I am new to python and I was already thinking I am too stupid to reproduce the simplest suggestions made here. It turns out, there's a pitfall one should know:

When a python-script is executed from IDLE, some IO-commands seem to behave completely different (as there is actually no terminal window).

Eg. msvcrt.getch is non-blocking and always returns $ff. This has already been reported long ago (see e.g. https://bugs.python.org/issue9290 ) - and it's marked as fixed, somehow the problem seems to persist in current versions of python/IDLE.

So if any of the code posted above doesn't work for you, try running the script manually, and NOT from IDLE.

In this case, I'd recommend using break labels.

http://www.java-examples.com/break-statement

This way you can specifically call it outside of the for loop.

New .NET 5 solution:

.NET 5 has introduced a a generic version for the GetValues method:

Suit[] suitValues = Enum.GetValues<Suit>();

Usage in a foreach loop:

foreach (Suit suit in Enum.GetValues<Suit>())
{

}

which is now by far the most convenient solution.

First off, you should use dataUsingEncoding: instead of going through UTF8String. You only use UTF8String when you need a C string in that encoding.

Then, for UTF-16, just pass NSUnicodeStringEncoding instead of NSUTF8StringEncoding in your dataUsingEncoding: message.

Solution option #2 offered above works for windows forms applications and not web aspx application. I got similar error in web application, I resolved this by deleting a file where I had a user control by the same name, this aspx file was actually a backup file and was not referenced anywhere in the process, but still it caused the error because the name of user control registered on the backup file was named exactly same on the aspx file which was referenced in process flow. So I deleted the backup file and built solution, build succeeded.

Hope this helps some one in similar scenario.

JavaScript validation is not secure as anybody can change what your script does in the browser. Using it for enhancing the visual experience is ok though.

var textBox = document.getElementById("myTextBox");
var textLength = textBox.value.length;
if(textLength > 5)
{
    //red
    textBox.style.backgroundColor = "#FF0000";
}
else
{
    //green
    textBox.style.backgroundColor = "#00FF00";
}

input[type="text"], textarea {

  background-color : #d1d1d1; 

}

Hope that helps :)

Edit: working example, http://jsfiddle.net/C5WxK/

1. Your UPDATE syntax is wrong
2. You probably meant to update a row not all of them so you have to use WHERE clause to target your specific row

Change

UPDATE `access_users`   
      (`contact_first_name`,`contact_surname`,`contact_email`,`telephone`) 
      VALUES (:firstname, :surname, :telephone, :email)

to

UPDATE `access_users`   
   SET `contact_first_name` = :firstname,
       `contact_surname` = :surname,
       `contact_email` = :email,
       `telephone` = :telephone 
 WHERE `user_id` = :user_id -- you probably have some sort of id 

STEP 1: To check the connected devices, run: flutter devices

STEP 2: If there are no connected devices to see the list of available emulators, run: flutter emulators

STEP 3: To run an emulator, run: flutter emulators --launch <emulator id>

STEP 4: If there is no available emulator, run: flutter emulators --create [--name xyz]

==> FOR ANDROID:

STEP 1: To check the list of emulators, run: emulator -list-avds

STEP 2: Now to launch the emulator, run: emulator -avd avd_name

==> FOR IOS:

STEP 1: open -a simulator

STEP 2: flutter run (In your app directory)

I hope this will solve your problem.

Without a bit of information about what files are in your repository (pure source code, images, executables, ...), it's a bit hard to answer the question :)

Beside this, I'll consider that you're willing to default to LF as line endings in your working directory because you're willing to make sure that text files have LF line endings in your .git repository wether you work on Windows or Linux. Indeed better safe than sorry....

However, there's a better alternative: Benefit from LF line endings in your Linux workdir, CRLF line endings in your Windows workdir AND LF line endings in your repository.

As you're partially working on Linux and Windows, make sure core.eol is set to native and core.autocrlf is set to true.

Then, replace the content of your .gitattributes file with the following

* text=auto

This will let Git handle the automagic line endings conversion for you, on commits and checkouts. Binary files won't be altered, files detected as being text files will see the line endings converted on the fly.

However, as you know the content of your repository, you may give Git a hand and help him detect text files from binary files.

Provided you work on a C based image processing project, replace the content of your .gitattributes file with the following

* text=auto
*.txt text
*.c text
*.h text
*.jpg binary

This will make sure files which extension is c, h, or txt will be stored with LF line endings in your repo and will have native line endings in the working directory. Jpeg files won't be touched. All of the others will be benefit from the same automagic filtering as seen above.

In order to get a get a deeper understanding of the inner details of all this, I'd suggest you to dive into this very good post "Mind the end of your line" from Tim Clem, a Githubber.

As a real world example, you can also peek at this commit where those changes to a .gitattributes file are demonstrated.

UPDATE to the answer considering the following comment

I actually don't want CRLF in my Windows directories, because my Linux environment is actually a VirtualBox sharing the Windows directory

Makes sense. Thanks for the clarification. In this specific context, the .gitattributes file by itself won't be enough.

Run the following commands against your repository

$ git config core.eol lf
$ git config core.autocrlf input

As your repository is shared between your Linux and Windows environment, this will update the local config file for both environment. core.eol will make sure text files bear LF line endings on checkouts. core.autocrlf will ensure potential CRLF in text files (resulting from a copy/paste operation for instance) will be converted to LF in your repository.

Optionally, you can help Git distinguish what is a text file by creating a .gitattributes file containing something similar to the following:

# Autodetect text files
* text=auto

# ...Unless the name matches the following
# overriding patterns

# Definitively text files 
*.txt text
*.c text
*.h text

# Ensure those won't be messed up with
*.jpg binary
*.data binary

If you decided to create a .gitattributes file, commit it.

Lastly, ensure git status mentions "nothing to commit (working directory clean)", then perform the following operation

$ git checkout-index --force --all

This will recreate your files in your working directory, taking into account your config changes and the .gitattributes file and replacing any potential overlooked CRLF in your text files.

Once this is done, every text file in your working directory WILL bear LF line endings and git status should still consider the workdir as clean.

Use Nullable<DateTime> if possible.

The answer depends also on your input date timezone. If your date is a local date, then you can use mktime() like katrielalex said - only I don't see why he used datetime instead of this shorter version:

>>> time.mktime(time.strptime('01/12/2011', "%d/%m/%Y"))
1322694000.0

But observe that my result is different than his, as I am probably in a different TZ (and the result is timezone-free UNIX timestamp)

Now if the input date is already in UTC, than I believe the right solution is:

>>> calendar.timegm(time.strptime('01/12/2011', '%d/%m/%Y'))
1322697600

I had a column that did not allow nulls and I was inserting a null value.

Save the commands in a .SQL file, ex: ClearTables.sql, say in your C:\temp folder.

Contents of C:\Temp\ClearTables.sql

Delete from TableA;
Delete from TableB;
Delete from TableC;
Delete from TableD;
Delete from TableE;

Then use sqlcmd to execute it as follows. Since you said the database is remote, use the following syntax (after updating for your server and database instance name).

sqlcmd -S <ComputerName>\<InstanceName> -i C:\Temp\ClearTables.sql

For example, if your remote computer name is SQLSVRBOSTON1 and Database instance name is MyDB1, then the command would be.

sqlcmd -E -S SQLSVRBOSTON1\MyDB1 -i C:\Temp\ClearTables.sql

Also note that -E specifies default authentication. If you have a user name and password to connect, use -U and -P switches.

You will execute all this by opening a CMD command window.

Using a Batch File.

If you want to save it in a batch file and double-click to run it, do it as follows.

Create, and save the ClearTables.bat like so.

echo off
sqlcmd -E -S SQLSVRBOSTON1\MyDB1 -i C:\Temp\ClearTables.sql
set /p delExit=Press the ENTER key to exit...:

Then double-click it to run it. It will execute the commands and wait until you press a key to exit, so you can see the command output.

Some supplementary info. Both flag and interrupt are suggested in the Java doc.

https://docs.oracle.com/javase/8/docs/technotes/guides/concurrency/threadPrimitiveDeprecation.html

private volatile Thread blinker;

public void stop() {
    blinker = null;
}

public void run() {
    Thread thisThread = Thread.currentThread();
    while (blinker == thisThread) {
        try {
            Thread.sleep(interval);
        } catch (InterruptedException e){
        }
        repaint();
    }
}

For a thread that waits for long periods (e.g., for input), use Thread.interrupt

public void stop() {
     Thread moribund = waiter;
      waiter = null;
      moribund.interrupt();
 }

Simple Sample

    public void showNotification (String from, String notification, Intent intent) {
        PendingIntent pendingIntent = PendingIntent.getActivity(
                context,
                Notification_ID,
                intent,
                PendingIntent.FLAG_UPDATE_CURRENT
        );


        String NOTIFICATION_CHANNEL_ID = "my_channel_id_01";
        NotificationManager notificationManager = (NotificationManager) context.getSystemService(Context.NOTIFICATION_SERVICE);


        if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.O) {
            NotificationChannel notificationChannel = new NotificationChannel(NOTIFICATION_CHANNEL_ID, "My Notifications", NotificationManager.IMPORTANCE_DEFAULT);

            // Configure the notification channel.
            notificationChannel.setDescription("Channel description");
            notificationChannel.enableLights(true);
            notificationChannel.setLightColor(Color.RED);
            notificationChannel.setVibrationPattern(new long[]{0, 1000, 500, 1000});
            notificationChannel.enableVibration(true);
            notificationManager.createNotificationChannel(notificationChannel);
        }


        NotificationCompat.Builder builder = new NotificationCompat.Builder(context, NOTIFICATION_CHANNEL_ID);
        Notification mNotification = builder
                .setContentTitle(from)
                .setContentText(notification)

//                .setTicker("Hearty365")
//                .setContentInfo("Info")
                //     .setPriority(Notification.PRIORITY_MAX)

                .setContentIntent(pendingIntent)

                .setAutoCancel(true)
//                .setDefaults(Notification.DEFAULT_ALL)
//                .setWhen(System.currentTimeMillis())
                .setSmallIcon(R.mipmap.ic_launcher)
                .setLargeIcon(BitmapFactory.decodeResource(context.getResources(), R.mipmap.ic_launcher))
                .build();

        notificationManager.notify(/*notification id*/Notification_ID, mNotification);

    }

There is no implicit style that you have to choose, it involves writing a bit of code using the QuartzCore framework:

//first, you
#import <QuartzCore/QuartzCore.h>

//.....

//Here I add a UITextView in code, it will work if it's added in IB too
UITextView *textView = [[UITextView alloc] initWithFrame:CGRectMake(50, 220, 200, 100)];

//To make the border look very close to a UITextField
[textView.layer setBorderColor:[[[UIColor grayColor] colorWithAlphaComponent:0.5] CGColor]];
[textView.layer setBorderWidth:2.0];

//The rounded corner part, where you specify your view's corner radius:
textView.layer.cornerRadius = 5;
textView.clipsToBounds = YES;

It only works on OS 3.0 and above, but I guess now it's the de facto platform anyway.

In the case of having this message in live tests, but not in unit tests, it's because selected assemblies are copied on the fly to $(SolutionDir)\.vs\$(SolutionName)\lut\0\0\x64\Debug\. But sometime few assemblies can be not selected, eg., VC++ dlls in case of interop c++/c# projects.

Post-build xcopy won't correct the problem, because the copied file will be erased by the live test engine.

The only workaround to date (28 dec 2018), is to avoid Live tests, and do everything in unit tests with the attribute [TestCategory("SkipWhenLiveUnitTesting")] applied to the test class or the test method.

Other answers assume you want to know it from a popup or background script.

In case you want to know the current URL from a content script, the standard JS way applies:

window.location.toString()

You can use properties of window.location to access individual parts of the URL, such as host, protocol or path.

The path is a list of directories where the command prompt will look for executable files, if it can't find it in the current directory. The OP seems to be trying to add the actual executable, when it just needs to specify the path where the executable is.

A connection timeout occurs only upon starting the TCP connection. This usually happens if the remote machine does not answer. This means that the server has been shut down, you used the wrong IP/DNS name, wrong port or the network connection to the server is down.

A socket timeout is dedicated to monitor the continuous incoming data flow. If the data flow is interrupted for the specified timeout the connection is regarded as stalled/broken. Of course this only works with connections where data is received all the time.

By setting socket timeout to 1 this would require that every millisecond new data is received (assuming that you read the data block wise and the block is large enough)!

If only the incoming stream stalls for more than a millisecond you are running into a timeout.

We need to do the following changes/fixes in our earlier onActivityResult()'s gallery picker code to run seamlessly on Android 4.4 (KitKat) and on all other earlier versions as well.

