison of some serialization frameworks. Looking at the APIs it seems Kryo might fit what you need.

You can use Vue.nextTick

addToBasket: function(){
                item = this.photo;
                this.$http.post('/api/buy/addToBasket', item);
                this.basketAddSuccess = true;
                Vue.nextTick(() =>{
                    this.basketAddSuccess = false;
                });
            }

If you have an Order class, adding a property that references another class in your model, for instance Customer should be enough to let EF know there's a relationship in there:

public class Order
{
    public int ID { get; set; }

    // Some other properties

    // Foreign key to customer
    public virtual Customer Customer { get; set; }
}

You can always set the FK relation explicitly:

public class Order
{
    public int ID { get; set; }

    // Some other properties

    // Foreign key to customer
    [ForeignKey("Customer")]
    public string CustomerID { get; set; }
    public virtual Customer Customer { get; set; }
}

The ForeignKeyAttribute constructor takes a string as a parameter: if you place it on a foreign key property it represents the name of the associated navigation property. If you place it on the navigation property it represents the name of the associated foreign key.

What this means is, if you where to place the ForeignKeyAttribute on the Customer property, the attribute would take CustomerID in the constructor:

public string CustomerID { get; set; }
[ForeignKey("CustomerID")]
public virtual Customer Customer { get; set; }

EDIT based on Latest Code You get that error because of this line:

[ForeignKey("Parent")]
public Patient Patient { get; set; }

EF will look for a property called Parent to use it as the Foreign Key enforcer. You can do 2 things:

1) Remove the ForeignKeyAttribute and replace it with the RequiredAttribute to mark the relation as required:

[Required]
public virtual Patient Patient { get; set; }

Decorating a property with the RequiredAttribute also has a nice side effect: The relation in the database is created with ON DELETE CASCADE.

I would also recommend making the property virtual to enable Lazy Loading.

2) Create a property called Parent that will serve as a Foreign Key. In that case it probably makes more sense to call it for instance ParentID (you'll need to change the name in the ForeignKeyAttribute as well):

public int ParentID { get; set; }

In my experience in this case though it works better to have it the other way around:

[ForeignKey("Patient")]
public int ParentID { get; set; }

public virtual Patient Patient { get; set; }

C++11 (Source: Iterator Invalidation Rules (C++0x))

Insertion

Sequence containers

• vector: all iterators and references before the point of insertion are unaffected, unless the new container size is greater than the previous capacity (in which case all iterators and references are invalidated) [23.3.6.5/1]
• deque: all iterators and references are invalidated, unless the inserted member is at an end (front or back) of the deque (in which case all iterators are invalidated, but references to elements are unaffected) [23.3.3.4/1]
• list: all iterators and references unaffected [23.3.5.4/1]
• forward_list: all iterators and references unaffected (applies to insert_after) [23.3.4.5/1]
• array: (n/a)

Associative containers

• [multi]{set,map}: all iterators and references unaffected [23.2.4/9]

Unsorted associative containers

• unordered_[multi]{set,map}: all iterators invalidated when rehashing occurs, but references unaffected [23.2.5/8]. Rehashing does not occur if the insertion does not cause the container's size to exceed z * B where z is the maximum load factor and B the current number of buckets. [23.2.5/14]

Container adaptors

• stack: inherited from underlying container
• queue: inherited from underlying container
• priority_queue: inherited from underlying container

Erasure

Sequence containers

• vector: every iterator and reference at or after the point of erase is invalidated [23.3.6.5/3]
• deque: erasing the last element invalidates only iterators and references to the erased elements and the past-the-end iterator; erasing the first element invalidates only iterators and references to the erased elements; erasing any other elements invalidates all iterators and references (including the past-the-end iterator) [23.3.3.4/4]
• list: only the iterators and references to the erased element is invalidated [23.3.5.4/3]
• forward_list: only the iterators and references to the erased element is invalidated (applies to erase_after) [23.3.4.5/1]
• array: (n/a)

Associative containers

• [multi]{set,map}: only iterators and references to the erased elements are invalidated [23.2.4/9]

Unordered associative containers

• unordered_[multi]{set,map}: only iterators and references to the erased elements are invalidated [23.2.5/13]

Container adaptors

• stack: inherited from underlying container
• queue: inherited from underlying container
• priority_queue: inherited from underlying container

Resizing

• vector: as per insert/erase [23.3.6.5/12]
• deque: as per insert/erase [23.3.3.3/3]
• list: as per insert/erase [23.3.5.3/1]
• forward_list: as per insert/erase [23.3.4.5/25]
• array: (n/a)

Note 1

Unless otherwise specified (either explicitly or by defining a function in terms of other functions), invoking a container member function or passing a container as an argument to a library function shall not invalidate iterators to, or change the values of, objects within that container. [23.2.1/11]

Note 2

no swap() function invalidates any references, pointers, or iterators referring to the elements of the containers being swapped. [ Note: The end() iterator does not refer to any element, so it may be invalidated. —end note ] [23.2.1/10]

Note 3

Other than the above caveat regarding swap(), it's not clear whether "end" iterators are subject to the above listed per-container rules; you should assume, anyway, that they are.

Note 4

vector and all unordered associative containers support reserve(n) which guarantees that no automatic resizing will occur at least until the size of the container grows to n. Caution should be taken with unordered associative containers because a future proposal will allow the specification of a minimum load factor, which would allow rehashing to occur on insert after enough erase operations reduce the container size below the minimum; the guarantee should be considered potentially void after an erase.

A simple DIY way would be to make the grid yourself:

import matplotlib.pyplot as plt

fig = plt.figure()
ax = fig.add_subplot(111)

ax.plot([1,2,3], [2,3,4], 'ro')

for xmaj in ax.xaxis.get_majorticklocs():
  ax.axvline(x=xmaj, ls='-')
for xmin in ax.xaxis.get_minorticklocs():
  ax.axvline(x=xmin, ls='--')

for ymaj in ax.yaxis.get_majorticklocs():
  ax.axhline(y=ymaj, ls='-')
for ymin in ax.yaxis.get_minorticklocs():
  ax.axhline(y=ymin, ls='--')
plt.show()

I would open another terminal on your laptop and do the scp from there, since you already know how to set that connection up.

scp username@remotecomputer:/path/to/file/you/want/to/copy where/to/put/file/on/laptop

The username@remotecomputer is the same string you used with ssh initially.

This exception can also happen if the layout ID which you are passing to FragmentTransaction.replace(int ID, fragment) exists in other layouts that are being inflated. Make sure the layout ID is unique and it should work.

HTTP interceptors are now available via the new HttpClient from @angular/common/http, as of Angular 4.3.x versions and beyond.

