I am using angular 6 and I have been searching on best way to match password and confirm password. This can also be used to match any two inputs in a form. I used Angular Directives. I have been wanting to use them

ng g d compare-validators --spec false and i will be added in your module. Below is the directive

import { Directive, Input } from '@angular/core';
import { Validator, NG_VALIDATORS, AbstractControl, ValidationErrors } from '@angular/forms';
import { Subscription } from 'rxjs';

@Directive({
  // tslint:disable-next-line:directive-selector
  selector: '[compare]',
  providers: [{ provide: NG_VALIDATORS, useExisting: CompareValidatorDirective, multi: true}]
})
export class CompareValidatorDirective implements Validator {
  // tslint:disable-next-line:no-input-rename
  @Input('compare') controlNameToCompare;

  validate(c: AbstractControl): ValidationErrors | null {
    if (c.value.length < 6 || c.value === null) {
      return null;
    }
    const controlToCompare = c.root.get(this.controlNameToCompare);

    if (controlToCompare) {
      const subscription: Subscription = controlToCompare.valueChanges.subscribe(() => {
        c.updateValueAndValidity();
        subscription.unsubscribe();
      });
    }

    return controlToCompare && controlToCompare.value !== c.value ? {'compare': true } : null;
  }

}

Now in your component

<div class="col-md-6">
              <div class="form-group">
                <label class="bmd-label-floating">Password</label>
                <input type="password" class="form-control" formControlName="usrpass" [ngClass]="{ 'is-invalid': submitAttempt && f.usrpass.errors }">
                <div *ngIf="submitAttempt && signupForm.controls['usrpass'].errors" class="invalid-feedback">
                  <div *ngIf="signupForm.controls['usrpass'].errors.required">Your password is required</div>
                  <div *ngIf="signupForm.controls['usrpass'].errors.minlength">Password must be at least 6 characters</div>
                </div>
              </div>
            </div>
            <div class="col-md-6">
              <div class="form-group">
                <label class="bmd-label-floating">Confirm Password</label>
                <input type="password" class="form-control" formControlName="confirmpass" compare = "usrpass"
                [ngClass]="{ 'is-invalid': submitAttempt && f.confirmpass.errors }">
                <div *ngIf="submitAttempt && signupForm.controls['confirmpass'].errors" class="invalid-feedback">
                  <div *ngIf="signupForm.controls['confirmpass'].errors.required">Your confirm password is required</div>
                  <div *ngIf="signupForm.controls['confirmpass'].errors.minlength">Password must be at least 6 characters</div>
                  <div *ngIf="signupForm.controls['confirmpass'].errors['compare']">Confirm password and Password dont match</div>
                </div>
              </div>
            </div>

I hope this one helps

Comment by @Niagaradad helped me. I was entering the wrong password the whole time.

Notice the error message

ERROR 1045 (28000): Access denied for user 'ayaz'@'localhost' (using password: YES)

It says, Password: Yes. That means I am sending the password to SQL and that is wrong.

Usually root account doesn't have password if you haven't set one. If you have installed mysql via homebrew then root account won't have a password.

Here is the comment.

so, not exactly the same then. NO means you are not sending a password to MySQL. YES means you are sending a password to MySQL but the incorrect one. Did you specifically set a password for the mysql root user when you installed MySQL? By default there is no password so you can use mysql -u root -p and hit enter.

For me, adding Trusted_Connection=True to the connection string helped.

Use GNU passwd stdin flag.

From the man page:

   --stdin
          This option is used to indicate that passwd should read the new password from standard input, which can be a pipe.

NOTE: Only for root user.

Example

$ adduser foo 
$ echo "NewPass" |passwd foo --stdin
Changing password for user foo.
passwd: all authentication tokens updated successfully.

Alternatively you can use expect, this simple code will do the trick:

#!/usr/bin/expect
spawn passwd foo
expect "password:"
send "Xcv15kl\r"
expect "Retype new password:"
send "Xcv15kl\r"
interact

Results

$ ./passwd.xp 
spawn passwd foo
Changing password for user foo.
New password: 
Retype new password: 
passwd: all authentication tokens updated successfully.

I had the same issue.

Make sure that In SQL Server configuration --> SQL Server Services --> SQL Server Agent is enable

This solved my problem

A few comments:

• The Nyquist frequency is half the sampling rate.
• You are working with regularly sampled data, so you want a digital filter, not an analog filter. This means you should not use analog=True in the call to butter, and you should use scipy.signal.freqz (not freqs) to generate the frequency response.
• One goal of those short utility functions is to allow you to leave all your frequencies expressed in Hz. You shouldn't have to convert to rad/sec. As long as you express your frequencies with consistent units, the scaling in the utility functions takes care of the normalization for you.

Here's my modified version of your script, followed by the plot that it generates.

import numpy as np
from scipy.signal import butter, lfilter, freqz
import matplotlib.pyplot as plt


def butter_lowpass(cutoff, fs, order=5):
    nyq = 0.5 * fs
    normal_cutoff = cutoff / nyq
    b, a = butter(order, normal_cutoff, btype='low', analog=False)
    return b, a

def butter_lowpass_filter(data, cutoff, fs, order=5):
    b, a = butter_lowpass(cutoff, fs, order=order)
    y = lfilter(b, a, data)
    return y


# Filter requirements.
order = 6
fs = 30.0       # sample rate, Hz
cutoff = 3.667  # desired cutoff frequency of the filter, Hz

# Get the filter coefficients so we can check its frequency response.
b, a = butter_lowpass(cutoff, fs, order)

# Plot the frequency response.
w, h = freqz(b, a, worN=8000)
plt.subplot(2, 1, 1)
plt.plot(0.5*fs*w/np.pi, np.abs(h), 'b')
plt.plot(cutoff, 0.5*np.sqrt(2), 'ko')
plt.axvline(cutoff, color='k')
plt.xlim(0, 0.5*fs)
plt.title("Lowpass Filter Frequency Response")
plt.xlabel('Frequency [Hz]')
plt.grid()


# Demonstrate the use of the filter.
# First make some data to be filtered.
T = 5.0         # seconds
n = int(T * fs) # total number of samples
t = np.linspace(0, T, n, endpoint=False)
# "Noisy" data.  We want to recover the 1.2 Hz signal from this.
data = np.sin(1.2*2*np.pi*t) + 1.5*np.cos(9*2*np.pi*t) + 0.5*np.sin(12.0*2*np.pi*t)

# Filter the data, and plot both the original and filtered signals.
y = butter_lowpass_filter(data, cutoff, fs, order)

plt.subplot(2, 1, 2)
plt.plot(t, data, 'b-', label='data')
plt.plot(t, y, 'g-', linewidth=2, label='filtered data')
plt.xlabel('Time [sec]')
plt.grid()
plt.legend()

plt.subplots_adjust(hspace=0.35)
plt.show()

I had similar experience and it took me time to solve the problem. Though, my own case was ASP.Net MVC Core and Core framework. Setting Trusted_Connection=False; solved my problem.

Inside appsettings.json file

"ConnectionStrings": {
    "DefaultConnection": "Server=servername; Database=databasename; User Id=userid; Password=password; Trusted_Connection=False; MultipleActiveResultSets=true",
  },

start the sql server agent, that should fix your problem

and doesnt give any clues

Yes it does, unfortunately your code is ignoring all of those clues. Take a look at your exception handler:

catch (OleDbException  ex)
{
    MessageBox.Show(ex.Source);
    conn.Close();
}

All you're examining is the source of the exception. Which, in this case, is "Microsoft Access Database Engine". You're not examining the error message itself, or the stack trace, or any inner exception, or anything useful about the exception.

Don't ignore the exception, it contains information about what went wrong and why.

There are various logging tools out there (NLog, log4net, etc.) which can help you log useful information about an exception. Failing that, you should at least capture the exception message, stack trace, and any inner exception(s). Currently you're ignoring the error, which is why you're not able to solve the error.

In your debugger, place a breakpoint inside the catch block and examine the details of the exception. You'll find it contains a lot of information.

If you haven't actually registered any users with your existing format then you would be best to switch to using the BCrypt password encoder instead.

It's a lot less hassle, as you don't have to worry about salt at all - the details are completely encapsulated within the encoder. Using BCrypt is stronger than using a plain hash algorithm and it's also a standard which is compatible with applications using other languages.

There's really no reason to choose any of the other options for a new application.

Sql Server fire this error when your application don't have enough rights to access the database. there are several reason about this error . To fix this error you should follow the following instruction.

1. Try to connect sql server from your server using management studio . if you use windows authentication to connect sql server then set your application pool identity to server administrator .

2. if you use sql server authentication then check you connection string in web.config of your web application and set user id and password of sql server which allows you to log in .

3. if your database in other server(access remote database) then first of enable remote access of sql server form sql server property from sql server management studio and enable TCP/IP form sql server configuration manager .

4. after doing all these stuff and you still can't access the database then check firewall of server form where you are trying to access the database and add one rule in firewall to enable port of sql server(by default sql server use 1433 , to check port of sql server you need to check sql server configuration manager network protocol TCP/IP port).

5. if your sql server is running on named instance then you need to write port number with sql serer name for example 117.312.21.21/nameofsqlserver,1433.

6. If you are using cloud hosting like amazon aws or microsoft azure then server or instance will running behind cloud firewall so you need to enable 1433 port in cloud firewall if you have default instance or specific port for sql server for named instance.

7. If you are using amazon RDS or SQL azure then you need to enable port from security group of that instance.

8. If you are accessing sql server through sql server authentication mode them make sure you enabled "SQL Server and Windows Authentication Mode" sql server instance property.

   9. Restart your sql server instance after making any changes in property as some changes will require restart.

if you further face any difficulty then you need to provide more information about your web site and sql server .

blog_development doesn't exist

You can see this in sql by the 0 rows affected message

create it in mysql with

mysql> create database blog_development

However as you are using rails you should get used to using

$ rake db:create

to do the same task. It will use your database.yml file settings, which should include something like:

development:
  adapter: mysql2
  database: blog_development
  pool: 5

Also become familiar with:

$ rake db:migrate  # Run the database migration
$ rake db:seed     # Run thew seeds file create statements
$ rake db:drop     # Drop the database

If you check the length seperately, you can do the following:

var regularExpression  = /^[a-zA-Z]$/;

if (regularExpression.test(newPassword)) {
    alert("password should contain atleast one number and one special character");
    return false;
} 

A simple method of creating the service, adding headers and reading the JSON response,

private static void WebRequest()
{
    const string WEBSERVICE_URL = "<<Web Service URL>>";
    try
    {
        var webRequest = System.Net.WebRequest.Create(WEBSERVICE_URL);
        if (webRequest != null)
        {
            webRequest.Method = "GET";
            webRequest.Timeout = 20000;
            webRequest.ContentType = "application/json";
            webRequest.Headers.Add("Authorization", "Basic dcmGV25hZFzc3VudDM6cGzdCdvQ=");
            using (System.IO.Stream s = webRequest.GetResponse().GetResponseStream())
            {
                using (System.IO.StreamReader sr = new System.IO.StreamReader(s))
                {
                    var jsonResponse = sr.ReadToEnd();
                    Console.WriteLine(String.Format("Response: {0}", jsonResponse));
                }
            }
        }
    }
    catch (Exception ex)
    {
        Console.WriteLine(ex.ToString());
    }
}

The onkeyup event does "work" as you intend:

    else

I recommend to use SMO (Enable TCP/IP Network Protocol for SQL Server). However, it was not available in my case.

I rewrote the WMI commands from Krzysztof Kozielczyk to PowerShell.

# Enable TCP/IP

Get-CimInstance -Namespace root/Microsoft/SqlServer/ComputerManagement10 -ClassName ServerNetworkProtocol -Filter "InstanceName = 'SQLEXPRESS' and ProtocolName = 'Tcp'" |
Invoke-CimMethod -Name SetEnable

# Open the right ports in the firewall
New-NetFirewallRule -DisplayName 'MSSQL$SQLEXPRESS' -Direction Inbound -Action Allow -Protocol TCP -LocalPort 1433

# Modify TCP/IP properties to enable an IP address

$properties = Get-CimInstance -Namespace root/Microsoft/SqlServer/ComputerManagement10 -ClassName ServerNetworkProtocolProperty -Filter "InstanceName='SQLEXPRESS' and ProtocolName = 'Tcp' and IPAddressName='IPAll'"
$properties | ? { $_.PropertyName -eq 'TcpPort' } | Invoke-CimMethod -Name SetStringValue -Arguments @{ StrValue = '1433' }
$properties | ? { $_.PropertyName -eq 'TcpPortDynamic' } | Invoke-CimMethod -Name SetStringValue -Arguments @{ StrValue = '' }

# Restart SQL Server

Restart-Service 'MSSQL$SQLEXPRESS'

Config file changes are required to enable connections via localhost.

To connect through remote IPs, Login as a "root" user and run the below queries in mysql.

CREATE USER 'username'@'localhost' IDENTIFIED BY 'password';

GRANT ALL PRIVILEGES ON *.* TO 'username'@'localhost' WITH GRANT OPTION;

CREATE USER 'username'@'%' IDENTIFIED BY 'password';

GRANT ALL PRIVILEGES ON *.* TO 'username'@'%' WITH GRANT OPTION;

FLUSH PRIVILEGES;

This will create a new user that is accessible on localhost as well as from remote IPs.

Also comment the below line from your my.cnf file located in /etc/mysql/my.cnf

bind-address = 127.0.0.1

Restart your mysql using

sudo service mysql restart

Now you should be able to connect remotely to your mysql.

