When you write the statement

*src = "anotherstring";

the compiler sees the constant string "abcdefghijklmnop" like an array. Imagine you had written the following code instead:

char otherstring[14] = "anotherstring";
...
*src = otherstring;

Now, it's a bit clearer what is going on. The left-hand side, *src, refers to a char (since src is of type pointer-to-char) whereas the right-hand side, otherstring, refers to a pointer.

This isn't strictly forbidden because you may want to store the address that a pointer points to. However, an explicit cast is normally used in that case (which isn't too common of a case). The compiler is throwing up a red flag because your code is likely not doing what you think it is.

It appears to me that you are trying to assign a string. Strings in C aren't data types like they are in C++ and are instead implemented with char arrays. You can't directly assign values to a string like you are trying to do. Instead, you need to use functions like strncpy and friends from <string.h> and use char arrays instead of char pointers. If you merely want the pointer to point to a different static string, then drop the *.

Its a very old question but I think it will help newbies line me who are learning python. If you have Python 3.4 or above, the pathlib library comes with the default distribution.

To use it, you just pass a path or filename into a new Path() object using forward slashes and it handles the rest. To indicate that the path is a raw string, put r in front of the string with your actual path.

For example,

from pathlib import Path

dataFolder = Path(r'D:\Desktop dump\example.txt')

Since the existing answers were written, Xcode's interface has been updated and they're no longer correct (notably the Click on Window, Organiser // Expand the Teams section step). Now the instructions for importing an existing certificate are as follows:

To export selected certificates

1. Choose Xcode > Preferences.
2. Click Accounts at the top of the window.
3. Select the team you want to view, and click View Details.
4. Control-click the certificate you want to export in the Signing Identities table and choose Export from the pop-up menu.

5. Enter a filename in the Save As field and a password in both the Password and Verify fields. The file is encrypted and password protected.
6. Click Save. The file is saved to the location you specified with a .p12 extension.

Source (Apple's documentation)

To import it, I found that Xcode's let-me-help-you menu didn't recognise the .p12 file. Instead, I simply imported it manually into Keychain, then Xcode built and archived without complaining.

This regex extracts an element from a comma separated list, regardless of contents:

(.+?)(?:,|$)

If you just replace the comma with something else, it should work for any delimiter.

I'm using json lib from http://json-lib.sourceforge.net/

    m.put("email_content","test email content");

    //generate JSON Object
    JSONObject json = JSONObject.fromObject(content);
    String message = json.toString();
    ...

If the program was written in C# you can get the source code in almost its original form using .NET Reflector. You won't be able to see comments and local variable names, but it is very readable.

If it was written C++ it's not so easy... even if you could decompile the code into valid C++ it is unlikely that it will resemble the original source because of inlined functions and optimizations which are hard to reverse.

Please note that by reverse engineering and modifying the source code you might breaking the terms of use of the programs unless you wrote them yourself or have permission from the author.

This is perfectly legal:

public static void main(String[] args) {

}

public static void main(String argv) {

Let me know if this works. Way to detect an Apple device (Mac computers, iPhones, etc.) with help from StackOverflow.com:
What is the list of possible values for navigator.platform as of today?

var deviceDetect = navigator.platform;
var appleDevicesArr = ['MacIntel', 'MacPPC', 'Mac68K', 'Macintosh', 'iPhone', 
'iPod', 'iPad', 'iPhone Simulator', 'iPod Simulator', 'iPad Simulator', 'Pike 
v7.6 release 92', 'Pike v7.8 release 517'];

// If on Apple device
if(appleDevicesArr.includes(deviceDetect)) {
    // Execute code
}
// If NOT on Apple device
else {
    // Execute code
}

This is the solution I found with threads and standard libraries

Loop keeps going on until one key is pressed
Returns the key pressed as a single character string

Works in Python 2.7 and 3

import thread
import sys

def getch():
    import termios
    import sys, tty
    def _getch():
        fd = sys.stdin.fileno()
        old_settings = termios.tcgetattr(fd)
        try:
            tty.setraw(fd)
            ch = sys.stdin.read(1)
        finally:
            termios.tcsetattr(fd, termios.TCSADRAIN, old_settings)
        return ch
    return _getch()

def input_thread(char):
    char.append(getch())

def do_stuff():
    char = []
    thread.start_new_thread(input_thread, (char,))
    i = 0
    while not char :
        i += 1

    print "i = " + str(i) + " char : " + str(char[0])

do_stuff()

easiest way is to just use this

document.getElementById("mySelect").value = "banana";

myselect is name of your dropdown banana is just one of items in your dropdown list

IEquatable<T> can be a much easier way to do this with modern frameworks.

You get a nice simple bool Equals(T other) function and there's no messing around with casting or creating a separate class.

public class Person : IEquatable<Person>
{
    public Person(string name, string hometown)
    {
        this.Name = name;
        this.Hometown = hometown;
    }

    public string Name { get; set; }
    public string Hometown { get; set; }

    // can't get much simpler than this!
    public bool Equals(Person other)
    {
        return this.Name == other.Name && this.Hometown == other.Hometown;
    }

    public override int GetHashCode()
    {
        return Name.GetHashCode();  // see other links for hashcode guidance 
    }
}

Note you DO have to implement GetHashCode if using this in a dictionary or with something like Distinct.

PS. I don't think any custom Equals methods work with entity framework directly on the database side (I think you know this because you do AsEnumerable) but this is a much simpler method to do a simple Equals for the general case.

If things don't seem to be working (such as duplicate key errors when doing ToDictionary) put a breakpoint inside Equals to make sure it's being hit and make sure you have GetHashCode defined (with override keyword).

You could cast it to DECIMAL and specify the scale to be 2 digits

decimal and numeric

So, something like

DECLARE @i AS FLOAT = 2
SELECT @i / 3
SELECT CAST(@i / 3 AS DECIMAL(18,2))

in Java JDBC API makes everything with databases. using JDBC we can write Java applications to
1. Send queries or update SQL to DB(any relational Database) 2. Retrieve and process the results from DB

with below three steps we can able to retrieve data from any Database

Statement stmt = con.createStatement();
ResultSet rs = stmt.executeQuery("SELECT a, b, c FROM Table");

while (rs.next()) {
    int x = rs.getInt("a");
    String s = rs.getString("b");
    float f = rs.getFloat("c");
}

You can use...

document.getElementById('theForm').submit();

...but don't replace the innerHTML. You could hide the form and then insert a processing... span which will appear in its place.

var form = document.getElementById('theForm');

form.style.display = 'none';

var processing = document.createElement('span');

processing.appendChild(document.createTextNode('processing ...'));

form.parentNode.insertBefore(processing, form);

The other posters are correct: you need to iterate the list and copy into a new list.

However... If the objects in the list are immutable - you don't need to clone them. If your object has a complex object graph - they will need to be immutable as well.

The other benefit of immutability is that they are threadsafe as well.

A simple, fast way to get the content by id :

echo get_post_field('post_content', $id);

And if you want to get the content formatted :

echo apply_filters('the_content', get_post_field('post_content', $id));

Works with pages, posts & custom posts.

In addition to the awesome answers above, 2 more points may be added:

1. Semantic difference:

Promises may be already resolved upon creation. This means they guarantee conditions rather than events. If they are resolved already, the resolved function passed to it is still called.

Conversely, callbacks handle events. So, if the event you are interested in has happened before the callback has been registered, the callback is not called.

2. Inversion of control

Callbacks involve inversion of control. When you register a callback function with any API, the Javascript runtime stores the callback function and calls it from the event loop once it is ready to be run.

Refer The Javascript Event loop for an explanation.

With Promises, control resides with the calling program. The .then() method may be called at any time if we store the promise object.

I got the following UIAlertView initialization code to compile without errors (I thing the last, varyadic part is tricky perhaps). But I had to make sure the class of self (which I am passing as the delegate) was adopting the UIAlertViewDelegate protocol for the compile errors to go away:

let alertView = UIAlertView(
                  title: "My Title",
                  message: "My Message",
                  delegate: self,
                  cancelButtonTitle: "Cancel",
                  otherButtonTitles: "OK"
                )

By the way, this is the error I was getting (as of Xcode 6.4):

Cannot find an initializer for type 'UIAlertView' that accepts an argument list of type '(title: String, message: String, delegate: MyViewController, cancelButtonTitle: String, otherButtonTitles: String)'

As others mentioned, you should migrate to UIAlertController if you can target iOS 8.x+. To support iOS 7, use the code above (iOS 6 is not supported by Swift).

I prefer using the glob module, as it does pattern matching and expansion.

import glob
print(glob.glob("/home/adam/*.txt"))

It will return a list with the queried files:

['/home/adam/file1.txt', '/home/adam/file2.txt', .... ]

Once upon a time I needed to do this, and the only cross-browser reliable solution I came across was hack job. I'm not the biggest fan of solutions like this, but it certainly produces the correct result time and time again.

The idea is that you clone the element, remove any bounding width, and test if the cloned element is wider than the original. If so, you know it's going to have been truncated.

