Turns out that the post (or rather the whole table) was locked by the very same connection that I tried to update the post with.

I had a opened record set of the post that was created by:

Set RecSet = Conn.Execute()

This type of recordset is supposed to be read-only and when I was using MS Access as database it did not lock anything. But apparently this type of record set did lock something on MS SQL Server 2012 because when I added these lines of code before executing the UPDATE SQL statement...

RecSet.Close
Set RecSet = Nothing

...everything worked just fine.

So bottom line is to be careful with opened record sets - even if they are read-only they could lock your table from updates.

Just specifying HTTPS in the URI should do the trick.

httpClient.BaseAddress = new Uri("https://foobar.com/");

If the request works with HTTP but fails with HTTPS then this is most certainly a certificate issue. Make sure the caller trusts the certificate issuer and that the certificate is not expired. A quick and easy way to check that is to try making the query in a browser.

You also may want to check on the server (if it's yours and / or if you can) that it is set to serve HTTPS requests properly.

Yes there is! After a lot of headache i found one solution to this.

Monitor.php

This php file will be monitoring the browser close event. Once the browser is closed the connection_aborted will return 1 hence the loop will break.

<?php
// Ignore user aborts and allow the script
// to run forever
ignore_user_abort(true);
set_time_limit(0);

echo connection_aborted();
while(1)
{
echo "Whatever you echo here wont be printed anywhere but it is required in order to work.";
flush();
if(connection_aborted())
{
break;
// Breaks only when browser is closed
}
}

/*
Action you want to take after browser is closed.
Write your code here
*/
?>

Caller.php

This is the file which will call Monitor.php

<?php
Header('Location: monitor.php');
?>

Parent.html

This will be the file which you will actually interact with. On loading this will directly make an AJAX call to Caller.php which will automatically start Monitor.php in background mode.

<script>

 var xmlhttp = new XMLHttpRequest();
        xmlhttp.onreadystatechange = function() {
            if (xmlhttp.readyState == 4 && xmlhttp.status == 200) {

            }
         }

   xmlhttp.open("GET", "Caller.php", true);
        xmlhttp.send();   

</script>

So the final flow is Parent.html----->Caller.php----->Monitor.php

I had to use Debug.print instead of Print, which works in the Immediate window.

Run this command after opening cmd as administrator

net start mssqlserver /T902

This command is called trace flag 902. It is used to bypass script upgrade mode. Every time when you try to start your sql service it also looks for script upgrades. and when the script upgrade fail your service unable to start. So, Whenever we have such upgrade script failure issue and SQL is not getting started, we need to use trace flag 902 to start SQL.

I hope this will help you..

Forcing the TCP/IP connection (by providing 127.0.0.1 instead of localhost or .) can reveal the real reason for the error. In my case, the database name specified in connection string was incorrect.

So, here is the checklist so far:

• Make sure Named Pipe is enabled in configuration manager (don't forget to restart the server).
• Make sure SQL Server Authentication (or Mixed Mode) is enabled.
• Make sure your user name and password are correct.
• Make sure the database you are connecting to exists.

For me, the following hack worked; Go to IIS -> Application Pools -> Advance Settings -> Process Model -> Identity Changed from Built-in Account (ApplicationPoolIdentity) to Custom Account (My Domain User)

Because, on whatever line the error is occurring at (you didn't tell us which that is), you're passing something to foreach that is not an array.

Look at what you're passing into foreach, determine what it is (with var_export), find out why it's not an array... and fix it.

Basic, basic debugging.

Use display instead of visibility. display: none for invisible and no setting for visible.

I've been verifying calls in the same manner - I believe it is the right way to do it.

mockSomething.Verify(ms => ms.Method(
    It.IsAny<int>(), 
    It.Is<MyObject>(mo => mo.Id == 5 && mo.description == "test")
  ), Times.Once());

If your lambda expression becomes unwieldy, you could create a function that takes MyObject as input and outputs true/false...

mockSomething.Verify(ms => ms.Method(
    It.IsAny<int>(), 
    It.Is<MyObject>(mo => MyObjectFunc(mo))
  ), Times.Once());

private bool MyObjectFunc(MyObject myObject)
{
  return myObject.Id == 5 && myObject.description == "test";
}

Also, be aware of a bug with Mock where the error message states that the method was called multiple times when it wasn't called at all. They might have fixed it by now - but if you see that message you might consider verifying that the method was actually called.

EDIT: Here is an example of calling verify multiple times for those scenarios where you want to verify that you call a function for each object in a list (for example).

foreach (var item in myList)
  mockRepository.Verify(mr => mr.Update(
    It.Is<MyObject>(i => i.Id == item.Id && i.LastUpdated == item.LastUpdated),
    Times.Once());

Same approach for setup...

foreach (var item in myList) {
  var stuff = ... // some result specific to the item
  this.mockRepository
    .Setup(mr => mr.GetStuff(item.itemId))
    .Returns(stuff);
}

So each time GetStuff is called for that itemId, it will return stuff specific to that item. Alternatively, you could use a function that takes itemId as input and returns stuff.

this.mockRepository
    .Setup(mr => mr.GetStuff(It.IsAny<int>()))
    .Returns((int id) => SomeFunctionThatReturnsStuff(id));

One other method I saw on a blog some time back (Phil Haack perhaps?) had setup returning from some kind of dequeue object - each time the function was called it would pull an item from a queue.

To disable inputting password:

sudo visudo

Then add a new line like below and save then:

# The user can run installer as root without inputting password
yourusername ALL=(root) NOPASSWD: /usr/sbin/installer

Then you run installer without password:

sudo installer -pkg ...

This error can also happen if the server only sends its leaf certificate and does not send all the chain certificates needed to build the trust chain to the root CA. Unfortunately this is a common misconfiguration of servers.

Most browsers work around this problem if they already know the missing chain certificate from earlier visits or maybe download the missing certificate if the leaf certificate contains a URL for CA issuers in Authority Information Access (AIA). But this behavior is usually restricted to desktop browsers and other tools simply fail because they cannot build the trust chain.

You can make the JRE to automatically download the intermediate certificate by setting com.sun.security.enableAIAcaIssuers to true

To verify if the server is sending all the chain certificates you can enter the host in the following SSL certificate validation tool https://www.digicert.com/help/

I too had this kind of headache. Got rid of of it by simply representing time fields as primitive long in my POJO. Now the generation of my WS client code handle everything correctly and no more XML-to-Java crap. And of course dealing with millis on the Java side is simple and painless. KISS principle rocks!

If you are willing to use Three20 framework, it has a category on NSString that adds stringByRemovingHTMLTags method. See NSStringAdditions.h in Three20Core subproject.

Building on this comment I wrote a one-liner to hit the Github Markdown API using curl and jq.

Paste this bash function onto the command line or into your ~/.bash_profile:

mdsee(){ 
    HTMLFILE="$(mktemp -u).html"
    cat "$1" | \
      jq --slurp --raw-input '{"text": "\(.)", "mode": "markdown"}' | \
      curl -s --data @- https://api.github.com/markdown > "$HTMLFILE"
    echo $HTMLFILE
    open "$HTMLFILE"
}

And then to see the rendered HTML in-browser run:

mdsee readme.md

Replace open "$HTMLFILE" with lynx "$HTMLFILE" if you need a pure terminal solution.

If you have used extern for functions before, exactly same philosophy is followed for templates. if not, going though extern for simple functions may help. Also, you may want to put the extern(s) in header file and include the header when you need it.

Determine what the User Agent is for the devices that you need to simulate and then test a variable against that.

for example:

// var userAgent = navigator.userAgent.toLowerCase(); // this would actually get the user agent

var userAgent = "iphone"; /* Simulates User Agent for iPhone */
if (userAgent.indexOf('iphone') != -1) {
   // some code here
}

I'm not sure there's a clear-cut definition of "framework". Sometimes a large set of libraries is called a framework, but I think the typical use of the word is closer to the definition aioobe brought.

This very nice article sums up the difference between just a set of libraries and a framework:

A framework can be defined as a set of libraries that say “Don’t call us, we’ll call you.”

How does a framework help you? Because instead of writing something from scratch, you basically just extend a given, working application. You get a lot of productivity this way - sometimes the resulting application can be far more elaborate than you could have done on your own in the same time frame - but you usually trade in a lot of flexibility.

The Gnumeric spreadsheet application comes with a command line utility called ssconvert that can convert between a variety of spreadsheet formats:

To install on Mac:

brew install gnumeric

"_blank" is not guaranteed to be a new tab or window. It's implemented differently per-browser.

You can, however, put anything into target. I usually just say "_tab", and every browser I know of just opens it in a new tab.

Be aware that it means it's a named target, so if you try to open 2 URLs, they will use the same tab.

I use this with good results:

border-style:hidden;

It also works for:

border-right-style:hidden; /*if you want to hide just a border on a cell*/

Example:

<style type="text/css">_x000D_
      table, th, td {_x000D_
       border: 2px solid green;_x000D_
      }_x000D_
      tr.hide_right > td, td.hide_right{_x000D_
        border-right-style:hidden;_x000D_
      }_x000D_
      tr.hide_all > td, td.hide_all{_x000D_
        border-style:hidden;_x000D_
      }_x000D_
  }_x000D_
</style>_x000D_
<table>_x000D_
  <tr>_x000D_
    <td class="hide_right">11</td>_x000D_
    <td>12</td>_x000D_
    <td class="hide_all">13</td>_x000D_
  </tr>_x000D_
  <tr class="hide_right">_x000D_
    <td>21</td>_x000D_
    <td>22</td>_x000D_
    <td>23</td>_x000D_
  </tr>_x000D_
  <tr class="hide_all">_x000D_
    <td>31</td>_x000D_
    <td>32</td>_x000D_
    <td>33</td>_x000D_
  </tr>_x000D_
</table>

According to Python3 documentation,python when divided by integer,will generate float despite expected to be integer.

For exclusively printing integer,use floor division method. Floor division is rounding off zero and removing decimal point. Represented by //

Hence,instead of 2/2 ,use 2//2

You can also import division from __future__ irrespective of using python2 or python3.

Hope it helps!

INSERT statements that use VALUES syntax can insert multiple rows. To do this, include multiple lists of column values, each enclosed within parentheses and separated by commas.

Example:

INSERT INTO tbl_name
    (a,b,c)
VALUES
    (1,2,3),
    (4,5,6),
    (7,8,9);

Yes, the constant CI_VERSION will give you the current CodeIgniter version number. It's defined in: /system/codeigniter/CodeIgniter.php As of CodeIgniter 2, it's defined in /system/core/CodeIgniter.php

For example,

echo CI_VERSION; // echoes something like 1.7.1

You are probably looking for 'chr()':

>>> L = [104, 101, 108, 108, 111, 44, 32, 119, 111, 114, 108, 100]
>>> ''.join(chr(i) for i in L)
'hello, world'

Why can't we create Object of Abstract Class ? When we create a pure virtual function in Abstract class, we reserve a slot for a function in the VTABLE(studied in last topic), but doesn't put any address in that slot. Hence the VTABLE will be incomplete. As the VTABLE for Abstract class is incomplete, hence the compiler will not let the creation of object for such class and will display an errror message whenever you try to do so.

Pure Virtual definitions

Pure Virtual functions can be given a small definition in the Abstract class, which you want all the derived classes to have. Still you cannot create object of Abstract class. Also, the Pure Virtual function must be defined outside the class definition. If you will define it inside the class definition, complier will give an error. Inline pure virtual definition is Illegal.

You can..

Microsoft SLP ServicesInishTech's Software Potential offers the ability to help protect code without affecting the functionality of your applications.

UPDATE: (Disclosure: I work on Eazfuscator.NET) What makes Microsoft SLP ServicesSoftware Potential different is the ability to virtualize the code, so you definitely can. Several years passed since the question was originally asked; today there are more products available that also work on a similar basis such as:

• Agile.NET
• Eazfuscator.NET

exit(X), where X is a number (according to the doc) should work. But it is not recommended by Apple and won't be accepted by the AppStore. Why? Because of these guidelines (one of my app got rejected):

We found that your app includes a UI control for quitting the app. This is not in compliance with the iOS Human Interface Guidelines, as required by the App Store Review Guidelines.

