I'm not sure what you're trying to do, but here's something to consider: c(); won't do anything. c is an instance of the class checkbox and not a method to be called. So consider this:

public class FirstWindow extends JFrame {      public FirstWindow() {         checkbox c = new checkbox();         c.yourMethod(yourParameters); // call the method you made in checkbox     } }  public class checkbox extends JFrame {      public checkbox(yourParameters) {          // this is the constructor method used to initialize instance variables     }      public void yourMethod() // doesn't have to be void     {         // put your code here     } } 

Thought this might help to someone, it happens because "When the number of data queries is greater than 1".reference

You can implement startForeground for the service and even if it dies you can restart it by using START_STICKY on startCommand(). Not sure though this is the right implementation.

"Just because you can doesn't mean you should."

You can probably use async/await in LINQ expressions such that it will behave exactly as you want it to, but will any other developer reading your code still understand its behavior and intent?

(In particular: Should the async operations be run in parallel or are they intentionally sequential? Did the original developer even think about it?)

This is also shown clearly by the question, which seems to have been asked by a developer trying to understand someone else's code, without knowing its intent. To make sure this does not happen again, it may be best to rewrite the LINQ expression as a loop statement, if possible.

declare -a arr
echo "-------------------------------------"
echo "Here another example with arr numeric"
echo "-------------------------------------"
arr=( 10 200 3000 40000 500000 60 700 8000 90000 100000 )

echo -e "\n Elements in arr are:\n ${arr[0]} \n ${arr[1]} \n ${arr[2]} \n ${arr[3]} \n ${arr[4]} \n ${arr[5]} \n ${arr[6]} \n ${arr[7]} \n ${arr[8]} \n ${arr[9]}"

echo -e " \n Total elements in arr are : ${arr[*]} \n"

echo -e " \n Total lenght of arr is : ${#arr[@]} \n"

do      echo "The value in position $i for arr is [ ${arr[i]} ]"
done

for (( j=0; j<10; j++ ))

It is not possible to display alerts from the controller. Because MVC views and controllers are entirely separated from each other. You can only display information in the view only. So it is required to pass the information to be displayed from controller to view by using either ViewBag, ViewData or TempData. If you are trying to display the content stored in TempData["Message"], It is possible to perform in the view page by adding few javascript lines.

<script>
  alert(@TempData["Message"]);
</script>

As far as i see it the answer is 'default' is optional, saying a switch must always contain a default is like saying every 'if-elseif' must contain a 'else'. If there is a logic to be done by default, then the 'default' statement should be there, but otherwise the code could continue executing without doing anything.

You should not be using buttons of the same name. It's bad semantics. Instead, you should modify your backend to look for different name values being set:

<input type="submit" name="COMMAND_PREV" value="&lsaquo; Prev">
<input type="submit" name="COMMAND_SAVE" value="Save">
<input type="reset"  name="NOTHING" value="Reset">
<input type="submit" name="COMMAND_NEXT" value="Next &rsaquo;">
<input type="button" name="NOTHING" value="Skip &rsaquo;" onclick="window.location = 'yada-yada.asp';">

Since I don't know what language you are using on the backend, I'll give you some pseudocode:

if (input name COMMAND_PREV is set) {

} else if (input name COMMAND_SAVE is set) {

} else if (input name COMMENT_NEXT is set) {

}

You can pass the element into the function <input type="button" value="mybutton1" onclick="dosomething(this)">test by passing this. Then in the function you can access the value like this:

function dosomething(element) {
  console.log(element.value);
}

Here is another solution using Guava in Java 8 that returns the matched element if one exists in the list. If more than one elements are matched then the collector throws an IllegalArgumentException. A null is returned if there is no match.

Carnet carnet = listCarnet.stream()
                    .filter(c -> c.getCodeIsin().equals(wantedCodeIsin))
                    .collect(MoreCollectors.toOptional())
                    .orElse(null);

This is not a question about make, it is a question about the semantic of the #include directive.

The problem is, that there is no file at the path "../StdCUtil/StdCUtil/split.h". This is the path that results when the compiler combines the include path "../StdCUtil" with the relative path from the #include directive "StdCUtil/split.h".

To fix this, just use -I.. instead of -I../StdCUtil.

The following methods can be used to solve your problem:

1. CSS alpha transparency method (doesn't work in Internet Explorer 8):

   #div{background-color:rgba(255,0,0,0.5);}
   

2. Use a transparent PNG image according to your choice as background.

3. Use the following CSS code snippet to create a cross-browser alpha-transparent background. Here is an example with #000000 @ 0.4% opacity

   .div {
       background:rgb(0,0,0);
       background: transparent\9;
       background:rgba(0,0,0,0.4);
       filter:progid:DXImageTransform.Microsoft.gradient(startColorstr=#66000000,endColorstr=#66000000);
       zoom: 1;
   }
   .div:nth-child(n) {
       filter: none;
   }
   

For more details regarding this technique, see this, which has an online CSS generator.

That's the vi editor. Try ESC :q!.

Replace GetMonthName with GetAbbreviatedMonthName so that it reads:

string strMonthName = mfi.GetAbbreviatedMonthName(8);

I would use the scheduler (control panel) rather than a cmd line or other application.

Control Panel -> Scheduled tasks

if you are using Resharper

fallow the steps in this pic

then write this in template editor

  //#region $name$
$END$$SELECTION$
  //#endregion $name$

and name it #region as in this picture

hope this help you

I had the same problem error that is shown, i solve it by adding

defaultConfig {        
    // Enabling multidex support.
    multiDexEnabled true
}

I had this problem cause i exceeded the 65K methods dex limit imposed by Android i used so many libraries

Log off all users from a machine:

try {
   query user /server:$SERVER 2>&1 | select -skip 1 | foreach {
     logoff ($_ -split "\s+")[-6] /server:$SERVER
   }
}
catch {}

Details:

• the try/catch is used when there are no users are on the server, and the query returns an error. however, you could drop the 2>&1 part, and remove the try/catch if you don't mind seeing the error string
• select -skip 1 removes the header line
• the inner foreach logs off each user
• ($_ -split "\s+") splits the string to an array with just text items
• [-6] index gets session ID and is the 6th string counting from the reverse of the array, you need to do this because the query output will have either 8 or 9 elements depending if the users connected or disconnected from the terminal session

Like Stuart Clark's solution but for Swift 3:

func setTab<T>(_ myClass: T.Type) {
    var i: Int = 0
    if let controllers = self.tabBarController?.viewControllers {
        for controller in controllers {
            if let nav = controller as? UINavigationController, nav.topViewController is T {
                break
            }
            i = i+1
        }
    }
    self.tabBarController?.selectedIndex = i
}

Use it like this:

setTab(MyViewController.self)

Please note that my tabController links to viewControllers behind navigationControllers. Without navigationControllers it would look like this:

if let controller is T {

Here's a way of accomplishing this. It takes the param name and param value, and an optional 'clear'. If you supply clear=true, it will remove all other params and just leave the newly added one - in other cases, it will either replace the original with the new, or add it if it's not present in the querystring.

This is modified from the original top answer as that one broke if it replaced anything but the last value. This will work for any value, and preserve the existing order.

function setGetParameter(paramName, paramValue, clear)
{
clear = typeof clear !== 'undefined' ? clear : false;
var url = window.location.href;
var queryString = location.search.substring(1); 
var newQueryString = "";
if (clear)
{
    newQueryString = paramName + "=" + paramValue;
}
else if (url.indexOf(paramName + "=") >= 0)
{
    var decode = function (s) { return decodeURIComponent(s.replace(/\+/g, " ")); };
    var keyValues = queryString.split('&'); 
    for(var i in keyValues) { 
        var key = keyValues[i].split('=');
        if (key.length > 1) {
            if(newQueryString.length > 0) {newQueryString += "&";}
            if(decode(key[0]) == paramName)
            {
                newQueryString += key[0] + "=" + encodeURIComponent(paramValue);;
            }
            else
            {
                newQueryString += key[0] + "=" + key[1];
            }
        }
    } 
}
else
{
    if (url.indexOf("?") < 0)
        newQueryString = "?" + paramName + "=" + paramValue;
    else
        newQueryString = queryString + "&" + paramName + "=" + paramValue;
}
window.location.href = window.location.href.split('?')[0] + "?" + newQueryString;
}

swift 4

USE ALAMOFIRE in our App plz install pod file

pod 'Alamofire', '~> 4.0'

We can Use API for Json Data -https://swapi.co/api/people/

Then We can create A networking class for Our project- networkingService.swift

import Foundation
import Alamofire
typealias JSON = [String:Any]
class networkingService{
     static let shared = networkingService()
    private init() {}
    func getPeople(success successblock: @escaping (GetPeopleResponse) -> Void)
    {
    Alamofire.request("https://swapi.co/api/people/").responseJSON { response in
        guard let json = response.result.value as? JSON else {return}
       // print(json)
        do {
                let getPeopleResponse = try GetPeopleResponse(json: json)
                successblock(getPeopleResponse)
            }catch{}
    }
    }
    func getHomeWorld(homeWorldLink:String,completion: @escaping(String) ->Void){
        Alamofire.request(homeWorldLink).responseJSON {(response) in
            guard let json = response.result.value as? JSON,
            let name = json["name"] as? String
                else{return}
            completion(name)
        }
}
}

Then Create NetworkingError.swift class

import Foundation
enum networkingError : Error{
    case badNetworkigStuff

}

Then create Person.swift class

import Foundation
struct Person {
    private let homeWorldLink : String
    let birthyear : String
    let gender : String
    let haircolor : String
    let eyecolor : String
    let height : String
    let mass : String
    let name : String
    let skincolor : String
    init?(json : JSON) {
        guard let birthyear = json["birth_year"] as? String,
        let eyecolor = json["eye_color"] as? String,
        let gender = json["gender"] as? String,
        let haircolor = json["hair_color"] as? String,
        let height = json["height"] as? String,
        let homeWorldLink = json["homeworld"] as? String,
        let mass = json["mass"] as? String,
        let name = json["name"] as? String,
        let skincolor = json["skin_color"] as? String
        else { return nil }
        self.homeWorldLink = homeWorldLink
        self.birthyear = birthyear
        self.gender = gender
        self.haircolor = haircolor
        self.eyecolor = eyecolor
        self.height = height
        self.mass = mass
        self.name = name
        self.skincolor = skincolor
    }
    func homeWorld(_ completion: @escaping (String) -> Void)  {
        networkingService.shared.getHomeWorld(homeWorldLink: homeWorldLink){ (homeWorld) in
            completion(homeWorld)
        }
    }
}

Then create DetailVC.swift

import UIKit
class DetailVC: UIViewController {
    var person :Person!
    @IBOutlet var name: UILabel!
    @IBOutlet var birthyear: UILabel!
    @IBOutlet var homeworld: UILabel!
    @IBOutlet var eyeColor: UILabel!
    @IBOutlet var skinColor: UILabel!
    @IBOutlet var gender: UILabel!
    @IBOutlet var hairColor: UILabel!
    @IBOutlet var mass: UILabel!
    @IBOutlet var height: UILabel!
    override func viewDidLoad() {
        super.viewDidLoad()
       print(person)
        name.text = person.name
        birthyear.text = person.birthyear
        eyeColor.text = person.eyecolor
        gender.text = person.gender
        hairColor.text = person.haircolor
        mass.text = person.mass
        height.text = person.height
        skinColor.text = person.skincolor
        person.homeWorld{(homeWorld) in
            self.homeworld.text = homeWorld
        }
    }
}

Then Create GetPeopleResponse.swift class

import Foundation
struct GetPeopleResponse {
    let people : [Person]
    init(json :JSON) throws {
        guard let results = json["results"] as? [JSON] else { throw networkingError.badNetworkigStuff}
        let people = results.map{Person(json: $0)}.flatMap{ $0 }
        self.people = people
        }
}

Then Our View controller class

import UIKit

class ViewController: UIViewController {

    @IBOutlet var tableVieww: UITableView!
    var people = [Person]()


    @IBAction func getAction(_ sender: Any)
    {
    print("GET")
        networkingService.shared.getPeople{ response in
            self.people = response.people
           self.tableVieww.reloadData()
        }
    }
    override func prepare(for segue: UIStoryboardSegue, sender: Any?)
    {
        guard segue.identifier == "peopleToDetails",
        let detailVC = segue.destination as? DetailVC,
        let person = sender as AnyObject as? Person
        else {return}
        detailVC.person = person
        }
}
    extension ViewController:UITableViewDataSource{
        func numberOfSections(in tableView: UITableView) -> Int {
            return 1
        }
        func tableView(_ tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
            return people.count
        }
        func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
         let cell = UITableViewCell()
            cell.textLabel?.text = people[indexPath.row].name

            return cell

        }
    }
extension ViewController:UITableViewDelegate{
    func tableView(_ tableView: UITableView, didSelectRowAt indexPath: IndexPath) {
        performSegue(withIdentifier: "peopleToDetails", sender: people[indexPath.row])
    }
}

In our StoryBoard

plz Connect with our View with another one using segue with identifier -peopleToDetails

• Use UITableView In our First View

• Use UIButton For get the Data

• Use 9 Labels in our DetailVc

This is a safety measure to avoid pushing branches that are not ready to be published. Loosely speaking, by executing "git push", only local branches that already exist on the server with the same name will be pushed, or branches that have been pushed using the localbranch:remotebranch syntax.

