This code works for my application:

def ShowData(data, names):
    i = 0
    while i < data.shape[0]:
        print(names[i] + ": ")
        j = 0
        while j < data.shape[1]:
            print(data[i][j])
            j += 1
        print("")
        i += 1

def Main():
    print("The sample data is: ")
    fname = 'ANOVA.csv'
    csv = numpy.genfromtxt(fname, dtype=str, delimiter=",")
    num_rows = csv.shape[0]
    num_cols = csv.shape[1]
    names = csv[:,0]
    data = numpy.genfromtxt(fname, usecols = range(1,num_cols), delimiter=",")
    print(names)
    print(str(num_rows) + "x" + str(num_cols))
    print(data)
    ShowData(data, names)

Python-2 output:

The sample data is:

   //code to get results from db for those params.

Is this a bug or feature?

Looks like undefined behaviour. I know that, in practice, you can change the default encoding using a command-line property, but I don't think what happens when you do this is defined.

Bug ID: 4153515 on problems setting this property:

This is not a bug. The "file.encoding" property is not required by the J2SE platform specification; it's an internal detail of Sun's implementations and should not be examined or modified by user code. It's also intended to be read-only; it's technically impossible to support the setting of this property to arbitrary values on the command line or at any other time during program execution.

The preferred way to change the default encoding used by the VM and the runtime system is to change the locale of the underlying platform before starting your Java program.

I cringe when I see people setting the encoding on the command line - you don't know what code that is going to affect.

If you do not want to use the default encoding, set the encoding you do want explicitly via the appropriate method/constructor.

From your referenced page:

http://googlecode.blogspot.com/2009/12/google-analytics-launches-asynchronous.html

Firefox 3.6 is the first browser to officially offer support for this new feature. If you're curious, here are more details on the official HTML5 async specification.

In Android studio CTRL + SHIFT + / for windows.

Delegates are extremely useful when wanting to declare a block of code that you want to pass around. For example when using a generic retry mechanism.

Pseudo:

function Retry(Delegate func, int numberOfTimes)
    try
    {
       func.Invoke();
    }
    catch { if(numberOfTimes blabla) func.Invoke(); etc. etc. }

Or when you want to do late evaluation of code blocks, like a function where you have some Transform action, and want to have a BeforeTransform and an AfterTransform action that you can evaluate within your Transform function, without having to know whether the BeginTransform is filled, or what it has to transform.

And of course when creating event handlers. You don't want to evaluate the code now, but only when needed, so you register a delegate that can be invoked when the event occurs.

Just call comboBox.updateUI() after doing comboBox.setSelectedItem or comboBox.setSelectedIndex or comboModel.setSelectedItem

I think you can benefit from using a MemoryStream. You can fill it with the string bytes that you obtain by using the GetBytes method of the Encoding class.

You can create a link , having get variable in href.

<a href="www.site.com/hello?getVar=value" >...</a>

Another easy way:

//In your ListViewActivity:
public void refreshListView() {
    listAdapter = new ListAdapter(this);
    setListAdapter(listAdapter);
}

The Phusion guys have some nice plugin for this.

Iterators make your code more generic.
Every standard library container provides an iterator hence if you change your container class in future the loop wont be affected.

Two things come to mind:

• Context is all-important. If you're a games programmer or in an engineering discipline, then math may be vital for your job. I do database and web development, therefore high school-level math is fine for me.
• You are very likely to be reusing someone else's pre-built math code rather than reinventing the wheel, especially in fields like encryption and compression. (This may also apply if you're in games development using a third party physics tool or a 3D engine.) Having a framework of tried and tested routines for use in your programs prevents errors and potential security weaknesses - definitely a good thing.

Just create a data frame of empty vectors:

collect1 <- data.frame(id = character(0), max1 = numeric(0), max2 = numeric(0))

But if you know how many rows you're going to have in advance, you should just create the data frame with that many rows to start with.

While the marked answer gets it working, all you really need to add to the webconfig is:

    <handlers>
      <!-- Your other remove tags-->
      <remove name="UrlRoutingModule-4.0"/>
      <!-- Your other add tags-->
      <add name="UrlRoutingModule-4.0" path="*" verb="*" type="System.Web.Routing.UrlRoutingModule" preCondition=""/>
    </handlers>

Note that none of those have a particular order, though you want your removes before your adds.

The reason that we end up getting a 404 is because the Url Routing Module only kicks in for the root of the website in IIS. By adding the module to this application's config, we're having the module to run under this application's path (your subdirectory path), and the routing module kicks in.

Based on the other answers and changing data-dismiss to data-hide, this example handles opening the alert from a link and allows the alert to be opened and closed repeatedly

$('a.show_alert').click(function() {
    var $theAlert = $('.my_alert'); /* class on the alert */
    $theAlert.css('display','block');
   // set up the close event when the alert opens
   $theAlert.find('a[data-hide]').click(function() {
     $(this).parent().hide(); /* hide the alert */
   });
});

If you are using bootstrap-datepicker you may use this style:

$('#datepicker').datepicker('setStartDate', "01-01-1900");

you could check the files

/proc/[pid]/task/[thread ids]/status

Is one just an extension?

Pretty much, yes - RFC 3339 is listed as a profile of ISO 8601. Most notably RFC 3339 specifies a complete representation of date and time (only fractional seconds are optional). The RFC also has some small, subtle differences. For example truncated representations of years with only two digits are not allowed -- RFC 3339 requires 4-digit years, and the RFC only allows a period character to be used as the decimal point for fractional seconds. The RFC also allows the "T" to be replaced by a space (or other character), while the standard only allows it to be omitted (and only when there is agreement between all parties using the representation).

I wouldn't worry too much about the differences between the two, but on the off-chance your use case runs in to them, it'd be worth your while taking a glance at:

• RFC 3339
• Wikipedia entry on ISO 8601

the first case can also be easily done as:

A=A[0]

It is a bad idea to select * from anything, period. This is why SSMS adds every field name, even if there are hundreds, instead of select *. It is extremely inefficient regardless of how large the table is. If you don't know what the fields are, its still more efficient to pull them out of the INFORMATION_SCHEMA database than it is to select *.

A better query would be:

SELECT 
 COLUMN_NAME, 
 Case 
  When DATA_TYPE In ('varchar', 'char', 'nchar', 'nvarchar', 'binary') 
  Then convert(varchar(MAX), CHARACTER_MAXIMUM_LENGTH)  
  When DATA_TYPE In ('numeric', 'int', 'smallint', 'bigint', 'tinyint') 
  Then convert(varchar(MAX), NUMERIC_PRECISION) 
  When DATA_TYPE = 'bit' 
  Then convert(varchar(MAX), 1)
  When DATA_TYPE IN ('decimal', 'float') 
  Then convert(varchar(MAX), Concat(Concat(NUMERIC_PRECISION, ', '), NUMERIC_SCALE)) 
  When DATA_TYPE IN ('date', 'datetime', 'smalldatetime', 'time', 'timestamp') 
  Then '' 
 End As DATALEN, 
 DATA_TYPE 
FROM INFORMATION_SCHEMA.COLUMNS 
Where 
 TABLE_NAME = ''

To move up, remove and then add.

To remove - ArrayList.remove and assign the returned object to a variable
Then add this object back at the required index -ArrayList.add(int index, E element)

In my case I was loading the google script via http while my server had SSL and its being loaded over https. So I had to load script via https

public partial class MainWindow : Window
{
    public MainWindow()
    {
        InitializeComponent();
        DataContext = new ViewModelBase();
    }
}

The ViewModel:

public class ViewModelBase
{
    private ICommand _clickCommand;
    public ICommand ClickCommand
    {
        get
        {
            return _clickCommand ?? (_clickCommand = new CommandHandler(() => MyAction(), ()=> CanExecute));
        }
    }
     public bool CanExecute
     {
        get
        {
            // check if executing is allowed, i.e., validate, check if a process is running, etc. 
            return true/false;
        }
     }

    public void MyAction()
    {

    }
}

Command Handler:

 public class CommandHandler : ICommand
{
    private Action _action;
    private Func<bool> _canExecute;

    /// <summary>
    /// Creates instance of the command handler
    /// </summary>
    /// <param name="action">Action to be executed by the command</param>
    /// <param name="canExecute">A bolean property to containing current permissions to execute the command</param>
    public CommandHandler(Action action, Func<bool> canExecute)
    {
        _action = action;
        _canExecute = canExecute;
    }

    /// <summary>
    /// Wires CanExecuteChanged event 
    /// </summary>
    public event EventHandler CanExecuteChanged
    {
        add { CommandManager.RequerySuggested += value; }
        remove { CommandManager.RequerySuggested -= value; }
    }

    /// <summary>
    /// Forcess checking if execute is allowed
    /// </summary>
    /// <param name="parameter"></param>
    /// <returns></returns>
    public bool CanExecute(object parameter)
    {
        return _canExecute.Invoke();
    }

    public void Execute(object parameter)
    {
        _action();
    }
}

I hope this will give you the idea.

I've just had this same issue with Ionic.

It turns out nothing was wrong with my code, I simply had to quit the ionic serve session and run ionic serve again.

After going back into the app, my states worked fine.

I would also suggest pressing save on your app.js file a few times if you are running gulp, to make sure everything gets re-compiled.

Try to replace the

padding: 2px 30px 2px 2px;

with

padding: 2px 2px 2px 2px;

It should work.

Just to add some diversity with regex:

import re

if any(re.findall(r'a|b|c', str, re.IGNORECASE)):
    print 'possible matches thanks to regex'
else:
    print 'no matches'

or if your list is too long - any(re.findall(r'|'.join(a), str, re.IGNORECASE))

The simplest way to do that is using plain HTML.

You can use one of these ways:

<embed type="text/html" src="header.html">

or:

<object name="foo" type="text/html" data="header.html"></object>

Have a look at System.currentTimeMillis().

I think you should re-format your code a bit:

#!/bin/bash
if [ ! -d /home/mlzboy/b2c2/shared/db ]; then
    mkdir -p /home/mlzboy/b2c2/shared/db;
fi;

With the global configuration that you have defined for the exec-maven-plugin:

<plugin>
  <groupId>org.codehaus.mojo</groupId>
  <artifactId>exec-maven-plugin</artifactId>
  <version>1.4.0</version>
  <configuration>
    <mainClass>org.dhappy.test.NeoTraverse</mainClass>
  </configuration>
</plugin>

invoking mvn exec:java on the command line will invoke the plugin which is configured to execute the class org.dhappy.test.NeoTraverse.

So, to trigger the plugin from the command line, just run:

mvn exec:java

Now, if you want to execute the exec:java goal as part of your standard build, you'll need to bind the goal to a particular phase of the default lifecycle. To do this, declare the phase to which you want to bind the goal in the execution element:

<plugin>
  <groupId>org.codehaus.mojo</groupId>
  <artifactId>exec-maven-plugin</artifactId>
  <version>1.4</version>
  <executions>
    <execution>
      <id>my-execution</id>
      <phase>package</phase>
      <goals>
        <goal>java</goal>
      </goals>
    </execution>
  </executions>
  <configuration>
    <mainClass>org.dhappy.test.NeoTraverse</mainClass>
  </configuration>
</plugin>

With this example, your class would be executed during the package phase. This is just an example, adapt it to suit your needs. Works also with plugin version 1.1.

