This code will let you have a variable number of rows (with a variable number of DIVs on each row) and it will make all of the DIVs on each row match the height of its tallest neighbour:

If we assumed all the DIVs, that are floating, are inside a container with the id "divContainer", then you could use the following:

$(document).ready(function() {

var currentTallest = 0;
var currentRowStart = 0;
var rowDivs = new Array();

$('div#divContainer div').each(function(index) {

    if(currentRowStart != $(this).position().top) {

        // we just came to a new row.  Set all the heights on the completed row
        for(currentDiv = 0 ; currentDiv < rowDivs.length ; currentDiv++) rowDivs[currentDiv].height(currentTallest);

        // set the variables for the new row
        rowDivs.length = 0; // empty the array
        currentRowStart = $(this).position().top;
        currentTallest = $(this).height();
        rowDivs.push($(this));

    } else {

        // another div on the current row.  Add it to the list and check if it's taller
        rowDivs.push($(this));
        currentTallest = (currentTallest < $(this).height()) ? ($(this).height()) : (currentTallest);

    }
    // do the last row
    for(currentDiv = 0 ; currentDiv < rowDivs.length ; currentDiv++) rowDivs[currentDiv].height(currentTallest);

});
});

If you have or are already using lodash, use last instead:

_.last(str);

Not only is it more concise and obvious than the vanilla JS, it also safer since it avoids Uncaught TypeError: Cannot read property X of undefined when the input is null or undefined so you don't need to check this beforehand:

// Will throws Uncaught TypeError if str is null or undefined
str.slice(-1); // 
str.charAt(str.length -1);

// Returns undefined when str is null or undefined
_.last(str);

You can use the assertThat method and the Matchers that comes with JUnit.

Take a look at this link that describes a little bit about the JUnit Matchers.

Example:

public class BaseClass {
}

public class SubClass extends BaseClass {
}

Test:

import org.junit.Test;

import static org.hamcrest.CoreMatchers.instanceOf;
import static org.junit.Assert.assertThat;

/**
 * @author maba, 2012-09-13
 */
public class InstanceOfTest {

    @Test
    public void testInstanceOf() {
        SubClass subClass = new SubClass();
        assertThat(subClass, instanceOf(BaseClass.class));
    }
}

Explain only shows how the optimizer thinks the query will execute.

To show the real plan, you will need to run the sql once. Then use the same session run the following:

@yoursql 
select * from table(dbms_xplan.display_cursor()) 

This way can show the real plan used during execution. There are several other ways in showing plan using dbms_xplan. You can Google with term "dbms_xplan".

Move all of your state and your handleClick function from Header to your MainWrapper component.

Then pass values as props to all components that need to share this functionality.

class MainWrapper extends React.Component {
    constructor() {
        super();
        this.state = {
            sidbarPushCollapsed: false,
            profileCollapsed: false
        };
        this.handleClick = this.handleClick.bind(this);
    }
    handleClick() {
        this.setState({
            sidbarPushCollapsed: !this.state.sidbarPushCollapsed,
            profileCollapsed: !this.state.profileCollapsed

        });
    }
    render() {
        return (
           //...
           <Header 
               handleClick={this.handleClick} 
               sidbarPushCollapsed={this.state.sidbarPushCollapsed}
               profileCollapsed={this.state.profileCollapsed} />
        );

Then in your Header's render() method, you'd use this.props:

<button type="button" id="sidbarPush" onClick={this.props.handleClick} profile={this.props.profileCollapsed}>

You can just do:

print(command_stdout.decode('utf-8'))

Perhaps with dataframes one of the most easy and practical solution is:

data = dplyr::mutate(data, rownum=row_number())

Use subscripting to access the value for a dictionary key. This will return an Optional:

let apple: String? = companies["AAPL"]

or

if let apple = companies["AAPL"] {
    // ...
}

You can also enumerate over all of the keys and values:

var companies = ["AAPL" : "Apple Inc", "GOOG" : "Google Inc", "AMZN" : "Amazon.com, Inc", "FB" : "Facebook Inc"]

for (key, value) in companies {
    print("\(key) -> \(value)")
}

Or enumerate over all of the values:

for value in Array(companies.values) {
    print("\(value)")
}

You can also try this:

scp -r /cygdrive/c/desktop/myfolder/deployments/ user@host:/path/to/whereyouwant/thefile

You don't mention if this is an anonymous PL/SQL block or a declarative one ie. Package, Procedure or Function. However, in PL/SQL a COMMIT must be explicitly made to save your transaction(s) to the database. The COMMIT actually saves all unsaved transactions to the database from your current user's session.

If an error occurs the transaction implicitly does a ROLLBACK.

This is the default behaviour for PL/SQL.

CSS

For basic styling its OK, and selectors are pretty cool, but there's something a little bit sadistic about the box model, floats and clearing.

Hacking the language to make it do fundamental things, such as move one box below another, is all in a days work.

Here we are living in the future and just getting basic design elements to work, like rounded corners or drop shadows, is an exercise in futility.

The concept of 'reusability' pretty much ends with Ctrl-C Ctrl-V. Even a seasoned CSS writer will rarely touch someone else's stylesheet - meaning that basic layouts are routinely rewritten again and again all around the world.

Of course it shouldn't take all the flack - any hope it had of offering something truly useful to the world was cruelly dashed upon the rocks by the de facto 'platform' for the language - Internet Explorer.

I had this same issue and this fiddle is the shizzle :) It uses a directive to properly style the file field and you can even make it an image or whatever.

You can try the following. It's working...

#include <iostream>
#include <fstream>
#include <string>
#include <sstream>
using namespace std;

template <class T>
string to_string(T t, ios_base & (*f)(ios_base&))

  oss << f << t;
  return oss.str();
}

int main ()
{
  cout<<to_string<long>(123456, hex)<<endl;
  system("PAUSE");
  return 0;
}

What I did was: created a new provisioning profile and used it. When setup the provisioning profile in the build setting tab, there were the wrong provisioning profile numbers (like "983ff..." as the error message mentioned, that's it!). Corrected to the new provisioning profile, then Xcode 7.2 refreshed itself, and build successfully.

This should work:

# To export to file (data only)
mysqldump -u [user] -p[pass] --no-create-info mydb > mydb.sql

# To export to file (structure only)
mysqldump -u [user] -p[pass] --no-data mydb > mydb.sql

# To import to database
mysql -u [user] -p[pass] mydb < mydb.sql

NOTE: there's no space between -p & [pass]

I found good solution for any format of request body. I tested for application/x-www-form-urlencoded and application/json both worked very well. Problem of ContentCachingRequestWrapper that is designed only for x-www-form-urlencoded request body, but not work with e.g. json. I found solution for json link. It had trouble that it didn't support x-www-form-urlencoded. I joined both in my code:

import org.apache.commons.io.IOUtils;
import org.springframework.web.util.ContentCachingRequestWrapper;

import javax.servlet.ReadListener;
import javax.servlet.ServletInputStream;
import javax.servlet.http.HttpServletRequest;
import java.io.BufferedReader;
import java.io.ByteArrayInputStream;
import java.io.IOException;
import java.io.InputStreamReader;

public class MyContentCachingRequestWrapper extends ContentCachingRequestWrapper {

    private byte[] body;

    public MyContentCachingRequestWrapper(HttpServletRequest request) throws IOException {
        super(request);
        super.getParameterMap(); // init cache in ContentCachingRequestWrapper
        body = super.getContentAsByteArray(); // first option for application/x-www-form-urlencoded
        if (body.length == 0) {
          try {
            body = IOUtils.toByteArray(super.getInputStream()); // second option for other body formats
          } catch (IOException ex) {
            body = new byte[0];
          }
        }
    }

    public byte[] getBody() {
        return body;
    }

    @Override
    public ServletInputStream getInputStream() {
        return new RequestCachingInputStream(body);
    }

    @Override
    public BufferedReader getReader() throws IOException {
        return new BufferedReader(new InputStreamReader(getInputStream(), getCharacterEncoding()));
    }

    private static class RequestCachingInputStream extends ServletInputStream {

        private final ByteArrayInputStream inputStream;

        public RequestCachingInputStream(byte[] bytes) {
            inputStream = new ByteArrayInputStream(bytes);
        }

        @Override
        public int read() throws IOException {
            return inputStream.read();
        }

        @Override
        public boolean isFinished() {
            return inputStream.available() == 0;
        }

        @Override
        public boolean isReady() {
            return true;
        }

        @Override
        public void setReadListener(ReadListener readlistener) {
        }

    }

}

If you are using SQL Server try Linked Server

I use them sparingly, but they can be pretty convenient:

def log(msg):
   log.logfile.write(msg)

Now I can use log throughout my module, and redirect output simply by setting log.logfile. There are lots and lots of other ways to accomplish that, but this one's lightweight and dirt simple. And while it smelled funny the first time I did it, I've come to believe that it smells better than having a global logfile variable.

You can do

<CheckBox
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:gravity="right|center"//or "center_vertical" for center text
android:layoutDirection="rtl"
android:text="hello" />

Following line is enough

android:layoutDirection="rtl"

In my case, one of my testing targets was working but the other one was not. It was giving the above error with a missing library or whatever. I compared the settings for both of the testing targets and found that one was missing the configuration for "Test Host", so I copied that from the working test target and it fixed my broken test target!

For those guys who are tying to find the DatePickerDoneClick function... here is the simple code to dismiss the Action Sheet. Obviously aac should be an ivar (the one which goes in your implmentation .h file)

- (void)DatePickerDoneClick:(id)sender{
    [aac dismissWithClickedButtonIndex:0 animated:YES];
}

with open("Stud.txt", "rt") as fin:
    with open("out.txt", "wt") as fout:
        for line in fin:
            fout.write(line.replace('A', 'Orange'))

You might have old invalid username/password cached in your browser. Try clearing them and check again.

If you are using IE and somesite.com is in your Intranet security zone, IE may be sending your windows credentials automatically.

puts call the to_s of each argument and adds a new line to each string, if it does not end with new line. print just output each argument by calling their to_s.

for example: puts "one two": one two

{new line}

puts "one two\n": one two

{new line} #puts will not add a new line to the result, since the string ends with a new line

print "one two": one two

print "one two\n": one two

{new line}

And there is another way to output: p

For each object, directly writes obj.inspect followed by a newline to the program’s standard output.

It is helpful to output debugging message. p "aa\n\t": aa\n\t

Really! after spending 4 hours and insane debugging I found this very strange code at com.fasterxml.jackson.databind.deser.DeserializerCache

if (deser == null) {
    try {
        deser = _createAndCacheValueDeserializer(ctxt, factory, type);
    } catch (Exception e) {
        return false;
    }
}

Ya, the problem was double setter.

If you need to count a more complex query, with groupBy, having etc... You can borrow from Doctrine\ORM\Tools\Pagination\Paginator:

$paginator = new \Doctrine\ORM\Tools\Pagination\Paginator($query);
$totalRows = count($paginator);

The animate(..) function' signature is:

.animate( properties, options );

And it says the following about the parameter properties:

properties A map of CSS properties that the animation will move toward.

text is not a CSS property, this is why the function isn't working as you expected.

Do you want to fade the text out? Do you want to move it? I might be able to provide an alternative.

Have a look at the following fiddle.

