My guess is that you've got something in method1 which wraps one exception in another, and uses the toString() of the nested exception as the message of the wrapper. I suggest you take a copy of your project, and remove as much as you can while keeping the problem, until you've got a short but complete program which demonstrates it - at which point either it'll be clear what's going on, or we'll be in a better position to help fix it.

Here's a short but complete program which demonstrates RuntimeException.getMessage() behaving correctly:

public class Test {
    public static void main(String[] args) {
        try {
            failingMethod();
        } catch (Exception e) {
            System.out.println("Error: " + e.getMessage());
        }
    }       

    private static void failingMethod() {
        throw new RuntimeException("Just the message");
    }
}

Output:

Error: Just the message

Ran into a similar issue, in that creating custom error messages for my custom exceptions make ugly code. This was my solution:

class MyRunTimeException: public std::runtime_error
{
public:
      MyRunTimeException(const std::string &filename):std::runtime_error(GetMessage(filename)) {}
private:
      static std::string GetMessage(const std::string &filename)
     {
           // Do your message formatting here. 
           // The benefit of returning std::string, is that the compiler will make sure the buffer is good for the length of the constructor call
           // You can use a local std::ostringstream here, and return os.str()
           // Without worrying that the memory is out of scope. It'll get copied
           // You also can create multiple GetMessage functions that take all sorts of objects and add multiple constructors for your exception
     }
}

This separates the logic for creating the messages. I had originally thought about overriding what(), but then you have to capture your message somewhere. std::runtime_error already has an internal buffer.

I will use horizontal stackview. It can remove the frame when the subview is hidden.

In image below, the red view is the actual container for your content and has 10pt trailing space to orange superview (ShowHideView), then just connect ShowHideView to IBOutlet and show/hide/remove it programatically.

1. This is when the view is visible/installed.

2. This is when the view is hidden/not-installed.

It happens because you have not installed the minSdkVersion or targetSdkVersion in you’re computer. I've tested it right now.

For example, if you have those lines in your Manifest.xml:

<uses-sdk
android:minSdkVersion="8"
android:targetSdkVersion="17" />

And you have installed only the API17 in your computer, it will report you an error. If you want to test it, try installing the other API version (in this case, API 8).

Even so, it's not an important error. It doesn't mean that your app is wrong.

Sorry about my expression. English is not my language. Bye!

This code works perfectly well:

 Actions builder = new Actions(driver);
 WebElement element = driver.findElement(By.linkText("Put your text here"));
 builder.moveToElement(element).build().perform();

After the mouse over, you can then go on to perform the next action you want on the revealed information

The example Java data structure in the original question does not match the description of the JSON structure in the comment.

The JSON is described as

"an array of {object with an array of {object}}".

In terms of the types described in the question, the JSON translated into a Java data structure that would match the JSON structure for easy deserialization with Gson is

"an array of {TypeDTO object with an array of {ItemDTO object}}".

But the Java data structure provided in the question is not this. Instead it's

"an array of {TypeDTO object with an array of an array of {ItemDTO object}}".

A two-dimensional array != a single-dimensional array.

This first example demonstrates using Gson to simply deserialize and serialize a JSON structure that is "an array of {object with an array of {object}}".

input.json Contents:

[
  {
    "id":1,
    "name":"name1",
    "items":
    [
      {"id":2,"name":"name2","valid":true},
      {"id":3,"name":"name3","valid":false},
      {"id":4,"name":"name4","valid":true}
    ]
  },
  {
    "id":5,
    "name":"name5",
    "items":
    [
      {"id":6,"name":"name6","valid":true},
      {"id":7,"name":"name7","valid":false}
    ]
  },
  {
    "id":8,
    "name":"name8",
    "items":
    [
      {"id":9,"name":"name9","valid":true},
      {"id":10,"name":"name10","valid":false},
      {"id":11,"name":"name11","valid":false},
      {"id":12,"name":"name12","valid":true}
    ]
  }
]

Foo.java:

import java.io.FileReader;
import java.util.ArrayList;

import com.google.gson.Gson;

public class Foo
{
  public static void main(String[] args) throws Exception
  {
    Gson gson = new Gson();
    TypeDTO[] myTypes = gson.fromJson(new FileReader("input.json"), TypeDTO[].class);
    System.out.println(gson.toJson(myTypes));
  }
}

class TypeDTO
{
  int id;
  String name;
  ArrayList<ItemDTO> items;
}

class ItemDTO
{
  int id;
  String name;
  Boolean valid;
}

This second example uses instead a JSON structure that is actually "an array of {TypeDTO object with an array of an array of {ItemDTO object}}" to match the originally provided Java data structure.

input.json Contents:

[
  {
    "id":1,
    "name":"name1",
    "items":
    [
      [
        {"id":2,"name":"name2","valid":true},
        {"id":3,"name":"name3","valid":false}
      ],
      [
        {"id":4,"name":"name4","valid":true}
      ]
    ]
  },
  {
    "id":5,
    "name":"name5",
    "items":
    [
      [
        {"id":6,"name":"name6","valid":true}
      ],
      [
        {"id":7,"name":"name7","valid":false}
      ]
    ]
  },
  {
    "id":8,
    "name":"name8",
    "items":
    [
      [
        {"id":9,"name":"name9","valid":true},
        {"id":10,"name":"name10","valid":false}
      ],
      [
        {"id":11,"name":"name11","valid":false},
        {"id":12,"name":"name12","valid":true}
      ]
    ]
  }
]

Foo.java:

import java.io.FileReader;
import java.util.ArrayList;

import com.google.gson.Gson;

public class Foo
{
  public static void main(String[] args) throws Exception
  {
    Gson gson = new Gson();
    TypeDTO[] myTypes = gson.fromJson(new FileReader("input.json"), TypeDTO[].class);
    System.out.println(gson.toJson(myTypes));
  }
}

class TypeDTO
{
  int id;
  String name;
  ArrayList<ItemDTO> items[];
}

class ItemDTO
{
  int id;
  String name;
  Boolean valid;
}

Regarding the remaining two questions:

is Gson extremely fast?

Not compared to other deserialization/serialization APIs. Gson has traditionally been amongst the slowest. The current and next releases of Gson reportedly include significant performance improvements, though I haven't looked for the latest performance test data to support those claims.

That said, if Gson is fast enough for your needs, then since it makes JSON deserialization so easy, it probably makes sense to use it. If better performance is required, then Jackson might be a better choice to use. It offers much (maybe even all) of the conveniences of Gson.

Or am I better to stick with what I've got working already?

I wouldn't. I would most always rather have one simple line of code like

TypeDTO[] myTypes = gson.fromJson(new FileReader("input.json"), TypeDTO[].class);

...to easily deserialize into a complex data structure, than the thirty lines of code that would otherwise be needed to map the pieces together one component at a time.

In Ruby 2.1 it is simple:

h.sort.to_h

If you refer the official angular docs

https://angular.io/guide/attribute-directives

There are three kinds of directives in Angular:

1. Components—directives with a template.
2. Structural directives—change the DOM layout by adding and removing DOM elements. e.g *ngIf
3. Attribute directives—change the appearance or behavior of an element, component, or another directive. e.g [ngClass].

As the Application grows we find difficulty in maintaining all these codes. For reusability purpose, we separate our logic in smart components and dumb components and we use directives (structural or attribute) to make changes in the DOM.

Try to set the port on 26, this has fixed my problem with the message "data not accepted".

Thanks to the solution provided by @yogihosting I was able to achieve similar result from schemaless columns of mysql with codes shown below:

// @params - will be bound to named query parameters
$criteria = [];
$criteria['latitude'] = '9.0285183';
$criteria['longitude'] = '7.4869546';
$criteria['distance'] = 500;
$criteria['skill'] = 'software developer';

// Get doctrine connection 
$conn = $this->getEntityManager()->getConnection();

        $sql = '
               SELECT DISTINCT m.uuid AS phone, (((acos(sin((:latitude*pi()/180)) * sin((JSON_EXTRACT(m.location, "$.latitude")*pi()/180))+cos((:latitude*pi()/180)) * 
              cos((JSON_EXTRACT(m.location, "$.latitude")*pi()/180)) * 
              cos(((:longitude - JSON_EXTRACT(m.location, "$.longitude"))*pi()/180))))*180/pi())*60*1.1515*1.609344) AS distance FROM member_profile AS m 
               INNER JOIN member_card_subscription mcs ON mcs.primary_identity = m.uuid
               WHERE mcs.end > now() AND JSON_SEARCH(m.skill_logic, "one", :skill) IS NOT NULL  AND (((acos(sin((:latitude*pi()/180)) * sin((JSON_EXTRACT(m.location, "$.latitude")*pi()/180))+cos((:latitude*pi()/180)) * 
              cos((JSON_EXTRACT(m.location, "$.latitude")*pi()/180)) * 
              cos(((:longitude - JSON_EXTRACT(m.location, "$.longitude"))*pi()/180))))*180/pi())*60*1.1515*1.609344) <= :distance ORDER BY distance
               ';
        $stmt = $conn->prepare($sql);
        $stmt->execute(['latitude'=>$criteria['latitude'], 'longitude'=>$criteria['longitude'], 'skill'=>$criteria['skill'], 'distance'=>$criteria['distance']]);
        var_dump($stmt->fetchAll());

Please note the above code snippet is using doctrine DB connection and PHP

I had the same issue for another secure page when using wget or file_get_contents. A lot of research (including some of the responses on this question) resulted in a simple solution - installing Curl and PHP-Curl - If I've understood correctly, Curl has the Root CA for Comodo which resolved the issue

Install Curl and PHP-Curl addon, then restart Apache

sudo apt-get install curl
sudo apt-get install php-curl
sudo /etc/init.d/apache2 reload

All now working.

The deduplication (to select the max T1) and the aggregation need to be done as distinct steps. I've used a CTE since I think this makes it clearer:

;WITH sumCTE
AS
(
    SELECT  Rel.t2ID, SUM(Price) price
    FROM    @t1         AS T1
    JOIN    @relation   AS Rel 
    ON      Rel.t1ID=T1.ID
    GROUP 
    BY      Rel.t2ID
)
,maxCTE
AS
(
    SELECT  Rel.t2ID, Rel.t1ID, 
            ROW_NUMBER()OVER(Partition By Rel.t2ID Order By Price DESC)As PriceList
    FROM    @t1         AS T1
    JOIN    @relation   AS Rel 
    ON      Rel.t1ID=T1.ID
)
SELECT T2.ID AS T2ID
,T2.Name as T2Name
,T2.Orders
,T1.ID AS T1ID
,T1.Name As T1Name
,sumT1.Price
FROM    @t2 AS T2
JOIN    sumCTE AS sumT1
ON      sumT1.t2ID = t2.ID
JOIN    maxCTE AS maxT1
ON      maxT1.t2ID = t2.ID
JOIN    @t1 AS T1
ON      T1.ID = maxT1.t1ID
WHERE   maxT1.PriceList = 1

I liked Arun's answer better but there is a tiny problem and I could not comment or edit the answer. sparkContext does not have createDeataFrame, sqlContext does (as Thiago mentioned). So:

from pyspark.sql import SQLContext

# assuming the spark environemnt is set and sc is spark.sparkContext 
sqlContext = SQLContext(sc)
schemaPeople = sqlContext.createDataFrame(RDDName)
schemaPeople.createOrReplaceTempView("RDDName")

The command line flags -N or --LINE-NUMBERS causes a line number to be displayed at the beginning of each line in the display.

You can also toggle line numbers without quitting less by typing -N<return>. It it possible to toggle any of less's command line options in this way.

Tested in Chrome 47, 81, and Firefox 76.

If you want to change the value of the currently selected text while you're typing in the same field (for an autocomplete or similar effect), pass document.activeElement as the first parameter.

It's not the most elegant way to do this, but it's pretty simple.

Example usages:

typeInTextarea('hello');
typeInTextarea('haha', document.getElementById('some-id'));

Don't think you're allowed to do that: http://www.w3.org/TR/html5/forms.html#the-placeholder-attribute

The relevant content (emphasis mine):

The placeholder attribute represents a short hint (a word or short phrase) intended to aid the user with data entry when the control has no value. A hint could be a sample value or a brief description of the expected format. The attribute, if specified, must have a value that contains no U+000A LINE FEED (LF) or U+000D CARRIAGE RETURN (CR) characters.

TROUBLESHOOTING STEPS (Doc ID 730066.1)

Connection Timeout errors ORA-3135 and ORA-3136 A connection timeout error can be issued when an attempt to connect to the database does not complete its connection and authentication phases within the time period allowed by the following: SQLNET.INBOUND_CONNECT_TIMEOUT and/or INBOUND_CONNECT_TIMEOUT_ server-side parameters.

Starting with Oracle 10.2, the default for these parameters is 60 seconds where in previous releases it was 0, meaning no timeout.

On a timeout, the client program will receive the ORA-3135 (or possibly TNS-3135) error:

ORA-3135 connection lost contact

and the database will log the ORA-3136 error in its alert.log:

... Sat May 10 02:21:38 2008 WARNING: inbound connection timed out (ORA-3136) ...

