Following code shows an easy way to read all phone numbers and names:

Cursor phones = getContentResolver().query(ContactsContract.CommonDataKinds.Phone.CONTENT_URI, null,null,null, null);
while (phones.moveToNext())
{
  String name=phones.getString(phones.getColumnIndex(ContactsContract.CommonDataKinds.Phone.DISPLAY_NAME));
  String phoneNumber = phones.getString(phones.getColumnIndex(ContactsContract.CommonDataKinds.Phone.NUMBER));

}
phones.close();

NOTE: getContentResolver is a method from the Activity context.

public void onActivityResult(int requestCode, int resultCode, Intent intent) 
{
  if (requestCode == PICK_CONTACT && intent != null) //here check whether intent is null R not
  {  
  }
}

because without selecting any contact it will give an exception. so better to check this condition.

So far this format is what is working for me (not the best performance though):

SELECT TOP {desired amount of rows} * 
FROM (SELECT *, ROW_NUMBER() OVER (ORDER BY {order columns} asc)__row__ FROM {table})tmp
WHERE __row__ > {offset row count}

A note on the side, paginating over dynamic data can lead to strange/unexpected results.

I just wanted to add, Apache Commons IO has stream support utilities to perform the copy. (Btw, what do you mean by placing the file into an inputstream? Can you show us your code?)

Edit:

Okay, what do you want to do with the contents of the item? There is an item.get() which returns the entire thing in a byte array.

Edit2

item.getSize() will return the uploaded file size.

its on you ul in the file http://ratest4.com/wp-content/themes/HarnettArts-BP-2010/style.css on line 252

add this to your css

ul{
     list-style:none;
}

"^" For the begining of the line "$" for the end of it. Eg.:

var re = /^abc$/;

Would match "abc" but not "1abc" or "abc1". You can learn more at https://developer.mozilla.org/en-US/docs/Web/JavaScript/Guide/Regular_Expressions

We can create a closure for the button and use that in cellForRowAtIndexPath

class ClosureSleeve {
  let closure: () -> ()

  init(attachTo: AnyObject, closure: @escaping () -> ()) {
    self.closure = closure
    objc_setAssociatedObject(attachTo, "[\(arc4random())]", self,.OBJC_ASSOCIATION_RETAIN)
}

@objc func invoke() {
   closure()
 }
}

extension UIControl {
func addAction(for controlEvents: UIControlEvents = .primaryActionTriggered, action: @escaping () -> ()) {
  let sleeve = ClosureSleeve(attachTo: self, closure: action)
 addTarget(sleeve, action: #selector(ClosureSleeve.invoke), for: controlEvents)
 }
}

And then in cellForRowAtIndexPath

func tableView(tableView: UITableView, cellForRowAtIndexPath indexPath: NSIndexPath) -> UITableViewCell
{
    let cell = youtableview.dequeueReusableCellWithIdentifier(identifier) as? youCell
    cell?.selectionStyle = UITableViewCell.SelectionStyle.none//swift 4 style

      button.addAction {
       //Do whatever you want to do when the button is tapped here
        print("button pressed")
      }

    return cell
 }

Using LEFT JOIN/IS NULL:

DELETE b FROM BLOB b 
  LEFT JOIN FILES f ON f.id = b.fileid 
      WHERE f.id IS NULL

Using NOT EXISTS:

DELETE FROM BLOB 
 WHERE NOT EXISTS(SELECT NULL
                    FROM FILES f
                   WHERE f.id = fileid)

Using NOT IN:

DELETE FROM BLOB
 WHERE fileid NOT IN (SELECT f.id 
                        FROM FILES f)

Warning

Whenever possible, perform DELETEs within a transaction (assuming supported - IE: Not on MyISAM) so you can use rollback to revert changes in case of problems.

/<b>(.*?)<\/b>/g

Add g (global) flag after:

/<b>(.*?)<\/b>/g.exec(str)
             //^-----here it is 

However if you want to get all matched elements, then you need something like this:

var str = "<b>Bob</b>, I'm <b>20</b> years old, I like <b>programming</b>.";

var result = str.match(/<b>(.*?)<\/b>/g).map(function(val){
   return val.replace(/<\/?b>/g,'');
});
//result -> ["Bob", "20", "programming"] 

If an element has attributes, regexp will be:

/<b [^>]+>(.*?)<\/b>/g.exec(str)

You are looking for strongly typed enumerations, a feature available in the C++11 standard. It turns enumerations into classes with scope values.

Using your own code example, it is:

  enum class Days {Saturday, Sunday, Tuesday,Wednesday, Thursday, Friday};
  Days day = Days::Saturday;

  if (day == Days::Saturday)  {
    cout << " Today is Saturday !" << endl;
  }
  //int day2 = Days::Sunday; // Error! invalid

Using :: as accessors to enumerations will fail if targeting a C++ standard prior C++11. But some old compilers doesn't supported it, as well some IDEs just override this option, and set a old C++ std.

If you are using GCC, enable C+11 with -std=c++11 or -std=gnu11 .

Be happy!

Use checked="checked" attribute if you want your checkbox to be checked.

I just been for 3 days looking for a jquery UI and CSS solution, I merge some code I saw, fix a little, and finally (along the other codes) I could make it work!

In C, the order that you define things often matters. Either move the definition of outchar to the top, or provide a prototype at the top, like this:

#include <stdio.h> #include <stdlib.h>  void outchar(char ch);  int main() {     outchar('A');     outchar('B');     outchar('C');     return 0; }  void outchar(char ch) {     printf("%c", ch); } 

Also, you should be specifying the return type of every function. I added that for you.

How to generate a random point within a circle of radius R:

r = R * sqrt(random())
theta = random() * 2 * PI

(Assuming random() gives a value between 0 and 1 uniformly)

If you want to convert this to Cartesian coordinates, you can do

x = centerX + r * cos(theta)
y = centerY + r * sin(theta)

Why sqrt(random())?

Let's look at the math that leads up to sqrt(random()). Assume for simplicity that we're working with the unit circle, i.e. R = 1.

The average distance between points should be the same regardless of how far from the center we look. This means for example, that looking on the perimeter of a circle with circumference 2 we should find twice as many points as the number of points on the perimeter of a circle with circumference 1.

Since the circumference of a circle (2πr) grows linearly with r, it follows that the number of random points should grow linearly with r. In other words, the desired probability density function (PDF) grows linearly. Since a PDF should have an area equal to 1 and the maximum radius is 1, we have

So we know how the desired density of our random values should look like. Now: How do we generate such a random value when all we have is a uniform random value between 0 and 1?

We use a trick called inverse transform sampling

1. From the PDF, create the cumulative distribution function (CDF)
2. Mirror this along y = x
3. Apply the resulting function to a uniform value between 0 and 1.

Sounds complicated? Let me insert a blockquote with a little side track that conveys the intuition:

Suppose we want to generate a random point with the following distribution:

                

That is

• 1/5 of the points uniformly between 1 and 2, and
• 4/5 of the points uniformly between 2 and 3.

The CDF is, as the name suggests, the cumulative version of the PDF. Intuitively: While PDF(x) describes the number of random values at x, CDF(x) describes the number of random values less than x.

In this case the CDF would look like:

                

To see how this is useful, imagine that we shoot bullets from left to right at uniformly distributed heights. As the bullets hit the line, they drop down to the ground:

                

See how the density of the bullets on the ground correspond to our desired distribution! We're almost there!

The problem is that for this function, the y axis is the output and the x axis is the input. We can only "shoot bullets from the ground straight up"! We need the inverse function!

This is why we mirror the whole thing; x becomes y and y becomes x:

                

We call this CDF^-1. To get values according to the desired distribution, we use CDF^-1(random()).

…so, back to generating random radius values where our PDF equals 2x.

Step 1: Create the CDF:

Since we're working with reals, the CDF is expressed as the integral of the PDF.

CDF(x) = ? 2x = x²

Step 2: Mirror the CDF along y = x:

Mathematically this boils down to swapping x and y and solving for y:

CDF:     y = x²
Swap:   x = y²
Solve:   y = √x
CDF^-1:  y = √x

Step 3: Apply the resulting function to a uniform value between 0 and 1

CDF^-1(random()) = √random()

Which is what we set out to derive :-)

From the javadoc

@param  the sole object to be stored in the returned list.
@return an immutable list containing only the specified object.

example

import java.util.*;

public class HelloWorld {
    public static void main(String args[]) {
        // create an array of string objs
        String initList[] = { "One", "Two", "Four", "One",};

        // create one list
        List list = new ArrayList(Arrays.asList(initList));

        System.out.println("List value before: "+list);

        // create singleton list
        list = Collections.singletonList("OnlyOneElement");
        list.add("five"); //throws UnsupportedOperationException
        System.out.println("List value after: "+list);
    }
}

Use it when code expects a read-only list, but you only want to pass one element in it. singletonList is (thread-)safe and fast.

new_dict = {x: v for x, v in mydict.items() if x in mykeys}

One way is to use ANSI escape sequences:

import sys
import time
for i in range(10):
    print("Loading" + "." * i)
    sys.stdout.write("\033[F") # Cursor up one line
    time.sleep(1)

Also sometimes useful (for example if you print something shorter than before):

sys.stdout.write("\033[K") # Clear to the end of line

In jQuery I mostly use:

$("#element").trigger("change");

GET (multiple parameters):

curl -X  GET "http://localhost:3000/action?result1=gh&result2=ghk"

or

curl --request  GET "http://localhost:3000/action?result1=gh&result2=ghk"

or

curl  "http://localhost:3000/action?result1=gh&result2=ghk"

or

curl -i -H "Application/json" -H "Content-type: application/json"  "http://localhost:3000/action?result1=gh&result2=ghk"

Go to File > Sync Project with Gradles Files.

One could use the queryParam method, passing it parameter name and an array of values:

    public WebTarget queryParam(String name, Object... values);

Example (jersey-client 2.23.2):

    WebTarget target = ClientBuilder.newClient().target(URI.create("http://localhost"));
    target.path("path")
            .queryParam("param_name", Arrays.asList("paramVal1", "paramVal2").toArray())
            .request().get();

This will issue request to following URL:

    http://localhost/path?param_name=paramVal1&param_name=paramVal2

Edit: this information is for visualvm specifically, not for any other java app

As mentioned by others, you need to modify the visualvm.conf

For the latest version of JvisualVM 1.3.6 on Mac, the install directories have changed.

It is currently in /Applications/VisualVM.app/Contents/Resources/visualvm/etc/visualvm.conf.

However this may depend on where you have installed VisualVM. The easiest way to find where your VisualVM is to start it, and then look at the process using:

ps -ef | grep VisualVM

You will see something like:

... -Dnetbeans.dirs=/Applications/VisualVM.app/Contents/Resources/visualvm/visualvm...

You want to take the netbeans.dir property and look up a directory and you will find the etc folder.

Uncomment this line in the visualvm.conf and change the path to the jdk

visualvm_jdkhome="/path/to/jdk"

Additionally, if you are having slowness with your visualvm and you have a lot of memory, I would suggest greatly increasing the amount of memory available and running it in server mode:

visualvm_default_options="-J-XX:MaxPermSize=96m -J-Xmx2048m -J-Xms2048m -J-server -J-XX:+UseCompressedOops -J-XX:+UseConcMarkSweepGC -J-XX:+UseParNewGC -J-XX:NewRatio=2 -J-Dnetbeans.accept_license_class=com.sun.tools.visualvm.modules.startup.AcceptLicense -J-Dsun.jvmstat.perdata.syncWaitMs=10000 -J-Dsun.java2d.noddraw=true -J-Dsun.java2d.d3d=false"

Write editTextBackground.xml in drawable folder in resources

<shape xmlns:android="http://schemas.android.com/apk/res/android">
    <stroke
        android:width="1dp"
        android:color="@color/borderColor" />
</shape>

don't forget to declare color in resources named borderColor.

and assign this background to the EditText in xml background attribute

<EditText
    android:id="@+id/text"
    android:background="@drawable/editTextBackground"
    />

and it'll set border to EditText.