Uri selectedImgFileUri = data.getData();

if (selectedImgFileUri == null ) {

    // The user has not selected any photo
}

try {

   InputStream input = mActivity.getContentResolver().openInputStream(selectedImgFileUri);
   mSelectedPhotoBmp = BitmapFactory.decodeStream(input);
}
catch (Throwable tr) {

    // Show message to try again
}

From performance standpoint - Yes string(PK) will slow down the performance when compared to performance achieved using an integer(PK), where PK ---> Primary Key.

From requirement standpoint - Although this is not a part of your question still I would like to mention. When we are handling huge data across different tables we generally look for the probable set of keys that can be set for a particular table. This is primarily because there are many tables and mostly each or some table would be related to the other through some relation ( a concept of Foreign Key ). Therefore we really cannot always choose an integer as a Primary Key, rather we go for a combination of 3, 4 or 5 attributes as the primary key for that tables. And those keys can be used as a foreign key when we would relate the records with some other table. This makes it useful to relate the records across different tables when required.

Therefore for Optimal Usage - We always make a combination of 1 or 2 integers with 1 or 2 string attributes, but again only if it is required.

You can set the state of the checkbox based on the value:

$('#your-checkbox').prop('checked', value == 1);

Assign primary key in hibernate

Make sure that the attribute is primary key and Auto Incrementable in the database. Then map it into the data class with the annotation with @GeneratedValue annotation using IDENTITY.

@Entity
@Table(name = "client")
data class Client(
        @Id @GeneratedValue(strategy = GenerationType.IDENTITY) @Column(name = "id") private val id: Int? = null

You really should have multiple input, e.g. one for firstname, middle names, lastname and another one for age. If you want to have some fun though you could try:

>>> input_given="join smith 25"
>>> chars="".join([i for i in input_given if not i.isdigit()])
>>> age=input_given.translate(None,chars)
>>> age
'25'
>>> name=input_given.replace(age,"").strip()
>>> name
'join smith'

This would of course fail if there is multiple numbers in the input. a quick check would be:

assert(age in input_given)

and also:

assert(len(name)<len(input_given))

This error is caused by failer of the ng serve serve to automatically pick up a newly added file. To fix this, simply restart your server.

Though closing the reopening the text editor or IDE solves this problem, many people do not want to go through all of the stress of reopening the project. To Fix this without closing the text editor...

In terminal where the server is running,

• Press ctrl+C to stop the server then,
• Start the server again: ng serve

That should work.

1) To redirect to the login page / from the login page, don't use the Redirect() methods. Use FormsAuthentication.RedirectToLoginPage() and FormsAuthentication.RedirectFromLoginPage() !

2) You should just use RedirectToAction("action", "controller") in regular scenarios.. You want to redirect in side the Initialize method? Why? I don't see why would you ever want to do this, and in most cases you should review your approach imo.. If you want to do this for authentication this is DEFINITELY the wrong way (with very little chances foe an exception) Use the [Authorize] attribute on your controller or method instead :)

UPD: if you have some security checks in the Initialise method, and the user doesn't have access to this method, you can do a couple of things: a)

Response.StatusCode = 403;
Response.End();

This will send the user back to the login page. If you want to send him to a custom location, you can do something like this (cautios: pseudocode)

Response.Redirect(Url.Action("action", "controller"));

No need to specify the full url. This should be enough. If you completely insist on the full url:

Response.Redirect(new Uri(Request.Url, Url.Action("action", "controller")).ToString());

Here's a demo: http://jsfiddle.net/thirtydot/JJytE/1170/

CSS:

.circleBase {
    border-radius: 50%;

    height: 100px;
    background: yellow;
    border: 3px solid red;
}
.type2 {

.type3 {

HTML:

<div class="circleBase type1"></div>

<div class="circleBase type2"></div><div class="circleBase type2"></div>

<div class="circleBase type3"></div>

To make this work in IE8 and older, you must download and use CSS3 PIE. My demo above won't work in IE8, but that's only because jsFiddle doesn't host PIE.htc.

My demo looks like this:

Why not just have a Year property, which is perfectly fine?

Interfaces don't contain fields because fields represent a specific implementation of data representation, and exposing them would break encapsulation. Thus having an interface with a field would effectively be coding to an implementation instead of an interface, which is a curious paradox for an interface to have!

For instance, part of your Year specification might require that it be invalid for ICar implementers to allow assignment to a Year which is later than the current year + 1 or before 1900. There's no way to say that if you had exposed Year fields -- far better to use properties instead to do the work here.

When you put the username and password in front of the host, this data is not sent that way to the server. It is instead transformed to a request header depending on the authentication schema used. Most of the time this is going to be Basic Auth which I describe below. A similar (but significantly less often used) authentication scheme is Digest Auth which nowadays provides comparable security features.

With Basic Auth, the HTTP request from the question will look something like this:

GET / HTTP/1.1
Host: example.com
Authorization: Basic Zm9vOnBhc3N3b3Jk

The hash like string you see there is created by the browser like this: base64_encode(username + ":" + password).

To outsiders of the HTTPS transfer, this information is hidden (as everything else on the HTTP level). You should take care of logging on the client and all intermediate servers though. The username will normally be shown in server logs, but the password won't. This is not guaranteed though. When you call that URL on the client with e.g. curl, the username and password will be clearly visible on the process list and might turn up in the bash history file.

When you send passwords in a GET request as e.g. http://example.com/login.php?username=me&password=secure the username and password will always turn up in server logs of your webserver, application server, caches, ... unless you specifically configure your servers to not log it. This only applies to servers being able to read the unencrypted http data, like your application server or any middleboxes such as loadbalancers, CDNs, proxies, etc. though.

Basic auth is standardized and implemented by browsers by showing this little username/password popup you might have seen already. When you put the username/password into an HTML form sent via GET or POST, you have to implement all the login/logout logic yourself (which might be an advantage and allows you to more control over the login/logout flow for the added "cost" of having to implement this securely again). But you should never transfer usernames and passwords by GET parameters. If you have to, use POST instead. The prevents the logging of this data by default.

When implementing an authentication mechanism with a user/password entry form and a subsequent cookie-based session as it is commonly used today, you have to make sure that the password is either transported with POST requests or one of the standardized authentication schemes above only.

Concluding I could say, that transfering data that way over HTTPS is likely safe, as long as you take care that the password does not turn up in unexpected places. But that advice applies to every transfer of any password in any way.

I had the same issue but in this case microsoft-ace-oledb-12-0-provider was already installed on my machine and working fine for other application developed.

The difference between those application and the one with I had the problem was the Old Applications were running on "Local IIS" whereas the one with error was on "IIS Express(running from Visual Studio"). So what I did was-

1. Right Click on Project Name.
2. Go to Properties
3. Go to Web Tab on the right.
4. Under Servers select Local IIS and click on Create Virtual Directory button.
5. Run the application again and it worked.

With Stream API you can do something like this:

List<String> aWithoutB = a.stream()
    .filter(element -> !b.contains(element))
    .collect(Collectors.toList());

List<String> bWithoutA = b.stream()
    .filter(element -> !a.contains(element))
    .collect(Collectors.toList());

This creates a "jump" due to variable heights... to solve that, try something like this: Select the tallest image of a list

Updating others' answers with the new syntax:

<li *ngFor="let obj of myArray">{{obj | json}}</li>

Notepad++ provides 2 types of features:

• Auto-completion that read the open file and provide suggestion of words and/or functions within the file
• Suggestion with the arguments of functions (specific to the language)

Based on what you write, it seems what you want is auto-completion on function only + suggestion on arguments.

To do that, you just need to change a setting.

1. Go to Settings > Preferences... > Auto-completion
2. Check Enable Auto-completion on each input
3. Select Function completion and not Word completion
4. Check Function parameter hint on input (if you have this option)

On version 6.5.5 of Notepad++, I have this setting

Some documentation about auto-completion is available in Notepad++ Wiki.

you can simply use :

error_log("your message");

By default, the message will be send to the php system logger.

Try this:

var request = WebRequest.Create("http://www.gravatar.com/avatar/6810d91caff032b202c50701dd3af745?d=identicon&r=PG");

using (var response = request.GetResponse())
using (var stream = response.GetResponseStream())
{
    pictureBox1.Image = Bitmap.FromStream(stream);
}

I had input type text field in a table row field. I am targeting it with code

.admin_table input[type=text]:focus
{
    background-color: #FEE5AC;
}

To avoid leaving the file open, it is best to pass a block to File.open. This way, the file will be closed after the block executes.

contents = File.open('path-to-file.tar.gz', 'rb') { |f| f.read }

This can be done by creating a .pgpass file in the home directory of the (Linux) User. .pgpass file format:

<databaseip>:<port>:<databasename>:<dbusername>:<password>

You can also use wild card * in place of details.

Say I wanted to run tmp.sql without prompting for a password.

With the following code you can in *.sh file

echo "192.168.1.1:*:*:postgres:postgrespwd" > $HOME/.pgpass
echo "` chmod 0600 $HOME/.pgpass `"

echo " ` psql -h 192.168.1.1 -p 5432  -U postgres  postgres  -f tmp.sql `        

var express = require('express')

app = module.exports = express();
var secureServer = require('http').createServer(app);
secureServer.listen(3001);

var aws = require('aws-sdk')
var multer = require('multer')
var multerS3 = require('multer-s3')

    aws.config.update({
    secretAccessKey: "XXXXXXXXXXXXXXXXXXXXXXXXXXXXX",
    accessKeyId: "XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX",
    region: 'us-east-1'
    });
    s3 = new aws.S3();

   var upload = multer({
   storage: multerS3({
    s3: s3,
    dirname: "uploads",
    bucket: "Your bucket name",
    key: function (req, file, cb) {
        console.log(file);
        cb(null, "uploads/profile_images/u_" + Date.now() + ".jpg"); //use  
     Date.now() for unique file keys
    }
  })
   });

 app.post('/upload', upload.single('photos'), function(req, res, next) {

 console.log('Successfully uploaded ', req.file)

 res.send('Successfully uploaded ' + req.file.length + ' files!')

})

For us, the key difference is in overall perf...

Have a look at Logger.IsDebugEnabled in NLog versus Log4Net, from our tests, NLog has less overhead and that's what we are after (low-latency stuff).

var FD = new System.Windows.Forms.OpenFileDialog();
if (FD.ShowDialog() == System.Windows.Forms.DialogResult.OK) {
    string fileToOpen = FD.FileName;

    System.IO.FileInfo File = new System.IO.FileInfo(FD.FileName);

    //OR

    System.IO.StreamReader reader = new System.IO.StreamReader(fileToOpen);
    //etc
}

Also, if your table has no ID column, or sorting by id doesn't return you the last row, you can always use sqlite schema native 'rowid' field.

SELECT column 
FROM table 
WHERE rowid = (SELECT MAX(rowid) FROM table);

you can make your own regular expression for javascript validation

    /^            : Start
    (?=.{8,})        : Length
    (?=.*[a-zA-Z])   : Letters
    (?=.*\d)         : Digits
    (?=.*[!#$%&? "]) : Special characters
    $/              : End



        (/^
        (?=.*\d)                //should contain at least one digit
        (?=.*[a-z])             //should contain at least one lower case
        (?=.*[A-Z])             //should contain at least one upper case
        [a-zA-Z0-9]{8,}         //should contain at least 8 from the mentioned characters

        $/)

Example:-   /^(?=.*\d)(?=.*[a-zA-Z])[a-zA-Z0-9]{7,}$/

You can technically use colons and periods in id/name attributes, but I would strongly suggest avoiding both.

In CSS (and several JavaScript libraries like jQuery), both the period and the colon have special meaning and you will run into problems if you're not careful. Periods are class selectors and colons are pseudo-selectors (eg., ":hover" for an element when the mouse is over it).

If you give an element the id "my.cool:thing", your CSS selector will look like this:

#my.cool:thing { ... /* some rules */ ... }

Which is really saying, "the element with an id of 'my', a class of 'cool' and the 'thing' pseudo-selector" in CSS-speak.

Stick to A-Z of any case, numbers, underscores and hyphens. And as said above, make sure your ids are unique.

That should be your first concern.

You can use:

    select FK_Items,Sum(PoiQuantity) Quantity  from PurchaseOrderItems POI
    left join PurchaseOrder PO ON po.ID_PurchaseOrder=poi.FK_PurchaseOrder
    group by FK_Items,DATEPART(MONTH, TransDate)

I use this code in the SQLiteOpenHelper in one of my applications to import a database file.

EDIT: I pasted my FileUtils.copyFile() method into the question.

