As a generic answer, not specifically directed at this task: In many cases, you can significantly speed up any program by making improvements at a high level. Like calculating data once instead of multiple times, avoiding unnecessary work completely, using caches in the best way, and so on. These things are much easier to do in a high level language.

Writing assembler code, it is possible to improve on what an optimising compiler does, but it is hard work. And once it's done, your code is much harder to modify, so it is much more difficult to add algorithmic improvements. Sometimes the processor has functionality that you cannot use from a high level language, inline assembly is often useful in these cases and still lets you use a high level language.

In the Euler problems, most of the time you succeed by building something, finding why it is slow, building something better, finding why it is slow, and so on and so on. That is very, very hard using assembler. A better algorithm at half the possible speed will usually beat a worse algorithm at full speed, and getting the full speed in assembler isn't trivial.

Use FileSaver.js. It supports Chrome, Edge, Firefox, and IE 10+ (and probably IE < 10 with a few "polyfills" - see Note 4). FileSaver.js implements the saveAs() FileSaver interface in browsers that do not natively support it:
     https://github.com/eligrey/FileSaver.js

Minified version is really small at < 2.5KB, gzipped < 1.2KB.

Usage:

/* TODO: replace the blob content with your byte[] */
var blob = new Blob([yourBinaryDataAsAnArrayOrAsAString], {type: "application/octet-stream"});
var fileName = "myFileName.myExtension";
saveAs(blob, fileName);

You might need Blob.js in some browsers (see Note 3). Blob.js implements the W3C Blob interface in browsers that do not natively support it. It is a cross-browser implementation:
     https://github.com/eligrey/Blob.js

Consider StreamSaver.js if you have files larger than blob's size limitations.

You are calling the ready function before the jQuery JavaScript is included. Reference jQuery first.

Here is a list of examples for sending cookies - https://github.com/andriichuk/php-curl-cookbook#cookies

$curlHandler = curl_init();

curl_setopt_array($curlHandler, [
CURLOPT_URL => 'https://httpbin.org/cookies',
CURLOPT_RETURNTRANSFER => true,

CURLOPT_COOKIEFILE  => $cookieFile,
CURLOPT_COOKIE => 'foo=bar;baz=foo',

/**
 * Or set header
 * CURLOPT_HTTPHEADER => [
       'Cookie: foo=bar;baz=foo',
   ]
 */
]);

$response = curl_exec($curlHandler);
curl_close($curlHandler);

echo $response;

Underscore. Not space.

$_SERVER['HTTP_REFERER']

You have most of the code…

CURLOPT_HTTPHEADER for curl_setopt() takes an array with each header as an element. You have one element with multiple headers.

You also need to add the Authorization header to your $header array.

$header = array();
$header[] = 'Content-length: 0';
$header[] = 'Content-type: application/json';
$header[] = 'Authorization: OAuth SomeHugeOAuthaccess_tokenThatIReceivedAsAString';

You need to do two things:

1. Rename and re-order the factor levels before the plot
2. Rename the title of each legend to the same title

The code:

dtt$model <- factor(dtt$model, levels=c("mb", "ma", "mc"), labels=c("MBB", "MAA", "MCC"))

library(ggplot2)
ggplot(dtt, aes(x=year, y=V, group = model, colour = model, ymin = lower, ymax = upper)) +
  geom_ribbon(alpha = 0.35, linetype=0)+ 
  geom_line(aes(linetype=model), size = 1) +       
  geom_point(aes(shape=model), size=4)  +      
  theme(legend.position=c(.6,0.8)) +
  theme(legend.background = element_rect(colour = 'black', fill = 'grey90', size = 1, linetype='solid')) +
  scale_linetype_discrete("Model 1") +
  scale_shape_discrete("Model 1") +
  scale_colour_discrete("Model 1")

However, I think this is really ugly as well as difficult to interpret. It's far better to use facets:

ggplot(dtt, aes(x=year, y=V, group = model, colour = model, ymin = lower, ymax = upper)) +
  geom_ribbon(alpha=0.2, colour=NA)+ 
  geom_line() +       
  geom_point()  +      
  facet_wrap(~model)

If we want to add custom HTTP headers to a POST request, we must pass them through a dictionary to the headers parameter.

Here is an example with a non-empty body and headers:

import requests
import json

url = 'https://somedomain.com'
body = {'name': 'Maryja'}
headers = {'content-type': 'application/json'}

r = requests.post(url, data=json.dumps(body), headers=headers)

Source

The problem is in the refresh token:

[refresh_token] => 1\/lov250YQTMCC9LRQbE6yMv-FiX_Offo79UXimV8kvwY

When a string with a '/' gets json encoded, It is escaped with a '\', hence you need to remove it.

The refresh token in your case should be:

1/lov250YQTMCC9LRQbE6yMv-FiX_Offo79UXimV8kvwY

What i'm assuming you've done is that you've printed the json string which google sent back and copied and pasted the token into your code because if you json_decode it then it will correctly remove the '\' for you!

You probably want to make a range query, for example, all items created after a given date:

db.gpsdatas.find({"createdAt" : { $gte : new ISODate("2012-01-12T20:15:31Z") }});

I'm using $gte (greater than or equals), because this is often used for date-only queries, where the time component is 00:00:00.

If you really want to find a date that equals another date, the syntax would be

db.gpsdatas.find({"createdAt" : new ISODate("2012-01-12T20:15:31Z") });

Simple sulution

jar {
    manifest {
        attributes 'Main-Class': 'cova2.Main'
    } 
    doFirst {
        from { configurations.runtime.collect { it.isDirectory() ? it : zipTree(it) } }
    }
}

const is for compile-time constants. You could just make it static readonly, but that would only apply to the METRICS variable itself (which should typically be Metrics instead, by .NET naming conventions). It wouldn't make the list immutable - so someone could call METRICS.Add("shouldn't be here");

You may want to use a ReadOnlyCollection<T> to wrap it. For example:

public static readonly IList<String> Metrics = new ReadOnlyCollection<string>
    (new List<String> { 
         SourceFile.LoC, SourceFile.McCabe, SourceFile.NoM,
         SourceFile.NoA, SourceFile.FanOut, SourceFile.FanIn, 
         SourceFile.Par, SourceFile.Ndc, SourceFile.Calls });

ReadOnlyCollection<T> just wraps a potentially-mutable collection, but as nothing else will have access to the List<T> afterwards, you can regard the overall collection as immutable.

(The capitalization here is mostly guesswork - using fuller names would make them clearer, IMO.)

Whether you declare it as IList<string>, IEnumerable<string>, ReadOnlyCollection<string> or something else is up to you... if you expect that it should only be treated as a sequence, then IEnumerable<string> would probably be most appropriate. If the order matters and you want people to be able to access it by index, IList<T> may be appropriate. If you want to make the immutability apparent, declaring it as ReadOnlyCollection<T> could be handy - but inflexible.

Jerryf's answer is fine, except for one flaw.

The onload event should be set before the src. Sometimes the src can be loaded instantly and never fire the onload event.

(Like Totty.js pointed out.)

var canvas = document.getElementById("c");
var ctx = canvas.getContext("2d");

var image = new Image();
image.onload = function() {
    ctx.drawImage(image, 0, 0);
};
image.src = "data:image/  png;base64,iVBORw0KGgoAAAANSUhEUgAAAAUAAAAFCAIAAAACDbGyAAAAAXNSR0IArs4c6QAAAAlwSFlzAAALEwAACxMBAJqcGAAAAAd0SU1FB9oMCRUiMrIBQVkAAAAZdEVYdENvbW1lbnQAQ3JlYXRlZCB3aXRoIEdJTVBXgQ4XAAAADElEQVQI12NgoC4AAABQAAEiE+h1AAAAAElFTkSuQmCC";

While the git fetch command will fetch down all the changes on the server that you don’t have yet, it will not modify your working directory at all. It will simply get the data for you and let you merge it yourself. However, there is a command called git pull which is essentially a git fetch immediately followed by a git merge in most cases.

If you really need to encode UTF-8, you can try prepending the unicode byte order mark. I have no idea how widespread the support for this method is, but ZXing at least appears to support it: http://code.google.com/p/zxing/issues/detail?id=103

I've been reading up on QR Mode recently, and I think I've seen the same practice mentioned elsewhere, but I've not the foggiest where.

I would base my answer on how often the function is called.

If it is an init function that is only ever called once then let it take 10 parms or more, who cares.

If it is called a bunch of times per frame then I tend to make a structure and just pass a pointer to it since that tends to be faster ( assuming that you are not rebuilding the struct every time as well ).

The formal parameters for a function are listed in the function declaration and are used in the body of the function definition. A formal parameter (of any sort) is a kind of blank or placeholder that is filled in with something when the function is called.

An argument is something that is used to fill in a formal parameter. When you write down a function call, the arguments are listed in parentheses after the function name. When the function call is executed, the arguments are plugged in for the formal parameters.

The terms call-by-value and call-by-reference refer to the mechanism that is used in the plugging-in process. In the call-by-value method only the value of the argument is used. In this call-by-value mechanism, the formal parameter is a local variable that is initialized to the value of the corresponding argument. In the call-by-reference mechanism the argument is a variable and the entire variable is used. In the call- by-reference mechanism the argument variable is substituted for the formal parameter so that any change that is made to the formal parameter is actually made to the argument variable.

Here is the answer.

string result = String.Empty;

var list = new[]
{ 
    new { Number = 10, Name = "Smith" },
    new { Number = 10, Name = "John" } 
}.ToList();

foreach (var item in list)
{
    result += String.Format("Name={0}, Number={1}\n", item.Name, item.Number);
}

MessageBox.Show(result);

None of the answers is wrong, however a little confusing maybe.

• When querying single values/rows it's always bad practise to use NOLOCK -- you probably never want to display incorrect information or maybe even take any action on incorrect data.
• When displaying rough statistical information, NOLOCK can be very useful. Take SO as an example: It would be nonsense to take locks to read the exact number of views of a question, or the exact number of questions for a tag. Nobody cares if you incorrectly state 3360 questions tagged with "sql-server" now, and because of a transaction rollback, 3359 questions one second later.

We can find file name below code:

File file =new File(Path);
String filename=file.getName();

UPSERT support in SQLite! UPSERT syntax was added to SQLite with version 3.24.0 (pending) !

UPSERT is a special syntax addition to INSERT that causes the INSERT to behave as an UPDATE or a no-op if the INSERT would violate a uniqueness constraint. UPSERT is not standard SQL. UPSERT in SQLite follows the syntax established by PostgreSQL.

alternatively:

Another completely different way of doing this is: In my application I set my in memory rowID to be long.MaxValue when I create the row in memory. (MaxValue will never be used as an ID you will won't live long enough.... Then if rowID is not that value then it must already be in the database so needs an UPDATE if it is MaxValue then it needs an insert. This is only useful if you can track the rowIDs in your app.

You can convert Map to JSON using Jackson as follows:

Map<String,String> payload = new HashMap<>();
payload.put("key1","value1");
payload.put("key2","value2");

String json = new ObjectMapper().writeValueAsString(payload);
System.out.println(json);

Maybe cheating a little, but the MAC Address of a machines Ethernet adapter rarely changes without the motherboard changing these days.

I don't like setting CLASSPATH. CLASSPATH is a global variable and as such it is evil:

• If you modify it in one script, suddenly some java programs will stop working.
• If you put there the libraries for all the things which you run, and it gets cluttered.
• You get conflicts if two different applications use different versions of the same library.
• There is no performance gain as libraries in the CLASSPATH are not shared - just their name is shared.
• If you put the dot (.) or any other relative path in the CLASSPATH that means a different thing in each place - that will cause confusion, for sure.

Therefore the preferred way is to set the classpath per each run of the jvm, for example:

java -Xmx500m -cp ".:../somejar.jar:../mysql-connector-java-5.1.6-bin.jar"    "folder.subfolder../dit1/some.xml

If it gets long the standard procedure is to wrap it in a bash or batch script to save typing.

In malfaux's answer '^' and '$' has been used to detect the beginning and the end of the text.
These are usually used to detect the beginning and the end of a line.
However this may be the correct way in this case.
But if you wish to match an exact word the more elegant way is to use '\b'. In this case following pattern will match the exact phrase'123456'.

/\b123456\b/

DialogResult result = MessageBox.Show("Do you want to save changes?", "Confirmation", MessageBoxButtons.YesNoCancel);
if(result == DialogResult.Yes)
{ 
    //...
}
else if (result == DialogResult.No)
{ 
    //...
}
else
{
    //...
} 

Make sure that both the chromedriver and google-chrome executable have execute permissions

Since this question is gaining lots of views and this was the accepted answer, I felt the need to add the following disclaimer:

This answer was specific to the OP's question (Which had the width set in the examples). While it works, it requires you to have a width on each of the elements, the image and the paragraph. Unless that is your requirement, I recommend using Joe Conlin's solution which is posted as another answer on this question.

The span element is an inline element, you can't change its width in CSS.

You can add the following CSS to your span so you will be able to change its width.

display: block;

Another way, which usually makes more sense, is to use a <p> element as a parent for your <span>.

<li id="CN2787">
  <img class="fav_star" src="images/fav.png">
  <p>
     <span>Text, text and more text</span>
  </p>
</li>

Since <p> is a block element, you can set its width using CSS, without having to change anything.

But in both cases, since you have a block element now, you will need to float the image so that your text doesn't all go below your image.

li p{width: 100px; margin-left: 20px}
.fav_star {width: 20px;float:left}

P.S. Instead of float:left on the image, you can also put float:right on li p but in that case, you will also need text-align:left to realign the text correctly.

P.S.S. If you went ahead with the first solution of not adding a <p> element, your CSS should look like so:

li span{width: 100px; margin-left: 20px;display:block}
.fav_star {width: 20px;float:left}

If you ignore the characteristics of both languages, how do you define "SPEED"? Which features should be in your benchmark and which do you want to omit?

For example:

• Does it count when Java executes an empty loop faster than Python?
• Or is Python faster when it notices that the loop body is empty, the loop header has no side effects and it optimizes the whole loop away?
• Or is that "a language characteristic"?
• Do you want to know how many bytecodes each language can execute per second?
• Which ones? Only the fast ones or all of them?
• How do you count the Java VM JIT compiler which turns bytecode into CPU-specific assembler code at runtime?
• Do you include code compilation times (which are extra in Java but always included in Python)?

Conclusion: Your question has no answer because it isn't defined what you want. Even if you made it more clear, the question will probably become academic since you will measure something that doesn't count in real life. For all of my projects, both Java and Python have always been fast enough. Of course, I would prefer one language over the other for a specific problem in a certain context.

I read it like "When the iterable is exhausted completely, and the execution is about to proceed to the next statement after finishing the for, the else clause will be executed." Thus, when the iteration is broken by break, this will not be executed.

