I believe cmp will stop at the first byte difference:

cmp --silent $old $new || echo "files are different"

Here's a self-sufficient JS function that solves this (and other) problems for most European/US locales (primarily between US/German/Swedish number chunking and formatting ... as in the OP). I think it's an improvement on (and inspired by) Slawa's solution, and has no dependencies.

function realParseFloat(s)
{
    s = s.replace(/[^\d,.-]/g, ''); // strip everything except numbers, dots, commas and negative sign
    if (navigator.language.substring(0, 2) !== "de" && /^-?(?:\d+|\d{1,3}(?:,\d{3})+)(?:\.\d+)?$/.test(s)) // if not in German locale and matches #,###.######
    {
        s = s.replace(/,/g, ''); // strip out commas
        return parseFloat(s); // convert to number
    }
    else if (/^-?(?:\d+|\d{1,3}(?:\.\d{3})+)(?:,\d+)?$/.test(s)) // either in German locale or not match #,###.###### and now matches #.###,########
    {
        s = s.replace(/\./g, ''); // strip out dots
        s = s.replace(/,/g, '.'); // replace comma with dot
        return parseFloat(s);
    }
    else // try #,###.###### anyway
    {
        s = s.replace(/,/g, ''); // strip out commas
        return parseFloat(s); // convert to number
    }
}

You can also use the latest keyword to install the most recent version available:

  "dependencies": {
    "fontawesome": "latest"
  }

It's work for me in Spring 4.

@RequestMapping(value = "/image/{id}", method = RequestMethod.GET)
public void findImage(@PathVariable("id") String id, HttpServletResponse resp){

        final Foto anafoto = <find object>
        resp.reset();
        resp.setContentType(MediaType.IMAGE_JPEG_VALUE);
        resp.setContentLength(anafoto.getImage().length);

        final BufferedInputStream in = new BufferedInputStream(new ByteArrayInputStream(anafoto.getImageInBytes()));

        try {
            FileCopyUtils.copy(in, resp.getOutputStream());
            resp.flushBuffer();
        } catch (final IOException e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
        }

}

This page tells you all you need to know about sorting collections, such as ArrayList.

Basically you need to

• make your Contact class implement the Comparable interface by
  • creating a method public int compareTo(Contact anotherContact) within it.
• Once you do this, you can just call Collections.sort(myContactList);,
  • where myContactList is ArrayList<Contact> (or any other collection of Contact).

There's another way as well, involving creating a Comparator class, and you can read about that from the linked page as well.

Example:

public class Contact implements Comparable<Contact> {

    ....

    //return -1 for less than, 0 for equals, and 1 for more than
    public compareTo(Contact anotherContact) {
        int result = 0;
        result = getName().compareTo(anotherContact.getName());
        if (result != 0)
        {
            return result;
        }
        result = getNunmber().compareTo(anotherContact.getNumber());
        if (result != 0)
        {
            return result;
        }
        ...
    }
}

You need to remove the /var/lib/mysql folder. Also, purge when you remove the packages (I'm told this helps).

sudo apt-get remove --purge mysql-server mysql-client mysql-common

sudo rm -rf /var/lib/mysql

I was encountering similar issues. The second line got rid of my issues and allowed me to set up MySql from scratch. Hopefully it helps you too!

You can get the total number of rows containing a specific name using:

SELECT COUNT(*) FROM tbl_foo WHERE name = 'sarmen'

Given the count, you can now get the nth row using:

SELECT * FROM tbl_foo WHERE name = 'sarmen' LIMIT (n - 1), 1

Where 1 <= n <= COUNT(*) from the first query.

Example:

getting the 3rd row

SELECT * FROM tbl_foo WHERE name = 'sarmen' LIMIT 2, 1

So much answers and all them good, but I will suggest my own, maybe it will be usefull for somebody.

We have HTML in the template:

<div class="listing-item-excerpt" id="listing-item-excerpt-<?= $task['id'] ?>">
    <?= mb_substr($txt, 0, 150) ?><span class="complete_txt"><?= mb_substr($txt, 150) ?></span>
    <a href="javascript: show_more_less(<?= $task['id'] ?>);void(0);" class="more_less_btn" data-more-txt="<?= __('... show more') ?>" data-less-txt="&nbsp;<?= __('show less') ?>" data-state="0"><?= __('... show more') ?></a>
</div>

JS function for toggling which:

function show_more_less(task_id) {

    var btn = jQuery('#listing-item-excerpt-' + task_id).find('.more_less_btn');
    var txt_container = jQuery('#listing-item-excerpt-' + task_id).find('.complete_txt');
    var state = parseInt(jQuery(btn).data('state'), 10);
    if (state === 0) {
        jQuery(txt_container).show();
        jQuery(btn).text(jQuery(btn).data('less-txt'));
        jQuery(btn).data('state', 1);
    } else {
        jQuery(txt_container).hide();
        jQuery(btn).text(jQuery(btn).data('more-txt'));
        jQuery(btn).data('state', 0);
    }
}

In order to avoid OutOfMemory error for bigger files, I would solve the task by splitting a bitmap into several parts and merging their parts' bytes.

private byte[] getBitmapBytes(Bitmap bitmap)
{
    int chunkNumbers = 10;
    int bitmapSize = bitmap.getRowBytes() * bitmap.getHeight();
    byte[] imageBytes = new byte[bitmapSize];
    int rows, cols;
    int chunkHeight, chunkWidth;
    rows = cols = (int) Math.sqrt(chunkNumbers);
    chunkHeight = bitmap.getHeight() / rows;
    chunkWidth = bitmap.getWidth() / cols;

    int yCoord = 0;
    int bitmapsSizes = 0;

    for (int x = 0; x < rows; x++)
    {
        int xCoord = 0;
        for (int y = 0; y < cols; y++)
        {
            Bitmap bitmapChunk = Bitmap.createBitmap(bitmap, xCoord, yCoord, chunkWidth, chunkHeight);
            byte[] bitmapArray = getBytesFromBitmapChunk(bitmapChunk);
            System.arraycopy(bitmapArray, 0, imageBytes, bitmapsSizes, bitmapArray.length);
            bitmapsSizes = bitmapsSizes + bitmapArray.length;
            xCoord += chunkWidth;

            bitmapChunk.recycle();
            bitmapChunk = null;
        }
        yCoord += chunkHeight;
    }

    return imageBytes;
}


private byte[] getBytesFromBitmapChunk(Bitmap bitmap)
{
    int bitmapSize = bitmap.getRowBytes() * bitmap.getHeight();
    ByteBuffer byteBuffer = ByteBuffer.allocate(bitmapSize);
    bitmap.copyPixelsToBuffer(byteBuffer);
    byteBuffer.rewind();
    return byteBuffer.array();
}

Step 1: Goto xammp

Step 2: Find php Foleder and click on it,

Find 2: Below php.ini file

Path : C:\xampp\php

Second Example : step 1: Open xampp control panel

Step 2: Click On config,

Step 3: Find Here php.ini file

To get loaded php.ini files location try: command : php --ini

From w3:

The label itself may be positioned before, after or around the associated control.

<label for="lastname">Last Name</label>
<input type="text" id="lastname" />

or

<input type="text" id="lastname" />
<label for="lastname">Last Name</label>

or

<label>
   <input type="text" name="lastname" />
   Last Name
</label>

Note that the third technique cannot be used when a table is being used for layout, with the label in one cell and its associated form field in another cell.

Either one is valid. I like to use either the first or second example, as it gives you more style control.

Add a line to your app.config in the configSections element

<configSections>
 <section name="log4net" 
   type="log4net.Config.Log4NetConfigurationSectionHandler, log4net, Version=1.2.10.0, 
         Culture=neutral, PublicKeyToken=1b44e1d426115821" />
</configSections>

Then later add the log4Net section, but delegate to the actual log4Net config file elsewhere...

<log4net configSource="Config\Log4Net.config" />

In your application code, when you create the log, write

private static ILog GetLog(string logName)
{
    ILog log = LogManager.GetLogger(logName);
    return log;
}

Jenkins stores the console log on master. If you want programmatic access to the log, and you are running on master, you can access the log that Jenkins already has, without copying it to the artifacts or having to GET the http job URL.

From http://javadoc.jenkins.io/archive/jenkins-1.651/hudson/model/Run.html#getLogFile(), this returns the File object for the console output (in the jenkins file system, this is the "log" file in the build output directory).

In my case, we use a chained (child) job to do parsing and analysis on a parent job's build.

When using a groovy script run in Jenkins, you get an object named "build" for the run. We use this to get the http://javadoc.jenkins.io/archive/jenkins-1.651/hudson/model/Build.html for the upstream job, then call this job's .getLogFile().

Added bonus; since it's just a File object, we call .getParent() to get the folder where Jenkins stores build collateral (like test xmls, environment variables, and other things that may not be explicitly exposed through the artifacts) which we can also parse.

Double added bonus; we also use matrix jobs. This sometimes makes inferring the file path on the system a pain. .getLogFile().getParent() takes away all the pain.

If you want to UPDATE a tag, let's say it 1.0.0

1. git checkout 1.0.0
2. make your changes
3. git ci -am 'modify some content'
4. git tag -f 1.0.0
5. delete remote tag on github: git push origin --delete 1.0.0
6. git push origin 1.0.0

DONE

Even-though this is an old thread, i'd like to share my experience as it helped me. My application was working fine for OS 2.0 & 4.0+ but for a HTC phone running OS 3.x the text was not wrapping. What worked for me was to include both of these tags.

android:maxLines="100"
android:scrollHorizontally="false"

If you eliminate either it was not working for only the os 3.0 device. "ellipsize" parameter had neutral effect. Here is the full textview tag below

<TextView
                android:id="@+id/cell_description"
                android:layout_width="fill_parent"
                android:layout_height="wrap_content"
                android:paddingTop="5dp"
                android:maxLines="100"
                android:scrollHorizontally="false"
                android:textStyle="normal"
                android:textSize="11sp"
                android:textColor="@color/listcell_detail"/>

Hope this would help someone.

• Make sure Maps SDK for Android is enabled in API console.
• Also you might need to add your package name and SHA-1 signing-certificate fingerprint to restrict usage for your key to be fully enabled.

You can call JFrame.setLocationRelativeTo(null) to center the window. Make sure to put this before JFrame.setVisible(true)

Just a follow up to @LisaD's answer.
As of 2016 (Django 1.9), you need to type:

heroku pg:reset DATABASE_URL
heroku run python manage.py makemigrations
heroku run python manage.py migrate

This will give you a fresh new database within Heroku.

You can try a blank phrase:

document.add(new Phrase("\n"));

I just tried to get path of shared preferences below like this.This is work for me.

File f = getDatabasePath("MyPrefsFile.xml");

if (f != null)
    Log.i("TAG", f.getAbsolutePath());

Reading @ofavre's and @stanislav-bashkyrtsev's answers using broken GIT submodule references to create the GIT directories, I'm surprised that nobody has suggested yet this simple amendment of the idea to make the whole thing sane and safe:

Rather than hacking a fake submodule into GIT, just add an empty real one.

Enter: https://gitlab.com/empty-repo/empty.git

A GIT repository with exactly one commit:

commit e84d7b81f0033399e325b8037ed2b801a5c994e0
Author: Nobody <none>
Date: Thu Jan 1 00:00:00 1970 +0000

No message, no committed files.

Usage

To add an empty directory to you GIT repo:

git submodule add https://gitlab.com/empty-repo/empty.git path/to/dir

To convert all existing empty directories to submodules:

find . -type d -empty -delete -exec git submodule add -f https://gitlab.com/empty-repo/empty.git \{\} \;

Git will store the latest commit hash when creating the submodule reference, so you don't have to worry about me (or GitLab) using this to inject malicious files. Unfortunately I have not found any way to force which commit ID is used during checkout, so you'll have to manually check that the reference commit ID is e84d7b81f0033399e325b8037ed2b801a5c994e0 using git submodule status after adding the repo.

Still not a native solution, but the best we probably can have without somebody getting their hands really, really dirty in the GIT codebase.