#Server Connection to MySQL:

import MySQLdb
conn = MySQLdb.connect(host= "localhost",
                  user="root",
                  passwd="newpassword",
                  db="engy1")
x = conn.cursor()

try:
   x.execute("""INSERT INTO anooog1 VALUES (%s,%s)""",(188,90))
   conn.commit()
except:
   conn.rollback()

conn.close()

edit working for me:

>>> import MySQLdb
>>> #connect to db
... db = MySQLdb.connect("localhost","root","password","testdb" )
>>> 
>>> #setup cursor
... cursor = db.cursor()
>>> 
>>> #create anooog1 table
... cursor.execute("DROP TABLE IF EXISTS anooog1")

I also had this problem. It was caused by the development server not deleting the django session after a debug abort in Aptana, with subsequent database deletion. (Meaning the id of a non-existent database record was still present in the session the next time the development server started)

To resolve this during development, I used

request.session.flush()

The following steps will help you to sort your problem out.

Steps: developer_identity.cer <= download from Apple mykey.p12 <= Your private key

Commands to follow:

    openssl x509 -in developer_identity.cer -inform DER -out developer_identity.pem -outform PEM

    openssl pkcs12 -nocerts -in mykey.p12 -out mykey.pem

    openssl pkcs12 -export -inkey mykey.pem -in developer_identity.pem -out iphone_dev.p12

Final p12 that we will require is iphone_dev.p12 file and the passphrase.

use this file as your p12 and then try. This indeed is the solution.:)

JSF is a beast. I may be missing something, but I used to solve similar problems by saving the desired message to a property of the bean, and then displaying the property via an outputText:

<h:outputText
    value="#{CreateNewPasswordBean.errorMessage}"
    render="#{CreateNewPasswordBean.errorMessage != null}" />

You may fill the column by double-clicking on the bottom right hand corner of the cell which you want to copy from (the point on the box that you would otherwise drag) and it will be applied to whole column.

NB: This doesn't work if you have the filter applied, nor if there is already something already in the cells below.

* {
  box-sizing: border-box;
}

#main_content {
  top: 160px;
  left: 160px;
  width: 800px;
  min-height: 500px;
  height: auto;
  background-color: #2185c5;
  position: relative;
}

#container {
  width: 50%;
  height: 50%;
  margin: auto;
  padding: 10px;
  position: absolute;
  border: 5px solid yellow;
  top: 0;
  left: 0;
  right: 0;
  bottom: 0;
}

In your Project properties(Right click on project, click on property button) ? Configuration Properties ? Build Events ? Post Build Events ? Command Line.

Edit and add one instruction to command line. for example copy botan.dll from source path to location where is being executed the program.

copy /Y "$(SolutionDir)ProjectDirs\x64\Botan\lib\botan.dll" "$(TargetDir)"

You can add the SVG as background-image of an empty :after or :before.

Here you go:

.anchor:before {
  display: block;
  content: ' ';
  background-image: url('../images/anchor.svg');
  background-size: 28px 28px;
  height: 28px;
  width: 28px;
}

Solution

I have implemented a small class with the help of which you can handle long clicks on TextView itself and Taps on the links in the TextView.

Layout

Hope this helps! You can find code here.

You don't need to have static in function definition

This because in.nextInt() only receive a int number, doesn't receive a new line. So you input 3 and press "Enter", the end of line is read by in.nextline().

Here is my code:

int nnames;
String names[];

System.out.print("How many names are you going to save: ");
Scanner in = new Scanner(System.in);
nnames = in.nextInt();
in.nextLine();
names = new String[nnames];

for (int i = 0; i < names.length; i++){
        System.out.print("Type a name: ");
        names[i] = in.nextLine();
}

git rebase didn't seem to work for me. After git rebase, when I try to push changes to my local branch, I kept getting an error ("hint: Updates were rejected because the tip of your current branch is behind its remote counterpart. Integrate the remote changes (e.g. 'git pull ...') before pushing again.") even after git pull. What finally worked for me was git merge.

git checkout <local_branch>
git merge <master> 

If you are a beginner like me, here is a good article on git merge vs git rebase. https://www.atlassian.com/git/tutorials/merging-vs-rebasing

1)just get your lib from here http://search.maven.org/

2)create a libs folder in app directory

3)paste ur library there

4)right click on ur library and click "Add as Library"

5)thats all u need to do!

I hope this will definitely gonna help you!!!!

You can use String arrays to add jComboBox items

String [] items = { "First item", "Second item", "Third item", "Fourth item" };

JComboBox comboOne = new JComboBox (items);

Another short solution:

from datetime import date

def diff_dates(date1, date2):
    return abs(date2-date1).days

def main():
    d1 = date(2013,1,1)
    d2 = date(2013,9,13)
    result1 = diff_dates(d2, d1)
    print '{} days between {} and {}'.format(result1, d1, d2)
    print ("Happy programmer's day!")

main()

You need to compile the bibtex file.

Suppose you have article.tex and article.bib. You need to run:

• latex article.tex (this will generate a document with question marks in place of unknown references)
• bibtex article (this will parse all the .bib files that were included in the article and generate metainformation regarding references)
• latex article.tex (this will generate document with all the references in the correct places)
• latex article.tex (just in case if adding references broke page numbering somewhere)

I ran into this problem when running PHPUnit in Elixir/Gulp, and Homestead as my Vagrant enviroment.

In my case I edited the .env file from DB_HOST=localhost to DB_HOST=192.168.10.10 where 192.168.10.10 is the IP of my Vagrant/Homestead host.

will I get the same results?

Not really. I don't know of a workaround for PHP 5.2, though.

What is the difference between new self and new static?

self refers to the same class in which the new keyword is actually written.

static, in PHP 5.3's late static bindings, refers to whatever class in the hierarchy you called the method on.

In the following example, B inherits both methods from A. The self invocation is bound to A because it's defined in A's implementation of the first method, whereas static is bound to the called class (also see get_called_class()).

class A {
    public static function get_self() {
        return new self();
    }

    public static function get_static() {
        return new static();
    }
}

class B extends A {}

echo get_class(B::get_self());  // A
echo get_class(B::get_static()); // B
echo get_class(A::get_self()); // A
echo get_class(A::get_static()); // A

In C, there's no (real, distinct type of) strings. Every C "string" is an array of chars, zero terminated.

Therefore, to extract a character c at index i from string your_string, just use

char c = your_string[i];

Index is base 0 (first character is your_string[0], second is your_string[1]...).

Check out this snippet:

Private Sub openDialog()
    Dim fd As Office.FileDialog

    Set fd = Application.FileDialog(msoFileDialogFilePicker)

   With fd

      .AllowMultiSelect = False

      ' Set the title of the dialog box.
      .Title = "Please select the file."

      ' Clear out the current filters, and add our own.
      .Filters.Clear
      .Filters.Add "Excel 2003", "*.xls"
      .Filters.Add "All Files", "*.*"

      ' Show the dialog box. If the .Show method returns True, the
      ' user picked at least one file. If the .Show method returns
      ' False, the user clicked Cancel.
      If .Show = True Then
        txtFileName = .SelectedItems(1) 'replace txtFileName with your textbox

      End If
   End With
End Sub

I think this is what you are asking for.

Bash allow u to use =~ to test if the substring is contained. Ergo, the use of negate will allow to test the opposite.

fullstring="123asdf123"
substringA=asdf
substringB=gdsaf
# test for contains asdf, gdsaf and for NOT CONTAINS gdsaf 
[[ $fullstring =~ $substring ]] && echo "found substring $substring in $fullstring"
[[ $fullstring =~ $substringB ]] && echo "found substring $substringB in $fullstring" || echo "failed to find"
[[ ! $fullstring =~ $substringB ]] && echo "did not find substring $substringB in $fullstring"

WARNING: setting this value too high may cause your system to experience a significant hiccup. The higher the value you set, the more virtual memory is allocated to the screen process when initiating the screen session. I set my ~/.screenrc to "defscrollback 123456789" and when I initiated a screen, my entire system froze up for a good 10 minutes before coming back to the point that I was able to kill the screen process (which was consuming 16.6GB of VIRT mem by then).

to set height of table to its container I must do:

1) set "position: absolute"

2) remove redundant contents of cells (!)

If you removed the make all line from your "fresh" target:

fresh :
    rm -f *.o $(EXEC)
    clear

You could simply run the command make fresh all, which will execute as make fresh; make all.

Some might consider this as a second instance of make, but it's certainly not a sub-instance of make (a make inside of a make), which is what your attempt seemed to result in.

If the project came with a Visual Studio project file, then that should already be configured to find the headers for you. If not, you'll have to add the include file directory to the project settings by right-clicking the project and selecting Properties, clicking on "C/C++", and adding the directory containing the include files to the "Additional Include Directories" edit box.

To get just the string value within the spinner use the following:

Pay attention to your dependency scope I was having the issue where when I invoke clean compile via Intellij, the pom would get downloaded, but the jar would not. There was a xxx.jar.lastUpdated file created. Then realized that the dependency scope was test, but I was triggering the compile. I deleted the repos, and triggered the mvn test, and issue was resolved.

What is it?

When you create an object in a .Net framework application, you don't need to think about how the data is stored in memory. Because the .Net Framework takes care of that for you. However, if you want to store the contents of an object to a file, send an object to another process or transmit it across the network, you do have to think about how the object is represented because you will need to convert to a different format. This conversion is called SERIALIZATION.

Uses for Serialization

Serialization allows the developer to save the state of an object and recreate it as needed, providing storage of objects as well as data exchange. Through serialization, a developer can perform actions like sending the object to a remote application by means of a Web Service, passing an object from one domain to another, passing an object through a firewall as an XML string, or maintaining security or user-specific information across applications.

Apply SerializableAttribute to a type to indicate that instances of this type can be serialized. Apply the SerializableAttribute even if the class also implements the ISerializable interface to control the serialization process.

All the public and private fields in a type that are marked by the SerializableAttribute are serialized by default, unless the type implements the ISerializable interface to override the serialization process. The default serialization process excludes fields that are marked with NonSerializedAttribute. If a field of a serializable type contains a pointer, a handle, or some other data structure that is specific to a particular environment, and cannot be meaningfully reconstituted in a different environment, then you might want to apply NonSerializedAttribute to that field.

See MSDN for more details.

Edit 1

Any reason to not mark something as serializable

When transferring or saving data, you need to send or save only the required data. So there will be less transfer delays and storage issues. So you can opt out unnecessary chunk of data when serializing.

If you are not in the default availability zone the results from overthink would return empty.

ec2-describe-tags \
   --region \
     $(curl -s http://169.254.169.254/latest/meta-data/placement/availability-zone  | sed -e "s/.$//") \
   --filter \
     resource-id=$(curl --silent http://169.254.169.254/latest/meta-data/instance-id)

If you want to add a filter to get a specific tag (elasticbeanstalk:environment-name in my case) then you can do this.

ec2-describe-tags \
   --region \
     $(curl -s http://169.254.169.254/latest/meta-data/placement/availability-zone  | sed -e "s/.$//") \
   --filter \
     resource-id=$(curl --silent http://169.254.169.254/latest/meta-data/instance-id) \
   --filter \
     key=elasticbeanstalk:environment-name | cut -f5

And to get only the value for the tag that I filtered on, we pipe to cut and get the fifth field.

  --region \
    $(curl -s http://169.254.169.254/latest/meta-data/placement/availability-zone  | sed -e "s/.$//") \
  --filter \
    resource-id=$(curl --silent http://169.254.169.254/latest/meta-data/instance-id) \
  --filter \
    key=elasticbeanstalk:environment-name | cut -f5

Syntax:

• return the element's text content: $(selector).text()
• set the element's text content to content: $(selector).text(content)
• set the element's text content using a callback function: $(selector).text(function(index, curContent))

JQuery - Change the text of a span element

npm decided to add a new command: npm fund that will provide more visibility to npm users on what dependencies are actively looking for ways to fund their work.

npm install will also show a single message at the end in order to let user aware that dependencies are looking for funding, it looks like this:

$ npm install
packages are looking for funding.
run `npm fund` for details.

Running npm fund <package> will open the url listed for that given package right in your browser.

I think you could do it by creating parameters in an object maybe?

var myObject = {}; for(var i=0;i<myArray.length;i++) {     myObject[ myArray[i] ]; } 

If you don't set them to anything, you'll just have an object with some parameters that are undefined. I'd have to write this myself to be sure though.

You might want to check the target of the click event that fires for the body instead of relying on stopPropagation.

Something like:

$("body").click
(
  function(e)
  {
    if(e.target.className !== "form_wrapper")
    {
      $(".form_wrapper").hide();
    }
  }
);

Also, the body element may not include the entire visual space shown in the browser. If you notice that your clicks are not registering, you may need to add the click handler for the HTML element instead.

Got it. Quite stupid, actually. It worked after I removed & added the SessionStateModule like so:

<configuration>
  ...
  <system.webServer>
    ...
    <modules>
      <remove name="Session" />
      <add name="Session" type="System.Web.SessionState.SessionStateModule"/>
      ...
    </modules>
  </system.webServer>
</configuration>

Simply adding it won't work since "Session" should have already been defined in the machine.config.

Now, I wonder if that is the usual thing to do. It surely doesn't seem so since it seems so crude...

Place this dependency, and dont forget to select : Include dependencies with "provided" scope

    <dependency>
        <groupId>javax.servlet</groupId>

        <version>3.0.1</version>
        <scope>provided</scope>
    </dependency>

if you give a 2D array to the plot function of matplotlib it will assume the columns to be lines:

If x and/or y is 2-dimensional, then the corresponding columns will be plotted.