SQLiteOpenHelper

public static String DB_FILEPATH = "/data/data/{package_name}/databases/database.db";

/**
 * Copies the database file at the specified location over the current
 * internal application database.

public boolean importDatabase(String dbPath) throws IOException {

    // Close the SQLiteOpenHelper so it will commit the created empty
    // database to internal storage.
    close();
    File newDb = new File(dbPath);
    File oldDb = new File(DB_FILEPATH);
    if (newDb.exists()) {
        FileUtils.copyFile(new FileInputStream(newDb), new FileOutputStream(oldDb));
        // Access the copied database so SQLiteHelper will cache it and mark
        // it as created.
        getWritableDatabase().close();
        return true;
    }
    return false;
}

FileUtils

public class FileUtils {
    /**

    public static void copyFile(FileInputStream fromFile, FileOutputStream toFile) throws IOException {
        FileChannel fromChannel = null;
        FileChannel toChannel = null;
        try {
            fromChannel = fromFile.getChannel();
            toChannel = toFile.getChannel();
            fromChannel.transferTo(0, fromChannel.size(), toChannel);
        } finally {
            try {
                if (fromChannel != null) {
                    fromChannel.close();
                }
            } finally {
                if (toChannel != null) {
                    toChannel.close();
                }
            }
        }
    }
}

Don't forget to delete the old database file if necessary.

As a good example may be worth it to navigate to this project and see how to handle exiting processes grammatically or in this snippet from VM found in here

                ConsoleOutputStream = new ObservableCollection<string>();

                var startInfo = new ProcessStartInfo(FilePath)
                {
                    WorkingDirectory = RootFolderPath,
                    Arguments = StartingArguments,
                    RedirectStandardOutput = true,
                    UseShellExecute = false,
                    CreateNoWindow = true
                };
                ConsoleProcess = new Process {StartInfo = startInfo};

                ConsoleProcess.EnableRaisingEvents = true;

                ConsoleProcess.OutputDataReceived += (sender, args) =>
                {
                    App.Current.Dispatcher.Invoke((System.Action) delegate
                    {
                        ConsoleOutputStream.Insert(0, args.Data);
                        //ConsoleOutputStream.Add(args.Data);
                    });
                };
                ConsoleProcess.Exited += (sender, args) =>
                {
                    InProgress = false;
                };

                ConsoleProcess.Start();
                ConsoleProcess.BeginOutputReadLine();
        }
    }

    private void RegisterProcessWatcher()
    {
        startWatch = new ManagementEventWatcher(
            new WqlEventQuery($"SELECT * FROM Win32_ProcessStartTrace where ProcessName = '{FileName}'"));
        startWatch.EventArrived += new EventArrivedEventHandler(startProcessWatch_EventArrived);

        stopWatch = new ManagementEventWatcher(
            new WqlEventQuery($"SELECT * FROM Win32_ProcessStopTrace where ProcessName = '{FileName}'"));
        stopWatch.EventArrived += new EventArrivedEventHandler(stopProcessWatch_EventArrived);
    }

    private void stopProcessWatch_EventArrived(object sender, EventArrivedEventArgs e)
    {
        InProgress = false;
    }

    private void startProcessWatch_EventArrived(object sender, EventArrivedEventArgs e)
    {
        InProgress = true;
    }

Remove the z-index value.

I would also recommend this approach.

HTML:

<header class="main-header" role="banner">
  <img src="mybannerimage.gif" alt="Banner Image"/>
</header>

CSS:

.main-header {
  text-align: center;
}

This will center your image with out stretching it out. You can adjust the padding as needed to give it some space around your image. Since this is at the top of your page you don't need to force it there with position absolute unless you want your other elements to go underneath it. In that case you'd probably want position:fixed; anyway.

all of above answers would help you but you have to add three ports in the firewall of PC on which SQL Server is installed.

1. Add new TCP Local port in Windows firewall at port no. 1434

2. Add new program for SQL Server and select sql server.exe Path: C:\ProgramFiles\Microsoft SQL Server\MSSQL10.MSSQLSERVER\MSSQL\Binn\sqlservr.exe

3. Add new program for SQL Browser and select sqlbrowser.exe Path: C:\ProgramFiles\Microsoft SQL Server\90\Shared\sqlbrowser.exe

You can't call a non-static method without first creating an instance of its parent class.

So from the static method, you would have to instantiate a new object...

Vehicle myCar = new Vehicle();

... and then call the non-static method.

myCar.Drive();

Try this:

var src = DateTime.Now;
var hm = new DateTime(src.Year, src.Month, src.Day, src.Hour, src.Minute, 0);

None, because having an ORM takes too much control away with small benefits. The time savings gained are easily blown away when you have to debug abnormalities resulting from the use of the ORM. Furthermore, ORMs discourage developers from learning SQL and how relational databases work and using this for their benefit.

Open the Servers view -> double click tomcat -> drop down the Timeouts section you can increase the startup time for each particular server. like 45 to 450

Ok, here's a basic join query that gets the correct records:

   int[] selectedRolesArr = GetSelectedRoles();
    if( selectedRolesArr != null && selectedRolesArr.Length > 0 ) 
    {

    //this join version requires the use of distinct to prevent muliple records
        //being returned for users with more than one company role.
    IQueryable retVal = (from u in context.Users
                        join c in context.CompanyRolesToUsers
                          on u.Id equals c.UserId
                        where u.LastName.Contains( "fra" ) &&
                            selectedRolesArr.Contains( c.CompanyRoleId )
                        select  u).Distinct();
}

But here's the code that most easily integrates with the algorithm that we already had in place:

int[] selectedRolesArr = GetSelectedRoles(); 
if ( useAnd ) 
       { 
          predicateAnd = predicateAnd.And( u => (from c in context.CompanyRolesToUsers 
                       where selectedRolesArr.Contains(c.CompanyRoleId) 
                       select c.UserId).Contains(u.Id)); 
        } 
        else 
        { 
           predicateOr = predicateOr.Or( u => (from c in context.CompanyRolesToUsers 
                          where selectedRolesArr.Contains(c.CompanyRoleId) 
                         select c.UserId).Contains(u.Id) ); 
        } 

which is thanks to a poster at the LINQtoSQL forum

Simplest form that worked for me.

import traceback

While researching this topic, I found this proof-of-concept code (via a comment at http://jlebar.com/2010/2/1/Replacing_Bash.html) that lets you "write shell-like pipelines in Python using a terse syntax, and leveraging existing system tools where they make sense":

for line in sh("cat /tmp/junk2") | cut(d=',',f=1) | 'sort' | uniq:
    sys.stdout.write(line)

use following code

function numericFilter(txb) {
   txb.value = txb.value.replace(/[^\0-9]/ig, "");
}

call it in on key up

<input type="text" onKeyUp="numericFilter(this);" />

Well, since neither of the given replies helped me, I had to look more, and found solution in this article.

And the answer in a nutshell is the following:

Connecting to MySQL using MySQL Workbench

Connection Method: Standard TCP/IP over SSH
SSH Hostname: <Local VM IP Address (set in PuPHPet)>
SSH Username: vagrant (the default username)
SSH Password: vagrant (the default password)
MySQL Hostname: 127.0.0.1
MySQL Server Port: 3306
Username: root
Password: <MySQL Root Password (set in PuPHPet)>

Using given approach I was able to connect to mysql database in vagrant from host Ubuntu machine using MySQL Workbench and also using Valentina Studio.

WITH uniq AS (
        SELECT DISTINCT posts.id as post_id
        FROM posts
        JOIN votes ON votes.post_id = posts.id
        -- GROUP BY not needed anymore
        -- GROUP BY posts.id
        )
SELECT COUNT(*)
FROM uniq;

Cheap trick:

Convert.ToString((object)stringVar) == “”

This works because Convert.ToString(object) returns an empty string if object is null. Convert.ToString(string) returns null if string is null.

(Or, if you're using .NET 2.0 you could always using String.IsNullOrEmpty.)

I found this useful to read from a specific column and row:

FileStream stream = File.Open(@"C:\Users\Desktop\ExcelDataReader.xlsx", FileMode.Open, FileAccess.Read);
IExcelDataReader excelReader = ExcelReaderFactory.CreateOpenXmlReader(stream);
DataSet result = excelReader.AsDataSet();
excelReader.IsFirstRowAsColumnNames = true;         
DataTable dt = result.Tables[0];
string text = dt.Rows[1][0].ToString();

it's quite handy with {data.table} and {stringr}

library(data.table)
library(stringr)

x[, lapply(.SD, function(xx) {str_replace_na(xx, 0)})]

FYI

You can get access to the options array of a selected object by going document.getElementById("cars").options where 'cars' is the select object.

Once you have that you can call option[i].setAttribute('selected', 'selected'); to select an option.

I agree with every one else that you are better off doing this server side though.

Of-course this is an old thread but to make it complete.

From SQL 2008 you can use DATE datatype so you can simply do:

SELECT CONVERT(DATE,GETDATE())

ng-bind-html-unsafe only renders the content as HTML. It doesn't bind Angular scope to the resulted DOM. You have to use $compile service for that purpose. I created this plunker to demonstrate how to use $compile to create a directive rendering dynamic HTML entered by users and binding to the controller's scope. The source is posted below.

demo.html

<!DOCTYPE html>
<html ng-app="app">

  <head>
    <script data-require="[email protected]" data-semver="1.0.7" src="https://ajax.googleapis.com/ajax/libs/angularjs/1.0.7/angular.js"></script>
    <script src="script.js"></script>
  </head>

  <body>
    <h1>Compile dynamic HTML</h1>
    <div ng-controller="MyController">
      <textarea ng-model="html"></textarea>
      <div dynamic="html"></div>
    </div>
  </body>

</html>

script.js

var app = angular.module('app', []);

app.directive('dynamic', function ($compile) {
  return {
    restrict: 'A',
    replace: true,
    link: function (scope, ele, attrs) {
      scope.$watch(attrs.dynamic, function(html) {
        ele.html(html);
        $compile(ele.contents())(scope);
      });
    }
  };
});

function MyController($scope) {
  $scope.click = function(arg) {
    alert('Clicked ' + arg);
  }
  $scope.html = '<a ng-click="click(1)" href="#">Click me</a>';
}

LIMIT is usually applied as the last operation, so the result will first be sorted and then limited to 20. In fact, sorting will stop as soon as first 20 sorted results are found.

I know that this is an old question, but as I was googling it was the first link in a results. So here is the jsp solution:

<form action="some.jsp">
  <select name="item">
    <option value="1">1</option>
    <option value="2">2</option>
    <option value="3">3</option>
  </select>
  <input type="submit" value="Submit">
</form>

in some.jsp

request.getParameter("item");

this line will return the selected option (from the example it is: 1, 2 or 3)

Another simple way ( might not be the best practice) but works like charm. Build the HTML tag of your element(hyperLink or Button) dynamically with javascript, and can pass multiple parameters as well.

// variable to hold the HTML Tags 
var ProductButtonsHTML  ="";

//Run your loop
for (var i = 0; i < ProductsJson.length; i++){
// Build the <input> Tag with the required parameters for Onclick call. Use double quotes.

ProductButtonsHTML += " <input type='button' value='" + ProductsJson[i].DisplayName + "'  
onclick = \"BuildCartById('" + ProductsJson[i].SKU+ "'," + ProductsJson[i].Id + ")\"></input> ";

}

// Add the Tags to the Div's innerHTML.
document.getElementById("divProductsMenuStrip").innerHTML = ProductButtonsHTML;

If you use HashSet instead of List for listofGenres you can do:

var genres = new HashSet<Genre>() { "action", "comedy" };   
var movies = _db.Movies.Where(p => genres.Overlaps(p.Genres));

Folks, here's why you should use 1px instead of 1dp or 1dip: if you specify 1dp or 1dip, Android will scale that down. On a 120dpi device, that becomes something like 0.75px translated, which rounds to 0. On some devices, that translates to 2-3 pixels, and it usually looks ugly or sloppy

For dividers, 1px is the correct height if you want a 1 pixel divider and is one of the exceptions for the "everything should be dip" rule. It'll be 1 pixel on all screens. Plus, 1px usually looks better on hdpi and above screens

"It's not 2012 anymore" edit: you may have to switch over to dp/dip starting at a certain screen density

In HTML:

  <form id="my_form"><input id="my_field" type="date" /></form>

In JavaScript

   // test and transform if needed_x000D_
    if($('#my_field').attr('type') === 'text'){_x000D_
        $('#my_field').attr('type', 'text').attr('placeholder','aaaa-mm-dd');  _x000D_
    };_x000D_
_x000D_
    // check_x000D_
    if($('#my_form')[0].elements[0].value.search(/(19[0-9][0-9]|20[0-1][0-5])[- \-.](0[1-9]|1[012])[- \-.](0[1-9]|[12][0-9]|3[01])$/i) === 0){_x000D_
        $('#my_field').removeClass('bad');_x000D_
    } else {_x000D_
        $('#my_field').addClass('bad');_x000D_
    };

It looks like the phoneGap plugin will allow you to get the device's uid.

http://docs.phonegap.com/en/3.0.0/cordova_device_device.md.html#device.uuid

Update: This is dependent on running native code. We used this solution writing javascript that was being compiled to native code for a native phone application we were creating.