Appendix: Recreating this commit

You should be able to recreate this exact commit using (in an empty directory):

# Initialize new GIT repository
git init

# Set author data (don't set it as part of the `git commit` command or your default data will be stored as “commit author”)
git config --local user.name "Nobody"
git config --local user.email "none"

# Set both the commit and the author date to the start of the Unix epoch (this cannot be done using `git commit` directly)
export GIT_AUTHOR_DATE="Thu Jan 1 00:00:00 1970 +0000"
export GIT_COMMITTER_DATE="Thu Jan 1 00:00:00 1970 +0000"

# Add root commit
git commit --allow-empty --allow-empty-message --no-edit

Creating reproducible GIT commits is surprisingly hard…

In case if you're trying to deploy a project using VSTS, then issue might be connected with checking "Hosted Windows Container" option instead of "Hosted VS2017"(or 18, etc.):

In xcode 8 you can directly choose image from the selection window (NEW)...

• You just need to type - "image" and you will get a suggestion box then select -"Image Literal" from list (see in attached picture) and

• then tap on the square you will be able to see all images(see in
  second attached picture) which are in your image assets... or select other image from there.

• Now tap on square box - (You will see that square box after selecting above option)

if you have permission then

Alias /favicon.ico /var/www/aktel/workspace1/PyBot/PyBot/static/favicon.ico

add alias to your virtual host. (in apache config file ) similarly for robots.txt

Alias /robots.txt /var/www/---your path ---/PyBot/robots.txt

The Sun JVM requires a lot of memory for HotSpot and it maps in the runtime libraries in shared memory.

If memory is an issue consider using another JVM suitable for embedding. IBM has j9, and there is the Open Source "jamvm" which uses GNU classpath libraries. Also Sun has the Squeak JVM running on the SunSPOTS so there are alternatives.

The below code worked fine:

Run Keyword if    '${value1}' \ \ == \ \ '${cost1}' \ and \ \ '${value2}' \ \ == \ \ 'cost2'    LOG    HELLO

$array = explode('.',$string);

Returns an array of split elements.

for (Bullet bullet : gunList.get(2).getBullet()) System.out.println(bullet);

Take a look at the JavaDoc for RestTemplate.

There is the corresponding getForObject methods that are the HTTP GET equivalents of postForObject, but they doesn't appear to fulfil your requirements of "GET with headers", as there is no way to specify headers on any of the calls.

Looking at the JavaDoc, no method that is HTTP GET specific allows you to also provide header information. There are alternatives though, one of which you have found and are using. The exchange methods allow you to provide an HttpEntity object representing the details of the request (including headers). The execute methods allow you to specify a RequestCallback from which you can add the headers upon its invocation.

As @haserman says:

TelephonyManager tManager = (TelephonyManager)myActivity.getSystemService(Context.TELEPHONY_SERVICE);
String uid = tManager.getDeviceId();

But it's necessary including the permission in the manifest file:

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

If you're using a linux server for your application then it is necessary to use lowercase file name and class name to avoid this issue.

Ex.

Filename: csvsample.php

class csvsample {

}

display: inline-block; will prevent break between the words in a list item

 li {
    display: inline-block;
 }

1. literal_eval, a somewhat safer version of eval (will only evaluate literals ie strings, lists etc):

   from ast import literal_eval
   
   python_dict = literal_eval("{'a': 1}")
   

2. json.loads but it would require your string to use double quotes:

   import json
   
   python_dict = json.loads('{"a": 1}')
   

To keep images from stretching in either axis inside a flex parent I have found a couple of solutions.

You can try using object-fit on the image which, e.g.

object-fit: contain;

http://jsfiddle.net/ykw3sfjd/

Or you can add flex-specfic rules which may work better in some cases.

align-self: center;
flex: 0 0 auto;

Its a late answer, but as I can see most of the people mentioned about "refresh" method to redirect a webpage. As per W3C, we should not use "refresh" to redirect. Because it could break the "back" button. Imagine that the user presses the "back" button, the refresh would work again, and the user would bounce forward. The user will most likely get very annoyed, and close the window, which is probably not what you, as the author of this page, want.

Use HTTP redirects instead. One can refer the complete documentation here: W3C document

In JavasSript there are 5 primitive data types String , Number , Boolean , null and undefined. I will try to explain with some simple example

lets say we have a simple function

 function test(a) {

     if(a == null){
        alert("a is null");
     } else {
        alert("The value of a is " + a);
     }
  }

also in above function if(a == null) is same as if(!a)

now when we call this function without passing the parameter a

   test(); it will alert "a is null";
   test(4); it will alert "The value of a is " + 4;

also

var a;
alert(typeof a); 

this will give undefined; we have declared a variable but we have not asigned any value to this variable; but if we write

var a = null;
alert(typeof a); will give alert as object

so null is an object. in a way we have assigned a value null to 'a'

var isWin64 = process.env.hasOwnProperty('ProgramFiles(x86)');

Yes that is correct. "Boolean variables only have two possible values: true (1) and false (0)." cpp tutorial on boolean values

I did some benchmarking where they do the same - sealed types.

var c1 = "";
var c2 = typeof(string);
object oc1 = c1;

The generic functions to test for generic types:

static bool GetType1<S, T>(T t)
{
    return t.GetType() == typeof(S);
}
static bool GetType2<S, T>(T t)
{
    return typeof(T) == typeof(S);
}
static bool Is<S, T>(T t)
{
    return t is S;
}

I tried for custom types as well and the results were consistent:

var c1 = new Class1();
var c2 = new Class2();
object oc1 = c1;
object oc2 = c2;

var s1 = new Struct1();
var s2 = new Struct2();
object os1 = s1;
object os2 = s2;

bool b = false;

Stopwatch sw = Stopwatch.StartNew();
for (int i = 0; i < 10000000; i++)
{
    b = c1.GetType() == typeof(Class1); // ~60ms
    b = c1 is Class1; // ~60ms

    b = c2.GetType() == typeof(Class1); // ~60ms
    b = c2 is Class1; // ~55ms

    b = oc1.GetType() == typeof(Class1); // ~60ms
    b = oc1 is Class1; // ~68ms

    b = oc2.GetType() == typeof(Class1); // ~60ms
    b = oc2 is Class1; // ~68ms


    b = s1.GetType() == typeof(Struct1); // ~150ms
    b = s1 is Struct1; // ~50ms

    b = s2.GetType() == typeof(Struct1); // ~150ms
    b = s2 is Struct1; // ~50ms

    b = os1.GetType() == typeof(Struct1); // ~60ms
    b = os1 is Struct1; // ~64ms

    b = os2.GetType() == typeof(Struct1); // ~60ms
    b = os2 is Struct1; // ~64ms


    b = GetType1<Class1, Class1>(c1); // ~178ms
    b = GetType2<Class1, Class1>(c1); // ~98ms
    b = Is<Class1, Class1>(c1); // ~78ms

    b = GetType1<Class1, Class2>(c2); // ~178ms
    b = GetType2<Class1, Class2>(c2); // ~96ms
    b = Is<Class1, Class2>(c2); // ~69ms

    b = GetType1<Class1, object>(oc1); // ~178ms
    b = Is<Class1, object>(oc1); // ~69ms

    b = GetType1<Class1, object>(oc2); // ~178ms
    b = Is<Class1, object>(oc2); // ~69ms


    b = GetType1<Struct1, Struct1>(s1); // ~272ms
    b = GetType2<Struct1, Struct1>(s1); // ~140ms
    b = Is<Struct1, Struct1>(s1); // ~163ms

    b = GetType1<Struct1, Struct2>(s2); // ~272ms
    b = GetType2<Struct1, Struct2>(s2); // ~140ms
    b = Is<Struct1, Struct2>(s2); // ~163ms

    b = GetType1<Struct1, object>(os1); // ~178ms
    b = Is<Struct1, object>(os1); // ~64ms

    b = GetType1<Struct1, object>(os2); // ~178ms
    b = Is<Struct1, object>(os2); // ~64ms
}

sw.Stop();
MessageBox.Show(sw.Elapsed.TotalMilliseconds.ToString());

And the types:

sealed class Class1 { }
sealed class Class2 { }
struct Struct1 { }
struct Struct2 { }

Inference:

1. Calling GetType on structs is slower. GetType is defined on object class which can't be overridden in sub types and thus structs need to be boxed to be called GetType.

2. On an object instance, GetType is faster, but very marginally.

3. On generic type, if T is class, then is is much faster. If T is struct, then is is much faster than GetType but typeof(T) is much faster than both. In cases of T being class, typeof(T) is not reliable since its different from actual underlying type t.GetType.

In short, if you have an object instance, use GetType. If you have a generic class type, use is. If you have a generic struct type, use typeof(T). If you are unsure if generic type is reference type or value type, use is. If you want to be consistent with one style always (for sealed types), use is..

Just tell request that you are using json:true and forget about header and parse

var options = {
    hostname: '127.0.0.1',
    port: app.get('port'),
    path: '/users',
    method: 'GET',
    json:true
}
request(options, function(error, response, body){
    if(error) console.log(error);
    else console.log(body);
});

and the same for post

var options = {
    hostname: '127.0.0.1',
    port: app.get('port'),
    path: '/users',
    method: 'POST',
    json: {"name":"John", "lastname":"Doe"}
}
request(options, function(error, response, body){
    if(error) console.log(error);
    else console.log(body);
});

You don't need a function for it - simply use the bracket notation:

var side = columns['right'];

This is equal to dot notation, var side = columns.right;, except the fact that right could also come from a variable, function return value, etc., when using bracket notation.

If you NEED a function for it, here it is:

function read_prop(obj, prop) {
    return obj[prop];
}

To answer some of the comments below that aren't directly related to the original question, nested objects can be referenced through multiple brackets. If you have a nested object like so:

var foo = { a: 1, b: 2, c: {x: 999, y:998, z: 997}};

you can access property x of c as follows:

var cx = foo['c']['x']

If a property is undefined, an attempt to reference it will return undefined (not null or false):

foo['c']['q'] === null
// returns false

foo['c']['q'] === false
// returns false

foo['c']['q'] === undefined
// returns true

Well, according to me to it is O(2^n) as in this function only recursion is taking the considerable time (divide and conquer). We see that, the above function will continue in a tree until the leaves are approaches when we reach to the level F(n-(n-1)) i.e. F(1). So, here when we jot down the time complexity encountered at each depth of tree, the summation series is:

1+2+4+.......(n-1)
= 1((2^n)-1)/(2-1)
=2^n -1

that is order of 2^n [ O(2^n) ].

In Ruby and Bash, you can use $ inside parentheses.

/(\S+?)/(\d{4}-\d{2}-\d{2})-(\d+)(/|$)

(This solution is similar to Pete Boughton's, but preserves the usage of $, which means end of line, rather than using \z, which means end of string.)

Absolutely, divs can have more than one class and with some Bootstrap components you'll often need to have multiple classes for them to function as you want them to. Applying multiple classes of course is possible outside of bootstrap as well. All you have to do is separate each class with a space.

Example below:

<label class="checkbox inline">
   <input type="checkbox" id="inlineCheckbox1" value="option1"> 1
</label>

Something like this may work...

@{
    var base64 = Convert.ToBase64String(Model.ByteArray);
    var imgSrc = String.Format("data:image/gif;base64,{0}", base64);
}

<img src="@imgSrc" />

As mentioned in the comments below, please use the above armed with the knowledge that although this may answer your question it may not solve your problem. Depending on your problem this may be the solution but I wouldn't completely rule out accessing the database twice.

document.getElementById() only takes one argument. You can give them a class name and use getElementsByClassName() .

Thank you printf! In a Linux environment, here's a better way to have only one file run the show. Say you have two files, mongoCmds.js with multiple commands:

use someDb
db.someColl.find()

and then the driver shell file, runMongoCmds.sh

mongo < mongoCmds.js

Instead, have just one file, runMongoCmds.sh containing

printf "use someDb\ndb.someColl.find()" | mongo

Bash's printf is much more robust than echo and allows for the \n between commands to force them on multiple lines.

As noted by Josh M, this does not provide a compliant GUID however, but this works well for my current need.