It's pretty simple to add a header for every request now:

import {
  HttpEvent,
  HttpInterceptor,
  HttpHandler,
  HttpRequest,
} from '@angular/common/http';
import { Observable } from 'rxjs';
 
export class AddHeaderInterceptor implements HttpInterceptor {
  intercept(req: HttpRequest<any>, next: HttpHandler): Observable<HttpEvent<any>> {
    // Clone the request to add the new header
    const clonedRequest = req.clone({ headers: req.headers.append('Authorization', 'Bearer 123') });

    // Pass the cloned request instead of the original request to the next handle
    return next.handle(clonedRequest);
  }
}

There's a principle of immutability, that's the reason the request needs to be cloned before setting something new on it.

As editing headers is a very common task, there's actually a shortcut for it (while cloning the request):

const clonedRequest = req.clone({ setHeaders: { Authorization: 'Bearer 123' } });

After creating the interceptor, you should register it using the HTTP_INTERCEPTORS provide.

import { HTTP_INTERCEPTORS } from '@angular/common/http';

@NgModule({
  providers: [{
    provide: HTTP_INTERCEPTORS,
    useClass: AddHeaderInterceptor,
    multi: true,
  }],
})
export class AppModule {}

The <button> element, when placed in a form, will submit the form automatically unless otherwise specified. You can use the following 2 strategies:

1. Use <button type="button"> to override default submission behavior
2. Use event.preventDefault() in the onSubmit event to prevent form submission

Solution 1:

• Advantage: simple change to markup
• Disadvantage: subverts default form behavior, especially when JS is disabled. What if the user wants to hit "enter" to submit?

Insert extra type attribute to your button markup:

<button id="button" type="button" value="send" class="btn btn-primary">Submit</button>

Solution 2:

• Advantage: form will work even when JS is disabled, and respects standard form UI/UX such that at least one button is used for submission

Prevent default form submission when button is clicked. Note that this is not the ideal solution because you should be in fact listening to the submit event, not the button click event:

$(document).ready(function () {
  // Listen to click event on the submit button
  $('#button').click(function (e) {

    e.preventDefault();

    var name = $("#name").val();
    var email = $("#email").val();

    $.post("process.php", {
      name: name,
      email: email
    }).complete(function() {
        console.log("Success");
      });
  });
});

Better variant:

In this improvement, we listen to the submit event emitted from the <form> element:

$(document).ready(function () {
  // Listen to submit event on the <form> itself!
  $('#main').submit(function (e) {

    e.preventDefault();

    var name = $("#name").val();
    var email = $("#email").val();

    $.post("process.php", {
      name: name,
      email: email
    }).complete(function() {
        console.log("Success");
      });
  });
});

Even better variant: use .serialize() to serialize your form, but remember to add name attributes to your input:

The name attribute is required for .serialize() to work, as per jQuery's documentation:

For a form element's value to be included in the serialized string, the element must have a name attribute.

<input type="text" id="name" name="name" class="form-control mb-2 mr-sm-2 mb-sm-0" id="inlineFormInput" placeholder="Jane Doe">
<input type="text" id="email" name="email" class="form-control" id="inlineFormInputGroup" placeholder="[email protected]">

And then in your JS:

$(document).ready(function () {
  // Listen to submit event on the <form> itself!
  $('#main').submit(function (e) {

    // Prevent form submission which refreshes page
    e.preventDefault();

    // Serialize data
    var formData = $(this).serialize();

    // Make AJAX request
    $.post("process.php", formData).complete(function() {
      console.log("Success");
    });
  });
});

In my case, I pushed several big (> 100Mb) files and then proceeded to remove them. But they were still in the history of my repo, so I had to remove them from it as well.

What did the trick was:

bfg -b 100M  # To remove all blobs from history, whose size is superior to 100Mb
git reflog expire --expire=now --all
git gc --prune=now --aggressive

Then, you need to push force on your branch:

git push origin <your_branch_name> --force

Note: bfg is a tool that can be installed on Linux and macOS using brew:

brew install bfg

The first solution works well. I want to add one small detail here. Make sure the variable you are trying to replace/update it will has to be a type str. My mysql type is decimal but I had to make the parameter variable as str to be able to execute the query.

temp = "100"
myCursor.execute("UPDATE testDB.UPS SET netAmount = %s WHERE auditSysNum = '42452'",(temp,))
myCursor.execute(var)

You can convert a numpy array to list and get its index .

for example:

tmp = [1,2,3,4,5] #python list
a = numpy.array(tmp) #numpy array
i = list(a).index(2) # i will return index of 2, which is 1

this is just what you wanted.

I know this question is a few years old, but as Java 8 has, in the meantime, brought us Optional, I thought I'd offer up a solution using it (and Stream and Collectors):

public enum PcapLinkType {
  DLT_NULL(0),
  DLT_EN3MB(2),
  DLT_AX25(3),
  /*snip, 200 more enums, not always consecutive.*/
  // DLT_UNKNOWN(-1); // <--- NO LONGER NEEDED

  private final int value;
  private PcapLinkType(int value) { this.value = value; }

  private static final Map<Integer, PcapLinkType> map;
  static {
    map = Arrays.stream(values())
        .collect(Collectors.toMap(e -> e.value, e -> e));
  }

  public static Optional<PcapLinkType> fromInt(int value) {
    return Optional.ofNullable(map.get(value));
  }
}

Optional is like null: it represents a case when there is no (valid) value. But it is a more type-safe alternative to null or a default value such as DLT_UNKNOWN because you could forget to check for the null or DLT_UNKNOWN cases. They are both valid PcapLinkType values! In contrast, you cannot assign an Optional<PcapLinkType> value to a variable of type PcapLinkType. Optional makes you check for a valid value first.

Of course, if you want to retain DLT_UNKNOWN for backward compatibility or whatever other reason, you can still use Optional even in that case, using orElse() to specify it as the default value:

public enum PcapLinkType {
  DLT_NULL(0),
  DLT_EN3MB(2),
  DLT_AX25(3),
  /*snip, 200 more enums, not always consecutive.*/
  DLT_UNKNOWN(-1);

  private final int value;
  private PcapLinkType(int value) { this.value = value; }

  private static final Map<Integer, PcapLinkType> map;
  static {
    map = Arrays.stream(values())
        .collect(Collectors.toMap(e -> e.value, e -> e));
  }

  public static PcapLinkType fromInt(int value) {
    return Optional.ofNullable(map.get(value)).orElse(DLT_UNKNOWN);
  }
}

You can use the following commands to open a file in git bash:

vi <filename>               -- to open a file

i                           -- to insert into the file 

ESC button followed by :wq   -- to save and close the file 

Hope it helps.

Any other terminal based text editor, like vim, nano and many will also do the job just fine.

You can't format the Date itself. You can only get the formatted result in String. Use SimpleDateFormat as mentioned by others.

Moreover, most of the getter methods in Date are deprecated.