You can convert hex to RGB:

string ccode = "#00FFFF00";
int argb = Int32.Parse(ccode.Replace("#", ""), NumberStyles.HexNumber);
Color clr = Color.FromArgb(argb);

This is a method of the java.awt.Component class. It is used to set the position and size of a component:

setBounds

public void setBounds(int x,
                  int y,
                  int width,
                  int height) 

Moves and resizes this component. The new location of the top-left corner is specified by x and y, and the new size is specified by width and height. Parameters:

• x - the new x-coordinate of this component
• y - the new y-coordinate of this component
• width - the new width of this component
• height - the new height of this component

x and y as above correspond to the upper left corner in most (all?) cases.

It is a shortcut for setLocation and setSize.

This generally only works if the layout/layout manager are non-existent, i.e. null.

I found that word-wrap: anywhere worked (as opposed to word-wrap: break-word mentioned in another answer).

Set a reference to MS Scripting runtime ('Microsoft Scripting Runtime'). As per @regjo's comment, go to Tools->References and tick the box for 'Microsoft Scripting Runtime'.

Create a dictionary instance using the code below:

Set dict = CreateObject("Scripting.Dictionary")

or

Dim dict As New Scripting.Dictionary 

Example of use:

If Not dict.Exists(key) Then 
    dict.Add key, value
End If 

Don't forget to set the dictionary to Nothing when you have finished using it.

Set dict = Nothing 

There are two ways we can convert String to InputStream in Java,

1. Using ByteArrayInputStream

Example :-

String str = "String contents";
InputStream is = new ByteArrayInputStream(str.getBytes(StandardCharsets.UTF_8));

2. Using Apache Commons IO

Example:-

String str = "String contents"
InputStream is = IOUtils.toInputStream(str, StandardCharsets.UTF_8);

As mentioned in the previous answers the difficulty in converting json to csv is because a json file can contain nested dictionaries and therefore be a multidimensional data structure verses a csv which is a 2D data structure. However, a good way to turn a multidimensional structure to a csv is to have multiple csvs that tie together with primary keys.

In your example, the first csv output has the columns "pk","model","fields" as your columns. Values for "pk", and "model" are easy to get but because the "fields" column contains a dictionary, it should be its own csv and because "codename" appears to the be the primary key, you can use as the input for "fields" to complete the first csv. The second csv contains the dictionary from the "fields" column with codename as the the primary key that can be used to tie the 2 csvs together.

Here is a solution for your json file which converts a nested dictionaries to 2 csvs.

import csv
import json

def readAndWrite(inputFileName, primaryKey=""):
    input = open(inputFileName+".json")
    data = json.load(input)
    input.close()

    header = set()

    if primaryKey != "":
        outputFileName = inputFileName+"-"+primaryKey
        if inputFileName == "data":
            for i in data:
                for j in i["fields"].keys():
                    if j not in header:
                        header.add(j)
    else:
        outputFileName = inputFileName
        for i in data:
            for j in i.keys():
                if j not in header:
                    header.add(j)

    with open(outputFileName+".csv", 'wb') as output_file:
        fieldnames = list(header)
        writer = csv.DictWriter(output_file, fieldnames, delimiter=',', quotechar='"')
        writer.writeheader()
        for x in data:
            row_value = {}
            if primaryKey == "":
                for y in x.keys():
                    yValue = x.get(y)
                    if type(yValue) == int or type(yValue) == bool or type(yValue) == float or type(yValue) == list:
                        row_value[y] = str(yValue).encode('utf8')
                    elif type(yValue) != dict:
                        row_value[y] = yValue.encode('utf8')
                    else:
                        if inputFileName == "data":
                            row_value[y] = yValue["codename"].encode('utf8')
                            readAndWrite(inputFileName, primaryKey="codename")
                writer.writerow(row_value)
            elif primaryKey == "codename":
                for y in x["fields"].keys():
                    yValue = x["fields"].get(y)
                    if type(yValue) == int or type(yValue) == bool or type(yValue) == float or type(yValue) == list:
                        row_value[y] = str(yValue).encode('utf8')
                    elif type(yValue) != dict:
                        row_value[y] = yValue.encode('utf8')
                writer.writerow(row_value)

readAndWrite("data")

Sorting by C and D needs to be put into number form for the corresponding column, ie 3 and 4, respectively. Eg Order By 2 asc")

I'd just make a little function for that. Toss in the two values you need to know the difference between and have it subtract the smaller from the larger value. Something like:

CREATE FUNCTION [dbo].[NumDifference] 
    (   @p1 FLOAT,
        @p2 FLOAT )
RETURNS FLOAT
AS
BEGIN
    DECLARE @Diff FLOAT
    IF @p1 > @p2 SET @Diff = @p1 - @p2 ELSE SET @Diff = @p2 - @p1
    RETURN @Diff
END

In a query to get the difference between column a and b:

SELECT a, b, dbo.NumDifference(a, b) FROM YourTable

Windows PowerShell provides two mechanisms for reporting errors: one mechanism for terminating errors and another mechanism for non-terminating errors.

Internal CmdLets code can call a ThrowTerminatingError method when an error occurs that does not or should not allow the cmdlet to continue to process its input objects. The script writter can them use exception to catch these error.

EX :

try
{
  Your database code
}
catch
{
  Error reporting/logging
}

Internal CmdLets code can call a WriteError method to report non-terminating errors when the cmdlet can continue processing the input objects. The script writer can then use -ErrorAction option to hide the messages, or use the $ErrorActionPreference to setup the entire script behaviour.

From at least, the 2.0 version, Spring-Data-Jpa modified findOne().
Now, findOne() has neither the same signature nor the same behavior.
Previously, it was defined in the CrudRepository interface as:

T findOne(ID primaryKey);

Now, the single findOne() method that you will find in CrudRepository is the one defined in the QueryByExampleExecutor interface as:

<S extends T> Optional<S> findOne(Example<S> example);

That is implemented finally by SimpleJpaRepository, the default implementation of the CrudRepository interface.
This method is a query by example search and you don't want that as a replacement.

In fact, the method with the same behavior is still there in the new API, but the method name has changed.
It was renamed from findOne() to findById() in the CrudRepository interface :

Optional<T> findById(ID id); 

Now it returns an Optional, which is not so bad to prevent NullPointerException.

So, the actual method to invoke is now Optional<T> findById(ID id).

How to use that?
Learning Optional usage. Here's important information about its specification:

A container object which may or may not contain a non-null value. If a value is present, isPresent() will return true and get() will return the value.

Additional methods that depend on the presence or absence of a contained value are provided, such as orElse() (return a default value if value not present) and ifPresent() (execute a block of code if the value is present).

Some hints on how to use Optional with Optional<T> findById(ID id).

Generally, as you look for an entity by id, you want to return it or make a particular processing if that is not retrieved.

Here are three classical usage examples.

1. Suppose that if the entity is found you want to get it otherwise you want to get a default value.

You could write :

Foo foo = repository.findById(id)
                    .orElse(new Foo());

or get a null default value if it makes sense (same behavior as before the API change) :

Foo foo = repository.findById(id)
                    .orElse(null);

2. Suppose that if the entity is found you want to return it, else you want to throw an exception.

You could write :

return repository.findById(id)
        .orElseThrow(() -> new EntityNotFoundException(id));

3. Suppose you want to apply a different processing according to if the entity is found or not (without necessarily throwing an exception).

You could write :

Optional<Foo> fooOptional = fooRepository.findById(id);
if (fooOptional.isPresent()) {
    Foo foo = fooOptional.get();
    // processing with foo ...
} else {
    // alternative processing....
}

You can try something like this:

class mylist(list):

    def __sub__(self, b):
        result = self[:]
        b = b[:]
        while b:
            try:
                result.remove(b.pop())
            except ValueError:
                raise Exception("Not all elements found during subtraction")
        return result


a = mylist([0, 1, 2, 1, 0] )
b = mylist([0, 1, 1])

>>> a - b
[2, 0]

You have to define what [1, 2, 3] - [5, 6] should output though, I guess you want [1, 2, 3] thats why I ignore the ValueError.

Edit: Now I see you wanted an exception if a does not contain all elements, added it instead of passing the ValueError.

I put the following in my .gvimrc file, which searches up the tree from any point for a tags file when gvim starts:

function SetTags()
    let curdir = getcwd()

    while !filereadable("tags") && getcwd() != "/"
        cd ..
    endwhile

    if filereadable("tags")
        execute "set tags=" . getcwd() . "/tags"
    endif

    execute "cd " . curdir
endfunction

call SetTags()

I then periodically regenerate a tags file at the top of my source tree with a script that looks like:

#!/bin/bash

find . -regex ".*\.\(c\|h\|hpp\|cc\|cpp\)" -print | ctags --totals --recurse --extra="+qf" --fields="+i" -L -

Base on this.

Step by step:

• On your local workstation: On Sublime Text 3, open Package Manager (Ctrl-Shift-P on Linux/Win, Cmd-Shift-P on Mac, Install Package), and search for rsub
• On your local workstation: Add RemoteForward 52698 127.0.0.1:52698 to your .ssh/config file, or -R 52698:localhost:52698 if you prefer command line

• On your remote server:

  sudo wget -O /usr/local/bin/rsub https://raw.github.com/aurora/rmate/master/rmate
  sudo chmod a+x /usr/local/bin/rsub
  

Just keep your ST3 editor open, and you can easily edit remote files with

rsub myfile.txt

EDIT: if you get "no such file or directory", it's because your /usr/local/bin is not in your PATH. Just add the directory to your path:

echo "export PATH=\"$PATH:/usr/local/bin\"" >> $HOME/.bashrc

Now just log off, log back in, and you'll be all set.

same as Igor but should work without line 2:

RewriteEngine On
RewriteCond %{REQUEST_FILENAME} !-f
RewriteRule ^([^\.]+)$ $1.php [NC,L]

Try this:

var d = new Date(),
    minutes = d.getMinutes().toString().length == 1 ? '0'+d.getMinutes() : d.getMinutes(),
    hours = d.getHours().toString().length == 1 ? '0'+d.getHours() : d.getHours(),
    ampm = d.getHours() >= 12 ? 'pm' : 'am',
    months = ['Jan','Feb','Mar','Apr','May','Jun','Jul','Aug','Sep','Oct','Nov','Dec'],
    days = ['Sun','Mon','Tue','Wed','Thu','Fri','Sat'];
return days[d.getDay()]+' '+months[d.getMonth()]+' '+d.getDate()+' '+d.getFullYear()+' '+hours+':'+minutes+ampm;

If someone is looking for installing Go 1.8 the follow this:

sudo add-apt-repository ppa:longsleep/golang-backports
sudo apt-get update
sudo apt-get install golang-go

And then install go

sudo apt-get install golang-1.8-go

Another method that has not been mentioned yet is std::vector.

std::vector<std::string> line;

while(file >> mystr)
{
   line.push_back(mystr);
}

Then you can simply iterate over the vector and modify/extract what you need/

As a workaround, you could use the timestamp (old and new) for checking though, that one is not updated when there are no changes to the row. (Possibly that is the source for confusion? Because that one is also called 'on update' but is not executed when no change occurs) Changes within one second will then not execute that part of the trigger, but in some cases that could be fine (like when you have an application that rejects fast changes anyway.)

