I think you've actually got a wider confusion here.

The initial error is that you're trying to call split on the whole list of lines, and you can't split a list of strings, only a string. So, you need to split each line, not the whole thing.

And then you're doing for points in Type, and expecting each such points to give you a new x and y. But that isn't going to happen. Types is just two values, x and y, so first points will be x, and then points will be y, and then you'll be done. So, again, you need to loop over each line and get the x and y values from each line, not loop over a single Types from a single line.

So, everything has to go inside a loop over every line in the file, and do the split into x and y once for each line. Like this:

def getQuakeData():
    filename = input("Please enter the quake file: ")
    readfile = open(filename, "r")

    for line in readfile:
        Type = line.split(",")
        x = Type[1]
        y = Type[2]
        print(x,y)

getQuakeData()

As a side note, you really should close the file, ideally with a with statement, but I'll get to that at the end.

Interestingly, the problem here isn't that you're being too much of a newbie, but that you're trying to solve the problem in the same abstract way an expert would, and just don't know the details yet. This is completely doable; you just have to be explicit about mapping the functionality, rather than just doing it implicitly. Something like this:

def getQuakeData():
    filename = input("Please enter the quake file: ")
    readfile = open(filename, "r")
    readlines = readfile.readlines()
    Types = [line.split(",") for line in readlines]
    xs = [Type[1] for Type in Types]
    ys = [Type[2] for Type in Types]
    for x, y in zip(xs, ys):
        print(x,y)

getQuakeData()

Or, a better way to write that might be:

def getQuakeData():
    filename = input("Please enter the quake file: ")
    # Use with to make sure the file gets closed
    with open(filename, "r") as readfile:
        # no need for readlines; the file is already an iterable of lines
        # also, using generator expressions means no extra copies
        types = (line.split(",") for line in readfile)
        # iterate tuples, instead of two separate iterables, so no need for zip
        xys = ((type[1], type[2]) for type in types)
        for x, y in xys:
            print(x,y)

getQuakeData()

Finally, you may want to take a look at NumPy and Pandas, libraries which do give you a way to implicitly map functionality over a whole array or frame of data almost the same way you were trying to.

There is no difference between both, AS is just a more explicit way of mentioning the alias which is good because some dependent libraries depends on this small keyword. e.g. JDBC 4.0. Depend on use of it, different behaviour can be observed.

See this. I would always suggest to use the full form of semantic to avoid such issues.

This is not as short as the other examples, but takes an entirely different approach to solving this problem. Note, the caret will still begin flush to the left edge but the text will be properly indented when typed/displayed. This works without subclassing if your looking for just a left margin and you are already using UITextFieldDelegate for your text fields. You need to set both the default text attributes and the typing attributes. You set the default text attributes when you create the text field. The typing attributes you need to set in the delegate. If you are also using a placeholder you will want to set that to the same margin as well. Putting it altogether you get something like this.

First create a category on the UITextField class.

//  UITextField+TextAttributes.h

#import <UIKit/UIKit.h>

@interface UITextField (TextAttributes)

- (void)setIndent:(CGFloat)indent;

@end


//  UITextField+TextAttributes.m
#import "UITextField+TextAttributes.h"

@implementation UITextField (TextAttributes)

- (void)setTextAttributes:(NSDictionary*)textAttributes indent:(CGFloat)indent
{
    if (!textAttributes) return;

    NSMutableParagraphStyle *paragraphStyle = [textAttributes objectForKey:NSParagraphStyleAttributeName];
    paragraphStyle.firstLineHeadIndent = indent;
    paragraphStyle.headIndent = indent;
}

- (void)setIndent:(CGFloat)indent
{
   [self setTextAttributes:self.defaultTextAttributes indent:indent];
   [self setTextAttributes:self.typingAttributes indent:indent];
}

@end

Then, if you are using placed holders make sure to use an attributed placeholder setting the same indent. Create a default attributed dictionary with the proper attributes, something like this:

NSMutableParagraphStyle *paragraphStyle = [[NSMutableParagraphStyle alloc] init];
paragraphStyle.firstLineHeadIndent = 7;
paragraphStyle.headIndent = 7;
NSDictionary *placeholderAttributes = [NSDictionary dictionaryWithObjectsAndKeys: paragraphStyle, NSParagraphStyleAttributeName, nil];

Then, import the above category and whenever you create a text field set the default indent, the delegate and use the default placeholder attributes defined above. For example:

UITextField *textField = [[UITextField alloc] init];
textField.indent = 7;
textField.delegate = self;
textField.attributedPlaceholder = [[NSAttributedString alloc] initWithString:@"Placeholder Text" attributes:placeholderAttributes];

Lastly, in the delegate, implement the textFieldDidBeginEditing method, something like this:

- (void)textFieldDidBeginEditing:(UITextField *)textField
{
    textField.indent = 7;
}

In my case, .Net Core 3.0 API in Startup.cs, in method

public void ConfigureServices(IServiceCollection services)

I had to add

services.AddScoped<IStateService, StateService>();

If you do not want to handle separate properties for each possible argument, I suggest you'd use:

<arg line="${args}"/>

You can check if the property is not set using a specific target with an unless attribute and inside do:

<input message="Type the desired command line arguments:" addProperty="args"/>

Putting it all together gives:

<target name="run" depends="compile, input-runargs" description="run the project">
  <!-- You can use exec here, depending on your needs -->
  <java classname="Main">
    <arg line="${args}"/>
  </java>
</target>
<target name="input-runargs" unless="args" description="prompts for command line arguments if necessary">
  <input addProperty="args" message="Type the desired command line arguments:"/>
</target>

You can use it as follows:

ant
ant run
ant run -Dargs='--help'

The first two commands will prompt for the command-line arguments, whereas the latter won't.

If possible, you'd be better off handling the load event within the iframe's document and calling out to a function in the containing document. This has the advantage of working in all browsers and only running once.

In the main document:

function iframeLoaded() {
    alert("Iframe loaded!");
}

In the iframe document:

window.onload = function() {
    parent.iframeLoaded();
}

Square brackets are meant for character class, and you're actually trying to match any one of: s, |, s (again), e, a, s (again), o and n.

Use parentheses instead for grouping:

(s|season)

or non-capturing group:

(?:s|season)

Note: Non-capture groups tell the engine that it doesn't need to store the match, while the other one (capturing group does). For small stuff, either works, for 'heavy duty' stuff, you might want to see first if you need the match or not. If you don't, better use the non-capture group to allocate more memory for calculation instead of storing something you will never need to use.

Example of solution with reflection, passed method must be public

import java.lang.reflect.Method;
import java.lang.reflect.InvocationTargetException;

public class Program {
    int i;

    public static void main(String[] args) {
        Program   obj = new Program();    //some object

        try {
            Method method = obj.getClass().getMethod("target");
            repeatMethod( 5, obj, method );
        } 
        catch ( NoSuchMethodException | IllegalAccessException | InvocationTargetException e) {
            System.out.println( e ); 
        }
    }

    static void repeatMethod (int times, Object object, Method method)
        throws IllegalAccessException, InvocationTargetException {

        for (int i=0; i<times; i++)
            method.invoke(object);
    }
    public void target() {                 //public is necessary
        System.out.println("target(): "+ ++i);
    }
}

I came across this question, and the answers here didn't work for me; i couldn't figure out why i can't login and got the above error.

It turns out that postgresql saves usernames lowercase, but during authentication it uses both upper- and lowercase.

CREATE USER myNewUser WITH PASSWORD 'passWord';

will create a user with the username 'mynewuser' and password 'passWord'.

This means you have to authenticate with 'mynewuser', and not with 'myNewUser'. For a newbie in pgsql like me, this was confusing. I hope it helps others who run into this problem.

The capitalization is wrong, and you have an extra argument.

Do this instead:

$('img#thumb').removeAttr('id');

For future reference, there aren't any jQuery methods that begin with a capital letter. They all take the same form as this one, starting with a lower case, and the first letter of each joined "word" is upper case.

you can use this code as template please customize it as per your requirement.

DefaultTableModel model = new DefaultTableModel();
List<String> list = new ArrayList<String>();

list.add(textField.getText());
list.add(comboBox.getSelectedItem());

model.addRow(list.toArray());

table.setModel(model);

here DefaultTableModel is used to add rows in JTable, you can get more info here.

You can use built-in sorted function.

print sorted(['Stem', 'constitute', 'Sedge', 'Eflux', 'Whim', 'Intrigue'])

Is this any help?

#include <stdio.h>

#define MAX 10

int main()
{
    char grid[MAX][MAX];
    int i,j,row,col;

    printf("Please enter your grid size: ");
    scanf("%d %d", &row, &col);


    for (i = 0; i < row; i++) {
        for (j = 0; j < col; j++) {
            grid[i][j] = '.';
            printf("%c ", grid[i][j]);
        }
        printf("\n");
    }

    return 0;
}

I played a bit with it and the syntax seems to get quite strange when a constructor takes no arguments. Let me give an example:

#include <iostream> 

using namespace std;

class Thing
{
public:
    Thing();
};

Thing::Thing()
{
    cout << "Hi" << endl;
}

int main()
{
    //Thing myThing(); // Does not work
    Thing myThing; // Works

}

so just writing Thing myThing w/o brackets actually calls the constructor, while Thing myThing() makes the compiler thing you want to create a function pointer or something ??!!

If you load the document in Chrome, the Developer|Elements view will show you the HTML as fiddled by your JS code. It's not directly HTML text and you have to open (unfold) any elements of interest, but you effectively get to inspect the generated HTML.

You are not currently on a branch. To push the history leading to the current (detached HEAD) state now, use

git push origin HEAD:<name-of-remote-branch>

(I'm assuming you mean browser-side JavaScript)

Ask him why, despite his infinite knowledge of JavaScript, it is still a good idea to use existing frameworks such as jQuery, Mootools, Prototype, etc.

Answer: Good coders code, great coders reuse. Thousands of man hours have been poured into these libraries to abstract DOM capabilities away from browser specific implementations. There's no reason to go through all of the different browser DOM headaches yourself just to reinvent the fixes.

If you're running Angular 2 through ASP.NET Core 1 in Visual Studio 2015, you might find this solution from Jürgen Gutsch helpful. He describes it in a blog post. It was the best solution for me. Place the C# code provided below in your Startup.cs public void Configure() just before app.UseStaticFiles();

app.Use( async ( context, next ) => {
    await next();

    if( context.Response.StatusCode == 404 && !Path.HasExtension( context.Request.Path.Value ) ) {
        context.Request.Path = "/index.html";
        await next();
    }
});

you just provide one <folder> argument to npm install, argument should point toward the local folder instead of the package name:

npm install /path

Only tested on Android 4.1.1:

blur event is not a reliable event to test keyboard up and down because the user as the option to explicitly hide the keyboard which does not trigger a blur event on the field that caused the keyboard to show.

resize event however works like a charm if the keyboard comes up or down for any reason.

coffee:

$(window).bind "resize", (event) ->  alert "resize"

fires on anytime the keyboard is shown or hidden for any reason.

Note however on in the case of an android browser (rather than app) there is a retractable url bar which does not fire resize when it is retracted yet does change the available window size.

This is more complex than some other solutions, but may offer more flexibility in scenarios:

1) Make a class definition to isolate (encapsulate) the styling you want to apply/remove selectively. It can be empty (and for this case, probably should be):

.myColor {}

2) use this code, based on http://jsfiddle.net/kdp5V/167/ from this answer by gilly3:

function changeCSSRule(styleSelector,property,value) {
    for (var ssIdx = 0; ssIdx < document.styleSheets.length; ssIdx++) {
        var ss = document.styleSheets[ssIdx];
        var rules = ss.cssRules || ss.rules;
        if(rules){
            for (var ruleIdx = 0; ruleIdx < rules.length; ruleIdx++) {
                var rule = rules[ruleIdx];
                if (rule.selectorText == styleSelector) {
                    if(typeof value == 'undefined' || !value){
                        rule.style.removeProperty(property);
                    } else {
                        rule.style.setProperty(property,value);
                    }
                    return; // stops at FIRST occurrence of this styleSelector
                }
            }
        }
    }
}

Usage example: http://jsfiddle.net/qvkwhtow/

Caveats:

• Not extensively tested.
• Can't include !important or other directives in the new value. Any such existing directives will be lost through this manipulation.
• Only changes first found occurrence of a styleSelector. Doesn't add or remove entire styles, but this could be done with something more elaborate.
• Any invalid/unusable values will be ignored or throw error.
• In Chrome (at least), non-local (as in cross-site) CSS rules are not exposed through document.styleSheets object, so this won't work on them. One would have to add a local overrides and manipulate that, keeping in mind the "first found" behavior of this code.
• document.styleSheets is not particularly friendly to manipulation in general, don't expect this to work for aggressive use.

Isolating the styling this way is what CSS is all about, even if manipulating it isn't. Manipulating CSS rules is NOT what jQuery is all about, jQuery manipulates DOM elements, and uses CSS selectors to do it.

To check if a string does not contain any whitespaces, you can use

string.matches("^\\S*$")

Example:

"name"        -> true
"  "          -> false
"name xxname" -> false

Your problem is that class B is not declared as a "new-style" class. Change it like so:

class B(object):

and it will work.

super() and all subclass/superclass stuff only works with new-style classes. I recommend you get in the habit of always typing that (object) on any class definition to make sure it is a new-style class.