To push all local branches to the remote repository, use --all:

git push REMOTENAME --all
git push --all

or specify all branches you want to push:

git push REMOTENAME master exp-branch-a anotherbranch bugfix

In addition, it's useful to add -u to the "git push" command, as this will tell you if your local branch is ahead or behind the remote branch. This is shown when you run "git status" after a git fetch.

I'm doing something like the following code. It works for USB-devices and also the stupid serial8250-devuices that we all have 30 of - but only a couple of them realy works.

Basically I use concept from previous answers. First enumerate all tty-devices in /sys/class/tty/. Devices that does not contain a /device subdir is filtered away. /sys/class/tty/console is such a device. Then the devices actually containing a devices in then accepted as valid serial-port depending on the target of the driver-symlink fx.

$ ls -al /sys/class/tty/ttyUSB0//device/driver
lrwxrwxrwx 1 root root 0 sep  6 21:28 /sys/class/tty/ttyUSB0//device/driver -> ../../../bus/platform/drivers/usbserial

and for ttyS0

$ ls -al /sys/class/tty/ttyS0//device/driver
lrwxrwxrwx 1 root root 0 sep  6 21:28 /sys/class/tty/ttyS0//device/driver -> ../../../bus/platform/drivers/serial8250

All drivers driven by serial8250 must be probes using the previously mentioned ioctl.

        if (ioctl(fd, TIOCGSERIAL, &serinfo)==0) {
            // If device type is no PORT_UNKNOWN we accept the port
            if (serinfo.type != PORT_UNKNOWN)
                the_port_is_valid

Only port reporting a valid device-type is valid.

The complete source for enumerating the serialports looks like this. Additions are welcome.

The actual application/ide/frontend doesn't matter much as long as it goes beyond "notepad, echo and microtime()". It's so unlikely you hire the one in a billion developer that writes perfect code all the time and his/her unit tests spotted all the errors and bottlenecks before they even occur that you want someone who can profile and/or step through the code and find errors in finite time. (That's true for probably all languages/platforms but it seems a bit of an underdeveloped skill-set amongst php developers to me, purely subjective speaking)

While you should definitely avoid circular dependencies, you can defer imports in python.

for example:

import SomeModule

def someFunction(arg):
    from some.dependency import DependentClass

this ( at least in some instances ) will circumvent the error.

Ran into the same issue and found this thread. None of the suggestions above helped except for @Smith's comment to the accepted answer on Apr 17 '13.

The background of my issue is close enough to @zhiyazw's - basically trying to set an exported Excel file (SSRS in my case) as the data source in the dtsx package. All I did, after some tinkering around, was renaming the worksheet. It doesn't have to be lowercase as @Smith has suggested.

I suppose ACE OLEDB expects the Excel file to follow a certain XML structure but somehow Reporting Services is not aware of that.

Function can't change its parameters via the pointer/reference you gave it.

I go to this page every time I need to think about it:

As the az7ar answer is beautifully said but Let me make it simpler with socket.io rooms. request a server with a unique identifier to join a server. here we are using an email as a unique identifier.

Client Socket.io

socket.on('connect', function () {
  socket.emit('join', {email: [email protected]});
});

When the user joined a server, create a room for that user

Server Socket.io

io.on('connection', function (socket) {
   socket.on('join', function (data) {    
    socket.join(data.email);
  });
});

Now we are all set with joining. let emit something to from the server to room, so that user can listen.

Server Socket.io

io.to('[email protected]').emit('message', {msg: 'hello world.'});

Let finalize the topic with listening to message event to the client side

socket.on("message", function(data) {
  alert(data.msg);
});

The reference from Socket.io rooms

• Both 32-bit AND 64-bit processes
• System.Diagnostics only (no System.Management)

I used the solution from Russell Gantman and rewritten it as an extension method you can use like this:

var process = Process.GetProcessesByName("explorer").First();
string path = process.GetMainModuleFileName();
// C:\Windows\explorer.exe

With this implementation:

internal static class Extensions {
    [DllImport("Kernel32.dll")]
    private static extern bool QueryFullProcessImageName([In] IntPtr hProcess, [In] uint dwFlags, [Out] StringBuilder lpExeName, [In, Out] ref uint lpdwSize);

    public static string GetMainModuleFileName(this Process process, int buffer = 1024) {
        var fileNameBuilder = new StringBuilder(buffer);
        uint bufferLength = (uint)fileNameBuilder.Capacity + 1;
        return QueryFullProcessImageName(process.Handle, 0, fileNameBuilder, ref bufferLength) ?
            fileNameBuilder.ToString() :
            null;
    }
}

<?php
$my_array = array('sheldon', 'leonard', 'howard', 'penny');
$to_remove = array('howard');
$result = array_diff($my_array, $to_remove);
?>

When I run your program, it doesn't even get me to the point where I can enter the second date.

This is simpler and less error prone.

import java.io.BufferedReader;
import java.io.InputStreamReader;
import java.text.SimpleDateFormat;
import java.util.Date;

public class Test001 {

    public static void main(String[] args) throws Exception {

        BufferedReader br = null;

        br = new BufferedReader(new InputStreamReader(System.in));
        SimpleDateFormat sdf = new SimpleDateFormat("dd MM yyyy");

        System.out.println("Insert first date : ");
        Date dt1 = sdf.parse(br.readLine().trim());

        System.out.println("Insert second date : ");
        Date dt2 = sdf.parse(br.readLine().trim());

        long diff = dt2.getTime() - dt1.getTime();

        System.out.println("Days: " + diff / 1000L / 60L / 60L / 24L);

        if (br != null) {
            br.close();
        }
    }
}

"From ArrayBuffer to Buffer" could be done this way:

var buffer = Buffer.from( new Uint8Array(ab) );

Inverse of a matrix using python and numpy:

>>> import numpy as np
>>> b = np.array([[2,3],[4,5]])
>>> np.linalg.inv(b)
array([[-2.5,  1.5],
       [ 2. , -1. ]])

Not all matrices can be inverted. For example singular matrices are not Invertable:

>>> import numpy as np
>>> b = np.array([[2,3],[4,6]])
>>> np.linalg.inv(b)

LinAlgError: Singular matrix

Solution to singular matrix problem:

try-catch the Singular Matrix exception and keep going until you find a transform that meets your prior criteria AND is also invertable.

Intuition for why matrix inversion can't always be done; like in singular matrices:

Imagine an old overhead film projector that shines a bright light through film onto a white wall. The pixels in the film are projected to the pixels on the wall.

If I stop the film projection on a single frame, you will see the pixels of the film on the wall and I ask you to regenerate the film based on what you see. That's easy, you say, just take the inverse of the matrix that performed the projection. An Inverse of a matrix is the reversal of the projection.

Now imagine if the projector was corrupted, and I put a distorted lens in front of the film. Now multiple pixels are projected to the same spot on the wall. I asked you again to "undo this operation with the matrix inverse". You say: "I can't because you destroyed information with the lens distortion, I can't get back to where we were, because the matrix is either Singular or Degenerate."

A matrix that can be used to transform some data into other data is invertable only if the process can be reversed with no loss of information. If your matrix can't be inverted, perhaps you are defining your projection using a guess-and-check methodology rather than using a process that guarantees a non-corrupting transform.

If you're using a heuristic or anything less than perfect mathematical precision, then you'll have to define another process to manage and quarantine distortions so that programming by Brownian motion can resume.

you can use show instead of shown for making the function to load just before modal open, instead of after modal open.

$('#code').on('show.bs.modal', function (e) {
  // do something...
})

I am going to assume this is a WinForms questions (which it feels like, based on it being a "program" rather than a website/app). In which case you can simple do the following to change the text colour of a label:

myLabel.ForeColor = System.Drawing.Color.Red;

Or any other colour of your choice. If you want to be more specific you can use an RGB value like so:

myLabel.ForeColor = Color.FromArgb(0, 0, 0);//(R, G, B) (0, 0, 0 = black)

Having different colours for different users can be done a number of ways. For example, you could allow each user to specify their own RGB value colours, store these somewhere and then load them when the user "connects".

An alternative method could be to just use 2 colours - 1 for the current user (running the app) and another colour for everyone else. This would help the user quickly identify their own messages above others.

A third approach could be to generate the colour randomly - however you will likely get conflicting values that do not show well against your background, so I would suggest not taking this approach. You could have a pre-defined list of "acceptable" colours and just pop one from that list for each user that joins.

It is kind of screwy, but in a pinch you can use sed or awk to make small edits or remove text. Be careful with your regex targets of course and be aware that you're likely root on your container and might have to re-adjust permissions.

For example, removing a full line that contains text matching a regex:

awk '!/targetText/' file.txt > temp && mv temp file.txt

Office 365 use two servers, smtp server and protect extended sever.

First server is smtp.office365.com (property Host of smtp client) and second server is STARTTLS/smtp.office365.com (property TargetName of smtp client). Another thing is must put Usedefaultcredential =false before set networkcredentials.

    client.UseDefaultCredentials = False
    client.Credentials = New NetworkCredential("[email protected]", "Password")
    client.Host = "smtp.office365.com"
    client.EnableSsl = true

for me the default search in chrome was locked by smartsputnik.ru. and deleting all the entries in registry and also resetting and reinstalling chrome did not helped . except the below solution.

1. Delete related key from the registry entry- Computer\HKEY_LOCAL_MACCHINE\SOFTWARE\Policies\Google\Chrome
2. Delete file - C:\Windows\System32\GroupPolicy\Machine\registry.pol
3. Restart computer and the problem will be solved

You need to explicitly enable the home action if running on ICS. From the docs:

Note: If you're using the icon to navigate to the home activity, beware that beginning with Android 4.0 (API level 14), you must explicitly enable the icon as an action item by calling setHomeButtonEnabled(true) (in previous versions, the icon was enabled as an action item by default).

To set volume to 0

AudioManager audioManager;
audioManager = (AudioManager) context.getSystemService(Context.AUDIO_SERVICE);
audioManager.setStreamVolume(AudioManager.STREAM_MUSIC, 0, 0);

To set volume to full

AudioManager audioManager;
audioManager = (AudioManager) context.getSystemService(Context.AUDIO_SERVICE);
audioManager.setStreamVolume(AudioManager.STREAM_MUSIC, 20, 0);

the volume can be adjusted by changing the index value between 0 and 20

Navigate to /tomcat-root/conf folder. Within you will find the server.xml file.

Open the server.xml in your preferred editor. Search the below similar statement (not exactly same as below will differ)

    <Connector port="8080" protocol="HTTP/1.1" 
           connectionTimeout="20000" 
           redirectPort="8443" />

Going to give the port number to 9090

     <Connector port="9090" protocol="HTTP/1.1" 
           connectionTimeout="20000" 
           redirectPort="8443" />

Save the file and restart the server. Now the tomcat will listen at port 9090

Don't forget to include

import Image

In order to show it use this :

Image.open('pathToFile').show()

While you can't kill all open connections with a single command, you can create a set of queries to do that for you if there are too many to do by hand.

This example will create a series of KILL <pid>; queries for all some_user's connections from 192.168.1.1 to my_db.

SELECT 
CONCAT('KILL ', id, ';') 
FROM INFORMATION_SCHEMA.PROCESSLIST 
WHERE `User` = 'some_user' 
AND `Host` = '192.168.1.1';
AND `db` = 'my_db';

Oh - the ugliness of Windows... Order of includes are important here. You need to include winsock2.h before windows.h. Since windows.h is probably included from your precompiled header (stdafx.h), you will need to include winsock2.h from there:

#include <winsock2.h>
#include <windows.h>

This is how the regex look like:

import re
# "semicolon or (a comma followed by a space)"
pattern = re.compile(r";|, ")

# "(semicolon or a comma) followed by a space"
pattern = re.compile(r"[;,] ")

print pattern.split(text)

If you don't mind using OFFSET(), which is a volatile function that recalculates everytime a cell is changed, then this is a good solution that is both dynamic and reusable:

=OFFSET($COL:$COL, ROW(), 1, 1048576 - ROW(), 1)

where $COL is the letter of the column you are going to operate upon, and ROW() is the row function that dynamically selects the same row as the cell containing this formula. You could also replace the ROW() function with a static number ($ROW).

=OFFSET($COL:$COL, $ROW, 1, 1048576 - $ROW, 1)

You could further clean up the formula by defining a named constant for the 1048576 as 'maxRows'. This can be done in the 'Define Name' menu of the Formulas tab.

=OFFSET($COL:$COL, $ROW, 1, maxRows - $ROW, 1)

A quick example: to Sum from C6 to the end of column C, you could do:

=SUM(OFFSET(C:C, 6, 1, maxRows - 6, 1))

or =SUM(OFFSET(C:C, ROW(), 1, maxRows - ROW(),1))

The top answer is right, that the error code doesn't give you much info. One of the common causes that we saw in our team for this error code was when the query was not optimized well. A known reason was when we do an inner join with the left side table magnitudes bigger than the table on right side. Swapping these tables would usually do the trick in such cases.

It should usually work using the method Dave described in his answer. (I can confirm seeing "TextFX Characters" in the Available tab in Plugin Manager.)

If it does not, you can try downloading the zip file from here and put its contents (it's one file called NppTextFX.dll) inside the plugins folder where Notepad++ is installed. I suggest doing this while Notepad++ itself is not running.

Well, as Trufa has already shown, there are basically two ways of replacing a tuple's element at a given index. Either convert the tuple to a list, replace the element and convert back, or construct a new tuple by concatenation.