In your case your shape is not accepted (100, 1, 1, 8000). As so you can using numpy squeeze to solve the problem quickly:

np.squeez doc: Remove single-dimensional entries from the shape of an array.

import numpy as np
import matplotlib.pyplot as plt

data = np.random.randint(3, 7, (10, 1, 1, 80))
newdata = np.squeeze(data) # Shape is now: (10, 80)
plt.plot(newdata) # plotting by columns
plt.show()

But notice that 100 sets of 80 000 points is a lot of data for matplotlib. I would recommend that you look for an alternative. The result of the code example (run in Jupyter) is:

You should initialize yours recordings. You are passing to adapter null

ArrayList<String> recordings = null; //You are passing this null

It's probably worth mentioning that as of Laravel 5, passing data to the view is now done like this:

return view("blog", ["posts"=>$posts]);

Or:

return view("blog", compact("posts"));

Documentation is available here.

Swift 5 Example with UILabel Extension

With the code below setting your margins is as easy as label.setMargins(15).

extension UILabel {
    func setMargins(_ margin: CGFloat = 10) {
        if let textString = self.text {
            var paragraphStyle = NSMutableParagraphStyle()
            paragraphStyle.firstLineHeadIndent = margin
            paragraphStyle.headIndent = margin
            paragraphStyle.tailIndent = -margin
            let attributedString = NSMutableAttributedString(string: textString)
            attributedString.addAttribute(.paragraphStyle, value: paragraphStyle, range: NSRange(location: 0, length: attributedString.length))
            attributedText = attributedString
        }
    }
}

In Visual Studio 2017 with a .NET Core console application do the following:

Right click on the Project in the Solution window, select "Properties", Debug (on the left side), and enter the arguments into the field "Application Arguments".

Note that they should be space-separated.

To do so without compiling the Regex first, use a lambda function - for example:

from re import match

values = ['123', '234', 'foobar']
filtered_values = list(filter(lambda v: match('^\d+$', v), values))

print(filtered_values)

Returns:

['123', '234']

filter() just takes a callable as it's first argument, and returns a list where that callable returned a 'truthy' value.

here is another solution to round only using floor, meaning, making sure calculated amount won't be bigger than the original amount (sometimes needed for transactions):

Math.floor(num* 100 )/100;

The only thing I would update in Apple code is the keyboardWillBeHidden: method, to provide smooth transition.

// Called when the UIKeyboardWillHideNotification is sent
- (void)keyboardWillBeHidden:(NSNotification*)aNotification
{
    UIEdgeInsets contentInsets = UIEdgeInsetsZero;

    [UIView animateWithDuration:0.4 animations:^{
        self.scrollView.contentInset = contentInsets;
    }];
    self.scrollView.scrollIndicatorInsets = contentInsets;

}

I won't stress much on the difference as it is already covered, but notice the below:

• android:backgroundTint android:backgroundTintMode are only available at API 21
• If you have a widget that has a png/vector drawable background set by android:background, and you want to change its default color, then you can use android:backgroundTint to add a shade to it.

example

<Button
    android:layout_width="50dp"
    android:layout_height="wrap_content"
    android:background="@android:drawable/ic_dialog_email" />

<Button
    android:layout_width="50dp"
    android:layout_height="wrap_content"
    android:background="@android:drawable/ic_dialog_email"
    android:backgroundTint="@color/colorAccent" />

Another example

If you try to change the accent color of the FloatingActionButton using android:background you won't notice a change, that is because it's already utilizes app:srcCompat, so in order to do that you can use android:backgroundTint instead

echo '\x12\x02'

will not be interpreted, and will literally write the string \x12\x02 (and append a newline) to the specified serial port. Instead use

echo -n ^R^B

which you can construct on the command line by typing CtrlVCtrlR and CtrlVCtrlB. Or it is easier to use an editor to type into a script file.

The stty command should work, unless another program is interfering. A common culprit is gpsd which looks for GPS devices being plugged in.

These are much much better references than w3schools (the most awful web reference ever made):

• How cookies work (quirksmode.org)
• MDN document.cookie

Examples derived from these references:

// sets the cookie cookie1
document.cookie = 'cookie1=test; expires=Sun, 1 Jan 2023 00:00:00 UTC; path=/'

// sets the cookie cookie2 (cookie1 is *not* overwritten)
document.cookie = 'cookie2=test; expires=Sun, 1 Jan 2023 00:00:00 UTC; path=/'

// remove cookie2
document.cookie = 'cookie2=; expires=Thu, 01 Jan 1970 00:00:00 UTC; path=/'

The Mozilla reference even has a nice cookie library you can use.

I have very simple way to do this. It worked out perfect for me.

Dictionary<string, string> types = new Dictionary<string, string>();

types.Add("1", "one");
types.Add("2", "two");
types.Add("3", "three");

Console.WriteLine("Please type a key to show its value: ");
string rLine = Console.ReadLine();

if(types.ContainsKey(rLine))
{
    string value_For_Key = types[rLine];
    Console.WriteLine("Value for " + rLine + " is" + value_For_Key);
}

Those are users. Check your /etc/passwd.

cd ~username takes you to that user's home directory.

eq is used to compare integers use equal '=' instead , example:

if [ 'AAA' = 'ABC' ];
then 
    echo "the same" 
else 
    echo "not the same"
fi

good luck

Open with append:

pFile2 = fopen("myfile2.txt", "a");

then just write to pFile2, no need to fseek().

The top answers led to a bug in my code where on the first of the month it would set a future date in the current month. Here is what I did,

curDate = new Date(); // Took current date as an example
prvDate = new Date(0); // Date set to epoch 0
prvDate.setUTCMilliseconds((curDate - (5 * 24 * 60 * 60 * 1000))); //Set epoch time

Since web is evolving quickly, some things changes with time. For security issues, you might want to use the rel="noopener" attribute in conjuncture with your target="_blank".

Like stated in Google Dev Documentation, the other page can access your window object with the window.opener property. Your external link should looks like this now:

<a href="http://www.starfall.com/" target="_blank" rel="noopener">Starfall</a>

There are two kinds of cascades in Doctrine:

1) ORM level - uses cascade={"remove"} in the association - this is a calculation that is done in the UnitOfWork and does not affect the database structure. When you remove an object, the UnitOfWork will iterate over all objects in the association and remove them.

2) Database level - uses onDelete="CASCADE" on the association's joinColumn - this will add On Delete Cascade to the foreign key column in the database:

@ORM\JoinColumn(name="father_id", referencedColumnName="id", onDelete="CASCADE")

I also want to point out that the way you have your cascade={"remove"} right now, if you delete a Child object, this cascade will remove the Parent object. Clearly not what you want.

Your syntax is incorrect.

card_value = $(array[i]).val(); or card_value = array[i].value;

array[i] is not a jQuery object (for some reason).

Checking your browser's console can be helpful for things like this.

I see that this is answered already, but I believe I have a simple jQuery solution ( jQuery is not even really needed; I just enjoy using it ):

I suggest counting the line breaks in the textarea text and setting the rows attribute of the textarea accordingly.

var text = jQuery('#your_textarea').val(),
    // look for any "\n" occurences
    matches = text.match(/\n/g),
    breaks = matches ? matches.length : 2;

jQuery('#your_textarea').attr('rows',breaks + 2);

You might also consider the smart_open module, which supports iterators:

from smart_open import smart_open

# stream lines from an S3 object
for line in smart_open('s3://mybucket/mykey.txt', 'rb'):
    print(line.decode('utf8'))

and context managers:

with smart_open('s3://mybucket/mykey.txt', 'rb') as s3_source:
    for line in s3_source:
         print(line.decode('utf8'))

    s3_source.seek(0)  # seek to the beginning
    b1000 = s3_source.read(1000)  # read 1000 bytes

Find smart_open at https://pypi.org/project/smart_open/

Try setting the height of the html element to 100% as well.

html {
    min-height: 100%;
    overflow-y: scroll;
}    
body {
     min-height: 100%;
}

Reference from this answer..

It maybe useful to add that if you're seeing this error message and you're not using some kind of restricted container based hosting (e.g. OpenVZ) then the problem maybe that the kernel is missing the nat modules. To check run:

modinfo iptable_nat

Which should print out the location of the module, if it prints an ERROR then you know that is your problem. There are also dependent modules like nf_nat which might be missing so you'll have to dig deeper if the iptable_nat module is there but fails. If it is missing you'll need to get another kernel and modules, or if you're rolling your own ensure that the kernel config contains CONFIG_IP_NF_NAT=m (for IPv4 NAT).

For info the relevant kernel module is usually found in one of these locations:

ls /lib/modules/`uname -r`/kernel/net/netfilter/
ls /lib/modules/`uname -r`/kernel/net/ipv4/netfilter/

And if you're running IPv6 also look here:

ls /lib/modules/`uname -r`/kernel/net/ipv6/netfilter/

Why not just iterate through the string?

a_string="abcd"
for letter in a_string:
    print letter

returns

a
b
c
d

So, in pseudo-ish code, I would do this:

user_string = raw_input()
list_of_output = []
for letter in user_string:
   list_of_output.append(morse_code_ify(letter))

output_string = "".join(list_of_output)

Note: the morse_code_ify function is pseudo-code.

You definitely want to make a list of the characters you want to output rather than just concatenating on them on the end of some string. As stated above, it's O(n^2): bad. Just append them onto a list, and then use "".join(the_list).

As a side note: why are you removing the spaces? Why not just have morse_code_ify(" ") return a "\n"?

All previous answers are correct, here is one more and easy way to do it. For example, create a Dict data structure to serialize and deserialize an object

(Notice None is Null in python and I'm intentionally using this to demonstrate how you can store null and convert it to json null)

import json
print('serialization')
myDictObj = { "name":"John", "age":30, "car":None }
##convert object to json
serialized= json.dumps(myDictObj, sort_keys=True, indent=3)
print(serialized)
## now we are gonna convert json to object
deserialization=json.loads(serialized)
print(deserialization)

Have you tried (from a command line)

java -jar jbpm-installer-3.2.7.jar

or double clicking it with the mouse ?

Found this and this by googling.

Hope it helps

This one worked for me:

ServicePointManager.SecurityProtocol = SecurityProtocolType.Tls12;

I try this it solved.

 AlertDialog.Builder builder = new AlertDialog.Builder(
                   this);
            builder.setCancelable(true);
            builder.setTitle("Opss!!");

            builder.setMessage("You Don't have anough coins to withdraw. ");
            builder.setMessage("Please read the Withdraw rules.");
            builder.setInverseBackgroundForced(true);
            builder.setPositiveButton("OK",
                    (dialog, which) -> dialog.dismiss());
            builder.create().show();

You can also get an EntityManager using PersistenceContext or Autowired annotation, but be aware that it will not be thread-safe.

@PersistenceContext
private EntityManager entityManager;

There's no need to require a big library like jQuery to accomplish this, if you don't want to. To achieve this with built-in DOM manipulation, get a collection of the li siblings in an array, and on click, check the indexOf the clicked element in that array.

const lis = [...document.querySelectorAll('#wizard > li')];_x000D_
lis.forEach((li) => {_x000D_
  li.addEventListener('click', () => {_x000D_
    const index = lis.indexOf(li);_x000D_
    console.log(index);_x000D_
  });_x000D_
});

<ul id="wizard">_x000D_
    <li>Step 1</li>_x000D_
    <li>Step 2</li>_x000D_
</ul>

Or, with event delegation:

const lis = [...document.querySelectorAll('#wizard li')];_x000D_
document.querySelector('#wizard').addEventListener('click', ({ target }) => {_x000D_
  // Make sure the clicked element is a <li> which is a child of wizard:_x000D_
  if (!target.matches('#wizard > li')) return;_x000D_
  _x000D_
  const index = lis.indexOf(target);_x000D_
  console.log(index);_x000D_
});

<ul id="wizard">_x000D_
    <li>Step 1</li>_x000D_
    <li>Step 2</li>_x000D_
</ul>

Or, if the child elements may change dynamically (like with a todo list), then you'll have to construct the array of lis on every click, rather than beforehand:

const wizard = document.querySelector('#wizard');_x000D_
wizard.addEventListener('click', ({ target }) => {_x000D_
  // Make sure the clicked element is a <li>_x000D_
  if (!target.matches('li')) return;_x000D_
  _x000D_
  const lis = [...wizard.children];_x000D_
  const index = lis.indexOf(target);_x000D_
  console.log(index);_x000D_
});

<ul id="wizard">_x000D_
    <li>Step 1</li>_x000D_
    <li>Step 2</li>_x000D_
</ul>

//====================================================
//                  textFieldShouldReturn:
//====================================================
-(BOOL) textFieldShouldReturn:(UITextField*) textField { 
    [textField resignFirstResponder];
    if(textField.returnKeyType != UIReturnKeyDone){
        [[textField.superview viewWithTag: self.nextTextField] becomeFirstResponder];
    }
    return YES;
}

If you include the library System.Data.Entity you can use an overload of the Include() method which takes a lambda expression instead of a string. You can then Select() over children with Linq expressions rather than string paths.

return DatabaseContext.Applications
     .Include(a => a.Children.Select(c => c.ChildRelationshipType));

If you are using a database that supports map-reduce, like couchdb, storing tags in a plain text field or list field is indeed the best way. Example:

tagcloud: {
  map: function(doc){ 
    for(tag in doc.tags){ 
      emit(doc.tags[tag],1) 
    }
  }
  reduce: function(keys,values){
    return values.length
  }
}

Running this with group=true will group the results by tag name, and even return a count of the number of times that tag was encountered. It's very similar to counting the occurrences of a word in text.

foreach my $key (keys %$ad_grp_ref) {
    ...
}

Perl::Critic and daxim recommend the style

foreach my $key (keys %{ $ad_grp_ref }) {
    ...
}

out of concerns for readability and maintenance (so that you don't need to think hard about what to change when you need to use %{ $ad_grp_obj[3]->get_ref() } instead of %{ $ad_grp_ref })

If you were to use the C library then this could be done:

time_t t;
struct tm * timeinfo;

time (&t);
timeinfo = localtime (&t);

NSLog(@"Hour: %d Minutes: %d", timeinfo->tm_hour, timeinfo->tm_min);

And using Swift:

var t = time_t()
time(&t)
let x = localtime(&t)

println("Hour: \(x.memory.tm_hour) Minutes: \(x.memory.tm_min)")

For further guidance see: http://www.cplusplus.com/reference/ctime/localtime/

To avoid this sort of trouble, you can use replace (which takes a plain string) instead of replaceAll (which takes a regular expression). You will still need to escape backslashes, but not in the wild ways required with regular expressions.