UPDATE

You can change border of edit text without drawable by using style attribute

style="@style/Widget.AppCompat.EditText"

for more details visit customize edit text

For completeness, if you wanted to use replaceFirst, try this:

public static String cap1stChar(String userIdea)
{
  String betterIdea = userIdea;
  if (userIdea.length() > 0)
  {
    String first = userIdea.substring(0,1);
    betterIdea = userIdea.replaceFirst(first, first.toUpperCase());
  }
  return betterIdea;
}//end cap1stChar

I wanted to share this because I spent a long time searching for an easy way to implement this in a java program I'm working on. This doesn't quite give the output you're looking for but its close. The function in mysql called GROUP_CONCAT() worked really well for specifying how many results to return in each group. Using LIMIT or any of the other fancy ways of trying to do this with COUNT didn't work for me. So if you're willing to accept a modified output, its a great solution. Lets say I have a table called 'student' with student ids, their gender, and gpa. Lets say I want to top 5 gpas for each gender. Then I can write the query like this

SELECT sex, SUBSTRING_INDEX(GROUP_CONCAT(cast(gpa AS char ) ORDER BY gpa desc), ',',5) 
AS subcategories FROM student GROUP BY sex;

Note that the parameter '5' tells it how many entries to concatenate into each row

And the output would look something like

+--------+----------------+
| Male   | 4,4,4,4,3.9    |
| Female | 4,4,3.9,3.9,3.8|
+--------+----------------+

You can also change the ORDER BY variable and order them a different way. So if I had the student's age I could replace the 'gpa desc' with 'age desc' and it will work! You can also add variables to the group by statement to get more columns in the output. So this is just a way I found that is pretty flexible and works good if you are ok with just listing results.

It is what it says, you just cannot instantiate an abstract class. You need to implement it first, then instantiate that class.

IUser user = new User();

The default IsSelected trigger changes 3 properties, Background, Foreground & BorderBrush. If you want to change the border as well as the background, just include this in your style trigger.

<Style TargetType="{x:Type dg:DataGridCell}">
    <Style.Triggers>
        <Trigger Property="dg:DataGridCell.IsSelected" Value="True">
            <Setter Property="Background" Value="#CCDAFF" />
            <Setter Property="BorderBrush" Value="Black" />
        </Trigger>
    </Style.Triggers>
</Style>

The date time you're passing is not a iso local date time format.

Change to

@Column(name = "start_date")
@DateTimeFormat(iso = DateTimeFormatter.ISO_LOCAL_DATE_TIME)
@JsonFormat(pattern = "YYYY-MM-dd HH:mm")
private LocalDateTime startDate;

and pass date string in the format '2011-12-03T10:15:30'.

But if you still want to pass your custom format, use just have to specify the right formatter.

Change to

@Column(name = "start_date")
@DateTimeFormat(iso = DateTimeFormatter.ofPattern("yyyy-MM-dd HH:mm"))
@JsonFormat(pattern = "YYYY-MM-dd HH:mm")
private LocalDateTime startDate;

I think your problem is the @DateTimeFormat has no effect at all. As the jackson is doing the deseralization and it doesnt know anything about spring annotation and I dont see spring scanning this annotation in the deserialization context.

Alternatively, you can try setting the formatter while registering the java time module.

LocalDateTimeDeserializer localDateTimeDeserializer = new LocalDateTimeDeserializer(DateTimeFormatter.ofPattern("yyyy-MM-dd HH:mm"));
module.addDeserializer(LocalDateTime.class, localDateTimeDeserializer);

Here is the test case with the deseralizer which works fine. May be try to get rid of that DateTimeFormat annotation altogether.

@RunWith(JUnit4.class)
public class JacksonLocalDateTimeTest {

    private ObjectMapper objectMapper;

    @Before
    public void init() {
        JavaTimeModule module = new JavaTimeModule();
        LocalDateTimeDeserializer localDateTimeDeserializer =  new LocalDateTimeDeserializer(DateTimeFormatter.ofPattern("yyyy-MM-dd HH:mm"));
        module.addDeserializer(LocalDateTime.class, localDateTimeDeserializer);
        objectMapper = Jackson2ObjectMapperBuilder.json()

    public void test() throws IOException {

Put from before where, and order_by on last:

$this->db->select('*');
$this->db->from('courses');
$this->db->where('tennant_id',$tennant_id);
$this->db->order_by("UPPER(course_name)","desc");

Or try BINARY:

ORDER BY BINARY course_name DESC;

You should add manually on codeigniter for binary sorting.

And set "course_name" character column.

If sorting is used on a character type column, normally the sort is conducted in a case-insensitive fashion.

What type of structure data in courses table?

If you frustrated you can put into array and return using PHP:

Use natcasesort for order in "natural order": (Reference: http://php.net/manual/en/function.natcasesort.php)

Your array from database as example: $array_db = $result_from_db:

$final_result = natcasesort($array_db);

print_r($final_result);

Show Processlist fetches the information from another table. Here is how you can pull the data and look at 'INFO' column which contains the whole query :

select * from INFORMATION_SCHEMA.PROCESSLIST where db = 'somedb';

You can add any condition or ignore based on your requirement.

The output of the query is resulted as :

+-------+------+-----------------+--------+---------+------+-----------+----------------------------------------------------------+
| ID    | USER | HOST            | DB     | COMMAND | TIME | STATE     | INFO                                                     |
+-------+------+-----------------+--------+---------+------+-----------+----------------------------------------------------------+
|     5 | ssss | localhost:41060 | somedb | Sleep   |    3 |           | NULL                                                     |
| 58169 | root | localhost       | somedb | Query   |    0 | executing | select * from sometable where tblColumnName = 'someName' |

settings.py:

DEBUG = False
TEMPLATE_DEBUG = DEBUG
ALLOWED_HOSTS = ['localhost']  #provide your host name

and just add your 404.html and 500.html pages in templates folder. remove 404.html and 500.html from templates in polls app.

--> is not an operator. It is in fact two separate operators, -- and >.

The conditional's code decrements x, while returning x's original (not decremented) value, and then compares the original value with 0 using the > operator.

To better understand, the statement could be written as follows:

while( (x--) > 0 )

Concatenate two std::vector-s with for loop in one std::vector.

    std::vector <int> v1 {1, 2, 3}; //declare vector1
    std::vector <int> v2 {4, 5}; //declare vector2
    std::vector <int> suma; //declare vector suma

    for(int i = 0; i < v1.size(); i++) //for loop 1
    {
         suma.push_back(v1[i]);
    }

    for(int i = 0; i< v2.size(); i++) //for loop 2
    {
         suma.push_back(v2[i]);
    }

    for(int i = 0; i < suma.size(); i++) //for loop 3-output
    {
         std::cout << suma[i];
    }

More compact version working with spaces and newlines in the file name:

find . -iname '*.txt' -exec sh -c 'echo "{}" ; ls -l "{}"' \;

Old question, but thought I'd share my solution anyway. Pretty simple.

dicta_set = set(dicta.items()) # creates a set of tuples (k/v pairs)
dictb_set = set(dictb.items())
setdiff = dictb_set.difference(dicta_set) # any set method you want for comparisons
for k, v in setdiff: # unpack the tuples for processing
    print(f"k/v differences = {k}: {v}")

This code creates two sets of tuples representing the k/v pairs. It then uses a set method of your choosing to compare the tuples. Lastly, it unpacks the tuples (k/v pairs) for processing.

The reason behind getting this Error Code : 3417 may be as follows:

• One cause may be due to the Network account for the Data folder in Program files.
• The other reason may be because of some Windows settings changed somehow.

Example: If for some reasons you have moved this folder (Program Files\Microsoft SQL Server\MSSQL11.MSSQLSERVER\MSSQL) to another location then returned it to the same location. So, though it was returned to the same location the server may stop working and show error code 3417 when trying to start it again.

How To Fix SQL Error 3417

• Go to "C:Program Files Microsoft SQLServerMSSQL.1MSSqLData"
• Security/Permission settings
• Network Service Account
• Add a Network Service account
• Then again check all

As stated here, you can try this third party tool as well.

Your if statement is setting the value. You want to compare it by doing this

if ($("#type").val() == "item1") {
 ...
}

daLizard is right though. You want an event handler. document.ready runs only once, when the page DOM is ready to be used.

DO NOT USE THE 4th solution from top if you are using ag-grid. It will fix the issue for aligning the element in middle but it might break the thing in ag-grid (for me i was not able to select checkbox after some row). Problem is not with the solution or ag-grid but somehow the combination is not good.

DO NOT USE THIS SOLUTION FOR AG-GRID

li a {
    width: 300px;
    height: 100px;
    margin: auto 0;
    display: inline-block;
    vertical-align: middle;
    background: red;  
}

li a:after {
    content:"";
    display: inline-block;
    width: 1px solid transparent;
    height: 100%;
    vertical-align: middle;
}

.center {
  margin: auto;
  margin-top: 15vh;
}

Should do the trick

If you need to remove text inside nested parentheses, too, then:

        var prevStr;
        do {
            prevStr = str;
            str = str.replace(/\([^\)\(]*\)/, "");
        } while (prevStr != str);

Albeit from the useless _T and incorrectly spelled histories. If you are using SQL*Plus, it does not accept create table statements with empty new lines between create table <name> ( and column definitions.

When you're running npm install in the project's root, it installs all of the npm dependencies into the project's node_modules directory.

If you take a look at the project's node_modules directory, you should see a directory called http-server, which holds the http-server package, and a .bin folder, which holds the executable binaries from the installed dependencies. The .bin directory should have the http-server binary (or a link to it).

So in your case, you should be able to start the http-server by running the following from your project's root directory (instead of npm start):

./node_modules/.bin/http-server -a localhost -p 8000 -c-1

This should have the same effect as running npm start.

If you're running a Bash shell, you can simplify this by adding the ./node_modules/.bin folder to your $PATH environment variable:

export PATH=./node_modules/.bin:$PATH

This will put this folder on your path, and you should be able to simply run

http-server -a localhost -p 8000 -c-1

The current directory is a system-level feature; it returns the directory that the server was launched from. It has nothing to do with the website.

You want HttpRuntime.AppDomainAppPath.

If you're in an HTTP request, you can also call Server.MapPath("~/Whatever").

A $ right before single quotation marks '...\n...' as follows, however double quotation marks doesn't work.

$ echo $'Hello\nWorld'
Hello
World
$ echo $"Hello\nWorld"
Hello\nWorld

You could do:

brew reinstall php55-imagick

Where php55 is your PHP version.

I use SQLite Database Browser for SQLite3 currently and it's pretty useful. Works across Windows/OS X/Linux and is lightweight and fast. Slightly unstable with executing SQL on the DB if it's incorrectly formatted.

Edit: I have recently discovered SQLite Manager, a plugin for Firefox. Obviously you need to run Firefox, but you can close all windows and just run it "standalone". It's very feature complete, amazingly stable and it remembers your databases! It has tonnes of features so I've moved away from SQLite Database Browser as the instability and lack of features is too much to bear.

        $(document).ready(function(){

            $("body").css("-o-user-select","none");
            $("body").css("user-select","none");
        });

Try using Select instead of Print

DECLARE @Test AS DATETIME 

SET @Test = '2011-02-15'

Select @Test

I'm not familiar with Mac OS Dashcode Widgets, but if they let you use JavaScript libraries and support XMLHttpRequests, I'd use jQuery and do something like this:

var page_content;
$.get( "somepage.php", function(data){
    page_content = data;
});

INSERT
INTO    Employee 
        (emp_id, emp_name, emp_address, emp_state, emp_position, emp_manager)
SELECT  '001', 'John Doe', '1 River Walk, Green Street', state_id, position_id, manager_id
FROM    dual
JOIN    state s
ON      s.state_name = 'New York'
JOIN    positions p
ON      p.position_name = 'Sales Executive'
JOIN    manager m
ON      m.manager_name = 'Barry Green'

Note that but a single spelling mistake (or an extra space) will result in a non-match and nothing will be inserted.

Files related for deployment (and others temporary items) are created in standalone/tmp/vfs (Virtual File System). You may add a policy at startup for evicting temporary files :

-Djboss.vfs.cache=org.jboss.virtual.plugins.cache.IterableTimedVFSCache 
-Djboss.vfs.cache.TimedPolicyCaching.lifetime=1440

append is a jQuery method to append some content or HTML to an element.