This is the best way to do it as used on the BBC website and the Guardian:

I found the technique here: http://codepen.io/IschaGast/pen/Qjxpxo

heres the html

<div class="highlight block-link">
      <h2>I am an example header</h2>
      <p><a href="pageone" class="block-link__overlay-link">This entire box</a> links somewhere, thanks to faux block links. I am some example text with a <a href="pagetwo">custom link</a> that sits within the block</p>

</div>

heres the CSS

/**
 * Block Link
 *
 * A Faux block-level link. Used for when you need a block-level link with
 * clickable areas within it as directly nesting a tags breaks things.
 */


.block-link {
    position: relative;
}

.block-link a {
  position: relative;
  z-index: 1;
}

.block-link .block-link__overlay-link {
    position: static;
    &:before {
      bottom: 0;
      content: "";
      left: 0;
      overflow: hidden;
      position: absolute;
      right: 0;
      top: 0;
      white-space: nowrap;
      z-index: 0;
    }
    &:hover,
    &:focus {
      &:before {
        background: rgba(255,255,0, .2);
      }
    }
}

just use UPDATE query without condition like this

 UPDATE tablename SET online_status=0;

import java.io.Serializable;
import java.util.ArrayList;
import java.util.List;
import javax.persistence.CascadeType;
import javax.persistence.Column;
import javax.persistence.Entity;
import javax.persistence.GeneratedValue;
import javax.persistence.GenerationType;
import javax.persistence.Id;
import javax.persistence.OneToMany;
import javax.persistence.Table;

@Entity
@Table(name="empTable")
public class Employee implements Serializable{
private static final long serialVersionUID = 1L;
private int id;
private String empName;

List<Address> addList=new ArrayList<Address>();


@Id
@GeneratedValue(strategy=GenerationType.IDENTITY)
@Column(name="emp_id")
public int getId() {
    return id;
}
public void setId(int id) {
    this.id = id;
}
public String getEmpName() {
    return empName;
}
public void setEmpName(String empName) {
    this.empName = empName;
}

@OneToMany(mappedBy="employee",cascade=CascadeType.ALL)
public List<Address> getAddList() {
    return addList;
}

public void setAddList(List<Address> addList) {
    this.addList = addList;
}
}

We have two entities Employee and Address with One to Many relationship.

import java.io.Serializable;
import javax.persistence.Entity;
import javax.persistence.GeneratedValue;
import javax.persistence.GenerationType;
import javax.persistence.Id;
import javax.persistence.JoinColumn;
import javax.persistence.ManyToOne;
import javax.persistence.Table;

@Entity
@Table(name="address")
public class Address implements Serializable{

private static final long serialVersionUID = 1L;

private int address_id;
private String address;
Employee employee;

@Id
@GeneratedValue(strategy=GenerationType.IDENTITY)
public int getAddress_id() {
    return address_id;
}
public void setAddress_id(int address_id) {
    this.address_id = address_id;
}
public String getAddress() {
    return address;
}
public void setAddress(String address) {
    this.address = address;
}

@ManyToOne
@JoinColumn(name="emp_id")
public Employee getEmployee() {
    return employee;
}
public void setEmployee(Employee employee) {
    this.employee = employee;
}
}

By this way we can implement inner join between two tables

import java.util.List;
import org.hibernate.Query;
import org.hibernate.Session;

public class Main {

public static void main(String[] args) {
    saveEmployee();

    retrieveEmployee();

}

private static void saveEmployee() {
    Employee employee=new Employee();
    Employee employee1=new Employee();
    Employee employee2=new Employee();
    Employee employee3=new Employee();

    Address address=new Address();
    Address address1=new Address();
    Address address2=new Address();
    Address address3=new Address();

    address.setAddress("1485,Sector 42 b");
    address1.setAddress("1485,Sector 42 c");
    address2.setAddress("1485,Sector 42 d");
    address3.setAddress("1485,Sector 42 a");

    employee.setEmpName("Varun");
    employee1.setEmpName("Krishan");
    employee2.setEmpName("Aasif");
    employee3.setEmpName("Dut");

    address.setEmployee(employee);
    address1.setEmployee(employee1);
    address2.setEmployee(employee2);
    address3.setEmployee(employee3);

    employee.getAddList().add(address);
    employee1.getAddList().add(address1);
    employee2.getAddList().add(address2);
    employee3.getAddList().add(address3);

    Session session=HibernateUtil.getSessionFactory().openSession();

    session.beginTransaction();

    session.save(employee);
    session.save(employee1);
    session.save(employee2);
    session.save(employee3);
    session.getTransaction().commit();
    session.close();
}

private static void retrieveEmployee() {
    try{

    String sqlQuery="select e from Employee e inner join e.addList";

    Session session=HibernateUtil.getSessionFactory().openSession();

    Query query=session.createQuery(sqlQuery);

    List<Employee> list=query.list();

     list.stream().forEach((p)->{System.out.println(p.getEmpName());});     
    session.close();
    }catch(Exception e){
        e.printStackTrace();
    }
}
}

I have used Java 8 for loop for priting the names. Make sure you have jdk 1.8 with tomcat 8. Also add some more records for better understanding.

 public class HibernateUtil {
 private static SessionFactory sessionFactory ;
 static {
    Configuration configuration = new Configuration();

    configuration.addAnnotatedClass(Employee.class);
    configuration.addAnnotatedClass(Address.class);
                  configuration.setProperty("connection.driver_class","com.mysql.jdbc.Driver");
    configuration.setProperty("hibernate.connection.url", "jdbc:mysql://localhost:3306/hibernate");                                
    configuration.setProperty("hibernate.connection.username", "root");     
    configuration.setProperty("hibernate.connection.password", "root");
    configuration.setProperty("dialect", "org.hibernate.dialect.MySQLDialect");
    configuration.setProperty("hibernate.hbm2ddl.auto", "update");
    configuration.setProperty("hibernate.show_sql", "true");
    configuration.setProperty(" hibernate.connection.pool_size", "10");


   // configuration
    StandardServiceRegistryBuilder builder = new StandardServiceRegistryBuilder().applySettings(configuration.getProperties());
    sessionFactory = configuration.buildSessionFactory(builder.build());
 }
public static SessionFactory getSessionFactory() {
    return sessionFactory;
}
} 

Try:

System.exit(0);

Crude, but effective.

After using correct syntax in all of your code, please see if you have mentioned your component in the declarations of your angular module. Something like below:

@NgModule({ declarations: [ AppComponent, YourComponent ],

filenames must sort correctly to combine correctly!

file1.bin file2.bin ... file10.bin wont work properly

file01.bin file02.bin ... file10.bin will work properly

c:>for %i in (file*.bin) do type %i >> onebinary.bin

Works for ascii or binary files.

On Windows platform, it is also possible to capture localhost traffic using Wireshark. What you need to do is to install the Microsoft loopback adapter, and then sniff on it.

When you use autofilter to filter results, Excel doesn't even bother to hide them: it just sets the height of the row to zero (up to 2003 at least, not sure on 2007).

So the following custom function should give you a starter to do what you want (tested with integers, haven't played with anything else):

Function SumVis(r As Range)
    Dim cell As Excel.Range
    Dim total As Variant

    For Each cell In r.Cells
        If cell.Height <> 0 Then
            total = total + cell.Value
        End If
    Next

    SumVis = total
End Function

Edit:

You'll need to create a module in the workbook to put the function in, then you can just call it on your sheet like any other function (=SumVis(A1:A14)). If you need help setting up the module, let me know.

use

 $(document).height()

  overflow=auto 

for scrolling

RexExp instances have a lastIndex property already (if they are global) and so what I'm doing is copying the regular expression, modifying it slightly to suit our purposes, exec-ing it on the string and looking at the lastIndex. This will inevitably be faster than looping on the string. (You have enough examples of how to put this onto the string prototype, right?)

function reIndexOf(reIn, str, startIndex) {
    var re = new RegExp(reIn.source, 'g' + (reIn.ignoreCase ? 'i' : '') + (reIn.multiLine ? 'm' : ''));
    re.lastIndex = startIndex || 0;
    var res = re.exec(str);
    if(!res) return -1;
    return re.lastIndex - res[0].length;
};

function reLastIndexOf(reIn, str, startIndex) {
    var src = /\$$/.test(reIn.source) && !/\\\$$/.test(reIn.source) ? reIn.source : reIn.source + '(?![\\S\\s]*' + reIn.source + ')';
    var re = new RegExp(src, 'g' + (reIn.ignoreCase ? 'i' : '') + (reIn.multiLine ? 'm' : ''));
    re.lastIndex = startIndex || 0;
    var res = re.exec(str);
    if(!res) return -1;
    return re.lastIndex - res[0].length;
};

reIndexOf(/[abc]/, "tommy can eat");  // Returns 6
reIndexOf(/[abc]/, "tommy can eat", 8);  // Returns 11
reLastIndexOf(/[abc]/, "tommy can eat"); // Returns 11

You could also prototype the functions onto the RegExp object:

RegExp.prototype.indexOf = function(str, startIndex) {
    var re = new RegExp(this.source, 'g' + (this.ignoreCase ? 'i' : '') + (this.multiLine ? 'm' : ''));
    re.lastIndex = startIndex || 0;
    var res = re.exec(str);
    if(!res) return -1;
    return re.lastIndex - res[0].length;
};

RegExp.prototype.lastIndexOf = function(str, startIndex) {
    var src = /\$$/.test(this.source) && !/\\\$$/.test(this.source) ? this.source : this.source + '(?![\\S\\s]*' + this.source + ')';
    var re = new RegExp(src, 'g' + (this.ignoreCase ? 'i' : '') + (this.multiLine ? 'm' : ''));
    re.lastIndex = startIndex || 0;
    var res = re.exec(str);
    if(!res) return -1;
    return re.lastIndex - res[0].length;
};


/[abc]/.indexOf("tommy can eat");  // Returns 6
/[abc]/.indexOf("tommy can eat", 8);  // Returns 11
/[abc]/.lastIndexOf("tommy can eat"); // Returns 11

A quick explanation of how I am modifying the RegExp: For indexOf I just have to ensure that the global flag is set. For lastIndexOf of I am using a negative look-ahead to find the last occurrence unless the RegExp was already matching at the end of the string.

This question has lots of good answers even for .Net Core. I was using both Frameworks the provided code samples work fine. So I won't repeat it. In my case the important thing was how to use File upload actions with Swagger like this:

Here is my recap:

ASP .Net WebAPI 2

• To upload file use: MultipartFormDataStreamProvider see answers here
• How to use it with Swagger

.NET Core

• To upload file use: IFormFile see answers here or MS documentation
• How to use it with Swagger

var dt = new Date(); // current date of week
var currentWeekDay = dt.getDay();
var lessDays = currentWeekDay == 0 ? 6 : currentWeekDay - 1;
var wkStart = new Date(new Date(dt).setDate(dt.getDate() - lessDays));
var wkEnd = new Date(new Date(wkStart).setDate(wkStart.getDate() + 6));

This will work well.

To change the button background we can follow 2 methods

1. In the button OnClick, just add this code:

    public void onClick(View v) {
        if(v == buttonName) {
           buttonName.setBackgroundDrawable
            (getResources().getDrawable(R.drawable.imageName_selected));
         }
   
          }
   

   2.Create button_background.xml in the drawable folder.(using xml)

   res -> drawable -> button_background.xml

      <?xml version="1.0" encoding="UTF-8"?>
       <selector xmlns:android="http://schemas.android.com/apk/res/android">
   
            <item android:state_selected="true"
                  android:drawable="@drawable/tabs_selected" /> <!-- selected-->
            <item android:state_pressed="true"
                  android:drawable="@drawable/tabs_selected" /> <!-- pressed-->
            <item  android:drawable="@drawable/tabs_selected"/>
       </selector>
   

   Now set the above file in button's background file.

        <Button
              android:layout_width="fill_parent" 
              android:layout_height="wrap_content"
              android:background="@drawable/button_background"/>
   
                             (or)
   
            Button tiny = (Button)findViewById(R.id.tiny);
                  tiny.setBackgroundResource(R.drawable.abc);
   

   2nd method is better for setting the background fd button

I hide the warnings in the pink boxes by running the following code in a cell:

from IPython.display import HTML
HTML('''<script>

 $('div.output_stderr').hide();
 } else {
 $('div.output_stderr').show();
 }
 code_show_err = !code_show_err
} 
$( document ).ready(code_toggle_err);
</script>
To toggle on/off output_stderr, click <a href="javascript:code_toggle_err()">here</a>.''')

Yes, you can use any of these popular tools:

As apparantly no one mentioned it: you can also use the Numpy Docstring Standard. It is widely used in the scientific community.

• The specification of the format from numpy together with an example
• You have a sphinx extension to render it: numpydoc
• And an example of how beautiful a rendered docstring can look like: http://docs.scipy.org/doc/numpy/reference/generated/numpy.mean.html

The Napolean sphinx extension to parse Google-style docstrings (recommended in the answer of @Nathan) also supports Numpy-style docstring, and makes a short comparison of both.

And last a basic example to give an idea how it looks like:

def func(arg1, arg2):
    """Summary line.

    Extended description of function.

    Parameters
    ----------
    arg1 : int
        Description of arg1
    arg2 : str

    Returns
    -------
    bool
        Description of return value

    See Also
    --------
    otherfunc : some related other function

    Examples

    These are written in doctest format, and should illustrate how to

Below is an action method that returns a json string (cameCase) by serializing an array of objects.

public string GetSerializedCourseVms()
    {
        var courses = new[]
        {
            new CourseVm{Number = "CREA101", Name = "Care of Magical Creatures", Instructor ="Rubeus Hagrid"},
            new CourseVm{Number = "DARK502", Name = "Defence against dark arts", Instructor ="Severus Snape"},
            new CourseVm{Number = "TRAN201", Name = "Transfiguration", Instructor ="Minerva McGonal"}
        };
        var camelCaseFormatter = new JsonSerializerSettings();
        camelCaseFormatter.ContractResolver = new CamelCasePropertyNamesContractResolver();
        return JsonConvert.SerializeObject(courses, camelCaseFormatter);
    }

Note the JsonSerializerSettings instance passed as the second parameter. That's what makes the camelCase happen.