Most common use (other than to declare constants) is an include guard.

%1 refers to the first argument passed in and can't be used in an iterator.

Try this:

Try this one,

1. Create rounded_edittext.xml file in your Drawable

   <?xml version="1.0" encoding="utf-8"?>
   <shape xmlns:android="http://schemas.android.com/apk/res/android"
       android:shape="rectangle" android:padding="15dp">
   
       <solid android:color="#FFFFFF" />
       <corners
           android:bottomRightRadius="0dp"
           android:bottomLeftRadius="0dp"
           android:topLeftRadius="0dp"
           android:topRightRadius="0dp" />
       <stroke android:width="1dip" android:color="#f06060" />
   </shape>
   

2. Apply background for your EditText in xml file

   <EditText
       android:id="@+id/edit_expiry_date"
       android:layout_width="match_parent"
       android:layout_height="wrap_content"
       android:padding="10dip"
       android:background="@drawable/rounded_edittext"
       android:hint="@string/shop_name"
       android:inputType="text" />  
   

3. You will get output like this

Remove numbers, underscore, white-spaces and special characters from the string sentence.

str.replace(/[0-9`~!@#$%^&*()_|+\-=?;:'",.<>\{\}\[\]\\\/]/gi,'');

Demo

16x16 pixels, *.ico format.

As per your requirement, Thread.Sleep is perfectly fine to use because you are not sure when the data will be available so you might need to wait for the data to become available. I have slightly changed the logic of your function this might help you little further.

string SendCmd(string cmd, string ip, int port)
{
    var client = new TcpClient(ip, port);
    var data = Encoding.GetEncoding(1252).GetBytes(cmd);
    var stm = client.GetStream();
    stm.Write(data, 0, data.Length);
    byte[] resp = new byte[2048];
    var memStream = new MemoryStream();

    int bytes = 0;

    do
    {
        bytes = 0;
        while (!stm.DataAvailable)
            Thread.Sleep(20); // some delay
        bytes = stm.Read(resp, 0, resp.Length);
        memStream.Write(resp, 0, bytes);
    } 
    while (bytes > 0);

    return Encoding.GetEncoding(1252).GetString(memStream.ToArray());
}

Hope this helps!

If you are using C++ and don't want/can't use Boost, you can print backtrace with demangled names using the following code [link to the original site].

Note, this solution is specific to Linux. It uses GNU's libc functions backtrace()/backtrace_symbols() (from execinfo.h) to get the backtraces and then uses __cxa_demangle() (from cxxabi.h) for demangling the backtrace symbol names.

Actually you have to Do Like below Example, which will help to Solve the Issue...

drop table ABC_table

create table ABC_table
(
    names varchar(20),
    age int
)

ALTER TABLE ABC_table
ADD CONSTRAINT MyConstraintName
DEFAULT 'This is not NULL' FOR names

insert into ABC(age) values(10)

select * from ABC

If you want to call functions on components from outside React, you can call them on the return value of renderComponent:

var Child = React.createClass({…});
var myChild = React.renderComponent(Child);
myChild.someMethod();

The only way to get a handle to a React Component instance outside of React is by storing the return value of React.renderComponent. Source.

Here's stored procedure, which will generate the table based on data from one table and column and data from other table and column.

The function 'sum(if(col = value, 1,0)) as value ' is used. You can choose from different functions like MAX(if()) etc.

delimiter //

  create procedure myPivot(
    in tableA varchar(255),
    in columnA varchar(255),
    in tableB varchar(255),
    in columnB varchar(255)
)
begin
  set @sql = NULL;
    set @sql = CONCAT('select group_concat(distinct concat(
            \'SUM(IF(', 
        columnA, 
        ' = \'\'\',',
        columnA,
        ',\'\'\', 1, 0)) AS \'\'\',',
        columnA, 
            ',\'\'\'\') separator \', \') from ',
        tableA, ' into @sql');
    -- select @sql;

    PREPARE stmt FROM @sql;
    EXECUTE stmt;

    DEALLOCATE PREPARE stmt;
    -- select @sql;

    SET @sql = CONCAT('SELECT p.', 
        columnB, 
        ', ', 
        @sql, 
        ' FROM ', tableB, ' p GROUP BY p.',
        columnB,'');

You'll also get this exception if you try to save to an invalid path or if there's a permissions issue.

If you're not 100% sure that the file path is available and permissions are correct then try writing a to a text file. This takes just a few seconds to rule out what would be a very simple fix.

var img = System.Drawing.Image.FromStream(incomingStream);

// img.Save(path);
System.IO.File.WriteAllText(path, "Testing valid path & permissions.");

And don't forget to clean up your file.

You can use strcmp:

break x:20 if strcmp(y, "hello") == 0

20 is line number, x can be any filename and y can be any variable.

Storm's answer is not correct. No hard feelings Storm, and apologies to the OP as I'm a bit late to the party here (wish I could have helped sooner, but I didn't run into the problem until today, or this stack overflow answer until I was figuring out a solution.)

The Visual C++ 2003 runtime was not available as a seperate download because it was included with the .NET 1.1 runtime.

If you install the .NET 1.1 runtime you will get msvcr71.dll installed, and in addition added to C:\WINDOWS\Microsoft.NET\Framework\v1.1.4322.

The .NET 1.1 runtime is available here: http://www.microsoft.com/downloads/en/details.aspx?familyid=262d25e3-f589-4842-8157-034d1e7cf3a3&displaylang=en (23.1 MB)

If you are looking for a file that ends with a "P" such as msvcp71.dll, this indicates that your file was compiled against a C++ runtime (as opposed to a C runtime), in some situations I noticed these files were only installed when I installed the full SDK. If you need one of these files, you may need to install the full .NET 1.1 SDK as well, which is available here: http://www.microsoft.com/downloads/en/details.aspx?FamilyID=9b3a2ca6-3647-4070-9f41-a333c6b9181d (106.2 MB)

After installing the SDK I now have both msvcr71.dll and msvcp71.dll in my System32 folder, and the application I'm trying to run (boomerang c++ decompiler) works fine without any missing DLL errors.

Also on a side note: be VERY aware of the difference between a Hotfix Update and a Regular Update. As noted in the linked KB932298 download (linked below by Storm): "Please be aware this Hotfix has not gone through full Microsoft product regression testing nor has it been tested in combination with other Hotfixes."

Hotfixes are NOT meant for general users, but rather users who are facing a very specific problem. As described in the article only install that Hotfix if you are have having specific daylight savings time issues with the rules that changed in 2007. -- Likely this was a pre-release for customers who "just couldn't wait" for the official update (probably for some business critical application) -- for regular users Windows Update should be all you need.

Thanks, and I hope this helps others who run into this issue!

You can run a JAR file from the command line like this:

java -jar myJARFile.jar

Michael Krelin's answer is close is not entirely safe, since it can be wrong in rare situations. The problem is that intervals in PostgreSQL do not have context with regards to things like daylight savings. Intervals store things internally as months, days, and seconds. Months aren't an issue in this case since subtracting two timestamps just use days and seconds but 'days' can be a problem.

If your subtraction involves daylight savings change-overs, a particular day might be considered 23 or 25 hours respectively. The interval will take that into account, which is useful for knowing the amount of days that passed in the symbolic sense but it would give an incorrect number of the actual hours that passed. Epoch on the interval will just multiply all days by 24 hours.

For example, if a full 'short' day passes and an additional hour of the next day, the interval will be recorded as one day and one hour. Which converted to epoch/3600 is 25 hours. But in reality 23 hours + 1 hour should be a total of 24 hours.

So the safer method is:

(EXTRACT(EPOCH FROM current_timestamp) - EXTRACT(EPOCH FROM somedate))/3600

As Michael mentioned in his follow-up comment, you'll also probably want to use floor() or round() to get the result as an integer value.

Use below line of code in the case of Spring Boot Application Add in Spring Boot Main Class @EntityScan(basePackageClasses=YourClassName.class)

Java 8 added a new API for working with dates and times. With Java 8 you can use

import java.time.Instant
...
long unixTimestamp = Instant.now().getEpochSecond();

Instant.now() returns an Instant that represents the current system time. With getEpochSecond() you get the epoch seconds (unix time) from the Instant.

You can use the Firefox add-on called SQLite Manager to view the database's structure clearly.

To return the whole table at once you could change the SELECT to:

SELECT  ...
BULK COLLECT INTO T
FROM    ...

This is only advisable for results that aren't excessively large, since they all have to be accumulated in memory before being returned; otherwise consider the pipelined function as suggested by Charles, or returning a REF CURSOR.

First try to open the file with a decompiler such as ILSpy, your dll might be corrupt. I had this error on an online web site, when I downloaded the dll and tried to open it, it was corrupt, probably some error occurred while uploading it via ftp.

There is simpler approach to decode a ByteBuffer into a String without any problems, mentioned by Andy Thomas.

String s = StandardCharsets.UTF_8.decode(byteBuffer).toString();

The following works:

from bs4 import BeautifulSoup

soup = BeautifulSoup('<META NAME="City" content="Austin">', 'html.parser')

metas = soup.find_all("meta")

for meta in metas:
    print meta.attrs['content'], meta.attrs['name']

Just look at this one it will helps.

Starting with Go 1.16, use os.ReadFile to load the file to memory, use os.WriteFile to write to a file from memory.

Be careful with the os.ReadFile because it reads the whole file into memory.

package main

import "os"

func main() {
    b, err := os.ReadFile("input.txt")
    if err != nil {
        log.Fatal(err)
    }

    // `data` contains everything your file does
    // This writes it to the Standard Out
    os.Stdout.Write(data)

    // You can also write it to a file as a whole
    err = os.WriteFile("destination.txt", b, 0644)
    if err != nil {
        log.Fatal(err)
    }
}

what is about this? \D(\d{5})\D

This will do on:

Beware of using vars as the target directory name for WORKDIR - doing that appears to result in a "cannot normalize nothing" fatal error. IMO, it's also worth pointing out that WORKDIR behaves in the same way as mkdir -p <path> i.e. all elements of the path are created if they don't exist already.

UPDATE: I encountered the variable related problem (mentioned above) whilst running a multi-stage build - it now appears that using a variable is fine - if it (the variable) is "in scope" e.g. in the following, the 2nd WORKDIR reference fails ...

FROM <some image>
ENV varname varval
WORKDIR $varname

FROM <some other image>
WORKDIR $varname

whereas, it succeeds in this ...

FROM <some image>
ENV varname varval
WORKDIR $varname

FROM <some other image>
ENV varname varval
WORKDIR $varname

You can either use tsc --declaration fileName.ts like Ryan describes, or you can specify declaration: true under compilerOptionsin your tsconfig.json assuming you've already had a tsconfig.json under your project.

In my case, I had to remove this line:

    <application
         android:debuggable="false"  <!-- Remove this line -->
         ..../>

From Application tag in my Manifest file.

1. In Notepad++ go to Plugins > Plugin manager > Show Plugin Manager then find Xml Tools plugin. Tick the box and click Install

   

2. Open XML document you want to validate and click Ctrl+Shift+Alt+M (Or use Menu if this is your preference Plugins > XML Tools > Validate Now).
   Following dialog will open:

3. Click on .... Point to XSD file and I am pretty sure you'll be able to handle things from here.

Hope this saves you some time.

EDIT: Plugin manager was not included in some versions of Notepad++ because many users didn't like commercials that it used to show. If you want to keep an older version, however still want plugin manager, you can get it on github, and install it by extracting the archive and copying contents to plugins and updates folder.
In version 7.7.1 plugin manager is back under a different guise... Plugin Admin so now you can simply update notepad++ and have it back.

I guess you can use:

$sql = "UPDATE `some_table` SET `txid`= '$txid', `data` = '$data' WHERE `wallet` = '$wallet'";
if ($mysqli->query($sql, $con)) {
    print "wallet $wallet updated";
}else{
    printf("Errormessage: %s\n", $con->error);
}
$con->close();

You get undefined for the various scenarios:

You declare a variable with var but never set it.

var foo; 
alert(foo); //undefined.