$('#example').append('Some text or HTML');

appendChild is a pure DOM method for adding a child element.

document.getElementById('example').appendChild(newElement);

Toast duration can be hacked using a thread that runs the toast exclusively. This works (runs the toast for 10 secs, modify sleep and ctr to your liking):

final Toast toast = Toast.makeText(this, "Your Message", Toast.LENGTH_LONG);

Thread t = new Thread(){
    public void run(){
          int ctr = 0;
          try{
               while( ctr<10 ){
                    toast.show();
                    sleep(1000);
                    ctr++;
               }
          } catch (Exception e) {
               Log.e("Error", "", e);
          }
     }
 };
 t.start();

You can get this issue if Apple update their terms. Simply log into your dev account and accept any updated terms and you should be good (you will need to goto Xcode -> project->signing and capabilities and retry the certificate check. This should get you going if terms are the issue.

If you are using an executable,

• just run the executable (for example: "en_sql_server_2012_express_edition_with_advanced_services_x64.exe")
• Navigate to the "options" tab
• Copy the "Installation Media Root Directory" (should look something like the below snipping)
• Paste it into the open "Browse for SQL server Installation Media" window

Save yourself the hastle of renaming and unzipping etc.!

Well, the first question is easy. There are many ens (Englishes) but (mostly) only one US English. One would guess there are en-CN, en-GB, en-AU. Guess there might even be Austrian English but that's more yes you can than yes there is.

This not only works with cmake, but also with ./configure and make:

./configure CC=/usr/local/bin/gcc CXX=/usr/local/bin/g++

Which is resulting in:

checking for gcc... /usr/local/bin/gcc
checking whether the C compiler works... yes

echo "this is the body" | mail -s "this is the subject" "to@address"

Messing around with environment variables or hard-coded parent folder offsets is never a good idea when there is a API to get the info you want, call SHGetSpecialFolderPath(...,CSIDL_PROFILE,...)

SQLAlchemy is very, very powerful. However it is not thread safe make sure you keep that in mind when working with cherrypy in thread-pool mode.

you should have either (or both):

1. a paddding != 0 on body
2. a margin !=0 on #header

try

html, #header {
    margin: 0 !important;
    padding: 0 !important;
}

The margin is the "space" outside the box, the padding is the "space" inside the box (between the border and the content). The !important prevent overriding of property by latter rules.

What you really want to do is use an XML parser and append the new elements with the API provided.

Then simply overwrite the file.

The easiest to use would probably be a DOM parser like the one below:

http://docs.python.org/library/xml.dom.minidom.html

In C++11, you can use std::any_of instead.

An example to find if there is any zero in the array:

std::array<int,3> foo = {0,1,-1};
if ( std::any_of(foo.begin(), foo.end(), [](int i){return i==0;}) )
std::cout << "zero found...";

Here is a very good explanation of why using Laravel's Database Seeder is preferable to using Migrations: https://web.archive.org/web/20171018135835/http://laravelbook.com/laravel-database-seeding/

Although, following the instructions on the official documentation is a much better idea because the implementation described at the above link doesn't seem to work and is incomplete. http://laravel.com/docs/migrations#database-seeding

This is an "old school solution", when MERGE command does not work (I think before version 10).

UPDATE TARGET_TABLE T 
SET (T.VAL1, T.VAL2 ) =  
(SELECT S.VAL1, S.VAL2
 FROM SOURCE_TABLE S

WHERE EXISTS 
(SELECT 1  
 FROM SOURCE_TABLE S 
 WHERE T.KEY1 = S.KEY1 AND T.KEY2 = S.KEY2 
   AND (T.VAL1 <> S.VAL1 OR T.VAL2 <> S.VAL2));

I am finally able to solve this error after researching some things I thought is causing the error for 24 errors. I visited all the pages across the web. And I am happy to say that I have found the solution. If you are using NGINX, then set gzip to off and add proxy_max_temp_file_size 0; in the server block like I have shown below.

 server {
  ...
  ...
  gzip off;
  proxy_max_temp_file_size 0;
  location / {
    proxy_pass http://127.0.0.1:3000/;
  ....

Why? Because what actually happening was all the contents were being compressed twice and we don't want that, right?!

This happens because of one the following reasons:

1. You do not have the SDK API installed (this was my problem)
2. Your project/Android Studio doesn’t know where the needed files are
3. Your project references an outdated compile version that does not support AppCompatActivity
4. There is a typo

Possible solutions:

1. Check your .gradle file to make sure you’re not referencing an outdated version. AppCompatActivity was added in version 25.1.0 and belongs to Maven artifact com.android.support:appcompat-v7:28.0.0-alpha1, so do not use any version earlier than this. In your build.gradle (Module: app) file you should have the dependency listed:

   dependencies { compile 'com.android.support:appcompat-v7:25.1.0' }

   You may be using a different version, but just make sure you have listed the dependency.

2. Open the SDK manager and download every API 7 or newer. If you were missing the needed API it will fix that issue, and downloading all the newer API’s can save you some hassle later on as well.

3. Check for typos in your import statement. Make sure it doesn’t say “AppCompactActivity” instead of “AppCompatActivity”.
4. Resync your project (File >Sync project with Gradle files)
5. Rebuild your project (Build >rebuild)
6. Clean your project (Build >clean project)
7. Close and restart Android Studio
8. Update Android Studio
9. Regenerate your libraries folder – In Android Studio, view your files in project view. Find the folder YourProjectName >.idea >libraries. Rename the folder to “libraries_delete_me”. Close and reopen Android Studio. Open your project again and the libraries folder should be regenerated with all of the files; you can now delete the “libraries_delete_me” folder.

Just do (int)myLongValue. It'll do exactly what you want (discarding MSBs and taking LSBs) in unchecked context (which is the compiler default). It'll throw OverflowException in checked context if the value doesn't fit in an int:

int myIntValue = unchecked((int)myLongValue);

Unless you want to go the VBA route to work out the Tab name, the Excel formula is fairly ugly based upon Mid functions, etc. But both these methods can be found here if you want to go that way.

Rather, the way I would do it is:

1) Make one cell on your sheet named, for example, Reference_Sheet and put in that cell the value "Jan Item" for example.

2) Now, use the Indirect function like:

=INDIRECT(Reference_Sheet&"!J3") 

3) Now, for each month's sheet, you just have to change that one Reference_Sheet cell.

Hope this gives you what you're looking for!

char cString1[]

This is an array, i.e. a pointer to the first element of a range of elements of the same data type. Note you're not passing the array by-value but by-pointer.

char strToLower(...)

However, this returns a char. So your assignment

cString1 = strToLower(cString1);

has different types on each side of the assignment operator .. you're actually assigning a 'char' (sort of integer) to an array, which resolves to a simple pointer. Due to C++'s implicit conversion rules this works, but the result is rubbish and further access to the array causes undefined behaviour.

The solution is to make strToLower return char*.

Go to Start

Type regsvr32 hhctrl.ocx

You should get a success message like:

" DllRegisterServer in hhctrl.ocx succeeded "

Now try to open your CHM file again.

You can compress the bitmap as an byte's array and then uncompress it in another activity, like this.

Compress!!

        ByteArrayOutputStream stream = new ByteArrayOutputStream();
        bmp.compress(Bitmap.CompressFormat.PNG, 100, stream);
        byte[] bytes = stream.toByteArray(); 
        setresult.putExtra("BMP",bytes);

Uncompress!!

        byte[] bytes = data.getByteArrayExtra("BMP");
        Bitmap bmp = BitmapFactory.decodeByteArray(bytes, 0, bytes.length);

Just define your action method like this

public string ThemePath()

and simply return the string itself.

If not HTML, then UTF-8 is not recommended. koi8-r and windows-1251 only without problems. So use html mail.

$headers['Content-Type']='text/html; charset=UTF-8';
$body='<html><head><meta charset="UTF-8"><title>ESP Notufy - ESP ?????????</title></head><body>'.$text.'</body></html>';


$mail_object=& Mail::factory('smtp',
    array ('host' => $host,
        'auth' => true,
        'username' => $username,
        'password' => $password));
$mail_object->send($recipents, $headers, $body);
}

\t is a tab character. Use a raw string instead:

test_file=open(r'c:\Python27\test.txt','r')

or double the slashes:

test_file=open('c:\\Python27\\test.txt','r')

or use forward slashes instead:

test_file=open('c:/Python27/test.txt','r')

Try this

HttpServletResponse response;       
response.sendRedirect(".../webpage.xhtml");

Because when you do shift() on an array, it changes the length of the array. So the for loop will be messed up. You can loop through from end to front to avoid this problem.

Btw, I assume you try to remove the element at the position i rather than the first element of the array. ($scope.items.shift(); in your code will remove the first element of the array)

for(var i = $scope.items.length - 1; i >= 0; i--){
    if($scope.items[i].name == 'ted'){
        $scope.items.splice(i,1);
    }
}

This problem would be caused by your application missing a reference to an external dll that you are trying to use code from. Usually Visual Studio should give you an idea about which objects that it doesn't know what to do with so that should be a step in the right direction.

You need to look in the solution explorer and right click on project references and then go to add -> and look up the one you need. It's most likely the System.Configuration assembly as most people have pointed out here while should be under the Framework option in the references window. That should resolve your issue.

The structure of your menu code is the issue:

cin >> choice;   // new line character is left in the stream

 switch ( ... ) {
     // We enter the handlers, '\n' still in the stream
 }

cin.ignore();   // Put this right after cin >> choice, before you go on
                // getting input with getline.

It's not pretty, but the way I resign the firstResponder when I don't know what that the responder is:

Create an UITextField, either in IB or programmatically. Make it Hidden. Link it up to your code if you made it in IB.

Then, when you want to dismiss the keyboard, you switch the responder to the invisible text field, and immediately resign it:

    [self.invisibleField becomeFirstResponder];
    [self.invisibleField resignFirstResponder];

The application/x-www-form-urlencoded Content-type header is not needed. Unless the request handler expects the parameters coming from request body. Try it out:

curl -X DELETE "http://localhost:5000/locations?id=3"

or

curl -X GET "http://localhost:5000/locations?id=3"

From my understanding, both terms have roots in philosophy, there are declarative and imperative kinds of knowledge. Declarative knowledge are assertions of truth, statements of fact like math axioms. It tells you something. Imperative, or procedural knowledge, tells you step by step how to arrive at something. That's what the definition of an algorithm essentially is. If you would, compare a computer programming language with the English language. Declarative sentences state something. A boring example, but here's a declarative way of displaying whether two numbers are equal to each other, in Java:

public static void main(String[] args)
{
    System.out.print("4 = 4.");
}

Imperative sentences in English, on the other hand, give a command or make some sort of request. Imperative programming, then, is just a list of commands (do this, do that). Here's an imperative way of displaying whether two numbers are equal to each other or not while accepting user input, in Java:

private static Scanner input;    

public static void main(String[] args) 
{
    input = new Scanner(System.in);
    System.out.println();
    System.out.print("Enter an integer value for x: ");
    int x = input.nextInt();
    System.out.print("Enter an integer value for y: ");        
    int y = input.nextInt();

    System.out.println();
    System.out.printf("%d == %d? %s\n", x, y, x == y);
}

Essentially, declarative knowledge skips over certain elements to form a layer of abstraction over those elements. Declarative programming does the same.

Here's how I did it... No need for try-catch block... The best solution is always the simplest... Enjoy!

$content = @file_get_contents("http://www.google.com");
if (strpos($http_response_header[0], "200")) { 
   echo "SUCCESS";
} else { 
   echo "FAILED";
} 

The question mentions Windows, and the accepted answer also works for Ubuntu, but for those who found this question coming from a Redhat flavor of Linux, this did the trick:

sudo yum install -y python-setuptools

You should enable the unicode strings feature, and this is the default if you use v5.14;

You should not really use unicode identifiers esp. for foreign code via utf8 as they are insecure in perl5, only cperl got that right. See e.g. http://perl11.org/blog/unicode-identifiers.html

Regarding utf8 for your filehandles/streams: You need decide by yourself the encoding of your external data. A library cannot know that, and since not even libc supports utf8, proper utf8 data is rare. There's more wtf8, the windows aberration of utf8 around.