I was having the same issue, and for me it worked by simply concatenating https:${image.getAttribute('src')}

@dev-nish Your code works with little tweaks in them. make the

const navigationExtras: NavigationExtras = {
  state: {
    transd: 'TRANS001',
    workQueue: false,
    services: 10,
    code: '003'
  }
};

into

let navigationExtras: NavigationExtras = {
  state: {
    transd: '',
    workQueue: ,
    services: ,
    code: ''
  }
};

then if you want to specifically sent a type of data, for example, JSON as a result of a form fill you can send the data in the same way as explained before.

I found this solution to be quite handy. It uses the -or option in find:

find . -name \*.tex -or -name "*.png" -or -name "*.pdf"

It will find the files with extension tex, png, and pdf.

There is a way to turn the validation back to 2.0 for one page. Just add the below code to your web.config:

<configuration>
    <location path="XX/YY">
        <system.web>
            <httpRuntime requestValidationMode="2.0" />
        </system.web>
    </location>

    ...
    the rest of your configuration
    ...

</configuration>

I used the properties plugin to solve this.

Properties are defined in the pom, and written out to a my.properties file, where they can then be accessed from your Java code.

In my case it is test code that needs to access this properties file, so in the pom the properties file is written to maven's testOutputDirectory:

<configuration>
    <outputFile>${project.build.testOutputDirectory}/my.properties</outputFile>
</configuration>

Use outputDirectory if you want properties to be accessible by your app code:

<configuration>
    <outputFile>${project.build.outputDirectory}/my.properties</outputFile>
</configuration>

For those looking for a fuller example (it took me a bit of fiddling to get this working as I didn't understand how naming of properties tags affects ability to retrieve them elsewhere in the pom file), my pom looks as follows:

<dependencies>
     <dependency>
      ...
     </dependency>
</dependencies>

<properties>
    <app.env>${app.env}</app.env>
    <app.port>${app.port}</app.port>
    <app.domain>${app.domain}</app.domain>
</properties>

                    <goals>
                        <goal>write-project-properties</goal>
                    </goals>
                    <configuration>
                        <outputFile>${project.build.testOutputDirectory}/my.properties</outputFile>
                    </configuration>
                </execution>
            </executions>
        </plugin>

    </plugins>
</build>

And on the command line:

mvn clean test -Dapp.env=LOCAL -Dapp.domain=localhost -Dapp.port=9901

So these properties can be accessed from the Java code:

 java.io.InputStream inputStream = Thread.currentThread().getContextClassLoader().getResourceAsStream("my.properties");
 java.util.Properties properties = new Properties();
 properties.load(inputStream);
 appPort = properties.getProperty("app.port");
 appDomain = properties.getProperty("app.domain");

In the java console, hit Ctrl-Break. It will list all threads plus some information about the heap. This won't give you access to the objects of course. But it can be very helpful for debugging anyway.

you can do that using boost::assign.

vector<int> values;  
values += 1,2,3,4,5,6,7,8,9;

All of these answers require grep to generate the entire matching lines, then pipe it to another program. If your lines are very long, it might be more efficient to use just sed to output the line numbers:

These answers are pretty good, but as far as getting the items to order properly, you'd be better off looking at this article http://dataeducation.com/dr-output-or-how-i-learned-to-stop-worrying-and-love-the-merge

Here's an example of his query.

WITH paths AS ( 
    SELECT 
        EmployeeID, 
        CONVERT(VARCHAR(900), CONCAT('.', EmployeeID, '.')) AS FullPath 
    FROM EmployeeHierarchyWide 
    WHERE ManagerID IS NULL

    UNION ALL

    SELECT 
        ehw.EmployeeID, 
        CONVERT(VARCHAR(900), CONCAT(p.FullPath, ehw.EmployeeID, '.')) AS FullPath 
    FROM paths AS p 
        JOIN EmployeeHierarchyWide AS ehw ON ehw.ManagerID = p.EmployeeID 
) 
SELECT * FROM paths order by FullPath

I think the problem is that when you're trying to compile testpoint.c, it includes point.h but it doesn't know about point.c. Since point.c has the definition for create, not having point.c will cause the compilation to fail.

I'm not familiar with MinGW, but you need to tell the compiler to look for point.c. For example with gcc you might do this:

gcc point.c testpoint.c

As others have pointed out, you also need to remove one of your main functions, since you can only have one.

If you want to fetch + merge, run

git pull

if you want simply to fetch :

In c and C++ there is no data type called BOOLEAN Thats why it uses 1 and 0 as true false value. and in JAVA 1 and 0 are count as an INTEGER type so it produces error in java. And java have its own boolean values true and false with boolean data type.

happy programming..

    return "\x1b[38;2;" + _r + ";" + _g + ";" + _b + "m" + _text + "\x1b[0m";
};

This code help set foreground color: \x1b[38;2;R;G;Bm

Not directly C#, but the formula is: n = floor(log10(x)+1)

Since you are loading in the spans via ajax you will have to attach delegate handlers to the events to catch them as they bubble up.

$(document).on('click','span',function(e){
    console.log(e.target.id)
})

you will want to attach the event to the closest static member you can to increase efficiency.

$('#main_div').on('click','span',function(e){
    console.log(e.target.id)
})

is better than binding to the document for instance.

Use flatMap. If a value is present, flatMap returns a sequential Stream containing only that value, otherwise returns an empty Stream. So there is no need to use ifPresent() . Example:

list.stream().map(data -> data.getSomeValue).map(this::getOptinalValue).flatMap(Optional::stream).collect(Collectors.toList());

In my case it was because of an invisible character at the beginning of the path:

There is no support for array in sql server but there are several ways by which you can pass collection to a stored proc .

1. By using datatable
2. By using XML.Try converting your collection in an xml format and then pass it as an input to a stored procedure

The below link may help you

passing collection to a stored procedure

I think below way is the simplest way to achieving same :

    $user = User::where('email', '=', $request->input('email'))->first();
    if ($user) {
       // user doesn't exist!
    }

Instead of rand(), use newid(), which is recalculated for each row in the result. The usual way is to use the modulo of the checksum. Note that checksum(newid()) can produce -2,147,483,648 and cause integer overflow on abs(), so we need to use modulo on the checksum return value before converting it to absolute value.

UPDATE CattleProds
SET    SheepTherapy = abs(checksum(NewId()) % 10000)
WHERE  SheepTherapy IS NULL

This generates a random number between 0 and 9999.

Question:

What is the most efficient way to create HTML elements using jQuery?

Answer:

Since it's about jQuery then I think it's better to use this (clean) approach (you are using)

$('<div/>', {
    'id':'myDiv',
    'class':'myClass',
    'text':'Text Only',
}).on('click', function(){
    alert(this.id); // myDiv
}).appendTo('body');

DEMO.

This way, you can even use event handlers for the specific element like

$('<div/>', {
    'id':'myDiv',
    'class':'myClass',
    'style':'cursor:pointer;font-weight:bold;',
    'html':'<span>For HTML</span>',
    'click':function(){ alert(this.id) },
    'mouseenter':function(){ $(this).css('color', 'red'); },
    'mouseleave':function(){ $(this).css('color', 'black'); }
}).appendTo('body');

DEMO.