• Authentication SQL

When a database session is in the authentication phase, it will issue a sequence of SQL statements. The authentication is not complete until all these are parsed, executed, fetched completely. Some of the SQL statements in this list e.g. on 10.2 are:

select value$ from props$ where name = 'GLOBAL_DB_NAME'

select privilege#,level from sysauth$ connect by grantee#=prior privilege# 
and privilege#>0 start with grantee#=:1 and privilege#>0

select SYS_CONTEXT('USERENV', 'SERVER_HOST'), SYS_CONTEXT('USERENV', 'DB_UNIQUE_NAME'),
SYS_CONTEXT('USERENV', 'INSTANCE_NAME'), SYS_CONTEXT('USERENV', 'SERVICE_NAME'), 
INSTANCE_NUMBER, STARTUP_TIME, SYS_CONTEXT('USERENV', 'DB_DOMAIN') 
from v$instance where INSTANCE_NAME=SYS_CONTEXT('USERENV', 'INSTANCE_NAME')

select privilege# from sysauth$ where (grantee#=:1 or grantee#=1) and privilege#>0

ALTER SESSION SET NLS_LANGUAGE= 'AMERICAN' NLS_TERRITORY= 'AMERICA' NLS_CURRENCY= '$'
NLS_ISO_CURRENCY= 'AMERICA' NLS_NUMERIC_CHARACTERS= '.,' NLS_CALENDAR= 'GREGORIAN'
NLS_DATE_FORMAT= 'DD-MON-RR' NLS_DATE_LANGUAGE= 'AMERICAN' NLS_SORT= 'BINARY' TIME_ZONE= '+02:00'
NLS_COMP= 'BINARY' NLS_DUAL_CURRENCY= '$' NLS_TIME_FORMAT= 'HH.MI.SSXFF AM' NLS_TIMESTAMP_FORMAT=
'DD-MON-RR HH.MI.SSXFF AM' NLS_TIME_TZ_FORMAT= 'HH.MI.SSXFF AM TZR' NLS_TIMESTAMP_TZ_FORMAT=
'DD-MON-RR HH.MI.SSXFF AM TZR'

NOTE: The list of SQL above is not complete and does not represent the ordering of the authentication SQL . Differences may also exist from release to release.

• Hangs during Authentication

The above SQL statements need to be Parsed, Executed and Fetched as happens for all SQL inside an Oracle Database. It follows that any problem encountered during these phases which appears as a hang or severe slow performance may result in a timeout.

Symptoms of such hangs will be seen by the authenticating session as waits for: • cursor: pin S wait on X • latch: row cache objects • row cache lock Other types of wait events are possible; this list may not be complete.

The issue here is that the authenticating session is blocked waiting to get a shared resource which is held by another session inside the database. That blocker session is itself occupied in a long-running activity (or its own hang) which prevents it from releasing the shared resource needed by the authenticating session in a timely fashion. This results in the timeout being eventually reported to the authenticating session.

• Troubleshooting of Authentication hangs

In such situations, we need to find out the blocker process holding the shared resource needed by the authenticating session in order to see what is happening to it.

Typical diagnostics used in such cases are the following:

1. Three consecutive systemstate dumps at level 266 during the time that one or more authenticating sessions are blocked. It is likely that the blocking session will have caused timeouts to more than one connection attempt. Hence, systemstate dumps can be useful even when the time needed to generate them exceeds the period of a single timeout e.g. 60 sec:

      $ sqlplus -prelim '/ as sysdba' 

       oradebug setmypid 
       oradebug unlimit 
       oradebug dump systemstate 266 
       ...wait 90 seconds 
       oradebug dump systemstate 266 
       ...wait 90 seconds 
       oradebug dump systemstate 266 
       quit

• ASH reports covering e.g. 10-15 minutes of a time period during which several timeout errors were seen.
• If possible, Two consecutive queries on V$LATCHHOLDER view for the case where the shared resource being waited for is a latch. select * from v$latchholder; The systemstate dumps should help in identifying the blocker session. Level 266 will show us in what code it is executing which may help in locating any existing bug as the root cause.

Examples of issues which can result in Authentication hangs

• Unpublished Bug 6879763 shared pool simulator bug fixed by patch for unpublished Bug 6966286 see Note 563149.1

• Unpublished Bug 7039896 workaround parameter _enable_shared_pool_durations=false see Note 7039896.8

• Other approaches to avoid the problem

In some cases, it may be possible to avoid problems with Authentication SQL by pinning such statements in the Shared Pool soon after the instance is started and they are freshly loaded. You can use the following artcile to advise on this: Document 726780.1 How to Pin a Cursor in the Shared Pool using DBMS_SHARED_POOL.KEEP

Pinning will prevent them from being flushed out due to inactivity and aging and will therefore prevent them for needing to be reloaded in the future i.e. needing to be reparsed and becoming susceptible to Authentication hang issues.

In python, integers and strings are immutable and are passed by value. You cannot pass a string, or integer, to a function and expect the argument to be modified.

So to convert string limit="100" to a number, you need to do

limit = int(limit) # will return new object (integer) and assign to "limit"

If you really want to go around it, you can use a list. Lists are mutable in python; when you pass a list, you pass it's reference, not copy. So you could do:

def int_in_place(mutable):
    mutable[0] = int(mutable[0])

mutable = ["1000"]
int_in_place(mutable)
# now mutable is a list with a single integer

But you should not need it really. (maybe sometimes when you work with recursions and need to pass some mutable state).

You can use this regular expression (any whitespace or any non-whitespace) as many times as possible down to and including 0.

[\s\S]*

This expression will match as few as possible, but as many as necessary for the rest of the expression.

[\s\S]*?

For example, in this regex [\s\S]*?B will match aB in aBaaaaB. But in this regex [\s\S]*B will match aBaaaaB in aBaaaaB.

Because the designers of CSS didn't have the foresight to imagine the flexibility this would bring. There are plenty of reasons to expand the content area of a box without affecting its relationship to neighbouring elements. If you think it's not possible, put some long nowrap'd text in a box, set a width on the box, and watch how the overflowed content does nothing to the layout.

Yes, this is still relevant with CSS3 in 2019; case in point: flexbox layouts. Flexbox items' margins do not collapse, so in order to space them evenly and align them with the visual edge of the container, one must subtract the items' margins from their container's padding. If any result is < 0, you must use a negative margin on the container, or sum that negative with the existing margin. I.e. the content of the element effects how one defines the margins for it, which is backwards. Summing doesn't work cleanly when flex elements' content have margins defined in different units or are affected by a different font-size, etc.

The example below should, ideally have aligned and evenly spaced grey boxes but, sadly they aren't.

I have encountered enough of these little issues over the years where a little negative padding would have gone a long way, but instead I'm forced to add non-semantic markup, use calc(), or CSS preprocessors which only work when the units are the same, etc.

Here's a pretty ggplot2 solution:

library(ggplot2)
library(scales)  # makes pretty labels on the x-axis

breaks=c(0,1,2,3,4,5,25)

ggplot(mydata,aes(x = V3)) + 
  geom_histogram(breaks = log10(breaks)) + 
  scale_x_log10(
    breaks = breaks,
    labels = scales::trans_format("log10", scales::math_format(10^.x))
  )

Note that to set the breaks in geom_histogram, they had to be transformed to work with scale_x_log10

URL-encoded payload must be provided on the body parameter of the http.NewRequest(method, urlStr string, body io.Reader) method, as a type that implements io.Reader interface.

Based on the sample code:

package main

import (
    "fmt"
    "net/http"
    "net/url"
    "strconv"
    "strings"
)

func main() {
    apiUrl := "https://api.com"
    resource := "/user/"
    data := url.Values{}
    data.Set("name", "foo")
    data.Set("surname", "bar")

    u, _ := url.ParseRequestURI(apiUrl)
    u.Path = resource
    urlStr := u.String() // "https://api.com/user/"

    client := &http.Client{}
    r, _ := http.NewRequest(http.MethodPost, urlStr, strings.NewReader(data.Encode())) // URL-encoded payload
    r.Header.Add("Authorization", "auth_token=\"XXXXXXX\"")
    r.Header.Add("Content-Type", "application/x-www-form-urlencoded")
    r.Header.Add("Content-Length", strconv.Itoa(len(data.Encode())))

    resp, _ := client.Do(r)
    fmt.Println(resp.Status)
}

resp.Status is 200 OK this way.

EDITED: This guy really brought it home and has a good little tutorial http://instantiatorgratification.blogspot.com/2013/05/google-play-services-with-android-studio.html

one side note: I had played around so much that I needed to do a gradlew clean to get it to run succesfully

If you have imported your project or are working from the Sample Maps application located in \extras\google\google_play_services\samples\maps check out this tutorial.

https://stackoverflow.com/a/16598478/2414698

If you are creating a new project from scratch then note Xav's comments on that same post. He describes that Android Studio uses a different compiler and that you have to modify the build.gradle file manually. I did this with success. I copied

• google-play-services.jar
• google-play-services.jar.properties

into my lib directory and added the following to my build.gradle file

dependencies {
    compile files('libs/android-support-v4.jar')
    compile files('libs/google-play-services.jar')
}

Also, if this is a new project check out this post, too.

IMPORTANT - on ubuntu package docker is something entirely different ( avoid it ) :

issue following to view what if any packages you have mentioning docker

dpkg -l|grep docker

if only match is following then you do NOT have docker installed below is an unrelated package

docker - System tray for KDE3/GNOME2 docklet applications

if you see something similar to following then you have docker installed

 dpkg -l|grep docker

ii  docker-ce                                  5:19.03.13~3-0~ubuntu-focal         amd64        Docker: the open-source application container engine

NOTE - ubuntu package docker.io is not getting updates ( obsolete do NOT use )

Instead do this : install the latest version of docker on linux by executing the following:

  sudo curl -sSL https://get.docker.com/ | sh
# sudo curl -sSL https://test.docker.com | sh  # get dev pipeline version
  

here is a typical output ( ubuntu 16.04 )

If you would like to use Docker as a non-root user, you should now consider
adding your user to the "docker" group with something like:

  sudo usermod -aG docker stens

Remember that you will have to log out and back in for this to take effect!

Here is the underlying detailed install instructions which as you can see comes bundled into above technique ... Above one liner gives you same as :

https://docs.docker.com/engine/installation/linux/ubuntulinux/

Once installed you can see what docker packages were installed by issuing

dpkg -l|grep docker
ii  docker-ce                                  5:19.03.13~3-0~ubuntu-focal         amd64        Docker: the open-source application container engine
ii  docker-ce-cli                              5:19.03.13~3-0~ubuntu-focal         amd64        Docker CLI: the open-source application container engine

now Docker updates will get installed going forward when you issue

sudo apt-get update
sudo apt-get upgrade

take a look at

 ls -latr /etc/apt/sources.list.d/*docker*
-rw-r--r-- 1 root root 202 Jun 23 10:01 /etc/apt/sources.list.d/docker.list.save
-rw-r--r-- 1 root root  71 Jul  4 11:32 /etc/apt/sources.list.d/docker.list


cat /etc/apt/sources.list.d/docker.list

deb [arch=amd64] https://apt.dockerproject.org/repo ubuntu-xenial main

or more generally

cd /etc/apt
grep -r docker *

I think who the best mix for html & Css for quick and clean mod is :

        <th class="text-center">Uno</th>
        <th class="text-center">Due</th>

        <th class="text-center">Quattro</th>
    </tr>

        <td>2</td>
        <td>3</td>
        <td>4</td>
    </tr>
</tbody>
</table>

close the <table> init tag then copy where you want :) I hope it can be useful Have a good day w stackoverflow

if I understand you right (not sure), the start parameter /D should help you:

start "cmd" /D %PathName% %comd%

/D sets the start-directory (see start /?)

We tried pretty much what the other answers are describing with moderate level of success. What really worked for us (Apache Kafka 0.8.1) is the class command

sh kafka-run-class.sh kafka.admin.DeleteTopicCommand --topic yourtopic --zookeeper localhost:2181

I'll throw mine in the mix:

https://gist.github.com/btm1/6802312

this evaluates the if statement once and adds no watch listener BUT you can add an additional attribute to the element that has the set-if called wait-for="somedata.prop" and it will wait for that data or property to be set before evaluating the if statement once. that additional attribute can be very handy if you're waiting for data from an XHR request.

angular.module('setIf',[]).directive('setIf',function () {
    return {
      transclude: 'element',
      priority: 1000,
      terminal: true,
      restrict: 'A',
      compile: function (element, attr, linker) {
        return function (scope, iterStartElement, attr) {
          if(attr.waitFor) {
            var wait = scope.$watch(attr.waitFor,function(nv,ov){
              if(nv) {
                build();
                wait();
              }
            });
          } else {
            build();
          }

          function build() {
            iterStartElement[0].doNotMove = true;
            var expression = attr.setIf;
            var value = scope.$eval(expression);
            if (value) {
              linker(scope, function (clone) {
                iterStartElement.after(clone);
                clone.removeAttr('set-if');
                clone.removeAttr('wait-for');
              });
            }
          }
        };
      }
    };
  });

You can use ax.figure.savefig(), as suggested in a comment on the question:

import pandas as pd

df = pd.DataFrame([0, 1])
ax = df.plot.line()
ax.figure.savefig('demo-file.pdf')

This has no practical benefit over ax.get_figure().savefig() as suggested in other answers, so you can pick the option you find the most aesthetically pleasing. In fact, get_figure() simply returns self.figure:

# Source from snippet linked above
def get_figure(self):
    """Return the `.Figure` instance the artist belongs to."""
    return self.figure

Like this ?