Please refer to the attached screenshot/s for reference.

The iOS Human Interface Guidelines specify,

"Always Be Prepared to Stop iOS applications stop when people press the Home button to open a different application or use a device feature, such as the phone. In particular, people don’t tap an application close button or select Quit from a menu. To provide a good stopping experience, an iOS application should:

Save user data as soon as possible and as often as reasonable because an exit or terminate notification can arrive at any time.

Save the current state when stopping, at the finest level of detail possible so that people don’t lose their context when they start the application again. For example, if your app displays scrolling data, save the current scroll position."

> It would be appropriate to remove any mechanisms for quitting your app.

Plus, if you try to hide that function, it would be understood by the user as a crash.

For me helped only this code line:

I don't know if there is a better way, but the following describes how I did it with a counter and background worker thread.

private object _lock = new object();
private int _runningThreads = 0;

private int Counter{
    get{
        lock(_lock)
            return _runningThreads;
    }
    set{
        lock(_lock)
            _runningThreads = value;
    }
}

Now whenever you create a worker thread, increment the counter:

var t = new BackgroundWorker();
// Add RunWorkerCompleted handler

// Start thread
Counter++;

In work completed, decrement the counter:

private void RunWorkerCompleted(object sender, RunWorkerCompletedEventArgs e)
{
    Counter--;
}

Now you can check for the counter anytime to see if any thread is running:

if(Couonter>0){
    // Some thread is yet to finish.
}

Set it in the body selector of your css. E.g.

body {
    font: 16px Arial, sans-serif;
}

I would do something like this:

;WITH x 
 AS (SELECT *, 
            Row_number() 
              OVER( 
                partition BY employeeid 
                ORDER BY datestart) rn 
     FROM   employeehistory) 
SELECT * 
FROM   x x1 
   LEFT OUTER JOIN x x2 
                ON x1.rn = x2.rn + 1 

Or maybe it would be x2.rn - 1. You'll have to see. In any case, you get the idea. Once you have the table joined on itself, you can filter, group, sort, etc. to get what you need.

I tried Ninh Pham's solution but it didn't work for me until I tweaked it - see below. Remove contentType and don't encode your json data

$.fn.postJSON = function(url, data) {
    return $.ajax({
            type: 'POST',
            url: url,
            data: data,
            dataType: 'json'
        });

You can use WScript.ScriptFullName which will return the full path of the executing script.

You can then use string manipulation (jscript example) :

scriptdir = WScript.ScriptFullName.substring(0,WScript.ScriptFullName.lastIndexOf(WScript.ScriptName)-1)

Or get help from FileSystemObject, (vbscript example) :

scriptdir = CreateObject("Scripting.FileSystemObject").GetParentFolderName(WScript.ScriptFullName)

You could use the CSS calc parameter to calculate the height dynamically like so:

.dynamic-height {_x000D_
   color: #000;_x000D_
   font-size: 12px;_x000D_
   margin-top: calc(100% - 10px);_x000D_
   text-align: left;_x000D_
}

<div class='dynamic-height'>_x000D_
    <p>Lorem ipsum dolor sit amet, consectetuer adipiscing elit. Aenean commodo ligula eget dolor. Aenean massa. Cum sociis natoque penatibus et magnis dis parturient montes, nascetur ridiculus mus. Donec quam felis, ultricies nec, pellentesque eu, pretium quis, sem.</p>_x000D_
</div>

From Twitter Bootstrap documentation:

• small grid (= 768px) = .col-sm-*,
• medium grid (= 992px) = .col-md-*,
• large grid (= 1200px) = .col-lg-*.

to Read More...

You could try using float:left; or display:inline-block;.

Both of these will change the element's behaviour from defaulting to 100% width to defaulting to the natural width of its contents.

However, note that they'll also both have an impact on the layout of the surrounding elements as well. I would suggest that inline-block will have less of an impact though, so probably best to try that first.

The problem with this chunk of code:

class myDict(dict):
    def __init__(self):
        self._dict = {}

    def add(id, val):
        self._dict[id] = val


md = myDict()
md.add('id', 123)

...is that your 'add' method (...and any method you want to be a member of a class) needs to have an explicit 'self' declared as its first argument, like:

def add(self, 'id', 23):

To implement the operator overloading to access items by key, look in the docs for the magic methods __getitem__ and __setitem__.

Note that because Python uses Duck Typing, there may actually be no reason to derive your custom dict class from the language's dict class -- without knowing more about what you're trying to do (e.g, if you need to pass an instance of this class into some code someplace that will break unless isinstance(MyDict(), dict) == True), you may be better off just implementing the API that makes your class sufficiently dict-like and stopping there.

JFrame.dispose()

public void dispose()

Releases all of the native screen resources used by this Window, its subcomponents, and all of its owned children. That is, the resources for these Components will be destroyed, any memory they consume will be returned to the OS, and they will be marked as undisplayable. The Window and its subcomponents can be made displayable again by rebuilding the native resources with a subsequent call to pack or show. The states of the recreated Window and its subcomponents will be identical to the states of these objects at the point where the Window was disposed (not accounting for additional modifications between those actions).

Note: When the last displayable window within the Java virtual machine (VM) is disposed of, the VM may terminate. See AWT Threading Issues for more information.

System.exit()

public static void exit(int status)

Terminates the currently running Java Virtual Machine. The argument serves as a status code; by convention, a nonzero status code indicates abnormal termination. This method calls the exit method in class Runtime. This method never returns normally.

The call System.exit(n) is effectively equivalent to the call:

Runtime.getRuntime().exit(n)

If your app is a Scala app, it must have a build.sbt in the root directory, and that file must be checked into Git. You can confirm this by running:

$ git ls-files build.sbt

If that file exists and is checked into Git, try running this command:

$ heroku buildpacks:set heroku/scala

Just want to open the app through browser? You can achieve it using below code:

HTML:

<a href="intent:#Intent;action=packageName;category=android.intent.category.DEFAULT;category=android.intent.category.BROWSABLE;end">Click here</a>

Manifest:

<intent-filter>
      <action android:name="packageName" />
      <category android:name="android.intent.category.DEFAULT" />
      <category android:name="android.intent.category.BROWSABLE" />
</intent-filter>

This intent filter should be in Launcher Activity.

Recently we released a gem that implements Enums in Ruby. In my post you will find the answers on your questions. Also I described there why our implementation is better than existing ones (actually there are many implementations of this feature in Ruby yet as gems).

table.setDefaultEditor(Object.class, null);

I know, that question has been asked a long long time ago...

I was looking for a short and elegant solution, but couldn't find satisfaction for two reasons:

First, most of the existing solutions replace a list of characters by a list of other characters. Unfortunately, it require to use a specific encoding for the php script file itself which might be unwanted.

Second, using iconv seems to be a good way, but it's not enough as the result of a converted character could be one or two characters, or a Fatal Exception.

So I wrote that small function which does the job :

function replaceAccent($string, $replacement = '_')
{
    $alnumPattern = '/^[a-zA-Z0-9 ]+$/';

    if (preg_match($alnumPattern, $string)) {
        return $string;
    }

    $ret = array_map(
        function ($chr) use ($alnumPattern, $replacement) {
            if (preg_match($alnumPattern, $chr)) {
                return $chr;
            } else {
                $chr = @iconv('ISO-8859-1', 'ASCII//TRANSLIT', $chr);
                if (strlen($chr) == 1) {
                    return $chr;
                } elseif (strlen($chr) > 1) {
                    $ret = '';
                    foreach (str_split($chr) as $char2) {
                        if (preg_match($alnumPattern, $char2)) {
                            $ret .= $char2;
                        }
                    }
                    return $ret;
                } else {
                    // replace whatever iconv fail to convert by something else
                    return $replacement;
                }
            }
        },
        str_split($string)
    );

    return implode($ret);
}

GRANT ALL PRIVILEGES ON mydb.* TO myuser@localhost IDENTIFIED BY 'mypasswd';

Works for privileges on schema :)

Optional: after mypasswd you can add WITH GRANT OPTION

The method argument specifies the parameter of the smooth statistic. You can see stat_smooth for the list of all possible arguments to the method argument.

I put this:

@implementation NSObject (AdditionalMethod)
-(BOOL) isNotEmpty
{
    return !(self == nil
    || [self isKindOfClass:[NSNull class]]
    || ([self respondsToSelector:@selector(length)]
        && [(NSData *)self length] == 0)
    || ([self respondsToSelector:@selector(count)]
        && [(NSArray *)self count] == 0));

};
@end

The problem is that if self is nil, this function is never called. It'll return false, which is desired.

?+?+?/?/?/? will let you navigate split panes in the direction of the arrow, i.e. when using ?+D to split panes vertically, ?+?+? and ?+?+? will let you switch between the panes.

When you are checking if an element has or does not have a class, make sure you didn't accidentally put a dot in the class name:

<div class="className"></div>

$('div').hasClass('className');
$('div').hasClass('.className'); #will not work!!!!

After a long time of staring at my code I realized I had done this. A little typo like this took me an hour to figure out what I had done wrong. Check your code!

Activate the virtualenv, and then install BeautifulSoup4:

$ pip install BeautifulSoup4

When you installed bs4 with easy_install, you installed it system-wide. So your system python can import it, but not your virtualenv python. If you do not need bs4 to be installed in your system python path, uninstall it and keep it in your virtualenv.

For more information about virtualenvs, read this

Use awk like this:

awk -v start=1 -v end=10 'BEGIN{for (i=start; i<=end; i++) printf("%05d\n", i)}'

OUTPUT:

00001
00002
00003
00004
00005
00006
00007
00008
00009
00010

Update:

As pure bash alternative you can do this to get same output:

for i in {1..10}
do
   printf "%05d\n" $i
done

This way you can avoid using an external program seq which is NOT available on all the flavors of *nix.

This is just an informational message. Your issue might be a missmatch between the versions of chromedriver and selenium-server-standalone.

Try with the latest selenium version 3.0, it is working for me.

Please not that for selenium 3.0 you need to specify the driver first and after the selenium server.

With the new selenium, which is 3.0 you should use:

java -Dwebdriver.chrome.driver=path_to_chrome_driver -jar selenium-server-standalone-3.0.0-beta2.jar If you are using selenium version below 3.0 you need to reverse the order of selenium with the driver, like:

java -Dwebdriver.chrome.driver=path_to_chrome_driver -jar selenium_server.jar

When you are starting the selenium server, open a console in the directory with chromedriver and selenium server and execute the above command.

I faced a similar problem, trying to test if jQuery is already present on a page, and if not force it's load, and then execute a function. I tried with @David Hellsing workaround, but with no chance for my needs. In fact, the onload instruction was immediately evaluated, and then the $ usage inside this function was not yet possible (yes, the huggly "$ is not a function." ^^).

So, I referred to this article : https://developer.mozilla.org/fr/docs/Web/Events/load and attached a event listener to my script object.

var script = document.createElement('script');
script.type = "text/javascript";
script.addEventListener("load", function(event) {
    console.log("script loaded :)");
    onjqloaded();
});
script.src = "https://ajax.googleapis.com/ajax/libs/jquery/3.3.1/jquery.min.js";
document.getElementsByTagName('head')[0].appendChild(script);

For my needs, it works fine now. Hope this can help others :)

Nope. No way to do that natively. You're going to have to subclass UIImageView, and add an imageFileName property (which you set when you set the image).

