use the click event for best compatibility with MSIE

$(document).ready(function() {
    $("input[type=checkbox]").click(function() {
        alert("state changed");
    });
});

Check this code:

<!-- script to check whether checkbox checked or not using prop function -->
<script>
$('#change_password').click(function(){
    if($(this).prop("checked") == true){ //can also use $(this).prop("checked") which will return a boolean.
        alert("checked");
    }
    else if($(this).prop("checked") == false){
        alert("Checkbox is unchecked.");
    }
});
</script>

In CMD, write:

javac -Xlint:unchecked MyGui2.java

it will display the list of unchecked or unsafe operations.

A warning is just that. A warning. Sometimes warnings are irrelevant, sometimes they're not. They're used to call your attention to something that the compiler thinks could be a problem, but may not be.

In the case of casts, it's always going to give a warning in this case. If you are absolutely certain that a particular cast will be safe, then you should consider adding an annotation like this (I'm not sure of the syntax) just before the line:

@SuppressWarnings (value="unchecked")

Simply: It's a warning by which the compiler indicates that it cannot ensure type safety.

JPA service method for example:

@SuppressWarnings("unchecked")
public List<User> findAllUsers(){
    Query query = entitymanager.createQuery("SELECT u FROM User u");
    return (List<User>)query.getResultList();
}

If I didn'n anotate the @SuppressWarnings("unchecked") here, it would have a problem with line, where I want to return my ResultList.

In shortcut type-safety means: A program is considered type-safe if it compiles without errors and warnings and does not raise any unexpected ClassCastException s at runtime.

EDIT: and you can use Javascript, from the <a> tag (onclick event) to set iFrame' SRC attribute at run-time...

EDIT 2: Apparently, it is a bug (but there are workarounds):

PDF files do not open in Internet Explorer with Adobe Reader 10.0 - users get an empty gray screen. How can I fix this for my users?

You can always use a hidden div and use javascript to "popup" the div and have buttons that are like yes and or no. Pretty easy stuff to do.

I found that subplots_adjust(hspace = 0.001) is what ended up working for me. When I use space = None, there is still white space between each plot. Setting it to something very close to zero however seems to force them to line up. What I've uploaded here isn't the most elegant piece of code, but you can see how the hspace works.

import numpy as np
import matplotlib.pyplot as plt
import matplotlib.ticker as tic

fig = plt.figure()

x = np.arange(100)
y = 3.*np.sin(x*2.*np.pi/100.)

for i in range(5):
    temp = 510 + i
    ax = plt.subplot(temp)
    plt.plot(x,y)
    plt.subplots_adjust(hspace = .001)
    temp = tic.MaxNLocator(3)
    ax.yaxis.set_major_locator(temp)
    ax.set_xticklabels(())
    ax.title.set_visible(False)

plt.show()

Another situation when you may need this is if you have stl collection of pointers and want to change them using stl algorithm. Example of for_each in c++98.

struct Storage {
  typedef std::list<Object*> ObjectList;
  ObjectList objects;

  void change() {
    typedef void (*ChangeFunctionType)(Object*&);
    std::for_each<ObjectList::iterator, ChangeFunctionType>
                 (objects.begin(), objects.end(), &Storage::changeObject);
  }

  static void changeObject(Object*& item) {
    delete item;
    item = 0;
    if (someCondition) item = new Object();
  } 

};

Otherwise, if you use changeObject(Object* item) signature you have copy of pointer, not original one.

You should be able to uninstall it using sc.exe (I think it is included in the Windows Resource Kit) by running the following in an "administrator" command prompt:

sc.exe delete <service name>

where <service name> is the name of the service itself as you see it in the service management console, not of the exe.

You can find sc.exe in the System folder and it needs Administrative privileges to run. More information in this Microsoft KB article.

Alternatively, you can directly call the DeleteService() api. That way is a little more complex, since you need to get a handle to the service control manager via OpenSCManager() and so on, but on the other hand it gives you more control over what is happening.

You can use a2enmod or a2dismod to enable/disable modules by name.

From terminal, run: sudo a2enmod php5 to enable PHP5 (or some other module), then sudo service apache2 reload to reload the Apache2 configuration.

The only thing you have to do is to add in the cshtml file, in the head, the following line:

        @Styles.Render("~/Content/Main.css")

The entire head will look somethink like that:

    <head>
         <meta http-equiv="Content-Type" content="text/html; charset=UTF-8">
         <title>HTML Page</title>
         @Styles.Render("~/Content/main.css")
    </head>

Hope it helps!!

The best tool I have found is Appshow. Visit http://www.techsmith.com/techsmith-appshow.html (I do not work for them)

Reference is taken from this Article: A collation is a set of rules for comparing characters in a character set. It has also ruled for sorting of characters and proper order of two characters varies from language to language. A Collation compared two strings like, if a word is greater than another one, and sort accordingly.

If you are using “latin1” Character set, you can use “latin1_swedish_ci” Collation.

You have to choose right collation because wrong collation may affect your database performance.

Looking at the comments in the source:

Basically here we are simply checking whether we can call the java.sql.Connection methods for LOB creation added in JDBC 4. We not only check whether the java.sql.Connection declares these methods, but also whether the actual java.sql.Connection instance implements them (i.e. can be called without simply throwing an exception).

So, it's trying to determine if it can use some new JDBC 4 methods. I guess your driver may not support the new LOB creation method.

As offer_date is an number, and is of lower accuracy than your real dates, this may work...
- Convert your real date to a string of format YYYYMM
- Conver that value to an INT
- Compare the result you your offer_date

SELECT
  *
FROM
  offers
WHERE
    offer_date = (SELECT CAST(to_char(create_date, 'YYYYMM') AS INT) FROM customers where id = '12345678')
AND offer_rate > 0 

Also, by doing all the manipulation on the create_date you only do the processing on one value.

Additionally, had you manipulated the offer_date you would not be able to utilise any index on that field, and so force SCANs instead of SEEKs.

Open any file

import os
os.startfile(<filepath>)

The compiler doesn't get the intricate logic where you return in the last iteration of the loop, so it thinks that you could exit out of the loop and end up not returning anything at all.

Instead of returning in the last iteration, just return true after the loop:

public static bool isTwenty(int num) {
  for(int j = 1; j <= 20; j++) {
    if(num % j != 0) {
      return false;
    }
  }
  return true;
}

Side note, there is a logical error in the original code. You are checking if num == 20 in the last condition, but you should have checked if j == 20. Also checking if num % j == 0 was superflous, as that is always true when you get there.

A global JS variable (object) can be used to pass data between components. Example: Passing data from Ammlogin.vue to Options.vue. In Ammlogin.vue rspData is set to the response from the server. In Options.vue the response from the server is made available via rspData.

index.html:

<script>
    var rspData; // global - transfer data between components
</script>

Ammlogin.vue:

....    
export default {
data: function() {return vueData}, 
methods: {
    login: function(event){
        event.preventDefault(); // otherwise the page is submitted...
        vueData.errortxt = "";
        axios.post('http://vueamm...../actions.php', { action: this.$data.action, user: this.$data.user, password: this.$data.password})
            .then(function (response) {
                vueData.user = '';
                vueData.password = '';
                // activate v-link via JS click...
                // JSON.parse is not needed because it is already an object
                if (response.data.result === "ok") {
                    rspData = response.data; // set global rspData
                    document.getElementById("loginid").click();
                } else {
                    vueData.errortxt = "Felaktig avändare eller lösenord!"
                }
            })
            .catch(function (error) {
                // Wu oh! Something went wrong
                vueData.errortxt = error.message;
            });
    },
....

Options.vue:

Run following command in git bash that works fine for me

git config --global http.sslverify "false"

Yes... by the time the regex compiler sees the pattern you've given it, it sees only a single backslash (since Java's lexer has turned the double backwhack into a single one). You need to replace "\\\\" with "\\\\", believe it or not! Java really needs a good raw string syntax.

Create a temp file first.

File tempFile = File.createTempFile(prefix, suffix);
tempFile.deleteOnExit();
FileOutputStream out = new FileOutputStream(tempFile);
IOUtils.copy(in, out);
return tempFile;

You have to do the following:

if "%1" == "" (
    echo The variable is empty
) ELSE (
    echo The variable contains %1
)

If an URL pattern starts with /, then it's relative to the context root. The /Admin/* URL pattern would only match pages on http://localhost:8080/EMS2/Admin/* (assuming that /EMS2 is the context path), but you have them actually on http://localhost:8080/EMS2/faces/Html/Admin/*, so your URL pattern never matches.

You need to prefix your URL patterns with /faces/Html as well like so:

<url-pattern>/faces/Html/Admin/*</url-pattern>

You can alternatively also just reconfigure your web project structure/configuration so that you can get rid of the /faces/Html path in the URLs so that you can just open the page by for example http://localhost:8080/EMS2/Admin/Upload.xhtml.

Your filter mapping syntax is all fine. However, a simpler way to specify multiple URL patterns is to just use only one <filter-mapping> with multiple <url-pattern> entries:

<filter-mapping>
    <filter-name>LoginFilter</filter-name>
    <url-pattern>/faces/Html/Employee/*</url-pattern>
    <url-pattern>/faces/Html/Admin/*</url-pattern>
    <url-pattern>/faces/Html/Supervisor/*</url-pattern>
</filter-mapping>

First of all, you need not do var r = this; as this in if statement refers to the context of the callback itself which since you are using arrow function refers to the React component context.

According to the docs:

history objects typically have the following properties and methods:

• length - (number) The number of entries in the history stack
• action - (string) The current action (PUSH, REPLACE, or POP)

• location - (object) The current location. May have the following properties:

  • pathname - (string) The path of the URL
  • search - (string) The URL query string
  • hash - (string) The URL hash fragment
  • state - (string) location-specific state that was provided to e.g. push(path, state) when this location was pushed onto the stack. Only available in browser and memory history.
• push(path, [state]) - (function) Pushes a new entry onto the history stack
• replace(path, [state]) - (function) Replaces the current entry on the history stack
• go(n) - (function) Moves the pointer in the history stack by n entries
• goBack() - (function) Equivalent to go(-1)
• goForward() - (function) Equivalent to go(1)
• block(prompt) - (function) Prevents navigation

So while navigating you can pass props to the history object like

this.props.history.push({
  pathname: '/template',
  search: '?query=abc',
  state: { detail: response.data }
})

or similarly for the Link component or the Redirect component

<Link to={{
      pathname: '/template',
      search: '?query=abc',
      state: { detail: response.data }
    }}> My Link </Link>

and then in the component which is rendered with /template route, you can access the props passed like

this.props.location.state.detail

Also keep in mind that, when using history or location objects from props you need to connect the component with withRouter.

As per the Docs:

withRouter

You can get access to the history object’s properties and the closest <Route>'s match via the withRouter higher-order component. withRouter will re-render its component every time the route changes with the same props as <Route> render props: { match, location, history }.

From the python command prompt:

import scipy
print scipy.__version__

In python 3 you'll need to change it to:

print (scipy.__version__)

Stub - an object that provides predefined answers to method calls.

Mock - an object on which you set expectations.

Fake - an object with limited capabilities (for the purposes of testing), e.g. a fake web service.

Test Double is the general term for stubs, mocks and fakes. But informally, you'll often hear people simply call them mocks.