Old-style classes (also known as "classic" classes) are always of type classobj; new-style classes are of type type. This is why you got the error message you saw:

TypeError: super() argument 1 must be type, not classobj

Try this to see for yourself:

class OldStyle:
    pass

class NewStyle(object):
    pass

print type(OldStyle)  # prints: <type 'classobj'>

print type(NewStyle) # prints <type 'type'>

Note that in Python 3.x, all classes are new-style. You can still use the syntax from the old-style classes but you get a new-style class. So, in Python 3.x you won't have this problem.

If the commit you want to fix isn’t the most recent one:

1. git rebase --interactive $parent_of_flawed_commit

   If you want to fix several flawed commits, pass the parent of the oldest one of them.

2. An editor will come up, with a list of all commits since the one you gave.

   1. Change pick to reword (or on old versions of Git, to edit) in front of any commits you want to fix.
   2. Once you save, Git will replay the listed commits.
      
      

3. For each commit you want to reword, Git will drop you back into your editor. For each commit you want to edit, Git drops you into the shell. If you’re in the shell:

   1. Change the commit in any way you like.
   2. git commit --amend
   3. git rebase --continue

Most of this sequence will be explained to you by the output of the various commands as you go. It’s very easy; you don’t need to memorise it – just remember that git rebase --interactive lets you correct commits no matter how long ago they were.

Note that you will not want to change commits that you have already pushed. Or maybe you do, but in that case you will have to take great care to communicate with everyone who may have pulled your commits and done work on top of them. How do I recover/resynchronise after someone pushes a rebase or a reset to a published branch?

I looked at my Environment Variables and had a System Variable called _JAVA_OPTIONS with the value -Xms256m -Xmx512m, after changing this to -Xms256m -Xmx1024m the max heap size increased accordingly.

Had same issue, after installing java using below lines solved the issue !

sudo add-apt-repository ppa:webupd8team/java
sudo apt-get update
sudo apt-get install oracle-java8-installer

I do something like this: See this GitHub Example

spl_autoload_register('AutoLoader');

function AutoLoader($className)
{
    $file = str_replace('\\',DIRECTORY_SEPARATOR,$className);

    require_once 'classes' . DIRECTORY_SEPARATOR . $file . '.php'; 
    //Make your own path, Might need to use Magics like ___DIR___
}

OK it's 2019 now, and from Java 11 you have a constructor with Charset:

FileWriter?(String fileName, Charset charset)

Unfortunately, we still cannot modify the byte buffer size, and it's set to 8192. (https://www.baeldung.com/java-filewriter)

We can change the default parallelism using the following property:

-Djava.util.concurrent.ForkJoinPool.common.parallelism=16

which can set up to use more parallelism.

This question will answer how to encrypt/decrypt: Encrypt and decrypt a string in C#?

You didn't specify a database, but you will want to base-64 encode it, using Convert.toBase64String. For an example you can use: http://www.opinionatedgeek.com/Blog/blogentry=000361/BlogEntry.aspx

You'll then either save it in a varchar or a blob, depending on how long your encrypted message is, but for a password varchar should work.

The examples above will also cover decryption after decoding the base64.

UPDATE:

In actuality you may not need to use base64 encoding, but I found it helpful, in case I wanted to print it, or send it over the web. If the message is long enough it's best to compress it first, then encrypt, as it is harder to use brute-force when the message was already in a binary form, so it would be hard to tell when you successfully broke the encryption.

$computer,$Speed,$Regcheck will create an array, and run out-file ones per variable = they get seperate lines. If you construct a single string using the variables first, it will show up a single line. Like this:

"$computer,$Speed,$Regcheck" | out-file -filepath C:\temp\scripts\pshell\dump.txt -append -width 200

You need to put \n in the file string.xml

<string name="strtextparkcar">press Park my Car to store location \n</string>

i had the same issue. go to Sql Server Configuration management->SQL Server network config->protocols for 'servername' and check named pipes is enabled.

There is a new docker command for "secrets" management. But that only works for swarm clusters.

docker service create
--name my-iis
--publish target=8000,port=8000
--secret src=homepage,target="\inetpub\wwwroot\index.html"
microsoft/iis:nanoserver 

You need to install ssh2 lib

sudo apt-get install libssh2-php && sudo /etc/init.d/apache2 restart

that should be enough to get you on the road

You need to pass IP/hostname of the rempote machine in the connection string.

import java.sql.*;
import javax.sql.*;

public class Connect
{
   public static void main (String[] args)
   {
       Connection conn = null;

       try
       {

           String url = "jdbc:mysql://localhost:3306/mydb";
           Class.forName ("com.mysql.jdbc.Driver");
           conn = DriverManager.getConnection (url,"root"," ");
           System.out.println ("Database connection established");
       }
       catch (Exception e)
       {
           e.printStackTrace();

       }
       finally
       {
           if (conn != null)
           {
               try
               {
                   conn.close ();
                   System.out.println ("Database connection terminated");
               }
               catch (Exception e) { /* ignore close errors */ }
           }
       }

}

This question contains some useful links on headless builds, but they are mostly geared towards building plugins. I'm not sure how much of it can be applied to pure Java projects.

You can write this

class Human {
    private firstName : string;
    private lastName : string;

    constructor (
        public FirstName?:string, 
        public LastName?:string) {

    }

    get FirstName() : string {
        console.log("Get FirstName : ", this.firstName);
        return this.firstName;
    }
    set FirstName(value : string) {
        console.log("Set FirstName : ", value);
        this.firstName = value;
    } 

    get LastName() : string {
        console.log("Get LastName : ", this.lastName);
        return this.lastName;
    }
    set LastName(value : string) {
        console.log("Set LastName : ", value);
        this.lastName = value;
    } 

}

You can solve this by increasing the maximum request length in your web.config:

<?xml version="1.0" encoding="utf-8"?>
<configuration>
    <system.web>
        <httpRuntime maxRequestLength="102400" />
    </system.web>
</configuration>

The example above is for a 100Mb limit.

After considering and trying all of the other ways here, here's how I solved the issue in nodejs with the googleapis module in conjunction with the request module, which I used to fetch the tokens instead of the provided getToken() method:

const request = require('request');

//SETUP GOOGLE AUTH
var google = require('googleapis');
const oAuthConfigs = rootRequire('config/oAuthConfig')
const googleOAuthConfigs = oAuthConfigs.google

//for google OAuth: https://github.com/google/google-api-nodejs-client
var OAuth2 = google.auth.OAuth2;
var googleOAuth2Client = new OAuth2(
    process.env.GOOGLE_OAUTH_CLIENT_ID || googleOAuthConfigs.clientId, 
    process.env.GOOGLE_OAUTH_CLIENT_SECRET || googleOAuthConfigs.clientSecret, 
    process.env.GOOGLE_OAUTH_CLIENT_REDIRECT_URL || googleOAuthConfigs.callbackUrl);

/* generate a url that asks permissions for Google+ and Google Calendar scopes
https://developers.google.com/identity/protocols/googlescopes#monitoringv3*/
var googleOAuth2ClientScopes = [
    'https://www.googleapis.com/auth/plus.me',
    'https://www.googleapis.com/auth/userinfo.email'
];

var googleOAuth2ClientRedirectURL = process.env.GOOGLE_OAUTH_CLIENT_REDIRECT_URL || googleOAuthConfigs.callbackUrl; 

var googleOAuth2ClientAuthUrl = googleOAuth2Client.generateAuthUrl({
  access_type: 'offline', // 'online' (default) or 'offline' (gets refresh_token)
  scope: googleOAuth2ClientScopes // If you only need one scope you can pass it as string
});

//AFTER SETUP, THE FOLLOWING IS FOR OBTAINING TOKENS FROM THE AUTHCODE


        const ci = process.env.GOOGLE_OAUTH_CLIENT_ID || googleOAuthConfigs.clientId
        const cs = process.env.GOOGLE_OAUTH_CLIENT_SECRET || googleOAuthConfigs.clientSecret
        const ru = process.env.GOOGLE_OAUTH_CLIENT_REDIRECT_URL || googleOAuthConfigs.callbackUrl
        var oauth2Client = new OAuth2(ci, cs, ru);

        var hostUrl = "https://www.googleapis.com";
        hostUrl += '/oauth2/v4/token?code=' + authCode + '&client_id=' + ci + '&client_secret=' + cs + '&redirect_uri=' + ru + '&grant_type=authorization_code',
        request.post({url: hostUrl}, function optionalCallback(err, httpResponse, data) {
            // Now tokens contains an access_token and an optional refresh_token. Save them.
            if(!err) {
                //SUCCESS! We got the tokens
                const tokens = JSON.parse(data)
                oauth2Client.setCredentials(tokens);

                //AUTHENTICATED PROCEED AS DESIRED.
                googlePlus.people.get({ userId: 'me', auth: oauth2Client }, function(err, response) {
                // handle err and response
                    if(!err) {
                        res.status(200).json(response);
                    } else {
                        console.error("/google/exchange 1", err.message);
                        handleError(res, err.message, "Failed to retrieve google person");
                    }
                });
            } else {
                console.log("/google/exchange 2", err.message);
                handleError(res, err.message, "Failed to get access tokens", err.code);
            }
        });

You can set using SelectedIndex

comboBox1.SelectedIndex= 1;

OR

SelectedItem

comboBox1.SelectedItem = "your value"; // 

The latter won't throw an exception if the value is not available in the combobox

EDIT

If the value to be selected is not specific then you would be better off with this

comboBox1.SelectedIndex = comboBox1.Items.Count - 1;

Output is buffered.

stdout is line-buffered by default, which means that '\n' is supposed to flush the buffer. Why is it not happening in your case? I don't know. I need more info about your application/environment.

However, you can control buffering with setvbuf():

setvbuf(stdout, NULL, _IOLBF, 0);

This will force stdout to be line-buffered.

setvbuf(stdout, NULL, _IONBF, 0);

This will force stdout to be unbuffered, so you won't need to use fflush(). Note that it will severely affect application performance if you have lots of prints.

<html>
  <style>
.selectBox{
 color:White;
}
.optionBox{
  color:black;
}

</style>
<body>
<select class = "selectBox">
  <option class = "optionBox">One</option>
  <option class = "optionBox">Two</option>
  <option class = "optionBox">Three</option>
</select>

I would use underscore for this, but if that isn't available then I would drop down to using reduce with an initial value of empty object {}

>>> ['a', 'b', 'c'].reduce(function(p, c, i) {p[i] = c; return p}, {})
Object { 0="a", 1="b", 2="c"}

reduce should be widely available in most browsers today, see MDN

You need to leverage the @ViewChild decorator to reference the child component from the parent one by injection:

import { Component, ViewChild } from 'angular2/core';  

(...)

@Component({
  selector: 'my-app',
  template: `
    <h1>My First Angular 2 App</h1>
    <child></child>
    <button (click)="submit()">Submit</button>
  `,
  directives:[App]
})
export class AppComponent { 
  @ViewChild(Child) child:Child;

  (...)

  someOtherMethod() {
    this.searchBar.someMethod();
  }
}

Here is the updated plunkr: http://plnkr.co/edit/mrVK2j3hJQ04n8vlXLXt?p=preview.

You can notice that the @Query parameter decorator could also be used:

export class AppComponent { 
  constructor(@Query(Child) children:QueryList<Child>) {
    this.childcmp = children.first();
  }

  (...)
}

In order to distinct all datatable columns, you can easily retrieve the names of the columns in a string array

public static DataTable RemoveDuplicateRows(this DataTable dataTable)
{
    List<string> columnNames = new List<string>();
    foreach (DataColumn col in dataTable.Columns)
    {
        columnNames.Add(col.ColumnName);
    }
    return dataTable.DefaultView.ToTable(true, columnNames.Select(c => c.ToString()).ToArray());
}

As you can notice, I thought of using it as an extension to DataTable class

res.json forces the argument to JSON. res.send will take an non-json object or non-json array and send another type. For example:

This will return a JSON number.

res.json(100)

This will return a status code and issue a warning to use sendStatus.

res.send(100)

If your argument is not a JSON object or array (null,undefined,boolean,string), and you want to ensure it is sent as JSON, use res.json.

If you'd prefer a more direct approach, one that does NOT mess with symlinking between /etc/nginx/sites-available and /etc/nginx/sites-enabled, do the following:

1. Locate your nginx.conf file. Likely at /etc/nginx/nginx.conf
2. Find the http block.
3. Somewhere in the http block, write include /etc/nginx/conf.d/*.conf; This tells nginx to pull in any files in the conf.d directory that end in .conf. (I know: it's weird that a directory can have a . in it.)
4. Create the conf.d directory if it doesn't already exist (per the path in step 3). Be sure to give it the right permissions/ownership. Likely root or www-data.
5. Move or copy your separate config files (just like you have in /etc/nginx/sites-available) into the directory conf.d.
6. Reload or restart nginx.
7. Eat an ice cream cone.

Any .conf files that you put into the conf.d directory from here on out will become active as long as you reload/restart nginx after.

Note: You can use the conf.d and sites-enabled + sites-available method concurrently if you wish. I like to test on my dev box using conf.d. Feels faster than symlinking and unsymlinking.

Yes there is a difference between the functions but the way you are using them in this case will result in the same outcome.

path.join returns a normalized path by merging two paths together. It can return an absolute path, but it doesn't necessarily always do so.