Zxing is an excellent library to perform Qr code scanning and generation. The following implementation uses Zxing library to scan the QR code image Don't forget to add following dependency in the build.gradle

implementation 'me.dm7.barcodescanner:zxing:1.9'

Code scanner activity:

    public class QrCodeScanner extends AppCompatActivity implements ZXingScannerView.ResultHandler {
        private ZXingScannerView mScannerView;

        @Override
        public void onCreate(Bundle state) {
            super.onCreate(state);
            // Programmatically initialize the scanner view
            mScannerView = new ZXingScannerView(this);
            // Set the scanner view as the content view
            setContentView(mScannerView);
        }

        @Override
        public void onResume() {
            super.onResume();
            // Register ourselves as a handler for scan results.
            mScannerView.setResultHandler(this);
            // Start camera on resume
            mScannerView.startCamera();
        }

        @Override
        public void onPause() {
            super.onPause();
            // Stop camera on pause
            mScannerView.stopCamera();
        }

        @Override
        public void handleResult(Result rawResult) {
            // Do something with the result here
            // Prints scan results
            Logger.verbose("result", rawResult.getText());
            // Prints the scan format (qrcode, pdf417 etc.)
            Logger.verbose("result", rawResult.getBarcodeFormat().toString());
            //If you would like to resume scanning, call this method below:
            //mScannerView.resumeCameraPreview(this);
            Intent intent = new Intent();
            intent.putExtra(AppConstants.KEY_QR_CODE, rawResult.getText());
            setResult(RESULT_OK, intent);
            finish();
        }
    }

def map = [:]

  var queryString=urlparts.join("?"); 

  var prefix = encodeURIComponent(parameter)+'=';
  var pars = queryString.split(/[&;]/g);
  for (var i= pars.length; i-->0;)               
      if (pars[i].lastIndexOf(prefix, 0)!==-1)   
          pars.splice(i, 1);
  url = urlBase+'?'+pars.join('&');
  window.history.pushState('',document.title,url); // added this line to push the new url directly to url bar .

}
return url;
}

This will resolve your problem

It is possible to override the compatibility mode in intranet.

For IIS, just add the below code to the web.config. Worked for me with IE9.

<system.webServer>
  <httpProtocol>
    <customHeaders>
      <clear />
      <add name="X-UA-Compatible" value="IE=edge" />
    </customHeaders>
  </httpProtocol>
</system.webServer> 

Equivalent for Apache:

Header set X-UA-Compatible: IE=Edge

And for nginx:

add_header "X-UA-Compatible" "IE=Edge";

And for express.js:

res.set('X-UA-Compatible', 'IE=Edge')

First create the database and table, manually adding the columns. In which column to be primary key. You should right click this column and set primary key and set the seed value of the primary key.

NSString * str = [componentsJoinedByString:@""];

and you have dic or multiple array then used bellow

NSString * result = [[array valueForKey:@"description"] componentsJoinedByString:@""];   

It's suggested that you do not use return false, as 3 things occur as a result:

1. event.preventDefault();
2. event.stopPropagation();
3. Stops callback execution and returns immediately when called.

So in this type of situation, you should really only use event.preventDefault();

$('#selectBox option[value="3"]').attr('selected', true);

I think one Benefit of using Nested Scroll view is that the cooridinator layout only listens for nested scroll events. So if for ex. you want the toolbar to scroll down when you scroll you content of activity, it will only scroll down when you are using nested scroll view in your layout. If you use a normal scroll view in your layout, the toolbar wont scroll when the user scrolls the content.

<button onclick="set_mouse()">focus</button>

It is very hard set caret in proper position when you have advance element like (p) (span) etc. The goal is to get (object text):

<div id="editable" contenteditable="true">dddddddddddddddddddddddddddd<p>dd</p>psss<p>dd</p>
    <p>dd</p>
    <p>text text text</p>
</div>
<p id='we'></p>
<button onclick="set_mouse()">focus</button>
<script>

    function set_mouse() {
        var as = document.getElementById("editable");
        el = as.childNodes[1].childNodes[0];//goal is to get ('we') id to write (object Text) because it work only in object text
        var range = document.createRange();
        var sel = window.getSelection();
        range.setStart(el, 1);
        range.collapse(true);
        sel.removeAllRanges();
        sel.addRange(range);

        document.getElementById("we").innerHTML = el;// see out put of we id
    }
</script>

What about:

datetime.now().strftime('%M:%S.%f')[:-4]

I'm not sure what you mean by "Milliseconds only 2 digits", but this should keep it to 2 decimal places. There may be a more elegant way by manipulating the strftime format string to cut down on the precision as well -- I'm not completely sure.

EDIT

If the %f modifier doesn't work for you, you can try something like:

now=datetime.now()
string_i_want=('%02d:%02d.%d'%(now.minute,now.second,now.microsecond))[:-4]

Again, I'm assuming you just want to truncate the precision.

MySQL Server version

If you say that it works with accessing directly manageproducts.do?option=1 in the browser then it should work with:

$.get('manageproducts.do', { option: '1' }, function(data) {
    ...
});

as it would send the same GET request.

For powershell in Windows, you can add relative path + filename to --output flag:

curl -L  http://github.com/GorvGoyl/Notion-Boost-browser-extension/archive/master.zip --output build_firefox/master-repo.zip

here build_firefox is relative folder.

Since name is a (immutable) NSString, copy or retain makes no difference if you set another NSString to name. In another word, copy behaves just like retain, increasing the reference count by one. I think that is an automatic optimization for immutable classes, since they are immutable and of no need to be cloned. But when a NSMutalbeString mstr is set to name, the content of mstr will be copied for the sake of correctness.

protected void CheckedRecords(object sender, EventArgs e)

    {
       string email = string.Empty;
        foreach (GridViewRow gridrows in GridView1.Rows)

        {

            CheckBox chkbox = (CheckBox)gridrows.FindControl("ChkRecords");
    if (chkbox != null & chkbox.Checked)

            {

    int columnIndex = 0;
                foreach (DataControlFieldCell cell in gridrows.Cells)
                {
                    if (cell.ContainingField is BoundField)
                        if (((BoundField)cell.ContainingField).DataField.Equals("UserEmail"))
                            break;
                    columnIndex++; 
                }


                email += gridrows.Cells[columnIndex].Text + ',';
                  }

        }

        Label1.Text = "email:" + email;

    }                           

To change the connect mode selection try Settings -> Wireless & Networks -> USB Connection. You can shoose to Charging, Mass Storage, Tethered, and ask on connection.

And for JavaScript source format you can use Dreamweaver JavaScript source formatting extension.(available on adobe)

Using Javascript, you can make the two div tags the same height. The smaller div will adjust to be the same height as the tallest div tag using the code shown below:

var rightHeight = document.getElementById('right').clientHeight;
var leftHeight = document.getElementById('left').clientHeight;
if (leftHeight > rightHeight) {
document.getElementById('right').style.height=leftHeight+'px';
} else {
document.getElementById('left').style.height=rightHeight+'px';
}

With "left" and "right" being the id's of the div tags.

There is no interactive solution in Excel because some functions are not vector-friendly, like CELL, above quoted. For example, it's possible counting all the numbers whose absolute value is less than 3, because ABS is accepted inside a formula array.

So I've used the following array formula (Ctrl+Shift+Enter after edit with no curly brackets)

             ={SUM(IF(ABS(F1:F15)<3,1,0))}

If Column F has

                   F
          1 ...    2
          2 ....   4
          3 ....  -2
          4 ....   1
          5 .....  5

It counts 3! (-2,2 and 1). In order to show how ABS is array-friendly function let's do a simple test: Select G1:G5, digit =ABS(F1:F5) in the formula bar and press Ctrl+Shift+Enter. It's like someone write Abs(F1:F5)(1), Abs(F1:F5)(2), etc.

                   F    G
          1 ...    2  =ABS(F1:F5) => 2 
          2 ....   4  =ABS(F1:F5) => 4
          3 ....  -2  =ABS(F1:F5) => 2
          4 ....   1  =ABS(F1:F5) => 1
          5 .....  5  =ABS(F1:F5) => 5

Now I put some mixed data, including 2 date values.

                   F
          1 ...    Fab-25-2012
          2 ....   4
          3 ....   May-5-2013
          4 ....   Ball
          5 .....  5

In this case, CELL fails and return 1

             ={SUM(IF(CELL("format",F1:F15)="D4",1,0))}

It happens because CELL return the format of first cell of the range. (D4 is a m-d-y format)

So the only thing left is programming! A UDF(User defined Function) for formula array must return a variant array:

Function TypeCell(R As Range) As Variant
Dim V() As Variant
Dim Cel As Range
Dim I As Integer
Application.Volatile '// For revaluation in interactive environment
ReDim V(R.Cells.Count - 1) As Variant
I = 0
For Each Cel In R
   V(I) = VarType(Cel) '// Output array has the same size of input range.
   I = I + 1
Next Cel
TypeCell = V
End Function

Now is easy (the constant VbDate is 7):

             =SUM(IF(TypeCell(F1:F5)=7,1,0))  

It shows 2. That technique can be used for any shape of cells. I've tested vertical, horizontal and rectangular shapes, since you fill using for each order inside the function.

Just to cover an edge case:) and because the question title asks (at least now) how to copy the output of a command directly to clipboard.

Often times I find it useful to copy the output of the command after it was already executed and I don’t want to or can’t execute the command again.

For this scenario, we can either use gdm or a similar mouse utility and select using the mouse. apt-get install gdm and then either the right click or the Cntrl+Shift+c and Cntrl+Shift+v combinations for copy and paste in the terminal

Or, which is the preferred method for me (as the mouse cannot select properly inside one pane when you have multiple panes side by side and you need to select more than one line), using tmux we can copy into the tmux buffer using the standard [ , space , move to select , enter or you can select a block of code. Also this is particularly useful when you are inside one of the lanes of the cli multiplexer like tmux AND you need to select a bunch of text, but not the line numbers (my vim setup renders line numbers)

After this you can use the command:

tmux save-buffer - | xclip -i

You can of course alias it to something you like or bind directly in the tmux configuration file

This is just to give you a conceptual answer to cover this edge case when it’s not possible to execute the command again. If you need more specific code examples, let me know

Cheers

There are three event handlers bound. If we don’t stop any propagation, then there should be four alerts - three on the child div, and one on the parent div.

If we stop the event from propagating, then there will be 3 alerts (all on the inner child div). Since the event won’t propagate up the DOM hierarchy, the parent div won’t see it, and its handler won’t fire.

If we stop propagation immediately, then there will only be 1 alert. Even though there are three event handlers attached to the inner child div, only 1 is executed and any further propagation is killed immediately, even within the same element.

Also, if you have two subsequent words in regular text and you want to avoid a line break between them, you can use the ~ character.

For example:

As we can see in Fig.~\ref{BlaBla}, there is nothing interesting to see. A~better place..

This can ensure that you don't have a line starting with a figure number (without the Fig. part) or with an uppercase A.

If your page is missing meta[@name="viewport"] element within its DOM, then the following could be used to detect a mobile device:

@media only screen and (width: 980px), (hover: none) { … }

If you want to avoid false-positives with desktops that just magically have their viewport set to 980px like all the mobile browsers do, then a device-width test could also be added into the mix:

@media only screen and (max-device-width: 800px) and (width: 980px), (hover: none) { … }

Per the list at https://developer.mozilla.org/en-US/docs/Web/CSS/Media_Queries/Using_media_queries, the new hover property would appear to be the final new way to detect that you've got yourself a mobile device that doesn't really do proper hover; it's only been introduced in 2018 with Firefox 64 (2018), although it's been supported since 2016 with Android Chrome 50 (2016), or even since 2014 with Chrome 38 (2014):

jQuery.load() is probably the easiest way to load data asynchronously using a selector, but you can also use any of the jquery ajax methods (get, post, getJSON, ajax, etc.)

Note that load allows you to use a selector to specify what piece of the loaded script you want to load, as in

$("#mydiv").load(location.href + " #mydiv");

Note that this technically does load the whole page and jquery removes everything but what you have selected, but that's all done internally.

If you want to specifically animate the background color of an element, I believe you need to include jQueryUI framework. Then you can do:

$('#myElement').animate({backgroundColor: '#FF0000'}, 'slow');

jQueryUI has some built-in effects that may be useful to you as well.

Yet another option is to have, in Ticket, one column specifying the owning entity type (User or Group), second column with referenced User or Group id and NOT to use Foreign Keys but instead rely on a Trigger to enforce referential integrity.

Two advantages I see here over Nathan's excellent model (above):

• More immediate clarity and simplicity.
• Simpler queries to write.

Try this

DateTime startTime = varValue
DateTime endTime = varTime

TimeSpan span = endTime.Subtract ( startTime );
Console.WriteLine( "Time Difference (minutes): " + span.TotalMinutes );

Edit: If are you trying 'span.Minutes', this will return only the minutes of timespan [0~59], to return sum of all minutes from this interval, just use 'span.TotalMinutes'.