I ended in this stackoverflow question after looking for help to solve my problem but found no solution to it :(

So I had to improvise... after some time I managed to reach the regex I needed:

As you can see, I needed up to one folder ahead of "grp-bps" folder, without including last dash. And it was required to have at least one folder after "grp-bps" folder.

Edit

Text version for copy-paste (change 'grp-bps' for your text):

.*\/grp-bps\/[^\/]+

As per the comments in the question... On Windows 10 Signtool.exe and other SDK tools have been moved into "%programfiles(x86)%\Windows Kits\".

Typical path to signtool on Windows 10.

• 32 bit = "c:\Program Files (x86)\Windows Kits\10\bin\x86\signtool.exe"
• 64 bit = "c:\Program Files (x86)\Windows Kits\10\bin\x64\signtool.exe"

Tools for SDK 8.0 and 8.1 also reside in the "Windows Kits" folder.

This should do it:

[entry for tag in tags for entry in entries if tag in entry]

If you want to be able to configure it through xml without any modification in java code you may find this idea helpful. Simply you call init from constructor and set the text as html

public class HTMLTextView extends TextView {
    ... constructors calling init...
    private void init(){
       setText(Html.fromHtml(getText().toString()));
    }    
}

xml:

<com.package.HTMLTextView
android:text="@string/about_item_1"/>

new Operator

• This is used to create object from a constructor function
• The new keywords also executes the constructor function

function Car() {
  console.log(this) // this points to myCar
  this.name = "Honda";
}

var myCar = new Car()
console.log(myCar) // Car {name: "Honda", constructor: Object}
console.log(myCar.name) // Honda
console.log(myCar instanceof Car) // true
console.log(myCar.constructor) // function Car() {}
console.log(myCar.constructor === Car) // true
console.log(typeof myCar) // object

Object.create

• You can also use Object.create to create a new object
• But, it does not execute the constructor function
• Object.create is used to create an object from another object

const Car = {
  name: "Honda"
}

var myCar = Object.create(Car)
console.log(myCar) // Object {}
console.log(myCar.name) // Honda
console.log(myCar instanceof Car) // ERROR
console.log(myCar.constructor) // Anonymous function object
console.log(myCar.constructor === Car) // false
console.log(typeof myCar) // object

If you want a real timer you need to use the date object.

Calculate the difference.

Format your string.

window.onload=function(){
      var start=Date.now(),r=document.getElementById('r');
      (function f(){
      var diff=Date.now()-start,ns=(((3e5-diff)/1e3)>>0),m=(ns/60)>>0,s=ns-m*60;
      r.textContent="Registration closes in "+m+':'+((''+s).length>1?'':'0')+s;
      if(diff>3e5){
         start=Date.now()
      }
      setTimeout(f,1e3);
      })();
}

Example

Jsfiddle

not so precise timer

var time=5*60,r=document.getElementById('r'),tmp=time;

setInterval(function(){
    var c=tmp--,m=(c/60)>>0,s=(c-m*60)+'';
    r.textContent='Registration closes in '+m+':'+(s.length>1?'':'0')+s
    tmp!=0||(tmp=time);
},1000);

in standart Vi editor in this situation you should

1. press Esc
2. type ":wq" (without quotes)
3. Press Enter

If you use Db Browser for sqlite ,then it will be easy for you to modify the table. you can add foreign key in existing table without writing a query.

• Open your database in Db browser,
• Just right click on table and click modify,
• At there scroll to foreign key column,
• double click on field which you want to alter,
• Then select table and it's field and click ok.

that's it. You successfully added foreign key in existing table.

Login into the database. then run the below query

select * from dba_role_privs where grantee = 'SCHEMA_NAME';

All the role granted to the schema will be listed.

Thanks Szilagyi Donat for the answer. This one is taken from same and just where clause added.

Assuming your ints are 0, 375, 668,5 and 6:

{
    "Id": "610",
    "Name": "15",
    "Description": "1.99",
    "ItemModList": [
                       0,
                       375,
                       668,
                       5,
                       6
                   ]
}

I suggest that you change "Id": "610" to "Id": 610 since it is a integer/long and not a string. You can read more about the JSON format and examples here http://json.org/

V8 is an implementation of JavaScript. It lets you run standalone JavaScript applications (among other things).

Node.js is simply a library written for V8 which does evented I/O. This concept is a bit trickier to explain, and I'm sure someone will answer with a better explanation than I... The gist is that rather than doing some input or output and waiting for it to happen, you just don't wait for it to finish. So for example, ask for the last edited time of a file:

// Pseudo code
stat( 'somefile' )

That might take a couple of milliseconds, or it might take seconds. With evented I/O you simply fire off the request and instead of waiting around you attach a callback that gets run when the request finishes:

// Pseudo code
stat( 'somefile', function( result ) {
  // Use the result here
} );
// ...more code here

This makes it a lot like JavaScript code in the browser (for example, with Ajax style functionality).

For more information, you should check out the article Node.js is genuinely exciting which was my introduction to the library/platform... I found it quite good.

This is a press down button example I've made:

<div>
    <form id="forminput" action="action" method="POST">
       ...
    </form>
    <div style="right: 0px;bottom: 0px;position: fixed;" class="thumbnail">
        <div class="image">
            <a onclick="document.getElementById('forminput').submit();">
                <img src="images/button.png" alt="Some awesome text">
            </a>
        </div>
    </div>
</div>

the CSS file:

.thumbnail {
    width: 128px;
    height: 128px;
}

.image {
    width: 100%;
    height: 100%;    
}

.image img {
    -webkit-transition: all .25s ease; /* Safari and Chrome */
    -moz-transition: all .25s ease; /* Firefox */
    -ms-transition: all .25s ease; /* IE 9 */
    -o-transition: all .25s ease; /* Opera */
    transition: all .25s ease;
    max-width: 100%;
    max-height: 100%;
}

.image:hover img {
    -webkit-transform:scale(1.05); /* Safari and Chrome */
    -moz-transform:scale(1.05); /* Firefox */
    -ms-transform:scale(1.05); /* IE 9 */
    -o-transform:scale(1.05); /* Opera */
     transform:scale(1.05);
}

.image:active img {
    -webkit-transform:scale(.95); /* Safari and Chrome */
    -moz-transform:scale(.95); /* Firefox */
    -ms-transform:scale(.95); /* IE 9 */
    -o-transform:scale(.95); /* Opera */
     transform:scale(.95);
}

Enjoy it!

Maybe you can iterate over the map looking for the keys to remove and storing them in a separate collection. Then remove the collection of keys from the map. Modifying the map while iterating is usually frowned upon. This idea may be suspect if the map is very large.

You can't, Print Preview is a feature of a browser, and therefore should be protected from being called by JavaScript as it would be a security risk.

That's why your example uses Active X, which bypasses the JavaScript security issues.

So instead use the print stylesheet that you already should have and show it for media=screen,print instead of media=print.

Read Alist Apart: Going to Print for a good article on the subject of print stylesheets.

What you are looking for is called reverse geocoding. Google provides a server-side reverse geocoding service through the Google Geocoding API, which you should be able to use for your project.

This is how a response to the following request would look like:

http://maps.googleapis.com/maps/api/geocode/json?latlng=40.714224,-73.961452&sensor=false

Response:

{
  "status": "OK",
  "results": [ {
    "types": [ "street_address" ],
    "formatted_address": "275-291 Bedford Ave, Brooklyn, NY 11211, USA",

    }, {
      "long_name": "Bedford Ave",
      "short_name": "Bedford Ave",
      "types": [ "route" ]
    }, {
      "long_name": "New York",
      "short_name": "New York",

        }
      }
    }
  },

  ... Additional results[] ...

You can also opt to receive the response in xml instead of json, by simply substituting json for xml in the request URI:

http://maps.googleapis.com/maps/api/geocode/xml?latlng=40.714224,-73.961452&sensor=false

As far as I know, Google will also return the same name for address components, especially for high-level names like country names and city names. Nevertheless, keep in mind that while the results are very accurate for most applications, you could still find the occasional spelling mistake or ambiguous result.

Remote Procedure Call (RPC) is a inter process communication which allows calling a function in another process residing in local or remote machine.

Remote method invocation (RMI) is an API, which implements RPC in java with support of object oriented paradigms.

1. You can think of invoking RPC is like calling a C procedure. RPC supports primitive data types where as RMI support method parameters/return types as java objects.

2. RMI is easy to program unlike RPC. You can think your business logic in terms of objects instead of a sequence of primitive data types.

3. RPC is language neutral unlike RMI, which is limited to java

4. RMI is little bit slower to RPC

Have a look at this article for RPC implementation in C

On Windows 7,64 bit,the above solution (Onur Turhan's) worked for me with slight changes as below

C:\Users\MyName > heroku login

Enter email/password

C:\Users\MyName >ssh-keygen -t rsa -f id_rsa

This generated two files(id_rsa and id_rsa.pub) in my c:\Users\MyName directory (Not in .ssh directory)

heroku keys:add id_rsa.pub
git clone [email protected]:some-heiku-xxxx.git -o heroku

I guess adding the correct "id_rsa.pub" file is the most important.After generating the public key using keygen just verify that you are adding correct key by looking at the time-stamp when it was created.

You can use tail command as follows:

tail -100 <log file>   > newLogfile

Now last 100 lines will be present in newLogfile

EDIT:

More recent versions of tail as mentioned by twalberg use command:

tail -n 100 <log file>   > newLogfile

UPDATED ANSWER

Google Analytics Admin panel has 3 panels, wherein deleting can be done on any of the following :

1. Account (Contains multiple properties, and views)
2. Properties (Contains Views, a subset of Account)
3. Views (subset of properties)

Deleting an Account

Deleting the account, will remove all data pertaining to that account, along with all properties/profiles it contains. This is (usually) as good as removing the entire website data.

To delete the account, follow the following steps : (refer to image below)

• Choose the account you want to delete.

• Click on Account Settings

• Bottom right, a small link that says delete this account.

• You will get a confirmation, if you are sure to, click Delete Account
• It will give you details, and will confirm deletion (and provide additional info like to remove GA snippet on your website, etc)

Note : If you have multiple accounts linked with your login, the other accounts are NOT touched, only this account will be deleted.

Deleting a property

Deleting a property will remove the selected property, and all the views it holds. To delete a property, delete all views it contains individually (see below for deleting views)

• Choose the property

• All profiles related to that property appear on the right
• Delete all the views related to the property individually (details in next section).

Deleting a View (profile)

Deleting a profile will remove only data pertaining to that view, if there is a single profile, the property is automatically deleted.

• Choose the profile you want to delete

• Click View Settings

• Click on delete View (Bottom right)

• Click Confirm, and that view will be deleted. If there is only a single view in the property, that property gets automatically deleted.

I want to keep the data, but not see them in the list

Sometimes you have a lot of websites, which you want to keep the data, but remove them from the list, since you don't view them often. I thought of a workaround, in case you do not want to delete the data.

Use another account.

1. Say, your primary account is A, and you make another account B.
2. Make B an administrator from A
3. Remove A

Since A was your primary account, you no longer will be able to access it from the list!
And you still have your data saved, just that you'll have to log in via the other (spare) account.

Previous Answer :

These are the steps to delete a profile from Google Support page :

Delete profiles

Remember, too, that when you delete a profile, you also delete all data associated with that profile, and it is not possible to retrieve that deleted data.

To delete a profile:

1. Click the Admin tab at the top right of any Analytics page.
2. Click the account that contains the profile you want to delete.
3. Click the web property from which you want to delete the profile.
4. Use the Profile menu to select the profile.
5. Click the Profile Settings tab.
6. Click Delete this profile at the bottom of the page.
7. Click Delete in the confirmation message.

Here a Kotlin version of the function:

fun getBoundsZoomLevel(bounds: LatLngBounds, mapDim: Size): Double {
        val WORLD_DIM = Size(256, 256)
        val ZOOM_MAX = 21.toDouble();

        fun latRad(lat: Double): Double {
            val sin = Math.sin(lat * Math.PI / 180);
            val radX2 = Math.log((1 + sin) / (1 - sin)) / 2;
            return max(min(radX2, Math.PI), -Math.PI) /2
        }

        fun zoom(mapPx: Int, worldPx: Int, fraction: Double): Double {
            return floor(Math.log(mapPx / worldPx / fraction) / Math.log(2.0))
        }

        val ne = bounds.northeast;
        val sw = bounds.southwest;

        val latFraction = (latRad(ne.latitude) - latRad(sw.latitude)) / Math.PI;

        val lngDiff = ne.longitude - sw.longitude;
        val lngFraction = if (lngDiff < 0) { (lngDiff + 360) } else { (lngDiff / 360) }

        val latZoom = zoom(mapDim.height, WORLD_DIM.height, latFraction);
        val lngZoom = zoom(mapDim.width, WORLD_DIM.width, lngFraction);

        return minOf(latZoom, lngZoom, ZOOM_MAX)
    }

A simpler approach would be:

1. Open POSTMAN
2. Click on "import" tab on the upper left side.
3. Select the Raw Text option and paste your cURL command.
4. Hit import and you will have the command in your Postman builder!
5. Click Send to post the command

Hope this helps!

I came across this myself. I used .on so it looks a bit different but I did this:

 $('#element').on('keypress', function() {
   //code to be executed
 }).on('keydown', function(e) {
   if (e.keyCode==8)
     $('element').trigger('keypress');
 });

Adding my Work Around here. I needed to delete ssn typed by user so i did this in jQuery

  $(this).bind("keydown", function (event) {
        // Allow: backspace, delete
        if (event.keyCode == 46 || event.keyCode == 8) 
        {
            var tempField = $(this).attr('name');
            var hiddenID = tempField.substr(tempField.indexOf('_') + 1);
            $('#' + hiddenID).val('');
            $(this).val('')
            return;
        }  // Allow: tab, escape, and enter
        else if (event.keyCode == 9 || event.keyCode == 27 || event.keyCode == 13 ||
        // Allow: Ctrl+A
        (event.keyCode == 65 && event.ctrlKey === true) ||
        // Allow: home, end, left, right
        (event.keyCode >= 35 && event.keyCode <= 39)) {
            // let it happen, don't do anything
            return;
        }
        else 
        {
            // Ensure that it is a number and stop the keypress
            if (event.shiftKey || (event.keyCode < 48 || event.keyCode > 57) &&       (event.keyCode < 96 || event.keyCode > 105)) 
            {
                event.preventDefault();
            }
        }
    });

1. Configure AngularJS

$location / switching between html5 and hashbang mode / link rewriting

2. Configure your server:

https://github.com/angular-ui/ui-router/wiki/Frequently-Asked-Questions#wiki-how-to-configure-your-server-to-work-with-html5mode

I like doing something like this:

Message::select('*')
->from(DB::raw("( SELECT * FROM `messages`
                  WHERE `to_id` = ".Auth::id()." AND `isseen` = 0
                  GROUP BY `from_id` asc) as `sub`"))
->count();

It's not very elegant, but it's simple.