You attempt to access a property on an object you've never set.

var foo = {};
alert(foo.bar); //undefined

You attempt to access an argument that was never provided.

function myFunction (foo) {
  alert(foo); //undefined.
}

As cwolves pointed out in a comment on another answer, functions that don't return a value.

function myFunction () {
}
alert(myFunction());//undefined

A null usually has to be intentionally set on a variable or property (see comments for a case in which it can appear without having been set). In addition a null is of type object and undefined is of type undefined.

I should also note that null is valid in JSON but undefined is not:

JSON.parse(undefined); //syntax error
JSON.parse(null); //null

The code given in the question can be better written as follows

function checkIfArrayIsUnique(myArray) 
    {
        for (var i = 0; i < myArray.length; i++) 
        {
            for (var j = i+1; j < myArray.length; j++) 
            {                  
                    if (myArray[i] == myArray[j]) 
                    {
                        return true; // means there are duplicate values
                    }

            }
        }
        return false; // means there are no duplicate values.
    }

Place the above code at the beginning of your script and the subsequent code will run in 32bit mode with access to the 32bit ODBC drivers. Source.

You need to store the returned function and call it to unsubscribe from the event.

var deregisterListener = $scope.$on("onViewUpdated", callMe);
deregisterListener (); // this will deregister that listener

This is found in the source code :) at least in 1.0.4. I'll just post the full code since it's short

/**
  * @param {string} name Event name to listen on.
  * @param {function(event)} listener Function to call when the event is emitted.
  * @returns {function()} Returns a deregistration function for this listener.
  */
$on: function(name, listener) {
    var namedListeners = this.$$listeners[name];
    if (!namedListeners) {
      this.$$listeners[name] = namedListeners = [];
    }
    namedListeners.push(listener);

    return function() {
      namedListeners[indexOf(namedListeners, listener)] = null;
    };
},

Also, see the docs.

There isn't an explicit concept of a callback function in C++. Callback mechanisms are often implemented via function pointers, functor objects, or callback objects. The programmers have to explicitly design and implement callback functionality.

Edit based on feedback:

In spite of the negative feedback this answer has received, it is not wrong. I'll try to do a better job of explaining where I'm coming from.

C and C++ have everything you need to implement callback functions. The most common and trivial way to implement a callback function is to pass a function pointer as a function argument.

However, callback functions and function pointers are not synonymous. A function pointer is a language mechanism, while a callback function is a semantic concept. Function pointers are not the only way to implement a callback function - you can also use functors and even garden variety virtual functions. What makes a function call a callback is not the mechanism used to identify and call the function, but the context and semantics of the call. Saying something is a callback function implies a greater than normal separation between the calling function and the specific function being called, a looser conceptual coupling between the caller and the callee, with the caller having explicit control over what gets called. It is that fuzzy notion of looser conceptual coupling and caller-driven function selection that makes something a callback function, not the use of a function pointer.

For example, the .NET documentation for IFormatProvider says that "GetFormat is a callback method", even though it is just a run-of-the-mill interface method. I don't think anyone would argue that all virtual method calls are callback functions. What makes GetFormat a callback method is not the mechanics of how it is passed or invoked, but the semantics of the caller picking which object's GetFormat method will be called.

Some languages include features with explicit callback semantics, typically related to events and event handling. For example, C# has the event type with syntax and semantics explicitly designed around the concept of callbacks. Visual Basic has its Handles clause, which explicitly declares a method to be a callback function while abstracting away the concept of delegates or function pointers. In these cases, the semantic concept of a callback is integrated into the language itself.

C and C++, on the other hand, does not embed the semantic concept of callback functions nearly as explicitly. The mechanisms are there, the integrated semantics are not. You can implement callback functions just fine, but to get something more sophisticated which includes explicit callback semantics you have to build it on top of what C++ provides, such as what Qt did with their Signals and Slots.

In a nutshell, C++ has what you need to implement callbacks, often quite easily and trivially using function pointers. What it does not have is keywords and features whose semantics are specific to callbacks, such as raise, emit, Handles, event +=, etc. If you're coming from a language with those types of elements, the native callback support in C++ will feel neutered.

origin/master is an entity (since it is not a physical branch) representing the state of the master branch on the remote origin.

origin master is the branch master on the remote origin.

So we have these:

• origin/master ( A representation or a pointer to the remote branch)
• master - (actual branch)
• <Your_local_branch> (actual branch)
• <Your_local_branch4> (actual branch)
• <Your_local_branch4> (actual branch)

Example (in local branch master):

git fetch # get current state of remote repository
git merge origin/master # merge state of remote master branch into local branch
git push origin master # push local branch master to remote branch master

Use a JSON parser, like JSON.NET

string json = "{ \"Atlantic/Canary\": \"GMT Standard Time\", \"Europe/Lisbon\": \"GMT Standard Time\", \"Antarctica/Mawson\": \"West Asia Standard Time\", \"Etc/GMT+3\": \"SA Eastern Standard Time\", \"Etc/GMT+2\": \"UTC-02\", \"Etc/GMT+1\": \"Cape Verde Standard Time\", \"Etc/GMT+7\": \"US Mountain Standard Time\", \"Etc/GMT+6\": \"Central America Standard Time\", \"Etc/GMT+5\": \"SA Pacific Standard Time\", \"Etc/GMT+4\": \"SA Western Standard Time\", \"Pacific/Wallis\": \"UTC+12\", \"Europe/Skopje\": \"Central European Standard Time\", \"America/Coral_Harbour\": \"SA Pacific Standard Time\", \"Asia/Dhaka\": \"Bangladesh Standard Time\", \"America/St_Lucia\": \"SA Western Standard Time\", \"Asia/Kashgar\": \"China Standard Time\", \"America/Phoenix\": \"US Mountain Standard Time\", \"Asia/Kuwait\": \"Arab Standard Time\" }";
var data = (JObject)JsonConvert.DeserializeObject(json);
string timeZone = data["Atlantic/Canary"].Value<string>();

Ok. I found a program buried deep in other files from the beginning of the year that does what I want. I can't really comment on the suggestions offered because I'm not an experienced spim or low level programmer.Here it is:

The Splatting Operator

To create an array, we create a variable and assign the array. Arrays are noted by the "@" symbol. Let's take the discussion above and use an array to connect to multiple remote computers:

$strComputers = @("Server1", "Server2", "Server3")<enter>

They are used for arrays and hashes.

PowerShell Tutorial 7: Accumulate, Recall, and Modify Data

Array Literals In PowerShell

In bootstrap 4 use:

<ul class="nav navbar-nav ml-auto">

This will push the navbar to the right. Use mr-auto to push it to the left, this is the default behaviour.

What database are you using? normally you don't save files to a database but i think sql 2008 has support for it...

A file is binary data hence UTF 8 does not matter here..

UTF 8 matters when you try to convert a string to a byte array... not a file to byte array.

I noticed that there is localDB in the path that you mentioned above and has the version v11.0. So I entered (LocalDB\V11.0) in Add Connection dialogue and it worked for me.

You want a capture group.

p = re.compile("name (.*) is valid", re.flags) # parentheses for capture groups
print p.match(s).groups() # This gives you a tuple of your matches.

WebSockets is definitely the future.

Long polling is a dirty workaround to prevent creating connections for each request like AJAX does -- but long polling was created when WebSockets didn't exist. Now due to WebSockets, long polling is going away.

WebRTC allows for peer-to-peer communication.

I recommend learning WebSockets.

Comparison:

of different communication techniques on the web

• AJAX - request → response. Creates a connection to the server, sends request headers with optional data, gets a response from the server, and closes the connection. Supported in all major browsers.

• Long poll - request → wait → response. Creates a connection to the server like AJAX does, but maintains a keep-alive connection open for some time (not long though). During connection, the open client can receive data from the server. The client has to reconnect periodically after the connection is closed, due to timeouts or data eof. On server side it is still treated like an HTTP request, same as AJAX, except the answer on request will happen now or some time in the future, defined by the application logic. support chart (full) | wikipedia

• WebSockets - client ↔ server. Create a TCP connection to the server, and keep it open as long as needed. The server or client can easily close the connection. The client goes through an HTTP compatible handshake process. If it succeeds, then the server and client can exchange data in both directions at any time. It is efficient if the application requires frequent data exchange in both ways. WebSockets do have data framing that includes masking for each message sent from client to server, so data is simply encrypted. support chart (very good) | wikipedia

• WebRTC - peer ↔ peer. Transport to establish communication between clients and is transport-agnostic, so it can use UDP, TCP or even more abstract layers. This is generally used for high volume data transfer, such as video/audio streaming, where reliability is secondary and a few frames or reduction in quality progression can be sacrificed in favour of response time and, at least, some data transfer. Both sides (peers) can push data to each other independently. While it can be used totally independent from any centralised servers, it still requires some way of exchanging endPoints data, where in most cases developers still use centralised servers to "link" peers. This is required only to exchange essential data for establishing a connection, after which a centralised server is not required. support chart (medium) | wikipedia

• Server-Sent Events - client ← server. Client establishes persistent and long-term connection to server. Only the server can send data to a client. If the client wants to send data to the server, it would require the use of another technology/protocol to do so. This protocol is HTTP compatible and simple to implement in most server-side platforms. This is a preferable protocol to be used instead of Long Polling. support chart (good, except IE) | wikipedia

Advantages:

The main advantage of WebSockets server-side, is that it is not an HTTP request (after handshake), but a proper message based communication protocol. This enables you to achieve huge performance and architecture advantages. For example, in node.js, you can share the same memory for different socket connections, so they can each access shared variables. Therefore, you don't need to use a database as an exchange point in the middle (like with AJAX or Long Polling with a language like PHP). You can store data in RAM, or even republish between sockets straight away.

Security considerations

People are often concerned about the security of WebSockets. The reality is that it makes little difference or even puts WebSockets as better option. First of all, with AJAX, there is a higher chance of MITM, as each request is a new TCP connection that is traversing through internet infrastructure. With WebSockets, once it's connected it is far more challenging to intercept in between, with additionally enforced frame masking when data is streamed from client to server as well as additional compression, which requires more effort to probe data. All modern protocols support both: HTTP and HTTPS (encrypted).

P.S.

Remember that WebSockets generally have a very different approach of logic for networking, more like real-time games had all this time, and not like http.

The Difference

There are a few characters which can indicate a new line. The usual ones are these two:

* '\n' or '0x0A' (10 in decimal) -> This character is called "Line Feed" (LF).
* '\r' or '0x0D' (13 in decimal) -> This one is called "Carriage return" (CR).

Different Operating Systems handle newlines in a different way. Here is a short list of the most common ones:

* DOS and Windows

They expect a newline to be the combination of two characters, namely '\r\n' (or 13 followed by 10).

* Unix (and hence Linux as well)

Unix uses a single '\n' to indicate a new line.

* Mac

Macs use a single '\r'.

on unix systems, use the system kernel to generate a uuid for you.

I'm assuming you are using jQuery or something similar. If you are using jQuery, then the following should work:

<html>
<head>
   <script src="jquery.js" type="text/javascript"></script>
</head>
<body>
   content
</body>
<script type="text/javascript">
   $("body").load(url);
</script>
</html>

buildscript {
    repositories {
        mavenCentral()
    }
    dependencies {
        classpath 'com.android.tools.build:gradle:0.5.+'
    }
}
apply plugin: 'android'

repositories {
    mavenCentral()
    maven {
        url 'http://maven2.javacv.googlecode.com/git/'
    }
}

dependencies {
    compile 'com.android.support:support-v4:13.0.+'
    compile 'com.googlecode.javacv:javacv:0.5'
    instrumentTestCompile 'junit:junit:4.4'
}

android {
    compileSdkVersion 14
    buildToolsVersion "17.0.0"

    defaultConfig {
        minSdkVersion 7
        targetSdkVersion 14
    }
}

This is worked for me :)

If you use T instead of t there is no need to jump back because the new tab will be opened, but vim's focus will simply remain within NERDTree.