For instance:

path.join('app/libs/oauth', '/../ssl')

resolves to app/libs/ssl

path.resolve, on the other hand, will resolve to an absolute path.

For instance, when you run:

path.resolve('bar', '/foo');

The path returned will be /foo since that is the first absolute path that can be constructed.

However, if you run:

path.resolve('/bar/bae', '/foo', 'test');

The path returned will be /foo/test again because that is the first absolute path that can be formed from right to left.

If you don't provide a path that specifies the root directory then the paths given to the resolve function are appended to the current working directory. So if your working directory was /home/mark/project/:

path.resolve('test', 'directory', '../back');

resolves to

/home/mark/project/test/back

Using __dirname is the absolute path to the directory containing the source file. When you use path.resolve or path.join they will return the same result if you give the same path following __dirname. In such cases it's really just a matter of preference.

If you want to open .img files, you can use 7-zip, which is freeware...

http://www.7-zip.org/

Once installed, right click on the relevant img file, hover over "7-zip", then click "Open Archive". Bear in mind, you need a seperate program, or Windows 7 to burn the image to disc!

Hope this helps!

Edit: Proof that it works (not my video, credit to howtodothe on YouTube).

HTML5 spec:

http://www.w3.org/TR/html5/forms.html#enabling-and-disabling-form-controls:-the-disabled-attribute :

The checked content attribute is a boolean attribute

http://www.w3.org/TR/html5/infrastructure.html#boolean-attributes :

The presence of a boolean attribute on an element represents the true value, and the absence of the attribute represents the false value.

If the attribute is present, its value must either be the empty string or a value that is an ASCII case-insensitive match for the attribute's canonical name, with no leading or trailing whitespace.

Conclusion:

The following are valid, equivalent and true:

<input type="text" disabled />
<input type="text" disabled="" />
<input type="text" disabled="disabled" />
<input type="text" disabled="DiSaBlEd" />

The following are invalid:

<input type="text" disabled="0" />
<input type="text" disabled="1" />
<input type="text" disabled="false" />
<input type="text" disabled="true" />

The absence of the attribute is the only valid syntax for false:

<input type="text" />

Recommendation

If you care about writing valid XHTML, use disabled="disabled", since <input disabled> is invalid and other alternatives are less readable. Else, just use <input disabled> as it is shorter.

The message means that both the packages have functions with the same names. In this particular case, the testthat and assertive packages contain five functions with the same name.

When two functions have the same name, which one gets called?

R will look through the search path to find functions, and will use the first one that it finds.

search()
 ##  [1] ".GlobalEnv"        "package:assertive" "package:testthat" 
 ##  [4] "tools:rstudio"     "package:stats"     "package:graphics" 
 ##  [7] "package:grDevices" "package:utils"     "package:datasets" 
 ## [10] "package:methods"   "Autoloads"         "package:base"

In this case, since assertive was loaded after testthat, it appears earlier in the search path, so the functions in that package will be used.

is_true
## function (x, .xname = get_name_in_parent(x)) 
## {
##     x <- coerce_to(x, "logical", .xname)
##     call_and_name(function(x) {
##         ok <- x & !is.na(x)
##         set_cause(ok, ifelse(is.na(x), "missing", "false"))
##     }, x)
## }
<bytecode: 0x0000000004fc9f10>
<environment: namespace:assertive.base>

The functions in testthat are not accessible in the usual way; that is, they have been masked.

What if I want to use one of the masked functions?

You can explicitly provide a package name when you call a function, using the double colon operator, ::. For example:

testthat::is_true
## function () 
## {
##     function(x) expect_true(x)
## }
## <environment: namespace:testthat>

How do I suppress the message?

If you know about the function name clash, and don't want to see it again, you can suppress the message by passing warn.conflicts = FALSE to library.

library(testthat)
library(assertive, warn.conflicts = FALSE)
# No output this time

Alternatively, suppress the message with suppressPackageStartupMessages:

library(testthat)
suppressPackageStartupMessages(library(assertive))
# Also no output

Impact of R's Startup Procedures on Function Masking

If you have altered some of R's startup configuration options (see ?Startup) you may experience different function masking behavior than you might expect. The precise order that things happen as laid out in ?Startup should solve most mysteries.

For example, the documentation there says:

Note that when the site and user profile files are sourced only the base package is loaded, so objects in other packages need to be referred to by e.g. utils::dump.frames or after explicitly loading the package concerned.

Which implies that when 3rd party packages are loaded via files like .Rprofile you may see functions from those packages masked by those in default packages like stats, rather than the reverse, if you loaded the 3rd party package after R's startup procedure is complete.

How do I list all the masked functions?

First, get a character vector of all the environments on the search path. For convenience, we'll name each element of this vector with its own value.

library(dplyr)
envs <- search() %>% setNames(., .)

For each environment, get the exported functions (and other variables).

fns <- lapply(envs, ls)

Turn this into a data frame, for easy use with dplyr.

fns_by_env <- data_frame(
  env = rep.int(names(fns), lengths(fns)),
  fn  = unlist(fns)
)

Find cases where the object appears more than once.

fns_by_env %>% 
  group_by(fn) %>% 
  tally() %>% 
  filter(n > 1) %>% 
  inner_join(fns_by_env)

To test this, try loading some packages with known conflicts (e.g., Hmisc, AnnotationDbi).

How do I prevent name conflict bugs?

The conflicted package throws an error with a helpful error message, whenever you try to use a variable with an ambiguous name.

library(conflicted)
library(Hmisc)
units
## Error: units found in 2 packages. You must indicate which one you want with ::
##  * Hmisc::units
##  * base::units

Matlab and Scilab languages offer a simpler and more elegant syntax than Python for the question you're asking, so I think the best you can do is to mimic Matlab/Scilab by using the Numpy package in Python. By doing this the solution to your problem is very concise and elegant:

from numpy import *
property_a = array([545., 656., 5.4, 33.])
property_b = array([ 1.2,  1.3, 2.3, 0.3])
good_objects = [True, False, False, True]
good_indices = [0, 3]
property_asel = property_a[good_objects]
property_bsel = property_b[good_indices]

Numpy tries to mimic Matlab/Scilab but it comes at a cost: you need to declare every list with the keyword "array", something which will overload your script (this problem doesn't exist with Matlab/Scilab). Note that this solution is restricted to arrays of number, which is the case in your example.

# COLUMN is integer column number
# INPUT_FILE is input file name

cut -f ${COLUMN} < ${INPUT_FILE} | sort -u | wc -l

Just another example how to achieve desired effect

class Foo(object):

    _bar = None

    @property
    def bar(self):
        return self._bar

    @bar.setter
    def bar(self, value):
        self._bar = value

    def __init__(self, dyn_property_name):
        setattr(Foo, dyn_property_name, Foo.bar)

So now we can do stuff like:

>>> foo = Foo('baz')
>>> foo.baz = 5
>>> foo.bar
5
>>> foo.baz
5

This works for me https://www.nuget.org/packages/ASquare.WindowsTaskScheduler/

It is nicely designed Fluent API.

//This will create Daily trigger to run every 10 minutes for a duration of 18 hours
SchedulerResponse response = WindowTaskScheduler
    .Configure()
    .CreateTask("TaskName", "C:\\Test.bat")
    .RunDaily()
    .RunEveryXMinutes(10)
    .RunDurationFor(new TimeSpan(18, 0, 0))
    .SetStartDate(new DateTime(2015, 8, 8))
    .SetStartTime(new TimeSpan(8, 0, 0))
    .Execute();

just use like this to make anything to center

 android:layout_gravity="center"
 android:gravity="center"

updated :

android:layout_gravity="center|right"
android:gravity="center|right"

Updated : Just remove MarginBottom from your textview.. Do like this.. for your textView

<LinearLayout
        android:id="@+id/linearLayout5"
        android:layout_width="fill_parent"
        android:layout_height="wrap_content"
        android:layout_gravity="center"  >

        <TextView
            android:id="@+id/textView2"
            android:layout_width="fill_parent"
            android:layout_height="wrap_content"
            android:layout_gravity="center" 
            android:gravity="center|right"
            android:text="hello" 
            android:textSize="20dp" />
    </LinearLayout>

CASE WHEN B.[STAT] IS NULL THEN (C.[EVENT DATE]+10)   -- Type DATETIME
     ELSE '-'                                         -- Type VARCHAR
     END AS [DATE]

You need to select one type or the other for the field, the field type can't vary by row. The simplest is to remove the ELSE '-' and let it implicitly get the value NULL instead for the second case.

"I'm looking for the fastest way to determine if a long value is a perfect square (i.e. its square root is another integer)."

The answers are impressive, but I failed to see a simple check :

check whether the first number on the right of the long it a member of the set (0,1,4,5,6,9) . If it is not, then it cannot possibly be a 'perfect square' .

eg.

4567 - cannot be a perfect square.

The rowSums function (as Greg mentions) will do what you want, but you are mixing subsetting techniques in your answer, do not use "$" when using "[]", your code should look something more like:

data$new <- rowSums( data[,43:167] )

If you want to use a function other than sum, then look at ?apply for applying general functions accross rows or columns.

I used this set up in a react app that works. I created a config file named configstrp.js that contains the following:

module.exports = {
ngrok: {
// use the local frontend port to connect
enabled: process.env.NODE_ENV !== 'production',
port: process.env.PORT || 3000,
subdomain: process.env.NGROK_SUBDOMAIN,
authtoken: process.env.NGROK_AUTHTOKEN
},   }

Require the file in the server.

const configstrp      = require('./config/configstrp.js');
const ngrok = configstrp.ngrok.enabled ? require('ngrok') : null;

and connect as such

if (ngrok) {
console.log('If nGronk')
ngrok.connect(
    {
    addr: configstrp.ngrok.port,
    subdomain: configstrp.ngrok.subdomain,
    authtoken: configstrp.ngrok.authtoken,
    host_header:3000
  },
  (err, url) => {
    if (err) {

    } else {

    }
   }
  );
 }

Do not pass a subdomain if you do not have a custom domain

@Dinh Nhat, your setter method looks wrong because you put a primitive type there again and it should be:

public void setClient_os_id(Integer clientOsId) {
client_os_id = clientOsId;
}

The problem with all the previous answers is that the hover image isn't loaded with the page so when the browser calls it, it takes time to load and the whole thing doesn't look really good.

What I do is that I put the original image and the hover image in 1 element and hide the hover image at first. Then at hover in I display the hover image and hide the old one, and at hover out I do the opposite.

HTML:

<span id="bellLogo" onmouseover="hvr(this, 'in')" onmouseleave="hvr(this, 'out')">
  <img src="stylesheets/images/bell.png" class=bell col="g">
  <img src="stylesheets/images/bell_hover.png" class=bell style="display:none" col="b">
</span>

JavaScript/jQuery:

function hvr(dom, action)
{
    if (action == 'in')
    {
        $(dom).find("[col=g]").css("display", "none");
        $(dom).find("[col=b]").css("display", "inline-block");
    }

    else
    {
        $(dom).find("[col=b]").css("display", "none");
        $(dom).find("[col=g]").css("display", "inline-block");
    }
}

This to me is the easiest and most efficient way to do it.

You could check out JBoss Tools plugin.

I am late for this but i want put some more solution relevant to this.

 @GetMapping
public ResponseEntity<List<JSONObject>> getRole() {
    return ResponseEntity.ok(service.getRole());
}

i would recommend you to you datagridview, for heavy stuff.. it's include a lot of auto feature listviwe does not

extract($_POST);
$error=array();
$extension=array("jpeg","jpg","png","gif");
foreach($_FILES["files"]["tmp_name"] as $key=>$tmp_name) {
    $file_name=$_FILES["files"]["name"][$key];
    $file_tmp=$_FILES["files"]["tmp_name"][$key];
    $ext=pathinfo($file_name,PATHINFO_EXTENSION);

    if(in_array($ext,$extension)) {
        if(!file_exists("photo_gallery/".$txtGalleryName."/".$file_name)) {
            move_uploaded_file($file_tmp=$_FILES["files"]["tmp_name"][$key],"photo_gallery/".$txtGalleryName."/".$file_name);
        }
        else {
            $filename=basename($file_name,$ext);
            $newFileName=$filename.time().".".$ext;
            move_uploaded_file($file_tmp=$_FILES["files"]["tmp_name"][$key],"photo_gallery/".$txtGalleryName."/".$newFileName);
        }
    }
    else {
        array_push($error,"$file_name, ");
    }
}

and you must check your HTML code

<form action="create_photo_gallery.php" method="post" enctype="multipart/form-data">
    <table width="100%">
        <tr>
            <td>Select Photo (one or multiple):</td>
            <td><input type="file" name="files[]" multiple/></td>
        </tr>
        <tr>
            <td colspan="2" align="center">Note: Supported image format: .jpeg, .jpg, .png, .gif</td>
        </tr>
        <tr>
            <td colspan="2" align="center"><input type="submit" value="Create Gallery" id="selectedButton"/></td>
        </tr>
    </table>
</form>

Well you can simply use this piece of code in your scss file; This will remove that unwanted color change,

a:-webkit-any-link {
  &:hover {
    color: white;
  }
}

Here's what Oracle's documentation has to say:

By default the heap dump is created in a file called java_pid.hprof in the working directory of the VM, as in the example above. You can specify an alternative file name or directory with the -XX:HeapDumpPath= option. For example -XX:HeapDumpPath=/disk2/dumps will cause the heap dump to be generated in the /disk2/dumps directory.

