You have a CryptoListPresenter _presenter but you are never initializing it. You should either be doing that when you declare it or in your initState() (or another appropriate but called-before-you-need-it method).

One thing I find that helps is that if I know a member is functionally 'final', to actually set it to final as that way the analyzer complains that it hasn't been initialized.

EDIT:

I see diegoveloper beat me to answering this, and that the OP asked a follow up.

@Jake - it's hard for us to tell without knowing exactly what CryptoListPresenter is, but depending on what exactly CryptoListPresenter actually is, generally you'd do final CryptoListPresenter _presenter = new CryptoListPresenter(...);, or

CryptoListPresenter _presenter;

@override
void initState() {
  _presenter = new CryptoListPresenter(...);
}

For me the solution was to correct the order:

app.UseCors();
app.UseAuthentication();
app.UseAuthorization();

step 1. sudo mysql -u root -p

step 2. USE mysql;

step 3. ALTER USER 'root'@'localhost' IDENTIFIED WITH mysql_native_password BY 'admin';

Here 'admin' is your new password, yo can change it.

step 4. exit

Thanks. You are done.

On Debian 9 I had to:

$ sudo update-ca-certificates --fresh
$ export SSL_CERT_DIR=/etc/ssl/certs

I'm not sure why, but this enviroment variable was never set.

Select the project. Properties->Configuration Properties->Linker->System.

My problem solved by setting below option. Under System: SubSystem = Console(/SUBSYSTEM:CONSOLE)

Or you can choose the last option as "inherite from the parent".

The CGRectZero constant is equal to a rectangle at position (0,0) with zero width and height. This is fine to use, and actually preferred, if you use AutoLayout, since AutoLayout will then properly place the view.

But, I expect you do not use AutoLayout. So the most simple solution is to specify the size of the custom view by providing a frame explicitly:

customView = MyCustomView(frame: CGRect(x: 0, y: 0, width: 200, height: 50))
self.view.addSubview(customView)

Note that you also need to use addSubview otherwise your view is not added to the view hierarchy.

You can simplify your code down to

url = "http://worldcup.kimonolabs.com/api/players?apikey=xxx"
json_obj = urllib2.urlopen(url).read
player_json_list = json.loads(json_obj)
for player in readable_json_list:
    print player['firstName']

You were trying to access a list element using dictionary syntax. the equivalent of

foo = [1, 2, 3, 4]
foo["1"]

It can be confusing when you have lists of dictionaries and keeping the nesting in order.

Finally I found a mistake! Hope this is useful to someone. When doing a request to the database(in my case it Apache Derby), name of base need write the first letter upper case other in lower case.

This is wrong query:

session.createQuery("select first_name from CUSTOMERV").

This is valid query

session.createQuery("select first_name from Customerv"). 

And class entity must be same name as database, but I'm not sure.

This is not a question about make, it is a question about the semantic of the #include directive.

The problem is, that there is no file at the path "../StdCUtil/StdCUtil/split.h". This is the path that results when the compiler combines the include path "../StdCUtil" with the relative path from the #include directive "StdCUtil/split.h".

To fix this, just use -I.. instead of -I../StdCUtil.

In my case, setting SQL Server Database Engine service startup account to NT AUTHORITY\NETWORK SERVICE failed, but setting it to NT Authority\System allowed me to succesfully install my SQL Server 2016 STD instance.

Just check the following snapshot.

Remember: you can avoid server rebooting using setup's SkipRules switch:

setup.exe /ACTION=INSTALL /SkipRules=RebootRequiredCheck

setup.exe /ACTION=UNINSTALL /SkipRules=RebootRequiredCheck

You are creating a Date object, which is a representation of a certain point in the timeline. This means that it will have all the parts necessary to represent it correctly, including minutes and seconds and so on. Because you initialize it from a string containing only a part of the date, the missing data will be defaulted.

I assume you are then "printing" this Date object, but without actually specifying a format like you did when parsing it. Use the same SimpleDateFormat but call the reverse method, format(Date) as Holger suggested

var groupedCustomerList = CustomerList.GroupBy(u => u.GroupID)
                                      .Select(grp =>new { GroupID =grp.Key, CustomerList = grp.ToList()})
                                      .ToList();

Yes, the value of any argument can be found using getArgs

@Before("execution(* com.mkyong.customer.bo.CustomerBo.addCustomer(..))")
public void logBefore(JoinPoint joinPoint) {

   Object[] signatureArgs = thisJoinPoint.getArgs();
   for (Object signatureArg: signatureArgs) {
      System.out.println("Arg: " + signatureArg);
      ...
   }
}

I'm going to answer my own question.

1. innerJoin should use the keyword "WITH" instead of "ON" (Doctrine's documentation [13.2.6. Helper methods] is inaccurate; [13.2.5. The Expr class] is correct)
2. no need to link foreign keys in join condition as they're already specified in the entity mapping.

Therefore, the following works for me

$qb->select('c')
    ->innerJoin('c.phones', 'p', 'WITH', 'p.phone = :phone')
    ->where('c.username = :username');

or

$qb->select('c')
    ->innerJoin('c.phones', 'p', Join::WITH, $qb->expr()->eq('p.phone', ':phone'))
    ->where('c.username = :username');

Just in case this is helpful to others, here's my anecdote:

I found this thread as a result of a problem I encountered while I was using Postman to send test data to my RESTEasy server, where- after a significant code change- I was getting nothing but 415 Unsupported Media Type errors.

Long story short, I tore everything out, eventually I tried to run the trivial file upload example I knew worked; it didn't. That's when I realized that the problem was with my Postman request. I normally don't send any special headers, but in a previous test I had added a "Content-Type": "application/json" header. OF COURSE, I was trying to upload "multipart/form-data." Removing it solved my issue.

Moral: Check your headers before you blow up your world. ;)

I'm not really sure if that was the situation with Roundcube version from May '12, but for current one the answer is that you can't delete roundcube_sessauth cookie from JavaScript, as it is marked as HttpOnly. And this means it's not accessible from JS client side code and can be removed only by server side script or by direct user action (via some browser mechanics like integrated debugger or some plugin).

I faced this issue, and resolved this issue using getchar() to catch the ('\n') new char

The m000493 method seems to perform some kind of XOR encryption. This means that the same method can be used for both encrypting and decrypting the text. All you have to do is reverse m0001cd:

string p0 = Encoding.UTF8.GetString(Convert.FromBase64String("OBFZDT..."));

string result = m000493(p0, "_p0lizei.");
//    result == "gaia^unplugged^Ta..."

with return m0001cd(builder3.ToString()); changed to return builder3.ToString();.

In your theme's functions.php:

function my_custom_js() {
    echo '<script type="text/javascript" src="myscript.js"></script>';
}
// Add hook for admin <head></head>
add_action( 'admin_head', 'my_custom_js' );
// Add hook for front-end <head></head>
add_action( 'wp_head', 'my_custom_js' );

Yet another alternative: 

Select FORMAT(date,'MM.yy')
...
...
group by FORMAT(date,'MM.yy')

It's an inlined image (png), encoded in base64. It can make a page faster: the browser doesn't have to query the server for the image data separately, saving a round trip.

(It can also make it slower if abused: these resources are not cached, so the bytes are included in each page load.)

why don't u try using an absolute xPath

//soap:Envelope[1]/soap:Body[1]/PaymentNotification[1]/payment

or since u know that it is a payment and payment doesn't have any attributes just select directly from payment

//soap:Envelope[1]/soap:Body[1]/PaymentNotification[1]/payment/*

var groupedCustomerList = userList
    .GroupBy(u => u.GroupID)
    .Select(grp => grp.ToList())
    .ToList();

Taking @chrissr's answer and running with it, this code can be implemented into a nice category on NSUserDefaults to save and retrieve custom objects:

@interface NSUserDefaults (NSUserDefaultsExtensions)

- (void)saveCustomObject:(id<NSCoding>)object
                     key:(NSString *)key;
- (id<NSCoding>)loadCustomObjectWithKey:(NSString *)key;

@end


@implementation NSUserDefaults (NSUserDefaultsExtensions)


- (void)saveCustomObject:(id<NSCoding>)object
                     key:(NSString *)key {
    NSData *encodedObject = [NSKeyedArchiver archivedDataWithRootObject:object];
    [self setObject:encodedObject forKey:key];
    [self synchronize];

}

- (id<NSCoding>)loadCustomObjectWithKey:(NSString *)key {
    NSData *encodedObject = [self objectForKey:key];
    id<NSCoding> object = [NSKeyedUnarchiver unarchiveObjectWithData:encodedObject];
    return object;
}

@end

Usage:

[[NSUserDefaults standardUserDefaults] saveCustomObject:myObject key:@"myKey"];

Even if that topic is quite old, I'd like to add something. If you overwrite equals for you classes, so it compares your getId, you can use:

customer = new Customer(id);
customers.get(customers.indexOf(customer));

Of course, you'd have to check for an IndexOutOfBounds-Exception, which oculd be translated into a null pointer or a custom CustomerNotFoundException.

Cast the integers to varchar first!

A tad late, but here goes.

How about http://wiki.apache.org/tomcat/UsingPhp if you just want to run the real php on tomcat.

Concerning running tomcat on port 80 there's always jsvc, just google jsvc + tomcat.

Have you tried rebuilding the statistics and/or the indexes on the Report_Opener table. All the recomplies of the SP won't be worth anything if the stats still show data from when the database was first inauguarated.

The initial query itself works quickly because the optimiser can see that the parameter will never be null. In the case of the SP the optimiser cannot be sure that the parameter will never be null.

Given it's SQL 2005, you can also try this It's similar to Oracle's MINUS command (opposite of UNION)

But I would also suggest adding the DATEPART ( hour, insertDate) column for debug

SELECT idCustomer FROM reservations 
EXCEPT
SELECT idCustomer FROM reservations WHERE DATEPART ( hour, insertDate) < 2

hyperlink1.attributes["href"] = "#"; or

Html:

<div class="outerDiv">
    <div class="innerDiv">Content</div>
</div>

    padding: 10px;
 }

 .innerDiv{
     border: 2px dashed #fff;
     min-height: 200px; //adding min-height as there is no content inside

UIColor's RGB components are scaled between 0 and 1, not up to 255.

Try

categoryTitle.textColor = [UIColor colorWithRed:(188/255.f) green:... blue:... alpha:1.0];

In Swift:

categoryTitle.textColor = UIColor(red: 188/255.0, green: ..., blue: ..., alpha: 1)

In 2015, there are at least six choices for JavaScript debugging in Eclipse:

• New since Eclipse 3.7: JavaScript Development Tools debugging support. The incubation part lists CrossFire support. That means, one can use Firefox + Firebug as page viewer without any Java code changes.
• New since October 2012: VJET JavaScript IDE
• Ajax Tools Framework
• Aptana provides JavaScript debugging capabilities.
• The commercial MyEclipse IDE also has JavaScript debugging support
• From the same stable as MyEclipse, the Webclipse plug-in has the same JavaScript debugging technology.

Adding to the above, here are a couple of videos which focus on "debugging JavaScript using eclipse"

• Debugging JavaScript using Eclipse and Chrome Tools
• Debugging JavaScript using Eclipse and CrossFire (with FB)

Outdated

• The Google Chrome Developer Tools for Java allow debugging using Chrome.

This code make clean dataframe:

df = pd.DataFrame({'a':[1,2], 'b':[3,4]})
#clean
df = pd.DataFrame()

inspired by this question I have written a blog along with the code snippet here. Below are some of the excerpts from the blog

SelectedItem – Selected Item helps to bind the actual value from the DataSource which will be displayed. This is of type object and we can bind any type derived from object type with this property. Since we will be using the MVVM binding for our combo boxes in that case this is the property which we can use to notify VM that item has been selected.

SelectedValue and SelectedValuePath – These are the two most confusing and misinterpreted properties for combobox. But these properties come to rescue when we want to bind our combobox with the value from already created object. Please check my last scenario in the following list to get a brief idea about the properties.

Try this. It uses the split function which is a core part of javascript, nothing to do with jQuery.

var parts = html.split(":-"),
    i, l
;
for (i = 0, l = parts.length; i < l; i += 2) {
    $("#" + parts[i]).text(parts[i + 1]);
}

You can use the API querySelector to select your element and then create a function with the element and the new classname as parameters. Using classlist for modern browsers, else for IE8. Then you can call the function after an event.

 //select the dom element
 var addClassVar = document.querySelector('.someclass');

 //define the addclass function
 var addClass = function(el,className){
   if (el.classList){
     el.classList.add(className);
   }
   else {
     el.className += ' ' + className;
  }
};

//call the function
addClass(addClassVar, 'newClass');

You shoud do something like :

print line.split()[0]

At the time of writing this answer, there was no method to embed which let the user navigate inside folders and view the files without her leaving the website (the method in other answers, makes everything open in a new tab on google drive website), so I made my own tool for it. To embed a drive, paste the iframe code below in your HTML:

<iframe src="https://googledriveembedder.collegefam.com/?key=YOUR_API_KEY&folderid=FOLDER_ID_WHIHCH_IS_PUBLICLY_VIEWABLE" style="border:none;" width="100%"></iframe>

In the above code, you need to have your own API key and the folder ID. You can set the height as per your wish.

To get the API key:

1.) Go to https://console.developers.google.com/ Create a new project.

2.) From the menu button, go to 'APIs and Services' --> 'Dashboard' --> Click on 'Enable APIs and Services'.

3.) Search for 'Google Drive API', enable it. Then go to "credentials' tab, and create credentials. Keep your API key unrestricted.

4.) Copy the newly generated API key.

To get the folder ID:

1.)Go to the google drive folder you want to embed (for example, drive.google.com/drive/u/0/folders/1v7cGug_e3lNT0YjhvtYrwKV7dGY-Nyh5u [this is not a real folder]) Ensure that the folder is publicly shared and visible to anyone.

2.) Copy the part after 'folders/', this is your folder ID.

Now put both the API key and folder id in the above code and embed.

Note: To hide the download button for files, add '&allowdl=no' at the end of the iframe's src URL.

I made the widget keeping mobile users in mind, however it suits both mobile and desktop. If you run into issues, leave a comment here. I have attached some screenshots of the content of the iframe here.

There is no specialized image component provided in Swing (which is sad in my opinion). So, there are a few options:

1. As @Reimeus said: Use a JLabel with an icon.

2. Create in the window builder a JPanel, that will represent the location of the image. Then add your own custom image component to the JPanel using a few lines of code you will never have to change. They should look like this:

   JImageComponent ic = new JImageComponent(myImageGoesHere);
   imagePanel.add(ic);
   

   where JImageComponent is a self created class that extends JComponent that overrides the paintComponent() method to draw the image.