It's simpler than I initially thought.. Basically you have a page that does nothing, until the data you want to send is available (say, a new message arrives).

Here is a really basic example, which sends a simple string after 2-10 seconds. 1 in 3 chance of returning an error 404 (to show error handling in the coming Javascript example)

msgsrv.php

<?php
if(rand(1,3) == 1){
    /* Fake an error */
    header("HTTP/1.0 404 Not Found");
    die();
}

/* Send a string after a random number of seconds (2-10) */
sleep(rand(2,10));
echo("Hi! Have a random number: " . rand(1,10));
?>

Note: With a real site, running this on a regular web-server like Apache will quickly tie up all the "worker threads" and leave it unable to respond to other requests.. There are ways around this, but it is recommended to write a "long-poll server" in something like Python's twisted, which does not rely on one thread per request. cometD is an popular one (which is available in several languages), and Tornado is a new framework made specifically for such tasks (it was built for FriendFeed's long-polling code)... but as a simple example, Apache is more than adequate! This script could easily be written in any language (I chose Apache/PHP as they are very common, and I happened to be running them locally)

Then, in Javascript, you request the above file (msg_srv.php), and wait for a response. When you get one, you act upon the data. Then you request the file and wait again, act upon the data (and repeat)

What follows is an example of such a page.. When the page is loaded, it sends the initial request for the msgsrv.php file.. If it succeeds, we append the message to the #messages div, then after 1 second we call the waitForMsg function again, which triggers the wait.

The 1 second setTimeout() is a really basic rate-limiter, it works fine without this, but if msgsrv.php always returns instantly (with a syntax error, for example) - you flood the browser and it can quickly freeze up. This would better be done checking if the file contains a valid JSON response, and/or keeping a running total of requests-per-minute/second, and pausing appropriately.

If the page errors, it appends the error to the #messages div, waits 15 seconds and then tries again (identical to how we wait 1 second after each message)

The nice thing about this approach is it is very resilient. If the clients internet connection dies, it will timeout, then try and reconnect - this is inherent in how long polling works, no complicated error-handling is required

Anyway, the long_poller.htm code, using the jQuery framework:

You can add a NuGet package CefSharp.WinForms to your application and then add a ChromiumWebBroweser control to your form. In the code you can write:

chromiumWebBrowser1.Load(filePath);

This is the easiest solution I have found, it is completely free and independent of the user's computer settings like it would be when using default WebBrowser control.

# VIM: Temperory files

# VIM: Swap-files

The name of the swap file is normally the same as the file you are editing, with the extension ".swp".

• On Unix, a '.' is prepended to swap file names in the same directory as the edited file. This avoids that the swap file shows up in a directory listing.
• On MS-DOS machines and when the 'shortname' option is on, any '.' in the original file name is replaced with '_'.
• If this file already exists (e.g., when you are recovering from a crash) a warning is given and another extension is used, ".swo", ".swn", etc.
• An existing file will never be overwritten.
• The swap file is deleted as soon as Vim stops editing the file.

The replacement of '.' with '_' is done to avoid problems with MS-DOS compatible filesystems (e.g., crossdos, multidos).

git log --full-history -- [file path] shows the changes of a file and works even if the file was deleted.

Example:

git log --full-history  -- myfile

If you want to see only the last commit, which deleted the file, use -1 in addition to the command above. Example:

git log --full-history -1 -- [file path]

See also my article: Which commit deleted a file.

You can also use logical tests

x <- data.frame(a = c(0,1,2,NA), b = c(0,NA,1,2), c = c(NA, 0, 1, 2)) 
x
x$a <- replace(x$a, is.na(x$a), 0)
x
x$b <- replace(x$b, x$b==2, 333)

You need to do some escaping I think.

Here is a solution for Visual Studio 2017. The installer looks a littlebit different from the VS 2015 version and the name of the installation packages are different.

As stated by others, your question is ambiguous at best. The problem is, you want to represent the object as a string, and then be able to construct the object again from that string.

However, note that while many object types in Java have string representations, this does not guarantee that an object can be constructed from its string representation.

To quote this source,

Object serialization is the process of saving an object's state to a sequence of bytes, as well as the process of rebuilding those bytes into a live object at some future time.

So, you see, what you want might not be possible. But it is possible to save your object's state to a byte sequence, and then reconstruct it from that byte sequence.

if( strpos( $url, $word ) !== false ) {
    // Do something
}

If your float is always expressed in decimal notation something like

>>> import re
>>> re.findall("\d+\.\d+", "Current Level: 13.4 db.")
['13.4']

may suffice.

A more robust version would be:

>>> re.findall(r"[-+]?\d*\.\d+|\d+", "Current Level: -13.2 db or 14.2 or 3")
['-13.2', '14.2', '3']

If you want to validate user input, you could alternatively also check for a float by stepping to it directly:

user_input = "Current Level: 1e100 db"
for token in user_input.split():
    try:
        # if this succeeds, you have your (first) float
        print float(token), "is a float"
    except ValueError:
        print token, "is something else"

# => Would print ...
#
# Current is something else
# Level: is something else
# 1e+100 is a float
# db is something else

The easiest way might be to get it from NuGet:

http://www.nuget.org/packages/System.Windows.Interactivity.WPF/

You can use a std::map to map the input to your enum:

#include <iostream>
#include <string>
#include <map>
using namespace std;

enum level {easy, medium, hard};
map<string, level> levels;

void register_levels()
{
    levels["easy"]   = easy;
    levels["medium"] = medium;
    levels["hard"]   = hard;
}

int main()
{
    register_levels();
    string input;
    cin >> input;
    switch( levels[input] )
    {
    case easy:
        cout << "easy!"; break;
    case medium:
        cout << "medium!"; break;
    case hard:
        cout << "hard!"; break;
    }
}

You can use GCD (in the example with a 10 second delay):

Swift 2

let triggerTime = (Int64(NSEC_PER_SEC) * 10)
dispatch_after(dispatch_time(DISPATCH_TIME_NOW, triggerTime), dispatch_get_main_queue(), { () -> Void in
    self.functionToCall()
})

Swift 3 and Swift 4

DispatchQueue.main.asyncAfter(deadline: .now() + 10.0, execute: {
    self.functionToCall()
})

Swift 5 or Later

 DispatchQueue.main.asyncAfter(deadline: .now() + 10.0) {
        //call any function
    }

On Linux

(tested in Ununtu KDE)

There is the option in the menu, under Edit > Lines > Auto Indent or press Cmd + Shift + p, search for Editor: Auto Indent by entering just "ai"

Note: In KDE ctrl-alt-l is already globally set for "lock screen" so better use ctrl-alt-i instead.

You can add a key mapping in Atom:

• Cmd + Shift + p, search for "Settings View: Show Keybindings"
• click on "your keymap file"

• Add a section there like this one:

   'atom-text-editor':
      'ctrl-alt-i': 'editor:auto-indent'
  

If the indention is not working, it can be a reason, that the file-ending is not recognized by Atom. Add the support for your language then, for example for "Lua" install the package "language-lua".

If a File is not recognized for your language:

• open the ~/.atom/config.cson file (by CTRL+SHIFT+p: type ``open config'')

• add/edit a customFileTypes section under core for example like the following:

  core:
    customFileTypes:
      "source.lua": [
        "conf"
      ]
      "text.html.php": [
        "thtml"
      ]
  

(You find the languages scope names ("source.lua", "text.html.php"...) in the language package settings see here)

Iterate through a dict and sort it by its values in descending order:

$ python --version
Python 3.2.2

$ cat sort_dict_by_val_desc.py 
dictionary = dict(siis = 1, sana = 2, joka = 3, tuli = 4, aina = 5)
for word in sorted(dictionary, key=dictionary.get, reverse=True):
  print(word, dictionary[word])

$ python sort_dict_by_val_desc.py 
aina 5
tuli 4
joka 3
sana 2
siis 1

Please refer below Ajax overview:

http://msdn.microsoft.com/en-us/library/bb386454.aspx

Because if you want to trigger your data with deep of it,you have to pass 3th argument true of your listener.By default it's false and it meens that you function will trigger,only when your variable will change not it's field.

I moved the tsconfig.json file into a new folder to restructure my project.

So it wasn't able to resolve the path to node_modules/@types folder inside typeRoots property of tsconfig.json

So just update the path from

"typeRoots": [
  "../node_modules/@types"
]

to

"typeRoots": [
  "../../node_modules/@types"
]

To just ensure that the path to node_modules is resolved from the new location of the tsconfig.json

jQuery UI has it's own elements, but jQuery alone hasn't.

http://jqueryui.com/dialog/

Working example:

<!doctype html>

<html lang="en">
<head>
  <meta charset="utf-8" />
  <title>jQuery UI Dialog - Default functionality</title>
  <link rel="stylesheet" href="http://code.jquery.com/ui/1.10.3/themes/smoothness/jquery-ui.css" />
  <script src="http://code.jquery.com/jquery-1.9.1.js"></script>
  <script src="http://code.jquery.com/ui/1.10.3/jquery-ui.js"></script>
  <link rel="stylesheet" href="/resources/demos/style.css" />
  <script>
  $(function() {
    $( "#dialog" ).dialog();
  });
  </script>
</head>
<body>

<div id="dialog" title="Basic dialog">
  <p>This is the default dialog which is useful for displaying information. The dialog window can be moved, resized and closed with the 'x' icon.</p>
</div>


</body>
</html>

Well your jsonString is wrong.

String jsonString = "{\"stat\":{\"sdr\": \"aa:bb:cc:dd:ee:ff\",\"rcv\": \"aa:bb:cc:dd:ee:ff\",\"time\": \"UTC in millis\",\"type\": 1,\"subt\": 1,\"argv\": [{\"1\":2},{\"2\":3}]}}";

use this jsonString and if you use the same JSONParser and ContainerFactory in the example you will see that it will be encoded/decoded.

Additionally if you want to print your string after stat here it goes:

     try{
        Map json = (Map)parser.parse(jsonString, containerFactory);
        Iterator iter = json.entrySet().iterator();
        System.out.println("==iterate result==");
        Object entry = json.get("stat");
        System.out.println(entry);
      }

And about the json libraries, there are a lot of them. Better you check this.

I would like to add a solution, that have helpt me to solve this problem in entity framework:

var eventsCustom = eventCustomRepository.FindAllEventsCustomByUniqueStudentReference(userDevice.UniqueStudentReference)
                .Where(x =>  x.DateTimeStart.Year == currentDateTime.Year &&
                             x.DateTimeStart.Month== currentDateTime.Month &&
                             x.DateTimeStart.Day == currentDateTime.Day
    );

I hope that it helps.

I have found a better way which works on Laravel 5.5 and makes variables accessible by views. And you can retrieve data from the database, do your logic by importing your Model just as you would in your controller.

The "*" means you are referencing all views, if you research more you can choose views to affect.

add in your app/Providers/AppServiceProvider.php

<?php

    namespace App\Providers;

    use Illuminate\Contracts\View\View;

    use Illuminate\Support\ServiceProvider;
    use App\Setting;

class AppServiceProvider extends ServiceProvider
{
    /**
     * Bootstrap any application services.
     *
     * @return void
    */
    public function boot()
    {
        // Fetch the Site Settings object
        view()->composer('*', function(View $view) {
            $site_settings = Setting::all();
            $view->with('site_settings', $site_settings);
        });
    }

    /**
     * Register any application services.
     *
     * @return void
     */
    public function register()
    {

    }
}

Before installing ipython, I installed modules through easy_install; say sudo easy_install mechanize.

After installing ipython, I had to re-run easy_install for ipython to recognize the modules.

Great article i found what worked best for me was to add a % to the size

.wrap {
margin-top:5%;

If like me you recently moved certain classes to different packages ect. and you use android navigation. Make sure to change the argType to you match you new package address. from:

app:argType="com.example.app.old.Item" 

to:

app:argType="com.example.app.new.Item" 

If you want to launch from a batch file:

• for x86

  start "" "%SYSTEMDRIVE%\Program Files (x86)\Git\bin\sh.exe" --login
  

• for x64

  start "" "%PROGRAMFILES%\Git\bin\sh.exe" --login
  

If you have the program and the core file, you can do the following steps.