I got tired of this problem myself, so I wrote a package called automodinit to fix it. You can get it from http://pypi.python.org/pypi/automodinit/.

Usage is like this:

1. Include the automodinit package into your setup.py dependencies.
2. Replace all __init__.py files like this:

__all__ = ["I will get rewritten"]
# Don't modify the line above, or this line!
import automodinit
automodinit.automodinit(__name__, __file__, globals())
del automodinit
# Anything else you want can go after here, it won't get modified.

That's it! From now on importing a module will set __all__ to a list of .py[co] files in the module and will also import each of those files as though you had typed:

for x in __all__: import x

Therefore the effect of "from M import *" matches exactly "import M".

automodinit is happy running from inside ZIP archives and is therefore ZIP safe.

I thought it could be worthwhile to have a micro-benchmark comparing the run-times of the different approaches mentioned here.

Disclaimer: I'm using simple_benchmark (a library written by me) for the benchmarks and also include iteration_utilities.count_items (a function in a third-party-library written by me).

To provide a more differentiated result I've done two benchmarks, one only including the approaches that don't build an intermediate container just to throw it away and one including these:

from simple_benchmark import BenchmarkBuilder
import more_itertools as mi
import iteration_utilities as iu

b1 = BenchmarkBuilder()
b2 = BenchmarkBuilder()

@b1.add_function()
@b2.add_function()
def summation(it):
    return sum(1 for _ in it)

@b1.add_function()
def len_list(it):
    return len(list(it))

@b1.add_function()
def len_listcomp(it):
    return len([_ for _ in it])

@b1.add_function()
@b2.add_function()
def more_itertools_ilen(it):
    return mi.ilen(it)

@b1.add_function()
@b2.add_function()
def iteration_utilities_count_items(it):
    return iu.count_items(it)

@b1.add_arguments('length')
@b2.add_arguments('length')
def argument_provider():
    for exp in range(2, 18):
        size = 2**exp
        yield size, [0]*size

r1 = b1.run()
r2 = b2.run()

import matplotlib.pyplot as plt

f, (ax1, ax2) = plt.subplots(2, 1, sharex=True, figsize=[15, 18])
r1.plot(ax=ax2)
r2.plot(ax=ax1)
plt.savefig('result.png')

The results were:

It uses log-log-axis so that all ranges (small values, large values) can be inspected. Since the plots are intended for qualitative comparison the actual values aren't too interesting. In general the y-axis (vertical) represents the time and the x-axis (horizontal) represents the number of elements in the input "iterable". Lower on the vertical axis means faster.

The upper plot shows the approaches where no intermediate list was used. Which shows that the iteration_utilities approach was fastest, followed by more_itertools and the slowest was using sum(1 for _ in iterator).

The lower plot also included the approaches that used len() on an intermediate list, once with list and once with a list comprehension. The approach with len(list) was fastest here, but the difference to the iteration_utilities approach is almost negligible. The approach using the comprehension was significantly slower than using list directly.

Summary

Any approach mentioned here did show a dependency on the length of the input and iterated over ever element in the iterable. There is no way to get the length without the iteration (even if the iteration is hidden).

If you don't want third-party extensions then using len(list(iterable)) is definitely the fastest approach of the tested approaches, it however generates an intermediate list which could use significant more memory.

If you don't mind additional packages then iteration_utilities.count_items would be almost as fast as the len(list(...)) function but doesn't require additional memory.

However it's important to note that the micro-benchmark used a list as input. The result of the benchmark could be different depending on the iterable you want to get the length of. I also tested with range and a simple genertor-expression and the trends were very similar, however I cannot exclude that the timing won't change depending on the type of input.

I have no idea what linux distribution "ubuntu centOS" is. Ubuntu and CentOS are two different distributions.

To answer the question in the header: To install make in ubuntu you have to install build-essentials

sudo apt-get install build-essential

This is what actually worked for me on OSX Yosemite.

brew install cask
brew install Caskroom/cask/xquartz
brew install r

Convert PPK to OpenSSh

OS X: Install Homebrew, then run

brew install putty

Place your keys in some directory, e.g. your home folder. Now convert the PPK keys to SSH keypairs:cache search

To generate the private key:

cd ~

puttygen id_dsa.ppk -O private-openssh -o id_dsa

and to generate the public key:

puttygen id_dsa.ppk -O public-openssh -o id_dsa.pub

Move these keys to ~/.ssh and make sure the permissions are set to private for your private key:

mkdir -p ~/.ssh
mv -i ~/id_dsa* ~/.ssh
chmod 600 ~/.ssh/id_dsa
chmod 666 ~/.ssh/id_dsa.pub

connect with ssh server

ssh -i ~/.ssh/id_dsa username@servername

Port Forwarding to connect mysql remote server

ssh -i ~/.ssh/id_dsa -L 9001:127.0.0.1:3306 username@serverName

if you change Modifiers Property of a control in a Form to Public, another Forms can access to that control. f.e. :

    Form2 frm;

    {
        frm = new Form2();
        frm.Show();
    }
    private void button1_Click(object sender, EventArgs e)

I changed a few things to work with Option Explicit, and the code ran fine against a cell containing "abc.123", which returned "abc.12,". There were no compile errors.

Option Explicit ' This is new

Public Function ProcessString(input_string As String) As String
    ' The temp string used throughout the function
    Dim temp_string As String
    Dim i As Integer ' This is new
    Dim return_string As String ' This is new
    For i = 1 To Len(input_string)
        temp_string = Mid(input_string, i, 1)
        If temp_string Like "[A-Z, a-z, 0-9, :, -]" Then
            return_string = return_string & temp_string
        End If
    Next i
    return_string = Mid(return_string, 1, (Len(return_string) - 1))
    ProcessString = return_string & ", "
End Function

I'll suggest you post more of your relevant code (that calls this function). You've stated that last_name is a String, but it appears that may not be the case. Step through your code line by line and ensure that this is actually the case.

Swift 4+

extension String {
    func take(_ n: Int) -> String {
        guard n >= 0 else {
            fatalError("n should never negative")
        }
        let index = self.index(self.startIndex, offsetBy: min(n, self.count))
        return String(self[..<index])
    }
}

Returns a subsequence of the first n characters, or the entire string if the string is shorter. (inspired by: https://kotlinlang.org/api/latest/jvm/stdlib/kotlin.text/take.html)

Example:

let text = "Hello, World!"
let substring = text.take(5) //Hello

Java's Runtime object can report the JVM's memory usage. For CPU consumption you'll have to use an external utility, like Unix's top or Windows Process Manager.

I tried pretty much all the suggestions made here but none worked. For us the issue was temperamental and became worse and worse the larger the repos became (on our Jenkins Windows build slave).

It ended up being the version of ssh being used by git. Git was configured to use some version of Open SSH, specified in the users .gitconfig file via the core.sshCommand variable. Removing that line fixed it. I believe this is because Windows now ships with a more reliable / compatible version of SSH which gets used by default.

Two things you could do I think...

1. Create the System.Diagnostics.Process object manually and bypass Start-Process
2. Run the executable in a background job (only for non-interactive processes!)

Here's how you could do either:

$pinfo = New-Object System.Diagnostics.ProcessStartInfo
$pinfo.FileName = "notepad.exe"
$pinfo.RedirectStandardError = $true
$pinfo.RedirectStandardOutput = $true
$pinfo.UseShellExecute = $false
$pinfo.Arguments = ""
$p = New-Object System.Diagnostics.Process
$p.StartInfo = $pinfo
$p.Start() | Out-Null
#Do Other Stuff Here....
$p.WaitForExit()
$p.ExitCode

OR

Start-Job -Name DoSomething -ScriptBlock {
    & ping.exe somehost
    Write-Output $LASTEXITCODE
}
#Do other stuff here
Get-Job -Name DoSomething | Wait-Job | Receive-Job

$('your_select option:selected').next('option').prop('selected', true)

// simple approach

$original_id = 56789;

$shortened_id = base_convert($original_id, 10, 36);

$un_shortened_id = base_convert($shortened_id, 36, 10);

What is the accessibility of the type support.ACTInterface. The error suggests it is not public.

You cannot expose a public method signature where some of the parameter types of the signature are not public. It wouldn't be possible to call the method from outside since the caller couldn't construct the parameters required.

If you make support.ACTInterface public that will remove this error. Alternatively reduce the accessibility of the form method if possible.

var myNumber: number = 1200;_x000D_
//convert to hexadecimal value_x000D_
console.log(myNumber.toString(16)); //will return  4b0_x000D_
//Other way of converting to hexadecimal_x000D_
console.log(Math.abs(myNumber).toString(16)); //will return  4b0_x000D_

Probably the project you are running is not compatible (API version/Hardware requirements) with the emulator settings. Check in your build.gradle file if the targetSDK and minimumSdk version is lower or equal to the sdk version of your Emulator.

You should also uncheck Tools > Android > Enable ADB Integration

If your case is different then restart your Android Studio and run the emulator again.

First you have to copy, from AdapterArrayList to tempsearchnewArrayList ( Add ListView items into tempsearchnewArrayList ) , because then only you can compare whether search text is appears in Arraylist or not.

After creating temporary arraylist, add below code.

    searchEditTextBox.addTextChangedListener(new TextWatcher() {
        @Override
        public void beforeTextChanged(CharSequence charSequence, int i, int i1, int i2) {
        }
        @Override
        public void onTextChanged(CharSequence charSequence, int i, int i1, int i2) {
            String txt = charSequence.toString().trim();
            int txtlength = txt.length();
            if (txtlength > 0) {
                AdapterArrayList = new ArrayList<HashMap<String, String>>();
                for (int j = 0; j< tempsearchnewArrayList.size(); j++) {
                    if (tempsearchnewArrayList.get(j).get("type").toLowerCase().contains(txt)) {
                        AdapterArrayList.add(tempsearchnewArrayList.get(j));
                    }
                }
            } else {
                AdapterArrayList = new ArrayList<HashMap<String, String>>();
                AdapterArrayList.addAll(tempsearchnewArrayList);
            }
            adapter1.notifyDataSetChanged();
            if (AdapterArrayList.size() > 0) {
                mainactivitylistview.setAdapter(adapter1);
            } else {
                mainactivitylistview.setAdapter(null);
            }

        }
        @Override
        public void afterTextChanged(Editable editable) {

        }
    });

This constructor was deprecated in API level 26.1.0. use NotificationCompat.Builder(Context, String) instead. All posted Notifications must specify a NotificationChannel Id.

You can take timestamp snapshots before and after, then repeat the experiments several times to average to results. There are also profilers that can do this for you.

From "Java Platform Performance: Strategies and Tactics" book:

With System.currentTimeMillis()

class TimeTest1 {
   public static void main(String[] args) {

      long startTime = System.currentTimeMillis();

      long total = 0;
      for (int i = 0; i < 10000000; i++) {
         total += i;
      }

      long stopTime = System.currentTimeMillis();
      long elapsedTime = stopTime - startTime;
      System.out.println(elapsedTime);
   }
}

With a StopWatch class

You can use this StopWatch class, and call start() and stop before and after the method.

class TimeTest2 {
   public static void main(String[] args) {

      Stopwatch timer = new Stopwatch().start();

      long total = 0;
      for (int i = 0; i < 10000000; i++) {
         total += i;
      }

      timer.stop();
      System.out.println(timer.getElapsedTime());
   }
}

Look at strtok(). strtok() is not a re-entrant function.

strtok_r() is the re-entrant version of strtok(). Here's an example program from the manual:

   #include <stdio.h>
   #include <stdlib.h>
   #include <string.h>

   int main(int argc, char *argv[])
   {
       char *str1, *str2, *token, *subtoken;
       char *saveptr1, *saveptr2;
       int j;

       if (argc != 4) {
           fprintf(stderr, "Usage: %s string delim subdelim\n",argv[0]);
           exit(EXIT_FAILURE);
       }

       for (j = 1, str1 = argv[1]; ; j++, str1 = NULL) {
           token = strtok_r(str1, argv[2], &saveptr1);
           if (token == NULL)
               break;
           printf("%d: %s\n", j, token);

           for (str2 = token; ; str2 = NULL) {
               subtoken = strtok_r(str2, argv[3], &saveptr2);
               if (subtoken == NULL)
                   break;
               printf(" --> %s\n", subtoken);
           }
       }

       exit(EXIT_SUCCESS);
   }

Sample run which operates on subtokens which was obtained from the previous token based on a different delimiter:

$ ./a.out hello:word:bye=abc:def:ghi = :

1: hello:word:bye
 --> hello
 --> word
 --> bye
2: abc:def:ghi
 --> abc
 --> def
 --> ghi

Short answer (asked version): (format 3.33.20150710.182906)

Please, simple use a makefile with:

MAJOR = 3
MINOR = 33
BUILD = $(shell date +"%Y%m%d.%H%M%S")
VERSION = "\"$(MAJOR).$(MINOR).$(BUILD)\""
CPPFLAGS = -DVERSION=$(VERSION)

program.x : source.c
       gcc $(CPPFLAGS) source.c -o program.x

and if you don't want a makefile, shorter yet, just compile with:

gcc source.c -o program.x -DVERSION=\"2.22.$(date +"%Y%m%d.%H%M%S")\"

Short answer (suggested version): (format 150710.182906)

Use a double for version number:

MakeFile:

VERSION = $(shell date +"%g%m%d.%H%M%S")
CPPFLAGS = -DVERSION=$(VERSION)
program.x : source.c
      gcc $(CPPFLAGS) source.c -o program.x

Or a simple bash command:

$ gcc source.c -o program.x -DVERSION=$(date +"%g%m%d.%H%M%S")

Tip: Still don't like makefile or is it just for a not-so-small test program? Add this line:

 export CPPFLAGS='-DVERSION='$(date +"%g%m%d.%H%M%S")

to your ~/.profile, and remember compile with gcc $CPPFLAGS ...