Note: This answer was intended for a very specific question. For most programmers coming here from a search engine, this is not the answer you are looking for. Typically you would structure your files into packages (see other answers) instead of modifying the search path.

By default, you can't. When importing a file, Python only searches the directory that the entry-point script is running from and sys.path which includes locations such as the package installation directory (it's actually a little more complex than this, but this covers most cases).

However, you can add to the Python path at runtime:

# some_file.py
import sys
# insert at 1, 0 is the script path (or '' in REPL)
sys.path.insert(1, '/path/to/application/app/folder')

import file

You cannot put spaces around the = sign when you do:

export foo=bar

Remove the spaces you have and you should be good to go.

If you type:

export foo = bar

the shell will interpret that as a request to export three names: foo, = and bar. = isn't a valid variable name, so the command fails. The variable name, equals sign and it's value must not be separated by spaces for them to be processed as a simultaneous assignment and export.

If you want one row for each filename, reflecting a specific states and listing the most recent date then this is your friend:

select filename ,
       status   ,
       max_date = max( dates )
from some_table t
group by filename , status
having status = '<your-desired-status-here>'

Easy!

You're asking the wrong question. The codebehind (controller) has nothing to do with what the frontend does. In fact, that's the strength of MVC -- you separate the code/concept from the view.

If you want an action to open in a new window, then links to that action need to tell the browser to open a new window when clicked.

A pseudo example: <a href="NewWindow" target="_new">Click Me</a>

And that's all there is to it. Set the target of links to that action.

First, check that your origin is set by running

git remote -v

This should show you all of the push / fetch remotes for the project.

If this returns with no output, skip to last code block.

Verify remote name / address

If this returns showing that you have remotes set, check that the name of the remote matches the remote you are using in your commands.

$git remote -v
myOrigin ssh://[email protected]:1234/myRepo.git (fetch)
myOrigin ssh://[email protected]:1234/myRepo.git (push)

# this will fail because `origin` is not set
$git push origin master

# you need to use
$git push myOrigin master

If you want to rename the remote or change the remote's URL, you'll want to first remove the old remote, and then add the correct one.

Remove the old remote

$git remote remove myOrigin

Add missing remote

You can then add in the proper remote using

$git remote add origin ssh://[email protected]:1234/myRepo.git

# this will now work as expected
$git push origin master

i got this to work by copy pasting the signed app in the same dir as zipalign. It seems that aapt.exe could not find the source file even when given the path. i.e. this did not work zipalign -f -v 4 C:...\CordovaApp-release-unsigned.apk C:...\destination.apk it reached aapt.exeCordovaApp-release-unsigned.apk , froze and upon hitting return 'aapt.exeCordovaApp-release-unsigned.apk' is not recognized as an internal or external command, operable program or batch file. And this did zipalign -f -v 4 CordovaApp-release-unsigned.apk myappname.apk

You can consider to replace default WordPress jQuery script with Google Library by adding something like the following into theme functions.php file:

function modify_jquery() {
    if (!is_admin()) {
        wp_deregister_script('jquery');
        wp_register_script('jquery', 'http://ajax.googleapis.com/ajax/libs/jquery/1.10.2/jquery.min.js', false, '1.10.2');
        wp_enqueue_script('jquery');
    }
}
add_action('init', 'modify_jquery');

If your form tag is like

<form action="" method="post" id="BookPackageForm">

Then fetch the form element by using forms object.

var formEl = document.forms.BookPackageForm;

Get the data from the form by using FormData objects.

var formData = new FormData(formEl);

Get the value of the fields by the form data object.

var name = formData.get('name');

RecyclerView was created as a ListView improvement, so yes, you can create an attached list with ListView control, but using RecyclerView is easier as it:

1. Reuses cells while scrolling up/down - this is possible with implementing View Holder in the ListView adapter, but it was an optional thing, while in the RecycleView it's the default way of writing adapter.

2. Decouples list from its container - so you can put list items easily at run time in the different containers (linearLayout, gridLayout) with setting LayoutManager.

Example:

mRecyclerView = (RecyclerView) findViewById(R.id.my_recycler_view);
mRecyclerView.setLayoutManager(new LinearLayoutManager(this));
//or
mRecyclerView.setLayoutManager(new GridLayoutManager(this, 2));

3. Animates common list actions - Animations are decoupled and delegated to ItemAnimator.

There is more about RecyclerView, but I think these points are the main ones.

So, to conclude, RecyclerView is a more flexible control for handling "list data" that follows patterns of delegation of concerns and leaves for itself only one task - recycling items.

I know this is a super old post, but I figured this may still be helpful.

If you're comfortable with reading json format you could replace your var_dump with:

return json_encode($myvar);

I've been using this to help troubleshoot a service I've been building that has some deeply nested arrays. This will return every level of your array without truncating anything or requiring you to change your php.ini file.

Also, because the json_encoded data is a string it means you can write it to the error log easily

error_log(json_encode($myvar));

It probably isn't the best choice for every situation, but it's a choice!

First, remember your JPanel size height and size width, then observe: JButton coordinates is (xo, yo, x length , y length). If your window is 800x600, you just need to write:

JButton.setBounds(0, 500, 100, 100);

You just need to use a coordinate gap to represent the button, and know where the window ends and where the window begins.

This message show the alert message directly

ScriptManager.RegisterStartupScript(this,GetType(),"showalert","alert('Only alert Message');",true);

This message show alert message from JavaScript function

ScriptManager.RegisterStartupScript(this, GetType(), "displayalertmessage", "Showalert();", true);

These are two ways to display alert messages in c# code behind

How to get rid of a header(first row) and an index(first column).

To write to CSV file:

df = pandas.DataFrame(your_array)
df.to_csv('your_array.csv', header=False, index=False)

To read from CSV file:

df = pandas.read_csv('your_array.csv')
a = df.values

If you want to read a CSV file that doesn't contain a header, pass additional parameter header:

df = pandas.read_csv('your_array.csv', header=None)

Another way without JavaScript is to use <form autocomplete="off"> to prevent the browser from re-filling the form with the last values.

See also this question

Tested this only with a single <input type="text"> inside the form, but works fine in current Chrome and Firefox, unfortunately not in IE10.

For me was because I put the animation name inside square brackets.

<div [@animation]></div>

But after I removed the bracket all worked fine (In Angular 9.0.1):

<div @animation></div>

Following recursive function I have written, if it helps anyone. It will copy all the files inside sourcedirectory to destinationDirectory.

example:

rfunction("D:/MyDirectory", "D:/MyDirectoryNew", "D:/MyDirectory");

public static void rfunction(String sourcePath, String destinationPath, String currentPath) {
    File file = new File(currentPath);
    FileInputStream fi = null;
    FileOutputStream fo = null;

    if (file.isDirectory()) {
        String[] fileFolderNamesArray = file.list();
        File folderDes = new File(destinationPath);
        if (!folderDes.exists()) {
            folderDes.mkdirs();
        }

        for (String fileFolderName : fileFolderNamesArray) {
            rfunction(sourcePath, destinationPath + "/" + fileFolderName, currentPath + "/" + fileFolderName);
        }
    } else {
        try {
            File destinationFile = new File(destinationPath);

            fi = new FileInputStream(file);
            fo = new FileOutputStream(destinationPath);
            byte[] buffer = new byte[1024];
            int ind = 0;
            while ((ind = fi.read(buffer))>0) {
                fo.write(buffer, 0, ind);
            }
        } catch (FileNotFoundException e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
        } catch (IOException e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
        }
        finally {
            if (null != fi) {
                try {
                    fi.close();
                } catch (IOException e) {
                    // TODO Auto-generated catch block
                    e.printStackTrace();
                }
            }
            if (null != fo) {
                try {
                    fo.close();
                } catch (IOException e) {
                    // TODO Auto-generated catch block
                    e.printStackTrace();
                }
            }
        }
    }
}

There is only a simple way to find modulo of 2^i numbers using bitwise.

There is an ingenious way to solve Mersenne cases as per the link such as n % 3, n % 7... There are special cases for n % 5, n % 255, and composite cases such as n % 6.

For cases 2^i, ( 2, 4, 8, 16 ...)

n % 2^i = n & (2^i - 1)

More complicated ones are hard to explain. Read up only if you are very curious.

Not so hard:

#include <thread>

void Test::runMultiThread()
{
    std::thread t1(&Test::calculate, this,  0, 10);
    std::thread t2(&Test::calculate, this, 11, 20);
    t1.join();
    t2.join();
}

If the result of the computation is still needed, use a future instead:

#include <future>

void Test::runMultiThread()
{
     auto f1 = std::async(&Test::calculate, this,  0, 10);
     auto f2 = std::async(&Test::calculate, this, 11, 20);

     auto res1 = f1.get();
     auto res2 = f2.get();
}

Use Persistent Volume Claim (PVC) from Kubernetes, which is a Docker container management and scheduling tool:

Persistent Volumes

The advantages of using Kubernetes for this purpose are that:

• You can use any storage like NFS or other storage and even when the node is down, the storage need not be.
• Moreover the data in such volumes can be configured to be retained even after the container itself is destroyed - so that it can be reclaimed, if necessary, by another container.

Edit the pg_hba.conf file, e.g. with sudo emacs /etc/postgresql/9.3/main/pg_hba.conf

Change all authentication methods to trust. Change Unix Password for "postgres" user. Restart Server. Login with psql -h localhost -U postgres and use the just set Unix password. If it works you can re-set the pg_hba.conf file to the default values.

After checking catalina.sh (for windows use the .bat versions of everything mentioned below)

#   Do not set the variables in this script. Instead put them into a script
#   setenv.sh in CATALINA_BASE/bin to keep your customizations separate.

Also this

#   CATALINA_OPTS   (Optional) Java runtime options used when the "start",
#                   "run" or "debug" command is executed.
#                   Include here and not in JAVA_OPTS all options, that should
#                   only be used by Tomcat itself, not by the stop process,
#                   the version command etc.
#                   Examples are heap size, GC logging, JMX ports etc

So create a setenv.sh under CATALINA_BASE/bin (same dir where the catalina.sh resides). Edit the file and set the arguments to CATALINA_OPTS

For e.g. the file would look like this if you wanted to change the heap size

CATALINA_OPTS=-Xmx512m

Or in your case since you're using windows setenv.bat would be

set CATALINA_OPTS=-agentpath:C:\calltracer\jvmti\calltracer5.dll=traceFile-C:\calltracer\call.trace,filterFile-C:\calltracer\filters.txt,outputType-xml,usage-uncontrolled -Djava.library.path=C:\calltracer\jvmti -Dcalltracerlib=calltracer5

To clear the added options later just delete setenv.bat/sh

C11 timespec_get

It returns up to nanoseconds, rounded to the resolution of the implementation.

It is already implemented in Ubuntu 15.10. API looks the same as the POSIX clock_gettime.

#include <time.h>
struct timespec ts;
timespec_get(&ts, TIME_UTC);
struct timespec {
    time_t   tv_sec;        /* seconds */
    long     tv_nsec;       /* nanoseconds */

When generating CSR is possible to specify -ext attribute again to have it inserted in the CSR

keytool -certreq -file test.csr -keystore test.jks -alias testAlias -ext SAN=dns:test.example.com

Not a queue example, but extremely simple :)

class MyHouse {
    private boolean pizzaArrived = false;

    public void eatPizza(){
        synchronized(this){
            while(!pizzaArrived){
                wait();
            }
        }
        System.out.println("yumyum..");
    }

    public void pizzaGuy(){
        synchronized(this){
             this.pizzaArrived = true;
             notifyAll();
        }
    }
}

Some important points:
1) NEVER do

 if(!pizzaArrived){
     wait();
 }

Always use while(condition), because

• a) threads can sporadically awake from waiting state without being notified by anyone. (even when the pizza guy didn't ring the chime, somebody would decide try eating the pizza.).
• b) You should check for the condition again after acquiring the synchronized lock. Let's say pizza don't last forever. You awake, line-up for the pizza, but it's not enough for everybody. If you don't check, you might eat paper! :) (probably better example would be while(!pizzaExists){ wait(); }.

2) You must hold the lock (synchronized) before invoking wait/nofity. Threads also have to acquire lock before waking.

3) Try to avoid acquiring any lock within your synchronized block and strive to not invoke alien methods (methods you don't know for sure what they are doing). If you have to, make sure to take measures to avoid deadlocks.

4) Be careful with notify(). Stick with notifyAll() until you know what you are doing.