Something else to check is make sure viewstate is on (I just solved this yesterday). If you don't have viewstate on, the gridview will be blank until you load it again.

If you just call exit in Bash without any parameters, it will return the exit code of the last command. Combined with OR, Bash should only invoke exit, if the previous command fails. But I haven't tested this.

command1 || exit;
command2 || exit;

Bash will also store the exit code of the last command in the variable $?.

You can do this as follows:

std::sort(v.begin(), v.end());
v.erase(std::unique(v.begin(), v.end()), v.end());

It will be better for you to write your code like this.

In your Controller Write this code.

    function new_blank_order_summary() {
     $query = $this->sales_model->order_summary_insert();
     if($query) {
        $this->load->view('sales/new_blank_order_summary'); 
    } else {
        $this->load->view('sales/data_insertion_failed');
    }
  }

and in your Model

function order_summary_insert() {
    $orderLines = trim(xss_clean($this->input->post('orderlines')));
    $customerName = trim(xss_clean($this->input->post('customer')));
    $data = array(
        'OrderLines'=>$orderLines,
        'CustomerName'=>$customerName
    );

    $this->db->insert('Customer_Orders',$data);
    return ($this->db->affected_rows() != 1) ? false : true;
}

You can't downcast. If the parent object is created, it cannot be cast to the child.

One suggested workaround would be to Create an interface which the parent implements. Have the child override functionality if needed or just expose the parents functionality. Change the cast to be an interface and do the operations.

Edit: May be could also check if the object is a SkyfilterClient using is keyword

   if(networkClient is SkyfilterClient)
   {

   }

This changed again in Angular2 RC.5

I will update the example below but it's the last day before vacation.

This Plunker example demonstrates how to dynamically create components in RC.5

Update - use ViewContainerRef.createComponent()

Because DynamicComponentLoader is deprecated, the approach needs to be update again.

@Component({
  selector: 'dcl-wrapper',
  template: `<div #target></div>`
})
export class DclWrapper {
  @ViewChild('target', {read: ViewContainerRef}) target;
  @Input() type;
  cmpRef:ComponentRef;
  private isViewInitialized:boolean = false;

  constructor(private resolver: ComponentResolver) {}

  updateComponent() {
    if(!this.isViewInitialized) {
      return;
    }
    if(this.cmpRef) {
      this.cmpRef.destroy();
    }
   this.resolver.resolveComponent(this.type).then((factory:ComponentFactory<any>) => {
      this.cmpRef = this.target.createComponent(factory)
      // to access the created instance use
      // this.compRef.instance.someProperty = 'someValue';
      // this.compRef.instance.someOutput.subscribe(val => doSomething());
    });
  }

  ngOnChanges() {
    this.updateComponent();
  }

  ngAfterViewInit() {
    this.isViewInitialized = true;
    this.updateComponent();  
  }

  ngOnDestroy() {
    if(this.cmpRef) {
      this.cmpRef.destroy();
    }    
  }
}

Update - use loadNextToLocation

  @ViewChild('target', {read: ViewContainerRef}) target;
  @Input() type;
  cmpRef:ComponentRef;
  private isViewInitialized:boolean = false;

  constructor(private dcl:DynamicComponentLoader) {}

  updateComponent() {
    // should be executed every time `type` changes but not before `ngAfterViewInit()` was called 
    // to have `target` initialized

    }
    if(this.cmpRef) {

original

Not entirely sure from your question what your requirements are but I think this should do what you want.

The Tabs component gets an array of types passed and it creates "tabs" for each item in the array.

@Component({
  selector: 'dcl-wrapper',
  template: `<div #target></div>`
})
export class DclWrapper {
  constructor(private elRef:ElementRef, private dcl:DynamicComponentLoader) {}
  @Input() type;

  ngOnChanges() {
    if(this.cmpRef) {
      this.cmpRef.dispose();
    }
    this.dcl.loadIntoLocation(this.type, this.elRef, 'target').then((cmpRef) => {
      this.cmpRef = cmpRef;
    });
  }
}

@Component({
  selector: 'c1',
  template: `<h2>c1</h2>`

})
export class C1 {
}

@Component({
  selector: 'c2',
  template: `<h2>c2</h2>`

})
export class C2 {
}

@Component({
  selector: 'c3',
  template: `<h2>c3</h2>`

})
export class C3 {
}

@Component({
  selector: 'my-tabs',
  directives: [DclWrapper],
  template: `
  <h2>Tabs</h2>
  <div *ngFor="let tab of tabs">
    <dcl-wrapper [type]="tab"></dcl-wrapper>
  </div>
`
})
export class Tabs {
  @Input() tabs;
}


@Component({
  selector: 'my-app',
  directives: [Tabs]
  template: `
  <h2>Hello {{name}}</h2>
  <my-tabs [tabs]="types"></my-tabs>
`
})
export class App {
  types = [C3, C1, C2, C3, C3, C1, C1];
}

Plunker example beta.15 (not based on your Plunker)

There is also a way to pass data along that can be passed to the dynamically created component like (someData would need to be passed like type)

    this.dcl.loadIntoLocation(this.type, this.elRef, 'target').then((cmpRef) => {
  cmpRef.instance.someProperty = someData;
  this.cmpRef = cmpRef;
});

There is also some support to use dependency injection with shared services.

For more details see https://angular.io/docs/ts/latest/cookbook/dynamic-component-loader.html

I'm a little late to the game, but this may help others.

In my case my jenkins master has a shared external resource, which is allocated to jenkins jobs by the external-resource-dispatcher-plugin. Due to bug JENKINS-19439 in the plugin (which is in beta), I found that my resource had been locked by a previous job, but wasn't unlocked when that previous job was cancelled.

To find out if a resource is currently in the locked state, navigate to the affected jenkins node, Jenkins -> Manage Jenkins -> Manage Nodes -> master

You should see the current state of any external resources. If any are unexpectedly locked this may be the reason why jobs are waiting for an executor.

I couldn't find any details of how to manually resolve this issue.
Restarting jenkins didn't resolve the problem.
In the end I went with the brutal approach:

• Remove the external resource
  (see Jenkins -> Manage Jenkins -> Manage Nodes -> master -> configure)
• Restart jenkins
• Re-create the external resource

what you're looking for is SUBSTITUTE:

=SUBSTITUTE(A2,"Author","Authoring")

Will substitute Author for Authoring without messing with everything else

Just to be explicit - Yes, the error is saying you cannot point your browser directly at file://some/path/some.html

Here are some options to quickly spin up a local web server to let your browser render local files

Python 2

If you have Python installed...

1. Change directory into the folder where your file some.html or file(s) exist using the command cd /path/to/your/folder

2. Start up a Python web server using the command python -m SimpleHTTPServer

This will start a web server to host your entire directory listing at http://localhost:8000

3. You can use a custom port python -m SimpleHTTPServer 9000 giving you link: http://localhost:9000

This approach is built in to any Python installation.

Python 3

Do the same steps, but use the following command instead python3 -m http.server

Node.js

Alternatively, if you demand a more responsive setup and already use nodejs...

1. Install http-server by typing npm install -g http-server

2. Change into your working directory, where yoursome.html lives

3. Start your http server by issuing http-server -c-1

This spins up a Node.js httpd which serves the files in your directory as static files accessible from http://localhost:8080

Ruby

If your preferred language is Ruby ... the Ruby Gods say this works as well:

ruby -run -e httpd . -p 8080

PHP

Of course PHP also has its solution.

php -S localhost:8000

There is something out there, context aware resizing, don't know if you will be able to use it, but it's worth looking at, that's for sure

A nice video demo (Enlarging appears towards the middle) http://www.youtube.com/watch?v=vIFCV2spKtg

Here there could be some code. http://www.semanticmetadata.net/2007/08/30/content-aware-image-resizing-gpl-implementation/

Was that overkill? Maybe there are some easy filters you can apply to an enlarged image to blur the pixels a bit, you could look into that.

Try:

$(document).ready(function() {
    $('#contact-form').validate({submitHandler: function(form) {
         var data = $('#contact-form').serialize();   
         $.post(
              'url_request',
               {data: data},
               function(response){
                  console.log(response);
               }
          );
         }
    });
});

I use

select /*+ parallel(a) */  count(1) from table_name a;

Your value:

this.element = $(id);

is a jQuery object, not a pure Canvas element.

To turn it back so you can call getContext(), call this.element.get(0), or better yet store the real element and not the jQuery object:

function canvasLayer(location, id) {

    this.width = $(window).width();
    this.height = $(window).height();
    this.element = document.createElement('canvas');

    $(this.element)
       .attr('id', id)
       .text('unsupported browser')
       .attr('width', this.width)       // for pixels
       .attr('height', this.height)
       .width(this.width)               // for CSS scaling
       .height(this.height)
       .appendTo(location);

    this.context = this.element.getContext("2d");
}

See running code at http://jsfiddle.net/alnitak/zbaMh/, ideally using the Chrome Javascript Console so you can see the resulting object in the debug output.

SELECT TOP 14 A, B, C
  FROM MyDatabase
  Where EXISTS 
   (
     Select Distinct[A] FROM MyDatabase
    )

I was facing the same issue and the reason was single backslah. I used double backslash in my "Data source" and it worked

connetionString = "Data Source=localhost\\SQLEXPRESS;Database=databasename;Integrated Security=SSPI";

Use VIEW. The same classes can be mapped to different tables/views using entity name, so you won't even have much of a duplication. Being there, done that, works OK.

Plain JDBC has another hidden problem: it's unaware of Hibernate session cache, so if something got cached till the end of the transaction and not flushed from Hibernate session, JDBC query won't find it. Could be very puzzling sometimes.

int result = 0;


 for (int i=0; i < positiveInteger; i++)
    {
        result = startingNumber + 1;
        cout << result;
    }

it's 2021 and here's a fantastically easy plugin to upload anything:

https://pqina.nl/filepond/?ref=pqina

add your element:

<input type="file" 
class="filepond"
name="filepond" 
multiple 
data-allow-reorder="true"
data-max-file-size="3MB"
data-max-files="3">

Register any additional plugins:

  FilePond.registerPlugin(
FilePondPluginImagePreview,  
FilePondPluginImageExifOrientation,  
FilePondPluginFileValidateSize,  
FilePondPluginImageEdit);

Then wire in the element:

// Select the file input and use 
// create() to turn it into a pond
FilePond.create(
  document.querySelector('input'),

  // Use Doka.js as image editor
  imageEditEditor: Doka.create({
    utils: ['crop', 'filter', 'color']
  })
);

I use this with the additional Doka image editor to upload and transform images at https://www.yoodu.co.uk

crazy simple to setup and the guys who run it are great at support.

As you can tell I'm a fanboy.

Another way to applyhorizontalalignment and rotation to each tick label is doing a for loop over the tick labels you want to change:

import numpy as np
import matplotlib.pyplot as plt
import datetime as dt

now = dt.datetime.now()
hours = [now + dt.timedelta(minutes=x) for x in range(0,24*60,10)]
days = [now + dt.timedelta(days=x) for x in np.arange(0,30,1/4.)]
hours_value = np.random.random(len(hours))
days_value = np.random.random(len(days))

fig, axs = plt.subplots(2)
fig.subplots_adjust(hspace=0.75)
axs[0].plot(hours,hours_value)
axs[1].plot(days,days_value)

for label in axs[0].get_xmajorticklabels() + axs[1].get_xmajorticklabels():
    label.set_rotation(30)
    label.set_horizontalalignment("right")

And here is an example if you want to control the location of major and minor ticks:

import numpy as np
import matplotlib.pyplot as plt
import datetime as dt

fig, axs = plt.subplots(2)
fig.subplots_adjust(hspace=0.75)
now = dt.datetime.now()
hours = [now + dt.timedelta(minutes=x) for x in range(0,24*60,10)]
days = [now + dt.timedelta(days=x) for x in np.arange(0,30,1/4.)]

axs[0].plot(hours,np.random.random(len(hours)))
x_major_lct = mpl.dates.AutoDateLocator(minticks=2,maxticks=10, interval_multiples=True)
x_minor_lct = matplotlib.dates.HourLocator(byhour = range(0,25,1))
x_fmt = matplotlib.dates.AutoDateFormatter(x_major_lct)
axs[0].xaxis.set_major_locator(x_major_lct)
axs[0].xaxis.set_minor_locator(x_minor_lct)
axs[0].xaxis.set_major_formatter(x_fmt)
axs[0].set_xlabel("minor ticks set to every hour, major ticks start with 00:00")

axs[1].plot(days,np.random.random(len(days)))
x_major_lct = mpl.dates.AutoDateLocator(minticks=2,maxticks=10, interval_multiples=True)
x_minor_lct = matplotlib.dates.DayLocator(bymonthday = range(0,32,1))
x_fmt = matplotlib.dates.AutoDateFormatter(x_major_lct)
axs[1].xaxis.set_major_locator(x_major_lct)
axs[1].xaxis.set_minor_locator(x_minor_lct)
axs[1].xaxis.set_major_formatter(x_fmt)
axs[1].set_xlabel("minor ticks set to every day, major ticks show first day of month")
for label in axs[0].get_xmajorticklabels() + axs[1].get_xmajorticklabels():
    label.set_rotation(30)
    label.set_horizontalalignment("right")

Just to make this absolutely clear for all:

A .MDF file is “typically” a SQL Server data file however it is important to note that it does NOT have to be.