First point is- showing multiple popups is not desirable in terms of usability.

But you can achieve it by using multiple popup names

var newwindow;
function createPop(url, name)
{    
   newwindow=window.open(url,name,'width=560,height=340,toolbar=0,menubar=0,location=0');  
   if (window.focus) {newwindow.focus()}
}

Better approach will be showing both in a single page in two different iFrames or Divs.

Update:

So I will suggest to create a new tab in the test.aspx page to show the report, instead of replacing the image content and placing the pdf.

I work with VS2015, ASP.NET MVC 6 (RC) and also had problems (error messages to the reference, icons not showed) with the gliphicons in production (where it has worked in VS (development)).
The reason seems to be, that the MS cdn page is down (at least right now and from Switzerland): http://www.websitedown.info/ajax.aspnetcdn.com

Therefore (as temporary workaround), I have changed the external reference in _Layout.cshtml (under environment names="Staging,Production") to "internal" reference:
from:

<link rel="stylesheet" href="https://ajax.aspnetcdn.com/ajax/bootstrap/3.3.5/css/bootstrap.min.css"

to

<link rel="stylesheet" href="~/lib/bootstrap/dist/css/bootstrap.min.css"

After doing that, it works again.

We can use flatmap for this, please refer below code :

 List<Integer> i1= Arrays.asList(1, 2, 3, 4);
 List<Integer> i2= Arrays.asList(5, 6, 7, 8);

 List<List<Integer>> ii= Arrays.asList(i1, i2);
 System.out.println("List<List<Integer>>"+ii);
 List<Integer> flat=ii.stream().flatMap(l-> l.stream()).collect(Collectors.toList());
 System.out.println("Flattened to List<Integer>"+flat);

Yes, right click the project. Click Run as then Run Configurations. You can change the parameters passed to the JVM in the Arguments tab in the VM Arguments box.

That configuration can then be used as the default when running the project.

INNER JOIN gets all records that are common between both tables based on the supplied ON clause.

LEFT JOIN gets all records from the LEFT linked and the related record from the right table ,but if you have selected some columns from the RIGHT table, if there is no related records, these columns will contain NULL.

RIGHT JOIN is like the above but gets all records in the RIGHT table.

FULL JOIN gets all records from both tables and puts NULL in the columns where related records do not exist in the opposite table.

This one is pretty fast :

select * from listofvalue l 
inner join tbl on tbl.mycol like '%' || l.value || '%'

I was having an issue with this, my server was running behind a load balancer. The load balancer was terminating the SSL/TLS connection. It then passed the request to the web servers using http.

Using the Url.Action() method with Request.Url.Schema, it kept creating a http url, in my case to create a link in an automated email (which my PenTester didn't like).

I may have cheated a little, but it is exactly what I needed to force a https url:

<a href="@Url.Action("Action", "Controller", new { id = Model.Id }, "https")">Click Here</a>

I actually use a web.config AppSetting so I can use http when debugging locally, but all test and prod environments use transformation to set the https value.

This worked for me:-

Oracle, along with other databases, analyzes a given query to create an execution plan. This plan is the most efficient way of retrieving the data.

Oracle provides the 'explain plan' statement which analyzes the query but doesn't run it, instead populating a special table that you can query (the plan table).

The syntax (simple version, there are other options such as to mark the rows in the plan table with a special ID, or use a different plan table) is:

explain plan for <sql query>

The analysis of that data is left for another question, or your further research.

I didn't find any of the existing solutions fitting - simple HTML emails to simple plain text files.

I've opened up this repository, hope it helps someone. MIT license, by the way :)

https://github.com/RobQuistNL/SimpleHtmlToText

Example:

$myHtml = '<b>This is HTML</b><h1>Header</h1><br/><br/>Newlines';
echo (new Parser())->parseString($myHtml);

returns:

**This is HTML**
### Header ###


Newlines

Look in your settings.xml (or, possibly your project's parent or corporate parent POM) for the <repositories> element. It will look something like the below.

<repositories>
    <repository>
        <id>central</id>
        <url>http://gotoNexus</url>
        <snapshots>
            <enabled>true</enabled>
            <updatePolicy>always</updatePolicy>
        </snapshots>
        <releases>
            <enabled>true</enabled>
            <updatePolicy>daily</updatePolicy>
        </releases>
    </repository>
</repositories>

Note the <updatePolicy> element. The example tells Maven to contact the remote repo (Nexus in my case, Maven Central if you're not using your own remote repo) any time Maven needs to retrieve a snapshot artifact during a build, checking to see if there's a newer copy. The metadata is required for this. If there is a newer copy Maven downloads it to your local repo.

In the example, for releases, the policy is daily so it will check during your first build of the day. never is also a valid option, as described in Maven settings docs.

Plugins are resolved separately. You may have repositories configured for those as well, with different update policies if desired.

<pluginRepositories>
    <pluginRepository>
        <id>central</id>
        <url>http://gotoNexus</url>
        <snapshots>
            <enabled>true</enabled>
            <updatePolicy>daily</updatePolicy>
        </snapshots>
        <releases>
            <enabled>true</enabled>
            <updatePolicy>never</updatePolicy>
        </releases>
    </pluginRepository>
</pluginRepositories>

Someone else mentioned the -o option. If you use that, Maven runs in "offline" mode. It knows it has a local repo only, and it won't contact the remote repo to refresh the artifacts no matter what update policies you use.

Sometimes using libraries are cool when you do not want to reinvent the wheel, but in this case one can do the same job with fewer lines of code and easier to read compared to using libraries. Here is a different approach which I find very easy to use.

1. In this example, I use StreamReader to read the file
2. Regex to detect the delimiter from each line(s).
3. An array to collect the columns from index 0 to n

using (StreamReader reader = new StreamReader(fileName))
    {
        string line; 

        while ((line = reader.ReadLine()) != null)
        {
            //Define pattern
            Regex CSVParser = new Regex(",(?=(?:[^\"]*\"[^\"]*\")*(?![^\"]*\"))");

            //Separating columns to array
            string[] X = CSVParser.Split(line);

            /* Do something with X */
        }
    }

Question has a good pagerank on google, so for anyone who's looking for answer to this question this might be helpful.

There is an extension in google chrome marketspace to do exactly that: https://chrome.google.com/webstore/detail/hccmhjmmfdfncbfpogafcbpaebclgjcp

You have a bad table design. You can't autoincrement a string, that doesn't make any sense. You have basically two options:

1.) change type of ID to int instead of string
2.) not recommended!!! - handle autoincrement by yourself. You first need to get the latest value from the database, parse it to the integer, increment it and attach it to the entity as a string again. VERY BAD idea

First option requires to change every table that has a reference to this table, BUT it's worth it.

with hablar::convert

To easily convert multiple columns to different data types you can use hablar::convert. Simple syntax: df %>% convert(num(a)) converts the column a from df to numeric.

Detailed example

Lets convert all columns of mtcars to character.

df <- mtcars %>% mutate_all(as.character) %>% as_tibble()

> df
# A tibble: 32 x 11
   mpg   cyl   disp  hp    drat  wt    qsec  vs    am    gear  carb 
   <chr> <chr> <chr> <chr> <chr> <chr> <chr> <chr> <chr> <chr> <chr>
 1 21    6     160   110   3.9   2.62  16.46 0     1     4     4    
 2 21    6     160   110   3.9   2.875 17.02 0     1     4     4    
 3 22.8  4     108   93    3.85  2.32  18.61 1     1     4     1    

With hablar::convert:

library(hablar)

# Convert columns to integer, numeric and factor
df %>% 
  convert(int(cyl, vs),
          num(disp:wt),
          fct(gear))

results in:

# A tibble: 32 x 11
   mpg     cyl  disp    hp  drat    wt qsec     vs am    gear  carb 
   <chr> <int> <dbl> <dbl> <dbl> <dbl> <chr> <int> <chr> <fct> <chr>
 1 21        6  160    110  3.9   2.62 16.46     0 1     4     4    
 2 21        6  160    110  3.9   2.88 17.02     0 1     4     4    
 3 22.8      4  108     93  3.85  2.32 18.61     1 1     4     1    
 4 21.4      6  258    110  3.08  3.22 19.44     1 0     3     1   

Here is a great reference for HTML Ascii codes:

http://www.ascii.cl/htmlcodes.htm

The code you are looking for is: &#39;

For php.ini 5.6 version (check version using php -v)

;extension=php_intl.dll ; remove semicolon and keep like this extension=php_intl.dll

For php.ini 7.* version

;extension=intl ; remove semicolon and keep like this extension=intl

Note - After That Make Sure to Restart Your Xampp,Wamp Server in you Local Machine.

I used start /b for this instead of just start and it ran without a window for each command, so there was no waiting.

You can check your g++ by command:

which g++
g++ --version

this will tell you which complier is currently it is pointing.

To switch to g++ 4.7 (assuming that you have installed it in your machine),run:

sudo update-alternatives --config gcc

There are 2 choices for the alternative gcc (providing /usr/bin/gcc).

  Selection    Path              Priority   Status
------------------------------------------------------------
  0            /usr/bin/gcc-4.6   60        auto mode
  1            /usr/bin/gcc-4.6   60        manual mode
* 2            /usr/bin/gcc-4.7   40        manual mode

Then select 2 as selection(My machine already pointing to g++ 4.7,so the *)

Once you switch the complier then again run g++ --version to check the switching has happened correctly.

Now compile your program with

g++ -std=c++11 your_file.cpp -o main

Semantic Difference

According to HTML 5.2:

When specified on an element, [the hidden attribute] indicates that the element is not yet, or is no longer, directly relevant to the page’s current state, or that it is being used to declare content to be reused by other parts of the page as opposed to being directly accessed by the user.

Examples include a tab list where some panels are not exposed, or a log-in screen that goes away after a user logs in. I like to call these things “temporally relevant” i.e. they are relevant based on timing.

On the other hand, ARIA 1.1 says:

[The aria-hidden state] indicates whether an element is exposed to the accessibility API.

In other words, elements with aria-hidden="true" are removed from the accessibility tree, which most assistive technology honors, and elements with aria-hidden="false" will definitely be exposed to the tree. Elements without the aria-hidden attribute are in the "undefined (default)" state, which means user agents should expose it to the tree based on its rendering. E.g. a user agent may decide to remove it if its text color matches its background color.

Now let’s compare semantics. It’s appropriate to use hidden, but not aria-hidden, for an element that is not yet “temporally relevant”, but that might become relevant in the future (in which case you would use dynamic scripts to remove the hidden attribute). Conversely, it’s appropriate to use aria-hidden, but not hidden, on an element that is always relevant, but with which you don’t want to clutter the accessibility API; such elements might include “visual flair”, like icons and/or imagery that are not essential for the user to consume.

Effective Difference

The semantics have predictable effects in browsers/user agents. The reason I make a distinction is that user agent behavior is recommended, but not required by the specifications.

The hidden attribute should hide an element from all presentations, including printers and screen readers (assuming these devices honor the HTML specs). If you want to remove an element from the accessibility tree as well as visual media, hidden would do the trick. However, do not use hidden just because you want this effect. Ask yourself if hidden is semantically correct first (see above). If hidden is not semantically correct, but you still want to visually hide the element, you can use other techniques such as CSS.

Elements with aria-hidden="true" are not exposed to the accessibility tree, so for example, screen readers won’t announce them. This technique should be used carefully, as it will provide different experiences to different users: accessible user agents won’t announce/render them, but they are still rendered on visual agents. This can be a good thing when done correctly, but it has the potential to be abused.

Syntactic Difference

Lastly, there is a difference in syntax between the two attributes.

hidden is a boolean attribute, meaning if the attribute is present it is true—regardless of whatever value it might have—and if the attribute is absent it is false. For the true case, the best practice is to either use no value at all (<div hidden>...</div>), or the empty string value (<div hidden="">...</div>). I would not recommend hidden="true" because someone reading/updating your code might infer that hidden="false" would have the opposite effect, which is simply incorrect.

aria-hidden, by contrast, is an enumerated attribute, allowing one of a finite list of values. If the aria-hidden attribute is present, its value must be either "true" or "false". If you want the "undefined (default)" state, remove the attribute altogether.

If you are using the grid or alike component: In XAML, make sure that the elements in the grid have Grid.Row and Grid.Column defined, and ensure tha they don't have margins. If you used designer mode, or Expression Blend, it could have assigned margins relative to the whole grid instead of to particular cells. As for cell sizing, I add an extra cell that fills up the rest of the space:

    <Grid.RowDefinitions>
        <RowDefinition Height="Auto" />
        <RowDefinition Height="Auto" />
        <RowDefinition Height="Auto" />
        <RowDefinition Height="Auto" />
        <RowDefinition Height="Auto" />
        <RowDefinition Height="*"/>
    </Grid.RowDefinitions>

Here's a simple trap that prints the last argument of whatever failed to STDERR, reports the line it failed on, and exits the script with the line number as the exit code. Note these are not always great ideas, but this demonstrates some creative application you could build on.

trap 'echo >&2 "$_ at $LINENO"; exit $LINENO;' ERR

I put that in a script with a loop to test it. I just check for a hit on some random numbers; you might use actual tests. If I need to bail, I call false (which triggers the trap) with the message I want to throw.

For elaborated functionality, have the trap call a processing function. You can always use a case statement on your arg ($_) if you need to do more cleanup, etc. Assign to a var for a little syntactic sugar -

trap 'echo >&2 "$_ at $LINENO"; exit $LINENO;' ERR
throw=false
raise=false

while :
do x=$(( $RANDOM % 10 ))
   case "$x" in
   0) $throw "DIVISION BY ZERO" ;;
   3) $raise "MAGIC NUMBER"     ;;
   *) echo got $x               ;;
   esac
done

Sample output:

# bash tst
got 2
got 8
DIVISION BY ZERO at 6
# echo $?
6

Obviously, you could

runTest1 "Test1 fails" # message not used if it succeeds

Lots of room for design improvement.

The draw backs include the fact that false isn't pretty (thus the sugar), and other things tripping the trap might look a little stupid. Still, I like this method.

You can use the ATL text conversion macros to convert a narrow (char) string to a wide (wchar_t) one. For example, to convert a std::string:

#include <atlconv.h>
...
std::string str = "Hello, world!";
CA2W pszWide(str.c_str());
loadU(pszWide);

You can also specify a code page, so if your std::string contains UTF-8 chars you can use:

CA2W pszWide(str.c_str(), CP_UTF8);

Very useful but Windows only.

just add your .jar file in applet tag as an attribute as shown below:

<applet
    code="file.class"
    archive="file.jar"
    height=550 
    width=1100>         
</applet>

"Allocation Failure" is a cause of GC cycle to kick in.