1) Run the gdb on the program along with core file

 $gdb ./test core

2) type info files and see what different segments are there in the core file.

    (gdb)info files

A sample output:

    (gdb)info files 

    Symbols from "/home/emntech/debugging/test".
    Local core dump file:

  0xb77cc000 - 0xb77ce000 is load14
  0xbf91d000 - 0xbf93f000 is load15

In my case I have 15 segments. Each segment has start of the address and end of the address. Choose any segment to search data for. For example lets select load11 and search for a pattern. Load11 has start address 0x08049000 and ends at 0x804a000.

3) Search for a pattern in the segment.

(gdb) find /w 0x08049000 0x0804a000 0x8048034
 0x804903c
 0x8049040
 2 patterns found

If you don't have executable file you need to use a program which prints data of all segments of a core file. Then you can search for a particular data at an address. I don't find any program as such, you can use the program at the following link which prints data of all segments of a core or an executable file.

Updated Answer

As of June11, 2018 it is now mandatory to have a billing account to get API key. You can still make keyless calls to the Maps JavaScript API and Street View Static API which will return low-resolution maps that can be used for development. Enabling billing still gives you $200 free credit monthly for your projects.

This answer is no longer valid

As long as you're using a testing API key it is free to register and use. But when you move your app to commercial level you have to pay for it. When you enable billing, google gives you $200 credit free each month that means if your app's map usage is low you can still use it for free even after the billing enabled, if it exceeds the credit limit now you have to pay for it.

for me , using export PYTHONIOENCODING=UTF-8 before executing python command worked .

Note: when it says "B5" in the explanation below, it actually means "B{current_row}", so for C5 it's B5, for C6 it's B6 and so on. Unless you specify $B$5 - then you refer to one specific cell.

This is supported in Google Sheets as of 2015: https://support.google.com/drive/answer/78413#formulas

In your case, you will need to set conditional formatting on B5.

• Use the "Custom formula is" option and set it to =B5>0.8*C5.
• set the "Range" option to B5.
• set the desired color

You can repeat this process to add more colors for the background or text or a color scale.

Even better, make a single rule apply to all rows by using ranges in "Range". Example assuming the first row is a header:

• On B2 conditional formatting, set the "Custom formula is" to =B2>0.8*C2.
• set the "Range" option to B2:B.
• set the desired color

Will be like the previous example but works on all rows, not just row 5.

Ranges can also be used in the "Custom formula is" so you can color an entire row based on their column values.

(char)myint;

for example:

Console.WriteLine("(char)122 is {0}", (char)122);

yields:

(char)122 is z

IFNULL, see here: http://www.sqlite.org/lang_corefunc.html#ifnull

no brackets around the function

Sending and receiving data in JSON format using POST method

// Sending and receiving data in JSON format using POST method
//
var xhr = new XMLHttpRequest();
var url = "url";
xhr.open("POST", url, true);
xhr.setRequestHeader("Content-Type", "application/json");
xhr.onreadystatechange = function () {
    if (xhr.readyState === 4 && xhr.status === 200) {
        var json = JSON.parse(xhr.responseText);
        console.log(json.email + ", " + json.password);
    }
};
var data = JSON.stringify({"email": "[email protected]", "password": "101010"});
xhr.send(data);

Sending and receiving data in JSON format using GET method

// Sending a receiving data in JSON format using GET method
//      
var xhr = new XMLHttpRequest();
var url = "url?data=" + encodeURIComponent(JSON.stringify({"email": "[email protected]", "password": "101010"}));
xhr.open("GET", url, true);
xhr.setRequestHeader("Content-Type", "application/json");
xhr.onreadystatechange = function () {
    if (xhr.readyState === 4 && xhr.status === 200) {
        var json = JSON.parse(xhr.responseText);
        console.log(json.email + ", " + json.password);
    }
};
xhr.send();

Handling data in JSON format on the server-side using PHP

<?php
// Handling data in JSON format on the server-side using PHP
//
header("Content-Type: application/json");
// build a PHP variable from JSON sent using POST method
$v = json_decode(stripslashes(file_get_contents("php://input")));
// build a PHP variable from JSON sent using GET method
$v = json_decode(stripslashes($_GET["data"]));
// encode the PHP variable to JSON and send it back on client-side
echo json_encode($v);

The limit of the length of an HTTP Get request is dependent on both the server and the client (browser) used, from 2kB - 8kB. The server should return 414 (Request-URI Too Long) status if an URI is longer than the server can handle.

Note Someone said that I could use state names instead of state values; in other words I could use xhr.readyState === xhr.DONE instead of xhr.readyState === 4 The problem is that Internet Explorer uses different state names so it's better to use state values.

I've only tested this in Rails 4 but there's an interesting way to use a range with a where hash to get this behavior.

User.where(id: 201..Float::INFINITY)

will generate the SQL

SELECT `users`.* FROM `users`  WHERE (`users`.`id` >= 201)

The same can be done for less than with -Float::INFINITY.

I just posted a similar question asking about doing this with dates here on SO.

>= vs >

To avoid people having to dig through and follow the comments conversation here are the highlights.

The method above only generates a >= query and not a >. There are many ways to handle this alternative.

For discrete numbers

You can use a number_you_want + 1 strategy like above where I'm interested in Users with id > 200 but actually look for id >= 201. This is fine for integers and numbers where you can increment by a single unit of interest.

If you have the number extracted into a well named constant this may be the easiest to read and understand at a glance.

Inverted logic

We can use the fact that x > y == !(x <= y) and use the where not chain.

User.where.not(id: -Float::INFINITY..200)

which generates the SQL

SELECT `users`.* FROM `users` WHERE (NOT (`users`.`id` <= 200))

This takes an extra second to read and reason about but will work for non discrete values or columns where you can't use the + 1 strategy.

Arel table

If you want to get fancy you can make use of the Arel::Table.

User.where(User.arel_table[:id].gt(200))

will generate the SQL

"SELECT `users`.* FROM `users` WHERE (`users`.`id` > 200)"

The specifics are as follows:

User.arel_table              #=> an Arel::Table instance for the User model / users table
User.arel_table[:id]         #=> an Arel::Attributes::Attribute for the id column
User.arel_table[:id].gt(200) #=> an Arel::Nodes::GreaterThan which can be passed to `where`

This approach will get you the exact SQL you're interested in however not many people use the Arel table directly and can find it messy and/or confusing. You and your team will know what's best for you.

Bonus

Starting in Rails 5 you can also do this with dates!

User.where(created_at: 3.days.ago..DateTime::Infinity.new)

will generate the SQL

SELECT `users`.* FROM `users` WHERE (`users`.`created_at` >= '2018-07-07 17:00:51')

Double Bonus

Once Ruby 2.6 is released (December 25, 2018) you'll be able to use the new infinite range syntax! Instead of 201..Float::INFINITY you'll be able to just write 201... More info in this blog post.

select * from yourtable where created < now() and created > '2011-04-25 04:00:00'

When inplace=True is passed, the data is renamed in place (it returns nothing), so you'd use:

df.an_operation(inplace=True)

When inplace=False is passed (this is the default value, so isn't necessary), performs the operation and returns a copy of the object, so you'd use:

df = df.an_operation(inplace=False) 

Merge two different eloquent collections into one and some objects happen to have the same id, one will overwrite the other. Use push() method instead or rethink your approach to the problem to avoid that. Refer to web

If you just want a number to come back try this.

create temp sequence temp_seq;
SELECT inline_v1.ROWNUM,inline_v1.c1
FROM
(
select nextval('temp_seq') as ROWNUM, c1 
from sometable
)inline_v1;

You can add a order by to the inline_v1 SQL so your ROWNUM has some sequential meaning to your data.

select nextval('temp_seq') as ROWNUM, c1 
from sometable
ORDER BY c1 desc;

Might not be the fastest, but it's an option if you really do need them.

On https://developer.mozilla.org/en-US/docs/Web/API/SubtleCrypto/digest I found this snippet that uses internal js module:

async function sha256(message) {
    // encode as UTF-8
    const msgBuffer = new TextEncoder().encode(message);                    

    // hash the message
    const hashBuffer = await crypto.subtle.digest('SHA-256', msgBuffer);

    // convert ArrayBuffer to Array
    const hashArray = Array.from(new Uint8Array(hashBuffer));

    // convert bytes to hex string                  
    const hashHex = hashArray.map(b => ('00' + b.toString(16)).slice(-2)).join('');
    return hashHex;
}

Note that crypto.subtle in only available on https or localhost - for example for your local development with python3 -m http.server you need to add this line to your /etc/hosts: 0.0.0.0 localhost

Reboot - and you can open localhost:8000 with working crypto.subtle.

Here's a way of doing it without having to loop through all the different roman numerals and their corresponding numbers. It has a constant time O(1) lookup, saving a little in time complexity.

It breaks down each integer from right to left, so 2,473 becomes 3 + 70 + 400 + 2,000, and then finds the corresponding roman numeral using the romanNumerals hash table, and appends it to the result string. It does this by adding an additional 0 to each integer before the lookup as you move right to left. This solution only works for numbers between 1 and 3,999.

    function integerToRoman(int) {
    if (int < 1 || int > 3999) {
        return -1;
    }

    var result = '';
    var intStr = int.toString();
    var romanNumerals = { 1: 'I', 2: 'II', 3: 'III', 4: 'IV', 5: 'V', 6: 'VI', 7: 'VII', 8: 'VIII', 9: 'IX', 10: 'X', 20: 'XX', 30: 'XXX', 40: 'XL', 50: 'L', 60: 'LX', 70: 'LXX', 80: 'LXXX', 90: 'XC', 100: 'C', 200: 'CC', 300: 'CCC', 400: 'CD', 500: 'D', 600: 'DC', 700: 'DCC', 800: 'DCCC', 900: 'CM', 1000: 'M', 2000: 'MM', 3000: 'MMM'};
    var digit = '';

    for (var i = intStr.length - 1; i >= 0; i-- ) {
        if (intStr[i] === '0') {
            digit += '0';
            continue;
        }
        var num = intStr[i] + digit;
        result = romanNumerals[num] + result;
        digit += '0';
    }

    return result;
}

tig is a possible alternative to using the git log command, available on the major open source *nix distributions.

On debian or ubuntu try installing and running as follows:

$ sudo apt-get install tig

For mac users, brew to the rescue :

$ brew install tig

(tig gets installed)

$ tig

[main] 531f35e925f53adeb2146dcfc9c6a6ef24e93619 - commit 1 of 32 (100%)

Since markdown doesn't support text coloring, imagine: column 1: blue; column 2: green; column 3: default text color. Last line, highlighted. Hit Q or q to exit.

tig justifies the columns without ragged edges, which an ascii tab (%x09) doesn't guarantee.

For a short date format hit capital D (note: lowercase d opens a diff view.) Configure it permanently by adding show-date = short to ~/.tigrc; or in a [tig] section in .git/configure or ~/.gitconfig.

To see an entire change:

• hit Enter. A sub pane will open in the lower half of the window.
• use k, j keys to scroll the change in the sub pane.
• at the same time, use the up, down keys to move from commit to commit.

Since tig is separate from git and apparently *nix specific, it probably requires cygwin to install on windows. But for fedora I believe the install commands are $ su, (enter root password), # yum install tig. For freebsd try % su, (enter root password), # pkg_add -r tig.

By the way, tig is good for a lot more than a quick view of the log: Screenshots & Manual

If, like me, you were expecting a list of usage differences between Underscore.js and Lodash, there's a guide for migrating from Underscore.js to Lodash.