This is because .MDF is nothing more than a recommended/preferred notation but the extension itself does not actually dictate the file type.

To illustrate this, if someone wanted to create their primary data file with an extension of .gbn they could go ahead and do so without issue.

To qualify the preferred naming conventions:

• .mdf - Primary database data file.
• .ndf - Other database data files i.e. non Primary.
• .ldf - Log data file.

I was also trying to achieve this. From above codes, what I understood was that you can call getch() function multiple times in order to get both bytes getting from the function. So the ord() function is not necessary if you are just looking to use with byte objects.

while True :
    if m.kbhit() :
        k = m.getch()
        if b'\r' == k :
            break
        elif k == b'\x08'or k == b'\x1b':
            # b'\x08' => BACKSPACE
            # b'\x1b' => ESC
            pass
        elif k == b'\xe0' or k == b'\x00':
            k = m.getch()
            if k in [b'H',b'M',b'K',b'P',b'S',b'\x08']:
                # b'H' => UP ARROW
                # b'M' => RIGHT ARROW
                # b'K' => LEFT ARROW
                # b'P' => DOWN ARROW
                # b'S' => DELETE
                pass
            else:
                print(k.decode(),end='')
        else:
            print(k.decode(),end='')

This code will work print any key until enter key is pressed in CMD or IDE (I was using VS CODE) You can customize inside the if for specific keys if needed

I tried the first few solutions and didn't work for me. Mainly the problem with attributes being removed like the other have already mentioned. I would say my approach is very similar to Jimmy by using the XElement constructors that taking object as parameters.

public static XElement RemoveAllNamespaces(this XElement element)
{
    return new XElement(element.Name.LocalName,
                        element.HasAttributes ? element.Attributes().Select(a => new XAttribute(a.Name.LocalName, a.Value)) : null,
                        element.HasElements ? element.Elements().Select(e => RemoveAllNamespaces(e)) : null,
                        element.Value);
}

I'm going to go a different route to the rest here, which try to tell if a variable is a specific, or a member of a specific set, of types.
JS is built on ducktyping; if something quacks like a string, we can and should use it like a string.

Is 7 a string? Then why does /\d/.test(7) work?
Is {toString:()=>('hello there')} a string? Then why does ({toString:()=>('hello there')}) + '\ngeneral kenobi!' work?
These aren't questions about should the above work, the point is they do.

So I made a duckyString() function
Below I test many cases not catered for by other answers. For each the code:

• sets a string-like variable
• runs an identical string operation on it and a real string to compare outputs (proving they can be treated like strings)
• converts the string-like to a real string to show you duckyString() to normalise inputs for code that expects real strings

text = 'hello there';
out(text.replace(/e/g, 'E') + ' ' + 'hello there'.replace(/e/g, 'E'));
out('Is string? ' + duckyString(text) + '\t"' + duckyString(text, true) + '"\n');

text = new String('oh my');
out(text.toUpperCase() + ' ' + 'oh my'.toUpperCase());
out('Is string? ' + duckyString(text) + '\t"' + duckyString(text, true) + '"\n');

text = 368;
out((text + ' is a big number') + ' ' + ('368' + ' is a big number'));
out('Is string? ' + duckyString(text) + '\t"' + duckyString(text, true) + '"\n');

text = ['\uD83D', '\uDE07'];
out(text[1].charCodeAt(0) + ' ' + ''[1].charCodeAt(0));
out('Is string? ' + duckyString(text) + '\t"' + duckyString(text, true) + '"\n');

function Text() { this.math = 7; }; Text.prototype = {toString:function() { return this.math + 3 + ''; }}
text = new Text();
out(String.prototype.match.call(text, '0') + ' ' + text.toString().match('0'));
out('Is string? ' + duckyString(text) + '\t"' + duckyString(text, true) + '"\n');

This is in the same vein as !!x as opposed to x===true and testing if something is array-like instead of necessitating an actual array.
jQuery objects; are they arrays? No. Are they good enough? Yeah, you can run them through Array.prototype functions just fine.
It's this flexibility that gives JS its power, and testing for strings specifically makes your code less interoperable.

The output of the above is:

hEllo thErE hEllo thErE
Is string? true "hello there"

OH MY OH MY
Is string? true "oh my"

368 is a big number 368 is a big number
Is string? true "368"

56839 56839
Is string? true ""

0 0
Is string? true "10"

So, it's all about why you want to know if something's a string.
If, like me, you arrived here from google and wanted to see if something was string-like, here's an answer.
It isn't even expensive unless you're working with really long or deeply nested char arrays.
This is because it is all if statements, no function calls like .toString().
_{Except if you're trying to see if a char array with objects that only have toString()'s or multi-byte characters, in which case there's no other way to check except to make the string, and count characters the bytes make up, respectively}

function duckyString(string, normalise, unacceptable) {
    var type = null;
    if (!unacceptable)
        unacceptable = {};
    if (string && !unacceptable.chars && unacceptable.to == null)
        unacceptable.to = string.toString == Array.prototype.toString;

    if (string == null)
        ;

    //tests if `string` just is a string
    else if (
        !unacceptable.is &&
        (typeof string == 'string' || string instanceof String)
    )
        type = 'is';

    //tests if `string + ''` or `/./.test(string)` is valid
    else if (
        !unacceptable.to &&
        string.toString && typeof string.toString == 'function' && string.toString != Object.prototype.toString
    )
        type = 'to';

    //tests if `[...string]` is valid
    else if (
        !unacceptable.chars &&
        (string.length > 0 || string.length == 0)
    ) {
        type = 'chars';
        //for each char
        for (var index = 0; type && index < string.length; ++index) {
            var char = string[index];

            //efficiently get its length
            var length = ((duckyString(char, false, {to:true})) ?
                char :
                duckyString(char, true) || {}
            ).length;

            if (length == 1)
                continue;

            //unicode surrogate-pair support
            char = duckyString(char, true);
            length = String.prototype[Symbol && Symbol.iterator];
            if (!(length = length && length.call(char)) || length.next().done || !length.next().done)
                type = null;
        }
    }

    //return true or false if they dont want to auto-convert to real string
    if (!(type && normalise))
        //return truthy or falsy with <type>/null if they want why it's true
        return (normalise == null) ? type != null : type;

    //perform conversion
    switch (type) {
    case 'is':
        return string;
    case 'to':
        return string.toString();
    case 'chars':
        return Array.from(string).join('');
    }
}

Included are options to

• ask which method deemed it string-y
• exclude methods of string-detection (eg if you dont like .toString())

Here are more tests because I'm a completionist:

out('Edge-case testing')
function test(text, options) {
    var result = duckyString(text, false, options);
    text = duckyString(text, true, options);
    out(result + ' ' + ((result) ? '"' + text + '"' : text));
}
test('');
test(null);
test(undefined);
test(0);
test({length:0});
test({'0':'!', length:'1'});
test({});
test(window);
test(false);
test(['hi']);
test(['\uD83D\uDE07']);
test([['1'], 2, new String(3)]);
test([['1'], 2, new String(3)], {chars:true});

• All negative cases seem to be accounted for
• This should run on browsers >= IE8
• Char arrays with multiple bytes supported on browsers with string iterator support

Output:

Edge-case testing
is ""
null null
null null
to "0"
chars ""
chars "!"
null null
chars ""
to "false"
null null
chars ""
chars "123"
to "1,2,3"

DateTime.Parse

Syntax:

DateTime.Parse(String value)
DateTime.Parse(String value, IFormatProvider provider)
DateTime.Parse(String value, IFormatProvider provider, DateTypeStyles styles)

Example:

string value = "1 January 2019";
CultureInfo provider = new CultureInfo("en-GB");
DateTime.Parse(value, provider, DateTimeStyles.NoCurrentDateDefault););

• Value: string representation of date and time.
• Provider: object which provides culture specific info.
• Styles: formatting options that customize string parsing for some date and time parsing methods. For instance, AllowWhiteSpaces is a value which helps to ignore all spaces present in string while it parse.

It's also worth remembering DateTime is an object that is stored as number internally in the framework, Format only applies to it when you convert it back to string.

• Parsing converting a string to the internal number type.

• Formatting converting the internal numeric value to a readable string.

I recently had an issue where I was trying to convert a DateTime to pass to Linq what I hadn't realised at the time was format is irrelevant when passing DateTime to a Linq Query.

DateTime SearchDate = DateTime.Parse(searchDate);
applicationsUsages = applicationsUsages.Where(x => DbFunctions.TruncateTime(x.dateApplicationSelected) == SearchDate.Date);

There are quite a few answers; some of them are a bit too much theory-heavy. I'll leave why I needed prune once so maybe the need-first/example kind of explanation is useful to someone :)

Problem

I had a folder with about 20 node directories, each having its node_modules directory as expected.

Once you get into any project, you see each ../node_modules/module. But you know how it is. Almost every module has dependencies, so what you are looking at is more like projectN/node_modules/moduleX/node_modules/moduleZ...

I didn't want to drown with a list with the dependency of the dependency of...

Knowing -d n / -depth n, it wouldn't have helped me, as the main/first node_modules directory I wanted of each project was at a different depth, like this:

Projects/MysuperProjectName/project/node_modules/...
Projects/Whatshisname/version3/project/node_modules/...
Projects/project/node_modules/...
Projects/MysuperProjectName/testProject/november2015Copy/project/node_modules/...
[...]

How can I get the first a list of paths ending at the first node_modules and move to the next project to get the same?

Enter -prune

When you add -prune, you'll still have a standard recursive search. Each "path" is analyzed, and every find gets spit out and find keeps digging down like a good chap. But it's the digging down for more node_modules what I didn't want.

So, the difference is that in any of those different paths, -prune will find to stop digging further down that particular avenue when it has found your item. In my case, the node_modules folder.

The difference is that one (forms time-out) has to do authenticating the user and the other( session timeout) has to do with how long cached data is stored on the server. So they are very independent things so one doesn't take precedence over the other.

Use encodeURI()

https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/encodeURI

Escapes pretty much all problematic characters in strings for proper JSON encoding and transit for use in web applications. It's not a perfect validation solution but it catches the low-hanging fruit.

Your script could be stopping, not because of the PHP timeout but because of the timeout in the browser you're using to access the script (ie. Firefox, Chrome, etc). Unfortunately there's seldom an easy way to extend this timeout, and in most browsers you simply can't. An option you have here is to access the script over a terminal. For example, on Windows you would make sure the PHP executable is in your path variable and then I think you execute:

C:\path\to\script> php script.php

Or, if you're using the PHP CGI, I think it's:

C:\path\to\script> php-cgi script.php

Plus, you would also set ini_set('max_execution_time', 0); in your script as others have mentioned. When running a PHP script this way, I'm pretty sure you can use buffer flushing to echo out the script's progress to the terminal periodically if you wish. The biggest issue I think with this method is there's really no way of stopping the script once it's started, other than stopping the entire PHP process or service.

The accepted answer is not always correct. If you configure binary logging on MySQL, you can rollback the database to any previous point you still have a snapshot and binlog for.

7.5 Point-in-Time (Incremental) Recovery Using the Binary Log is a good starting point for learning about this facility.

There are 3 main differences I have found till now. The 3rd one is not so obvious and you may find it interesting. The differences are the same for the express router. That means router.use() and router.get() or other post, put, all, etc methods has also same difference.

1

• app.use(path, callback) will respond to any HTTP request.
• app.get(path, callback) will only respond to GET HTTP request. In the same way, post, put, etc will respond to their corresponding request. app.all() responds to any HTTP request so app.use() and app.all() are the same in this part.

2

• app.use(path, callback) will match the prefix of the request path and responds if any prefix of the request path matches the path parameter. Such as if the path parameter is "/", then it will match "/", "/about", "/users/123" etc.
• app.get(path, callback) Here get will match the whole path. Same for other HTTP requests and app.all(). Such as, if the path parameter is "/", then it will only match "/".

3

next('route') doesn't work on the middleware/callback functions of app.use(). It works only on app.get(), app.all() and other similar function of other HTTP requests.

According to express documentation:

next('route') will work only in middleware functions that were loaded by using the app.METHOD() or router.METHOD() functions.

METHOD is the HTTP method of the request that the middleware function handles (such as GET, PUT, or POST) in lowercase.

From here we will use the keyword METHOD instead of get, post, all, etc.
But what is next('route')?!