Long answer:

I know this question is older, but I have a small contribution to make. Best practice is always automatize what otherwise can became a source of error (or oblivion).

I was used to a function that created the version number for me. But I prefer this function to return a float. My version number can be printed by: printf("%13.6f\n", version()); which issues something like: 150710.150411 (being Year (2 digits) month day DOT hour minute seconds).

But, well, the question is yours. If you prefer "major.minor.date.time", it will have to be a string. (Trust me, double is better. If you insist in a major, you can still use double if you set the major and let the decimals to be date+time, like: major.datetime = 1.150710150411

Lets get to business. The example bellow will work if you compile as usual, forgetting to set it, or use -DVERSION to set the version directly from shell, but better of all, I recommend the third option: use a makefile.

Three forms of compiling and the results:

Using make:

beco> make program.x
gcc -Wall -Wextra -g -O0 -ansi -pedantic-errors -c -DVERSION="\"3.33.20150710.045829\"" program.c -o program.o
gcc  program.o -o program.x

Running:

__DATE__: 'Jul 10 2015'
__TIME__: '04:58:29'
VERSION: '3.33.20150710.045829'

Using -DVERSION:

beco> gcc program.c -o program.x -Wall -Wextra -g -O0 -ansi -pedantic-errors -DVERSION=\"2.22.$(date +"%Y%m%d.%H%M%S")\"

Running:

__DATE__: 'Jul 10 2015'
__TIME__: '04:58:37'
VERSION: '2.22.20150710.045837'

Using the build-in function:

beco> gcc program.c -o program.x -Wall -Wextra -g -O0 -ansi -pedantic-errors

Running:

__DATE__: 'Jul 10 2015'
__TIME__: '04:58:43'
VERSION(): '1.11.20150710.045843'

Please note that the string is limited by MAJOR<=9999 and MINOR<=9999. Of course, I set this high value that will hopefully never overflow. But using double is still better (plus, it's completely automatic, no need to set MAJOR and MINOR by hand).

Now, the program above is a bit too much. Better is to remove the function completely, and guarantee that the macro VERSION is defined, either by -DVERSION directly into GCC command line (or an alias that automatically add it so you can't forget), or the recommended solution, to include this process into a makefile.

Here it is the makefile I use:

MakeFile source:

  1   MAJOR = 3
  2   MINOR = 33
  3   BUILD = $(shell date +"%Y%m%d.%H%M%S")
  4   VERSION = "\"$(MAJOR).$(MINOR).$(BUILD)\""
  5   CC = gcc
  6   CFLAGS = -Wall -Wextra -g -O0 -ansi -pedantic-errors
  7   CPPFLAGS = -DVERSION=$(VERSION)
  8   LDLIBS =
  9   
 10    %.x : %.c
 11          $(CC) $(CFLAGS) $(CPPFLAGS) $(LDLIBS) $^ -o $@

A better version with DOUBLE

Now that I presented you "your" preferred solution, here it is my solution:

Compile with (a) makefile or (b) gcc directly:

(a) MakeFile:

   VERSION = $(shell date +"%g%m%d.%H%M%S")
   CC = gcc
   CFLAGS = -Wall -Wextra -g -O0 -ansi -pedantic-errors 
   CPPFLAGS = -DVERSION=$(VERSION)
   LDLIBS =
   %.x : %.c
         $(CC) $(CFLAGS) $(CPPFLAGS) $(LDLIBS) $^ -o $@

(b) Or a simple bash command:

 $ gcc program.c -o program.x -Wall -Wextra -g -O0 -ansi -pedantic-errors -DVERSION=$(date +"%g%m%d.%H%M%S")

Source code (double version):

#ifndef VERSION
  #define VERSION version()
#endif

double version(void);

int main(void)
{
  printf("VERSION%s: '%13.6f'\n", (FUNC_VERSION?"()":""), VERSION);
  return 0;
}

double version(void)
{
  const char data[]=__DATE__;
  const char tempo[]=__TIME__;
  const char nomes[] = "JanFebMarAprMayJunJulAugSepOctNovDec";
  char omes[4];
  int ano, mes, dia, hora, min, seg;
  char sversion[]="130910.001339";
  double fv;

  if(strlen(data)!=11||strlen(tempo)!=8)
    return -1.0;

  sscanf(data, "%s %d %d", omes, &dia, &ano);
  sscanf(tempo, "%d:%d:%d", &hora, &min, &seg);
  mes=(strstr(nomes, omes)-nomes)/3+1;
  sprintf(sversion,"%04d%02d%02d.%02d%02d%02d", ano, mes, dia, hora, min, seg);
  fv=atof(sversion);

  return fv;
}

Note: this double function is there only in case you forget to define macro VERSION. If you use a makefile or set an alias gcc gcc -DVERSION=$(date +"%g%m%d.%H%M%S"), you can safely delete this function completely.

Well, that's it. A very neat and easy way to setup your version control and never worry about it again!

CSS selector:

Use a CSS selector of img[src='images/toolbar/b_edit.gif']

This says select element(s) with img tag with attribute src having value of 'images/toolbar/b_edit.gif'

CSS query:

VBA:

You can apply the selector with the .querySelector method of document.

IE.document.querySelector("img[src='images/toolbar/b_edit.gif']").Click

Use this code

            Intent intent = new Intent(getApplicationContext(), SomeActvity.class);
            PendingIntent pIntent = PendingIntent.getActivity(getApplicationContext(),
                    (int) System.currentTimeMillis(), intent, 0);

            NotificationCompat.Builder mBuilder =
                    new NotificationCompat.Builder(getApplicationContext())

You will need to change the configure port of either Apache or Nginx. After you do this you will need to restart the reconfigured servers, using the 'service' command you used.

Apache

Edit

sudo subl /etc/apache2/ports.conf 

and change the 80 on the following line to something different :

Listen 80

If you just change the port or add more ports here, you will likely also have to change the VirtualHost statement in

sudo subl /etc/apache2/sites-enabled/000-default.conf

and change the 80 on the following line to something different :

<VirtualHost *:80>

then restart by :

sudo service apache2 restart

Nginx

Edit

/etc/nginx/sites-enabled/default

and change the 80 on the following line :

listen 80;

then restart by :

sudo service nginx restart

Your regex pattern needs to be in delimiters:

$numpattern="/^([0-9]+)$/";

Most recent solution:

HTML

<div class="parent">
    <img src="image.jpg" height="600" width="600"/>
</div>

CSS

.parent {
    width: 200px;
    height: 200px;
    overflow: hidden;
    /* Magic */
    display: flex;
    align-items: center; /* vertical */
    justify-content: center; /* horizontal */
}

you can check the type. s3 has a special application/x-directory

bucket.objects({:delimiter=>"/", :prefix=>"f1/"}).each { |obj| p obj.object.content_type }

You can find a whole bunch of Linq examples in visual studio. Just select Help -> Samples, and then unzip the Linq samples.

Open the linq samples solution and open the LinqSamples.cs of the SampleQueries project.

The answer you are looking for is in method Linq14:

int[] numbersA = { 0, 2, 4, 5, 6, 8, 9 };
int[] numbersB = { 1, 3, 5, 7, 8 };

var pairs =
   from a in numbersA
   from b in numbersB
   where a < b
   select new {a, b};

Going back to absolute basics here. The answers on this page and a little googling have brought me to the following resolution to my issue. Steps to restart the apache service with Xampp installed:-

1. Click the start button and type CMD (if on Windows Vista or later and Apache is installed as a service make sure this is an elevated command prompt)
2. In the command window that appears type cd C:\xampp\apache\bin (the default installation path for Xampp)
3. Then type httpd -k restart

I hope that this is of use to others just starting out with running a local Apache server.

If you're using a linux server for your application then it is necessary to use lowercase file name and class name to avoid this issue.

Ex.

Filename: csvsample.php

class csvsample {

}

If you don't need to change something onMeasure - there's absolutely no need for you to override it.

Devunwired code (the selected and most voted answer here) is almost identical to what the SDK implementation already does for you (and I checked - it had done that since 2009).

You can check the onMeasure method here :

protected void onMeasure(int widthMeasureSpec, int heightMeasureSpec) {
    setMeasuredDimension(getDefaultSize(getSuggestedMinimumWidth(), widthMeasureSpec),
            getDefaultSize(getSuggestedMinimumHeight(), heightMeasureSpec));
}

public static int getDefaultSize(int size, int measureSpec) {
    int result = size;
    int specMode = MeasureSpec.getMode(measureSpec);
    int specSize = MeasureSpec.getSize(measureSpec);

    switch (specMode) {
    case MeasureSpec.UNSPECIFIED:
        result = size;
        break;
    case MeasureSpec.AT_MOST:
    case MeasureSpec.EXACTLY:
        result = specSize;
        break;
    }
    return result;
}

Overriding SDK code to be replaced with the exact same code makes no sense.

This official doc's piece that claims "the default onMeasure() will always set a size of 100x100" - is wrong.

you can find it by running the following command

mysql --help

it will give you the mysql installed directory and all commands for mysql.

For that, you could use a Dictionary where the int is the key.

new Dictionary<int, string>();

If you really want to use a list, it could be a List<Tuple<int,string>>() but, Tuple class is readonly, so you have to recreate the instance to modifie it.

I think you are confusing objects and classes. A class inside a class looks like this:

class Foo(object):
    class Bar(object):
        pass

>>> foo = Foo()
>>> bar = Foo.Bar()

But it doesn't look to me like that's what you want. Perhaps you are after a simple containment hierarchy:

class Player(object):
    def __init__(self, ... airplanes ...) # airplanes is a list of Airplane objects
        ...
        self.airplanes = airplanes
        ...

class Airplane(object):
    def __init__(self, ... flights ...) # flights is a list of Flight objects
        ...
        self.flights = flights
        ...

class Flight(object):
    def __init__(self, ... duration ...)
        ...
        self.duration = duration
        ...

Then you can build and use the objects thus:

player = Player(...[
    Airplane(... [
        Flight(...duration=10...),
        Flight(...duration=15...),
        ] ... ),
    Airplane(...[
        Flight(...duration=20...),
        Flight(...duration=11...),
        Flight(...duration=25...),
        ]...),
    ])

player.airplanes[5].flights[6].duration = 5

I think a more canonical way to do this is via:

command --feature

and

command --no-feature

argparse supports this version nicely:

parser.add_argument('--feature', dest='feature', action='store_true')
parser.add_argument('--no-feature', dest='feature', action='store_false')
parser.set_defaults(feature=True)

Of course, if you really want the --arg <True|False> version, you could pass ast.literal_eval as the "type", or a user defined function ...

def t_or_f(arg):
    ua = str(arg).upper()
    if 'TRUE'.startswith(ua):
       return True
    elif 'FALSE'.startswith(ua):
       return False
    else:
       pass  #error condition maybe?

If you want be sure you need to check both

SomeProperty == null || SomeProperty == Guid.Empty

Because it can be null 'Nullable' and it can be an empty GUID something like this {00000000-0000-0000-0000-000000000000}

import java.util.AbstractSet;
import java.util.Iterator;
import java.util.Set;
import java.util.concurrent.ConcurrentHashMap;
import java.util.concurrent.ConcurrentMap;


public class ConcurrentHashSet<E> extends AbstractSet<E> implements Set<E>{
   private final ConcurrentMap<E, Object> theMap;

   private static final Object dummy = new Object();

   public ConcurrentHashSet(){
      theMap = new ConcurrentHashMap<E, Object>();
   }

   @Override
   public int size() {
      return theMap.size();
   }

   @Override
   public Iterator<E> iterator(){
      return theMap.keySet().iterator();
   }

   @Override
   public boolean isEmpty(){
      return theMap.isEmpty();
   }

   @Override
   public boolean add(final E o){
      return theMap.put(o, ConcurrentHashSet.dummy) == null;
   }

   @Override
   public boolean contains(final Object o){
      return theMap.containsKey(o);
   }

   @Override
   public void clear(){
      theMap.clear();
   }

   @Override
   public boolean remove(final Object o){
      return theMap.remove(o) == ConcurrentHashSet.dummy;
   }

   public boolean addIfAbsent(final E o){
      Object obj = theMap.putIfAbsent(o, ConcurrentHashSet.dummy);
      return obj == null;
   }
}

Recently, I had the same problem within .NET 3.5 (no dynamic available). Here is how I solved:

// pass anonymous object as argument
var args = new { Title = "Find", Type = typeof(FindCondition) };

using (frmFind f = new frmFind(args)) 
{
...
...
}

Adapted from somewhere on stackoverflow:

// Use a custom cast extension
public static T CastTo<T>(this Object x, T targetType)
{
   return (T)x;
}

Now get back the object via cast:

public partial class frmFind: Form
{
    public frmFind(object arguments)
    {

        InitializeComponent();

        var args = arguments.CastTo(new { Title = "", Type = typeof(Nullable) });

        this.Text = args.Title;

        ...
    }
    ...
}

Although both answers are technically correct, I want to introduce a different syntax choice for this answer. This imho makes it easier to read what's going on with injection, differentiate between etc.