BTW: Moose is not really "Modern Perl", they just hijacked the name. Moose is perfect Larry Wall-style postmodern perl mixed with Bjarne Stroustrup-style everything goes, with an eclectic aberration of proper perl6 syntax, e.g. using strings for variable names, horrible fields syntax, and a very immature naive implementation which is 10x slower than a proper implementation. cperl and perl6 are the true modern perls, where form follows function, and the implementation is reduced and optimized.

i solved my problem using port 25 and Following prop

mailSender.javaMailProperties.putAll([
                "mail.smtp.auth": "true",
                "mail.smtp.starttls.enable": "false",
                "mail.smtp.ssl.enable": "false",
                "mail.smtp.socketFactory.fallback": "true",
        ]);

Run command rndc querylog on or add querylog yes; to options{}; section in named.conf to activate that channel.

Also make sure you’re checking correct directory if your bind is chrooted.

This depends a lot on what you mean by "revert".

Temporarily switch to a different commit

If you want to temporarily go back to it, fool around, then come back to where you are, all you have to do is check out the desired commit:

# This will detach your HEAD, that is, leave you with no branch checked out:
git checkout 0d1d7fc32

Or if you want to make commits while you're there, go ahead and make a new branch while you're at it:

git checkout -b old-state 0d1d7fc32

To go back to where you were, just check out the branch you were on again. (If you've made changes, as always when switching branches, you'll have to deal with them as appropriate. You could reset to throw them away; you could stash, checkout, stash pop to take them with you; you could commit them to a branch there if you want a branch there.)

Hard delete unpublished commits

If, on the other hand, you want to really get rid of everything you've done since then, there are two possibilities. One, if you haven't published any of these commits, simply reset:

# This will destroy any local modifications.
# Don't do it if you have uncommitted work you want to keep.
git reset --hard 0d1d7fc32

# Alternatively, if there's work to keep:
git stash
git reset --hard 0d1d7fc32
git stash pop
# This saves the modifications, then reapplies that patch after resetting.
# You could get merge conflicts, if you've modified things which were
# changed since the commit you reset to.

If you mess up, you've already thrown away your local changes, but you can at least get back to where you were before by resetting again.

Undo published commits with new commits

On the other hand, if you've published the work, you probably don't want to reset the branch, since that's effectively rewriting history. In that case, you could indeed revert the commits. With Git, revert has a very specific meaning: create a commit with the reverse patch to cancel it out. This way you don't rewrite any history.

# This will create three separate revert commits:
git revert a867b4af 25eee4ca 0766c053

# It also takes ranges. This will revert the last two commits:
git revert HEAD~2..HEAD

#Similarly, you can revert a range of commits using commit hashes (non inclusive of first hash):
git revert 0d1d7fc..a867b4a

# Reverting a merge commit
git revert -m 1 <merge_commit_sha>

# To get just one, you could use `rebase -i` to squash them afterwards
# Or, you could do it manually (be sure to do this at top level of the repo)
# get your index and work tree into the desired state, without changing HEAD:
git checkout 0d1d7fc32 .

# Then commit. Be sure and write a good message describing what you just did
git commit

The git-revert manpage actually covers a lot of this in its description. Another useful link is this git-scm.com section discussing git-revert.

If you decide you didn't want to revert after all, you can revert the revert (as described here) or reset back to before the revert (see the previous section).

You may also find this answer helpful in this case:
How can I move HEAD back to a previous location? (Detached head) & Undo commits

If you use Handler (I see you do and hopefully you created its instance on the UI thread), then don't use runOnUiThread() inside of your runnable. runOnUiThread() is used when you do smth from a non-UI thread, however Handler will already execute your runnable on UI thread.

Try to do smth like this:

private Handler mHandler = new Handler();
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.gameone);
    res = getResources();
    // pB.setProgressDrawable(getResources().getDrawable(R.drawable.green)); **//Works**
    mHandler.postDelayed(runnable, 1);
}

private Runnable runnable = new Runnable() {
    public void run() {
        pB.setProgressDrawable(getResources().getDrawable(R.drawable.green));
        pB.invalidate(); // maybe this will even not needed - try to comment out
    }
};

I think this is what you are looking for? If you are looking to add a blur effect to a div element, you can do this directly through CSS Filters-- See fiddle: http://jsfiddle.net/ayhj9vb0/

 div {
  -webkit-filter: blur(5px);
  -moz-filter: blur(5px);
  -o-filter: blur(5px);
  -ms-filter: blur(5px);
  filter: blur(5px);
  width: 100px;
  height: 100px;
  background-color: #ccc;

}

Yes, there is a way to write to the event log you are looking for. You don't need to create a new source, just simply use the existent one, which often has the same name as the EventLog's name and also, in some cases like the event log Application, can be accessible without administrative privileges*.

*Other cases, where you cannot access it directly, are the Security EventLog, for example, which is only accessed by the operating system.

I used this code to write directly to the event log Application:

using (EventLog eventLog = new EventLog("Application")) 
{
    eventLog.Source = "Application"; 
    eventLog.WriteEntry("Log message example", EventLogEntryType.Information, 101, 1); 
}

As you can see, the EventLog source is the same as the EventLog's name. The reason of this can be found in Event Sources @ Windows Dev Center (I bolded the part which refers to source name):

Each log in the Eventlog key contains subkeys called event sources. The event source is the name of the software that logs the event. It is often the name of the application or the name of a subcomponent of the application if the application is large. You can add a maximum of 16,384 event sources to the registry.

include() needs a full file path, relative to the file system's root directory.

This should work:

 include_once("C:/xampp/htdocs/PoliticalForum/headerSite.php");

Use this

jQuery("input.second").trigger("click");

condition ? truth : false;

If the condition is true then evaluate the first expression. If the condition is false, evaluate the second expression.

It is called the Conditional Operator and it is a type of Ternary Operation.

If you are looking for the last row of a column, use:

Sub SelectFirstColumn()
   SelectEntireColumn (1)
End Sub

Sub SelectSecondColumn()
    SelectEntireColumn (2)
End Sub

Sub SelectEntireColumn(columnNumber)
    Dim LastRow
    Sheets("sheet1").Select
    LastRow = ActiveSheet.Columns(columnNumber).SpecialCells(xlLastCell).Row

    ActiveSheet.Range(Cells(1, columnNumber), Cells(LastRow, columnNumber)).Select
End Sub

Other commands you will need to get familiar with are copy and paste commands:

Sub CopyOneToTwo()
    SelectEntireColumn (1)
    Selection.Copy

    Sheets("sheet1").Select
    ActiveSheet.Range("B1").PasteSpecial Paste:=xlPasteValues
End Sub

Finally, you can reference worksheets in other workbooks by using the following syntax:

Dim book2
Set book2 = Workbooks.Open("C:\book2.xls")
book2.Worksheets("sheet1")

$value = "he doesn't work for me";

$new_value = str_replace("'", "''", "$value"); // it looks like  " ' "  , " ' ' " 

INSERT INTO exampleTbl (`column`) VALUES('$new_value')

For Swift with a UINavigationController:

override func viewWillDisappear(animated: Bool) {
    super.viewWillDisappear(animated)
    if self.navigationController?.topViewController != self {
        print("back button tapped")
    }
}

You can simply format your range as Text.

Also here is a nice article on the number formats and how you can program them.

Square brackets:

jsObj['key' + i] = 'example' + 1;

In JavaScript, all arrays are objects, but not all objects are arrays. The primary difference (and one that's pretty hard to mimic with straight JavaScript and plain objects) is that array instances maintain the length property so that it reflects one plus the numeric value of the property whose name is numeric and whose value, when converted to a number, is the largest of all such properties. That sounds really weird, but it just means that given an array instance, the properties with names like "0", "5", "207", and so on, are all treated specially in that their existence determines the value of length. And, on top of that, the value of length can be set to remove such properties. Setting the length of an array to 0 effectively removes all properties whose names look like whole numbers.

OK, so that's what makes an array special. All of that, however, has nothing at all to do with how the JavaScript [ ] operator works. That operator is an object property access mechanism which works on any object. It's important to note in that regard that numeric array property names are not special as far as simple property access goes. They're just strings that happen to look like numbers, but JavaScript object property names can be any sort of string you like.

Thus, the way the [ ] operator works in a for loop iterating through an array:

for (var i = 0; i < myArray.length; ++i) {
  var value = myArray[i]; // property access
  // ...
}

is really no different from the way [ ] works when accessing a property whose name is some computed string:

var value = jsObj["key" + i];

The [ ] operator there is doing precisely the same thing in both instances. The fact that in one case the object involved happens to be an array is unimportant, in other words.

When setting property values using [ ], the story is the same except for the special behavior around maintaining the length property. If you set a property with a numeric key on an array instance:

myArray[200] = 5;

then (assuming that "200" is the biggest numeric property name) the length property will be updated to 201 as a side-effect of the property assignment. If the same thing is done to a plain object, however:

myObj[200] = 5;

there's no such side-effect. The property called "200" of both the array and the object will be set to the value 5 in otherwise the exact same way.

One might think that because that length behavior is kind-of handy, you might as well make all objects instances of the Array constructor instead of plain objects. There's nothing directly wrong about that (though it can be confusing, especially for people familiar with some other languages, for some properties to be included in the length but not others). However, if you're working with JSON serialization (a fairly common thing), understand that array instances are serialized to JSON in a way that only involves the numerically-named properties. Other properties added to the array will never appear in the serialized JSON form. So for example:

var obj = [];
obj[0] = "hello world";
obj["something"] = 5000;

var objJSON = JSON.stringify(obj);

the value of "objJSON" will be a string containing just ["hello world"]; the "something" property will be lost.

ES2015:

If you're able to use ES6 JavaScript features, you can use Computed Property Names to handle this very easily:

var key = 'DYNAMIC_KEY',
    obj = {
        [key]: 'ES6!'
    };

console.log(obj);
// > { 'DYNAMIC_KEY': 'ES6!' }

Style the td and th instead

td, th {
    border: 1px solid black;
}

And also to make it so there is no spacing between cells use:

table {
    border-collapse: collapse;
}

(also note, you have border-style: none; which should be border-style: solid;)

See an example here: http://jsfiddle.net/KbjNr/

I got a simple fix to this by casting the lists into strings and performing string operations to get the proper print out of the matrix.

Creating the function

By creating a function, it saves you the trouble of writing the for loop every time you want to print out a matrix.

def print_matrix(matrix):
    for row in matrix:
        new_row = str(row)
        new_row = new_row.replace(',','')
        new_row = new_row.replace('[','')
        new_row = new_row.replace(']','')
        print(new_row)

Examples

Example of a 5x5 matrix with 0 as every entry:

>>> test_matrix = [[0] * 5 for i in range(5)]
>>> print_matrix(test_matrix)
0 0 0 0 0
0 0 0 0 0
0 0 0 0 0
0 0 0 0 0
0 0 0 0 0 

Example of a 2x3 matrix with 0 as every entry:

>>> test_matrix = [[0] * 3 for i in range(2)]
>>> print_matrix(test_matrix)
0 0 0
0 0 0

EDIT

If you want to make it print:

A A A A A
B B B B B
C C C C C
D D D D D 
E E E E E

I suggest you just change the way you enter your data into your lists within lists. In my method, each list within the larger list represents a line in the matrix, not columns.

You should use method array_push to add value or array to array exists

$stack = array("orange", "banana");
array_push($stack, "apple", "raspberry");
print_r($stack);

/** GENERATED OUTPUT
Array
(
    [0] => orange
    [1] => banana
    [2] => apple
    [3] => raspberry
)
*/

If you intend to use the default VB6 Collection, then the easiest you can do is:

col1.add array("first key", "first string"), "first key"
col1.add array("second key", "second string"), "second key"
col1.add array("third key", "third string"), "third key"

Then you can list all values:

Dim i As Variant

For Each i In col1
  Debug.Print i(1)
Next

Or all keys:

Dim i As Variant

For Each i In col1
  Debug.Print i(0)
Next

In RxJS 5+ you can do it like this

import { Observable } from "rxjs/Observable";
import { of } from "rxjs/observable/of";
import { delay } from "rxjs/operators";

fakeObservable = of('dummy').pipe(delay(5000));

In RxJS 6+

import { of } from "rxjs";
import { delay } from "rxjs/operators";

fakeObservable = of('dummy').pipe(delay(5000));

If you want to delay each emitted value try

from([1, 2, 3]).pipe(concatMap(item => of(item).pipe(delay(1000))));

public static <T> T ifNull(T toCheck, T ifNull) {
    if (toCheck == null) {
           return ifNull;
    }
    return toCheck;
}

You could always try the Synth look & feel. You provide an xml file that acts as a sort of stylesheet, along with any images you want to use. The code might look like this:

try {
    SynthLookAndFeel synth = new SynthLookAndFeel();
    Class aClass = MainFrame.class;
    InputStream stream = aClass.getResourceAsStream("\\default.xml");

    if (stream == null) {
        System.err.println("Missing configuration file");
        System.exit(-1);                
    }

    synth.load(stream, aClass);

    UIManager.setLookAndFeel(synth);
} catch (ParseException pe) {
    System.err.println("Bad configuration file");
    pe.printStackTrace();
    System.exit(-2);
} catch (UnsupportedLookAndFeelException ulfe) {
    System.err.println("Old JRE in use. Get a new one");
    System.exit(-3);
}

From there, go on and add your JButton like you normally would. The only change is that you use the setName(string) method to identify what the button should map to in the xml file.