One of the reasons of your problem could be the password policy you are using.

And if there is no such policy of yours then check your settings for the password properties in the DEFAULT profile with the following query:

SELECT resource_name, limit
FROM dba_profiles 
WHERE profile = 'DEFAULT'
AND resource_type = 'PASSWORD';

And If required, you just need to change the PASSWORD_LIFE_TIME to unlimited with the following query:

ALTER PROFILE DEFAULT LIMIT PASSWORD_LIFE_TIME UNLIMITED;

And this Link might be helpful for your problem.

For SQL Server

select *
from YourTable
where DateCol between getdate() and dateadd(d, 90, getdate())

Adding both "arn:aws:s3:::your_bucket_name" and "arn:aws:s3:::your_bucket_name/*" to policy congiguration fixed the issue for me.

This is PKCS#1 format of a private key. Try this code. It doesn't use Bouncy Castle or other third-party crypto providers. Just java.security and sun.security for DER sequece parsing.

Any .apk file from market or unsigned

1. If you apk is downloaded from market and hence signed Install Astro File Manager from market. Open Astro > Tools > Application Manager/Backup and select the application to backup on to the SD card . Mount phone as USB drive and access 'backupsapps' folder to find the apk of target app (lets call it app.apk) . Copy it to your local drive same is the case of unsigned .apk.

2. Download Dex2Jar zip from this link: SourceForge

3. Unzip the downloaded zip file.

4. Open command prompt & write the following command on reaching to directory where dex2jar exe is there and also copy the apk in same directory.

   dex2jar targetapp.apk file(./dex2jar app.apk on terminal)

5. http://jd.benow.ca/ download decompiler from this link.

6. Open ‘targetapp.apk.dex2jar.jar’ with jd-gui File > Save All Sources to sava the class files in jar to java files.

To check MySQL version of MAMP , use the following command in Terminal:

/Applications/MAMP/Library/bin/mysql --version

Assume you have started MAMP .

Example output:

./mysql  Ver 14.14 Distrib 5.1.44, for apple-darwin8.11.1 (i386) using  EditLine wrapper

UPDATE: Moreover, if you want to find where does mysql installed in system, use the following command:

type -a mysql

type -a is an equivalent of tclsh built-in command where in OS X bash shell. If MySQL is found, it will show :

mysql is /usr/bin/mysql

If not found, it will show:

-bash: type: mysql: not found

By default , MySQL is not installed in Mac OS X.

Sidenote: For XAMPP, the command should be:

/Applications/XAMPP/xamppfiles/bin/mysql --version

Your issue is with attempting to change your month by adding 1. 1 in date serials in Excel is equal to 1 day. Try changing your month by using the following:

NewDate = Format(DateAdd("m",1,StartDate),"dd/mm/yyyy")

Unfortunately there is not cross browser JavaScript support for trim().

If you aren't using jQuery (which has a .trim() method) you can use the following methods to add trim support to strings:

String.prototype.trim = function() {
    return this.replace(/^\s+|\s+$/g,"");
}
String.prototype.ltrim = function() {
    return this.replace(/^\s+/,"");
}
String.prototype.rtrim = function() {
    return this.replace(/\s+$/,"");
}

TL;DR: Specify key file in group variable file, since 'tag_Name_server1' is a group.

Note: I'm assuming you're using the EC2 external inventory script. If you're using some other dynamic inventory approach, you might need to tweak this solution.

This is an issue I've been struggling with, on and off, for months, and I've finally found a solution, thanks to Brian Coca's suggestion here. The trick is to use Ansible's group variable mechanisms to automatically pass along the correct SSH key file for the machine you're working with.

The EC2 inventory script automatically sets up various groups that you can use to refer to hosts. You're using this in your playbook: in the first play, you're telling Ansible to apply 'role1' to the entire 'tag_Name_server1' group. We want to direct Ansible to use a specific SSH key for any host in the 'tag_Name_server1' group, which is where group variable files come in.

Assuming that your playbook is located in the 'my-playbooks' directory, create files for each group under the 'group_vars' directory:

my-playbooks
|-- test.yml
+-- group_vars
     |-- tag_Name_server1.yml
     +-- tag_Name_server2.yml

Now, any time you refer to these groups in a playbook, Ansible will check the appropriate files, and load any variables you've defined there.

Within each group var file, we can specify the key file to use for connecting to hosts in the group:

# tag_Name_server1.yml
# --------------------
# 
# Variables for EC2 instances named "server1"
---
ansible_ssh_private_key_file: /path/to/ssh/key/server1.pem

Now, when you run your playbook, it should automatically pick up the right keys!

Using environment vars for portability

I often run playbooks on many different servers (local, remote build server, etc.), so I like to parameterize things. Rather than using a fixed path, I have an environment variable called SSH_KEYDIR that points to the directory where the SSH keys are stored.

In this case, my group vars files look like this, instead:

# tag_Name_server1.yml
# --------------------
# 
# Variables for EC2 instances named "server1"
---
ansible_ssh_private_key_file: "{{ lookup('env','SSH_KEYDIR') }}/server1.pem"

Further Improvements

There's probably a bunch of neat ways this could be improved. For one thing, you still need to manually specify which key to use for each group. Since the EC2 inventory script includes details about the keypair used for each server, there's probably a way to get the key name directly from the script itself. In that case, you could supply the directory the keys are located in (as above), and have it choose the correct keys based on the inventory data.

Call it like this:

foo(*ob);

Note that there is no casting going on here, as suggested in your question title. All we have done is de-referenced the pointer to the object which we then pass to the function.

Test execution result different from JUnit run and from maven install seems to be symptom for several problems.

Disabling thread reusing test execution did also get rid of the symptom in our case, but the impression that the code was not thread-safe was still strong.

In our case the difference was due to the presence of a bean that modified the test behaviour. Running just the JUnit test would result fine, but running the project install target would result in a failed test case. Since it was the test case under development, it was immediately suspicious.

It resulted that another test case was instantiating a bean through Spring that would survive until the execution of the new test case. The bean presence was modifying the behaviour of some classes and producing the failed result.

The solution in our case was getting rid of the bean, which was not needed in the first place (yet another prize from the copy+paste gun).

I suggest everybody with this symptom to investigate what the root cause is. Disabling thread reuse in test execution might only hide it.

cache:true only works with GET and HEAD request.

You could roll your own solution as you said with something along these lines :

var localCache = {
    data: {},
    remove: function (url) {
        delete localCache.data[url];
    },
    exist: function (url) {
        return localCache.data.hasOwnProperty(url) && localCache.data[url] !== null;
    },
    get: function (url) {
        console.log('Getting in cache for url' + url);
        return localCache.data[url];
    },
    set: function (url, cachedData, callback) {
        localCache.remove(url);
        localCache.data[url] = cachedData;
        if ($.isFunction(callback)) callback(cachedData);
    }
};

$(function () {
    var url = '/echo/jsonp/';
    $('#ajaxButton').click(function (e) {
        $.ajax({
            url: url,
            data: {
                test: 'value'
            },
            cache: true,
            beforeSend: function () {
                if (localCache.exist(url)) {
                    doSomething(localCache.get(url));
                    return false;
                }
                return true;
            },
            complete: function (jqXHR, textStatus) {
                localCache.set(url, jqXHR, doSomething);
            }
        });
    });
});

function doSomething(data) {
    console.log(data);
}

Working fiddle here

EDIT: as this post becomes popular, here is an even better answer for those who want to manage timeout cache and you also don't have to bother with all the mess in the $.ajax() as I use $.ajaxPrefilter(). Now just setting {cache: true} is enough to handle the cache correctly :

var localCache = {
    /**
     * timeout for cache in millis
     * @type {number}
     */
    timeout: 30000,
    /** 
     * @type {{_: number, data: {}}}
     **/
    data: {},
    remove: function (url) {
        delete localCache.data[url];
    },
    exist: function (url) {
        return !!localCache.data[url] && ((new Date().getTime() - localCache.data[url]._) < localCache.timeout);
    },
    get: function (url) {
        console.log('Getting in cache for url' + url);
        return localCache.data[url].data;
    },
    set: function (url, cachedData, callback) {
        localCache.remove(url);
        localCache.data[url] = {
            _: new Date().getTime(),
            data: cachedData
        };
        if ($.isFunction(callback)) callback(cachedData);
    }
};

$.ajaxPrefilter(function (options, originalOptions, jqXHR) {
    if (options.cache) {
        var complete = originalOptions.complete || $.noop,
            url = originalOptions.url;
        //remove jQuery cache as we have our own localCache
        options.cache = false;
        options.beforeSend = function () {
            if (localCache.exist(url)) {
                complete(localCache.get(url));
                return false;
            }
            return true;
        };
        options.complete = function (data, textStatus) {
            localCache.set(url, data, complete);
        };
    }
});

$(function () {
    var url = '/echo/jsonp/';
    $('#ajaxButton').click(function (e) {
        $.ajax({
            url: url,
            data: {
                test: 'value'
            },
            cache: true,
            complete: doSomething
        });
    });
});

function doSomething(data) {
    console.log(data);
}

And the fiddle here CAREFUL, not working with $.Deferred

Here is a working but flawed implementation working with deferred:

var localCache = {
    /**
     * timeout for cache in millis
     * @type {number}
     */
    timeout: 30000,
    /** 
     * @type {{_: number, data: {}}}
     **/
    data: {},
    remove: function (url) {
        delete localCache.data[url];
    },
    exist: function (url) {
        return !!localCache.data[url] && ((new Date().getTime() - localCache.data[url]._) < localCache.timeout);
    },
    get: function (url) {
        console.log('Getting in cache for url' + url);
        return localCache.data[url].data;
    },
    set: function (url, cachedData, callback) {
        localCache.remove(url);
        localCache.data[url] = {
            _: new Date().getTime(),
            data: cachedData
        };
        if ($.isFunction(callback)) callback(cachedData);
    }
};

$.ajaxPrefilter(function (options, originalOptions, jqXHR) {
    if (options.cache) {
        //Here is our identifier for the cache. Maybe have a better, safer ID (it depends on the object string representation here) ?
        // on $.ajax call we could also set an ID in originalOptions
        var id = originalOptions.url+ JSON.stringify(originalOptions.data);
        options.cache = false;
        options.beforeSend = function () {
            if (!localCache.exist(id)) {
                jqXHR.promise().done(function (data, textStatus) {
                    localCache.set(id, data);
                });
            }
            return true;
        };

    }
});

$.ajaxTransport("+*", function (options, originalOptions, jqXHR, headers, completeCallback) {

    //same here, careful because options.url has already been through jQuery processing
    var id = originalOptions.url+ JSON.stringify(originalOptions.data);

    options.cache = false;

    if (localCache.exist(id)) {
        return {
            send: function (headers, completeCallback) {
                completeCallback(200, "OK", localCache.get(id));
            },
            abort: function () {
                /* abort code, nothing needed here I guess... */
            }
        };
    }
});

$(function () {
    var url = '/echo/jsonp/';
    $('#ajaxButton').click(function (e) {
        $.ajax({
            url: url,
            data: {

Fiddle HERE Some issues, our cache ID is dependent of the json2 lib JSON object representation.

Use Console view (F12) or FireBug to view some logs generated by the cache.

Here is a simple way using the date function:

select *
from hockey_stats
where date(game_date) between date('2012-11-03') and date('2012-11-05')
order by game_date desc

The typedef would be

typedef char type24[3];

However, this is probably a very bad idea, because the resulting type is an array type, but users of it won't see that it's an array type. If used as a function argument, it will be passed by reference, not by value, and the sizeof for it will then be wrong.

A better solution would be

typedef struct type24 { char x[3]; } type24;

You probably also want to be using unsigned char instead of char, since the latter has implementation-defined signedness.

Seems I don't have enough rep to post a comment, so another answer will have to do.

When you unlink a node using removeChild() or by setting the innerHTML property on the parent, you also need to make sure that there is nothing else referencing it otherwise it won't actually be destroyed and will lead to a memory leak. There are lots of ways in which you could have taken a reference to the node before calling removeChild() and you have to make sure those references that have not gone out of scope are explicitly removed.

Doug Crockford writes here that event handlers are known a cause of circular references in IE and suggests removing them explicitly as follows before calling removeChild()

function purge(d) {
    var a = d.attributes, i, l, n;
    if (a) {
        for (i = a.length - 1; i >= 0; i -= 1) {
            n = a[i].name;
            if (typeof d[n] === 'function') {
                d[n] = null;
            }
        }
    }
    a = d.childNodes;
    if (a) {
        l = a.length;
        for (i = 0; i < l; i += 1) {
            purge(d.childNodes[i]);
        }
    }
}

And even if you take a lot of precautions you can still get memory leaks in IE as described by Jens-Ingo Farley here.