For example, rather than

IF NEW.a <> OLD.a or NEW.b <> OLD.b /* etc, all the way to NEW.z <> OLD.z */ 
THEN  
  INSERT INTO bar (a, b) VALUES(NEW.a, NEW.b) ;
END IF

you could use

IF NEW.ts <> OLD.ts 
THEN  
  INSERT INTO bar (a, b) VALUES(NEW.a, NEW.b) ;
END IF

Then you don't have to change your trigger every time you update the scheme (the issue you mentioned in the question.)

EDIT: Added full example

create table foo (a INT, b INT, ts TIMESTAMP);
create table bar (a INT, b INT);

INSERT INTO foo (a,b) VALUES(1,1);
INSERT INTO foo (a,b) VALUES(2,2);
INSERT INTO foo (a,b) VALUES(3,3);

DELIMITER ///

CREATE TRIGGER ins_sum AFTER UPDATE ON foo

    BEGIN
        IF NEW.ts <> OLD.ts THEN  
            INSERT INTO bar (a, b) VALUES(NEW.a, NEW.b);
        END IF;
    END;

It is working because of mysql's behavior on handling timestamps. The time stamp is only updated if a change occured in the updates.

You can easily do this via ant. Here is a build.xml file for doing this

 <project name="genTestReport" default="gen" basedir=".">
        <description>
                Generate the HTML report from JUnit XML files
        </description>

        <target name="gen">
                <property name="genReportDir" location="${basedir}/unitTestReports"/>
                <delete dir="${genReportDir}"/>
                <mkdir dir="${genReportDir}"/>
                <junitreport todir="${basedir}/unitTestReports">
                        <fileset dir="${basedir}">
                                <include name="**/TEST-*.xml"/>
                        </fileset>
                        <report format="frames" todir="${genReportDir}/html"/>
                </junitreport>
        </target>
</project>

This will find files with the format TEST-*.xml and generate reports into a folder named unitTestReports.

To run this (assuming the above file is called buildTestReports.xml) run the following command in the terminal:

ant -buildfile buildTestReports.xml

Since you are using an INNER JOIN you can just put the conditions in the WHERE clause, like this:

SELECT 
    p1.kArtikel, 
    p1.cName, 
    p1.cKurzBeschreibung, 
    p1.dLetzteAktualisierung, 
    p1.dErstellt, 
    p1.cSeo,
    p2.kartikelpict,
    p2.nNr,
    p2.cPfad  
FROM 
    tartikel AS p1 INNER JOIN tartikelpict AS p2 
    ON p1.kArtikel = p2.kArtikel
WHERE
  DATE(dErstellt) > (NOW() - INTERVAL 7 DAY)
  AND p2.nNr = 1
ORDER BY 
  p1.kArtikel DESC
LIMIT
    100;

word-wrap: break-word;

worked for me.

Console Application is an application (.exe), not a Library (.dll). To make a library, create a new project, select "Class Library" in type of project, then copy the logic of your first code into this new project.

Or you can edit the Project Properties and select Class Library instead of Console Application in Output type.

As some code can be "console" dependant, I think first solution is better if you check your logic when you copy it.

In Code behind you can achieve it only by doing this.

 private void Window_Loaded(object sender, RoutedEventArgs e)
        {
            txtIndex.Focusable = true;
            txtIndex.Focus();
        }

Note: It wont work before window is loaded

String[] result = "hi i'm paul".split("\\s+"); to split across one or more cases.

Or you could take a look at Apache Common StringUtils. It has StringUtils.split(String str) method that splits string using white space as delimiter. It also has other useful utility methods

If you change the format of the cells to General then this will show the date value of a cell as behind the scenes Excel saves a date as the number of days since 01/01/1900

If your date is text and you need to convert it then DATEVALUE will do this:

Some programs can't process output stream very well, using pipe to Out-Null may not block it.
And Start-Process needs the -ArgumentList switch to pass arguments, not so convenient.
There is also another approach.

$exitCode = [Diagnostics.Process]::Start(<process>,<arguments>).WaitForExit(<timeout>)

The destructor for the object of class A will only be called if delete is called for that object. Make sure to delete that pointer in the destructor of class B.

For a little more information on what happens when delete is called on an object, see: http://www.parashift.com/c++-faq-lite/freestore-mgmt.html#faq-16.9

Here's an example of going from a list of strings, to a single string, back to a list of strings.

Compiling:

$ javac test.java
$ java test

Running:

    Initial list:

        "abc"
        "def"
        "ghi"
        "jkl"
        "mno"

    As single string:

        "[abc, def, ghi, jkl, mno]"

    Reconstituted list:

        "abc"
        "def"
        "ghi"
        "jkl"
        "mno"

Source code:

import java.util.*;
public class test {

    public static void main(String[] args) {
        List<String> listOfStrings= new ArrayList<>();
        listOfStrings.add("abc");
        listOfStrings.add("def");
        listOfStrings.add("ghi");
        listOfStrings.add("jkl");
        listOfStrings.add("mno");

        show("\nInitial list:", listOfStrings);

        String singleString = listOfStrings.toString();

        show("As single string:", singleString);

        List<String> reconstitutedList = Arrays.asList(
             singleString.substring(0, singleString.length() - 1)
                  .substring(1).split("[\\s,]+"));

        show("Reconstituted list:", reconstitutedList);
    }

    public static void show(String title, Object operand) {
        System.out.println(title + "\n");
        if (operand instanceof String) {
            System.out.println("    \"" + operand + "\"");
        } else {
            for (String string : (List<String>)operand)
                System.out.println("    \"" + string + "\"");
        }
        System.out.println("\n");
    }
}

Add commons-collections4-x.x.jar file in your build path and try it again. It will work.

You can download it from https://mvnrepository.com/artifact/org.apache.commons/commons-collections4/4.0

Use .apply() to have the same access to arguments in function b, like this:

function a(){
    b.apply(null, arguments);
}
function b(){
   alert(arguments); //arguments[0] = 1, etc
}
a(1,2,3);?

You can test it out here.

As for me, the default mode of id_rsa is 600, which means readable and writable.

After I push this file to a git repo and pull it from another pc, sometimes the mode of the private key file becomes -rw-r--r--.

When I pull the repo with ssh after specify the private key file, it failed and prompted warnings the same with you. Following is my script.

ssh-agent bash -c "ssh-add $PATH_OF_RSA/id_rsa; \
git pull [email protected]:someone/somerepo.git "

I fix this problem just by changing the mode to 600.

chmod 600 $PATH_TO_RSA/id_rsa

Sometimes it is possible to solve it in the model like this: Suppose you have 3 boolean properties OptionA, OptionB, OptionC.

XAML:

<RadioButton IsChecked="{Binding OptionA}"/>
<RadioButton IsChecked="{Binding OptionB}"/>
<RadioButton IsChecked="{Binding OptionC}"/>

CODE:

private bool _optionA;
public bool OptionA
{
    get { return _optionA; }
    set
    {
        _optionA = value;
        if( _optionA )
        {
             this.OptionB= false;
             this.OptionC = false;
        }
    }
}

private bool _optionB;
public bool OptionB
{
    get { return _optionB; }
    set
    {
        _optionB = value;
        if( _optionB )
        {
            this.OptionA= false;
            this.OptionC = false;
        }
    }
}

private bool _optionC;
public bool OptionC
{
    get { return _optionC; }
    set
    {
        _optionC = value;
        if( _optionC )
        {
            this.OptionA= false;
            this.OptionB = false;
        }
    }
}

You get the idea. Not the cleanest thing, but easy.

Try this:

1. Create a folder named "--F" under currdir ..(or link another folder there renamed to "--F" ie double-minus-F.
2. #> grep -i --exclude-dir="\-\-F" "pattern" *

This error can be caused by an unclosed set of brackets.

int main {
  doSomething {}
  doSomething else {
}

Not so easy to spot, even in this 4 line example.

This error, in a 150 line main function, caused the bewildering error: "static declaration of ‘savePair’ follows non-static declaration". There was nothing wrong with my definition of function savePair, it was that unclosed bracket.

small remark: I am using modules in webbased application (asp.net). I need to remember that everything I store in the variables on the module are seen by everyone in the application, read website. Not only in my session. If i try to add up a calculation in my session I need to make an array to filter the numbers for my session and for others. Modules is a great way to work but need concentration on how to use it.

To help against mistakes: classes are send to the

CarbageCollector

when the page is finished. My modules stay alive (as long as the application is not ended or restarted) and I can reuse the data in it. I use this to save data that sometimes is lost because of the sessionhandling by IIS.

IIS Form auth

and

IIS_session

are not in sync, and with my module I pull back data that went over de cliff.

I was hunting around for an answer to this question. I found this helpful. The pattern wasn't apparent in the documentation for with_items.

I was facing the same issue but it was not a permission issue.

When you are doing git clone it will create try to create replica of the respository structure.

When its trying to create the folder/directory with same name and path in your local os process is not allowing to do so and hence the error. There was "background" java process running in Task-manager which was accessing the resource of the directory(folder) and hence it was showing as permission denied for git operations. I have killed those process and that solved my problem. Cheers!!

The error is caused because ElementTree did not expect to find non-ASCII strings set the XML when trying to write it out. You should use Unicode strings for non-ASCII instead. Unicode strings can be made either by using the u prefix on strings, i.e. u'€' or by decoding a string with mystr.decode('utf-8') using the appropriate encoding.

The best practice is to decode all text data as it's read, rather than decoding mid-program. The io module provides an open() method which decodes text data to Unicode strings as it's read.

ElementTree will be much happier with Unicodes and will properly encode it correctly when using the ET.write() method.

Also, for best compatibility and readability, ensure that ET encodes to UTF-8 during write() and adds the relevant header.

Presuming your input file is UTF-8 encoded (0xC2 is common UTF-8 lead byte), putting everything together, and using the with statement, your code should look like:

with io.open('myText.txt', "r", encoding='utf-8') as f:
    data = f.read()

root = ET.Element("add")
doc = ET.SubElement(root, "doc")

field = ET.SubElement(doc, "field")
field.set("name", "text")
field.text = data

tree = ET.ElementTree(root)
tree.write("output.xml", encoding='utf-8', xml_declaration=True)

Output:

<?xml version='1.0' encoding='utf-8'?>
<add><doc><field name="text">data€</field></doc></add>

You use something like

from flask import send_file

@app.route('/get_image')
def get_image():
    if request.args.get('type') == '1':
       filename = 'ok.gif'
    else:
       filename = 'error.gif'
    return send_file(filename, mimetype='image/gif')

to send back ok.gif or error.gif, depending on the type query parameter. See the documentation for the send_file function and the request object for more information.

Actually, to query the team_name, just add it in brackets to the last line. Apart from that, it seems to work on Python 2.7.3 on command line.

plt.close('all') will close all fiures

Found here.

Remember that plt.show() is a blocking function, so in the example code you used above, plt.close() isn't being executed until the window is closed, which makes it redundant.

You can use plt.ion() at the beginning of your code to make it non-blocking, although this has other implications.

EXAMPLE

After our discussion in the comments, I've put together a bit of an example just to demonstrate how the plot functionality can be used.