In [1]: def replace_at_index1(tup, ix, val):
   ...:     lst = list(tup)
   ...:     lst[ix] = val
   ...:     return tuple(lst)
   ...:

In [2]: def replace_at_index2(tup, ix, val):
   ...:     return tup[:ix] + (val,) + tup[ix+1:]
   ...:

So, which method is better, that is, faster?

It turns out that for short tuples (on Python 3.3), concatenation is actually faster!

In [3]: d = tuple(range(10))

In [4]: %timeit replace_at_index1(d, 5, 99)
1000000 loops, best of 3: 872 ns per loop

In [5]: %timeit replace_at_index2(d, 5, 99)
1000000 loops, best of 3: 642 ns per loop

Yet if we look at longer tuples, list conversion is the way to go:

In [6]: k = tuple(range(1000))

In [7]: %timeit replace_at_index1(k, 500, 99)
100000 loops, best of 3: 9.08 µs per loop

In [8]: %timeit replace_at_index2(k, 500, 99)
100000 loops, best of 3: 10.1 µs per loop

For very long tuples, list conversion is substantially better!

In [9]: m = tuple(range(1000000))

In [10]: %timeit replace_at_index1(m, 500000, 99)
10 loops, best of 3: 26.6 ms per loop

In [11]: %timeit replace_at_index2(m, 500000, 99)
10 loops, best of 3: 35.9 ms per loop

Also, performance of the concatenation method depends on the index at which we replace the element. For the list method, the index is irrelevant.

In [12]: %timeit replace_at_index1(m, 900000, 99)
10 loops, best of 3: 26.6 ms per loop

In [13]: %timeit replace_at_index2(m, 900000, 99)
10 loops, best of 3: 49.2 ms per loop

So: If your tuple is short, slice and concatenate. If it's long, do the list conversion!

Another layer of indirection:

If you have changed your launch image from a previous image, and observe the following:

• devices/simulators where the app was previously installed, still show the previous image and refuse to show the new one (uninstalling and reinstalling the app doesn't help)
• devices/simulators where the app was not previously installed, show the new launch image

It is likely because of the caching of launch image done by iOS. Rebooting the device should solve the problem.

//Set Preference

Note: Recent npm versions do this automatically when package-locks are enabled, so this is not necessary except for removing development packages with the --production flag.

Run npm prune to remove modules not listed in package.json.

From npm help prune:

This command removes "extraneous" packages. If a package name is provided, then only packages matching one of the supplied names are removed.

Extraneous packages are packages that are not listed on the parent package's dependencies list.

If the --production flag is specified, this command will remove the packages specified in your devDependencies.

The following should do it:

$("input[type='checkbox']").click(function() {
    var index = $(this).attr('name').substr(2);
    $('table tr').each(function() { 
        $('td:eq(' + index + ')',this).toggle();
    });
});

This is untested code, but the principle is that you choose the table cell in each row that corresponds to the chosen index extracted from the checkbox name. You could of course limit the selectors with a class or an ID.

First case: You want to import file A.py in file B.py, these two files are in the same folder, like this:

. 
+-- A.py 
+-- B.py

You can do this in file B.py:

import A

or

from A import *

or

from A import THINGS_YOU_WANT_TO_IMPORT_IN_A

Then you will be able to use all the functions of file A.py in file B.py

Second case: You want to import file folder/A.py in file B.py, these two files are not in the same folder, like this:

.
+-- B.py
+-- folder
     +-- A.py

You can do this in file B:

import folder.A

or

from folder.A import *

or

from folder.A import THINGS_YOU_WANT_TO_IMPORT_IN_A

Then you will be able to use all the functions of file A.py in file B.py

Summary: In the first case, file A.py is a module that you imports in file B.py, you used the syntax import module_name. In the second case, folder is the package that contains the module A.py, you used the syntax import package_name.module_name.

You can make use of ArrayList. Array has the fixed number of size.

This Example here can help you. The example is pretty easy with its output.

Output:
2 5 1 23 14 

New length: 20 

Element at Index 5:29 

List size: 6 

Removing element at index 2: 1

add plt.figure(figsize=(16,5)) before the sns.heatmap and play around with the figsize numbers till you get the desired size

...

plt.figure(figsize = (16,5))

ax = sns.heatmap(df1.iloc[:, 1:6:], annot=True, linewidths=.5)

I hope this example helps. You ca use the curly braces to make sure you've got everything enclosed in the switcher changer guy (sorry don't know the technical term but the term that precedes the = sign that changes what happens). I think of switch as a more controlled bunch of if () {} else {} statements.

Each time the switch function is the same but the command we supply changes.

do.this <- "T1"

switch(do.this,
    T1={X <- t(mtcars)
        colSums(mtcars)%*%X
    },
    T2={X <- colMeans(mtcars)
        outer(X, X)
    },
    stop("Enter something that switches me!")
)
#########################################################
do.this <- "T2"

switch(do.this,
    T1={X <- t(mtcars)
        colSums(mtcars)%*%X
    },
    T2={X <- colMeans(mtcars)
        outer(X, X)
    },
    stop("Enter something that switches me!")
)
########################################################
do.this <- "T3"

switch(do.this,
    T1={X <- t(mtcars)
        colSums(mtcars)%*%X
    },
    T2={X <- colMeans(mtcars)
        outer(X, X)
    },
    stop("Enter something that switches me!")
)

Here it is inside a function:

FUN <- function(df, do.this){
    switch(do.this,
        T1={X <- t(df)
            P <- colSums(df)%*%X
        },
        T2={X <- colMeans(df)
            P <- outer(X, X)
        },
        stop("Enter something that switches me!")
    )
    return(P)
}

FUN(mtcars, "T1")
FUN(mtcars, "T2")
FUN(mtcars, "T3")

I want to update the answer for exception handling in Psr-7 Guzzle, Guzzle7 and HTTPClient(expressive, minimal API around the Guzzle HTTP client provided by laravel).

Guzzle7 (same works for Guzzle 6 as well)

Using RequestException, RequestException catches any exception that can be thrown while transferring requests.

try{
  $client = new \GuzzleHttp\Client(['headers' => ['Authorization' => 'Bearer ' . $token]]);
  
  $guzzleResponse = $client->get('/foobar');
  // or can use
  // $guzzleResponse = $client->request('GET', '/foobar')
    if ($guzzleResponse->getStatusCode() == 200) {
         $response = json_decode($guzzleResponse->getBody(),true);
         //perform your action with $response 
    } 
}
catch(\GuzzleHttp\Exception\RequestException $e){
   // you can catch here 400 response errors and 500 response errors
   // You can either use logs here use Illuminate\Support\Facades\Log;
   $error['error'] = $e->getMessage();
   $error['request'] = $e->getRequest();
   if($e->hasResponse()){
       if ($e->getResponse()->getStatusCode() == '400'){
           $error['response'] = $e->getResponse(); 
       }
   }
   Log::error('Error occurred in get request.', ['error' => $error]);
}catch(Exception $e){
   //other errors 
}

Psr7 Guzzle

use GuzzleHttp\Psr7;
use GuzzleHttp\Exception\RequestException;

try {
    $client->request('GET', '/foo');
} catch (RequestException $e) {
    $error['error'] = $e->getMessage();
    $error['request'] = Psr7\Message::toString($e->getRequest());
    if ($e->hasResponse()) {
        $error['response'] = Psr7\Message::toString($e->getResponse());
    }
    Log::error('Error occurred in get request.', ['error' => $error]);
}

For HTTPClient

use Illuminate\Support\Facades\Http;
try{
    $response = Http::get('http://api.foo.com');
    if($response->successful()){
        $reply = $response->json();
    }
    if($response->failed()){
        if($response->clientError()){
            //catch all 400 exceptions
            Log::debug('client Error occurred in get request.');
            $response->throw();
        }
        if($response->serverError()){
            //catch all 500 exceptions
            Log::debug('server Error occurred in get request.');
            $response->throw();
        }
        
    }
 }catch(Exception $e){
     //catch the exception here
 }

A simple solution to this console.log problem is to define the following at the beginning of your JS code:

if (!window.console) window.console = {};
if (!window.console.log) window.console.log = function () { };

This works for me in all browsers. This creates a dummy function for console.log when the debugger is not active. When the debugger is active, the method console.log is defined and executes normally.

Adding to the above. You use the Dispatch timer if you want the tick events marshalled back to the UI thread. Otherwise I would use System.Timers.Timer.

By default all the EditText widgets in Android are multi-lined.

Here is some sample code:

<EditText
    android:inputType="textMultiLine" <!-- Multiline input -->
    android:lines="8" <!-- Total Lines prior display -->
    android:minLines="6" <!-- Minimum lines -->
    android:gravity="top|left" <!-- Cursor Position -->
    android:maxLines="10" <!-- Maximum Lines -->
    android:layout_height="wrap_content" <!-- Height determined by content -->
    android:layout_width="match_parent" <!-- Fill entire width -->
    android:scrollbars="vertical" <!-- Vertical Scroll Bar -->
/>

You need to remove the part that says data:image/png;base64, at the beginning of the image data. The actual base64 data comes after that.

Just strip everything up to and including base64, (before calling base64_decode() on the data) and you'll be fine.

this might be repetitive. I was trying to use pycharm to run flask - had anaconda 3, pycharm 2019.1.1 and windows 10. Created a new conda environment - it threw errors. Followed these steps -

1. Used the cmd to install python and flask after creating environment as suggested above.

2. Followed this answer.

3. As suggested above, went to Run -> Edit Configurations and changed the environment there as well as in (2).

Obviously kept the correct python interpreter (the one in the environment) everywhere.

Here's the correct answer, extracted from comments by Daniel Rikowski and pseidemann. I'm tired of having to weed through comments to find the right answer...

If you use Rails (ActiveSupport):

result.class.name.demodulize

If you use POR (plain-ol-Ruby):

result.class.name.split('::').last

If you think about it, a body XRay scan (at the medical center) too needs this kind of measurement for estimating size of tumors. So they place a 1 Dollar Coin on the body, to do a comparative measurement.

Even newspaper is printed with some marks on the corners.

You need a reference to measure. May be you can get your person to wear a cap which has a few bright green circles. Once you recognize the size of the circle you can comparatively measure the remaining.

Or you can create a transparent 1 inch circle which will superimpose on the face, move the camera toward/away the face, aim your superimposed circle on that bright green circle on the cap. Then on your photo will be as per scale.

The problem

I had similar problem. Got message in js

Resource interpreted as Document but transferred with MIME type text/csv

But I also got message in chrome console

Mixed Content: The site at 'https://my-site/' was loaded over a secure connection, but the file at 'https://my-site/Download?id=99a50c7b' was redirected through an insecure connection. This file should be served over HTTPS. This download has been blocked

It says here that you need to use an secure connection (but scheme is https in message already, strangely...).

The problem is that href for file downloading builded on server side. And this href used http in my case.

The solution

So I changed scheme to https when build href for file downloading.

Left Click on wamp go to apache> select http.config

change LISTEN:80 to what ever you want you can choose any value of 4 digit like 1311,8000,9999 etc

You should change the generated HTML to not use inline javascript, and use addEventListener instead.

If you can not in any way change the HTML, you could get the onclick attributes, the functions and arguments used, and "convert" it to unobtrusive javascript instead by removing the onclick handlers, and using event listeners.

We'd start by getting the values from the attributes

$('button').each(function(i, el) {_x000D_
    var funcs = [];_x000D_
_x000D_
 $(el).attr('onclick').split(';').map(function(item) {_x000D_
     var fn     = item.split('(').shift(),_x000D_
         params = item.match(/\(([^)]+)\)/), _x000D_
            args;_x000D_
            _x000D_
        if (params && params.length) {_x000D_
         args = params[1].split(',');_x000D_
            if (args && args.length) {_x000D_
                args = args.map(function(par) {_x000D_
              return par.trim().replace(/('")/g,"");_x000D_
             });_x000D_
            }_x000D_
        }_x000D_
        funcs.push([fn, args||[]]);_x000D_
    });_x000D_
  _x000D_
    $(el).data('args', funcs); // store in jQuery's $.data_x000D_
  _x000D_

<button onclick="doAnotherSomething('param1', 'param2')" id="id_button1">action2</button>._x000D_
<button onclick="doDifferentThing()" id="id_button3">action3</button>

That gives us an array of all and any global methods called by the onclick attribute, and the arguments passed, so we can replicate it.

Then we'd just remove all the inline javascript handlers

$('button').removeAttr('onclick')

and attach our own handlers

$('button').on('click', function() {...}

Inside those handlers we'd get the stored original function calls and their arguments, and call them.
As we know any function called by inline javascript are global, we can call them with window[functionName].apply(this-value, argumentsArray), so

$('button').on('click', function() {
    var element = this;
    $.each(($(this).data('args') || []), function(_,fn) {
        if (fn[0] in window) window[fn[0]].apply(element, fn[1]);
    });
});

And inside that click handler we can add anything we want before or after the original functions are called.

$('button').each(function(i, el) {_x000D_
    var funcs = [];_x000D_
_x000D_
 $(el).attr('onclick').split(';').map(function(item) {_x000D_

You should define a key name while storing data to local storage which should be a string and value should be a string

 localStorage.setItem('dataSource', this.dataSource.length);

and to print, you should use getItem

console.log(localStorage.getItem('dataSource'));

I run a small experiment to verify that printing with DBL_DECIMAL_DIG does indeed exactly preserve the number's binary representation. It turned out that for the compilers and C libraries I tried, DBL_DECIMAL_DIG is indeed the number of digits required, and printing with even one digit less creates a significant problem.