"C:\Program Files\PuTTY\pscp.exe" -scp file.py server.com:

file.py will be uploaded into your HOME dir on remote server.

or when the remote server has a different user, use "C:\Program Files\PuTTY\pscp.exe" -l username -scp file.py server.com:

After connecting to the server pscp will ask for a password.

If the colspan or rowspan is all set to 1, counting the children tds will give the correct answer. However, if there are spans, we cannot count the number of columns exactly, even by the maximum number of tds of the rows. Consider the following example:

var mytable = document.getElementById('table')_x000D_
for (var i=0; i < mytable.rows.length; ++i) {_x000D_
 document.write(mytable.rows[i].cells.length + "<br>");_x000D_
}

table, th, td {_x000D_
  border: 1px solid black;_x000D_
  border-collapse: collapse;_x000D_
  padding: 3px;_x000D_
}

<table id="table">_x000D_
    <thead>_x000D_
        <tr>_x000D_
            <th colspan="2">Header</th>_x000D_
            <th rowspan="2">Hi</th>_x000D_
        </tr>_x000D_
        <tr>_x000D_
            <th>Month</th>_x000D_
            <th>Savings</th>_x000D_
        </tr>_x000D_

        <tr>_x000D_

You need to add the attribute "formnovalidate" to the control that is triggering the browser validation, e.g.:

<input type="image" id="fblogin" formnovalidate src="/images/facebook_connect.png">

Try like this..

NameVirtualHost *:80
<VirtualHost *:80>
    ServerAdmin [email protected]
    ServerName www.cmsplus.dev
    ServerAlias cmsplus.dev

    DocumentRoot /var/www/cmsplus.dev/public

    LogLevel warn
    ErrorLog /var/www/cmsplus.dev/log/error.log
    CustomLog /var/www/cmsplus.dev/log/access.log combined
</VirtualHost>

and add entry in /etc/hosts

127.0.0.1 www.cmsplus.dev

restart apache..

You can easy change collation in Microsoft SQL Server Management studio.

• right click table -> design.
• choose your column, scroll down i column properties to Collation.
• Set your sort preference by check "Case Sensitive"

There is also the rather spiffy FileStream, introduced in SQL Server 2008.

Similar to zproxy's answer above I have used the folowing code in the Gloabal.asax.cs to achieve this:

public class Global : System.Web.HttpApplication
{
    protected void Application_BeginRequest(object sender, EventArgs e)
    {
        if (Request.Url.AbsolutePath.EndsWith("/"))
        {
            Server.Transfer(Request.Url.AbsolutePath + "index.aspx");
        }
    }
}

1) I like a statusline (with the filename, ascii value (decimal), hex value, and the standard lines, cols, and %):

set statusline=%t%h%m%r%=[%b\ 0x%02B]\ \ \ %l,%c%V\ %P
" Always show a status line
set laststatus=2
"make the command line 1 line high
set cmdheight=1

2) I also like mappings for split windows.

" <space> switches to the next window (give it a second)
" <space>n switches to the next window
" <space><space> switches to the next window and maximizes it
" <space>= Equalizes the size of all windows
" + Increases the size of the current window
" - Decreases the size of the current window

 :map <space> <c-W>w
:map <space>n <c-W>w
:map <space><space> <c-W>w<c-W>_
:map <space>= <c-W>=
if bufwinnr(1)
  map + <c-W>+
  map - <c-W>-

You can change drawableSize of your DrawerArrow like this:

<style name="MyTheme" parent="android:Theme.WithActionBar">
    <item name="drawerArrowStyle">@style/DrawerArrowStyle</item>
</style>

<style name="DrawerArrowStyle" parent="Widget.AppCompat.DrawerArrowToggle">
    <item name="barLength">24dp</item>
    <item name="arrowShaftLength">24dp</item>
    <item name="arrowHeadLength">10dp</item>
    <item name="drawableSize">42dp</item> //this is your answer
</style>

It isn't correct answer, because you can't choose padding side and DrawerArrow icon scaling when change drawableSize (drawableSize = width = height). But you can margin from left. To margin from right do

findViewById(android.R.id.home).setPadding(10, 0, 5, 0);

Handle SIGPIPE Locally

It's usually best to handle the error locally rather than in a global signal event handler since locally you will have more context as to what's going on and what recourse to take.

I have a communication layer in one of my apps that allows my app to communicate with an external accessory. When a write error occurs I throw and exception in the communication layer and let it bubble up to a try catch block to handle it there.

Code:

The code to ignore a SIGPIPE signal so that you can handle it locally is:

// We expect write failures to occur but we want to handle them where 
// the error occurs rather than in a SIGPIPE handler.
signal(SIGPIPE, SIG_IGN);

This code will prevent the SIGPIPE signal from being raised, but you will get a read / write error when trying to use the socket, so you will need to check for that.

The compiler only knows that the code is or isn't reachable if you use "return". Think of Environment.Exit() as a function that you call, and the compiler don't know that it will close the application.

You just need to filter the cars that have a null name:

requiredCars = cars.stream()
                   .filter(c -> c.getName() != null)
                   .filter(c -> c.getName().startsWith("M"));

You can also modify your theme using theme Editor by clicking :

Tools -> Android -> Theme Editor

Then, you don't even need to put some extra content in your .xml or .class files.

This is not possible with native HTML input elements. You can use webshim polyfill, which gives you this option by using this markup.

<input type="date" data-date-inline-picker="true" />

Here is a small demo

For other languages like German, Spanish, Danish, French etc that contain special characters (like German "Umlaute" as ü, ä, ö) simply add these to the regex search string:

Example for German:

re.sub('[^A-ZÜÖÄa-z0-9]+', '', mystring)

IF EXISTS (SELECT 1 FROM Table WHERE FieldValue='') 
BEGIN
   SELECT TableID FROM Table WHERE FieldValue=''
END
ELSE
BEGIN
   INSERT INTO TABLE(FieldValue) VALUES('')
   SELECT SCOPE_IDENTITY() AS TableID
END

See here for more information on IF ELSE

Note: written without a SQL Server install handy to double check this but I think it is correct

Also, I've changed the EXISTS bit to do SELECT 1 rather than SELECT * as you don't care what is returned within an EXISTS, as long as something is I've also changed the SCOPE_IDENTITY() bit to return just the identity assuming that TableID is the identity column

Numpy's r_ convenience function can also create evenly spaced lists with syntax np.r_[start:stop:steps]. If steps is a real number (ending on j), then the end point is included, equivalent to np.linspace(start, stop, step, endpoint=1), otherwise not.

>>> np.r_[-1:1:6j, [0]*3, 5, 6]
array([-1. , -0.6, -0.2,  0.2,  0.6,  1.])

You can also directly concatente other arrays and also scalars:

>>> np.r_[-1:1:6j, [0]*3, 5, 6]
array([-1. , -0.6, -0.2,  0.2,  0.6,  1. ,  0. ,  0. ,  0. ,  5. ,  6. ])

In simple terms we can written as follows,

for(var i=1;i<=31;i++)
    i=(i<10) ? '0'+i : i;

//Because most of the time we need this for day, month or amount matters.

I believe, the 500ms run in the background, while the rest of the code continues to execute and empties the list.

Then after 500ms nothing happens, as no function-call is implemented in the after-callup (same as frame.after(500, function=None))

Although scp supports recursive directory copying with the -r option, it does not support filtering of the files. There are several ways to accomplish your task, but I would probably rely on find, xargs, tar, and ssh instead of scp.

find . -type d -wholename '*bench*/image' \
| xargs tar cf - \
| ssh user@remote tar xf - -C /my/dir

The rsync solution can be made to work, but you are missing some arguments. rsync also needs the r switch to recurse into subdirectories. Also, if you want the same security of scp, you need to do the transfer under ssh. Something like:

rsync -avr -e "ssh -l user" --exclude 'fl_*' ./bench* remote:/my/dir

html, body {
    height:100%;
}
#wrapper {
    min-height:100%;
}

You can using the socket module to simply check if a port is open or not.

It would look something like this.

import socket
sock = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
result = sock.connect_ex(('127.0.0.1',80))
if result == 0:
   print "Port is open"
else:
   print "Port is not open"
sock.close()

Alternate solution by using JobScheduler, it can start service in background in regular interval of time.

Firstly make class named as Util.java

import android.app.job.JobInfo;
import android.app.job.JobScheduler;
import android.content.ComponentName;
import android.content.Context;

public class Util {
// schedule the start of the service every 10 - 30 seconds
public static void schedulerJob(Context context) {
    ComponentName serviceComponent = new ComponentName(context,TestJobService.class);
    JobInfo.Builder builder = new JobInfo.Builder(0,serviceComponent);
    builder.setMinimumLatency(1*1000);    // wait at least
    builder.setOverrideDeadline(3*1000);  //delay time
    builder.setRequiredNetworkType(JobInfo.NETWORK_TYPE_UNMETERED);  // require unmetered network
    builder.setRequiresCharging(false);  // we don't care if the device is charging or not
    builder.setRequiresDeviceIdle(true); // device should be idle
    System.out.println("(scheduler Job");

    JobScheduler jobScheduler = null;
    if (android.os.Build.VERSION.SDK_INT >= android.os.Build.VERSION_CODES.M) {
        jobScheduler = context.getSystemService(JobScheduler.class);
    }
    jobScheduler.schedule(builder.build());
   }
  }

Then, make JobService class named as TestJobService.java

import android.app.job.JobParameters;
import android.app.job.JobService;
import android.widget.Toast;
 
  /**
   * JobService to be scheduled by the JobScheduler.
   * start another service
   */ 
public class TestJobService extends JobService {
@Override
public boolean onStartJob(JobParameters params) {
    Util.schedulerJob(getApplicationContext()); // reschedule the job
    Toast.makeText(this, "Bg Service", Toast.LENGTH_SHORT).show();
    return true;
}

@Override
public boolean onStopJob(JobParameters params) {
    return true;
  }
 }

After that BroadCast Receiver class named ServiceReceiver.java

import android.content.BroadcastReceiver;
import android.content.Context;
import android.content.Intent;

 public class ServiceReceiver extends BroadcastReceiver {
 @Override
public void onReceive(Context context, Intent intent) {
    Util.schedulerJob(context);
 }
}

Update Manifest file with service and receiver class code

<receiver android:name=".ServiceReceiver" >
        <intent-filter>
            <action android:name="android.intent.action.BOOT_COMPLETED" />
        </intent-filter>
    </receiver>
    <service
        android:name=".TestJobService"
        android:label="Word service"
        android:permission="android.permission.BIND_JOB_SERVICE" >

    </service>

Left main_intent launcher to mainActivity.java file which is created by default, and changes in MainActivity.java file are

import android.support.v7.app.AppCompatActivity;
import android.os.Bundle;

public class MainActivity extends AppCompatActivity {

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);
    Util.schedulerJob(getApplicationContext());
  }
 }

WOOAAH!! Background Service starts without Foreground service

[Edit]: You can use Work Manager for any type of background tasks in Android.

An interface can extend other interfaces. Also an interface cannot implement any other interface. When it comes to a class, it can extend one other class and implement any number of interfaces.

class A extends B implements C,D{...}

This will find the first parent with class box then find the first child class with regex matching something and get the id.

$(".mylink").closest(".box").find('[class*="something"]').first().attr("id")

You need to use the new configuration option (this works for ng build and ng serve as well)

ng serve --configuration=local

or

ng serve -c local

If you look at your angular.json file, you'll see that you have finer control over settings for each configuration (aot, optimizer, environment files,...)

"configurations": {
  "production": {
    "optimization": true,
    "outputHashing": "all",
    "sourceMap": false,
    "extractCss": true,
    "namedChunks": false,
    "aot": true,
    "extractLicenses": true,
    "vendorChunk": false,
    "buildOptimizer": true,
    "fileReplacements": [
      {
        "replace": "src/environments/environment.ts",
        "with": "src/environments/environment.prod.ts"
      }
    ]
  }
}

You can get more info here for managing environment specific configurations.

As pointed in the other response below, if you need to add a new 'environment', you need to add a new configuration to the build task and, depending on your needs, to the serve and test tasks as well.

Adding a new environment

Edit: To make it clear, file replacements must be specified in the build section. So if you want to use ng serve with a specific environment file (say dev2), you first need to modify the build section to add a new dev2 configuration

"build": {
   "configurations": {
        "dev2": {

          "fileReplacements": [
            {
              "replace": "src/environments/environment.ts",
              "with": "src/environments/environment.dev2.ts"
            }
            /* You can add all other options here, such as aot, optimization, ... */
          ],
          "serviceWorker": true
        },

Then modify your serve section to add a new configuration as well, pointing to the dev2 build configuration you just declared

"serve":
      "configurations": {
        "dev2": {
          "browserTarget": "projectName:build:dev2"
        }

Then you can use ng serve -c dev2, which will use the dev2 config file

You could use std::hex

Eg.

std::cout << std::hex << packet;

In case you want to return a string in 00:00 format...

convertMinsToHrsMins: function (minutes) {
  var h = Math.floor(minutes / 60);
  var m = minutes % 60;
  h = h < 10 ? '0' + h : h;
  m = m < 10 ? '0' + m : m;
  return h + ':' + m;
}

Thanks for the up-votes. Here's a slightly tidier ES6 version :)

const convertMinsToHrsMins = (mins) => {
  let h = Math.floor(mins / 60);
  let m = mins % 60;
  h = h < 10 ? '0' + h : h;
  m = m < 10 ? '0' + m : m;
  return `${h}:${m}`;
}

The benefits of super() in single-inheritance are minimal -- mostly, you don't have to hard-code the name of the base class into every method that uses its parent methods.

However, it's almost impossible to use multiple-inheritance without super(). This includes common idioms like mixins, interfaces, abstract classes, etc. This extends to code that later extends yours. If somebody later wanted to write a class that extended Child and a mixin, their code would not work properly.

See http://underscorejs.org/#isEmpty

isEmpty_.isEmpty(object) Returns true if an enumerable object contains no values (no enumerable own-properties). For strings and array-like objects _.isEmpty checks if the length property is 0.

Gmail: OAuth

• Goto the link
• Login with your gmail username password
• Click on the google menu at the top left
• Click API Manager
• Click on Credentials
• Click Create Credentials and select OAuth Client
• Select Web Application as Application type and Enter the Name-> Enter Authorised Redirect URL (Eg: http://localhost:53922/signin-google) ->Click on Create button. This will create the credentials. Pls make a note of Client ID and Secret ID. Finally click OK to close the credentials pop up.
• Next important step is to enable the Google API. Click on Overview in the left pane.
• Click on the Google API under Social APIs section.
• Click Enable.