The xml file might look like this:

<synth>
    <style id="button">
        <font name="DIALOG" size="12" style="BOLD"/>
        <state value="MOUSE_OVER">
            <imagePainter method="buttonBackground" path="dirt.png" sourceInsets="2 2 2 2"/>
            <insets top="2" botton="2" right="2" left="2"/>
        </state>
        <state value="ENABLED">
            <imagePainter method="buttonBackground" path="dirt.png" sourceInsets="2 2 2 2"/>
            <insets top="2" botton="2" right="2" left="2"/>
        </state>
    </style>
    <bind style="button" type="name" key="dirt"/>
</synth>

The bind element there specifies what to map to (in this example, it will apply that styling to any buttons whose name property has been set to "dirt").

And a couple of useful links:

http://javadesktop.org/articles/synth/

http://docs.oracle.com/javase/tutorial/uiswing/lookandfeel/synth.html

I just put this into a static class.

  const int WM_USER = 0x400;
  const int PBM_SETSTATE = WM_USER + 16;
  const int PBM_GETSTATE = WM_USER + 17;

  [DllImport("user32.dll", CharSet = CharSet.Auto, SetLastError = false)]
  static extern IntPtr SendMessage(IntPtr hWnd, uint Msg, IntPtr wParam, IntPtr lParam);

  public enum ProgressBarStateEnum : int
  {
   Normal = 1,
   Error = 2,
   Paused = 3,
  }

  public static ProgressBarStateEnum GetState(this ProgressBar pBar)
  {
   return (ProgressBarStateEnum)(int)SendMessage(pBar.Handle, PBM_GETSTATE, IntPtr.Zero, IntPtr.Zero);
  }

  public static void SetState(this ProgressBar pBar, ProgressBarStateEnum state)
  {
   SendMessage(pBar.Handle, PBM_SETSTATE, (IntPtr)state, IntPtr.Zero);
  } 

Hope it helps,

You can use console.log() in Firebug or Chrome to get a good object view here, like this:

$.getJSON('my.json', function(data) {
  console.log(data);
});

If you just want to view the string, look at the Resource view in Chrome or the Net view in Firebug to see the actual string response from the server (no need to convert it...you received it this way).

If you want to take that string and break it down for easy viewing, there's an excellent tool here: http://json.parser.online.fr/

i had to change my form's POST to a GET. i was just doing a demo post to an html page, on a test azure site. read this for info: http://support.microsoft.com/kb/942051

I would like to offer a minor improvement on the last loop answer given in the previous post (that post is correct and should still be accepted). The implicit assumption made when labeling the last example is that plt.label(LIST) puts label number X in LIST with the line corresponding to the Xth time plot was called. I have run into problems with this approach before. The recommended way to build legends and customize their labels per matplotlibs documentation ( http://matplotlib.org/users/legend_guide.html#adjusting-the-order-of-legend-item) is to have a warm feeling that the labels go along with the exact plots you think they do:

...
# Plot several different functions...
labels = []
plotHandles = []
for i in range(1, num_plots + 1):
    x, = plt.plot(some x vector, some y vector) #need the ',' per ** below
    plotHandles.append(x)
    labels.append(some label)
plt.legend(plotHandles, labels, 'upper left',ncol=1)

**: Matplotlib Legends not working

You can also keep adding strings to an existing string like so:

var myString = "Hello ";
myString += "World";
myString += "!";

the result would be -> Hello World!

SELECT * FROM ... WHERE name = 'someone' COLLATE NOCASE

If you don't know the row number, but do know some values then you can use subset

x <- structure(list(A = c(5,    3.5, 3.25, 4.25,  1.5 ), 
                    B = c(4.25, 4,   4,    4.5,   4.5 ),
                    C = c(4.5,  2.5, 4,    2.25,  3   )
               ),
               .Names    = c("A", "B", "C"),
               class     = "data.frame",
               row.names = c(NA, -5L)
     )

subset(x, A ==5 & B==4.25 & C==4.5)

As mentioned by @Sebastian the default solution should aim to use run(): https://docs.python.org/3/library/subprocess.html#subprocess.run

Here a convenient implementation (feel free to change the log class with print statements or what ever other logging functionality you are using):

import subprocess

def _run_command(command):
    log.debug("Command: {}".format(command))
    result = subprocess.run(command, shell=True, capture_output=True)
    if result.stderr:
        raise subprocess.CalledProcessError(
                returncode = result.returncode,
                cmd = result.args,
                stderr = result.stderr
                )
    if result.stdout:
        log.debug("Command Result: {}".format(result.stdout.decode('utf-8')))
    return result

And sample usage (code is unrelated, but I think it serves as example of how readable and easy to work with errors it is with this simple implementation):

try:
    # Unlock PIN Card
    _run_command(
        "sudo qmicli --device=/dev/cdc-wdm0 -p --uim-verify-pin=PIN1,{}"
        .format(pin)
    )

except subprocess.CalledProcessError as error:
    if "couldn't verify PIN" in error.stderr.decode("utf-8"):
        log.error(
                "SIM card could not be unlocked. "
                "Either the PIN is wrong or the card is not properly connected. "
                "Resetting module..."
                )
        _reset_4g_hat()
        return

JSFiddle: http://jsfiddle.net/YShs2/

It has already been explained that calling system.gc() may do nothing, and that any code that "needs" the garbage collector to run is broken.

However, the pragmatic reason that it is bad practice to call System.gc() is that it is inefficient. And in the worst case, it is horribly inefficient! Let me explain.

A typical GC algorithm identifies garbage by traversing all non-garbage objects in the heap, and inferring that any object not visited must be garbage. From this, we can model the total work of a garbage collection consists of one part that is proportional to the amount of live data, and another part that is proportional to the amount of garbage; i.e. work = (live * W1 + garbage * W2).

Now suppose that you do the following in a single-threaded application.

System.gc(); System.gc();

The first call will (we predict) do (live * W1 + garbage * W2) work, and get rid of the outstanding garbage.

The second call will do (live* W1 + 0 * W2) work and reclaim nothing. In other words we have done (live * W1) work and achieved absolutely nothing.

We can model the efficiency of the collector as the amount of work needed to collect a unit of garbage; i.e. efficiency = (live * W1 + garbage * W2) / garbage. So to make the GC as efficient as possible, we need to maximize the value of garbage when we run the GC; i.e. wait until the heap is full. (And also, make the heap as big as possible. But that is a separate topic.)

If the application does not interfere (by calling System.gc()), the GC will wait until the heap is full before running, resulting in efficient collection of garbage¹. But if the application forces the GC to run, the chances are that the heap won't be full, and the result will be that garbage is collected inefficiently. And the more often the application forces GC, the more inefficient the GC becomes.

Note: the above explanation glosses over the fact that a typical modern GC partitions the heap into "spaces", the GC may dynamically expand the heap, the application's working set of non-garbage objects may vary and so on. Even so, the same basic principal applies across the board to all true garbage collectors². It is inefficient to force the GC to run.

^{1 - This is how the "throughput" collector works. Concurrent collectors such as CMS and G1 use different criteria to decide when to start the garbage collector.}

^{2 - I'm also excluding memory managers that use reference counting exclusively, but no current Java implementation uses that approach ... for good reason.}

In addition, it's convenient to define variables referring to objects. For instance,

Sub CreateTable()
    Dim lo as ListObject
    Set lo = ActiveSheet.ListObjects.Add(xlSrcRange, Range("$B$1:$D$16"), , xlYes)
    lo.Name = "Table1"
    lo.TableStyle = "TableStyleLight2"
    ...
End Sub

You will probably find it advantageous at once.

I fear this might turn out to BE the long way round but could depend on how big your data set is – presumably more than four months for example.

Assuming your data is in ColumnA:C and has column labels in Row 1, also that Month is formatted mmm(this last for ease of sorting):

1. Sort the data by Name then Month
2. Enter in D2 =IF(AND(A2=A1,C2=C1),D1+1,1) (One way to deal with what is the tricky issue of multiple entries for the same person for the same month).
3. Create a pivot table from A1:D(last occupied row no.)
4. Say insert in F1.
5. Layout as in screenshot.

I’m hoping this would be adequate for your needs because pivot table should automatically update (provided range is appropriate) in response to additional data with refresh. If not (you hard taskmaster), continue but beware that the following steps would need to be repeated each time the source data changes.

5. Copy pivot table and Paste Special/Values to, say, L1.
6. Delete top row of copied range with shift cells up.
7. Insert new cell at L1 and shift down.
8. Key 'Name' into L1.
9. Filter copied range and for ColumnL, select Row Labels and numeric values.
10. Delete contents of L2:L(last selected cell)
11. Delete blank rows in copied range with shift cells up (may best via adding a column that counts all 12 months). Hopefully result should be as highlighted in yellow.

Happy to explain further/try again (I've not really tested this) if does not suit.

EDIT (To avoid second block of steps above and facilitate updating for source data changes)

.0. Before first step 2. add a blank row at the very top and move A2:D2 up.
.2. Adjust cell references accordingly (in D3 =IF(AND(A3=A2,C3=C2),D2+1,1).
.3. Create pivot table from A:D

.6. Overwrite Row Labels with Name.
.7. PivotTable Tools, Design, Report Layout, Show in Tabular Form and sort rows and columns A>Z.
.8. Hide Row1, ColumnG and rows and columns that show (blank).

Steps .0. and .2. in the edit are not required if the pivot table is in a different sheet from the source data (recommended).

Step .3. in the edit is a change to simplify the consequences of expanding the source data set. However introduces (blank) into pivot table that if to be hidden may need adjustment on refresh. So may be better to adjust source data range each time that changes instead: PivotTable Tools, Options, Change Data Source, Change Data Source, Select a table or range). In which case copy rather than move in .0.

Replace bigint(20) not null auto_increment by bigserial not null and datetime by timestamp

Make sure the module is defined in the package.json use npm install and then try react-native link

This seems to occur when .git/HEAD refers to a branch which does not exist. I ran into this error in a repo that had nothing in .git/refs/heads. I have no idea how the repo got into that state, I inherited from someone that left the company.

I tried to resolve with the suggested answer and still ran into some issues...

This was a solution to my problem:

ARG APP_EXE="AppName.exe"
ENV _EXE=${APP_EXE}

# Build a shell script because the ENTRYPOINT command doesn't like using ENV
RUN echo "#!/bin/bash \n mono ${_EXE}" > ./entrypoint.sh
RUN chmod +x ./entrypoint.sh

# Run the generated shell script.
ENTRYPOINT ["./entrypoint.sh"]

Specifically targeting your problem:

RUN echo "#!/bin/bash \n ./greeting --message ${ADDRESSEE}" > ./entrypoint.sh
RUN chmod +x ./entrypoint.sh
ENTRYPOINT ["./entrypoint.sh"]

The code under if __name__ == '__main__': will be executed only if the module is invoked as a script.

As an example consider the following module my_test_module.py:

# my_test_module.py

print('This is going to be printed out, no matter what')

if __name__ == '__main__':
    print('This is going to be printed out, only if user invokes the module as a script')

1st possibility: Import my_test_module.py in another module

# main.py

import my_test_module

if __name__ == '__main__':
    print('Hello from main.py')

Now if you invoke main.py:

python main.py 

>> 'This is going to be printed out, no matter what'
>> 'Hello from main.py'

Note that only the top-level print() statement in my_test_module is executed.