And finally, don't fall into the trap of thinking that Javascript delete is the answer. It seems to be suggested by many, but won't do the job. Here is a great reference on understanding delete by Kangax.

@techedemic is correct but is missing '.' to mention the current directory, and this command go throught all subdirectories.

find . -name '*.gz' -exec gunzip '{}' \;

Check the size of the input file, then output any number which is too large to be represented by a file that size. This may seem like a cheap trick, but it's a creative solution to an interview problem, it neatly sidesteps the memory issue, and it's technically O(n).

void maxNum(ulong filesize)
{
    ulong bitcount = filesize * 8; //number of bits in file

    for (ulong i = 0; i < bitcount; i++)
    {
        Console.Write(9);
    }
}

Should print 10 ^bitcount - 1, which will always be greater than 2 ^bitcount. Technically, the number you have to beat is 2 ^bitcount - (4 * 10⁹ - 1), since you know there are (4 billion - 1) other integers in the file, and even with perfect compression they'll take up at least one bit each.

To align horizontally it's pretty straight forward:

    <style type="text/css"> 
body  {
    margin: 0; 
    padding: 0;
    text-align: center;
}
.bodyclass #container { 
    width: ???px; /*SET your width here*/
    margin: 0 auto;
    text-align: left;
} 
</style>
<body class="bodyclass ">
<div id="container">type your content here</div>
</body>

and for vertical align, it's a bit tricky: here's the source

    <!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01//EN">
<html>
<head>
  <title>Universal vertical center with CSS</title>
  <style>
    .greenBorder {border: 1px solid green;} /* just borders to see it */
  </style>
</head>

<body>
  <div class="greenBorder" style="display: table; height: 400px; #position: relative; overflow: hidden;">
    <div style=" #position: absolute; #top: 50%;display: table-cell; vertical-align: middle;">
      <div class="greenBorder" style=" #position: relative; #top: -50%">
        any text<br>
        any height<br>
        any content, for example generated from DB<br>
        everything is vertically centered
      </div>
    </div>
  </div>
</body>
</html>

do not forget to do it with parse html. like:

$.ajax({
    url: url, 
    cache: false,
    success: function(response) {
        var parsed = $.parseHTML(response);
        result = $(parsed).find("#result");
    }
});

has to work :)

If you wanted to remove the href, change the cursor and also prevent clicking on it, this should work:

$("a").attr('href', '').css({'cursor': 'pointer', 'pointer-events' : 'none'});

In JUnit 4.13 you can do:

import static org.junit.Assert.assertEquals;
import static org.junit.Assert.assertThrows;

...

@Test
void exceptionTesting() {
  IllegalArgumentException exception = assertThrows(
    IllegalArgumentException.class, 
    () -> { throw new IllegalArgumentException("a message"); }
  );

  assertEquals("a message", exception.getMessage());
}

This also works in JUnit 5 but with different imports:

import static org.junit.jupiter.api.Assertions.assertEquals;
import static org.junit.jupiter.api.Assertions.assertThrows;

According to docker docs,

Both CMD and ENTRYPOINT instructions define what command gets executed when running a container. There are few rules that describe their co-operation.

1. Dockerfile should specify at least one of CMD or ENTRYPOINT commands.
2. ENTRYPOINT should be defined when using the container as an executable.
3. CMD should be used as a way of defining default arguments for an ENTRYPOINT command or for executing an ad-hoc command in a container.
4. CMD will be overridden when running the container with alternative arguments.

The tables below shows what command is executed for different ENTRYPOINT / CMD combinations:

-- No ENTRYPOINT

+----------------------------------------------------------+
¦ No CMD                     ¦ error, not allowed          ¦

There is no notion of method overloading in Python. But you can achieve a similar effect by specifying optional and keyword arguments

I've just used this pattern, which I prefer:

read name || name='(nobody)'

In some cases you might end up having chain of observables, wherein your observable would return another observable. 'flatmap' kind of unwraps the second observable which is buried in the first one and let you directly access the data second observable is spitting out while subscribing.

The return value of receive will be -1 if connection is lost else it will be size of buffer.

void ReceiveStream(void *threadid)
{
    while(true)
    {
        while(ch==0)
        {
            char buffer[1024];
            int newData;
            newData = recv(thisSocket, buffer, sizeof(buffer), 0);
            if(newData>=0)
            {
                std::cout << buffer << std::endl;
            }
            else
            {
                std::cout << "Client disconnected" << std::endl;
                if (thisSocket)
                {
                    #ifdef WIN32
                        closesocket(thisSocket);
                        WSACleanup();
                    #endif
                    #ifdef LINUX
                        close(thisSocket);
                    #endif
                }
                break;
            }
        }
        ch = 1;
        StartSocket();
    }
}

This is works for me on Ubuntu 18.04 with Postman v7.1.1 which is released on 20 May, 2019.

Download the latest version of Postman.

• For Linux 32-bit
• For Linux 64-bit

Most probably your downloaded file should be in Downloads folder.

# Postman-linux-x64-7.1.1.tar.gz is my downloaded file

cd /home/YOUR_USERNAME/Downloads/
tar -xzf Postman-linux-x64-7.1.1.tar.gz Postman/
sudo mv Postman /usr/share/postman
sudo ln -s /usr/share/postman/Postman /usr/bin/postman

If you get an error like this,

/usr/share/postman/Postman: error while loading shared libraries: libgconf-2.so.4: cannot open shared object file: No such file or directory

please install libgconf-2-4.

sudo apt install libgconf-2-4

Just type postman in your terminal and hit enter to run latest version of Postman. Now we have to create an Unity desktop file for your launcher. For create postman.desktop file run the below command.

sudo nano ~/.local/share/applications/postman.desktop

Then paste below lines into the postman.desktop file.

[Desktop Entry]
Encoding=UTF-8
Name=Postman
Exec=postman
Icon=/usr/share/postman/app/resources/app/assets/icon.png
Terminal=false
Type=Application
Categories=Development;

Now you can see the "Postman" icon in your Unity launcher. If you miss any point please go through this video or comment below.

For those searching for a solution not based on jQuery, this is a plain JavaScript version of the solution provided by Thomas M:

window.addEventListener("storage", message_receive);

function message_broadcast(message) {
    localStorage.setItem('message',JSON.stringify(message));
}

function message_receive(ev) {
    if (ev.key == 'message') {
        var message=JSON.parse(ev.newValue);
    }
}

How are you generating your data?

See how the output shows that your data is of 'object' type? the groupby operations specifically check whether each column is a numeric dtype first.

In [31]: data
Out[31]: 
<class 'pandas.core.frame.DataFrame'>
DatetimeIndex: 2557 entries, 2004-01-01 00:00:00 to 2010-12-31 00:00:00
Freq: <1 DateOffset>
Columns: 360 entries, -89.75 to 89.75
dtypes: object(360)

look ?

Did you initialize an empty DataFrame first and then filled it? If so that's probably why it changed with the new version as before 0.9 empty DataFrames were initialized to float type but now they are of object type. If so you can change the initialization to DataFrame(dtype=float).

You can also call frame.astype(float)

Yes, it can be done.
It is based on the new html5 "download" attribute of anchor tags.
The flow should be something like this :

1. load the image
2. draw the image into a canvas with the crop boundaries specified
3. get the image data from the canvas and make it a href attribute for an anchor tag in the dom
4. add the download attribute (download="desired-file-name") to that a element That's it. all the user has to do is click your "download link" and the image will be downloaded to his pc.

I'll come back with a demo when I get the chance.

Update
Here's the live demo as I promised. It takes the jsfiddle logo and crops 5px of each margin.
The code looks like this :

var img = new Image();
img.onload = function(){
    var cropMarginWidth = 5,
        canvas = $('<canvas/>')
                    .attr({
                         width: img.width - 2 * cropMarginWidth,
                         height: img.height - 2 * cropMarginWidth
                     })
                    .hide()
                    .appendTo('body'),
        ctx = canvas.get(0).getContext('2d'),
        a = $('<a download="cropped-image" title="click to download the image" />'),
        cropCoords = {
            topLeft : {
                x : cropMarginWidth,
                y : cropMarginWidth 
            },
            bottomRight :{
                x : img.width - cropMarginWidth,
                y : img.height - cropMarginWidth
            }
        };

    ctx.drawImage(img, cropCoords.topLeft.x, cropCoords.topLeft.y, cropCoords.bottomRight.x, cropCoords.bottomRight.y, 0, 0, img.width, img.height);
    var base64ImageData = canvas.get(0).toDataURL();


    a
        .attr('href', base64ImageData)
        .text('cropped image')
        .appendTo('body');

    a
        .clone()
        .attr('href', img.src)
        .text('original image')
        .attr('download','original-image')
        .appendTo('body');

    canvas.remove();
}
img.src = 'some-image-src';

Update II
Forgot to mention : of course there is a downside :(.
Because of the same-origin policy that is applied to images too, if you want to access an image's data (through the canvas method toDataUrl).
So you would still need a server-side proxy that would serve your image as if it were hosted on your domain.

Update III Although I can't provide a live demo for this (for security reasons), here is a php sample code that solves the same-origin policy :

file proxy.php :

$imgData = getimagesize($_GET['img']);
header("Content-type: " . $imgData['mime']);
echo file_get_contents($_GET['img']);  

This way, instead of loading the external image direct from it's origin :

img.src = 'http://some-domain.com/imagefile.png';

You can load it through your proxy :

img.src = 'proxy.php?img=' + encodeURIComponent('http://some-domain.com/imagefile.png');  

And here's a sample php code for saving the image data (base64) into an actual image :

file save-image.php :

$data = preg_replace('/data:image\/(png|jpg|jpeg|gif|bmp);base64/','',$_POST['data']);
$data = base64_decode($data);
$img = imagecreatefromstring($data);

$path = 'path-to-saved-images/';
// generate random name
$name  = substr(md5(time()),10);
$ext = 'png';
$imageName = $path.$name.'.'.$ext;

// write the image to disk
imagepng($img,  $imageName);
imagedestroy($img);
// return the image path
echo $imageName;

All you have to do then is post the image data to this file and it will save the image to disc and return you the existing image filename.

Of course all this might feel a bit complicated, but I wanted to show you that what you're trying to achieve is possible.

Using jQuery throttle / debounce

jQuery debounce is a nice one for problems like this. jsFidlle

$(window).scroll($.debounce( 250, true, function(){
    $('#scrollMsg').html('SCROLLING!');
}));
$(window).scroll($.debounce( 250, function(){
    $('#scrollMsg').html('DONE!');
}));

The second parameter is the "at_begin" flag. Here I've shown how to execute code both at "scroll start" and "scroll finish".

Using Lodash

As suggested by Barry P, jsFiddle, underscore or lodash also have a debounce, each with slightly different apis.

$(window).scroll(_.debounce(function(){
    $('#scrollMsg').html('SCROLLING!');
}, 150, { 'leading': true, 'trailing': false }));

$(window).scroll(_.debounce(function(){
    $('#scrollMsg').html('STOPPED!');
}, 150));

All the methods above do not handle deep cloning of objects where it is nested to n levels. I did not check its performance over others but it is short and simple.

The first example below shows object cloning using Object.assign which clones just till first level.

var person = {_x000D_
    name:'saksham',_x000D_
    age:22,_x000D_
    skills: {_x000D_
        lang:'javascript',_x000D_
        experience:5_x000D_
    }_x000D_
}_x000D_
_x000D_
newPerson = Object.assign({},person);_x000D_
newPerson.skills.lang = 'angular';_x000D_
console.log(newPerson.skills.lang); //logs Angular

Using the below approach deep clones object

var person = {_x000D_
    name:'saksham',_x000D_
    age:22,_x000D_
    skills: {_x000D_
        lang:'javascript',_x000D_
        experience:5_x000D_
    }_x000D_
}_x000D_
_x000D_
anotherNewPerson = JSON.parse(JSON.stringify(person));_x000D_
anotherNewPerson.skills.lang = 'angular';_x000D_
console.log(person.skills.lang); //logs javascript

You may use event handler serverclick as below

//cmdAction is the id of HTML button as below

<body>
    <form id="form1" runat="server">
        <button type="submit" id="cmdAction" text="Button1" runat="server">
            Button1
        </button>
    </form>
</body>

//cs code

public partial class _Default : System.Web.UI.Page
    {
        protected void Page_Load(object sender, EventArgs e)
        {
                cmdAction.ServerClick += new EventHandler(submit_click);  
        }

        protected void submit_click(object sender, EventArgs e)
        {
            Response.Write("HTML Server Button Control");
        }
    }

There is no button type cancel https://www.w3schools.com/jsref/prop_pushbutton_type.asp

To achieve cancel functionality I used DOM history

<button type="button" class="btn btn-primary" onclick="window.history.back();">Cancel</button>

For more details : https://www.w3schools.com/jsref/met_his_back.asp

Set the text of the button by setting the innerHTML

var b = document.createElement('button');
b.setAttribute('content', 'test content');
b.setAttribute('class', 'btn');
b.innerHTML = 'test value';

var wrapper = document.getElementById('divWrapper');
wrapper.appendChild(b);

It is time inefficient to compare each number, needlessly leading to a linear complexity. Having said that, this approach avoids any inequality checks:

import itertools

m, n = 5, 10
for i in itertools.chain(range(m), range(m + 1, n)):
    print(i)  # skips m = 5

As an aside, you woudn't want to use (*range(m), *range(m + 1, n)) even though it works because it will expand the iterables into a tuple and this is memory inefficient.