For example, using jQuery:

var $element = $('#element-to-test');
var $c = $element
           .clone()
           .css({display: 'inline', width: 'auto', visibility: 'hidden'})
           .appendTo('body');

if( $c.width() > $element.width() ) {
    // text was truncated. 
    // do what you need to do
}

$c.remove();

I made a jsFiddle to demonstrate this, http://jsfiddle.net/cgzW8/2/

You could even create your own custom pseudo-selector for jQuery:

$.expr[':'].truncated = function(obj) {
  var $this = $(obj);
  var $c = $this
             .clone()
             .css({display: 'inline', width: 'auto', visibility: 'hidden'})
             .appendTo('body');

  var c_width = $c.width();
  $c.remove();

  if ( c_width > $this.width() )
    return true;
  else
    return false;
};

Then use it to find elements

$truncated_elements = $('.my-selector:truncated');

Demo: http://jsfiddle.net/cgzW8/293/

Hopefully this helps, hacky as it is.

Since most modern CPUs support virtualization natively, the reason you received such message can be because virtualization is turned off on your machine. For example, that was the case on my HP laptop - the factory setting for hardware virtualization was "Disabled". So, go to your machine's BIOS and enable virtualization.

Please note that you will most likely need an index on that column too.

class AddUserReferenceToTester < ActiveRecord::Migration
  def change
    add_column :testers, :user_id, :integer
    add_index  :testers, :user_id
  end

The id of the input seems is not WallSearch. Maybe you're confusing that name and id. They are two different properties. name is used to define the name by which the value is posted, while id is the unique identification of the element inside the DOM.

Other possibility is that you have two elements with the same id. The browser will pick any of these (probably the last, maybe the first) and return an element that doesn't support the value property.

One way to add permanent path, which worked for me, is:

cd /etc/profile.d
touch custom.sh
vi custom.sh 
export PATH=$PATH:/path according to your setting/

Restart your computer and here we go; path will be there permanently.

I was struggling with the same problem and found one solution. I guess it can help you. when you run python manage.py runserver, it will take 127.0.0.1 as default ip address and 8000. 127.0.0.0 is the same as localhost which can be accessed locally. to access it from cross origin you need to run it on your system ip or 0.0.0.0. 0.0.0.0 can be accessed from any origin in the network. for port number, you need to set inbound and outbound policy of your system if you want to use your own port number not the default one.

To do this you need to run server with command python manage.py runserver 0.0.0.0:<your port> as mentioned above

or, set a default ip and port in your python environment. For this see my answer on django change default runserver port

I'm on Angular 6, Typescript 2.7, and I'm using Jest framework to unit test. I had @types/jest installed and added on typeRoots inside tsconfig.json

But still have the display error below (i.e: on terminal there is no errors)

cannot find name describe

And adding the import :

import {} from 'jest'; // in my case or jasmine if you're using jasmine

doesn't technically do anything, so I thought, that there is an import somewhere causing this problem, then I found, that if delete the file

tsconfig.spec.json

in the src/ folder, solved the problem for me. As @types is imported before inside the rootTypes.

I recommend you to do same and delete this file, no needed config is inside. (ps: if you're in the same case as I am)

The computer "name" is resolved from the IP address by the underlying DNS (Domain Name System) library of the OS. There's no universal concept of a computer name across OSes, but DNS is generally available. If the computer name hasn't been configured so DNS can resolve it, it isn't available.

Call "setWarningMsg()" Method and pass the text that you want to show.

exm:- setWarningMsg("thank you for using java");


public static void setWarningMsg(String text){
    Toolkit.getDefaultToolkit().beep();
    JOptionPane optionPane = new JOptionPane(text,JOptionPane.WARNING_MESSAGE);
    JDialog dialog = optionPane.createDialog("Warning!");
    dialog.setAlwaysOnTop(true);
    dialog.setVisible(true);
}

Or Just use

JOptionPane optionPane = new JOptionPane("thank you for using java",JOptionPane.WARNING_MESSAGE);
JDialog dialog = optionPane.createDialog("Warning!");
dialog.setAlwaysOnTop(true); // to show top of all other application
dialog.setVisible(true); // to visible the dialog

You can use JOptionPane. (WARNING_MESSAGE or INFORMATION_MESSAGE or ERROR_MESSAGE)

Keep in mind that String.format() and DecimalFormat produce string using default Locale. So they may write formatted number with dot or comma as a separator between integer and decimal parts. To make sure that rounded String is in the format you want use java.text.NumberFormat as so:

  Locale locale = Locale.ENGLISH;
  NumberFormat nf = NumberFormat.getNumberInstance(locale);
  // for trailing zeros:
  nf.setMinimumFractionDigits(2);
  // round to 2 digits:
  nf.setMaximumFractionDigits(2);

  System.out.println(nf.format(.99));
  System.out.println(nf.format(123.567));
  System.out.println(nf.format(123.0));

Will print in English locale (no matter what your locale is): 0.99 123.57 123.00

The example is taken from Farenda - how to convert double to String correctly.

Here is a method that is supported by nearly all browsers:

if (sessionStorage.getItem('reloaded') != null) {
    console.log('page was reloaded');
} else {
    console.log('page was not reloaded');
}

sessionStorage.setItem('reloaded', 'yes'); // could be anything

It uses SessionStorage to check if the page is opened the first time or if it is refreshed.

any(d)

This will return true if the dict. d contains at least one truelike key, false otherwise.

Example:

any({0:'test'}) == False

another (more general) way is to check the number of items:

len(d)

When the user enters information in a form and clicks Submit , there are two ways the information can be sent from the browser to the server: in the URL, or within the body of the HTTP request.

The GET method, which was used in the example earlier, appends name/value pairs to the URL. Unfortunately, the length of a URL is limited, so this method only works if there are only a few parameters. The URL could be truncated if the form uses a large number of parameters, or if the parameters contain large amounts of data. Also, parameters passed on the URL are visible in the address field of the browser not the best place for a password to be displayed.

The alternative to the GET method is the POST method. This method packages the name/value pairs inside the body of the HTTP request, which makes for a cleaner URL and imposes no size limitations on the forms output. It is also more secure.

StopWatch class looks for your best solution.

Stopwatch sw = Stopwatch.StartNew();
DoSomeWork();

Also it has a static field called Stopwatch.IsHighResolution. Of course, this is a hardware and operating system issue.

Indicates whether the timer is based on a high-resolution performance counter.

Like urupvog's answer, make sure that you aren't running any other virtual machines like VirtualBox. When I restarted my computer, AVD worked until I started Vagrant for backend development (then it wouldn't launch).

Use OnCommand event of imagebutton. Within it do

<asp:Button id="Button1" Text="Click" CommandName="Something" CommandArgument="your command arg" OnCommand="CommandBtn_Click" runat="server"/>

{    
    switch(e.CommandName)
    {
        case "Something":
            // Do your code
            break;
        default:              
            break; 

    }
}

Use this query:

UPDATE `table` SET date_date=now();

Sample code can be:

<?php
$con = mysql_connect("localhost","peter","abc123");
if (!$con)
  {
  die('Could not connect: ' . mysql_error());
  }

mysql_select_db("my_db", $con);

mysql_query("UPDATE `table` SET date_date=now()");

mysql_close($con);
?>

For SQL Server 2012 and later versions, the best method is @MajidBasirati's answer.

I also loved @CarlosToledo's answer, it's not limited to any SQL Server version but it's missing Order By Clauses. Without them, it may return wrong results.

For SQL Server 2008 and later I would use Common Table Expressions for better performance.

FROM MY_TABLE
    INNER JOIN MyCTE ON (MyCTE.Id <> MY_TABLE.Id) 
ORDER BY Id

Django 2.1.1 The primary answer got me halfway to answering my question. It did not help me save the result to a field in my actual model. In my case I wanted a textfield that a user could enter data into, then when a save occurred the data would be processed and the result put into a field in the model and saved. While the original answer showed how to get the value from the extra field, it did not show how to save it back to the model at least in Django 2.1.1

This takes the value from an unbound custom field, processes, and saves it into my real description field:

class WidgetForm(forms.ModelForm):
    extra_field = forms.CharField(required=False)

    def processData(self, input):
        # example of error handling
        if False:
            raise forms.ValidationError('Processing failed!')

        return input + " has been processed"

    def save(self, commit=True):
        extra_field = self.cleaned_data.get('extra_field', None)

        # self.description = "my result" note that this does not work

        # Get the form instance so I can write to its fields
        instance = super(WidgetForm, self).save(commit=commit)

        # this writes the processed data to the description field
        instance.description = self.processData(extra_field)

        if commit:
            instance.save()

        return instance

    class Meta:
        model = Widget
        fields = "__all__"

This can be the message you receive even when custom errors is turned off in web.config file. It can mean you have run out of free space on the drive that hosts the application. Clean your log files if you have no other space to gain on the drive.

the URL is also encrypted, you really only have the IP, Port and if SNI, the host name that are unencrypted.

create model.ts in your component directory as below

export module DataModel {
       export interface DataObjectName {
         propertyName: type;
        }
       export interface DataObjectAnother {
         propertyName: type;
        }
    }

then in your component import above as, import {DataModel} from './model';

export class YourComponent {
   public DataObject: DataModel.DataObjectName;
}

your DataObject should have all the properties from DataObjectName.

So this may not be the issue for you, but I was struggling with this error. I discovered what was causing my problem, though I can't really explain as to why.