2nd possibility: Invoke my_test_module.py as a script

Now if you run my_test_module.py as a Python script, both print() statements will be exectued:

python my_test_module.py

>>> 'This is going to be printed out, no matter what'
>>> 'This is going to be printed out, only if user invokes the module as a script'

declare @dateOfBirth date select @dateOfBirth = '2000-01-01'

SELECT datediff(YEAR,@dateOfBirth,getdate()) as Age

The pattern I generally use is to create the row without the columns that have default constraints, then update the columns to replace the default values with supplied values (if not null).

Assuming col1 is the primary key and col4 and col5 have a default contraint

-- create initial row with default values
insert table1 (col1, col2, col3)
    values (@col1, @col2, @col3)

-- update default values, if supplied
update table1
    set col4 = isnull(@col4, col4),
        col5 = isnull(@col5, col5)
    where col1 = @col1

If you want the actual values defaulted into the table ...

-- create initial row with default values
insert table1 (col1, col2, col3)
    values (@col1, @col2, @col3)

-- create a container to hold the values actually inserted into the table
declare @inserted table (col4 datetime, col5 varchar(50))

-- update default values, if supplied
update table1
    set col4 = isnull(@col4, col4),
        col5 = isnull(@col5, col5)
    output inserted.col4, inserted.col5 into @inserted (col4, col5)
    where col1 = @col1

-- get the values defaulted into the table (optional)
select @col4 = col4, @col5 = col5 from @inserted

Cheers...

Well to obtain all different values in a Dataframe you can use distinct. As you can see in the documentation that method returns another DataFrame. After that you can create a UDF in order to transform each record.

For example:

val df = sc.parallelize(Array((1, 2), (3, 4), (1, 6))).toDF("age", "salary")

// I obtain all different values. If you show you must see only {1, 3}
val distinctValuesDF = df.select(df("age")).distinct

// Define your udf. In this case I defined a simple function, but they can get complicated.
val myTransformationUDF = udf(value => value / 10)

// Run that transformation "over" your DataFrame
val afterTransformationDF = distinctValuesDF.select(myTransformationUDF(col("age")))

I tried everything and nothing worked so here is another solution that finally worked (for me).

I had to check Enable Java EE configuration under Preferences -> Maven -> Jave EE configuration

After that you can check that more entries were added in Deployment assemblies of the project settings.

These answers all assume the file you are checking is on the server side. Unfortunately, there is no cast iron way to ensure that a file exists on the client side (e.g. if you are uploading the resume). Sure, you can do it in Javascript but you are still not going to be 100% sure on the server side.

The best way to handle this, in my opinion, is to assume that the user will actually select an appropriate file for upload, and then do whatever work you need to do to ensure the uploaded file is what you expect (hint - assume the user is trying to poison your system in every possible way with his/her input)

As its name is "numbers" it is clear it is a list of number... So an array of number... no need of the attribute type... Although I like the principle of specifying the type of field in a type attribute...

If you have a Microsoft Virtual WiFi Miniport Adapter as one of the available network adapters, you may do the following:

• Run Windows Command Processor (cmd) as Administrator
• Type: netsh wlan set hostednetwork mode=allow ssid=NAME key=PASSWORD
• Then: netsh wlan start hostednetwork
• Open "Control Panel\Network and Internet\Network Connections"
• Right-click on your active network adapter (the one that you use to connect on the internet) and then click Properties
• Then open Sharing tab
• Check "Allow other network users to connect..." and select your WiFi Miniport Adapter
• Once finished, type: netsh wlan stop hostednetwork

That's it!

A simple way is:

 git log --oneline | wc -l

oneline ensures that.

And if you need to style your form elements according to it's state (modified/not modified) dynamically or to test whether some values has actually changed, you can use the following module, developed by myself: https://github.com/betsol/angular-input-modified

It adds additional properties and methods to the form and it's child elements. With it, you can test whether some element contains new data or even test if entire form has new unsaved data.

You can setup the following watch: $scope.$watch('myForm.modified', handler) and your handler will be called if some form elements actually contains new data or if it reversed to initial state.

Also, you can use modified property of individual form elements to actually reduce amount of data sent to a server via AJAX call. There is no need to send unchanged data.

As a bonus, you can revert your form to initial state via call to form's reset() method.

You can find the module's demo here: http://plnkr.co/edit/g2MDXv81OOBuGo6ORvdt?p=preview

PostgreSQL 13 introduced FORCE option.

DROP DATABASE

DROP DATABASE drops a database ... Also, if anyone else is connected to the target database, this command will fail unless you use the FORCE option described below.

FORCE

Attempt to terminate all existing connections to the target database. It doesn't terminate if prepared transactions, active logical replication slots or subscriptions are present in the target database.

DROP DATABASE db_name WITH (FORCE);

You can try :

echo -e "newpasswd123\nnnewpasswd123" | passwd user

Create PDF from External URL

Here's an adaptation of the previous answers which utilizes html-pdf, but also combines it with requestify so it works with an external URL:

Install your dependencies

npm i -S html-pdf requestify

Then, create the script:

//MakePDF.js

var pdf = require('html-pdf');
var requestify = require('requestify');
var externalURL= 'http://www.google.com';

requestify.get(externalURL).then(function (response) {
   // Get the raw HTML response body
   var html = response.body; 
   var config = {format: 'A4'}; // or format: 'letter' - see https://github.com/marcbachmann/node-html-pdf#options

// Create the PDF
   pdf.create(html, config).toFile('pathtooutput/generated.pdf', function (err, res) {
      if (err) return console.log(err);
      console.log(res); // { filename: '/pathtooutput/generated.pdf' }
   });
});

Then you just run from the command line:

node MakePDF.js

Watch your beautify pixel perfect PDF be created for you (for free!)

If you have

<base href="/" />

It's will not load file right. Just delete it.

Let's see both the options:

1.) Use PHP inside Javascript

<script>
    <?php $temp = 'hello';?>
    console.log('<?php echo $temp; ?>');
</script>

Note: File name should be in .php only.

2.) Use Javascript variable inside PHP

<script>
  var res = "success";
</script>
<?php
   echo "<script>document.writeln(res);</script>";
?>

With AssertJ fluent assertions 3.7.0:

Assertions.assertThatCode(() -> toTest.method())
    .doesNotThrowAnyException();

you can use get_result() on the statement.

http://php.net/manual/en/mysqli-stmt.get-result.php

If all your files are named similarly you could simply do:

cat *.log >> output.log

Think I figured out how to do it:

- (void)drawRect:(NSRect)dirtyRect {
    // Fill in background Color
    CGContextRef context = (CGContextRef) [[NSGraphicsContext currentContext] graphicsPort];
    CGContextSetRGBFillColor(context, 0.227,0.251,0.337,0.8);
    CGContextFillRect(context, NSRectToCGRect(dirtyRect));
}

You are running Python 2 code on Python 3. In Python 3, the module has been renamed to http.client.

You could try to run the 2to3 tool on your code, and try to have it translated automatically. References to httplib will automatically be rewritten to use http.client instead.

Write router in place of Main in render (last line in the code). Like this ReactDOM.render(router, document.getElementById('root'));

Have you tried setting the selection properties of your tableView like this:

tableView.allowsMultipleSelection = NO; tableView.allowsMultipleSelectionDuringEditing = YES; tableView.allowsSelection = NO; tableView.allowsSelectionDuringEditing YES; 

If you want more fine-grain control over when selection is allowed you can override - (NSIndexPath *)tableView:(UITableView *)tableView willSelectRowAtIndexPath:(NSIndexPath *)indexPath in your UITableView delegate. The documentation states:

Return Value An index-path object that confirms or alters the selected row. Return an NSIndexPath object other than indexPath if you want another cell to be selected. Return nil if you don't want the row selected. 

You can have this method return nil in cases where you don't want the selection to happen.

Use the parseFloat method to parse the strings into floating point numbers:

parseFloat(num1) + parseFloat(num2)

For me the most elegant solution is this one:

XMLGregorianCalendar result = DatatypeFactory.newInstance()
    .newXMLGregorianCalendar("2014-01-07");

Using Java 8.

Extended example:

XMLGregorianCalendar result = DatatypeFactory.newInstance()
    .newXMLGregorianCalendar("2014-01-07");
System.out.println(result.getDay());
System.out.println(result.getMonth());
System.out.println(result.getYear());

This prints out:

7
1
2014

I have found the following has worked for me:

java -jar my-awesome-java-prog.jar --spring.config.location=file:/path-to-config-dir/

with file: added.

LATE EDIT

Of course, this command line is never run as it is in production.

Rather I have

• [possibly several layers of] shell scripts in source control with place holders for all parts of the command that could change (name of the jar, path to config...)
• ansible deployment scripts that will deploy the shell scripts and replace the place holders by the actual value.

According to the API, the headers can all be passed in using requests.get:

import requests
r=requests.get("http://www.example.com/", headers={"content-type":"text"})

I came across an amazing resource on css-tricks: https://css-tricks.com/using-svg/

There are a handful of solutions explained there.

I preferred the one that required minimal edits to the source svg, and also didn't require it to be embedded into the html document. This option utilizes the <object> tag.

Add the svg file into your html using <object>; I also declared html attributes width and height. Using these width and heights the svg document does not get scaled, I worked around that using a css transform: scale(...) statement for the svg tag in my associated svg css file.

<object type="image/svg+xml" data="myfile.svg" width="64" height="64"></object>

Create a css file to attach to your svn document. My source svg path was scaled to 16px, I upscaled it to 64 with a factor of four. It only had one path so I did not need to select it more specifically, however the path had a fill attribute so I had to use !IMPORTANT to force the css to take precedent.

#svg2 {
    width: 64px; height: 64px;
    transform: scale(4);
}
path {
    fill: #333 !IMPORTANT;
}

Edit your target svg file, before the opening <svg tag, to include a stylesheet; Note that the href is relative to the svg file url.

<?xml-stylesheet type="text/css" href="myfile.css" ?>

This happens because $cOTLdata is not null but the index 'char_data' does not exist. Previous versions of PHP may have been less strict on such mistakes and silently swallowed the error / notice while 7.4 does not do this anymore.

To check whether the index exists or not you can use isset():

isset($cOTLdata['char_data'])

Which means the line should look something like this:

$len = isset($cOTLdata['char_data']) ? count($cOTLdata['char_data']) : 0;

Note I switched the then and else cases of the ternary operator since === null is essentially what isset already does (but in the positive case).

Try this simple in one line of code:-

$data= json_decode( json_encode($data), true);

Hope it helps :)

Well, most convenient and safest way is to use JBoss update site within Eclipse software updates (Help -> Software Updates... -> Add Site...):

The latest stable release update site for JBoss Tools

There you can find Hibernate tools together with other handy JBoss plugins.

<?php 
            $ConvertDateBack = Zend_Controller_Action_HelperBroker::getStaticHelper('ConvertDate');
            $disabledDaysRange = array();
            foreach($this->reservedDates as $dates) {
                 $date = $ConvertDateBack->ConvertDateBack($dates->reservation_date);
                 $disabledDaysRange[] = $date;
                 array_push($disabledDaysRange, $date);
            }

            $finalArr = json_encode($disabledDaysRange);
?>
<script>
var disabledDaysRange = <?=$finalArr?>;

</script>

Found it hidden in Twitter API Docs

Twitter's naming is just too confusing.

A[A==NDV]=numpy.nan

A==NDV will produce a boolean array that can be used as an index for A

Tell grep to treat your input as fixed string using -F option.

grep -F '*^%Q&$*&^@$&*!^@$*&^&^*&^&' application.log

Option -n is required to get the line number,

grep -Fn '*^%Q&$*&^@$&*!^@$*&^&^*&^&' application.log

Try this

<form method="post" id="reg" name="reg" action="<?php echo htmlspecialchars($_SERVER['PHP_SELF']);?>"

Works well :)

Yes, it is possible both in Sublime Text 2 and 3 (which you should really upgrade to if you haven't already). Select View ? Ruler ? 80 (there are several other options there as well). If you like to actually wrap your text at 80 columns, select View ? Word Wrap Column ? 80. Make sure that View ? Word Wrap is selected.