Using QPainter and QImage to paint on a window-widget (QMainWindow) (just another method)

class MainWindow : public QMainWindow
{    
    public:
        MainWindow();
    protected:
        void paintEvent(QPaintEvent* event) override;

    protected:
        QImage image = QImage("/path/to/image.jpg");
};

// for convenience resize window to image size
MainWindow::MainWindow()
{
    setMinimumSize(image.size());
}

void MainWindow::paintEvent(QPaintEvent* event)
{
    QPainter painter(this);
    QRect rect = event->rect();
    painter.drawImage(rect, image, rect);
}


int main(int argc, char** argv)
{
    QApplication a(argc, argv);

    MainWindow mainWindow;
    mainWindow.show();
    return a.exec();
}

@mmrobins @AaronM @ErikZ @JamesMishra provided variants that all have an problem in common: they ask git to produce a mixture of info not intended for script consumption, including line contents from repository on the same line, then match the mess with a regexp.

This is a problem when some lines aren't valid UTF-8 text, and also when some lines happen to match the regexp (this happened here).

Here's a modified line that doesn't have these problems. It requests git to output data cleanly on separate lines, which makes it easy to filter what we want robustly:

git ls-files -z | xargs -0n1 git blame -w --line-porcelain | grep -a "^author " | sort -f | uniq -c | sort -n

You can grep for other strings, like author-mail, committer, etc.

Perhaps first do export LC_ALL=C (assuming bash) to force byte-level processing (this also happens to speed up grep tremendously from the UTF-8-based locales).

Just change the class container to container-fullwidth like this :

<div class="container-fullwidth">

It is important to know not only the types but the mapping of these types to the database types, too:

Source added - Agile Web Development with Rails 4

There are some online services for obfuscate php to hide the code from others. This is one Right Coder's Free Obfuscator Online

@Glavic is right. "Nothing is bulletproof". You can encode your source code and hide from bigger programmers, not from experts.

ASP.Net automatically generates unique client IDs for server-side controls.

Change it to

 $('#<%= lblVessel.ClientID %>')

In ASP.Net 4.0, you could also set the ClientIDMode property to Static instead.

For me the simple solution works to set cookies in HttpRequestMessage object.

protected async Task<HttpResponseMessage> SendRequest(HttpRequestMessage requestMessage, CancellationToken cancellationToken = default(CancellationToken))
{
    requestMessage.Headers.Add("Cookie", $"<Cookie Name 1>=<Cookie Value 1>;<Cookie Name 2>=<Cookie Value 2>");

    return await _httpClient.SendAsync(requestMessage, cancellationToken).ConfigureAwait(false);
}

you can use this script

# git mv a folder and sub folders in windows 

function Move-GitFolder {
    param (
        $target,
        $destination
    )
    
    Get-ChildItem $target -recurse |
    Where-Object { ! $_.PSIsContainer } |
    ForEach-Object { 
        $fullTargetFolder = [System.IO.Path]::GetFullPath((Join-Path (Get-Location) $target))
        $fullDestinationFolder = [System.IO.Path]::GetFullPath((Join-Path (Get-Location) $destination))
        $fileDestination = $_.Directory.FullName.Replace($fullTargetFolder.TrimEnd('\'), $fullDestinationFolder.TrimEnd('\'))

        New-Item -ItemType Directory -Force -Path $fileDestination | Out-Null

        $filePath = Join-Path $fileDestination $_.Name

        git mv $_.FullName $filePath
        
    }
}

Usage

Move-GitFolder <Target folder> <Destination folder>

the advantage of this solution over other solutions is that it move folders and files recursively in a folder and even create the folder structure if it doesn't exist

I want to improve Fabio's answer and create a function which adds custom key to the URL string without reloading the page.

function insertUrlParam(key, value) {
    if (history.pushState) {
        let searchParams = new URLSearchParams(window.location.search);
        searchParams.set(key, value);
        let newurl = window.location.protocol + "//" + window.location.host + window.location.pathname + '?' + searchParams.toString();
        window.history.pushState({path: newurl}, '', newurl);
    }
}

You can declare the field as a first-class attribute of your form and just set choices dynamically:

class WaypointForm(forms.Form):
    waypoints = forms.ChoiceField(choices=[])

    def __init__(self, user, *args, **kwargs):
        super().__init__(*args, **kwargs)
        waypoint_choices = [(o.id, str(o)) for o in Waypoint.objects.filter(user=user)]
        self.fields['waypoints'].choices = waypoint_choices

You can also use a ModelChoiceField and set the queryset on init in a similar manner.

What I use:

<span style="border-bottom: 1px solid black"> Enter text here </span>

if my_list is the list that you want to store your objects in it and my_object is your object wanted to be stored, use this structure:

my_list.append(my_object)

I really liked Al P's answer but wanted uniqueness enforced cheaply so I took it one step further - use a directory. There are some obvious limitations (directory file limits, invalid file names) but it should work for most cases.

hinit() {
    rm -rf /tmp/hashmap.$1
    mkdir -p /tmp/hashmap.$1
}

hput() {
    printf "$3" > /tmp/hashmap.$1/$2
}

hget() {
    cat /tmp/hashmap.$1/$2
}

hkeys() {
    ls -1 /tmp/hashmap.$1
}

hdestroy() {
    rm -rf /tmp/hashmap.$1
}

hinit ids

for (( i = 0; i < 10000; i++ )); do
    hput ids "key$i" "value$i"
done

for (( i = 0; i < 10000; i++ )); do
    printf '%s\n' $(hget ids "key$i") > /dev/null
done

hdestroy ids

It also performs a tad bit better in my tests.

$ time bash hash.sh 
real    0m46.500s
user    0m16.767s
sys     0m51.473s

$ time bash dirhash.sh 
real    0m35.875s
user    0m8.002s
sys     0m24.666s

Just thought I'd pitch in. Cheers!

Edit: Adding hdestroy()

Try below code segment, I've tried it myself before :

#your-div {
    background: url("your-image-link") no-repeat;
    background-size: cover;
    background-clip: border-box;
}

Invalid App Store Icon. The App Store Icon in the asset catalog in 'YourApp.app' can't be transparent nor contain an alpha channel.

Solved in Catalina

1. copy to desktop
2. open image in PREVIEW APP.
3. File -> Duplicate Close the first opened preview
4. after try to close the second duplicated image, then it will prompt to save there you will available to untick AlPHA

look into my screenshot

If you're just comparing for equality, you can just do this:

if not dict1 == dict2:
    match = False

Otherwise, the only major problem I see is that you're going to get a KeyError if there is a key in dict1 that is not in dict2, so you may want to do something like this:

for key in dict1:
    if not key in dict2 or dict1[key] != dict2[key]:
        match = False

You could compress this into a comprehension to just get the list of keys that don't match too:

mismatch_keys = [key for key in x if not key in y or x[key] != y[key]]
match = not bool(mismatch_keys) #If the list is not empty, they don't match 
for key in mismatch_keys:
    print key
    print '%s -> %s' % (dict1[key],dict2[key])

The only other optimization I can think of might be to use "len(dict)" to figure out which dict has fewer entries and loop through that one first to have the shortest loop possible.

<script type="text/javascript">
function showDiv(toggle){
document.getElementById(toggle).style.display = 'block';
}

<input type="button" name="answer" onclick="showDiv('toggle')">Show</input>

<div id="toggle" style="display:none">Hello</div>

Not the best way but If you are using mac or linux even in windows you can set alias for different registries.

Disabling SQL Net Banners saved us.

The answer given by @ray above works perfectly, but make sure you are using the right path to open up the file. If you right click on your icon and click properties, you should see where the actual path is, just copy past that and it should work.

Main issue is that you first need to set the location of your x and y ticks. Also, it helps to use the more object-oriented interface to matplotlib. Namely, interact with the axes object directly.

import matplotlib.pyplot as plt
import numpy as np
column_labels = list('ABCD')
row_labels = list('WXYZ')
data = np.random.rand(4,4)
fig, ax = plt.subplots()
heatmap = ax.pcolor(data)

# put the major ticks at the middle of each cell, notice "reverse" use of dimension
ax.set_yticks(np.arange(data.shape[0])+0.5, minor=False)
ax.set_xticks(np.arange(data.shape[1])+0.5, minor=False)


ax.set_xticklabels(row_labels, minor=False)
ax.set_yticklabels(column_labels, minor=False)
plt.show()

Hope that helps.

It's not clear whether you're asking this because you are new to programming, but if that's the case then you should probably read this article on loops and indeed read some basic materials on programming.

If you already know about control structures and you want the R-specific implementation details then there are dozens of tutorials around, such as this one. The other answer uses replicate and colMeans, which is idiomatic when writing in R and probably blazing fast as well, which is important if you want 10,000 iterations.

However, one more general and (for beginners) straightforward way to approach problems of this sort would be to use a for loop.

> for (ii in 1:5) { + print(ii) + } [1] 1 [1] 2 [1] 3 [1] 4 [1] 5 > 

So in your case, if you just wanted to print the mean of your Tandem object 5 times:

for (ii in 1:5) {     Tandem <- sample(OUT, size = 815, replace = TRUE, prob = NULL)     TandemMean <- mean(Tandem)     print(TandemMean) } 

As mentioned above, replicate is a more natural way to deal with this specific problem using R. Either way, if you want to store the results - which is surely the case - you'll need to start thinking about data structures like vectors and lists. Once you store something you'll need to be able to access it to use it in future, so a little knowledge is vital.

I am using lambda with Zappa; I am sending data with POST in json format:

My code for basic_lambda_pure.py is:

import time
import requests
import json
def my_handler(event, context):
    print("Received event: " + json.dumps(event, indent=2))
    print("Log stream name:", context.log_stream_name)
    print("Log group name:",  context.log_group_name)
    print("Request ID:", context.aws_request_id)
    print("Mem. limits(MB):", context.memory_limit_in_mb)
    # Code will execute quickly, so we add a 1 second intentional delay so you can see that in time remaining value.
    print("Time remaining (MS):", context.get_remaining_time_in_millis())

    if event["httpMethod"] == "GET":
        hub_mode = event["queryStringParameters"]["hub.mode"]
        hub_challenge = event["queryStringParameters"]["hub.challenge"]
        hub_verify_token = event["queryStringParameters"]["hub.verify_token"]
        return {'statusCode': '200', 'body': hub_challenge, 'headers': 'Content-Type': 'application/json'}}

    if event["httpMethod"] == "post":
        token = "xxxx"
    params = {
        "access_token": token
    }
    headers = {
        "Content-Type": "application/json"
    }
        _data = {"recipient": {"id": 1459299024159359}}
        _data.update({"message": {"text": "text"}})
        data = json.dumps(_data)
        r = requests.post("https://graph.facebook.com/v2.9/me/messages",params=params, headers=headers, data=data, timeout=2)
        return {'statusCode': '200', 'body': "ok", 'headers': {'Content-Type': 'application/json'}}

I got the next json response:

my data was on body key, but is code64 encoded, How can I know this? I saw the key isBase64Encoded

I copy the value for body key and decode with This tool and "eureka", I get the values.

I hope this help you. :)

Could use JSON2HTML to transform it to nicely formatted HTML list .. may be a little more powerful than you really need though

http://json2html.com

Basically, Serializable is a marker interface that implies that a class is safe for serialization and the JVM determines how it is serialized. Externalizable contains 2 methods, readExternal and writeExternal. Externalizable allows the implementer to decide how an object is serialized, where as Serializable serializes objects the default way.

The closest I have been able to find is called 3taps. 3taps was sued by Craigslist with the result that "access to public data on a public website can be selectively censored by blacklisting certain viewers (i.e. competitors)", and thus states that "3taps will therefore access the very same data exclusively from public sources that retain open and equal access rights to public data".