SELECT @LastChangeDate = GETDATE()

I don't understand why the files were relocated to /platform-tools from /tools. It seems ALL development tools I have tried, appcelerator for one, have their setup software look for these files in /tools and fail setup. The "work around" involves a few different bits of trickery wherein you either...1) set up a soft link to tell the operating system "if you look for file "x" here it is really over here. or 2) simpler method ... make a copy of all the /platform-tools default (pre-additional android sdk installations) files and place them into the /tools folder. this circumvents the relocation that the newer sdk have done. Then of course YOU MUST SET PATH ENVIRONMENT VARIABLES TO POINT TO THE SDK LOCATION (sometimes to the Android-sdk-[operating system name:Android-sdk-windows or Android-sdk-mac_x86 ect. ] and to the /platform-tools and sometimes to /tools. it is a trial and error pain. But when it finally is working ...it works.

Building upon the psutil solution mentioned by Joe (only works for checking local ports):

import psutil
1111 in [i.laddr.port for i in psutil.net_connections()]

returns True if port 1111 currently used.

psutil is not part of python stdlib, so you'd need to pip install psutil first. It also needs python headers to be available, so you need something like python-devel

Look at the following example code:

public class MyWorker
{
    public SharedData state;
    public void DoWork(SharedData someData)
    {
        this.state = someData;
        while (true) ;
    }

}

public class SharedData {
    X myX;
    public getX() { etc
    public setX(anX) { etc

}

public class Program
{
    public static void Main()
    {
        SharedData data = new SharedDate()
        MyWorker work1 = new MyWorker(data);
        MyWorker work2 = new MyWorker(data);
        Thread thread = new Thread(new ThreadStart(work1.DoWork));
        thread.Start();
        Thread thread2 = new Thread(new ThreadStart(work2.DoWork));
        thread2.Start();
    }
}

In this case, the thread class MyWorker has a variable state. We initialise it with the same object. Now you can see that the two workers access the same SharedData object. Changes made by one worker are visible to the other.

You have quite a few remaining issues. How does worker 2 know when changes have been made by worker 1 and vice-versa? How do you prevent conflicting changes? Maybe read: this tutorial.

This is what I put as a menu option where I made a button on a JFrame to display another JFrame. I wanted only the new frame to be visible, and not to destroy the one behind it. I initially hid the first JFrame, while the new one became visible. Upon closing of the new JFrame, I disposed of it followed by an action of making the old one visible again.

Note: The following code expands off of Ravinda's answer and ng is a JButton:

ng.addActionListener((ActionEvent e) -> {
    setVisible(false);
    JFrame j = new JFrame("NAME");
    j.setVisible(true);
    j.addWindowListener(new java.awt.event.WindowAdapter() {
        @Override
        public void windowClosing(java.awt.event.WindowEvent windowEvent) {
            setVisible(true);
        }
    });
});

Here is a solution without relying on any server-side control, just like OP has described in the question.

Client side HTML code:

<form action="upload.aspx" method="post" enctype="multipart/form-data">
    <input type="file" name="UploadedFile" />
</form>

Page_Load method of upload.aspx :

if(Request.Files["UploadedFile"] != null)
{
    HttpPostedFile MyFile = Request.Files["UploadedFile"];
    //Setting location to upload files
    string TargetLocation = Server.MapPath("~/Files/");
    try
    {
        if (MyFile.ContentLength > 0)
        {
            //Determining file name. You can format it as you wish.
            string FileName = MyFile.FileName;
            //Determining file size.
            int FileSize = MyFile.ContentLength;
            //Creating a byte array corresponding to file size.
            byte[] FileByteArray = new byte[FileSize];
            //Posted file is being pushed into byte array.
            MyFile.InputStream.Read(FileByteArray, 0, FileSize);
            //Uploading properly formatted file to server.
            MyFile.SaveAs(TargetLocation + FileName);
        }
    }
    catch(Exception BlueScreen)
    {
        //Handle errors
    }
}

Use git diff with a range.

git diff branch1..branch2

This will compare the tips of each branch.

If you really want some GUI software, you can try something like SourceTree which supports Mac OS X and Windows.

I recently blogged about this. My implementation does not use any string operations during the calculations, which makes it very fast. Conversion to any numeral system with base from 2 to 36 is supported:

/// <summary>
/// Converts the given decimal number to the numeral system with the
/// specified radix (in the range [2, 36]).
/// </summary>
/// <param name="decimalNumber">The number to convert.</param>
/// <param name="radix">The radix of the destination numeral system (in the range [2, 36]).</param>
/// <returns></returns>
public static string DecimalToArbitrarySystem(long decimalNumber, int radix)
{
    const int BitsInLong = 64;
    const string Digits = "0123456789ABCDEFGHIJKLMNOPQRSTUVWXYZ";

    if (radix < 2 || radix > Digits.Length)
        throw new ArgumentException("The radix must be >= 2 and <= " + Digits.Length.ToString());

    if (decimalNumber == 0)
        return "0";

    int index = BitsInLong - 1;
    long currentNumber = Math.Abs(decimalNumber);
    char[] charArray = new char[BitsInLong];

    while (currentNumber != 0)
    {
        int remainder = (int)(currentNumber % radix);
        charArray[index--] = Digits[remainder];
        currentNumber = currentNumber / radix;
    }

    string result = new String(charArray, index + 1, BitsInLong - index - 1);
    if (decimalNumber < 0)
    {
        result = "-" + result;
    }

    return result;
}

I've also implemented a fast inverse function in case anyone needs it too: Arbitrary to Decimal Numeral System.

Given some of the answers, to get the actual swap and RAM for a single application I came up with the following, say we want to know what 'firefox' is using

sudo smem | awk '/firefox/{swap+=$5; pss+=$7;}END{print "swap = "swap/1024" PSS = "pss/1024}'
or for libvirt;
sudo smem | awk '/libvirt/{swap+=$5; pss+=$7;}END{print "swap = "swap/1024" PSS = "pss/1024}'

this will give you the total in MB like so;

swap = 0 PSS = 2096.92
swap = 224.75 PSS = 421.455

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

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

SELECT Name, Name FROM Segment ORDER BY 1

create table my_table (
    id_part1 int not null,
    id_part2 int not null,
    primary key (id_part1, id_part2)
)

I had this problem too. For me, the reason was that I was doing

return
commit

instead of

commit
return   

in one stored procedure.

I am just providing another case where you can get this error message. The solution will be the same as Adam has mentioned above. This is from a real code and I renamed the class name.

class FooReader {
  public:
     /** Constructor */
     FooReader() : d(new FooReaderPrivate(this)) { }  // will not compile here
     .......
  private:
     FooReaderPrivate* d;
};

====== In a separate file =====
class FooReaderPrivate {
  public:
     FooReaderPrivate(FooReader*) : parent(p) { }
  private:
     FooReader* parent;
};

The above will no pass the compiler and get error: invalid use of incomplete type FooReaderPrivate. You basically have to put the inline portion into the *.cpp implementation file. This is OK. What I am trying to say here is that you may have a design issue. Cross reference of two classes may be necessary some cases, but I would say it is better to avoid them at the start of the design. I would be wrong, but please comment then I will update my posting.

bool = bool != true;

One of the cases.

Your "bad" output is UTF-8 displayed as CP1252.

On Windows, many editors assume the default ANSI encoding (CP1252 on US Windows) instead of UTF-8 if there is no byte order mark (BOM) character at the start of the file. While a BOM is meaningless to the UTF-8 encoding, its UTF-8-encoded presence serves as a signature for some programs. For example, Microsoft Office's Excel requires it even on non-Windows OSes. Try:

df.to_csv('file.csv',encoding='utf-8-sig')

That encoder will add the BOM.

public static String readFileToString(String filePath) {
    InputStream in = Test.class.getResourceAsStream(filePath);//filePath="/com/myproject/Sample.xml"
    try {
        return IOUtils.toString(in, StandardCharsets.UTF_8);
    } catch (IOException e) {
        logger.error("Failed to read the xml : ", e);
    }
    return null;
}

Change the img-class responsive to:

.img-responsive, x:-moz-any-link {
display: block;
max-width: 100%;
width: auto;
height: auto;

Euler path is a graph using every edge(NOTE) of the graph exactly once. Euler circuit is a euler path that returns to it starting point after covering all edges.

While hamilton path is a graph that covers all vertex(NOTE) exactly once. When this path returns to its starting point than this path is called hamilton circuit.

To get a count of the number of unique combinations of id, name and address:

SELECT Count(*)
FROM   (
        SELECT DISTINCT
               id
             , name
             , address
        FROM   your_table
       ) As distinctified

Yep! Use the link:

https://m.google.com/app/plus/x/?v=compose&content=YOUR_TEXT

It's SHARE url (not used for plus one) button.

If this will not work (not for me) try this url:

https://plusone.google.com/_/+1/confirm?hl=ru&url=_URL_&title=_TITLE_

Or see this solution:

Adding a Google Plus (one or share) link to an email newsletter

DECLARE @myList TABLE (Id BIGINT) INSERT INTO @myList(Id) VALUES (1),(2),(3),(4);
select * from myTable where myColumn in(select Id from @myList)

Please note that for long list or production systems it's not recommended to use this way as it may be much more slower than simple INoperator like someColumnName in (1,2,3,4) (tested using 8000+ items list)

Thanks acdcjunior for your solution. Here's a little optimized version for formatting and parsing :

public static final SimpleDateFormat XML_SDF = new SimpleDateFormat("yyyy-MM-dd'T'HH:mm:ssZ", Locale.FRANCE)
{
    private static final long serialVersionUID = -8275126788734707527L;

    public StringBuffer format(Date date, StringBuffer toAppendTo, java.text.FieldPosition pos)
    {            
        final StringBuffer buf = super.format(date, toAppendTo, pos);
        buf.insert(buf.length() - 2, ':');
        return buf;
    };

    public Date parse(String source) throws java.text.ParseException {
        final int split = source.length() - 2;
        return super.parse(source.substring(0, split - 1) + source.substring(split)); // replace ":" du TimeZone
    };
};

I'm trying to close users connection in version 1.0 and found this method:

socket.conn.close()

The difference between this method and disconnect() is that the client will keep trying to reconnect to the server.

Just had to write a "live" example at work :)

This one supports multiple values for UserId on the same date.

Columns: UserId, Value, Date

SELECT
   DISTINCT UserId,
   MAX(Date) OVER (PARTITION BY UserId ORDER BY Date DESC),
   MAX(Values) OVER (PARTITION BY UserId ORDER BY Date DESC)
FROM
(
   SELECT UserId, Date, SUM(Value) As Values
   FROM <<table_name>>
   GROUP BY UserId, Date
)

You can use FIRST_VALUE instead of MAX and look it up in the explain plan. I didn't have the time to play with it.

Of course, if searching through huge tables, it's probably better if you use FULL hints in your query.

int means interrupt, and the number 0x80 is the interrupt number. An interrupt transfers the program flow to whomever is handling that interrupt, which is interrupt 0x80 in this case. In Linux, 0x80 interrupt handler is the kernel, and is used to make system calls to the kernel by other programs.

The kernel is notified about which system call the program wants to make, by examining the value in the register %eax (AT&T syntax, and EAX in Intel syntax). Each system call have different requirements about the use of the other registers. For example, a value of 1 in %eax means a system call of exit(), and the value in %ebx holds the value of the status code for exit().

I just copied tools.jar file from JDK\lib folder to JRE\lib folder. Since then it worked like a champ.

found a solution, in my config file I just changed

$cfg['Servers'][$i]['auth_type'] = 'config';

to

$cfg['Servers'][$i]['auth_type'] = 'HTTP';

select year(current_timestamp)

SQLFiddle demo

I know this thread is really old but the solution from @Ivan Bondarenko helped me in my situation.

I had the following in my pom.xml.