<script>
var meta = document.createElement('meta');
meta.setAttribute('http-equiv', 'X-UA-Compatible');
meta.setAttribute('content', 'IE=Edge');
document.getElementsByTagName('head')[0].appendChild(meta);
</script>

My requirements were a bit stricter:

• I had to retain case info (the strings are paths to files displayed to the user, but it's a windows app so internally all operations must be case insensitive)
• I needed keys to be as small as possible (it did make a difference in memory performance, chopped off 110 mb out of 370). This meant that caching lowercase version of keys is not an option.
• I needed creation of the data structures to be as fast as possible (again made a difference in performance, speed this time). I had to go with a builtin

My initial thought was to substitute our clunky Path class for a case insensitive unicode subclass - but:

• proved hard to get that right - see: A case insensitive string class in python
• turns out that explicit dict keys handling makes code verbose and messy - and error prone (structures are passed hither and thither, and it is not clear if they have CIStr instances as keys/elements, easy to forget plus some_dict[CIstr(path)] is ugly)

So I had finally to write down that case insensitive dict. Thanks to code by @AaronHall that was made 10 times easier.

                                 super(LowerDict, self).__repr__())

Implicit vs explicit is still a problem, but once dust settles, renaming of attributes/variables to start with ci (and a big fat doc comment explaining that ci stands for case insensitive) I think is a perfect solution - as readers of the code must be fully aware that we are dealing with case insensitive underlying data structures. This will hopefully fix some hard to reproduce bugs, which I suspect boil down to case sensitivity.

Comments/corrections welcome :)

I had this problem and it turned out I didn't have any padding on the ul, which was stopping the discs from being visible.

I was able to solve this entirely in IB:

1. Make constraints to align the center Y of each of your subviews to the bottom edge of the superview.
2. Set the multiplier of each of these constraints to 1/2n, 3/2n, 5/2n, …, n-1/2n where n is the number of subviews you are distributing.

So if you have three labels, set the multipliers to each of those constraints to 0.1666667, 0.5, 0.833333.

I found that the file.framework was referencing a file outside my project. So I dragged the file into my frameworks folder under my project and then got rid of the earlier file.framework file and it worked.

No, break is the correct solution.

Adding a boolean variable makes the code harder to read and adds a potential source of errors.

CREATE TRIGGER [dbo].[after_update] ON [dbo].[MYTABLE]
AFTER UPDATE
AS
BEGIN
    DECLARE @ID INT

    SELECT @ID = D.ID
    FROM inserted D

    UPDATE MYTABLE
    SET mytable.CHANGED_ON = GETDATE()
        ,CHANGED_BY = USER_NAME(USER_ID())
    WHERE ID = @ID
END

You can also replace complicated condition with single method call to make it less evil in maintain.

This might be seen as a little complex but does exactly what you want

SELECT 
  DISTINCT(p.`ProductID`) AS ProductID,
  SUM(pl.CashAmount) AS Cash,
  SUM(pr.CashAmount) AS `Check`,
  SUM(px.CashAmount) AS `Credit Card`,
  SUM(pl.CashAmount) + SUM(pr.CashAmount) +SUM(px.CashAmount) AS Amount
FROM
  `payments` AS p 
  LEFT JOIN (SELECT ProductID,PaymentMethod , IFNULL(Amount,0) AS CashAmount FROM payments WHERE PaymentMethod = 'Cash' GROUP BY ProductID , PaymentMethod ) AS pl 
    ON pl.`PaymentMethod` = p.`PaymentMethod` AND pl.ProductID = p.`ProductID`
  LEFT JOIN (SELECT ProductID,PaymentMethod , IFNULL(Amount,0) AS CashAmount FROM payments WHERE PaymentMethod = 'Check' GROUP BY ProductID , PaymentMethod) AS pr 
    ON pr.`PaymentMethod` = p.`PaymentMethod` AND pr.ProductID = p.`ProductID`
  LEFT JOIN (SELECT ProductID, PaymentMethod , IFNULL(Amount,0) AS CashAmount FROM payments WHERE PaymentMethod = 'Credit Card' GROUP BY ProductID , PaymentMethod) AS px 
    ON px.`PaymentMethod` = p.`PaymentMethod` AND px.ProductID = p.`ProductID`
GROUP BY p.`ProductID` ;

Output

ProductID | Cash | Check | Credit Card | Amount
-----------------------------------------------
    3     | 20   |  15   |   25        |  60
    4     | 5    |  6    |   7         |  18

SQL Fiddle Demo

if you want to call click event:

SomeButton.RaiseEvent(new RoutedEventArgs(Button.ClickEvent));

And if you want the button looks like it is pressed:

typeof(Button).GetMethod("set_IsPressed", BindingFlags.Instance | BindingFlags.NonPublic).Invoke(SomeButton, new object[] { true });

and unpressed after that:

typeof(Button).GetMethod("set_IsPressed", BindingFlags.Instance | BindingFlags.NonPublic).Invoke(SomeButton, new object[] { false });

or use the ToggleButton

Assuming, that you have root access on the box you can do:

sudo -u postgres psql

If that fails with a database "postgres" does not exists this block.

sudo -u postgres psql template1

Then sudo nano /etc/postgresql/11/main/pg_hba.conf file

local   all         postgres                          ident

For newer versions of PostgreSQL ident actually might be peer.

Inside the psql shell you can give the DB user postgres a password:

ALTER USER postgres PASSWORD 'newPassword';

Simply create a .bat file with the following lines in it:

@ECHO OFF
set CLASSPATH=.
set CLASSPATH=%CLASSPATH%;path/to/needed/jars/my.jar

%JAVA_HOME%\bin\java -Xms128m -Xmx384m -Xnoclassgc ro.my.class.MyClass

The easiest way is to redirect the output of the echo by >>:

echo 'VNCSERVERS="1:root"' >> /etc/sysconfig/configfile
echo 'VNCSERVERARGS[1]="-geometry 1600x1200"' >> /etc/sysconfig/configfile

This also happens when you copy a web page from one solution to another, then you run your solution and find out that it has a different connection string name in the webconfig. Then you carelessly change the name of the connection string in the properties panel in the design view of the page.

Better to just change it in the code portion instead of the design.

The provided Answers did not solve my problem,

It did not:

1. Remove parent domain cookies (from a.b.c; remove b.c; cookies),
2. Remove cookies from a higher path other then root.

My script does, see.

<?php function unset_cookie($name)
{
    $host = $_SERVER['HTTP_HOST'];
    $domain = explode(':', $host)[0];

    $uri = $_SERVER['REQUEST_URI'];
    $uri = rtrim(explode('?', $uri)[0], '/');

    if ($uri && !filter_var('file://' . $uri, FILTER_VALIDATE_URL)) {
        throw new Exception('invalid uri: ' . $uri);
    }

    $parts = explode('/', $uri);

    $cookiePath = '';
    foreach ($parts as $part) {
        $cookiePath = '/'.ltrim($cookiePath.'/'.$part, '//');

        setcookie($name, '', 1, $cookiePath);

        $_domain = $domain;
        do {
            setcookie($name, '', 1, $cookiePath, $_domain);
        } while (strpos($_domain, '.') !== false && $_domain = substr($_domain, 1 + strpos($_domain, '.')));
    }
}

It is not the most pretty/safe/optimal solution, so use this only if you do not known the cookie-path and/or cookie-domain's. Or use the idea in order to create your version.

document.FormName.btnSubmit.click(); 

works for me. Enjoy.

Just disable the form field:

document.getElementById('input').disabled

You could do $stmt->queryString to obtain the SQL query used in the statement. If you want to save the entire $stmt variable (I can't see why), you could just copy it. It is an instance of PDOStatement so there is apparently no advantage in storing it.

When you are editing a table
Right Click -> Check Constraints -> Add -> Type something like Frequency IN ('Daily', 'Weekly', 'Monthly', 'Yearly') in expression field and a good constraint name in (Name) field.
You are done.

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

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

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

Using the below approach deep clones object

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

If the class uses as a parameterized type, it can declare an array of type T[], but it cannot directly instantiate such an array. Instead, a common approach is to instantiate an array of type Object[], and then make a narrowing cast to type T[], as shown in the following:

  public class Portfolio<T> {
  T[] data;
 public Portfolio(int capacity) {
   data = new T[capacity];                 // illegal; compiler error
   data = (T[]) new Object[capacity];      // legal, but compiler warning
 }
 public T get(int index) { return data[index]; }
 public void set(int index, T element) { data[index] = element; }
}

Use zip(*list):

>>> l = [(1,2), (3,4), (8,9)]
>>> list(zip(*l))
[(1, 3, 8), (2, 4, 9)]

The zip() function pairs up the elements from all inputs, starting with the first values, then the second, etc. By using *l you apply all tuples in l as separate arguments to the zip() function, so zip() pairs up 1 with 3 with 8 first, then 2 with 4 and 9. Those happen to correspond nicely with the columns, or the transposition of l.

zip() produces tuples; if you must have mutable list objects, just map() the tuples to lists or use a list comprehension to produce a list of lists:

map(list, zip(*l))          # keep it a generator
[list(t) for t in zip(*l)]  # consume the zip generator into a list of lists

Why don't you let PHP do the job?

"UPDATE member_profile SET points= ' ". ($points+1) ." '  WHERE user_id = '".$userid."'"

You should be able to match it with: /<primaryAddress>(.+?)<\/primaryAddress>/

The content between the tags will be in the matched group.

If you want to FIXED the size of your RecyclerView item in all devices. You can do like this

public class GridSpacingItemDecoration extends RecyclerView.ItemDecoration {

    private int mSpanCount;
    private float mItemSize;

    public GridSpacingItemDecoration(int spanCount, int itemSize) {
        this.mSpanCount = spanCount;
        mItemSize = itemSize;
    }

    @Override
    public void getItemOffsets(final Rect outRect, final View view, RecyclerView parent,
            RecyclerView.State state) {
        final int position = parent.getChildLayoutPosition(view);
        final int column = position % mSpanCount;
        final int parentWidth = parent.getWidth();
        int spacing = (int) (parentWidth - (mItemSize * mSpanCount)) / (mSpanCount + 1);
        outRect.left = spacing - column * spacing / mSpanCount;
        outRect.right = (column + 1) * spacing / mSpanCount;

        if (position < mSpanCount) {
            outRect.top = spacing;
        }
        outRect.bottom = spacing;
    }
}

recyclerview_item.xml

<LinearLayout
    xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="@dimen/recycler_view_item_width" 
    ...
    >
    ...
</LinearLayout>

dimens.xml

 <dimen name="recycler_view_item_width">60dp</dimen>

Activity

int numberOfColumns = 3;
mRecyclerView.setLayoutManager(new GridLayoutManager(this, numberOfColumns));
mRecyclerView.setAdapter(...);
mRecyclerView.addItemDecoration(new GridSpacingItemDecoration(3,
        getResources().getDimensionPixelSize(R.dimen.recycler_view_item_width)));

In Oracle the solution would be:

UPDATE
    MasterTbl
SET
    (TotalX,TotalY,TotalZ) =
      (SELECT SUM(X),SUM(Y),SUM(Z)
         from DetailTbl where DetailTbl.MasterID = MasterTbl.ID)

Don't know if your system allows the same.

ALTER TABLE MyTable MODIFY Col3 varchar(20) NULL;

My contribution in ES6 terms. In general it finds the intersection of an array with indefinite number of arrays provided as arguments.

}_x000D_
var arrs = [[0,2,4,6,8],[4,5,6,7],[4,6]],_x000D_
     arr = [0,1,2,3,4,5,6,7,8,9];_x000D_
_x000D_
document.write("<pre>" + JSON.stringify(arr.intersect(...arrs)) + "</pre>");

Note: This answer is a pure Gradle answer, I use this in IntelliJ on a regular basis but I don't know how the integration is with Android Studio. I am a believer in knowing what is going on for me, so this is how I use Gradle and Android.

TL;DR Full Example - https://github.com/ethankhall/driving-time-tracker/

Disclaimer: This is a project I am/was working on.

Gradle has a defined structure ( that you can change, link at the bottom tells you how ) that is very similar to Maven if you have ever used it.

Project Root
+-- src
|   +-- main (your project)
|   |   +-- java (where your java code goes)
|   |   +-- res  (where your res go)
|   |   +-- assets (where your assets go)
|   |   \-- AndroidManifest.xml
|   \-- instrumentTest (test project)
|       \-- java (where your java code goes)
+-- build.gradle
\-- settings.gradle

If you only have the one project, the settings.gradle file isn't needed. However you want to add more projects, so we need it.