Here's the current state of it for posterity:

• Underscore _.any is Lodash _.some
• Underscore _.all is Lodash _.every
• Underscore _.compose is Lodash _.flowRight
• Underscore _.contains is Lodash _.includes
• Underscore _.each doesn’t allow exiting by returning false
• Underscore _.findWhere is Lodash _.find
• Underscore _.flatten is deep by default while Lodash is shallow
• Underscore _.groupBy supports an iteratee that is passed the parameters (value, index, originalArray), while in Lodash, the iteratee for _.groupBy is only passed a single parameter: (value).
• Underscore.js _.indexOf with third parameter undefined is Lodash _.indexOf
• Underscore.js _.indexOf with third parameter true is Lodash _.sortedIndexOf
• Underscore _.indexBy is Lodash _.keyBy
• Underscore _.invoke is Lodash _.invokeMap
• Underscore _.mapObject is Lodash _.mapValues
• Underscore _.max combines Lodash _.max & _.maxBy
• Underscore _.min combines Lodash _.min & _.minBy
• Underscore _.sample combines Lodash _.sample & _.sampleSize
• Underscore _.object combines Lodash _.fromPairs and _.zipObject
• Underscore _.omit by a predicate is Lodash _.omitBy
• Underscore _.pairs is Lodash _.toPairs
• Underscore _.pick by a predicate is Lodash _.pickBy
• Underscore _.pluck is Lodash _.map
• Underscore _.sortedIndex combines Lodash _.sortedIndex & _.sortedIndexOf
• Underscore _.uniq by an iteratee is Lodash _.uniqBy
• Underscore _.where is Lodash _.filter
• Underscore _.isFinite doesn’t align with Number.isFinite
  (e.g. _.isFinite('1') returns true in Underscore.js, but false in Lodash)
• Underscore _.matches shorthand doesn’t support deep comparisons
  (e.g., _.filter(objects, { 'a': { 'b': 'c' } }))
• Underscore = 1.7 & Lodash _.template syntax is
  _.template(string, option)(data)
• Lodash _.memoize caches are Map like objects
• Lodash doesn’t support a context argument for many methods in favor of _.bind
• Lodash supports implicit chaining, lazy chaining, & shortcut fusion
• Lodash split its overloaded _.head, _.last, _.rest, & _.initial out into
  _.take, _.takeRight, _.drop, & _.dropRight
  (i.e. _.head(array, 2) in Underscore.js is _.take(array, 2) in Lodash)

A variation on Steve Wortham's code, to be used nominally with nullable types:

Private Shared Function GetNullable(Of T)(dataobj As Object) As T
    If Convert.IsDBNull(dataobj) Then
        Return Nothing
    Else
        Return CType(dataobj, T)
    End If
End Function

e.g.

mynullable = GetNullable(Of Integer?)(myobj)

You can then query mynullable (e.g., mynullable.HasValue)

Also: git diff master..feature foo

Since git diff foo master:foo doesn't work on directories for me.

i think u miss understand about table relation..

users : scores = 1 : *

just join is not a solution.

is this your intention?

SELECT users.username, avg(scores.point), avg(scores.avg_time)
FROM scores, users
WHERE scores.user_id = users.id
GROUP BY users.username
ORDER BY avg(scores.point) DESC, avg(scores.avg_time)
LIMIT 0, 20

(this query to get each users average point and average avg_time by desc point, asc )avg_time

if you want to get each scores ranking? use left outer join

SELECT users.username, scores.point, scores.avg_time
FROM scores left outer join users on scores.user_id = users.id
ORDER BY scores.point DESC, scores.avg_time
LIMIT 0, 20

I use @see to annotate methods of an interface implementation class where the description of the method is already provided in the javadoc of the interface. When we do that I notice that Eclipse pulls up the interface's documentation even when I am looking up method on the implementation reference during code complete

I have found that often if z-index isn't working its because its parent/siblings don't have a specified z-index.

So if you have:

<div id="1">
    <a id="2" style="z-index:2"></a>
    <div id="3" style="z-index:1"></div>
    <button id="4"></button>
</div>

item #3, or even #4, may be contesting #2 for the click/hover space, though if you set #1 to z-index 0, the siblings who's z-index put them in independant stacks now are in the same stack and will z-index properly.

This has a helpful and fairly humanized description: http://foohack.com/2007/10/top-5-css-mistakes/  

I use with (nolock) hint particularly in SQLServer 2000 databases with high activity. I am not certain that it is needed in SQL Server 2005 however. I recently added that hint in a SQL Server 2000 at the request of the client's DBA, because he was noticing a lot of SPID record locks.

All I can say is that using the hint has NOT hurt us and appears to have made the locking problem solve itself. The DBA at that particular client basically insisted that we use the hint.

By the way, the databases I deal with are back-ends to enterprise medical claims systems, so we are talking about millions of records and 20+ tables in many joins. I typically add a WITH (nolock) hint for each table in the join (unless it is a derived table, in which case you can't use that particular hint)

From http://matplotlib.sourceforge.net/examples/event_handling/pick_event_demo.html :

from matplotlib.pyplot import figure, show
import numpy as npy
from numpy.random import rand


if 1: # picking on a scatter plot (matplotlib.collections.RegularPolyCollection)

    x, y, c, s = rand(4, 100)
    def onpick3(event):
        ind = event.ind
        print('onpick3 scatter:', ind, npy.take(x, ind), npy.take(y, ind))

    fig = figure()
    ax1 = fig.add_subplot(111)
    col = ax1.scatter(x, y, 100*s, c, picker=True)
    #fig.savefig('pscoll.eps')
    fig.canvas.mpl_connect('pick_event', onpick3)

• This recipe draws an annotation on picking a data point: http://scipy-cookbook.readthedocs.io/items/Matplotlib_Interactive_Plotting.html .
• This recipe draws a tooltip, but it requires wxPython: Point and line tooltips in matplotlib?

Shortest (correct) version:

grep -q "something" file; [ $? -eq 0 ] && echo "yes" || echo "no"

can be also written as

grep -q "something" file; test $? -eq 0 && echo "yes" || echo "no"

but you dont need to explicitly test it in this case, so the same with:

grep -q "something" file && echo "yes" || echo "no"

After you connect the UIButton that you want to change its background as an OUtlet to your ViewController.swift file you can use the following:

 yourUIButton.backgroundColor = UIColor.blue

You can log process output using below code:

ProcessStartInfo pinfo = new ProcessStartInfo(item);
pinfo.CreateNoWindow = false;
pinfo.UseShellExecute = true;
pinfo.RedirectStandardOutput = true;
pinfo.RedirectStandardInput = true;
pinfo.RedirectStandardError = true;
pinfo.WindowStyle = System.Diagnostics.ProcessWindowStyle.Normal;
var p = Process.Start(pinfo);
p.WaitForExit();
Process process = Process.Start(new ProcessStartInfo((item + '>' + item + ".txt"))
{
    UseShellExecute = false,
    RedirectStandardOutput = true
});
process.WaitForExit();
string output = process.StandardOutput.ReadToEnd();
if (process.ExitCode != 0) { 
}

Try this:

function createcodes() {

    $('.authors-list tr').each(function () {
        //processing this row
        //how to process each cell(table td) where there is checkbox
        $(this).find('td input:checked').each(function () {

             // it is checked, your code here...
        });
    });
}

= delete is a feature introduce in C++11. As per =delete it will not allowed to call that function.

In detail.

Suppose in a class.

Class ABC{
 Int d;
 Public:
  ABC& operator= (const ABC& obj) =delete
  {

  }
};

While calling this function for obj assignment it will not allowed. Means assignment operator is going to restrict to copy from one object to another.

There are so many ways to do this. The listed ones work great, but here's another way if you have a datetime field:

SELECT [fields] 
FROM [table] 
WHERE timediff(now(), my_datetime_field) < '24:00:00'

timediff() returns a time object, so don't make the mistake of comparing it to 86400 (number of seconds in a day), or your output will be all kinds of wrong.

I had faced the same issue, because the jar library was copied by other Linux user(root), and the logged in user(process) did not have sufficient privilege to read the jar file content.

You need to handle an event on Form1 that is raised as a result of user interaction. For example, if you have a "Settings" button that the user clicks in order to show the settings form (Form2), you should handle the Click event for that button:

private void settingsButton_Click(Object sender, EventArgs e)
{
    // Create a new instance of the Form2 class
    Form2 settingsForm = new Form2();

    // Show the settings form
    settingsForm.Show();
}

In addition to the Show method, you could also choose to use the ShowDialog method. The difference is that the latter shows the form as a modal dialog, meaning that the user cannot interact with the other forms in your application until they close the modal form. This is the same way that a message box works. The ShowDialog method also returns a value indicating how the form was closed.

When the user closes the settings form (by clicking the "X" in the title bar, for example), Windows will automatically take care of closing it.

If you want to close it yourself before the user asks to close it, you can call the form's Close method:

this.Close();

How to implement a SeekBar

Add the SeekBar to your layout

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout
    xmlns:android="http://schemas.android.com/apk/res/android"
    android:orientation="vertical"
    android:layout_width="match_parent"
    android:layout_height="match_parent">

    <TextView
        android:id="@+id/textView"
        android:layout_margin="20dp"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"/>

    <SeekBar
        android:id="@+id/seekBar"
        android:max="100"
        android:progress="50"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"/>

</LinearLayout>

Notes

• max is the highest value that the seek bar can go to. The default is 100. The minimum is 0. The xml min value is only available from API 26, but you can just programmatically convert the 0-100 range to whatever you need for earlier versions.
• progress is the initial position of the slider dot (called a "thumb").
• For a vertical SeekBar use android:rotation="270".

Listen for changes in code

public class MainActivity extends AppCompatActivity {

    TextView tvProgressLabel;

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

        // set a change listener on the SeekBar
        SeekBar seekBar = findViewById(R.id.seekBar);
        seekBar.setOnSeekBarChangeListener(seekBarChangeListener);

        int progress = seekBar.getProgress();
        tvProgressLabel = findViewById(R.id.textView);
        tvProgressLabel.setText("Progress: " + progress);
    }

    SeekBar.OnSeekBarChangeListener seekBarChangeListener = new SeekBar.OnSeekBarChangeListener() {

        @Override
        public void onProgressChanged(SeekBar seekBar, int progress, boolean fromUser) {
            // updated continuously as the user slides the thumb
            tvProgressLabel.setText("Progress: " + progress);
        }

        @Override
        public void onStartTrackingTouch(SeekBar seekBar) {
            // called when the user first touches the SeekBar
        }

        @Override
        public void onStopTrackingTouch(SeekBar seekBar) {
            // called after the user finishes moving the SeekBar
        }
    };
}

Notes

• If you don't need to do any updates while the user is moving the seekbar, then you can just update the UI in onStopTrackingTouch.

In my case, I already had a period(.) and also a comma(,), so what worked for me was to replace the comma(,) with an empty string like below:

parseFloat('3,000.78'.replace(',', '')) 

This is assuming that the amount from the existing database is 3,000.78. The results are: 3000.78 without the initial comma(,).

Very similar to Vishnu's answer but uses the lapply to map all the data to characters then to assign them as the headers. This is really helpful if your data is imported as factors.

DF[] <- lapply(DF, as.character)
colnames(DF) <- DF[1, ]
DF <- DF[-1 ,]

note that that if you have a lot of numeric data or factors you want you'll need to convert them back. In this case it may make sense to store the character data frame, extract the row you want, and then apply it to the original data frame

tempDF <- DF
tempDF[] <- lapply(DF, as.character)
colnames(DF) <- tempDF[1, ]
DF <- DF[-1 ,]
tempDF <- NULL

Those errors :

"CMake Error: CMAKE_C_COMPILER not set, after EnableLanguage

CMake Error: CMAKE_CXX_COMPILER not set, after EnableLanguage"

means you haven't installed mingw32-base.

Go to http://sourceforge.net/projects/mingw/files/latest/download?source=files

and then make sure you select "mingw32-base"

Make sure you set up environment variables correctly in PATH section. "C:\MinGW\bin"

After that open CMake and Select Installation --> Delete Cache.

And click configure button again. I solved the problem this way, hope you solve the problem.

I know this post is ancient but, I found it useful.

It didn't resolve my issue of returning the record with a non empty text field so I thought I would add my solution.

This is the where clause that worked for me.