#include <float.h>
#include <math.h>
#include <stdio.h>

    int n, num_equal, bin_equal;

    srand(17);
    n = num_equal = bin_equal = 0;
    for (i = 0; i < 1000000; i++) {
        for (j = 0; j < 4; j++)
            u.s[j] = (rand() << 8) ^ rand();
        if (isnan(u.d))
            continue;
        n++;
        sprintf(buff, "%.*g", digits, u.d);
        sscanf(buff, "%lg", &d2);
        if (u.d == d2)
            num_equal++;
        if (memcmp(&u.d, &d2, sizeof(double)) == 0)
            bin_equal++;
    }
    printf("Tested %d values with %d digits: %d found numericaly equal, %d found binary equal\n", n, digits, num_equal, bin_equal);

I run this with Microsoft's C compiler 19.00.24215.1 and gcc version 7.4.0 20170516 (Debian 6.3.0-18+deb9u1). Using one less decimal digit halves the number of numbers that compare exactly equal. (I also verified that rand() as used indeed produces about one million different numbers.) Here are the detailed results.

If you're using SQL Server express, change

SqlConnection conn = new SqlConnection("Server=localhost;" 
       + "Database=Database1;");

to

SqlConnection conn = new SqlConnection("Server=localhost\SQLExpress;" 
       + "Database=Database1;");

That, and hundreds more connection strings can be found at http://www.connectionstrings.com/

One options will be to show the selected option above (or below) the select list like following:

    <option value="1" selected>option 1 The Long Option</option>
    <option value="2">option 2</option>
    <option value="3">option 3</option>
    <option value="4">option 4</option>
    <option value="5">option 5 Another Longer than the Long Option ;)</option>
    <option value="6">option 6</option>
</select>

JavaScript

<script type="text/javascript">
$(document).ready(function(){        
    $("select#mySelect").change(function(){
      //$("#selText").html($($(this).children("option:selected")[0]).text());
       var txt = $($(this).children("option:selected")[0]).text();
       $("<span>" + txt + "<br/></span>").appendTo($("#selText span:last"));
    });
});

If you scale 1600x900 to 1280x720 you have

scale_x = 1280.0/1600
scale_y = 720.0/900

Then you can use it to find button size, and button position

button_width  = 300 * scale_x
button_height = 300 * scale_y

button_x = 1440 * scale_x
button_y = 860  * scale_y

If you scale 1280x720 to 1600x900 you have

scale_x = 1600.0/1280
scale_y = 900.0/720

and rest is the same.

I add .0 to value to make float - otherwise scale_x, scale_y will be rounded to integer - in this example to 0 (zero) (Python 2.x)

This one was perfect for me. Keeps aspect ratio and takes a maxLength. Width or Height will not be more than maxLength

-(UIImage*)imageWithImage: (UIImage*) sourceImage maxLength: (float) maxLength
{
    CGFloat scaleFactor = maxLength / MAX(sourceImage.size.width, sourceImage.size.height);

    float newHeight = sourceImage.size.height * scaleFactor;
    float newWidth = sourceImage.size.width * scaleFactor;

    UIGraphicsBeginImageContext(CGSizeMake(newWidth, newHeight));
    [sourceImage drawInRect:CGRectMake(0, 0, newWidth, newHeight)];
    UIImage *newImage = UIGraphicsGetImageFromCurrentImageContext();
    UIGraphicsEndImageContext();
    return newImage;
}

As described in the various XML specifications, an element is that which consists of a start tag, and end tag, and the content in between, or alternately an empty element tag (which has no content or end tag). In other words, these are all elements:

<foo> stuff </foo>
<foo bar="baz"></foo>
<foo baz="qux" />

Though you hear "node" used with roughly the same meaning, it has no precise definition per XML specs. It's usually used to refer to nodes of things like DOMs, which may be closely related to XML or use XML for their representation.

The R class is Java code auto-generated from your XML files (UI layout, internationalization strings, etc.) If the code used to be working before (as it seems it is), you need to tell your IDE to regenerate these files somehow:

• in IntelliJ, select Tools > Android > Generate sources for <project>
• (If you know the way in another IDE, feel free to edit this answer!)

For child-parent communication you should pass a function setting the state from parent to child, like this

class Parent extends React.Component {_x000D_
  constructor(props) {_x000D_
    super(props)_x000D_
_x000D_
    this.handler = this.handler.bind(this)_x000D_
  }_x000D_
_x000D_
  handler() {_x000D_
    this.setState({_x000D_
      someVar: 'some value'_x000D_
    })_x000D_
  }_x000D_
_x000D_
  render() {_x000D_
    return <Child handler = {this.handler} />_x000D_
  }_x000D_
}_x000D_
_x000D_
class Child extends React.Component {_x000D_
  render() {_x000D_
    return <Button onClick = {this.props.handler}/ >_x000D_
  }_x000D_
}

This way the child can update the parent's state with the call of a function passed with props.

But you will have to rethink your components' structure, because as I understand components 5 and 3 are not related.

One possible solution is to wrap them in a higher level component which will contain the state of both component 1 and 3. This component will set the lower level state through props.

For me, I installed it on a Mac via Homebrew and it is not set up as a service. To run the memcached server, I simply execute memcached -d. This will establish Memcached server on the default port, 11211.

Try replacing the appropriate lines with:

myStringArray[0][x-1] = "a string";
myStringArray[0][y-1] = "another string";

Your code is incorrect because the sub-arrays have a length of y, and indexing starts at 0. So setting to myStringArray[0][y] or myStringArray[0][x] will fail because the indices x and y are out of bounds.

String[][] myStringArray = new String [x][y]; is the correct way to initialise a rectangular multidimensional array. If you want it to be jagged (each sub-array potentially has a different length) then you can use code similar to this answer. Note however that John's assertion that you have to create the sub-arrays manually is incorrect in the case where you want a perfectly rectangular multidimensional array.

A simple example for writing multiple data to excel at a time. And also when you want to append data to a sheet on a written excel file (closed excel file).

When it is your first time writing to an excel. (Writing "df1" and "df2" to "1st_sheet" and "2nd_sheet")

import pandas as pd 
from openpyxl import load_workbook

df1 = pd.DataFrame([[1],[1]], columns=['a'])
df2 = pd.DataFrame([[2],[2]], columns=['b'])
df3 = pd.DataFrame([[3],[3]], columns=['c'])

excel_dir = "my/excel/dir"

with pd.ExcelWriter(excel_dir, engine='xlsxwriter') as writer:    
    df1.to_excel(writer, '1st_sheet')   
    df2.to_excel(writer, '2nd_sheet')   
    writer.save()    

After you close your excel, but you wish to "append" data on the same excel file but another sheet, let's say "df3" to sheet name "3rd_sheet".

book = load_workbook(excel_dir)
with pd.ExcelWriter(excel_dir, engine='openpyxl') as writer:
    writer.book = book
    writer.sheets = dict((ws.title, ws) for ws in book.worksheets)    

    ## Your dataframe to append. 
    df3.to_excel(writer, '3rd_sheet')  

    writer.save()     

Be noted that excel format must not be xls, you may use xlsx one.

A jar file is a zip file with some additional files containing metadata. (Despite the .jar extension, it is in zip format, and any utilities that deal with .zip files are also able to deal with .jar files.)

http://docs.oracle.com/javase/8/docs/technotes/guides/jar/index.html

Jar files can contain any kind of files, but they usually contain class files and supporting configuration files (properties), graphics and other data files needed by the application.

Class files contain compiled Java code, which is executable by the Java Virtual Machine.

http://en.wikipedia.org/wiki/Java_class_file

<div class="row">
  <div class="col-md-6">
     <img src="/assets/images/ebook2.png" alt="" class="img-fluid">
  </div>
  <div class="col-md-6 my-auto">
     <h3>Heading</h3>
     <p>Some text.</p>
   </div>
</div>

This line is where the magic happens <div class="col-md-6 my-auto">, the my-auto will center the content of the column. This works great with situations like the code sample above where you might have a variable sized image and need to have the text in the column to the right line up with it.

Use a dictionary!!

You can also use dictionaries that allows you to have more control over the plots:

import matplotlib.pyplot as plt
#   plot 0     plot 1    plot 2   plot 3
x=[[1,2,3,4],[1,4,3,4],[1,2,3,4],[9,8,7,4]]
y=[[3,2,3,4],[3,6,3,4],[6,7,8,9],[3,2,2,4]]

plots = zip(x,y)
def loop_plot(plots):
    figs={}
    axs={}
    for idx,plot in enumerate(plots):
        figs[idx]=plt.figure()
        axs[idx]=figs[idx].add_subplot(111)
        axs[idx].plot(plot[0],plot[1])
return figs, axs

figs, axs = loop_plot(plots)

Now you can select the plot that you want to modify easily:

axs[0].set_title("Now I can control it!")

Of course, is up to you to decide what to do with the plots. You can either save them to disk figs[idx].savefig("plot_%s.png" %idx) or show them plt.show(). Use the argument block=False only if you want to pop up all the plots together (this could be quite messy if you have a lot of plots). You can do this inside the loop_plot function or in a separate loop using the dictionaries that the function provided.

$(selectedDOM).find();

function looking for all dom objects inside the selected DOM. i.e.

<div id="mainDiv">
    <p>Paragraph 1</p>
    <p>Paragraph 2</p>
    <div id="innerDiv">
         <a href="#">link</a>
         <p>Paragraph 3</p>
    </div>
</div>

here if you write;

$("#mainDiv").find("p");

you will get tree p elements together. On the other side,

$("#mainDiv").children("p");

Function searching in the just children DOMs of the selected DOM object. So, by this code you will get just paragraph 1 and paragraph 2. It is so beneficial to prevent browser doing unnecessary progress.

To answer your question as I understand it: Why use C#? (You say you're already sold on F#.)

First off. It's not just "functional versus OO". It's "Functional+OO versus OO". C#'s functional features are pretty rudimentary. F#'s are not. Meanwhile, F# does almost all of C#'s OO features. For the most part, F# ends up as a superset of C#'s functionality.

However, there are a few cases where F# might not be the best choice:

• Interop. There are plenty of libraries that just aren't going to be too comfortable from F#. Maybe they exploit certain C# OO things that F# doesn't do the same, or perhaps they rely on internals of the C# compiler. For example, Expression. While you can easily turn an F# quotation into an Expression, the result is not always exactly what C# would create. Certain libraries have a problem with this.

  • Yes, interop is a pretty big net and can result in a bit of friction with some libraries.

  • I consider interop to also include if you have a large existing codebase. It might not make sense to just start writing parts in F#.

• Design tools. F# doesn't have any. Does not mean it couldn't have any, but just right now you can't whip up a WinForms app with F# codebehind. Even where it is supported, like in ASPX pages, you don't currently get IntelliSense. So, you need to carefully consider where your boundaries will be for generated code. On a really tiny project that almost exclusively uses the various designers, it might not be worth it to use F# for the "glue" or logic. On larger projects, this might become less of an issue.

  • This isn't an intrinsic problem. Unlike the Rex M's answer, I don't see anything intrinsic about C# or F# that make them better to do a UI with lots of mutable fields. Maybe he was referring to the extra overhead of having to write "mutable" and using <- instead of =.

  • Also depends on the library/designer used. We love using ASP.NET MVC with F# for all the controllers, then a C# web project to get the ASPX designers. We mix the actual ASPX "code inline" between C# and F#, depending on what we need on that page. (IntelliSense versus F# types.)

• Other tools. They might just be expecting C# only and not know how to deal with F# projects or compiled code. Also, F#'s libraries don't ship as part of .NET, so you have a bit extra to ship around.

• But the number one issue? People. If none of your developers want to learn F#, or worse, have severe difficulty comprehending certain aspects, then you're probably toast. (Although, I'd argue you're toast anyways in that case.) Oh, and if management says no, that might be an issue.

I wrote about this a while ago: Why NOT F#?

I needed to also deal with + in the query part of the URL (decodeURIComponent doesn't), so I adapted Wolfgang's code to become:

var search = location.search.substring(1);
search = search?JSON.parse('{"' + search.replace(/\+/g, ' ').replace(/&/g, '","').replace(/=/g,'":"') + '"}',
             function(key, value) { return key===""?value:decodeURIComponent(value)}):{};

In my case, I'm using jQuery to get URL-ready form parameters, then this trick to build an object out of it and I can then easily update parameters on the object and rebuild the query URL, e.g.:

var objForm = JSON.parse('{"' + $myForm.serialize().replace(/\+/g, ' ').replace(/&/g, '","').replace(/=/g,'":"') + '"}',
             function(key, value) { return key===""?value:decodeURIComponent(value)});
objForm.anyParam += stringToAddToTheParam;
var serializedForm = $.param(objForm);

ES2015 UPDATE

ES2015 have String#includes method that checks whether a string contains another. This can be used if the target environment supports it. The method returns true if the needle is found in haystack else returns false.

ng-if="haystack.includes(needle)"

Here, needle is the string that is to be searched in haystack.

See Browser Compatibility table from MDN. Note that this is not supported by IE and Opera. In this case polyfill can be used.

You can use String#indexOf to get the index of the needle in haystack.

1. If the needle is not present in the haystack -1 is returned.
2. If needle is present at the beginning of the haystack 0 is returned.
3. Else the index at which needle is, is returned.