That’s all from the Google part.

Come back to your application, open App_start/Startup.Auth.cs and uncomment the following snippet

        app.UseGoogleAuthentication(new GoogleOAuth2AuthenticationOptions()
        {
            ClientId = "",
            ClientSecret = ""
        });

Update the ClientId and ClientSecret with the values from Google API credentials which you have created already.

• Run your application
• Click Login
• You will see the Google button under ‘Use Another Section to log in’ section
• Click on the Google button
• Application will prompt you to enter the username and password
• Enter the gmail username and password and click Sign In
• This will perform the OAuth and come back to your application and prompting you to register with the Gmail id.
• Click register to register the Gmail id into your application database.
• You will see the Identity details appear in the top as normal registration
• Try logout and login again thru Gmail. This will automatically logs you into the app.

Write a vba proc like:

Sub E_1()
    Call sndPlaySound32(ThisWorkbook.Path & "\e1.wav", 0)
    Range("AG" & (ActiveCell.Row)).Select 'go to column AG in the same row
End Sub

then go to developer tab, macros, select the macro, click options, then add a shortcut letter or button.

webpack 4 now offers a version property that can be used!

Probably the shortest version:

[System.Collections.ArrayList]$someArray

It is also faster because it does not call relatively expensive New-Object.

Use Passay library which is powerful api.

Simple try to remove name attribute from input element.
So it has to look like

<input type="checkbox" checked="" id="class_box_2" value="2">

What do you mean by "initialize an array to zero"? Arrays don't contain "zero" -- they can contain "zero elements", which is the same as "an empty list". Or, you could have an array with one element, where that element is a zero: my @array = (0);

my @array = (); should work just fine -- it allocates a new array called @array, and then assigns it the empty list, (). Note that this is identical to simply saying my @array;, since the initial value of a new array is the empty list anyway.

Are you sure you are getting an error from this line, and not somewhere else in your code? Ensure you have use strict; use warnings; in your module or script, and check the line number of the error you get. (Posting some contextual code here might help, too.)

I would either:

1. Try to ssh from the command line and accept the public key (the host will be added to ~/.ssh/known_hosts and everything should then work fine from Jsch) -OR-

2. Configure JSch to not use "StrictHostKeyChecking" (this introduces insecurities and should only be used for testing purposes), using the following code:

   java.util.Properties config = new java.util.Properties(); 
   config.put("StrictHostKeyChecking", "no");
   session.setConfig(config);
   

Option #1 (adding the host to the ~/.ssh/known_hosts file) has my preference.

You can also use : mysql> select user,host from mysql.user;

GridLayout is often not the best choice for buttons, although it might be for your application. A good reference is the tutorial on using Layout Managers. If you look at the GridLayout example, you'll see the buttons look a little silly -- way too big.

A better idea might be to use a FlowLayout for your buttons, or if you know exactly what you want, perhaps a GroupLayout. (Sun/Oracle recommend that GroupLayout or GridBag layout are better than GridLayout when hand-coding.)

You can also open a required file through a prompt, This helps when you want to select file from different path and different file.

Sub openwb()
Dim wkbk As Workbook
Dim NewFile As Variant

NewFile = Application.GetOpenFilename("microsoft excel files (*.xlsm*), *.xlsm*")

If NewFile <> False Then
Set wkbk = Workbooks.Open(NewFile)
End If
End Sub

Read this for detail :

// 1 define a function pointer and initialize to NULL

int (TMyClass::*pt2ConstMember)(float, char, char) const = NULL;

// C++

class TMyClass
{
public:
   int DoIt(float a, char b, char c){ cout << "TMyClass::DoIt"<< endl; return a+b+c;};
   int DoMore(float a, char b, char c) const
         { cout << "TMyClass::DoMore" << endl; return a-b+c; };

   /* more of TMyClass */
};
pt2ConstMember = &TMyClass::DoIt; // note: <pt2Member> may also legally point to &DoMore

// Calling Function using Function Pointer

(*this.*pt2ConstMember)(12, 'a', 'b');

Since you can also input numbers as well as fixed type strings, the answer should actually be:

function isBlank(value) {
  return $.trim(value);
}

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.

Generally, FileMode.Create is what you're looking for.

You should prefer the JPA methods most of the time, and the update for batch processing tasks.

A JPA or Hibernate entity can be in one of the following four states:

• Transient (New)
• Managed (Persistent)
• Detached
• Removed (Deleted)

The transition from one state to the other is done via the EntityManager or Session methods.

For instance, the JPA EntityManager provides the following entity state transition methods.

The Hibernate Session implements all the JPA EntityManager methods and provides some additional entity state transition methods like save, saveOrUpdate and update.

Persist

To change the state of an entity from Transient (New) to Managed (Persisted), we can use the persist method offered by the JPA EntityManager which is also inherited by the Hibernate Session.

The persist method triggers a PersistEvent which is handled by the DefaultPersistEventListener Hibernate event listener.

Therefore, when executing the following test case:

doInJPA(entityManager -> {
    Book book = new Book()
    .setIsbn("978-9730228236")
    .setTitle("High-Performance Java Persistence")
    .setAuthor("Vlad Mihalcea");

    entityManager.persist(book);
    
    LOGGER.info(
        "Persisting the Book entity with the id: {}", 
        book.getId()
    );
});

Hibernate generates the following SQL statements:

CALL NEXT VALUE FOR hibernate_sequence

-- Persisting the Book entity with the id: 1

INSERT INTO book (
    author, 
    isbn, 
    title, 
    id
) 
VALUES (
    'Vlad Mihalcea', 
    '978-9730228236', 
    'High-Performance Java Persistence', 
    1
)

Notice that the id is assigned prior to attaching the Book entity to the current Persistence Context. This is needed because the managed entities are stored in a Map structure where the key is formed by the entity type and its identifier and the value is the entity reference. This is the reason why the JPA EntityManager and the Hibernate Session are known as the First-Level Cache.

When calling persist, the entity is only attached to the currently running Persistence Context, and the INSERT can be postponed until the flush is called.

The only exception is the IDENTITY which triggers the INSERT right away since that's the only way it can get the entity identifier. For this reason, Hibernate cannot batch inserts for entities using the IDENTITY generator.

Save

The Hibernate-specific save method predates JPA and it's been available since the beginning of the Hibernate project.

The save method triggers a SaveOrUpdateEvent which is handled by the DefaultSaveOrUpdateEventListener Hibernate event listener. Therefore, the save method is equivalent to the update and saveOrUpdate methods.

To see how the save method works, consider the following test case:

doInJPA(entityManager -> {
    Book book = new Book()
    .setIsbn("978-9730228236")
    .setTitle("High-Performance Java Persistence")
    .setAuthor("Vlad Mihalcea");

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

    Long id = (Long) session.save(book);

    LOGGER.info(
        "Saving the Book entity with the id: {}", 
        id
    );
});

When running the test case above, Hibernate generates the following SQL statements:

CALL NEXT VALUE FOR hibernate_sequence

-- Saving the Book entity with the id: 1

INSERT INTO book (
    author, 
    isbn, 
    title, 
    id
) 
VALUES (
    'Vlad Mihalcea', 
    '978-9730228236', 
    'High-Performance Java Persistence', 
    1
)

As you can see, the outcome is identical to the persist method call. However, unlike persist, the save method returns the entity identifier.

Update

The Hibernate-specific update method is meant to bypass the dirty checking mechanism and force an entity update at the flush time.

The update method triggers a SaveOrUpdateEvent which is handled by the DefaultSaveOrUpdateEventListener Hibernate event listener. Therefore, the update method is equivalent to the save and saveOrUpdate methods.

To see how the update method works consider the following example which persists a Book entity in one transaction, then it modifies it while the entity is in the detached state, and it forces the SQL UPDATE using the update method call.

Book _book = doInJPA(entityManager -> {
    Book book = new Book()
    .setIsbn("978-9730228236")
    .setTitle("High-Performance Java Persistence")
    .setAuthor("Vlad Mihalcea");

    entityManager.persist(book);

    return book;
});

LOGGER.info("Modifying the Book entity");

_book.setTitle(
    "High-Performance Java Persistence, 2nd edition"
);

doInJPA(entityManager -> {
    Session session = entityManager.unwrap(Session.class);

    session.update(_book);

    LOGGER.info("Updating the Book entity");
});

When executing the test case above, Hibernate generates the following SQL statements:

CALL NEXT VALUE FOR hibernate_sequence

INSERT INTO book (
    author, 
    isbn, 
    title, 
    id
) 
VALUES (
    'Vlad Mihalcea', 
    '978-9730228236', 
    'High-Performance Java Persistence', 
    1
)

-- Modifying the Book entity
-- Updating the Book entity

UPDATE 
    book 
SET 
    author = 'Vlad Mihalcea', 
    isbn = '978-9730228236', 
    title = 'High-Performance Java Persistence, 2nd edition'
WHERE 
    id = 1

Notice that the UPDATE is executed during the Persistence Context flush, right before commit, and that's why the Updating the Book entity message is logged first.

Using @SelectBeforeUpdate to avoid unnecessary updates

Now, the UPDATE is always going to be executed even if the entity was not changed while in the detached state. To prevent this, you can use the @SelectBeforeUpdate Hibernate annotation which will trigger a SELECT statement that fetched loaded state which is then used by the dirty checking mechanism.

So, if we annotate the Book entity with the @SelectBeforeUpdate annotation:

@Entity(name = "Book")
@Table(name = "book")
@SelectBeforeUpdate
public class Book {

    //Code omitted for brevity
}

And execute the following test case:

Book _book = doInJPA(entityManager -> {
    Book book = new Book()
    .setIsbn("978-9730228236")
    .setTitle("High-Performance Java Persistence")
    .setAuthor("Vlad Mihalcea");

    entityManager.persist(book);

    return book;
});

doInJPA(entityManager -> {
    Session session = entityManager.unwrap(Session.class);

    session.update(_book);
});

Hibernate executes the following SQL statements:

INSERT INTO book (
    author, 
    isbn, 
    title, 
    id
) 
VALUES (
    'Vlad Mihalcea', 
    '978-9730228236', 
    'High-Performance Java Persistence', 
    1
)

SELECT 
    b.id,
    b.author AS author2_0_,
    b.isbn AS isbn3_0_,
    b.title AS title4_0_
FROM 
    book b
WHERE 
    b.id = 1

Notice that, this time, there is no UPDATE executed since the Hibernate dirty checking mechanism has detected that the entity was not modified.

SaveOrUpdate

The Hibernate-specific saveOrUpdate method is just an alias for save and update.

The saveOrUpdate method triggers a SaveOrUpdateEvent which is handled by the DefaultSaveOrUpdateEventListener Hibernate event listener. Therefore, the update method is equivalent to the save and saveOrUpdate methods.

Now, you can use saveOrUpdate when you want to persist an entity or to force an UPDATE as illustrated by the following example.

Book _book = doInJPA(entityManager -> {
    Book book = new Book()
    .setIsbn("978-9730228236")
    .setTitle("High-Performance Java Persistence")
    .setAuthor("Vlad Mihalcea");

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

    return book;
});

_book.setTitle("High-Performance Java Persistence, 2nd edition");

doInJPA(entityManager -> {
    Session session = entityManager.unwrap(Session.class);
    session.saveOrUpdate(_book);
});

Beware of the NonUniqueObjectException

One problem that can occur with save, update, and saveOrUpdate is if the Persistence Context already contains an entity reference with the same id and of the same type as in the following example:

Book _book = doInJPA(entityManager -> {
    Book book = new Book()
    .setIsbn("978-9730228236")
    .setTitle("High-Performance Java Persistence")
    .setAuthor("Vlad Mihalcea");

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

    return book;
});

_book.setTitle(
    "High-Performance Java Persistence, 2nd edition"
);

try {
    doInJPA(entityManager -> {
        Book book = entityManager.find(
            Book.class, 
            _book.getId()
        );

        Session session = entityManager.unwrap(Session.class);
        session.saveOrUpdate(_book);
    });
} catch (NonUniqueObjectException e) {
    LOGGER.error(
        "The Persistence Context cannot hold " +
        "two representations of the same entity", 
        e
    );
}

Now, when executing the test case above, Hibernate is going to throw a NonUniqueObjectException because the second EntityManager already contains a Book entity with the same identifier as the one we pass to update, and the Persistence Context cannot hold two representations of the same entity.

org.hibernate.NonUniqueObjectException: 
    A different object with the same identifier value was already associated with the session : [com.vladmihalcea.book.hpjp.hibernate.pc.Book#1]

Merge

To avoid the NonUniqueObjectException, you need to use the merge method offered by the JPA EntityManager and inherited by the Hibernate Session as well.

The merge fetches a new entity snapshot from the database if there is no entity reference found in the Persistence Context, and it copies the state of the detached entity passed to the merge method.

The merge method triggers a MergeEvent which is handled by the DefaultMergeEventListener Hibernate event listener.

To see how the merge method works consider the following example which persists a Book entity in one transaction, then it modifies it while the entity is in the detached state, and passes the detached entity to merge in a subsequence Persistence Context.

Book _book = doInJPA(entityManager -> {
    Book book = new Book()
    .setIsbn("978-9730228236")
    .setTitle("High-Performance Java Persistence")
    .setAuthor("Vlad Mihalcea");

    entityManager.persist(book);

    return book;
});

LOGGER.info("Modifying the Book entity");

_book.setTitle(
    "High-Performance Java Persistence, 2nd edition"
);

doInJPA(entityManager -> {
    Book book = entityManager.merge(_book);

    LOGGER.info("Merging the Book entity");

    assertFalse(book == _book);
});

When running the test case above, Hibernate executed the following SQL statements:

INSERT INTO book (
    author, 
    isbn, 
    title, 
    id
) 
VALUES (
    'Vlad Mihalcea', 
    '978-9730228236', 
    'High-Performance Java Persistence', 
    1
)

-- Modifying the Book entity

SELECT 
    b.id,
    b.author AS author2_0_,
    b.isbn AS isbn3_0_,
    b.title AS title4_0_
FROM 
    book b
WHERE 
    b.id = 1

-- Merging the Book entity

UPDATE 
    book 
SET 
    author = 'Vlad Mihalcea', 
    isbn = '978-9730228236', 
    title = 'High-Performance Java Persistence, 2nd edition'
WHERE 
    id = 1

Notice that the entity reference returned by merge is different than the detached one we passed to the merge method.

Now, although you should prefer using JPA merge when copying the detached entity state, the extra SELECT can be problematic when executing a batch processing task.

For this reason, you should prefer using update when you are sure that there is no entity reference already attached to the currently running Persistence Context and that the detached entity has been modified.

Conclusion

To persist an entity, you should use the JPA persist method. To copy the detached entity state, merge should be preferred. The update method is useful for batch processing tasks only. The save and saveOrUpdate are just aliases to update and you should not probably use them at all.

Some developers call save even when the entity is already managed, but this is a mistake and triggers a redundant event since, for managed entities, the UPDATE is automatically handled at the Persistence context flush time.

Command CHCP shows the current codepage. It has three digits: 8xx and is different from Windows 12xx. So typing a English-only text you wouldn't see any difference, but an extended codepage (like Cyrillic) will be printed wrongly.

This solution above seems to be the best to me, but it didn't work for me, so I did it as follows:

AssemblyName assemblyName = AssemblyName.GetAssemblyName(HttpContext.Current.Server.MapPath("~\\Bin\\AnotherAssembly.dll"));
string typeAssemblyQualifiedName = string.Join(", ", "MyNamespace.MyType", assemblyName.FullName);

Type myType = Type.GetType(typeAssemblyQualifiedName);

The precondition is that you know the path of the assembly. In my case I know it because this is an assembly built from another internal project and its included in our project's bin folder.

In case it matters I am using Visual Studio 2013, my target .NET is 4.0. This is an ASP.NET project, so I am getting absolute path via HttpContext. However, absolute path is not a requirement as it seems from MSDN on AssemblyQualifiedNames

You can run Xcode on Linux NATIVELY using Darling:

Darling is a translation layer that lets you run macOS software on Linux

Once installed you can install Xcode via command-line developer tool following this link.

As mentioned in other answers ORDER BY 1 orders by the first column.

I came across another example of where you might use it though. We have certain queries which need to be ordered select the same column. You would get a SQL error if ordering by Name in the below.

SELECT Name, Name FROM Segment ORDER BY 1

If the entire program should stop use sys.exit() otherwise just use an empty return.

We can as well start an application by knowing application type and feeding it with data:

adb shell am start -d "file:///sdcard/sample.3gp" -t "video/3gp" -a android.intent.action.VIEW

This command displays available Video Players to play sample.3gp file

Easiest way would probably be with jQuery, as follows:

$(document).ready(function(){
  $("#_1234").attr("checked","checked");
})

This adds a new attribute "checked" (which in HTML does not need a value). Just remember to include the jQuery library:

<script src="http://ajax.googleapis.com/ajax/libs/jquery/1.10.2/jquery.min.js"></script>

You could try using £ or £ instead of embedding the character directly; if you embed it directly, you're more likely to run into encoding issues in which your editor saves the file is ISO-8859-1 but it's interpreted as UTF-8, or vice versa.

If you want to embed it (or other Unicode characters) directly, make sure you actually save your file as UTF-8, and set the encoding as you did with the Content-Type header. Make sure when you get the file from the server that the header is present and correct, and that the file hasn't been transcoded by the web server.

Try this:

<link href="img/favicon.ico" rel="shortcut icon" type="image/x-icon" />

Try getting the input stream from this you can then get the text data as so:-

    URL url;
    HttpURLConnection urlConnection = null;
    try {
        url = new URL("http://www.mysite.se/index.asp?data=99");

        urlConnection = (HttpURLConnection) url
                .openConnection();

        InputStream in = urlConnection.getInputStream();

        InputStreamReader isw = new InputStreamReader(in);

        int data = isw.read();
        while (data != -1) {
            char current = (char) data;
            data = isw.read();
            System.out.print(current);
        }
    } catch (Exception e) {
        e.printStackTrace();
    } finally {
        if (urlConnection != null) {
            urlConnection.disconnect();
        }    
    }

You can probably use other inputstream readers such as buffered reader also.

The problem is that when you open the connection - it does not 'pull' any data.

Another scenario that can cause this exception is with DataBinding, that is when you use something like this in your layout

<?xml version="1.0" encoding="utf-8"?>
<layout xmlns:android="http://schemas.android.com/apk/res/android">

    <data>

        <variable
            name="model"
            type="point.to.your.model"/>
    </data>
    <TextView
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:text="@{model.someIntegerVariable}"/>

</layout>

Notice that the variable I'm using is an Integer and I'm assigning it to the text field of the TextView. Since the TextView already has a method with signature of setText(int) it will use this method instead of using the setText(String) and cast the value. Thus the TextView thinks of your input number as a resource value which obviously is not valid.

Solution is to cast your int value to string like this

android:text="@{String.valueOf(model.someIntegerVariable)}"

[Update]

The original answer was written prior to jQuery 1.3, and the functions that existed at the time where not adequate by themselves to calculate the whole width.

Now, as J-P correctly states, jQuery has the functions outerWidth and outerHeight which include the border and padding by default, and also the margin if the first argument of the function is true

[Original answer]

The width method no longer requires the dimensions plugin, because it has been added to the jQuery Core

What you need to do is get the padding, margin and border width-values of that particular div and add them to the result of the width method

Something like this:

var theDiv = $("#theDiv");
var totalWidth = theDiv.width();
totalWidth += parseInt(theDiv.css("padding-left"), 10) + parseInt(theDiv.css("padding-right"), 10); //Total Padding Width
totalWidth += parseInt(theDiv.css("margin-left"), 10) + parseInt(theDiv.css("margin-right"), 10); //Total Margin Width
totalWidth += parseInt(theDiv.css("borderLeftWidth"), 10) + parseInt(theDiv.css("borderRightWidth"), 10); //Total Border Width

Split into multiple lines to make it more readable

That way you will always get the correct computed value, even if you change the padding or margin values from the css

Here's my late entry. I didn't like any of the others for various reasons, so I wrote my own.

This version features:

• Use of StringBuilder only. No ToArray() calls or other extension methods. It doesn't look as pretty as some of the other responses, but I consider this a core function so efficiency is more important than having "fluent", "one-liner" code which hide inefficiencies.

• Handles multiple values per key. (Didn't need it myself but just to silence Mauricio ;)

  public string ToQueryString(NameValueCollection nvc)
  {
      StringBuilder sb = new StringBuilder("?");
  
      bool first = true;
  
      foreach (string key in nvc.AllKeys)
      {
          foreach (string value in nvc.GetValues(key))
          {
              if (!first)
              {
                  sb.Append("&");
              }
  
              sb.AppendFormat("{0}={1}", Uri.EscapeDataString(key), Uri.EscapeDataString(value));
  
              first = false;
          }
      }
  
      return sb.ToString();
  }
  

Example Usage

        var queryParams = new NameValueCollection()
        {
            { "x", "1" },
            { "y", "2" },
            { "foo", "bar" },
            { "foo", "baz" },
            { "special chars", "? = &" },
        };

        string url = "http://example.com/stuff" + ToQueryString(queryParams);

        Console.WriteLine(url);

Output

http://example.com/stuff?x=1&y=2&foo=bar&foo=baz&special%20chars=%3F%20%3D%20%26

window object is made available through $window service for easier testing and mocking, you can go with something like:

$scope.reloadPage = function(){$window.location.reload();}

And :

<a ng-click="reloadPage"  class="navbar-brand" title="home"  data-translate>PORTAL_NAME</a>

As a side note, i don't think $route.reload() actually reloads the page, but only the route.

Michael Dowling's very actively maintained Guzzle is a good way to go. Apart from the elegant interface, asynchronous calling and PSR compliance, it makes the authentication headers for REST calls dead simple:

// Create a client with a base URL
$client = new GuzzleHttp\Client(['base_url' => 'http://myservices.io']);

// Send a request to http://myservices.io/status with basic authentication
$response = $client->get('/status', ['auth' => ['username', 'password']]);

See the docs.

Actually, there's an easier (built in) way of doing this:

Color.decode("#FFCCEE");

I recommend you try to suppress specific warnings by using @SuppressWarnings("squid:S2078").

For suppressing multiple warnings you can do it like this @SuppressWarnings({"squid:S2078", "squid:S2076"})

There is also the //NOSONAR comment that tells SonarQube to ignore all errors for a specific line.

Finally if you have the proper rights for the user interface you can issue a flag as a false positive directly from the interface.

The reason why I recommend suppression of specific warnings is that it's a better practice to block a specific issue instead of using //NOSONAR and risk a Sonar issue creeping in your code by accident.

You can read more about this in the FAQ

Edit: 6/30/16 SonarQube is now called SonarLint

In case you are wondering how to find the squid number. Just click on the Sonar message (ex. Remove this method to simply inherit it.) and the Sonar issue will expand.

On the bottom left it will have the squid number (ex. squid:S1185 Maintainability > Understandability)

So then you can suppress it by @SuppressWarnings("squid:S1185")

In addition to the other answer, I would like to point out that this reasoning is also known as the De Morgan's law. It's actually more about mathematics than programming, but it is so fundamental that every programmer should know about it.

Your problem started like this:

enabled  = A and B
disabled = not ( A and B )

So far so good, but you went one step further and tried to remove the braces. And that's a little tricky, because you have to replace the and/&& with an or/||.

not ( A and B ) = not(A) OR not(B)

Or in a more mathematical notation:

I always keep this law in mind whenever I simplify conditions or work with probabilities.

Here I present an alternative way to detect a browser, based on feature availability.

To detect only IE, you can use this:

if(/*@cc_on!@*/false || typeof ScriptEngineMajorVersion === "function")
{
    //You are using IE>=4 (unreliable for IE11)
}
else
{
    //You are using other browser
}

To detect the most popular browsers:

if(/*@cc_on!@*/false || typeof ScriptEngineMajorVersion === "function")
{
    //You are using IE >= 4 (unreliable for IE11!!!)
}
else if(window.chrome)
{
    //You are using Chrome or Chromium
}
else if(window.opera)
{
    //You are using Opera >= 9.2
}
else if('MozBoxSizing' in document.body.style)
{
    //You are using Firefox or Firefox based >= 3.2
}
else if({}.toString.call(window.HTMLElement).indexOf('Constructor')+1)
{
    //You are using Safari >= 3.1
}
else
{
    //Unknown
}

This answer was updated because IE11 no longer supports conditional compilation (the /*@cc_on!@*/false trick).
You can check Did IE11 remove javascript conditional compilation? for more informations regarding this topic.
I've used the suggestion they presented there.
Alternatively, you can use typeof document.body.style.msTransform == "string" or document.body.style.msTransform !== window.undefined or even 'msTransform' in document.body.style.

In short, the original purpose was to make a field which will be submitted with form's submit. Sometimes, there were need to store some information in hidden field(for example, id of user) and submit it with form's submit.

From HTML September 22, 1995 specification

An INPUT element with `TYPE=HIDDEN' represents a hidden field.The user does not interact with this field; instead, the VALUE attribute specifies the value of the field. The NAME and VALUE attributes are required.

Just create a data.frame with 0 length variables

eg

nodata <- data.frame(x= numeric(0), y= integer(0), z = character(0))
str(nodata)

## 'data.frame':    0 obs. of  3 variables:
##  $ x: num 
##  $ y: int 
##  $ z: Factor w/ 0 levels: 

or to create a data.frame with 5 columns named a,b,c,d,e

nodata <- as.data.frame(setNames(replicate(5,numeric(0), simplify = F), letters[1:5]))

I ran into similar/same error message. In my case, I did not have the target DOM node which is to render the ReactJS component defined. Ensure the HTML target node is well defined with appropriate "id" or "name", along with other HTML attributes (suitable for your design need)

I found this answer when I was getting a similar error for nodeName after upgrading to Bootstrap 4. The issue was that the tabs didn't have the nav and nav-tab classes; adding those to the <ul> element fixed the issue.

Do you mean these hex values?

.glyphicon-asterisk:before{content:"\2a";}
.glyphicon-plus:before{content:"\2b";}
.glyphicon-euro:before{content:"\20ac";}
...

You can find these in glyphicons.css here:

http://netdna.bootstrapcdn.com/bootstrap/3.0.0/css/bootstrap-glyphicons.css

(If you only want to know the Glyphicons classes: http://getbootstrap.com/components/#glyphicons)

First you need to create package:

com.myCompany.executabe (src > right click > new > package).

Follow these steps to move the Java files to your new package.

1. Select the Java files
2. Right click
3. Refactor
4. Move
5. Select your preferred package

ref mimics (or behaves) as a global area just for two scopes:

• Caller
• Callee.

Add an empty typescript file to the typescript scripts folder (the location of your tsconfig file) to satisfy the typescript compiler.

Java projects are exported as Jar executables. When you wanna do a .exe file of a java project, what you can do is 'convert' the JAR to EXE (i remark that i putted between quotes convert because isn't exactly this).

From intelij you gonna be able to generate only the jar

Try following the next example : https://www.genuinecoder.com/convert-java-jar-to-exe/

Use forEach in combo with Object.entries().

const WALLPAPERS = [{
  WALLPAPER_KEY: 'wallpaper.image',
  WALLPAPER_VALID_KEY: 'wallpaper.image.valid',
}, {
  WALLPAPER_KEY: 'lockscreen.image',
  WALLPAPER_VALID_KEY: 'lockscreen.image.valid',
}];

WALLPAPERS.forEach((obj) => {
  for (const [key, value] of Object.entries(obj)) {
    console.log(`${key} - ${value}`);
  }
});

DECLARE @test nvarchar(100)

SET @test = 'Foreign Tax Credit - 1997'

SELECT @test, left(@test, charindex('-', @test) - 2) AS LeftString,
    right(@test, len(@test) - charindex('-', @test) - 1)  AS RightString

If you're using Java 8, the Arrays class provides a stream(int[] array) method which returns a sequential IntStream with the specified int array. It has also been overloaded for double and long arrays.

int [] arr = {1,2,3,4};
int sum = Arrays.stream(arr).sum(); //prints 10

It also provides a method stream(int[] array, int startInclusive, int endExclusive) which permits you to take a specified range of the array (which can be useful) :

int sum = Arrays.stream(new int []{1,2,3,4}, 0, 2).sum(); //prints 3

Finally, it can take an array of type T. So you can per example have a String which contains numbers as an input and if you want to sum them just do :

int sum = Arrays.stream("1 2 3 4".split("\\s+")).mapToInt(Integer::parseInt).sum();

var pattern = new RegExp((0|1)[0-9]\/[0-3][0-9]\/(19|20)[0-9]{2});
if(!testdate.match(pattern))
   return false;
else return true;

Immutable Object's state cannot be altered.

for example String.

String str= "abc";//a object of string is created
str  = str + "def";// a new object of string is created and assigned to str

When you use background-size: cover the background image will automatically be stretched to cover the entire container. Aspect ratio is maintained however, so you will always lose part of the image, unless the aspect ratio of the image and the element it is applied to are identical.

I see two ways you could solve this:

• Do not maintain the aspect ratio of the image by setting background-size: 100% 100% This will also make the image cover the entire container, but the ratio will not be maintained. Disadvantage is that this distorts your image, and therefore may look very weird, depending on the image. With the image you are using in the fiddle, I think you could get away with it though.

• You could also calculate and set the height of the element with javascript, based on its width, so it gets the same ratio as the image. This calculation would have to be done on load and on resize. It should be easy enough with a few lines of code (feel free to ask if you want an example). Disadvantage of this method is that your width may become very small (on mobile devices), and therfore the calculated height also, which may cause the content of the container to overflow. This could be solved by changing the size of the content as well or something, but it adds some complexity to the solution/

perhaps, you can first determine if the DOM does really exists,

function walkmydog() {
    //when the user starts entering
    var dom = document.getElementById('WallSearch');
    if(dom == null){
        alert('sorry, WallSearch DOM cannot be found');
        return false;    
    }

    if(dom.value.length == 0){
        alert("nothing");
    }
}

if (document.addEventListener){
    document.addEventListener("DOMContentLoaded", walkmydog, false);
}

This is much easier in pandas now with drop_duplicates and the keep parameter.

import pandas as pd
df = pd.DataFrame({"A":["foo", "foo", "foo", "bar"], "B":[0,1,1,1], "C":["A","A","B","A"]})
df.drop_duplicates(subset=['A', 'C'], keep=False)

Another approach, if you simply wish to print a PDF file programmatically, is to use the LPR command: http://www.microsoft.com/resources/documentation/windows/xp/all/proddocs/en-us/lpr.mspx?mfr=true

LPR is available on newer versions of Windows too (e.g. Vista/7), but you need to enable it in the Optional Windows Components.

For example:

Process.Start("LPR -S printerdnsalias -P raw C:\files\file.pdf");

You can also use the printer IP address instead of the alias.

This assumes that your printer supports PDF Direct Printing otherwise this will only work for PostScript and ASCII files. Also, the printer needs to have a network interface installed and you need to know it's IP address or alias.

It depends a bit on what you want:

A) If you want to specify which libraries to link to, you can use find_library to find libs and then use link_directories and target_link_libraries to.

Of course, it is often worth the effort to write a good find_package script, which nicely adds "imported" libraries with add_library( YourLib IMPORTED ) with correct locations, and platform/build specific pre- and suffixes. You can then simply refer to 'YourLib' and use target_link_libraries.

B) If you wish to specify particular linker-flags, e.g. '-mthreads' or '-Wl,--export-all-symbols' with MinGW-GCC, you can use CMAKE_EXE_LINKER_FLAGS. There are also two similar but undocumented flags for modules, shared or static libraries:

CMAKE_MODULE_LINKER_FLAGS
CMAKE_SHARED_LINKER_FLAGS
CMAKE_STATIC_LINKER_FLAGS

I too needed a rounded ImageView, I used the below code, you can modify it accordingly:

import android.content.Context;
import android.graphics.Bitmap;
import android.graphics.Bitmap.Config;
import android.graphics.Canvas;
import android.graphics.Color;
import android.graphics.Paint;
import android.graphics.PorterDuff.Mode;
import android.graphics.PorterDuffXfermode;
import android.graphics.Rect;
import android.graphics.drawable.BitmapDrawable;
import android.graphics.drawable.Drawable;
import android.util.AttributeSet;
import android.widget.ImageView;

public class RoundedImageView extends ImageView {

    public RoundedImageView(Context context) {
        super(context);
    }

    public RoundedImageView(Context context, AttributeSet attrs) {
        super(context, attrs);
    }

    public RoundedImageView(Context context, AttributeSet attrs, int defStyle) {
        super(context, attrs, defStyle);
    }

    @Override
    protected void onDraw(Canvas canvas) {

        Drawable drawable = getDrawable();

        if (drawable == null) {
            return;
        }

        if (getWidth() == 0 || getHeight() == 0) {
            return;
        }
        Bitmap b = ((BitmapDrawable) drawable).getBitmap();
        Bitmap bitmap = b.copy(Bitmap.Config.ARGB_8888, true);

        int w = getWidth();
        @SuppressWarnings("unused")
        int h = getHeight();

        Bitmap roundBitmap = getCroppedBitmap(bitmap, w);
        canvas.drawBitmap(roundBitmap, 0, 0, null);

    }

    public static Bitmap getCroppedBitmap(Bitmap bmp, int radius) {
        Bitmap sbmp;

        if (bmp.getWidth() != radius || bmp.getHeight() != radius) {
            float smallest = Math.min(bmp.getWidth(), bmp.getHeight());
            float factor = smallest / radius;
            sbmp = Bitmap.createScaledBitmap(bmp,
                    (int) (bmp.getWidth() / factor),
                    (int) (bmp.getHeight() / factor), false);
        } else {
            sbmp = bmp;
        }

        Bitmap output = Bitmap.createBitmap(radius, radius, Config.ARGB_8888);
        Canvas canvas = new Canvas(output);

        final String color = "#BAB399";
        final Paint paint = new Paint();
        final Rect rect = new Rect(0, 0, radius, radius);

        paint.setAntiAlias(true);
        paint.setFilterBitmap(true);
        paint.setDither(true);
        canvas.drawARGB(0, 0, 0, 0);
        paint.setColor(Color.parseColor(color));
        canvas.drawCircle(radius / 2 + 0.7f, radius / 2 + 0.7f,
                radius / 2 + 0.1f, paint);
        paint.setXfermode(new PorterDuffXfermode(Mode.SRC_IN));
        canvas.drawBitmap(sbmp, rect, rect, paint);

        return output;
    }

}

Try this code, this should work:

import platform
print(platform.python_version())

Take a look to SimpleDateFormat class that can parse a String and return a Date and the getTime method of Date class.

try: $(".highlight").removeClass("highlight");. By selecting $(".edgetoedge") you are only running functions at that level.

I use Telegram.Bot and got the ID the following way:

1. Add the bot to the channel
2. Run the bot
3. Write something into the channel (eg: /authenticate or foo)

Telegram.Bot:

private static async Task Main()
{
    var botClient = new TelegramBotClient("key");
    botClient.OnUpdate += BotClientOnOnUpdate;
    Console.ReadKey();
}

private static async void BotClientOnOnUpdate(object? sender, UpdateEventArgs e)
{
    var id = e.Update.ChannelPost.Chat.Id;
    await botClient.SendTextMessageAsync(new ChatId(id), $"Hello World! Channel ID is {id}");
}

Plain API:

This translates to the getUpdates method in the plain API, which has an array of Update which then contains channel_post.chat.id

For me, it was because I had temporarily excluded the file from the project. I merely included it in back in the project and then it worked.

You need to implement RefreshTokenProvider. First create class for RefreshTokenProvider ie.

public class ApplicationRefreshTokenProvider : AuthenticationTokenProvider
{
    public override void Create(AuthenticationTokenCreateContext context)
    {
        // Expiration time in seconds
        int expire = 5*60;
        context.Ticket.Properties.ExpiresUtc = new DateTimeOffset(DateTime.Now.AddSeconds(expire));
        context.SetToken(context.SerializeTicket());
    }

    public override void Receive(AuthenticationTokenReceiveContext context)
    {
        context.DeserializeTicket(context.Token);
    }
}

Then add instance to OAuthOptions.

OAuthOptions = new OAuthAuthorizationServerOptions
{
    TokenEndpointPath = new PathString("/authenticate"),
    Provider = new ApplicationOAuthProvider(),
    AccessTokenExpireTimeSpan = TimeSpan.FromSeconds(expire),
    RefreshTokenProvider = new ApplicationRefreshTokenProvider()
};

function sample() {
    alert("This is sample function");
}

$(function() {
    $("#button").click(function() {
        setTimeout(sample, 2000);
    });

});

jsFiddle.

If you want to encapsulate sample() there, wrap the whole thing in a self invoking function (function() { ... })().

Perhaps this could be another possible replace :

@Data
public class MyMap {
    @Delegate //lombok
    private HashMap<String, String> value;
}

Probably the easiest way to explore your ElasticSearch cluster is to use elasticsearch-head.

You can install it by doing:

cd elasticsearch/
./bin/plugin -install mobz/elasticsearch-head

Then (assuming ElasticSearch is already running on your local machine), open a browser window to:

http://localhost:9200/_plugin/head/

Alternatively, you can just use curl from the command line, eg:

Check the mapping for an index:

curl -XGET 'http://127.0.0.1:9200/my_index/_mapping?pretty=1' 

Get some sample docs:

curl -XGET 'http://127.0.0.1:9200/my_index/_search?pretty=1' 

See the actual terms stored in a particular field (ie how that field has been analyzed):

curl -XGET 'http://127.0.0.1:9200/my_index/_search?pretty=1'  -d '
 {
    "facets" : {
       "my_terms" : {
          "terms" : {
             "size" : 50,
             "field" : "foo"
          }
       }
    }
 }

UPDATE : Sense plugin in Marvel

By far the easiest way of writing curl-style commands for Elasticsearch is the Sense plugin in Marvel.

It comes with source highlighting, pretty indenting and autocomplete.

Note: Sense was originally a standalone chrome plugin but is now part of the Marvel project.

Since FFT is symmetric over it's centre, half the values are just enough.

import numpy as np
import matplotlib.pyplot as plt

fs = 30.0
t = np.arange(0,10,1/fs)
x = np.cos(2*np.pi*10*t)

xF = np.fft.fft(x)
N = len(xF)
xF = xF[0:N/2]
fr = np.linspace(0,fs/2,N/2)

plt.ion()
plt.plot(fr,abs(xF)**2)

Please see the comments.

        command = ["ping", "google.com"]
        sp = self.execute(command)
        status = sp.wait()  # will wait for sp to finish
        out, err = sp.communicate()
        print(out)
        return status # 0 is success else error

Here is sample code for LocalNotification that worked for my project.

Objective-C:

This code block in AppDelegate file :

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
    {
        [launchOptions valueForKey:UIApplicationLaunchOptionsLocalNotificationKey];
        // Override point for customization after application launch.
        return YES;
    }

    // This code block is invoked when application is in foreground (active-mode) 
 -(void)application:(UIApplication *)application didReceiveLocalNotification:(UILocalNotification *)notification {

        UIAlertView *notificationAlert = [[UIAlertView alloc] initWithTitle:@"Notification"    message:@"This local notification" 
        delegate:nil cancelButtonTitle:@"Ok" otherButtonTitles:nil, nil];

        [notificationAlert show];
       // NSLog(@"didReceiveLocalNotification");
    }

This code block in .m file of any ViewController:

-(IBAction)startLocalNotification {  // Bind this method to UIButton action
    NSLog(@"startLocalNotification");

    UILocalNotification *notification = [[UILocalNotification alloc] init];
    notification.fireDate = [NSDate dateWithTimeIntervalSinceNow:7];
    notification.alertBody = @"This is local notification!";
    notification.timeZone = [NSTimeZone defaultTimeZone];
    notification.soundName = UILocalNotificationDefaultSoundName;
    notification.applicationIconBadgeNumber = 10;

    [[UIApplication sharedApplication] scheduleLocalNotification:notification];    
}

The above code display an AlertView after time interval of 7 seconds when pressed on button that binds startLocalNotification If application is in background then it displays BadgeNumber as 10 and with default notification sound.

This code works fine for iOS 7.x and below but for iOS 8 it will prompt following error on console:

Attempting to schedule a local notification with an alert but haven't received permission from the user to display alerts

This means you need register for local notification. This can be achieved using:

if ([UIApplication instancesRespondToSelector:@selector(registerUserNotificationSettings:)]){

    [application registerUserNotificationSettings [UIUserNotificationSettings settingsForTypes:UIUserNotificationTypeAlert|UIUserNotificationTypeBadge|UIUserNotificationTypeSound categories:nil]];
}

You can also refer blog for local notification.

Swift:

You AppDelegate.swift file should look like this:

func application(application: UIApplication, didFinishLaunchingWithOptions launchOptions: [NSObject: AnyObject]?) -> Bool {    
    // Override point for customization after application launch.
    application.registerUserNotificationSettings(UIUserNotificationSettings(forTypes: UIUserNotificationType.Sound | UIUserNotificationType.Badge | UIUserNotificationType.Alert, categories: nil))

    return true
}

The swift file (say ViewController.swift) in which you want to create local notification should contain below code:

//MARK: - Button functions
func buttonIsPressed(sender: UIButton) {
    println("buttonIsPressed function called \(UIButton.description())")

    var localNotification = UILocalNotification()
    localNotification.fireDate = NSDate(timeIntervalSinceNow: 3)
    localNotification.alertBody = "This is local notification from Swift 2.0"
    localNotification.timeZone = NSTimeZone.localTimeZone()
    localNotification.repeatInterval = NSCalendarUnit.CalendarUnitMinute
    localNotification.userInfo = ["Important":"Data"];
    localNotification.soundName = UILocalNotificationDefaultSoundName
    localNotification.applicationIconBadgeNumber = 5
    localNotification.category = "Message"

    UIApplication.sharedApplication().scheduleLocalNotification(localNotification)
}


//MARK: - viewDidLoad

class ViewController: UIViewController {

    var objButton : UIButton!
    . . .

    override func viewDidLoad() {
        super.viewDidLoad()

        . . .

        objButton = UIButton.buttonWithType(.Custom) as? UIButton
        objButton.frame = CGRectMake(30, 100, 150, 40)
        objButton.setTitle("Click Me", forState: .Normal)
        objButton.setTitle("Button pressed", forState: .Highlighted)

        objButton.addTarget(self, action: "buttonIsPressed:", forControlEvents: .TouchDown)

        . . .
    }

    . . .
}

The way you use to work with Local Notification in iOS 9 and below is completely different in iOS 10.

Below screen grab from Apple release notes depicts this.

You can refer apple reference document for UserNotification.

Below is code for local notification:

Objective-C:

1. In App-delegate.h file use @import UserNotifications;

2. App-delegate should conform to UNUserNotificationCenterDelegate protocol

3. In didFinishLaunchingOptions use below code:

   UNUserNotificationCenter *center = [UNUserNotificationCenter currentNotificationCenter];
   [center requestAuthorizationWithOptions:(UNAuthorizationOptionBadge | UNAuthorizationOptionSound | UNAuthorizationOptionAlert)
          completionHandler:^(BOOL granted, NSError * _Nullable error) {
                 if (!error) {
                     NSLog(@"request authorization succeeded!");
                     [self showAlert];
                 }
   }];
   
   -(void)showAlert {
       UIAlertController *objAlertController = [UIAlertController alertControllerWithTitle:@"Alert" message:@"show an alert!" preferredStyle:UIAlertControllerStyleAlert];
   
       UIAlertAction *cancelAction = [UIAlertAction actionWithTitle:@"OK"
         style:UIAlertActionStyleCancel handler:^(UIAlertAction *action) {
           NSLog(@"Ok clicked!");
       }];
   
       [objAlertController addAction:cancelAction];
   
   
       [[[[[UIApplication sharedApplication] windows] objectAtIndex:0] rootViewController] presentViewController:objAlertController animated:YES completion:^{            
       }];
   
   }
   

4. Now create a button in any view controller and in IBAction use below code :

   UNMutableNotificationContent *objNotificationContent = [[UNMutableNotificationContent alloc] init];
   
   objNotificationContent.title = [NSString localizedUserNotificationStringForKey:@“Notification!” arguments:nil];
   
   objNotificationContent.body = [NSString localizedUserNotificationStringForKey:@“This is local notification message!“arguments:nil];
   
   objNotificationContent.sound = [UNNotificationSound defaultSound];
   
   // 4. update application icon badge number
   objNotificationContent.badge = @([[UIApplication sharedApplication] applicationIconBadgeNumber] + 1);
   
   // Deliver the notification in five seconds.
   UNTimeIntervalNotificationTrigger *trigger =  [UNTimeIntervalNotificationTrigger                                             triggerWithTimeInterval:10.f repeats:NO];       
   
   UNNotificationRequest *request = [UNNotificationRequest requestWithIdentifier:@“ten”                                                                            content:objNotificationContent trigger:trigger];
   
   // 3. schedule localNotification
   UNUserNotificationCenter *center = [UNUserNotificationCenter currentNotificationCenter];
   
   [center addNotificationRequest:request withCompletionHandler:^(NSError * _Nullable error) {
       if (!error) {
           NSLog(@“Local Notification succeeded“);
       } else {
           NSLog(@“Local Notification failed“);
       }
   }];
   

Swift 3:

1. In AppDelegate.swift file use import UserNotifications
2. Appdelegate should conform to UNUserNotificationCenterDelegate protocol

3. In didFinishLaunchingWithOptions use below code

   // Override point for customization after application launch.
   let center = UNUserNotificationCenter.current()
   center.requestAuthorization(options: [.alert, .sound]) { (granted, error) in
       // Enable or disable features based on authorization.
       if error != nil {
           print("Request authorization failed!")
       } else {
           print("Request authorization succeeded!")
           self.showAlert()
       }
   }
   
   
   func showAlert() {
       let objAlert = UIAlertController(title: "Alert", message: "Request authorization succeeded", preferredStyle: UIAlertControllerStyle.alert)
   
       objAlert.addAction(UIAlertAction(title: "OK", style: UIAlertActionStyle.default, handler: nil))
       //self.presentViewController(objAlert, animated: true, completion: nil)
   
       UIApplication.shared().keyWindow?.rootViewController?.present(objAlert, animated: true, completion: nil)
   }
   

4. Now create a button in any view controller and in IBAction use below code :

   let content = UNMutableNotificationContent()
   content.title = NSString.localizedUserNotificationString(forKey: "Hello!", arguments: nil)
   content.body = NSString.localizedUserNotificationString(forKey: "Hello_message_body", arguments: nil)
   content.sound = UNNotificationSound.default()
   content.categoryIdentifier = "notify-test"
   
   let trigger = UNTimeIntervalNotificationTrigger.init(timeInterval: 5, repeats: false)
   let request = UNNotificationRequest.init(identifier: "notify-test", content: content, trigger: trigger)
   
   let center = UNUserNotificationCenter.current()
   center.add(request)
   

This works well for me:

WifiConfiguration apConfig = null;
Method method = wifimanager.getClass().getMethod("setWifiApEnabled", WifiConfiguration.class, Boolean.TYPE);
method.invoke(wifimanager, apConfig, true);

First of all, the easiest way to run things at startup is to add them to the file /etc/rc.local.

Another simple way is to use @reboot in your crontab. Read the cron manpage for details.

However, if you want to do things properly, in addition to adding a script to /etc/init.d you need to tell ubuntu when the script should be run and with what parameters. This is done with the command update-rc.d which creates a symlink from some of the /etc/rc* directories to your script. So, you'd need to do something like:

update-rc.d yourscriptname start 2

However, real init scripts should be able to handle a variety of command line options and otherwise integrate to the startup process. The file /etc/init.d/README has some details and further pointers.

More preprocessor abuse:

#include <stdio.h>

#define A1(x,y) #x #y "0\n" #x #y "1\n" #x #y "2\n" #x #y "3\n" #x #y "4\n" #x #y "5\n" #x #y "6\n" #x #y "7\n" #x #y "8\n" #x #y "9\n"
#define A2(x) A1(x,1) A1(x,2) A1(x,3) A1(x,4) A1(x,5) A1(x,6) A1(x,7) A1(x,8) A1(x,9)
#define A3(x) A1(x,0) A2(x)
#define A4 A3(1) A3(2) A3(3) A3(4) A3(5) A3(6) A3(7) A3(8) A3(9)
#define A5 "1\n2\n3\n4\n5\n6\n7\n8\n9\n" A2() A4 "1000\n"

int main(int argc, char *argv[]) {
    printf(A5);
    return 0;
}

I feel so dirty; I think I'll go shower now.

Predicate<Client> hasSameNameAsOneUser = 
    c -> users.stream().anyMatch(u -> u.getName().equals(c.getName()));

return clients.stream()
              .filter(hasSameNameAsOneUser)
              .collect(Collectors.toList());

But this is quite inefficient, because it's O(m * n). You'd better create a Set of acceptable names:

Set<String> acceptableNames = 
    users.stream()
         .map(User::getName)
         .collect(Collectors.toSet());

return clients.stream()
              .filter(c -> acceptableNames.contains(c.getName()))
              .collect(Collectors.toList());

Also note that it's not strictly equivalent to the code you have (if it compiled), which adds the same client twice to the list if several users have the same name as the client.

You could do this:

String strz[] = strs.toArray(String[strs.size()]);
String theFirstOne = strz[0];

The javadoc for Collection gives the following caveat wrt ordering of the elements of the array:

If this collection makes any guarantees as to what order its elements are returned by its iterator, this method must return the elements in the same order.

In Python we can use the __str__() method.

We can override it in our class like this:

class User: 

    firstName = ''
    lastName = ''
    ...

    def __str__(self):
        return self.firstName + " " + self.lastName

and when running

print(user)

it will call the function __str__(self) and print the firstName and lastName

Here is simple example. you can use it like

wget -q -O - http://example.com/backup >/dev/null 2>&1

and in start you can add your option like (*****). Its up to your system requirements either you want to run it every minute or hours etc.

<?php
session_start();
if($_SESSION['login'] != 'ok')
    header('location: /dashboard.php?login=0');

if(isset($_SESSION['last-activity']) && time() - $_SESSION['last-activity'] > 600) {
    // session inactive more than 10 min
    header('location: /logout.php?timeout=1');
}

$_SESSION['last-activity'] = time(); // update last activity time stamp

if(time() - $_SESSION['created'] > 600) {
    // session started more than 10 min ago
    session_regenerate_id(true); // change session id and invalidate old session
    $_SESSION['created'] = time(); // update creation time
}
?>

N.B. - this question and answer relate to the 2000 version of SQL Server. In later versions, the restriction on INSERT INTO @table_variable ... EXEC ... were lifted and so it doesn't apply for those later versions.

You'll have to switch to a temp table:

CREATE TABLE #tmp (code varchar(50), mount money)
DECLARE @q nvarchar(4000)
SET @q = 'SELECT coa_code, amount FROM T_Ledger_detail'

INSERT INTO  #tmp (code, mount)
EXEC sp_executesql (@q)

SELECT * from #tmp

From the documentation:

A table variable behaves like a local variable. It has a well-defined scope, which is the function, stored procedure, or batch in which it is declared.

Within its scope, a table variable may be used like a regular table. It may be applied anywhere a table or table expression is used in SELECT, INSERT, UPDATE, and DELETE statements. However, table may not be used in the following statements:

INSERT INTO table_variable EXEC stored_procedure

SELECT select_list INTO table_variable statements.

You are having this problem because you are attempting to console log app.address() before the connection has been made. You just have to be sure to console log after the connection is made, i.e. in a callback or after an event signaling that the connection has been made.

Fortunately, the 'listening' event is emitted by the server after the connection is made so just do this:

var express = require('express');
var http = require('http');

var app = express();
var server = http.createServer(app);

app.get('/', function(req, res) {
    res.send("Hello World!");
});

server.listen(3000, 'localhost');
server.on('listening', function() {
    console.log('Express server started on port %s at %s', server.address().port, server.address().address);
});

This works just fine in nodejs v0.6+ and Express v3.0+.

in swift 4 to convert to url use URL

let fileUrl = URL.init(fileURLWithPath: filePath)

or

let fileUrl = URL(fileURLWithPath: filePath)

Note that apart from rows and columns there is a number of channels and type. When it is clear what type is, the channels can act as an extra dimension as in CV_8UC3 so you would address a matrix as

uchar a = M.at<Vec3b>(y, x)[i];

So the size in terms of elements of elementary type is M.rows * M.cols * M.cn

To find the max element one can use

Mat src;
double minVal, maxVal;
minMaxLoc(src, &minVal, &maxVal);

I think now, the best practice is use display: inline-block;

look like this demo: https://jsfiddle.net/vjLw1z7w/

EDIT (02/2021):

Best practice now may be to using display: flex; flex-wrap: wrap; on div container and flex-basis: XX%; on div

look like this demo: https://jsfiddle.net/42L1emus/1/

It depends on the nature of your application. And, since you did not describe it in great detail, it is an impossible question to answer. I find Backbone to be the easiest, but I work in Angular all day. Performance is more up to the coder than the framework, in my opinion.

Are you doing heavy DOM manipulation? I would use jQuery and Backbone.

Very data driven app? Angular with its nice data binding.

Game programming? None - direct to canvas; maybe a game engine.

A rather nice addition to @MartijnPieters answer is to get back a dictionary sorted by occurrence since Collections.most_common only returns a tuple. I often couple this with a json output for handy log files:

from collections import Counter, OrderedDict

x = Counter({'a':5, 'b':3, 'c':7})
y = OrderedDict(x.most_common())

With the output:

OrderedDict([('c', 7), ('a', 5), ('b', 3)])
{
  "c": 7, 
  "a": 5, 
  "b": 3
}

I know this is an old post but I recently ran into a very similar problem. Unfortunately I wasn't able to use any of the alter database commands because an exclusive lock couldn't be placed. But I was never able to find an open connection to the db. I eventually had to forcefully delete the health state of the database to force it into a restoring state instead of in recovery.

Maybe I'm missing something, but why try to parse the file? Why not just load the YAML and examine the object(s) that result?

If your sample YAML is in some.yml, then this:

require 'yaml'
thing = YAML.load_file('some.yml')
puts thing.inspect

gives me

{"javascripts"=>[{"fo_global"=>["lazyload-min", "holla-min"]}]}

#include <iostream>
using namespace std;

int main () {
    bool boolean;
    boolean = true;

    if (boolean == true) {

        cout << "press any key to continue";
        cin >> boolean;

    }
    return 0;
}

I had such crash on Samsung devices even though the activity did use Theme.AppCompat. The root cause was related to weird optimizations on Samsung side:

- if one activity of your app has theme not inherited from Theme.AppCompat
- and it has also `android:launchMode="singleTask"`
- then all the activities that are launched from it will share the same Theme

My solution was just removing android:launchMode="singleTask"

Try JScrambler. I gave it a spin recently and was impressed by it. It provides a set of templates for obfuscation with predefined settings for those who don't care much about the details and just want to get it done quickly. You can also create custom obfuscation by choosing whatever transformations/techniques you want.

my_awesome_script.setAttribute('src','http://example.com/site.js');

document.head.appendChild(my_awesome_script);

Having read the above answers i found that for my situation the following fixed the issue.

This threw the error

myButton.setOnClickListener(new OnClickListener(){
    public void onClick(View v) {
        MyDialogue dialog = new MyDialogue(getApplicationContext());
        dialog.show();              
    }
});

Based on the previous answers that suggested the context was the wrong one, i changed the getApplicationContext() to retrieve the context from the View passed in to the buttons onClick method.

myButton.setOnClickListener(new OnClickListener(){
    public void onClick(View v) {
        MyDialogue dialog = new MyDialogue(v.getContext());
        dialog.show();              
    }
});

I don't fully understand the workings of Java so i could be wrong, but I'm guessing that for my specific situation the cause could have been related to the fact that the above snippet was defined in an Abstract Activity class; inherited and used by many Activities, perhaps that contributed to the fact that getApplicationContext() doesn't return a valid context?? (Just a guess).

You need to create an event handler for the user control that is raised when an event from within the user control is fired. This will allow you to bubble the event up the chain so you can handle the event from the form.

When clicking Button1 on the UserControl, i'll fire Button1_Click which triggers UserControl_ButtonClick on the form:

User control:

[Browsable(true)] [Category("Action")] 
[Description("Invoked when user clicks button")]
public event EventHandler ButtonClick;

protected void Button1_Click(object sender, EventArgs e)
{
    //bubble the event up to the parent
    if (this.ButtonClick!= null)
        this.ButtonClick(this, e);               
}

Form:

UserControl1.ButtonClick += new EventHandler(UserControl_ButtonClick);

protected void UserControl_ButtonClick(object sender, EventArgs e)
{
    //handle the event 
}

Notes:

• Newer Visual Studio versions suggest that instead of if (this.ButtonClick!= null) this.ButtonClick(this, e); you can use ButtonClick?.Invoke(this, e);, which does essentially the same, but is shorter.

• The Browsable attribute makes the event visible in Visual Studio's designer (events view), Category shows it in the "Action" category, and Description provides a description for it. You can omit these attributes completely, but making it available to the designer it is much more comfortable, since VS handles it for you.

I presume you mean via SSMS?

For a SQL Server Instance:

SELECT SERVERPROPERTY('productversion'), 
       SERVERPROPERTY ('productlevel'), 
       SERVERPROPERTY ('edition')

For a SQL Server Installation:

Select @@Version

I think you should call the super.draw() method first before you do anything in surfaceView's draw method.

Basic:

string[] myString = new string[]{"string1", "string2"};

or

string[] myString = new string[4];
myString[0] = "string1"; // etc.

Advanced: From a List

list<string> = new list<string>(); 
//... read this in from somewhere
string[] myString = list.ToArray();

From StringCollection

StringCollection sc = new StringCollection();
/// read in from file or something
string[] myString = sc.ToArray();

An alternative would be to set a variable, and check whether it is defined:

SET ARG=%1
IF DEFINED ARG (echo "It is defined: %1") ELSE (echo "%%1 is not defined")

Unfortunately, using %1 directly with DEFINED doesn't work.

No. Java does not have this feature. You'd have to create your String using a StringBuilder, and a loop of some sort.

If it doesn't show up in your package manager (i.e. apt-cache search texinfo) and even apt-file search bin/makeinfo is no help, you may have to enable non-free/restricted packages for your package manager.

For ubuntu, sudo $EDITOR /etc/apt/sources.list and add restricted.

deb http://archive.ubuntu.com/ubuntu bionic main restricted universe multiverse
deb http://archive.ubuntu.com/ubuntu bionic-security main
deb http://archive.ubuntu.com/ubuntu bionic-updates main

For debian, sudo $EDITOR /etc/apt/sources.list and add non-free. You can even have preferences on package level if you don't want to clutter the package db with non-free stuff.

After a sudo apt-get udpate you should find the required package.

Any mature enough SQL database should be able to execute that just as effectively as the equivalent JOIN. Use whatever is more readable to you.

You need to modify the config-db.php and set your password to the password you gave to the user root, or else if he has no password leave as this ''.

Swift 4 parses JSON much more elegantly. Just adopt the codable protocol for your structure as per this simplified example:

struct Business: Codable {
    let id: Int
    let name: String
}

To parse the JSON array, you tell the decoder what the objects of the data array are

let parsedData = decoder.decode([Business].self, from: data)

Here's a full working example:

import Foundation

struct Business: Codable {
    let id: Int
    let name: String
}

// Generating the example JSON data: 
let originalObjects = [Business(id: 0, name: "A"), Business(id: 1, name: "B")]
let encoder = JSONEncoder()
let data = try! encoder.encode(originalObjects)

// Parsing the data: 
let decoder = JSONDecoder()
let parsedData = try! decoder.decode([Business].self, from: data)

This answer may help if: 1) your site used to work with Windows authentication before upgrading to Visual Studio 2015 and 2) and your site is attempting to load /login.aspx (even though there is no such file on your site).

Add the following two lines to the appSettingssection of your site's Web.config.

<add key="autoFormsAuthentication" value="false" />
<add key="enableSimpleMembership" value="false"/>

Two-way binding means that any data-related changes affecting the model are immediately propagated to the matching view(s), and that any changes made in the view(s) (say, by the user) are immediately reflected in the underlying model. When app data changes, so does the UI, and conversely.

This is a very solid concept to build a web application on top of, because it makes the "Model" abstraction a safe, atomic data source to use everywhere within the application. Say, if a model, bound to a view, changes, then its matching piece of UI (the view) will reflect that, no matter what. And the matching piece of UI (the view) can safely be used as a mean of collecting user inputs/data, so as to maintain the application data up-to-date.

A good two-way binding implementation should obviously make this connection between a model and some view(s) as simple as possible, from a developper point of view.

It is then quite untrue to say that Backbone does not support two-way binding: while not a core feature of the framework, it can be performed quite simply using Backbone's Events though. It costs a few explicit lines of code for the simple cases; and can become quite hazardous for more complex bindings. Here is a simple case (untested code, written on the fly just for the sake of illustration):

Model = Backbone.Model.extend
  defaults:
    data: ''

View = Backbone.View.extend
  template: _.template("Edit the data: <input type='text' value='<%= data %>' />")

  events:
    # Listen for user inputs, and edit the model.
    'change input': @setData

  initialize: (options) ->
    # Listen for model's edition, and trigger UI update
    @listenTo @model, 'change:data', @render

  render: ->
    @$el.html @template(@model.attributes)
    @

  setData: (e) =>
    e.preventDefault()
    @model.set 'data', $(e.currentTarget).value()

model: new Model()
view = new View {el: $('.someEl'), model: model}

This is a pretty typical pattern in a raw Backbone application. As one can see, it requires a decent amount of (pretty standard) code.

AngularJS and some other alternatives (Ember, Knockout…) provide two-way binding as a first-citizen feature. They abstract many edge-cases under some DSL, and do their best at integrating two-way binding within their ecosystem. Our example would look something like this with AngularJS (untested code, see above):

<div ng-app="app" ng-controller="MainCtrl">
  Edit the data:
  <input name="mymodel.data" ng-model="mymodel.data">
</div>

angular.module('app', [])
  .controller 'MainCtrl', ($scope) ->
    $scope.mymodel = {data: ''}

Rather short!

But, be aware that some fully-fledged two-way binding extensions do exist for Backbone as well (in raw, subjective order of decreasing complexity): Epoxy, Stickit, ModelBinder…

One cool thing with Epoxy, for instance, is that it allows you to declare your bindings (model attributes <-> view's DOM element) either within the template (DOM), or within the view implementation (JavaScript). Some people strongly dislike adding "directives" to the DOM/template (such as the ng-* attributes required by AngularJS, or the data-bind attributes of Ember).

Taking Epoxy as an example, one can rework the raw Backbone application into something like this (…):

Model = Backbone.Model.extend
  defaults:
    data: ''

View = Backbone.Epoxy.View.extend
  template: _.template("Edit the data: <input type='text' />")
  # or, using the inline form: <input type='text' data-bind='value:data' />

  bindings:
    'input': 'value:data'

  render: ->
    @$el.html @template(@model.attributes)
    @

model: new Model()
view = new View {el: $('.someEl'), model: model}

All in all, pretty much all "mainstream" JS frameworks support two-way binding. Some of them, such as Backbone, do require some extra work to make it work smoothly, but those are the same which do not enforce a specific way to do it, to begin with. So it is really about your state of mind.

Also, you may be interested in Flux, a different architecture for web applications promoting one-way binding through a circular pattern. It is based on the concept of fast, holistic re-rendering of UI components upon any data change to ensure cohesiveness and make it easier to reason about the code/dataflow. In the same trend, you might want to check the concept of MVI (Model-View-Intent), for instance Cycle.

This will remove the last character contained in your COMPANY_NAME var regardless if it is or not a semicolon:

echo "$COMPANY_NAME" | rev | cut -c 2- | rev

Another simple solution for this case using jQuery. Keep in mind it's not a good practice to use inline javascript.

JsFiddle

I've added IDs to html on the total price and on the buttons. Here is the jQuery.

$('#two').click(function(){
    $('#count').val('2');
    $('#total').text('Product price: $1000');
});

$('#four').click(function(){
    $('#count').val('4');
    $('#total').text('Product price: $2000');
});

// on your branch that holds the commit you want to pass
$ git log
// copy the commit hash found
$ git checkout [branch that will copy the commit]
$ git reset --hard [hash of the commit you want to copy from the other branch]
// remove the [brackets]

I solved this problem by changing my application package name according to signature certificate details. At first I created application with com.foo.xyz but my certificate organization was 'bar'. So I change my package name to com.bar.xyz and now there is no google play protect warning!

As of PowerShell 2, simple:

$recipients = $addresses -split "; "

Note that the right hand side is actually a case-insensitive regular expression, not a simple match. Use csplit to force case-sensitivity. See about_Split for more details.

Basically in JDBC most of these properties are not configurable in the API like that, rather they depend on implementation. The way JDBC handles this is by allowing the connection URL to be different per vendor.

So what you do is register the driver so that the JDBC system can know what to do with the URL:

 DriverManager.registerDriver((Driver) Class.forName("com.mysql.jdbc.Driver").newInstance());

Then you form the URL:

 String url = "jdbc:mysql://[host][,failoverhost...][:port]/[database][?propertyName1][=propertyValue1][&propertyName2][=propertyValue2]"

And finally, use it to get a connection:

 Connection c = DriverManager.getConnection(url);

In more sophisticated JDBC, you get involved with connection pools and the like, and application servers often have their own way of registering drivers in JNDI and you look up a DataSource from there, and call getConnection on it.

In terms of what properties MySQL supports, see here.

EDIT: One more thought, technically just having a line of code which does Class.forName("com.mysql.jdbc.Driver") should be enough, as the class should have its own static initializer which registers a version, but sometimes a JDBC driver doesn't, so if you aren't sure, there is little harm in registering a second one, it just creates a duplicate object in memeory.

A simple Expect script:

File Remotelogin.exp

    #!/usr/bin/expect
    set user [lindex $argv 1]
    set ip [lindex $argv 0]
    set password [lindex $argv 2]
    spawn ssh $user@$ip
    expect "password"
    send "$password\r"
    interact

Example:

./Remotelogin.exp <ip> <user name> <password>

var cumulativeOffset = function(element) {
    var top = 0, left = 0;
    do {
        top += element.offsetTop  || 0;
        left += element.offsetLeft || 0;
        element = element.offsetParent;
    } while(element);

    return {
        top: top,
        left: left
    };
};

(Method shamelessly stolen from PrototypeJS; code style, variable names and return value changed to protect the innocent)

Using either a float or a double value in a C expression will result in a value that is a double anyway, so printf can't tell the difference. Whereas a pointer to a double has to be explicitly signalled to scanf as distinct from a pointer to float, because what the pointer points to is what matters.

Although cursors usually considered horrible evil I believe this is a case for FAST_FORWARD cursor - the closest thing you can get to FOREACH in TSQL.

Find your stopped container id

docker ps -a

Commit the stopped container:

This command saves modified container state into a new image user/test_image

docker commit $CONTAINER_ID user/test_image

Start/run with a different entry point:

docker run -ti --entrypoint=sh user/test_image

Entrypoint argument description: https://docs.docker.com/engine/reference/run/#/entrypoint-default-command-to-execute-at-runtime

Note:

Steps above just start a stopped container with the same filesystem state. That is great for a quick investigation. But environment variables, network configuration, attached volumes and other staff is not inherited, you should specify all these arguments explicitly.

Steps to start a stopped container have been borrowed from here: (last comment) https://github.com/docker/docker/issues/18078

First way: JOIN:

get people with multiple countries:

SELECT u1.user_id 
FROM users u1
JOIN users u2
on u1.user_id  = u2.user_id 
AND u1.ancestry <> u2.ancestry

Get people from 2 specific countries:

SELECT u1.user_id 
FROM users u1
JOIN users u2
on u1.user_id  = u2.user_id 
WHERE u1.ancestry = 'Germany'
AND u2.ancestry = 'France'

For 3 countries... join three times. To only get the result(s) once, distinct.

Second way: GROUP BY

This will get users which have 3 lines (having...count) and then you specify which lines are permitted. Note that if you don't have a UNIQUE KEY on (user_id, ancestry), a user with 'id, england' that appears 3 times will also match... so it depends on your table structure and/or data.

SELECT user_id 
FROM users u1
WHERE ancestry = 'Germany'
OR ancestry = 'France'
OR ancestry = 'England'
GROUP BY user_id
HAVING count(DISTINCT ancestry) = 3

For example:

My file path:

C:\...\sdk\extras\google\usb_driver\android_winusb.inf

My data to paste:

;Tablet PC

%SingleAdbInterface%        = USB_Install, USB\VID_18D1&PID_0003&MI_01

%CompositeADBInterface%     = USB_Install, USB\VID_18D1&PID_0003&REV_0230&MI_01

The easiest way to insert html blocks is to use template strings (backticks). It will also allow you to insert dynamic content via ${...}:

document.getElementById("log-menu").innerHTML = `
            <a href="#"> 
               ${data.user.email}
            </a>
            <div class="dropdown-menu p-3 dropdown-menu-right">
                <div class="form-group">
                    <label for="email1">Logged in as:</label>
                    <p>${data.user.email}</p>
                </div>
                <button onClick="getLogout()" ">Sign out</button>
            </div>
    `

I had the same problem myself.

Visual Studio 2013 only told me that it couldn't reference to it, and it couldn't find the metadata. When I opened my solution (which has multiple projects in it) it said that I was using projects lower than the framework version of one of my projects.

So I switched everything to version 4.5, and it worked again.

There is a property in <Button> that is android:textAllCaps="false" that make characters in which you want in your own Small and caps. By Default its became True so write this code and make textAllCaps=false then you can write text on button in small and Caps letter as per your requirement. Complete code for a Button which allow use to write letters as per our requirement.

 <Button
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            android:id="@+id/btnLogin"
            android:text="Login for Chat"
            android:textAllCaps="false"/>

You can use np.logaddexp (which implements the idea in @gg349's answer):

In [33]: d = np.array([[1089, 1093]])

In [34]: e = np.array([[1000, 4443]])

In [35]: log_res = np.logaddexp(-3*d[0,0], -3*d[0,1]) - np.logaddexp(-3*e[0,0], -3*e[0,1])

In [36]: log_res
Out[36]: -266.99999385580668

In [37]: res = exp(log_res)

In [38]: res
Out[38]: 1.1050349147204485e-116

Or you can use scipy.special.logsumexp:

In [52]: from scipy.special import logsumexp

In [53]: res = np.exp(logsumexp(-3*d) - logsumexp(-3*e))

In [54]: res
Out[54]: 1.1050349147204485e-116

Use either:

balancePanel.Left = optionsPanel.Location.X;

or

balancePanel.Location = new Point(optionsPanel.Location.X, balancePanel.Location.Y);

See the documentation of Location:

Because the Point class is a value type (Structure in Visual Basic, struct in Visual C#), it is returned by value, meaning accessing the property returns a copy of the upper-left point of the control. So, adjusting the X or Y properties of the Point returned from this property will not affect the Left, Right, Top, or Bottom property values of the control. To adjust these properties set each property value individually, or set the Location property with a new Point.

Largest table I've encountered on SQL Server 8 on Windows2003 was 799 million with 5 columns. But whether or not it's good will is to be measured against the SLA and usage case - e.g. load 50-100,000,000 records and see if it still works.

javac (or java during runtime) looks for the classes being imported in the classpath. If they are not there in the classpath then classnotfound exceptions are thrown.

classpath is just like the path variable in a shell, which is used by the shell to find a command or executable.

Entire directories or individual jar files can be put in the classpath. Also, yes a classpath can perhaps include a path which is not local but is somewhere on the internet. Please read more about classpath to resolve your doubts.

As promised, here is my Cairo version. I scripted it with Lua, using lfs to walk the directories. I love these little challenges, as they allow me to explore APIs I wanted to dig for quite some time...
lfs and LuaCairo are both cross-platform, so it should work on other systems (tested on French WinXP Pro SP3).

I made a first version drawing file names as I walked the tree. Advantage: no memory overhead. Inconvenience: I have to specify the image size beforehand, so listings are likely to be cut off.

So I made this version, first walking the directory tree, storing it in a Lua table. Then, knowing the number of files, creating the canvas to fit (at least vertically) and drawing the names.
You can easily switch between PNG rendering and SVG one. Problem with the latter: Cairo generates it at low level, drawing the letters instead of using SVG's text capability. Well, at least, it guarantees accurate rending even on systems without the font. But the files are bigger... Not really a problem if you compress it after, to have a .svgz file.
Or it shouldn't be too hard to generate the SVG directly, I used Lua to generate SVG in the past.

Of course, you can change the styles. I didn't draw the connection lines, I didn't saw it as necessary. I might add them optionally later.

Create a new style

<style name="my_dialog_theme" parent="ThemeOverlay.AppCompat.Dialog">
    <item name="colorAccent">@color/colorAccent</item>                   <!--header background-->
    <item name="android:windowBackground">@color/colorPrimary</item>     <!--calendar background-->
    <item name="android:colorControlActivated">@color/colorAccent</item> <!--selected day-->
    <item name="android:textColorPrimary">@color/colorPrimaryText</item> <!--days of the month-->
    <item name="android:textColorSecondary">@color/colorAccent</item>    <!--days of the week-->
</style>

Then initialize the dialog

Calendar mCalendar = new GregorianCalendar();
mCalendar.setTime(new Date());

new DatePickerDialog(mContext, R.style.my_dialog_theme, new DatePickerDialog.OnDateSetListener() {
    @Override
    public void onDateSet(DatePicker view, int year, int monthOfYear, int dayOfMonth) {
        //do something with the date
    }
}, mCalendar.get(Calendar.YEAR), mCalendar.get(Calendar.MONTH), mCalendar.get(Calendar.DAY_OF_MONTH)).show();

Result:

You need to redefine the unnamed struct during &Configuration{}

package main

import "fmt"

type Configuration struct {
    Val   string
    Proxy struct {
        Address string
        Port    string
    }
}

func main() {

    c := &Configuration{
        Val: "test",
        Proxy: struct {
            Address string
            Port    string
        }{
            Address: "127.0.0.1",

Ooor you just create your own ListIterator:

public final class SparseArrayIterator<E> implements ListIterator<E> {

private final SparseArray<E> array;
private int cursor;
private boolean cursorNowhere;

/**
 * @param array
 *            to iterate over.
 * @return A ListIterator on the elements of the SparseArray. The elements
 *         are iterated in the same order as they occur in the SparseArray.
 *         {@link #nextIndex()} and {@link #previousIndex()} return a
 *         SparseArray key, not an index! To get the index, call
 *         {@link android.util.SparseArray#indexOfKey(int)}.
 */
public static <E> ListIterator<E> iterate(SparseArray<E> array) {
    return iterateAt(array, -1);

 * @param key
 *            to start the iteration at. {@link android.util.SparseArray#indexOfKey(int)}

If the functions are exposed - non-member, public or protected - then the caller should know about them, and the default values must be in the header.

If the functions are private and out-of-line, then it does make sense to put the defaults in the implementation file because that allows changes that don't trigger client recompilation (a sometimes serious issue for low-level libraries shared in enterprise scale development). That said, it is definitely potentially confusing, and there is documentation value in presenting the API in a more intuitive way in the header, so pick your compromise - though consistency's the main thing when there's no compelling reason either way.

I just found a solution for this. In my case, i was using TabBarViewController, A just uncheck the option 'Adjust Scroll View Insets'. Issues goes away. https://i.stack.imgur.com/vRNfV.png

You can redirect stdout into a file "output.txt":

import sys
sys.stdout = open('output.txt','wt')
print ("Hello stackoverflow!")
print ("I have a question.")

I'm not really sure if this adds anything but,

Caller saved means that the caller has to save the registers because they will be clobbered in the call and have no choice but to be left in a clobbered state after the call returns (for instance, the return value being in eax for cdecl. It makes no sense for the return value to be restored to the value before the call by the callee, because it is a return value).

Callee saved means that the callee has to save the registers and then restore them at the end of the call because they have the guarantee to the caller of containing the same values after the function returns, and it is possible to restore them, even if they are clobbered at some point during the call.

The issue with the above definition though is that for instance on Wikipedia cdecl, it says eax, ecx and edx are caller saved and rest are callee saved, this suggests that the caller must save all 3 of these registers, when it might not if none of these registers were used by the caller in the first place. In which case caller 'saved' becomes a misnomer, but 'call clobbered' still correctly applies. This is the same with 'the rest' being called callee saved. It implies that all other x86 registers will be saved and restored by the callee when this is not the case if some of the registers are never used in the call anyway. With cdecl, eax:edx may be used to return a 64 bit value. I'm not sure why ecx is also caller saved if needed, but it is.

also you can open more than two page try this

`<a href="http://www.microsoft.com" target="_blank" onclick="window.open('http://www.google.com'); window.open('http://www.yahoo.com');">Click Here</a>`

Try these

 String appDirectoryName = getResources().getString(R.string.app_name);
    File directory = new File(Environment.getExternalStorageDirectory().getAbsolutePath() + "/" + getResources().getString(R.string.app_name));
    directory.mkdirs();
    File[] fList = directory.listFiles();
    int a = 1;
    for (int x = 0; x < fList.length; x++) {

        //txt.setText("You Have Capture " + String.valueOf(a) + " Photos");
        a++;
    }
    //get all the files from a directory
    for (File file : fList) {
        if (file.isFile()) {
            list.add(new ModelClass(file.getName(), file.getAbsolutePath()));
        }
    }

You can also use simply exit().

Keep in mind that sys.exit(), exit(), quit(), and os._exit(0) kill the Python interpreter. Therefore, if it appears in a script called from another script by execfile(), it stops execution of both scripts.

See "Stop execution of a script called with execfile" to avoid this.

This is an addendum to @endy-tjahjono's solution.

I ended up not being able to get the value of uploadme from the scope. Even though uploadme in the HTML was visibly updated by the directive, I could still not access its value by $scope.uploadme. I was able to set its value from the scope, though. Mysterious, right..?

As it turned out, a child scope was created by the directive, and the child scope had its own uploadme.

The solution was to use an object rather than a primitive to hold the value of uploadme.

In the controller I have:

$scope.uploadme = {};
$scope.uploadme.src = "";

and in the HTML:

 <input type="file" fileread="uploadme.src"/>
 <input type="text" ng-model="uploadme.src"/>

There are no changes to the directive.

Now, it all works like expected. I can grab the value of uploadme.src from my controller using $scope.uploadme.

You need to use convert in order by as well:

SELECT  Convert(varchar,A.InsertDate,103) as Tran_Date
order by Convert(varchar,A.InsertDate,103)

Are you running this from within an X11 environment? You can use a terminal window, but it has to be within X (either after a graphical login, or by running startx).

If you're already within a graphical environment, try export DISPLAY=:0 for bash like shells (bash, sh, etc) or setenv DISPLAY :0 for C shell based shells (csh, tcsh, etc)

If you've connected from another machine via SSH, you use the -X option to display the graphical interface on the machine you're sitting at (provided there's an X server running there (such as xming for windows, and your standard Linux X server).

Use $http Interceptor

By using an $http interceptor you can send headers to Back-end or the other way around and do your checks that way.

Great article on $http interceptors

Example:

$httpProvider.interceptors.push(function ($q) {
        return {
            'response': function (response) {

                // TODO Create check for user authentication. With every request send "headers" or do some other check
                return response;
            },
            'responseError': function (reject) {

                // Forbidden
                if(reject.status == 403) {
                    console.log('This page is forbidden.');
                    window.location = '/';
                // Unauthorized
                } else if(reject.status == 401) {
                    console.log("You're not authorized to view this page.");
                    window.location = '/';
                }

                return $q.reject(reject);
            }
        };
    });

Put this in your .config or .run function.

You need to make the decode function return an array by passing in the true parameter.

json_decode(file_get_contents($file),true);

$(document).ready(function() {_x000D_
  $("a").click(function(event) {_x000D_
    var myClass = $(this).attr("class");_x000D_
    var myId = $(this).attr('id');_x000D_
    alert(myClass + " " + myId);_x000D_
  });_x000D_
})

<html>_x000D_
_x000D_
<head>_x000D_
  <script type="text/javascript" src="http://code.jquery.com/jquery-1.7.2.min.js"></script>_x000D_
</head>_x000D_
_x000D_
<body>_x000D_
  <a href="#" id="kana1" class="konbo">click me 1</a>_x000D_
  <a href="#" id="kana2" class="kinta">click me 2</a>_x000D_
</body>_x000D_
_x000D_
</html>

This works for me. There is no event.target.class function in jQuery.

I solved this issue by using sudo ie

sudo yarn start

or

sudo npm start

There's no fast way to retrieve attributes. But code ought to look like this (credit to Aaronaught):

var t = typeof(YourClass);
var pi = t.GetProperty("Id");
var hasIsIdentity = Attribute.IsDefined(pi, typeof(IsIdentity));

If you need to retrieve attribute properties then

var t = typeof(YourClass);
var pi = t.GetProperty("Id");
var attr = (IsIdentity[])pi.GetCustomAttributes(typeof(IsIdentity), false);
if (attr.Length > 0) {
    // Use attr[0], you'll need foreach on attr if MultiUse is true
}

Starting with .Net 4.5 you can use Task.Run to simply start an action:

void Foo(string args){}
...
Task.Run(() => Foo("bar"));

Task.Run vs Task.Factory.StartNew

Since it isn't practical to put code in a comment, in response to your comment in Eric's answer that it's not working for you...

I just ran the following on a SQL 2005 box (sorry, no 2000 handy) with default settings and it worked without error:

CREATE TABLE dbo.Test_Identity_Insert
(
    id  INT IDENTITY NOT NULL,
    my_string   VARCHAR(20) NOT NULL,
    CONSTRAINT PK_Test_Identity_Insert PRIMARY KEY CLUSTERED (id)
)
GO

INSERT INTO dbo.Test_Identity_Insert VALUES ('test')
GO

SELECT * FROM dbo.Test_Identity_Insert
GO

Are you perhaps sending the ID value over in your values list? I don't think that you can make it ignore the column if you actually pass a value for it. For example, if your table has 6 columns and you want to ignore the IDENTITY column you can only pass 5 values.

A web service endpoint is the URL that another program would use to communicate with your program. To see the WSDL you add ?wsdl to the web service endpoint URL.

Web services are for program-to-program interaction, while web pages are for program-to-human interaction.

So: Endpoint is: http://www.blah.com/myproject/webservice/webmethod

Therefore, WSDL is: http://www.blah.com/myproject/webservice/webmethod?wsdl

To expand further on the elements of a WSDL, I always find it helpful to compare them to code:

A WSDL has 2 portions (physical & abstract).

Physical Portion:

Definitions - variables - ex: myVar, x, y, etc.

Types - data types - ex: int, double, String, myObjectType

Operations - methods/functions - ex: myMethod(), myFunction(), etc.

Messages - method/function input parameters & return types

• ex: public myObjectType myMethod(String myVar)

Porttypes - classes (i.e. they are a container for operations) - ex: MyClass{}, etc.

Abstract Portion:

Binding - these connect to the porttypes and define the chosen protocol for communicating with this web service. - a protocol is a form of communication (so text/SMS, vs. phone vs. email, etc.).

Service - this lists the address where another program can find your web service (i.e. your endpoint).

This is just a guess, but I think your editor actually matches every single digit — 1 2 3 — but only odd matches are highlighted, to distinguish it from the case when the whole 123 string is matched.

Most regex consoles highlight contiguous matches with different colors, but due to the plugin settings, terminal limitations or for some other reason, only every other group might be highlighted in your case.

it seems you can use css and a trick (no javascript) for doing it:

1. Function imageMorph will create a new img element therefore the id is removed. Changed to

   $("#wrapper > img")

2. You should use live() function for click event if you want you rocket lanch again.

Since Android 4.2 (API 17) nested fragments become available http://developer.android.com/about/versions/android-4.2.html#NestedFragments

To place fragment inside other fragment use getChildFragmentManager()

It also available in support library!

Use Method to Serialize and Deserialize Collection object from memory. This works on Collection Data Types. This Method will Serialize collection of any type to a byte stream. Create a Seperate Class SerilizeDeserialize and add following two methods:

public class SerilizeDeserialize
{

    // Serialize collection of any type to a byte stream

    public static byte[] Serialize<T>(T obj)
    {
        using (MemoryStream memStream = new MemoryStream())
        {
            BinaryFormatter binSerializer = new BinaryFormatter();
            binSerializer.Serialize(memStream, obj);
            return memStream.ToArray();
        }
    }

    // DSerialize collection of any type to a byte stream

    public static T Deserialize<T>(byte[] serializedObj)
    {
        T obj = default(T);
        using (MemoryStream memStream = new MemoryStream(serializedObj))
        {
            BinaryFormatter binSerializer = new BinaryFormatter();
            obj = (T)binSerializer.Deserialize(memStream);
        }
        return obj;
    }

}

How To use these method in your Class:

ArrayList arrayListMem = new ArrayList() { "One", "Two", "Three", "Four", "Five", "Six", "Seven" };
Console.WriteLine("Serializing to Memory : arrayListMem");
byte[] stream = SerilizeDeserialize.Serialize(arrayListMem);

ArrayList arrayListMemDes = new ArrayList();

arrayListMemDes = SerilizeDeserialize.Deserialize<ArrayList>(stream);

Console.WriteLine("DSerializing From Memory : arrayListMemDes");
foreach (var item in arrayListMemDes)
{
    Console.WriteLine(item);
}

Use this code:

<?php
    $var = "This is Ashok's Pen.";

    mysql_real_escape_string($var);
?>

This will solve your problem, because the database can't detect the special characters of a string.

If you only want to see the keys/values from your map and like using boost, you can use the boost adaptors with the range based loops:

for (const auto& value : myMap | boost::adaptors::map_values)
{
    std::cout << value << std::endl;
}

there is an equivalent boost::adaptors::key_values

http://www.boost.org/doc/libs/1_51_0/libs/range/doc/html/range/reference/adaptors/reference/map_values.html

You can use !, but you must have the ENABLEDELAYEDEXPANSION switch set.

setlocal ENABLEDELAYEDEXPANSION
set word=table
set str="jump over the chair"
set str=%str:chair=!word!%