Below I create a plot:

fig = plt.figure(figsize=plt.figaspect(0.75))
ax = fig.add_subplot(1, 1, 1)
....
par_plot, = plot(x_data,y_data, lw=2, color='red')

In this case, ax above is a handle to a pair of axes. Whenever I want to do something to these axes, I can change my current set of axes to this particular set by calling axes(ax).

par_plot is a handle to the line2D instance. This is called an artist. If I want to change a property of the line, like change the ydata, I can do so by referring to this handle.

I can also create a slider widget by doing the following:

axsliderA = axes([0.12, 0.85, 0.16, 0.075])
sA = Slider(axsliderA, 'A', -1, 1.0, valinit=0.5)
sA.on_changed(update)

The first line creates a new axes for the slider (called axsliderA), the second line creates a slider instance sA which is placed in the axes, and the third line specifies a function to call when the slider value changes (update).

My update function could look something like this:

def update(val):
    A = sA.val
    B = sB.val
    C = sC.val
    y_data = A*x_data*x_data + B*x_data + C
    par_plot.set_ydata(y_data)
    draw()

The par_plot.set_ydata(y_data) changes the ydata property of the Line2D object with the handle par_plot.

The draw() function updates the current set of axes.

Putting it all together:

from pylab import *
import matplotlib.pyplot as plt
import numpy

def update(val):
    A = sA.val
    B = sB.val
    C = sC.val
    y_data = A*x_data*x_data + B*x_data + C
    par_plot.set_ydata(y_data)
    draw()


x_data = numpy.arange(-100,100,0.1);

fig = plt.figure(figsize=plt.figaspect(0.75))
ax = fig.add_subplot(1, 1, 1)
subplots_adjust(top=0.8)

ax.set_xlim(-100, 100);
ax.set_ylim(-100, 100);
ax.set_xlabel('X')
ax.set_ylabel('Y')

axsliderA = axes([0.12, 0.85, 0.16, 0.075])
sA = Slider(axsliderA, 'A', -1, 1.0, valinit=0.5)
sA.on_changed(update)

axsliderB = axes([0.43, 0.85, 0.16, 0.075])
sB = Slider(axsliderB, 'B', -30, 30.0, valinit=2)
sB.on_changed(update)

axsliderC = axes([0.74, 0.85, 0.16, 0.075])
sC = Slider(axsliderC, 'C', -30, 30.0, valinit=1)
sC.on_changed(update)

axes(ax)
A = 1;
B = 2;
C = 1;
y_data = A*x_data*x_data + B*x_data + C;

par_plot, = plot(x_data,y_data, lw=2, color='red')

show()

A note about the above: When I run the application, the code runs sequentially right through (it stores the update function in memory, I think), until it hits show(), which is blocking. When you make a change to one of the sliders, it runs the update function from memory (I think?).

This is the reason why show() is implemented in the way it is, so that you can change values in the background by using functions to process the data.

I'm a bit confused by the quotes, however, below should work for you:

SELECT "Gc_Staff_Number",
       "Start_Date", x.end_date
FROM   "Employment_History" eh,
(SELECT "End_Date"
        FROM   "Employment_History"
        WHERE  "Current_Flag" != 'Y'
               AND ROWNUM = 1
               AND "Employee_Number" = eh.Employee_Number
        ORDER  BY "End_Date" ASC) x
WHERE  "Current_Flag" = 'Y'

The only thing that worked for me (under windows) was to reopen the IDE as administrator. All worked smoothly after that.

You should be able to use the /quiet or /qn options with msiexec to perform a silent install.

MSI packages export public properties, which you can set with the PROPERTY=value syntax on the end of the msiexec parameters.

For example, this command installs a package with no UI and no reboot, with a log and two properties:

msiexec /i c:\path\to\package.msi /quiet /qn /norestart /log c:\path\to\install.log PROPERTY1=value1 PROPERTY2=value2

You can read the options for msiexec by just running it with no options from Start -> Run.

using System;
using System.Data;
using System.Data.SqlClient;

namespace InsertingData
{
    class sqlinsertdata
    {
        static void Main(string[] args)
        {
            try
            { 
            SqlConnection conn = new SqlConnection("Data source=USER-PC; Database=Emp123;User Id=sa;Password=sa123");
            conn.Open();
                SqlCommand cmd = new SqlCommand("insert into <Table Name>values(1,'nagendra',10000);",conn);
                cmd.ExecuteNonQuery();
                Console.WriteLine("Inserting Data Successfully");
                conn.Close();
        }
            catch(Exception e)
            {
                Console.WriteLine("Exception Occre while creating table:" + e.Message + "\t"  + e.GetType());
            }
            Console.ReadKey();

    }
    }
}

The direct way of doing this is to create triggers on tables. Set some conditions or mapping methods. When update or delete occurs, it will insert into 'change' table automatically.

But the biggest part is what if we got lots columns and lots of table. We have to type every column's name of every table. Obviously, It's waste of time.

To handle this more gorgeously, we can create some procedures or functions to retrieve name of columns.

We can also use 3rd-part tool simply to do this. Here, I write a java program Mysql Tracker

Try

set JAVA_OPTS=%JAVA_OPTS% -Xms512M -Xmx1024M

I figured it out and the simplest way to do this ist just copy and past the CDN of bootstrap link that can be found in https://www.bootstrapcdn.com/ and the Jquery CDN Scripts that can be found here https://code.jquery.com/ and after you copy the links, the bootstrap links paste on the head of HTML and the Jquery Script paste in body of HTML like the example below:

    <!DOCTYPE html>
    <html>
      <head>

        <title>Purrfect Match Landing Page</title>
        <!-- Latest compiled and minified CSS -->

For me works perfect hope it works also for you :)

@Anothen and @Number8 - The Vector class is not available in Silverlight, so to make it work we just need to keep a record of the last position sighted the last time the MouseMove event was called, and compare the two points to find the difference; then adjust the transform.

XAML:

    <Border Name="viewboxBackground" Background="Black">
            <Viewbox Name="viewboxMain">
                <!--contents go here-->
            </Viewbox>
    </Border>  

Code-behind:

    public Point _mouseClickPos;
    public bool bMoving;


    public MainPage()
    {
        InitializeComponent();
        viewboxMain.RenderTransform = new CompositeTransform();
    }

    void MouseMoveHandler(object sender, MouseEventArgs e)
    {

        if (bMoving)
        {
            //get current transform
            CompositeTransform transform = viewboxMain.RenderTransform as CompositeTransform;

            Point currentPos = e.GetPosition(viewboxBackground);
            transform.TranslateX += (currentPos.X - _mouseClickPos.X) ;
            transform.TranslateY += (currentPos.Y - _mouseClickPos.Y) ;

            viewboxMain.RenderTransform = transform;

            _mouseClickPos = currentPos;
        }            
    }

    void MouseClickHandler(object sender, MouseButtonEventArgs e)
    {
        _mouseClickPos = e.GetPosition(viewboxBackground);
        bMoving = true;
    }

    void MouseReleaseHandler(object sender, MouseButtonEventArgs e)
    {
        bMoving = false;
    }

Also note that you don't need a TransformGroup or collection to implement pan and zoom; instead, a CompositeTransform will do the trick with less hassle.

I'm pretty sure this is really inefficient in terms of resource usage, but at least it works :)

The best way to put is that hg forget is identical to hg remove except that it leaves the files behind in your working copy. The files are left behind as untracked files and can now optionally be ignored with a pattern in .hgignore.

In other words, I cannot tell if you used hg forget or hg remove when I pull from you. A file that you ran hg forget on will be deleted when I update to that changeset — just as if you had used hg remove instead.

I've seen this error when an existing table in the database doesn't appropriately map to a code first model. Specifically I had a char(1) in the database table and a char in C#. Changing the model to a string resolved the problem.

git config user.email "[email protected]"

Doing that one inside a repo will set the configuration on THAT repo, and not globally.

Seems like that's pretty much what you're after, unless I'm misreading you.

You can add property to your model as follows:

    public string DetailsClass { get { return Details.Count > 0 ? "show" : "hide" } }

and then your view will be simpler and will contain no logic at all:

    <div class="details @Model.DetailsClass"/>

This will work even with many classes and will not render class if it is null:

    <div class="@Model.Class1 @Model.Class2"/>

with 2 not null properties will render:

    <div class="class1 class2"/>

if class1 is null

    <div class=" class2"/>

import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.web.client.RestTemplate;

@Configuration
public class RestTemplateClient {
    @Bean
    public RestTemplate restTemplate() {
        return new RestTemplate();
    }
}

This is a personal and situational choice. The important thing to remember is that the empty string and the number zero are conceptually distinct from null.

In the case of a count you probably always want some valid number (unless the count is unknown or undefined), but in the case of strings, who knows? The empty string could mean something in your application. Or maybe it doesn't. That's up to you to decide.

The double '%' works also in ".Format(…). Example (with iDrawApertureMask == 87, fCornerRadMask == 0.05): csCurrentLine.Format("\%ADD%2d%C,%6.4f*\%",iDrawApertureMask,fCornerRadMask) ; gives the desired and expected value of (string contents in) csCurrentLine; "%ADD87C, 0.0500*%"

I just had this problem too. Apparently I had set the JRE to 1.5 instead of 1.6 in my build path.

In addition to the accepted answer you can use this if you want to group by multiple columns:

<ul ng-repeat="(key, value) in players | groupBy: '[team,name]'">

Regards,

In Javascript the implementation of stacks and queues is as follows:

Stack: A stack is a container of objects that are inserted and removed according to the last-in-first-out (LIFO) principle.

• Push: Method adds one or more elements to the end of an array and returns the new length of the array.
• Pop: Method removes the last element from an array and returns that element.

Queue: A queue is a container of objects (a linear collection) that are inserted and removed according to the first-in-first-out (FIFO) principle.

• Unshift: Method adds one or more elements to the beginning of an array.

• Shift: The method removes the first element from an array.

let stack = [];_x000D_
 stack.push(1);//[1]_x000D_
 stack.push(2);//[1,2]_x000D_
 stack.push(3);//[1,2,3]_x000D_
 _x000D_
console.log('It was inserted 1,2,3 in stack:', ...stack);_x000D_
_x000D_
stack.pop(); //[1,2]_x000D_
console.log('Item 3 was removed:', ...stack);_x000D_
_x000D_
stack.pop(); //[1]_x000D_
console.log('Item 2 was removed:', ...stack);_x000D_
_x000D_
_x000D_
let queue = [];_x000D_
queue.push(1);//[1]_x000D_
queue.push(2);//[1,2]_x000D_
queue.push(3);//[1,2,3]_x000D_
_x000D_
console.log('It was inserted 1,2,3 in queue:', ...queue);_x000D_
_x000D_
queue.shift();// [2,3]_x000D_
console.log('Item 1 was removed:', ...queue);_x000D_
_x000D_
queue.shift();// [3]_x000D_
console.log('Item 2 was removed:', ...queue);

I really like grep() and grepl() for this purpose.

grep() returns a vector of integers, which indicate where matches are.

yo <- c("a", "a", "b", "b", "c", "c")

grep("b", yo)
[1] 3 4

grepl() returns a logical vector, with "TRUE" at the location of matches.

yo <- c("a", "a", "b", "b", "c", "c")

grepl("b", yo)
[1] FALSE FALSE  TRUE  TRUE FALSE FALSE

These functions are case-sensitive.