Let's see.

next('route')

we see, app.use() or app.METHOD() can take several callback/middleware functions.

From the express documentation:

Middleware functions are functions that have access to the request object (req), the response object (res), and the next middleware function in the application’s request-response cycle. The next middleware function is commonly denoted by a variable named next.

If the current middleware function does not end the request-response cycle, it must call next() to pass control to the next middleware function. Otherwise, the request will be left hanging.

So we see each middleware functions have to either call the next middleware function or end the response. And this is same for app.use() and app.METHOD().

But sometimes in some conditions, you may want to skip all the next callback functions for the current route but also don't want to end the response right now. Because maybe there are other routes which should be matched. So to skip all the callback functions of the current route without ending the response, you can run next('route'). It will skip all the callback functions of the current route and search to match the next routes.

For Example (From express documentation):

app.get('/user/:id', function (req, res, next) {
  // if the user ID is 0, skip to the next route
  if (req.params.id === '0') next('route')
  // otherwise pass the control to the next middleware function in this stack
  else next()
}, function (req, res, next) {
  // send a regular response
  res.send('regular')
})

// handler for the /user/:id path, which sends a special response
app.get('/user/:id', function (req, res, next) {
  res.send('special')
})

See, here in a certain condition(req.params.id === '0') we want to skip the next callback function but also don't want to end the response because there is another route of the same path parameter which will be matched and that route will send a special response. (Yeah, it is valid to use the same path parameter for the same METHOD several times. In such cases, all the routes will be matched until the response ends). So in such cases, we run the next('route') and all the callback function of the current route is skipped. Here if the condition is not met then we call the next callback function.

This next('route') behavior is only possible in the app.METHOD() functions.

Recalling from express documentation:

next('route') will work only in middleware functions that were loaded by using the app.METHOD() or router.METHOD() functions.

Since skipping all callback functions of the current route is not possible in app.use(), we should be careful here. We should only use the middleware functions in app.use() which need not be skipped in any condition. Because we either have to end the response or traverse all the callback functions from beginning to end, we can not skip them at all.

Can you not use the hack you've already shown, and then use an IE7 and below hack to override it?

Yes in SQl <> is the same as != which is not equal.....excepts for NULLS of course, in that case you need to use IS NULL or IS NOT NULL

Updating to use tibble()

You can pass a named vector of length greater than 1 to the by argument of left_join():

library(dplyr)

d1 <- tibble(
  x = letters[1:3],
  y = LETTERS[1:3],
  a = rnorm(3)
  )

d2 <- tibble(
  x2 = letters[3:1],
  y2 = LETTERS[3:1],
  b = rnorm(3)
  )

left_join(d1, d2, by = c("x" = "x2", "y" = "y2"))

You just need to define in your bean where you need a different scope than default singleton scope except prototype. For example:

<bean id="shoppingCart" 
   class="com.xxxxx.xxxx.ShoppingCartBean" scope="session">
   <aop:scoped-proxy/> 
</bean>

PTBNL's Answer is quite perfect for me. I make a little more for Windows user.

One technology you should consider is SQLJ - a way to embed SQL statements directly in Java. As a simple example, you might have the following in a file called TestQueries.sqlj:

public class TestQueries
{
    public String getUsername(int id)
    {
        String username;
        #sql
        {
            select username into :username
            from users
            where pkey = :id
        };
        return username;
    }
}

There is an additional precompile step which takes your .sqlj files and translates them into pure Java - in short, it looks for the special blocks delimited with

#sql
{
    ...
}

and turns them into JDBC calls. There are several key benefits to using SQLJ:

• completely abstracts away the JDBC layer - programmers only need to think about Java and SQL
• the translator can be made to check your queries for syntax etc. against the database at compile time
• ability to directly bind Java variables in queries using the ":" prefix

There are implementations of the translator around for most of the major database vendors, so you should be able to find everything you need easily.

var var1 = 1, var2 = 1, var3 = 1;

In this case var keyword is applicable to all the three variables.

var var1 = 1,
    var2 = 1,
    var3 = 1;

which is not equivalent to this:

var var1 = var2 = var3 = 1;

In this case behind the screens var keyword is only applicable to var1 due to variable hoisting and rest of the expression is evaluated normally so the variables var2, var3 are becoming globals

Javascript treats this code in this order:

/*
var 1 is local to the particular scope because of var keyword
var2 and var3 will become globals because they've used without var keyword
*/

var var1;   //only variable declarations will be hoisted.

var1= var2= var3 = 1; 

button.setVisibility(button.getVisibility() == View.VISIBLE ? View.GONE : View.VISIBLE);

Makes it visible if invisible and invisible if visible

You can't extend Enum as it's a static class. You can only extend instances of a type. With this in mind, you're going to have to create a static method yourself to do this; the following should work when combined with your existing method GetDescription:

public static class EnumHelper
{
    public static T GetEnumFromString<T>(string value)
    {
        if (Enum.IsDefined(typeof(T), value))
        {
            return (T)Enum.Parse(typeof(T), value, true);
        }
        else
        {
            string[] enumNames = Enum.GetNames(typeof(T));
            foreach (string enumName in enumNames)
            {  
                object e = Enum.Parse(typeof(T), enumName);
                if (value == GetDescription((Enum)e))
                {
                    return (T)e;
                }
            }
        }
        throw new ArgumentException("The value '" + value 
            + "' does not match a valid enum name or description.");
    }
}

And the usage of it would be something like this:

Animal giantPanda = EnumHelper.GetEnumFromString<Animal>("Giant Panda");

I found this works just fine and the browser handles it in firefox. I have not checked IE...

<script>window.location='url'</script>

1. Go to the line, and first press esc, and then Shift + v.

(This would have highlighted the line)

2. press d

(The line is now deleted)

3. Go to the location, where you wanted to paste the line, and hit p.

In a nutshell,

Esc -> Shift + v -> d -> p

ShortcutBadger is a library that adds an abstraction layer over the device brand and current launcher and offers a great result. Works with LG, Sony, Samsung, HTC and other custom Launchers.

It even has a way to display Badge Count in Pure Android devices desktop.

Updating the Badge Count in the application icon is as easy as calling:

int badgeCount = 1;
ShortcutBadger.applyCount(context, badgeCount);

It includes a demo application that allows you to test its behavior.

If you are doing form validation such as

type="submit" onsubmit="return validateForm(this)"

validateForm = function(form) {
if ($('input#company').val() === "" || $('input#company').val() === "Company")  {
        $('input#company').val("Company").css('color','red'); finalReturn = false; 
        $('input#company').on('mouseover',(function() { 
            $('input#company').val("").css('color','black'); 
            $('input#company').off('mouseover');
            finalReturn = true; 
        }));
    } 

    return finalReturn; 
}

Double check you are returning true. This seems simple but I had

var finalReturn = false;

When the form was correct it was not being corrected by validateForm and so not being submitted as finalReturn was still initialized to false instead of true. By the way, above code works nicely with address, city, state and so on.

There is no bidirectional map in the Java Standard API. Either you can maintain two maps yourself or use the BidiMap from Apache Collections.

Must it be an Eclipse plug-in? I use doxygen, just supply your code folder, it handles the rest.

CoffeeScript has no ternary operator. That's what the docs say.

You can still use a syntax like

a = true then 5 else 10

It's way much clearer.

I prefer to use the ngModel and ngChange directives when dealing with checkboxes. ngModel allows you to bind the checked/unchecked state of the checkbox to a property on the entity:

<input type="checkbox" ng-model="entity.isChecked">

Whenever the user checks or unchecks the checkbox the entity.isChecked value will change too.

If this is all you need then you don't even need the ngClick or ngChange directives. Since you have the "Check All" checkbox, you obviously need to do more than just set the value of the property when someone checks a checkbox.

When using ngModel with a checkbox, it's best to use ngChange rather than ngClick for handling checked and unchecked events. ngChange is made for just this kind of scenario. It makes use of the ngModelController for data-binding (it adds a listener to the ngModelController's $viewChangeListeners array. The listeners in this array get called after the model value has been set, avoiding this problem).

<input type="checkbox" ng-model="entity.isChecked" ng-change="selectEntity()">

... and in the controller ...

var model = {};
$scope.model = model;

// This property is bound to the checkbox in the table header
model.allItemsSelected = false;

// Fired when an entity in the table is checked
$scope.selectEntity = function () {
    // If any entity is not checked, then uncheck the "allItemsSelected" checkbox
    for (var i = 0; i < model.entities.length; i++) {
        if (!model.entities[i].isChecked) {
            model.allItemsSelected = false;
            return;
        }
    }

    // ... otherwise ensure that the "allItemsSelected" checkbox is checked
    model.allItemsSelected = true;
};

Similarly, the "Check All" checkbox in the header:

<th>
    <input type="checkbox" ng-model="model.allItemsSelected" ng-change="selectAll()">
</th>

... and ...

// Fired when the checkbox in the table header is checked
$scope.selectAll = function () {
    // Loop through all the entities and set their isChecked property
    for (var i = 0; i < model.entities.length; i++) {
        model.entities[i].isChecked = model.allItemsSelected;
    }
};

CSS

What is the best way to... add a CSS class to the <tr> containing the entity to reflect its selected state?

If you use the ngModel approach for the data-binding, all you need to do is add the ngClass directive to the <tr> element to dynamically add or remove the class whenever the entity property changes:

<tr ng-repeat="entity in model.entities" ng-class="{selected: entity.isChecked}">

See the full Plunker here.

The CSS property that can be used is:

pointer-events:none

!IMPORTANT Keep in mind that this property is not supported by Opera Mini and IE 10 and below (inclusive). Another solution is needed for these browsers.

jQuery METHOD If you want to disable it via script and not CSS property, these can help you out: If you're using jQuery versions 1.4.3+:

$('selector').click(false);

If not:

$('selector').click(function(){return false;});

• Referenced from : jquery - disable click

You can re-enable clicks with pointer-events: auto; (Documentation)

Note that pointer-events overrides the cursor property, so if you want the cursor to be something other than the standard , your css should be place after pointer-events.

It is strange, that no one yet has suggested the most robust way of closing a feature branches... You can just combine merge commit with --close-branch flag (i.e. commit modified files and close the branch simultaneously):

hg up feature-x
hg merge default
hg ci -m "Merge feature-x and close branch" --close-branch
hg branch default -f

So, that is all. No one extra head on revgraph. No extra commit.

Value is not a valid attribute of DIV

try this

var divElement = document.getElementById('demo');
alert( divElement .getAttribute('value'));

If i is the int, then

char c = i;

makes it a char. You might want to add a check that the value is <128 if it comes from an untrusted source. This is best done with isascii from <ctype.h>, if available on your system (see @Steve Jessop's comment to this answer).

yourTextView.setGravity(Gravity.CENTER);

string s2 = s1.Replace(",", ",\n");

myArrayOfMatrices = zeros(unknown,500,800);

If you're running out of memory throw more RAM in your system, and make sure you're running a 64 bit OS. Also try reducing your precision (do you really need doubles or can you get by with singles?):

myArrayOfMatrices = zeros(unknown,500,800,'single');

To append to that array try:

myArrayOfMatrices(unknown+1,:,:) = zeros(500,800);

Firebug Lite supports to inspect HTML elements, computed CSS style, and a lot more. Since it's pure JavaScript, it works in many different browsers. Just include the script in your source, or add the bookmarklet to your bookmark bar to include it on any page with a single click.

I had similar issue, I was able to solve it using -U option along with mvn command as

mvn clean install -U

This worked for me, hope it helps.

Reference: Mastering Regular Expressions (Jeffrey E.F. Friedl) - O'Reilly

\b is equivalent to (?<!\w)(?=\w)|(?<=\w)(?!\w)

I encountered a similar error message. I was able to fix it without enabling remote errors.

In Report Builder 3.0, when I used the Run button to run the report, an error alert appeared, saying

An error has occurred during report processing. (rsProcessingAborted)
[OK] [Details...]

Pressing the details button gave me a text box where I saw this text:

For more information about this error navigate to the report server
on the local server machine, or enable remote errors
----------------------------
Query execution failed for dataset 'DataSet1'. (rsErrorExecutingCommand)

I was confused and frustrated, because my report did not have a dataset named 'DataSet1'. I even opened the .rdl file in a text editor to be sure. After a while, I noticed that there was more text in the text box below what I could read. The full error message was:

For more information about this error navigate to the report server
on the local server machine, or enable remote errors
----------------------------
Query execution failed for dataset 'DataSet1'. (rsErrorExecutingCommand)

----------------------------
The execution failed for the shared data set 'CustomerDetailsDataSet'.  
(rsDataSetExecutionError)
----------------------------
An error has occurred during report processing. (rsProcessingAborted)

I did have a shared dataset named 'CustomerDetailsDataSet'. I opened the query (which was a full SQL query entered in text mode) in SQL Server Management Studio, and ran it there. I got error messages which clearly pointed to a certain table, where a column I had been using had been renamed and changed.

From that point, it was straightforward to modify my query so that it worked with the new column, then paste that modification into the shared dataset 'CustomerDetailsDataSet', and then nudge the report in Report Builder to recognise the change to the shared dataset.

After this fix, my reports no longer triggered this error.

1. exec is not an expression: a statement in Python 2.x, and a function in Python 3.x. It compiles and immediately evaluates a statement or set of statement contained in a string. Example:

    exec('print(5)')           # prints 5.
    # exec 'print 5'     if you use Python 2.x, nor the exec neither the print is a function there
    exec('print(5)\nprint(6)')  # prints 5{newline}6.
    exec('if True: print(6)')  # prints 6.
    exec('5')                 # does nothing and returns nothing.
   