WHERE xyz LIKE CAST('% %' as text)

This worked for me --

$("#dialog-confirm").html('Do you want to permanently delete this?');
$( "#dialog-confirm" ).dialog({
    resizable: false,
    title:'Confirm',
    modal: true,
    buttons: {
        Cancel: function() {
            $( this ).dialog( "close" );
        },
        OK:function(){
            $('#loading').show();
            $.ajax({
                    type:'post',
                    url:'ajax.php',
                    cache:false,
                    data:{action:'do_something'},
                    async:true,
                    success:function(data){
                        var resp = JSON.parse(data);
                        $("#loading").hide();
                        $("#dialog-confirm").html(resp.msg);
                        $( "#dialog-confirm" ).dialog({
                                resizable: false,
                                title:'Confirm',
                                modal: true,
                                buttons: {
                                    Close: function() {
                                        $( this ).dialog( "close" );
                                    }
                                }
                        });
                    }
                });
        }
    }
}); 

As of PHP 7.1 you can simply do this:

$date = new DateTime( "NOW" );
echo $date->format( "m-d-Y H:i:s.u" );

I removed old AppleWWDRCA, downloaded and installed AppleWWDRCA, but problem remained. I also, checked my distribution and development certificates from Keychain Access, and see below error;

"This certificate has an invalid issuer."

Then,

1. I revoked both development and distribution certificates on member center.
2. Re-created CSR file and add development and distribution certificates from zero, downloaded them, and installed.

This fixed certificate problem.

Since old certificates revoked, existing provisioning profiles become invalid. To fix this;

1. On member center, opened provisioning profiles.
2. Opened profile detail by clicking "Edit", checked certificate from the list, and clicked "Generate" button.
3. Downloaded and installed both development and distribution profiles.

I hope this helps.

Go means, whatever SQL statements are written before it and after any earlier GO, will go to SQL server for processing.

Select * from employees;
GO    -- GO 1

update employees set empID=21 where empCode=123;
GO    -- GO 2

In the above example, statements before GO 1 will go to sql sever in a batch and then any other statements before GO 2 will go to sql server in another batch. So as we see it has separated batches.

What you have is a string representing a JSON serialized javascript object. You need to deserialize it back a javascript object before being able to loop through its properties. Otherwise you will be looping through each individual character of this string.

var resultJSON = '{ "key1" : "watevr1", "key2" : "watevr2", "key3" : "watevr3" }';
    var result = $.parseJSON(resultJSON);
    $.each(result, function(k, v) {
        //display the key and value pair
        alert(k + ' is ' + v);
    });

or simply:

arr.forEach(function (val, index, theArray) {
    //do stuff
});

In Angular 2 you can do 3 types of bindings:

• [property]="expression" -> Any html property can link to an
  expression. In this case, if expression changes property will update, but this doesn't work the other way.
• (event)="expression" -> When event activates execute expression.
• [(ngModel)]="property" -> Binds the property from js (or ts) to html. Any update on this property will be noticeable everywhere.

An expression can be a value, an attribute or a method. For example: '4', 'controller.var', 'getValue()'

Here is a solution usings lists as stacks in python :

def isPalindromicNum(n):
    """
        is 'n' a palindromic number?
    """
    ns = list(str(n))
    for n in ns:
        if n != ns.pop():
            return False
    return True

popping the stack only considers the rightmost side of the number for comparison and it fails fast to reduce checks

Don't forget that the generated Javadoc for a class will include a list of known subclasses (and for interfaces, known implementing classes).

I know this is an old and answered question and I'm not looking for votes I just want to add an extra little thing that I think might help newcomers.

yes appendChild is a DOM method and append is JQuery method but practically the key difference is that appendChild takes a node as a parameter by that I mean if you want to add an empty paragraph to the DOM you need to create that p element first

var p = document.createElement('p')

then you can add it to the DOM whereas JQuery append creates that node for you and adds it to the DOM right away whether it's a text element or an html element or a combination!

$('p').append('<span> I have been appended </span>');

As Marc says, you run it exactly like you would from the command line. See Creating SQL Server Agent Jobs on MSDN.

In case that you have Ubuntu in your machine, the following steps will help you:

1. Check first in your php testing file if you have soap (client / server)or not by using phpinfo(); and check results in the browser. In case that you have it, it will seems like the following image ( If not go to step 2 ):

2. Open your terminal and paste: sudo apt-get install php-soap.

3. Restart your apache2 server in terminal : service apache2 restart.

4. To check use your php test file again to be seems like mine in step 1.

I think best approach until Angular team add this feature to cli is first create angular (ng new something) in other place and then add what you want to delete. Using git to check witch files are changed or added by angular cli. then you can revert that changes. Be careful of untracked files from .gitignore.

In Excel, the substring function is called MID function, and indexOf is called FIND for case-sensitive location and SEARCH function for non-case-sensitive location. For the first portion of your text parsing the LEFT function may also be useful.

See all the text functions here: Text Functions (reference).

This gives error:

int len;
scanf("%d",&len);
char str[len]="";

This also gives error:

int len=5;
char str[len]="";

But this works fine:

int len=5;
char str[len]; //so the problem lies with assignment not declaration

You need to put value in the following way:

str[0]='a';
str[1]='b'; //like that; and not like str="ab";

List<String> names = Arrays.asList("2","@2234","21","11");

You can use .resize() to get every time the width/height actually changes, like this:

$(window).resize(function() {
  //resize just happened, pixels changed
});

You can view a working demo here, it takes the new height/width values and updates them in the page for you to see. Remember the event doesn't really start or end, it just "happens" when a resize occurs...there's nothing to say another one won't happen.

Edit: By comments it seems you want something like a "on-end" event, the solution you found does this, with a few exceptions (you can't distinguish between a mouse-up and a pause in a cross-browser way, the same for an end vs a pause). You can create that event though, to make it a bit cleaner, like this:

$(window).resize(function() {
    if(this.resizeTO) clearTimeout(this.resizeTO);
    this.resizeTO = setTimeout(function() {
        $(this).trigger('resizeEnd');
    }, 500);
});

You could have this is a base file somewhere, whatever you want to do...then you can bind to that new resizeEnd event you're triggering, like this:

$(window).bind('resizeEnd', function() {
    //do something, window hasn't changed size in 500ms
});

You can see a working demo of this approach here ?

Those are by no means the same. The first will simply send you to whatever URL you have assigned to window.location.href (in the same window you're currently in). The second makes a GET AJAX request.

Try this page: http://www.codebelt.com/jquery/open-new-browser-window-with-jquery-custom-size/

It gives a great example on how to open a new window*.

If you wish to use raw javascript then this is what you're looking for:

window.open(URL,name,specs,replace)

1) Add any remote repositories you want to compare:

git remote add foobar git://github.com/user/foobar.git

2) Update your local copy of a remote:

git fetch foobar

Fetch won't change your working copy.

3) Compare any branch from your local repository to any remote you've added:

git diff master foobar/master

Some additional advice for Windows(10) users:

1. If you are using Anaconda Prompt/PowerShell for the first time, type "Anaconda" in the search field of your Windows task bar and you will see the suggested software.
2. Make sure to open the Anaconda prompt as administrator.
3. Always navigate to your user directory or the directory with your Jupyter Notebook files first before running the command. Otherwise you might end up somewhere in your system files and be confused by an unfamiliar file tree.

The correct way to open Jupyter notebook with new data limit from the Anaconda Prompt on my own Windows 10 PC is:

(base) C:\Users\mobarget\Google Drive\Jupyter Notebook>jupyter notebook --NotebookApp.iopub_data_rate_limit=1.0e10

Had a similar issue. But it is important to understand the root cause and it may vary for different use cases.

Scenario 1
You are trying to decrypt a value which was not encoded correctly in the first place.

byte[] encryptedBytes = Base64.decodeBase64(encryptedBase64String);

If the String is misconfigured for certain reason or has not been encoded correctly, you would see the error " Input length must be multiple of 16 when decrypting with padded cipher"

Scenario 2
Now if by any chance you are using this encoded string in url (trying to pass in the base64Encoded value in url, it will fail. You should do URLEncoding and then pass in the token, it will work.

Scenario 3
When integrating with one of the vendors, we found that we had to do encryption of Base64 using URLEncoder but then we need not decode it because it was done internally by the Vendor

Old question but none of the answers worked for me.

Since all the answers allow NaN to be included, I thought I'd add that if you want to quickly cast an array of mixed values to numbers you can do.

var a = "1,2,3,4,foo,bar";

var b = a.split(',');

var result = b.map(_=>_|0) // Floors the number (32-bit signed integer) so this wont work if you need all 64 bits.

// or b.map(_=>_||0) if you know your array is just numbers but may include NaN.

#collect is actually an alias for #map. That means the two methods can be used interchangeably, and effect the same behavior.

Apache is an HTTP web server which serve as HTTP.

Apache Tomcat is a java servlet container. It features same as web server but is customized to execute java servlet and JSP pages.

Since the API you're calling is async, the Parallel.ForEach version doesn't make much sense. You shouldnt use .Wait in the WaitAll version since that would lose the parallelism Another alternative if the caller is async is using Task.WhenAll after doing Select and ToArray to generate the array of tasks. A second alternative is using Rx 2.0

Domain Driven Design is a methodology and process prescription for the development of complex systems whose focus is mapping activities, tasks, events, and data within a problem domain into the technology artifacts of a solution domain.

The emphasis of Domain Driven Design is to understand the problem domain in order to create an abstract model of the problem domain which can then be implemented in a particular set of technologies. Domain Driven Design as a methodology provides guidelines for how this model development and technology development can result in a system that meets the needs of the people using it while also being robust in the face of change in the problem domain.

The process side of Domain Driven Design involves the collaboration between domain experts, people who know the problem domain, and the design/architecture experts, people who know the solution domain. The idea is to have a shared model with shared language so that as people from these two different domains with their two different perspectives discuss the solution they are actually discussing a shared knowledge base with shared concepts.

The lack of a shared problem domain understanding between the people who need a particular system and the people who are designing and implementing the system seems to be a core impediment to successful projects. Domain Driven Design is a methodology to address this impediment.

It is more than having an object model. The focus is really about the shared communication and improving collaboration so that the actual needs within the problem domain can be discovered and an appropriate solution created to meet those needs.

Domain-Driven Design: The Good and The Challenging provides a brief overview with this comment:

DDD helps discover the top-level architecture and inform about the mechanics and dynamics of the domain that the software needs to replicate. Concretely, it means that a well done DDD analysis minimizes misunderstandings between domain experts and software architects, and it reduces the subsequent number of expensive requests for change. By splitting the domain complexity in smaller contexts, DDD avoids forcing project architects to design a bloated object model, which is where a lot of time is lost in working out implementation details — in part because the number of entities to deal with often grows beyond the size of conference-room white boards.

Also see this article Domain Driven Design for Services Architecture which provides a short example. The article provides the following thumbnail description of Domain Driven Design.

Domain Driven Design advocates modeling based on the reality of business as relevant to our use cases. As it is now getting older and hype level decreasing, many of us forget that the DDD approach really helps in understanding the problem at hand and design software towards the common understanding of the solution. When building applications, DDD talks about problems as domains and subdomains. It describes independent steps/areas of problems as bounded contexts, emphasizes a common language to talk about these problems, and adds many technical concepts, like entities, value objects and aggregate root rules to support the implementation.

Martin Fowler has written a number of articles in which Domain Driven Design as a methodology is mentioned. For instance this article, BoundedContext, provides an overview of the bounded context concept from Domain Driven Development.

In those younger days we were advised to build a unified model of the entire business, but DDD recognizes that we've learned that "total unification of the domain model for a large system will not be feasible or cost-effective" 1. So instead DDD divides up a large system into Bounded Contexts, each of which can have a unified model - essentially a way of structuring MultipleCanonicalModels.

Above method is working, but here are more realistic slide up and slide down animations from the top of the screen.

Just create these two animations under the anim folder

slide_down.xml

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

    <translate
        android:duration="200"
        android:fromYDelta="-100%"
        android:toYDelta="0" />
</set> 

slide_up.xml

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

    <translate
        android:duration="200"
        android:fromYDelta="0"
        android:toYDelta="-100%" />
</set>

Load animation in java class like this

imageView.startAnimation(AnimationUtils.loadAnimation(getContext(),R.anim.slide_up));
imageView.startAnimation(AnimationUtils.loadAnimation(getContext(),R.anim.slide_down));

You can use exec command to redirect all stdout/stderr output of any commands later.

sample script:

exec 2> your_file2 > your_file1
your other commands.....

Go for the full installation of Git for windows (with Unix tool), and bison and flex would come with it in the bin folder.