The index can be compared with -1 to check whether needle is found in haystack.

ng-if="haystack.indexOf(needle) > -1" 

For Angular(2+)

*ngIf="haystack.includes(needle)"

You can add it to your shell configuration file, e.g. $HOME/.bashrc or more globally in /etc/environment. After adding these lines the changes won't reflect instantly in GUI based system's you have to exit the terminal or create a new one and in server logout the session and login to reflect these changes.

The short answer:

Use the click event, which won't fire until after the value has been updated, and fires when you want it to:

<label><input type='checkbox' onclick='handleClick(this);'>Checkbox</label>

function handleClick(cb) {
  display("Clicked, new value = " + cb.checked);
}

Live example | Source

The longer answer:

The change event handler isn't called until the checked state has been updated (live example | source), but because (as Tim Büthe points out in the comments) IE doesn't fire the change event until the checkbox loses focus, you don't get the notification proactively. Worse, with IE if you click a label for the checkbox (rather than the checkbox itself) to update it, you can get the impression that you're getting the old value (try it with IE here by clicking the label: live example | source). This is because if the checkbox has focus, clicking the label takes the focus away from it, firing the change event with the old value, and then the click happens setting the new value and setting focus back on the checkbox. Very confusing.

But you can avoid all of that unpleasantness if you use click instead.

I've used DOM0 handlers (onxyz attributes) because that's what you asked about, but for the record, I would generally recommend hooking up handlers in code (DOM2's addEventListener, or attachEvent in older versions of IE) rather than using onxyz attributes. That lets you attach multiple handlers to the same element and lets you avoid making all of your handlers global functions.

An earlier version of this answer used this code for handleClick:

function handleClick(cb) {
  setTimeout(function() {
    display("Clicked, new value = " + cb.checked);
  }, 0);
}

The goal seemed to be to allow the click to complete before looking at the value. As far as I'm aware, there's no reason to do that, and I have no idea why I did. The value is changed before the click handler is called. In fact, the spec is quite clear about that. The version without setTimeout works perfectly well in every browser I've tried (even IE6). I can only assume I was thinking about some other platform where the change isn't done until after the event. In any case, no reason to do that with HTML checkboxes.

I would change your binding to be:

<button type="button" value="click me" onclick="check_me" />

I would then change your check_me() function declaration to be:

function check_me() {   
  //event.preventDefault();
  var hello = document.myForm.username.value;
  var err = '';

  if(hello == '' || hello == null) {
    err = 'User name required';
  }

  if(err != '') { 
     alert(err); 
     $('username').focus(); 
     event.preventDefault(); 
   } else { 
    return true; }
}

What are the advantages of having a contiguous block of memory? Specifically, why would I need to have a contiguous physical block of memory in a system call? Is there any reason I couldn't just use vmalloc?

From Google's "I'm Feeling Lucky" on vmalloc:

kmalloc is the preferred way, as long as you don't need very big areas. The trouble is, if you want to do DMA from/to some hardware device, you'll need to use kmalloc, and you'll probably need bigger chunk. The solution is to allocate memory as soon as possible, before memory gets fragmented.

NOT IN vs. NOT EXISTS vs. LEFT JOIN / IS NULL in MySQL

MySQL, as well as all other systems except SQL Server, is able to optimize LEFT JOIN / IS NULL to return FALSE as soon the matching value is found, and it is the only system that cared to document this behavior. […] Since MySQL is not capable of using HASH and MERGE join algorithms, the only ANTI JOIN it is capable of is the NESTED LOOPS ANTI JOIN

[…]

Essentially, [NOT IN] is exactly the same plan that LEFT JOIN / IS NULL uses, despite the fact these plans are executed by the different branches of code and they look different in the results of EXPLAIN. The algorithms are in fact the same in fact and the queries complete in same time.

It’s hard to tell exact reason for [performance drop when using NOT EXISTS], since this drop is linear and does not seem to depend on data distribution, number of values in both tables etc., as long as both fields are indexed. Since there are three pieces of code in MySQL that essentialy do one job, it is possible that the code responsible for EXISTS makes some kind of an extra check which takes extra time.

[…]

MySQL can optimize all three methods to do a sort of NESTED LOOPS ANTI JOIN. […] However, these three methods generate three different plans which are executed by three different pieces of code. The code that executes EXISTS predicate is about 30% less efficient […]

That’s why the best way to search for missing values in MySQL is using a LEFT JOIN / IS NULL or NOT IN rather than NOT EXISTS.

(emphases added)

C# supports two boolean or operators: the single bar | and the double-bar ||.

The difference is that | always checks both the left and right conditions, while || only checks the right-side condition if it's necessary (if the left side evaluates to false).

This is significant when the condition on the right-side involves processing or results in side effects. (For example, if your ErrorDumpWriter.Close method took a while to complete or changed something's state.)

my two cents about logic:

syntax is "old date" - :"new date", so:

SELECT TIMESTAMPDIFF(SECOND, '2018-11-15 15:00:00', '2018-11-15 15:00:30')

gives 30,

SELECT TIMESTAMPDIFF(SECOND, '2018-11-15 15:00:55', '2018-11-15 15:00:15')

gives: -40

Our Server environment : SQL2008 x64 SP2 Reporting Services on Windows Server 2008 x64,

Client PC environment: Windows XP SP2 with IE6 or higher, all users are login to Active Directory, users are not members of local Administrator or power user group.

Error: When a user printing a report getting an error as "Unable to load client print control"

Solution that work for us: replace following files in sql 2008 with SQL 2008 R2

Program Files\Microsoft SQL Server\MSRS10.MSSQLSERVER\Reporting Services\ReportServer\bin RSClientPrint-x86.cab RSClientPrint-x64.cab RSClientPrint-ia64.cab

Once you replace the files one server users wont get above error and they do not required local power user or admin right to download Active X. Recommending to add report server URL as a trusted site (add to Trusted sites) via Active Directory GP.

SELECT LAST(row_name) FROM table_name

In my case I use finishAffinity() function in last activity like:

finishAffinity()
startHomeActivity()

Hope it'll be useful.

This error would happen when the number of guesses (so_far) is less than the length of the word. Did you miss an initialization for the variable so_far somewhere, that sets it to something like

so_far = " " * len(word)

?

Edit:

try something like

print "%d / %d" % (new, so_far)

before the line that throws the error, so you can see exactly what goes wrong. The only thing I can think of is that so_far is in a different scope, and you're not actually using the instance you think.

Just had the same issue on Windows Server 2008 R2 and nothing helped, not taskmanager or taskkill. But, windows powershell run as administrator worked with "kill -id pid"

I had the same issue and I resolved it by making changes in the UnityConfig.cs file In order to resolve the dependency issue in the UnityConfig.cs file you have to add:

public static void RegisterComponents()    
{
    var container = new UnityContainer();
    container.RegisterType<ITestService, TestService>();
    DependencyResolver.SetResolver(new UnityDependencyResolver(container));
}

If there are true answers to those questions, it would be different per software vendor and would be defined by the vendor. I don't know of any true industry standards that are followed with regards to this matter.

Historically with Microsoft, they'll mark something as deprecated and state they'll remove it in a future version. That can be several versions before they actually get rid of it though.

I was able to fix it using the answer here: https://stackoverflow.com/a/32176571/1174024 But I have 150 modules. So I would have had to perform this step 150 times.

So I needed to do it a different way.

So first close the existing project, then Import it again, In the first step of the wizard choose "Gradle" project. Then the next step of the wizard has the Gradle project properties. Here it's going to ask you for, among other things, the Java SDK to use. The default will be "Project SDK". Do not use this default, instead hand pick your Java SDK from the list. Then finish the import.

Now the problem should go away.

You could try my Beavertail ADSI browser - it should show you the current AD tree, and from it, you should be able to figure out the path and all.

Or if you're on .NET 3.5, using the System.DirectoryServices.AccountManagement namespace, you could also do it programmatically:

PrincipalContext ctx = new PrincipalContext(ContextType.Domain);

This would create a basic, default domain context and you should be able to peek at its properties and find a lot of stuff from it.

Or:

UserPrincipal myself = UserPrincipal.Current;

This will give you a UserPrincipal object for yourself, again, with a ton of properties to inspect. I'm not 100% sure what you're looking for - but you most likely will be able to find it on the context or the user principal somewhere!

As of May 2015 Chrome beta/dev/canary on Windows (see lines 75-78) always display this warning.

• I've just patched chrome.dll (dev channel, 32-bit) using hiew32 demo version: run it, switch to hex view (Enter key), search for ExtensionDeveloperModeWarning (F7) then press F6 to find the referring code, go to nearby INC EAX line, which is followed by RETN, press F3 to edit, type 90 instead of 40, which will be rendered as NOP (no-op), save (F9).

• Simplified method found by @Gsx, which also works for 64-bit Chrome dev:

  1. run hiew32 demo (in admin mode) and open Chrome.dll
  2. switch to hex view (Enter key)
  3. search for ExtensionDeveloperModeWarning (F7)
  4. press F3 to edit and replace the first letter "E" with any other character
  5. save (F9).

• patch.BAT script

Of course this will last only until the next update so whoever needs it frequently might write an auto-patcher or a launcher that patches the dll in memory.

Simply pass the desired value as first argument, like 0, math.inf or, here, np.nan. The constructor then initializes and fills the value array to the size specified by arguments index and columns:

>>> import numpy as np
>>> import pandas as pd
>>> df = pd.DataFrame(np.nan, index=[0, 1, 2, 3], columns=['A', 'B'])

>>> df.dtypes
A    float64
B    float64
dtype: object

>>> df.values
array([[nan, nan],
       [nan, nan],
       [nan, nan],
       [nan, nan]])

Before applying

You can still do this in top. While top is running, press '1' on your keyboard, it will then show CPU usage per core.

Limit the processes shown by having that specific process run under a specific user account and use Type 'u' to limit to that user

I am using something like this - codeigniter-htaccess-file, its a good article to begin with.

• leave the .htaccess file in CI root dir
• make sure that mod_rewrite is on
• check for typos (ie. controller file/class name)
• in /application/config/config.php set $config['index_page'] = "";
• in /application/config/routes.php set your default controller $route['default_controller']="home";

If you are running clean installation of CI (2.1.3) there isn't really much that could be wrong.

• 2 config files
• controller
• .htaccess
• mod_rewrite

• Codeigniter .htaccess
• redirect-index-php-in-codeigniter

Edit the httpd.conf file and replace the line DocumentRoot "/home/user/www" to your liked one.

The default DocumentRoot path will be different for windows [the above is for linux].

The object, method, and property names in the .NET language bindings do not exactly correspond to those in the Java bindings. One of the principles of the project is that each language binding should "feel natural" to those comfortable coding in that language. In C#, the code you'd want for executing JavaScript is as follows

IWebDriver driver; // assume assigned elsewhere
IJavaScriptExecutor js = (IJavaScriptExecutor)driver;
string title = (string)js.ExecuteScript("return document.title");

Note that the complete documentation of the WebDriver API for .NET can be found at this link.

select FOUND_ROWS();

will return no. of records selected by select query.

Simplified prior suggestions and providing code for .NET Web Forms developers.

This will accept both relative ("~/") and absolute urls in the file path to the resource.

Put in a static extensions class file, the following:

public static string VersionedContent(this HttpContext httpContext, string virtualFilePath)
{
    var physicalFilePath = httpContext.Server.MapPath(virtualFilePath);
    if (httpContext.Cache[physicalFilePath] == null)
    {
        httpContext.Cache[physicalFilePath] = ((Page)httpContext.CurrentHandler).ResolveUrl(virtualFilePath) + (virtualFilePath.Contains("?") ? "&" : "?") + "v=" + File.GetLastWriteTime(physicalFilePath).ToString("yyyyMMddHHmmss");
    }
    return (string)httpContext.Cache[physicalFilePath];
}

And then call it in your Master Page as such:

<link type="text/css" rel="stylesheet" href="<%= Context.VersionedContent("~/styles/mystyle.css") %>" />
<script type="text/javascript" src="<%= Context.VersionedContent("~/scripts/myjavascript.js") %>"></script>

Generic functional form

def select_columns(data_frame, column_names):
    new_frame = data_frame.loc[:, column_names]
    return new_frame

Specific for your problem above

selected_columns = ['A', 'C', 'D']
new = select_columns(old, selected_columns)

First of all go to the device manager now go to View>>select Show hidden devices....Then go to network adapters and find out Microsoft Hosted network Virual Adapter ....Press right click and enable the option....

Then go to command prompt with administrative privileges and enter the following commands:

netsh wlan set hostednetwork mode=allow
netsh wlan start hostednetwork

Your Hostednetwork will work without any problems.

In place of 1.+ use the latest version of crashlytics -

 dependencies {
        classpath 'com.crashlytics.tools.gradle:crashlytics-gradle:1.+'
    }

you should use this way -

dependencies {
            classpath 'com.crashlytics.tools.gradle:crashlytics-gradle:2.6.8'
        }

your problem will be resolved for sure. Happy coding !!

I know this is an old question, but rather than adding the snapin which is apparently unsupported, I just looked at the EMS shortcut properties and copied those commands.

The full shortcut target is:

C:\Windows\System32\WindowsPowerShell\v1.0\powershell.exe -noexit -command ". 'C:\Program Files\Microsoft\Exchange Server\V14\bin\RemoteExchange.ps1'; Connect-ExchangeServer -auto"

So I put the following at the start of my script and it seemed to function as expected:

. 'C:\Program Files\Microsoft\Exchange Server\V14\bin\RemoteExchange.ps1'
Connect-ExchangeServer -auto

Notes:

• Has to be run in 64bit PS
• This was tested on a server with just the Management Tools installed. It automatically connected to our existing Exchange infrastructure.
• No extensive testing has been done, so I do not know if this method is viable. I will edit this post if I run into any issues.