Now let's take a peek at that build.gradle file. You are going to need this in it (to add the android tools)

build.gradle

buildscript {
    repositories {
        mavenCentral()
    }
    dependencies {
        classpath 'com.android.tools.build:gradle:0.3'
    }
}

Now we need to tell Gradle about some of the Android parts. It's pretty simple. A basic one (that works in most of my cases) looks like the following. I have a comment in this block, it will allow me to specify the version name and code when generating the APK.

build.gradle

apply plugin: "android"
android {
        compileSdkVersion 17
        /*
        defaultConfig {
            versionCode = 1
            versionName = "0.0.0"
        }
        */
    }

Something we are going to want to add, to help out anyone that hasn't seen the light of Gradle yet, a way for them to use the project without installing it.

build.gradle

task wrapper(type: org.gradle.api.tasks.wrapper.Wrapper) {
    gradleVersion = '1.4'
}

So now we have one project to build. Now we are going to add the others. I put them in a directory, maybe call it deps, or subProjects. It doesn't really matter, but you will need to know where you put it. To tell Gradle where the projects are you are going to need to add them to the settings.gradle.

Directory Structure:

Project Root
+-- src (see above)
+-- subProjects (where projects are held)
|   +-- reallyCoolProject1 (your first included project)
|       \-- See project structure for a normal app
|   \-- reallyCoolProject2 (your second included project)
|       \-- See project structure for a normal app
+-- build.gradle
\-- settings.gradle

settings.gradle:

include ':subProjects:reallyCoolProject1'
include ':subProjects:reallyCoolProject2'

The last thing you should make sure of is the subProjects/reallyCoolProject1/build.gradle has apply plugin: "android-library" instead of apply plugin: "android".

Like every Gradle project (and Maven) we now need to tell the root project about it's dependency. This can also include any normal Java dependencies that you want.

build.gradle

dependencies{
    compile 'com.fasterxml.jackson.core:jackson-core:2.1.4'
    compile 'com.fasterxml.jackson.core:jackson-databind:2.1.4'
    compile project(":subProjects:reallyCoolProject1")
    compile project(':subProjects:reallyCoolProject2')
}

I know this seems like a lot of steps, but they are pretty easy once you do it once or twice. This way will also allow you to build on a CI server assuming you have the Android SDK installed there.

NDK Side Note: If you are going to use the NDK you are going to need something like below. Example build.gradle file can be found here: https://gist.github.com/khernyo/4226923

build.gradle

task copyNativeLibs(type: Copy) {
    from fileTree(dir: 'libs', include: '**/*.so' )  into  'build/native-libs'
}
tasks.withType(Compile) { compileTask -> compileTask.dependsOn copyNativeLibs }

clean.dependsOn 'cleanCopyNativeLibs'

tasks.withType(com.android.build.gradle.tasks.PackageApplication) { pkgTask ->
  pkgTask.jniDir new File('build/native-libs')
}

Alternate solution to doing shallow clone (git clone --depth=1 <URL>) would be, if remote side supports it, to use --remote option of git archive:

$ git archive --format=tar --remote=<repository URL> HEAD | tar xf -

Or, if remote repository in question is browse-able using some web interface like gitweb or GitHub, then there is a chance that it has 'snapshot' feature, and you can download latest version (without versioning information) from web interface.

import math

def is_square(n):
    sqrt = math.sqrt(n)
    return (sqrt - int(sqrt)) == 0

A perfect square is a number that can be expressed as the product of two equal integers. math.sqrt(number) return a float. int(math.sqrt(number)) casts the outcome to int.

If the square root is an integer, like 3, for example, then math.sqrt(number) - int(math.sqrt(number)) will be 0, and the if statement will be False. If the square root was a real number like 3.2, then it will be True and print "it's not a perfect square".

It fails for a large non-square such as 152415789666209426002111556165263283035677490.

Add pointer-events: none; to the overlay.

Original answer: My suggestion would be that you could capture the click event with the overlay, hide the overlay, then refire the click event, then display the overlay again. I'm not sure if you'd get a flicker effect though.

[Update] Exactly this problem and exactly my solution just appeared in this post: "Forwarding Mouse Events Through Layers". I know its probably a little late for the OP, but for the sake of somebody having this problem in the future, I though I would include it.

Set data to this:

data ={"eventType":"AAS_PORTAL_START","data":{"uid":"hfe3hf45huf33545","aid":"1","vid":"1"}}

I have struggled with this as well. In fact I got here with a google search of exactly the same question. Reading all these answers finally painted a picture in my head and I decided to try to get this down looking at the state of the 2 repositories and 1 sandbox and actions performed over time while watching the version of them. So here is what I came up with. Please correct me if I messed up anywhere.

The three repos with a fetch:

---------------------     -----------------------     -----------------------
- Remote Repo       -     - Remote Repo         -     - Remote Repo         -

---------------------     -----------------------     -----------------------

This helped me understand why a fetch is pretty important.

Try this:

tar -czf my.tar.gz dir/

But are you sure you are not compressing some .exe file or something? Maybe the problem is not with te compression, but with the files you are compressing?

While xrange is faster than range in most circumstances, the difference in performance is pretty minimal. The little program below compares iterating over a range and an xrange:

import timeit
# Try various list sizes.
for list_len in [1, 10, 100, 1000, 10000, 100000, 1000000]:
  # Time doing a range and an xrange.
  rtime = timeit.timeit('a=0;\nfor n in range(%d): a += n'%list_len, number=1000)
  xrtime = timeit.timeit('a=0;\nfor n in xrange(%d): a += n'%list_len, number=1000)
  # Print the result
  print "Loop list of len %d: range=%.4f, xrange=%.4f"%(list_len, rtime, xrtime)

The results below shows that xrange is indeed faster, but not enough to sweat over.

Loop list of len 1: range=0.0003, xrange=0.0003
Loop list of len 10: range=0.0013, xrange=0.0011
Loop list of len 100: range=0.0068, xrange=0.0034
Loop list of len 1000: range=0.0609, xrange=0.0438
Loop list of len 10000: range=0.5527, xrange=0.5266
Loop list of len 100000: range=10.1666, xrange=7.8481
Loop list of len 1000000: range=168.3425, xrange=155.8719

So by all means use xrange, but unless you're on a constrained hardware, don't worry too much about it.

Sometimes there is some error in the local Maven repo. So please close your eclipse and delete the jar spring-webmvc from your local .m2 then open Eclipse and on the project press Update Maven Dependencies.

Then Eclipse will download the dependency again for you. That how I fixed the same problem.

Most of the answers above should suffice you but if you are doing a lot more of such predicate and complex combinations check out Squeel. You will be able to doing something like:

Topic.where{{forum_id.not_in => @forums.map(&:id)}}
Topic.where{forum_id.not_in @forums.map(&:id)} 
Topic.where{forum_id << @forums.map(&:id)}

For an updated answer see this SO question:

calling web service using VBA code in excel 2010

Both threads should be merged though.

I had same problem. I just solved it with declaring adapter public before onCreate of class.

PostAdapter postAdapter;

after that

postAdapter = new PostAdapter(getActivity(), posts);
recList.setAdapter(postAdapter);

at last I have called:

@Override
protected void onPostExecute(Void aVoid) {
    super.onPostExecute(aVoid);
    // Display the size of your ArrayList
    Log.i("TAG", "Size : " + posts.size());
    progressBar.setVisibility(View.GONE);
    postAdapter.notifyDataSetChanged();
}

May this will helps you.

Here is a picture that shows the difference between add() and replace()

So add() method keeps on adding fragments on top of the previous fragment in FragmentContainer.

While replace() methods clears all the previous Fragment from Containers and then add it in FragmentContainer.

What is addToBackStack

addtoBackStack method can be used with add() and replace methods. It serves a different purpose in Fragment API.

What is the purpose?

Fragment API unlike Activity API does not come with Back Button navigation by default. If you want to go back to the previous Fragment then the we use addToBackStack() method in Fragment. Let's understand both

Case 1:

getSupportFragmentManager()
            .beginTransaction()
            .add(R.id.fragmentContainer, fragment, "TAG")
            .addToBackStack("TAG")
            .commit();

Case 2:

getSupportFragmentManager()
            .beginTransaction()
            .add(R.id.fragmentContainer, fragment, "TAG")
            .commit();

The code:

public class Test {
    public static void main(String args[]) {
        String string = args[0];
        System.out.println("last character: " +
                           string.substring(string.length() - 1)); 
    }
}

The output of java Test abcdef:

As per official documentation link shared by Andre Kirpitch, Oracle 10g gives a maximum size of 4000 bytes or characters for varchar2. If you are using a higher version of oracle (for example Oracle 12c), you can get a maximum size upto 32767 bytes or characters for varchar2. To utilize the extended datatype feature of oracle 12, you need to start oracle in upgrade mode. Follow the below steps in command prompt:

1) Login as sysdba (sqlplus / as sysdba)

2) SHUTDOWN IMMEDIATE;

3) STARTUP UPGRADE;

4) ALTER SYSTEM SET max_string_size=extended;

5) Oracle\product\12.1.0.2\rdbms\admin\utl32k.sql

6) SHUTDOWN IMMEDIATE;

7) STARTUP;

To make sure you're always on the safe side, without getting all kinds of unwanted code insertion use FILTERS:

echo filter_input(INPUT_GET,"link",FILTER_SANITIZE_STRING);

Using dt.weekday_name is deprecated since pandas 0.23.0, instead, use dt.day_name():

df = pd.DataFrame({'my_dates':['2015-01-01','2015-01-02','2015-01-03'],'myvals':[1,2,3]})
df['my_dates'] = pd.to_datetime(df['my_dates'])

df['my_dates'].dt.day_name()

0    Thursday
1      Friday
2    Saturday
Name: my_dates, dtype: object

It's all you need to remember for 99% of cases.

Blowfish is not a hashing algorithm. It's an encryption algorithm. What that means is that you can encrypt something using blowfish, and then later on you can decrypt it back to plain text.

SHA512 is a hashing algorithm. That means that (in theory) once you hash the input you can't get the original input back again.

They're 2 different things, designed to be used for different tasks. There is no 'correct' answer to "is blowfish better than SHA512?" You might as well ask "are apples better than kangaroos?"

If you want to read some more on the topic here's some links:

try this:

var maxid = from i in items
            group i by i.clientid int g
            select new { id = g.Max(i=>i.ID }

Here are a few ways to do it

INSERT INTO pxlot (realname,email,address,phone,status,regtime,ip) 
select '$realname','$email','$address','$phone','0','$dateTime','$ip' 
from SOMETABLEWITHTONSOFROWS LIMIT 3;

or

INSERT INTO pxlot (realname,email,address,phone,status,regtime,ip) 
select '$realname','$email','$address','$phone','0','$dateTime','$ip'
union all select '$realname','$email','$address','$phone','0','$dateTime','$ip'
union all select '$realname','$email','$address','$phone','0','$dateTime','$ip'

or

INSERT INTO pxlot (realname,email,address,phone,status,regtime,ip) 
values ('$realname','$email','$address','$phone','0','$dateTime','$ip')
,('$realname','$email','$address','$phone','0','$dateTime','$ip')
,('$realname','$email','$address','$phone','0','$dateTime','$ip')

Start with the use of tabs - the \t character modifier. It will advance to a fixed location (columns, terminal lingo).

However, it doesn't help if there are differences of more than the column width (4 characters, if I recall correctly).

To fix that, write your "OK/NOK" stuff using a fixed number of tabs (5? 6?, try it). Then return (\r) without new-lining, and write your message.

To my surprise, the "preventDefault()" method is working for me on latest Google Chrome (version 85) on iOS 13.7. It also works on Safari on the same device and also working on my Android 8.0 tablet. I am currently implemented it for 2D view on my site here: https://papercraft-maker.com

s.index(x[, i[, j]])

index of the first occurrence of x in s (at or after index i and before index j)

Format with Currency format string

=Format(Fields!Price.Value, "C")

It will give you 2 decimal places with "$" prefixed.

You can find other format strings on MSDN: Adding Style and Formatting to a ReportViewer Report

Note: The MSDN article has been archived to the "VS2005_General" document, which is no longer directly accessible online. Here is the excerpt of the formatting strings referenced:

Formatting Numbers

The following table lists common .NET Framework number formatting strings.

Format string, Name

C or c Currency

D or d Decimal

E or e Scientific

F or f Fixed-point

G or g General

N or n Number

P or p Percentage

R or r Round-trip

X or x Hexadecimal

You can modify many of the format strings to include a precision specifier that defines the number of digits to the right of the

decimal point. For example, a formatting string of D0 formats the number so that it has no digits after the decimal point. You

can also use custom formatting strings, for example, #,###.

Formatting Dates

The following table lists common .NET Framework date formatting strings.

Format string, Name

d Short date

D Long date

t Short time

T Long time

f Full date/time (short time)

F Full date/time (long time)

g General date/time (short time)

G General date/time (long time)

M or m Month day

R or r RFC1123 pattern

Y or y Year month

You can also a use custom formatting strings; for example, dd/MM/yy. For more information about .NET Framework formatting strings, see Formatting Types.