But when you are dealing with lots of dynamic elements, you should avoid adding event handlers in particular element, instead, you should use a delegated event handler, like

$(document).on('click', '.myClass', function(){
    alert(this.innerHTML);
});

var i=1;
for(;i<=200;i++){
    $('<div/>', {
        'class':'myClass',
        'html':'<span>Element'+i+'</span>'
    }).appendTo('body');
}

DEMO.

So, if you create and append hundreds of elements with same class, i.e. (myClass) then less memory will be consumed for event handling, because only one handler will be there to do the job for all dynamically inserted elements.

Update : Since we can use following approach to create a dynamic element

$('<input/>', {
    'type': 'Text',
    'value':'Some Text',
    'size': '30'
}).appendTo("body");

But the size attribute can't be set using this approach using jQuery-1.8.0 or later and here is an old bug report, look at this example using jQuery-1.7.2 which shows that size attribute is set to 30 using above example but using same approach we can't set size attribute using jQuery-1.8.3, here is a non-working fiddle. So, to set the size attribute, we can use following approach

$('<input/>', {
    'type': 'Text',
    'value':'Some Text',
    attr: { size: "30" }
}).appendTo("body");

Or this one

$('<input/>', {
    'type': 'Text',
    'value':'Some Text',
    prop: { size: "30" }
}).appendTo("body");

We can pass attr/prop as a child object but it works in jQuery-1.8.0 and later versions check this example but it won't work in jQuery-1.7.2 or earlier (not tested in all earlier versions).

BTW, taken from jQuery bug report

There are several solutions. The first is to not use it at all, since it doesn't save you any space and this improves the clarity of the code:

They advised to use following approach (works in earlier ones as well, tested in 1.6.4)

$('<input/>')
.attr( { type:'text', size:50, autofocus:1 } )
.val("Some text").appendTo("body");

So, it is better to use this approach, IMO. This update is made after I read/found this answer and in this answer shows that if you use 'Size'(capital S) instead of 'size' then it will just work fine, even in version-2.0.2

$('<input>', {
    'type' : 'text',
    'Size' : '50', // size won't work
    'autofocus' : 'true'
}).appendTo('body');

Also read about prop, because there is a difference, Attributes vs. Properties, it varies through versions.

You can do it with something like this, so if no arguments are specified it will continue anyway:

public static void main(String[] args) {
    try {
        String one = args[0];
        String two = args[1];
    }
    catch (ArrayIndexOutOfBoundsException e){
        System.out.println("ArrayIndexOutOfBoundsException caught");
    }
    finally {

    }
}

And then launch the application:

java -jar myapp.jar arg1 arg2

use the android:background attribute in your xml. Easiest way if you want to apply it to a whole activity is to put it in the root of your layout. So if you have a RelativeLayout as the start of your xml, put it in here:

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:id="@+id/rootRL"
    android:orientation="vertical" 
    android:layout_width="fill_parent"
    android:layout_height="fill_parent" 
    android:background="@drawable/background">
</RelativeLayout>

With React Functional way

import React, { useEffect } from "react";
import ReactDOM from "react-dom";
import Button from "@material-ui/core/Button";

const App = () => {
  const saySomething = (something) => {
    console.log(something);
  };
  useEffect(() => {
    saySomething("from useEffect");
  });
  const handleClick = (e) => {
    saySomething("element clicked");
  };
  return (
    <Button variant="contained" color="primary" onClick={handleClick}>
      Hello World
    </Button>
  );
};

ReactDOM.render(<App />, document.querySelector("#app"));

The best tool for doing layouts using grid, IMHO, is graph paper and a pencil. I know you're asking for some type of program, but it really does work. I've been doing Tk programming for a couple of decades so layout comes quite easily for me, yet I still break out graph paper when I have a complex GUI.

Another thing to think about is this: The real power of Tkinter geometry managers comes from using them together*. If you set out to use only grid, or only pack, you're doing it wrong. Instead, design your GUI on paper first, then look for patterns that are best solved by one or the other. Pack is the right choice for certain types of layouts, and grid is the right choice for others. For a very small set of problems, place is the right choice. Don't limit your thinking to using only one of the geometry managers.

* The only caveat to using both geometry managers is that you should only use one per container (a container can be any widget, but typically it will be a frame).

Use the pickle module to save it to disk and load later on.

This is common problem for asterisk and this works for me

sudo su

sudo su
/etc/init.d/asterisk start 
asterisk -rvvv

It's already answered here -> Is my virtual environment (python) causing my PYTHONPATH to break?

UNIX/LINUX

Add "export PYTHONPATH=/usr/local/lib/python2.0" this to ~/.bashrc file and source it by typing "source ~/.bashrc" OR ". ~/.bashrc".

WINDOWS XP

1) Go to the Control panel 2) Double click System 3) Go to the Advanced tab 4) Click on Environment Variables

In the System Variables window, check if you have a variable named PYTHONPATH. If you have one already, check that it points to the right directories. If you don't have one already, click the New button and create it.

PYTHON CODE

Alternatively, you can also do below your code:-

import sys
sys.path.append("/home/me/mypy") 

You can use the parseInt() function to convert the string to a number, e.g:

parseInt($('#elem').css('top'));

Update: (as suggested by Ben): You should give the radix too:

parseInt($('#elem').css('top'), 10);

Forces it to be parsed as a decimal number, otherwise strings beginning with '0' might be parsed as an octal number (might depend on the browser used).

I have same problem but CleanUp eclipse option doesn't work for me.

1) install TortoiseSVN
2) Go to windows explorer and right click on your project directory
3 Choice CleanUp option (by checking break lock option)

It's works.

Edit: Just as a note, if you just need a quick and easy way of finding the distance between two points, I strongly recommend using the approach described in Kurt's answer below instead of re-implementing Haversine -- see his post for rationale.

This answer focuses just on answering the specific bug OP ran into.

It's because in Python, all the trig functions use radians, not degrees.

You can either convert the numbers manually to radians, or use the radians function from the math module:

from math import sin, cos, sqrt, atan2, radians

# approximate radius of earth in km
R = 6373.0

lat1 = radians(52.2296756)
lon1 = radians(21.0122287)
lat2 = radians(52.406374)
lon2 = radians(16.9251681)

dlon = lon2 - lon1
dlat = lat2 - lat1

a = sin(dlat / 2)**2 + cos(lat1) * cos(lat2) * sin(dlon / 2)**2
c = 2 * atan2(sqrt(a), sqrt(1 - a))

distance = R * c

print("Result:", distance)
print("Should be:", 278.546, "km")

The distance is now returning the correct value of 278.545589351 km.