For me, mysqli_connect was working fine where the connection was made on pages in any various sub-directory. For some reason though, the same code referenced on pages in the root directory was returning this error. The strange thing is that it was working fine on my localhost environment in MAMP in the root directory, however on my shared host it was not.

After struggling to figure out what was giving me "Error 500" white screen from this "PHP Fatal Error," I went through the code and stumbled upon this code in the error handling that was suggested by the PHP Manual (https://www.php.net/manual/en/mysqli.error.php).

if (!mysqli_query($link, "SET a=1")) {
    printf("Error message: %s\n", mysqli_error($link));
}

I randomly decided to remove it and, voila, connection to the database working in root directories. Maybe someone smarter than me can explain this, for anyone struggling with a similar issue.

If you use jQuery built-in after() with empty value it will create a dynamic object that will match your :after CSS selector.

$('.active').after().click(function () {
    alert('clickable!');
});

See the jQuery documentation.

In the constructor of

 public class ErrorEventArg : EventArgs

You have to add "base" as follows:

    public ErrorEventArg(string errorMsg, string lastQuery) : base (string errorMsg, string lastQuery)
    {
        ErrorMsg = errorMsg;
        LastQuery = lastQuery;
    }

That solved it for me

SearchDialog or SearchWidget ?

When it comes to implement a search functionality there are two suggested approach by official Android Developer Documentation.
You can either use a SearchDialog or a SearchWidget.
I am going to explain the implementation of Search functionality using SearchWidget.

How to do it with Search widget ?

I will explain search functionality in a RecyclerView using SearchWidget. It's pretty straightforward.

Just follow these 5 Simple steps

1) Add searchView item in the menu

You can add SearchView can be added as actionView in menu using

app:useActionClass = "android.support.v7.widget.SearchView" .

<menu xmlns:android="http://schemas.android.com/apk/res/android"
   xmlns:app="http://schemas.android.com/apk/res-auto"
   xmlns:tools="http://schemas.android.com/tools"
   tools:context="rohksin.com.searchviewdemo.MainActivity">
   <item
       android:id="@+id/searchBar"
       app:showAsAction="always"
       app:actionViewClass="android.support.v7.widget.SearchView"
   />
</menu>

2) Set up SerchView Hint text, listener etc

You should initialize SearchView in the onCreateOptionsMenu(Menu menu) method.

  @Override
  public boolean onCreateOptionsMenu(Menu menu) {
     // Inflate the menu; this adds items to the action bar if it is present.
        getMenuInflater().inflate(R.menu.menu_main, menu);

        MenuItem searchItem = menu.findItem(R.id.searchBar);

        SearchView searchView = (SearchView) searchItem.getActionView();
        searchView.setQueryHint("Search People");
        searchView.setOnQueryTextListener(this);
        searchView.setIconified(false);

        return true;
   }

3) Implement SearchView.OnQueryTextListener in your Activity

OnQueryTextListener has two abstract methods

1. onQueryTextSubmit(String query)
2. onQueryTextChange(String newText

So your Activity skeleton would look like this

YourActivity extends AppCompatActivity implements SearchView.OnQueryTextListener{

     public boolean onQueryTextSubmit(String query)

     public boolean onQueryTextChange(String newText) 

}

4) Implement SearchView.OnQueryTextListener

You can provide the implementation for the abstract methods like this

public boolean onQueryTextSubmit(String query) {

    // This method can be used when a query is submitted eg. creating search history using SQLite DB

    Toast.makeText(this, "Query Inserted", Toast.LENGTH_SHORT).show();
    return true;
}

@Override
public boolean onQueryTextChange(String newText) {

    adapter.filter(newText);
    return true;
}

5) Write a filter method in your RecyclerView Adapter.

Most important part. You can write your own logic to perform search.
Here is mine. This snippet shows the list of Name which contains the text typed in the SearchView

public void filter(String queryText)
{
    list.clear();

    if(queryText.isEmpty())
    {
       list.addAll(copyList);
    }
    else
    {

       for(String name: copyList)
       {
           if(name.toLowerCase().contains(queryText.toLowerCase()))
           {
              list.add(name);
           }
       }

    }

   notifyDataSetChanged();
}

Just use;

$('#selectedDueDate').val(dateText).trigger('input');

It says "POST not supported", so the request is not calling your servlet. If I were you, I will issue a GET (e.g. access using a browser) to the exact URL you are issuing your POST request, and see what you get. I bet you'll see something unexpected.

You can use the function outer() to generate it.

Have a look at the demo for the function persp(), which is a base graphics function to draw perspective plots for surfaces.

Here is their first example:

x <- seq(-10, 10, length.out = 50)  
y <- x  
rotsinc <- function(x,y) {
    sinc <- function(x) { y <- sin(x)/x ; y[is.na(y)] <- 1; y }  
    10 * sinc( sqrt(x^2+y^2) )  
}

z <- outer(x, y, rotsinc)  
persp(x, y, z)

The same applies to surface3d():

require(rgl)  
surface3d(x, y, z)

I encountered same problem in opening android React Native Project in Android Studio.

The root cause is I opened the root folder of React Native Project instead of android folder of the React Native Project.

Reopen the project under android folder of React Native Project solved my problem.

Static memory allocation: The compiler allocates the required memory space for a declared variable.By using the address of operator,the reserved address is obtained and this address may be assigned to a pointer variable.Since most of the declared variable have static memory,this way of assigning pointer value to a pointer variable is known as static memory allocation. memory is assigned during compilation time.

Dynamic memory allocation: It uses functions such as malloc( ) or calloc( ) to get memory dynamically.If these functions are used to get memory dynamically and the values returned by these functions are assingned to pointer variables, such assignments are known as dynamic memory allocation.memory is assined during run time.

No, there isn't.

I'm pretty sure there is no way to intercept a click on the refresh button from JS, and even if there was, JS can be turned off.

You should probably step back from your X (preventing refreshing) and find a different solution to Y (whatever that might be).

use os.path.join() to construct your paths - It's neater:

import os
import sys
rootdir = sys.argv[1]
for root, subFolders, files in os.walk(rootdir):
    for folder in subFolders:
        outfileName = os.path.join(root,folder,"py-outfile.txt")
        folderOut = open( outfileName, 'w' )
        print "outfileName is " + outfileName
        for file in files:
            filePath = os.path.join(root,file)
            toWrite = open( filePath).read()
            print "Writing '" + toWrite + "' to" + filePath
            folderOut.write( toWrite )
        folderOut.close()

You can edit Rprofile in the base library (in 'C:/Program Files/R.Files/library/base/R' by default) to include code to be run on startup. Append

########        User code        ########
.libPaths('C:/my/dir')

to Rprofile using any text editor (like Notepad) to cause R to add 'C:/my/dir' to the list of libraries it knows about.

(Notepad can't save to Program Files, so save your edited Rprofile somewhere else and then copy it in using Windows Explorer.)

You could insert both the key,value pair and its inverse into your map structure, but would have to convert the Integer to a string:

map.put("theKey", "theValue");
map.put("theValue", "theKey");

Using map.get("theValue") will then return "theKey".

It's a quick and dirty way that I've made constant maps, which will only work for a select few datasets:

• Contains only 1 to 1 pairs
• Set of values is disjoint from the set of keys (1->2, 2->3 breaks it)

If you want to keep <Integer, String> you could maintain a second <String, Integer> map to "put" the value -> key pairs.

Check out the range documentation, you have to define a negative step:

>>> range(10, 0, -1)
[10, 9, 8, 7, 6, 5, 4, 3, 2, 1]

I was able to reduce my gradle build from 43 seconds down to 25 seconds on my old core2duo laptop (running linux mint) by adding the following to the gradle.properties file in android studio

org.gradle.parallel=true
org.gradle.daemon=true

source on why the daemon setting makes builds faster: https://www.timroes.de/2013/09/12/speed-up-gradle/

I collected some information on the internet and prepared the script that requires no external tool: See my response here. Hope it's helpful.

You also can use in this form:

<a href="@Url.Action("Information", "Admin", null)"> Admin</a>

sys_guid() is a poor option, as other answers have mentioned. One way to generate UUIDs and avoid sequential values is to generate random hex strings yourself:

select regexp_replace(
    to_char(
        DBMS_RANDOM.value(0, power(2, 128)-1),
        'FM0xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx'),
    '([a-f0-9]{8})([a-f0-9]{4})([a-f0-9]{4})([a-f0-9]{4})([a-f0-9]{12})',
    '\1-\2-\3-\4-\5') from DUAL;

The CRCRLF is known as result of a Windows XP notepad word wrap bug.

For future reference, here's an extract of relevance from the linked blog:

When you press the Enter key on Windows computers, two characters are actually stored: a carriage return (CR) and a line feed (LF). The operating system always interprets the character sequence CR LF the same way as the Enter key: it moves to the next line. However when there are extra CR or LF characters on their own, this can sometimes cause problems.

There is a bug in the Windows XP version of Notepad that can cause extra CR characters to be stored in the display window. The bug happens in the following situation:

If you have the word wrap option turned on and the display window contains long lines that wrap around, then saving the file causes Notepad to insert the characters CR CR LF at each wrap point in the display window, but not in the saved file.

The CR CR LF characters can cause oddities if you copy and paste them into other programs. They also prevent Notepad from properly re-wrapping the lines if you resize the Notepad window.