Here is a quick implementation with samples:

Checkbox to check all items:

<input id="btnSelectAll" type="checkbox">

Single item (for table row):

<input class="single-item" name="item[]" type="checkbox">

Js code for jQuery:

$(document).on('click', '#btnSelectAll', function(state) {
    if ($('#btnSelectAll').is(':checked')) {
        $('.single-item').prop('checked', true);
        $('.batch-erase').addClass('d-block');
    } else {
        $('.single-item').prop('checked', false);
        $('.batch-erase').removeClass('d-block');
    }
});

Batch delete item:

<div class="batch-erase d-none">
    <a href="/path/to/delete" class="btn btn-danger btn-sm">
        <i class="fe-trash"></i> Delete All
    </a>
</div>

Basically it contains all the attributes which describe the object in question. It can be used to alter or read the attributes. Quoting from the documentation for __dict__

A dictionary or other mapping object used to store an object's (writable) attributes.

Remember, everything is an object in Python. When I say everything, I mean everything like functions, classes, objects etc (Ya you read it right, classes. Classes are also objects). For example:

def func():
    pass

func.temp = 1

print(func.__dict__)

class TempClass:
    a = 1
    def temp_function(self):
        pass

print(TempClass.__dict__)

will output

{'temp': 1}
{'__module__': '__main__', 
 'a': 1, 
 'temp_function': <function TempClass.temp_function at 0x10a3a2950>, 
 '__dict__': <attribute '__dict__' of 'TempClass' objects>, 
 '__weakref__': <attribute '__weakref__' of 'TempClass' objects>, 
 '__doc__': None}

Link to the PyYAML documentation showing the difference for the default_flow_style parameter. To write it to a file in block mode (often more readable):

d = {'A':'a', 'B':{'C':'c', 'D':'d', 'E':'e'}}
with open('result.yml', 'w') as yaml_file:
    yaml.dump(d, yaml_file, default_flow_style=False)

produces:

A: a
B:
  C: c
  D: d
  E: e

Here is a Github link to a lightweight and very easy to integrate library that enables you to play with borders as you want for any widget you want, simply based on a FrameLayout widget.

Here is a quick sample code for you to see how easy it is, but you will find more information on the link.

<com.khandelwal.library.view.BorderFrameLayout
            android:layout_width="match_parent"
            android:layout_height="match_parent"
            app:leftBorderColor="#00F0F0"
            app:leftBorderWidth="10dp"
            app:topBorderColor="#F0F000"
            app:topBorderWidth="15dp"
            app:rightBorderColor="#F000F0"
            app:rightBorderWidth="20dp"
            app:bottomBorderColor="#000000"
            app:bottomBorderWidth="25dp" >
    </com.khandelwal.library.view.BorderFrameLayout>

So, if you don't want borders on bottom, delete the two lines about bottom in this custom widget, and that's done.

And no, I'm neither the author of this library nor one of his friend ;-)

When using Google Fonts, your workflow is divided in 3 steps : "Select", "Customize", "Embed". If you look closely, at the right end of the "Use" page, there is a little arrow which allows you to download the font currently in your collection.

After that, and once the font is installed on your system, you just have to use it like any other regular font using the font-family CSS directive.

You will have to set environmental variables properly for each compiler. There are commands on your Program menu for each compiler that does that, while opening a command prompt.

Another option is of course to use the IDE for building your application.

In "classic" C language (C89/90) when you call an undeclared function, C assumes that it returns an int and also attempts to derive the types of its parameters from the types of the actual arguments (no, it doesn't assume that it has no parameters, as someone suggested before).

In your specific example the compiler would look at do_something(dest, src) call and implicitly derive a declaration for do_something. The latter would look as follows

int do_something(char *, char *)

However, later in the code you explicitly declare do_something as

char *do_something(char *, const char *)

As you can see, these declarations are different from each other. This is what the compiler doesn't like.

Copy the file into your src folder. Go to the Project Explorer in Eclipse, Right-click on your project, and click on "Refresh". The file should appear on the Project Explorer pane as well.

Simple example: Form with textbox and Search button.

If you write "name" into the textbox and submit form, it will brings you patients with "name" in table.

View:

@using (Ajax.BeginForm("GetPatients", "Patient", new AjaxOptions {//GetPatients is name of method in PatientController
    InsertionMode = InsertionMode.Replace, //target element(#patientList) will be replaced
    UpdateTargetId = "patientList",
    LoadingElementId = "loader" // div with .gif loader - that is shown when data are loading   
}))
{
    string patient_Name = "";
    @Html.EditorFor(x=>patient_Name) //text box with name and id, that it will pass to controller
    <input  type="submit" value="Search" />
}

@* ... *@
<div id="loader" class=" aletr" style="display:none">
    Loading...<img src="~/Images/ajax-loader.gif" />
</div>
@Html.Partial("_patientList") @* this is view with patient table. Same view you will return from controller *@

_patientList.cshtml:

@model IEnumerable<YourApp.Models.Patient>

<table id="patientList" >
<tr>
    <th>
        @Html.DisplayNameFor(model => model.Name)
    </th>
    <th>
        @Html.DisplayNameFor(model => model.Number)
    </th>       
</tr>
@foreach (var patient in Model) {
<tr>
    <td>
        @Html.DisplayFor(modelItem => patient.Name)
    </td>
    <td>
        @Html.DisplayFor(modelItem => patient.Number)
    </td>
</tr>
}
</table>

Patient.cs

public class Patient
{
   public string Name { get; set; }
   public int Number{ get; set; }
}

PatientController.cs

public PartialViewResult GetPatients(string patient_Name="")
{
   var patients = yourDBcontext.Patients.Where(x=>x.Name.Contains(patient_Name))
   return PartialView("_patientList", patients);
}

And also as TSmith said in comments, don´t forget to install jQuery Unobtrusive Ajax library through NuGet.

Your best bet would be using the RFC defined mime-type audio/mpeg.

It is really bad idea, but...

for x in range(0, 9):
    globals()['string%s' % x] = 'Hello'

and then for example:

print(string3)

will give you:

Hello

However this is bad practice. You should use dictionaries or lists instead, as others propose. Unless, of course, you really wanted to know how to do it, but did not want to use it.

fastest one:

$("div#selected ul li").length

this is the best way that i have found:

Something like:

File file = new File("C:\\user\\Desktop\\dir1\\dir2\\filename.txt");
file.getParentFile().mkdirs();
FileWriter writer = new FileWriter(file);

Why dont you take the string and split it

Example on the url

var url = "http://www.youtube.com/watch?p=DB852818BF378DAC&v=1q-k-uN73Gk"

you can do a split as

var params = url.split("?")[1].split("&");

You will get array of strings with params as name value pairs with "=" as the delimiter.

It is the same as in eclipse:

• Select text for upper case and Ctrl + Shift + X
• Select text for lower case and Ctrl + Shift + Y

I'd suggest that you create a setenv script whose sole purpose is to provide locations for various components across your system.

All other scripts would then source this script so that all locations are common across all scripts using the setenv script.

This is very useful when running cronjobs. You get a minimal environment when running cron, but if you make all cron scripts first include the setenv script then you are able to control and synchronise the environment that you want the cronjobs to execute in.

We used such a technique on our build monkey that was used for continuous integration across a project of about 2,000 kSLOC.

Here's where it gets confusing, the text states "If the balance factor of R is 1, it means the insertion occurred on the (external) right side of that node and a left rotation is needed". But from m understanding the text said (as I quoted) that if the balance factor was within [-1, 1] then there was no need for balancing?

Okay, epiphany time.

Consider what a rotation does. Let's think about a left rotation.

 P = parent
 O = ourself (the element we're rotating)
 RC = right child
 LC = left child (of the right child, not of ourself)

 P              10
  \               \
   O               15
    \                \
     RC               20
    /                /
   LC               18

          ?
 P              10
   \               \
     RC              20
   /               /
  O              15
   \               \
   LC              18

 basically, what happens is;

 1. our right child moves into our position
 2. we become the left child of our right child
 3. our right child's left child becomes our right

Now, the big thing you have to notice here - this left rotation HAS NOT CHANGED THE DEPTH OF THE TREE. We're no more balanced for having done it.

But - and here's the magic in AVL - if we rotated the right child to the right FIRST, what we'd have is this...

 P
  \
   O
    \
     LC
      \
       RC

And NOW if we rotate O left, what we get is this...

 P
   \
     LC
    /  \
   O   RC

Magic! we've managed to get rid of a level of the tree - we've made the tree balanced.

Balancing the tree means getting rid of excess depth, and packing the upper levels more completely - which is exactly what we've just done.

That whole stuff about single/double rotations is simply that you have to have your subtree looking like this;

 P
  \
   O
    \
     LC
      \
       RC

before you rotate - and you may have to do a right rotate to get into that state. But if you're already in that state, you only need to do the left rotate.

Swift 3.0

To convert image to base64 string

Tested in playground

    var logo = UIImage(named: "image_logo")
    let imageData:Data =  UIImagePNGRepresentation(logo)
    let base64String = imageData.base64EncodedString()
    print(base64String)

Simply call list on the generator.

lst = list(gen)
lst

Be aware that this affects the generator which will not return any further items.

You also cannot directly call list in IPython, as it conflicts with a command for listing lines of code.

Tested on this file:

def gen():
    yield 1
    yield 2
    yield 3
    yield 4
    yield 5
import ipdb
ipdb.set_trace()

g1 = gen()

text = "aha" + "bebe"

mylst = range(10, 20)

which when run:

$ python code.py 
> /home/javl/sandbox/so/debug/code.py(10)<module>()
      9 
---> 10 g1 = gen()
     11 

ipdb> n
> /home/javl/sandbox/so/debug/code.py(12)<module>()
     11 
---> 12 text = "aha" + "bebe"
     13 

ipdb> lst = list(g1)
ipdb> lst
[1, 2, 3, 4, 5]
ipdb> q
Exiting Debugger.

General method for escaping function/variable/debugger name conflicts

There are debugger commands p and pp that will print and prettyprint any expression following them.

So you could use it as follows:

$ python code.py 
> /home/javl/sandbox/so/debug/code.py(10)<module>()
      9 
---> 10 g1 = gen()
     11 

ipdb> n
> /home/javl/sandbox/so/debug/code.py(12)<module>()
     11 
---> 12 text = "aha" + "bebe"
     13 

ipdb> p list(g1)
[1, 2, 3, 4, 5]
ipdb> c

There is also an exec command, called by prefixing your expression with !, which forces debugger to take your expression as Python one.

ipdb> !list(g1)
[]

For more details see help p, help pp and help exec when in debugger.

ipdb> help exec
(!) statement
Execute the (one-line) statement in the context of
the current stack frame.
The exclamation point can be omitted unless the first word
of the statement resembles a debugger command.
To assign to a global variable you must always prefix the
command with a 'global' command, e.g.:
(Pdb) global list_options; list_options = ['-l']

Just to make a more comprehensive answer, the C way of iterating over a string can apply in Python, if you really wanna force a square peg into a round hole.

i = 0
while i < len(str):
    print str[i]
    i += 1

But then again, why do that when strings are inherently iterable?

for i in str:
    print i

CLARIFICATION

When this question was asked the OP did not say that he wanted the number of LOGICAL cores rather than the actual number of cores, so this answer logically (no pun intended) answers with a way to get the actual number of real physical cores, not the number that the OS tries to virtualize through hyperthreading voodoo.

UPDATE TO HANDLE FLAW IN YOSEMITE

Due to a weird bug in OS X Yosemite (and possibly newer versions, such as the upcoming El Capitan), I've made a small modification. (The old version still worked perfectly well if you just ignore STDERR, which is all the modification does for you.)

Every other answer given here either

1. gives incorrect information
2. gives no information, due to an error in the command implementation
3. runs unbelievably slowly (taking the better part of a minute to complete), or
4. gives too much data, and thus might be useful for interactive use, but is useless if you want to use the data programmatically (for instance, as input to a command like bundle install --jobs 3 where you want the number in place of 3 to be one less than the number of cores you've got, or at least not more than the number of cores)

The way to get just the number of cores, reliably, correctly, reasonably quickly, and without extra information or even extra characters around the answer, is this:

system_profiler SPHardwareDataType 2> /dev/null | grep 'Total Number of Cores' | cut -d: -f2 | tr -d ' '

Below is the code that implements custom vertical scrollbar. The important detail here is to know when scrollbar is needed by calculating how much space is consumed by the controls that you add to the panel.

If protocol HTTP is given as State full protocol,browser window uses single connection to communicate with web server for multiple request given to web application.this gives chance to browser window to engage the connections between browser window and web servers for long time and to keep them in idle state for long time.This may create the situation of reaching to maximum connections of web server even though most of the connections in clients are idle.

If you grab the MVC Futures assembly (which I would highly recommend) you can then use a generic when creating the ActionLink and a lambda to construct the route:

<%=Html.ActionLink<Product>(c => c.Action( o.Value ), "Details" ) %>

You can get the futures assembly here: http://aspnet.codeplex.com/Release/ProjectReleases.aspx?ReleaseId=24471

Kinda related, you might want to look at Shuttle (http://fitztrev.github.io/shuttle/), it's a SSH shortcut menu for OSX.