Use the basename command. Its manpage is here: http://unixhelp.ed.ac.uk/CGI/man-cgi?basename

Just to add to the other examples, there are inner(nested) classes that appear with the $ sign. For example:

public class Test {

    private static void privateMethod() {
        throw new RuntimeException();
    }

    public static void main(String[] args) throws Exception {
        Runnable runnable = new Runnable() {
            @Override public void run() {
                privateMethod();
            }
        };
        runnable.run();
    }
}

Will result in this stack trace:

Exception in thread "main" java.lang.RuntimeException
        at Test.privateMethod(Test.java:4)
        at Test.access$000(Test.java:1)
        at Test$1.run(Test.java:10)
        at Test.main(Test.java:13)

I use these defines:

/** Use to init the clock */
#define TIMER_INIT \
    LARGE_INTEGER frequency; \
    LARGE_INTEGER t1,t2; \
    double elapsedTime; \
    QueryPerformanceFrequency(&frequency);


/** Use to start the performance timer */
#define TIMER_START QueryPerformanceCounter(&t1);

/** Use to stop the performance timer and output the result to the standard stream. Less verbose than \c TIMER_STOP_VERBOSE */
#define TIMER_STOP \
    QueryPerformanceCounter(&t2); \
    elapsedTime=(float)(t2.QuadPart-t1.QuadPart)/frequency.QuadPart; \
    std::wcout<<elapsedTime<<L" sec"<<endl;

Usage (brackets to prevent redefines):

TIMER_INIT

{
   TIMER_START
   Sleep(1000);
   TIMER_STOP
}

{
   TIMER_START
   Sleep(1234);
   TIMER_STOP
}

Output from usage example:

1.00003 sec
1.23407 sec

To specify a Dockerfile when build, you can use:

docker build -t ubuntu-test:latest - < /path/to/your/Dockerfile

But it'll fail if there's ADD or COPY command that depends on relative path. There're many ways to specify a context for docker build, you can refer to docs of docker build for more info.

Here is an example of decoding a generic map using both switch and reflection, so if you don't match the type, use reflection to figure it out and then add the type in next time.

var data map[string]interface {}

...

for k, v := range data {
    fmt.Printf("pair:%s\t%s\n", k, v)   

    switch t := v.(type) {
    case int:
        fmt.Printf("Integer: %v\n", t)
    case float64:
        fmt.Printf("Float64: %v\n", t)
    case string:
        fmt.Printf("String: %v\n", t)
    case bool:
        fmt.Printf("Bool: %v\n", t)
    case []interface {}:
        for i,n := range t {
            fmt.Printf("Item: %v= %v\n", i, n)
        }
    default:
        var r = reflect.TypeOf(t)
        fmt.Printf("Other:%v\n", r)             
    }
}

I figured it out myself. I need

select extract(day from sysdate - to_date('2009-10-01', 'yyyy-mm-dd')) from dual

Use INSERT ... ON DUPLICATE KEY UPDATE

QUERY:

INSERT INTO table (id, name, age) VALUES(1, "A", 19) ON DUPLICATE KEY UPDATE    
name="A", age=19

If you want to know when use is looking at the fragment you should use

yourFragment.isResumed()

instead of

yourFragment.isVisible()

First of all isVisible() already checks for isAdded() so no need for calling both. Second, non-of these two means that user is actually seeing your fragment. Only isResumed() makes sure that your fragment is in front of the user and user can interact with it if thats whats you are looking for.

 CGRect buttonFrame = CGRectMake( x-pos, y-pos, width, height );   //
 CGRectMake(10,5,10,10) 

 UIButton *button = [[UIButton alloc] initWithFrame: buttonFrame];

 button setTitle: @"My Button" forState: UIControlStateNormal];

 [button addTarget:self action:@selector(btnClicked:) 
 forControlEvents:UIControlEventTouchUpInside];

 [button setTitleColor: [UIColor BlueVolor] forState:
 UIControlStateNormal];

 [view addSubview:button];




 -(void)btnClicked {
    // your code }

Import mplot3d whole to use "projection = '3d'".

Insert the command below in top of your script. It should run fine.

from mpl_toolkits import mplot3d

Yes, and no. There are min and max attributes in HTML 5, but

The max attribute will not work for dates and time in Internet Explorer 10+ or Firefox, since IE 10+ and Firefox does not support these input types.

EDIT: Firefox now does support it

So if you are confused by the documentation of that attributes, yet it doesn't work, that's why.
See the W3 page for the versions.

I find it easiest to use Javascript, s the other answers say, since you can just use a pre-made module. Also, many Javascript date picker libraries have a min/max setting and have that nice calendar look.

One way can be to circularly store the values in the buffer array. and calculate average this way.

int j = (int) (counter % size);
buffer[j] = mostrecentvalue;
avg = (avg * size - buffer[j - 1 == -1 ? size - 1 : j - 1] + buffer[j]) / size;

counter++;

// buffer[j - 1 == -1 ? size - 1 : j - 1] is the oldest value stored

The whole thing runs in a loop where most recent value is dynamic.

My solution was pretty simple. I noticed that docker was running linux containers instead of windows containers. What i did is switch to windows containers by right clicking on the docker icon in the system tray and choosing Switch to Windows Containers.

Well it has a simple and easy solution. You can make your video easily to fit for any device and screen size. Here is the HTML and CSS code:

.yt-container {_x000D_

 padding-top:30px;_x000D_
 height:0;_x000D_

_x000D_
.yt-container iframe, .yt-container object, .yt-container embed {_x000D_

A repo may seem corrupted if you mix different git versions.

Local repositories touched by new git versions aren't backwards-compatible with old git versions. New git repos look corrupted to old git versions (in my case git 2.28 broke repo for git 2.11).

Updating old git version may solve the problem.

If you want to wait for jobs to finish, use wait. This will make the shell wait until all background jobs complete. However, if any of your jobs daemonize themselves, they are no longer children of the shell and wait will have no effect (as far as the shell is concerned, the child is already done. Indeed, when a process daemonizes itself, it does so by terminating and spawning a new process that inherits its role).

#!/bin/sh
{ sleep 5; echo waking up after 5 seconds; } &
{ sleep 1; echo waking up after 1 second; } &
wait
echo all jobs are done!

if(wheel > 0) {
    this.scale *= 1.1; 
    this.offsetX -= (mouseX - this.offsetX) * (1.1 - 1);
    this.offsetY -= (mouseY - this.offsetY) * (1.1 - 1);
}
else {
    this.scale *= 1/1.1; 
    this.offsetX -= (mouseX - this.offsetX) * (1/1.1 - 1);
    this.offsetY -= (mouseY - this.offsetY) * (1/1.1 - 1);
}

SFTP is not FTP over SSH, it's a different protocol and being similar to SCP, it's offers more capabilities.

First, make sure that the source page and the target page are both served through the file URI scheme. You can't force an http page to open a file page (but it works the other way around).

Next, your script that calls window.open() should be invoked by a user-initiated event, such as clicks, keypresses and the like. Simply calling window.open() won't work.

You can test this right here in this question page. Run these in Chrome's JavaScript console:

// Does nothing
window.open('http://google.com');

// Click anywhere within this page and the new window opens
$(document.body).unbind('click').click(function() { window.open('http://google.com'); });

// This will open a new window, but it would be blank
$(document.body).unbind('click').click(function() { window.open('file:///path/to/a/local/html/file.html'); });

You can also test if this works with a local file. Here's a sample HTML file that simply loads jQuery:

<html>
    <head>
        <script type="text/javascript" src="https://ajax.googleapis.com/ajax/libs/jquery/1.5.0/jquery.min.js"></script>
    </head>
    <body>
        <h5>Feel the presha</h5>
        <h3>Come play my game, I'll test ya</h3>
        <h1>Psycho- somatic- addict- insane!</h1>
    </body>
</html>

Then open Chrome's JavaScript console and run the statements above. The 3rd one will now work.

You can use ComboBox, then point your mouse to the upper arrow facing right, it will unfold a box called ComboBox Tasks and in there you can go ahead and edit your items or fill in the items / strings one per line. This should be the easiest.

Since this isn't closed, i would like to submit a new entry for anyone looking to have something working properly for them... using an amalgamation of what i found here, as well as using DirectoryServices to debug the code itself and find the proper code to use, here's what i found that works for me in every situation... note that my solution extends DirectoryInfo object... :

Yes, but its generally a very bad idea to force another thread to interrupt on a random line of code. You would only do this if you intend to shutdown the process.

What you can do is to use Thread.interrupt() for a task after a certain amount of time. However, unless the code checks for this it won't work. An ExecutorService can make this easier with Future.cancel(true)

Its much better for the code to time itself and stop when it needs to.

In Java, List is an interface. That is, it cannot be instantiated directly.

Instead you can use ArrayList which is an implementation of that interface that uses an array as its backing store (hence the name).

Since ArrayList is a kind of List, you can easily upcast it:

List<T> mylist = new ArrayList<T>();

This is in contrast with .NET, where, since version 2.0, List<T> is the default implementation of the IList<T> interface.

If you are converting DataFrame to JSON, NaN will give error so best solution is in this use case is to replace NaN with None.
Here is how:

df1 = df.where((pd.notnull(df)), None)

THIS IS BROKEN, SEE EDIT

<script type="text/javascript">
$("a.more").fancybox({
                    'titleShow'     : false,
                    'transitionIn'  : 'elastic',
                    'transitionOut' : 'elastic',
            'href' : this.href.replace(new RegExp("watch\\?v=", "i"), 'v/'),
            'type'      : 'swf',
            'swf'       : {'wmode':'transparent','allowfullscreen':'true'}
        });
</script>

This way if the user javascript is enabled it opens a fancybox with the youtube embed video, if javascript is disabled it opens the video's youtube page. If you want you can add

target="_blank"

to each of your links, it won't validate on most doctypes, but it will open the link in a new window if fancybox doesn't pick it up.

EDIT

this, above, isn't referenced correctly, so the code won't find href under this. You have to call it like this:

$("a.more").click(function() {
    $.fancybox({
            'padding'       : 0,
            'autoScale'     : false,
            'transitionIn'  : 'none',
            'transitionOut' : 'none',
            'title'         : this.title,
            'width'     : 680,
            'height'        : 495,
            'href'          : this.href.replace(new RegExp("watch\\?v=", "i"), 'v/'),
            'type'          : 'swf',
            'swf'           : {
                 'wmode'        : 'transparent',
                'allowfullscreen'   : 'true'
            }
        });

    return false;
});

git fetch [remotename]

However you'll need to merge any changes into your local branches. If you're on a branch that's tracking a remote branch on Github, then

git pull

will first do a fetch, and then merge in the tracked branch

The fastest way to copy a database is to detach-copy-attach method, but the production users will not have database access while the prod db is detached. You can do something like this if your production DB is for example a Point of Sale system that nobody uses during the night.

If you cannot detach the production db you should use backup and restore.

You will have to create the logins if they are not in the new instance. I do not recommend you to copy the system databases.

You can use the SQL Server Management Studio to create the scripts that create the logins you need. Right click on the login you need to create and select Script Login As / Create.

This will lists the orphaned users:

EXEC sp_change_users_login 'Report'

If you already have a login id and password for this user, fix it by doing:

EXEC sp_change_users_login 'Auto_Fix', 'user'

If you want to create a new login id and password for this user, fix it by doing:

EXEC sp_change_users_login 'Auto_Fix', 'user', 'login', 'password'

You can always wrap Double.parseDouble() in a try catch block.

try
{
  Double.parseDouble(number);
}
catch(NumberFormatException e)
{
  //not a double
}

Mount GDrive:

from google.colab import drive
drive.mount('/content/gdrive')

Open the link -> copy authorization code -> paste that into the prompt and press "Enter"

Check GDrive access:

!ls "/content/gdrive/My Drive"

Unzip (q stands for "quiet") file from GDrive:

!unzip -q "/content/gdrive/My Drive/dataset.zip"

Try this:

select nextval('my_seq_name');  // Returns next value

If this return 1 (or whatever is the start_value for your sequence), then reset the sequence back to the original value, passing the false flag:

select setval('my_seq_name', 1, false);

Otherwise,

select setval('my_seq_name', nextValue - 1, true);

This will restore the sequence value to the original state and "setval" will return with the sequence value you are looking for.

var output = '';
for (var property in object) {
  output += property + ': ' + object[property]+'; ';
}
alert(output);

you can use function bellow in order to generate your UUID

create or replace FUNCTION RANDOM_GUID
    RETURN VARCHAR2 IS

    RNG    NUMBER;
    N      BINARY_INTEGER;
    CCS    VARCHAR2 (128);
    XSTR   VARCHAR2 (4000) := NULL;
  BEGIN
    CCS := '0123456789' || 'ABCDEF';
    RNG := 15;

    FOR I IN 1 .. 32 LOOP
      N := TRUNC (RNG * DBMS_RANDOM.VALUE) + 1;
      XSTR := XSTR || SUBSTR (CCS, N, 1);
    END LOOP;

    RETURN SUBSTR(XSTR, 1, 4) || '-' ||
        SUBSTR(XSTR, 5, 4)        || '-' ||
        SUBSTR(XSTR, 9, 4)        || '-' ||
        SUBSTR(XSTR, 13,4)        || '-' ||
        SUBSTR(XSTR, 17,4)        || '-' ||

        SUBSTR(XSTR, 24,4)        || '-' ||
        SUBSTR(XSTR, 28,4);
END RANDOM_GUID;

Example of GUID genedrated by the function above:
8EA4-196D-BC48-9793-8AE8-5500-03DC-9D04

You can change the innerHTML or outerHTML of an element on the page instead.