2. eval is a built-in function (not a statement), which evaluates an expression and returns the value that expression produces. Example:

    x = eval('5')              # x <- 5
    x = eval('%d + 6' % x)     # x <- 11
    x = eval('abs(%d)' % -100) # x <- 100
    x = eval('x = 5')          # INVALID; assignment is not an expression.
    x = eval('if 1: x = 4')    # INVALID; if is a statement, not an expression.
   

3. compile is a lower level version of exec and eval. It does not execute or evaluate your statements or expressions, but returns a code object that can do it. The modes are as follows:

4. compile(string, '', 'eval') returns the code object that would have been executed had you done eval(string). Note that you cannot use statements in this mode; only a (single) expression is valid.

5. compile(string, '', 'exec') returns the code object that would have been executed had you done exec(string). You can use any number of statements here.

6. compile(string, '', 'single') is like the exec mode but expects exactly one expression/statement, eg compile('a=1 if 1 else 3', 'myf', mode='single')

VS2019 - ASP.NET Forms In my case was Tools - Options - Windows Forms Designer - "Optimized Code Generation" <- to false

If you want to use @Html.EditorFor() you have to use jQuery ui and update your Asp.net Mvc to 5.2.6.0 with NuGet Package Manager.

@Html.EditorFor(m => m.EntryDate, new { htmlAttributes = new { @class = "datepicker" } })

@section Scripts {

@Scripts.Render("~/bundles/jqueryval")

<script>

    $(document).ready(function(){

      $('.datepicker').datepicker();

     });

</script>

}

To Get The Data From the App.config

Keeping in mind you have to:

1. Added to the References -> System.Configuration
2. and also added this using statement -> using System.Configuration;

Just Simply do this

string value1 = ConfigurationManager.AppSettings["Value1"];

Alternatively, you can achieve this in one line, if you don't want to add using System.Configuration; explicitly.

string value1 = System.Configuration.ConfigurationManager.AppSettings["Value1"]

Basically, == compares if two objects have the same reference on the heap, so unless two references are linked to the same object, this comparison will be false.

equals() is a method inherited from Object class. This method by default compares if two objects have the same referece. It means:

object1.equals(object2) <=> object1 == object2

However, if you want to establish equality between two objects of the same class you should override this method. It is also very important to override the method hashCode() if you have overriden equals().

Implement hashCode() when establishing equality is part of the Java Object Contract. If you are working with collections, and you haven't implemented hashCode(), Strange Bad Things could happen:

HashMap<Cat, String> cats = new HashMap<>();
Cat cat = new Cat("molly");
cats.put(cat, "This is a cool cat");
System.out.println(cats.get(new Cat("molly"));

null will be printed after executing the previous code if you haven't implemented hashCode().

You can use Vue.nextTick

addToBasket: function(){
                item = this.photo;
                this.$http.post('/api/buy/addToBasket', item);
                this.basketAddSuccess = true;
                Vue.nextTick(() =>{
                    this.basketAddSuccess = false;
                });
            }

This has changed for android 4.4.2. .. you should look in the repository file and download https://dl-ssl.google.com/android/repository/repository-10.xml

1. android-sdk_r20.0.1-windows.zip ( I think that is actually windows specific tools)
2. android-19_r03.zip for all platform ( actual api) and store under platforms in #1

In manual install dir structure should look like

Now you have to..

1. download win SDK helper ( avd/SDK magr): https://dl.google.com/android/android-sdk_r20.0.1-windows.zip
2. actual sdk api https://dl-ssl.google.com/android/repository/android-20_r01.zip
3. samples https://dl-ssl.google.com/android/repository/samples-19_r05.zip
4. images : https://dl-ssl.google.com/android/repository/sys-img/x86/sys-img.xml e.g. https://dl-ssl.google.com/android/repository/sysimg_armv7a-18_r02.zip extract in : “Platforms > Android-4.4.2>"
5. platform-tools: https://dl-ssl.google.com/android/repository/platform-tools_r19.0.1-windows.zip
6. build-tools: create folder (build-tools at main sdk level) https://dl-ssl.google.com/android/repository/build-tools_r17-windows.zip
7. copy aapt.exe, aidl.exe and dr.bat to platform-tools folder.
8. you may download tools as well same way
9. source: https://dl-ssl.google.com/android/repository/sources-19_r02.zip

At this point you should have a working android installation.

Authentication is a property of a thread in server environment in the same way as it is a property of a process in OS. Having a bean instance for accessing authentication information would be inconvenient configuration and wiring overhead without any benefit.

Regarding test authentication there are several ways how you can make your life easier. My favourite is to make a custom annotation @Authenticated and test execution listener, which manages it. Check DirtiesContextTestExecutionListener for inspiration.

If these all answers are not working then You can simply use multiple mail function for multiple recipient.

$email_to1 = "[email protected]";
$email_to2 = "[email protected]";

mail($email_to1, $email_subject, $email_message, $headers);  
mail($email_to2, $email_subject, $email_message, $headers);  

base64 encode/decode example:

import base64

mystr = 'O João mordeu o cão!'

# Encode
mystr_encoded = base64.b64encode(mystr.encode('utf-8'))
# b'TyBKb8OjbyBtb3JkZXUgbyBjw6NvIQ=='

# Decode
mystr_encoded = base64.b64decode(mystr_encoded).decode('utf-8')
# 'O João mordeu o cão!'

The code marked as the solution did not work for me. This was my solution.

MSYS has not been updated a long time, MSYS2 is more active, you can download from MSYS2, it has both mingw and cygwin fork package.

To install the MinGW-w64 toolchain (Reference):

1. Open MSYS2 shell from start menu
2. Run pacman -Sy pacman to update the package database
3. Re-open the shell, run pacman -Syu to update the package database and core system packages
4. Re-open the shell, run pacman -Su to update the rest
5. Install compiler:
   • For 32-bit target, run pacman -S mingw-w64-i686-toolchain
   • For 64-bit target, run pacman -S mingw-w64-x86_64-toolchain
6. Select which package to install, default is all
7. You may also need make, run pacman -S make

I extends the SimpleJpaRepository:

public class ExtendedRepositoryImpl<T extends EntityBean> extends SimpleJpaRepository<T, Long>
    implements ExtendedRepository<T> {

    private final JpaEntityInformation<T, ?> entityInformation;

    private final EntityManager em;

    public ExtendedRepositoryImpl(final JpaEntityInformation<T, ?> entityInformation,
                                                      final EntityManager entityManager) {
       super(entityInformation, entityManager);
       this.entityInformation = entityInformation;
       this.em = entityManager;
    }
}

and adds this class to @EnableJpaRepositoryries repositoryBaseClass.

In addition set the proxy for the command line session Open a command line where you might want to run your script

netsh winhttp set proxy YourProxySERVER:yourProxyPORT

run your script in that terminal.

Using Guava (r07) you can do this:

for(char c : Lists.charactersOf(someString)) { ... }

This has the convenience of using foreach while not copying the string to a new array. Lists.charactersOf returns a view of the string as a List.

Try this:

schtasks /change /ENABLE /tn "Auto Restart" /s mycomutername /u mycomputername\username/p mypassowrd

For the same issue on Windows7

You will see an error like this if your environment variables/ system variables are incorrectly set:

Fatal Python error: Py_Initialize: unable to load the file system codec
ImportError: No module named 'encodings'

Current thread 0x00001db4 (most recent call first):

Fixing this is really simple:

1. When you download Python3.x version, and run the .exe file, it gives you an option to customize where in your system you want to install Python. For example, I chose this location: C:\Program Files\Python36

2. Then open system properties and go to "Advanced" tab (Or you can simply do this: Go to Start > Search for "environment variables" > Click on "Edit the system environment variables".) Under the "Advanced" tab, look for "Environment Variables" and click it. Another window with name "Environment Variables" will pop up.

3. Now make sure your user variables have the correct Python path listed in "Path Variable". In my example here, you should see C:\Program Files\Python36. If you do not find it there, add it, by selecting Path Variable field and clicking Edit.

4. Last step is to double-check PYTHONHOME and PYTHONPATH fields under System Variables in the same window. You should see the same path as described above. If not add it there too.

Then click OK and go back to CMD terminal, and try checking for python. The issue should now be resolved. It worked for me.

The ternary operator is just a shorthand for and if/else block. Your working code does not have an else condition, so is not suitable for this.

The following example will work:

echo empty($address['street2']) ? 'empty' : 'not empty';

Try a different protocol. git:// may have problems from your firewall, for example; try a git clone with https: instead.

This is a segfault due to following a null pointer trying to find code to run (that is, during an instruction fetch).

If this were a program, not a shared library

Run addr2line -e yourSegfaultingProgram 00007f9bebcca90d (and repeat for the other instruction pointer values given) to see where the error is happening. Better, get a debug-instrumented build, and reproduce the problem under a debugger such as gdb.

Since it's a shared library

You're hosed, unfortunately; it's not possible to know where the libraries were placed in memory by the dynamic linker after-the-fact. Reproduce the problem under gdb.

What the error means

Here's the breakdown of the fields:

• address (after the at) - the location in memory the code is trying to access (it's likely that 10 and 11 are offsets from a pointer we expect to be set to a valid value but which is instead pointing to 0)
• ip - instruction pointer, ie. where the code which is trying to do this lives
• sp - stack pointer

• error - An error code for page faults; see below for what this means on x86.

  /*
   * Page fault error code bits:
   *
   *   bit 0 ==    0: no page found       1: protection fault
   *   bit 1 ==    0: read access         1: write access
   *   bit 2 ==    0: kernel-mode access  1: user-mode access
   *   bit 3 ==                           1: use of reserved bit detected
   *   bit 4 ==                           1: fault was an instruction fetch

It's called spread attributes and its aim is to make the passing of props easier.

Let us imagine that you have a component that accepts N number of properties. Passing these down can be tedious and unwieldy if the number grows.

<Component x={} y={} z={} />

Thus instead you do this, wrap them up in an object and use the spread notation

var props = { x: 1, y: 1, z:1 };
<Component {...props} />

which will unpack it into the props on your component, i.e., you "never" use {... props} inside your render() function, only when you pass the props down to another component. Use your unpacked props as normal this.props.x.

Why be easy when it can be complicated? Why use third-party applications like netdom.exe when correct interogations is the way? Try 2 interogations:

wmic computersystem where caption='%computername%' get caption, UserName, Domain /format:value

wmic computersystem where "caption like '%%%computername%%%'" get caption, UserName, Domain /format:value

or in a batch file use loop

for /f "tokens=2 delims==" %%i in ('wmic computersystem where "Caption like '%%%currentname%%%'" get UserName /format:value') do (echo. UserName- %%i)

you have an extra "}" in each object, you may write the json string like this:

A ListView is a specialized ListBox (that is, it inherits from ListBox). It allows you to specify different views rather than a straight list. You can either roll your own view, or use GridView (think explorer-like "details view"). It's basically the multi-column listbox, the cousin of windows form's listview.

If you don't need the additional capabilities of ListView, you can certainly use ListBox if you're simply showing a list of items (Even if the template is complex).

To replace only single quotes, use this simple statement:

$string = str_replace("'", "\\'", $string);

As far as I am aware you have to use javascript to travel up the dom.

Something like this:

$("textarea:focus").parent().attr("border", "thin solid black");

you'll need the jQuery libraries loaded as well.

DOUBLE columns are not the same as DECIMAL columns, and you will get in trouble if you use DOUBLE columns for financial data.

DOUBLE is actually just a double precision (64 bit instead of 32 bit) version of FLOAT. Floating point numbers are approximate representations of real numbers and they are not exact. In fact, simple numbers like 0.01 do not have an exact representation in FLOAT or DOUBLE types.

DECIMAL columns are exact representations, but they take up a lot more space for a much smaller range of possible numbers. To create a column capable of holding values from 0.0001 to 99.9999 like you asked you would need the following statement

CREATE TABLE your_table
(
    your_column DECIMAL(6,4) NOT NULL
);

The column definition follows the format DECIMAL(M, D) where M is the maximum number of digits (the precision) and D is the number of digits to the right of the decimal point (the scale).

This means that the previous command creates a column that accepts values from -99.9999 to 99.9999. You may also create an UNSIGNED DECIMAL column, ranging from 0.0000 to 99.9999.

For more information on MySQL DECIMAL the official docs are always a great resource.