To make your selections permanent (the default for all opened files or views), open Preferences ? Settings—User and use any of the following rules:

{
    // set vertical rulers in specified columns.
    // Use "rulers": [80] for just one ruler
    // default value is []
    "rulers": [80, 100, 120],

    // turn on word wrap for source and text
    // default value is "auto", which means off for source and on for text
    "word_wrap": true,

    // set word wrapping at this column
    // default value is 0, meaning wrapping occurs at window width
    "wrap_width": 80
}

These settings can also be used in a .sublime-project file to set defaults on a per-project basis, or in a syntax-specific .sublime-settings file if you only want them to apply to files written in a certain language (Python.sublime-settings vs. JavaScript.sublime-settings, for example). Access these settings files by opening a file with the desired syntax, then selecting Preferences ? Settings—More ? Syntax Specific—User.

As always, if you have multiple entries in your settings file, separate them with commas , except for after the last one. The entire content should be enclosed in curly braces { }. Basically, make sure it's valid JSON.

If you'd like a key combo to automatically set the ruler at 80 for a particular view/file, or you are interested in learning how to set the value without using the mouse, please see my answer here.

Finally, as mentioned in another answer, you really should be using a monospace font in order for your code to line up correctly. Other types of fonts have variable-width letters, which means one 80-character line may not appear to be the same length as another 80-character line with different content, and your indentations will look all messed up. Sublime has monospace fonts set by default, but you can of course choose any one you want. Personally, I really like Liberation Mono. It has glyphs to support many different languages and Unicode characters, looks good at a variety of different sizes, and (most importantly for a programming font) clearly differentiates between 0 and O (digit zero and capital letter oh) and 1 and l (digit one and lowercase letter ell), which not all monospace fonts do, unfortunately. Version 2.0 and later of the font are licensed under the open-source SIL Open Font License 1.1 (here is the FAQ).

The delete operator deletes only a reference, never an object itself. If it did delete the object itself, other remaining references would be dangling, like a C++ delete. (And accessing one of them would cause a crash. To make them all turn null would mean having extra work when deleting or extra memory for each object.)

Since Javascript is garbage collected, you don't need to delete objects themselves - they will be removed when there is no way to refer to them anymore.

It can be useful to delete references to an object if you are finished with them, because this gives the garbage collector more information about what is able to be reclaimed. If references remain to a large object, this can cause it to be unreclaimed - even if the rest of your program doesn't actually use that object.

You can also use the filter function from the dplyr package which returns rows with matching conditions.

> library(dplyr)

> nrow(filter(aaa, sex == 1 & group1 == 2))
[1] 3
> nrow(filter(aaa, sex == 1 & group2 == "A"))
[1] 2

As said before, @Column(unique = true) is a shortcut to UniqueConstraint when it is only a single field.

From the example you gave, there is a huge difference between both.

@Column(unique = true)
@ManyToOne(optional = false, fetch = FetchType.EAGER)
private ProductSerialMask mask;

@Column(unique = true)
@ManyToOne(optional = false, fetch = FetchType.EAGER)
private Group group;

This code implies that both mask and group have to be unique, but separately. That means that if, for example, you have a record with a mask.id = 1 and tries to insert another record with mask.id = 1, you'll get an error, because that column should have unique values. The same aplies for group.

On the other hand,

@Table(
   name = "product_serial_group_mask", 
   uniqueConstraints = {@UniqueConstraint(columnNames = {"mask", "group"})}
)

Implies that the values of mask + group combined should be unique. That means you can have, for example, a record with mask.id = 1 and group.id = 1, and if you try to insert another record with mask.id = 1 and group.id = 2, it'll be inserted successfully, whereas in the first case it wouldn't.

If you'd like to have both mask and group to be unique separately and to that at class level, you'd have to write the code as following:

@Table(
        name = "product_serial_group_mask",
        uniqueConstraints = {
                @UniqueConstraint(columnNames = "mask"),
                @UniqueConstraint(columnNames = "group")
        }
)

This has the same effect as the first code block.

GET recipe

For this task you can use already available plugins and bootstrap extensions. Or you can make your own confirmation popup with just 3 lines of code. Check it out.

Say we have this links (note data-href instead of href) or buttons that we want to have delete confirmation for:

<a href="#" data-href="delete.php?id=23" data-toggle="modal" data-target="#confirm-delete">Delete record #23</a>

<button class="btn btn-default" data-href="/delete.php?id=54" data-toggle="modal" data-target="#confirm-delete">
    Delete record #54
</button>

Here #confirm-delete points to a modal popup div in your HTML. It should have an "OK" button configured like this:

<div class="modal fade" id="confirm-delete" tabindex="-1" role="dialog" aria-labelledby="myModalLabel" aria-hidden="true">
    <div class="modal-dialog">
        <div class="modal-content">
            <div class="modal-header">
                ...
            </div>
            <div class="modal-body">
                ...
            </div>
            <div class="modal-footer">
                <button type="button" class="btn btn-default" data-dismiss="modal">Cancel</button>
                <a class="btn btn-danger btn-ok">Delete</a>
            </div>
        </div>
    </div>
</div>

Now you only need this little javascript to make a delete action confirmable:

$('#confirm-delete').on('show.bs.modal', function(e) {
    $(this).find('.btn-ok').attr('href', $(e.relatedTarget).data('href'));
});

So on show.bs.modal event delete button href is set to URL with corresponding record id.

Demo: http://plnkr.co/edit/NePR0BQf3VmKtuMmhVR7?p=preview

POST recipe

I realize that in some cases there might be needed to perform POST or DELETE request rather then GET. It it still pretty simple without too much code. Take a look at the demo below with this approach:

// Bind click to OK button within popup
$('#confirm-delete').on('click', '.btn-ok', function(e) {

  var $modalDiv = $(e.delegateTarget);
  var id = $(this).data('recordId');

  $modalDiv.addClass('loading');
  $.post('/api/record/' + id).then(function() {
     $modalDiv.modal('hide').removeClass('loading');
  });
});

// Bind to modal opening to set necessary data properties to be used to make request
$('#confirm-delete').on('show.bs.modal', function(e) {
  var data = $(e.relatedTarget).data();
  $('.title', this).text(data.recordTitle);
  $('.btn-ok', this).data('recordId', data.recordId);
});

Bootstrap 2.3

Here is an original version of the code I made when I was answering this question for Bootstrap 2.3 modal.

$('#modal').on('show', function() {
    var id = $(this).data('id'),
        removeBtn = $(this).find('.danger');
    removeBtn.attr('href', removeBtn.attr('href').replace(/(&|\?)ref=\d*/, '$1ref=' + id));
});

Demo: http://jsfiddle.net/MjmVr/1595/

var objToJson = { };
objToJson.response = response;
response.write(JSON.stringify(objToJson));

If you alert(JSON.stringify(objToJson)) you will get {"response":"value"}

I know that this is a very old post and I am probably very late to the party, but hopefully this will help someone else. This has worked for me.

phone_words = input('Phone: ')
numbered_words = {
    '0': 'zero',
    '1': 'one',
    '2': 'two',
    '3': 'three',
    '4': 'four',
    '5': 'five',
    '6': 'six',
    '7': 'seven',
    '8': 'eight',
    '9': 'nine'
}
output = ""
for ch in phone_words:
    output += numbered_words.get(ch, "!") + " "
phone_words = numbered_words

print(output)

Can I use a field of the type ... and retrieve it after the GET / POST method ...

Yes (haven't you tried?)

Are there any other ways of using hidden fields in PHP?

You mean other ways of retrieving the value? No.
Of course you can use hidden fields for what ever you want.

Btw. input fiels have no end tag. So write either just <input ...> or as self-closing tag <input .../>.

I know this question is older but I was looking thru the answers and thought that I might be able to expand on the "dynamic" portion of the problem and possibly help someone out.

First and foremost I built this solution to solve a problem a couple of coworkers were having with inconstant and large data sets needing to be pivoted quickly.

This solution requires the creation of a stored procedure so if that is out of the question for your needs please stop reading now.

This procedure is going to take in the key variables of a pivot statement to dynamically create pivot statements for varying tables, column names and aggregates. The Static column is used as the group by / identity column for the pivot(this can be stripped out of the code if not necessary but is pretty common in pivot statements and was necessary to solve the original issue), the pivot column is where the end resultant column names will be generated from, and the value column is what the aggregate will be applied to. The Table parameter is the name of the table including the schema (schema.tablename) this portion of the code could use some love because it is not as clean as I would like it to be. It worked for me because my usage was not publicly facing and sql injection was not a concern. The Aggregate parameter will accept any standard sql aggregate 'AVG', 'SUM', 'MAX' etc. The code also defaults to MAX as an aggregate this is not necessary but the audience this was originally built for did not understand pivots and were typically using max as an aggregate.

Lets start with the code to create the stored procedure. This code should work in all versions of SSMS 2005 and above but I have not tested it in 2005 or 2016 but I can not see why it would not work.

create PROCEDURE [dbo].[USP_DYNAMIC_PIVOT]
    (
        @STATIC_COLUMN VARCHAR(255),
        @PIVOT_COLUMN VARCHAR(255),
        @VALUE_COLUMN VARCHAR(255),
        @TABLE VARCHAR(255),
        @AGGREGATE VARCHAR(20) = null
    )

AS


BEGIN

SET NOCOUNT ON;
declare @AVAIABLE_TO_PIVOT NVARCHAR(MAX),
        @SQLSTRING NVARCHAR(MAX),
        @PIVOT_SQL_STRING NVARCHAR(MAX),
        @TEMPVARCOLUMNS NVARCHAR(MAX),
        @TABLESQL NVARCHAR(MAX)

if isnull(@AGGREGATE,'') = '' 
    begin
        SET @AGGREGATE = 'MAX'
    end


 SET @PIVOT_SQL_STRING =    'SELECT top 1 STUFF((SELECT distinct '', '' + CAST(''[''+CONVERT(VARCHAR,'+ @PIVOT_COLUMN+')+'']''  AS VARCHAR(50)) [text()]
                            FROM '+@TABLE+'
                            WHERE ISNULL('+@PIVOT_COLUMN+','''') <> ''''
                            FOR XML PATH(''''), TYPE)

INSERT INTO @TAB EXEC SP_EXECUTESQL  @PIVOT_SQL_STRING, @AVAIABLE_TO_PIVOT 

SET @AVAIABLE_TO_PIVOT = (SELECT * FROM @TAB)


SET @TEMPVARCOLUMNS = (SELECT replace(@AVAIABLE_TO_PIVOT,',',' nvarchar(255) null,') + ' nvarchar(255) null')


SET @SQLSTRING = 'DECLARE @RETURN_TABLE TABLE ('+@STATIC_COLUMN+' NVARCHAR(255) NULL,'+@TEMPVARCOLUMNS+')  
                    INSERT INTO @RETURN_TABLE('+@STATIC_COLUMN+','+@AVAIABLE_TO_PIVOT+')

                    select * from (
                    SELECT ' + @STATIC_COLUMN + ' , ' + @PIVOT_COLUMN + ', ' + @VALUE_COLUMN + ' FROM '+@TABLE+' ) a

                    PIVOT
                    (
                    '+@AGGREGATE+'('+@VALUE_COLUMN+')
                    FOR '+@PIVOT_COLUMN+' IN ('+@AVAIABLE_TO_PIVOT+')
                    ) piv

                    SELECT * FROM @RETURN_TABLE'



EXEC SP_EXECUTESQL @SQLSTRING

END

Next we will get our data ready for the example. I have taken the data example from the accepted answer with the addition of a couple of data elements to use in this proof of concept to show the varied outputs of the aggregate change.

create table temp
(
    date datetime,
    category varchar(3),
    amount money
)

insert into temp values ('1/1/2012', 'ABC', 1000.00)
insert into temp values ('1/1/2012', 'ABC', 2000.00) -- added
insert into temp values ('2/1/2012', 'DEF', 500.00)
insert into temp values ('2/1/2012', 'DEF', 1500.00) -- added
insert into temp values ('2/1/2012', 'GHI', 800.00)
insert into temp values ('2/10/2012', 'DEF', 700.00)
insert into temp values ('2/10/2012', 'DEF', 800.00) -- addded
insert into temp values ('3/1/2012', 'ABC', 1100.00)

The following examples show the varied execution statements showing the varied aggregates as a simple example. I did not opt to change the static, pivot, and value columns to keep the example simple. You should be able to just copy and paste the code to start messing with it yourself

exec [dbo].[USP_DYNAMIC_PIVOT] 'date','category','amount','dbo.temp','sum'
exec [dbo].[USP_DYNAMIC_PIVOT] 'date','category','amount','dbo.temp','max'
exec [dbo].[USP_DYNAMIC_PIVOT] 'date','category','amount','dbo.temp','avg'
exec [dbo].[USP_DYNAMIC_PIVOT] 'date','category','amount','dbo.temp','min'

This execution returns the following data sets respectively.

try use CMAKE_GENERATOR_PLATFORM

e.g.