File One

// Create the module that deals with controllers
angular.module('myApp.controllers', []);

File Two

// Here we get the module we created in file one
angular.module('myApp.controllers')

// We are adding a function called Ctrl1
// to the module we got in the line above
.controller('Ctrl1', Ctrl1);

// Inject my dependencies
Ctrl1.$inject = ['$scope', '$http'];

// Now create our controller function with all necessary logic
function Ctrl1($scope, $http) {
  // Logic here
}

File Three

// Here we get the module we created in file one
angular.module('myApp.controllers')

// We are adding a function called Ctrl2
// to the module we got in the line above
.controller('Ctrl2', Ctrl2);

// Inject my dependencies
Ctrl2.$inject = ['$scope', '$http'];

// Now create our controller function with all necessary logic
function Ctrl2($scope, $http) {
  // Logic here
}

SELECT SUBSTRING('aaaaa$bbbbb$ccccc',instr('aaaaa$bbbbb$ccccc','$',1,1)+1, instr('aaaaa$bbbbb$ccccc','$',1,2)-1) -instr('aaaaa$bbbbb$ccccc','$',1,1)) as My_String

Just experienced this in a method that executes a linq query.

public async Task<Foo> GetSomething()
{
    return await (from foo in Foos
                  select foo).FirstOrDefault();
}

Needed to use .FirstOrDefaultAsync() instead. N00b mistake.

Don't write if statements without a corresponding else. Once you add the else to your fragment you'll see that your true and false are in fact the last expressions of the function.

def balanceMain(elem: List[Char]): Boolean =
  {
    if (elem.isEmpty)
      if (count == 0)
        true
      else
        false
    else
      if (elem.head == '(')
        balanceMain(elem.tail, open, count + 1)
      else....

mandatory parts:

tbody {
    overflow-y: scroll;  (could be: 'overflow: scroll' for the two axes)
    display: block;
    with: xxx (a number or 100%)
}

thead {
    display: inline-block;
}

To build and install modern Git on CentOS 6:

yum install -y curl-devel expat-devel gettext-devel openssl-devel zlib-devel gcc perl-ExtUtils-MakeMaker
export GIT_VERSION=2.6.4
mkdir /root/git
cd /root/git
wget "https://www.kernel.org/pub/software/scm/git/git-${GIT_VERSION}.tar.gz"
tar xvzf "git-${GIT_VERSION}.tar.gz"
cd git-${GIT_VERSION}
make prefix=/usr/local all
make prefix=/usr/local install
yum remove -y git
git --version # should be GIT_VERSION

You can Use KeyPress instead of KeyUp or KeyDown its more efficient and here's how to handle

private void textBox1_KeyPress(object sender, KeyPressEventArgs e)
    {
        if (e.KeyChar == (char)Keys.Enter)
        {
            e.Handled = true;
            button1.PerformClick();
        }
    }

hope it works

The issue was resolved as I was having a JDK pointing to 1.7 and JRE pointing to 1.8. Check in the command prompt by typing

java -version

and

javac -version

Both should be same.  

Generics can't use primitive types in the form of keywords.

Use

public HashMap<Character, Integer> buildMap(String letters)
{
    HashMap<Character, Integer> checkSum = new HashMap<Character, Integer>();

    for ( int i = 0; i < letters.length(); ++i )
    {
        checkSum.put(letters.charAt(i), primes[i]);
    }

    return checkSum;
}

Updated: With Java 7 and later, you can use the diamond operator.

HashMap<Character, Integer> checkSum = new HashMap<>();

You can call System.exit(); to get out of all the acivities.

    submit=(Button)findViewById(R.id.submit);

            submit.setOnClickListener(new OnClickListener() {

                @Override
                public void onClick(View arg0) {
android.os.Process.killProcess(android.os.Process.myPid());
                    System.exit(1);

                }
            });

The logic is not flawed. The statement

if x is y then x==y is also True

should never be read to mean

if x==y then x is y

It is a logical error on the part of the reader to assume that the converse of a logic statement is true. See http://en.wikipedia.org/wiki/Converse_(logic)

In 2012 OData underwent standardization, so I'll just add an update here..

First the definitions:

REST - is an architecture of how to send messages over HTTP.

OData V4- is a specific implementation of REST, really defines the content of the messages in different formats (currently I think is AtomPub and JSON). ODataV4 follows rest principles.

For example, asp.net people will mostly use WebApi controller to serialize/deserialize objects into JSON and have javascript do something with it. The point of Odata is being able to query directly from the URL with out-of-the-box options.

Have you tried this ?

<input type="submit" style="visibility: hidden;" />

Since most browsers understand visibility:hidden and it doesn't really work like display:none, I'm guessing that it should be fine, though. Haven't really tested it myself, so CMIIW.

If you'd like to gather more information on the error and if the error occurs in the first few iterations, I suggest you run the experiment in CPU-only mode (no GPUs). The error message will be much more specific.

Source: https://github.com/tensorflow/tensor2tensor/issues/574

You override $today in the if statement.

if($dd<10){$dd='0'+dd} if($mm<10){$mm='0'+$mm} $today = $dd+'/'+$mm+'/'+$yyyy;

It is then not a Date() object anymore - hence the error.

To get rid of the first column of NAs, you can do it with negative indexing (which removes indices from the R data set). For example:

output = matrix(1:6, 2, 3) # gives you a 2 x 3 matrix filled with the numbers 1 to 6

# output = 
#           [,1] [,2] [,3]
#     [1,]    1    3    5
#     [2,]    2    4    6

output = output[,-1] # this removes column 1 for all rows

# output = 
#           [,1] [,2]
#     [1,]    3    5
#     [2,]    4    6

So you can just add output = output[,-1]after the for loop in your original code.

I've got same error when my interface (with all pure virtual functions) needed one more function and I forgot to "null" it.

I had

class ICommProvider { public: /** * @brief If connection is established, it sends the message into the server. * @param[in] msg - message to be send * @return 0 if success, error otherwise */ virtual int vaSend(const std::string &msg) = 0; /** * @brief If connection is established, it is waiting will server response back. * @param[out] msg is the message received from server * @return 0 if success, error otherwise */ virtual int vaReceive(std::string &msg) = 0; virtual int vaSendRaw(const char *buff, int bufflen) = 0; virtual int vaReceiveRaw(char *buff, int bufflen) = 0; /** * @bief Closes current connection (if needed) after serving * @return 0 if success, error otherwise */ virtual int vaClose(); };

Last vaClose is not virtual so compiled did not know where to get implementation for it and thereby got confused. my message was:

...TCPClient.o:(.rodata+0x38): undefined reference to `typeinfo for ICommProvider'

Simple change from

virtual int vaClose();

to

virtual int vaClose() = 0;

fixed the problem. hope it helps

I'm sure you have your reasons, but just in case... you should also consider using a "merge" query instead:

begin
    merge into some_table st
    using (select 'some' name, 'values' value from dual) v
    on (st.name=v.name)
    when matched then update set st.value=v.value
    when not matched then insert (name, value) values (v.name, v.value);
end;

(modified the above to be in the begin/end block; obviously you can run it independantly of the procedure too).

I faced the same issue when,

I had created new angular project using old angular-cli version (1.4.7) I then updated angular-cli using below commands (DO NOT DO THE BELOW TO UPDATE CLI)

• npm uninstall -g @angular/cli
• npm cache clean --force
• npm install -g @angular/cli@latest

Now when I tried ng serve, i was getting same error like you

Angular Cli Error: The serve command requires to be run in an Angular project, but a project definition could not be found

DO BELOW TO UPDATE CLI

ng update @angular/cli --migrate-only --from=1.4.7

Implementation is up to compiler developers.

If your question is "what will happen with such declaration" - compiler will set first array element to the value you've provided (0) and all others will be set to zero because it is a default value for omitted array elements.

I know this question is a couple years old, but I am surprised to find that no one suggested:

   text-align: center;

this is a more universal property than justify-content, and is definitely not unique to grid, but I find that when dealing with text, which is what this question specifically asks about, that it aligns text to the center with-out affecting the space between grid items, or the vertical centering. It centers text horizontally where its stands on its vertical axis. I also find it to remove a layer of complexity that justify-content and align-items adds. justify-content and align-items affects the entire grid item or items, text-align centers the text without affecting the container it is in. Hope this helps.

childClass::customMethod() has different arguments, or a different access level (public/private/protected) than parentClass::customMethod().

Set the CheckBox as focusable="false" in your XML layout. Otherwise it will steal click events from the list view.

Of course, if you do this, you need to manually handle marking the CheckBox as checked/unchecked if the list item is clicked instead of the CheckBox, but you probably want that anyway.

if user doesn't have any qr reader, what will happen to the application? if it crashes, may i ask user to download for example QrDroid and after that use it?

Interestingly, Google now introduced Mobile Vision APIs, they are integrated in play services itself.

In your Gradle file just add:

compile 'com.google.android.gms:play-services-vision:11.4.0'

Taken from this QR code tutorial.

UPDATE 2020:

Now QR code scanning is also a part of ML Kit, so you can bundle the model inside the app and use it by integrating the following gradle dependency:

dependencies {
  // ...
  // Use this dependency to bundle the model with your app
  implementation 'com.google.mlkit:barcode-scanning:16.0.3'
}

Or you can use the following gradle dependency to dynamically download the models from Google Play Services:

dependencies {
  // ...
  // Use this dependency to use the dynamically downloaded model in Google Play Services
  implementation 'com.google.android.gms:play-services-mlkit-barcode-scanning:16.1.2'
}

Taken from this link.

If the main problem is the loss of precision when converting from a float to a string, one possible way to go is to convert the floats to the decimalS: http://docs.python.org/library/decimal.html.

In python 2.7 and higher you can directly convert a float to a decimal object.

Based on Jon Skeet answer i've made a class that permits to do it easily at work:

import com.google.common.collect.ImmutableMap;
import com.google.common.collect.Maps;

import java.util.EnumSet;
import java.util.HashSet;
import java.util.Map;
import java.util.Set;

/**

 * This permits to easily implement a failsafe implementation of the enums's valueOf
 * Better use it inside the enum so that only one of this object instance exist for each enum...
 * (a cache could solve this if needed)
 * </p>
 *
 * <p>
 * Basic usage exemple on an enum class called MyEnum:
 *
 *   private static final FailSafeValueOf<MyEnum> FAIL_SAFE = FailSafeValueOf.create(MyEnum.class);
 *   public static MyEnum failSafeValueOf(String enumName) {
 *       return FAIL_SAFE.valueOf(enumName);
 *   }
 *
 * </p>
 *
 * <p>
 * You can also use it outside of the enum this way:
 *   FailSafeValueOf.create(MyEnum.class).valueOf("EnumName");
 * </p>
 *
 * @author Sebastien Lorber <i>([email protected])</i>
 */
public class FailSafeValueOf<T extends Enum<T>> {

    private final Map<String,T> nameToEnumMap;

    private FailSafeValueOf(Class<T> enumClass) {
        Map<String,T> map = Maps.newHashMap();
        for ( T value : EnumSet.allOf(enumClass)) {
            map.put( value.name() , value);
        }
        nameToEnumMap = ImmutableMap.copyOf(map);
    }

    /**
     * Returns the value of the given enum element

    public T valueOf(String enumName) {

    }

    public static <U extends Enum<U>> FailSafeValueOf<U> create(Class<U> enumClass) {
        return new FailSafeValueOf<U>(enumClass);
    }

}

And the unit test:

import org.testng.annotations.Test;

import static org.testng.Assert.*;


/**

        public static MyEnum failSafeValueOf(String enumName) {
            return FAIL_SAFE.valueOf(enumName);
        }
    }

    @Test
    public void testInEnum() {
        assertNotNull( MyEnum.failSafeValueOf("TOTO") );
        assertNotNull( MyEnum.failSafeValueOf("TATA") );
        assertNull( MyEnum.failSafeValueOf("TITI") );
    }

    @Test
    public void testInApp() {

        assertNull( FailSafeValueOf.create(MyEnum.class).valueOf("TITI") );
    }

}

Notice that i used Guava to make an ImmutableMap but actually you could use a normal map i think since the map is never returned...

I suggest Freewall. It is a cross-browser and responsive jQuery plugin to help you create many types of grid layouts: flexible layouts, images layouts, nested grid layouts, metro style layouts, pinterest like layouts ... with nice CSS3 animation effects and call back events. Freewall is all-in-one solution for creating dynamic grid layouts for desktop, mobile, and tablet.

How about this one?

SELECT TO_CHAR(ASOFDATE, 'YYYY') FROM PSASOFDATE

POSIX defines a function: wait(NULL);. It's the shorthand for waitpid(-1, NULL, 0);, which will suspends the execution of the calling process until any one child process exits. Here, 1st argument of waitpid indicates wait for any child process to end.

In your case, have the parent call it from within your else branch.

Method 1: grep (may careful while value is expected to be a regex).