"Allocation Failure" means that no more space left in Eden to allocate object. So, it is normal cause of young GC.

Older JVM were not printing GC cause for minor GC cycles.

"Allocation Failure" is almost only possible cause for minor GC. Another reason for minor GC to kick could be CMS remark phase (if +XX:+ScavengeBeforeRemark is enabled).

I had problem to catch "shown.bs.modal" event.. And this is my solution which works perfect..

Instead simple on():

Use on() with delegated element:

$('body').on 'shown.bs.modal', '#modal', ->

Now there are a lot of cloud providers , providing solutions like MBaaS (Mobile Backend as a Service). Some only give access to cloud database, some will do the user management for you, some let you place code around cloud database and there are facilities of access control, push notifications, analytics, integrated image and file hosting etc.

Here are some providers which have a "free-tier" (may change in future):

I'm not sure what you mean by a string that contains binary numbers. But for reversing a string (or any STL-compatible container), you can use std::reverse(). std::reverse() operates in place, so you may want to make a copy of the string first:

#include <algorithm>
#include <iostream>
#include <string>

int main()
{
    std::string foo("foo");
    std::string copy(foo);
    std::cout << foo << '\n' << copy << '\n';

    std::reverse(copy.begin(), copy.end());
    std::cout << foo << '\n' << copy << '\n';
}

I think this code will solve your problem

DateTime.Now.ToString("HH:mm")

MySQL recommends using indexes for a variety of reasons including elimination of rows between conditions: http://dev.mysql.com/doc/refman/5.0/en/mysql-indexes.html

This makes your datetime column an excellent candidate for an index if you are going to be using it in conditions frequently in queries. If your only condition is BETWEEN NOW() AND DATE_ADD(NOW(), INTERVAL 30 DAY) and you have no other index in the condition, MySQL will have to do a full table scan on every query. I'm not sure how many rows are generated in 30 days, but as long as it's less than about 1/3 of the total rows it will be more efficient to use an index on the column.

Your question about creating an efficient database is very broad. I'd say to just make sure that it's normalized and all appropriate columns are indexed (i.e. ones used in joins and where clauses).

The simplest is to do a PivotChart. Select your array of dates (with a header) and create a new Pivot Chart (Insert / PivotChart / Ok) Then on the field list window, drag and drop the date column in the Axis list first and then in the value list first.

1. All new browser support video to be auto-played with being muted only so please put

<video autoplay muted="muted" loop id="myVideo"> <source src="https://w.r.glob.net/Coastline-3581.mp4" type="video/mp4"> </video>

Something like this

2. URL of video should match the SSL status if your site is running with https then video URL should also in https and same for HTTP

Instead of using button . you can use Text in react native and then make in touchable

<TouchableOpacity onPress={this._onPressButton}> 
   <Text style = {'your custome style'}>
       button name
   </Text>
</TouchableOpacity >

You should use Java's built in serialization mechanism. To use it, you need to do the following:

1. Declare the Club class as implementing Serializable:

   public class Club implements Serializable {
       ...
   }
   

   This tells the JVM that the class can be serialized to a stream. You don't have to implement any method, since this is a marker interface.

2. To write your list to a file do the following:

   FileOutputStream fos = new FileOutputStream("t.tmp");
   ObjectOutputStream oos = new ObjectOutputStream(fos);
   oos.writeObject(clubs);
   oos.close();
   

3. To read the list from a file, do the following:

   FileInputStream fis = new FileInputStream("t.tmp");
   ObjectInputStream ois = new ObjectInputStream(fis);
   List<Club> clubs = (List<Club>) ois.readObject();
   ois.close();
   

I think that while not elegant, the oplog could be partially used for this purpose: it logs all the writes - but not the reads...

You have to enable replicatoon, if I'm right. The information is from this answer from this question: How to listen for changes to a MongoDB collection?

The easiest way in your case (horizontal line) is to add a subview with black background color and frame [0, 200, 320, 1].

Code sample (I hope there are no errors - I wrote it without Xcode):

UIView *lineView = [[UIView alloc] initWithFrame:CGRectMake(0, 200, self.view.bounds.size.width, 1)];
lineView.backgroundColor = [UIColor blackColor];
[self.view addSubview:lineView];
[lineView release];
// You might also keep a reference to this view 
// if you are about to change its coordinates.
// Just create a member and a property for this...

Another way is to create a class that will draw a line in its drawRect method (you can see my code sample for this here).

And as an addendum to all answers, FYI: override is not a keyword, but a special kind of identifier! It has meaning only in the context of declaring/defining virtual functions, in other contexts it's just an ordinary identifier. For details read 2.11.2 of The Standard.

#include <iostream>

struct base
{
    virtual void foo() = 0;
};

struct derived : base
{
    virtual void foo() override
    {
        std::cout << __PRETTY_FUNCTION__ << std::endl;
    }
};

int main()
{
    base* override = new derived();
    override->foo();
    return 0;
}

Output:

zaufi@gentop /work/tests $ g++ -std=c++11 -o override-test override-test.cc
zaufi@gentop /work/tests $ ./override-test
virtual void derived::foo()

The self name is used as the instance reference in class instances. It is only used in class method definitions. Don't use it in functions.

You also cannot reference local variables from other functions or methods with it. You can only reference instance or class attributes using it.

You just use the method

public Object put(Object key, Object value)

if the key was already present in the Map then the previous value is returned.

They are stored in the CGI fieldstorage object.

import cgi
form = cgi.FieldStorage()

print "The user entered %s" % form.getvalue("uservalue")

I want to mention additional things and make a conclusion.

Commonly, As Otherones explained, This exception will raise when there is a problem with loading expected type (in an existing assembly) in runtime. More specific, Whenever there is loaded assembly that is stale (and not contains the requiring type). Or when an assembly with different version or build is already loaded that not contains the expected type.

Also, I must mention that It seems Rarely, But It is possible to be runtime limitation or a compiler bug (suppose compiler not negated about something and just compiled problematic code), But runtime throws System.TypeLoadException exception. Yes; this actually occurred for me!

An Example (witch occurred for me)

Consider an struct that defines a nullable field of its own type inside itself. Defining such the filed non-nullable, will take you a compile-time error and prevents you from build (Obviously This behavior has a logical reason). But what about nullable struct filed? Actually, nullable value-types is Nullable<T> at behind. As c# compiler not prevented me from defining in this way, I tried it and the project built. But I get runtime exception System.TypeLoadException: 'Could not load type 'SomeInfo' from assembly ... ', And It seems to be Problem in loading the part of my code (otherwise, we may say: the compiler not-truly performed compilation process at least) for me in my environment:

public struct SomeInfo
{
   public SomeInfo? Parent { get; } 
   
   public string info { get; }
}

My environment specs:

• Visual Studio 2019 16.4.4
• Language Version: c# 7.3
• Project type: netstandard 2.0.3 library
• Runtime: classic DotNetFramework 4.6.1

(I checked and ensured that the compiled assembly is up to date And actually is newly compiled. Even, I throwed away all bin directory and refreshed the whole project. Even I created a new project in a fresh solution and tested, But such the struct generates the exception.)

It seems to be a runtime limitation (logically or technically) or bug or a same problem else, because Visual Studio not prevents me from compile And Also other newer parts of my codes (excluding this struct) are executing fine. Changing the struct to a class, the compiled assembly contains and executes the type as well.

I have no any idea to explain in-detail why this behavior occurs in my environment, But I faced this situation.

Conclusion

Check the situations:

• When a same (probably older) assembly already exists in GAC that is overriding the referenced assembly.

• When re-compilation was need but not performed automatically (therefore the referenced assembly is not updated) and there is needs to perform build manually or fix solution build configuration.

• When a custom tool or middleware or third-party executable (such as tests runner tool or IIS) loaded an older version of that assembly from cached things and there is need to cleaning somethings up or causing to reset somethings.

• When an Unappropriated Configuration caused demanding a no longer existing type by a custom tool or middleware or a third-party executable that loads the assembly and there is need to update configuration or cleaning somethings up (such as removing an http handler in web.config file on IIS deployment as @Brian-Moeskau said)

• When there is a logical or technical problem for runtime to execute the compiled assembly, (for example when compiler was compiled a problematic code that the in-using runtime cannot understand or execute it), as I faced.

Other option is not to use crontab -e at all. Instead I used:

(crontab -l && echo "1 1  * * *  /path/to/my/script.sh") | crontab -

Notice that whatever you print before | crontab - will replace the entire crontab file, so use crontab -l && echo "<your new schedule>" to get the previous content and the new schedule.

you can update the setting under init.ora in oraclexe\app\oracle\product\11.2.0\server\config\scripts

Your query apparently returned all correct dates, even considering the time.

If you're still not happy with the results, give DATEDIFF a shot and look for negaive/positive results between the two dates.

Make sure your mydate column is a datetime type.

This should do it, let me know if you have trouble with it:

Sub foo()
Dim x As Workbook
Dim y As Workbook

'## Open both workbooks first:
Set x = Workbooks.Open(" path to copying book ")
Set y = Workbooks.Open(" path to destination book ")

'Now, copy what you want from x:
x.Sheets("name of copying sheet").Range("A1").Copy

'Now, paste to y worksheet:
y.Sheets("sheetname").Range("A1").PasteSpecial

'Close x:
x.Close

End Sub

Alternatively, you could just:

Sub foo2()
Dim x As Workbook
Dim y As Workbook

'## Open both workbooks first:
Set x = Workbooks.Open(" path to copying book ")
Set y = Workbooks.Open(" path to destination book ")

'Now, transfer values from x to y:
y.Sheets("sheetname").Range("A1").Value = x.Sheets("name of copying sheet").Range("A1") 

'Close x:
x.Close

End Sub

To extend this to the entire sheet:

With x.Sheets("name of copying sheet").UsedRange
    'Now, paste to y worksheet:
    y.Sheets("sheet name").Range("A1").Resize( _
        .Rows.Count, .Columns.Count) = .Value
End With

And yet another way, store the value as a variable and write the variable to the destination:

Sub foo3()
Dim x As Workbook
Dim y As Workbook
Dim vals as Variant

'## Open both workbooks first:
Set x = Workbooks.Open(" path to copying book ")
Set y = Workbooks.Open(" path to destination book ")

'Store the value in a variable:
vals = x.Sheets("name of sheet").Range("A1").Value

'Use the variable to assign a value to the other file/sheet:
y.Sheets("sheetname").Range("A1").Value = vals 

'Close x:
x.Close

End Sub

The last method above is usually the fastest for most applications, but do note that for very large datasets (100k rows) it's observed that the Clipboard actually outperforms the array dump:

Copy/PasteSpecial vs Range.Value = Range.Value

That said, there are other considerations than just speed, and it may be the case that the performance hit on a large dataset is worth the tradeoff, to avoid interacting with the Clipboard.

If you don't want to install anything but do want to download an SVN or GIT repository, then you can use this: http://downloadsvn.codeplex.com/

I have nothing to do with this project, but I just used it now and it saved me a few minutes. Maybe it will help someone.

The command bellow wont work always. If you do just:

$ git checkout thebranch
Already on 'thebranch'
Your branch and 'origin/thebranch' have diverged,
and have 23 and 7 different commits each, respectively.

$ git reset --hard
HEAD is now at b05f611 Here the commit message bla, bla

$ git pull
Auto-merging thefile1.c
CONFLICT (content): Merge conflict in thefile1.c
Auto-merging README.md
CONFLICT (content): Merge conflict in README.md
Automatic merge failed; fix conflicts and then commit the result.

and so on...

To really start over, downloading thebranch and overwriting all your local changes, just do:

$ git checkout thebranch
$ git reset --hard origin/thebranch

This will work just fine.

$ git checkout thebranch
Already on 'thebranch'
Your branch and 'origin/thebranch' have diverged,
and have 23 and 7 different commits each, respectively.

$ git reset --hard origin/thebranch
HEAD is now at 7639058 Here commit message again...

$ git status
# On branch thebranch
nothing to commit (working directory clean)

$ git checkout thebranch

Internet Explorer doesn't fully support Flexbox due to:

Partial support is due to large amount of bugs present (see known issues).

_{Screenshot and infos taken from caniuse.com}

Notes

Internet Explorer before 10 doesn't support Flexbox, while IE 11 only supports the 2012 syntax.

Known issues

• IE 11 requires a unit to be added to the third argument, the flex-basis property see MSFT documentation.
• In IE10 and IE11, containers with display: flex and flex-direction: column will not properly calculate their flexed childrens' sizes if the container has min-height but no explicit height property. See bug.
• In IE10 the default value for flex is 0 0 auto rather than 0 1 auto as defined in the latest spec.
• IE 11 does not vertically align items correctly when min-height is used. See bug.

Workarounds

Flexbugs is a community-curated list of Flexbox issues and cross-browser workarounds for them. Here's a list of all the bugs with a workaround available and the browsers that affect.

1. Minimum content sizing of flex items not honored
2. Column flex items set to align-items: center overflow their container
3. min-height on a flex container won't apply to its flex items
4. flex shorthand declarations with unitless flex-basis values are ignored
5. Column flex items don't always preserve intrinsic aspect ratios
6. The default flex value has changed
7. flex-basis doesn't account for box-sizing: border-box
8. flex-basis doesn't support calc()
9. Some HTML elements can't be flex containers
10. align-items: baseline doesn't work with nested flex containers
11. Min and max size declarations are ignored when wrapping flex items
12. Inline elements are not treated as flex-items
13. Importance is ignored on flex-basis when using flex shorthand
14. Shrink-to-fit containers with flex-flow: column wrap do not contain their items
15. Column flex items ignore margin: auto on the cross axis
16. flex-basis cannot be animated
17. Flex items are not correctly justified when max-width is used

You can try this

<select name="select1" onmousedown="if(this.options.length>8){this.size=8;}"  onchange='this.size=0;' onblur="this.size=0;">_x000D_
             <option value="1">This is select number 1</option>_x000D_
             <option value="2">This is select number 2</option>_x000D_
             <option value="3">This is select number 3</option>_x000D_
             <option value="4">This is select number 4</option>_x000D_
             <option value="5">This is select number 5</option>_x000D_
             <option value="6">This is select number 6</option>_x000D_
             <option value="7">This is select number 7</option>_x000D_
             <option value="8">This is select number 8</option>_x000D_
             <option value="9">This is select number 9</option>_x000D_
             <option value="10">This is select number 10</option>_x000D_
             <option value="11">This is select number 11</option>_x000D_
             <option value="12">This is select number 12</option>_x000D_
           </select>

It worked for me

a very simple, one-line solution, is to add line-heigth to the div, having in mind that all the div's text will go bottom.