>>> l = raw_input()
1 2 3 4 5 6 7 8 9 10
>>> l = l.split()
>>> l.pop(0)
'1'
>>> sum(map(int, l)) #or simply sum(int(x) for x in l) , you've to convert the elements to integer first, before applying sum()
54

You can try

Random r = new Random();
int rInt = r.Next(0, 100); //for ints
int range = 100;
double rDouble = r.NextDouble()* range; //for doubles

Have a look at

Random Class, Random.Next Method (Int32, Int32) and Random.NextDouble Method

Here is what worked for me: (I got this answer from https://productforums.google.com/forum/#!topic/chrome/MJjuK65Exkg)

1. Unpin Chrome icon from task bar so it is on the desktop.
2. Right mouse click on said icon and left click on Properties.
3. Click on Shortcuts tab 4A. In Target window, add this exact text: [space]--disable-gpu" 4B. The end of the text string in the Target window should now read: ...chrome.exe" --disable-gpu"
4. Double click on the desktop icon and Chrome should open correctly. If you want, you may pin this icon to the taskbar.
5. Left single click on the "Customize" icon in the top right, which is the 3 horizontal lines icon. Select "Settings" from the list.
6. Select "Show advanced settings..." at the bottom.
7. Deselect "Use hardware acceleration when available."

Try this:

preg_replace('/[^0-9]/', '', '604-619-5135');

preg_replace uses PCREs which generally start and end with a /.

Since May 23, 2018 update, when you're using a firebase dependency, you must include the firebase-core dependency, too.

If adding it, you still having the error, try to update the gradle plugin in your gradle-wrapper.properties to 4.5 version:

distributionUrl=https\://services.gradle.org/distributions/gradle-4.5-all.zip

and resync the project.

Outline indeed does apply to the whole element.

Now that I see your image, here's how to achieve it.

.element {_x000D_
  padding: 5px 0;_x000D_
  background: #CCC;_x000D_
}_x000D_
.element:before {_x000D_
  content: "\a0";_x000D_
  display: block;_x000D_
  padding: 2px 0;_x000D_
  line-height: 1px;_x000D_
  border-top: 1px dashed #000; _x000D_
}_x000D_
.element p {_x000D_
  padding: 0 10px;_x000D_
}

<div class="element">_x000D_
  <p>Some content comes here...</p>_x000D_
</div>

(Or see external demo.)

All sizes and colors are just placeholders, you can change it to match the exact desired result.

Important note: .element must have display:block; (default for a div) for this to work. If it's not the case, please provide your full code, so that i can elaborate a specific answer.

This is the main difference between use git reset --hard and git reset --soft:

--soft

Does not touch the index file or the working tree at all (but resets the head to , just like all modes do). This leaves all your changed files "Changes to be committed", as git status would put it.

--hard

Resets the index and working tree. Any changes to tracked files in the working tree since are discarded.

That's not JSON at all, it's just Javascript objects. JSON is a text representation of data, that uses a subset of the Javascript syntax.

The reason that you can't find any information about manipulating JSON using jQuery is because jQuery has nothing that can do that, and it's generally not done at all. You manipulate the data in the form of Javascript objects, and then turn it into a JSON string if that is what you need. (jQuery does have methods for the conversion, though.)

What you have is simply an object that contains an array, so you can use all the knowledge that you already have. Just use data.items to access the array.

For example, to add another item to the array using dynamic values:

// The values to put in the item
var id = 7;
var name = "The usual suspects";
var type = "crime";
// Create the item using the values
var item = { id: id, name: name, type: type };
// Add the item to the array
data.items.push(item);

For those who are using Visual Studio 2017 version, it seems like the preprocessor definition required to run unsafe operations has changed. Use instead:

#define _CRT_SECURE_NO_WARNINGS

It will compile then.

I had the same problem. I found that this is because the Maven script looks at the CurrentJDK link below and finds a 1.6 JDK. Even if you install the latest JDK this is not resolved. While you could just set JAVA_HOME in your $HOME/.bash_profile script I chose to fix the symbolic link instead as follows:

ls -l /System/Library/Frameworks/JavaVM.framework/Versions/
total 64
lrwxr-xr-x  1 root  wheel   10 30 Oct 16:18 1.4 -> CurrentJDK
lrwxr-xr-x  1 root  wheel   10 30 Oct 16:18 1.4.2 -> CurrentJDK
lrwxr-xr-x  1 root  wheel   10 30 Oct 16:18 1.5 -> CurrentJDK
lrwxr-xr-x  1 root  wheel   10 30 Oct 16:18 1.5.0 -> CurrentJDK
lrwxr-xr-x  1 root  wheel   10 30 Oct 16:18 1.6 -> CurrentJDK
lrwxr-xr-x  1 root  wheel   10 30 Oct 16:18 1.6.0 -> CurrentJDK
drwxr-xr-x  9 root  wheel  306 11 Nov 21:20 A
lrwxr-xr-x  1 root  wheel    1 30 Oct 16:18 Current -> A
lrwxr-xr-x  1 root  wheel   59 30 Oct 16:18 CurrentJDK -> /System/Library/Java/JavaVirtualMachines/1.6.0.jdk/Contents

Notice that CurrentJDK points at 1.6.0.jdk

To fix it I ran the following commands (you should check your installed version and adapt accordingly).

sudo rm /System/Library/Frameworks/JavaVM.framework/Versions/CurrentJDK
sudo ln -s /Library/Java/JavaVirtualMachines/jdk1.7.0_51.jdk/Contents/ /System/Library/Frameworks/JavaVM.framework/Versions/CurrentJDK

postgresql get seconds difference between timestamps

SELECT (
    (extract (epoch from (
        '2012-01-01 18:25:00'::timestamp - '2012-01-01 18:25:02'::timestamp
                         )
             )
    )
)::integer

which prints:

-2

Because the timestamps are two seconds apart. Take the number and divide by 60 to get minutes, divide by 60 again to get hours.

In my case it was related to a .ps1 referral inside the ps1 script which was not signed (you need to unblock it at the file properties) , also I added as first line:

Set-ExecutionPolicy -ExecutionPolicy Unrestricted -Force

Then it worked

Import specific methods inside of curly brackets

import { map, tail, times, uniq } from 'lodash';

Pros:

• Only one import line(for a decent amount of functions)
• More readable usage: map() instead of _.map() later in the javascript code.

Cons:

• Every time we want to use a new function or stop using another - it needs to be maintained and managed

Copied from:The Correct Way to Import Lodash Libraries - A Benchmark article written by Alexander Chertkov.

If the IGNORE statement won't work like in my case, you can use the below statement:

CREATE TABLE your_table_deduped LIKE your_table;


INSERT your_table_deduped
SELECT *
FROM your_table
GROUP BY index1_id,
         index2_id;

RENAME TABLE your_table TO your_table_with_dupes;

RENAME TABLE your_table_deduped TO your_table;

#OPTIONAL
ALTER TABLE `your_table` ADD UNIQUE `unique_index` (`index1_id`, `index2_id`);

#OPTIONAL
DROP TABLE your_table_with_dupes;

You can add it to php.ini and it should work - just tested it on PHP 5.3.6.

For those who need the same feature in IE 8, this is how I solved the problem:

  var myImage = $('<img/>');

               myImage.attr('width', 300);
               myImage.attr('height', 300);
               myImage.attr('class', "groupMediaPhoto");
               myImage.attr('src', photoUrl);

I could not force IE8 to use object in constructor.

To see the dynamic SQL generated, change to text mode (_shortcut: Ctrl-T), then use SELECT

PRINT LEN(@Query) -- Prints out 4273, which is correct as far as I can tell
--SET NOCOUNT ON
SELECT @Query

As for sp_executesql, try this (in text mode), it should show the three aaaaa...'s the middle one being the longest with 'SELECT ..' added. Watch the Ln... Col.. indicator in the status bar at bottom right showing 4510 at the end of the 2nd output.

declare @n nvarchar(max)
set @n = REPLICATE(convert(nvarchar(max), 'a'), 4500)
SET @N = 'SELECT ''' + @n + ''''
print @n   -- up to 4000
select @n  -- up to max
exec sp_Executesql @n

You repository is bare, i.e. it does not have a working tree attached to it. You can clone it locally to create a working tree for it, or you could use one of several other options to tell Git where the working tree is, e.g. the --work-tree option for single commands, or the GIT_WORK_TREE environment variable. There is also the core.worktree configuration option but it will not work in a bare repository (check the man page for what it does).

# git --work-tree=/path/to/work/tree checkout master
# GIT_WORK_TREE=/path/to/work/tree git status

I know I'm late to the party but I thought I'd add what I ended up using for this - which is to simply check if the file upload input does not contain a truthy value with the not operator & JQuery like so:

if (!$('#videoUploadFile').val()) {
  alert('Please Upload File');
}

Note that if this is in a form, you may also want to wrap it with the following handler to prevent the form from submitting:

$(document).on("click", ":submit", function (e) {

  if (!$('#videoUploadFile').val()) {
  e.preventDefault();
  alert('Please Upload File');
  }

}

This is the easiest way :

step 1) install Spring Tool Suite (STS) for eclipse (version 3.7.0RELEASE or above) To do this you can go to Help >> eclipse market place , then type Spring Tool suite in search box.

step 2) now go to file >> new >> spring project as shown in the image below

step 3)now choose the template as "spring MVC Project" and give a name to your project on the top as shown below ( I named it 'SpringProject')

step 4)now give a base package name like this

and that is . The project will be created in a few minutes and Now you can right click on it and run on server.

If you are using Express > 4.0, you could go for serve-favicon

There are 3 ways to do this:

1. Define the Series names directly

Right-click on the Chart and click Select Data then edit the series names directly as shown below.

You can either specify the values directly e.g. Series 1 or specify a range e.g. =A2

2. Create a chart defining upfront the series and axis labels

Simply select your data range (in similar format as I specified) and create a simple bar chart. The labels should be defined automatically.

3. Define the legend (series names) using VBA

Similarly you can define the series names dynamically using VBA. A simple example below:

ActiveChart.ChartArea.Select
ActiveChart.FullSeriesCollection(1).Name = "=""Hello"""

This will redefine the first series name. Just change the index from (1) to e.g. (2) and so on to change the following series names. What does the VBA above do? It sets the series name to Hello as "=""Hello""" translates to ="Hello" (" have to be escaped by a preceding ").

Re-migrate approach for a cleaner plate.

This can painlessly be done IF other apps do not foreign key models from the app to be renamed. Check and make sure their migration files don't list any migrations from this one.

1. Backup your database. Dump all tables with a) data + schema for possible circular dependencies, and b) just data for reloading.
2. Run your tests.
3. Check all code into VCS.
4. Delete the database tables of the app to be renamed.
5. Delete the permissions: delete from auth_permission where content_type_id in (select id from django_content_type where app_label = '<OldAppName>')
6. Delete content types: delete from django_content_type where app_label = '<OldAppName>'
7. Rename the folder of the app.
8. Change any references to your app in their dependencies, i.e. the app's views.py, urls.py , 'manage.py' , and settings.py files.
9. Delete migrations: delete from django_migrations where app = '<OldAppName>'
10. If your models.py 's Meta Class has app_name listed, make sure to rename that too (mentioned by @will).
11. If you've namespaced your static or templates folders inside your app, you'll also need to rename those. For example, rename old_app/static/old_app to new_app/static/new_app.
12. If you defined app config in apps.py; rename those, and rename their references in settings.INSTALLED_APPS
13. Delete migration files.
14. Re-make migrations, and migrate.
15. Load your table data from backups.

Here's a lightweight solution I use which allows the application to bring an already existing window to the foreground without resorting to custom windows messages or blindly searching process names.

[DllImport("user32.dll")]
static extern bool SetForegroundWindow(IntPtr hWnd);

static readonly string guid = "<Application Guid>";

static void Main()
{
    Mutex mutex = null;
    if (!CreateMutex(out mutex))
        return;

    // Application startup code.

    Environment.SetEnvironmentVariable(guid, null, EnvironmentVariableTarget.User);
}

static bool CreateMutex(out Mutex mutex)
{
    bool createdNew = false;
    mutex = new Mutex(false, guid, out createdNew);

    if (createdNew)
    {
        Process process = Process.GetCurrentProcess();
        string value = process.Id.ToString();

        Environment.SetEnvironmentVariable(guid, value, EnvironmentVariableTarget.User);
    }
    else
    {
        string value = Environment.GetEnvironmentVariable(guid, EnvironmentVariableTarget.User);
        Process process = null;
        int processId = -1;

        if (int.TryParse(value, out processId))
            process = Process.GetProcessById(processId);

        if (process == null || !SetForegroundWindow(process.MainWindowHandle))
            MessageBox.Show("Unable to start application. An instance of this application is already running.");
    }

    return createdNew;
}

Edit: You can also store and initialize mutex and createdNew statically, but you'll need to explicitly dispose/release the mutex once you're done with it. Personally, I prefer keeping the mutex local as it will be automatically disposed of even if the application closes without ever reaching the end of Main.

They are the same concepts, apart from the NULL value returned.