<build>
    ...
    <plugins>
         <plugin>
                <groupId>com.consol.citrus</groupId>
                <artifactId>citrus-remote-maven-plugin</artifactId>
                <version>${citrus.version}</version>
                <executions>
                    <execution>
                        <id>generate-citrus-war</id>
                        <goals>
                            <goal>test-war</goal>
                        </goals>
                    </execution>
                </executions>
            </plugin>
    </plugins>
</build>

What I wanted, was to disable the execution of generate-citrus-war for a specific profile and this was the solution:

<profile>
    <id>it</id>
    <build>
        <plugins>
            <plugin>
                <groupId>com.consol.citrus</groupId>
                <artifactId>citrus-remote-maven-plugin</artifactId>
                <version>${citrus.version}</version>
                <executions>
                    <!-- disable generating the war for this profile -->
                    <execution>
                        <id>generate-citrus-war</id>
                        <phase/>
                    </execution>

                    <!-- do something else -->
                    <execution>
                        ...
                    </execution>
                </executions>
            </plugin>
        </plugins>
    </build>
</profile>

In Python 3 the dict.values() method returns a dictionary view object, not a list like it does in Python 2. Dictionary views have a length, can be iterated, and support membership testing, but don't support indexing.

To make your code work in both versions, you could use either of these:

{names[i]:value for i,value in enumerate(d.values())}

    or

values = list(d.values())
{name:values[i] for i,name in enumerate(names)}

By far the simplest, fastest way to do the same thing in either version would be:

dict(zip(names, d.values()))

Note however, that all of these methods will give you results that will vary depending on the actual contents of d. To overcome that, you may be able use an OrderedDict instead, which remembers the order that keys were first inserted into it, so you can count on the order of what is returned by the values() method.

You can use BackgroundScheduler() from APScheduler package (v3.5.3):

import time
import atexit

from apscheduler.schedulers.background import BackgroundScheduler


def print_date_time():
    print(time.strftime("%A, %d. %B %Y %I:%M:%S %p"))


scheduler = BackgroundScheduler()
scheduler.add_job(func=print_date_time, trigger="interval", seconds=3)
scheduler.start()

# Shut down the scheduler when exiting the app
atexit.register(lambda: scheduler.shutdown())

Note that two of these schedulers will be launched when Flask is in debug mode. For more information, check out this question.

I was also wondering how to store it cleanly in a variable. As using

char c = '•';

is not very good practice (I guess). I found out the following way of storing it in a variable

char c = (char)0x2022;// or 0x25cf depending on the one you choose

or even cleaner

char c = '\u2022';// or "\u25cf"

https://msdn.microsoft.com/en-us/library/aa664669%28v=vs.71%29.aspx

same for strings

string s = "\u2022";

https://msdn.microsoft.com/en-us/library/362314fe.aspx

I used the following:

delta = timedelta()
totalMinute, second = divmod(delta.seconds, 60)
hour, minute = divmod(totalMinute, 60)
print(f"{hour}h{minute:02}m{second:02}s")

I think you should use border-color instead of color, if your intention is to change the color of the line produced by <hr> tag.

Although, it has been pointed in comments that, if you change the size of your line, border will still be as wide as you specified in styles, and line will be filled with the default color (which is not a desired effect most of the time). So it seems like in this case you would also need to specify background-color (as @Ibu suggested in his answer).

HTML 5 Boilerplate project in its default stylesheet specifies the following rule:

hr { display: block; height: 1px;
    border: 0; border-top: 1px solid #ccc;
    margin: 1em 0; padding: 0; }

An article titled “12 Little-Known CSS Facts”, published recently by SitePoint, mentions that <hr> can set its border-color to its parent's color if you specify hr { border-color: inherit }.

java.util.MissingResourceException: Can't find bundle for base name
    org.jfree.chart.LocalizationBundle, locale en_US

To the point, the exception message tells in detail that you need to have either of the following files in the classpath:

/org/jfree/chart/LocalizationBundle.properties

or

/org/jfree/chart/LocalizationBundle_en.properties

or

/org/jfree/chart/LocalizationBundle_en_US.properties

Also see the official Java tutorial about resourcebundles for more information.

But as this is actually a 3rd party managed properties file, you shouldn't create one yourself. It should be already available in the JFreeChart JAR file. So ensure that you have it available in the classpath during runtime. Also ensure that you're using the right version, the location of the propertiesfile inside the package tree might have changed per JFreeChart version.

When executing a JAR file, you can use the -cp argument to specify the classpath. E.g.:

java -jar -cp c:/path/to/jfreechart.jar yourfile.jar

Alternatively you can specify the classpath as class-path entry in the JAR's manifest file. You can use in there relative paths which are relative to the JAR file itself. Do not use the %CLASSPATH% environment variable, it's ignored by JAR's and everything else which aren't executed with java.exe without -cp, -classpath and -jar arguments.

Modern Django have self template tag filesizeformat:

Formats the value like a human-readable file size (i.e. '13 KB', '4.1 MB', '102 bytes', etc.).

For example:

{{ value|filesizeformat }}

If value is 123456789, the output would be 117.7 MB.

More info: https://docs.djangoproject.com/en/1.10/ref/templates/builtins/#filesizeformat

It's quite clearly from their docs:

If you used componentWillReceiveProps for re-computing some data only when a prop changes, use a memoization helper instead.

Use: https://reactjs.org/blog/2018/06/07/you-probably-dont-need-derived-state.html#what-about-memoization

< stands for lesser than (<) symbol and, the > sign stands for greater than (>) symbol.

I see two problems:

The pointer answer is a null pointer and you are trying to dereference it in scanf, this leads to undefined behavior.

You don't need a char pointer here. You can just use a char variable as:

char answer;
scanf(" %c",&answer);

Next to see if the read character is 'y' or 'Y' you should do:

if( answer == 'y' || answer == 'Y') {
  // user entered y or Y.
}

If you really need to use a char pointer you can do something like:

char var;
char *answer = &var; // make answer point to char variable var.
scanf (" %c", answer);
if( *answer == 'y' || *answer == 'Y') {

for same height you should chage your css "display" Properties. For more detail see given example.

This isn't the direct answer to your question, but since you seem to just want to disassemble the binary, perhaps you could just use objdump:

objdump -d program

This should give you its dissassembly. You can add -S if you want it source-annotated.

according jdk source code from javasourcecode.org, HashSet use HashMap as its inside implementation, the code about put method of HashSet is below :

public V put(K key, V value) {
        if (key == null)
            return putForNullKey(value);
        int hash = hash(key.hashCode());
        int i = indexFor(hash, table.length);
        for (Entry<K,V> e = table[i]; e != null; e = e.next) {
            Object k;
            if (e.hash == hash && ((k = e.key) == key || key.equals(k))) {
                V oldValue = e.value;
                e.value = value;
                e.recordAccess(this);
                return oldValue;
            }
        }

        modCount++;
        addEntry(hash, key, value, i);
        return null;
    }

The rule is firstly check the hash, then check the reference and then call equals method of the object will be putted in.

In C/C++, we can do the following, as you mentioned

for(int k = 1; k <= c ; k++)
for(int k = 1; k <= c ; k +=2)

We know that here k starts with 1 and go till (predefined) c with step value 1 or 2 gradually. We can do this in Python by following,

for k in range(1,c+1):
for k in range(1,c+1,2):

Check this for more in depth.

function GetDir($dir) {
    if (is_dir($dir)) {
        if ($kami = opendir($dir)) {
            while ($file = readdir($kami)) {
                if ($file != '.' && $file != '..') {
                    if (is_dir($dir . $file)) {
                        echo $dir . $file;
                        // since it is a directory we recurse it.
                        GetDir($dir . $file . '/');
                    } else {
                        echo $dir . $file;
                    }
                }
            }
        }
        closedir($kami);
    }
}

Improved answer from @shamittomar above to get the meta tags (or the specified one from html source)

Can be improved further... the difference from php's default get_meta_tags is that it works even when there is unicode string

function getMetaTags($html, $name = null)
{
    $doc = new DOMDocument();
    try {
        @$doc->loadHTML($html);
    } catch (Exception $e) {

    }

    $metas = $doc->getElementsByTagName('meta');

    $data = [];
    for ($i = 0; $i < $metas->length; $i++)
    {
        $meta = $metas->item($i);

        if (!empty($meta->getAttribute('name'))) {
            // will ignore repeating meta tags !!
            $data[$meta->getAttribute('name')] = $meta->getAttribute('content');
        }
    }

    if (!empty($name)) {
        return !empty($data[$name]) ? $data[$name] : false;
    }

    return $data;
}

Specifically, to install the pdf.js plugin for firefox, you do not use the app store. Instead, go to addons.mozilla.org from inside mozilla and install it from there. Also, to see if it's installed properly, go to the menu Tools:Add-ons (not the "about:plugins" url as you might think from the desktop version).

(New account, otherwise I'd put this as a comment on the answer above)

Funny the answer is hidden in among the answers.

str.replace("•", "something") 

would work if you use the right semantics.

str.replace(u"\u2022","something") 

works wonders ;) , thnx to RParadox for the hint.

I use os.system

import os
os.system("pdftoppm -png {} {}".format(path2pdf, os.path.join(tmpdirname, "temp")))

It is very simple just look at their names @RequestParam it consist of two parts one is "Request" which means it is going to deal with request and other part is "Param" which itself makes sense it is going to map only the parameters of requests to java objects. Same is the case with @RequestBody it is going to deal with the data that has been arrived with request like if client has send json object or xml with request at that time @requestbody must be used.

Required ghostscript & tiffcp Tested in Ubuntu

import os

def pdf2tiff(source, destination):
    idx = destination.rindex('.')
    destination = destination[:idx]
    args = [
    '-q', '-dNOPAUSE', '-dBATCH',
    '-sDEVICE=tiffg4',
    '-r600', '-sPAPERSIZE=a4',
    '-sOutputFile=' + destination + '__%03d.tiff'
    ]
    gs_cmd = 'gs ' + ' '.join(args) +' '+ source
    os.system(gs_cmd)
    args = [destination + '__*.tiff', destination + '.tiff' ]
    tiffcp_cmd = 'tiffcp  ' + ' '.join(args)
    os.system(tiffcp_cmd)
    args = [destination + '__*.tiff']
    rm_cmd = 'rm  ' + ' '.join(args)
    os.system(rm_cmd)    
pdf2tiff('abc.pdf', 'abc.tiff')

You can set your content-type header so clients know to expect json

w.Header().Set("Content-Type", "application/json")

Another way to marshal a struct to json is to build an encoder using the http.ResponseWriter

// get a payload p := Payload{d}
json.NewEncoder(w).Encode(p)

Try c.ToString("F6");

If you want to use parameters for a,b,c,d in Laravel 4

Model::where(function ($query) use ($a,$b) {
    $query->where('a', '=', $a)
          ->orWhere('b', '=', $b);
})
->where(function ($query) use ($c,$d) {
    $query->where('c', '=', $c)
          ->orWhere('d', '=', $d);
});

Use:

$date = date('m/d/Y h:i:s a', time());

It works.

public static Bitmap resizeBitmapByScale(
            Bitmap bitmap, float scale, boolean recycle) {
        int width = Math.round(bitmap.getWidth() * scale);
        int height = Math.round(bitmap.getHeight() * scale);
        if (width == bitmap.getWidth()
                && height == bitmap.getHeight()) return bitmap;
        Bitmap target = Bitmap.createBitmap(width, height, getConfig(bitmap));
        Canvas canvas = new Canvas(target);
        canvas.scale(scale, scale);
        Paint paint = new Paint(Paint.FILTER_BITMAP_FLAG | Paint.DITHER_FLAG);
        canvas.drawBitmap(bitmap, 0, 0, paint);
        if (recycle) bitmap.recycle();
        return target;
    }
    private static Bitmap.Config getConfig(Bitmap bitmap) {
        Bitmap.Config config = bitmap.getConfig();
        if (config == null) {
            config = Bitmap.Config.ARGB_8888;
        }
        return config;
    }

It seems that Google has updated its developer page and added various trainings there.

One of them deals with the creation of custom views and can be found here

Command:

netstat -aon | findstr 4723

Output:

TCP    0.0.0.0:4723           0.0.0.0:0                LISTENING       10396

Now cut the process ID, "10396", using the for command in Windows.

Command:

for /f "tokens=5" %a in ('netstat -aon ^| findstr 4723') do @echo %~nxa

Output:

10396

If you want to cut the 4th number of the value means "LISTENING" then command in Windows.