As of Git v2.23.0 (August 2019), git switch is preferred over git checkout when you’re simply switching branches/tags. I’m guessing they did this since git checkout had two functions: for switching branches and for restoring files. So in v2.23.0, they added two new commands, git switch, and git restore, to separate those concerns. I would predict at some point in the future, git checkout will be deprecated.

To switch to a normal branch, use git switch <branch-name>. To switch to a commit-like object, including single commits and tags, use git switch --detach <commitish>, where <commitish> is the tag name or commit number.

The --detach option forces you to recognize that you’re in a mode of “inspection and discardable experiments”. To create a new branch from the commitish you’re switching to, use git switch -c <new-branch> <start-point>.

You can add it by appending a Series to the dataframe as follows. I am assuming by blank you mean you want to add a row containing only "Nan". You can first create a Series object with Nan. Make sure you specify the columns while defining 'Series' object in the -Index parameter. The you can append it to the DF. Hope it helps!

from numpy import nan as Nan
import pandas as pd

>>> df1 = pd.DataFrame({'A': ['A0', 'A1', 'A2', 'A3'],
...                     'B': ['B0', 'B1', 'B2', 'B3'],
...                     'C': ['C0', 'C1', 'C2', 'C3'],
...                     'D': ['D0', 'D1', 'D2', 'D3']},
...                     index=[0, 1, 2, 3])

>>> s2 = pd.Series([Nan,Nan,Nan,Nan], index=['A', 'B', 'C', 'D'])
>>> result = df1.append(s2)
>>> result
     A    B    C    D
0   A0   B0   C0   D0
1   A1   B1   C1   D1
2   A2   B2   C2   D2
3   A3   B3   C3   D3
4  NaN  NaN  NaN  NaN

Sets don't have a join method but you can use str.join instead.

', '.join(set_3)

The str.join method will work on any iterable object including lists and sets.

Note: be careful about using this on sets containing integers; you will need to convert the integers to strings before the call to join. For example

set_4 = {1, 2}
', '.join(str(s) for s in set_4)

Create a branch where you are, then switch to master and merge it:

git branch my-temporary-work
git checkout master
git merge my-temporary-work

Thou the above answer is widely accepted and well documented, I found some of the reason to post my answer here :-

    doNothing().when(InternalUtils.class); //This is the preferred way
                                           //to mock static void methods.
    InternalUtils.sendEmail(anyString(), anyString(), anyString(), anyString());

Here, I dont understand why we are calling InternalUtils.sendEmail ourself. I will explain in my code why we don't need to do that.

mockStatic(Internalutils.class);

So, we have mocked the class which is fine. Now, lets have a look how we need to verify the sendEmail(/..../) method.

@PrepareForTest({InternalService.InternalUtils.class})
@RunWith(PowerMockRunner.class)
public class InternalServiceTest {

    @Mock
    private InternalService.Order order;

    private InternalService internalService;

    @Before
    public void setup() {
        MockitoAnnotations.initMocks(this);
        internalService = new InternalService();
    }

    @Test
    public void processOrder() throws Exception {

        Mockito.when(order.isSuccessful()).thenReturn(true);
        PowerMockito.mockStatic(InternalService.InternalUtils.class);

        internalService.processOrder(order);

        PowerMockito.verifyStatic(times(1));
        InternalService.InternalUtils.sendEmail(anyString(), any(String[].class), anyString(), anyString());
    }

}

These two lines is where the magic is, First line tells the PowerMockito framework that it needs to verify the class it statically mocked. But which method it need to verify ?? Second line tells which method it needs to verify.

PowerMockito.verifyStatic(times(1));
InternalService.InternalUtils.sendEmail(anyString(), any(String[].class), anyString(), anyString());

This is code of my class, sendEmail api twice.

public class InternalService {

    public void processOrder(Order order) {
        if (order.isSuccessful()) {
            InternalUtils.sendEmail("", new String[1], "", "");
            InternalUtils.sendEmail("", new String[1], "", "");
        }
    }

    public static class InternalUtils{

        public static void sendEmail(String from, String[]  to, String msg, String body){

        }

    }

    public class Order{

        public boolean isSuccessful(){
            return true;
        }

    }

}

As it is calling twice you just need to change the verify(times(2))... that's all.

Here I have a solution that avoid multiple requests, for loops and old document removal.

You can easily create a new idea manually using something like:_id:ObjectId() But knowing Mongo will automatically assign an _id if missing, you can use aggregate to create a $project containing all the fields of your document, but omit the field _id. You can then save it with $out

So if your document is:

{
"_id":ObjectId("5b5ed345cfbce6787588e480"),
"title": "foo",
"description": "bar"
}

Then your query will be:

    db.getCollection('myCollection').aggregate([
        {$match:
             {_id: ObjectId("5b5ed345cfbce6787588e480")}
        }        
        {$project:
            {
             title: '$title',
             description: '$description'             
            }     
        },
        {$out: 'myCollection'}
    ])

<script type="text/javascript">
jQuery(function () {
    var container = jQuery("\#content");
    jQuery(container)
     .kendoGrid({
         selectable: "single row",
         dataSource: new kendo.data.DataSource({
             transport: {
                 read: {
                     url: "@Url.Action("GetMsgDetails", "OutMessage")" + "?msgId=" + msgId,
                     dataType: "json",
                 },
             },
             batch: true,
         }),
         editable: "popup",
         columns: [
            { field: "Id", title: "Id", width: 250, hidden: true },
            { field: "Data", title: "Message Body", width: 100 },
           { field: "mobile", title: "Mobile Number", width: 100 },
         ]
     });
});

You have an option to define collation order at the time of defining your table. If you define a case-sensitive order, your LIKE operator will behave in a case-sensitive way; if you define a case-insensitive collation order, the LIKE operator will ignore character case as well:

CREATE TABLE Test (
    CI_Str VARCHAR(15) COLLATE Latin1_General_CI_AS -- Case-insensitive
,   CS_Str VARCHAR(15) COLLATE Latin1_General_CS_AS -- Case-sensitive
);

Here is a quick demo on sqlfiddle showing the results of collation order on searches with LIKE.

In my case the flask version was only visible under so I had to go to C:\Users\\AppData\Local\flask\venv\Scripts>pip freeze --local

You could use CSS to do that, but it wouldn't be supported in IE8-. You can use some site like http://borderradius.com to come up with actual CSS you'd use, which would look something like this (again, depending on how many browsers you're trying to support):

-webkit-border-radius: 5px;
-moz-border-radius: 5px;
border-radius: 5px;

A short traverse could be given too using the sub-expression operator $( ), which returns the result of one or more statements.

$hash = @{ a = 1; b = 2; c = 3}

forEach($y in $hash.Keys){
    Write-Host "$y -> $($hash[$y])"
}

Result:

a -> 1
b -> 2
c -> 3

To validate phone numbers for a specific region in Android, use libPhoneNumber from Google, and the following code as an example:

public boolean isPhoneNumberValid(String phoneNumber, String countryCode)
{
    //NOTE: This should probably be a member variable.
    PhoneNumberUtil phoneUtil = PhoneNumberUtil.getInstance();

    try 
    {
        PhoneNumber numberProto = phoneUtil.parse(phoneNumber, countryCode);
        return phoneUtil.isValidNumber(numberProto);
    } 
    catch (NumberParseException e) 
    {
        System.err.println("NumberParseException was thrown: " + e.toString());
    }

    return false;
}

@Ali Shakiba your code needs some modification. Error part:

for (int i = 0; i < myArray.length; i++) {
     myStatement.setString(i, myArray[i][1]);
     myStatement.setString(i, myArray[i][2]);
}

Updated code:

String myArray[][] = {
    {"1-1", "1-2"},
    {"2-1", "2-2"},
    {"3-1", "3-2"}
};

StringBuffer mySql = new StringBuffer("insert into MyTable (col1, col2) values (?, ?)");

for (int i = 0; i < myArray.length - 1; i++) {
    mySql.append(", (?, ?)");
}

mysql.append(";"); //also add the terminator at the end of sql statement
myStatement = myConnection.prepareStatement(mySql.toString());

for (int i = 0; i < myArray.length; i++) {
    myStatement.setString((2 * i) + 1, myArray[i][1]);
    myStatement.setString((2 * i) + 2, myArray[i][2]);
}

myStatement.executeUpdate();

examples from doc... ;)

because you rely on this context:

• which is lost when the function is invoked by .throw
• there’s no way for it to know what this is supposed to be

you have to use one of these options:

• wrap the method or function call inside of another function

• bind the context

  // wrap the method or function call inside of another function
  expect(function () { cat.meow(); }).to.throw();  // Function expression
  expect(() => cat.meow()).to.throw();             // ES6 arrow function
  
  // bind the context
  expect(cat.meow.bind(cat)).to.throw();           // Bind
  

php artisan dump-autoload was deprecated on Laravel 5, so you need to use composer dump-autoload

Personally, window.postMessage is the most reliable way that I've found for modern browsers. You do have to do a slight bit more work to make sure you're not leaving yourself open to XSS attacks, but it's a reasonable tradeoff.

There are also several plugins for the popular Javascript toolkits out there that wrap window.postMessage that provide similar functionality to older browsers using the other methods discussed above.

To ensure that a Semaphore is binary you just need to make sure you pass in the number of permits as 1 when creating the semaphore. The Javadocs have a bit more explanation.

Use this:

os.path.splitext("name.fasta")[0]+".aln"

And here is how the above works:

The splitext method separates the name from the extension creating a tuple:

os.path.splitext("name.fasta")

the created tuple now contains the strings "name" and "fasta". Then you need to access only the string "name" which is the first element of the tuple:

os.path.splitext("name.fasta")[0]

And then you want to add a new extension to that name:

os.path.splitext("name.fasta")[0]+".aln"

We can declare static methods with same signature in subclass, but it is not considered overriding as there won’t be any run-time polymorphism.Because since all static members of a class are loaded at the time of class loading so it decide at compile time(overriding at run time) Hence the answer is ‘No’.

This is a lot simpler with .slideToggle():

jQuery('.class1 a').click( function() {
  $(this).next('.class2').slideToggle();
});

EDIT: made it .next instead of .siblings

http://www.mredesign.com/demos/jquery-effects-1/

You can also add cookie's to remember where you're at...

http://c.hadcoleman.com/2008/09/jquery-slide-toggle-with-cookie/

You can also try this.

$('#datepickerID').val();

This is the simplest way.

Although this is the accepted answer, toto_tico's answer below is better :)

Try making the onclick js use 'return' to ensure the desired return value gets used...

<button type="button" value="click me" onclick="return check_me();" />

For the links which contains common url have to console in a variable. Then attempt it sequentially.

webelements allLinks=driver.findelements(By.xpath("//a[contains(@href,'http://122.11.38.214/dl/appdl/application/apk')]"));
int linkCount=allLinks.length();
for(int i=0; <linkCount;i++)
{
    driver.findelement(allLinks[i]).click();
}

I just had a situation where I had to find the max of 4 complex selects within an update. With this approach you can have as many as you like!

You can also replace the numbers with aditional selects

select max(x)
 from (
 select 1 as 'x' union
 select 4 as 'x' union
 select 3 as 'x' union
 select 2 as 'x' 
 ) a

More complex usage

 @answer = select Max(x)
           from (
                select @NumberA as 'x' union
                select @NumberB as 'x' union
                select @NumberC as 'x' union
                select (
                       Select Max(score) from TopScores
                       ) as 'x' 
     ) a

I'm sure a UDF has better performance.

You want matplotlib.pcolor:

import numpy as np 
from pandas import DataFrame
import matplotlib.pyplot as plt

index = ['aaa', 'bbb', 'ccc', 'ddd', 'eee']
columns = ['A', 'B', 'C', 'D']
df = DataFrame(abs(np.random.randn(5, 4)), index=index, columns=columns)

plt.pcolor(df)
plt.yticks(np.arange(0.5, len(df.index), 1), df.index)
plt.xticks(np.arange(0.5, len(df.columns), 1), df.columns)
plt.show()

This gives:

I'm Using Xampp and Laravel 5.8 in Windows 10, and i've been like this before. When i got this problem, My XAMPP is no have Password Then I tried to delete some codes in config>database.php

'password' => env('DB_PASSWORD', ''),

And in .env

DB_PASSWORD=SECRET

the Problem is solved