See below:

declare @table1 table( col1 int, col2 int );
insert into @table1 select 1, 11 union all select 2, 22;

declare @table2 table ( col1 int, col2 int );
insert into @table2 select 10, 101 union all select 2, 202;

select
    t1.*,
    t2.*
from @table1 t1
full outer join @table2 t2 on t1.col1 = t2.col1
order by t1.col1, t2.col1;

/* full outer join

2           22          2           202
*/

select
    t1.*,
    t2.*
from @table1 t1
cross join @table2 t2
order by t1.col1, t2.col1;

/* cross join
col1        col2        col1        col2
----------- ----------- ----------- -----------
1           11          2           202
1           11          10          101
2           22          2           202

You have to explicitly define the constructor in B and explicitly call the constructor for the parent.

B(int x) : A(x) { }

or

B() : A(5) { }

You can't move the mouse pointer using javascript, and thus for obvious security reasons. The best way to achieve this effect would be to actually place the control under the mouse pointer.

Try to login via the terminal using the following command:

mysql -u root -p

It will then prompt for your password. If this fails, then definitely the username or password is incorrect. If this works, then your database's password needs to be enclosed in quotes:

database_password: "0000"

Test this code, I think solve your problem:

event.stopPropagation();

An inner class has access to all members of the outer class, but it does not have an implicit reference to a parent class instance (unlike some weirdness with Java). So if you pass a reference to the outer class to the inner class, it can reference anything in the outer class instance.

Create a theme as below.

log4j2 has a very flexible configuration system (which IMHO is more a distraction than a help), you can even use JSON. See https://logging.apache.org/log4j/2.x/manual/configuration.html for a reference.

Personally, I just recently started using log4j2, but I'm tending toward the "strict XML" configuration (that is, using attributes instead of element names), which can be schema-validated.

Here is my simple example using autoconfiguration and strict mode, using a "Property" for setting the filename:

<?xml version="1.0" encoding="UTF-8"?>
<Configuration monitorinterval="30" status="info" strict="true">
    <Properties>
        <Property name="filename">log/CelsiusConverter.log</Property>
    </Properties>
    <Appenders>
        <Appender type="Console" name="Console">
            <Layout type="PatternLayout" pattern="%d %p [%t] %m%n" />
        </Appender>
        <Appender type="Console" name="FLOW">
            <Layout type="PatternLayout" pattern="%C{1}.%M %m %ex%n" />
        </Appender>
        <Appender type="File" name="File" fileName="${filename}">
            <Layout type="PatternLayout" pattern="%d %p %C{1.} [%t] %m%n" />
        </Appender>
    </Appenders>
    <Loggers>
        <Root level="debug">
            <AppenderRef ref="File" />
            <AppenderRef ref="Console" />
            <!-- Use FLOW to trace down exact method sending the msg -->
            <!-- <AppenderRef ref="FLOW" /> -->
        </Root>
    </Loggers>
</Configuration>

In Addition you can use XPath selector in the following way (easy way to select specific nodes):

XmlDocument doc = new XmlDocument();
doc.Load("test.xml");

var found = doc.DocumentElement.SelectNodes("//book[@title='Barry Poter']"); // select all Book elements in whole dom, with attribute title with value 'Barry Poter'

// Retrieve your data here or change XML here:
foreach (XmlNode book in nodeList)
{
  book.InnerText="The story began as it was...";
}

Console.WriteLine("Display XML:");
doc.Save(Console.Out);

That's not how to add an item to a string. This:

newinv=inventory+str(add)

Means you're trying to concatenate a list and a string. To add an item to a list, use the list.append() method.

inventory.append(add) #adds a new item to inventory
print(inventory) #prints the new inventory

Hope this helps!

The listen socket on a server can use linger with time 0 to have access to binding back to the socket immediately and to reset any clients whose connections are not yet finished connecting. TIME_WAIT is something that is only interesting when you have a multi-path network and can end up with miss-ordered packets or otherwise are dealing with odd network packet ordering/arrival-timing.

var dateObject = $("#datePickerInput").datepicker('getDate');
$.datepicker.formatDate('dd MM, yy', dateObject);

It means exactly what it says. You're trying to insert a value into a column that has a FK constraint on it that doesn't match any values in the lookup table.

Try this

$('#add_here').text('new-dynamic-text');

Here's a compact Objective-C version as a Category on NSData. It takes some thinking about...

 // tackle the source in 3's as conveniently 4 Base64 nibbles fit into 3 bytes
 for (int i=0; i<srcLen; i += 3)
 {
  // for each output nibble
  for (int nib=0; nib<4; nib++)

   // nibble:nib from char:byt
   int byt = (nib == 0)?0:nib-1;

Padding can be added if required by making the scope of 'byt' wider and appending 'dest' with (2-byt) "=" characters before returning.

A Category can then be added to NSString, thus:

@implementation NSString (StringUtils)

- (NSString *)newStringInBase64FromString
{
 NSData *theData = [NSData dataWithBytes:[self UTF8String] length:[self length]]; 

 return [theData newStringInBase64FromData];
}

@end

Find the file "config.inc.php" under your phpMyAdmin directory and edit the following lines:

$cfg['Servers'][$i]['auth_type'] = 'config'; // config, http, cookie

$cfg['Servers'][$i]['user'] = 'root'; // MySQL user

$cfg['Servers'][$i]['password'] = 'TYPE_YOUR_PASSWORD_HERE'; // MySQL password

Note that the password used in the 'password' field must be the same for the MySQL root password. Also, you should check if root login is allowed in this line:

$cfg['Servers'][$i]['AllowRoot']     = TRUE;        // true = allow root login

This way you have your root password set.

Get all views of a view plus its children recursively in Kotlin:

private fun View.getAllViews(): List<View> {
    if (this !is ViewGroup || childCount == 0) return listOf(this)

    return children
            .toList()
            .flatMap { it.getAllViews() }
            .plus(this as View)
}

DependencyObject parent = ExVisualTreeHelper.FindVisualParent<UserControl>(this);

select Id, StartDate,
Case IsNull (StartDate , '01/01/1800')
When '01/01/1800' then
  'Awaiting'
Else
  'Approved'
END AS StartDateStatus

You can use format keyword as well for this.Format method will replace {} placeholder to the variable which you passed to the format method as an argument.

if re.search(r"\b(?=\w)**{}**\b(?!\w)".**format(TEXTO)**, subject, re.IGNORECASE):
    # Successful match**strong text**
else:
    # Match attempt failed

www.example.com:443:0 server certificate does NOT include an ID which matches the server name

I was getting this error when trying to start Apache, there is no error with Apache. It's an dependency error on windows 8 - probably the same for 7. Just right click and run as Admin :)

If you're still getting an error check your Antivirus/Firewall is not blocking Xampp or port 443.

It looks like it is an extension method (in System.Net.Http.Formatting):

HttpContentExtensions Class

Update:

PM> install-package Microsoft.AspNet.WebApi.Client

According to the System.Net.Http.Formatting NuGet package page, the System.Net.Http.Formatting package is now legacy and can instead be found in the Microsoft.AspNet.WebApi.Client package available on NuGet here.

If owner names differ, sort by them. Otherwise, use publication name for tiebreaker.

function mysortfunction(a, b) {

  var o1 = a[3].toLowerCase();
  var o2 = b[3].toLowerCase();

  var p1 = a[1].toLowerCase();
  var p2 = b[1].toLowerCase();

  if (o1 < o2) return -1;
  if (o1 > o2) return 1;
  if (p1 < p2) return -1;
  if (p1 > p2) return 1;
  return 0;
}

.poll() will update the return code.

Try

child = sp.Popen(openRTSP + opts.split(), stdout=sp.PIPE)
returnCode = child.poll()

In addition, after .poll() is called the return code is available in the object as child.returncode.

I see that this problem was discussed some time ago, but if anyone 'll meet with this again, here is my solution:

In your *.cshtml View file:

<script>
var data = JsFunction("@Html.Raw(Model.Path)");
$(function () {
    $("#btn").click(function () {
        var model = { Id: '@Html.Raw(Model.Id)', Data: data }
        $.ajax({
            type: "POST",
            url: "/Controller/Action",
            data: model,
            datatype: "html",
            success: function() {
                console.log('Success');
            }
        });
    });
});
</script>

JavaScript variable model is something that I need to pass to Razor ViewModel. It can be done with ajax request. You just need to have proper argument/s in your action, that matches Json object created in JavaScript.

Hope it'll help someone!

strtotime will work that out. the dates are just not the same and all in us-format.

<?php
$e1 = strtotime("2013-07-22T12:00:03Z");
echo date('y.m.d H:i', $e1);
echo "2013-07-22T12:00:03Z";

$e2 = strtotime("2013-07-23T18:18:15Z");
echo date ('y.m.d H:i', $e2);
echo "2013-07-23T18:18:15Z";

$e1 = strtotime("2013-07-21T23:57:04Z");
echo date ('y.m.d H:i', $e2);
echo "2013-07-21T23:57:04Z";
?>

# mysqladmin -u root -p status

Output:

Enter password:
Uptime: 4  Threads: 1  Questions: 62  Slow queries: 0  Opens: 51  Flush tables: 1  Open tables: 45  Queries per second avg: 15.500

It means MySQL serer is running

If server is not running then it will dump error as follows

# mysqladmin -u root -p status

Output :

mysqladmin: connect to server at 'localhost' failed
error: 'Can't connect to local MySQL server through socket '/var/run/mysqld/mysqld.sock' (2)'
Check that mysqld is running and that the socket: '/var/run/mysqld/mysqld.sock' exists!

So Under Debian Linux you can type following command

# /etc/init.d/mysql status

Another possible cause is that the clock of your machine is not synced (e.g. on Raspberry Pi). Check the current date/time using:

$ date

If the date and/or time is incorrect, try to update using:

$ sudo ntpdate -u time.nist.gov

You can use not(expression) function

not() is a function in xpath (as opposed to an operator)

Example:

//a[not(contains(@id, 'xx'))]

OR

expression != true()

CurrPorts is network monitoring software that displays the list of all currently opened TCP/IP and UDP ports on your local computer.

Other answers already provide information for iOS 7 and older, however UIAlertView is deprecated in iOS 8.

In iOS 8+ you should use UIAlertController. It is a replacement for both UIAlertView and UIActionSheet. Documentation: UIAlertController Class Reference. And a nice article on NSHipster.

To create a simple Alert View you can do the following:

UIAlertController *alertController = [UIAlertController alertControllerWithTitle:@"Title"
                                                                         message:@"Message"
                                                                  preferredStyle:UIAlertControllerStyleAlert];
//We add buttons to the alert controller by creating UIAlertActions:
UIAlertAction *actionOk = [UIAlertAction actionWithTitle:@"Ok"
                                                   style:UIAlertActionStyleDefault
                                                 handler:nil]; //You can use a block here to handle a press on this button
[alertController addAction:actionOk];
[self presentViewController:alertController animated:YES completion:nil];

Swift 3 / 4 / 5:

let alertController = UIAlertController(title: "Title", message: "Message", preferredStyle: .alert)
//We add buttons to the alert controller by creating UIAlertActions:
let actionOk = UIAlertAction(title: "OK",
    style: .default,
    handler: nil) //You can use a block here to handle a press on this button

alertController.addAction(actionOk)

self.present(alertController, animated: true, completion: nil)

Note, that, since it was added in iOS 8, this code won't work on iOS 7 and older. So, sadly, for now we have to use version checks like so:

NSString *alertTitle = @"Title";
NSString *alertMessage = @"Message";
NSString *alertOkButtonText = @"Ok";

if (@available(iOS 8, *)) {
    UIAlertView *alertView = [[UIAlertView alloc] initWithTitle:alertTitle
                                                        message:alertMessage
                                                       delegate:nil
                                              cancelButtonTitle:nil
                                              otherButtonTitles:alertOkButtonText, nil];
    [alertView show];
}
else {
    UIAlertController *alertController = [UIAlertController alertControllerWithTitle:alertTitle
                                                                             message:alertMessage
                                                                      preferredStyle:UIAlertControllerStyleAlert];
    //We add buttons to the alert controller by creating UIAlertActions:
    UIAlertAction *actionOk = [UIAlertAction actionWithTitle:alertOkButtonText
                                                       style:UIAlertActionStyleDefault
                                                     handler:nil]; //You can use a block here to handle a press on this button
    [alertController addAction:actionOk];
    [self presentViewController:alertController animated:YES completion:nil];
}

Swift 3 / 4 / 5:

let alertTitle = "Title"
let alertMessage = "Message"
let alertOkButtonText = "Ok"

if #available(iOS 8, *) {
    let alertController = UIAlertController(title: alertTitle, message: alertMessage, preferredStyle: .alert)
    //We add buttons to the alert controller by creating UIAlertActions:
    let actionOk = UIAlertAction(title: alertOkButtonText,
        style: .default,
        handler: nil) //You can use a block here to handle a press on this button

    alertController.addAction(actionOk)
    self.present(alertController, animated: true, completion: nil)
}
else {
    let alertView = UIAlertView(title: alertTitle, message: alertMessage, delegate: nil, cancelButtonTitle: nil, otherButtonTitles: alertOkButtonText)
    alertView.show()
}

UPD: updated for Swift 5. Replaced outdated class presence check with availability check in Obj-C.

jnettop is another candidate.