You can just add an onClick handler to the div with the function (onClick is React's own implementation of onClick) and you can access the property within { } curly braces, and your alert message will appear.

In case you wish to define static methods that can be called on the component class - you should use statics. Although:

"Methods defined within this block are static, meaning that you can run them before any component instances are created, and the methods do not have access to the props or state of your components. If you want to check the value of props in a static method, have the caller pass in the props as an argument to the static method." (source)

Some example code:

    const Hello = React.createClass({

        /*
            The statics object allows you to define static methods that can be called on the component class. For example:
        */
        statics: {
            customMethod: function(foo) {
              return foo === 'bar';
            }
        },


        alertMessage: function() {
            alert(this.props.name);                             
        },

        render: function () {
            return (
                <div onClick={this.alertMessage}>
                Hello {this.props.name}
                </div>
            );
        }
    });

    React.render(<Hello name={'aworld'} />, document.body);

Hope this helps you a bit, because i don't know if I understood your question correctly, so correct me if i interpreted it wrong:)

If you know the number of elements per "row" and the width of the container you can use a selector to add a margin to the elements you need to cause a justified look.

I had rows of three divs I wanted justified so used the:

.tile:nth-child(3n+2) { margin: 0 10px }

this allows the center div in each row to have a margin that forces the 1st and 3rd div to the outside edges of the container

Also great for other things like borders background colors etc

I had the same problem with a Google Docs URL. Enclosing the URL in quotes did the trick for me:

I think, when I read your story that [3] is also on the backstack. This explains why you see it flashing up.

Solution would be to never set [3] on the stack.

To select (or remove) object properties that satisfy a given condition deeply, you can use something like this:

function pickByDeep(object, condition, arraysToo=false) {
  return _.transform(object, (acc, val, key) => {
    if (_.isPlainObject(val) || arraysToo && _.isArray(val)) {
      acc[key] = pickByDeep(val, condition, arraysToo);
    } else if (condition(val, key, object)) {
      acc[key] = val;
    }
  });
}

I needed to use raw sql because I failed at getting composite_primary_keys to function with activerecord 2.3.8. So in order to access the sqlserver 2000 table with a composite primary key, raw sql was required.

sql = "update [db].[dbo].[#{Contacts.table_name}] " +
      "set [COLUMN] = 0 " +
      "where [CLIENT_ID] = '#{contact.CLIENT_ID}' and CONTACT_ID = '#{contact.CONTACT_ID}'"
st = ActiveRecord::Base.connection.raw_connection.prepare(sql)
st.execute

For those on mac looking for keytool. follow these steps:

Firstly make sure to install Java JDK http://docs.oracle.com/javase/7/docs/webnotes/install/mac/mac-jdk.html

Then type this into command prompt:

/usr/libexec/java_home -v 1.7

it will spit out something like:

/Library/Java/JavaVirtualMachines/jdk1.7.0_51.jdk/Contents/Home

keytool is located in the same directory as javac. ie:

/Library/Java/JavaVirtualMachines/jdk1.7.0_51.jdk/Contents/Home/bin

From bin directory you can use the keytool.

Case 1:Only two activity A and B:

Here Activity flow is A->B .On clicking backbutton from B we need to close the application then while starting Activity B from A just call finish() this will prevent android from storing Activity A in to the Backstack.eg for activity A is Loding/Splash screen of application.

Intent newIntent = new Intent(A.this, B.class);
startActivity(newIntent);
finish();

Case 2:More than two activitiy:

If there is a flow like A->B->C->D->B and on clicking back button in Activity B while coming from Activity D.In that case we should use.

Intent newIntent = new Intent(D.this,B.class);
newIntent.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP); 
newIntent.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
startActivity(newIntent);

Here Activity B will be started from the backstack rather than a new instance because of Intent.FLAG_ACTIVITY_CLEAR_TOP and Intent.FLAG_ACTIVITY_NEW_TASK clears the stack and makes it the top one.So when we press back button the whole application will be terminated.

I used this and it works well:

string[] filePaths = Directory.GetFiles(Path.GetDirectoryName(dialog.FileName));

foreach (string file in filePaths)
{   
    if (comboBox1.SelectedItem.ToString() == "")
    {
        if (file.Contains("c"))
        {
            comboBox2.Items.Add(Path.GetFileName(file));
        }
    }
}

it should be as simple as

DateTime.Today

PS> Get-CimInstance -ComputerName bobPC win32_logicaldisk | where caption -eq "C:" | foreach-object {write " $($_.caption) $('{0:N2}' -f ($_.Size/1gb)) GB total, $('{0:N2}' -f ($_.FreeSpace/1gb)) GB free "}

Working with Spring Boot

Solution

Put the string below in .application.properties

spring.jpa.properties.hibernate.id.new_generator_mappings=false

Explanation

On Hibernate 4.X this attribute defaults to true.

From this MSDN article:

There is some overhead associated with creating a StringBuilder object, both in time and memory. On a machine with fast memory, a StringBuilder becomes worthwhile if you're doing about five operations. As a rule of thumb, I would say 10 or more string operations is a justification for the overhead on any machine, even a slower one.

So if you trust MSDN go with StringBuilder if you have to do more than 10 strings operations/concatenations - otherwise simple string concat with '+' is fine.

I contend that images (files) are NOT usually stored in a database base64 encoded. Instead, they are stored in their raw binary form in a binary (blob) column (or file).

Base64 is only used as a transport mechanism, not for storage. For example, you can embed a base64 encoded image into an XML document or an email message.

Base64 is also stream friendly. You can encode and decode on the fly (without knowing the total size of the data).

While base64 is fine for transport, do not store your images base64 encoded.

Base64 provides no checksum or anything of any value for storage.

Base64 encoding increases the storage requirement by 33% over a raw binary format. It also increases the amount of data that must be read from persistent storage, which is still generally the largest bottleneck in computing. It's generally faster to read less bytes and encode them on the fly. Only if your system is CPU bound instead of IO bound, and you're regularly outputting the image in base64, then consider storing in base64.

Inline images (base64 encoded images embedded in HTML) are a bottleneck themselves--you're sending 33% more data over the wire, and doing it serially (the web browser has to wait on the inline images before it can finish downloading the page HTML).

If you still wish to store images base64 encoded, please, whatever you do, make sure you don't store base64 encoded data in a UTF8 column then index it.

First of all, your description is misleading. Double is a floating point data type. You presumably want to pad your digits with leading zeros in a string. The following code does that:

$s = sprintf('%02d', $digit);

For more information, refer to the documentation of sprintf.

This XML file does not appear to have any style information associated with it. The document tree is shown below.

You will get this error in the client side when the client (the webbrowser) for some reason interprets the HTTP response content as text/xml instead of text/html and the parsed XML tree doesn't have any XML-stylesheet. In other words, the webbrowser incorrectly parsed the retrieved HTTP response content as XML instead of as HTML due to the wrong or missing HTTP response content type.

In case of JSF/Facelets files which have the default extension of .xhtml, that can in turn happen if the HTTP request hasn't invoked the FacesServlet and thus it wasn't able to parse the Facelets file and generate the desired HTML output based on the XHTML source code. Firefox is then merely guessing the HTTP response content type based on the .xhtml file extension which is in your Firefox configuration apparently by default interpreted as text/xml.

You need to make sure that the HTTP request URL, as you see in browser's address bar, matches the <url-pattern> of the FacesServlet as registered in webapp's web.xml, so that it will be invoked and be able to generate the desired HTML output based on the XHTML source code. If it's for example *.jsf, then you need to open the page by /some.jsf instead of /some.xhtml. Alternatively, you can also just change the <url-pattern> to *.xhtml. This way you never need to fiddle with virtual URLs.

See also:

• JSF Facelets: Sometimes I see the URL is .jsf and sometimes .xhtml. Why?

Note thus that you don't actually need a XML stylesheet. This all was just misinterpretation by the webbrowser while trying to do its best to make something presentable out of the retrieved HTTP response content. It should actually have retrieved the properly generated HTML output, Firefox surely knows precisely how to deal with HTML content.

Sort of combined the first two answers, with a tweak to ironfroggy's code so that it returns a tuple:

import operator

class stuple(tuple):
    def __add__(self, other):
        return self.__class__(map(operator.add, self, other))
        # obviously leaving out checking lengths

>>> a = stuple([1,2,3])
>>> b = stuple([3,2,1])
>>> a + b
(4, 4, 4)

Note: using self.__class__ instead of stuple to ease subclassing.

You can log all queries:

$ mongo
MongoDB shell version: 2.4.9
connecting to: test

> db.getProfilingLevel()
2
> db.system.profile.find().pretty()

Source: http://docs.mongodb.org/manual/reference/method/db.setProfilingLevel/

db.setProfilingLevel(2) means "log all operations".

I looked into this as well, and after comparing the SqlDataAdapter.Fill method with the SqlDataReader.Load funcitons, I've found that the SqlDataAdapter.Fill method is more than twice as fast with the result sets I've been using

Used code:

    [TestMethod]
    public void SQLCommandVsAddaptor()
    {
        long AdapterFillLargeTableTime, readerLoadLargeTableTime, AdapterFillMediumTableTime, readerLoadMediumTableTime, AdapterFillSmallTableTime, readerLoadSmallTableTime, AdapterFillTinyTableTime, readerLoadTinyTableTime;

        string LargeTableToFill = "select top 10000 * from FooBar";
        string MediumTableToFill = "select top 1000 * from FooBar";
        string SmallTableToFill = "select top 100 * from FooBar";
        string TinyTableToFill = "select top 10 * from FooBar";

        using (SqlConnection sconn = new SqlConnection("Data Source=.;initial catalog=Foo;persist security info=True; user id=bar;password=foobar;"))
        {
            // large data set measurements
            AdapterFillLargeTableTime = MeasureExecutionTimeMethod(sconn, LargeTableToFill, ExecuteDataAdapterFillStep);
            readerLoadLargeTableTime = MeasureExecutionTimeMethod(sconn, LargeTableToFill, ExecuteSqlReaderLoadStep);
            // medium data set measurements
            AdapterFillMediumTableTime = MeasureExecutionTimeMethod(sconn, MediumTableToFill, ExecuteDataAdapterFillStep);
            readerLoadMediumTableTime = MeasureExecutionTimeMethod(sconn, MediumTableToFill, ExecuteSqlReaderLoadStep);
            // small data set measurements
            AdapterFillSmallTableTime = MeasureExecutionTimeMethod(sconn, SmallTableToFill, ExecuteDataAdapterFillStep);

Sql Data Reader  100 times table load speed 10000 rows: 26047 milliseconds
1000 rows:
Sql Data Adapter 100 times table fill speed 1000 rows: 984  milliseconds
Sql Data Reader  100 times table load speed 1000 rows: 2031 milliseconds
100 rows:
Sql Data Adapter 100 times table fill speed 100 rows: 125 milliseconds
Sql Data Reader  100 times table load speed 100 rows: 235 milliseconds
10 rows:
Sql Data Adapter 100 times table fill speed 10 rows: 32 milliseconds
Sql Data Reader  100 times table load speed 10 rows: 93 milliseconds

For performance issues, using the SqlDataAdapter.Fill method is far more efficient. So unless you want to shoot yourself in the foot use that. It works faster for small and large data sets.

Use r.URL.Query() when you appending to existing query, if you are building new set of params use the url.Values struct like so

package main

import (
    "fmt"
    "log"
    "net/http"
    "net/url"
    "os"
)

func main() {
    req, err := http.NewRequest("GET","http://api.themoviedb.org/3/tv/popular", nil)
    if err != nil {
        log.Print(err)
        os.Exit(1)
    }

    // if you appending to existing query this works fine 
    q := req.URL.Query()
    q.Add("api_key", "key_from_environment_or_flag")
    q.Add("another_thing", "foo & bar")

    // or you can create new url.Values struct and encode that like so
    q := url.Values{}
    q.Add("api_key", "key_from_environment_or_flag")
    q.Add("another_thing", "foo & bar")

    req.URL.RawQuery = q.Encode()

    fmt.Println(req.URL.String())
    // Output:
    // http://api.themoviedb.org/3/tv/popularanother_thing=foo+%26+bar&api_key=key_from_environment_or_flag
}

My few cents to previous excellent replies. the site www.sqlite.org works on a sqlite database. Here is the link when the author (Richard Hipp) replies to a similar question.

To follow unobtrusive JavaScript programming conventions, and depending on how quickly the DOM will load, it may be a good idea to use the following:

<form onsubmit="return false;"></form>

Then wire up events using the onload or DOM ready if you're using a library.

$(function() {_x000D_
    var $form = $('#my-form');_x000D_
    $form.removeAttr('onsubmit');_x000D_
    $form.submit(function(ev) {_x000D_
        // quick validation example..._x000D_
        $form.children('input[type="text"]').each(function(){_x000D_
            if($(this).val().length == 0) {_x000D_
                alert('You are missing a field');_x000D_
                ev.preventDefault();_x000D_
            }_x000D_
        });_x000D_
    });_x000D_
});

label {_x000D_
    display: block;_x000D_
}_x000D_
_x000D_
#my-form > input[type="text"] {_x000D_
    background: cyan;_x000D_
}

<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>_x000D_
<form id="my-form" action="http://google.com" method="GET" onsubmit="return false;">_x000D_
    <label>Your first name</label>_x000D_
    <input type="text" name="first-name"/>_x000D_
    <label>Your last name</label>_x000D_
    <input type="text" name="last-name" /> <br />_x000D_
    <input type="submit" />_x000D_
</form>

Also, I would always use the action attribute as some people may have some plugin like NoScript running which would then break the validation. If you're using the action attribute, at the very least your user will get redirected by the server based on the backend validation. If you're using something like window.location, on the other hand, things will be bad.