Try to avoid using grep, if looking at resources.

if ( grep( /^$value$/, @badparams ) ) {
  print "found";
}

Method 2: Linear Search

for (@badparams) {
    if ($_ eq $value) {
       print "found";
       last;
    }
}

Method 3: Use a hash

my %hash = map {$_ => 1} @badparams;
print "found" if (exists $hash{$value});

Method 4: smartmatch

(added in Perl 5.10, marked is experimental in Perl 5.18).

use experimental 'smartmatch';  # for perl 5.18
print "found" if ($value ~~ @badparams);

Method 5: Use the module List::MoreUtils

use List::MoreUtils qw(any);
@badparams = (1,2,3);
$value = 1;
print "found" if any {$_ == $value} @badparams;

While currently not possible with CSS, there is a proposal to enable this functionality called Cascading Attribute Sheets.

You could use \r\n, or System.Environment.NewLine.

One of the things that you might want to try out is starting eclipse with the -clean option. If you have chosen to have eclipse use the same workspace every time then there is nothing else you need to do after that. With that option in place the workspace should be cleaned out.

However, if you don't have a default workspace chosen, when opening up eclipse you will be prompted to choose the workspace. At this point, choose the workspace you want cleaned up.

See "How to run eclipse in clean mode" and "Keeping Eclipse running clean" for more details.

You could use String.Split method.

class ExampleClass
{
    public ExampleClass()
    {
        string exampleString = "there is a cat";
        // Split string on spaces. This will separate all the words in a string
        string[] words = exampleString.Split(' ');
        foreach (string word in words)
        {
            Console.WriteLine(word);
            // there
            // is
            // a
            // cat
        }
    }
}

For more information see Sam Allen's article about splitting strings in c# (Performance, Regex)

Sort of similar to what mattbtay said, but a few changes. needed html:true.
Put this script on bottom of the page towards close body tag.

<script type="text/javascript">
 $(document).ready(function() {
  $("[rel=drevil]").popover({
      placement : 'bottom', //placement of the popover. also can use top, bottom, left or right
      title : '<div style="text-align:center; color:red; text-decoration:underline; font-size:14px;"> Muah ha ha</div>', //this is the top title bar of the popover. add some basic css
      html: 'true', //needed to show html of course
      content : '<div id="popOverBox"><img src="http://www.hd-report.com/wp-content/uploads/2008/08/mr-evil.jpg" width="251" height="201" /></div>' //this is the content of the html box. add the image here or anything you want really.
});
});
</script>

Then HTML is:

<a href="#" rel="drevil">mischief</a>

For errors like this you should involve oracle support. Unfortunately you do not mention what oracle release you are using. The error can be related to optimizer bind peeking. Depending on the oracle version different workarounds apply.

You have two ways to address this:

• upgrade to 11.2
• set oracle parameter _optim_peek_user_binds = false

Of course underscore parameters should only be set if advised by oracle support

I think you may need to stringify the data using JSON.stringify.

 var data = JSON.stringify({ 
                 'StrContactDetails': Details,
                 'IsPrimary':true
               });

$.ajax({
        type: "POST",
        url: @url.Action("Dhp","SaveEmergencyContact"),
        data: data,
        success: function(){},
        contentType: 'application/json'
    });

So the controller method would look like,

public ActionResult SaveEmergencyContact(string  StrContactDetails, bool IsPrimary)

Using the SVG from @ArnoTenkink as an data url combined with the accepted answer, this gives us the perfect solution for retina displays.

First create the database and table, manually adding the columns. In which column to be primary key. You should right click this column and set primary key and set the seed value of the primary key.

To define the preference in Fragment: SharedPreferences pref = getActivity().getSharedPreferences("CargaDatosCR",Context.MODE_PRIVATE); editor.putString("credi_credito",cre); editor.commit();

To call another activity or fragment the preference data: SharedPreferences pref = getActivity().getSharedPreferences("CargaDatosCR", Context.MODE_PRIVATE); credit=pref.getString("credi_credito",""); if(credit.isNotEmpty)...

128 characters. This is the max length of the sysname datatype (nvarchar(128)).

Since you now specified you want to add to it, what you want isn't a simple IEnumerable<T> but at least an ICollection<T>. I recommend simply using a List<T> like this:

List<object> myList=new List<object>();
myList.Add(1);
myList.Add(2);
myList.Add(3);

You can use myList everywhere an IEnumerable<object> is expected, since List<object> implements IEnumerable<object>.

(old answer before clarification)

You can't create an instance of IEnumerable<T> since it's a normal interface(It's sometimes possible to specify a default implementation, but that's usually used only with COM).

So what you really want is instantiate a class that implements the interface IEnumerable<T>. The behavior varies depending on which class you choose.

For an empty sequence use:

IEnumerable<object> e0=Enumerable.Empty<object>();

For an non empty enumerable you can use some collection that implements IEnumerable<T>. Common choices are the array T[], List<T> or if you want immutability ReadOnlyCollection<T>.

IEnumerable<object> e1=new object[]{1,2,3};
IEnumerable<object> e2=new List<object>(){1,2,3};
IEnumerable<object> e3=new ReadOnlyCollection(new object[]{1,2,3});

Another common way to implement IEnumerable<T> is the iterator feature introduced in C# 3:

IEnumerable<object> MyIterator()
{
  yield return 1;
  yield return 2;
  yield return 3;
}

IEnumerable<object> e4=MyIterator();

Goals are executed in phases which help determine the order goals get executed in. The best understanding of this is to look at the default Maven lifecycle bindings which shows which goals get run in which phases by default. The compile phase goals will always be executed before the test phase goals, which will always be executed before the package phase goals and so on.

Part of the confusion is exacerbated by the fact that when you execute Maven you can specify a goal or a phase. If you specify a phase then Maven will run all phases up to the phase you specified in order (e.g. if you specify package it will first run through the compile phase and then the test phase and finally the package phase) and for each phase it will run all goals attached to that phase.

When you create a plugin execution in your Maven build file and you only specify the goal then it will bind that goal to a given default phase. For example, the jaxb:xjc goal binds by default to the generate-resources phase. However, when you specify the execution you can also explicitly specify the phase for that goal as well.

If you specify a goal when you execute Maven then it will run that goal and only that goal. In other words, if you specify the jar:jar goal it will only run the jar:jar goal to package your code into a jar. If you have not previously run the compile goal or prepared your compiled code in some other way this may very likely fail.

If .toggle is not working I would do the next:

var flag = false;
$('#click_advance').click(function(){
    if( flag == false){
       $('#display_advance').show('1000');
         // Add more code
       flag = true;
    }
    else{
       $('#display_advance').hide('1000');
       // Add more code
       flag = false;
    }
}

It's a little bit more code, but it works

You cant do it on shared hosting , Add ticket to support of hosting for same ( otherwise you can look for dedicated server where you can manage anything )

For me, I was having the same issue, the issue was that there was an unused RecyclerView in xml with view gone but I am not binding it to any adapter in Activity, hence the issue. It was solved as soon as I removed such unused recycler views in xml

i.e - I removed this view as this was not called in code or any adapter has been set

<android.support.v7.widget.RecyclerView
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:id="@+id/rv_profileview_allactivities"
        android:visibility="gone" />

Just leaving the way using Microsoft.AspNet.WebApi.Client here.

Example:

var client = HttpClientFactory.Create();
var result = await client.PostAsync<ExampleClass>("http://www.sample.com/write", new ExampleClass(), new JsonMediaTypeFormatter());

the wmic bios get serialnumber command call the Win32_BIOS wmi class and get the value of the SerialNumber property, which retrieves the serial number of the BIOS Chip of your system.

read with IFS are perfect for this:

$ IFS=- read var1 var2 <<< ABCDE-123456
$ echo "$var1"
ABCDE
$ echo "$var2"
123456

Edit:

Here is how you can read each individual character into array elements:

$ read -a foo <<<"$(echo "ABCDE-123456" | sed 's/./& /g')"

Dump the array:

$ declare -p foo
declare -a foo='([0]="A" [1]="B" [2]="C" [3]="D" [4]="E" [5]="-" [6]="1" [7]="2" [8]="3" [9]="4" [10]="5" [11]="6")'

If there are spaces in the string:

$ IFS=$'\v' read -a foo <<<"$(echo "ABCDE 123456" | sed 's/./&\v/g')"
$ declare -p foo
declare -a foo='([0]="A" [1]="B" [2]="C" [3]="D" [4]="E" [5]=" " [6]="1" [7]="2" [8]="3" [9]="4" [10]="5" [11]="6")'

-xms is the start memory (at the VM start), -xmx is the maximum memory for the VM

• eclipse.ini : the memory for the VM running eclipse
• jre setting : the memory for java programs run from eclipse
• catalina.sh : the memory for your tomcat server

mysqli_error()

As in:

$sql = "Your SQL statement here";
$result = mysqli_query($conn, $sql) or trigger_error("Query Failed! SQL: $sql - Error: ".mysqli_error($conn), E_USER_ERROR);

Trigger error is better than die because you can use it for development AND production, it's the permanent solution.

It is useful if you are building a kernel - where do you place the kernel code you read from disk or the pagetable? You need to know where to jump to.

Or in other, very rare circumstances such as when you have loads of allocated room and want to place a few structures behind each other. They can be packed this way without the need for the offsetof() operator. There are other tricks for that too, though.

I also believe some STL implementations make use of placement new, like std::vector. They allocate room for 2^n elements that way and don't need to always realloc.

MouseInfo.getPointerInfo().getLocation() might be helpful. It returns a Point object corresponding to current mouse position.

Your algorithm is correct. But we can do optimization as follows: While reversing, You may try keeping another variable to reduce backward counter since computing of array.length-(i+1) may take time! And also move declaration of temp outside so that everytime it needs not to be allocated

double temp;

for(int i=0,j=array.length-1; i < (array.length/2); i++, j--) {

     // swap the elements
     temp = array[i];
     array[i] = array[j];
     array[j] = temp;
}

Here is some Java code that worked for me:

boolean liesOnSegment(Coordinate a, Coordinate b, Coordinate c) {
        
    double dotProduct = (c.x - a.x) * (c.x - b.x) + (c.y - a.y) * (c.y - b.y);
    return (dotProduct < 0);
}

I've found the same problem before, hope this solution can help you. first, add a custom attribute to your checkboxes:

<input type="checkbox" id="ans" value="1" data-unchecked="0" />

write a jQuery extension to get value:

$.fn.realVal = function(){
    var $obj = $(this);
    var val = $obj.val();
    var type = $obj.attr('type');
    if (type && type==='checkbox') {
        var un_val = $obj.attr('data-unchecked');
        if (typeof un_val==='undefined') un_val = '';
        return $obj.prop('checked') ? val : un_val;
    } else {
        return val;
    }
};

use code to get check-box value:

$('#ans').realVal();

you can test here

nib is fine. If in doubt, refer to the Python style guide.

From PEP 8:

Package and Module Names Modules should have short, all-lowercase names. Underscores can be used in the module name if it improves readability. Python packages should also have short, all-lowercase names, although the use of underscores is discouraged.

Since module names are mapped to file names, and some file systems are case insensitive and truncate long names, it is important that module names be chosen to be fairly short -- this won't be a problem on Unix, but it may be a problem when the code is transported to older Mac or Windows versions, or DOS.

When an extension module written in C or C++ has an accompanying Python module that provides a higher level (e.g. more object oriented) interface, the C/C++ module has a leading underscore (e.g. _socket).

Hi,

Well, I have tried the methods mentioned above! it's working yes, but not exactly the way I wanted. I wanted to redirect the default page extension to the main domain with our further action.

Here how I do that...

# Accesible Index Page
<IfModule dir_module>
 DirectoryIndex index.php index.html
 RewriteCond %{THE_REQUEST} ^[A-Z]{3,9}\ /index\.(html|htm|php|php3|php5|shtml|phtml) [NC]
 RewriteRule ^index\.html|htm|php|php3|php5|shtml|phtml$ / [R=301,L]
</IfModule>

The above code simply captures any index.* and redirect it to the main domain.

Thank you

I have this issue too. I suspect there is an issue with DigitalOcean’s nameservers, so this will likely affect a lot of other people too. Here’s what I’ve done to temporarily get around it - but someone else might be able to advise on a better long-term fix:

1. Make sure your DNS Resolver config file is writable:

   sudo chmod o+r /etc/resolv.conf

2. Temporarily change your DNS to use Google’s nameservers instead of DigitalOcean’s:

   sudo nano /etc/resolv.conf

Change the IP address in the file to: 8.8.8.8

Press CTRL + X to save the file.

This is only a temporary fix as this file is automatically written/updated by the server, however, I’ve not yet worked out what writes to it so that I can update it permanently.

I know this is an old question, but I stumbled across it when I was having a similar issue, and just wanted to share how I ended achieving the results you requested so future people can pick what works best for their situation.

First, I utilize the onsubmit event in the form, and pass this to the function to make it easier to deal with this particular form.

<form action="/system/wpacert" onsubmit="return closeSelf(this);" method="post" enctype="multipart/form-data"  name="certform">
    <div>Certificate 1: <input type="file" name="cert1"/></div>
    <div>Certificate 2: <input type="file" name="cert2"/></div>
    <div>Certificate 3: <input type="file" name="cert3"/></div>

    <div><input type="submit" value="Upload"/></div>
</form>

In our function, we'll submit the form data, and then we'll close the window. This will allow it to submit the data, and once it's done, then it'll close the window and return you to your original window.

<script type="text/javascript">
  function closeSelf (f) {
     f.submit();
     window.close();
  }
</script>

Hope this helps someone out. Enjoy!