I have implemented LIS in java using Dynamic Programming and Memoization. Along with the code I have done complexity calculation i.e. why it is O(n Log(base2) n). As I feel theoretical or logical explanations are good but practical demonstration is always better for understanding.

package com.company.dynamicProgramming;

import java.util.HashMap;
import java.util.Map;

public class LongestIncreasingSequence {

    static int complexity = 0;

    public static void main(String ...args){


        int[] arr = {10, 22, 9, 33, 21, 50, 41, 60, 80};
        int n = arr.length;

        Map<Integer, Integer> memo = new HashMap<>();

        lis(arr, n, memo);

        //Display Code Begins
        int x = 0;
        System.out.format("Longest Increasing Sub-Sequence with size %S is -> ",memo.get(n));
        for(Map.Entry e : memo.entrySet()){

            if((Integer)e.getValue() > x){
                System.out.print(arr[(Integer)e.getKey()-1] + " ");
                x++;
            }
        }
        System.out.format("%nAnd Time Complexity for Array size %S is just %S ", arr.length, complexity );
        System.out.format( "%nWhich is equivalent to O(n Log n) i.e. %SLog(base2)%S is %S",arr.length,arr.length, arr.length * Math.ceil(Math.log(arr.length)/Math.log(2)));
        //Display Code Ends

    }



    static int lis(int[] arr, int n, Map<Integer, Integer> memo){

        if(n==1){
            memo.put(1, 1);
            return 1;
        }

        int lisAti;
        int lisAtn = 1;

        for(int i = 1; i < n; i++){
            complexity++;

            if(memo.get(i)!=null){
                lisAti = memo.get(i);
            }else {
                lisAti = lis(arr, i, memo);
            }

            if(arr[i-1] < arr[n-1] && lisAti +1 > lisAtn){
                lisAtn = lisAti +1;
            }
        }

        memo.put(n, lisAtn);
        return lisAtn;

    }
}

While I ran the above code -

Longest Increasing Sub-Sequence with size 6 is -> 10 22 33 50 60 80 
And Time Complexity for Array size 9 is just 36 
Which is equivalent to O(n Log n) i.e. 9Log(base2)9 is 36.0
Process finished with exit code 0

jQuery doesn't have a convenient function for this. You need to combine contents(), which will give just child nodes but includes text nodes, with find(), which gives all descendant elements but no text nodes. Here's what I've come up with:

var getTextNodesIn = function(el) {
    return $(el).find(":not(iframe)").addBack().contents().filter(function() {
        return this.nodeType == 3;
    });
};

getTextNodesIn(el);

Note: If you're using jQuery 1.7 or earlier, the code above will not work. To fix this, replace addBack() with andSelf(). andSelf() is deprecated in favour of addBack() from 1.8 onwards.

This is somewhat inefficient compared to pure DOM methods and has to include an ugly workaround for jQuery's overloading of its contents() function (thanks to @rabidsnail in the comments for pointing that out), so here is non-jQuery solution using a simple recursive function. The includeWhitespaceNodes parameter controls whether or not whitespace text nodes are included in the output (in jQuery they are automatically filtered out).

Update: Fixed bug when includeWhitespaceNodes is falsy.

function getTextNodesIn(node, includeWhitespaceNodes) {
    var textNodes = [], nonWhitespaceMatcher = /\S/;

    function getTextNodes(node) {
        if (node.nodeType == 3) {
            if (includeWhitespaceNodes || nonWhitespaceMatcher.test(node.nodeValue)) {
                textNodes.push(node);
            }
        } else {
            for (var i = 0, len = node.childNodes.length; i < len; ++i) {
                getTextNodes(node.childNodes[i]);
            }
        }
    }

    getTextNodes(node);
    return textNodes;
}

getTextNodesIn(el);

I created a Bootstrap plugin that incorporates a lot of the ideas posted here.

Demo on Bootply: http://www.bootply.com/cObcYInvpq

Github: https://github.com/jhaygt/bootstrap-multimodal

It also addresses the issue with successive modals causing the backdrop to become darker and darker. This ensures that only one backdrop is visible at any given time:

if(modalIndex > 0)
    $('.modal-backdrop').not(':first').addClass('hidden');

The z-index of the visible backdrop is updated on both the show.bs.modal and hidden.bs.modal events:

$('.modal-backdrop:first').css('z-index', MultiModal.BASE_ZINDEX + (modalIndex * 20));

That depends. Is it just a variable (in a method)? Or a class-member?

If it's just a variable you'll get an error that no value has been set when trying to read from it without first assinging it a value.

If it's a class-member it will be initialized to null by the VM.

You should use UsedRange instead like so:

Sub test()
    Dim sh As Worksheet
    Dim rn As Range
    Set sh = ThisWorkbook.Sheets("Sheet1")

    Dim k As Long

    Set rn = sh.UsedRange
    k = rn.Rows.Count + rn.Row - 1
End Sub

The + rn.Row - 1 part is because the UsedRange only starts at the first row and column used, so if you have something in row 3 to 10, but rows 1 and 2 is empty, rn.Rows.Count would be 8

If you didn't want to sign up for a service, I'd probably go back to the exchanges themselves; most of them aren't CAPTCHAed yet...

Do this below. Worked for me. I took values from a select box and another textbox. Then on button click I took the entire data in Javascript function and redirected using javascript.

//Search Form
$(document).ready (function($){
    $("#searchbtn").click(function showAlert(e){
        e.preventDefault();
        var cat = $('#category').val();
        var srch = $('#srch').val();

        if(srch==""){
            alert("Search is empty :(");
        }
        else{
            var url = baseurl+'categories/search/'+cat+'/'+srch;            
            window.location.href=url;
        }
    });
});

The above code worked for me.

If you know what you're doing, you can define a class with implicit operators to convert between the alias class and the actual class.

class TypedefString // Example with a string "typedef"
{
    private string Value = "";
    public static implicit operator string(TypedefString ts)
    {
        return ((ts == null) ? null : ts.Value);
    }
    public static implicit operator TypedefString(string val)
    {
        return new TypedefString { Value = val };
    }
}

I don't actually endorse this and haven't ever used something like this, but this could probably work for some specific circumstances.

If you're using express > 4.16, you can use express.json() and express.urlencoded()

The express.json() and express.urlencoded() middleware have been added to provide request body parsing support out-of-the-box. This uses the expressjs/body-parser module module underneath, so apps that are currently requiring the module separately can switch to the built-in parsers.

Source Express 4.16.0 - Release date: 2017-09-28

With this,

const bodyParser  = require('body-parser');

app.use(bodyParser.urlencoded({ extended: true }));
app.use(bodyParser.json());

becomes,

const express = require('express');

app.use(express.urlencoded({ extended: true }));
app.use(express.json());

Try this, it's simple enough to justify the time...

This is for Win32 API, written in C. Translate it as you need...

case WM_NOTIFY:{
  HWND X=FindWindow("#32770",NULL);
  if(GetParent(X)==H_frame){int Px,Py,Sx,Sy; RECT R1,R2;
    GetWindowRect(hwnd,&R1); GetWindowRect(X,&R2);
    Sx=R2.right-R2.left,Px=R1.left+(R1.right-R1.left)/2-Sx/2;
    Sy=R2.bottom-R2.top,Py=R1.top+(R1.bottom-R1.top)/2-Sy/2;
    MoveWindow(X,Px,Py,Sx,Sy,1);
  }
} break;

Add that to the WndProc code... You can set position as you like, in this case it just centres over the main program window. It will do this for any messagebox, or file open/save dialog, and likely some other native controls. I'm not sure, but I think you may need to include COMMCTRL or COMMDLG to use this, at least, you will if you want open/save dialogs.

I experimented with looking at the notify codes and hwndFrom of NMHDR, then decided it was just as effective, and far easier, not to. If you really want to be very specific, tell FindWindow to look for a unique caption (title) you give to the window you want it to find.

This fires before the messagebox is drawn onscreen, so if you set a global flag to indicate when action is done by your code, and look for a unique caption, you be sure that actions you take will only occur once (there will likely be multiple notifiers). I haven't explored this in detail, but I managed get CreateWindow to put an edit box on a messagebox dialog. It looked as out of place as a rat's ear grafted onto the spine of a cloned pig, but it works. Doing things this way may be far easier than having to roll your own.

Crow.

EDIT: Small correction to make sure that the right window is handled. Make sure that parent handles agree throughout, and this should work ok. It does for me, even with two instances of the same program...

If you think that there is a conflict you can use jQuery.noConflict() in your code. Details are in the docs.

REFERENCING MAGIC - SHORTCUTS FOR JQUERY

If you don't like typing the full "jQuery" all the time, there are some alternative shortcuts:

Reassign jQuery to another shortcut var $j = jQuery; (This might be the best approach if you wish to use different libraries) Use the following technique, which allows you to use $ inside of a block of code without permanently overwriting $:

(function($) { /* some code that uses $ */ })(jQuery)

Note: If you use this technique, you will not be able to use Prototype methods inside this capsuled function that expect $ to be Prototype's $, so you're making a choice to use only jQuery in that block. Use the argument to the DOM ready event:

jQuery(function($) { /*some code that uses $ */ });

Note: Again, inside that block you can't use Prototype methods

Thats from the end of the docs and might be useful to you

To answer your question, yes. The other have answered that part, but it also seems like you're asking if that's the best way to do it.

It would probably depend on what you are doing. Typically you would have a user click what items they want to buy (ordering for example). Then they would hit a buy or checkout button. Then the form would send off to a page and process the result. You could do all of that with a cookie but I would find it to be more difficult.

You may want to consider posting your second question in another topic.

use jQuery.noConflict()

var j = jQuery.noConflict();
j(document).ready(function(){
    j('#datetimepicker').datepicker();
})

Hope this Helps:

    String timestamp = new SimpleDateFormat("yyyy-mm-dd 'T' HH:MM:SS.mmm-HH:SS").format(new Date());
    return timestamp;
}

Try

ifstream my_file("test.txt");
if (my_file)
{
 // do stuff
}

From: How to check if a file exists and is readable in C++?

or you could use boost functions.

Several reasons:

1. String.Format() is very powerful. You can use simple format indicators (like fixed width, currency, character lengths, etc) right in the format string. You can even create your own format providers for things like expanding enums, mapping specific inputs to much more complicated outputs, or localization.
2. You can do some powerful things by putting format strings in configuration files.
3. String.Format() is often faster, as it uses a StringBuilder and an efficient state machine behind the scenes, whereas string concatenation in .Net is relatively slow. For small strings the difference is negligible, but it can be noticable as the size of the string and number of substituted values increases.
4. String.Format() is actually more familiar to many programmers, especially those coming from backgrounds that use variants of the old C printf() function.

Finally, don't forget StringBuilder.AppendFormat(). String.Format() actually uses this method behind the scenes*, and going to the StringBuilder directly can give you a kind of hybrid approach: explicitly use .Append() (analogous to concatenation) for some parts of a large string, and use .AppendFormat() in others.

_{* [edit] Original answer is now 8 years old, and I've since seen an indication this may have changed when string interpolation was added to .Net. However, I haven't gone back to the reference source to verify the change yet.}

Placing @Transient on getter with private field worked for me.

private String name;

    @Transient
    public String getName() {
        return name;
    }

    public void setName(String name) {
        this.name = name;
    }

mkdir [-switch] foldername

-p is a switch which is optional, it will create subfolder and parent folder as well even parent folder doesn't exist.

From the man page:

-p, --parents no error if existing, make parent directories as needed

Example:

mkdir -p storage/framework/{sessions,views,cache}

This will create subfolder sessions,views,cache inside framework folder irrespective of 'framework' was available earlier or not.

OP here, I have learned a lot more about node since I first asked this question. Though Dmitry's answer was very helpful, what ultimately did it for me is to install node with the correct permissions.

I highly recommend not installing node using any package managers, but rather to compile it yourself so that it resides in a local directory with normal permissions.

This article provides a very clear step-by-step instruction of how to do so:

Building workspace is about incremental build of any evolution detected in one of the opened projects in the currently used workspace.

You can also disable it through the menu "Project / Build automatically".

But I would recommend first to check:

• if a Project Clean all / Build result in the same kind of long wait (after disabling this option)
• if you have (this time with building automatically activated) some validation options you could disable to see if they have an influence on the global compilation time (Preferences / Validations, or Preferences / XML / ... if you have WTP installed)
• if a fresh eclipse installation referencing the same workspace (see this eclipse.ini for more) results in the same issue (with building automatically activated)

Note that bug 329657 (open in 2011, in progress in 2014) is about interrupting a (too lengthy) build, instead of cancelling it:

There is an important difference between build interrupt and cancel.

• When a build is cancelled, it typically handles this by discarding incremental build state and letting the next build be a full rebuild. This can be quite expensive in some projects.
  As a user I think I would rather wait for the 5 second incremental build to finish rather than cancel and result in a 30 second rebuild afterwards.

• The idea with interrupt is that a builder could more efficiently handle interrupt by saving its intermediate state and resuming on the next invocation.
  In practice this is hard to implement so the most common boundary is when we check for interrupt before/after calling each builder in the chain.