Bear in mind that all of this information is true for versions of MySQL 5.0.3 and greater. If you are using previous versions, you really should upgrade.

git log $(git log --pretty=format:%H|tail -1)

Here's a way of doing it using dom4j:

Imports:

import org.dom4j.Document;  
import org.dom4j.DocumentHelper;  
import org.dom4j.io.OutputFormat;  
import org.dom4j.io.XMLWriter;

Code:

String xml = "<your xml='here'/>";  
Document doc = DocumentHelper.parseText(xml);  
StringWriter sw = new StringWriter();  
OutputFormat format = OutputFormat.createPrettyPrint();  
XMLWriter xw = new XMLWriter(sw, format);  
xw.write(doc);  
String result = sw.toString();

when you declare int array[2]; you reserve 2 memory spaces of 4 bytes each(32bit program). if you type array[4] in your code it still corresponds to a valid call but only at run time will it throw an unhandled exception. C++ uses manual memory management. This is actually a security flaw that was used for hacking programs

this can help understanding:

int * somepointer;

somepointer[0]=somepointer[5];

1. Inside your lib file

2. Create a folder called colors.

3. Inside the colors folder create a dart file and name it color.

4. Paste this code inside it

   const MaterialColor primaryOrange = MaterialColor(
       _orangePrimaryValue,
       <int, Color>{
           50: Color(0xFFFF9480),
           100: Color(0xFFFF9480),
           200: Color(0xFFFF9480),
           300: Color(0xFFFF9480),
           400: Color(0xFFFF9480),
           500: Color(0xFFFF9480),
           600: Color(0xFFFF9480),
           700: Color(0xFFFF9480),
           800: Color(0xFFFF9480),
           900: Color(0xFFFF9480),
       },
   );
   const int _orangePrimaryValue = 0xFFFF9480;
   

5. Go to your main.dart file and place this code in your theme

   theme:ThemeData(
       primarySwatch: primaryOrange,
   ),
   

6. Import the color folder in your main.dart like this import 'colors/colors.dart';

The below query will display all the tables and corresponding column count in a database schema

SELECT Table_Name, count(*) as [No.of Columns]
FROM INFORMATION_SCHEMA.COLUMNS
WHERE table_schema = 'dbo' -- schema name
group by table_name

I solve the problem. So simple. Syntax error.

• App\Service

But I also want to know how to pass a function with parameters to view....

you call function on page load time but not call on button event, you will need to call function onclick event, you may add event inline element style or event bining

 function Choice(elem) {_x000D_
   var box = document.getElementById("box");_x000D_
   if (elem.id == "no") {_x000D_
     box.style.backgroundColor = "red";_x000D_
   } else if (elem.id == "yes") {_x000D_
     box.style.backgroundColor = "green";_x000D_
   } else {_x000D_
     box.style.backgroundColor = "purple";_x000D_
   };_x000D_
 };

<div id="box">dd</div>_x000D_
<button id="yes" onclick="Choice(this);">yes</button>_x000D_
<button id="no" onclick="Choice(this);">no</button>_x000D_
<button id="other" onclick="Choice(this);">other</button>

or event binding,

window.onload = function() {_x000D_
  var box = document.getElementById("box");_x000D_
  document.getElementById("yes").onclick = function() {_x000D_
    box.style.backgroundColor = "red";_x000D_
  }_x000D_
  document.getElementById("no").onclick = function() {_x000D_
    box.style.backgroundColor = "green";_x000D_
  }_x000D_
}

<div id="box">dd</div>_x000D_
<button id="yes">yes</button>_x000D_
<button id="no">no</button>

VSCode will never refresh the file if you have changes in that file that are not saved to disk. However, if the file is open and does not have changes, it will replace with the changes on disk, that is true.

There is currently no way to disable this behaviour.

There's now an easy way to do this using dplyr.

First of all, a warning: what follows is strictly in the realm of ugly, undocumented hacks. Do not rely on this working - even if it works for you now, it may stop working tomorrow, with any minor or major .NET update.

You can use the information in this article on CLR internals MSDN Magazine Issue 2005 May - Drill Into .NET Framework Internals to See How the CLR Creates Runtime Objects - last I checked, it was still applicable. Here's how this is done (it retrieves the internal "Basic Instance Size" field via TypeHandle of the type).

object obj = new List<int>(); // whatever you want to get the size of
RuntimeTypeHandle th = obj.GetType().TypeHandle;
int size = *(*(int**)&th + 1);
Console.WriteLine(size);

This works on 3.5 SP1 32-bit. I'm not sure if field sizes are the same on 64-bit - you might have to adjust the types and/or offsets if they are not.

This will work for all "normal" types, for which all instances have the same, well-defined types. Those for which this isn't true are arrays and strings for sure, and I believe also StringBuilder. For them you'll have add the size of all contained elements to their base instance size.

create alert, tested in xcode 9

let alert = UIAlertController(title: "title", message: "message", preferredStyle: UIAlertControllerStyle.alert)
alert.addAction(UIAlertAction(title: "Ok", style: UIAlertActionStyle.default, handler: self.finishAlert))
self.present(alert, animated: true, completion: nil)

and the function

func finishAlert(alert: UIAlertAction!)
{
}

I saw this post at least twice, because the accepted answer is hard to remeber for me(I rarely use z or j flags and they are seems not platform independant).

The standard never says clearly the exact data length of size_t, so I suggest you should first check the length size_t on your platform then select one of them:

if sizeof(size_t) == 4 use PRIu32
if sizeof(size_t) == 8 use PRIu64

And I suggest using stdint types instead of raw data types for consistancy.

It can be done in the following two ways:

• select floor(desired_field_value) from table
• select round(desired_field_value-0.5) from table

The 2nd-way explanation: Assume 12345.7344 integer. So, 12345.7344 - 0.5 = 12345.2344 and rounding off the result will be 12345.

Use:

/category[@name='Sport' and author/text()[1]='James Small']

or use:

/category[@name='Sport' and author[starts-with(.,'James Small')]]

It is a good rule to try to avoid using the // pseudo-operator whenever possible, because its evaluation can typically be very slow.

Also:

./somename

is equivalent to:

somename

so it is recommended to use the latter.

Baron Schwartz blogs that due to race conditions, this 'check before write' is a bad practice. He advocates a try/catch pattern with a reconnect in the catch. Here is the pseudo code he recommends:

function query_database(connection, sql, retries=1)
   while true
      try
         result=connection.execute(sql)
         return result
      catch InactiveConnectionException e
         if retries > 0 then
            retries = retries - 1
            connection.reconnect()
         else
            throw e
         end
      end
   end
end

The technical difference according to two features:
1. Where the "work" is done
2. What is being transferred to/from the server

Web app
1. The "work" is done at the browser (JavaScript)
2. Data is being transferred from/to the server
In comparison: Faster

Website
1. The "work" (most of it) is done at the server
2. Rendered pages (data + UI) are being transferred from the server
In comparison: Easier SEO

With C# 8 onwards you can make it even more concise with the new switch. And with the use of discard option _ you can avoid creating innecesary variables when you don't need them, like this:

        return document switch {
            Invoice _ => "Is Invoice",
            ShippingList _ => "Is Shipping List",
            _ => "Unknown"
        };

Invoice and ShippingList are classes and document is an object that can be either of them.

You have your arguments to the remote add command reversed:

git remote add <NAME> <PATH>

So:

git remote add bak /home/sas/dev/apps/smx/repo/bak/ontologybackend/.git

See git remote --help for more information.

could it be that you forgot to load it in the document ready function?

$(document).ready(function () {

    //your jQuery function
});

This Can be Done by Style Property.

<!DOCTYPE html>
<html>
<head>
<style> 
#main {

  display: flex;
}

#main div {
  flex-grow: 0;
  flex-shrink: 0;
  flex-basis: 40px;
}
</style>
</head>
<body>

<div id="main">
  <div style="background-color:coral;">Red DIV</div>
  <div style="background-color:lightblue;" id="myBlueDiv">Blue DIV</div>
</div>

</body>
</html>

Its Result will be :

Enjoy... Please Note: This works in Higher version of CSS (>3.0).

date +%s%N returns the number of seconds + current nanoseconds.

Therefore, echo $(($(date +%s%N)/1000000)) is what you need.

Example:

$ echo $(($(date +%s%N)/1000000))
1535546718115

date +%s returns the number of seconds since the epoch, if that's useful.

npm install from git bash did work for me. After rebooting PC.

If you are using Maven, add the below config in your pom.xml:

<build>
    <testResources>
                <testResource>
                    <directory>src/main/webapp</directory>
                </testResource>
    </testResources>
</build>

With this config, you will be able to access xml files in WEB-INF folder. From Maven POM Reference: The testResources element block contains testResource elements. Their definitions are similar to resource elements, but are naturally used during test phases.

I know you're interested in Integer numbers so I won't re answer that but if you ever wanted to check for Floating Point numbers you could do this.

function isFloat( x )
{
    return ( typeof x === "number" && Math.abs( x % 1 ) > 0);
}

Note: This MAY treat numbers ending in .0 (or any logically equivalent number of 0's) as an INTEGER. It actually needs a floating point precision error to occur to detect the floating point values in that case.

Ex.

alert(isFloat(5.2));   //returns true
alert(isFloat(5));     //returns false
alert(isFloat(5.0));   //return could be either true or false

This should work:

SELECT field,CONVERT(SUBSTRING_INDEX(field,'-',-1),UNSIGNED INTEGER) AS num
FROM table
ORDER BY num;

Apps targeting Android Q - API 29 by default are given a filtered view into external storage. A quick fix for that is to add this code in the AndroidManifest.xml:

<manifest ... >
    <!-- This attribute is "false" by default on apps targeting Android Q. -->
    <application android:requestLegacyExternalStorage="true" ... >
     ...
    </application>
</manifest>

Read more about it here: https://developer.android.com/training/data-storage/compatibility

For me, Abhi's solution works great up to Api level 27.

But it seems that from Api level 28 and upwards, onItemSelected() is not called when listener is set, which means onItemSelected() is never called.

Therefore, I added a short if-statement to check Api level:

public void onItemSelected(AdapterView<?> parent, View arg1, int pos,long id) {

            if(Build.VERSION.SDK_INT >= 28){ //onItemSelected() doesn't seem to be called when listener is set on Api 28+
                check = 1;
            }

            if(++check > 1) {
                //Do your action here
            }
        }

I think that's quite weird and I'm not sure wether others also have this problem, but in my case it worked well.

var datatable_jquery_script = document.createElement("script");
datatable_jquery_script.src = "vendor/datatables/jquery.dataTables.min.js";
document.body.appendChild(datatable_jquery_script);
setTimeout(function(){
    var datatable_bootstrap_script = document.createElement("script");
    datatable_bootstrap_script.src = "vendor/datatables/dataTables.bootstrap4.min.js";
    document.body.appendChild(datatable_bootstrap_script);
},100);

I used setTimeOut to make sure datatables.min.js loads first. I inspected the waterfall loading of each, bootstrap4.min.js always loads first.

I was also looking for the relative path version, this works OK. Note when run (Spyder 3.6) you will see (unicode error) 'unicodeescape' codec can't decode bytes at the closing triple quote. Remove the offending comment lines 14 and 15 and adjust the file names and location for your environment and check for indentation.

If it is inline, the browser should attempt to render it within the browser window. If it cannot, it will resort to an external program, prompting the user.

With attachment, it will immediately go to the user, and not try to load it in the browser, whether it can or not.

Try run this command it will create a *_limits.conf file under /etc/security/limits.d

echo "* soft nofile 102400" > /etc/security/limits.d/*_limits.conf && echo "* hard nofile 102400" >> /etc/security/limits.d/*_limits.conf

Just exit from terminal and login again and verify by ulimit -n it will set for * users

Write a Mock object and use them just for testing. They usually are very very very minimal (inherit from the abstract class) and not more.Then, in your Unit Test you can call the abstract method you want to test.

You should test abstract class that contain some logic like all other classes you have.

You can find the aspnet_regiis in the following directory:

C:\Windows\Microsoft.NET\Framework64\v4.0.30319

Go to the directory and run the command form there. I guess the path is missing in your PATH variable.

I used to write my own error logging until I discovered ELMAH. I've never been able to get the emailing part down quite as perfectly as ELMAH does.

Let us call the sample code posted here the redirector and the other program the redirected. If it were me then I would probably write a test redirected program that can be used to duplicate the problem.

So I did. For test data I used the ECMA-334 C# Language Specificationv PDF; it is about 5MB. The following is the important part of that.

StreamReader stream = null;
try { stream = new StreamReader(Path); }
catch (Exception ex)
{
    Console.Error.WriteLine("Input open error: " + ex.Message);
    return;
}
Console.SetIn(stream);
int datasize = 0;
try
{
    string record = Console.ReadLine();
    while (record != null)
    {
        datasize += record.Length + 2;
        record = Console.ReadLine();
        Console.WriteLine(record);
    }
}
catch (Exception ex)
{
    Console.Error.WriteLine($"Error: {ex.Message}");
    return;
}

The datasize value does not match the actual file size but that does not matter. It is not clear if a PDF file always uses both CR and LF at the end of lines but that does not matter for this. You can use any other large text file to test with.

Using that the sample redirector code hangs when I write the large amount of data but not when I write a small amount.

I tried very much to somehow trace the execution of that code and I could not. I commented out the lines of the redirected program that disabled creation of a console for the redirected program to try to get a separate console window but I could not.

Then I found How to start a console app in a new window, the parent’s window, or no window. So apparently we cannot (easily) have a separate console when one console program starts another console program without ShellExecute and since ShellExecute does not support redirection we must share a console, even if we specify no window for the other process.

I assume that if the redirected program fills up a buffer somewhere then it must wait for the data to be read and if at that point no data is read by the redirector then it is a deadlock.

The solution is to not use ReadToEnd and to read the data while the data is being written but it is not necessary to use asynchronous reads. The solution can be quite simple. The following works for me with the 5 MB PDF.

ProcessStartInfo info = new ProcessStartInfo(TheProgram);
info.CreateNoWindow = true;
info.WindowStyle = System.Diagnostics.ProcessWindowStyle.Hidden;
info.RedirectStandardOutput = true;
info.UseShellExecute = false;
Process p = Process.Start(info);
string record = p.StandardOutput.ReadLine();
while (record != null)
{
    Console.WriteLine(record);
    record = p.StandardOutput.ReadLine();
}
p.WaitForExit();

Another possibility is to use a GUI program to do the redirection. The preceding code works in a WPF application except with obvious modifications.