It tells taskkill that the next parameter something.exe is an image name, a.k.a executable name

C:\>taskkill /?

TASKKILL [/S system [/U username [/P [password]]]]
         { [/FI filter] [/PID processid | /IM imagename] } [/T] [/F]

Description:
    This tool is used to terminate tasks by process id (PID) or image name.

Parameter List:
    /S    system           Specifies the remote system to connect to.

    /U    [domain\]user    Specifies the user context under which the
                           command should execute.

    /P    [password]       Specifies the password for the given user
                           context. Prompts for input if omitted.

    /FI   filter           Applies a filter to select a set of tasks.
                           Allows "*" to be used. ex. imagename eq acme*

    /PID  processid        Specifies the PID of the process to be terminated.
                           Use TaskList to get the PID.

    /IM   imagename        Specifies the image name of the process
                           to be terminated. Wildcard '*' can be used
                           to specify all tasks or image names.

    /T                     Terminates the specified process and any
                           child processes which were started by it.

    /F                     Specifies to forcefully terminate the process(es).

    /?                     Displays this help message.

Cleansing Data in Pig is very easy,a suitable approach would be cleansing data through pig and then processing data through hive and later uploading it to hdfs.

Are you looking to scale upwards but not downwards?

div {
    border: solid 1px green;
    width: 60px;
    height: 70px;
}

div img {
    width: 100%;
    height: 100%;
    min-height: 500px;
    min-width: 500px;
    outline: solid 1px red;
}

This however, does not lock aspect-ratio.

According to @Shovalt's answer, but in short:

Alternatively you could use the following lines of code

    from sklearn.metrics import f1_score
    metrics.f1_score(y_test, y_pred, labels=np.unique(y_pred))

This should remove your warning and give you the result you wanted, because it no longer considers the difference between the sets, by using the unique mode.

Here's a couple of extension methods I've jury-rigged together to convert IQueryables and IEnumerables from one type to another (i.e. DTO). It's mainly used to convert from a larger type (i.e. the type of the row in the database that has unneeded fields) to a smaller one.

The positive sides of this approach are:

• it requires almost no code to use - a simple call to .Transform<DtoType>() is all you need
• it works just like .Select(s=>new{...}) i.e. when used with IQueryable it produces the optimal SQL code, excluding Type1 fields that DtoType doesn't have.

LinqHelper.cs:

public static IQueryable<TResult> Transform<TResult>(this IQueryable source)
{
    var resultType = typeof(TResult);
    var resultProperties = resultType.GetProperties().Where(p => p.CanWrite);

    ParameterExpression s = Expression.Parameter(source.ElementType, "s");

    var memberBindings =
        resultProperties.Select(p =>
            Expression.Bind(typeof(TResult).GetMember(p.Name)[0], Expression.Property(s, p.Name))).OfType<MemberBinding>();

    Expression memberInit = Expression.MemberInit(
        Expression.New(typeof(TResult)),
        memberBindings
        );

    var memberInitLambda = Expression.Lambda(memberInit, s);

    var typeArgs = new[]
        {
            source.ElementType, 
            memberInit.Type
        };

    var mc = Expression.Call(typeof(Queryable), "Select", typeArgs, source.Expression, memberInitLambda);

    var query = source.Provider.CreateQuery<TResult>(mc);

    return query;
}

public static IEnumerable<TResult> Transform<TResult>(this IEnumerable source)
{
    return source.AsQueryable().Transform<TResult>();
}

Here is the Swift 3 answer for anyone looking since Swift 3 does not accept "Make".

aView.center = CGPoint(x: 200, Y: 200)

I built on Guilhermes answer, but I preserve the position of the cursor and also treat the periods differently - this way if a user is typing after the period, it does not affect the numbers before the period I find that this gives a very smooth input.

    [yourtextfield].addTextChangedListener(new TextWatcher()
    {
        NumberFormat currencyFormat = NumberFormat.getCurrencyInstance();
        private String current = "";

        @Override
        public void onTextChanged(CharSequence s, int start, int before, int count)
        {
            if(!s.toString().equals(current))
            {
                   [yourtextfield].removeTextChangedListener(this);

                   int selection = [yourtextfield].getSelectionStart();


                   // We strip off the currency symbol
                   String replaceable = String.format("[%s,\\s]", NumberFormat.getCurrencyInstance().getCurrency().getSymbol());
                   String cleanString = s.toString().replaceAll(replaceable, "");

                   double price;

                   // Parse the string                     
                   try
                   {
                       price = Double.parseDouble(cleanString);
                   }
                   catch(java.lang.NumberFormatException e)
                   {
                       price = 0;
                   }

                   // If we don't see a decimal, then the user must have deleted it.
                   // In that case, the number must be divided by 100, otherwise 1
                   int shrink = 1;
                   if(!(s.toString().contains(".")))
                   {
                       shrink = 100;
                   }

                   // Reformat the number
                   String formated = currencyFormat.format((price / shrink));

                   current = formated;
                   [yourtextfield].setText(formated);
                   [yourtextfield].setSelection(Math.min(selection, [yourtextfield].getText().length()));

                   [yourtextfield].addTextChangedListener(this);
                }
        }


        @Override
        public void beforeTextChanged(CharSequence s, int start, int count, int after)
        {

        }


        @Override
        public void afterTextChanged(Editable s)
        {
        }
    });

I use the following way to handle the many-to-many relationship where only foreign keys are involved.

So for inserting:

public void InsertStudentClass (long studentId, long classId)
{
    using (var context = new DatabaseContext())
    {
        Student student = new Student { StudentID = studentId };
        context.Students.Add(student);
        context.Students.Attach(student);

        Class class = new Class { ClassID = classId };
        context.Classes.Add(class);
        context.Classes.Attach(class);

        student.Classes = new List<Class>();
        student.Classes.Add(class);

        context.SaveChanges();
    }
}

For deleting,

public void DeleteStudentClass(long studentId, long classId)
{
    Student student = context.Students.Include(x => x.Classes).Single(x => x.StudentID == studentId);

    using (var context = new DatabaseContext())
    {
        context.Students.Attach(student);
        Class classToDelete = student.Classes.Find(x => x.ClassID == classId);
        if (classToDelete != null)
        {
            student.Classes.Remove(classToDelete);
            context.SaveChanges();
        }
    }
}

How about

DataSource = null;
DataBind();

Angular provides a number of built-in directives for manipulating CSS styling conditionally/dynamically:

• ng-class - use when the set of CSS styles is static/known ahead of time
• ng-style - use when you can't define a CSS class because the style values may change dynamically. Think programmable control of the style values.
• ng-show and ng-hide - use if you only need to show or hide something (modifies CSS)
• ng-if - new in version 1.1.5, use instead of the more verbose ng-switch if you only need to check for a single condition (modifies DOM)
• ng-switch - use instead of using several mutually exclusive ng-shows (modifies DOM)
• ng-disabled and ng-readonly - use to restrict form element behavior
• ng-animate - new in version 1.1.4, use to add CSS3 transitions/animations

The normal "Angular way" involves tying a model/scope property to a UI element that will accept user input/manipulation (i.e., use ng-model), and then associating that model property to one of the built-in directives mentioned above.

When the user changes the UI, Angular will automatically update the associated elements on the page.

ng-class accepts an "expression" that must evaluate to one of the following:

1. a string of space-delimited class names
2. an array of class names
3. a map/object of class names to boolean values

Assuming your items are displayed using ng-repeat over some array model, and that when the checkbox for an item is checked you want to apply the pending-delete class:

<div ng-repeat="item in items" ng-class="{'pending-delete': item.checked}">
   ... HTML to display the item ...
   <input type="checkbox" ng-model="item.checked">
</div>

Above, we used ng-class expression type #3 - a map/object of class names to boolean values.

ng-style accepts an "expression" that must evaluate to:

1. an map/object of CSS style names to CSS values

For a contrived example, suppose the user can type in a color name into a texbox for the background color (a jQuery color picker would be much nicer):

<div class="main-body" ng-style="{color: myColor}">
   ...
   <input type="text" ng-model="myColor" placeholder="enter a color name">

The fiddle also contains an example of ng-show and ng-hide. If a checkbox is checked, in addition to the background-color turning pink, some text is shown. If 'red' is entered in the textbox, a div becomes hidden.

Use 'q' as the the optional argument to getline.

#include <iostream>
#include <sstream>

int main() {
    std::string numbers_str;
    getline( std::cin, numbers_str, 'q' );

    int number;
    for ( std::istringstream numbers_iss( numbers_str );
          numbers_iss >> number; ) {
        std::cout << number << ' ';
    }
}

You can also do

subset(df, aged <= laclen)

Based on https://github.com/antonyt/InfiniteViewPager I wrote up this which works nicely:

class InfiniteViewPager @JvmOverloads constructor(
  context: Context,
  attrs: AttributeSet? = null
) : ViewPager(context, attrs) {
  // Allow for 100 back cycles from the beginning.
  // This should be enough to create an illusion of infinity.
  // Warning: scrolling to very high values (1,000,000+) results in strange drawing behaviour.
  private val offsetAmount get() = if (adapter?.count == 0) 0 else (adapter as InfinitePagerAdapter).realCount * 100

  override fun setAdapter(adapter: PagerAdapter?) {
    super.setAdapter(if (adapter == null) null else InfinitePagerAdapter(adapter))
    currentItem = 0
  }

  override fun setCurrentItem(item: Int) = setCurrentItem(item, false)

  override fun setCurrentItem(item: Int, smoothScroll: Boolean) {
    val adapterCount = adapter?.count

    if (adapterCount == null || adapterCount == 0) {
      super.setCurrentItem(item, smoothScroll)
    } else {
      super.setCurrentItem(offsetAmount + item % adapterCount, smoothScroll)
    }
  }

  override fun getCurrentItem(): Int {
    val adapterCount = adapter?.count

    return if (adapterCount == null || adapterCount == 0) {
      super.getCurrentItem()
    } else {
      val position = super.getCurrentItem()
      position % (adapter as InfinitePagerAdapter).realCount
    }
  }

  fun animateForward() {
    super.setCurrentItem(super.getCurrentItem() + 1, true)
  }

  fun animateBackwards() {
    super.setCurrentItem(super.getCurrentItem() - 1, true)
  }

  internal class InfinitePagerAdapter(private val adapter: PagerAdapter) : PagerAdapter() {
    internal val realCount: Int get() = adapter.count

    override fun getCount() = if (realCount == 0) 0 else Integer.MAX_VALUE

    override fun instantiateItem(container: ViewGroup, position: Int) = adapter.instantiateItem(container, position % realCount)

    override fun destroyItem(container: ViewGroup, position: Int, `object`: Any) = adapter.destroyItem(container, position % realCount, `object`)

    override fun finishUpdate(container: ViewGroup) = adapter.finishUpdate(container)

    override fun isViewFromObject(view: View, `object`: Any) = adapter.isViewFromObject(view, `object`)

    override fun restoreState(bundle: Parcelable?, classLoader: ClassLoader?) = adapter.restoreState(bundle, classLoader)

    override fun saveState(): Parcelable? = adapter.saveState()

    override fun startUpdate(container: ViewGroup) = adapter.startUpdate(container)

    override fun getPageTitle(position: Int) = adapter.getPageTitle(position % realCount)

    override fun getPageWidth(position: Int) = adapter.getPageWidth(position)

    override fun setPrimaryItem(container: ViewGroup, position: Int, `object`: Any) = adapter.setPrimaryItem(container, position, `object`)

    override fun unregisterDataSetObserver(observer: DataSetObserver) = adapter.unregisterDataSetObserver(observer)

    override fun registerDataSetObserver(observer: DataSetObserver) = adapter.registerDataSetObserver(observer)

    override fun notifyDataSetChanged() = adapter.notifyDataSetChanged()

    override fun getItemPosition(`object`: Any) = adapter.getItemPosition(`object`)
  }
}

For consuming it simply change your ViewPager to InfiniteViewPager and that's all you need to change.

Probably you are trying to access the excel with the index 0, please note that Excel rows/columns start from 1.

Just replace, with replace().

f = float("123,456.908".replace(',','')) print(type(f)

type() will show you that it has converted into a float