5)Last, but not least, read Java Concurrency in Practice!

Based on Daniel's answer, I wrote this SASS mixin with interpolation (#{}) for a youtube video's iframe that is inside a Bootstrap modal dialog:

@mixin responsive-modal-wiframe($height: 9, $width: 16.5,
                                $max-w-allowed: 90, $max-h-allowed: 60) {
  $sides-adjustment: 1.7;

  iframe {
    width: #{$width / $height * ($max-h-allowed - $sides-adjustment)}vh;
    height: #{$height / $width * $max-w-allowed}vw;
    max-width: #{$max-w-allowed - $sides-adjustment}vw;
    max-height: #{$max-h-allowed}vh;
  }

  @media only screen and (max-height: 480px) {
    margin-top: 5px;
    .modal-header {
      padding: 5px;
      .modal-title {font-size: 16px}
    }
    .modal-footer {display: none}
  }
}

Usage:

.modal-dialog {
  width: 95vw; // the modal should occupy most of the screen's available space
  text-align: center; // this will center the titles and the iframe

  @include responsive-modal-wiframe();
}

This will always display the video without those black parts that youtube adds to the iframe when the width or height is not proportional to the video. Notes:

• $sides-adjustment is a slight adjustment to compensate a tiny part of these black parts showing up on the sides;
• in very low height devices (< 480px) the standard modal takes up a lot of space, so I decided to:
  1. hide the .modal-footer;
  2. adjust the positioning of the .modal-dialog;
  3. reduce the sizes of the .modal-header.

After a lot of testing, this is working flawlessly for me now.

You can also do this by changing .pagination by replacing "text-align: center" with two to three lines of css for left, transform and, depending on circumstances, position.

.pagination {_x000D_
  left: 50%; /* left-align your element to center */_x000D_
  transform: translateX(-50%); /* offset left by half the width of your element */_x000D_
  position: absolute; /* use or dont' use depending on element parent */_x000D_
}_x000D_
.pagination a {_x000D_
  display: block;_x000D_
  width: 30px;_x000D_
  height: 30px;_x000D_
  float: left;_x000D_
  margin-left: 3px;_x000D_
  background: url(/images/structure/pagination-button.png);_x000D_
}_x000D_
.pagination a.last {_x000D_
  width: 90px;_x000D_
  background: url(/images/structure/pagination-button-last.png);_x000D_
}_x000D_
.pagination a.first {_x000D_
  width: 60px;_x000D_
  background: url(/images/structure/pagination-button-first.png);_x000D_
}

<div class='pagination'>_x000D_
  <a class='first' href='#'>First</a>_x000D_
  <a href='#'>1</a>_x000D_
  <a href='#'>2</a>_x000D_
  <a href='#'>3</a>_x000D_
  <a class='last' href='#'>Last</a>_x000D_

<!-- end: .pagination -->

How to debug a remote staging or production Spring Boot application

Server-side

Let's assume you have successfully followed Spring Boot's guide on setting up your Spring Boot application as a service. Your application artifact resides in /srv/my-app/my-app.war, accompanied by a configuration file /srv/my-app/my-app.conf:

# This is file my-app.conf
# What can you do in this .conf file? The my-app.war is prepended with a SysV init.d script
# (yes, take a look into the war file with a text editor). As my-app.war is symlinked in the init.d directory, that init.d script
# gets executed. One of its step is actually `source`ing this .conf file. Therefore we can do anything in this .conf file that
# we can also do in a regular shell script.

JAVA_OPTS="-agentlib:jdwp=transport=dt_socket,address=localhost:8002,server=y,suspend=n"
export SPRING_PROFILES_ACTIVE=staging

When you restart your Spring Boot application with sudo service my-app restart, then in its log file located at /var/log/my-app.log should be a line saying Listening for transport dt_socket at address: 8002.

Client-side (developer machine)

Open an SSH port-forwarding tunnel to the server: ssh -L 8002:localhost:8002 [email protected]. Keep this SSH session running.

In Eclipse, from the toolbar, select Run -> Debug Configurations -> select Remote Java Application -> click the New button -> select as Connection Type Standard (Socket Attach), as Host localhost, and as Port 8002 (or whatever you have configured in the steps before). Click Apply and then Debug.

The Eclipse debugger should now connect to the remote server. Switching to the Debug perspective should show the connected JVM and its threads. Breakpoints should fire as soon as they are remotely triggered.

It is this:

#define TRUE 1
#define FALSE 0

It turns out this is actually possible, but not using the genuine Docker CE or EE version.

You can either use Red Hat's fork of docker with the '--add-registry' flag or you can build docker from source yourself with registry/config.go modified to use your own hard-coded default registry namespace/index.

The problem you will have is with collections where unicity of elements is calculated according to both .equals() and .hashCode(), for instance keys in a HashMap.

As its name implies, it relies on hash tables, and hash buckets are a function of the object's .hashCode().

If you have two objects which are .equals(), but have different hash codes, you lose!

The part of the contract here which is important is: objects which are .equals() MUST have the same .hashCode().

This is all documented in the javadoc for Object. And Joshua Bloch says you must do it in Effective Java. Enough said.

Solution is:

while (dataGridView1.RowCount > 1)
{
    dataGridView1.Rows.RemoveAt(0);
}

There are multiple easy ways.

1. Just touch web.xml of any webapp.

   touch /usr/share/tomcat/webapps/<WEBAPP-NAME>/WEB-INF/web.xml
   

You can also update a particular jar file in WEB-INF/lib and then touch web.xml, rather than building whole war file and deploying it again.

2. Delete webapps/YOUR_WEB_APP directory, Tomcat will start deploying war within 5 seconds (assuming your war file still exists in webapps folder).

3. Generally overwriting war file with new version gets redeployed by tomcat automatically. If not, you can touch web.xml as explained above.

4. Copy over an already exploded "directory" to your webapps folder

I recently discovered a specialized class that's awesome for a bulk insert (ODP.NET). Oracle.DataAccess.Client.OracleBulkCopy! It takes a datatable as a parameter, then you call WriteTOServer method...it is very fast and effective, good luck!!

Based on the the8472 answer and https://developer.mozilla.org/en-US/docs/Web/API/Element/matches here is cross-platform 2017 solution:

if (!Element.prototype.matches) {
    Element.prototype.matches =
        Element.prototype.matchesSelector ||
        Element.prototype.mozMatchesSelector ||
        Element.prototype.msMatchesSelector ||
        Element.prototype.oMatchesSelector ||
        Element.prototype.webkitMatchesSelector ||
        function(s) {
            var matches = (this.document || this.ownerDocument).querySelectorAll(s),
                i = matches.length;
            while (--i >= 0 && matches.item(i) !== this) {}
            return i > -1;
        };
}

function findAncestor(el, sel) {
    if (typeof el.closest === 'function') {
        return el.closest(sel) || null;
    }
    while (el) {
        if (el.matches(sel)) {
            return el;
        }
        el = el.parentElement;
    }
    return null;
}

Here is a working example in both Javascript and jQuery:

http://jsfiddle.net/GuLYN/312/

//In jQuery
$("#calculate").click(function() {
    var num = parseFloat($("#textbox").val());
    var new_num = $("#textbox").val(num.toFixed(2));
});


// In javascript
document.getElementById('calculate').onclick = function() {
    var num = parseFloat(document.getElementById('textbox').value);
    var new_num = num.toFixed(2);
    document.getElementById('textbox').value = new_num;
};
?

Perhaps you might want to give Dentist JS a look? (disclaimer: I wrote the code)

code:

document.URL == "http://helloworld.com/quotes?id=1337&author=kelvin&message=hello"
var currentURL = document.URL;
var params = currentURL.extract();
console.log(params.id); // 1337
console.log(params.author) // "kelvin"
console.log(params.message) // "hello"

with Dentist JS, you can basically call the extract() function on all strings (e.g., document.URL.extract() ) and you get back a HashMap of all parameters found. It's also customizable to deal with delimiters and all.

                                        val progress = workInfo.progress.getInt(WORK_PROGRESS_VALUE, 0)
                                        progressBar?.visibility = View.VISIBLE

                                    }
                                }
                            }
                        }
                    })

        }

You could use querySelector() with attribute selector '[attribute="value"]', then affect css rule using .style, as you can see in the example below:

document.querySelector('a[aria-expanded="true"]').style.backgroundColor = "#42DCA3";

<ul><li class="active">_x000D_
  <a href="#3a" class="btn btn-default btn-lg" data-toggle="tab" aria-expanded="true"> <span class="network-name">Google+ with aria expanded true</span></a>_x000D_
  </li>_x000D_
  <li>_x000D_
    <a href="#3a" class="btn btn-default btn-lg" data-toggle="tab" aria-expanded="false"> <span class="network-name">Google+ with aria expanded false</span></a>_x000D_
  </li>_x000D_
</ul>

jQuery solution :

If you want to use a jQuery solution you could simply use css() method :

$('a[aria-expanded="true"]').css('background-color','#42DCA3');

Hope this helps.

I have stumbled across this question and I will submit my answer that I used and worked pretty well. I had a search box that filtered and array of objects and on my search box I used the (ngModelChange)="onChange($event)"

in my .html

<input type="text" [(ngModel)]="searchText" (ngModelChange)="reSearch(newValue)" placeholder="Search">

then in my component.ts

reSearch(newValue: string) {
    //this.searchText would equal the new value
    //handle my filtering with the new value
}

You can use useEffect/useLayoutEffect to achieve this:

const SomeComponent = () => {
  const [count, setCount] = React.useState(0)

  React.useEffect(() => {
    if (count > 1) {
      document.title = 'Threshold of over 1 reached.';
    } else {
      document.title = 'No threshold reached.';
    }
  }, [count]);

  return (
    <div>
      <p>{count}</p>

      <button type="button" onClick={() => setCount(count + 1)}>
        Increase
      </button>
    </div>
  );
};

More about it over here.

If you are looking for an out of the box solution, check out this custom hook that works like useState but accepts as second parameter a callback function:

// npm install use-state-with-callback

import useStateWithCallback from 'use-state-with-callback';

const SomeOtherComponent = () => {
  const [count, setCount] = useStateWithCallback(0, count => {
    if (count > 1) {
      document.title = 'Threshold of over 1 reached.';
    } else {
      document.title = 'No threshold reached.';
    }
  });

  return (
    <div>
      <p>{count}</p>

      <button type="button" onClick={() => setCount(count + 1)}>
        Increase
      </button>
    </div>
  );
};

Inspired from this post and that post, I use this code to generate and verify hashed salted passwords. It only uses JDK provided classes, no external dependency.

The process is:

• you create a salt with getNextSalt
• you ask the user his password and use the hash method to generate a salted and hashed password. The method returns a byte[] which you can save as is in a database with the salt
• to authenticate a user, you ask his password, retrieve the salt and hashed password from the database and use the isExpectedPassword method to check that the details match

/**
 * A utility class to hash passwords and check passwords vs hashed values. It uses a combination of hashing and unique
 * salt. The algorithm used is PBKDF2WithHmacSHA1 which, although not the best for hashing password (vs. bcrypt) is

This is an old post, but if IE is giving you trouble. Change your GET requests to POST and IE will no longer cache them.

I spent way too much time figuring this out the hard way. Hope it helps.

How it sounds:

out = only initialize/fill a parameter (the parameter must be empty) return it out plain

ref = reference, standard parameter (maybe with value), but the function can modifiy it.

You want to use an absolute path to the executable, and use the cwd kwarg of Popen to set the working directory. See the docs.

If cwd is not None, the child’s current directory will be changed to cwd before it is executed. Note that this directory is not considered when searching the executable, so you can’t specify the program’s path relative to cwd.

Updated code

$('a','div.res').click(function(){
  var currentAnchor = $(this);
  alert(currentAnchor.text());
  alert(currentAnchor.attr('href'));
});

I have been using the 3 dots, instead of 2. Three dots gives you a range that is open at the beginning and closed at the end, so if you do 2 queries for subsequent ranges, you can't get the same row back in both.

And, yes, always nice to use a scope!

7-Zip, it's open source, free and supports a wide range of formats.

7z.exe x myarchive.zip

I had success after using ade.exe as explained above, plus using the latest version of Chrome Canary. Apparently your desktop version of Chrome has to be higher than the version running on your Android device.

Don't pass your int as a void*, pass a int* to your int, so you can cast the void* to an int* and copy the dereferenced pointer to your int.

int x = *static_cast<int*>(arg);

Navigate to your play page:

https://play.google.com/store/apps/details?id=com.yourpackage

Using a standard HTTP GET. Now the following jQuery finds important info for you:

Current Version

$("[itemprop='softwareVersion']").text()

What's new

$(".recent-change").each(function() { all += $(this).text() + "\n"; })

Now that you can extract these information manually, simply make a method in your app that executes this for you.

public static String[] getAppVersionInfo(String playUrl) {
    HtmlCleaner cleaner = new HtmlCleaner();
    CleanerProperties props = cleaner.getProperties();
    props.setAllowHtmlInsideAttributes(true);
    props.setAllowMultiWordAttributes(true);
    props.setRecognizeUnicodeChars(true);
    props.setOmitComments(true);
    try {
        URL url = new URL(playUrl);
        URLConnection conn = url.openConnection();
        TagNode node = cleaner.clean(new InputStreamReader(conn.getInputStream()));
        Object[] new_nodes = node.evaluateXPath("//*[@class='recent-change']");
        Object[] version_nodes = node.evaluateXPath("//*[@itemprop='softwareVersion']");

        String version = "", whatsNew = "";
        for (Object new_node : new_nodes) {
            TagNode info_node = (TagNode) new_node;
            whatsNew += info_node.getAllChildren().get(0).toString().trim()
                    + "\n";
        }
        if (version_nodes.length > 0) {
            TagNode ver = (TagNode) version_nodes[0];
            version = ver.getAllChildren().get(0).toString().trim();
        }
        return new String[]{version, whatsNew};
    } catch (IOException | XPatherException e) {
        e.printStackTrace();
        return null;
    }
}

When you set maven scope as provided, it means that when the plugin runs, the actual dependencies version used will depend on the version of Apache Maven you have installed.

Please note that CSS3 viewport units (vh,vw) wouldn't play well on iOS When you scroll the page, viewport size is somehow recalculated and your size of element which uses viewport units also increases. So, actually some javascript is required.

Although in your case, just plain initialization will do, there's a trick to wrap the array into a struct (which can be initialized after declaration).

For example:

struct foo {
  GLfloat arr[10];
};
...
struct foo foo;
foo = (struct foo) { .arr = {1.0, ... } };

To center align text

input[type='text'] { text-align:center;}

To center align the textbox in the container that it sits in, apply text-align:center to the container.

You can force it to push, but please do this ONLY when you're quite sure what you are doing.

The command is:

git push -f 

Instead of retrieving the file content as a single string, it can be handy to store the content as a list of all lines the file comprises:

with open('Path/to/file', 'r') as content_file:
    content_list = content_file.read().strip().split("\n")

As can be seen, one needs to add the concatenated methods .strip().split("\n") to the main answer in this thread.

Here, .strip() just removes whitespace and newline characters at the endings of the entire file string, and .split("\n") produces the actual list via splitting the entire file string at every newline character \n.

Moreover, this way the entire file content can be stored in a variable, which might be desired in some cases, instead of looping over the file line by line as pointed out in this previous answer.

If you just want to have the log output display when you run your app then you can go into XCode4 preferences -> Alerts and click on 'Run starts' on the left hand column.

Then select 'Show Debugger' and when you run the app the NSLog output will be displayed below the editor pane.

This way you don't have to select on the 'up arrow' button at the bottom bar.

You'll need to add this to your server configuration:

AddType application/x-httpd-php .php

That is assuming you have installed PHP properly, which may not be the case since it doesn't work where it normally would immediately after installing.

It is entirely possible that you'll also have to add the php .so/.dll file to your Apache configuration using a LoadModule directive (usually in httpd.conf).

Add $filter dependency in controller.

var formatted_datetime = $filter('date')(variable_Containing_time,'yyyy-MM-dd HH:mm:ss Z')

I solved this on Windows 10 by editing an outbound firewall rule. Right click "allow" on rule "Block network access for R local user accounts in SQL Server instance MSSQLSERVER"

Screenshot from Windows 10 Firewall - Outbound rules- this is what was blocking my instance

You can also set DirectoryIndex in apache's httpd.conf file.

CentOS keeps this file in /etc/httpd/conf/httpd.conf Debian: /etc/apache2/apache2.conf

Open the file in your text editor and find the line starting with DirectoryIndex

To load landing.html as a default (but index.html if that's not found) change this line to read:

DirectoryIndex  landing.html index.html

Now it's possible and supported by all major browsers: https://developer.mozilla.org/en-US/docs/Web/API/File/File

var file = new File(["foo"], "foo.txt", {
  type: "text/plain",
});

As others have said, the SVN Book is the best place to start and a great reference once you've gotten your sea legs. Now, to your questions ...

How often do you commit? As often as one would press ctrl + s?

Often, but not as often as you press ctrl + s. It's a matter of personal taste and/or team policy. Personally I would say commit when you complete a functional piece of code, however small.

What is a Branch and what is a Tag and how do you control them?

First, trunk is where you do your active development. It is the mainline of your code. A branch is some deviation from the mainline. It could be a major deviation, like a previous release, or just a minor tweak you want to try out. A tag is a snapshot of your code. It's a way to attach a label or bookmark to a particular revision.

It's also worth mentioning that in subversion, trunk, branches and tags are only convention. Nothing stops you from doing work in tags or having branches that are your mainline, or disregarding the tag-branch-trunk scheme all together. But, unless you have a very good reason, it's best to stick with convention.

What goes into the SVN? Only Source Code or do you share other files here aswell?

Also a personal or team choice. I prefer to keep anything related to the build in my repository. That includes config files, build scripts, related media files, docs, etc. You should not check in files that need to be different on each developer's machine. Nor do you need to check in by-products of your code. I'm thinking mostly of build folders, object files, and the like.

In @Patrick McMahon's response, the second comment here ( $first_condition is false and $second_condition is true ) is not entirely accurate:

<?php if($first_condition): ?>
  /*$first_condition is true*/
  <div class="first-condition-true">First Condition is true</div>
<?php elseif($second_condition): ?>
  /*$first_condition is false and $second_condition is true*/
  <div class="second-condition-true">Second Condition is true</div>
<?php else: ?>
  /*$first_condition and $second_condition are false*/
  <div class="first-and-second-condition-false">Conditions are false</div>
<?php endif; ?>

Elseif fires whether $first_condition is true or false, as do additional elseif statements, if there are multiple.

I am no PHP expert, so I don't know whether that's the correct way to say IF this OR that ELSE that or if there is another/better way to code it in PHP, but this would be an important distinction to those looking for OR conditions versus ELSE conditions.

Source is w3schools.com and my own experience.

Yes, it's easy and possible. Define first default colors.

Console.BackgroundColor = ConsoleColor.Black;
Console.ForegroundColor = ConsoleColor.White;
Console.Clear();

Console.Clear() it's important in order to set new console colors. If you don't make this step you can see combined colors when ask for values with Console.ReadLine().

Then you can change the colors on each print:

Console.BackgroundColor = ConsoleColor.Black;
Console.ForegroundColor = ConsoleColor.Red;
Console.WriteLine("Red text over black.");

When finish your program, remember reset console colors on finish:

Console.ResetColor();
Console.Clear();

Now with netcore we have another problem if you want to "preserve" the User experience because terminal have different colors on each Operative System.

I'm making a library that solves this problem with Text Format: colors, alignment and lot more. Feel free to use and contribute.

RemoteEndPoint is a property, its type is System.Net.EndPoint which inherits from System.Net.IPEndPoint.

If you take a look at IPEndPoint's members, you'll see that there's an Address property.

If above solutions not work just one time comment the getter and setter methods of entity class and do not set the value of id.(Primary key) Then this will work.

maybe this works:

$str='\n';
echo str_replace('\n','',$str);

true, this option is not available in any version of MS ppt.Now the solution is that You put your different sized slide in other file and put a hyperlink in first file.

see HELP FOR and see the examples

or quick try this

 for /F %%a in ("AAA BBB CCC DDD EEE FFF") do echo %%c

Restarting SQL server will disconnect users. Easiest way I've found - good also if you want to take the server offline.

But for some very wierd reason the 'Take Offline' option doesn't do this reliably and can hang or confuse the management console. Restarting then taking offline works

Sometimes this is an option - if for instance you've stopped a webserver that is the source of the connections.

1. Create class Name RecyclerTouchListener.java

import android.content.Context;
import android.support.v7.widget.RecyclerView;
import android.view.GestureDetector;
import android.view.MotionEvent;
import android.view.View;

public class RecyclerTouchListener implements RecyclerView.OnItemTouchListener 
{

private GestureDetector gestureDetector;
private ClickListener clickListener;

public RecyclerTouchListener(Context context, final RecyclerView recyclerView, final ClickListener clickListener) {
    this.clickListener = clickListener;
    gestureDetector = new GestureDetector(context, new GestureDetector.SimpleOnGestureListener() {
        @Override
        public boolean onSingleTapUp(MotionEvent e) {
            return true;
        }

        @Override
        public void onLongPress(MotionEvent e) {
            View child = recyclerView.findChildViewUnder(e.getX(), e.getY());
            if (child != null && clickListener != null) {
                clickListener.onLongClick(child, recyclerView.getChildAdapterPosition(child));
            }
        }
    });
}

@Override
public boolean onInterceptTouchEvent(RecyclerView rv, MotionEvent e) {

    View child = rv.findChildViewUnder(e.getX(), e.getY());
    if (child != null && clickListener != null && gestureDetector.onTouchEvent(e)) {
        clickListener.onClick(child, rv.getChildAdapterPosition(child));
    }
    return false;
}

@Override
public void onTouchEvent(RecyclerView rv, MotionEvent e) {
}

@Override
public void onRequestDisallowInterceptTouchEvent(boolean disallowIntercept) {

}

public interface ClickListener {
    void onClick(View view, int position);

    void onLongClick(View view, int position);
}
}

2. Call RecyclerTouchListener

recycleView.addOnItemTouchListener(new RecyclerTouchListener(this, recycleView, 
new RecyclerTouchListener.ClickListener() {
    @Override
    public void onClick(View view, int position) {
        Toast.makeText(MainActivity.this,Integer.toString(position),Toast.LENGTH_SHORT).show();
    }

    @Override
    public void onLongClick(View view, int position) {

    }
}));

Although this is an old question, I had the same question when using the Standard console version. The answer can be found in the Debian Live manual under the section 10.1 Customizing the live user. It says:

It is also possible to change the default username "user" and the default password "live".

I tried the username user and password live and it did work. If you want to run commands as root you can preface each command with sudo

Also, according to some of the O'Really javascript books....(quoted)

Another reason for using literals as opposed to the Object constructor is that there is no scope resolution. Because it’s possible that you have created a local constructor with the same name, the interpreter needs to look up the scope chain from the place you are calling Object() all the way up until it finds the global Object constructor.

I solved the problem by adding an fake autocomplete name for all inputs.

$("input").attr("autocomplete", "fake-name-disable-autofill");

In the text box that contains the header, you can use an expression to get the date. Try something like

    ="Report Generation Date: " & Today()

right click in the text box in the layout view. At the bottom of the list you'll see the expression option. There you will be able to enter the code. This option will allow you to avoid adding a second textbox.

You need to do something like this:

// instantiate XmlDocument and load XML from file
XmlDocument doc = new XmlDocument();
doc.Load(@"D:\test.xml");

// get a list of nodes - in this case, I'm selecting all <AID> nodes under
// the <GroupAIDs> node - change to suit your needs
XmlNodeList aNodes = doc.SelectNodes("/Equipment/DataCollections/GroupAIDs/AID");

// loop through all AID nodes
foreach (XmlNode aNode in aNodes)
{
   // grab the "id" attribute
   XmlAttribute idAttribute = aNode.Attributes["id"];

   // check if that attribute even exists...
   if (idAttribute != null)
   {
      // if yes - read its current value
      string currentValue = idAttribute.Value;

      // here, you can now decide what to do - for demo purposes,
      // I just set the ID value to a fixed value if it was empty before
      if (string.IsNullOrEmpty(currentValue))
      {
         idAttribute.Value = "515";
      }
   }
}

// save the XmlDocument back to disk
doc.Save(@"D:\test2.xml");

Why not simply

var item = $('.field-item');
for (var i = 0; i <= item.length; i++) {
       if ($(item[i]).text() == 'someText') {
             $(item[i]).addClass('thisClass');
             //do some other stuff here
          }
     }

SELECT DISTINCT * FROM (

SELECT TOP 10 p.id, pl.nm, pl.val, pl.txt_val

from dm.labs pl
join mas_data.patients p    
  on pl.id = p.id
  where pl.nm like '%LDL%'
  and val is not null

)

I'm running Chrome version 60 and none of the previous CSS answers worked.

As Kristian Glass Said, there is no comparison between IaaS(AWS) and PaaS(Heroku, EngineYard).

PaaS basically helps developers to speed the development of app,thereby saving money and most importantly innovating their applications and business instead of setting up configurations and managing things like servers and databases. Other features buying to use PaaS is the application deployment process such as agility, High Availability, Monitoring, Scale / Descale, limited need for expertise, easy deployment, and reduced cost and development time.

But still there is a dark side to PaaS which lead barrier to PaaS adoption :

• Less Control over Server and databases
• Costs will be very high if not governed properly
• Premature and dubious in current day and age

Apart from above you should have enough skill set to mange you IaaS:

• Hardware acquisition
• Operating System
• Server Software
• Server Side Scripting Environment
• Web server
• Database Management System(Mysql, Redis etc)
• Configure production server
• Tool for testing and deployment
• Monitoring App
• High Availability
• Load Blancing/ Http Routing
• Service Backup Policies
• Team Collaboration
• Rebuild Production

If you have small scale business, PaaS will be best option for you:

• Pay as you Go
• Low start up cost
• Leave the plumbing to expert
• PaaS handles auto scaling/descaling, Load balancing, disaster recovery
• PaaS manages all security requirements
• PaaS manages reliability, High Availability
• Paas manages many third party add-ons for you

It will be totally individual choice based on requirement. You can have details on my PPT Hosting Rails Apps.

Reinstalling RVM worked for me, but I had to reinstall all of my gems afterward:

rvm implode
\curl -sSL https://get.rvm.io | bash -s stable --ruby
rvm reload

Sometimes Xcode when overrides methods adds class func instead of just func. Then in static method you can't see instance properties. It is very easy to overlook it. That was my case.

Your code "for /f "tokens=* delims=" %%x in (a.txt) do echo %%x" will work on most Windows Operating Systems unless you have modified commands.

So you could instead "cd" into the directory to read from before executing the "for /f" command to follow out the string. For instance if the file "a.txt" is located at C:\documents and settings\%USERNAME%\desktop\a.txt then you'd use the following.

cd "C:\documents and settings\%USERNAME%\desktop"
for /f "tokens=* delims=" %%x in (a.txt) do echo %%x
echo.
echo.
echo.
pause >nul
exit

But since this doesn't work on your computer for x reason there is an easier and more efficient way of doing this. Using the "type" command.

@echo off
color a
cls
cd "C:\documents and settings\%USERNAME%\desktop"
type a.txt
echo.
echo.
pause >nul
exit

Or if you'd like them to select the file from which to write in the batch you could do the following.

@echo off
:A
color a
cls
echo Choose the file that you want to read.
echo.
echo.
tree
echo.
echo.
echo.
set file=
set /p file=File:
cls
echo Reading from %file%
echo.
type %file%
echo.
echo.
echo.
set re=
set /p re=Y/N?:
if %re%==Y goto :A
if %re%==y goto :A
exit

rng.step(n=1) {| obj | block } => rng

Iterates over rng, passing each nth element to the block. If the range contains numbers or strings, natural ordering is used. Otherwise step invokes succ to iterate through range elements. The following code uses class Xs, which is defined in the class-level documentation.

range = Xs.new(1)..Xs.new(10)
range.step(2) {|x| puts x}
range.step(3) {|x| puts x}

produces:

1 x
3 xxx
5 xxxxx
7 xxxxxxx
9 xxxxxxxxx
1 x
4 xxxx
7 xxxxxxx
10 xxxxxxxxxx

You could use the function group.sum from package Rfast.

Category <- Rfast::as_integer(Category,result.sort=FALSE) # convert character to numeric. R's as.numeric produce NAs.
result <- Rfast::group.sum(Frequency,Category)
names(result) <- Rfast::Sort(unique(Category)
# 30 5 34

Rfast has many group functions and group.sum is one of them.

My experience is that there are many different csv formats. Specially how they handle escaping of quotes and delimiters within a field.

These are the variants I have ran into:

• quotes are quoted and doubled (excel) i.e. 15" -> field1,"15""",field3
• quotes are not changed unless the field is quoted for some other reason. i.e. 15" -> field1,15",fields3
• quotes are escaped with \. i.e. 15" -> field1,"15\"",field3
• quotes are not changed at all (this is not always possible to parse correctly)
• delimiter is quoted (excel). i.e. a,b -> field1,"a,b",field3
• delimiter is escaped with \. i.e. a,b -> field1,a\,b,field3

I have tried many of the existing csv parsers but there is not a single one that can handle the variants I have ran into. It is also difficult to find out from the documentation which escaping variants the parsers support.

In my projects I now use either the VB TextFieldParser or a custom splitter.

Cuando se use Windows en Español, el código debe quedar asi (when using Windows in Spanish, code is):

for /F "tokens=3 delims=: " %%H in ('sc query MYSERVICE ^| findstr "        ESTADO"') do (
  if /I "%%H" NEQ "RUNNING" (
    REM Put your code you want to execute here
    REM For example, the following line
    net start MYSERVICE
  )
)

Reemplazar MYSERVICE con el nombre del servicio que se desea procesar. Puedes ver el nombre del servicio viendo las propiedades del servicio. (Replace MYSERVICE with the name of the service to be processed. You can see the name of the service on service properties.)

if you open localhost/phpmyadmin you will find a tab called "User accounts". There you can define all your users that can access the mysql database, set their rights and even limit from where they can connect.

From your shell run:

pip2 install unicodecsv

And (unlike the original question) presuming you're using Python's built in csv module, turn
import csv into
import unicodecsv as csv in your code.

When you want to throw away a specific number of characters from the input stream manually.

A very common use case is using this to safely ignore newline characters since cin will sometimes leave newline characters that you will have to go over to get to the next line of input.

Long story short it gives you flexibility when handling stream input.

I've used this simple code in my codebase:

static public string ToReadableByteArray(byte[] bytes)
{
    return string.Join(", ", bytes);
}

To use:

Console.WriteLine(ToReadableByteArray(bytes));

Dim path As String = GetFolderPath(SpecialFolder.ApplicationData)
 Dim filepath As String = path + "\" + "your.bat"
    ' Create the file if it does not exist. 
    If File.Exists(filepath) = False Then
        File.Create(filepath)
    Else
    End If
    Dim attributes As FileAttributes
    attributes = File.GetAttributes(filepath)
    If (attributes And FileAttributes.ReadOnly) = FileAttributes.ReadOnly Then
        ' Remove from Readonly the file.
        attributes = RemoveAttribute(attributes, FileAttributes.ReadOnly)
        File.SetAttributes(filepath, attributes)
        Console.WriteLine("The {0} file is no longer RO.", filepath)
    Else
    End If
    If (attributes And FileAttributes.Hidden) = FileAttributes.Hidden Then
        ' Show the file.
        attributes = RemoveAttribute(attributes, FileAttributes.Hidden)
        File.SetAttributes(filepath, attributes)
        Console.WriteLine("The {0} file is no longer Hidden.", filepath)
    Else
    End If
    Dim sr As New StreamReader(filepath)
    Dim input As String = sr.ReadToEnd()
    sr.Close()
    Dim output As String = "@echo off"
    Dim output1 As String = vbNewLine + "your 1st cmd code"
    Dim output2 As String = vbNewLine + "your 2nd cmd code "
    Dim output3 As String = vbNewLine + "exit"
    Dim sw As New StreamWriter(filepath)
    sw.Write(output)
    sw.Write(output1)
    sw.Write(output2)
    sw.Write(output3)
    sw.Close()
    If (attributes And FileAttributes.Hidden) = FileAttributes.Hidden Then
    Else
        ' Hide the file.
        File.SetAttributes(filepath, File.GetAttributes(filepath) Or FileAttributes.Hidden)
        Console.WriteLine("The {0} file is now hidden.", filepath)
    End If
    Dim procInfo As New ProcessStartInfo(path + "\" + "your.bat")
    procInfo.WindowStyle = ProcessWindowStyle.Minimized
    procInfo.WindowStyle = ProcessWindowStyle.Hidden
    procInfo.CreateNoWindow = True
    procInfo.FileName = path + "\" + "your.bat"
    procInfo.Verb = "runas"
    Process.Start(procInfo)

it saves your .bat file to "Appdata of current user" ,if it does not exist and remove the attributes and after that set the "hidden" attributes to file after writing your cmd code and run it silently and capture all output saves it to file so if u wanna save all output of cmd to file just add your like this

code > C:\Users\Lenovo\Desktop\output.txt

just replace word "code" with your .bat file code or command and after that the directory of output file I found one code recently after searching alot if u wanna run .bat file in vb or c# or simply just add this in the same manner in which i have written

Either you can change the button type to submit

<button type="submit"  onclick="submitform()" id="save">Save</button>

Or you can hide the submit button, keep another button with type="button" and have click event for that button

<form>
    <button style="display: none;" type="submit" >Hidden button</button>
    <button type="button" onclick="submitForm()">Submit</button>
</form>

If you want to use it in plain SQL, I would let the store procedure fill a table or temp table with the resulting rows (or go for @Tony Andrews approach).
If you want to use @Thilo's solution, you have to loop the cursor using PL/SQL. Here an example: (I used a procedure instead of a function, like @Thilo did)

create or replace procedure myprocedure(retval in out sys_refcursor) is
begin
  open retval for
    select TABLE_NAME from user_tables;
end myprocedure;

 declare 
   myrefcur sys_refcursor;
   tablename user_tables.TABLE_NAME%type;
 begin
   myprocedure(myrefcur);
   loop
     fetch myrefcur into tablename;
     exit when myrefcur%notfound;
     dbms_output.put_line(tablename);
   end loop;
   close myrefcur;
 end;

Since you are using MatPaginator, you just need to do any change to paginator, this triggers data reload.

Simple trick:

this.paginator._changePageSize(this.paginator.pageSize); 

This updates the page size to the current page size, so basically nothing changes, except the private _emitPageEvent() function is called too, triggeing table reload.

I think now, the best practice is use display: inline-block;

Best practice now may be to using display: flex; flex-wrap: wrap; on div container and flex-basis: XX%; on div

look like this demo: https://jsfiddle.net/42L1emus/1/

A clean example.

<?php
    header('Content-Type: application/download');
    header('Content-Disposition: attachment; filename="example.txt"');
    header("Content-Length: " . filesize("example.txt"));

    $fp = fopen("example.txt", "r");
    fpassthru($fp);
    fclose($fp);
?>

Your guess is right: the code is trying to evaluate x**3+2*x-4 immediately. Unfortunately you can't really prevent it from doing so. The good news is that in Python, functions are first-class objects, by which I mean that you can treat them like any other variable. So to fix your function, we could do:

import numpy as np  
import matplotlib.pyplot as plt  

def graph(formula, x_range):  
    x = np.array(x_range)  
    y = formula(x)  # <- note now we're calling the function 'formula' with x
    plt.plot(x, y)  
    plt.show()  

def my_formula(x):
    return x**3+2*x-4

graph(my_formula, range(-10, 11))

If you wanted to do it all in one line, you could use what's called a lambda function, which is just a short function without a name where you don't use def or return:

graph(lambda x: x**3+2*x-4, range(-10, 11))

And instead of range, you can look at np.arange (which allows for non-integer increments), and np.linspace, which allows you to specify the start, stop, and the number of points to use.

Although bash has a return statement, the only thing you can specify with it is the function's own exit status (a value between 0 and 255, 0 meaning "success"). So return is not what you want.

You might want to convert your return statement to an echo statement - that way your function output could be captured using $() braces, which seems to be exactly what you want.

Here is an example:

function fun1(){
  echo 34
}

function fun2(){
  local res=$(fun1)
  echo $res
}

Another way to get the return value (if you just want to return an integer 0-255) is $?.

function fun1(){
  return 34
}

function fun2(){
  fun1
  local res=$?
  echo $res
}

Also, note that you can use the return value to use boolean logic like fun1 || fun2 will only run fun2 if fun1 returns a non-0 value. The default return value is the exit value of the last statement executed within the function.

The best practise is to not force a garbage collection in most cases. (Every system I have worked on that had forced garbage collections, had underlining problems that if solved would have removed the need to forced the garbage collection, and sped the system up greatly.)

There are a few cases when you know more about memory usage then the garbage collector does. This is unlikely to be true in a multi user application, or a service that is responding to more then one request at a time.

However in some batch type processing you do know more then the GC. E.g. consider an application that.

• Is given a list of file names on the command line
• Processes a single file then write the result out to a results file.
• While processing the file, creates a lot of interlinked objects that can not be collected until the processing of the file have complete (e.g. a parse tree)
• Does not keep much state between the files it has processed.

You may be able to make a case (after careful) testing that you should force a full garbage collection after you have process each file.

Another cases is a service that wakes up every few minutes to process some items, and does not keep any state while it’s asleep. Then forcing a full collection just before going to sleep may be worthwhile.

The only time I would consider forcing a collection is when I know that a lot of object had been created recently and very few objects are currently referenced.

I would rather have a garbage collection API when I could give it hints about this type of thing without having to force a GC my self.

Javascript document.getElementById("<%=contrilid.ClientID%>").value; or using jquery

$("#<%= txt_iplength.ClientID %>").val();

There are some great answers, but many use functions that are flagged as not cryptographically secure. If you want a random 6 digit number that is cryptographically secure you can use something like this:

$key = random_int(0, 9999999);
$key = str_pad($key, 6, 0, STR_PAD_LEFT);
return $key;

This will also include numbers like 000182 and others that would otherwise be excluded from the other examples.

You'll probably find you're setting the date to Feb 31, 2009 (if today is Jan 31) and Javascript automagically rolls that into the early part of March.

Check the day of the month, I'd expect it to be 1, 2 or 3. If it's not the same as before you added a month, roll back by one day until the month changes again.

That way, the day "last day of Jan" becomes "last day of Feb".

EDIT:

Ronald, based on your comments to other answers, you might want to steer clear of edge-case behavior such as "what happens when I try to make Feb 30" or "what happens when I try to make 2009/13/07 (yyyy/mm/dd)" (that last one might still be a problem even for my solution, so you should test it).

Instead, I would explicitly code for the possibilities. Since you don't care about the day of the month (you just want the year and month to be correct for next month), something like this should suffice:

var now = new Date();
if (now.getMonth() == 11) {
    var current = new Date(now.getFullYear() + 1, 0, 1);
} else {
    var current = new Date(now.getFullYear(), now.getMonth() + 1, 1);
}

That gives you Jan 1 the following year for any day in December and the first day of the following month for any other day. More code, I know, but I've long since grown tired of coding tricks for efficiency, preferring readability unless there's a clear requirement to do otherwise.

++ This worked for me. It's vanilla javascirpt and good for use cases such as de-cluttering when testing with ngMocks library:

<!-- specRunner.html - keep this at the top of your <script> asset loading so that it is available readily -->
<!--  Frienly tip - have all JSON files in a json-data folder for keeping things organized-->
<script src="json-data/findByIdResults.js" charset="utf-8"></script>
<script src="json-data/movieResults.js" charset="utf-8"></script>

This is your javascript file that contains the JSON data

// json-data/JSONFindByIdResults.js
var JSONFindByIdResults = {
     "Title": "Star Wars",
     "Year": "1983",
     "Rated": "N/A",
     "Released": "01 May 1983",
     "Runtime": "N/A",
     "Genre": "Action, Adventure, Sci-Fi",
     "Director": "N/A",
     "Writer": "N/A",
     "Actors": "Harrison Ford, Alec Guinness, Mark Hamill, James Earl Jones",
     "Plot": "N/A",
     "Language": "English",
     "Country": "USA",
     "Awards": "N/A",
     "Poster": "N/A",
     "Metascore": "N/A",
     "imdbRating": "7.9",
     "imdbVotes": "342",
     "imdbID": "tt0251413",
     "Type": "game",
     "Response": "True"
};

Finally, work with the JSON data anywhere in your code

// working with JSON data in code
var findByIdResults = window.JSONFindByIdResults;

Note:- This is great for testing and even karma.conf.js accepts these files for running tests as seen below. Also, I recommend this only for de-cluttering data and testing/development environment.

// extract from karma.conf.js
files: [
     'json-data/JSONSearchResultHardcodedData.js',
     'json-data/JSONFindByIdResults.js'
     ...
]

Hope this helps.

UPDATE

An easier way that worked for me is just include a function at the bottom of the code returning whatever JSON.

// within test code
let movies = getMovieSearchJSON();
.....
...
...
....
// way down below in the code
function getMovieSearchJSON() {
      return {
         "Title": "Bri Squared",
         "Year": "2011",
         "Rated": "N/A",
         "Released": "N/A",
         "Runtime": "N/A",
         "Genre": "Comedy",
         "Director": "Joy Gohring",
         "Writer": "Briana Lane",
         "Actors": "Brianne Davis, Briana Lane, Jorge Garcia, Gabriel Tigerman",
         "Plot": "N/A",
         "Language": "English",
         "Country": "USA",
         "Awards": "N/A",
         "Poster": "http://ia.media-imdb.com/images/M/MV5BMjEzNDUxMDI4OV5BMl5BanBnXkFtZTcwMjE2MzczNQ@@._V1_SX300.jpg",
         "Metascore": "N/A",
         "imdbRating": "8.2",
         "imdbVotes": "5",
         "imdbID": "tt1937109",
         "Type": "movie",
         "Response": "True"
   }
}

DECLARE @temp as nvarchar(20)

I found a solution that works on jQuery 3.4.1 slim

After un-minifying, add {passive: true} to the addEventListener function on line 1567 like so:

t.addEventListener(p, a, {passive: true}))

Nothing breaks and lighthouse audits don't complain about the listeners.

Something as simple as changing port from 5432 to 5433 worked for me.

Here answer for your code as whole:

key =10

files = ("ME%i.txt" % i for i in range(key))

#opening
files = [ open(filename, 'w') for filename in files]

# processing
for i, file in zip(range(key),files):
    file.write(str(i))
# closing
for openfile in files:
    openfile.close()

I'll give you the simplest and most effective piece of advice I think anybody could give you: code.

You can only be better at using a language (which implies understanding it) by coding. You have to actively enjoy coding, be inspired, ask questions, and find answers by yourself.

Got a an hour to spare? Write code that will reverse a string, and find out the most optimum solution. A free evening? Why not try some web-scraping. Read other peoples code. See how they do things. Ask yourself what you would do.

When I'm bored at my computer, I open my IDE and code-storm. I jot down ideas that sound interesting, and challenging. An URL shortener? Sure, I can do that. Oh, I learnt how to convert numbers from one base to another as a side effect!

This is valid whatever your skill level. You never stop learning. By actively coding in your spare time you will, with little additional effort, come to understand the language, and ultimately, become a guru. You will build up knowledge and reusable code and memorise idioms.

I have been working on this for some time now. Tough to get right, and I don't claim I do, but I'm happy with it so far. My code and several demos can be found at

• https://github.com/bauerca/drag-sort-listview

Its use is very similar to the TouchInterceptor (on which the code is based), although significant implementation changes have been made.

DragSortListView has smooth and predictable scrolling while dragging and shuffling items. Item shuffles are much more consistent with the position of the dragging/floating item. Heterogeneous-height list items are supported. Drag-scrolling is customizable (I demonstrate rapid drag scrolling through a long list---not that an application comes to mind). Headers/Footers are respected. etc.?? Take a look.

These answers are all very good, but I wanted to share another thing I discovered on stackoverflow that is really quite useful, here is the direct link

Basically, @DidzisElferts shows how you can get all the colours, coordinates, etc that ggplot uses to build a plot you created. Very nice!

p <- ggplot(mpg,aes(x=class,fill=class)) + geom_bar()
ggplot_build(p)$data
[[1]]
     fill  y count x ndensity ncount  density PANEL group ymin ymax xmin xmax

5 #00B6EB 33    33 5        1      1 1.111111     1     5    0   33 4.55 5.45
6 #A58AFF 35    35 6        1      1 1.111111     1     6    0   35 5.55 6.45
7 #FB61D7 62    62 7        1      1 1.111111     1     7    0   62 6.55 7.45

In case you want to apply common functions such as sum or mean, you should use rowSums or rowMeans since they're faster than apply(data, 1, sum) approach. Otherwise, stick with apply(data, 1, fun). You can pass additional arguments after FUN argument (as Dirk already suggested):

set.seed(1)
m <- matrix(round(runif(20, 1, 5)), ncol=4)
diag(m) <- NA
m
     [,1] [,2] [,3] [,4]
[1,]   NA    5    2    3
[2,]    2   NA    2    4
[3,]    3    4   NA    5
[4,]    5    4    3   NA
[5,]    2    1    4    4

Then you can do something like this:

apply(m, 1, quantile, probs=c(.25,.5, .75), na.rm=TRUE)
    [,1] [,2] [,3] [,4] [,5]
25%  2.5    2  3.5  3.5 1.75
50%  3.0    2  4.0  4.0 3.00
75%  4.0    3  4.5  4.5 4.00

Here is a NuGet plugin called Cassette, which among other things provides you the ability to reference scripts and styles in partials.

Though there are a number of configurations available for this plugin, which makes it highly flexible. Here is the simplest way of referring script or stylesheet files:

Bundles.Reference("scripts/app");

According to the documentation:

Calls to Reference can appear anywhere in a page, layout or partial view.

The path argument can be one of the following:

• A bundle path
• An asset path - the whole bundle containing this asset is referenced
• A URL

If you are inserting keys that are comparable but not int-like, you could potentially override the comparison operators on them (i.e. <= become > and > becomes <=). Otherwise, you can override heapq._siftup in the heapq module (it's all just Python code, in the end).

What should I do to prepare my website for https. (Do I need to alter the code / Config)

You should keep best practices for secure coding in mind (here is a good intro: http://www.owasp.org/index.php/Secure_Coding_Principles ), otherwise all you need is a correctly set up SSL certificate.

Is SSL and https one and the same..

Pretty much, yes.

Do I need to apply with someone to get some license or something.

You can buy an SSL certificate from a certificate authority or use a self-signed certificate. The ones you can purchase vary wildly in price - from $10 to hundreds of dollars a year. You would need one of those if you set up an online shop, for example. Self-signed certificates are a viable option for an internal application. You can also use one of those for development. Here's a good tutorial on how to set up a self-signed certificate for IIS: Enabling SSL on IIS 7.0 Using Self-Signed Certificates

Do I need to make all my pages secured or only the login page..

Use HTTPS for everything, not just the initial user login. It's not going to be too much of an overhead and it will mean the data that the users send/receive from your remotely hosted application cannot be read by outside parties if it is intercepted. Even Gmail now turns on HTTPS by default.

Conversion Operators (also known as User Defined Conversions)

In C++ you can create conversion operators, operators that allow the compiler to convert between your types and other defined types. There are two types of conversion operators, implicit and explicit ones.

Implicit Conversion Operators (C++98/C++03 and C++11)

An implicit conversion operator allows the compiler to implicitly convert (like the conversion between int and long) the value of a user-defined type to some other type.

The following is a simple class with an implicit conversion operator:

class my_string {
public:
  operator const char*() const {return data_;} // This is the conversion operator
private:
  const char* data_;
};

Implicit conversion operators, like one-argument constructors, are user-defined conversions. Compilers will grant one user-defined conversion when trying to match a call to an overloaded function.

void f(const char*);

my_string str;
f(str); // same as f( str.operator const char*() )

At first this seems very helpful, but the problem with this is that the implicit conversion even kicks in when it isn’t expected to. In the following code, void f(const char*) will be called because my_string() is not an lvalue, so the first does not match:

void f(my_string&);
void f(const char*);

f(my_string());

Beginners easily get this wrong and even experienced C++ programmers are sometimes surprised because the compiler picks an overload they didn’t suspect. These problems can be mitigated by explicit conversion operators.

Explicit Conversion Operators (C++11)

Unlike implicit conversion operators, explicit conversion operators will never kick in when you don't expect them to. The following is a simple class with an explicit conversion operator:

class my_string {
public:
  explicit operator const char*() const {return data_;}
private:
  const char* data_;
};

Notice the explicit. Now when you try to execute the unexpected code from the implicit conversion operators, you get a compiler error:

prog.cpp: In function ‘int main()’:
prog.cpp:15:18: error: no matching function for call to ‘f(my_string)’
prog.cpp:15:18: note: candidates are:
prog.cpp:11:10: note: void f(my_string&)
prog.cpp:11:10: note:   no known conversion for argument 1 from ‘my_string’ to ‘my_string&’
prog.cpp:12:10: note: void f(const char*)
prog.cpp:12:10: note:   no known conversion for argument 1 from ‘my_string’ to ‘const char*’

To invoke the explicit cast operator, you have to use static_cast, a C-style cast, or a constructor style cast ( i.e. T(value) ).

However, there is one exception to this: The compiler is allowed to implicitly convert to bool. In addition, the compiler is not allowed to do another implicit conversion after it converts to bool (a compiler is allowed to do 2 implicit conversions at a time, but only 1 user-defined conversion at max).

Because the compiler will not cast "past" bool, explicit conversion operators now remove the need for the Safe Bool idiom. For example, smart pointers before C++11 used the Safe Bool idiom to prevent conversions to integral types. In C++11, the smart pointers use an explicit operator instead because the compiler is not allowed to implicitly convert to an integral type after it explicitly converted a type to bool.

I wrote this to remove all objects apart from functions from the current environment (Programming language used is R with IDE R-Studio):

    remove_list=c()                             # create a vector

      for(i in 1:NROW(ls())){                   # repeat over all objects in environment
        if(class(get(ls()[i]))!="function"){    # if object is *not* a function
         remove_list=c(remove_list,ls()[i])     # ..add to vector remove_list
         }    
      }

    rm(list=remove_list)                        # remove all objects named in remove_list

Notes-

The argument "list" in rm(list=) must be a character vector.

The name of an object in position i of the current environment is returned from ls()[i] and the object itself from get(ls()[i]). Therefore the class of an object is returned from class(get(ls()[i]))

Yes, you can use SQL IN operator to search multiple absolute values:

SELECT name FROM products WHERE name IN ( 'Value1', 'Value2', ... );

If you want to use LIKE you will need to use OR instead:

SELECT name FROM products WHERE name LIKE '%Value1' OR name LIKE '%Value2';

Using AND (as you tried) requires ALL conditions to be true, using OR requires at least one to be true.

One possible idea is to write separate constructor function

//Something is the structure we work with
type Something struct {
     Text string 
     DefaultText string 
} 
// NewSomething create new instance of Something
func NewSomething(text string) Something {
   something := Something{}
   something.Text = text
   something.DefaultText = "default text"
   return something
}

If you want to update any specific version from the package.json you can update the version of the package by doing ==>

yarn add package-name@version-number

or

npm install --save package-name@version-number

If you want to update all packages to the latest version you can run command ==>

npm audit fix --force

C99 defines "%zd" etc. for that. (thanks to the commenters) There is no portable format specifier for that in C++ - you could use %p, which woulkd word in these two scenarios, but isn't a portable choice either, and gives the value in hex.

Alternatively, use some streaming (e.g. stringstream) or a safe printf replacement such as Boost Format. I understand that this advice is only of limited use (and does require C++). (We've used a similar approach fitted for our needs when implementing unicode support.)

The fundamental problem for C is that printf using an ellipsis is unsafe by design - it needs to determine the additional argument's size from the known arguments, so it can't be fixed to support "whatever you got". So unless your compiler implement some proprietary extensions, you are out of luck.

First you need to make sure if both of your files are in the same working directory. Next, you can import the whole file. For example,

import myClass

or you can import the entire class and entire functions from the file. For example,

from myClass import

Finally, you need to create an instance of the class from the original file and call the instance objects.

In Java, there are no multi-dimension arrays. There are arrays of arrays. So:

int[][] array = new int[2][3];

It actually consists of two arrays, each has three elements.

Compile this in your database and start using boolean statements in your querys.

note: the function get's a varchar2 param, so be sure to wrap any "strings" in your statement. It will return 1 for true and 0 for false;

select bool('''abc''<''bfg''') from dual;

CREATE OR REPLACE function bool(p_str in varchar2) return varchar2 
 is
 begin

 execute immediate ' begin if '||P_str||' then
          :v_res :=  1;
       else
          :v_res :=  0;
       end if; end;' using out v_res;

       return v_res;

 exception 
  when others then 
    return '"'||p_str||'" is not a boolean expr.';
 end;
/

var res = exitDictionary
            .Select(p => p.Value).Cast<Dictionary<string, object>>()
            .SelectMany(d => d)
            .Where(p => p.Key == "fieldname1")
            .Select(p => p.Value).Cast<List<Dictionary<string,string>>>()
            .SelectMany(l => l)
            .SelectMany(d=> d)
            .Where(p => p.Key == "valueTitle")
            .Select(p => p.Value)
            .ToList();

This also works, and easy to understand.

Put this in your CSS:

white-space:nowrap;

Get more information here: http://www.w3.org/wiki/CSS/Properties/white-space

white-space

The white-space property declares how white space inside the element is handled.

Values

normal This value directs user agents to collapse sequences of white space, and break lines as necessary to fill line boxes.

pre This value prevents user agents from collapsing sequences of white space. Lines are only broken at newlines in the source, or at occurrences of "\A" in generated content.

nowrap This value collapses white space as for 'normal', but suppresses line breaks within text.

pre-wrap This value prevents user agents from collapsing sequences of white space. Lines are broken at newlines in the source, at occurrences of "\A" in generated content, and as necessary to fill line boxes.

pre-line This value directs user agents to collapse sequences of white space. Lines are broken at newlines in the source, at occurrences of "\A" in generated content, and as necessary to fill line boxes.

inherit Takes the same specified value as the property for the element's parent.

One possible cause for an item not responding to an event is when the item is overlapped by another. In that case, you may have to set a higher z-index for the item you wish to click on.

At first you need to understand first, that Tomcat is a Java application. So, to see which java version Tomcat is using, you can just simply find the script file from which Tomcat is started, usually catalina.sh.

Inside this file, you will get something like below:

catalina.sh:#   JAVA_HOME       Must point at your Java Development Kit installation.
catalina.sh:#                   Defaults to JAVA_HOME if empty.
catalina.sh:  [ -n "$JAVA_HOME" ] && JAVA_HOME=`cygpath --unix "$JAVA_HOME"`
catalina.sh:  JAVA_HOME=`cygpath --absolute --windows "$JAVA_HOME"`
catalina.sh:    echo "Using JAVA_HOME:       $JAVA_HOME"

By default, JAVA_HOME should be empty, which mean it will use the default version of java, or you can test with: echo $JAVA_HOME

And then use "java -version" to see which version you default java is.

And vice versa by setting this property: JAVA_HOME, you can configure which Java version to use when starting Tomcat.

If you don't really need to embed them in your app, though - you can just require Acrobat Reader or FoxIt (or bundle it, if it meets their respective licensing terms) and shell out to it. It's not as cool, but it gets the job done for free.

Regular expressions work well if needing to find a range of starting characters. The following finds all employee names starting with A, B, C or D and adds the “UPPER” call in case a name is in the database with a starting lowercase letter. My query works in Oracle (I did not test other DB's). The following would return for example:
Adams
adams
Dean
dean

This query also ignores case in the ORDER BY via the "lower" call:

SELECT employee_name 
FROM employees
WHERE REGEXP_LIKE(UPPER(TRIM(employee_name)), '^[A-D]')
ORDER BY lower(employee_name)

You could try this:

SELECT * 
FROM table 
ORDER BY (c_counts+f_counts) 
LIMIT 20

The raw_input() function reads a line from input (i.e. the user) and returns a string

Python v3.x as raw_input() was renamed to input()

PEP 3111: raw_input() was renamed to input(). That is, the new input() function reads a line from sys.stdin and returns it with the trailing newline stripped. It raises EOFError if the input is terminated prematurely. To get the old behavior of input(), use eval(input()).

These samples work well. You can check section and then return a height to show or hide section. Don't forget to extend your viewcontroller from UITableViewDelegate.

Objective-C

- (CGFloat)tableView:(UITableView *)tableView heightForFooterInSection:(NSInteger)section
{
    if (section == 0)
    {
        // to hide footer for section 0 
        return 0.0;
    }
    else
    {
        // show footer for every section except section 0 
        return HEIGHT_YOU_WANT;
    }
}

- (UIView *)tableView:(UITableView *)tableView viewForFooterInSection:(NSInteger)section
{
    UIView *footerView = [[UIView alloc] init];
    footerView.backgroundColor = [UIColor blackColor];
    return footerView;
}

Swift

func tableView(_ tableView: UITableView, viewForFooterInSection section: Int) -> UIView? {
    let footerView = UIView()
    footerView.backgroundColor = UIColor.black
    return footerView
}

func tableView(_ tableView: UITableView, heightForFooterInSection section: Int) -> CGFloat {
    if section == 0 {
        // to hide footer for section 0
        return 0.0
    } else {
        // show footer for every section except section 0
        return HEIGHT_YOU_WANT
    }
}

My suggestion is just to start - pick a small project that you would generally use to learn an MVC-style language (i.e. something with a database, maybe some basic workflow), and then as you need to learn a concept, use one (or both!) of

Agile Web Development with Rails or The Rails Way

to learn about how it works, and then try it.

The problems with Agile Web Development are that it's outdated, and that the scenario runs on too long for you really to want to build it once; The Rails Way can be hard to follow as it bounces from reference to learning, but when it's good, it's better than Agile Web Development.

But overall they're both good books, and they're both good for learning, but neither of them provide an "education" path that you'll want to follow. So I read a few chapters of the former (enough to get the basic concepts and learn how to bootstrap the first app - there are some online articles that help with this as well) and then just got started, and then every few days I read about something new or I use the books to understand something.

One more thing: both books are much more Rails books than they are Ruby books, and if you're going to write clean code, it's worth spending a day learning Ruby syntax as early as possible. Why's Guide to Ruby is a good one, there are others as well.

This worked for me:

File >> Project Structure >> Modules >> Dependency >> + (on left-side of window)

clicking the "+" sign will let you designate the directory where you have unpacked JavaFX's "lib" folder.

Scope is Compile (which is the default.) You can then edit this to call it JavaFX by double-clicking on the line.

then in:

Run >> Edit Configurations

Add this line to VM Options:

--module-path /path/to/JavaFX/lib --add-modules=javafx.controls

(oh and don't forget to set the SDK)

On CentOS Linux release 7.5.1804, we were able to make this work by editing /etc/selinux/config and changing the setting of SELINUX like so:

SELINUX=disabled

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"/>

Guid.NewGuid(), as it creates GUIDs as intended.

Guid.NewGuid() creates an empty Guid object, initializes it by calling CoCreateGuid and returns the object.

new Guid() merely creates an empty GUID (all zeros, I think).

I guess they had to make the constructor public as Guid is a struct.

If you use Spring you can:

1) create a log4j configuration file, e.g. "/WEB-INF/classes/log4j-myapp.properties" DO NOT name it "log4j.properties"

Example:

log4j.rootLogger=ERROR, stdout, rollingFile

log4j.appender.stdout=org.apache.log4j.ConsoleAppender
log4j.appender.stdout.layout=org.apache.log4j.PatternLayout
log4j.appender.stdout.layout.ConversionPattern=%d %p [%c] - <%m>%n

log4j.appender.rollingFile=org.apache.log4j.RollingFileAppender
log4j.appender.rollingFile.File=${myWebapp-instance-root}/WEB-INF/logs/application.log
log4j.appender.rollingFile.MaxFileSize=512KB
log4j.appender.rollingFile.MaxBackupIndex=10
log4j.appender.rollingFile.layout=org.apache.log4j.PatternLayout
log4j.appender.rollingFile.layout.ConversionPattern=%d %p [%c] - %m%n
log4j.appender.rollingFile.Encoding=UTF-8

We'll define "myWebapp-instance-root" later on point (3)

2) Specify config location in web.xml:

<context-param>
  <param-name>log4jConfigLocation</param-name>
  <param-value>/WEB-INF/classes/log4j-myapp.properties</param-value>
</context-param>

3) Specify a unique variable name for your webapp's root, e.g. "myWebapp-instance-root"

<context-param>
  <param-name>webAppRootKey</param-name>
  <param-value>myWebapp-instance-root</param-value>
</context-param>

4) Add a Log4jConfigListener:

<listener>
  <listener-class>org.springframework.web.util.Log4jConfigListener</listener-class>
</listener>

If you choose a different name, remember to change it in log4j-myapp.properties, too.

UPDATE (2009/08/01) I've translated my article to English: http://www.megadix.it/node/136

What if your server goes down at 4:59AM and comes back at 5:01AM? I think it will just skip the run. I would recommend persistent scheduler like Quartz, that would store its schedule data somewhere. Then it will see that this run hasn't been performed yet and will do it at 5:01AM.

To pass the value you must included the hidden value value="hiddenValue" in the <input> statement like so:

<input type="hidden" id="thisField" name="inputName" value="hiddenValue">

Then you recuperate the hidden form value in the same way that you recuperate the value of visible input fields, by accessing the parameter of the request object. Here is an example:

This code goes on the page where you want to hide the value.

<form action="anotherPage.jsp" method="GET">
    <input type="hidden" id="thisField" name="inputName" value="hiddenValue">
<input type="submit">   
</form>

Then on the 'anotherPage.jsp' page you recuperate the value by calling the getParameter(String name) method of the implicit request object, as so:

<% String hidden = request.getParameter("inputName"); %>
The Hidden Value is <%=hidden %>

The output of the above script will be:

The Hidden Value is hiddenValue