While there are several excellent answers, ranging from usual suspects to newer solutions, I would like to provide one more to the fray that addresses what you should do when you are working on a solution with multiple projects.

Before I arrived at this solution, I kept looking at bindingInformation in the applicationhost.config of the solution, tirelessly looking for any hint of why things were simply not working.

Turns out, the simple thing that I overlooked was that different projects have individual settings too.

So, besides Project > {Project-Name} Properties... > Web > Start Action on my Backend Project, I also had to Go to Website > Start Options... > Start Action on my Frontend Project. Once there, I selected Don't open a page. Wait for a request from an external application and have been happy ever since!

The general explanation is provided in the link from Dan.

For specific questions your ask :

They can reside on the same machine, even in the same process (JVM for Java). It is a logical distinction (what they do?), not a physical one (where they are?).

Notes

• Currently the last key code is KEYCODE_SYSTEM_NAVIGATION_RIGHT, which is 283 (but check the source code to make sure this is still true). So you could loop through them like this:

  for (int keyCode = 0; keyCode <= 283; keyCode++) {
  
  }
  

• Most input to EditText (or a custom view that accepts keyboard input) from an Input Method Editor (IME) is done using an Input Connection, so many key codes are not sent at all in this case. See this answer.

You can use this

string.strip().split(":")

You can get the values with use of ID. But ID should be Unique.

<body>

<form>
  a: <input type="number" name="a" id="a"><br>
  b: <input type="number" name="b" id="b"><br>

</form>
<script>
  function add() {
    a = $('#a').val();
    b = $('#b').val();
    var sum = a + b;
    alert(sum);
  }
</script>

I had the same problem and solved it by using the default woocommerce hook to display the product image.

while ( $loop->have_posts() ) : $loop->the_post();
   echo woocommerce_get_product_thumbnail('woocommerce_full_size');
endwhile;

Available parameters:

• woocommerce_thumbnail
• woocommerce_full_size

Triple check the name and path of the file. In my case I had something like this content in the target folder:

lib
    foobar.bundle.js
    foobr.css

And this link:

<link rel="stylesheet" href="lib/foobar.css">

I guess that the browser was trying to load the JavaScript file and complaining about its MIME type instead of giving me a file not found error.

It appears the default setting for Adobe Reader X is for the toolbars not to be shown by default unless they are explicitly turned on by the user. And even when I turn them back on during a session, they don't show up automatically next time. As such, I suspect you have a preference set contrary to the default.

The state you desire, with the top and left toolbars not shown, is called "Read Mode". If you right-click on the document itself, and then click "Page Display Preferences" in the context menu that is shown, you'll be presented with the Adobe Reader Preferences dialog. (This is the same dialog you can access by opening the Adobe Reader application, and selecting "Preferences" from the "Edit" menu.) In the list shown in the left-hand column of the Preferences dialog, select "Internet". Finally, on the right, ensure that you have the "Display in Read Mode by default" box checked:

You can also turn off the toolbars temporarily by clicking the button at the right of the top toolbar that depicts arrows pointing to opposing corners:

Finally, if you have "Display in Read Mode by default" turned off, but want to instruct the page you're loading not to display the toolbars (i.e., override the user's current preferences), you can append the following to the URL:

#toolbar=0&navpanes=0

So, for example, the following code will disable both the top toolbar (called "toolbar") and the left-hand toolbar (called "navpane"). However, if the user knows the keyboard combination (F8, and perhaps other methods as well), they will still be able to turn them back on.

string url = @"http://www.domain.com/file.pdf#toolbar=0&navpanes=0";
this._WebBrowser.Navigate(url);

You can read more about the parameters that are available for customizing the way PDF files open here on Adobe's developer website.

You have 2 options here:

1. Assign a default value to each primary constructor parameter:

   data class Activity(
       var updated_on: String = "",
       var tags: List<String> = emptyList(),
       var description: String = "",
       var user_id: List<Int> = emptyList(),
       var status_id: Int = -1,
       var title: String = "",
       var created_at: String = "",
       var data: HashMap<*, *> = hashMapOf<Any, Any>(),
       var id: Int = -1,
       var counts: LinkedTreeMap<*, *> = LinkedTreeMap<Any, Any>()
   ) 
   

2. Declare a secondary constructor that has no parameters:

   data class Activity(
       var updated_on: String,
       var tags: List<String>,
       var description: String,
       var user_id: List<Int>,
       var status_id: Int,
       var title: String,
       var created_at: String,
       var data: HashMap<*, *>,
       var id: Int,
       var counts: LinkedTreeMap<*, *>
   ) {
       constructor() : this("", emptyList(), 
                            "", emptyList(), -1, 
                            "", "", hashMapOf<Any, Any>(), 
                            -1, LinkedTreeMap<Any, Any>()
                            )
   }
   

If you don't rely on copy or equals of the Activity class or don't use the autogenerated data class methods at all you could use regular class like so:

class ActivityDto {
    var updated_on: String = "",
    var tags: List<String> = emptyList(),
    var description: String = "",
    var user_id: List<Int> = emptyList(),
    var status_id: Int = -1,
    var title: String = "",
    var created_at: String = "",
    var data: HashMap<*, *> = hashMapOf<Any, Any>(),
    var id: Int = -1,
    var counts: LinkedTreeMap<*, *> = LinkedTreeMap<Any, Any>()
}

Not every DTO needs to be a data class and vice versa. In fact in my experience I find data classes to be particularly useful in areas that involve some complex business logic.

start "Chrome" "C:\Program Files (x86)\Google\Chrome\Application\chrome.exe" --profile-directory="Profile 2"

start "webpage name" "http://someurl.com/"

start "Chrome" "C:\Program Files (x86)\Google\Chrome\Application\chrome.exe" --profile-directory="Profile 3"

start "webpage name" "http://someurl.com/"

You can use Integer.parseInt() or Integer.valueOf() to get the integer from the string, and catch the exception if it is not a parsable int. You want to be sure to catch the NumberFormatException it can throw.

It may be helpful to note that valueOf() will return an Integer object, not the primitive int.

Serialize data:

setcookie('cookie', serialize($info), time()+3600);

Then unserialize data:

$data = unserialize($_COOKIE['cookie'], ["allowed_classes" => false]);

After data, $info and $data will have the same content.

Your stored procedure expects 5 parameters as input

@userID int, 
@userName varchar(50), 
@password nvarchar(50), 
@emailAddress nvarchar(50), 
@preferenceName varchar(20) 

So you should add all 5 parameters to this SP call:

    cmd.CommandText = "SHOWuser";
    cmd.Parameters.AddWithValue("@userID",userID);
    cmd.Parameters.AddWithValue("@userName", userName);
    cmd.Parameters.AddWithValue("@password", password);
    cmd.Parameters.AddWithValue("@emailAddress", emailAddress);
    cmd.Parameters.AddWithValue("@preferenceName", preferences);
    dbcon.Open();

PS: It's not clear what these parameter are for. You don't use these parameters in your SP body so your SP should looks like:

ALTER PROCEDURE [dbo].[SHOWuser] AS BEGIN ..... END

I've just had the same issue with a document loaded from MongoDB using Mongoose.

Turned out that i'm using the property find() to return just one object, so i changed find() to findOne() and everything worked for me.

Solution (if you're using Mongoose): Make sure to return one object only, so you can parse its object.id or it will be treated as an array so you need to acces it like that object[0].id.

This should work for you. It just passes {:value => params[:pid] } to the html_options variable.

<%= f.select :project_id, @project_select, {}, {:value => params[:pid] } %>

A static nested class interacts with the instance members of its outer class (and other classes) just like any other top-level class. In effect, a static nested class is behaviorally a top-level class that has been nested in another top-level class for packaging convenience.

I need to add my 5 cents. I see everybody use [ or [[, but it worth to mention that they are not part of if syntax.

For arithmetic comparisons, use ((...)) instead.

((...)) is an arithmetic command, which returns an exit status of 0 if the expression is nonzero, or 1 if the expression is zero. Also used as a synonym for "let", if side effects (assignments) are needed.

See: ArithmeticExpression

I don't think "have HTTPS connections over proxy servers" means the Man-in-the-Middle attack type of proxy server. I think it's asking whether one can connect to a http proxy server over TLS. And the answer is yes.

Is it possible to have HTTPS connections over proxy servers?

Yes, see my question and answer here. HTTPs proxy server only works in SwitchOmega

If yes, what kind of proxy server allows this?

The kind of proxy server deploys SSL certificates, like how ordinary websites do. But you need a pac file for the brower to configure proxy connection over SSL.

When you want to loop into a multiple dimensions array, you can use foreach like this:

foreach($data as $users){
   foreach($users as $user){
      echo $user['id'].' '.$user['c_name'].' '.$user['seat_no'].'<br/>';
   }
}

Below is an interesting use of the id attribute. It is used within the tag and used to identify the form for elements outside of the boundaries so that they will be included with the other fields within the form.

 <form action="action_page.php" id="form1">
 First name: <input type="text" name="fname"><br>
 <input type="submit" value="Submit">
 </form>

 <p>The "Last name" field below is outside the form element, but still part of the form.</p>
 Last name: <input type="text" name="lname" form="form1">

Another solution but without using ng-click which still works even for other tags than <a>:

<tr [routerLink]="['/about']">

This way you can also pass parameters to your route: https://stackoverflow.com/a/40045556/838494

(This is my first day with angular. Gentle feedback is welcome)

The problem here is that the "on" is applied to all elements that exists AT THE TIME. When you create an element dynamically, you need to run the on again:

$('form').on('submit',doFormStuff);

createNewForm();

// re-attach to all forms
$('form').off('submit').on('submit',doFormStuff);

Since forms usually have names or IDs, you can just attach to the new form as well. If I'm creating a lot of dynamic stuff, I'll include a setup or bind function:

function bindItems(){
    $('form').off('submit').on('submit',doFormStuff); 
    $('button').off('click').on('click',doButtonStuff);
}   

So then whenever you create something (buttons usually in my case), I just call bindItems to update everything on the page.

createNewButton();
bindItems();

I don't like using 'body' or document elements because with tabs and modals they tend to hang around and do things you don't expect. I always try to be as specific as possible unless its a simple 1 page project.

Add a style with the attribute text-decoration:none;:

There are a number of different ways of doing this.

Inline style:

<a href="xxx.html" style="text-decoration:none;">goto this link</a>

Inline stylesheet:

<html>
<head>
<style type="text/css">
   a {
      text-decoration:none;
   }
</style>
</head>
<body>
<a href="xxx.html">goto this link</a>
</body>
</html>

External stylesheet:

<html>
<head>
<link rel="Stylesheet" href="stylesheet.css" />
</head>
<body>
<a href="xxx.html">goto this link</a>
</body>
</html>

stylesheet.css:

a {
      text-decoration:none;
   }

You need to create a pandas series first. The second step is to convert the pandas series to pandas dataframe.

import pandas as pd
data = {'a': 1, 'b': 2}
pd.Series(data).to_frame()

You can even provide a column name.

pd.Series(data).to_frame('ColumnName')

This is how I do :

<div class="jumbotron" style="background: url(img/bg.jpg) no-repeat center center fixed; -webkit-background-size: cover; -moz-background-size: cover; -o-background-size: cover; background-size: cover;">_x000D_
  <h1>Hello</h1>_x000D_
</div>

You can destroy all things that was created same way except little thing change. For controller,

rails d controller_name (d stands for destroy)

For Model

rails d model_name

you just put d(destroy) instead of g(generate) in your migration.

The solution is that you should uncheck (deactivate) option "Run only if user is logged on".

After that change, it starts to work on my machine.

You can also use DateTime class:

$time1 = new DateTime('09:00:59');
$time2 = new DateTime('09:01:00');
$interval = $time1->diff($time2);
echo $interval->format('%s second(s)');

Result:

1 second(s)

I believe John's answer is correct. For instance, I'm using my laptop through a wifi service run by a conference centre -- I'm pretty sure that there is no way for javascript running within my browser to discover the IP address being used by the service provider. On the other hand, it may be possible to address a suitable external resource from javascript. You can write your own if your own by making an ajax call to a server which can take the IP address from the HTTP headers and return it, or try googling "find my ip". The cleanest solution is probably to capture the information before the page is served and insert it in the html returned to the user. See How to get a viewer's IP address with python? for info on how to capture the information if you are serving the page with python.

There is no way in the C++ language to check whether a variable is initialized or not (although class types with constructors will be initialized automatically).

Instead, what you need to do is provide constructor(s) that initialize your class to a valid state. Static code checkers (and possibly some compilers) can help you find missing variables in constructors. This way you don't have to worry about being in a bogus state and the if checks in your method can go away completely.

string userName;
string userId;
if (HttpContext.Current != null && HttpContext.Current.User != null 
        && HttpContext.Current.User.Identity.Name != null)
{
    userName = HttpContext.Current.User.Identity.Name;
    userId = HttpContext.Current.User.Identity.GetUserId();
}

Or based on Darrel Miller's comment, maybe use this to retrieve the HttpContext first.

// get httpContext
object httpContext;
actionContext.Request.Properties.TryGetValue("MS_HttpContext", out httpContext);

unfortunately, with "mvim -v", ALT plus arrow windows still does not work. I have not found any way to enable it :-(

There is an errno module that defines standard exit codes:

For example, Permission denied is error code 13:

import errno, sys

if can_access_resource():
    do_something()
else:
    sys.exit(errno.EACCES)

The nebula-facet plugin eliminates the boilerplate:

apply plugin: 'nebula.facet'
facets {
    integrationTest {
        parentSourceSet = 'test'
    }
}

For integration tests specifically, even this is done for you, just apply:

apply plugin: 'nebula.integtest'

The Gradle plugin portal links for each are:

1. nebula.facet
2. nebula.integtest

I think you need to set symbreaks = FALSE That should allow for asymmetrical color scales.

You can use the onsubmit function.

If you return false the form won't get submitted. Read up about it here.

$('#myform').submit(function() {
  // your code here
});

For the benefit of others, I though I'd include what I did.

Since you cannot get Visual Studio (2010 in my case) to ignore the LNK4204 warnings, my approach was to give it what it wanted: the pdb files. As I was using open source libraries in my case, I have the code building the pdb files already.

BUT, the default is to name all of the PDF files the same thing: vc100.pdb in my case. As you need a .pdb for each and every .lib, this creates a problem, especially if you are using something like ImageMagik, which creates about 20 static .lib files. You cannot have 20 lib files in one directory (which your application's linker references to link in the libraries from) and have all the 20 .pdb files called the same thing.

My solution was to go and rebuild my static library files, and configure VS2010 to name the .pdb file with respect to the PROJECT. This way, each .lib gets a similarly named .pdb, and you can put all of the LIBs and PDBs in one directory for your project to use.

So for the "Debug" configuraton, I edited:

Properties->Configuration Properties -> C/C++ -> Output Files -> Program Database File Name from

$(IntDir)vc$(PlatformToolsetVersion).pdb

to be the following value:

$(OutDir)vc$(PlatformToolsetVersion)D$(ProjectName).pdb

Now rather than somewhere in the intermediate directory, the .pdb files are written to the output directory, where the .lib files are also being written, AND most importantly, they are named with a suffix of D+project name. This means each library project produduces a project .lib and a project specific .pdb.

I'm now able to copy all of my release .lib files, my debug .lib files and the debug .pdb files into one place on my development system, and the project that uses that 3rd party library in debug mode, has the pdb files it needs in debug mode.

I was having the same issue, I made the table fixed and then specified my td width. If you have th you can do those as well.

table {
    table-layout: fixed;
    word-wrap: break-word;
}

Template:

<td style="width:10%">content</td>

Please use CSS for structuring any layouts.

$app = Get-WmiObject -Class Win32_Product | Where-Object { 
    $_.Name -match "Software Name" 
}

$app = Get-WmiObject -Class Win32_Product `
                     -Filter "Name = 'Software Name'"

The trick is to add environment variables to sudoers file via sudo visudo command and add these lines:

Defaults env_keep += "ftp_proxy http_proxy https_proxy no_proxy"

taken from ArchLinux wiki.

For Ubuntu 14, you need to specify in separate lines as it returns the errors for multi-variable lines:

Defaults  env_keep += "http_proxy"
Defaults  env_keep += "https_proxy"
Defaults  env_keep += "HTTP_PROXY"
Defaults  env_keep += "HTTPS_PROXY"

Replace disabled with readonly="readonly". I think it is the same function.

<input type="text" class="details-dialog" readonly="readonly" style="color: ur color;">

You should be using the strict not equals comparison operator !== so that if the user inputs "null" then you won't get to the else.

Check this example of post the array of different types

function PostArray() {
    var myObj = [
        { 'fstName': 'name 1', 'lastName': 'last name 1', 'age': 32 }
      , { 'fstName': 'name 2', 'lastName': 'last name 1', 'age': 33 }
    ];

    var postData = JSON.stringify({ lst: myObj });
    console.log(postData);

    $.ajax({
        type: "POST",
        url: urlWebMethods + "/getNames",
        data: postData,
        contentType: "application/json; charset=utf-8",
        dataType: "json",
        success: function (response) {
            alert(response.d);
        },
        failure: function (msg) {
            alert(msg.d);
        }
    });
}

If using a WebMethod in C# you can retrieve the data like this

[WebMethod]
    public static string getNames(IEnumerable<object> lst)
    {
        string names = "";
        try
        {
            foreach (object item in lst)
            {
                Type myType = item.GetType();
                IList<PropertyInfo> props = new List<PropertyInfo>(myType.GetProperties());

                foreach (PropertyInfo prop in props)
                {
                    if(prop.Name == "Values")
                    {
                        Dictionary<string, object> dic = item as Dictionary<string, object>;
                        names += dic["fstName"];
                    }
                }
            }
        }
        catch (Exception ex)
        {
             names = "-1";
        }
        return names;
    }

Do you merely want to print the string that way, or do you want that to be the internal representation of the string? If the latter, create it as a raw string by prefixing it with r: r"Hello\tWorld\nHello World".

>>> a = r"Hello\tWorld\nHello World"
>>> a # in the interpreter, this calls repr()
'Hello\\tWorld\\nHello World'
>>> print a
Hello\tWorld\nHello World

Also, \s is not an escape character, except in regular expressions, and then it still has a much different meaning than what you're using it for.

You have endless loop in place:

function save() {
    var filename = id('filename').value;
    var name = id('name').value;
    var text = id('text').value;
    save(filename, name, text);
}

No idea what you're trying to accomplish with that endless loop but first of all get rid of it and see if things are working.

You can use InlineComparer

public class InlineComparer<T> : IEqualityComparer<T>
{
    //private readonly Func<T, T, bool> equalsMethod;
    //private readonly Func<T, int> getHashCodeMethod;
    public Func<T, T, bool> EqualsMethod { get; private set; }
    public Func<T, int> GetHashCodeMethod { get; private set; }

    public InlineComparer(Func<T, T, bool> equals, Func<T, int> hashCode)
    {
        if (equals == null) throw new ArgumentNullException("equals", "Equals parameter is required for all InlineComparer instances");
        EqualsMethod = equals;
        GetHashCodeMethod = hashCode;
    }

    public bool Equals(T x, T y)
    {
        return EqualsMethod(x, y);
    }

    public int GetHashCode(T obj)
    {
        if (GetHashCodeMethod == null) return obj.GetHashCode();
        return GetHashCodeMethod(obj);
    }
}

Usage sample:

  var comparer = new InlineComparer<DetalleLog>((i1, i2) => i1.PeticionEV == i2.PeticionEV && i1.Etiqueta == i2.Etiqueta, i => i.PeticionEV.GetHashCode() + i.Etiqueta.GetHashCode());
  var peticionesEV = listaLogs.Distinct(comparer).ToList();
  Assert.IsNotNull(peticionesEV);
  Assert.AreNotEqual(0, peticionesEV.Count);

To increase the height of TextField Widget just make use of the maxLines: properties that comes with the widget. For Example: TextField( maxLines: 5 ) // it will increase the height and width of the Textfield.

The error probably gives more information like this (although your jar names could be different)

I decided not to use the one imported from spring-boot-starter-data-jpa (the top dependency) through spring-boot-starter and through spring-boot-starter-logging, pom becomes:

Although using File.separator to reference a file name is overkill (for those who imagine far off lands, I imagine their JVM implementation would replace a / with a : just like the windows jvm replaces it with a \).

However, sometimes you are getting the file reference, not creating it, and you need to parse it, and to be able to do that, you need to know the separator on the platform. File.separator helps you do that.

Use Form, not form. The capitalization counts.

Just create an interface that extends DocumentListener and implements all DocumentListener methods:

@FunctionalInterface
public interface SimpleDocumentListener extends DocumentListener {
    void update(DocumentEvent e);

    @Override
    default void insertUpdate(DocumentEvent e) {
        update(e);
    }
    @Override
    default void removeUpdate(DocumentEvent e) {
        update(e);
    }
    @Override
    default void changedUpdate(DocumentEvent e) {
        update(e);
    }
}

and then:

jTextField.getDocument().addDocumentListener(new SimpleDocumentListener() {
    @Override
    public void update(DocumentEvent e) {
        // Your code here
    }
});

or you can even use lambda expression:

jTextField.getDocument().addDocumentListener((SimpleDocumentListener) e -> {
    // Your code here
});

There's another short-cut you can use, although it can be inefficient depending on what's in your class instances.

As everyone has said the problem is that the multiprocessing code has to pickle the things that it sends to the sub-processes it has started, and the pickler doesn't do instance-methods.

However, instead of sending the instance-method, you can send the actual class instance, plus the name of the function to call, to an ordinary function that then uses getattr to call the instance-method, thus creating the bound method in the Pool subprocess. This is similar to defining a __call__ method except that you can call more than one member function.

Stealing @EricH.'s code from his answer and annotating it a bit (I retyped it hence all the name changes and such, for some reason this seemed easier than cut-and-paste :-) ) for illustration of all the magic:

import multiprocessing
import os

def call_it(instance, name, args=(), kwargs=None):
    "indirect caller for instance methods and multiprocessing"
    if kwargs is None:
        kwargs = {}
    return getattr(instance, name)(*args, **kwargs)

class Klass(object):
    def __init__(self, nobj, workers=multiprocessing.cpu_count()):
        print "Constructor (in pid=%d)..." % os.getpid()
        self.count = 1
        pool = multiprocessing.Pool(processes = workers)
        async_results = [pool.apply_async(call_it,
            args = (self, 'process_obj', (i,))) for i in range(nobj)]
        pool.close()
        map(multiprocessing.pool.ApplyResult.wait, async_results)
        lst_results = [r.get() for r in async_results]
        print lst_results

    def __del__(self):
        self.count -= 1
        print "... Destructor (in pid=%d) count=%d" % (os.getpid(), self.count)

    def process_obj(self, index):
        print "object %d" % index
        return "results"

Klass(nobj=8, workers=3)

The output shows that, indeed, the constructor is called once (in the original pid) and the destructor is called 9 times (once for each copy made = 2 or 3 times per pool-worker-process as needed, plus once in the original process). This is often OK, as in this case, since the default pickler makes a copy of the entire instance and (semi-) secretly re-populates it—in this case, doing:

obj = object.__new__(Klass)
obj.__dict__.update({'count':1})

—that's why even though the destructor is called eight times in the three worker processes, it counts down from 1 to 0 each time—but of course you can still get into trouble this way. If necessary, you can provide your own __setstate__:

    def __setstate__(self, adict):
        self.count = adict['count']

in this case for instance.

There is no internal MySQL command to trace this, it's a little too abstract. The file might be in 5 (or more?) locations, and they would all be valid because they load cascading.

• /etc/my.cnf
• /etc/mysql/my.cnf
• $MYSQL_HOME/my.cnf
• [datadir]/my.cnf
• ~/.my.cnf

Those are the default locations MySQL looks at. If it finds more than one, it will load each of them & values override each other (in the listed order, I think). Also, the --defaults-file parameter can override the whole thing, so... basically, it's a huge pain in the butt.

But thanks to it being so confusing, there's a good chance it's just in /etc/my.cnf.

(if you just want to see the values: SHOW VARIABLES, but you'll need the permissions to do so.)

According to Swift 4 Documentation, String values can be added together (or concatenated) with the addition operator (+) to create a new String value:

let string1 = "hello"
let string2 = " there"
var welcome = string1 + string2
// welcome now equals "hello there"

You can also append a String value to an existing String variable with the addition assignment operator (+=):

var instruction = "look over"
instruction += string2
// instruction now equals "look over there"

You can append a Character value to a String variable with the String type’s append() method:

let exclamationMark: Character = "!"
welcome.append(exclamationMark)
// welcome now equals "hello there!"

if you want to set jvm args on eclipse you can use below:

see below two links to accomplish it:

1. eclipse setting to pass jvm args to java
2. eclipse setting to pass jvm args to java and adding to run config on eclipse
   

And for Tomcat you can create a setenv.bat file in bin folder of Tomcat and add below lines to it :

echo "hello im starting setenv"
set CATALINA_OPTS=-DNLP.home=${NLP.home} -Dhostname=${hostname}

Here's how I interpret it:

int *something[n];

Note on precedence: array subscript operator ([]) has higher priority than dereference operator (*).

So, here we will apply the [] before *, making the statement equivalent to:

int *(something[i]);

Note on how a declaration makes sense: int num means num is an int, int *ptr or int (*ptr) means, (value at ptr) is an int, which makes ptr a pointer to int.

This can be read as, (value of the (value at ith index of the something)) is an integer. So, (value at the ith index of something) is an (integer pointer), which makes the something an array of integer pointers.

In the second one,

int (*something)[n];

To make sense out of this statement, you must be familiar with this fact:

Note on pointer representation of array: somethingElse[i] is equivalent to *(somethingElse + i)

So, replacing somethingElse with (*something), we get *(*something + i), which is an integer as per declaration. So, (*something) given us an array, which makes something equivalent to (pointer to an array).

May 2020 Here's a simple solution i found and it will resolve for all of my projects ,on windows if your project is somewhere inside c: directory , create new file .jshintrc and save it in C directory open this .jshintrc file and write { "esversion": 6} and that's it. the warnings should go away , same will work in d directory

yes you can also enable this setting for the specific project only by same creating a .jshintrc file in your project's root and adding { "esversion": 6}

Try this little crumpet:

-(void)saveUserSettings{
NSNumber*   value;

value = [NSNumber numberWithFloat:self.sensativity];
[[NSUserDefaults standardUserDefaults] setObject:value forKey:@"sensativity"];
}
-(void)loadUserSettings{
    NSNumber*   value;
    value = [[NSUserDefaults standardUserDefaults] objectForKey:@"sensativity"];
    if(value == nil){
        self.sensativity = 4.0;
    }else{
        self.sensativity = [value floatValue];
    }
}

Treat everything as an object. Seems to work for me.

This works in Mac as well you can use

df= pd.read_csv('Region_count.csv', encoding ='latin1')

Simply as bellow;

$this->db->get('table_name')->num_rows();

This will get number of rows/records. however you can use search parameters as well;

$this->db->select('col1','col2')->where('col'=>'crieterion')->get('table_name')->num_rows();

However, it should be noted that you will see bad bad errors if applying as below;

$this->db->get('table_name')->result()->num_rows();

our problem was that the hard drive was down to zero space available.

Check out the MSDN article Asynchronous Programming with Async and Await if you can afford to play with new stuff. It was added to .NET 4.5.

Example code snippet from the link (which is itself from this MSDN sample code project):

// Three things to note in the signature: 
//  - The method has an async modifier.  
//  - The return type is Task or Task<T>. (See "Return Types" section.)
//    Here, it is Task<int> because the return statement returns an integer. 
//  - The method name ends in "Async."
async Task<int> AccessTheWebAsync()
{ 
    // You need to add a reference to System.Net.Http to declare client.
    HttpClient client = new HttpClient();

    // GetStringAsync returns a Task<string>. That means that when you await the 
    // task you'll get a string (urlContents).
    Task<string> getStringTask = client.GetStringAsync("http://msdn.microsoft.com");

    // You can do work here that doesn't rely on the string from GetStringAsync.
    DoIndependentWork();

    // The await operator suspends AccessTheWebAsync. 
    //  - AccessTheWebAsync can't continue until getStringTask is complete. 
    //  - Meanwhile, control returns to the caller of AccessTheWebAsync. 
    //  - Control resumes here when getStringTask is complete.  
    //  - The await operator then retrieves the string result from getStringTask. 
    string urlContents = await getStringTask;

    // The return statement specifies an integer result. 
    // Any methods that are awaiting AccessTheWebAsync retrieve the length value. 
    return urlContents.Length;
}

Quoting:

If AccessTheWebAsync doesn't have any work that it can do between calling GetStringAsync and awaiting its completion, you can simplify your code by calling and awaiting in the following single statement.

string urlContents = await client.GetStringAsync();

More details are in the link.

 php artisan migrate:fresh

Should do the job, if you are in development and the desired outcome is to start all over.

In production, that maybe not the desired thing, so you should be adverted. (The migrate:fresh command will drop all tables from the database and then execute the migrate command).

For Ubuntu terminal:

Please follow the steps:

Step-1:

cd ~

Step -2: Run the following commands

sudo apt-get install php5-intl

Step -3: You then need to restart Apache

sudo service apache2 restart

For Windows(XAMPP) :

Find the Php.ini file:

/xampp/php/php.ini

Update the php.ini file with remove (;) semi colon like mentioned below:

;extension=php_intl.dll to extension=php_intl.dll

and save the php.ini file.

After that you need to

Restart the xampp using xampp control.

For Windows 10:

Right-click the taskbar Windows logo, select 'Programs and Features'.

Click 'Turn Windows Features on or off'

In the dialog box that appears, scroll down or resize the window and check the box next to 'Windows Identity Foundation 3.5'

Click OK.

This activates the required DLLs. Apparently Windows 10 keeps all of those features in the windows installation so that it can activate and deactivate them on demand.

Try this:

<form method="post" action="check.php">
    <select name="website_string">
        <option value="" selected="selected"></option>
        <option VALUE="abc"> ABC</option>
        <option VALUE="def"> def</option>
        <option VALUE="hij"> hij</option>
    </select>
    <input TYPE="submit" name="submit" />
</form>

Both your select control and your submit button had the same name attribute, so the last one used was the submit button when you clicked it. All other syntax errors aside.

check.php

<?php
    echo $_POST['website_string'];
?>

Obligatory disclaimer about using raw $_POST data. Sanitize anything you'll actually be using in application logic.

This works for .Net Core. Call on your Soap client:

client.ClientCredentials.ServiceCertificate.SslCertificateAuthentication =
                new X509ServiceCertificateAuthentication()
                {
                    CertificateValidationMode = X509CertificateValidationMode.None,
                    RevocationMode = X509RevocationMode.NoCheck
                };  

I found a solution like this where a word, "Dark", would be shortened to just "D" on a smaller screen width. Basically you just make the font size of the original content 0 and have the shortened form as a pseudo element.

In this example the change happens on hover instead:

span {_x000D_
  font-size: 12px;_x000D_
}_x000D_
_x000D_
span:after {_x000D_
  display: none;_x000D_
  font-size: 12px;_x000D_
  content: 'D';_x000D_
  color: red;_x000D_
}_x000D_
_x000D_
span:hover {_x000D_
  font-size: 0px;_x000D_
}_x000D_
_x000D_
span:hover:after {_x000D_
  display: inline;_x000D_
}

<span>Dark</span>

If you would like to purposely link your project A in Release against another project B in Debug, say to keep the overall performance benefits of your application while debugging, then you will likely hit this error. You can fix this by temporarily modifying the preprocessor flags of project B to disable iterator debugging (and make it match project A):

In Project B's "Debug" properties, Configuration Properties -> C/C++ -> Preprocessor, add the following to Preprocessor Definitions:

_HAS_ITERATOR_DEBUGGING=0;_ITERATOR_DEBUG_LEVEL=0;

Rebuild project B in Debug, then build project A in Release and it should link correctly.

The same way as you'd set the type (number format mask) after writing a value to it:

$objPHPExcel->getActiveSheet()
    ->getStyle('A1')
    ->getNumberFormat()
    ->setFormatCode(
        PHPExcel_Style_NumberFormat::FORMAT_GENERAL
    );

or

$objPHPExcel->getActiveSheet()
    ->getStyle('A1')
    ->getNumberFormat()
    ->setFormatCode(
        PHPExcel_Style_NumberFormat::FORMAT_TEXT
    );

Though "Number" isn't a valid format mask.

You can find a list of pre-defined format masks in Classes/PHPExcel/Style/NumberFormat.php or set the value to any valid Excel number format masking string.

I know this is an oldie but here is a quick way to hide the scroll bar with pure CSS.

Just add

::-webkit-scrollbar {display:none;}

To your id or class of the div you're using the scroll bar with.

Here is a helpful link Custom Scroll Bar in Webkit

In your ipython_config.py file, search for the following lines

# c.InteractiveShellApp.matplotlib = None

and

# c.InteractiveShellApp.pylab = None

and uncomment them. Then, change None to the backend that you're using (I use 'qt4') and save the file. Restart IPython, and matplotlib and pylab should be loaded - you can use the dir() command to verify which modules are in the global namespace.

I have to add to the answer of douglas, you can access the global config, but symfony translates some parameters, for example:

# config.yml
... 
framework:
    session:
        domain: 'localhost'
...

are

$this->container->parameters['session.storage.options']['domain'];

You can use var_dump to search an specified key or value.

for 32 characters:

for(var c = ''; c.length < 32;) c += Math.random().toString(36).substr(2, 1)

You need the link inside to be clickable, meaning it needs a href with some content, and also, close() is a built-in function of window, so you need to change the name of the function to avoid a conflict.

<div id="upbutton"><a href="#" onclick="close2()">click to close</a></div>

Also if you want a real "button" instead of a link, you should use <input type="button"/> or <button/>.

$("#" + $(this).attr("name")).hide();

You can trigger any of the events with a direct call to them, like this:

$(function() {
    $('item').keydown();
    $('item').keypress();
    $('item').keyup();
    $('item').blur();
});

Does that do what you're trying to do?

You should probably also trigger .focus() and potentially .change()

If you want to trigger the key-events with specific keys, you can do so like this:

$(function() {
    var e = $.Event('keypress');
    e.which = 65; // Character 'A'
    $('item').trigger(e);
});

There is some interesting discussion of the keypress events here: jQuery Event Keypress: Which key was pressed?, specifically regarding cross-browser compatability with the .which property.

This answer does not fully deal with the OP, but there are have been several times I have had a similar problem and searched for the answer.

If you can recreate the formula or the data if needed (and from your description it looks as if you can), then when you are ready to run the portion that requires the blank cells to be actually empty, then you can select the region and run the following vba macro.

Sub clearBlanks()
    Dim r As Range
    For Each r In Selection.Cells
        If Len(r.Text) = 0 Then
            r.Clear
        End If
    Next r
End Sub

this will wipe out off of the contents of any cell which is currently showing "" or has only a formula

All these answers are nice however when thinking about it....
Sometimes the most simple approach without sophistication will do the trick quicker and with no special functions.

We first set the arrays:

$arr1 = Array(
"cod" => ddd,
"denum" => ffffffffffffffff,
"descr" => ggggggg,
"cant" => 3
);
$arr2 = Array
(
"cod" => fff,
"denum" => dfgdfgdfgdfgdfg,
"descr" => dfgdfgdfgdfgdfg,
"cant" => 33
);

Then we add them to the new array :

$newArr[] = $arr1;
$newArr[] = $arr2;

Now lets see our new array with all the keys:

print_r($newArr);

There's no need for sql or special functions to build a new multi-dimensional array.... don't use a tank to get to where you can walk.

Set environment variables

This is the part that I always forget. Because you’re installing Ant by hand, you also need to deal with setting environment variables by hand.

For Windows XP: To set environment variables on Windows XP, right click on My Computer and select Properties. Then go to the Advanced tab and click the Environment Variables button at the bottom.

For Windows 7: To set environment variables on Windows 7, right click on Computer and select Properties. Click on Advanced System Settings and click the Environment Variables button at the bottom.

The dialog for both Windows XP and Windows 7 is the same. Make sure you’re only working on system variables and not user variables.

The only environment variable that you absolutely need is JAVA_HOME, which tells Ant the location of your JRE. If you’ve installed the JDK, this is likely c:\Program Files\Java\jdk1.x.x\jre on Windows XP and c:\Program Files(x86)\Java\jdk1.x.x\jre on Windows 7. You’ll note that both have spaces in their paths, which causes a problem. You need to use the mangled name[3] instead of the complete name. So for Windows XP, use C:\Progra~1\Java\jdk1.x.x\jre and for Windows 7, use C:\Progra~2\Java\jdk1.6.0_26\jre if it’s installed in the Program Files(x86) folder (otherwise use the same as Windows XP).

That alone is enough to get Ant to work, but for convenience, it’s a good idea to add the Ant binary path to the PATH variable. This variable is a semicolon-delimited list of directories to search for executables. To be able to run ant in any directory, Windows needs to know both the location for the ant binary and for the java binary. You’ll need to add both of these to the end of the PATH variable. For Windows XP, you’ll likely add something like this:

;c:\java\ant\bin;C:\Progra~1\Java\jdk1.x.x\jre\bin

For Windows 7, it will look something like this:

;c:\java\ant\bin;C:\Progra~2\Java\jdk1.x.x\jre\bin

Done

Once you’ve done that and applied the changes, you’ll need to open a new command prompt to see if the variables are set properly. You should be able to simply run ant and see something like this:

Buildfile: build.xml does not exist!
Build failed

Some more ways to iterate:

scala>  xs.foreach (println) 
first
second
third

foreach, and similar, map, which would return something (the results of the function, which is, for println, Unit, so a List of Units)

scala> val lens = for (x <- xs) yield (x.length) 
lens: Array[Int] = Array(5, 6, 5)

work with the elements, not the index

scala> ("" /: xs) (_ + _) 
res21: java.lang.String = firstsecondthird

folding

for(int i=0, j=0; i+j<100; i+=j*2, j+=i+2) {...}

can be done with recursion:

def ijIter (i: Int = 0, j: Int = 0, carry: Int = 0) : Int =
  if (i + j >= 100) carry else 
    ijIter (i+2*j, j+i+2, carry / 3 + 2 * i - 4 * j + 10) 

The carry-part is just some example, to do something with i and j. It needn't be an Int.

for simpler stuff, closer to usual for-loops:

scala> (1 until 4)
res43: scala.collection.immutable.Range with scala.collection.immutable.Range.ByOne = Range(1, 2, 3)

scala> (0 to 8 by 2)   
res44: scala.collection.immutable.Range = Range(0, 2, 4, 6, 8)

scala> (26 to 13 by -3)
res45: scala.collection.immutable.Range = Range(26, 23, 20, 17, 14)

or without order:

List (1, 3, 2, 5, 9, 7).foreach (print) 

The fastest way it is to use the Oracle collect function.

You can also do this:

select *
  2    from (
  3  select deptno,
  4         case when row_number() over (partition by deptno order by ename)=1
  5             then stragg(ename) over
  6                  (partition by deptno
  7                       order by ename
  8                         rows between unbounded preceding
  9                                  and unbounded following)
 10         end enames
 11    from emp
 12         )
 13   where enames is not null

Visit the site ask tom and search on 'stragg' or 'string concatenation' . Lots of examples. There is also a not-documented oracle function to achieve your needs.

Remove the dot and import absolute_import in the beginning of your file

from __future__ import absolute_import

from p_02_paying_debt_off_in_a_year import compute_balance_after

Janky at best

<a href="file://///server/folders/x/x/filename.ext">right click </a></td>

and then right click, select "copy location" option, and then paste into url.

As per the DOM structure you can use below code:

var x = document.getElementById('mySelect');
     var txt = "";
     var val = "";
     for (var i = 0; i < x.length; i++) {
         txt +=x[i].text + ",";
         val +=x[i].value + ",";
      }

BehaviorSubject

The BehaviorSubject builds on top of the same functionality as our ReplaySubject, subject like, hot, and replays previous value.

The BehaviorSubject adds one more piece of functionality in that you can give the BehaviorSubject an initial value. Let’s go ahead and take a look at that code

import { ReplaySubject } from 'rxjs';

const behaviorSubject = new BehaviorSubject(
  'hello initial value from BehaviorSubject'
);

behaviorSubject.subscribe(v => console.log(v));

behaviorSubject.next('hello again from BehaviorSubject');

Observables

To get started we are going to look at the minimal API to create a regular Observable. There are a couple of ways to create an Observable. The way we will create our Observable is by instantiating the class. Other operators can simplify this, but we will want to compare the instantiation step to our different Observable types

import { Observable } from 'rxjs';

const observable = new Observable(observer => {
  setTimeout(() => observer.next('hello from Observable!'), 1000);
});

observable.subscribe(v => console.log(v));

That only means that an undefined column or parameter name was detected. The errror that DB2 gives should point what that may be:

DB2 SQL Error: SQLCODE=-206, SQLSTATE=42703, SQLERRMC=[THE_UNDEFINED_COLUMN_OR_PARAMETER_NAME], DRIVER=4.8.87

Double check your table definition. Maybe you just missed adding something.

I also tried google-ing this problem and saw this:

A generic answer on how to handle click events with KnockoutJS...

Not a straight up answer to the question as asked, but probably an answer to the question most Googlers landing here have: use the click binding from KnockoutJS instead of onclick. Like this:

function Item(parent, txt) {_x000D_
  var self = this;_x000D_
  _x000D_
  self.doStuff = function(data, event) {_x000D_
    console.log(data, event);_x000D_
    parent.log(parent.log() + "\n  data = " + ko.toJSON(data));_x000D_
  };_x000D_
  _x000D_
  self.doOtherStuff = function(customParam, data, event) {_x000D_

**A note about the actual question...*

The actual question has one interesting bit:

// Uh oh! Modifying the DOM....
place.innerHTML = "somthing"

Don't do that! Don't modify the DOM like that when using an MVVM framework like KnockoutJS, especially not the piece of the DOM that is your own parent. If you would do this the button would disappear (if you replace your parent's innerHTML you yourself will be gone forever ever!).

Instead, modify the View Model in your handler instead, and have the View respond. For example:

function RootVm() {_x000D_
  var self = this;_x000D_
  self.buttonWasClickedOnce = ko.observable(false);_x000D_
  self.toggle = function(data, event) {_x000D_
    self.buttonWasClickedOnce(!self.buttonWasClickedOnce());_x000D_
  };_x000D_

var json = jQuery.parseJSON(s); //If you have jQuery.

Since the comment looks cluttered, please use the parse function after enclosing those square brackets inside the quotes.

var s=['{"Select":"11","PhotoCount":"12"}','{"Select":"21","PhotoCount":"22"}'];

Change the above code to

var s='[{"Select":"11","PhotoCount":"12"},{"Select":"21","PhotoCount":"22"}]';

Eg:

$(document).ready(function() {
    var s= '[{"Select":"11","PhotoCount":"12"},{"Select":"21","PhotoCount":"22"}]';

    s = jQuery.parseJSON(s);

    alert( s[0]["Select"] );
});

And then use the parse function. It'll surely work.

EDIT :Extremely sorry that I gave the wrong function name. it's jQuery.parseJSON

Jquery

The json api

Edit (30 April 2020):

Editing since I got an upvote for this answer. There's a browser native function available instead of JQuery (for nonJQuery users), JSON.parse("<json string here>")

Downloaded Eclipse Luna and installed WTP using http://download.eclipse.org/webtools/repository/luna

Downloaded Tomcat 8 and configured new server in Eclipse. I am able to setup tomcat 8 now in Eclipse luna

You can try:

{{ 1 * num_str + 1 }}

I had this problem. I searched the internet, took all advices, changes configurations, but the problem is still there. Finally with the help of the server administrator, he found that the problem lies in MySQL database column definition. one of the columns in the a table was assigned to 'Longtext' which leads to allocate 4,294,967,295 bites of memory. It seems working OK if you don't use MySqli prepare statement, but once you use prepare statement, it tries to allocate that amount of memory. I changed the column type to Mediumtext which needs 16,777,215 bites of memory space. The problem is gone. Hope this help.

This works for me on OSX.