Since TypeScript 3.7 was released you can use optional chaining now.

Property example:

let x = foo?.bar.baz();

This is equvalent to:

let x = (foo === null || foo === undefined) ?
    undefined :
    foo.bar.baz();

Moreover you can call:

Optional Call

function(otherFn: (par: string) => void) {
   otherFn?.("some value");
}

otherFn will be called only if otherFn won't be equal to null or undefined

Usage optional chaining in IF statement

This:

if (someObj && someObj.someProperty) {
    // ...
}

can be replaced now with this

if (someObj?.someProperty) {
    // ...
}

Ref. https://www.typescriptlang.org/docs/handbook/release-notes/typescript-3-7.html

This can be done without explicitly using hooks provided you add a prop to your component and a state to the stateless component's parent component:

const ParentComponent = props => {
  const [updateNow, setUpdateNow] = useState(true)

  const updateFunc = () => {
    setUpdateNow(!updateNow)
  }

  const MyComponent = props => {
    return (<div> .... </div>)
  }

  const MyButtonComponent = props => {
    return (<div> <input type="button" onClick={props.updateFunc} />.... </div>)
  }

  return (
    <div> 
      <MyComponent updateMe={updateNow} />
      <MyButtonComponent updateFunc={updateFunc}/>
    </div>
  )
}

You could just re-direct specific numbers in your contacts to your voice-mail. That's already supported.

Otherwise I guess the documentation for 'Contacts' would be a good place to start looking.

I think there a better alternative to the answers as of 2019. We can use the global-tunnel-ng package to initialize proxy and not pollute the http or https based code everywhere. So first install global-tunnel-ng package:

npm install global-tunnel-ng

Then change your implementations to initialize proxy if needed as:

const globalTunnel = require('global-tunnel-ng');

globalTunnel.initialize({
  host: 'proxy.host.name.or.ip',
  port: 8080
});

Just throwing this in in case it helps, I had this issue and the reason for me was because when I bundled my Angular stuff I referenced the main app file as "AngularWebApp" instead of "AngularWebApp.js", hope this helps.

NSString *myString = @"hello bla bla";
NSRange rangeValue = [myString rangeOfString:@"hello" options:NSCaseInsensitiveSearch];

if (rangeValue.length > 0)
{
    NSLog(@"string contains hello");
} 
else 
{
    NSLog(@"string does not contain hello!");
}

//You can alternatively use following too :

if (rangeValue.location == NSNotFound) 
{
    NSLog(@"string does not contain hello");
} 
else 
{
    NSLog(@"string contains hello!");
}

There exists various algorithms for the inverse cumulative normal distribution. The most popular in quantitative finance are tested on http://chasethedevil.github.io/post/monte-carlo-inverse-cumulative-normal-distribution/

In my opinion, there is not much incentive to use something else than algorithm AS241 from Wichura: it is machine precision, reliable and fast. Bottlenecks are rarely in the Gaussian random number generation.

The top answer here advocates for Box-Müller, you should be aware that it has known deficiencies. I quote https://www.sciencedirect.com/science/article/pii/S0895717710005935:

in the literature, Box–Muller is sometimes regarded as slightly inferior, mainly for two reasons. First, if one applies the Box–Muller method to numbers from a bad linear congruential generator, the transformed numbers provide an extremely poor coverage of the space. Plots of transformed numbers with spiraling tails can be found in many books, most notably in the classic book of Ripley, who was probably the first to make this observation"

public class IntergerParser {

public static void main(String[] args){
String number = "+123123";
System.out.println(parseInt(number));
}

private static int parseInt(String number){
    char[] numChar = number.toCharArray();
    int intValue = 0;
    int decimal = 1;
    for(int index = numChar.length ; index > 0 ; index --){
        if(index == 1 ){
            if(numChar[index - 1] == '-'){
                return intValue * -1;
            } else if(numChar[index - 1] == '+'){
                return intValue;
            }
        }
        intValue = intValue + (((int)numChar[index-1] - 48) * (decimal));
        System.out.println((int)numChar[index-1] - 48+ " " + (decimal));
        decimal = decimal * 10;
    }
    return intValue;
}

Use the checked attribute.

<input type="radio" name="imgsel"  value="" checked /> 

or

<input type="radio" name="imgsel"  value="" checked="checked" /> 

1.

To_Date(To_Char(MaxDate, 'DD/MM/YYYY')) = REP_DATE

is causing the issue. when you use to_date without the time format, oracle will use the current sessions NLS format to convert, which in your case might not be "DD/MM/YYYY". Check this...

SQL> select sysdate from dual;

SYSDATE
---------
26-SEP-12

Which means my session's setting is DD-Mon-YY

SQL> select to_char(sysdate,'MM/DD/YYYY') from dual;

TO_CHAR(SY
----------
09/26/2012


SQL> select to_date(to_char(sysdate,'MM/DD/YYYY')) from dual;
select to_date(to_char(sysdate,'MM/DD/YYYY')) from dual
               *
ERROR at line 1:
ORA-01843: not a valid month

SQL> select to_date(to_char(sysdate,'MM/DD/YYYY'),'MM/DD/YYYY') from dual;

TO_DATE(T
---------
26-SEP-12

2.

More importantly, Why are you converting to char and then to date, instead of directly comparing

MaxDate = REP_DATE

If you want to ignore the time component in MaxDate before comparision, you should use..

trunc(MaxDate ) = rep_date

instead.

==Update : based on updated question.

Rep_Date = 01/04/2009 Rep_Time = 01/01/1753 13:00:00

I think the problem is more complex. if rep_time is intended to be only time, then you cannot store it in the database as a date. It would have to be a string or date to time interval or numerically as seconds (thanks to Alex, see this) . If possible, I would suggest using one column rep_date that has both the date and time and compare it to the max date column directly.

If it is a running system and you have no control over repdate, you could try this.

trunc(rep_date) = trunc(maxdate) and 
to_char(rep_date,'HH24:MI:SS') = to_char(maxdate,'HH24:MI:SS')

Either way, the time is being stored incorrectly (as you can tell from the year 1753) and there could be other issues going forward.

In my case, database returned latin1, when my browser expected utf8.

So for MySQLi I did:

 mysqli_set_charset($dblink, "utf8");    

See http://php.net/manual/en/mysqli.set-charset.php for more info

It's declaring the string as nvarchar data type, rather than varchar

You may have seen Transact-SQL code that passes strings around using an N prefix. This denotes that the subsequent string is in Unicode (the N actually stands for National language character set). Which means that you are passing an NCHAR, NVARCHAR or NTEXT value, as opposed to CHAR, VARCHAR or TEXT.

To quote from Microsoft:

Prefix Unicode character string constants with the letter N. Without the N prefix, the string is converted to the default code page of the database. This default code page may not recognize certain characters.

If you want to know the difference between these two data types, see this SO post:

What is the difference between varchar and nvarchar?

This can be done similarly in Python using lists, (note that the whole list is shuffled in place).

import random

with open("datafile.txt", "rb") as f:
    data = f.read().split('\n')

random.shuffle(data)

train_data = data[:50]
test_data = data[50:]

Use the attribute onkeyup="myFunction()" in the <input> of your html.

This appears to be my "preferred" solution:

<form action="www.spufalcons.com/index.aspx?tab=gymnastics&path=gym" method="post">  <div>
<input type="submit" value="Gymnastics"></div>

Sorry for the presentation format - I'm still trying to learn how to use this forum....

I do have a follow-up question. In looking at my MySQL database of URL's it appears that ~30% of the URL's will need to use this post/div wrapper approach. This leaves ~70% that cannot accept the "post" attribute. For example:

<form action="http://www.google.com" method="post">
  <div>
    <input type="submit" value="Google"/>
  </div></form>

does not work. Do you have a recommendation for how to best handle this get/post condition test. Off the top of my head I'm guessing that using PHP to evaluate the existence of the "?" character in the URL may be my best approach, although I'm not sure how to structure the HTML form to accomplish this.

Thank YOU!

The issue for you is that you are using mm. You should use MM. MM is for month and mm is for minutes. Try with yyyy-MM-dd HH:mm

Other approach:

It can be as simple as this (other option is to use joda-time)

static final long ONE_MINUTE_IN_MILLIS=60000;//millisecs

Calendar date = Calendar.getInstance();
long t= date.getTimeInMillis();
Date afterAddingTenMins=new Date(t + (10 * ONE_MINUTE_IN_MILLIS));

Try with this solution: http://phppot.com/php/sorting-mysql-row-order-using-jquery/ where new order is saved in some HMTL element. Then you submit the form with this data to some PHP script, and iterate trough it with for loop.

Note: I had to add another db field of type INT(11) which is updated(timestamp'ed) on each iteration - it serves for script to know which row is recenty updated, or else you end up with scrambled results.

null is not an object, it is a primitive value. For example, you cannot add properties to it. Sometimes people wrongly assume that it is an object, because typeof null returns "object". But that is actually a bug (that might even be fixed in ECMAScript 6).

The difference between null and undefined is as follows:

• undefined: used by JavaScript and means “no value”. Uninitialized variables, missing parameters and unknown variables have that value.

  > var noValueYet;
  > console.log(noValueYet);
  undefined
  
  > function foo(x) { console.log(x) }
  > foo()
  undefined
  
  > var obj = {};
  > console.log(obj.unknownProperty)
  undefined
  

  Accessing unknown variables, however, produces an exception:

  > unknownVariable
  ReferenceError: unknownVariable is not defined
  

• null: used by programmers to indicate “no value”, e.g. as a parameter to a function.

Examining a variable:

console.log(typeof unknownVariable === "undefined"); // true

var foo;
console.log(typeof foo === "undefined"); // true
console.log(foo === undefined); // true

var bar = null;
console.log(bar === null); // true

As a general rule, you should always use === and never == in JavaScript (== performs all kinds of conversions that can produce unexpected results). The check x == null is an edge case, because it works for both null and undefined:

> null == null
true
> undefined == null
true

A common way of checking whether a variable has a value is to convert it to boolean and see whether it is true. That conversion is performed by the if statement and the boolean operator ! (“not”).

function foo(param) {
    if (param) {
        // ...
    }
}
function foo(param) {
    if (! param) param = "abc";
}
function foo(param) {
    // || returns first operand that can't be converted to false
    param = param || "abc";
}

Drawback of this approach: All of the following values evaluate to false, so you have to be careful (e.g., the above checks can’t distinguish between undefined and 0).

• undefined, null
• Booleans: false
• Numbers: +0, -0, NaN
• Strings: ""

You can test the conversion to boolean by using Boolean as a function (normally it is a constructor, to be used with new):

> Boolean(null)
false
> Boolean("")
false
> Boolean(3-3)
false
> Boolean({})
true
> Boolean([])
true

Follow this :

1. File > Preferences > setting
2. In search type -> git path
3. Now scroll down a little > you will see "Git:path" section.
4. Click "Edit in settings.json".
5. Now just paste this path there "C:\\Program Files\\Git\\mingw64\\libexec\\git-core\\git.exe"

Restart VSCode and open new terminal in VSCode and try "git version"

In case still problem exists :

1. Inside terminal click on terminal options (1:Poweshell)
2. Select default shell
3. Select bash

open new terminal and change terminal option to 2:Bash Again try "git version" - this should work :)

personally I had a similar issue and went with something like this:

function getLastRowinColumn (ws, column) {
  var page_lastrow = ws.getDataRange().getNumRows();
  var last_row_col = 0
  for (i=1; i<=page_lastrow;i++) {
    if (!(spread.getRange(column.concat("",i)).isBlank())) {last_row_col = i};
  }
  return last_row_col
}

It looks for the number of rows in the ws and loops through each cell in your column. When it finds a non-empty cell it updates the position of that cell in the last_row_col variable. It has the advantage of allowing you to have non-contiguous columns and still know the last row (assuming you are going through the whole column).

David's answer is correct, but if it's still a little abstract, here are two examples:

1. You might want to zero all freed pointers to catch memory problems earlier. C-style you'd do:

   void freeAndZero(void** ptr)
   {
       free(*ptr);
       *ptr = 0;
   }
   
   void* ptr = malloc(...);
   
   ...
   
   freeAndZero(&ptr);
   

   In C++ to do the same, you might do:

   template<class T> void freeAndZero(T* &ptr)
   {
       delete ptr;
       ptr = 0;
   }
   
   int* ptr = new int;
   
   ...
   
   freeAndZero(ptr);
   

2. When dealing with linked-lists - often simply represented as pointers to a next node:

   struct Node
   {
       value_t value;
       Node* next;
   };
   

   In this case, when you insert to the empty list you necessarily must change the incoming pointer because the result is not the NULL pointer anymore. This is a case where you modify an external pointer from a function, so it would have a reference to pointer in its signature:

   void insert(Node* &list)
   {
       ...
       if(!list) list = new Node(...);
       ...
   }
   

There's an example in this question.