You can do it in a few lines like this:

BOOL valid;
NSCharacterSet *alphaNums = [NSCharacterSet decimalDigitCharacterSet];
NSCharacterSet *inStringSet = [NSCharacterSet characterSetWithCharactersInString:myInputField.text];
valid = [alphaNums isSupersetOfSet:inStringSet];    
if (!valid) // Not numeric

-- this is for validating input is numeric chars only. Look at the documentation for NSCharacterSet for the other options. You can use characterSetWithCharactersInString to specify any set of valid input characters.

Here is a simple dropdown checklist:

var checkList = document.getElementById('list1');
checkList.getElementsByClassName('anchor')[0].onclick = function(evt) {
  if (checkList.classList.contains('visible'))
    checkList.classList.remove('visible');
  else
    checkList.classList.add('visible');
}

.dropdown-check-list {
  display: inline-block;
}

I found this while googling the issue with android licences when installing Flutter.

For Linux, update Your ~/.bashrc (or other shell config) file by adding this line at the end:

JAVA_HOME=/usr/local/android-studio/jre

Note: I installed Android studio by following the official installation guide for Linux (link).

For Windows, use the android studio's path to the jre directory and update the environment variable with the right value.

Then, run flutter doctor --android-licenses and press y to review the licences which are not accepted. Press y for each of the licences. It will ask Accept? (y/N): at the end of the license file. After You accept all unaccepted licences, You should see:

All SDK package licenses accepted

If you're on Windows:

HANDLE h;
CHAR_INFO v3;
COORD v4;
SMALL_RECT v5;
CONSOLE_SCREEN_BUFFER_INFO v6;
if ((h = (HANDLE)GetStdHandle(0xFFFFFFF5), (unsigned int)GetConsoleScreenBufferInfo(h, &v6)))
{
    v5.Right = v6.dwSize.X;
    v5.Bottom = v6.dwSize.Y;
    v3.Char.UnicodeChar = 32;
    v4.Y = -v6.dwSize.Y;
    v3.Attributes = v6.wAttributes;
    v4.X = 0;
    *(DWORD *)&v5.Left = 0;
    ScrollConsoleScreenBufferW(h, &v5, 0, v4, &v3);
    v6.dwCursorPosition = { 0 };
    HANDLE v1 = GetStdHandle(0xFFFFFFF5);
    SetConsoleCursorPosition(v1, v6.dwCursorPosition);
}

This is what the system("cls"); does without having to create a process to do it.

Another, more functional, way:

my_map = { 'a': 1, 'b':2 }
dict(map(reversed, my_map.items()))

This should do it (where df is your dataframe)

df$JoiningDate <- as.Date(df$JoiningDate , format = "%m/%d/%y")

df[order(df$JoiningDate ),]

This is a simple function (Bash shell) which lets you create a directory if it doesn't exist.

#----------------------------------
# Create a directory if it doesn't exist
#------------------------------------
createDirectory() {
    if [ ! -d $1 ]
        then
        mkdir -p $1
    fi
}

You can call the above function as:

createDirectory /tmp/fooDir/BarDir

The above creates fooDir and BarDir if they don't exist. Note the "-p" option in the mkdir command which creates directories recursively.

When you declare:

int column, row, index = 0;

Only index is set to zero.

However you can do the following:

int column, row, index;
column = index = row = 0;

But personally I prefer the following which has been pointed out.
It's a more readable form in my view.

int column = 0, row = 0, index = 0;

or

int column = 0;
int row = 0;
int index = 0;

Your query should have date as

select * from table between `lowerdate` and `upperdate`

try

SELECT * FROM `objects` 
WHERE  (date_field BETWEEN '2010-01-30 14:15:55' AND '2010-09-29 10:15:55')

Others have given pretty good answers as far as "standards" go, but I just wanted to add this... Is it possible that "User" (or "Users") is not actually a full description of the data held in the table? Not that you should get too crazy with table names and specificity, but perhaps something like "Widget_Users" (where "Widget" is the name of your application or website) would be more appropriate.

there are many causes such as

• The network link between server and client may be temporarily going down.
• running out of system resources.
• sending malformed data.

To examine the problem in detail, you can use Wireshark.

or you can just re-request or re-connect again.

The problem is with your curl options – the RCurl package doesn't seem to use internet2.dll. You need to specify the port separately, and will probably need to give your user login details as network credentials, e.g.,

opts <- list(
  proxy         = "999.999.999.999", 
  proxyusername = "mydomain\\myusername", 
  proxypassword = "mypassword", 
  proxyport     = 8080
)
getURL("http://stackoverflow.com", .opts = opts)

Remember to escape any backslashes in your password. You may also need to wrap the URL in a call to curlEscape.

For array of objects:

var array= JSON.parse('@Newtonsoft.Json.JsonConvert.SerializeObject(numbers)'.replace(/"/g, "\""));

For array of int:

 var array= JSON.parse('@Newtonsoft.Json.JsonConvert.SerializeObject(numbers)');

Like the OP, I was looking for a Windows folder diff tool, in particular one that could handle very large trees (100s of Gigabytes of data). Thanks Lieven Keersmaekers for the pointer to BeyondCompare, which I found to be VERY fast (roughly 10-100 times faster) than my previous old school tool windiff.

BTW, BeyondCompare does have a command line mode in addition to the GUI.

This happens when the pointer passed to free() is not valid or has been modified somehow. I don't really know the details here. The bottom line is that the pointer passed to free() must be the same as returned by malloc(), realloc() and their friends. It's not always easy to spot what the problem is for a novice in their own code or even deeper in a library. In my case, it was a simple case of an undefined (uninitialized) pointer related to branching.

The free() function frees the memory space pointed to by ptr, which must have been returned by a previous call to malloc(), calloc() or realloc(). Otherwise, or if free(ptr) has already been called before, undefined behavior occurs. If ptr is NULL, no operation is performed. GNU 2012-05-10 MALLOC(3)

char *words; // setting this to NULL would have prevented the issue

if (condition) {
    words = malloc( 512 );

    /* calling free sometime later works here */

    free(words)
} else {

    /* do not allocate words in this branch */
}

/* free(words);  -- error here --
*** glibc detected *** ./bin: munmap_chunk(): invalid pointer: 0xb________ ***/

There are many similar questions here about the related free() and rellocate() functions. Some notable answers providing more details:

*** glibc detected *** free(): invalid next size (normal): 0x0a03c978 ***
*** glibc detected *** sendip: free(): invalid next size (normal): 0x09da25e8 ***
glibc detected, realloc(): invalid pointer

IMHO running everything in a debugger (Valgrind) is not the best option because errors like this are often caused by inept or novice programmers. It's more productive to figure out the issue manually and learn how to avoid it in the future.