Option 2: This option will let you submit via AJAX, and if it's successful, it'll close the window. This prevents windows from closing prior to the data being submitted. Credits to http://jquery.malsup.com/form/ for their work on the jQuery Form Plugin

First, remove your onsubmit/onclick events from the form/submit button. Place an ID on the form so AJAX can find it.

<form action="/system/wpacert" method="post" enctype="multipart/form-data"  id="certform">
    <div>Certificate 1: <input type="file" name="cert1"/></div>
    <div>Certificate 2: <input type="file" name="cert2"/></div>
    <div>Certificate 3: <input type="file" name="cert3"/></div>

    <div><input type="submit" value="Upload"/></div>
</form>

Second, you'll want to throw this script at the bottom, don't forget to reference the plugin. If the form submission is successful, it'll close the window.

<script src="http://ajax.googleapis.com/ajax/libs/jquery/1.7/jquery.js"></script> 
<script src="http://malsup.github.com/jquery.form.js"></script> 

    <script>
       $(document).ready(function () {
          $('#certform').ajaxForm(function () {
          window.close();
          });
       });
    </script>

or you can add the AutoCompleteBox into the toolbox by clicking on it and then Choose Items, go to WPF Components, type in the filter AutoCompleteBox, which is on the System.Windows.Controls namespace and the just drag into your xaml file. This is way much easier than doing these other stuff, since the AutoCompleteBox is a native control.

It looks like there is actually a cross-platform way to do this that works on both iOS and Android (not sure about Windows). It uses only binding and does not require custom renderers (which seems rare). This is a mash-up of lots of googling, so thanks to anyone who I may have borrowed from...

I am assuming ViewCells, but this should work for Text or Image cells as well. I am only including the relevant code here beyond the typical text, image, etc.

On your page do something like this:

MyModel model1 = new MyModel();
MyModel model2 = new MyModel();

ListView list = new ListView
{
    ItemsSource = new List<MyModel> { model1, model2 };
    ItemTemplate = new DataTemplate( typeof(MyCell) )
};

Your custom Model might look something like this:

public class MyModel : INotifyPropertyChanged
{
    public event PropertyChangedEventHandler PropertyChanged;

    private Color _backgroundColor;

    public Color BackgroundColor 
    { 
        get { return _backgroundColor; } 
        set 
        { 
            _backgroundColor = value; 

            if ( PropertyChanged != null )
            {
                PropertyChanged( this, new PropertyChangedEventArgs( "BackgroundColor" ) );
            }
        }
    }

    public void SetColors( bool isSelected )
    {
        if ( isSelected )
        {
            BackgroundColor = Color.FromRgb( 0.20, 0.20, 1.0 );
        }
        else
        {
            BackgroundColor = Color.FromRgb( 0.95, 0.95, 0.95 ); 
        }
    }
}

Then for your ItemTemplate you need a custom cell class something like this:

public class MyCell : ViewCell
{
    public MyCell() : base()
    {
        RelativeLayout layout = new RelativeLayout();
        layout.SetBinding( Layout.BackgroundColorProperty, new Binding( "BackgroundColor" ) );

        View = layout;
    }
}

Then in your ItemSelected event handler, do the following. Note that 'selected' is an instance of MyModel used to track the currently selected item. I am only showing background color here, but I also use this technique to reverse highlight the text and detail text colors.

private void ItemSelected( object sender, ItemTappedEventArgs args )
{
    // Deselect previous
    if ( selected != null )
    {
        selected.SetColors( false );
    }

    // Select new
    selected = (list.SelectedItem as MyModel);
    selected.SetColors( true );
}

From Go 1.5 there's the "vendor experiment" that helps you manage dependencies. As of Go 1.6 this is no longer an experiment. Theres also some other options on the Go wiki..

Edit: as mentioned in this answer gopkg.in is a good option for pinning github-depdencies pre-1.5.

You need to use WITH ROLLBACK IMMEDIATE to boot other conections out with no regards to what or who is is already using it.

Or use WITH NO_WAIT to not hang and not kill existing connections. See http://www.blackwasp.co.uk/SQLOffline.aspx for details

These are my two suggestions.

1. Using classes. There is no need to specify width of the two other columns as they will be set to 15% each automatically by the browser.

   _x000D_

   _x000D_

       table { table-layout: fixed; }_x000D_
       .subject { width: 70%; }

   _x000D_

       <table>_x000D_
         <tr>_x000D_
           <th>From</th>_x000D_
           <th class="subject">Subject</th>_x000D_
           <th>Date</th>_x000D_
         </tr>_x000D_
       </table>

   _x000D_

   _x000D_
   _x000D_

2. Without using classes. Three different methods but the result is identical.

   a)

   _x000D_

   _x000D_

       table { table-layout: fixed; }_x000D_
       th+th { width: 70%; }_x000D_
       th+th+th { width: 15%; }

   _x000D_

       <table>_x000D_
         <tr>_x000D_
           <th>From</th>_x000D_
           <th>Subject</th>_x000D_
           <th>Date</th>_x000D_
         </tr>_x000D_
       </table>

   _x000D_

   _x000D_
   _x000D_

   b)

   _x000D_

   _x000D_

       table { table-layout: fixed; }_x000D_
       th:nth-of-type(2) { width: 70%; }

   _x000D_

       <table>_x000D_
         <tr>_x000D_
           <th>From</th>_x000D_
           <th>Subject</th>_x000D_
           <th>Date</th>_x000D_
         </tr>_x000D_
       </table>

   _x000D_

   _x000D_
   _x000D_

   c) This one is my favourite. Same as b) but with better browser support.

   _x000D_

   _x000D_

       table { table-layout: fixed; }_x000D_
       th:first-child+th { width: 70%; }

   _x000D_

       <table>_x000D_
         <tr>_x000D_
           <th>From</th>_x000D_
           <th>Subject</th>_x000D_
           <th>Date</th>_x000D_
         </tr>_x000D_
       </table>

   _x000D_

   _x000D_
   _x000D_

Two ways:

Use indexes:

double sum = 0;
for(int i = 0; i < m.size(); i++)
    sum += m.get(i);
return sum;

Use the "for each" style:

double sum = 0;
for(Double d : m)
    sum += d;
return sum;

var tds = document.getElementById("ctl00_ContentPlaceHolder1_Jobs_dlItems_ctl01_a").getElementsByTagName("td");
time = tds[0].firstChild.value;
address = tds[3].firstChild.value;

One obvious thing is that you will have to remove the comma here

receipt int(10),

but the actual problem is because of the line

amount double(10) NOT NULL,

change it to

amount double NOT NULL,

If you want to run a script to a database:

mysql -u user -p data_base_name_here < db.sql

Rewrite rules are pretty much written the same way with nginx: http://wiki.nginx.org/HttpRewriteModule#rewrite

Which rules are causing you trouble? I could help you translate those!

If you just want to check if that item exists:

IEnumerable<DataGridViewRow> rows = grdPdfs.Rows
            .Cast<DataGridViewRow>()
            .Where(r => r.Cells["SystemId"].Value.ToString().Equals(searchValue));
if (rows.Count() == 0) 
{
    // Not Found
} 
else 
{
    // Found
}

Or better

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

that tends to work best across all browsers and mobile

If you use Python 2, don't forget to add the UTF-8 file encoding comment on the first line of your script.

# -*- coding: UTF-8 -*-

This will fix some Unicode problems and make your life easier.

It gives you the remainder of a division.

int c=11, d=5;
cout << (c/d) * d + c % d; // gives you the value of c

The beauty of Visual Studio Code is

Ctrl + Shift + P

Hit it and search anything you want.

In your case, hit Ctrl + Shift + P and type fold all.

As far as I'm aware, you've got three options to install zsh on Mac OS X:

• Pre-built binary. The only one I know of is the one that ships with OS X; this is probably what you're running now.
• Use a package system (Ports, Homebrew).
• Install from source. Last time I did this it wasn't too difficult (./configure, make, make install).

To resume the working solutions in VisualStudio 2013 and 2015 too:

Add an include-path to the current project only

In Solution Explorer (a palette-window of the VisualStudio-mainwindow), open the shortcut menu for the project and choose Properties, and then in the left pane of the Property Pages dialog box, expand Configuration Properties and select VC++ Directories. Additional include- or lib-paths are specifyable there.

Its the what Stackunderflow and user1741137 say in the answers above. Its the what Microsoft explains in MSDN too.

Add an include-path to every new project automatically

Its the question, what Jay Elston is asking in a comment above and what is a very obvious and burning question in my eyes, what seems to be nonanswered here yet.

There exist regular ways to do it in VisualStudio (see CurlyBrace.com), what in my experience are not working properly. In the sense, that it works only once, and thereafter, it is no more expandable and nomore removable. The approach of Steve Wilkinson in another close related thread of StackOverflow, editing the Microsoft-Factory-XML-file in the ‘program files’ - directory is probably a risky hack, as it isnt expected by Microsoft to meet there something foreign. The effect is potentally unpredictable. Well, I like rather to judge it risky not much, but anyway the best way to make VisualStudio work incomprehensible at least for someone else.

The what is working fine compared to, is the editing the corresponding User-XML-file:

C:\Users\UserName\AppData\Local\Microsoft\MSBuild\v4.0\Microsoft.Cpp.Win32.user.props

or/and

C:\Users\UserName\AppData\Local\Microsoft\MSBuild\v4.0\Microsoft.Cpp.x64.user.props

For example:

<?xml version="1.0" encoding="utf-8"?>
<Project DefaultTargets="Build" ToolsVersion="4.0" xmlns="http://schemas.microsoft.com/developer/msbuild/2003">
  <ImportGroup Label="PropertySheets">
  </ImportGroup>
  <PropertyGroup Label="UserMacros" />
  <PropertyGroup>
    <IncludePath>C:\any-name\include;$(IncludePath)</IncludePath>
    <LibraryPath>C:\any-name\lib;$(LibraryPath)</LibraryPath>
  </PropertyGroup>
  <ItemDefinitionGroup />
  <ItemGroup />
</Project>

Where the directory ‘C:\any-name\include’ will get prepended to the present include-path and the directory ‘C:\any-name\lib’ to the library-path. Here, we can edit it ago in an extending and removing sense and remove it all, removing thewhole content of the tag .

Its the what makes VisualStudio itself, doing it in the regular way what CurlyBrace describes. As said, it isnt editable in the CurlyBrace-way thereafter nomore, but in the XML-editing-way it is.

For more insight, see Brian Tyler@MSDN-Blog 2009, what is admittedly not very fresh, but always the what Microsoft is linking to.

I have also used the following to submit a form (without actually submitting it) via Ajax:

  jQuery.get("process_form.php"+$("#form_id").serialize(), {}, 
    function() {
      alert("Okay!"); 
    });

android {
    compileSdkVersion 23
    buildToolsVersion '23.0.1'

defaultConfig {
    applicationId ""
    minSdkVersion 14
    targetSdkVersion 22
    versionCode 1
    versionName "1.0"
}
buildTypes {
    release {
        minifyEnabled false
        proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
    }
  }
}

dependencies {
compile fileTree(dir: 'libs', include: ['*.jar'])
compile 'com.google.code.gson:gson:2.3.1'
compile 'com.android.support:recyclerview-v7:23.0.0'
compile 'com.android.support:appcompat-v7:23.0.1'
}

More simpler single query oracle version.

Use Directory.GetDirectories to get the subdirectories of the directory specified by "your_directory_path". The result is an array of strings.

var directories = Directory.GetDirectories("your_directory_path");

By default, that only returns subdirectories one level deep. There are options to return all recursively and to filter the results, documented here, and shown in Clive's answer.

Avoiding an UnauthorizedAccessException

It's easily possible that you'll get an UnauthorizedAccessException if you hit a directory to which you don't have access.

You may have to create your own method that handles the exception, like this:

public class CustomSearcher
{ 
    public static List<string> GetDirectories(string path, string searchPattern = "*",
        SearchOption searchOption = SearchOption.AllDirectories)
    {
        if (searchOption == SearchOption.TopDirectoryOnly)
            return Directory.GetDirectories(path, searchPattern).ToList();

        var directories = new List<string>(GetDirectories(path, searchPattern));

        for (var i = 0; i < directories.Count; i++)
            directories.AddRange(GetDirectories(directories[i], searchPattern));

        return directories;
    }

    private static List<string> GetDirectories(string path, string searchPattern)
    {
        try
        {
            return Directory.GetDirectories(path, searchPattern).ToList();
        }
        catch (UnauthorizedAccessException)
        {
            return new List<string>();
        }
    }
}

And then call it like this:

var directories = CustomSearcher.GetDirectories("your_directory_path");

This traverses a directory and all its subdirectories recursively. If it hits a subdirectory that it cannot access, something that would've thrown an UnauthorizedAccessException, it catches the exception and just returns an empty list for that inaccessible directory. Then it continues on to the next subdirectory.

SyntaxError: Unexpected token o in JSON

This also happens when you forget to use the await keyword for a method that returns JSON data.

For example:

async function returnJSONData()
{
   return "{\"prop\": 2}";
}

var json_str = returnJSONData();
var json_obj = JSON.parse(json_str);

will throw an error because of the missing await. What is actually returned is a Promise [object], not a string.

To fix just add await as you're supposed to:

var json_str = await returnJSONData();

This should be pretty obvious, but the error is called on JSON.parse, so it's easy to miss if there's some distance between your await method call and the JSON.parse call.