Command:

for /f "tokens=4" %a in ('netstat -aon ^| findstr 4723') do @echo %~nxa

Output:

LISTENING

this is possible with jQuery $.ajax() method

$.ajax(serverUrl, {
   type: OutageViewModel.Id() == 0 ? "POST" : "PUT",
   data: dataToSave,
   statusCode: {
      200: function (response) {
         alert('1');
         AfterSavedAll();
      },
      201: function (response) {
         alert('1');
         AfterSavedAll();
      },
      400: function (response) {
         alert('1');
         bootbox.alert('<span style="color:Red;">Error While Saving Outage Entry Please Check</span>', function () { });
      },
      404: function (response) {
         alert('1');
         bootbox.alert('<span style="color:Red;">Error While Saving Outage Entry Please Check</span>', function () { });
      }
   }, success: function () {
      alert('1');
   },
});

Perhaps something like this for the first problem, you can simply access the columns by their names:

>>> df = pd.DataFrame(np.random.rand(4,5), columns = list('abcde'))
>>> df[df['c']>.5][['b','e']]
          b         e
1  0.071146  0.132145
2  0.495152  0.420219

For the second problem:

>>> df[df['c']>.5][['b','e']].values
array([[ 0.07114556,  0.13214495],
       [ 0.49515157,  0.42021946]])

Code to add audio to video using ffmpeg.

If audio length is greater than video length it will cut the audio to video length. If you want full audio in video remove -shortest from the cmd.

String[] cmd = new String[]{"-i", selectedVideoPath,"-i",audiopath,"-map","1:a","-map","0:v","-codec","copy", ,outputFile.getPath()};

private void execFFmpegBinaryShortest(final String[] command) {



            final File outputFile = new File(Environment.getExternalStorageDirectory().getAbsolutePath()+"/videoaudiomerger/"+"Vid"+"output"+i1+".mp4");




            String[] cmd = new String[]{"-i", selectedVideoPath,"-i",audiopath,"-map","1:a","-map","0:v","-codec","copy","-shortest",outputFile.getPath()};


            try {

                ffmpeg.execute(cmd, new ExecuteBinaryResponseHandler() {
                    @Override
                    public void onFailure(String s) {
                        System.out.println("on failure----"+s);
                    }

                    @Override
                    public void onSuccess(String s) {
                        System.out.println("on success-----"+s);
                    }

                    @Override
                    public void onProgress(String s) {
                        //Log.d(TAG, "Started command : ffmpeg "+command);
                        System.out.println("Started---"+s);

                    }

                    @Override
                    public void onStart() {


                        //Log.d(TAG, "Started command : ffmpeg " + command);
                        System.out.println("Start----");

                    }

                    @Override
                    public void onFinish() {
                        System.out.println("Finish-----");


                    }
                });
            } catch (FFmpegCommandAlreadyRunningException e) {
                // do nothing for now
                System.out.println("exceptio :::"+e.getMessage());
            }


        }

I post an answer because I can't comment but I followed @DrCJones steps. I installed the new Crystal Reports SP21 for Visual Studio 2017 with an older version running on my Windows 10. Installer warned me that it detected an older version and that it will overwrite it. Installation were through but I had the following message when I tried to open a project with reports in VS2017:

The Crystal Reports Tools Package did not load correctly

I couldn't edit reports either. So, I manually uninstalled CR Runtime Engine & CR for VS, then reinstalled SP21, finally rebooted.

Now it works :)

have all the pages in distinct div areas

<div style="" id="page1">
First Page Contents
</div>

<div style="display:none" id="page2">
Second Page Contents
</div>

then use a js script to workout what you are viewing (like within an hashtag style) to navigate. Either that, or ajax to get the response from a specific file (like /pages/page1.html)

var $prehashval = "";
function loop()
{
    if (location.hash.slice(1)!=$prehashval)
        hashChanged();

    $prehashval = location.hash.slice(1);
    setTimeout("loop()", 100);
}
function hashChanged()
{
    var $output;
    switch (location.hash.slice(1))
    {
        case "page1":
            document.getElementById('page1').style.display = "";
            document.getElementById('page2').style.display = "none";
            break;
        case "page2":
            document.getElementById('page1').style.display = "none";
            document.getElementById('page2').style.display = "";
            break;
        default:
            $output = location.hash.slice(1);
    }
}
loop();

you can use :

git remote remove origin

to remove a linked repo then:

git remote add origin

to add new one

More of an addendum. I did repro the experiment using the latest Java 8 JVM from IBM:

java version "1.8.0_191"
Java(TM) 2 Runtime Environment, Standard Edition (IBM build 1.8.0_191-b12 26_Oct_2018_18_45 Mac OS X x64(SR5 FP25))
Java HotSpot(TM) 64-Bit Server VM (build 25.191-b12, mixed mode)

And this shows very similar results:

0.374653912 s
n = 119860736
0.447778698 s
n = 119860736

(second results using 2 * i * i).

Interestingly enough, when running on the same machine, but using Oracle Java:

Java version "1.8.0_181"
Java(TM) SE Runtime Environment (build 1.8.0_181-b13)
Java HotSpot(TM) 64-Bit Server VM (build 25.181-b13, mixed mode)

results are on average a bit slower:

0.414331815 s
n = 119860736
0.491430656 s
n = 119860736

Long story short: even the minor version number of HotSpot matter here, as subtle differences within the JIT implementation can have notable effects.

I think that what you want to do is turn the JSON string back into an object when it arrives back in your XMLHttpRequest - correct?

If so, you need to eval the string to turn it into a JavaScript object - note that this can be unsafe as you're trusting that the JSON string isn't malicious and therefore executing it. Preferably you could use jQuery's parseJSON

Delete /var/lib/mongodb/mongod.lock, then issue sudo service mongodb start, then mongo.

You have to change

<style name="MyActionBar.MenuTextStyle"
parent="android:style/TextAppearance.Holo.Widget.ActionBar.Title">

to

<style name="MyActionBar.MenuTextStyle"
parent="android:style/TextAppearance.Holo.Widget.ActionBar.Menu">

as well. This works for me.

I usually shy away from queries from sys* type tables, vendors tend to change these between releases, major or otherwise. What I have always done is to issue the DROP FUNCTION <name> statement and not worry about any SQL error that might come back. I consider that standard procedure in the DBA realm.

Seems related to https://groups.google.com/forum/#!msg/google-caja-discuss/ite6K5c8mqs/Ayqw72XJ9G8J.

The so-called "Rosetta Flash" vulnerability is that allowing arbitrary yet identifier-like text at the beginning of a JSONP response is sufficient for it to be interpreted as a Flash file executing in that origin. See for more information: http://miki.it/blog/2014/7/8/abusing-jsonp-with-rosetta-flash/

JSONP responses from the proxy servlet now: * are prefixed with "/**/", which still allows them to execute as JSONP but removes requester control over the first bytes of the response. * have the response header Content-Disposition: attachment.

!== should match the value and data type

!= just match the value ignoring the data type

$num = '1';
$num2 = 1;

$num == $num2; // returns true    
$num === $num2; // returns false because $num is a string and $num2 is an integer

The standard does say this:

Programming languages vary widely on whether they support objects, and if so, what characteristics and constraints the objects offer. The models of object systems can be wildly divergent and are continuing to evolve. JSON instead provides a simple notation for expressing collections of name/value pairs. Most programming languages will have some feature for representing such collections, which can go by names like record, struct, dict, map, hash, or object.

The bug is in node.js at least. This code succeeds in node.js.

try {
     var json = {"name":"n","name":"v"};
     console.log(json); // outputs { name: 'v' }
} catch (e) {
     console.log(e);
}

You can use finishAndRemoveTask () from API 21

public void finishAndRemoveTask ()

Finishes all activities in this task and removes it from the recent tasks list.

You certainly are able to have multiple CTEs in a single query expression. You just need to separate them with a comma. Here is an example. In the example below, there are two CTEs. One is named CategoryAndNumberOfProducts and the second is named ProductsOverTenDollars.

WITH CategoryAndNumberOfProducts (CategoryID, CategoryName, NumberOfProducts) AS
(
   SELECT
      CategoryID,
      CategoryName,
      (SELECT COUNT(1) FROM Products p
       WHERE p.CategoryID = c.CategoryID) as NumberOfProducts
   FROM Categories c
),

ProductsOverTenDollars (ProductID, CategoryID, ProductName, UnitPrice) AS
(
   SELECT
      ProductID,
      CategoryID,
      ProductName,
      UnitPrice
   FROM Products p
   WHERE UnitPrice > 10.0
)

SELECT c.CategoryName, c.NumberOfProducts,
      p.ProductName, p.UnitPrice
FROM ProductsOverTenDollars p
   INNER JOIN CategoryAndNumberOfProducts c ON
      p.CategoryID = c.CategoryID
ORDER BY ProductName

Method 1 : Using jQuery Ajax Get call (partial page update).

Suitable for when you need to retrieve jSon data from database.

Controller's Action Method

[HttpGet]
public ActionResult Foo(string id)
{
    var person = Something.GetPersonByID(id);
    return Json(person, JsonRequestBehavior.AllowGet);
}

Jquery GET

function getPerson(id) {
    $.ajax({
        url: '@Url.Action("Foo", "SomeController")',
        type: 'GET',
        dataType: 'json',
        // we set cache: false because GET requests are often cached by browsers
        // IE is particularly aggressive in that respect
        cache: false,
        data: { id: id },
        success: function(person) {
            $('#FirstName').val(person.FirstName);
            $('#LastName').val(person.LastName);
        }
    });
}

Person class

public class Person
{
    public string FirstName { get; set; }
    public string LastName { get; set; }
}

Method 2 : Using jQuery Ajax Post call (partial page update).

Suitable for when you need to do partial page post data into database.

Post method is also same like above just replace [HttpPost] on Action method and type as post for jquery method.

For more information check Posting JSON Data to MVC Controllers Here

Method 3 : As a Form post scenario (full page update).

Suitable for when you need to save or update data into database.

View

@using (Html.BeginForm("SaveData","ControllerName", FormMethod.Post))
{        
    @Html.TextBoxFor(model => m.Text)
    
    <input type="submit" value="Save" />
}

Action Method

[HttpPost]
public ActionResult SaveData(FormCollection form)
    {
        // Get movie to update
        return View();
   }

Method 4 : As a Form Get scenario (full page update).

Suitable for when you need to Get data from database

Get method also same like above just replace [HttpGet] on Action method and FormMethod.Get for View's form method.

I hope this will help to you.

You can do it using javascript

• Change iframe background color
• Change background color of the loaded page (same domain)

Plain javascript

var iframe = document.getElementsByTagName('iframe')[0];
iframe.style.background = 'white';
iframe.contentWindow.document.body.style.backgroundColor = 'white';

jQuery

$('iframe').css('background', 'white');
$('iframe').contents().find('body').css('backgroundColor', 'white');

Here's a simple Kalman filter that could be used for exactly this situation. It came from some work I did on Android devices.

General Kalman filter theory is all about estimates for vectors, with the accuracy of the estimates represented by covariance matrices. However, for estimating location on Android devices the general theory reduces to a very simple case. Android location providers give the location as a latitude and longitude, together with an accuracy which is specified as a single number measured in metres. This means that instead of a covariance matrix, the accuracy in the Kalman filter can be measured by a single number, even though the location in the Kalman filter is a measured by two numbers. Also the fact that the latitude, longitude and metres are effectively all different units can be ignored, because if you put scaling factors into the Kalman filter to convert them all into the same units, then those scaling factors end up cancelling out when converting the results back into the original units.