You can remove the CR CR LF characters by turning off the word wrap feature, then turning it back on if desired. However, the cursor is repositioned at the beginning of the display window when you do this.

CORS issue can be simply resolved by following this:

Create a new shortcut of Google Chrome(update browser installation path accordingly) with following value:

"C:\Program Files (x86)\Google\Chrome\Application\chrome.exe" --disable-web-security --user-data-dir="D:\chrome\temp"

Probably I have found myself:

ConnectivityManager connectivityManager = (ConnectivityManager)getSystemService(Context.CONNECTIVITY_SERVICE);
return connectivityManager.getActiveNetworkInfo().isConnectedOrConnecting();

p $eax works as of GDB 7.7.1

As of GDB 7.7.1, the command you've tried works:

set $eax = 0
p $eax
# $1 = 0
set $eax = 1
p $eax
# $2 = 1

This syntax can also be used to select between different union members e.g. for ARM floating point registers that can be either floating point or integers:

p $s0.f
p $s0.u

From the docs:

Any name preceded by ‘$’ can be used for a convenience variable, unless it is one of the predefined machine-specific register names.

and:

You can refer to machine register contents, in expressions, as variables with names starting with ‘$’. The names of registers are different for each machine; use info registers to see the names used on your machine.

But I haven't had much luck with control registers so far: OSDev 2012 http://f.osdev.org/viewtopic.php?f=1&t=25968 || 2005 feature request https://www.sourceware.org/ml/gdb/2005-03/msg00158.html || alt.lang.asm 2013 https://groups.google.com/forum/#!topic/alt.lang.asm/JC7YS3Wu31I

java packages are base, and javax packages are extensions.

Swing was an extension because AWT was the original UI API. Swing came afterwards, in version 1.1.

Another option is using eval and parse, as in

d = 5
for (i in 1:10){
     eval(parse(text = paste('a', 1:10, ' = d + rnorm(3)', sep='')[i]))
}

Instead of using any library, easiest solution till the new version comes out is to just open b.android.com/74772. You'll easily find the best solution known to date there.

PS: b.android.com/74772#c50 worked for me

If you're using it in several different places, you should turn it into a plugin.

jQuery.fn.fadeOutAndRemove = function(speed){
    $(this).fadeOut(speed,function(){
        $(this).remove();
    })
}

And then:

// Somewhere in the program code.
$('div').fadeOutAndRemove('fast');

Around 1:51 in the video, notice how she puts a <script> tag in there? The way it works is like this:

Create an html file (that's just a text file with a .html ending) somewhere on your computer. In the same folder that you put index.html, put a javascript file (that's just a textfile with a .js ending - let's call it game.js). Then, in your index.html file, put some html that includes the script tag with game.js, like Mary did in the video. index.html should look something like this:

<html>
    <head>
        <script src="game.js"></script>
    </head>
</html>

Now, double click on that file in finder, and it should open it up in your browser. To open up the console to see the output of your javascript code, hit Command-alt-j (those three buttons at the same time).

Good luck on your journey, hope it's as fun for you as it has been for me so far :)

[Context] In a virtual machine of WinXP.

You can do it with a sub-query:

SELECT * FROM (
    SELECT * FROM table ORDER BY id DESC LIMIT 50
) sub
ORDER BY id ASC

This will select the last 50 rows from table, and then order them in ascending order.

Note: you should use the accepted answer if possible. It's better than mine.

It's quite easy with the GD library.

It's built in usually, you probably have it (use phpinfo() to check)

$image = imagecreatefromjpeg("http://images.websnapr.com/?size=size&key=Y64Q44QLt12u&url=http://google.com");

imagejpeg($image, "folder/file.jpg");

The above answer is better (faster) for most situations, but with GD you can also modify it in some form (cropping for example).

$image = imagecreatefromjpeg("http://images.websnapr.com/?size=size&key=Y64Q44QLt12u&url=http://google.com");
imagecopy($image, $image, 0, 140, 0, 0, imagesx($image), imagesy($image));
imagejpeg($image, "folder/file.jpg");

This only works if allow_url_fopen is true (it is by default)

You can still use angular.isDefined()

You just need to set

$rootScope.angular = angular;

To get the last element of an array, use:

$lastElement = array_slice($array, -1)[0];

Benchmark

I iterated 1,000 times, grabbing the last element of small and large arrays that contained 100 and 50,000 elements, respectively.

Method: $array[count($array)-1];
Small array (s): 0.000319957733154
Large array (s): 0.000526905059814
Note: Fastest!  count() must access an internal length property.
Note: This method only works if the array is naturally-keyed (0, 1, 2, ...).

Method: array_slice($array, -1)[0];
Small array (s): 0.00145292282104
Large array (s): 0.499367952347

Method: array_pop((array_slice($array, -1, 1)));
Small array (s): 0.00162816047668

I used PHP Version 5.5.32.

Both result.class.to_s and result.class.name work.

Simplest Explanation:

Module is like a big container containing one or many small containers called Component, Service, Pipe

A Component contains :

• HTML template or HTML code

• Code(TypeScript)

• Service: It is a reusable code that is shared by the Components so that rewriting of code is not required

• Pipe: It takes in data as input and transforms it to the desired output

Cast the dtype of the col to str and you can perform vectorised slicing calling str:

In [29]:
df['new_col'] = df['First'].astype(str).str[0]
df

Out[29]:
   First  Second new_col
0    123     234       1
1     22    4353       2
2     32     355       3
3    453     453       4
4     45     345       4
5    453     453       4
6     56      56       5

if you need to you can cast the dtype back again calling astype(int) on the column

If you don't want to create another migration-file for a small, recent change - from Rails Console:

ActiveRecord::Migration.change_column :profiles, :show_attribute, :boolean, :default => true

Then exit and re-enter rails console, so DB-Changes will be in-effect. Then, if you do this ...

Profile.new()

You should see the "show_attribute" default-value as true.

For existing records, if you want to preserve existing "false" settings and only update "nil" values to your new default:

Profile.all.each{|profile| profile.update_attributes(:show_attribute => (profile.show_attribute == nil ? true : false))  }

Update the migration that created this table, so any future builds of the DB will get it right from the onset. Also run the same process on any deployed-instances of the DB.

If using the "new db migration" method, you can do the update of existing nil-values in that migration.

modulus is remainders system.

So 7 % 5 = 2.

5 % 7 = 5

3 % 7 = 3

2 % 7 = 2

1 % 7 = 1

When used inside a function to determine the array index. Is it safe programming ? That is a different question. I guess.

This simple approach reads the requirements file from setup.py. It is a variation of the answer by Dmitiry S.. This answer is compatible only with Python 3.6+.

Per D.S., requirements.txt can document concrete requirements with specific version numbers, whereas setup.py can document abstract requirements with loose version ranges.

Below is an excerpt of my setup.py.

import distutils.text_file
from pathlib import Path
from typing import List

def _parse_requirements(filename: str) -> List[str]:
    """Return requirements from requirements file."""
    # Ref: https://stackoverflow.com/a/42033122/
    return distutils.text_file.TextFile(filename=str(Path(__file__).with_name(filename))).readlines()

setup(...
      install_requires=_parse_requirements('requirements.txt'),
   ...)

Note that distutils.text_file.TextFile will strip comments. Also, per my experience, you apparently do not need to take any special step to bundle in the requirements file.

string1.equals(string2) is the way.

It returns true if string1 is equals to string2 in value. Else, it will return false.

equals reference

I think you need use List or classes based on that.

For instance,

ArrayList<Integer> integers = new ArrayList<Integer>();
int j;

do{
    integers.add(int.nextInt());
    j++;
}while( (integers.get(j-1) >= 1) || (integers.get(j-1) <= 100) );

You could read this article for getting more information about how to use that.

The exponential function is e^x where e is a mathematical constant called Euler's number, approximately 2.718281. This value has a close mathematical relationship with pi and the slope of the curve e^x is equal to its value at every point. np.exp() calculates e^x for each value of x in your input array.

Like everybody's saying, they're pretty much entirely different.

However, if you need a scripting language for your Java application, Javascript is actually a really good choice. There are ways to get Javascript running in the JVM and you can access and manipulate Java classes pretty seamlessly once you do.

The answers in this topic are all great. However i'd like to propose another one. Most likely you have been given an api and want that into your c# project. Using Postman, you can setup and test the api call there and once it runs properly, you can simply click 'Code' and the request that you have been working on, is written to a c# snippet. like this:

var client = new RestClient("https://api.XXXXX.nl/oauth/token");
client.Timeout = -1;
var request = new RestRequest(Method.POST);
request.AddHeader("Authorization", "Basic   N2I1YTM4************************************jI0YzJhNDg=");
request.AddHeader("Content-Type", "application/x-www-form-urlencoded");
request.AddHeader("Content-Type", "application/x-www-form-urlencoded");
request.AddParameter("grant_type", "password");
request.AddParameter("username", "[email protected]");
request.AddParameter("password", "XXXXXXXXXXXXX");
IRestResponse response = client.Execute(request);
Console.WriteLine(response.Content);

The code above depends on the nuget package RestSharp, which you can easily install.