// x86
cmake -DCMAKE_GENERATOR_PLATFORM=x86 . 

// x64
cmake -DCMAKE_GENERATOR_PLATFORM=x64 . 

Additionally, adding na.rm= TRUE to your geom_bar() will work.

ggplot(data = MyData,aes(x= the_variable, fill=the_variable, na.rm = TRUE)) + 
   geom_bar(stat="bin", na.rm = TRUE)

I ran into this issue with a loop in a time series and this fixed it. The missing data is removed and the results are otherwise uneffected.

I had the same issue, but I found a good solution here: Stop caching for PHP 5.5.3 in MAMP

Basically find the php.ini file and comment out the OPCache lines. I hope this alternative answer helps others else out as well.

new version of postman app has the ability to do that programmatically in pre-request or tests scripts since 2019/08

see more examples here: Delete cookies programmatically · Issue #3312 · postmanlabs/postman-app-support

clear all cookies

const jar = pm.cookies.jar();

jar.clear(pm.request.url, function (error) {
  // error - <Error>
});

get all cookies

const jar = pm.cookies.jar();

jar.getAll('http://example.com', function (error, cookies) {
  // error - <Error>
  // cookies - <PostmanCookieList>
  // PostmanCookieList: https://www.postmanlabs.com/postman-collection/CookieList.html

get specific cookie

const jar = pm.cookies.jar();

jar.get('http://example.com', 'token', function (error, value) {
  // error - <Error>
  // value - <String>
});

There are two different ways of generating a UUID.

If you just need a unique ID, you want a version 1 or version 4.

• Version 1: This generates a unique ID based on a network card MAC address and a timer. These IDs are easy to predict (given one, I might be able to guess another one) and can be traced back to your network card. It's not recommended to create these.

• Version 4: These are generated from random (or pseudo-random) numbers. If you just need to generate a UUID, this is probably what you want.

If you need to always generate the same UUID from a given name, you want a version 3 or version 5.

• Version 3: This generates a unique ID from an MD5 hash of a namespace and name. If you need backwards compatibility (with another system that generates UUIDs from names), use this.

• Version 5: This generates a unique ID from an SHA-1 hash of a namespace and name. This is the preferred version.

• Built in python 3
• Installable via pip

If you want to use form's reset feature, you'd better to use this:

$('input[type=checkbox]').prop('checked',true); 

OR

$('input[type=checkbox]').prop('checked',false);

Looks like removeAttr() can not be reset by form.reset().

Tk provides a helper function that can do this as tk::PlaceWindow, but I don't believe it has been exposed as a wrapped method in Tkinter. You would center a widget using the following:

from tkinter import *

app = Tk()
app.eval('tk::PlaceWindow %s center' % app.winfo_pathname(app.winfo_id()))
app.mainloop()

This function should deal with multiple displays correctly as well. It also has options to center over another widget or relative to the pointer (used for placing popup menus), so that they don't fall off the screen.

An alternative approach if interested - with an extra intermediate class to use the normal OOO way. This simplifies the usage with parent::methodname

trait A {
    function calc($v) {
        return $v+1;
    }
}

// an intermediate class that just uses the trait
class IntClass {
    use A;
}

// an extended class from IntClass
class MyClass extends IntClass {
    function calc($v) {
        $v++;
        return parent::calc($v);
    }
}

That is not an nginx configuration file. It is part of an nginx configuration file.

The nginx configuration file (usually called nginx.conf) will look like:

events {
    ...
}
http {
    ...
    server {
        ...
    }
}

The server block is enclosed within an http block.

Often the configuration is distributed across multiple files, by using the include directives to pull in additional fragments (for example from the sites-enabled directory).

Use sudo nginx -t to test the complete configuration file, which starts at nginx.conf and pulls in additional fragments using the include directive. See this document for more.

You could also use supervisord which is a very handy daemon, which can be used to easily control services. These services are defined by simple configuration files defining what to execute with which user in which directory and so forth, there are a zillion options. supervisord has a very simple syntax, so it makes a very good alternative to writing SysV init scripts.

Here a simple supervisord configuration file for the program you are trying to run/control. (put this into /etc/supervisor/conf.d/yourapp.conf)

/etc/supervisor/conf.d/yourapp.conf

[program:yourapp]
command=/usr/bin/java -jar /path/to/application.jar
user=usertorun
autostart=true
autorestart=true
startsecs=10
startretries=3
stdout_logfile=/var/log/yourapp-stdout.log
stderr_logfile=/var/log/yourapp-stderr.log

To control the application you would need to execute supervisorctl, which will present you with a prompt where you could start, stop, status yourapp.

CLI

# sudo supervisorctl
yourapp             RUNNING   pid 123123, uptime 1 day, 15:00:00
supervisor> stop yourapp
supervisor> start yourapp

If the supervisord daemon is already running and you've added the configuration for your serivce without restarting the daemon you can simply do a reread and update command in the supervisorctl shell.

This really gives you all the flexibilites you would have using SysV Init scripts, but easy to use and control. Take a look at the documentation.

Do you need to do it from mgmt studio? Here's how we do it from cmd line:

"C:\Program Files\Microsoft SQL Server\MSSQL\Binn\TEXTCOPY.exe" /S < Server> /D < DataBase> /T mytable /C mypictureblob /F "C:\picture.png" /W"where RecId=" /I

I encountered this issue on python 2.7.9.
To fix it, I installed tk and tcl, and then rebuild python code and reinstall, and during configure, I set the path for tk and tcl explicitly, by:

./configure --with-tcltk-includes="-I/usr/include" --with-tcltk-libs="-L/usr/lib64 -ltcl8.5 -L/usr/lib64 -ltk8.5"

I experienced the same problem when I copied a text that has an apostrophe from a Word document to my HTML code.

To resolve the issue, all I did was deleted the particular word in my HTML and typed it directly, including the apostrophe. This action nullified the original copy and paste acton and displayed the newly typed apostrophe correctly

with DataFrame: df_data

>>> df_data
  id   name  value
0  a  ampha      1
1  b   beta      2
2  c     ce      3

I tried:

>>> getattr(df_data, 'value').isin([1]).any()
True
>>> getattr(df_data, 'value').isin(['1']).any()
True

but:

>>> 1 in getattr(df_data, 'value')
True
>>> '1' in getattr(df_data, 'value')
False

So fun :D

you need to make county_ID as index for the right frame:

frame_2.join ( frame_1.set_index( [ 'county_ID' ], verify_integrity=True ),
               on=[ 'countyid' ], how='left' )

for your information, in pandas left join breaks when the right frame has non unique values on the joining column. see this bug.

so you need to verify integrity before joining by , verify_integrity=True

if ($done)
{
    header("Location: /url/to/the/other/page");
    exit;
}

If 0 is your default value, you can just use a simple assignment:

ddlCustomerNumber.SelectedValue = GetCustomerNumberCookie().ToString();

This automatically selects the proper list item, if the DDL contains the value of the cookie. If it doesn't contain it, this call won't change the selection, so it stays at the default selection. If the latter one is the same as value 0, then it's the perfect solution for you.

I use this mechanism quite a lot and find it very handy.

Just an additional note - if the server runs on a port other than 80 (as might be common on a development/intranet machine) then HTTP_HOST contains the port, while SERVER_NAME does not.

$_SERVER['HTTP_HOST'] == 'localhost:8080'
$_SERVER['SERVER_NAME'] == 'localhost'

(At least that's what I've noticed in Apache port-based virtualhosts)

As Mike has noted below, HTTP_HOST does not contain :443 when running on HTTPS (unless you're running on a non-standard port, which I haven't tested).

It's actually much easier with jQuery's promise API:

$.ajax(
            type: "GET",
            url: requestURL,
        ).then((success) =>
            console.dir(success)
        ).failure((failureResponse) =>
            console.dir(failureResponse)
        )

Alternatively, you can pass in of bind functions to each result callback; the order of parameters is: (success, failure). So long as you specify a function with at least 1 parameter, you get access to the response. So, for example, if you wanted to check the response text, you could simply do:

$.ajax(
            type: "GET",
            url: @get("url") + "logout",
            beforeSend: (xhr) -> xhr.setRequestHeader("token", currentToken)
        ).failure((response) -> console.log "Request was unauthorized" if response.status is 401

Something like this should work unless I'm missing the point:

import json
import urllib2
json.load(urllib2.urlopen("url"))

To check Clustered Index exist on particular table or not:

SELECT * FROM SYS.indexes 
WHERE index_id = 1 AND name IN (SELECT CONSTRAINT_NAME FROM INFORMATION_SCHEMA.TABLE_CONSTRAINTS WHERE TABLE_NAME = 'Table_Name')

echo"==================PS COMMAND SNAPSHOT=============================================================="

needs to be

echo "==================PS COMMAND SNAPSHOT=============================================================="

Else, a program or command named echo"===... is searched.

more problems:

If you do a grep (-A1: + 1 line context)

grep -A1 "if " cldtest.sh 

you find some embedded ifs, and 4 if/then blocks.

grep "fi " cldtest.sh 

only reveals 3 matching fi statements. So you forgot one fi too.

I agree with camh, that correct indentation from the beginning helps to avoid such errors. Finding the desired way later means double work in such spaghetti code.

std::string trimmed(std::string str ) {
if(str.length() == 0 ) { return "" ; }
else if ( str == std::string(" ") ) { return "" ; } 
else {
    while(str.at(0) == ' ') { str.erase(0, 1);}
    while(str.at(str.length()-1) == ' ') { str.pop_back() ; }
    return str ;
    } 
}

In case, someone looking for lower version -

For SQL Server 2000:

sp_changeobjectowner @objname = 'dbo.Employess' , @newowner ='exe'

Or better

window.location.assign("relative or absolute address");

that tends to work best across all browsers and mobile

All the answers above are helpful but none solved my issue. In my production file, my STATIC_URL was https://<URL>/static and I used the same STATIC_URL in my dev settings.py file.

This causes a silent failure in django/conf/urls/static.py.

The test elif not settings.DEBUG or '://' in prefix: picks up the '//' in the URL and does not add the static URL pattern, causing no static files to be found.

It would be thoughtful if Django spit out an error message stating you can't use a http(s):// with DEBUG = True

I had to change STATIC_URL to be '/static/'

Looks like the type is boolean and therefore can never be null and should be false by default.

I have recently tried the following approach which seems to work fine, although I am not 100% sure if there might be any side effects:

'use strict';

import * as models from "../../models";

module.exports = {

  up: function (queryInterface, Sequelize) {

    return queryInterface.createTable(models.Role.tableName, models.Role.attributes)
    .then(() => queryInterface.createTable(models.Team.tableName, models.Team.attributes))
    .then(() => queryInterface.createTable(models.User.tableName, models.User.attributes))

  },

  down: function (queryInterface, Sequelize) {
    ...
  }

};

When running the migration above using sequelize db:migrate, my console says:

Starting 'db:migrate'...
Finished 'db:migrate' after 91 ms
== 20160113121833-create-tables: migrating =======
== 20160113121833-create-tables: migrated (0.518s)

All the tables are there, everything (at least seems to) work as expected. Even all the associations are there if they are defined correctly.

Just add ToolTip tool from toolbox to the form and add this code in a mousemove event of any control you want to make the tooltip start on its mousemove

private void textBox3_MouseMove(object sender, MouseEventArgs e)
    {
      toolTip1.SetToolTip(textBox3,"Tooltip text"); // you can change the first parameter (textbox3) on any control you wanna focus
    }

hope it helps

peace

Also you could use

${pageContext.request.requestURI}