CSS:

#layer{width:198px;
       height:48px;
       line-height:72px;
       border:1px #000 solid}
#layer a{text-decoration:none;}

HTML:

<div id="layer">
    <a href="#">text at div's bottom.</a>
</div>

keep in mind that this is a practical and fast solution when you just want text inside div to go down, if you need to combine images and stuff, you will have to code a bit more complex and responsive CSS

If you're using C# 6 or later, you can use expression-bodied syntax for get-only indexer:

public object this[int i] => this.InnerList[i];

At first it seems as if JNZ means jump if not Zero (0), as in jump if zero flag is 1/set.

But in reality it means Jump (if) not Zero (is set).

If 0 = not set and 1 = set then just remember:
JNZ Jumps if the zero flag is not set (0)

This works using java.util.Scanner and will take multiple "enter" keystrokes:

    Scanner scanner = new Scanner(System.in);
    String readString = scanner.nextLine();
    while(readString!=null) {
        System.out.println(readString);

        if (readString.isEmpty()) {
            System.out.println("Read Enter Key.");
        }

        if (scanner.hasNextLine()) {
            readString = scanner.nextLine();
        } else {
            readString = null;
        }
    }

To break it down:

Scanner scanner = new Scanner(System.in);
String readString = scanner.nextLine();

These lines initialize a new Scanner that is reading from the standard input stream (the keyboard) and reads a single line from it.

    while(readString!=null) {
        System.out.println(readString);

While the scanner is still returning non-null data, print each line to the screen.

        if (readString.isEmpty()) {
            System.out.println("Read Enter Key.");
        }

If the "enter" (or return, or whatever) key is supplied by the input, the nextLine() method will return an empty string; by checking to see if the string is empty, we can determine whether that key was pressed. Here the text Read Enter Key is printed, but you could perform whatever action you want here.

        if (scanner.hasNextLine()) {
            readString = scanner.nextLine();
        } else {
            readString = null;
        }

Finally, after printing the content and/or doing something when the "enter" key is pressed, we check to see if the scanner has another line; for the standard input stream, this method will "block" until either the stream is closed, the execution of the program ends, or further input is supplied.

I'm going to put in a vote for np.vectorize. It allows you to just shoot over x number of columns and not deal with the dataframe in the function, so it's great for functions you don't control or doing something like sending 2 columns and a constant into a function (i.e. col_1, col_2, 'foo').

import numpy as np
import pandas as pd

df = pd.DataFrame({'ID':['1','2','3'], 'col_1': [0,2,3], 'col_2':[1,4,5]})
mylist = ['a','b','c','d','e','f']

def get_sublist(sta,end):
    return mylist[sta:end+1]

#df['col_3'] = df[['col_1','col_2']].apply(get_sublist,axis=1)
# expect above to output df as below 

df.loc[:,'col_3'] = np.vectorize(get_sublist, otypes=["O"]) (df['col_1'], df['col_2'])


df

ID  col_1   col_2   col_3
0   1   0   1   [a, b]
1   2   2   4   [c, d, e]
2   3   3   5   [d, e, f]

You should enable the management plugin.

rabbitmq-plugins enable rabbitmq_management

See here:

http://www.rabbitmq.com/plugins.html

And here for the specifics of management.

http://www.rabbitmq.com/management.html

Finally once set up you will need to follow the instructions below to install and use the rabbitmqadmin tool. Which can be used to fully interact with the system. http://www.rabbitmq.com/management-cli.html

For example:

rabbitmqadmin get queue=<QueueName> requeue=false

will give you the first message off the queue.

As pointed out by @MaNn in one of the comments of the accepted answers, the solution wont work if the page is refreshed.

The Solution for this is to use localStorage or sessionStorage for temporary persistence of the data you want to share across controllers.

1. Either you make a sessionService whose GET and SET method, encrypts and decrypts the data and reads the data from either localStorage or sessionStorage. So now you use this service directly to read and write the data in the storage via any controller or service you want. This is a open approach and easy one
2. Else you make a DataSharing Service and use localStorage inside it - so that if the page is refreshed the service will try and check the storage and reply back via the Getters and Setters you have made public or private in this service file.

I already have used Reportlab in one project.

I am aware there are already several answers, but I added this, as this adds substantial information about the decimal places and hence the asked maximum length.

The length of latitude and langitude depend on precision. The absolute maximum length for each is:

• Latitude: 12 characters (example: -90.00000001)
• Longitude: 13 characters (example: -180.00000001)

For both holds: a maximum of 8 decial places is possible (though not commonly used).

Explanation for the dependency on precision:

See the full table at Decimal degrees article on Wikipedia

More on gdoron's answer, it can also be done this way:

$(window).on("click", "#filter", function() {
    alert('clicked!');
});

without the need to place them all into $(function(){...})

Sub test()
    MsgBox Worksheets("sheet_name").Range("A65536").End(xlUp).Row
End Sub

This is looking for a value in column A because of "A65536".

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

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

You want to leave out username:

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

Try wrapping the createtable(); statement in a <script> tag:

<table>
        <tr>
            <th>Balance</th>
            <th>Fee</th>

        </tr>
        <script>createtable();</script>
</table>

I would avoid using document.write() and use the DOM if I were you though.

DECLARE @records varchar(400)
SELECT @records = 'a,b,c,d'
select  LEN(@records) as 'Before removing Commas' , LEN(@records) - LEN(REPLACE(@records, ',', '')) 'After Removing Commans'

The command palette tells you the colours and their order when col = somefactor. It can also be used to set the colours as well.

palette()
[1] "black"   "red"     "green3"  "blue"    "cyan"    "magenta" "yellow"  "gray"   

In order to see that in your graph you could use a legend.

legend('topright', legend = levels(iris$Species), col = 1:3, cex = 0.8, pch = 1)

You'll notice that I only specified the new colours with 3 numbers. This will work like using a factor. I could have used the factor originally used to colour the points as well. This would make everything logically flow together... but I just wanted to show you can use a variety of things.

You could also be specific about the colours. Try ?rainbow for starters and go from there. You can specify your own or have R do it for you. As long as you use the same method for each you're OK.

Pull "pulls" the div towards the left of the browser and and Push "pushes" the div away from left of browser.

Like:

So basically in a 3 column layout of any web page the "Main Body" appears at the "Center" and in "Mobile" view the "Main Body" appears at the "Top" of the page. This is mostly desired by everyone with 3 column layout.

<div class="container">
    <div class="row">
        <div id="content" class="col-lg-4 col-lg-push-4 col-sm-12">
        <h2>This is Content</h2>
        <p>orem Ipsum ...</p>
        </div>

        <div id="sidebar-left" class="col-lg-4  col-sm-6 col-lg-pull-4">
        <h2>This is Left Sidebar</h2>
        <p>orem Ipsum...</p>
        </div>


        <div id="sidebar-right" class="col-lg-4 col-sm-6">
        <h2>This is Right Sidebar</h2>
        <p>orem Ipsum.... </p>
        </div>
    </div>

A char can hold a single character only, a character literal is a single character in single quote, i.e. '&' - if you have more characters than one you want to use a string, for that you have to use double quotes:

case "&&": 

You could create a unique index with a coalesce on the MenuId:

CREATE UNIQUE INDEX
Favorites_UniqueFavorite ON Favorites
(UserId, COALESCE(MenuId, '00000000-0000-0000-0000-000000000000'), RecipeId);

You'd just need to pick a UUID for the COALESCE that will never occur in "real life". You'd probably never see a zero UUID in real life but you could add a CHECK constraint if you are paranoid (and since they really are out to get you...):

alter table Favorites
add constraint check
(MenuId <> '00000000-0000-0000-0000-000000000000')

UPDATE: By version 41 of Google Chrome, initMouseEvent seemed to have a changed behavior.

this can be done by simulating ctrl + click (or any other key/event combinations that open a background tab) on a dynamically generated a element with its href attribute set to the desired url

In action: fiddle

function openNewBackgroundTab(){
    var a = document.createElement("a");
    a.href = "http://www.google.com/";
    var evt = document.createEvent("MouseEvents");
    //the tenth parameter of initMouseEvent sets ctrl key
    evt.initMouseEvent("click", true, true, window, 0, 0, 0, 0, 0,
                                true, false, false, false, 0, null);
    a.dispatchEvent(evt);
}

Note that testers are no longer added via UUID in the new Apple TestFlight.

Test Flight builds now require an App Store Distribution Provisioning Profile. The portal does not allow UUIDs to be added to this type of provisioning profile.

Instead, add "Internal Testers" via iTunes Connect:

Internal testers are iTunes Connect users with the Admin or Technical role. They can be added in Users and Roles.

After adding a user, be sure to click on their name and flip the "Internal Tester" switch.

Then, go to App > Prerelease > Internal Testers and invite them to the build.

Strings are immutable i.e if you change their value, the old value will be discarded and a new value is created on the heap, whereas in string builder we can modify the existing value without the new value being created.

So performance-wise String Builder is beneficial as we are needlessly not occupying more memory space.

Supplemental answer

Here is a visual supplement to the other answers. My fuller answer with the code and explanations is here.

• Red: text about to be deleted (replaced)
• Green: text that was just added (replacing the old red text)

I think that your mistake is in that your route should be product instead of /product.

So more something like

  children: [
  { 
    path: '', 
    component: AboutHomeComponent
   },
   { 
    path: 'product', 
    component: AboutItemComponent 
   }
 ]

Try with combination: Ctrl + Alt + Space

json_encode() will only encode public member variables. so if you want to include the private once you have to do it by yourself (as the others suggested)

In gcc, this isn't supported. In fact, this isn't supported in any existing compiler/linker i'm aware of.

In Ruby 2.1 it is simple:

h.sort.to_h

PreparedStatement

You should definitely use a PreparedStatement. (Tutorial)

That way you can invoke:

pstmt.setDate( 1, aDate );

The JDBC driver will do date-time handling appropriate for your particular database.

Also, a PreparedStatement stops any SQL injection hacking attempts – very important! (humor)

It should look like this:

SimpleDateFormat format = new SimpleDateFormat( "MM/dd/yyyy" );  // United States style of format.
java.util.Date myDate = format.parse( "10/10/2009" );  // Notice the ".util." of package name.

PreparedStatement pstmt = connection.prepareStatement(
"INSERT INTO USERS ( USER_ID, FIRST_NAME, LAST_NAME, SEX, DATE ) " +
" values (?, ?, ?, ?, ? )");

pstmt.setString( 1, userId );
pstmt.setString( 3, myUser.getLastName() ); 
pstmt.setString( 2, myUser.getFirstName() ); // please use "getFir…" instead of "GetFir…", per Java conventions.
pstmt.setString( 4, myUser.getSex() );
java.sql.Date sqlDate = new java.sql.Date( myDate.getTime() ); // Notice the ".sql." (not "util") in package name.
pstmt.setDate( 5, sqlDate ); 

And that's it, the JDBC driver will create the right SQL syntax for you.

Retrieving

When retrieving a Date object, you can use a SimpleDateFormat to create a formatted string representation of the date-time value.

Here is one quick example line, but search StackOverflow for many more.

String s = new SimpleDateFormat("dd/MM/yyyy").format( aDate );

Just FYI, Geocoder is asynchronous so the accepted answer while logical doesn't really work in this instance. I would prefer to have an outside object that acts as your updater.

var updater = {};

function geoCodeCity(goocoord) { 
    var geocoder = new google.maps.Geocoder();
    geocoder.geocode({
        'latLng': goocoord
    }, function(results, status) {
        if (status == google.maps.GeocoderStatus.OK) {
            updater.currentLocation = results[1].formatted_address;
        } else {
            if (status == "ERROR") { 
                    console.log(status);
                }
        }
    });
};

Ben's code requires the parent div to have the form-group class (I was using btn-group), this is a slightly different version which just searches for the closest div and may even be a bit faster.

$(".dropdown-menu li a").click(function(){
    var selText = $(this).text();
    $(this).closest('div').find('button[data-toggle="dropdown"]').html(selText + ' <span class="caret"></span>');
});

Numeric precision refers to the maximum number of digits that are present in the number.

ie 1234567.89 has a precision of 9

Numeric scale refers to the maximum number of decimal places

ie 123456.789 has a scale of 3

Thus the maximum allowed value for decimal(5,2) is 999.99

Activity 1 uses startActivityForResult:

startActivityForResult(ActivityTwo, ActivityTwoRequestCode);

Activity 2 is launched and you can perform the operation, to close the Activity do this:

Intent output = new Intent();
output.putExtra(ActivityOne.Number1Code, num1);
output.putExtra(ActivityOne.Number2Code, num2);
setResult(RESULT_OK, output);
finish();

Activity 1 - returning from the previous activity will call onActivityResult:

@Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
    if (requestCode == ActivityTwoRequestCode && resultCode == RESULT_OK && data != null) {
        num1 = data.getIntExtra(Number1Code);
        num2 = data.getIntExtra(Number2Code);
    }
}

UPDATE: Answer to Seenu69's comment, In activity two,

int result = Integer.parse(EditText1.getText().toString()) 
           + Integer.parse(EditText2.getText().toString());
output.putExtra(ActivityOne.KEY_RESULT, result);

Then in activity one,

int result = data.getExtra(KEY_RESULT);

It's because you have turned on USB debugging in Developer Options. You can create a bug report by holding the power + both volume up and down.

Edit: This is what the forums say:

By pressing Volume up + Volume down + power button, you will feel a vibration after a second or so, that's when the bug reporting initiated.

To disable:

/system/bin/bugmailer.sh must be deleted/renamed.

There should be a folder on your SD card called "bug reports".

Have a look at this thread: http://forum.xda-developers.com/showthread.php?t=2252948

And this one: http://forum.xda-developers.com/showthread.php?t=1405639

Use the split function.

static void Main(string[] args)
{
    string s = "223232-1.jpg";
    Console.WriteLine(s.Split('-')[0]);
    s = "443-2.jpg";
    Console.WriteLine(s.Split('-')[0]);
    s = "34443553-5.jpg";
    Console.WriteLine(s.Split('-')[0]);

Console.ReadKey();
}

If your string doesn't have a - then you'll get the whole string.

Use : instead of =

see the example below that gives an error

app.post('/mews', (req, res) => {
if (isValidMew(req.body)) {
    // insert into db
    const mew = {
        name = filter.clean(req.body.name.toString()),
        content = filter.clean(req.body.content.toString()),
        created: new Date()
    };

That gives Syntex Error: invalid shorthand proprty initializer.