A better solution is to use &

"dev": "npm run start-watch & npm run wp-server"

Curl does that by default without any parameters or flags, I would use it for your purposes:

curl $url > /dev/null 2>&1

Curl is more about streams and wget is more about copying sites based on this comparison.

I had this problem and the problem was bootstrap.js wasn't load in Yii2 framework.First check is jquery loaded in inspect and then check bootstrap.js is loaded?If you used any tooltip Popper.js is needed before bootsrap.js.

Fairly late to this party, but I came across this issue myself today at work. Here is how I solved the issue.

I was accessing a 3rd party API to retrieve a list of books. The object returned a massive JSON object containing roughly 20+ fields, of which I only needed the ID as a List string object. I used linq on the dynamic object to retrieve the specific field I needed and then inserted it into my List string object.

dynamic content = JsonConvert.DeserializeObject(requestContent);
var contentCodes = ((IEnumerable<dynamic>)content).Where(p => p._id != null).Select(p=>p._id).ToList();

List<string> codes = new List<string>();

foreach (var code in contentCodes)
{
    codes.Add(code?.ToString());
}

To save others a few seconds, and to save them from having to read the manual, here's the short answer. Add this to the top of your make file:

.DEFAULT_GOAL := mytarget

mytarget will now be the target that is run if "make" is executed and no target is specified.

If you have an older version of make (<= 3.80), this won't work. If this is the case, then you can do what anon mentions, simply add this to the top of your make file:

.PHONY: default
default: mytarget ;

References: https://www.gnu.org/software/make/manual/html_node/How-Make-Works.html

Based on my Comment here is one way to get what you want done:

Start byt selecting any cell in your range and Press Ctrl + T

This will give you this pop up:

make sure the Where is your table text is correct and click ok you will now have:

Now If you add a column header in D it will automatically be added to the table all the way to the last row:

Now If you enter a formula into this column:

After you enter it, the formula will be auto filled all the way to last row:

Now if you add a new row at the next row under your table:

Once entered it will be resized to the width of your table and all columns with formulas will be added also:

Hope this solves your problem!

cout is in std namespace, you shall use std::cout in your code. And you shall not add using namespace std; in your header file, it's bad to mix your code with std namespace, especially don't add it in header file.

Swift 4 API Request Example

Make use of JSONDecoder().decode

See this video JSON parsing with Swift 4

struct Post: Codable {
    let userId: Int
    let id: Int
    let title: String
    let body: String
}

URLSession.shared.dataTask(with: URL(string: "https://jsonplaceholder.typicode.com/posts")!) { (data, response, error) in

    guard let response = response as? HTTPURLResponse else {
        print("HTTPURLResponse error")
        return
    }

    guard 200 ... 299 ~= response.statusCode else {
        print("Status Code error \(response.statusCode)")
        return
    }

    guard let data = data else {
        print("No Data")
        return
    }

    let posts = try! JSONDecoder().decode([Post].self, from: data)
    print(posts)      
}.resume()

An alternative approach:

If

• your YAML structure has well defined fields to be used by your app
• AND you may freely add additional fields that won't mess up with your app

then

• at any level you may add a new block text field named like "Description" or "Comment" or "Notes" or whatever

Example:

Instead of

# This comment
# is too long

use

Description: >
  This comment
  is too long

or

Comment: >
    This comment is also too long
    and newlines survive from parsing!

More advantages:

1. If the comments become large and complex and have a repeating pattern, you may promote them from plain text blocks to objects
2. Your app may -in the future- read or update those comments

If you're looking for a JS version (using a combination of feature detection and UA sniffing) of what html5 boilerplate used to do:

var IE = (!! window.ActiveXObject && +(/msie\s(\d+)/i.exec(navigator.userAgent)[1])) || NaN;
if (IE < 9) {
    document.documentElement.className += ' lt-ie9' + ' ie' + IE;
}

Visual Basic, C#, and C++ all have syntax for accessing the Item property without using its name. Instead, the variable containing the List is used as if it were an array.

List[index]

See for instance: https://msdn.microsoft.com/en-us/library/0ebtbkkc(v=vs.110).aspx

You should use UNION if you want to combine different resultsets. Try the following:

(SELECT * 
 FROM ( SELECT * 
        FROM orders_products 
        INNER JOIN orders ON orders_products.orders_id = orders.orders_id  
        WHERE products_id = 181) AS A)
UNION 

(SELECT * 
 FROM ( SELECT * 
        FROM orders_products 
        INNER JOIN orders ON orders_products.orders_id = orders.orders_id 
        WHERE products_id = 180) AS B
ON A.orders_id=B.orders_id)

You can use StringBuilder:

    StringBuilder sb = new StringBuilder();
    sb.append('a');
    sb.append('b');
    sb.append('c');
    String str = sb.toString()

Or if you already have the characters, you can pass a character array to the String constructor:

String str = new String(new char[]{'a', 'b', 'c'});

If it is asked if it is possible (not MUST), it can ask "a" to return a random number. It would be true if it generates 1, 2, and 3 sequentially.

with({_x000D_
  get a() {_x000D_
    return Math.floor(Math.random()*4);_x000D_
  }_x000D_
}){_x000D_
  for(var i=0;i<1000;i++){_x000D_
    if (a == 1 && a == 2 && a == 3){_x000D_
      console.log("after " + (i+1) + " trials, it becomes true finally!!!");_x000D_
      break;_x000D_
    }_x000D_
  }_x000D_
}

You have it right. The stack pointer points to the top item on the stack and the base pointer points to the "previous" top of the stack before the function was called.

When you call a function, any local variable will be stored on the stack and the stack pointer will be incremented. When you return from the function, all the local variables on the stack go out of scope. You do this by setting the stack pointer back to the base pointer (which was the "previous" top before the function call).

Doing memory allocation this way is very, very fast and efficient.

As usual, create an SSH key and paste the public key to GitHub. Add the private key to ssh-agent. (I assume this is what you have done.)

To check everything is correct, use ssh -T [email protected]

Next, don't forget to modify the remote point as follows:

git remote set-url origin [email protected]:username/your-repository.git

You can do

int sum = lst.stream().filter(o -> o.getField() > 10).mapToInt(o -> o.getField()).sum();

or (using Method reference)

int sum = lst.stream().filter(o -> o.getField() > 10).mapToInt(Obj::getField).sum();

You can use the excellent jquery-Json plugin:

http://code.google.com/p/jquery-json/

Makes it easy to convert to and from Json objects.

I had to put backslash at the end of path and it worked for me.

Earlier I was using

C:\Program Files\Java\jdk1.7.0_79

just by putting "\" at the end, worked for me. Now the value of the JAVA_HOME variable is

C:\Program Files\Java\jdk1.7.0_79\

Readify made a very complete answer. Yet, I wanted to add the End statement, you can use:

Find the last used cell, before a blank in a Column:

Sub LastCellBeforeBlankInColumn()
Range("A1").End(xldown).Select
End Sub

Find the very last used cell in a Column:

Sub LastCellInColumn()
Range("A" & Rows.Count).End(xlup).Select
End Sub

Find the last cell, before a blank in a Row:

Sub LastCellBeforeBlankInRow()
Range("A1").End(xlToRight).Select
End Sub

Find the very last used cell in a Row:

Sub LastCellInRow()
Range("IV1").End(xlToLeft).Select
End Sub

See here for more information (and the explanation why xlCellTypeLastCell is not very reliable).

List<? extends HasWord> accepts any concrete classes that extends HasWord. If you have the following classes...

public class A extends HasWord { .. }
public class B extends HasWord { .. }
public class C { .. }
public class D extends SomeOtherWord { .. }

... the wordList can ONLY contain a list of either As or Bs or mixture of both because both classes extend the same parent or null (which fails instanceof checks for HasWorld).

Came across this question, and wanted to use some colors on stdout without any dependencies. This combines some of the other great answers here.

Here's what I've got. (Requires node v4 or greater)

// colors.js
const util = require('util')

function colorize (color, text) {
  const codes = util.inspect.colors[color]
  return `\x1b[${codes[0]}m${text}\x1b[${codes[1]}m`
}

function colors () {
  let returnValue = {}
  Object.keys(util.inspect.colors).forEach((color) => {
    returnValue[color] = (text) => colorize(color, text)
  })
  return returnValue
}

module.exports = colors()

Just require the file, then use it like so:

const colors = require('./colors')
console.log(colors.green("I'm green!"))

The predefinied color codes are available here

Something like this:

$(myObj).attr({"data-test-1": num1, "data-test-2": num2});

tl;dr

I know this is old, but getoptlong wasn't mentioned here and it's probably the best way to parse command line arguments today.