Solution:

INSERT INTO `table` (`value1`, `value2`) 
SELECT 'stuff for value1', 'stuff for value2' FROM DUAL 
WHERE NOT EXISTS (SELECT * FROM `table` 
      WHERE `value1`='stuff for value1' AND `value2`='stuff for value2' LIMIT 1) 

Explanation:

The innermost query

SELECT * FROM `table` 
      WHERE `value1`='stuff for value1' AND `value2`='stuff for value2' LIMIT 1

used as the WHERE NOT EXISTS-condition detects if there already exists a row with the data to be inserted. After one row of this kind is found, the query may stop, hence the LIMIT 1 (micro-optimization, may be omitted).

The intermediate query

SELECT 'stuff for value1', 'stuff for value2' FROM DUAL

represents the values to be inserted. DUAL refers to a special one row, one column table present by default in all Oracle databases (see https://en.wikipedia.org/wiki/DUAL_table). On a MySQL-Server version 5.7.26 I got a valid query when omitting FROM DUAL, but older versions (like 5.5.60) seem to require the FROM information. By using WHERE NOT EXISTS the intermediate query returns an empty result set if the innermost query found matching data.

The outer query

INSERT INTO `table` (`value1`, `value2`) 

inserts the data, if any is returned by the intermediate query.

• in a Windows Forms app, you could tap into the Application.Idle event and check to see whether you've reached the time in the day to call your method. This method is only called when your app isn't busy with other stuff. A quick check to see if your target time has been reached shouldn't put too much stress on your app, I think...
• in a ASP.NET web app, there are methods to "simulate" sending out scheduled events - check out this CodeProject article
• and of course, you can also just simply "roll your own" in any .NET app - check out this CodeProject article for a sample implementation

Update #2: if you want to check every 60 minutes, you could create a timer that wakes up every 60 minutes and if the time is up, it calls the method.

Something like this:

using System.Timers;

const double interval60Minutes = 60 * 60 * 1000; // milliseconds to one hour

Timer checkForTime = new Timer(interval60Minutes);
checkForTime.Elapsed += new ElapsedEventHandler(checkForTime_Elapsed);
checkForTime.Enabled = true;

and then in your event handler:

void checkForTime_Elapsed(object sender, ElapsedEventArgs e)
{
    if (timeIsReady())
    {
       SendEmail();
    }
}

After inspecting closely, looks like both of you are using closure.

In your friends case, i is accessed inside anonymous function 1 and i2 is accessed in anonymous function 2 where the console.log is present.

In your case you are accessing i2 inside anonymous function where console.log is present. Add a debugger; statement before console.log and in chrome developer tools under "Scope variables" it will tell under what scope the variable is.

Little sum up for searching by row:

This can be useful if you don't know the column values ??or if columns have non-numeric values

if u want get index number as integer u can also do:

item = df[4:5].index.item()
print(item)
4

it also works in numpy / list:

numpy = df[4:7].index.to_numpy()[0]
lista = df[4:7].index.to_list()[0]

in [x] u pick number in range [4:7], for example if u want 6:

numpy = df[4:7].index.to_numpy()[2]
print(numpy)
6

for DataFrame:

df[4:7]

    A          B
4   5   0.894525
5   6   0.978174
6   7   0.859449

or:

df[(df.index>=4) & (df.index<7)]

    A          B
4   5   0.894525
5   6   0.978174
6   7   0.859449   

yield is more flexible than map(), see example below

val aList = List( 1,2,3,4,5 )

val res3 = for ( al <- aList if al > 3 ) yield al + 1 
val res4 = aList.map( _+ 1 > 3 ) 

println( res3 )
println( res4 )

yield will print result like: List(5, 6), which is good

while map() will return result like: List(false, false, true, true, true), which probably is not what you intend.

You can create a function that takes a variable number of arguments:

function setAttributes(elem /* attribute, value pairs go here */) {
    for (var i = 1; i < arguments.length; i+=2) {
        elem.setAttribute(arguments[i], arguments[i+1]);
    }
}

setAttributes(elem, 
    "src", "http://example.com/something.jpeg",
    "height", "100%",
    "width", "100%");

Or, you pass the attribute/value pairs in on an object:

 function setAttributes(elem, obj) {
     for (var prop in obj) {
         if (obj.hasOwnProperty(prop)) {
             elem[prop] = obj[prop];
         }
     }
 }

setAttributes(elem, {
    src: "http://example.com/something.jpeg",
    height: "100%",
    width: "100%"
});

You could also make your own chainable object wrapper/method:

function $$(elem) {
    return(new $$.init(elem));
}

$$.init = function(elem) {
    if (typeof elem === "string") {
        elem = document.getElementById(elem);
    }
    this.elem = elem;
}

$$.init.prototype = {
    set: function(prop, value) {
        this.elem[prop] = value;
        return(this);
    }
};

$$(elem).set("src", "http://example.com/something.jpeg").set("height", "100%").set("width", "100%");

Express version:

"dependencies": {
    "body-parser": "^1.19.0",
    "express": "^4.17.1"
  }

Optional parameter are very much handy, you can declare and use them easily using express:

app.get('/api/v1/tours/:cId/:pId/:batchNo?', (req, res)=>{
    console.log("category Id: "+req.params.cId);
    console.log("product ID: "+req.params.pId);
    if (req.params.batchNo){
        console.log("Batch No: "+req.params.batchNo);
    }
});

In the above code batchNo is optional. Express will count it optional because after in URL construction, I gave a '?' symbol after batchNo '/:batchNo?'

Now I can call with only categoryId and productId or with all three-parameter.

http://127.0.0.1:3000/api/v1/tours/5/10
//or
http://127.0.0.1:3000/api/v1/tours/5/10/8987

Basically , Data in a Date column in Oracle can be stored in any user defined format or kept as default. It all depends on NLS parameter.

Current format can be seen by : SELECT SYSDATE FROM DUAL;

If you try to insert a record and insert statement is NOT in THIS format then it will give : ORA-01843 : not a valid month error. So first change the database date format before insert statements ( I am assuming you have bulk load of insert statements) and then execute insert script.

Format can be changed by : ALTER SESSION SET nls_date_format = 'mm/dd/yyyy hh24:mi:ss';

Also You can Change NLS settings from SQL Developer GUI , (Tools > preference> database > NLS)

Ref: http://oracle.ittoolbox.com/groups/technical-functional/oracle-sql-l/how-to-view-current-date-format-1992815

Use character classes:

^[[:alnum:]]*$

Try this:

Since you are fetching based on a single column value you can simplify your query likewise:

$reservations = Reservation::whereBetween('reservation_from', array($from, $to))->get();

Retrieve based on condition: laravel docs

Hope this helped.

yep - you can even nest the try catch statements as:

BEGIN TRY
SET @myFixDte = CONVERT(datetime, @myFixDteStr,101)
END TRY
BEGIN CATCH
    BEGIN TRY
        SET @myFixDte = CONVERT(datetime, @myFixDteStr,103)
END TRY
BEGIN CATCH
    BEGIN TRY
        SET @myFixDte = CONVERT(datetime, @myFixDteStr,104)
    END TRY
    BEGIN CATCH
        SET @myFixDte = CONVERT(datetime, @myFixDteStr,105)
    END CATCH
END CATCH END CATCH

Two ways, one which avoids the tag completely, the other using a naughty but nice utility method.
The problem is pre-genericised Collections...
I believe the rule of thumb is: "cast objects one thing at a time" - what this means when trying to use raw classes in a genericised world is that because you don't know what is in this Map<?, ?> (and indeed the JVM might even find that it isn't even a Map!), it obvious when you think about it that you can't cast it. If you had a Map<String, ?> map2 then HashSet<String> keys = (HashSet<String>)map2.keySet() does not give you a warning, despite this being an "act of faith" for the compiler (because it might turn out to be a TreeSet)... but it is only a single act of faith.