Then i replace = with : that's solve this error.

app.post('/mews', (req, res) => {
if (isValidMew(req.body)) {
    // insert into db
    const mew = {
        name: filter.clean(req.body.name.toString()),
        content: filter.clean(req.body.content.toString()),
        created: new Date()
    };

If calculating with dates summertime will cause often 1 uur more or one hour less than midnight (CEST). This causes 1 day difference when dates return. So the dates have to round to the nearest midnight. So the code will be (ths to jamisOn):

    var d = new Date();
    if(d.getHours() < 12) {
    d.setHours(0,0,0,0); // previous midnight day
    } else {
    d.setHours(24,0,0,0); // next midnight day
    }

You should use the exit keyword.

PHP evaluates an empty string to false, so you can simply use:

if (trim($userinput['phoneNumber'])) {
  // validate the phone number
} else {
  echo "Phone number not entered<br/>";
}

I was facing the same issue with MSBuild for VS 17

I solved this by applying the following steps:

• In my case the Microsoft.Cpp.Default.props file was located at C:\Program Files (x86)\Microsoft Visual Studio\2017\BuildTools\Common7\IDE\VC\VCTargets so I created VCTragetsPath string in the registry under HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\MSBuild\ToolsVersions\4.0 with value C:\Program Files (x86)\Microsoft Visual Studio\2017\BuildTools\Common7\IDE\VC\VCTargets

• I also made my Jenkins run as an admin user

This solved my issue.

Try:

num3 = 100000000000LL;

And BTW, in C++ this is a compiler extension, the standard does not define long long, thats part of C99.

Regex.Split(string, "xx")

is the way I do it usually.

Of course you'll need:

using System.Text.RegularExpressions;

or :

System.Text.RegularExpressions.Regex.Split(string, "xx")

but then again I need that library all the time.

Here is an example which I use in my source code. I am getting key and value from Dictionary from element 0 to number of elements in my Dictionary. Then I fill my string[] array which I send as a parameter after in my function which accept only params string[]

Dictionary<string, decimal> listKomPop = addElements();
int xpopCount = listKomPop.Count;
if (xpopCount > 0)
{
    string[] xpostoci = new string[xpopCount];
    for (int i = 0; i < xpopCount; i++)
    {
        /* here you have key and value element */
        string key = listKomPop.Keys.ElementAt(i);
        decimal value = listKomPop[key];

        xpostoci[i] = value.ToString();
    }
...

This solution works with SortedDictionary also.

Looking at the code always helps too. That is, you can actually take a look at the generated partial class (that calls LoadComponent) by doing the following:

1. Go to the Solution Explorer pane in the Visual Studio solution that you are interested in.
2. There is a button in the tool bar of the Solution Explorer titled 'Show All Files'. Toggle that button.
3. Now, expand the obj folder and then the Debug or Release folder (or whatever configuration you are building) and you will see a file titled YourClass.g.cs.

The YourClass.g.cs ... is the code for generated partial class. Again, if you open that up you can see the InitializeComponent method and how it calls LoadComponent ... and much more.

You need to use an ObjectMapper:

ObjectMapper mapper = new ObjectMapper();
JsonFactory factory = mapper.getJsonFactory(); // since 2.1 use mapper.getFactory() instead
JsonParser jp = factory.createJsonParser("{\"k1\":\"v1\"}");
JsonNode actualObj = mapper.readTree(jp);

Further documentation about creating parsers can be found here.

To write inline styling use:

<div style="height: 100px;">
asdfashdjkfhaskjdf
</div>

Inline styling serves a purpose however, it is not recommended in most situations.

The more "proper" solution, would be to make a separate CSS sheet, include it in your HTML document, and then use either an ID or a class to reference your div.

if you have the file structure:

index.html
>>/css/
>>/css/styles.css

Then in your HTML document between <head> and </head> write:

<link href="css/styles.css" rel="stylesheet" />

Then, change your div structure to be:

<div id="someidname" class="someclassname">
    asdfashdjkfhaskjdf
</div>

In css, you can reference your div from the ID or the CLASS.

To do so write:

.someclassname { height: 100px; }

OR

#someidname { height: 100px; }

Note that if you do both, the one that comes further down the file structure will be the one that actually works.

For example... If you have:

.someclassname { height: 100px; }

.someclassname { height: 150px; }

Then in this situation the height will be 150px.

EDIT:

To answer your secondary question from your edit, probably need overflow: hidden; or overflow: visible; . You could also do this:

<div class="span12">
    <div style="height:100px;">
        asdfashdjkfhaskjdf
    </div>
</div>

SELECT COLUMN_NAME 
FROM YourDatabase.INFORMATION_SCHEMA.COLUMNS 
WHERE TABLE_NAME = 'YourTableName'

& is always evaluated in a string context, while + may not concatenate if one of the operands is no string:

"1" + "2" => "12"
"1" + 2   => 3
1 + "2"   => 3
"a" + 2   => type mismatch

This is simply a subtle source of potential bugs and therefore should be avoided. & always means "string concatenation", even if its arguments are non-strings:

"1" & "2" => "12"
"1" &  2  => "12"
 1  & "2" => "12"
 1  &  2  => "12"
"a" &  2  => "a2"

                            var delim = sAddr.indexOf('%') // drop ip6 zone suffix
                            if (delim < 0) {
                                return sAddr.toUpperCase()

                                return sAddr.substring(0, delim).toUpperCase()
                            }
                        }
                    }
                }
            }
        }
    } catch (e: java.lang.Exception) { }
    return ""
}

You could also use the __getitem__ method combined with map like the following:

L = ['a', 'b', 'c', 'd', 'e', 'f', 'g', 'h']
Idx = [0, 3, 7]
res = list(map(L.__getitem__, Idx))
print(res)
# ['a', 'd', 'h']

Try this

myApp.config(['$httpProvider', function($httpProvider) {
        $httpProvider.defaults.useXDomain = true;
        delete $httpProvider.defaults.headers.common['X-Requested-With'];
    }
]);

Just setting useXDomain = true is not enough. AJAX request are also send with the X-Requested-With header, which indicate them as being AJAX. Removing the header is necessary, so the server is not rejecting the incoming request.

Simply use the following:

IF((SELECT count(*) FROM table)=0)
BEGIN

....

END

The code snippet:

spyOn(myOtherService, "makeRemoteCallReturningPromise").and.callFake(function() {
    var deferred = $q.defer();
    deferred.resolve('Remote call result');
    return deferred.promise;
});

Can be written in a more concise form:

spyOn(myOtherService, "makeRemoteCallReturningPromise").and.returnValue(function() {
    return $q.resolve('Remote call result');
});

If you can create your sql statement dynamically you can do following workaround:

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(", (?, ?)");
}

myStatement = myConnection.prepareStatement(mySql.toString());

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

Single Buffer

If you have a single Buffer you can use its toString method that will convert all or part of the binary contents to a string using a specific encoding. It defaults to utf8 if you don't provide a parameter, but I've explicitly set the encoding in this example.

var req = http.request(reqOptions, function(res) {
    ...

    res.on('data', function(chunk) {
        var textChunk = chunk.toString('utf8');
        // process utf8 text chunk
    });
});

Streamed Buffers

If you have streamed buffers like in the question above where the first byte of a multi-byte UTF8-character may be contained in the first Buffer (chunk) and the second byte in the second Buffer then you should use a StringDecoder. :

var StringDecoder = require('string_decoder').StringDecoder;

var req = http.request(reqOptions, function(res) {
    ...
    var decoder = new StringDecoder('utf8');

    res.on('data', function(chunk) {
        var textChunk = decoder.write(chunk);
        // process utf8 text chunk
    });
});

This way bytes of incomplete characters are buffered by the StringDecoder until all required bytes were written to the decoder.

I'm on Windows and I couldn't get any of this stuff to work. I kept getting errors about files being in the way. This worked though:

cd %APPDATA%\nvm\v8.10.0           # or whatever version you're using
mv npm npm-old
mv npm.cmd npm-old.cmd
cd node_modules\
mv npm npm-old
cd npm-old\bin
node npm-cli.js i -g npm@latest

cd %APPDATA%\nvm\v8.10.0 # or whatever version you're using
rm npm-old
rm npm-old.cmd
cd node_modules\
rm -rf npm-old

And boom, I'm back in business.

Date date = new Date();
SimpleDateFormat sdf = new SimpleDateFormat("yyyy/MM/dd HH:mm");
System.out.println(sdf.format(date));

useComponentWillMount hook

export const useComponentWillMount = (func) => {
    const willMount = useRef(true)

    if (willMount.current) func()

    willMount.current = false
}

// or
export const useComponentWillMount = (func) => {
    useMemo(func, [])
}

Discussion

In class components componentWillMount is considered legacy (source 1, source2). However, this shouldn't apply to functional components and a hook based solution. Class component componentWillMount is deprecated since it might run more than once, and there is an alternative - using the constructor. Those considerations aren't relevant for a functional component.

My experience is that such a hook could be a saver when timing/sequence is critical. I'm interested to know what is your use case - comments are welcome.

useComponentDidMount hook

Alternatively, use componentDidMount hook.

const useComponentDidMount = func => useEffect(func, []);

It will run only once, after component has mounted(initial render to the dom).

Demo

const Component = (props) => {
  useComponentWillMount(() => console.log("Runs only once before component mounts"));
  useComponentDidMount(() => console.log("Runs only once after component mounts"));
  ...

  return (
    <div>{...}</div>
  );
}

Full Demo

I put together a little test here:

\documentclass[10pt,twocolumn]{article}

\title{Article Title}
\author{
    First Author\\
    Department\\
    school\\
    email@edu
  \and
    Second Author\\
    Department\\
    school\\
    email@edu
    \and
    Third Author\\
    Department\\
    school\\
    email@edu
    \and
    Fourth Author\\
    Department\\
    school\\
    email@edu
}
\date{\today}

\begin{document}

\maketitle

\begin{abstract}
\ldots
\end{abstract}

\section{Introduction}
\ldots

\end{document}

Things to note, the title, author and date fields are declared before \begin{document}. Also, the multicol package is likely unnecessary in this case since you have declared twocolumn in the document class.

This example puts all four authors on the same line, but if your authors have longer names, departments or emails, this might cause it to flow over onto another line. You might be able to change the font sizes around a little bit to make things fit. This could be done by doing something like {\small First Author}. Here's a more detailed article on \LaTeX font sizes:

https://engineering.purdue.edu/ECN/Support/KB/Docs/LaTeXChangingTheFont

To italicize you can use {\it First Name} or \textit{First Name}.

Be careful though, if the document is meant for publication often times journals or conference proceedings have their own formatting guidelines so font size trickery might not be allowed.

Since Steve Tjoa's answer always pops up first and mostly lonely when I search for multiple y-axes at Google, I decided to add a slightly modified version of his answer. This is the approach from this matplotlib example.

Reasons:

• His modules sometimes fail for me in unknown circumstances and cryptic intern errors.
• I don't like to load exotic modules I don't know (mpl_toolkits.axisartist, mpl_toolkits.axes_grid1).
• The code below contains more explicit commands of problems people often stumble over (like single legend for multiple axes, using viridis, ...) rather than implicit behavior.

import matplotlib.pyplot as plt 

# Create figure and subplot manually
# fig = plt.figure()
# host = fig.add_subplot(111)

# More versatile wrapper
fig, host = plt.subplots(figsize=(8,5)) # (width, height) in inches
# (see https://matplotlib.org/3.3.3/api/_as_gen/matplotlib.pyplot.subplots.html)
    
par1 = host.twinx()
par2 = host.twinx()
    
host.set_xlim(0, 2)
host.set_ylim(0, 2)
par1.set_ylim(0, 4)
par2.set_ylim(1, 65)
    
host.set_xlabel("Distance")
host.set_ylabel("Density")
par1.set_ylabel("Temperature")
par2.set_ylabel("Velocity")

color1 = plt.cm.viridis(0)
color2 = plt.cm.viridis(0.5)
color3 = plt.cm.viridis(.9)

p1, = host.plot([0, 1, 2], [0, 1, 2],    color=color1, label="Density")
p2, = par1.plot([0, 1, 2], [0, 3, 2],    color=color2, label="Temperature")
p3, = par2.plot([0, 1, 2], [50, 30, 15], color=color3, label="Velocity")

lns = [p1, p2, p3]
host.legend(handles=lns, loc='best')

# right, left, top, bottom
par2.spines['right'].set_position(('outward', 60))

# no x-ticks                 
par2.xaxis.set_ticks([])

# Sometimes handy, same for xaxis
#par2.yaxis.set_ticks_position('right')

# Move "Velocity"-axis to the left
# par2.spines['left'].set_position(('outward', 60))
# par2.spines['left'].set_visible(True)
# par2.yaxis.set_label_position('left')
# par2.yaxis.set_ticks_position('left')

host.yaxis.label.set_color(p1.get_color())
par1.yaxis.label.set_color(p2.get_color())
par2.yaxis.label.set_color(p3.get_color())

# Adjust spacings w.r.t. figsize
fig.tight_layout()
# Alternatively: bbox_inches='tight' within the plt.savefig function 
#                (overwrites figsize)

# Best for professional typesetting, e.g. LaTeX
plt.savefig("pyplot_multiple_y-axis.pdf")
# For raster graphics use the dpi argument. E.g. '[...].png", dpi=200)'

Typically sites that do this by loading content via ajax and listening to the readystatechanged event to update the DOM with a loading GIF or the content.

How are you currently loading your content?

The code would be similar to this:

function load(url) {
    // display loading image here...
    document.getElementById('loadingImg').visible = true;
    // request your data...
    var req = new XMLHttpRequest();
    req.open("POST", url, true);

    req.onreadystatechange = function () {
        if (req.readyState == 4 && req.status == 200) {
            // content is loaded...hide the gif and display the content...
            if (req.responseText) {
                document.getElementById('content').innerHTML = req.responseText;
                document.getElementById('loadingImg').visible = false;
            }
        }
    };
    request.send(vars);
}

There are plenty of 3rd party javascript libraries that may make your life easier, but the above is really all you need.

Try listening for events in the parent document and passing the event to a handler in the iframe document.

Problem

No, Media Queries cannot be used in this way

<span style="@media (...) { ... }"></span>

Solution

But if you want provided a specific behavior usable on the fly AND responsive, you can use the style markup and not the attribute.

e.i.

<style scoped>
.on-the-fly-behavior {
    background-image: url('particular_ad.png'); 
}
@media (max-width: 300px) {
    .on-the-fly-behavior {
        background-image: url('particular_ad_small.png');
    }
}
</style>
<span class="on-the-fly-behavior"></span>

See the code working in live on CodePen

In my Blog for example, I inject a <style> markup in <head> just after <link> declaration for CSS and it's contain the content of a textarea provided beside of real content textarea for create extra-class on the fly when I wrote an artitle.