Parsing command line arguments

I strongly recommend getoptlong. It's pretty easy to use and works like a charm. Here is an example extracted from the link above

require 'getoptlong'

opts = GetoptLong.new(
    [ '--help', '-h', GetoptLong::NO_ARGUMENT ],
    [ '--repeat', '-n', GetoptLong::REQUIRED_ARGUMENT ],
    [ '--name', GetoptLong::OPTIONAL_ARGUMENT ]
)

dir = nil
name = nil
repetitions = 1
opts.each do |opt, arg|
    case opt
        when '--help'
            puts <<-EOF
hello [OPTION] ... DIR

-h, --help:
     show help

--repeat x, -n x:
     repeat x times

--name [name]:
     greet user by name, if name not supplied default is John

DIR: The directory in which to issue the greeting.
            EOF
        when '--repeat'
            repetitions = arg.to_i
        when '--name'
            if arg == ''
                name = 'John'
            else
                name = arg
            end
    end
end

if ARGV.length != 1
    puts "Missing dir argument (try --help)"
    exit 0
end

dir = ARGV.shift

Dir.chdir(dir)
for i in (1..repetitions)
    print "Hello"
    if name
        print ", #{name}"
    end
    puts
end

You can call it like this ruby hello.rb -n 6 --name -- /tmp

What OP is trying to do

In this case I think the best option is to use YAML files as suggested in this answer

alias -- ddt='ls -trFld'
dt () { ddt --color "$@" | tail -n 30; }

Gives you the most recent files in the current directory. I use it all the time...

Try

python --version 

or

python -V

This will return a current python version in terminal.

Is there any equivalent for the truststore? How can I view the trusted certificates?

Yes there is.The exact same command since keystore and truststore differ only in what they store i.e. private key or signed public key (certificate)

No other difference

Use this command

gcc -dM -E - < /dev/null

to get this

Using the Google Maps API V3, create a Circle object, then use bindTo() to tie it to the position of your Marker (since they are both google.maps.MVCObject instances).

// Create marker 
var marker = new google.maps.Marker({
  map: map,
  position: new google.maps.LatLng(53, -2.5),
  title: 'Some location'
});

// Add circle overlay and bind to marker
var circle = new google.maps.Circle({
  map: map,
  radius: 16093,    // 10 miles in metres
  fillColor: '#AA0000'
});
circle.bindTo('center', marker, 'position');

You can make it look just like the Google Latitude circle by changing the fillColor, strokeColor, strokeWeight etc (full API).

See more source code and example screenshots.

Here is a nice and simple way to do it (but on CENTOS), without braking the operating system.

yum install scl-utils

next

yum install centos-release-scl-rh

And lastly you install the version that you want, lets say python3.5

yum install rh-python35

And lastly:

scl enable rh-python35 bash

Since MAC-OS is a unix operating system, the way to do it it should be quite similar.

Probably it's not be correct, and a little bit longer, but I solved this problem (Android Studio) by using this:

System.out.println("Some text here");

Like this:

try {
       ...code here...
} catch(Exception e) {
  System.out.println("Error desc: " + e.getMessage());
}

Angular Reactive Forms:

onCancel(): void {
  this.registrationForm.reset();
  this.registrationForm.controls['name'].setErrors(null);

Just a minor modification to the excellent answer above by Lessan Vaezi. I ran into a situation where I needed to include attributes in my option entries. The original implementation loses any tag attributes. This version of the above answer preserves the option tag attributes:

jQuery.fn.filterByText = function(textbox) {
  return this.each(function() {
    var select = this;
    var options = [];
    $(select).find('option').each(function() {
      options.push({
          value: $(this).val(),
          text: $(this).text(),
          attrs: this.attributes, // Preserve attributes.
      });
    });
    $(select).data('options', options);

    $(textbox).bind('change keyup', function() {
      var options = $(select).empty().data('options');
      var search = $.trim($(this).val());
      var regex = new RegExp(search, "gi");

      $.each(options, function(i) {
        var option = options[i];
        if (option.text.match(regex) !== null) { 
            var new_option = $('<option>').text(option.text).val(option.value);
            if (option.attrs) // Add old element options to new entry
            {
                $.each(option.attrs, function () {
                    $(new_option).attr(this.name, this.value);
                    });
            }
            
            $(select).append(new_option);
        }
      });
    });
  });
};

How about this?

class name(str):
    def __init__(self, name):
        print (name)
# ------
person1 = name("jean")
person2 = name("dean")
print('===')
print(person1)
print(person2)

Output:

jean
dean
===
jean
dean

public static void set(Map<String, String> newenv) throws Exception {
    Class[] classes = Collections.class.getDeclaredClasses();
    Map<String, String> env = System.getenv();
    for(Class cl : classes) {
        if("java.util.Collections$UnmodifiableMap".equals(cl.getName())) {
            Field field = cl.getDeclaredField("m");
            field.setAccessible(true);
            Object obj = field.get(env);
            Map<String, String> map = (Map<String, String>) obj;
            map.clear();
            map.putAll(newenv);
        }
    }
}

Or to add/update a single var and removing the loop as per thejoshwolfe's suggestion.

@SuppressWarnings({ "unchecked" })
  public static void updateEnv(String name, String val) throws ReflectiveOperationException {
    Map<String, String> env = System.getenv();
    Field field = env.getClass().getDeclaredField("m");
    field.setAccessible(true);
    ((Map<String, String>) field.get(env)).put(name, val);
  }

JAutoDoc:

an Eclipse Plugin for automatically adding Javadoc and file headers to your source code. It optionally generates initial comments from element name by using Velocity templates for Javadoc and file headers...

One thing you can do is get rid of all those onclick attributes and do it the right way with bootstrap. You don't need to open them manually; you can specify the trigger and even subscribe to events before the modal opens so that you can do your operations and populate data in it.

I am just going to show as a static example which you can accommodate in your real world.

On each of your <tr>'s add a data attribute for id (i.e. data-id) with the corresponding id value and specify a data-target, which is a selector you specify, so that when clicked, bootstrap will select that element as modal dialog and show it. And then you need to add another attribute data-toggle=modal to make this a trigger for modal.

  <tr data-toggle="modal" data-id="1" data-target="#orderModal">
            <td>1</td>
            <td>24234234</td>
            <td>A</td>
  </tr>
  <tr data-toggle="modal" data-id="2" data-target="#orderModal">
            <td>2</td>
            <td>24234234</td>
            <td>A</td>
        </tr>
  <tr data-toggle="modal" data-id="3" data-target="#orderModal">
            <td>3</td>
            <td>24234234</td>
            <td>A</td>
  </tr>

And now in the javascript just set up the modal just once and event listen to its events so you can do your work.

$(function(){
    $('#orderModal').modal({
        keyboard: true,
        backdrop: "static",
        show:false,

    }).on('show', function(){ //subscribe to show method
          var getIdFromRow = $(event.target).closest('tr').data('id'); //get the id from tr
        //make your ajax call populate items or what even you need
        $(this).find('#orderDetails').html($('<b> Order Id selected: ' + getIdFromRow  + '</b>'))
    });
});

Demo

Do not use inline click attributes any more. Use event bindings instead with vanilla js or using jquery.

Alternative ways here:

Demo2 or Demo3

You cannot save it as local file without using server side logic. But if that fits your needs, you could look at local storage of html5 or us a javascript plugin as jStorage

As has been suggested at least twice, you can use descendingIterator with a Deque, in particular with a LinkedList. If you want to use the for-each loop (i.e., have an Iterable), you can construct and use a wraper like this:

import java.util.*;

public class Main {

    public static class ReverseIterating<T> implements Iterable<T> {
        private final LinkedList<T> list;

        public ReverseIterating(LinkedList<T> list) {
            this.list = list;
        }

        @Override
        public Iterator<T> iterator() {
            return list.descendingIterator();
        }
    }

    public static void main(String... args) {
        LinkedList<String> list = new LinkedList<String>();
        list.add("A");
        list.add("B");
        list.add("C");
        list.add("D");
        list.add("E");

        for (String s : new ReverseIterating<String>(list)) {
            System.out.println(s);
        }
    }
}

A quick fix to "plot overlap" is to use plt.tight_layout():

Example (in my case)

for i,var in enumerate(categorical_variables):
    plt.title(var)
    plt.xticks(rotation=45)
    df[var].hist()
    plt.subplot(len(categorical_variables)/2, 2, i+1)

plt.tight_layout()

When you cherry-pick, it creates a new commit with a new SHA. If you do:

git cherry-pick -x <sha>

then at least you'll get the commit message from the original commit appended to your new commit, along with the original SHA, which is very useful for tracking cherry-picks.

My first question is which version of SQL Server are you using (i.e 2005, 2008, 2008 R2, 2012)?

Assuming you are using 2008 or later SQL uses scope for variable determination. I believe 2005 still had global variables that would use @@variablename instead of @variable name which would define the difference between global and local variables. Starting in 2008 I believe this was changed to a scope defined variable designation structure. For example to create a global variable the @variable has to be defined at the start of a procedure, function, view, etc. In 2008 and later @@defined system variables for system functions I do believe. I could explain further if you explained the version and also where the variable is being defined, and the error that you are getting.

One user control can't be applied to it ownself. So open another winform and the one will appear in the toolbox.

You'd need to override the negative margins from the .row in large screens either directly or with a custom class

@media (min-width: 768px){
    .row {
        margin-right: 0;
        margin-left: 0;
    }
}

Updated fiddle

To build off what Martjin was saying. I'd use string interpolation/formatting.

In Python 2.x which seems to be what you're using due to the lack of parenthesis around the print function you do:

print 'Value is "%d"' % value

In Python 3.x you'd use the format method instead, so you're code would look like this.

message = 'Value is "{}"'
print(message.format(value))

Class Meta is the place in your code logic where your model.fields MEET With your form.widgets. So under Class Meta() you create the link between your model' fields and the different widgets you want to have in your form.