PS to the objection that iterating as in my first way "is boring" and "takes time", the answer is "no pain no gain": a genericised collection is guaranteed to contain Map.Entry<String, String>s, and nothing else. You have to pay for this guarantee. When using generics systematically this payment, beautifully, takes the form of coding compliance, not machine time!
One school of thought might say that you should set Eclipse's settings to make such unchecked casts errors, rather than warnings. In that case you would have to use my first way.

package scratchpad;

import java.util.HashMap;
import java.util.Iterator;
import java.util.Map;
import java.util.Vector;

public class YellowMouse {

    // First way

    Map<String, String> getHashMapStudiouslyAvoidingSuppressTag(HttpSession session) {
      Map<?, ?> theHash = (Map<?, ?>)session.getAttribute("attributeKey");

      Map<String, String> yellowMouse = new HashMap<String, String>();
      for( Map.Entry<?, ?> entry : theHash.entrySet() ){
        yellowMouse.put( (String)entry.getKey(), (String)entry.getValue() );
      }

      return yellowMouse;
    }


    // Second way

    Map<String, String> getHashMapUsingNaughtyButNiceUtilityMethod(HttpSession session) {
      return uncheckedCast( session.getAttribute("attributeKey") );
    }


    // NB this is a utility method which should be kept in your utility library. If you do that it will
    // be the *only* time in your entire life that you will have to use this particular tag!!

    @SuppressWarnings({ "unchecked" })
    public static synchronized <T> T uncheckedCast(Object obj) {
        return (T) obj;
    }


}

Using map:

var values = $("input[id='task']")
              .map(function(){return $(this).val();}).get();

If you change or remove the id (which should be unique), you may also use the selector $("input[name='task\\[\\]']")

Here are a couple basic examples to get started quick and dirty.

One item variable

Set variable:

SET(INSTALL_ETC_DIR "etc")

Use variable:

SET(INSTALL_ETC_CROND_DIR "${INSTALL_ETC_DIR}/cron.d")

Multi-item variable (ie. list)

Set variable:

SET(PROGRAM_SRCS
        program.c
        program_utils.c
        a_lib.c
        b_lib.c
        config.c
        )

Use variable:

add_executable(program "${PROGRAM_SRCS}")

You can't have a link to SCSS File in your HTML page.You have to compile it down to CSS First. No there are lots of video tutorials you might want to check out. Lynda provides great video tutorials on SASS. there are also free screencasts you can google...

For official documentation visit this site http://sass-lang.com/documentation/file.SASS_REFERENCE.html And why have you chosen notepad to write Sass?? you can easily download some free text editors for better code handling.

In ASP.NET Core 2.0 you can add Route attribute to the controller:

[Route("api/[controller]/[action]")]
public class SomeController : Controller
{
    public SomeValue GetItems(CustomParam parameter) { ... }

    public SomeValue GetChildItems(CustomParam parameter, SomeObject parent) { ... }
}

foo.ToArray().Aggregate((a, b) => (a + "," + b)).ToString()

or

string.Concat(foo.ToArray().Select(a => a += ",").ToArray())

Updating, as this is extremely old. You should, of course, use string.Join now. It didn't exist as an option at the time of writing.

99.9% likely that you have corrupted memory (over- or under-flowed a buffer, wrote to a pointer after it was freed, called free twice on the same pointer, etc.)

Run your code under Valgrind to see where your program did something incorrect.

If you're using WordPress, there is now a filter hook to resolve this:

remove_filter('template_redirect', 'redirect_canonical'); 

(Put this in your theme's functions.php)

This tells WordPress to not redirect index.php back to the root page, but to sit where it is. That way, index.html can be assigned to be the default page in .htaccess and can work alongside index.php.

Download the appropriate APR based tomcat native library for your operating system so that Apache tomcat server can take some advantage of the feature of your OS which is not included by default in tomcat. For windows it will be a .dll file.

I too got the warning while starting the server and you don't have to worry about this if you are testing or developing. This is meant to be on production purposes. After putting the tcnative-1.dll file inside the bin folder of Apache Tomcat 7 following are the output in the stderr file,

I should this On Windows, environment variable expansion is %BUILD_NUMBER%

df --output=avail -B 1 "$PWD" |tail -n 1

you get size in bytes this way.

I know this is an old post, but I ran into this same issue with my VMs. Log into the VM and go to Control Panel > System and Security > Windows Firewall > Allowed Apps. Then check all of the boxes next to "File and Printer Sharing" to enable file sharing. This should allow you to ping the VM. The screenshot below is from a 2016 Windows Server but the same method will work on older ones.

The properties center, bounds and frame are interlocked: changing one will update the others, so use them however you want. For example, instead of modifying the x/y params of frame to recenter a view, just update the center property.

Add the item first and then serialize:

$.ajax({
    type: 'POST',
    url: this.action,
    data: $.extend($(this), {'NonFormValue': NonFormValue}).serialize()
});

The linux/unix "find" command.

It may be a bit pedantic / redundant with its numeric casting, but here's a safe function to calculate percentage of a given number:

function getPerc(num, percent) {
    return Number(num) - ((Number(percent) / 100) * Number(num));
}

// Usage: getPerc(10000, 25);

You can do that in this way:

ORDER BY `products`.`product_category_id` DESC ,`naam` ASC

Have a look at ORDER BY Optimization

You cannot resize an array in java.

Once the size of array is declared, it remains fixed.

Instead you can use ArrayList that has dynamic size, meaning you don't need to worry about its size. If your array list is not big enough to accommodate new values then it will be resized automatically.

ArrayList<String> ar = new ArrayList<String>();
String s1 ="Test1";
String s2 ="Test2";
String s3 ="Test3";
ar.add(s1);
ar.add(s2);
ar.add(s3);

String s4 ="Test4";
ar.add(s4);

Disabled is a Boolean Attribute of the select element as stated by WHATWG, that means the RIGHT WAY TO DISABLE with jQuery would be

jQuery("#selectId").attr('disabled',true);

This would make this HTML

<select id="selectId" name="gender" disabled="disabled">
    <option value="-1">--Select a Gender--</option>
    <option value="0">Male</option>
    <option value="1">Female</option>
</select>

This works for both XHTML and HTML (W3School reference)

Yet it also can be done using it as property

jQuery("#selectId").prop('disabled', 'disabled');

getting

<select id="selectId" name="gender" disabled>

Which only works for HTML and not XTML

NOTE: A disabled element will not be submitted with the form as answered in this question: The disabled form element is not submitted

NOTE2: A disabled element may be greyed out.

NOTE3:

A form control that is disabled must prevent any click events that are queued on the user interaction task source from being dispatched on the element.

TL;DR

<script>
    var update_pizza = function () {
        if ($("#pizza").is(":checked")) {
            $('#pizza_kind').attr('disabled', false);
        } else {
            $('#pizza_kind').attr('disabled', true);
        }
    };
    $(update_pizza);
    $("#pizza").change(update_pizza);
</script>

You could try writing the XDocument to an XmlWriter piped to an XmlReader for an XmlDocument.

If I understand the concepts properly, a direct conversion is not possible (the internal structure is different / simplified with XDocument). But then, I might be wrong...

You should really use the Literal ASP.NET control for that.

You can easily customize the android Navigation drawer once you know how its implemented. here is a nice tutorial where you can set it up.

This will be the structure of your mainXML:

<android.support.v4.widget.DrawerLayout
    xmlns:android="http://schemas.android.com/apk/res/android"
    android:id="@+id/drawer_layout"
    android:layout_width="match_parent"
    android:layout_height="match_parent">

    <!-- Framelayout to display Fragments -->
    <FrameLayout
        android:id="@+id/frame_container"
        android:layout_width="match_parent"
        android:layout_height="match_parent" />

    <!-- Listview to display slider menu -->
    <ListView
        android:id="@+id/list_slidermenu"
        android:layout_width="240dp"
        android:layout_height="match_parent"
        android:layout_gravity="right"
        android:choiceMode="singleChoice"
        android:divider="@color/list_divider"
        android:dividerHeight="1dp"        
        android:listSelector="@drawable/list_selector"
        android:background="@color/list_background"/>
</android.support.v4.widget.DrawerLayout>

You can customize this listview to your liking by adding the header. And radiobuttons.

I didn't need to set up remote debugging in order to get this working, I used Maven.

1. Ensure you have the Maven plugin installed into Eclipse.
2. Click Run > Run Configurations > Maven Build > new launch configuration:
   • Base directory: browse to the root of your project
   • Goals: spring-boot::run.
3. Click Apply then click Run.

NB. If your IDE has problems finding your project's source code when doing line-by-line debugging, take a look at this SO answer to find out how to manually attach your source code to the debug application.

Hope this helps someone!

This isn't possible due to security reasons. At least not on modern browsers. This is because any code getting access to the path of the file can be considered dangerous and a security risk. Either you'll end up with an undefined value, an empty string or an error will be thrown.

When a file form is submitted, the browser buffers the file temporarily into an upload directory and only the temporary file name of that file and basename of that file is submitted.

I'm running version 1.0.2 of flask right now. The above file structures did not work for me, but I found one that did, which are as follows:

     app_folder/ flask_app.py/ static/ style.css/ templates/
     index.html

(Please note that 'static' and 'templates' are folders, which should be named exactly the same thing.)

To check what version of flask you are running, you should open Python in terminal and type the following accordingly:

import flask

flask --version

Noticing that user 42-'s perfect approach {
* "do while" = "repeat until not"
* The code equivalence:

do while (condition) # in other language
..statements..
endo

repeat{ # in R
  ..statements..
  if(! condition){ break } # Negation is crucial here!
}

} did not receive enough attention from the others, I'll emphasize and bring forward his approach via a concrete example. If one does not negate the condition in do-while (via ! or by taking negation), then distorted situations (1. value persistence 2. infinite loop) exist depending on the course of the code.

In Gauss:

proc(0)=printvalues(y);
DO WHILE y < 5;    
y+1;
 y=y+1;
ENDO;
ENDP;
printvalues(0); @ run selected code via F4 to get the following @
       1.0000000 
       2.0000000 
       3.0000000 
       4.0000000 
       5.0000000 

In R:

printvalues <- function(y) {
repeat {
 y=y+1;
print(y)
if (! (y < 5) ) {break}   # Negation is crucial here!
}
}
printvalues(0)
# [1] 1
# [1] 2
# [1] 3
# [1] 4
# [1] 5

I still insist that without the negation of the condition in do-while, Salcedo's answer is wrong. One can check this via removing negation symbol in the above code.

warning! this does not work with links.

var variable = 'variable', another = 'another';

['I would', 'like to'].join(' ') + ' a js ' + variable + ' together with ' + another + ' to create ' + [another, ...[variable].concat('name')].join(' ').concat('...');

You are passing wrong mode to you view. Your view is looking for @model IEnumerable<Standings.Models.Teams> and you are passing var model = tm.Name.ToList(); name list. You have to pass list of Teams.

You have to pass following model

var model = new List<Teams>();

model.Add(new Teams { Name =  new List<string>(){"Sky","ABC"}});
model.Add(new Teams { Name =  new List<string>(){"John","XYZ"} });
return View(model);

For the 24-hour time, you need to use HH24 instead of HH.

For the 12-hour time, the AM/PM indicator is written as A.M. (if you want periods in the result) or AM (if you don't). For example:

SELECT invoice_date,
       TO_CHAR(invoice_date, 'DD-MM-YYYY HH24:MI:SS') "Date 24Hr",
       TO_CHAR(invoice_date, 'DD-MM-YYYY HH:MI:SS AM') "Date 12Hr"
  FROM invoices
;

For more information on the format models you can use with TO_CHAR on a date, see http://docs.oracle.com/cd/E16655_01/server.121/e17750/ch4datetime.htm#NLSPG004.

If you want to get the image from gallery or capture the image and set it to the imageview in portrait mode then following code will help you..

If targetSdkVersion is higher than 24, then FileProvider is used to grant access.

Create an xml file(Path: res\xml) provider_paths.xml

<?xml version="1.0" encoding="utf-8"?>
<paths xmlns:android="http://schemas.android.com/apk/res/android">
    <external-path name="external_files" path="."/>
</paths>

Add a Provider in AndroidManifest.xml

<provider
    android:name="android.support.v4.content.FileProvider"
    android:authorities="${applicationId}.provider"
    android:exported="false"
    android:grantUriPermissions="true">
    <meta-data
        android:name="android.support.FILE_PROVIDER_PATHS"
        android:resource="@xml/provider_paths"/>
</provider>

and replace

return Uri.fromFile(getOutputMediaFile(type));

To

               return FileProvider.getUriForFile(this,  BuildConfig.APPLICATION_ID + ".provider", getOutputMediaFile(type));