Note : the scoped attribute is a part of HTML5 specification. If you do not use it, the validator will blame you but browsers currently not support the real purpose : scoped the content of <style> only on immediatly parent element and that element's child elements. Scoped is not mandatory if the <style> element is in <head> markup.

UPDATE: I advice to always use rules in the mobile first way so previous code should be:

<style scoped>
/* 0 to 299 */
.on-the-fly-behavior {
    background-image: url('particular_ad_small.png'); 
}
/* 300 to X */
@media (min-width: 300px) { /* or 301 if you want really the same as previously.  */
    .on-the-fly-behavior {   
        background-image: url('particular_ad.png');
    }
}
</style>
<span class="on-the-fly-behavior"></span>

If you want to return a char* from a function, make sure you malloc() it. Stack initialized character arrays make no sense in returning, as accessing them after returning from that function is undefined behavior.

change it to

char* createStr() {
    char char1= 'm';
    char char2= 'y';
    char *str = malloc(3 * sizeof(char));
    if(str == NULL) return NULL;
    str[0] = char1;
    str[1] = char2;
    str[2] = '\0';
    return str;
}

In XCode 10.1, I had to set "Library Search Paths" to something like $(PROJECT_DIR)/.../path/to/your/library

You can do this with the ImageMagick extension. I'm guessing that the combineImages() method will do what you want.

Very late to the thread, but a technique I've used, pre-Angular, is to take advantage of JSON and the flexibility of JS to dynamically reference collection keys, and use inalienable facts of the environment (host server name, current browser language, etc.) as inputs to selectively discriminate/prefer suffixed key names within a JSON data structure.

This provides not merely deploy-environment context (per OP) but any arbitrary context (such as language) to provide i18n or any other variance required simultaneously, and (ideally) within a single configuration manifest, without duplication, and readably obvious.

IN ABOUT 10 LINES VANILLA JS

Overly-simplified but classic example: An API endpoint base URL in a JSON-formatted properties file that varies per environment where (natch) the host server will also vary:

    ...
    'svcs': {
        'VER': '2.3',
        'API@localhost': 'http://localhost:9090/',
        '[email protected]': 'https://www.uat.productionwebsite.com:9090/res/',
        '[email protected]': 'https://www.productionwebsite.com:9090/api/res/'
    },
    ...

A key to the discrimination function is simply the server hostname in the request.

This, naturally, can be combined with an additional key based on the user's language settings:

    ...
    'app': {
        'NAME': 'Ferry Reservations',
        'NAME@fr': 'Réservations de ferry',
        'NAME@de': 'Fähren Reservierungen'
    },
    ...

The scope of the discrimination/preference can be confined to individual keys (as above) where the "base" key is only overwritten if there's a matching key+suffix for the inputs to the function -- or an entire structure, and that structure itself recursively parsed for matching discrimination/preference suffixes:

    'help': {
        'BLURB': 'This pre-production environment is not supported. Contact Development Team with questions.',
        'PHONE': '808-867-5309',
        'EMAIL': '[email protected]'
    },
    '[email protected]': {
        'BLURB': 'Please contact Customer Service Center',
        'BLURB@fr': 'S\'il vous plaît communiquer avec notre Centre de service à la clientèle',
        'BLURB@de': 'Bitte kontaktieren Sie unseren Kundendienst!!1!',
        'PHONE': '1-800-CUS-TOMR',
        'EMAIL': '[email protected]'
    },

SO, if a visiting user to the production website has German (de) language preference setting, the above configuration would collapse to:

    'help': {
        'BLURB': 'Bitte kontaktieren Sie unseren Kundendienst!!1!',
        'PHONE': '1-800-CUS-TOMR',
        'EMAIL': '[email protected]'
    },

What does such a magical preference/discrimination JSON-rewriting function look like? Not much:

// prefer(object,suffix|[suffixes]) by/par/durch storsoc
// prefer({ a: 'apple', a@env: 'banana', b: 'carrot' },'env') -> { a: 'banana', b: 'carrot' }
function prefer(o,sufs) {
    for (var key in o) {
        if (!o.hasOwnProperty(key)) continue; // skip non-instance props
        if(key.split('@')[1]) { // suffixed!
            // replace root prop with the suffixed prop if among prefs
            if(o[key] && sufs.indexOf(key.split('@')[1]) > -1) o[key.split('@')[0]] = JSON.parse(JSON.stringify(o[key]));

            // and nuke the suffixed prop to tidy up
            delete o[key];

            // continue with root key ...
            key = key.split('@')[0];
        }

        // ... in case it's a collection itself, recurse it!
        if(o[key] && typeof o[key] === 'object') prefer(o[key],sufs);

    };
};

In our implementations, which include Angular and pre-Angular websites, we simply bootstrap the configuration well ahead of other resource calls by placing the JSON within a self-executing JS closure, including the prefer() function, and fed basic properties of hostname and language-code (and accepts any additional arbitrary suffixes you might need):

(function(prefs){ var props = {
    'svcs': {
        'VER': '2.3',
        'API@localhost': 'http://localhost:9090/',
        '[email protected]': 'https://www.uat.productionwebsite.com:9090/res/',
        '[email protected]': 'https://www.productionwebsite.com:9090/api/res/'
    },
    ...
    /* yadda yadda moar JSON und bisque */

    function prefer(o,sufs) {
        // body of prefer function, broken for e.g.
    };

    // convert string and comma-separated-string to array .. and process it
    prefs = [].concat( ( prefs.split ? prefs.split(',') : prefs ) || []);
    prefer(props,prefs);
    window.app_props = JSON.parse(JSON.stringify(props));
})([location.hostname, ((window.navigator.userLanguage || window.navigator.language).split('-')[0])  ] );

A pre-Angular site would now have a collapsed (no @ suffixed keys) window.app_props to refer to.

An Angular site, as a bootstrap/init step, simply copies the dead-dropped props object into $rootScope, and (optionally) destroys it from global/window scope

app.constant('props',angular.copy(window.app_props || {})).run( function ($rootScope,props) { $rootScope.props = props; delete window.app_props;} );

to be subsequently injected into controllers:

app.controller('CtrlApp',function($log,props){ ... } );

or referred to from bindings in views:

<span>{{ props.help.blurb }} {{ props.help.email }}</span>

Caveats? The @ character is not valid JS/JSON variable/key naming, but so far accepted. If that's a deal-breaker, substitute for any convention you like, such as "__" (double underscore) as long as you stick to it.

The technique could be applied server-side, ported to Java or C# but your efficiency/compactness may vary.

Alternately, the function/convention could be part of your front-end compile script, so that the full gory all-environment/all-language JSON is never transmitted over the wire.

UPDATE

We've evolved usage of this technique to allow multiple suffixes to a key, to avoid being forced to use collections (you still can, as deeply as you want), and as well to honor the order of the preferred suffixes.

Example (also see working jsFiddle):

var o = { 'a':'apple', 'a@dev':'apple-dev', 'a@fr':'pomme',
          'b':'banana', 'b@fr':'banane', 'b@dev&fr':'banane-dev',
          'c':{ 'o':'c-dot-oh', 'o@fr':'c-point-oh' }, 'c@dev': { 'o':'c-dot-oh-dev', 'o@fr':'c-point-oh-dev' } };

/*1*/ prefer(o,'dev');        // { a:'apple-dev', b:'banana',     c:{o:'c-dot-oh-dev'}   }
/*2*/ prefer(o,'fr');         // { a:'pomme',     b:'banane',     c:{o:'c-point-oh'}     }
/*3*/ prefer(o,'dev,fr');     // { a:'apple-dev', b:'banane-dev', c:{o:'c-point-oh-dev'} }
/*4*/ prefer(o,['fr','dev']); // { a:'pomme',     b:'banane-dev', c:{o:'c-point-oh-dev'} }
/*5*/ prefer(o);              // { a:'apple',     b:'banana',     c:{o:'c-dot-oh'}       }

1/2 (basic usage) prefers '@dev' keys, discards all other suffixed keys

3 prefers '@dev' over '@fr', prefers '@dev&fr' over all others

4 (same as 3 but prefers '@fr' over '@dev')

5 no preferred suffixes, drops ALL suffixed properties

It accomplishes this by scoring each suffixed property and promoting the value of a suffixed property to the non-suffixed property when iterating over the properties and finding a higher-scored suffix.

Some efficiencies in this version, including removing dependence on JSON to deep-copy, and only recursing into objects that survive the scoring round at their depth:

function prefer(obj,suf) {
    function pr(o,s) {
        for (var p in o) {
            if (!o.hasOwnProperty(p) || !p.split('@')[1] || p.split('@@')[1] ) continue; // ignore: proto-prop OR not-suffixed OR temp prop score
            var b = p.split('@')[0]; // base prop name
            if(!!!o['@@'+b]) o['@@'+b] = 0; // +score placeholder
            var ps = p.split('@')[1].split('&'); // array of property suffixes
            var sc = 0; var v = 0; // reset (running)score and value
            while(ps.length) {
                // suffix value: index(of found suffix in prefs)^10
                v = Math.floor(Math.pow(10,s.indexOf(ps.pop())));
                if(!v) { sc = 0; break; } // found suf NOT in prefs, zero score (delete later)
                sc += v;
            }
            if(sc > o['@@'+b]) { o['@@'+b] = sc; o[b] = o[p]; } // hi-score! promote to base prop
            delete o[p];
        }
        for (var p in o) if(p.split('@@')[1]) delete o[p]; // remove scores
        for (var p in o) if(typeof o[p] === 'object') pr(o[p],s); // recurse surviving objs
    }
    if( typeof obj !== 'object' ) return; // validate
    suf = ( (suf || suf === 0 ) && ( suf.length || suf === parseFloat(suf) ) ? suf.toString().split(',') : []); // array|string|number|comma-separated-string -> array-of-strings
    pr(obj,suf.reverse());
}

Just an idea, if you know the categories, as small, medium, and large mentioned above...

At the bottom of the sheet, make 3 rows that only say small, medium, and large, change the font to white, and then sort so that it alphabetizes, placing a blank row between each section.

You can just use x.shape, in order to measure tensor's x dimensions

Do everything suggested by ziesemer.

You may also want to remove from the registry:

HKEY_LOCAL_MACHINE\SOFTWARE\ODBC\ODBCINST.INI\<any Ora* drivers> keys     

HKEY_LOCAL_MACHINE\SOFTWARE\ODBC\ODBCINST.INI\ODBC Drivers<any Ora* driver> values

So they no longer appear in the "ODBC Drivers that are installed on your system" in ODBC Data Source Administrator

Not really sure what you mean by no "function"

Obviously, change ECHO to SET to set the variables rather thon ECHOing them...

https://github.com/blueimp/JavaScript-Load-Image is a modern javascript library that can not only extract the exif orientation flag - it can also correctly mirror/rotate JPEG images on the client side.

I just solved the same problem with this library: JS Client-Side Exif Orientation: Rotate and Mirror JPEG Images

Below code is nice.. It was given by somebody else named aaronbd in this forum

<?php

$conn = new mysqli('localhost', 'username', 'password', 'database') 
or die ('Cannot connect to db');

    $result = $conn->query("select id, name from table");

    echo "<html>";
    echo "<body>";
    echo "<select name='id'>";

    while ($row = $result->fetch_assoc()) {

                  unset($id, $name);
                  $id = $row['id'];
                  $name = $row['name']; 
                  echo '<option value="'.$id.'">'.$name.'</option>';

One way

// join type can be inner, left, right, fullouter
val mergedDf = df1.join(df2, Seq("keyCol"), "inner")
// keyCol can be multiple column names seperated by comma
val mergedDf = df1.join(df2, Seq("keyCol1", "keyCol2"), "left")

Another way

import spark.implicits._ 
val mergedDf = df1.as("d1").join(df2.as("d2"), ($"d1.colName" === $"d2.colName"))
// to select specific columns as output
val mergedDf = df1.as("d1").join(df2.as("d2"), ($"d1.colName" === $"d2.colName")).select($"d1.*", $"d2.anotherColName")

So I had problems installing vtk under windows (as I use python 3.7 there is no binary available so far just for older python versions pip install vtk is not working)

I did wrote python in my cmd:

Python 3.7.3 on win32

So I now know I have python 3.7.3 runing on a 32 bit.

I then downloaded the correct wheel at VTK-8.2.0-cp37-cp37m-win32.whl

Next I instlled that wheel:

pip install VTK-8.2.0-cp37-cp37m-win32.whl

Then I tested it and it worked:

python
import vtk

To simulate an event, you could to use trigger JQuery functionnality.

$('#foo').on('click', function() {
      alert($(this).text());
    });
$('#foo').trigger('click');

hope you are doing well. you can use my code to crop image.you just have to make a class and use this class into your XMl and java classes. Crop image. you can crop your selected image into circle and square into many of option. hope fully it will works for you.because this is totally manageable for you and you can change it according to you.

enjoy your work :)

Well, it costed me 2 days to figure out the problem. In short, by default you shall just keep the max version to be the highest level you had downloaded, says, Level 23 (Android M) for my case.

otherwise you will get these errors. You have to go to project properties of both your project and appcompat to change the target version.

sigh.

A server socket listens on a single port. All established client connections on that server are associated with that same listening port on the server side of the connection. An established connection is uniquely identified by the combination of client-side and server-side IP/Port pairs. Multiple connections on the same server can share the same server-side IP/Port pair as long as they are associated with different client-side IP/Port pairs, and the server would be able to handle as many clients as available system resources allow it to.

On the client-side, it is common practice for new outbound connections to use a random client-side port, in which case it is possible to run out of available ports if you make a lot of connections in a short amount of time.

The recommended way to create random integers with NumPy these days is to use numpy.random.Generator.integers. (documentation)

import numpy as np
import pandas as pd

rng = np.random.default_rng()
df = pd.DataFrame(rng.integers(0, 100, size=(100, 4)), columns=list('ABCD'))
df
----------------------
      A    B    C    D
 0   58   96   82   24
 1   21    3   35   36
 2   67   79   22   78
 3   81   65   77   94
 4   73    6   70   96
... ...  ...  ...  ...
95   76   32   28   51
96   33   68   54   77
97   76   43   57   43
98   34   64   12   57
99   81   77   32   50
100 rows × 4 columns

You can use the pandas.DataFrame.quantile() function, as shown below.

import pandas as pd
import random

A = [ random.randint(0,100) for i in range(10) ]
B = [ random.randint(0,100) for i in range(10) ]

df = pd.DataFrame({ 'field_A': A, 'field_B': B })
df
#    field_A  field_B
# 0       90       72
# 1       63       84
# 2       11       74
# 3       61       66
# 4       78       80
# 5       67       75
# 6       89       47
# 7       12       22
# 8       43        5
# 9       30       64

df.field_A.mean()   # Same as df['field_A'].mean()
# 54.399999999999999

df.field_A.median() 
# 62.0

# You can call `quantile(i)` to get the i'th quantile,
# where `i` should be a fractional number.

df.field_A.quantile(0.1) # 10th percentile
# 11.9

df.field_A.quantile(0.5) # same as median
# 62.0

df.field_A.quantile(0.9) # 90th percentile
# 89.10000000000001

Using yaml folded style. The indention in each line will be ignored. A line break will be inserted at the end.