The code could be improved, because it assumes that the best estimate of current location is the last known location, and if someone is moving it should be possible to use Android's sensors to produce a better estimate. The code has a single free parameter Q, expressed in metres per second, which describes how quickly the accuracy decays in the absence of any new location estimates. A higher Q parameter means that the accuracy decays faster. Kalman filters generally work better when the accuracy decays a bit quicker than one might expect, so for walking around with an Android phone I find that Q=3 metres per second works fine, even though I generally walk slower than that. But if travelling in a fast car a much larger number should obviously be used.

public class KalmanLatLong {
    private final float MinAccuracy = 1;

    private float Q_metres_per_second;    
    private long TimeStamp_milliseconds;
    private double lat;
    private double lng;
    private float variance; // P matrix.  Negative means object uninitialised.  NB: units irrelevant, as long as same units used throughout

    public KalmanLatLong(float Q_metres_per_second) { this.Q_metres_per_second = Q_metres_per_second; variance = -1; }

    public long get_TimeStamp() { return TimeStamp_milliseconds; }
    public double get_lat() { return lat; }
    public double get_lng() { return lng; }
    public float get_accuracy() { return (float)Math.sqrt(variance); }

    public void SetState(double lat, double lng, float accuracy, long TimeStamp_milliseconds) {
        this.lat=lat; this.lng=lng; variance = accuracy * accuracy; this.TimeStamp_milliseconds=TimeStamp_milliseconds;
    }

    public void Process(double lat_measurement, double lng_measurement, float accuracy, long TimeStamp_milliseconds) {
        if (accuracy < MinAccuracy) accuracy = MinAccuracy;
        if (variance < 0) {
            // if variance < 0, object is unitialised, so initialise with current values
            this.TimeStamp_milliseconds = TimeStamp_milliseconds;
            lat=lat_measurement; lng = lng_measurement; variance = accuracy*accuracy; 
        } else {
            // else apply Kalman filter methodology

            long TimeInc_milliseconds = TimeStamp_milliseconds - this.TimeStamp_milliseconds;
            if (TimeInc_milliseconds > 0) {
                // time has moved on, so the uncertainty in the current position increases
                variance += TimeInc_milliseconds * Q_metres_per_second * Q_metres_per_second / 1000;
                this.TimeStamp_milliseconds = TimeStamp_milliseconds;
                // TO DO: USE VELOCITY INFORMATION HERE TO GET A BETTER ESTIMATE OF CURRENT POSITION
            }

            // Kalman gain matrix K = Covarariance * Inverse(Covariance + MeasurementVariance)
            // NB: because K is dimensionless, it doesn't matter that variance has different units to lat and lng
            float K = variance / (variance + accuracy * accuracy);
            // apply K
            lat += K * (lat_measurement - lat);
            lng += K * (lng_measurement - lng);
            // new Covarariance  matrix is (IdentityMatrix - K) * Covarariance 
            variance = (1 - K) * variance;
        }
    }
}

If you use as following, your code can be more effective than you wrote. You should add another feature.

.abc, .xyz {
margin-left:20px;
width: 100px;
height: 100px;
} 

OR

a.abc, a.xyz {
margin-left:20px;
width: 100px;
height: 100px;
} 

OR

a {
margin-left:20px;
width: 100px;
height: 100px;
} 

Do you need to look up objects by the key? If not, consider using List<Tuple<string, string>> or List<KeyValuePair<string, string>> if you're not using .NET 4.

referring to radio buttons ,you can also do it with Segmented Control as following:

step 1: drag a segmented control to your view in the attribute inspector change the title of the two segments ,for example "Male" and "Female"

step 2: create an outlet & an action for it in the code

step 3: create a variable for future use to contain choice's data

in the code do as following:

@IBOutlet weak var genderSeg: UISegmentedControl!

var genderPick : String = ""


 @IBAction func segAction(_ sender: Any) {

    if genderSeg.selectedSegmentIndex == 0 {
         genderPick = "Male"
        print(genderPick)
    } else if genderSeg.selectedSegmentIndex == 1 {
        genderPick = "Female"
          print(genderPick)
    }
}

As nextXXX() methods don't read newline, except nextLine(). We can skip the newline after reading any non-string value (int in this case) by using scanner.skip() as below:

Scanner sc = new Scanner(System.in);
int x = sc.nextInt();
sc.skip("(\r\n|[\n\r\u2028\u2029\u0085])?");
System.out.println(x);
double y = sc.nextDouble();
sc.skip("(\r\n|[\n\r\u2028\u2029\u0085])?");
System.out.println(y);
char z = sc.next().charAt(0);
sc.skip("(\r\n|[\n\r\u2028\u2029\u0085])?");
System.out.println(z);
String hello = sc.nextLine();
System.out.println(hello);
float tt = sc.nextFloat();
sc.skip("(\r\n|[\n\r\u2028\u2029\u0085])?");
System.out.println(tt);

What if you do this (as was suggested earlier):

new_time = dfs['XYF']['TimeUS'].astype(float)
new_time_F = new_time / 1000000

This is because of a higher JDK during compile time and lower JDK during runtime. So you just need to update your JDK version, possible to JDK 7

Here is another way to loop through XML elements using JDOM.

        List<Element> nodeNodes = inputNode.getChildren();
        if (nodeNodes != null) {
            for (Element nodeNode : nodeNodes) {
                List<Element> elements = nodeNode.getChildren(elementName);
                if (elements != null) {
                    elements.size();
                    nodeNodes.removeAll(elements);
                }
            }

In addition to the solution you accepted, you could also implement the special __lt__() ("less than") method on the class. The sort() method (and the sorted() function) will then be able to compare the objects, and thereby sort them. This works best when you will only ever sort them on this attribute, however.

class Foo(object):

     def __init__(self, score):
         self.score = score

     def __lt__(self, other):
         return self.score < other.score

l = [Foo(3), Foo(1), Foo(2)]
l.sort()

The R class is written when you build the project in gradle. You should add the raw folder, then build the project. After that, the R class will be able to identify R.raw.*.

You copied using Cells.
If so, no need to PasteSpecial since you are copying data at exactly the same format.
Here's your code with some fixes.

Dim x As Workbook, y As Workbook
Dim ws1 As Worksheet, ws2 As Worksheet

Set x = Workbooks.Open("path to copying book")
Set y = Workbooks.Open("path to pasting book")

Set ws1 = x.Sheets("Sheet you want to copy from")
Set ws2 = y.Sheets("Sheet you want to copy to")

ws1.Cells.Copy ws2.cells
y.Close True
x.Close False

If however you really want to paste special, use a dynamic Range("Address") to copy from.
Like this:

ws1.Range("Address").Copy: ws2.Range("A1").PasteSpecial xlPasteValues
y.Close True
x.Close False

Take note of the : colon after the .Copy which is a Statement Separating character.
Using Object.PasteSpecial requires to be executed in a new line.
Hope this gets you going.

The Visual Studio Build tools are a different download than the IDE. They appear to be a pretty small subset, and they're called Build Tools for Visual Studio 2019 (download).

You can use the GUI to do the installation, or you can script the installation of msbuild:

vs_buildtools.exe --add Microsoft.VisualStudio.Workload.MSBuildTools --quiet

Microsoft.VisualStudio.Workload.MSBuildTools is a "wrapper" ID for the three subcomponents you need:

• Microsoft.Component.MSBuild
• Microsoft.VisualStudio.Component.CoreBuildTools
• Microsoft.VisualStudio.Component.Roslyn.Compiler

You can find documentation about the other available CLI switches here.

The build tools installation is much quicker than the full IDE. In my test, it took 5-10 seconds. With --quiet there is no progress indicator other than a brief cursor change. If the installation was successful, you should be able to see the build tools in %programfiles(x86)%\Microsoft Visual Studio\2019\BuildTools\MSBuild\Current\Bin.

If you don't see them there, try running without --quiet to see any error messages that may occur during installation.

It's been many functions, macros and objects since I posted this question. The way I handled it, which is mentioned in one of the answers here, is by creating a string function that handles the errors that get generate by the vlookup function, and returns either nothing or the vlookup result if any.

Function fsVlookup(ByVal pSearch As Range, ByVal pMatrix As Range, ByVal pMatColNum As Integer) As String
    Dim s As String
    On Error Resume Next
    s = Application.WorksheetFunction.VLookup(pSearch, pMatrix, pMatColNum, False)
    If IsError(s) Then
        fsVlookup = ""
    Else
        fsVlookup = s
    End If
End Function

One could argue about the position of the error handling or by shortening this code, but it works in all cases for me, and as they say, "if it ain't broke, don't try and fix it".

I'm not entirely sure but I think you are probably surprised at how arrays are serialized in JSON. Let's isolate the problem. Consider following code:

var display = Array();
display[0] = "none";
display[1] = "block";
display[2] = "none";

console.log( JSON.stringify(display) );

This will print:

["none","block","none"]

This is how JSON actually serializes array. However what you want to see is something like:

{"0":"none","1":"block","2":"none"}

To get this format you want to serialize object, not array. So let's rewrite above code like this:

var display2 = {};
display2["0"] = "none";
display2["1"] = "block";
display2["2"] = "none";

console.log( JSON.stringify(display2) );

This will print in the format you want.

You can play around with this here: http://jsbin.com/oDuhINAG/1/edit?js,console

I found this working fine and useful to create a List from a Set.

ArrayList < String > L1 = new ArrayList < String > ();
L1.addAll(ActualMap.keySet());
for (String x: L1) {
    System.out.println(x.toString());
}

This could be due to many reasons; below are few of those:

1. If you are using complex data contract objects(that means custom object with more child custom objects), make sure you have all the custom objects decorated with DataContract and DataMember attributes

2. If your data contract objects use inheritance, make sure all base classes has the DataContract and DataMember attributes. Also, you need to have the base classes specify the derived classes with the [KnownType(typeof(BaseClassType))] attribute ( check out more info here on this).

3. Make sure all your data contract object properties have both get and set properties.

First of all, You can verify this on your own by writing a simple TestCase!

empty Arraylist (with nulls as its items)

Second, If ArrayList is EMPTY that means it is really empty, it cannot have NULL or NON-NULL things as element.

Third,

 List list  = new ArrayList();
    list.add(null);
    System.out.println(list == null)

would print false.

Once you have established that they don't match, you still have a problem -- what to do about it. Often, the certificate may merely be assembled incorrectly. When a CA signs your certificate, they send you a block that looks something like

-----BEGIN CERTIFICATE-----
MIIAA-and-a-buncha-nonsense-that-is-your-certificate
-and-a-buncha-nonsense-that-is-your-certificate-and-
a-buncha-nonsense-that-is-your-certificate-and-a-bun
cha-nonsense-that-is-your-certificate-and-a-buncha-n
onsense-that-is-your-certificate-AA+
-----END CERTIFICATE-----

they'll also send you a bundle (often two certificates) that represent their authority to grant you a certificate. this will look something like

-----BEGIN CERTIFICATE-----
MIICC-this-is-the-certificate-that-signed-your-request
-this-is-the-certificate-that-signed-your-request-this
-is-the-certificate-that-signed-your-request-this-is-t
he-certificate-that-signed-your-request-this-is-the-ce
rtificate-that-signed-your-request-A
-----END CERTIFICATE-----
-----BEGIN CERTIFICATE-----
MIICC-this-is-the-certificate-that-signed-for-that-one
-this-is-the-certificate-that-signed-for-that-one-this
-is-the-certificate-that-signed-for-that-one-this-is-t
he-certificate-that-signed-for-that-one-this-is-the-ce
rtificate-that-signed-for-that-one-this-is-the-certifi
cate-that-signed-for-that-one-AA
-----END CERTIFICATE-----

except that unfortunately, they won't be so clearly labeled.

a common practice, then, is to bundle these all up into one file -- your certificate, then the signing certificates. But since they aren't easily distinguished, it sometimes happens that someone accidentally puts them in the other order -- signing certs, then the final cert -- without noticing. In that case, your cert will not match your key.

You can test to see what the cert thinks it represents by running

openssl x509 -noout -text -in yourcert.cert

Near the top, you should see "Subject:" and then stuff that looks like your data. If instead it lookslike your CA, your bundle is probably in the wrong order; you might try making a backup, and then moving the last cert to the beginning, hoping that is the one that is your cert.

If this doesn't work, you might just have to get the cert re-issued. When I make a CSR, I like to clearly label what server it's for (instead of just ssl.key or server.key) and make a copy of it with the date in the name, like mydomain.20150306.key etc. that way they private and public key pairs are unlikely to get mixed up with another set.