My first answer in stackoverflow, and I hope it can help someone ^_^

There's lightweight binary editor, check hexedit. http://www.linux.org/apps/AppId_6968.html. I tried using it for editing ELF binaries in Linux at least.

Datetimes are comparable; so you can use max(datetimes_list) and min(datetimes_list)

The easiest way to do this is using ios :: noreplace.

docker ps -a to get container ids then docker exec -it psql -U -W

This will echo standard input to standard output:

import sys
line = sys.stdin.readline()
while line:
    print line,
    line = sys.stdin.readline()

Bottom right hand corner on the status bar, click Spaces: N (or Tab Width: N, where N is an integer), ensure it says Tab Width: 4 for converting from four spaces, and then select Convert Indentation to Tabs from the contextual menu that will appear from the initial click.

Similarly, if you want to do the opposite, click the Spaces or Tab Width text on the status bar and select from the same menu.

I did a little investigation and the solution that works for me was a mix of a few solutions founded in this post.

I'm basically compiling this solution and I'm posting what works for me. In my case, I'm don't want to use any token from .net core.

public async Task ResetPassword(string userId, string password)
{
    var user = await _userManager.FindByIdAsync(userId);
    var hashPassword= _userManager.PasswordHasher.HashPassword(user, password);
    user.PasswordHash = passwordHash;
    await _userManager.UpdateAsync(user);

}

Whenever we are trying to retrieve any data from another server we need two steps.

First step:

-- Server one scalar variable
DECLARE @SERVER VARCHAR(MAX)
--Oracle is the server to which we want to connect
EXEC SP_ADDLINKEDSERVER @SERVER='ORACLE'

Second step:

--DBO is the owner name to know table owner name execute (SP_HELP TABLENAME)    
SELECT * INTO DESTINATION_TABLE_NAME 
FROM ORACLE.SOURCE_DATABASENAME.DBO.SOURCE_TABLE

Try: Controls("Check Box 1") = True

This is nothing to do with hardware nor software. Simply that RGB are the 3 primary colours which can be combined in various ways to produce every other colour. It is more about the human convention/perception of colours which carried over.

Yes, it is called Short-circuit Evaluation.

If the validity of the boolean statement can be assured after part of the statement, the rest is not evaluated.

This is very important when some of the statements have side-effects.

@fthiella 's solution is very elegant.

If in future you want show more than user_id you could use joins, and there in one line could be all data you need.

If you want to use AND conditions, and the conditions are in multiple lines in your table, you can use JOINS example:

SELECT `w_name`.`user_id` 
     FROM `wp_usermeta` as `w_name`
     JOIN `wp_usermeta` as `w_year` ON `w_name`.`user_id`=`w_year`.`user_id` 
          AND `w_name`.`meta_key` = 'first_name' 
          AND `w_year`.`meta_key` = 'yearofpassing' 
     JOIN `wp_usermeta` as `w_city` ON `w_name`.`user_id`=`w_city`.user_id 
          AND `w_city`.`meta_key` = 'u_city'
     JOIN `wp_usermeta` as `w_course` ON `w_name`.`user_id`=`w_course`.`user_id` 
          AND `w_course`.`meta_key` = 'us_course'
     WHERE 
         `w_name`.`meta_value` = '$us_name' AND         
         `w_year`.meta_value   = '$us_yearselect' AND 
         `w_city`.`meta_value` = '$us_reg' AND 
         `w_course`.`meta_value` = '$us_course'

Other thing: Recommend to use prepared statements, because mysql_* functions is not SQL injection save, and will be deprecated. If you want to change your code the less as possible, you can use mysqli_ functions: http://php.net/manual/en/book.mysqli.php

Recommendation:

Use indexes in this table. user_id highly recommend to be and index, and recommend to be the meta_key AND meta_value too, for faster run of query.

The explain:

If you use AND you 'connect' the conditions for one line. So if you want AND condition for multiple lines, first you must create one line from multiple lines, like this.

Tests: Table Data:

          PRIMARY                 INDEX
      int       varchar(255)    varchar(255)
       /                \           |
  +---------+---------------+-----------+
  | user_id | meta_key      | meta_value|
  +---------+---------------+-----------+
  | 1       | first_name    | Kovge     |
  +---------+---------------+-----------+
  | 1       | yearofpassing | 2012      |
  +---------+---------------+-----------+
  | 1       | u_city        | GaPa      |
  +---------+---------------+-----------+
  | 1       | us_course     | PHP       |
  +---------+---------------+-----------+

The result of Query with $us_name='Kovge' $us_yearselect='2012' $us_reg='GaPa', $us_course='PHP':

 +---------+
 | user_id |
 +---------+
 | 1       |
 +---------+

So it should works.

You need to use the reserve function to set an initial allocated size or do it in the initial constructor.

vector<CustomClass *> content(20000);

or

vector<CustomClass *> content;
...
content.reserve(20000);

When you reserve() elements, the vector will allocate enough space for (at least?) that many elements. The elements do not exist in the vector, but the memory is ready to be used. This will then possibly speed up push_back() because the memory is already allocated.

This solves the problem of releasing the memory for me!!!

import gc
import pandas as pd

del [[df_1,df_2]]
gc.collect()
df_1=pd.DataFrame()
df_2=pd.DataFrame()

the data-frame will be explicitly set to null

in the above statements

Firstly, the self reference of the dataframe is deleted meaning the dataframe is no longer available to python there after all the references of the dataframe is collected by garbage collector (gc.collect()) and then explicitly set all the references to empty dataframe.

more on the working of garbage collector is well explained in https://stackify.com/python-garbage-collection/

If you don't feel like changing your MySQL configuration you could use an SQL profiler like "Neor Profile SQL" http://www.profilesql.com .

Since you haven't initialized car yet so it has no existence in JVM(Java Virtual Machine) so you have to initialize it first.

For instance :

car = new String{"Porsche","Lamborghini"};

Now your code will run fine.

INPUT:

String car [];
car = new String{"Porsche","Lamborghini"};
System.out.println(car.length);

OUTPUT:

Modify the following rc parameters by adding the commands to the script:

plt.rcParams['xtick.bottom'] = False
plt.rcParams['xtick.labelbottom'] = False

A sample matplotlibrc file is depicted in this section of the matplotlib documentation, which lists many other parameters like changing figure size, color of figure, animation settings, etc.

No, there's no standard way. I believe that the C/C++ standards don't even consider the existence of directories (or other file system organizations).

On Windows the GetModuleFileName() will return the full path to the executable file of the current process when the hModule parameter is set to NULL. I can't help with Linux.

Also you should clarify whether you want the current directory or the directory that the program image/executable resides. As it stands your question is a little ambiguous on this point.

In Ruby on Rails 3.1.0.rc4:

 request.fullpath

Real answer: No, it's not possible.

OK, I have just thought of a way. Overlay your page with a div that covers the whole document. Inside that, create (say) 2,000 x 2,000 <a> elements (so that the :hover pseudo-class will work in IE 6, see), each 1 pixel in size. Create a CSS :hover rule for those <a> elements that changes a property (let's say font-family). In your load handler, cycle through each of the 4 million <a> elements, checking currentStyle / getComputedStyle() until you find the one with the hover font. Extrapolate back from this element to get the co-ordinates within the document.

N.B. DON'T DO THIS.

Try this!

$("#test *").attr("disabled", "disabled").off('click');

I don't see you using jquery above, but you have it listed as a tag.

If you make

overflow: hidden in the outer div and overflow-y: scroll in the inner div it will work.

Another solution is to Move the aggregate fuction to Scalar User Defined Function

Create Your Function:

CREATE FUNCTION getTotalSalesByProduct(@ProductName VARCHAR(500))
RETURNS INT
AS
BEGIN

DECLARE @TotalAmount INT

SET @TotalAmount = (select SUM(SaleAmount) FROM Sales where Product=@ProductName)

RETURN @TotalAmount

END

Use Function in Where Clause

SELECT ProductName, SUM(SaleAmount) AS TotalSales
FROM Sales
WHERE dbo.getTotalSalesByProduct(ProductName)  > 1000
GROUP BY Product

try

console.log($("#"+d));

your solution is passing the double quotes as part of the string.

Both GET and POST are used by the browser to request a single resource from the server. Each resource requires a separate GET or POST request.

1. The GET method is most commonly (and is the default method) used by browsers to retrieve information from servers. When using the GET method the 3rd section of the request packet, which is the request body, remains empty.

The GET method is used in one of two ways: When no method is specified, that is when you or the browser is requesting a simple resource such as an HTML page, an image, etc. When a form is submitted, and you choose method=GET on the HTML tag. If the GET method is used with an HTML form, then the data collected through the form is sent to the server by appending a "?" to the end of the URL, and then adding all name=value pairs (name of the html form field and value entered in that field) separated by an "&" Example: GET /sultans/shop//form1.jsp?name=Sam%20Sultan&iceCream=vanilla HTTP/1.0 optional headeroptional header<< empty line >>>

The name=value form data will be stored in an environment variable called QUERY_STRING. This variable will be sent to a processing program (such as JSP, Java servlet, PHP etc.)

2. The POST method is used when you create an HTML form, and request method=POST as part of the tag. The POST method allows the client to send form data to the server in the request body section of the request (as discussed earlier). The data is encoded and is formatted similar to the GET method, except that the data is sent to the program through the standard input.