I think it would be better to actually bind your listBoxes to a datasource, since it looks like you are adding the same elements to each listbox. A simple example would be something like this:

    private List<String> _weight = new List<string>() { "kilogram", "pound" };
    private List<String> _height = new List<string>() { "foot", "inch", "meter" };

    public Window1()
    {            
        InitializeComponent();
    }        

    private void Weight_Click(object sender, RoutedEventArgs e)
    {
        listBox1.ItemsSource = _weight;
        listBox2.ItemsSource = _weight;
    }

    private void Height_Click(object sender, RoutedEventArgs e)
    {
        listBox1.ItemsSource = _height;
        listBox2.ItemsSource = _height;
    }

Add

"rnpm": {
  "assets": [
 "./assets/fonts/"
  ]
}

in package.json then run react-native link

I think you missed the mysql driver for php5. Execute below command:

sudo apt-get install php5-mysql
/etc/init.d/php5-fpm restart

1. In your project folder, create a “.gdbinit” text file. It will contain your gdb debugger configuration
2. Edit “.gdbinit”, and add the line (without the quotes) : “set new-console on”

3. After building the project right click on the project Debug > “Debug Configurations”, as shown below

4. In the “debugger” tab, ensure the “GDB command file” now points to your “.gdbinit” file. Else, input the path to your “.gdbinit” configuration file :

5. Click “Apply” and “Debug”. A native DOS command line should be launched as shown below

Late to this one, but I just discovered an alternative way of doing it:

On your template,

<a (click)="navigateAssociates()">Associates</a> 

And on your component.ts, you can use serializeUrl to convert the route into a string, which can be used with window.open()

navigateAssociates() {
  const url = this.router.serializeUrl(
    this.router.createUrlTree(['/page1'])
  );

  window.open(url, '_blank');
}

There are three types of variables:

• Instance variables: are always initialized
• Static variables: are always initialized
• Local variables: must be initialized before use

The default values for instance and static variables are the same and depends on the type:

• Object type (String, Integer, Boolean and others): initialized with null
• Primitive types:
  • byte, short, int, long: 0
  • float, double: 0.0
  • boolean: false
  • char: '\u0000'

An array is an Object. So an array instance variable that is declared but no explicitly initialized will have null value. If you declare an int[] array as instance variable it will have the null value.

Once the array is created all of its elements are assiged with the default type value. For example:

private boolean[] list; // default value is null

private Boolean[] list; // default value is null

once is initialized:

private boolean[] list = new boolean[10]; // all ten elements are assigned to false

private Boolean[] list = new Boolean[10]; // all ten elements are assigned to null (default Object/Boolean value)

Also checkout the answer in this post: https://stackoverflow.com/a/9347871/1338557

It suggests use of library called ucsv.py. Short and simple replacement for CSV written to address the encoding problem(utf-8) for Python 2.7. Also provides support for csv.DictReader

Edit: Adding sample code that I used:

import ucsv as csv

#Read CSV file containing the right tags to produce
fileObj = open('awol_title_strings.csv', 'rb')
dictReader = csv.DictReader(fileObj, fieldnames = ['titles', 'tags'], delimiter = ',', quotechar = '"')
#Build a dictionary from the CSV file-> {<string>:<tags to produce>}
titleStringsDict = dict()
for row in dictReader:
    titleStringsDict.update({unicode(row['titles']):unicode(row['tags'])})

Check your project build is in Debug mode not Release, I had some problem for debugging always I forget to change Release mode to Debug (Xamarin Users)

I disagree with that this:

String s = myObj == null ? "" : myObj.ToString();

is a hack in any way. I think it's a good example of clear code. It's absolutely obvious what you want to achieve and that you're expecting null.

UPDATE:

I see now that you were not saying that this was a hack. But it's implied in the question that you think this way is not the way to go. In my mind it's definitely the clearest solution.

This is going to work :

If you have any NamedQueries in your entity classes, then check the stack trace for compilation errors. A malformed query which cannot be compiled can cause failure to load the persistence context.

If you wish to escape HTML in a URL:

This is probably NOT what the OP wanted (the question doesn't clearly indicate in which context the escaping is meant to be used), but Python's native library urllib has a method to escape HTML entities that need to be included in a URL safely.

The following is an example:

#!/usr/bin/python
from urllib import quote

x = '+<>^&'
print quote(x) # prints '%2B%3C%3E%5E%26'

What hasn't been mentioned here is described in this article in the paragraph "Order of execution".

After "learning" that I had to annotate a class with @Component or the derivatives @Service or @Repository (I guess there are more), to autowire other components inside them, it struck me that these other components still were null inside the constructor of the parent component.

Using @PostConstruct solves that:

@SpringBootApplication
public class Application {
    @Autowired MyComponent comp;
}

and:

@Component
public class MyComponent {
    @Autowired ComponentDAO dao;

    public MyComponent() {
        // dao is null here
    }

    @PostConstruct
    public void init() {
        // dao is initialized here
    }
}

I want change default directory dumpfile.

You could create a new directory and give it required privileges, for example:

SQL> CREATE DIRECTORY dmpdir AS '/opt/oracle';
Directory created.

SQL> GRANT read, write ON DIRECTORY dmpdir TO scott;
Grant succeeded.

To use the newly created directory, you could just add it as a parameter:

DIRECTORY=dmpdir

Oracle introduced a default directory from 10g R2, called DATA_PUMP_DIR, that can be used. To check the location, you could look into dba_directories:

SQL> select DIRECTORY_NAME, DIRECTORY_PATH from dba_directories where DIRECTORY_NAME = 'DATA_PUMP_DIR';

DIRECTORY_NAME       DIRECTORY_PATH
-------------------- --------------------------------------------------
DATA_PUMP_DIR        C:\app\Lalit/admin/orcl/dpdump/

SQL>

You can print in simple way.

Use below to print 2D array

int[][] array = new int[rows][columns];
System.out.println(Arrays.deepToString(array));

Use below to print 1D array

int[] array = new int[size];
System.out.println(Arrays.toString(array));

I was referencing a mapped drive and I found that the mapped drives are not always available to the user account that is running the scheduled task so I used \\IPADDRESS instead of MAPDRIVELETTER: and I am up and running.

To let your shell expand the variable, you need to use double-quotes like

sed -i "s#12345678#$replace#g" file.txt

This will break if $replace contain special sed characters (#, \). But you can preprocess $replace to quote them:

replace_quoted=$(printf '%s' "$replace" | sed 's/[#\]/\\\0/g')
sed -i "s#12345678#$replace_quoted#g" file.txt

Example for you to work from

phpMyAdmin provides a GUI for this within the structure view of a table. Check to select the column you want to move and click the change action at the bottom of the column list. You can then change all of the column properties and you'll find the 'move column' function at the far right of the screen.

Of course this is all just building the queries in the perfectly good top answer but GUI fans might appreciate the alternative.

my phpMyAdmin version is 4.1.7

I really love var_export(). If you like copy/paste-able code, try:

echo '<pre>' . var_export($data, true) . '</pre>';

Or even something like this for color syntax highlighting:

highlight_string("<?php\n\$data =\n" . var_export($data, true) . ";\n?>");

You can do the same with print_r(). For var_dump() you would just need to add the <pre> tags:

echo '<pre>';
var_dump($data);
echo '</pre>';

By getting the getLastKnownLocation you do not actually initiate a fix yourself.

Be aware that this could start the provider, but if the user has ever gotten a location before, I don't think it will. The docs aren't really too clear on this.

According to the docs getLastKnownLocation:

Returns a Location indicating the data from the last known location fix obtained from the given provider. This can be done without starting the provider.

Here is a quick snippet:

import android.content.Context;
import android.location.Location;
import android.location.LocationManager;
import java.util.List;

public class UtilLocation {
    public static Location getLastKnownLoaction(boolean enabledProvidersOnly, Context context){
        LocationManager manager = (LocationManager) context.getSystemService(Context.LOCATION_SERVICE);
        Location utilLocation = null;
        List<String> providers = manager.getProviders(enabledProvidersOnly);
        for(String provider : providers){

            utilLocation = manager.getLastKnownLocation(provider);
            if(utilLocation != null) return utilLocation;
        }
        return null;
    }
}

You also have to add new permission to AndroidManifest.xml

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

In the case you want to download a single file, you can try the following command:

aws s3 cp s3://bucket/filename /path/to/dest/folder

Ctrl + H is the best way! Remember to copy the string before you start searching!

index.html

<input id="suby" type="submit" value="Remove DUMMY"/>

myscripts.js

document.addEventListener("DOMContentLoaded", {
//Do this AFTER elements are loaded

    document.getElementById("suby").addEventListener("click", e => {
        document.getElementById("dummy").remove()
    })

})

Yes, you can do this. The knack you need is the concept that there are two ways of getting tables out of the table server. One way is ..

FROM TABLE A

The other way is

FROM (SELECT col as name1, col2 as name2 FROM ...) B

Notice that the select clause and the parentheses around it are a table, a virtual table.

So, using your second code example (I am guessing at the columns you are hoping to retrieve here):

SELECT a.attr, b.id, b.trans, b.lang
FROM attribute a
JOIN (
 SELECT at.id AS id, at.translation AS trans, at.language AS lang, a.attribute
 FROM attributeTranslation at
) b ON (a.id = b.attribute AND b.lang = 1)

Notice that your real table attribute is the first table in this join, and that this virtual table I've called b is the second table.

This technique comes in especially handy when the virtual table is a summary table of some kind. e.g.

SELECT a.attr, b.id, b.trans, b.lang, c.langcount
FROM attribute a
JOIN (
 SELECT at.id AS id, at.translation AS trans, at.language AS lang, at.attribute
 FROM attributeTranslation at
) b ON (a.id = b.attribute AND b.lang = 1)
JOIN (
 SELECT count(*) AS langcount,  at.attribute
 FROM attributeTranslation at
 GROUP BY at.attribute
) c ON (a.id = c.attribute)

See how that goes? You've generated a virtual table c containing two columns, joined it to the other two, used one of the columns for the ON clause, and returned the other as a column in your result set.

I had the same problem, and a easy way i found to solve that was to make everything in the modal's body responsive(using boostrap classes) and my problem were solved.

The most secure way to accomplish this is using Int32.TryParse method. See here: http://dotnetperls.com/int-tryparse

You should not rely on a hash code being equal to a specific value. Just that it will return consistent results within the same execution. The API docs say the following :

The general contract of hashCode is:

• Whenever it is invoked on the same object more than once during an execution of a Java application, the hashCode method must consistently return the same integer, provided no information used in equals comparisons on the object is modified. This integer need not remain consistent from one execution of an application to another execution of the same application.

EDIT Since the javadoc for String.hashCode() specifies how a String's hash code is computed, any violation of this would violate the public API specification.

They're essentially the same, if your program is run from an interactive prompt and you haven't redirected stdin or stdout:

public class ConsoleTest {
    public static void main(String[] args) {
        System.out.println("Console is: " + System.console());
    }
}

results in:

$ java ConsoleTest
Console is: java.io.Console@2747ee05
$ java ConsoleTest </dev/null
Console is: null
$ java ConsoleTest | cat
Console is: null

The reason Console exists is to provide features that are useful in the specific case that you're being run from an interactive command line:

• secure password entry (hard to do cross-platform)
• synchronisation (multiple threads can prompt for input and Console will queue them up nicely, whereas if you used System.in/out then all of the prompts would appear simultaneously).

Notice above that redirecting even one of the streams results in System.console() returning null; another irritation is that there's often no Console object available when spawned from another program such as Eclipse or Maven.

This blog post describes two methods of centering a div both horizontally and vertically. One uses only CSS and will work with divs that have a fixed size; the other uses jQuery and will work divs for which you do not know the size in advance.

I've duplicated the CSS and jQuery examples from the blog post's demo here:

CSS

Assuming you have a div with a class of .classname, the css below should work.

The left:50%; top:50%; sets the top left corner of the div to the center of the screen; the margin:-75px 0 0 -135px; moves it to the left and up by half of the width and height of the fixed-size div respectively.

.className{
    width:270px;
    height:150px;
    position:absolute;
    left:50%;
    top:50%;
    margin:-75px 0 0 -135px;
}

jQuery

$(document).ready(function(){
    $(window).resize(function(){
        $('.className').css({
            position:'absolute',
            left: ($(window).width() - $('.className').outerWidth())/2,
            top: ($(window).height() - $('.className').outerHeight())/2
        });
    });
    // To initially run the function:
    $(window).resize();
});

Here's a demo of the techniques in practice.

just in case someone comes to this question, I have the easier version.

public static MediaPlayer mp;
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        Button b = (Button) findViewById(R.id.button);
        Button b2 = (Button) findViewById(R.id.button2);


        b.setOnClickListener(new View.OnClickListener() {

            @Override
            public void onClick(View v) {
                mp = MediaPlayer.create(MainActivity.this, R.raw.game);
                mp.start();
            }
        });

        b2.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                mp.stop();
               // mp.start();
            }
        });
    }

http://www.markrafferty.com/wp-content/w3tc/min/7415c412.e68ae1.css

Line 11:

.postItem img {
    height: auto;
    width: 450px;
}

You can either edit your CSS, or you can listen to Mageek and use INLINE STYLING to override the CSS styling that's happening:

<img src="theSource" style="width:30px;" />

Avoid setting both width and height, as the image itself might not be scaled proportionally. But you can set the dimensions to whatever you want, as per Mageek's example.

You can use the iOS simulator to do this. You need to enable "Developer Mode" on Safari (Preferences -> Advanced).

Then open the website you want to debug in the iOS simulator. Go back to safari and under Develop you will see the simulator and the tabs open on safari.

If you want to test an actual device, then just plug it into your computer and it should show there too.

That's how I do it.

// using so that Marshal doesn't have to be qualified
using System.Runtime.InteropServices;    
//using for SecureString
using System.Security;
public string DecodeSecureString (SecureString Convert) 
{
    //convert to IntPtr using Marshal
    IntPtr cvttmpst = Marshal.SecureStringToBSTR(Convert);
    //convert to string using Marshal
    string cvtPlainPassword = Marshal.PtrToStringAuto(cvttmpst);
    //return the now plain string
    return cvtPlainPassword;
}

Perhaps you could try to use the of method of the Observable class:

import { Observable } from 'rxjs/Observable';
import 'rxjs/add/observable/of';

public fetchModel(uuid: string = undefined): Observable<string> {
  if(!uuid) {
    return Observable.of(new TestModel()).map(o => JSON.stringify(o));
  }
  else {
    return this.http.get("http://localhost:8080/myapp/api/model/" + uuid)
            .map(res => res.text());
  }
}

The short answer:

A const is a promise that you will not try to modify the value once set.

A static variable means that the object's lifetime is the entire execution of the program and it's value is initialized only once before the program startup. All statics are initialized if you do not explicitly set a value to them.The manner and timing of static initialization is unspecified.

C99 borrowed the use of const from C++. On the other hand, static has been the source of many debates (in both languages) because of its often confusing semantics.

Also, with C++0x until C++11 the use of the static keyword was deprecated for declaring objects in namespace scope. This deprecation was removed in C++11 for various reasons (see here).

The longer answer: More on the keywords than you wanted to know (right from the standards):

C99

#include <fenv.h>
#pragma STDC FENV_ACCESS ON

/* file scope, static storage, internal linkage */
static int i1; // tentative definition, internal linkage
extern int i1; // tentative definition, internal linkage

int i2; // external linkage, automatic duration (effectively lifetime of program)

int *p = (int []){2, 4}; // unnamed array has static storage

/* effect on string literals */
char *s = "/tmp/fileXXXXXX"; // static storage always, may not be modifiable
char *p = (char []){"/tmp/fileXXXXXX"}; // static, modifiable
const char *cp = (const char []){"/tmp/fileXXXXXX"}  // static, non-modifiable


void f(int m)
{
    static int vla[ m ]; // err

    float w[] = { 0.0/0.0 }; // raises an exception

    /* block scope, static storage, no-linkage */
    static float x = 0.0/0.0; // does not raise an exception
    /* ... */
     /* effect on string literals */
    char *s = "/tmp/fileXXXXXX"; // static storage always, may not be modifiable
    char *p = (char []){"/tmp/fileXXXXXX"}; // automatic storage, modifiable
    const char *cp = (const char []){"/tmp/fileXXXXXX"}  // automatic storage, non-modifiable

}

inline void bar(void)
{
     const static int x = 42; // ok
     // Note: Since an inline definition is distinct from the 
     // corresponding external definition and from any other
     // corresponding inline definitions in other translation 
     // units, all corresponding objects with static storage
     // duration are also distinct in each of the definitions
     static int y = -42; // error, inline function definition
}

// the last declaration also specifies that the argument 
// corresponding to a in any call to f must be a non-null 
// pointer to the first of at least three arrays of 5 doubles
void f(double a[static 3][5]);

static void g(void); // internal linkage

C++

Has the same semantics mostly except as noted in the short answer. Also, there are no parameter qualifying statics.

extern "C" {
static void f4(); // the name of the function f4 has
                  // internal linkage (not C language
                  // linkage) and the function’s type
                  // has C language linkage.
}

class S {
   mutable static int i; // err
   mutable static int j; // err
   static int k; // ok, all instances share the same member
};

inline void bar(void)
{
     const static int x = 42; // ok
     static int y = -42; // ok
}

There are a few more nuances of C++'s static that I leave out here. Have a look at a book or the standard.

Not tested but should work:

$("#MyDiv td input:checked").each(function()
{
    alert($(this).attr("id"));
});

I had both the Lombok plugin installed and Annotation Processing enabled within IntelliJ and my syntax highlighting still wasn't working properly. This could have been due to the 2017 to 2018 IDEA upgrade. I was getting warnings "access exceeds rights" on private fields within classes I had used @Getter and @Setter on.

I had to uninstall the Lombok plugin, restart IntelliJ, then reinstall the plugin, and restart IntelliJ once more.

Everything is working good now.

This worked for me!!!!

The _t data types are typedef types in the stdint.h header, while int is an in built fundamental data type. This make the _t available only if stdint.h exists. int on the other hand is guaranteed to exist.

Initializer block is just like any bits of code; it's not "attached" to any field/method preceding it. To assign values to fields, you have to explicitly use the field as the lhs of an assignment statement.

private int lineCount; {
    try{
        lineCount = LineCounter.countLines(sFileName);
        /*^^^^^^^*/
    }
    catch(IOException ex){
        System.out.println (ex.toString());
        System.out.println("Could not find file " + sFileName);
    }
}

Also, your countLines can be made simpler:

  public static int countLines(String filename) throws IOException {
    LineNumberReader reader  = new LineNumberReader(new FileReader(filename));
    while (reader.readLine() != null) {}
    reader.close();
    return reader.getLineNumber();
  }

Based on my test, it looks like you can getLineNumber() after close().

Securiy Warning: This code is insecure. In addition to being vulnerable to chosen-ciphertext attacks, its reliance on unserialize() makes it vulnerable to PHP Object Injection.

To handle a string / array I use these two functions:

function encryptStringArray ($stringArray, $key = "Your secret salt thingie") {
 $s = strtr(base64_encode(mcrypt_encrypt(MCRYPT_RIJNDAEL_256, md5($key), serialize($stringArray), MCRYPT_MODE_CBC, md5(md5($key)))), '+/=', '-_,');
 return $s;
}

function decryptStringArray ($stringArray, $key = "Your secret salt thingie") {
 $s = unserialize(rtrim(mcrypt_decrypt(MCRYPT_RIJNDAEL_256, md5($key), base64_decode(strtr($stringArray, '-_,', '+/=')), MCRYPT_MODE_CBC, md5(md5($key))), "\0"));
 return $s;
}

It's flexible as in you can store/send via URL a string or array because the string/array is serialzed before encryption.

For Symfony projects, be sure to check files in the project'es app/logs

Btw, other frameworks or CMS share this kind of behaviour.

Spring lets you define multiple contexts in a parent-child hierarchy.

The applicationContext.xml defines the beans for the "root webapp context", i.e. the context associated with the webapp.

The spring-servlet.xml (or whatever else you call it) defines the beans for one servlet's app context. There can be many of these in a webapp, one per Spring servlet (e.g. spring1-servlet.xml for servlet spring1, spring2-servlet.xml for servlet spring2).

Beans in spring-servlet.xml can reference beans in applicationContext.xml, but not vice versa.

All Spring MVC controllers must go in the spring-servlet.xml context.

In most simple cases, the applicationContext.xml context is unnecessary. It is generally used to contain beans that are shared between all servlets in a webapp. If you only have one servlet, then there's not really much point, unless you have a specific use for it.

On Microsoft SQL Server Management Studio 2019:

On Restore Database window:

1. Choose Device

2. Choose Add and pick target file

3. OK to confirm

4. OK to confirm restore

I also tried using pymysql (on my Win7 x64 machine, Python 3.3), without too much luck. I downloaded the .tar.gz, extract, ran "setup.py install", and everything seemed fine. Until I tried connecting to a database, and got "KeyError [56]". An error which I was unable to find documented anywhere.

So I gave up on pymysql, and I settled on the Oracle MySQL connector.

It comes as a setup package, and works out of the box. And it also seems decently documented.

Back in 2008 this wasn't important because of the lack of mobile OS'es but now quite important thing.

When you set accepted mime types, then in for example Android user is given system dialog with apps which can provide him the content of mime which file input accepts, what is great because navigating through files in file explorer on mobile devices is slow and often stressful.

One important thing is that some mobile browsers (based on Android version of Chrome 36 and Chrome Beta 37) does not support app filtering over extension(s) and multiple mime types.

You don't need JavaScript for this. You can change the cursor to anything you want using CSS :

selector {
    cursor: url(myimage.jpg), auto;
}

See here for browser support as there are some subtle differences depending on browser

Swift3 has changed to :

let multiples = [...]
sum = multiples.reduce(0, +)

I would use Box-Muller. Two things about this:

1. You end up with two values per iteration
   Typically, you cache one value and return the other. On the next call for a sample, you return the cached value.
2. Box-Muller gives a Z-score
   You have to then scale the Z-score by the standard deviation and add the mean to get the full value in the normal distribution.

How about onblur event :

<input type="text" name="name" value="value" onblur="alert(1);"/>

Here are some functions I created for working with fullscreen in the browser.

They provide both enter/exit fullscreen across most major browsers.

function isFullScreen()
{
    return (document.fullScreenElement && document.fullScreenElement !== null)
         || document.mozFullScreen
         || document.webkitIsFullScreen;
}


function requestFullScreen(element)
{
    if (element.requestFullscreen)
        element.requestFullscreen();
    else if (element.msRequestFullscreen)
        element.msRequestFullscreen();
    else if (element.mozRequestFullScreen)
        element.mozRequestFullScreen();
    else if (element.webkitRequestFullscreen)
        element.webkitRequestFullscreen();
}

function exitFullScreen()
{
    if (document.exitFullscreen)
        document.exitFullscreen();
    else if (document.msExitFullscreen)
        document.msExitFullscreen();
    else if (document.mozCancelFullScreen)
        document.mozCancelFullScreen();
    else if (document.webkitExitFullscreen)
        document.webkitExitFullscreen();
}

function toggleFullScreen(element)
{
    if (isFullScreen())
        exitFullScreen();
    else
        requestFullScreen(element || document.documentElement);
}

In your xml file just use a instead of the tag. The inflater tries to create an android.app.Fragment from which will fail on API < 10. So you need to create a view group of a different type.

You can use either of these two scripts to open the URLs in separate tabs in a (single) new IE window. You can call either of these scripts from within your batch script (or at the command prompt):

JavaScript
Create a file with a name like: "urls.js":

var navOpenInNewWindow = 0x1;
var navOpenInNewTab = 0x800;
var navOpenInBackgroundTab = 0x1000;

var intLoop = 0;
var intArrUBound = 0;
var navFlags = navOpenInBackgroundTab;
var arrstrUrl = new Array(3);
var objIE;

    intArrUBound = arrstrUrl.length;

    arrstrUrl[0] = "http://bing.com/";
    arrstrUrl[1] = "http://google.com/";
    arrstrUrl[2] = "http://msn.com/";
    arrstrUrl[3] = "http://yahoo.com/";

    objIE = new ActiveXObject("InternetExplorer.Application");
    objIE.Navigate2(arrstrUrl[0]);

    for (intLoop=1;intLoop<=intArrUBound;intLoop++) {

        objIE.Navigate2(arrstrUrl[intLoop], navFlags);

    }

    objIE.Visible = true;
    objIE = null;

VB Script
Create a file with a name like: "urls.vbs":

Option Explicit

Const navOpenInNewWindow = &h1
Const navOpenInNewTab = &h800
Const navOpenInBackgroundTab = &h1000

Dim intLoop       : intLoop = 0
Dim intArrUBound  : intArrUBound = 0
Dim navFlags      : navFlags = navOpenInBackgroundTab

Dim arrstrUrl(3)
Dim objIE

    intArrUBound = UBound(arrstrUrl)

    arrstrUrl(0) = "http://bing.com/"
    arrstrUrl(1) = "http://google.com/"
    arrstrUrl(2) = "http://msn.com/"
    arrstrUrl(3) = "http://yahoo.com/"

    set objIE = CreateObject("InternetExplorer.Application")
    objIE.Navigate2 arrstrUrl(0)

    For intLoop = 1 to intArrUBound

        objIE.Navigate2 arrstrUrl(intLoop), navFlags

    Next

    objIE.Visible = True
    set objIE = Nothing

Once you decide on "JavaScript" or "VB Script", you have a few choices:

If your URLs are static:

1) You could write the "JS/VBS" script file (above) and then just call it from a batch script.

From within the batch script (or command prompt), call the "JS/VBS" script like this:

cscript //nologo urls.vbs
cscript //nologo urls.js

If the URLs change infrequently:

2) You could have the batch script write the "JS/VBS" script on the fly and then call it.

If the URLs could be different each time:

3) Use the "JS/VBS" scripts (below) and pass the URLs of the pages to open as command line arguments:

JavaScript
Create a file with a name like: "urls.js":

var navOpenInNewWindow = 0x1;
var navOpenInNewTab = 0x800;
var navOpenInBackgroundTab = 0x1000;

var intLoop = 0;
var navFlags = navOpenInBackgroundTab;
var objIE;
var intArgsLength = WScript.Arguments.Length;

    if (intArgsLength == 0) {

        WScript.Echo("Missing parameters");
        WScript.Quit(1);

    }

    objIE = new ActiveXObject("InternetExplorer.Application");
    objIE.Navigate2(WScript.Arguments(0));

    for (intLoop=1;intLoop<intArgsLength;intLoop++) {

        objIE.Navigate2(WScript.Arguments(intLoop), navFlags);

    }

    objIE.Visible = true;
    objIE = null;

VB Script
Create a file with a name like: "urls.vbs":

Option Explicit

Const navOpenInNewWindow = &h1
Const navOpenInNewTab = &h800
Const navOpenInBackgroundTab = &h1000

Dim intLoop
Dim navFlags      : navFlags = navOpenInBackgroundTab
Dim objIE

    If WScript.Arguments.Count = 0 Then

        WScript.Echo "Missing parameters"
        WScript.Quit(1)

    End If

    set objIE = CreateObject("InternetExplorer.Application")
    objIE.Navigate2 WScript.Arguments(0)

    For intLoop = 1 to (WScript.Arguments.Count-1)

        objIE.Navigate2 WScript.Arguments(intLoop), navFlags

    Next

    objIE.Visible = True
    set objIE = Nothing

If the script is called without any parameters, these will return %errorlevel%=1, otherwise they will return %errorlevel%=0. No checking is done regarding the "validity" or "availability" of any of the URLs.

From within the batch script (or command prompt), call the "JS/VBS" script like this:

cscript //nologo urls.js "http://bing.com/" "http://google.com/" "http://msn.com/" "http://yahoo.com/"
cscript //nologo urls.vbs "http://bing.com/" "http://google.com/" "http://msn.com/" "http://yahoo.com/"

OR even:

cscript //nologo urls.js "bing.com" "google.com" "msn.com" "yahoo.com"
cscript //nologo urls.vbs "bing.com" "google.com" "msn.com" "yahoo.com"

If for some reason, you wanted to run these with "wscript" instead, remember to use "start /w" so the exit codes (%errorlevel%) will be returned to your batch script:

start /w "" wscript //nologo urls.js "url1" "url2" ...
start /w "" wscript //nologo urls.vbs "url1" "url2" ...

There has been a comment that my solution is too complicated. I disagree. You pick the JavaScript solution, or the VB Script solution (not both), and each is only about 10 lines of actual code (less if you eliminate the error checking/reporting), plus a few lines to initialize constants and variables.

Once you have decided (JS or VB), you write that script one time, and then you call that script from batch, passing the URLs, anytime you want to use it, like:

cscript //nologo urls.vbs "bing.com" "google.com" "msn.com" "yahoo.com"

The reason I wrote this answer, is because all the other answers, which work for some people, will fail to work for others, depending on:

1. The current Internet Explorer settings for "open popups in a new tab", "open in current/new window/tab", etc... Assuming you already have those setting set how you like them for general browsing, most people would find it undesirable to have change those settings back and forth in order to make the script work.
2. Their behavior is (can be) inconsistent depending on whether or not there was an IE window already open before the "new" links were opened. If there was an IE window (perhaps with many open tabs) already open, then all the new tabs would be added there as well. This might not be desired.

The solution I provided doesn't have these issues and should behave the same, regardless of any IE Settings or any existing IE Windows. (Please let me know if I'm wrong about this and I'll try to address it.)

The task above can be completed in two simple steps.

STEP 1:

CREATE table new_table_name AS(Select * from old_table_name);

The query above creates a duplicate of a table (with contents as well).

To get the structure, delete the contents of the table using.

STEP 2:

DELETE * FROM new_table_name.

Hope this solves your problem. And thanks to the earlier posts. Gave me a lot of insight.

In my case, I deleted the Previous Project & created a new project with different name, when i was building the Project it shows me the same error.

I just edited the Project Name in csproj file of the Project & it Worked...!

import sys
for x in range(10000):
    print "HAPPY >> %s <<\r" % str(x),
    sys.stdout.flush()

From EL 2.2 specification (get the one below "Click here to download the spec for evaluation"):

1.10 Empty Operator - empty A

The empty operator is a prefix operator that can be used to determine if a value is null or empty.

To evaluate empty A

• If A is null, return true
• Otherwise, if A is the empty string, then return true
• Otherwise, if A is an empty array, then return true
• Otherwise, if A is an empty Map, return true
• Otherwise, if A is an empty Collection, return true
• Otherwise return false

So, considering the interfaces, it works on Collection and Map only. In your case, I think Collection is the best option. Or, if it's a Javabean-like object, then Map. Either way, under the covers, the isEmpty() method is used for the actual check. On interface methods which you can't or don't want to implement, you could throw UnsupportedOperationException.

One way to achieve it, is by map your welcome-file to your controller request path in the web.xml file:

[web.xml]

<web-app ...

<!-- Index -->
<welcome-file-list>
    <welcome-file>home</welcome-file>
</welcome-file-list>

</web-app>

[LoginController.java]

@Controller("loginController")
public class LoginController{

@RequestMapping("/home")
public String homepage2(ModelMap model, HttpServletRequest request, HttpServletResponse response){
    System.out.println("blablabla2");
    model.addAttribute("sigh", "lesigh");
    return "index";
}

You can simply save your data in a variable and use find(to get single object of records) or filter(to get single array of records) method of JavaScript.

For example :-

let data = {
 "list": [
   {"name":"my Name","id":12,"type":"car owner"},
   {"name":"my Name2","id":13,"type":"car owner2"},
   {"name":"my Name4","id":14,"type":"car owner3"},
   {"name":"my Name4","id":15,"type":"car owner5"}
]}

and now use below command onkeyup or enter

to get single object

data.list.find( record => record.name === "my Name")

to get single array object

data.list.filter( record => record.name === "my Name")

If you have installed Batarang

Then you can just write:

$scope

when you have the element selected in the elements view in chrome. Ref - https://github.com/angular/angularjs-batarang#console

First note that with numpy's broadcasting operations it's usually not necessary to duplicate rows and columns. See this and this for descriptions.

But to do this, repeat and newaxis are probably the best way

In [12]: x = array([1,2,3])

In [13]: repeat(x[:,newaxis], 3, 1)
Out[13]: 
array([[1, 1, 1],
       [2, 2, 2],
       [3, 3, 3]])

In [14]: repeat(x[newaxis,:], 3, 0)
Out[14]: 
array([[1, 2, 3],
       [1, 2, 3],
       [1, 2, 3]])

This example is for a row vector, but applying this to a column vector is hopefully obvious. repeat seems to spell this well, but you can also do it via multiplication as in your example

In [15]: x = array([[1, 2, 3]])  # note the double brackets

In [16]: (ones((3,1))*x).transpose()
Out[16]: 
array([[ 1.,  1.,  1.],
       [ 2.,  2.,  2.],
       [ 3.,  3.,  3.]])

You can get it using the :selected selector, like this:

$("#my_select").change(function() {
  var id = $(this).children(":selected").attr("id");
});

If BalusC answer doesn't work try this:

.companyHeaderGrid td {
     border-style: hidden !important;
}

You can install this Jenkins Console log plugin to write the log in your workspace as a post build step.

You have to build the plugin yourself and install the plugin manually.

Next, you can add a post build step like that:

With an additional post build step (shell script), you will be able to grep your log.

I hope it helped :)

The getChars string method does not return a value, instead it dumps its result into your buffer (or destination) array. The index parameter describes the start offset in your destination array.

Try this link for a more verbose description of the getChars method.

I agree with the others on this, I think substring would be a better way to handle what you're trying to accomplish.

You can simply create a bat file in any convenient place and drop any file from the desired directory onto it. Haha. Code for this:

cmd

There is a trick to have both timestamps, but with a little limitation.

You can use only one of the definitions in one table. Create both timestamp columns like so:

create table test_table( 
  id integer not null auto_increment primary key, 
  stamp_created timestamp default '0000-00-00 00:00:00', 
  stamp_updated timestamp default now() on update now() 
); 

Note that it is necessary to enter null into both columns during insert:

mysql> insert into test_table(stamp_created, stamp_updated) values(null, null); 
Query OK, 1 row affected (0.06 sec)

mysql> select * from test_table; 
+----+---------------------+---------------------+ 
| id | stamp_created       | stamp_updated       |
+----+---------------------+---------------------+
|  2 | 2009-04-30 09:44:35 | 2009-04-30 09:44:35 |
+----+---------------------+---------------------+
2 rows in set (0.00 sec)  

mysql> update test_table set id = 3 where id = 2; 
Query OK, 1 row affected (0.05 sec) Rows matched: 1  Changed: 1  Warnings: 0  

mysql> select * from test_table;
+----+---------------------+---------------------+
| id | stamp_created       | stamp_updated       | 
+----+---------------------+---------------------+ 
|  3 | 2009-04-30 09:44:35 | 2009-04-30 09:46:59 | 
+----+---------------------+---------------------+ 
2 rows in set (0.00 sec)  

Unicode escapes only work in unicode strings, so this

 a="\u2026"

is actually a string of 6 characters: '\', 'u', '2', '0', '2', '6'.

To make unicode out of this, use decode('unicode-escape'):

a="\u2026"
print repr(a)
print repr(a.decode('unicode-escape'))

## '\\u2026'
## u'\u2026'

If you want to Iterate through the Fields and Values of a struct then you can use the below Go code as a reference.

package main

import (
    "fmt"
    "reflect"
)

type Student struct {
    Fname  string
    Lname  string
    City   string
    Mobile int64
}

func main() {
    s := Student{"Chetan", "Kumar", "Bangalore", 7777777777}
    v := reflect.ValueOf(s)
    typeOfS := v.Type()

    for i := 0; i< v.NumField(); i++ {
        fmt.Printf("Field: %s\tValue: %v\n", typeOfS.Field(i).Name, v.Field(i).Interface())
    }
}

Run in playground

Note: If the Fields in your struct are not exported then the v.Field(i).Interface() will give panic panic: reflect.Value.Interface: cannot return value obtained from unexported field or method.

In Visual Studio the default stack size is 1 MB i think, so with a recursion depth of 10,000 each stack frame can be at most ~100 bytes which should be sufficient for a DFS algorithm.

Most compilers including Visual Studio let you specify the stack size. On some (all?) linux flavours the stack size isn't part of the executable but an environment variable in the OS. You can then check the stack size with ulimit -s and set it to a new value with for example ulimit -s 16384.

Here's a link with default stack sizes for gcc.

DFS without recursion:

std::stack<Node> dfs;
dfs.push(start);
do {
    Node top = dfs.top();
    if (top is what we are looking for) {
       break;
    }
    dfs.pop();
    for (outgoing nodes from top) {
        dfs.push(outgoing node);
    }
} while (!dfs.empty())

I had the same problem that is really easy to make, but took me a while to see through.

I had copied the declaration to where I was using it and had left the 'self' argument there, but it took me ages to realise that.

I had

self.myFunction(self, a, b, c='123')

but it should have been

self.myFunction(a, b, c='123')

If you are getting the output Optional(5) when trying to print the value of 5 in an optional Int or String, you should unwrap the value first:

if let value = text {
    print(value)
}

Now you've got the value without the "Optional" string that Swift adds when the value is not unwrapped before.

You can annotate your bean with jaxb annotations.

  @XmlRootElement
  public class MyJaxbBean {
    public String name;
    public int age;

    public MyJaxbBean() {} // JAXB needs this

    public MyJaxbBean(String name, int age) {
      this.name = name;
      this.age = age;
    }
  }

and then your method would look like this:

   @GET @Produces("application/json")
   public MyJaxbBean getMyBean() {
      return new MyJaxbBean("Agamemnon", 32);
   }

There is a chapter in the latest documentation that deals with this:

https://jersey.java.net/documentation/latest/user-guide.html#json

This is an old question but you can also use express-validator package to check request params

express-validator version 4 (latest):

validator = require('express-validator/check');

app.get('/show/:id', [

    validator.param('id').isMongoId().trim()

], function(req, res) {

    // validation result
    var errors = validator.validationResult(req);

    // check if there are errors
    if ( !errors.isEmpty() ) {
        return res.send('404');
    }

    // else 
    model.findById(req.params.id, function(err, doc) { 
        return res.send(doc);
    });

});

express-validator version 3:

var expressValidator = require('express-validator');
app.use(expressValidator(middlewareOptions));

app.get('/show/:id', function(req, res, next) {

    req.checkParams('id').isMongoId();

    // validation result
    req.getValidationResult().then(function(result) {

        // check if there are errors
        if ( !result.isEmpty() ) {
            return res.send('404');
        }

        // else
        model.findById(req.params.id, function(err, doc) {
            return res.send(doc);
        });

    });

});

You'll see people using the Timer class to do this. Unfortunately, it isn't always accurate. Your best bet is to get the system time when the user enters input, calculate a target system time, and check if the system time has exceeded the target system time. If it has, then break out of the loop.

One has to create a new MySQL User and assign privileges as below in Query prompt via phpMyAdmin or command prompt:

CREATE USER 'username'@'localhost' IDENTIFIED BY 'password';

GRANT ALL PRIVILEGES ON *.* TO 'username'@'localhost' WITH GRANT OPTION;

CREATE USER 'username'@'%' IDENTIFIED BY 'password';

GRANT ALL PRIVILEGES ON *.* TO 'username'@'%' WITH GRANT OPTION;

FLUSH PRIVILEGES;

Once done with all four queries, it should connect with username / password

PHP's var_export() usually shows a serialized version of the object that can be exec()'d to re-create the object. The closest thing to that in Python is repr()

"For many types, this function makes an attempt to return a string that would yield an object with the same value when passed to eval() [...]"

Try out Following:

DataRow rows = DataTable.Select("[Name]<>'n/a'")

For Null check in This:

DataRow rows =  DataTable.Select("[Name] <> 'n/a' OR [Name] is NULL" )

I guess its clearer when you do it like this. I recommend downloading LinqPad to test things like this.

void Main()
{
    var Person = new Person(){FirstName = "Egli", LastName = "Becerra"};

    //Will update egli
    WontUpdate(Person);
    Console.WriteLine("WontUpdate");
    Console.WriteLine($"First name: {Person.FirstName}, Last name: {Person.LastName}\n");

    UpdateImplicitly(Person);
    Console.WriteLine("UpdateImplicitly");
    Console.WriteLine($"First name: {Person.FirstName}, Last name: {Person.LastName}\n");

    UpdateExplicitly(ref Person);
    Console.WriteLine("UpdateExplicitly");
    Console.WriteLine($"First name: {Person.FirstName}, Last name: {Person.LastName}\n");
}

//Class to test
public class Person{
    public string FirstName {get; set;}
    public string LastName {get; set;}

    public string printName(){
        return $"First name: {FirstName} Last name:{LastName}";
    }
}

public static void WontUpdate(Person p)
{
    //New instance does jack...
    var newP = new Person(){FirstName = p.FirstName, LastName = p.LastName};
    newP.FirstName = "Favio";
    newP.LastName = "Becerra";
}

public static void UpdateImplicitly(Person p)
{
    //Passing by reference implicitly
    p.FirstName = "Favio";
    p.LastName = "Becerra";
}

public static void UpdateExplicitly(ref Person p)
{
    //Again passing by reference explicitly (reduntant)
    p.FirstName = "Favio";
    p.LastName = "Becerra";
}

And that should output

WontUpdate

First name: Egli, Last name: Becerra

UpdateImplicitly

First name: Favio, Last name: Becerra

UpdateExplicitly

First name: Favio, Last name: Becerra

Find the ANDROID_HOME path values from environment variable. In my case it is like C:\Users\RuwanPr\AppData\Local\Android\Sdk. If this value not found please add ANDROID_HOME value as your sdk path. (To go to environment variable right click on my computer -> Properties -> Advance System Settings -> Environment Variable ) Then open cmd on windows and go to sdk folder and then go to tools folder Type emulator -list-avds in comd. It will shows avd name list. Then type emulator -avd avd-name. Ex - think avd-name shows as J2_Api_22 emulator -avd J2_Api_22

In layman terms it's strongly structured vs unstructured, which implies that you have different degrees of adaptability for your DB. Differences arise in indexation particularly as you need to ensure that a certain reference index can link to a another item -> this a relation. The more strict structure of relational DB comes from this requirement.

To note that NosDB apaprently provides both relational and non relational DBs and a way to query both http://www.alachisoft.com/nosdb/sql-cheat-sheet.html

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.

I can import with this command

docker-compose exec -T mysql mysql -uroot -proot mydatabase < ~/Desktop/mydatabase_2019-10-05.sql

Make the value a list, e.g.

a["abc"] = [1, 2, "bob"]

UPDATE:

There are a couple of ways to add values to key, and to create a list if one isn't already there. I'll show one such method in little steps.

key = "somekey"
a.setdefault(key, [])
a[key].append(1)

Results:

>>> a
{'somekey': [1]}

Next, try:

key = "somekey"
a.setdefault(key, [])
a[key].append(2)

Results:

>>> a
{'somekey': [1, 2]}

The magic of setdefault is that it initializes the value for that key if that key is not defined, otherwise it does nothing. Now, noting that setdefault returns the key you can combine these into a single line:

a.setdefault("somekey",[]).append("bob")

Results:

>>> a
{'somekey': [1, 2, 'bob']}

You should look at the dict methods, in particular the get() method, and do some experiments to get comfortable with this.

I used code like this:

  String filePath=Environment.getExternalStorageDirectory()+"/test_image.jpg";
  BitmapFactory.Options options=new BitmapFactory.Options();
  InputStream is=new FileInputStream(filePath);
  BitmapFactory.decodeStream(is, null, options);
  is.close();
  is=new FileInputStream(filePath);
  // here w and h are the desired width and height
  options.inSampleSize=Math.max(options.outWidth/460, options.outHeight/288); //Max 460 x 288 is my desired...
  // bmp is the resized bitmap
  Bitmap bmp=BitmapFactory.decodeStream(is, null, options);
  is.close();
  Log.d(Constants.TAG, "Scaled bitmap bytes, "+bmp.getRowBytes()+", width:"+bmp.getWidth()+", height:"+bmp.getHeight());

I tried original image is 1230 x 1230, and got bitmap says is 330 x 330.
And if tried 2590 x 3849, I'll got OutOfMemoryError.

I traced it, it still throw OutOfMemoryError on line "BitmapFactory.decodeStream(is, null, options);", if original bitmap too large...

You could decompose the date into it's constituent parts and then concatenate them together like this:

MsgBox(Now.Day & "/" & Now.Month & "/" & Now.Year)

Before you call setContentView(), call setTheme(android.R.style...) and just replace the ... with the theme that you want(Theme, Theme_NoTitleBar, etc.).

Or if your theme is a custom theme, then replace the entire thing, so you get setTheme(yourThemesResouceId)

Here is a nice extension I wrote...

extension Dictionary where Value: Any {
    public func mergeOnto(target: [Key: Value]?) -> [Key: Value] {
        guard let target = target else { return self }
        return self.merging(target) { current, _ in current }
    }
}

to use:

var dict1 = ["cat": 5, "dog": 6]
var dict2 = ["dog": 9, "rodent": 10]

dict1 = dict1.mergeOnto(target: dict2)

Then, dict1 will be modified to

["cat": 5, "dog": 6, "rodent": 10]

You have your ssh clone statement wrong: git clone username [email protected]:root/test.git

That statement would try to clone a repository named username into the location relative to your current path, [email protected]:root/test.git.

You want to leave out username:

git clone [email protected]:root/test.git

In my opinion using a BroadcastReceiver is a cleaner way to cancel a Notification:

In AndroidManifest.xml:

<receiver 
    android:name=.NotificationCancelReceiver" >
    <intent-filter android:priority="999" >
         <action android:name="com.example.cancel" />
    </intent-filter>
</receiver>

In java File:

Intent cancel = new Intent("com.example.cancel");
PendingIntent cancelP = PendingIntent.getBroadcast(context, 0, cancel, PendingIntent.FLAG_CANCEL_CURRENT);

NotificationCompat.Action actions[] = new NotificationCompat.Action[1];

NotificationCancelReceiver

public class NotificationCancelReceiver extends BroadcastReceiver {
    @Override
    public void onReceive(Context context, Intent intent) {
        //Cancel your ongoing Notification
    };
}

I would omit the * { text-align:center } declaration, as it sets center alignment for all elements.

Usually with a fixed width container margin: 0 auto should be enough

Simply restarting Visual Studio worked for me.

Almost all of these have issues when the user tries to backspace over the delimiters, particularly from the middle of the string.

Here's a jquery solution that handles that, and also makes sure the cursor stays in the right place as you edit:

//format text input as phone number (nnn) nnn-nnnn
$('.myPhoneField').on('input', function (e){
    var $phoneField = e.target;
    var cursorPosition = $phoneField.selectionStart;
    var numericString = $phoneField.value.replace(/\D/g, '').substring(0, 10);

    // let user backspace over the '-'
    if (cursorPosition === 9 && numericString.length > 6) return;

    // let user backspace over the ') '
    if (cursorPosition === 5 && numericString.length > 3) return;
    if (cursorPosition === 4 && numericString.length > 3) return;

    var match = numericString.match(/^(\d{1,3})(\d{0,3})(\d{0,4})$/);
    if (match) {
        var newVal = '(' + match[1];
        newVal += match[2] ? ') ' + match[2] : '';
        newVal += match[3] ? '-' + match[3] : '';

        // to help us put the cursor back in the right place
        var delta = newVal.length - Math.min($phoneField.value.length, 14);      
        $phoneField.value = newVal;
        $phoneField.selectionEnd = cursorPosition + delta;
    } else {
        $phoneField.value = '';        
    }
})

As pointed out by Ryan above, the command you need is

GRANT ALL ON *.* to user@'%' IDENTIFIED BY 'password'; 

However, note that the documentation indicates that in order for this to work, another user account from localhost must be created for the same user; otherwise, the anonymous account created automatically by mysql_install_db takes precedence because it has a more specific host column.

In other words; in order for user user to be able to connect from any server; 2 accounts need to be created as follows:

GRANT ALL ON *.* to user@localhost IDENTIFIED BY 'password'; 
GRANT ALL ON *.* to user@'%' IDENTIFIED BY 'password'; 

Read the full documentation here.

And here's the relevant piece for reference:

After connecting to the server as root, you can add new accounts. The following statements use GRANT to set up four new accounts:

mysql> CREATE USER 'monty'@'localhost' IDENTIFIED BY 'some_pass';
mysql> GRANT ALL PRIVILEGES ON *.* TO 'monty'@'localhost'
    ->     WITH GRANT OPTION;
mysql> CREATE USER 'monty'@'%' IDENTIFIED BY 'some_pass';
mysql> GRANT ALL PRIVILEGES ON *.* TO 'monty'@'%'
    ->     WITH GRANT OPTION;
mysql> CREATE USER 'admin'@'localhost';
mysql> GRANT RELOAD,PROCESS ON *.* TO 'admin'@'localhost';
mysql> CREATE USER 'dummy'@'localhost';

The accounts created by these statements have the following properties:

Two of the accounts have a user name of monty and a password of some_pass. Both accounts are superuser accounts with full privileges to do anything. The 'monty'@'localhost' account can be used only when connecting from the local host. The 'monty'@'%' account uses the '%' wildcard for the host part, so it can be used to connect from any host.

It is necessary to have both accounts for monty to be able to connect from anywhere as monty. Without the localhost account, the anonymous-user account for localhost that is created by mysql_install_db would take precedence when monty connects from the local host. As a result, monty would be treated as an anonymous user. The reason for this is that the anonymous-user account has a more specific Host column value than the 'monty'@'%' account and thus comes earlier in the user table sort order. (user table sorting is discussed in Section 6.2.4, “Access Control, Stage 1: Connection Verification”.)

<xsl:variable name="count" select="count(/Property/long = $parPropId)"/>

Un-tested but I think that should work. I'm assuming the Property nodes are direct children of the root node and therefor taking out your descendant selector for peformance

There are not many good reasons this would fail, especially the regsvr32 step. Run dumpbin /exports on that dll. If you don't see DllRegisterServer then you've got a corrupt install. It should have more side-effects, you wouldn't be able to build C/C++ projects anymore.

One standard failure mode is running this on a 64-bit operating system. This is 32-bit unmanaged code, you would indeed get the 'class not registered' exception. Project + Properties, Build tab, change Platform Target to x86.

You can use javascript to block form submission until the appropriate time. A very crude example:

<form onsubmit='return false;' id='frmNoEnterSubmit' action="index.html">

    <input type='text' name='txtTest' />

    <input type='button' value='Submit' 
        onclick='document.forms["frmNoEnterSubmit"].onsubmit=""; document.forms["frmNoEnterSubmit"].submit();' />

</form>

Pressing enter will still trigger the form to submit, but the javascript will keep it from actually submitting, until you actually press the button.

The argument of func is accepting double-pointer variable. Hope this helps...

#include <stdio.h>

int func(int **B){

}

int main(void){

    int *B[10];

    func(B);

    return 0;
}

You can right-click on your project then Maven > Update Project..., then select Force Update of Snapshots/Releases checkbox then click OK.

If you want to delete all of the data in Solr via SolrJ do something like this.

public static void deleteAllSolrData() {
    HttpSolrServer solr = new HttpSolrServer("http://localhost:8080/solr/core/");
    try {
      solr.deleteByQuery("*:*");
    } catch (SolrServerException e) {
      throw new RuntimeException("Failed to delete data in Solr. "
          + e.getMessage(), e);
    } catch (IOException e) {
      throw new RuntimeException("Failed to delete data in Solr. "
          + e.getMessage(), e);
    }
}

If you want to delete all of the data in HBase do something like this.

public static void deleteHBaseTable(String tableName, Configuration conf) {
    HBaseAdmin admin = null;    
    try {
        admin = new HBaseAdmin(conf);
        admin.disableTable(tableName);
        admin.deleteTable(tableName);
    } catch (MasterNotRunningException e) {
        throw new RuntimeException("Unable to delete the table " + tableName
        + ". The actual exception is: " + e.getMessage(), e);
    } catch (ZooKeeperConnectionException e) {
        throw new RuntimeException("Unable to delete the table " + tableName
        + ". The actual exception is: " + e.getMessage(), e);
    } catch (IOException e) {
        throw new RuntimeException("Unable to delete the table " + tableName
        + ". The actual exception is: " + e.getMessage(), e);
    } finally {
        close(admin);
    }
 }

It's a very bad idea to directly display any text on an irregular and ever changing background. No matter what you do, some of the time the text will be hard to read.

The best design would be to have the labels on a constant background with the images changing behind that.

You can set the labels background color from clear to white and set the from alpha to 50.0 you get a nice translucent effect. The only problem is that the label's background is a stark rectangle.

To get a label with a background with rounded corners you can use a button with user interaction disabled but the user might mistake that for a button.

The best method would be to create image of the label background you want and then put that in an imageview and put the label with the default transparent background onto of that.

Plain UIViews do not have an image background. Instead, you should make a UIImageView your main view and then rotate the images though its image property. If you set the UIImageView's mode to "Scale to fit" it will scale any image to fit the bounds of the view.

eg:

// .vscode/settings.json in workspace

{
  "files.associations": {
    "*Container.js": "javascriptreact",
    "**/components/*/*.js": "javascriptreact",
    "**/config/routes.js": "javascriptreact"
  }
}

CLR, BCL and C#/VB.Net, ADO.NET, WinForms and/or ASP.NET. Most of the places that require additional .Net technologies, like WPF or WCF will call it out explicitly.

In my case, when I run df -i it shows me that my number of inodes are full and then I have to delete some of the small files or folder. Otherwise it will not allow us to create files or folders once inodes get full.

All you have to do is delete files or folder that has not taken up full space but is responsible for filling inodes.

Last-Modified : The last modified date for the requested object

If-Modified-Since : Allows a 304 Not Modified to be returned if last modified date is unchanged.

ETag : An ETag is an opaque identifier assigned by a web server to a specific version of a resource found at a URL. If the resource representation at that URL ever changes, a new and different ETag is assigned.

If-None-Match : Allows a 304 Not Modified to be returned if ETag is unchanged.

the browser store cache with a date(Last-Modified) or id(ETag), when you need to request the URL again, the browser send request message with the header:

the server will return 304 when the if statement is False, and browser will use cache.

I got a similar problem.

If I power on my Arduino, there is a delay before the uploaded program execute.

So I use that delay for uploading new program, or empty program:

void setup(){}

void loop(){}

So my problem was solved.

Unplug any connection to Arduino pins before upload.

The above methods seem to be complex. Use my method as a reference.

I have these two files:

• run.php

• mkdir.py

Here, I've created an HTML page which contains a GO button. Whenever you press this button a new folder will be created in directory whose path you have mentioned.

os.makedirs("thisfolder");

I'm surprised there's been no mention of filter_var here for this being such an old question...

PHP has a built in method of doing this using sanitization filters. Specifically, the one to use in this situation is FILTER_SANITIZE_NUMBER_FLOAT with the FILTER_FLAG_ALLOW_FRACTION | FILTER_FLAG_ALLOW_THOUSAND flags. Like so:

$numeric_filtered = filter_var("AR3,373.31", FILTER_SANITIZE_NUMBER_FLOAT,
    FILTER_FLAG_ALLOW_FRACTION | FILTER_FLAG_ALLOW_THOUSAND);
echo $numeric_filtered; // Will print "3,373.31"

It might also be worthwhile to note that because it's built-in to PHP, it's slightly faster than using regex with PHP's current libraries (albeit literally in nanoseconds).

With Gson, you'd just need to do something like:

List<Video> videos = gson.fromJson(json, new TypeToken<List<Video>>(){}.getType());

You might also need to provide a no-arg constructor on the Video class you're deserializing to.

Both map and flatMap can be applied to a Stream<T> and they both return a Stream<R>. The difference is that the map operation produces one output value for each input value, whereas the flatMap operation produces an arbitrary number (zero or more) values for each input value.

This is reflected in the arguments to each operation.

The map operation takes a Function, which is called for each value in the input stream and produces one result value, which is sent to the output stream.

The flatMap operation takes a function that conceptually wants to consume one value and produce an arbitrary number of values. However, in Java, it's cumbersome for a method to return an arbitrary number of values, since methods can return only zero or one value. One could imagine an API where the mapper function for flatMap takes a value and returns an array or a List of values, which are then sent to the output. Given that this is the streams library, a particularly apt way to represent an arbitrary number of return values is for the mapper function itself to return a stream! The values from the stream returned by the mapper are drained from the stream and are passed to the output stream. The "clumps" of values returned by each call to the mapper function are not distinguished at all in the output stream, thus the output is said to have been "flattened."

Typical use is for the mapper function of flatMap to return Stream.empty() if it wants to send zero values, or something like Stream.of(a, b, c) if it wants to return several values. But of course any stream can be returned.

Just looking at the message it sounds like one or more of the components that you reference, or one or more of their dependencies is not registered properly.

If you know which component it is you can use regsvr32.exe to register it, just open a command prompt, go to the directory where the component is and type regsvr32 filename.dll (assuming it's a dll), if it works, try to run the code again otherwise come back here with the error.

If you don't know which component it is, try re-installing/repairing the GIS software (I assume you've installed some GIS software that includes the component you're trying to use).

You can enclose it in quotes, if you supply a dummy first argument.

Note that you need to supply a dummy first argument in this case, as start will treat the first argument as a title for the new console windows, if it is quoted. So the following should work (and does here):

start "" "http://www.google.com/search?client=opera&rls=en&q=escape+ampersand&sourceid=opera&ie=utf-8&oe=utf-8"

Always try to use interface reference in Collection, this adds more flexibility.
What is the problem with the below code?

List<Map<String,List<String>>> list = new ArrayList<Map<String,List<String>>>();//This is the final list you need
Map<String, List<String>> map1 = new HashMap<String, List<String>>();//This is one instance of the  map you want to store in the above list.
List<String> arraylist1 = new ArrayList<String>();
arraylist1.add("Text1");//And so on..
map1.put("key1",arraylist1);
//And so on...
list.add(map1);//In this way you can add.

You can easily do it like the above.

Installing Aptana Studio in passive mode bypasses the installation of Git for Windows and Node.js.

Aptana_Studio_3_Setup_3.6.1 /passive /norestart

(I am unsure whether Aptana Studio will work properly without those "prerequisites", but it appears to.)

If you want a global installation in a specific directory, the command line is

Aptana_Studio_3_Setup_3.6.1.exe /passive /norestart ALLUSERS=1 APPDIR=c:\apps\AptanaStudio

It's "kind of" possible through using gdb and setenv(3), although I have a hard time recommending actually doing this. (Additionally, i.e. the most recent ubuntu won't actually let you do this without telling the kernel to be more permissive about ptrace, and the same may go for other distros as well).

$ cat setfoo
#! /bin/bash

gdb /proc/${PPID}/exe ${PPID} <<END >/dev/null
call setenv("foo", "bar", 0)
END
$ echo $foo

$ ./setfoo
$ echo $foo
bar

How about using the following:

mylist = [1, 2, 3, 4, 5, 6, 7]

def sliding_window(l, window_size=2):
    if window_size > len(l):
        raise ValueError("Window size must be smaller or equal to the number of elements in the list.")

    t = []
    for i in xrange(0, window_size):
        t.append(l[i:])

    return zip(*t)

print sliding_window(mylist, 3)

Output:

[(1, 2, 3), (2, 3, 4), (3, 4, 5), (4, 5, 6), (5, 6, 7)]

As slight improvement to @MONTYHS answer, iterating through a tup of fieldnames:

import csv
import json

csvfilename = 'filename.csv'
jsonfilename = csvfilename.split('.')[0] + '.json'
csvfile = open(csvfilename, 'r')
jsonfile = open(jsonfilename, 'w')
reader = csv.DictReader(csvfile)

fieldnames = ('FirstName', 'LastName', 'IDNumber', 'Message')

output = []

for each in reader:
  row = {}
  for field in fieldnames:
    row[field] = each[field]
output.append(row)

json.dump(output, jsonfile, indent=2, sort_keys=True)

This still loops through the cartesian product of the two lists, but it does it one line:

>>> lines1 = ['soup', 'butter', 'venison']
>>> lines2 = ['prune', 'rye', 'turkey']
>>> search_strings = ['a', 'b', 'c']
>>> any(s in l for l in lines1 for s in search_strings)
True
>>> any(s in l for l in lines2 for s in search_strings)
False

This also have the advantage that any short-circuits, and so the looping stops as soon as a match is found. Also, this only finds the first occurrence of a string from search_strings in linesX. If you want to find multiple occurrences you could do something like this:

>>> lines3 = ['corn', 'butter', 'apples']
>>> [(s, l) for l in lines3 for s in search_strings if s in l]
[('c', 'corn'), ('b', 'butter'), ('a', 'apples')]

If you feel like coding something more complex, it seems the Aho-Corasick algorithm can test for the presence of multiple substrings in a given input string. (Thanks to Niklas B. for pointing that out.) I still think it would result in quadratic performance for your use-case since you'll still have to call it multiple times to search multiple lines. However, it would beat the above (cubic, on average) algorithm.

try this

if($('input:radio:checked').length > 0){
// go on with script
 }else{
    // NOTHING IS CHECKED
 }

I recommend using tables with <td valign="middle"> (as inkedmn mentioned, it works in all browsers), but if you're wrapping with a link, here's how to do it (works in ugly old browsers too, like Opera 9):

<a href="/" style="display: block; vertical-align: middle;">
    <img src="/logo.png" style="vertical-align: middle;"/>
    <span style="vertical-align: middle;">Sample text</span>
</a>

Expanding upon Gustavo Lima's answer. The same thing can be done without creating an entirely new list. The values in the list can be replaced with the differentials as the FOR loop progresses.

def f_ClosestVal(v_List, v_Number):
"""Takes an unsorted LIST of INTs and RETURNS INDEX of value closest to an INT"""
for _index, i in enumerate(v_List):
    v_List[_index] = abs(v_Number - i)
return v_List.index(min(v_List))

myList = [1, 88, 44, 4, 4, -2, 3]
v_Num = 5
print(f_ClosestVal(myList, v_Num)) ## Gives "3," the index of the first "4" in the list.

Restarting Testing device fix the issue for me.

Tried all the above approaches, didn't work. Finally running maven clean install solved it!

If possible, use stored statements to avoid the inefficiency of both indexes on RND() and creating a record number field.

PREPARE RandomRecord FROM "SELECT * FROM table LIMIT ?,1";
SET @n=FLOOR(RAND()*(SELECT COUNT(*) FROM table));
EXECUTE RandomRecord USING @n;

git push public :master

This would delete the remote branch named master as Kent Fredric has pointed out.

To list remote-tracking branches:

git branch -r

To delete a remote-tracking branch:

git branch -rd public/master

You can use .on() to bind a function to multiple events:

$('#element').on('keyup keypress blur change', function(e) {
    // e.type is the type of event fired
});

Or just pass the function as the parameter to normal event functions:

var myFunction = function() {
   ...
}

$('#element')
    .keyup(myFunction)
    .keypress(myFunction)
    .blur(myFunction)
    .change(myFunction)

The length of the array is 7, the NUL character \0 still counts as a character and the string is still terminated with an implicit \0

See this link to see a working example

Note that had you declared str as char str[6]= "Hello\0"; the length would be 6 because the implicit NUL is only added if it can fit (which it can't in this example.)

§ 6.7.8/p14
An array of character type may be initialized by a character string literal, optionally enclosed in braces. Sucessive characters of the character string literal (including the terminating null character if there is room or if the array is of unknown size) initialize the elements of the array.

Examples

char str[] = "Hello\0"; /* sizeof == 7, Explicit + Implicit NUL */
char str[5]= "Hello\0"; /* sizeof == 5, str is "Hello" with no NUL (no longer a C-string, just an array of char). This may trigger compiler warning */
char str[6]= "Hello\0"; /* sizeof == 6, Explicit NUL only */
char str[7]= "Hello\0"; /* sizeof == 7, Explicit + Implicit NUL */
char str[8]= "Hello\0"; /* sizeof == 8, Explicit + two Implicit NUL */

A break will allow you continue processing in the function. Just returning out of the switch is fine if that's all you want to do in the function.

I use GNU Cash and it uses Open Financial Exchange (ofx) http://www.ofx.net/ to download complete transactions and balances from each account of each bank.

Let me emphasize that again, you get a huge list of transactions with OFX into the GNU Cash. Depending on the account type these transactions can be very detailed description of your transactions (purchases+paycheques), investments, interests, etc.

In my case, even though I have Chase debit card I had to choose Chase Credit to make it work. But Chase wants you to enable this OFX feature by logging into your online banking and enable Quicken/MS Money/etc. somewhere in your profile or preferences. Don't call Chase customer support because they know nothing about it.

This service for OFX and GNU Cash is free. I have heard that they charge $10 a month for other platforms.

OFX can download transactions from 348 banks so far. http://www.ofxhome.com/index.php/home/directory

Actualy, OFX also supports making bill payments, stop a check, intrabank and interbank transfers etc. It is quite extensive. See it here: http://ofx.net/AboutOFX/ServicesSupported.aspx

Open Terminal and execute commands given below.

cd /etc
subl bashrc

subl denotes Sublime editor. You can replace subl with vi to open bashrc file in default editor. This will workout only if you have bashrc file, created earlier.

A library performs specific, well-defined operations.

A framework is a skeleton where the application defines the "meat" of the operation by filling out the skeleton. The skeleton still has code to link up the parts but the most important work is done by the application.

Examples of libraries: Network protocols, compression, image manipulation, string utilities, regular expression evaluation, math. Operations are self-contained.

Examples of frameworks: Web application system, Plug-in manager, GUI system. The framework defines the concept but the application defines the fundamental functionality that end-users care about.

From String literals:

• raw string literal supports multiline (but escaped characters aren't interpreted)
• interpreted string literal interpret escaped characters, like '\n'.

But, if your multi-line string has to include a backquote (`), then you will have to use an interpreted string literal:

`line one
  line two ` +
"`" + `line three
line four`

You cannot directly put a backquote (`) in a raw string literal (``xx\).
You have to use (as explained in "how to put a backquote in a backquoted string?"):

 + "`" + ...

These commands worked for Artik 10 :

• cat /etc/fedora-release
• cat /etc/issue
• hostnamectl

and these others didn't :

• lsb_release -a
• uname -a

You use the cherry-pick command to get individual commits from one branch.

If the change(s) you want are not in individual commits, then use the method shown here to split the commit into individual commits. Roughly speaking, you use git rebase -i to get the original commit to edit, then git reset HEAD^ to selectively revert changes, then git commit to commit that bit as a new commit in the history.

There is another nice method here in Red Hat Magazine, where they use git add --patch or possibly git add --interactive which allows you to add just parts of a hunk, if you want to split different changes to an individual file (search in that page for "split").

Having split the changes, you can now cherry-pick just the ones you want.

You can also move mounted out of the Vue instance and make it a function in the top-level scope. This is also a useful trick for server side rendering in Vue.

function init() {
  // Use `this` normally
}

new Vue({
  methods:{
    init
  },
  mounted(){
    init.call(this)
  }
})

All of

std::string s(1, c); std::cout << s << std::endl;

and

std::cout << std::string(1, c) << std::endl;

and

std::string s; s.push_back(c); std::cout << s << std::endl;

worked for me.

You can use the lock statement instead. I think this can only replace the second version. Also, remember that both synchronized and lock need to operate on an object.

Sorry to post answer for very old thread. my answer may help other in future.

string[] TobeDistinct = {"Name","City","State"};
DataTable dtDistinct = GetDistinctRecords(DTwithDuplicate, TobeDistinct);

    //Following function will return Distinct records for Name, City and State column.
    public static DataTable GetDistinctRecords(DataTable dt, string[] Columns)
       {
           DataTable dtUniqRecords = new DataTable();
           dtUniqRecords = dt.DefaultView.ToTable(true, Columns);
           return dtUniqRecords;
       }

The method works if you provide an array. The output of

String[] helloWorld = {"Hello", "World"};
System.out.println(helloWorld);
System.out.println(Arrays.toString(helloWorld));

is

[Ljava.lang.String;@45a877
[Hello, World]

(the number after @ is almost always different)

If you want to use all stylesheet in your app just adds this line in application.html.erb. Insert it inside <head> tag

  <%= stylesheet_link_tag  controller.controller_name , media: 'all', 'data-turbolinks-track': 'reload' %>

Also, to specify the same class CSS on a different controller
Add this line in the body of application.html.erb

  <body class="<%= controller.controller_name %>-<%= controller.action_name %>">

So, now for example I would like to change the p tag in 'home' controller and 'index' action. Inside index.scss file adds.

.nameOfController-nameOfAction <tag> { }

 .home-index p {
        color:red !important;
      }

The only reason that the linter complains about using setState({..}) in componentDidMount and componentDidUpdate is that when the component render the setState immediately causes the component to re-render. But the most important thing to note: using it inside these component's lifecycles is not an anti-pattern in React.

Please take a look at this issue. you will understand more about this topic. Thanks for reading my answer.

As others have mentioned, try stopPropagation().

And there is a second handler to try: event.cancelBubble = true; It's a IE specific handler, but it is supported in at least FF. Don't really know much about it, as I haven't used it myself, but it might be worth a shot, if all else fails.

I started Eclipse as admin, and it worked.

$(":input#single").trigger('change');

This worked for my script. I have 3 combos & bind with chainSelect event, I need to pass 3 values by url & default select all drop down. I used this

$('#machineMake').val('<?php echo $_GET['headMake']; ?>').trigger('change');

And the first event worked.

Combine them. Literally combine them; attach them together without any punctuation.

$('.myclass[reference="12345"]')

Your first selector looks for elements with the attribute value, contained in elements with the class.
The space is being interpreted as the descendant selector.

Your second selector, like you said, looks for elements with either the attribute value, or the class, or both.
The comma is being interpreted as the multiple selector operator — whatever that means (CSS selectors don't have a notion of "operators"; the comma is probably more accurately known as a delimiter).

My approach:

• define a default constraint on the ModDate column with a value of GETDATE() - this handles the INSERT case

• have a AFTER UPDATE trigger to update the ModDate column

Something like:

CREATE TRIGGER trg_UpdateTimeEntry
ON dbo.TimeEntry
AFTER UPDATE
AS
    UPDATE dbo.TimeEntry
    SET ModDate = GETDATE()
    WHERE ID IN (SELECT DISTINCT ID FROM Inserted)

About your command line:

root@debian:/# sudo iptables -A INPUT -p tcp --dport 3306 --jump ACCEPT
root@debian:/# iptables-save

• You are already authenticated as root so sudo is redundant there.

• You are missing the -j or --jump just before the ACCEPT parameter (just tought that was a typo and you are inserting it correctly).

About yout question:

If you are inserting the iptables rule correctly as you pointed it in the question, maybe the issue is related to the hypervisor (virtual machine provider) you are using.

If you provide the hypervisor name (VirtualBox, VMWare?) I can further guide you on this but here are some suggestions you can try first:

check your vmachine network settings and:

• if it is set to NAT, then you won't be able to connect from your base machine to the vmachine.

• if it is set to Hosted, you have to configure first its network settings, it is usually to provide them an IP in the range 192.168.56.0/24, since is the default the hypervisors use for this.

• if it is set to Bridge, same as Hosted but you can configure it whenever IP range makes sense for you configuration.

Hope this helps.

I can't get it to work on $.get() because it has no complete event.

I suggest to use $.ajax() like this,

$.ajax({

    data: {'a':1,'b':2,'c':3},
    dataType: 'xml',
    complete : function(){
        alert(this.url)
    },
    success: function(xml){
    }
});

You can use a bit of functionality that is already built in to the ant jar task.

If you go to The documentation for the ant jar task and scroll down to the "merging archives" section there's a snippet for including the all the *.class files from all the jars in you "lib/main" directory:

<jar destfile="build/main/checksites.jar">
    <fileset dir="build/main/classes"/>
    <restrict>
        <name name="**/*.class"/>
        <archives>
            <zips>
                <fileset dir="lib/main" includes="**/*.jar"/>

    </restrict>
    <manifest>
      <attribute name="Main-Class" value="com.acme.checksites.Main"/>

This Creates an executable jar file with a main class "com.acme.checksites.Main", and embeds all the classes from all the jars in lib/main.

It won't do anything clever in case of namespace conflicts, duplicates and things like that. Also, it will include all class files, also the ones that you don't use, so the combined jar file will be full size.

If you need more advanced things like that, take a look at like one-jar and jar jar links

If your Dialog is creating on the adapter:

Pass the Activity to the Adapter Constructor:

adapter = new MyAdapter(getActivity(),data);

Receive on the Adapter:

 public MyAdapter(Activity activity, List<Data> dataList){
       this.activity = activity;
    }

Now you can use on your Builder

            AlertDialog.Builder alert = new AlertDialog.Builder(activity);

There is no way to get the logs for installing problems.

To track each try this example and before that completely reduce cursor blink rate to zero.

onblur : event generates on exit

onchange : event generates on exit if any changes made in inputtext

onkeydown: event generates on any key press (for key holding long times also)

onkeyup : event generates on any key release

onkeypress: same as onkeydown (or onkeyup) but won't react for ctrl,backsace,alt other

Optimized (but less readable) implementation:

function base64toBlob(base64Data, contentType) {
    contentType = contentType || '';
    var sliceSize = 1024;
    var byteCharacters = atob(base64Data);
    var bytesLength = byteCharacters.length;
    var slicesCount = Math.ceil(bytesLength / sliceSize);
    var byteArrays = new Array(slicesCount);

    for (var sliceIndex = 0; sliceIndex < slicesCount; ++sliceIndex) {
        var begin = sliceIndex * sliceSize;
        var end = Math.min(begin + sliceSize, bytesLength);

        var bytes = new Array(end - begin);
        for (var offset = begin, i = 0; offset < end; ++i, ++offset) {
            bytes[i] = byteCharacters[offset].charCodeAt(0);
        }
        byteArrays[sliceIndex] = new Uint8Array(bytes);
    }
    return new Blob(byteArrays, { type: contentType });
}

$("[id$='" + originalId + "']").val("0 index value");

will set it to 0

Generally, I see continue (and break) as a warning that the code might use some refactoring, especially if the while or for loop declaration isn't immediately in sight. The same is true for return in the middle of a method, but for a slightly different reason.

As others have already said, continue moves along to the next iteration of the loop, while break moves out of the enclosing loop.

These can be maintenance timebombs because there is no immediate link between the continue/break and the loop it is continuing/breaking other than context; add an inner loop or move the "guts" of the loop into a separate method and you have a hidden effect of the continue/break failing.

IMHO, it's best to use them as a measure of last resort, and then to make sure their use is grouped together tightly at the start or end of the loop so that the next developer can see the "bounds" of the loop in one screen.

continue, break, and return (other than the One True Return at the end of your method) all fall into the general category of "hidden GOTOs". They place loop and function control in unexpected places, which then eventually causes bugs.

This is my LDAP Java login test application supporting LDAP:// and LDAPS:// self-signed test certificate. Code is taken from few SO posts, simplified implementation and removed legacy sun.java.* imports.

• how to accept self-signed certificates for JNDI/LDAP connections?
• Authenticating against Active Directory with Java on Linux

Usage
I have run this in Windows7 and Linux machines against WinAD directory service. Application prints username and member groups.

$ java -cp classes test.LoginLDAP url=ldap://1.2.3.4:389 [email protected] password=mypwd

$ java -cp classes test.LoginLDAP url=ldaps://1.2.3.4:636 [email protected] password=mypwd

Test application supports temporary self-signed test certificates for ldaps:// protocol, this DummySSLFactory accepts any server cert so man-in-the-middle is possible. Real life installation should import server certificate to a local JKS keystore file and not using dummy factory.

Application uses enduser's username+password for initial context and ldap queries, it works for WinAD but don't know if can be used for all ldap server implementations. You could create context with internal username+pwd then run queries to see if given enduser is found.

Instead of using the new pragmas, you can also use __attribute__((optimize("O0"))) for your needs. This has the advantage of just applying to a single function and not all functions defined in the same file.

Usage example:

void __attribute__((optimize("O0"))) foo(unsigned char data) {
    // unmodifiable compiler code
}

If the anonymous type causes trouble for you, you can create a simple data class:

public class PermissionsAndPages
{
     public ObjectPermissions Permissions {get;set}
     public Pages Pages {get;set}
}

and then in your query:

select new PermissionsAndPages { Permissions = op, Page = pg };

Then you can pass this around:

return queryResult.SingleOrDefault(); // as PermissionsAndPages

The JSON sample you provided is not valid. Check it online with this JSON Validator http://jsonlint.com/. You need to remove the extra comma on line 59.

One you have valid json you can use this code to convert it to an array.

Once you have done your processing in the selectFunction() you could do the following

document.getElementById('select').value = 'Default';

I had this problem with MinGW (actually Git Bash) running on a Windows Server. None of the above suggestions seemed to work. In the end a made a copy of the directory in case then deleted the soft link in Windows Explorer then deleted the item in the Recycle Bin. It made noises like it was deleting the files but didn't. Do make a backup though!

If you are using Dot.Net then the code you need is

Environment.GetFolderPath(Environment.SpecialFolder.InternetCache)

Click my name if you want the code to delete these files plus FireFox temp files and Flash shared object/Flash Cookies

Copy-paste the following into your current terminal:

gsettings set org.gnome.desktop.default-applications.terminal exec /usr/bin/terminator
gsettings set org.gnome.desktop.default-applications.terminal exec-arg "-x"

This modifies the dconf to make terminator the default program. You could also use dconf-editor (a GUI-based tool) to make changes to the dconf, as another answer has suggested. If you would like to learn and understand more about this topic, this may help you.

if user find particular array elements then use below code same as integer value.

var arrelemnts = ["sachin", "test", "test1", "test3"]

 if arrelemnts.contains("test"){
    print("found")   }else{
    print("not found")   }

Try This

/^(19[0-9]{2}|2[0-9]{3})\-(0[1-9]|1[0-2])\-(0[1-9]|1[0-9]|2[0-9]|3[0-1])((T|\s)(0[0-9]{1}|1[0-9]{1}|2[0-3]{1})\:(0[0-9]{1}|1[0-9]{1}|2[0-9]{1}|3[0-9]{1}|4[0-9]{1}|5[0-9]{1})\:(0[0-9]{1}|1[0-9]{1}|2[0-9]{1}|3[0-9]{1}|4[0-9]{1}|5[0-9]{1})((\+|\.)[\d+]{4,8})?)?$/

this regular expression valid for :

• 2017-01-01T00:00:00+0000
• 2017-01-01 00:00:00+00:00

• 2017-01-01 00:00:00+0000
• 2017-01-01

Remember that this will be cover all case of date and date time with (-) character

I have another way to do this if you're using Nuget to manage your dependencies. I've discovered that sometimes VS and Nuget don't match up and Nuget is unable to recognize that your projects are out of sync. The packages.config will say one thing but the path shown in References - Properties will indicate something else.

If you're willing to update your dependencies, do the following:

1. From Solution Explorer, right click the Project and click 'Manage Nuget Packages'

2. Select 'Installed packages' tab in left pane Record your installed packages You may want to copy your packages.config to your desktop first if you have a lot, so you can cross check it with Google to see what Nuget pkgs are installed

3. Uninstall your packages. Its OK, we're going to add them right back.

4. Immediately install the packages you need. What Nuget will do is not only get you the latest version, but will alter your references, and also add the binding redirects for you.

5. Do this for all of your projects.

6. At the solution level, do a Clean and Rebuild.

You may want to start with the lower projects and work your way to the higher level ones, and rebuild each project as you go along.

If you don't want to update your dependencies, then you can use the package manager console, and use the syntax Update-Package -ProjectName [yourProjectName] [packageName] -Version [versionNumber]

Early support for storing JSON in MySQL has been added to the MySQL 5.7.7 JSON labs release (linux binaries, source)! The release seems to have grown from a series of JSON-related user-defined functions made public back in 2013.

This nascent native JSON support seems to be heading in a very positive direction, including JSON validation on INSERT, an optimized binary storage format including a lookup table in the preamble that allows the JSN_EXTRACT function to perform binary lookups rather than parsing on every access. There is also a whole raft of new functions for handling and querying specific JSON datatypes:

CREATE TABLE users (id INT, preferences JSON);

INSERT INTO users VALUES (1, JSN_OBJECT('showSideBar', true, 'fontSize', 12));

SELECT JSN_EXTRACT(preferences, '$.showSideBar') from users;

+--------------------------------------------------+
| id   | JSN_EXTRACT(preferences, '$.showSideBar') |
+--------------------------------------------------+
| 1    | true                                      |
+--------------------------------------------------+

IMHO, the above is a great use case for this new functionality; many SQL databases already have a user table and, rather than making endless schema changes to accommodate an evolving set of user preferences, having a single JSON column a single JOIN away is perfect. Especially as it's unlikely that it would ever need to be queried for individual items.

While it's still early days, the MySQL server team are doing a great job of communicating the changes on the blog.

For ad hoc queries, the ODBC Test utility is pretty handy. Its design and interface is more oriented toward testing various parts of the ODBC API. But it works quite nicely for running queries and showing the output. It is part of the Microsoft Data Access Components.

To run a query, you can click the connect button (or use ctrl-F), choose a data source, type a query, then ctrl-E to execute it and ctrl-R to display the results (e.g., if it is a SELECT or something that returns a cursor).