Key: >
  This is a very long sentence
  that spans several lines in the YAML
  but which will be rendered as a string
  with only a single carriage return appended to the end.

http://symfony.com/doc/current/components/yaml/yaml_format.html

You can use the "block chomping indicator" to eliminate the trailing line break, as follows:

Key: >-
  This is a very long sentence
  that spans several lines in the YAML
  but which will be rendered as a string
  with NO carriage returns.

In either case, each line break is replaced by a space.

There are other control tools available as well (for controlling indentation for example).

See https://yaml-multiline.info/

The short version can be like this:

const diff = (a, b) => b.filter((i) => a.indexOf(i) === -1);

result:

diff(['a', 'b'], ['a', 'b', 'c', 'd']);

["c", "d"]

Being unhappy with the available solution, I adopted nu774's script to add security and make it easier to setup and use. The project is available on Github

To use it, just download cygwin-sudo.py and run it via python3 cygwin-sudo.py **yourcommand**.

You can set up an alias for convenience:

alias sudo="python3 /path-to-cygwin-sudo/cygwin-sudo.py"

Gradle Build Tools 2.2.0+ - The closest the NDK has ever come to being called 'magic'

In trying to avoid experimental and frankly fed up with the NDK and all its hackery I am happy that 2.2.x of the Gradle Build Tools came out and now it just works. The key is the externalNativeBuild and pointing ndkBuild path argument at an Android.mk or change ndkBuild to cmake and point the path argument at a CMakeLists.txt build script.

android {
    compileSdkVersion 19
    buildToolsVersion "25.0.2"

    defaultConfig {
        minSdkVersion 19
        targetSdkVersion 19

        ndk {
            abiFilters 'armeabi', 'armeabi-v7a', 'x86'
        }

        externalNativeBuild {
            cmake {
                cppFlags '-std=c++11'
                arguments '-DANDROID_TOOLCHAIN=clang',
                        '-DANDROID_PLATFORM=android-19',
                        '-DANDROID_STL=gnustl_static',
                        '-DANDROID_ARM_NEON=TRUE',
                        '-DANDROID_CPP_FEATURES=exceptions rtti'
            }
        }
    }

    externalNativeBuild {
        cmake {
             path 'src/main/jni/CMakeLists.txt'
        }
        //ndkBuild {
        //   path 'src/main/jni/Android.mk'
        //}
    }
}

For much more detail check Google's page on adding native code.

After this is setup correctly you can ./gradlew installDebug and off you go. You will also need to be aware that the NDK is moving to clang since gcc is now deprecated in the Android NDK.

Android Studio Clean and Build Integration - DEPRECATED

The other answers do point out the correct way to prevent the automatic creation of Android.mk files, but they fail to go the extra step of integrating better with Android Studio. I have added the ability to actually clean and build from source without needing to go to the command-line. Your local.properties file will need to have ndk.dir=/path/to/ndk

apply plugin: 'com.android.application'

android {
    compileSdkVersion 14
    buildToolsVersion "20.0.0"

    defaultConfig {
        applicationId "com.example.application"
        minSdkVersion 14
        targetSdkVersion 14

        ndk {
            moduleName "YourModuleName"
        }
    }

    sourceSets.main {
        jni.srcDirs = [] // This prevents the auto generation of Android.mk
        jniLibs.srcDir 'src/main/libs' // This is not necessary unless you have precompiled libraries in your project.
    }

    task buildNative(type: Exec, description: 'Compile JNI source via NDK') {
        def ndkDir = android.ndkDirectory
        commandLine "$ndkDir/ndk-build",
                '-C', file('src/main/jni').absolutePath, // Change src/main/jni the relative path to your jni source
                '-j', Runtime.runtime.availableProcessors(),
                'all',
                'NDK_DEBUG=1'
    }

    task cleanNative(type: Exec, description: 'Clean JNI object files') {
        def ndkDir = android.ndkDirectory
        commandLine "$ndkDir/ndk-build",
                '-C', file('src/main/jni').absolutePath, // Change src/main/jni the relative path to your jni source
                'clean'
    }

    clean.dependsOn 'cleanNative'

    tasks.withType(JavaCompile) {
        compileTask -> compileTask.dependsOn buildNative
    }
}

dependencies {
    compile 'com.android.support:support-v4:20.0.0'
}

The src/main/jni directory assumes a standard layout of the project. It should be the relative from this build.gradle file location to the jni directory.

Gradle - for those having issues

Also check this Stack Overflow answer.

It is really important that your gradle version and general setup are correct. If you have an older project I highly recommend creating a new one with the latest Android Studio and see what Google considers the standard project. Also, use gradlew. This protects the developer from a gradle version mismatch. Finally, the gradle plugin must be configured correctly.

And you ask what is the latest version of the gradle plugin? Check the tools page and edit the version accordingly.

Final product - /build.gradle

// Top-level build file where you can add configuration options common to all sub-projects/modules.

// Running 'gradle wrapper' will generate gradlew - Getting gradle wrapper working and using it will save you a lot of pain.
task wrapper(type: Wrapper) {
    gradleVersion = '2.2'
}

// Look Google doesn't use Maven Central, they use jcenter now.
buildscript {
    repositories {
        jcenter()
    }
    dependencies {
        classpath 'com.android.tools.build:gradle:1.2.0'

        // NOTE: Do not place your application dependencies here; they belong
        // in the individual module build.gradle files
    }
}

allprojects {
    repositories {
        jcenter()
    }
}

Make sure gradle wrapper generates the gradlew file and gradle/wrapper subdirectory. This is a big gotcha.

ndkDirectory

This has come up a number of times, but android.ndkDirectory is the correct way to get the folder after 1.1. Migrating Gradle Projects to version 1.0.0. If you're using an experimental or ancient version of the plugin your mileage may vary.

Switch the order of the functions or do a forward declaration of the writefiles function and it will work I think.

I've built an open-source SDK called Kickflip to make streaming video from Android a painless experience.

The SDK demonstrates use of Android 4.3's MediaCodec API to direct the device hardware encoder's packets directly to FFmpeg for RTMP (with librtmp) or HLS streaming of H.264 / AAC. It also demonstrates realtime OpenGL Effects (titling, chroma key, fades) and background recording.

Thanks SO, and especially, fadden.

your <%= //map.size() %> doesnt simply work because it should have been

<% //= map.size() %>

Given an answer as high voted and views. I did find the answer with mixed of here and other links.

I have a scenario where all patient-related menu is disabled if a patient is not selected. (Refer link - how to disable a li tag using JavaScript)

//css
.disabled{
    pointer-events:none;
    opacity:0.4;
}
// jqvery
$("li a").addClass('disabled');
// remove .disabled when you are done

So rather than write long code, I found an interesting solution via CSS.

$(document).ready(function () {_x000D_
 var PatientId ; _x000D_
 //var PatientId =1;  //remove to test enable i.e. patient selected_x000D_
 if (typeof PatientId == "undefined" || PatientId == "" || PatientId == 0 || PatientId == null) {_x000D_
  console.log(PatientId);_x000D_
  $("#dvHeaderSubMenu a").each(function () {   _x000D_
   $(this).addClass('disabled');_x000D_
  });  _x000D_
  return;_x000D_
 }_x000D_
})

.disabled{_x000D_

The microsoft telnet.exe is not scriptable without using another script (which needs keyboard focus), as shown in another answer to this question, but there is a free

Telnet Scripting Tool v.1.0 by Albert Yale

that you can google for and which is both scriptable and loggable and can be launched from a batch file without needing keyboard focus.

The problem with telnet.exe and a second script when keyboard focus is being used is that if someone is using the computer at the time the script runs, then it is highly likely that the script will fail due to mouse clicks and keyboard use at that moment in time.

Using this source code you can upload multiple file like google one by one through ajax. Also you can see the uploading progress

HTML

 <input type="file" id="multiupload" name="uploadFiledd[]" multiple >
 <button type="button" id="upcvr" class="btn btn-primary">Start Upload</button>
 <div id="uploadsts"></div>

Javascript

    <script>

    function uploadajax(ttl,cl){

    var fileList = $('#multiupload').prop("files");
    $('#prog'+cl).removeClass('loading-prep').addClass('upload-image');

    var form_data =  "";

    form_data = new FormData();
    form_data.append("upload_image", fileList[cl]);


    var request = $.ajax({
              url: "upload.php",
              cache: false,
              contentType: false,
              processData: false,
              async: true,
              data: form_data,
              type: 'POST', 
              xhr: function() {  
                  var xhr = $.ajaxSettings.xhr();
                  if(xhr.upload){ 
                  xhr.upload.addEventListener('progress', function(event){
                      var percent = 0;
                      if (event.lengthComputable) {
                          percent = Math.ceil(event.loaded / event.total * 100);
                      }
                      $('#prog'+cl).text(percent+'%') 
                   }, false);
                 }
                 return xhr;
              },
              success: function (res, status) {
                  if (status == 'success') {
                      percent = 0;
                      $('#prog' + cl).text('');
                      $('#prog' + cl).text('--Success: ');
                      if (cl < ttl) {
                          uploadajax(ttl, cl + 1);
                      } else {
                          alert('Done');
                      }
                  }
              },
              fail: function (res) {
                  alert('Failed');
              }    
          })
    }

    $('#upcvr').click(function(){
        var fileList = $('#multiupload').prop("files");
        $('#uploadsts').html('');
        var i;
        for ( i = 0; i < fileList.length; i++) {
            $('#uploadsts').append('<p class="upload-page">'+fileList[i].name+'<span class="loading-prep" id="prog'+i+'"></span></p>');
            if(i == fileList.length-1){
                uploadajax(fileList.length-1,0);
            }
         }
    });
    </script>

PHP

upload.php
    move_uploaded_file($_FILES["upload_image"]["tmp_name"],$_FILES["upload_image"]["name"]);

When the other solutions did not work for you (Changing JVM version on Compiler settings and adding jvmTarget into your build.gradle), because of your .iml files trying to force their configurations you can change the target platform from Project Settings.

• Open File > Project Structure
• Go to Facets under Project Settings
  • If it is empty then click on the small + button
• Click on your Kotlin module/modules
• Change the Target Platform to JVM 1.8 (also it's better to check Use project settings option)

Check out here for dump. It seems there is a dump function in the library sqlite3.

The ORA-01722 error is pretty straightforward. According to Tom Kyte:

We've attempted to either explicity or implicity convert a character string to a number and it is failing.

However, where the problem is is often not apparent at first. This page helped me to troubleshoot, find, and fix my problem. Hint: look for places where you are explicitly or implicitly converting a string to a number. (I had NVL(number_field, 'string') in my code.)

From all I have read you cannot do exactly what you want without javascript. If you float left before text

<div style="float:left;">widget</div> here is some CONTENT, etc.

Your content wraps as expected. But your widget is in the top left. If you instead put the float after the content

here is some CONTENT, etc. <div style="float:left;">widget</div>

Then your content will wrap the last line to the right of the widget if the last line of content can fit to the right of the widget, otherwise no wrapping is done. To make borders and backgrounds actually include the floated area in the previous example, most people add:

here is some CONTENT, etc. <div style="float:left;">widget</div><div style="clear:both;"></div>

In your question you are using bootstrap which just adds row-fluid::after { content: ""} which resolves the border/background issue.

Moving your content up will give you the one line wrap : http://jsfiddle.net/jJNPY/34/

  <div class="container-fluid">
  <div class="row-fluid">
    <div class="offset1 span8 pull-right">
    ... Widget 1...
    </div>
    .... a lot of content ....
    <div class="span8" style="margin-left: 0;">
    ... Widget 2...
    </div>


  </div>

</div><!--/.fluid-container-->

With ES6 you can simply do:

 for(const element of Results) {
      element.Active = "false";
 }

In my case (php page on OVH mutualisé server) enctype="text/plain" does not work ($_POST and corresponding $_REQUEST is empty), the other examples below work. `

<form action="?" method="post">
<!-- in this case, my google chrome 45.0.2454.101 uses -->
<!--     Content-Type:application/x-www-form-urlencoded -->
    <input name="say" value="Hi">
    <button>Send my greetings</button>
</form>

<form action="?" method="post" enctype="application/x-www-form-urlencoded">
    <input name="say" value="Hi">
    <button>Send my application/x-www-form-urlencoded greetings</button>
</form>

<form action="?" method="post"  enctype="multipart/form-data">
    <input name="say" value="Hi">
    <button>Send my multipart/form-data greetings</button>
</form>

<form action="?" method="post" enctype="text/plain"><!-- not working -->
    <input name="say" value="Hi">
    <button>Send my text/plain greetings</button>
</form>

`

More here: method="post" enctype="text/plain" are not compatible?

Assembly language has no direct means of printing anything. Your assembler may or may not come with a library that supplies such a facility, otherwise you have to write it yourself, and it will be quite a complex function. You also have to decide where to print things - in a window, on the printer? In assembler, none of this is done for you.

To get "local" yesterday in UTC.

  var now = DateTime.Now;
  var yesterday = new DateTime(now.Year, now.Month, now.Day, 0, 0, 0, DateTimeKind.Utc).AddDays(-1);

If you want to know the port number of your local host on which Mysql is running you can use this query on MySQL Command line client --

SHOW VARIABLES WHERE Variable_name = 'port';


mysql> SHOW VARIABLES WHERE Variable_name = 'port';
+---------------+-------+
| Variable_name | Value |
+---------------+-------+
| port          | 3306  |
+---------------+-------+
1 row in set (0.00 sec)

It will give you the port number on which MySQL is running.

If you want to know the hostname of your Mysql you can use this query on MySQL Command line client --

SHOW VARIABLES WHERE Variable_name = 'hostname';


mysql> SHOW VARIABLES WHERE Variable_name = 'hostname';
+-------------------+-------+
| Variable_name     | Value |
+-------------------+-------+
| hostname          | Dell  |
+-------------------+-------+
1 row in set (0.00 sec)

It will give you the hostname for mysql.

If you want to know the username of your Mysql you can use this query on MySQL Command line client --

select user();   


mysql> select user();
+----------------+
| user()         |
+----------------+
| root@localhost |
+----------------+
1 row in set (0.00 sec)

It will give you the username for mysql.

This should work: use a back slash and put a double quote

"UPDATE my_table SET row =\"hi, my name's tim.\";