Public Class Form1

    Private animatedimage As New Bitmap("C:\MyData\Search.gif")
    Private currentlyanimating As Boolean = False

    Private Sub OnFrameChanged(ByVal sender As System.Object, ByVal e As System.EventArgs)

        Me.Invalidate()

    End Sub

    Private Sub AnimateImage()

        If currentlyanimating = True Then
            ImageAnimator.Animate(animatedimage, AddressOf Me.OnFrameChanged)
            currentlyanimating = False
        End If

    End Sub

    Protected Overrides Sub OnPaint(ByVal e As System.Windows.Forms.PaintEventArgs)

        AnimateImage()
        ImageAnimator.UpdateFrames(animatedimage)
        e.Graphics.DrawImage(animatedimage, New Point((Me.Width / 4) + 40, (Me.Height / 4) + 40))

    End Sub

    Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load

        BtnStop.Enabled = False

        BtnStart.Enabled = True
        BtnStop.Enabled = False

    End Sub

        currentlyanimating = True
        AnimateImage()
        BtnStart.Enabled = False
        BtnStop.Enabled = True

    End Sub

End Class

I think this is the shortest SQL statement for that:

CREATE FUNCTION [dbo].[fn_stripsingleQuote] (@strStrip varchar(Max))
    RETURNS varchar(Max)
AS
BEGIN    
    RETURN (Replace(@strStrip ,'''',''))
END

I hope this helps!

The main reason I used Reflector (and, I think, the main reason most people used it) was for its decompiler: it can translate a method's IL back into source code.

On that count, Monoflector would be the project to watch. It uses Cecil, which does the reflection, and Cecil.Decompiler, which does the decompilation. But Monoflector layers a UI on top of both libraries, which should give you a very good idea of how to use the API.

Monoflector is also a decent alternative to Reflector outright. It lets you browse the types and decompile the methods, which is 99% of what people used Reflector for. It's very rough around the edges, but I'm thinking that will change quickly.

On Python 3 you can use the itertools islice to slice the dict.items() iterator

import itertools

d = {1: 2, 3: 4, 5: 6}

dict(itertools.islice(d.items(), 2))

{1: 2, 3: 4}

Note: this solution does not take into account specific keys. It slices by internal ordering of d, which in Python 3.7+ is guaranteed to be insertion-ordered.

You can use the sDom option for this.

Default with search input in its own div:

sDom: '<"search-box"r>lftip'

If you use jQuery UI (bjQueryUI set to true):

sDom: '<"search-box"r><"H"lf>t<"F"ip>'

The above will put the search/filtering input element into it's own div with a class named search-box that is outside of the actual table.

Even though it uses its special shorthand syntax it can actually take any HTML you throw at it.

Take a look QRCoder - pure C# open source QR code generator. Can be used in three lines of code

QRCodeGenerator qrGenerator = new QRCodeGenerator();
QRCodeGenerator.QRCode qrCode = qrGenerator.CreateQrCode(textBoxQRCode.Text, QRCodeGenerator.ECCLevel.Q);
pictureBoxQRCode.BackgroundImage = qrCode.GetGraphic(20);

Here's a different approach. The heart of it was created by turning on the Macro Recorder and filtering the columns per your specifications. Then there's a bit of code to copy the results. It will run faster than looping through each row and column:

Sub FilterAndCopy()
Dim LastRow As Long

Sheets("Sheet2").UsedRange.Offset(0).ClearContents
With Worksheets("Sheet1")
    .Range("$A:$E").AutoFilter
    .Range("$A:$E").AutoFilter field:=1, Criteria1:="#N/A"
    .Range("$A:$E").AutoFilter field:=2, Criteria1:="=String1", Operator:=xlOr, Criteria2:="=string2"
    .Range("$A:$E").AutoFilter field:=3, Criteria1:=">0"
    .Range("$A:$E").AutoFilter field:=5, Criteria1:="Number"
    LastRow = .Range("A" & .Rows.Count).End(xlUp).Row
    .Range("A1:A" & LastRow).SpecialCells(xlCellTypeVisible).EntireRow.Copy _
            Destination:=Sheets("Sheet2").Range("A1")
End With
End Sub

As a side note, your code has more loops and counter variables than necessary. You wouldn't need to loop through the columns, just through the rows. You'd then check the various cells of interest in that row, much like you did.

Rows("2:2").Select
ActiveWindow.FreezePanes = True

Select a different range for a different effect, much the same way you would do manually. The "Freeze Top Row" really just is a shortcut new in Excel 2007 (and up), it contains no added functionality compared to earlier versions of Excel.

A CASE statement is an expression, just like a boolean comparison. That means the 'AND' needs to go before the 'CASE' statement, not within it.:

Select * From Times
WHERE (StartDate <= @Date) AND (EndDate >= @Date)

AND -- Added the "AND" here

CASE WHEN @day = 'Monday' THEN (Monday = 1)   -- Removed "AND" 
    WHEN @day = 'Tuesday' THEN (Tuesday = 1)  -- Removed "AND" 
    ELSE AND (Wednesday = 1) 
END

replace() method will work for this. Here is the code that will help to remove character from string. lets say

j_word = 'Stringtoremove'
word = 'String'    

for letter in word:
    if j_word.find(letter) == -1:
        continue
    else:
       # remove matched character
       j_word = j_word.replace(letter, '', 1)

#Output
j_word = "toremove"

Don't fret too much if your initial API is fully RESTful or not (specially when you are just in the alpha stages). Get the back-end plumbing to work first. You can always do some sort of URL transformation/re-writing to map things out, refining iteratively until you get something stable enough for widespread testing ("beta").

You can define URIs whose parameters are encoded by position and convention on the URIs themselves, prefixed by a path you know you'll always map to something. I don't know PHP, but I would assume that such a facility exists (as it exists in other languages with web frameworks):

.ie. Do a "user" type of search with param[i]=value[i] for i=1..4 on store #1 (with value1,value2,value3,... as a shorthand for URI query parameters):

1) GET /store1/search/user/value1,value2,value3,value4

or

2) GET /store1/search/user,value1,value2,value3,value4

or as follows (though I would not recommend it, more on that later)

3) GET /search/store1,user,value1,value2,value3,value4

With option 1, you map all URIs prefixed with /store1/search/user to the search handler (or whichever the PHP designation) defaulting to do searches for resources under store1 (equivalent to /search?location=store1&type=user.

By convention documented and enforced by the API, parameters values 1 through 4 are separated by commas and presented in that order.

Option 2 adds the search type (in this case user) as positional parameter #1. Either option is just a cosmetic choice.

Option 3 is also possible, but I don't think I would like it. I think the ability of search within certain resources should be presented in the URI itself preceding the search itself (as if indicating clearly in the URI that the search is specific within the resource.)

The advantage of this over passing parameters on the URI is that the search is part of the URI (thus treating a search as a resource, a resource whose contents can - and will - change over time.) The disadvantage is that parameter order is mandatory.

Once you do something like this, you can use GET, and it would be a read-only resource (since you can't POST or PUT to it - it gets updated when it's GET'ed). It would also be a resource that only comes to exist when it is invoked.

One could also add more semantics to it by caching the results for a period of time or with a DELETE causing the cache to be deleted. This, however, might run counter to what people typically use DELETE for (and because people typically control caching with caching headers.)

How you go about it would be a design decision, but this would be the way I'd go about. It is not perfect, and I'm sure there will be cases where doing this is not the best thing to do (specially for very complex search criteria).

This is how I toggle two divs at the same time:

It works!

For managed tables, Hive controls the lifecycle of their data. Hive stores the data for managed tables in a sub-directory under the directory defined by hive.metastore.warehouse.dir by default.

When we drop a managed table, Hive deletes the data in the table.But managed tables are less convenient for sharing with other tools. For example, lets say we have data that is created and used primarily by Pig , but we want to run some queries against it, but not give Hive ownership of the data.

At that time, external table is defined that points to that data, but doesn’t take ownership of it.

The solutions suggested by S.Mark and SilentGhost generally tell you how it should be done in a Pythonic way, but I thought you might also benefit from knowing why your solution doesn't work. The problem is that as soon as you find the first common element in the two lists, you return that single element only. Your solution could be fixed by creating a result list and collecting the common elements in that list:

def common_elements(list1, list2):
    result = []
    for element in list1:
        if element in list2:
            result.append(element)
    return result

An even shorter version using list comprehensions:

def common_elements(list1, list2):
    return [element for element in list1 if element in list2]

However, as I said, this is a very inefficient way of doing this -- Python's built-in set types are way more efficient as they are implemented in C internally.

Your data types are mismatched when you are retrieving the field values.

Also check how you store your enums, default is ORDINAL (numeric value stored in database), but STRING (name of enum stored in database) is also an option. Make sure the Entity in your code and the Model in your database are exactly the same.

I had an enum mismatch. It was set to default (ORDINAL) but the database model was expecting a string VARCHAR2(100char). Solution: @Enumerated(EnumType.STRING)

As far as I read manual pages, scanf says that 'l' length modifier indicates (in case of floating points) that the argument is of type double rather than of type float, so you can have 'lf, le, lg'.

As for printing, officially, the manual says that 'l' applies only to integer types. So it might be not supported on some systems or by some standards. For instance, I get the following error message when compiling with gcc -Wall -Wextra -pedantic

a.c:6:1: warning: ISO C90 does not support the ‘%lf’ gnu_printf format [-Wformat=]

So you may want to doublecheck if your standard supports the syntax.

To conclude, I would say that you read with '%lf' and you print with '%f'.

I think you are not configured properly,

if you are using XAMPP then you can easily send mail from localhost.

for example you can configure C:\xampp\php\php.ini and c:\xampp\sendmail\sendmail.ini for gmail to send mail.

in C:\xampp\php\php.ini find extension=php_openssl.dll and remove the semicolon from the beginning of that line to make SSL working for gmail for localhost.

in php.ini file find [mail function] and change

SMTP=smtp.gmail.com
smtp_port=587
sendmail_from = [email protected]
sendmail_path = "C:\xampp\sendmail\sendmail.exe -t"

(use the above send mail path only and it will work)

Now Open C:\xampp\sendmail\sendmail.ini. Replace all the existing code in sendmail.ini with following code

[sendmail]

smtp_server=smtp.gmail.com
smtp_port=587
error_logfile=error.log
debug_logfile=debug.log
[email protected]
auth_password=my-gmail-password
[email protected]

Now you have done!! create php file with mail function and send mail from localhost.

Update

First, make sure you PHP installation has SSL support (look for an "openssl" section in the output from phpinfo()).

You can set the following settings in your PHP.ini:

ini_set("SMTP","ssl://smtp.gmail.com");
ini_set("smtp_port","465");

suppose you have a button:

<button onclick="backBtn();">Back...</button>

Here the code of the backBtn method:

  function backBtn(){
                    parent.history.back();
                    return false;
                }

public class ForEachLoopExample {

    public static void main(String[] args) {

        System.out.println("For Each Loop Example: ");

        int[] intArray = { 1,2,3,4,5 };

        //Here iteration starts from index 0 to last index
        for(int i : intArray)
            System.out.println(i);
    }

}

var countries = ['United States', 'Canada', 'Argentina', 'Armenia'];
var cList = $('ul.mylist')
$.each(countries, function(i)
{
    var li = $('<li/>')
        .addClass('ui-menu-item')
        .attr('role', 'menuitem')
        .appendTo(cList);
    var aaa = $('<a/>')
        .addClass('ui-all')
        .text(countries[i])
        .appendTo(li);
});

With the recent release of bootstrap 3, and the glyphicons being merged back to the main Bootstrap repo, Bootstrap CDN is now serving the complete Bootstrap 3.0 css including Glyphicons. The Bootstrap css reference is all you need to include: Glyphicons and its dependencies are on relative paths on the CDN site and are referenced in bootstrap.min.css.

In html:

<link href="//netdna.bootstrapcdn.com/bootstrap/3.0.0/css/bootstrap.min.css" rel="stylesheet">

In css:

 @import url("//netdna.bootstrapcdn.com/bootstrap/3.0.0/css/bootstrap.min.css");

Here is a working demo.

Note that you have to use .glyphicon classes instead of .icon:

Example:

<span class="glyphicon glyphicon-heart"></span>

Also note that you would still need to include bootstrap.min.js for usage of Bootstrap JavaScript components, see Bootstrap CDN for url.

If you want to use the Glyphicons separately, you can do that by directly referencing the Glyphicons css on Bootstrap CDN.

In html:

<link href="//netdna.bootstrapcdn.com/bootstrap/3.0.0/css/bootstrap-glyphicons.css" rel="stylesheet">

In css:

@import url("//netdna.bootstrapcdn.com/bootstrap/3.0.0/css/bootstrap-glyphicons.css");

Since the css file already includes all the needed Glyphicons dependencies (which are in a relative path on the Bootstrap CDN site), adding the css file is all there is to do to start using Glyphicons.

Here is a working demo of the Glyphicons without Bootstrap.

This is simple way to convert files to Base64 and avoid "maximum call stack size exceeded at FileReader.reader.onload" with the file has big size.

document.querySelector('#fileInput').addEventListener('change',   function () {_x000D_
_x000D_
    var reader = new FileReader();_x000D_
    var selectedFile = this.files[0];_x000D_
_x000D_
    reader.onload = function () {_x000D_
        var comma = this.result.indexOf(',');_x000D_
        var base64 = this.result.substr(comma + 1);_x000D_
        console.log(base64);_x000D_
    }_x000D_
    reader.readAsDataURL(selectedFile);_x000D_
}, false);

<input id="fileInput" type="file" />