Example: POST /sultans/shop//form1.jsp HTTP/1.0 optional headeroptional header<< empty line >>> name=Sam%20Sultan&iceCream=vanilla

When using the post method, the QUERY_STRING environment variable will be empty. Advantages/Disadvantages of GET vs. POST

Advantages of the GET method: Slightly faster Parameters can be entered via a form or by appending them after the URL Page can be bookmarked with its parameters

Disadvantages of the GET method: Can only send 4K worth of data. (You should not use it when using a textarea field) Parameters are visible at the end of the URL

Advantages of the POST method: Parameters are not visible at the end of the URL. (Use for sensitive data) Can send more that 4K worth of data to server

Disadvantages of the POST method: Can cannot be bookmarked with its data

The second snippet doesn't work either and that's why.

array_shift is a modifier function, that changes its argument. Therefore it expects its parameter to be a reference, and you cannot reference something that is not a variable. See Rasmus' explanations here: Strict standards: Only variables should be passed by reference

The reason for what you faced is that the PDBs ("PDB stands for Program Database, a proprietary file format (developed by Microsoft) for storing debugging information about a program) are not up-to-date, this may be due to some reasons:

1- As Bevan said, you may be debugging another application!

2- You are debugging another version of the same application. For example, you attached a previously built application with the current version of the code for debugging without (re)building it.

Cleaning or Rebuilding the Solution solves such problems for me.

To make sure the problem is not yours, try debugging the same application with VS 2008 (I am afraid it may be a bug in VS 2010 -- it is still beta!).

Just for fun I thought I'd knock it up. It ended up being trickier than I thought because I went in not fully understanding how the boundary part works, eventually I worked out that the starting and ending '--' were significant and off it went.

<?php

        //Set the form flag to no display (cheap way!)
        $flags = 'style="display:none;"';

        //Deal with the email
        $to = '[email protected]';
        $subject = 'a file for you';

        $message = strip_tags($_POST['message']);

Very barebones really, and obviously the using inline CSS to hide the form is a bit cheap and you'd almost certainly want a bit more feedback to the user! Also, I'd probably spend a bit more time working out what the actual Content-Type for the file is, rather than cheating and using application/octet-stream but that part is quite as interesting.

TrustManager[] trustAllCerts = new TrustManager[]{
        new X509TrustManager() {

            public java.security.cert.X509Certificate[] getAcceptedIssuers()
            {
                return null;
            }
            public void checkClientTrusted(java.security.cert.X509Certificate[] certs, String authType)
            {
                //No need to implement.
            }
            public void checkServerTrusted(java.security.cert.X509Certificate[] certs, String authType)
            {
                //No need to implement.
            }
        }
};

// Install the all-trusting trust manager
try 
{
    SSLContext sc = SSLContext.getInstance("SSL");
    sc.init(null, trustAllCerts, new java.security.SecureRandom());
    HttpsURLConnection.setDefaultSSLSocketFactory(sc.getSocketFactory());
} 
catch (Exception e) 
{
    System.out.println(e);
}

Of course this solution should only be used in scenarios, where it is not possible to install the required certifcates using keytool e.g. local testing with temporary certifcates.

When you type integer numbers to JtextField1 after key release it will go to inside try , for any other character it will throw NumberFormatException. If you set empty string to jTextField1 inside the catch so the user cannot type any other keys except positive numbers because JTextField1 will be cleared for each bad attempt.

 //Fields 
int x;
JTextField jTextField1;

 //Gui Code Here

private void jTextField1KeyReleased(java.awt.event.KeyEvent evt) {                                        
    try {
        x = Integer.parseInt(jTextField1.getText());
    } catch (NumberFormatException nfe) {
        jTextField1.setText("");
    }
}   

Use strtotime() and date():

$originalDate = "2010-03-21";
$newDate = date("d-m-Y", strtotime($originalDate));

(See the strtotime and date documentation on the PHP site.)

Note that this was a quick solution to the original question. For more extensive conversions, you should really be using the DateTime class to parse and format :-)

I have successfully run our app, which requires Google Maps API 2, on an AndroVM virtual machine.

AndroVM does not come with Google Maps or Google Play installed, but provides a modified copy of the Cyanogen Gapps archive, which is a set of the proprietary Google apps installed on most Android devices.

The instructions, copied from the AndroVM FAQ:

How can I install Google Apps (including the Market/Play app) ?

• Download Google Apps : gapps-jb-20121011-androvm.tgz [basically the /system directory from the Cyanogen gapps archive without the GoogleTTS app which crashes on AndroVM]
• Untar the gapps…tgz file on your host – you’ll have a system directory created
• Get the management IP address of your AndroVM (“AndroVM Configuration” tool) and do “adb connect x.y.z.t”
• do “adb root”
• reconnect with “adn connect x.y.z.t”
• do “adb remount”
• do “adb push system/ /system/”

Your VM will reboot and you should have google apps including Market/Play.

You won’t have some Google Apps, like Maps, but they can be downloaded from the Market/Play.

So follow those instructions, then just install Google Maps using Google Play!

Some great side effects of using a VM rather than the emulator:

• Vastly superior general performance
• OpenGL acceleration
• Google Play support

The only bump in the road so far has been lack of multi-touch gestures, which is a bummer for a mapping app! I plan to work around this with a hidden UI mechanism, so not such a huge problem.

try this:

string strTime = "04/30/2013 23:00";
DateTime dtTime;
if(DateTime.TryParseExact(strTime, "MM/dd/yyyy HH:mm",  
   System.Globalization.CultureInfo.InvariantCulture, 
   System.Globalization.DateTimeStyles.None, out dtTime))
 {
    Console.WriteLine(dtTime);
 }

Right after our long comment section, I think this is what you're looking for, it's jQuery based:

HTML:

<img width="100%" id="img" src="http://uploads8.wikipaintings.org/images/william-adolphe-bouguereau/self-portrait-presented-to-m-sage-1886.jpg">

JS:

<script type="text/javascript">
window.onload = function(){
       var img = document.getElementById('img')
       if(img.clientHeight<$(window).height()){
            img.style.height=$(window).height()+"px";
       }
       if(img.clientWidth<$(window).width()){
            img.style.width=$(window).width()+"px";
       } 
}
?</script>??????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????

CSS:

body{
    overflow: hidden;
}

?The code above is using the browsers width and height if you where doing this within a div, you would have to change it to something like this:

For Div:

HTML:

<div style="width:100px; max-height: 100px;" id="div">
     <img width="100%" id="img" src="http://uploads8.wikipaintings.org/images/william-adolphe-bouguereau/self-portrait-presented-to-m-sage-1886.jpg">
</div>

JS:

<script type="text/javascript">
window.onload = function(){
       var img = document.getElementById('img')
       if(img.clientHeight<$('#div').height()){
            img.style.height=$('#div').height()+"px";
       }
       if(img.clientWidth<$('#div').width()){
            img.style.width=$('#div').width()+"px";
       } 
}
?</script>????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????

CSS:

div{
   overflow: hidden;
}

I should also state that I've only tested this is Google Chrome... here is a jsfiddle: http://jsfiddle.net/ADCKk/

regular expressions make this easy ...

[A-Z] will match exactly one character between A and Z

\d+ will match one or more digits

() group things (and also return things... but for now just think of them grouping)

+ selects 1 or more

if os.path.exists(filename): os.remove(filename)

is a one-liner.

Many of you may disagree - possibly for reasons like considering the proposed use of ternaries "ugly" - but this begs the question of whether we should listen to people used to ugly standards when they call something non-standard "ugly".

If hardcoding n is an option, you can use sequential calls to sed. For instance, to delete the last three lines, delete the last one line thrice:

sed '$d' file | sed '$d' | sed '$d'

First open the Package Manager Console. Then select your project from the dropdown list. And run the following commands for uninstalling nuget packages.

Get-Package

for getting all the package you have installed.

and then

Uninstall-Package PagedList.Mvc

--- to uninstall a package named PagedList.MVC

Message

PM> Uninstall-Package PagedList.Mvc
Successfully removed 'PagedList.Mvc 4.5.0.0' from MCEMRBPP.PIR.

You can watch props to execute some code upon props changes:

new Vue({_x000D_
  el: '#app',_x000D_
  data: {_x000D_
    text: 'Hello'_x000D_
  },_x000D_
  components: {_x000D_
    'child' : {_x000D_
      template: `<p>{{ myprop }}</p>`,_x000D_
      props: ['myprop'],_x000D_
      watch: { _x000D_
       myprop: function(newVal, oldVal) { // watch it_x000D_
          console.log('Prop changed: ', newVal, ' | was: ', oldVal)_x000D_
        }_x000D_
      }_x000D_
    }_x000D_
  }_x000D_
});

<script src="https://unpkg.com/vue/dist/vue.js"></script>_x000D_
_x000D_
<div id="app">_x000D_
  <child :myprop="text"></child>_x000D_
  <button @click="text = 'Another text'">Change text</button>_x000D_
</div>

You could simply use the unary + operator

(+new Date('2012.08.10')/1000).toFixed(0);

For others needing a key binding:

{ "keys": ["ctrl+="], "command": "upper_case" },
{ "keys": ["ctrl+-"], "command": "lower_case" }

Yes:
