It's not necessary to use nested form groups and a custom ErrorStateMatcher for confirm password validation. These steps were added to facilitate coordination between the password fields, but you can do that without all the overhead.

Here is an example:

this.registrationForm = this.fb.group({
  username: ['', Validators.required],
  email: ['', [Validators.required, Validators.email]],
  password1: ['', [Validators.required, (control) => this.validatePasswords(control, 'password1') ] ],
  password2: ['', [Validators.required, (control) => this.validatePasswords(control, 'password2') ] ]
});

Note that we are passing additional context to the validatePasswords method (whether the source is password1 or password2).

  validatePasswords(control: AbstractControl, name: string) {
    if (this.registrationForm === undefined || this.password1.value === '' || this.password2.value === '') {
      return null;
    } else if (this.password1.value === this.password2.value) {
      if (name === 'password1' && this.password2.hasError('passwordMismatch')) {
        this.password1.setErrors(null);
        this.password2.updateValueAndValidity();
      } else if (name === 'password2' && this.password1.hasError('passwordMismatch')) {
        this.password2.setErrors(null);
        this.password1.updateValueAndValidity();
      }
      return null;
    } else {
      return {'passwordMismatch': { value: 'The provided passwords do not match'}};
    }  

Note here that when the passwords match, we coordinate with the other password field to have its validation updated. This will clear any stale password mismatch errors.

And for completeness sake, here are the getters that define this.password1 and this.password2.

  get password1(): AbstractControl {
    return this.registrationForm.get('password1');
  }

  get password2(): AbstractControl {
    return this.registrationForm.get('password2');
  }

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.

SQL 2016 solution/workaround here (could also work in earlier versions). This may not work or be appropriate in every situation, but I resolved the error by granting my database user read/write schema ownership as follows in SSMS:

Database > Security > Users > User > Properties > Owned Schemas > check db_datareader and db_datawriter.

This is from : Script to change password on linux servers over ssh

The script below will need to be saved as a file (eg ./passwdWrapper) and made executable (chmod u+x ./passwdWrapper)

#!/usr/bin/expect -f
#wrapper to make passwd(1) be non-interactive
#username is passed as 1st arg, passwd as 2nd

set username [lindex $argv 0]
set password [lindex $argv 1]
set serverid [lindex $argv 2]
set newpassword [lindex $argv 3]

spawn ssh $serverid passwd
expect "assword:"
send "$password\r"
expect "UNIX password:"
send "$password\r"
expect "password:"
send "$newpassword\r"
expect "password:"
send "$newpassword\r"
expect eof

Then you can run ./passwdWrapper $user $password $server $newpassword which will actually change the password.

Note: This requires that you install expect on the machine from which you will be running the command. (sudo apt-get install expect) The script works on CentOS 5/6 and Ubuntu 14.04, but if the prompts in passwd change, you may have to tweak the expect lines.

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 tried some of the suggested answers but it didn't resolve the issue. Finally I found out that the default connection timeout (not command timeout) is 15 seconds and once I increased it to 60 it almost never happened again. simply add this to you connection string: ;Connection Timeout=60 I chose 60 seconds but you can put any value you think would fit the best to your needs.

if your error is same like mine..just do this

right click on your table in sqlserver object explorer,choose properties in lower left corner in general option there is a connection block with server and connection specification.in your web config for datasource=. or local choose name specified in server in properties..

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.

Having just gone round the internet to read up on this and the options in Spring I'd second Luke's answer, use BCrypt (it's mentioned in the source code at Spring).

The best resource I found to explain why to hash/salt and why use BCrypt is a good choice is here: Salted Password Hashing - Doing it Right.

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 .

Its a common error which happens when we try to access a database which doesn't exist. So create the database using

CREATE DATABASE blog_development;

The error commonly occours when we have dropped the database using

DROP DATABASE blog_development;

and then try to access the database.

Regex for password:

/^(?=.*\d)(?=.*[A-Z])(?=.*[a-z])(?=.*[a-zA-Z!#$%&? "])[a-zA-Z0-9!#$%&?]{8,20}$/

Took me a while to figure out the restrictions, but I did it!

Restrictions: (Note: I have used >> and << to show the important characters)

1. Minimum 8 characters {>>8,20}
2. Maximum 20 characters {8,>>20}
3. At least one uppercase character (?=.*[A-Z])
4. At least one lowercase character (?=.*[a-z])
5. At least one digit (?=.*\d)
6. At least one special character (?=.*[a-zA-Z >>!#$%&? "<<])[a-zA-Z0-9 >>!#$%&?<< ]

IMHO it is considered as malformed header data.

You actually want to send those name value pairs as the request content (this is the way POST works) and not as headers.

The second way is true.

$(function() {
    $("#txtConfirmPassword").keyup(function() {
        var password = $("#txtNewPassword").val();
        $("#divCheckPasswordMatch").html(password == $(this).val()
            ? "Passwords match."
            : "Passwords do not match!"
        );
    });
});?

Demo here

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'

Open your mysql console and execute the following command (enter your database name,username and password):

GRANT ALL ON yourdatabasename.* TO admin@'%' IDENTIFIED BY 'yourRootPassword';

Then Execute:

FLUSH PRIVILEGES;

Open command line and open the file /etc/mysql/mysql.conf.d/mysqld.cnf using any editor with root privileges.

For example:

sudo nano /etc/mysql/mysql.conf.d/mysqld.cnf

Then comment out the below line:

bind-address = 127.0.0.1

Restart mysql to reflect the changes using command:

sudo service mysql restart

Enjoy ;)

I also see you're storing your passwords in plaintext (a big security no-no!). Consider using the built-in auth system instead.

This is an example to use ONLY p12 file it's not optimazed but it work. The pkcs12 file where generated by OpenSSL by me. Example how to load p12 file and build Trust zone from it... It outputs certificates from p12 file and add good certs to TrustStore

KeyStore ks=KeyStore.getInstance("pkcs12");
ks.load(new FileInputStream("client_t_c1.p12"),"c1".toCharArray());

KeyStore jks=KeyStore.getInstance("JKS");
jks.load(null);

for (Enumeration<String>t=ks.aliases();t.hasMoreElements();)
{
    String alias = t.nextElement();
    System.out.println("@:" + alias);
    if (ks.isKeyEntry(alias)){
        Certificate[] a = ks.getCertificateChain(alias);
        for (int i=0;i<a.length;i++)
        {
            X509Certificate x509 = (X509Certificate)a[i];
            System.out.println(x509.getSubjectDN().toString());
            if (i>0)
                jks.setCertificateEntry(x509.getSubjectDN().toString(), x509);
            System.out.println(ks.getCertificateAlias(x509));
            System.out.println("ok");
        }
    }
}

System.out.println("init Stores...");

KeyManagerFactory kmf=KeyManagerFactory.getInstance("SunX509");
kmf.init(ks, "c1".toCharArray());

TrustManagerFactory tmf=TrustManagerFactory.getInstance("SunX509");
tmf.init(jks);

SSLContext ctx = SSLContext.getInstance("TLS");
ctx.init(kmf.getKeyManagers(), tmf.getTrustManagers(), null);

In case anyone was curious, I was able to figure this out based on all of your responses combined!

This is in the Facelet:

<h:form id="myform">
  <h:inputSecret value="#{createNewPassword.newPassword1}" id="newPassword1" />
  <h:message class="error" for="newPassword1" id="newPassword1Error" />
  <h:inputSecret value="#{createNewPassword.newPassword2}" id="newPassword2" />
  <h:message class="error" for="newPassword2" id="newPassword2Error" />
  <h:commandButton value="Continue" action="#{createNewPassword.continueButton}" />
</h:form>

This is in the continueButton() method:

FacesContext.getCurrentInstance().addMessage("myForm:newPassword1", new FacesMessage(PASSWORDS_DONT_MATCH, PASSWORDS_DONT_MATCH));

And it works! Thanks for the help!

From your code, it looks like provider is a variant or some other variable, and not an object.

Is Nothing is for objects only, yet later you say it's a value that should either be NULL or NOT NULL, which would be handled by IsNull.

Try using:

If Not IsNull(provider) Then 
    url = url & "&provider=" & provider 
End if

Alternately, if that doesn't work, try:

If provider <> "" Then 
    url = url & "&provider=" & provider 
End if

Uncaught TypeError: undefined is not a function example_app.js:7

This error message tells the whole story. On this line, you are trying to execute a function. However, whatever is being executed is not a function! Instead, it's undefined.

So what's on example_app.js line 7? Looks like this:

var tasks = new ExampleApp.Collections.Tasks(data.tasks);

There is only one function being run on that line. We found the problem! ExampleApp.Collections.Tasks is undefined.

So lets look at where that is declared:

var Tasks = Backbone.Collection.extend({
    model: Task,
    url: '/tasks'
});

If that's all the code for this collection, then the root cause is right here. You assign the constructor to global variable, called Tasks. But you never add it to the ExampleApp.Collections object, a place you later expect it to be.

Change that to this, and I bet you'd be good.

ExampleApp.Collections.Tasks = Backbone.Collection.extend({
    model: Task,
    url: '/tasks'
});

See how important the proper names and line numbers are in figuring this out? Never ever regard errors as binary (it works or it doesn't). Instead read the error, in most cases the error message itself gives you the critical clues you need to trace through to find the real issue.

In Javascript, when you execute a function, it's evaluated like:

expression.that('returns').aFunctionObject(); // js
execute -> expression.that('returns').aFunctionObject // what the JS engine does

That expression can be complex. So when you see undefined is not a function it means that expression did not return a function object. So you have to figure out why what you are trying to execute isn't a function.

And in this case, it was because you didn't put something where you thought you did.

The principle of subqueries is not at all bad, but I don't think that you should use it in your example. If I understand correctly you want to get the maximum score for each date. In this case you should use a GROUP BY.

You cannot change the default but there is a codeless workaround.

Select the whole sheet and change the font size on your data to something small, like 10 or 12. When you zoom in to view the data you will find that the drop down box entries are now visible.

To emphasize, the issue is not so much with the size of the font in the drop down, it is the relative size between drop down and data display font sizes.

Well, STL is C++, not C, so I don't know what you want. If you want C, however, there is the rand() and srand() functions:

int rand(void);

void srand(unsigned seed);

These are both part of ANSI C. There is also the random() function:

long random(void);

But as far as I can tell, random() is not standard ANSI C. A third-party library may not be a bad idea, but it all depends on how random of a number you really need to generate.

You can dump the value in hex using UTL_RAW.CAST_TO_RAW(UTL_RAW.CAST_TO_VARCHAR2()).

SELECT b FROM foo;
-- (BLOB)

SELECT UTL_RAW.CAST_TO_RAW(UTL_RAW.CAST_TO_VARCHAR2(b))
FROM foo;
-- 1F8B080087CDC1520003F348CDC9C9D75128CF2FCA49D1E30200D7BBCDFC0E000000

This is handy because you this is the same format used for inserting into BLOB columns:

CREATE GLOBAL TEMPORARY TABLE foo (
    b BLOB);
INSERT INTO foo VALUES ('1f8b080087cdc1520003f348cdc9c9d75128cf2fca49d1e30200d7bbcdfc0e000000');

DESC foo;
-- Name Null Type 
-- ---- ---- ---- 
-- B        BLOB 

However, at a certain point (2000 bytes?) the corresponding hex string exceeds Oracle’s maximum string length. If you need to handle that case, you’ll have to combine How do I get textual contents from BLOB in Oracle SQL with the documentation for DMBS_LOB.SUBSTR for a more complicated approach that will allow you to see substrings of the BLOB.

This worked for me fine:

File 1:

    <html>
    <head></head>
    <body>
        <a href="#" onclick="window.open('file:///D:/Examples/file2.html'); return false">CLICK ME</a>
    </body>
    <footer></footer>
    </html>

File 2:

    <html>
        ...
    </html>

This method works regardless of whether or not the 2 files are in the same directory, BUT both files must be local.

For obvious security reasons, if File 1 is located on a remote server you absolutely cannot open a file on some client's host computer and trying to do so will open a blank target.

You can do it like this (with a slightly modified array to show it works for non-square arrays):

        long[,] arr = new long[5, 4] { { 1, 2, 3, 4 }, { 1, 1, 1, 1 }, { 2, 2, 2, 2 }, { 3, 3, 3, 3 }, { 4, 4, 4, 4 } };

        int rowLength = arr.GetLength(0);
        int colLength = arr.GetLength(1);

        for (int i = 0; i < rowLength; i++)
        {
            for (int j = 0; j < colLength; j++)
            {
                Console.Write(string.Format("{0} ", arr[i, j]));
            }
            Console.Write(Environment.NewLine + Environment.NewLine);
        }
        Console.ReadLine();

One should not recommend this as a general solution, but for one-off deletion of rows in a database that is not in production or in active use, you may be able to temporarily disable triggers on the tables in question.

In my case, I'm in development mode and have a couple of tables that reference one another via foreign keys. Thus, deleting their contents isn't quite as simple as removing all of the rows from one table before the other. So, for me, it worked fine to delete their contents as follows:

ALTER TABLE table1 DISABLE TRIGGER ALL;
ALTER TABLE table2 DISABLE TRIGGER ALL;
DELETE FROM table1;
DELETE FROM table2;
ALTER TABLE table1 ENABLE TRIGGER ALL;
ALTER TABLE table2 ENABLE TRIGGER ALL;

You should be able to add WHERE clauses as desired, of course with care to avoid undermining the integrity of the database.

There's some good, related discussion at http://www.openscope.net/2012/08/23/subverting-foreign-key-constraints-in-postgres-or-mysql/

Translation of source code into stuff-happening-on-the-[screen|disk|network] can occur in (roughly) two ways; call them compiling and interpreting.

In a compiled program (examples are c and fortran):

1. The source code is fed into another program (usually called a compiler--go figure), which produces an executable program (or an error).
2. The executable is run (by double clicking it, or typing it's name on the command line)

Things that happen in the first step are said to happen at "compile time", things that happen in the second step are said to happen at "run time".

In an interpreted program (example MicroSoft basic (on dos) and python (I think)):

1. The source code is fed into another program (usually called an interpreter) which "runs" it directly. Here the interpreter serves as an intermediate layer between your program and the operating system (or the hardware in really simple computers).

In this case the difference between compile time and run time is rather harder to pin down, and much less relevant to the programmer or user.

Java is a sort of hybrid, where the code is compiled to bytecode, which then runs on a virtual machine which is usually an interpreter for the bytecode.

There is also an intermediate case in which the program is compiled to bytecode and run immediately (as in awk or perl).

Your initial statement in the marked solution isn't entirely true. While your new solution may accomplish your original goal, it is still possible to circumvent the original error while preserving your AuthorizationHandler logic--provided you have basic authentication scheme handlers in place, even if they are functionally skeletons.

Speaking broadly, Authentication Handlers and schemes are meant to establish + validate identity, which makes them required for Authorization Handlers/policies to function--as they run on the supposition that an identity has already been established.

ASP.NET Dev Haok summarizes this best best here: "Authentication today isn't aware of authorization at all, it only cares about producing a ClaimsPrincipal per scheme. Authorization has to be aware of authentication somewhat, so AuthenticationSchemes in the policy is a mechanism for you to associate the policy with schemes used to build the effective claims principal for authorization (or it just uses the default httpContext.User for the request, which does rely on DefaultAuthenticateScheme)." https://github.com/aspnet/Security/issues/1469

In my case, the solution I'm working on provided its own implicit concept of identity, so we had no need for authentication schemes/handlers--just header tokens for authorization. So until our identity concepts changes, our header token authorization handlers that enforce the policies can be tied to 1-to-1 scheme skeletons.

[Authorize(AuthenticationSchemes = "AuthenticatedUserSchemeName", Policy = "AuthorizedUserPolicyName")]

Startup.cs:

        services.AddAuthentication(options =>
        {
            options.DefaultAuthenticateScheme = "AuthenticatedUserSchemeName";
        }).AddScheme<ValidTokenAuthenticationSchemeOptions, ValidTokenAuthenticationHandler>("AuthenticatedUserSchemeName", _ => { });

        services.AddAuthorization(options =>
        {
            options.AddPolicy("AuthorizedUserPolicyName", policy =>
            {
                //policy.RequireClaim(ClaimTypes.Sid,"authToken");
                policy.AddAuthenticationSchemes("AuthenticatedUserSchemeName");
                policy.AddRequirements(new ValidTokenAuthorizationRequirement());
            });
            services.AddSingleton<IAuthorizationHandler, ValidTokenAuthorizationHandler>();

Both the empty authentication handler and authorization handler are called (similar in setup to OP's respective posts) but the authorization handler still enforces our authorization policies.

I discovered the following, which prints out which lines, if any, have null characters:

perl -ne '/\000/ and print;' file-with-nulls

Also, an octal dump can tell you if there are nulls:

od file-with-nulls | grep ' 000'

For the newer emulator it might be helpful to launch from command line using:

emulator -netdelay none -netspeed full -avd <emulator_name> -http-proxy http://<ip-address>:8888

Make sure you follow @User9527's advice above as well for the rest of the setup

Capturing and grouping

Capturing group (pattern) creates a group that has capturing property.

A related one that you might often see (and use) is (?:pattern), which creates a group without capturing property, hence named non-capturing group.

A group is usually used when you need to repeat a sequence of patterns, e.g. (\.\w+)+, or to specify where alternation should take effect, e.g. ^(0*1|1*0)$ (^, then 0*1 or 1*0, then $) versus ^0*1|1*0$ (^0*1 or 1*0$).

A capturing group, apart from grouping, will also record the text matched by the pattern inside the capturing group (pattern). Using your example, (.*):, .* matches ABC and : matches :, and since .* is inside capturing group (.*), the text ABC is recorded for the capturing group 1.

Group number

The whole pattern is defined to be group number 0.

Any capturing group in the pattern start indexing from 1. The indices are defined by the order of the opening parentheses of the capturing groups. As an example, here are all 5 capturing groups in the below pattern:

(group)(?:non-capturing-group)(g(?:ro|u)p( (nested)inside)(another)group)(?=assertion)
|     |                       |          | |      |      ||       |     |
1-----1                       |          | 4------4      |5-------5     |
                              |          3---------------3              |
                              2-----------------------------------------2

The group numbers are used in back-reference \n in pattern and $n in replacement string.

^{In other regex flavors (PCRE, Perl), they can also be used in sub-routine calls.}

You can access the text matched by certain group with Matcher.group(int group). The group numbers can be identified with the rule stated above.

^{In some regex flavors (PCRE, Perl), there is a branch reset feature which allows you to use the same number for capturing groups in different branches of alternation.}

Group name

From Java 7, you can define a named capturing group (?<name>pattern), and you can access the content matched with Matcher.group(String name). The regex is longer, but the code is more meaningful, since it indicates what you are trying to match or extract with the regex.

The group names are used in back-reference \k<name> in pattern and ${name} in replacement string.

Named capturing groups are still numbered with the same numbering scheme, so they can also be accessed via Matcher.group(int group).

Internally, Java's implementation just maps from the name to the group number. Therefore, you cannot use the same name for 2 different capturing groups.

You can change the color of the text in the toolbar with these:

<item name="android:textColorPrimary">#FFFFFF</item>
<item name="android:textColor">#FFFFFF</item>

declare @LkeVal as Varchar(100)
declare @LkeSelect Varchar(100)

Set @LkeSelect = (select top 1 <column> from <table> where <column> = 'value')
Set @LkeVal = '%' + @LkeSelect

select * from <table2> where <column2> like(''+@LkeVal+'');

Try this: Python Property

The sample code is:

class C(object):
    def __init__(self):
        self._x = None

    @property
    def x(self):
        """I'm the 'x' property."""
        print("getter of x called")
        return self._x

    @x.setter
    def x(self, value):
        print("setter of x called")
        self._x = value

    @x.deleter
    def x(self):
        print("deleter of x called")
        del self._x


c = C()
c.x = 'foo'  # setter called
foo = c.x    # getter called
del c.x      # deleter called

With Underscore

Underscore provides a function _.mapObject to map the values and preserve the keys.

_.mapObject({ one: 1, two: 2, three: 3 }, function (v) { return v * 3; });

// => { one: 3, two: 6, three: 9 }

DEMO

With Lodash

Lodash provides a function _.mapValues to map the values and preserve the keys.

_.mapValues({ one: 1, two: 2, three: 3 }, function (v) { return v * 3; });

// => { one: 3, two: 6, three: 9 }

I'd probably use an ImageIcon and set it on a JLabel which I'd add to the JPanel.

Here's Sun's docs on the subject matter.

So starting with the answer given and applying the fact that CSS3 allows multiple settings - the below code is useful for creating a complete box:

#border {_x000D_
  width: 200px;_x000D_
  height: 100px;_x000D_
  background: yellow;_x000D_
  text-align: center;_x000D_
  line-height: 100px;_x000D_
  background: linear-gradient(to right, orange 50%, rgba(255, 255, 255, 0) 0%), linear-gradient(blue 50%, rgba(255, 255, 255, 0) 0%), linear-gradient(to right, green 50%, rgba(255, 255, 255, 0) 0%), linear-gradient(red 50%, rgba(255, 255, 255, 0) 0%);_x000D_
  background-position: top, right, bottom, left;_x000D_
  background-repeat: repeat-x, repeat-y;_x000D_
  background-size: 10px 1px, 1px 10px;_x000D_
}

<div id="border">_x000D_
  bordered area_x000D_
</div>

Its worth noting that the 10px in the background size gives the area that the dash and gap will cover. The 50% of the background tag is how wide the dash actually is. It is therefore possible to have different length dashes on each border side.

I had same mistake, it was produced because i had disabled the creation of "_jvm" in the InstallAnywhere (project - JVM settings - Installer Settings - Bundled/Downloaded Virtual Machine), then into file "Uninstall $PRODUCT_NAME$.lax" into uninstall folder, the variable "lax.nl.current.vm" is empty.

If you don't need jvm is disabled check "Install Bundled / Downloaded Virtual Machine" option in the checkbox (project - JVM settings - Installer Settings - Bundled/Downloaded Virtual Machine).

If you need jvm is disabled because you create it manually, then you can do the following: create an action "Modify Text File" to append variable with the value of the _jvm folder.

(Existing File)
$USER_INSTALL_DIR$\Uninstall_$PRODUCT_NAME$ \Uninstall $PRODUCT_NAME$.lax

(Append)

lax.nl.current.vm=..\_jvm\bin\java.exe

Remove padding between cells inside the table. Just use cellpadding=0 and cellspacing=0 attributes in table tag.

Page is a special case handler.

Generic Web handler (*.ashx, extension based processor) is the default HTTP handler for all Web handlers that do not have a UI and that include the @WebHandler directive.

ASP.NET page handler (*.aspx) is the default HTTP handler for all ASP.NET pages.

Among the built-in HTTP handlers there are also Web service handler (*.asmx) and Trace handler (trace.axd)

MSDN says:

An ASP.NET HTTP handler is the process (frequently referred to as the "endpoint") that runs in response to a request made to an ASP.NET Web application. The most common handler is an ASP.NET page handler that processes .aspx files. When users request an .aspx file, the request is processed by the page through the page handler.

The image below illustrates this:

As to your second question:

Does ashx handle more connections than aspx?

Don't think so (but for sure, at least not less than).

You can use a background image

.application-title img {_x000D_
  width:200px;_x000D_
  height:200px;_x000D_
  box-sizing:border-box;_x000D_
  padding-left: 200px;_x000D_
  /*width of the image*/_x000D_
  background: url(http://lorempixel.com/200/200/city/2) left top no-repeat;_x000D_
}

<div class="application-title">_x000D_
  <img src="http://lorempixel.com/200/200/city/1/">_x000D_
</div><br />_x000D_
Original Image: <br />_x000D_
_x000D_
<img src="http://lorempixel.com/200/200/city/1/">

When using most functions of objects with apply or call, the context parameter MUST be the object you are working on.

In this case, you need a.push.apply(a, [1,2]) (or more correctly Array.prototype.push.apply(a, [1,2]))

This is easy to do, you can render the report as a PDF, and save the resulting byte array as a PDF file on disk. To do this in the background, that's more a question of how your app is written. You can just spin up a new thread, or use a BackgroundWorker (if this is a WinForms app), etc. There, of course, may be multithreading issues to be aware of.

Warning[] warnings;
string[] streamids;
string mimeType;
string encoding;
string filenameExtension;

byte[] bytes = reportViewer.LocalReport.Render(
    "PDF", null, out mimeType, out encoding, out filenameExtension,
    out streamids, out warnings);

using (FileStream fs = new FileStream("output.pdf", FileMode.Create))
{
    fs.Write(bytes, 0, bytes.Length);
}

Regarding the second part of your question, serialization is a persistence mechanism used to store objects as a sequence of signed bytes. Put less formally, it stores the state of an object so you can retrieve it later, by deserialization.

Yes, gcc can also compile assembly source code. Alternatively, you can invoke as, which is the assembler. (gcc is just a "driver" program that uses heuristics to call C compiler, C++ compiler, assembler, linker, etc..)

If you know the height of the div you want to center, you can position it absolutely within its parent and then set the top value to 50%. That will put the top of the child div 50% of the way down its parent, i.e. too low. Pull it back up by setting its margin-top to half its height. So now you have the vertical midpoint of the child div sitting at the vertical midpoint of the parent - vertically centered!

Example:

.black {_x000D_
    position:absolute;_x000D_
    top:0;_x000D_
    bottom:0;_x000D_
    left:0;_x000D_
    right:0;_x000D_
    background:rgba(0,0,0,.5);_x000D_
}_x000D_
.message {_x000D_
    background:yellow;_x000D_
    width:200px;_x000D_
    margin:auto auto;_x000D_
    padding:10px;_x000D_
    position: absolute;_x000D_
    top: 50%;_x000D_
    margin-top: -25px;_x000D_
    height: 50px;_x000D_
}

<div class="black">_x000D_
    <div class="message">_x000D_
        This is a popup message._x000D_
    </div>_x000D_

This will print everything after each match, on that same line only:

perl -lne 'print $1 if /^potato:\s*(.*)/' file.txt

This will do the same, except it will also print all subsequent lines:

perl -lne 'if ($found){print} elsif (/^potato:\s*(.*)/){print $1; $found++}' file.txt

These command-line options are used:

• -n loop around each line of the input file
• -l removes newlines before processing, and adds them back in afterwards
• -e execute the perl code

I just found this excellent little tutorial. broken link (Cached version)

I also followed Microsoft's tutorial which is nice, but I only needed pipes as well.

As you can see, you don't need configuration files and all that messy stuff.

By the way, he uses both HTTP and pipes. Just remove all code lines related to HTTP, and you'll get a pure pipe example.

How about dropping the entire database and then creating it again? This works for me.

One of the many unnecessary complex things about Java making it unintuitive to use. Why instance variables are initialized with default 0 but local are not is not logical. Similar why enums dont have built in flag support and many more options. Java lambda is a nightmare compared to C# and not allowing class extension methods is also a big problem.

Java ecosystem comes up with excuses why its not possible but me as the user / developer i dont care about their excuses. I want easy approach and if they dont fix those things they will loose big in the future since C# and other languages are not waiting to make life of developers more simple. Its just sad to see the decline in the last 10 years since i work daily with Java.

if solution does not work , than its worth your time meddling with services.msc

The easiest way is to just learn how to do DOM traversing and manipulation with the plain DOM api (you would probably call this: normal JavaScript).

This can however be a pain for some things. (which is why libraries were invented in the first place).

Googling for "javascript DOM traversing/manipulation" should present you with plenty of helpful (and some less helpful) resources.

The articles on this website are pretty good: http://www.htmlgoodies.com/primers/jsp/

And as Nosredna points out in the comments: be sure to test in all browsers, because now jQuery won't be handling the inconsistencies for you.

_{Additional details to the previous answer:}

While React's setState is asynchronous (both classes and hooks), and it's tempting to use that fact to explain the observed behavior, it is not the reason why it happens.

TLDR: The reason is a closure scope around an immutable const value.

Solutions:

• read the value in render function (not inside nested functions):

    useEffect(() => { setMovies(result) }, [])
    console.log(movies)
  

• add the variable into dependencies (and use the react-hooks/exhaustive-deps eslint rule):

    useEffect(() => { setMovies(result) }, [])
    useEffect(() => { console.log(movies) }, [movies])
  

• use a mutable reference (when the above is not possible):

    const moviesRef = useRef(initialValue)
    useEffect(() => {
      moviesRef.current = result
      console.log(moviesRef.current)
    }, [])
  

Explanation why it happens:

If async was the only reason, it would be possible to await setState().

However, both props and state are assumed to be unchanging during 1 render.

Treat this.state as if it were immutable.

With hooks, this assumption is enhanced by using constant values with the const keyword:

const [state, setState] = useState('initial')

The value might be different between 2 renders, but remains a constant inside the render itself and inside any closures (functions that live longer even after render is finished, e.g. useEffect, event handlers, inside any Promise or setTimeout).

Consider following fake, but synchronous, React-like implementation:

// sync implementation:

let internalState
let renderAgain

const setState = (updateFn) => {
  internalState = updateFn(internalState)
  renderAgain()
}

const useState = (defaultState) => {
  if (!internalState) {
    internalState = defaultState
  }
  return [internalState, setState]
}

const render = (component, node) => {
  const {html, handleClick} = component()
  node.innerHTML = html
  renderAgain = () => render(component, node)
  return handleClick
}

// test:

const MyComponent = () => {
  const [x, setX] = useState(1)
  console.log('in render:', x) // ?
  
  const handleClick = () => {
    setX(current => current + 1)
    console.log('in handler/effect/Promise/setTimeout:', x) // ? NOT updated
  }
  
  return {
    html: `<button>${x}</button>`,
    handleClick
  }
}

const triggerClick = render(MyComponent, document.getElementById('root'))
triggerClick()
triggerClick()
triggerClick()

<div id="root"></div>

from operator import itemgetter
data.sort(key=itemgetter(1))

You can use inner divs to set the margin.

<div style="display: table-cell;">
   <div style="margin:5px;background-color: red;">1</div>
</div>
<div style="display: table-cell; ">
  <div style="margin:5px;background-color: green;">1</div>
</div>

Another possibile solution is,maybe your file is ASCII type file,just change the type of your files.

When you use scp you have to tell the host name and ip address from where you want to copy the file. For instance, if you are at the remote host and you want to transfer the file to your pc you may use something like this:

scp -P[portnumber] myfile_at_remote_host [user]@[your_ip_address]:/your/path/

Example:

scp -P22 table [email protected]:/home/me/Desktop/

On the other hand, if you are at your are actually on your machine you may use something like this:

scp -P[portnumber] [remote_login]@[remote's_ip_address]:/remote/path/myfile_at_remote_host /your/path/

To install PDT (PHP Development Tools) for PHP development environment is better in Eclipse. The following are the steps to install PDT in Eclipse (I'm considering version 3.7 (Indigo)):

1. Open Eclipse (in my case Eclipse Indigo).
2. Go to Help --> Install New Software...
3. Expand the "Work with" drop down and select "Indigo - http://download.eclipse.org/releases/indigo".
4. Expand "Programming Languages" from the list.
5. Check PHP Development Tools (PDT) SDK Feature.
6. Click "Next >" at the bottom and follow the further instruction of Eclipse.
7. After successful installation of PDT: Go to Window --> Preferences and see the list as PHP at left panel.

This post contains 2 examples. I like the 2nd one:

Sub unique() 
  Dim arr As New Collection, a 
  Dim aFirstArray() As Variant 
  Dim i As Long 
 
  aFirstArray() = Array("Banana", "Apple", "Orange", "Tomato", "Apple", _ 
  "Lemon", "Lime", "Lime", "Apple") 
 
  On Error Resume Next 
  For Each a In aFirstArray 
     arr.Add a, a 
  Next
  On Error Goto 0 ' added to original example by PEH
 
  For i = 1 To arr.Count 
     Cells(i, 1) = arr(i) 
  Next 
 
End Sub 

use Values either while creating variable X or while encoding as mentioned above

# Importing the libraries
import numpy as np
import matplotlib.pyplot as plt
import pandas as pd

# Importing the dataset
# dataset = pd.read_csv('50_Startups.csv')

dataset = pd.DataFrame(np.random.rand(10, 10))
y=dataset.iloc[:, 4].values
X=dataset.iloc[:, 0:4].values

None of the Answers worked for me. Here is a simple way.

searchEditText.setVisibility(View.VISIBLE);
                final Handler handler=new Handler();
                handler.postDelayed(new Runnable() {
                    @Override
                    public void run() {
                        searchEditText.requestFocus();
                    }
                }, 400);

Just delayed the requestFocus() method for 400ms.

You need to apply DATE_FORMAT in the SELECT clause, not the WHERE clause:

SELECT  DATE_FORMAT(create_date, '%m/%d/%Y')
FROM    mytable
WHERE   create_date BETWEEN CURDATE() - INTERVAL 30 DAY AND CURDATE()

Also note that CURDATE() returns only the DATE portion of the date, so if you store create_date as a DATETIME with the time portion filled, this query will not select the today's records.

In this case, you'll need to use NOW instead:

SELECT  DATE_FORMAT(create_date, '%m/%d/%Y')
FROM    mytable
WHERE   create_date BETWEEN NOW() - INTERVAL 30 DAY AND NOW()

You just need to write the first query as a subquery (derived table), inside parentheses, pick an alias for it (t below) and alias the columns as well.

The DISTINCT can also be safely removed as the internal GROUP BY makes it redundant:

SELECT DATE(`date`) AS `date` , COUNT(`player_name`) AS `player_count`
FROM (
    SELECT MIN(`date`) AS `date`, `player_name`
    FROM `player_playtime`
    GROUP BY `player_name`
) AS t
GROUP BY DATE( `date`) DESC LIMIT 60 ;

Since the COUNT is now obvious that is only counting rows of the derived table, you can replace it with COUNT(*) and further simplify the query:

SELECT t.date , COUNT(*) AS player_count
FROM (
    SELECT DATE(MIN(`date`)) AS date
    FROM player_playtime
    GROUP BY player_name
) AS t
GROUP BY t.date DESC LIMIT 60 ;

Ctrl+C is what you need. If it didn't work, hit it harder. :-) Of course, you can also just close the shell window.

Edit: You didn't mention the circumstances. As a last resort, you could write a batch file that contains taskkill /im python.exe, and put it on your desktop, Start menu, etc. and run it when you need to kill a runaway script. Of course, it will kill all Python processes, so be careful.

You're looking to create a custom A record.

I'm pretty sure that you can use wildcards when specifying A records which would let you do something like this:

*.mywebsite.com       IN  A       127.0.0.1

127.0.0.1 would be the IP address of your webserver. The method of actually adding the record will depend on your host.

Doing it like http://mywebsite.com/user would be a lot easier to set up if it's an option.

Then you could just add a .htaccess file that looks like this:

Options +FollowSymLinks

RewriteEngine On
RewriteRule ^([aA-zZ])$  dostuff.php?username=$1

In the above, usernames are limited to the characters a-z

The rewrite rule for grabbing the subdomain would look like this:

RewriteCond %{HTTP_HOST} ^(^.*)\.mywebsite.com
RewriteRule (.*)  dostuff.php?username=%1

However, you don't really need any rewrite rules. The HTTP_HOST header is available in PHP as well, so you can get it already, like

$username = strtok($_SERVER['HTTP_HOST'], ".");

I faced the same problem on Windows 10. As soon as I cleared my Path variable from edit environment variables option, the icon started to appear. It was occurring because I had previously installed python 3.6.1 on my computer and added it to my path variable as C:\Python36;C:\Python36\DLL; and so on. There isn't any need to uninstall Anaconda Navigator and start from scratch if you have correctly followed the steps mentioned at the documentation for it.

As per https://android.stackexchange.com/a/78183/239063 you can run a one line command in Linux to add in an appropriate tar header to extract it.

( printf "\x1f\x8b\x08\x00\x00\x00\x00\x00" ; tail -c +25 backup.ab ) | tar xfvz -

Replace backup.ab with the path to your file.

For python >= 3.5 you can use **, recursive=True :

import glob
for x in glob.glob('/path/**/*.c', recursive=True):
    print(x)

Demo

If recursive is True, the pattern ** will match any files and zero or more directories and subdirectories. If the pattern is followed by an os.sep, only directories and subdirectories match.

Note:

Python3.6 seems to default to recursive=True when using ** so it can be omitted.

Pure css way of trim multiline text with ellipsis

Adjust text container's hight, control line to break by -webkit-line-clamp: 2;

.block-ellipsis {
  display: block;
  display: -webkit-box;
  max-width: 100%;
  height: 30px;
  margin: 0 auto;
  font-size: 14px;
  line-height: 1;
  -webkit-line-clamp: 2;
  -webkit-box-orient: vertical;
  overflow: hidden;
  text-overflow: ellipsis;
}

If you have a grep with a -P option for a limited perl regex, you can use

grep -P '(?=.*string1)(?=.*string2)'

which has the advantage of working with overlapping strings. It's somewhat more straightforward using perl as grep, because you can specify the and logic more directly:

perl -ne 'print if /string1/ && /string2/'

I just want to add that if you want to somehow store the encrypted byte array as String and then retrieve it and decrypt it (often for obfuscation of database values) you can use this approach:

import java.security.Key;
import javax.crypto.Cipher;
import javax.crypto.spec.SecretKeySpec;
public class StrongAES 
{
    public void run() 
    {
        try 
        {
            String text = "Hello World";
            String key = "Bar12345Bar12345"; // 128 bit key
            // Create key and cipher
            Key aesKey = new SecretKeySpec(key.getBytes(), "AES");
            Cipher cipher = Cipher.getInstance("AES");
            // encrypt the text
            cipher.init(Cipher.ENCRYPT_MODE, aesKey);
            byte[] encrypted = cipher.doFinal(text.getBytes());

            StringBuilder sb = new StringBuilder();
            for (byte b: encrypted) {
                sb.append((char)b);
            }

            // the encrypted String
            String enc = sb.toString();
            System.out.println("encrypted:" + enc);

            // now convert the string to byte array
            // for decryption
            byte[] bb = new byte[enc.length()];
            for (int i=0; i<enc.length(); i++) {
                bb[i] = (byte) enc.charAt(i);
            }

            // decrypt the text
            cipher.init(Cipher.DECRYPT_MODE, aesKey);
            String decrypted = new String(cipher.doFinal(bb));
            System.err.println("decrypted:" + decrypted);

        }
        catch(Exception e) 
        {
            e.printStackTrace();
        }
    }
    public static void main(String[] args) 
    {
        StrongAES app = new StrongAES();
        app.run();
    }
}

There is a simple why that I prefered to the bundle due to the no duplicate data in memory. It consists of a init public method for the fragment

private ArrayList<Music> listMusics = new ArrayList<Music>();
private ListView listMusic;


public static ListMusicFragment createInstance(List<Music> music) {
    ListMusicFragment fragment = new ListMusicFragment();
    fragment.init(music);
    return fragment;
}

public void init(List<Music> music){
    this.listMusic = music;
}

@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container, 
    Bundle savedInstanceState)
{

    View view = inflater.inflate(R.layout.musiclistview, container, false);
    listMusic = (ListView) view.findViewById(R.id.musicListView);
    listMusic.setAdapter(new MusicBaseAdapter(getActivity(), listMusics));

    return view;
}
}

In two words, you create an instance of the fragment an by the init method (u can call it as u want) you pass the reference of your list without create a copy by serialization to the instance of the fragment. This is very usefull because if you change something in the list u will get it in the other parts of the app and ofcourse, you use less memory.

I restarted my computer and then opened the IDE again and it worked while none of the above did.

Maybe you have to do the things above as well, but make sure to restart the computer too.

I ran into the same problem.

In most scenarios using the hack-ish setTimeout(() => { }, 0) in componentDidMount() worked.

But not in a special case; and I didn't want to use the ReachDOM findDOMNode since the documentation says:

Note: findDOMNode is an escape hatch used to access the underlying DOM node. In most cases, use of this escape hatch is discouraged because it pierces the component abstraction.

(Source: findDOMNode)

So in that particular component I had to use the componentDidUpdate() event, so my code ended up being like this:

componentDidMount() {
    // feel this a little hacky? check this: http://stackoverflow.com/questions/26556436/react-after-render-code
    setTimeout(() => {
       window.addEventListener("resize", this.updateDimensions.bind(this));
       this.updateDimensions();
    }, 0);
}

And then:

componentDidUpdate() {
    this.updateDimensions();
}

Finally, in my case, I had to remove the listener created in componentDidMount:

componentWillUnmount() {
    window.removeEventListener("resize", this.updateDimensions.bind(this));
}

Also check SELINUX (/etc/selinux):

# getenforce

turn it off:

# setenforce 0

Use Hibernate.initialize() within @Transactional to initialize lazy objects.

 start Transaction 
      Hibernate.initialize(entity.getAddresses());
      Hibernate.initialize(entity.getPersons());
 end Transaction 

Now out side of the Transaction you are able to get lazy objects.

entity.getAddresses().size();
entity.getPersons().size();

Use worksheet.find (worksheet is your worksheet) and use the row-range for its range-object. You can get the rangeobject like: worksheet.rows(rowIndex) as example

Then give find the required parameters it should find it for you fine. If I recall correctly, find returns the first match per default. I have no Excel at hand, so you have to look up find for yourself, sorry

I would advise against using a for-loop it is more fragile and ages slower than find.

The error is very straight forward, you imported react instead of React.

TechView.jsx

import React , { Component} from 'react';

class TechView extends Component {

    constructor(props){
       super(props);
       this.state = {
           name:'Gopinath'
       }
    }

    render(){
        return(
            <span>hello Tech View</span>
        );
    }
}

export default TechView;

Also you don't need to import render in the above code unless it's the root level index.js.

index.js:

import React from 'react';
import ReactDOM from 'react-dom';
import './index.css';
import TechView from './TechView';
import * as serviceWorker from './serviceWorker';

ReactDOM.render(
  <React.StrictMode>
    <TechView />
  </React.StrictMode>,
  document.getElementById('root')
);

serviceWorker.unregister();

Note: You could have imported render the way you did in your original post and used it directly:

import React from 'react';
import { render } from 'react-dom';
import './index.css';
import TechView from './TechView';
import * as serviceWorker from './serviceWorker';

render(
  <React.StrictMode>
    <TechView />
  </React.StrictMode>,
  document.getElementById('root')
);

serviceWorker.unregister();

Here, TechView becomes the main react component, which is conventionally also known as App. So, in this context instead of naming the file as TechView.jsx I'd name it App.jsx and instead of naming the class as TechView I'd name it App.

If d is a dictionary, then d.get(k, v) means, give me the value of k in d, unless k isn't there, in which case give me v. It's being used here to get the current count of the character, which should start at 0 if the character hasn't been encountered before.

[ngClass]=... instead of *ngClass.

* is only for the shorthand syntax for structural directives where you can for example use

<div *ngFor="let item of items">{{item}}</div>

instead of the longer equivalent version

<template ngFor let-item [ngForOf]="items">
  <div>{{item}}</div>
</template>

Well, you can stick one or more "soft hyphens" (­) in your long unbroken strings. I doubt that old IE versions deal with that correctly, but what it's supposed to do is tell the browser about allowable word breaks that it can use if it has to.

Now, how exactly would you pick where to stuff those characters? That depends on the actual string and what it means, I guess.

min and max have to loop through the input array anyway - how else would they find the biggest or smallest element?

So just a quick for..in loop will work just fine.

var min = Infinity, max = -Infinity, x;
for( x in input) {
    if( input[x] < min) min = input[x];
    if( input[x] > max) max = input[x];
}

Try this one -

"SELECT 
       ID, Salt, password, BannedEndDate
     , (
          SELECT COUNT(1)
          FROM dbo.LoginFails l
          WHERE l.UserName = u.UserName
               AND IP = '" + Request.ServerVariables["REMOTE_ADDR"] + "'
      ) AS cnt
FROM dbo.Users u
WHERE u.UserName = '" + LoginModel.Username + "'"

If you want to use the same date format among multiple threads, declare it as a static and synchronize on the instance variable when using it...

static private SimpleDateFormat sdf = new SimpleDateFormat("....");

synchronized(sdf)
{
   // use the instance here to format a date
}


// The above makes it thread safe

I had a similar issue: to count all distinct values, counting null values as 1, too. A simple count doesn't work in this case, as it does not take null values into account.

Here's a snippet that works on SQL and does not involve selection of new values. Basically, once performed the distinct, also return the row number in a new column (n) using the row_number() function, then perform a count on that column:

SELECT COUNT(n)
FROM (
    SELECT *, row_number() OVER (ORDER BY [MyColumn] ASC) n
    FROM (
        SELECT DISTINCT [MyColumn]
                    FROM [MyTable]
        ) items  
) distinctItems

Here's what we all want:

function Enum(constantsList) {
    for (var i in constantsList) {
        this[constantsList[i]] = i;
    }
}

Now you can create your enums:

var YesNo = new Enum(['NO', 'YES']);
var Color = new Enum(['RED', 'GREEN', 'BLUE']);

By doing this, constants can be acessed in the usual way (YesNo.YES, Color.GREEN) and they get a sequential int value (NO = 0, YES = 1; RED = 0, GREEN = 1, BLUE = 2).

You can also add methods, by using Enum.prototype:

Enum.prototype.values = function() {
    return this.allValues;
    /* for the above to work, you'd need to do
            this.allValues = constantsList at the constructor */
};

Edit - small improvement - now with varargs: (unfortunately it doesn't work properly on IE :S... should stick with previous version then)

function Enum() {
    for (var i in arguments) {
        this[arguments[i]] = i;
    }
}

var YesNo = new Enum('NO', 'YES');
var Color = new Enum('RED', 'GREEN', 'BLUE');

Check for a network connection using GetIsNetworkAvailable() to avoid creating empty files when not connected to a network.

if (System.Net.NetworkInformation.NetworkInterface.GetIsNetworkAvailable())
{
    using (System.Net.WebClient client = new System.Net.WebClient())
    {                        
          client.DownloadFileAsync(new Uri("http://www.examplesite.com/test.txt"),
          "D:\\test.txt");
    }                  
}

You can create a PrintStream wrapping around your OutputStream and then just call it's print(String):

final OutputStream os = new FileOutputStream("/tmp/out");
final PrintStream printStream = new PrintStream(os);
printStream.print("String");
printStream.close();

Just to add a little further documentation to this page - I have been struggling with this problem for a while.

As said above, the easiest way to get the URL is via window.location.href.

we can then extract parts of the URL through vanilla Javascript by using let urlElements = window.location.href.split('/')

We would then console.log(urlElements) to see the Array of elements produced by calling .split() on the URL.

Once you have found which index in the array you want to access, you can then assigned this to a variable

let urlElelement = (urlElements[0])

And now you can use the value of urlElement, which will be the specific part of your URL, wherever you want.

Why not use:

Dim msg as String = String.Format("Variable = {0}", variable)

When compiling with G++, remember to put the -lpthread flag :)

There are two ways you can count the number of rows.

$query = "SELECT count(*) as total from table1";
$prepare = $link->prepare($query);
$prepare->execute();
$row = $prepare->fetch(PDO::FETCH_ASSOC);
echo $row['total']; // This will return you a number of rows.

Or second way is

$query = "SELECT field1, field2 from table1";
$prepare = $link->prepare($query);
$prepare->execute();
$row = $prepare->fetch(PDO::FETCH_NUM);
echo $rows[0]; // This will return you a number of rows as well.

Decimal. If you choose double you're leaving yourself open to rounding errors

If you need binary mode, you'll need to do it the hard way:

s = File.open(filename, 'rb') { |f| f.read }

If not, shorter and sweeter is:

s = IO.read(filename)

An important part of using a key down on tab is knowing that tab will always try to do something already, don't forget to "return false" at the end.

Here is what I did. I have a function that runs on .blur and a function that swaps where my form focus is. Basically it adds an input to the end of the form and goes there while running calculations on blur.

$(this).children('input[type=text]').blur(timeEntered).keydown(function (e) {
        var code = e.keyCode || e.which;
        if (code == "9") {
            window.tabPressed = true;
            // Here is the external function you want to call, let your external
            // function handle all your custom code, then return false to
            // prevent the tab button from doing whatever it would naturally do.
            focusShift($(this));
            return false;
        } else {
            window.tabPressed = false;
        }
        // This is the code i want to execute, it might be different than yours
        function focusShift(trigger) {
            var focalPoint = false;
            if (tabPressed == true) {
                console.log($(trigger).parents("td").next("td"));
                focalPoint = $(trigger).parents("td").next("td");

            }
            if (focalPoint) {
                $(focalPoint).trigger("click");
            }
        }
    });

You can. But by placing this in the constructor you are making your object hard to test.

Instead you should:

• provide the configuration with a setter
• have a separate init() method

Dependency injection frameworks give you these options.

public class ConfigurableObject {
   private Map<String, String> configuration;
   public ConfigurableObject() {

   }

   public void setConfiguration(..) {
       //...simply set the configuration
   }
}

An example of the 2nd option (best used when the object is managed by a container):

public class ConfigurableObject {
   private File configFile;
   private Map<String, String> configuration;
   public ConfigurableObject(File configFile) {
       this.configFile = configFile;
   }

   public void init() {
       this.configuration = parseConfig(); // implement
   }
}

This, of course, can be written by just having the constructor

public ConfigurableObject(File configfile) {
    this.configuration = parseConfig(configFile);
}

But then you won't be able to provide mock configurations.

I know the 2nd opttion sounds more verbose and prone to error (if you forget to initialize). And it won't really hurt you that much if you do it in a constructor. But making your code more dependency-injection oriented is generally a good practice.

The 1st option is best - it can be used with both DI framework and with manual DI.

A trick to make a PDF with complex features is to make a dummy activity with the desired xml layout. You can then open this dummy activity, take a screenshot programmatically and convert that image to pdf using this library. Of course there are limitations such as not being able to scroll, not more than one page,but for a limited application this is quick and easy. Hope this helps someone!

The two structs are different. When you initialize the first struct, about 40 bytes of memory are allocated. When you initialize the second struct, about 10 bytesof memory are allocated. (Actual amount is architecture dependent)

You can use the string literals (string constants) to initalize character arrays. This is why

person p = {"John", "Doe",30};

works in the first example.

You cannot assign (in the conventional sense) a string in C.

The string literals you have ("John") are loaded into memory when your code executes. When you initialize an array with one of these literals, then the string is copied into a new memory location. In your second example, you are merely copying the pointer to (location of) the string literal. Doing something like:

char* string = "Hello";
*string = 'C'

might cause compile or runtime errors (I am not sure.) It is a bad idea because you are modifying the literal string "Hello" which, for example on a microcontroler, could be located in read-only memory.

If you are using maven in the jersey project add below in pom.xml and update project dependencies so that Jaxb is able to detect model class and convert list to Media type application XML:

<dependency>
    <groupId>com.sun.xml.bind</groupId>
    <artifactId>jaxb-core</artifactId>
    <version>2.2.11</version>
</dependency>

This may help you.

1. Right click on git bash -> properties
2. In Shorcut tab -> Start in field -> enter your user defined path
3. Make sure the Target field does not include --go-to-home or it will continue to start in the directory specified in your HOME variable

Thats it.

Change the SDK directory to C:\Users\username\AppData\Local\Android\Sdk

If you are using the latest android studio you can configure this using Configure -> Project Defaults -> Project Structure

If it helps anyone, here is what I got working in Python using the Python Requests library instead of CURL.

As explained by @staypuftman above, you will need your API Key and List ID from MailChimp and make sure your API Key suffix and URL prefix (i.e. us5) match.

Python:

#########################################################################################
# To add a single contact to MailChimp (using MailChimp v3.0 API), requires:
#   + MailChimp API Key
#   + MailChimp List Id for specific list
#   + MailChimp API URL for adding a single new contact
#
# Note: the API URL has a 3/4 character location subdomain at the front of the URL string. 
# It can vary depending on where you are in the world. To determine yours, check the last 
# 3/4 characters of your API key. The API URL location subdomain must match API Key 
# suffix e.g. us5, us13, us19 etc. but in this example, us5.
# (suggest you put the following 3 values in 'settings' or 'secrets' file)
#########################################################################################
MAILCHIMP_API_KEY = 'your-api-key-here-us5'
MAILCHIMP_LIST_ID = 'your-list-id-here'
MAILCHIMP_ADD_CONTACT_TO_LIST_URL = 'https://us5.api.mailchimp.com/3.0/lists/' + MAILCHIMP_LIST_ID + '/members/'

    # Create new contact data and convert into JSON as this is what MailChimp expects in the API
    # I've hardcoded some test data but use what you get from your form as appropriate
    new_contact_data_dict = {
        "email_address": "[email protected]",              # 'email_address' is a mandatory field
        "status": "subscribed",                           # 'status' is a mandatory field
        "merge_fields": {                                 # 'merge_fields' are optional:
            "FNAME": "John",                  
            "LNAME": "Smith"
        }
    }
    new_contact_data_json = json.dumps(new_contact_data_dict)

    # Create the new contact using MailChimp API using Python 'Requests' library
    req = requests.post(
        MAILCHIMP_ADD_CONTACT_TO_LIST_URL,
        data=new_contact_data_json,
        auth=('user', MAILCHIMP_API_KEY),
        headers={"content-type": "application/json"}
    )

    # debug info if required - .text and .json also list the 'merge_fields' names for use in contact JSON above
    # print req.status_code
    # print req.text
    # print req.json()

    if req.status_code == 200:
        # success - do anything you need to do
    else:
        # fail - do anything you need to do - but here is a useful debug message
        mailchimp_fail = 'MailChimp call failed calling this URL: {0}\n' \
                         'Returned this HTTP status code: {1}\n' \
                         'Returned this response text: {2}' \
                         .format(req.url, str(req.status_code), req.text)

I faced same issue but fix it by the changing the package file section command. The whole step that i followed was:

At first try with this command: sudo apt-get install -y mongodb

This is the unofficial mongodb package provided by Ubuntu and it is not maintained by MongoDB and conflict with MongoDB’s offically supported packages.

If the above command not working then you can fix the issue by one of the bellow procedure:

#Step 1:  Import the MongoDB public key
#In Ubuntu 18.*+, you may get invalid signatures. --recv value may need to be updated to EA312927. 
#See here for more details on the invalid signature issue: [https://stackoverflow.com/questions/34733340/mongodb-gpg-invalid-signatures][1]

sudo apt-key adv --keyserver hkp://keyserver.ubuntu.com:80 --recv 7F0CEB10

#Step 2: Generate a file with the MongoDB repository url
echo 'deb http://downloads-distro.mongodb.org/repo/ubuntu-upstart dist 10gen' | sudo tee /etc/apt/sources.list.d/mongodb.list

#Step 3: Refresh the local database with the packages
sudo apt-get update

#Step 4: Install the last stable MongoDB version and all the necessary packages on our system
sudo apt-get install mongodb-org

         #Or
# The unofficial mongodb package provided by Ubuntu is not maintained by MongoDB and conflict with MongoDB’s offically supported packages. Use the official MongoDB mongodb-org packages, which are kept up-to-date with the most recent major and minor MongoDB releases.
sudo apt-get install -y mongodb 

Hope this will work for you also. You can follow this MongoDB

Update The above instruction will install mongodb 2.6 version, if you want to install latest version for Uubuntu 12.04 then just replace above step 2 and follow bellow instruction instead of that:

#Step 2: Generate a file with the MongoDB repository url
echo "deb http://repo.mongodb.org/apt/ubuntu trusty/mongodb-org/3.0 multiverse" | sudo tee /etc/apt/sources.list.d/mongodb.list

If you are using Ubuntu 14.04 then use bellow step instead of above step 2

#Step 2: Generate a file with the MongoDB repository url
echo "deb http://repo.mongodb.org/apt/ubuntu trusty/mongodb-org/3.0 multiverse" | sudo tee /etc/apt/sources.list.d/mongodb-org-3.0.list

Also to maintain accessibility, you should use this to determine your keycode:

c = e.which ? e.which : e.keyCode;

if (c == 13) ...

Assume that you have MyPayments class like

 public class Mypayment
{
    public int year { get; set; }
    public string month { get; set; }
    public string price { get; set; }
    public bool ispaid { get; set; }
}

and you have a list of MyPayments

public List<Mypayment> mypayments { get; set; }

and you want group the list by year. You can use linq like this:

List<List<Mypayment>> mypayments = (from IGrouping<int, Mypayment> item in yearGroup
                                                let mypayments1 = (from _payment in UserProjects.mypayments
                                                                   where _payment.year == item.Key
                                                                   select _payment).ToList()
                                                select mypayments1).ToList();

This is an easy way for any format. Just change it to required format string

XMLGregorianCalendar gregFmt = DatatypeFactory.newInstance().newXMLGregorianCalendar(new SimpleDateFormat("yyyy-MM-dd'T'HH:mm:ss").format(new Date()));
System.out.println(gregFmt);

I've found a solution for me with Spring and jackson

First specify the filter name in the entity

@Entity
@Table(name = "SECTEUR")
@JsonFilter(ModelJsonFilters.SECTEUR_FILTER)
public class Secteur implements Serializable {

/** Serial UID */
private static final long serialVersionUID = 5697181222899184767L;

/**
 * Unique ID
 */
@Id
@JsonView(View.SecteurWithoutChildrens.class)
@Column(name = "id")
@GeneratedValue(strategy = GenerationType.IDENTITY)
private long id;

@JsonView(View.SecteurWithoutChildrens.class)
@Column(name = "code", nullable = false, length = 35)
private String code;

/**
 * Identifiant du secteur parent
 */
@JsonView(View.SecteurWithoutChildrens.class)
@Column(name = "id_parent")
private Long idParent;

@OneToMany(fetch = FetchType.LAZY)
@JoinColumn(name = "id_parent")
private List<Secteur> secteursEnfants = new ArrayList<>(0);

}

Then you can see the constants filters names class with the default FilterProvider used in spring configuration

public class ModelJsonFilters {

public final static String SECTEUR_FILTER = "SecteurFilter";
public final static String APPLICATION_FILTER = "ApplicationFilter";
public final static String SERVICE_FILTER = "ServiceFilter";
public final static String UTILISATEUR_FILTER = "UtilisateurFilter";

public static SimpleFilterProvider getDefaultFilters() {
    SimpleBeanPropertyFilter theFilter = SimpleBeanPropertyFilter.serializeAll();
    return new SimpleFilterProvider().setDefaultFilter(theFilter);
}

}

Spring configuration :

@EnableWebMvc
@Configuration
@ComponentScan(basePackages = "fr.sodebo")

public class ApiRootConfiguration extends WebMvcConfigurerAdapter {

@Autowired
private EntityManagerFactory entityManagerFactory;


/**
 * config qui permet d'éviter les "Lazy loading Error" au moment de la
 * conversion json par jackson pour les retours des services REST<br>
 * on permet à jackson d'acceder à sessionFactory pour charger ce dont il a
 * besoin
 */
@Override
public void configureMessageConverters(List<HttpMessageConverter<?>> converters) {

    super.configureMessageConverters(converters);
    MappingJackson2HttpMessageConverter converter = new MappingJackson2HttpMessageConverter();
    ObjectMapper mapper = new ObjectMapper();

    // config d'hibernate pour la conversion json
    mapper.registerModule(getConfiguredHibernateModule());//

    // inscrit les filtres json
    subscribeFiltersInMapper(mapper);

    // config du comportement de json views
    mapper.configure(MapperFeature.DEFAULT_VIEW_INCLUSION, false);

    converter.setObjectMapper(mapper);
    converters.add(converter);
}

/**
 * config d'hibernate pour la conversion json
 * 
 * @return Hibernate5Module
 */
private Hibernate5Module getConfiguredHibernateModule() {
    SessionFactory sessionFactory = entityManagerFactory.unwrap(SessionFactory.class);
    Hibernate5Module module = new Hibernate5Module(sessionFactory);
    module.configure(Hibernate5Module.Feature.FORCE_LAZY_LOADING, true);

    return module;

}

/**
 * inscrit les filtres json
 * 
 * @param mapper
 */
private void subscribeFiltersInMapper(ObjectMapper mapper) {

    mapper.setFilterProvider(ModelJsonFilters.getDefaultFilters());

}

}

Endly I can specify a specific filter in restConstoller when i need....

@RequestMapping(value = "/{id}/droits/", method = RequestMethod.GET)
public MappingJacksonValue getListDroits(@PathVariable long id) {

    LOGGER.debug("Get all droits of user with id {}", id);

    List<Droit> droits = utilisateurService.findDroitsDeUtilisateur(id);

    MappingJacksonValue value;

    UtilisateurWithSecteurs utilisateurWithSecteurs = droitsUtilisateur.fillLists(droits).get(id);

    value = new MappingJacksonValue(utilisateurWithSecteurs);

    FilterProvider filters = ModelJsonFilters.getDefaultFilters().addFilter(ModelJsonFilters.SECTEUR_FILTER, SimpleBeanPropertyFilter.serializeAllExcept("secteursEnfants")).addFilter(ModelJsonFilters.APPLICATION_FILTER,
            SimpleBeanPropertyFilter.serializeAllExcept("services"));

    value.setFilters(filters);
    return value;

}

Change

<serviceMetadata httpsGetEnabled="true"/>

to

<serviceMetadata httpsGetEnabled="false"/>

You're telling WCF to use https for the metadata endpoint and I see that your'e exposing your service on http, and then you get the error in the title.

You also have to set <security mode="None" /> if you want to use HTTP as your URL suggests.

I had this line in my code

weakSelf?.notifications = weakSelf?.notifications ?? [] + weakSelf?.chatNotificationDataSource ?? []

this cause Segmentation fault. But then i changed it in this way:

weakSelf?.notifications = (weakSelf?.notifications ?? []) + (weakSelf?.chatNotificationDataSource ?? [])

and app started working.

I think this is what you want:

REGEX_DATE='^\d{2}[/-]\d{2}[/-]\d{4}$'

echo "$1" | grep -P -q $REGEX_DATE
echo $?

I've used the -P switch to get perl regex.

I'd just drop the database and then re-create it. On a UNIX or Linux system, that should do it:

$ dropdb development_db_name
$ createdb developmnent_db_name

That's how I do it, actually.

Shorter way using list. And you can do what you want with each date component.

list($day,$month,$year,$hour,$min,$sec) = explode("/",date('d/m/Y/h/i/s'));
echo $month.'/'.$day.'/'.$year.' '.$hour.':'.$min.':'.$sec;

#include<iostream>
#include<conio.h>
#include<string.h>
using namespace std;
int main()

{
    char str[80];

    int i;

    cout<<"\n enter string:";

    cin.getline(str,80);

    int n=strlen(str);

    cout<<"\n lenght is:"<<n;

    getch();

    return 0;

}

This is the program if you want to use strlen . Hope this helps!

You can' just add a class to each of your DIVs and apply the rule to the class in this way:

HTML:

<div class="myclass" id="s1">...</div>
<div class="myclass" id="s2">...</div>

CSS:

//css
.myclass
{
   ...
}

Proper font pre-loading is a big hole in the HTML5 spec. I've gone through all of this stuff and the most reliable solution I've found is to use Font.js:

http://pomax.nihongoresources.com/pages/Font.js/

You can use it to load fonts using the same API you use to load images

var anyFont = new Font();
anyFont.src = "fonts/fileName.otf";
anyFont.onload = function () {
  console.log("font loaded");
}

It's much simpler and more lightweight than Google's hulking Webfont Loader

Here's the github repo for Font.js:

https://github.com/Pomax/Font.js

This worked very nicely for me (only if iframe content comes from the same domain):

<script type="text/javascript">
function calcHeight(iframeElement){
    var the_height=  iframeElement.contentWindow.document.body.scrollHeight;
    iframeElement.height=  the_height;
}
</script>
<iframe src="./page.html" onLoad="calcHeight(this);" frameborder="0" scrolling="no" id="the_iframe" width="100%" ></iframe>

Use a formatter, if you only want to format it so that it renders nicely when printed. Just use the df.to_string(... formatters to define custom string-formatting, without needlessly modifying your DataFrame or wasting memory:

df = pd.DataFrame({
    'A': ['a', 'b', 'c'],
    'B': [np.nan, 1, np.nan],
    'C': ['read', 'unread', 'read']})
print df.to_string(
    formatters={'B': lambda x: '' if pd.isnull(x) else '{:.0f}'.format(x)})

To get:

   A B       C
0  a      read
1  b 1  unread
2  c      read

select price from mobile_sales_details order by price desc limit 5

Note: i have mobile_sales_details table

syntax

select column_name from table_name order by column_name desc limit size.  

if you need top low price just remove the keyword desc from order by

Try this

load data infile 'datafile location' into table schema.tablename fields terminated by ',' optionally enclosed by '|' (field1,field2,field3....)

In command prompt:

sqlldr system@databasename/password control='control file location'

Add my response with cookie :

     params.add("username", testUser);
     params.add("password", testPass);
     NullHostnameVerifier verifier = new NullHostnameVerifier(); 
     MySimpleClientHttpRequestFactory requestFactory = new MySimpleClientHttpRequestFactory(verifier , rememberMeCookie);
     ResponseEntity<String> response = restTemplate.postForEntity(appUrl + "/login", params, String.class);

     HttpHeaders headers = response.getHeaders();
     String cookieResponse = headers.getFirst("Set-Cookie");
     String[] cookieParts = cookieResponse.split(";");
     rememberMeCookie = cookieParts[0];
     cookie.setCookie(rememberMeCookie);

     requestFactory = new  MySimpleClientHttpRequestFactory(verifier,cookie.getCookie());
          restTemplate.setRequestFactory(requestFactory);
}


public class MySimpleClientHttpRequestFactory extends SimpleClientHttpRequestFactory {

        private final HostnameVerifier verifier;

        public MySimpleClientHttpRequestFactory(HostnameVerifier verifier ,String cookie) {
            this.verifier = verifier;
            this.cookie = cookie;
        }

        @Override

            return null;
        }

    }


    public class NullHostnameVerifier implements HostnameVerifier {

I encountered with this error and just decrease gradle version and android plugin version to 5.1.1 and 3.4.2.

My solution for this problem is an extension method WithIndex(),

http://code.google.com/p/ub-dotnet-utilities/source/browse/trunk/Src/Utilities/Extensions/EnumerableExtensions.cs

Use it like

var list = new List<int> { 1, 2, 3, 4, 5, 6 };    

var odd = list.WithIndex().Where(i => (i.Item & 1) == 1);
CollectionAssert.AreEqual(new[] { 0, 2, 4 }, odd.Select(i => i.Index));
CollectionAssert.AreEqual(new[] { 1, 3, 5 }, odd.Select(i => i.Item));

Here is the solution.

The HTML:

<div class="rating">
<span>?</span><span>?</span><span>?</span><span>?</span><span>?</span>
</div>

The CSS:

.rating {
  unicode-bidi: bidi-override;
  direction: rtl;
}
.rating > span {
  display: inline-block;
  position: relative;
  width: 1.1em;
}
.rating > span:hover:before,
.rating > span:hover ~ span:before {
   content: "\2605";
   position: absolute;
}

Hope this helps.

I ran into this same issue trying to install the dbf package in Python 2.7. The problem is that the enum package wasn't added to Python until version 3.4.

It has been backported to versions 3.3, 3.2, 3.1, 2.7, 2.6, 2.5, and 2.4, you just need the package from here: https://pypi.python.org/pypi/enum34#downloads

XSS will always be there even if you use $_SERVER['HTTP_HOST'], $_SERVER['SERVER_NAME'] OR $_SERVER['PHP_SELF']

You can use a simple if statement instead of continue. So instead of the way you have your code, you can try:

try(Stream<String> lines = Files.lines(path, StandardCharsets.ISO_8859_1)){
            filteredLines = lines.filter(...).foreach(line -> {
           ...
           if(!...) {
              // Code you want to run
           }
           // Once the code runs, it will continue anyway
    });
}

The predicate in the if statement will just be the opposite of the predicate in your if(pred) continue; statement, so just use ! (logical not).

Since you have not defined what an empty file is. Some might consider a file with just blank lines also an empty file. So if you want to check if your file contains only blank lines (any whitespace character, '\r', '\n', '\t'), you can follow the example below:

Python3

import re

def whitespace_only(file):
    content = open(file, 'r').read()
    if re.search(r'^\s*$', content):
        return True

Explain: the example above uses regular expression (regex) to match the content (content) of the file.
Specifically: for regex of: ^\s*$ as a whole means if the file contains only blank lines and/or blank spaces.
- ^ asserts position at start of a line
- \s matches any whitespace character (equal to [\r\n\t\f\v ])
- * Quantifier — Matches between zero and unlimited times, as many times as possible, giving back as needed (greedy)
- $ asserts position at the end of a line

change

public static final String URL = "http://api-Location";

public static final String URL = "https://api-Location"

it's happen because i'm using 000webhostapp app

Another quick lookup table is available at this github page

Note : This does not consider all the containers such as, unordered_map etc. but is still great to look at. It is just a cleaner version of this

I think the bulletproof way is:

if (typeof $.cookie('token') === 'undefined'){
 //no cookie
} else {
 //have cookie
}

Checking the type of a null, empty or undefined var always returns 'undefined'

Edit: You can get there even easier:

if (!!$.cookie('token')) {
 // have cookie
} else {
 // no cookie
}

!! will turn the falsy values to false. Bear in mind that this will turn 0 to false!

function isDate(dateStr) {
  return !isNaN(new Date(dateStr).getDate());
}

• This will work on any browser since it does not rely on "Invalid Date" check.
• This will work with legacy code before ES6.
• This will work without any library.
• This will work regardless of any date format.
• This does not rely on Date.parse which fails the purpose when values like "Spiderman 22" are in date string.
• This does not ask us to write any RegEx.

If u r using SQLite3 beware:

It takes only 't' or 'f'. Not 1 or 0. Not TRUE OR FALSE.

Just learned the hard way.

If you are using windows 7 64-bit version, then the solution is found here: http://pypi.python.org/pypi/setuptools

namely, you need to download a python script, run it, and then easy_install will work normally from commandline.

P.S. I agree with the original poster saying that this should work out of the box.

Once you set your Global Jenkins credentials, you can apply this step:

stage('Update GIT') {
  steps {
    script {
      catchError(buildResult: 'SUCCESS', stageResult: 'FAILURE') {
        withCredentials([usernamePassword(credentialsId: 'example-secure', passwordVariable: 'GIT_PASSWORD', usernameVariable: 'GIT_USERNAME')]) {
            def encodedPassword = URLEncoder.encode("$GIT_PASSWORD",'UTF-8')
            sh "git config user.email [email protected]"
            sh "git config user.name example"
            sh "git add ."
            sh "git commit -m 'Triggered Build: ${env.BUILD_NUMBER}'"
            sh "git push https://${GIT_USERNAME}:${encodedPassword}@github.com/${GIT_USERNAME}/example.git"
        }
      }
    }
  }
}

You can try ng-file-upload angularjs plugin (instead of ng-upload).

It's fairly easy to setup and deal with angularjs specifics. It also supports progress, cancel, drag and drop and is cross browser.

html

<!-- Note: MUST BE PLACED BEFORE angular.js-->
<script src="ng-file-upload-shim.min.js"></script> 
<script src="angular.min.js"></script>
<script src="ng-file-upload.min.js"></script> 

<div ng-controller="MyCtrl">
  <input type="file" ngf-select="onFileSelect($files)" multiple>
</div>

JS:

//inject angular file upload directives and service.
angular.module('myApp', ['ngFileUpload']);

var MyCtrl = [ '$scope', '$upload', function($scope, $upload) {
  $scope.onFileSelect = function($files) {
    //$files: an array of files selected, each file has name, size, and type.
    for (var i = 0; i < $files.length; i++) {
      var file = $files[i];
      $scope.upload = $upload.upload({
        url: 'server/upload/url', //upload.php script, node.js route, or servlet url
        data: {myObj: $scope.myModelObj},
        file: file,
      }).progress(function(evt) {
        console.log('percent: ' + parseInt(100.0 * evt.loaded / evt.total));
      }).then(function(response) {
        var data = response.data;
        // file is uploaded successfully
        console.log(data);
      });
    }
  };
}];

u can even try this

Function

CREATE  FUNCTION [dbo].[fn_Split](@text varchar(8000), @delimiter varchar(20))
RETURNS @Strings TABLE
(   
  position int IDENTITY PRIMARY KEY,
  value varchar(8000)  
)
AS
BEGIN

DECLARE @index int
SET @index = -1

WHILE (LEN(@text) > 0)
  BEGIN 
    SET @index = CHARINDEX(@delimiter , @text) 
    IF (@index = 0) AND (LEN(@text) > 0) 
      BEGIN  
        INSERT INTO @Strings VALUES (@text)
          BREAK 
      END 
    IF (@index > 1) 
      BEGIN  
        INSERT INTO @Strings VALUES (LEFT(@text, @index - 1))  
        SET @text = RIGHT(@text, (LEN(@text) - @index)) 
      END 
    ELSE
      SET @text = RIGHT(@text, (LEN(@text) - @index))
    END
  RETURN
END

You can get the single value for the attribute with below code:

$pa_koostis_value = get_post_meta($product->id, 'pa_koostis', true);

1. Audience. Functional testing is to assure members of the team producing the software that it does what they expect. Acceptance testing is to assure the consumer that it meets their needs.

2. Scope. Functional testing only tests the functionality of one component at a time. Acceptance testing covers any aspect of the product that matters to the consumer enough to test before accepting the software (i.e., anything worth the time or money it will take to test it to determine its acceptability).

Software can pass functional testing, integration testing, and system testing; only to fail acceptance tests when the customer discovers that the features just don't meet their needs. This would usually imply that someone screwed up on the spec. Software could also fail some functional tests, but pass acceptance testing because the customer is willing to deal with some functional bugs as long as the software does the core things they need acceptably well (beta software will often be accepted by a subset of users before it is completely functional).

Please show more of your code.

If that last piece of code declares and initializes the list variable outside the loop you're basically reusing the same list object, thus adding everything into one list.

Also show where .Capacity and .Count comes into play, how did you get those values?

There's a nodejs tool which supports json schema v4 at https://github.com/krg7880/json-schema-generator

It works either as a command line tool, or as a nodejs library:

var jsonSchemaGenerator = require('json-schema-generator'),
    obj = { some: { object: true } },
    schemaObj;

schemaObj = jsonSchemaGenerator(json);

The std::string::append() method expects its argument to be a NULL terminated string (char*).

There are several approaches for producing a string containg an int:

• std::ostringstream

  #include <sstream>
  
  std::ostringstream s;
  s << "select logged from login where id = " << ClientID;
  std::string query(s.str());
  

• std::to_string (C++11)

  std::string query("select logged from login where id = " +
                    std::to_string(ClientID));
  

• boost::lexical_cast

  #include <boost/lexical_cast.hpp>
  
  std::string query("select logged from login where id = " +
                    boost::lexical_cast<std::string>(ClientID));
  

ALTER FUNCTION [dbo].[fnTally] (@SchoolId nvarchar(50))
    RETURNS nvarchar(3)
AS BEGIN 

    DECLARE @Final nvarchar(3)
    SELECT @Final = CASE 
        WHEN yes_ans > no_ans  AND yes_ans > na_ans THEN 'Yes'
        WHEN no_ans  > yes_ans AND no_ans  > na_ans THEN 'No'
        WHEN na_ans  > yes_ans AND na_ans  > no_ans THEN 'N/A' END
    FROM dbo.qrc_maintally
    WHERE school_id = @SchoolId

Return @Final
End

As you can see, this simplifies the code a lot. It also makes other errors in your code more obvious: you're returning an nvarchar, but declared the function to return an int (corrected in the code above).

I made a fairly complicated GIS app as an experiment with it some years ago (database, complex gui, reports, client/server). It was a pleasant experience (apart from some documentation issues...) and I became productive with it very fast.

I don't use it anymore mainly because:

• it's not really general purpose
• it's not cross platform (windows only)
• I decided to stop exploring exotic technologies and specialize in something more mainstream.

No regex, so no need for //.

this should work:

$str = str_replace("\\", '/', $str);

You need to escape "\" as well.

Some simple cases can be handled by defining a default in the database schema but that doesn't handle a number of trickier cases including calculated values and keys of other models. For these cases I do this:

after_initialize :defaults

def defaults
   unless persisted?
    self.extras||={}
    self.other_stuff||="This stuff"
    self.assoc = [OtherModel.find_by_name('special')]
  end
end

I've decided to use the after_initialize but I don't want it to be applied to objects that are found only those new or created. I think it is almost shocking that an after_new callback isn't provided for this obvious use case but I've made do by confirming whether the object is already persisted indicating that it isn't new.

Having seen Brad Murray's answer this is even cleaner if the condition is moved to callback request:

after_initialize :defaults, unless: :persisted?
              # ":if => :new_record?" is equivalent in this context

def defaults
  self.extras||={}
  self.other_stuff||="This stuff"
  self.assoc = [OtherModel.find_by_name('special')]
end

There is a lot of ways to achieve this. In regards to the way you are asking, with a hidden form element.

create this form element inside your form:

<input type="hidden" name="total" value="">

So your form like this:

<form id="sampleForm" name="sampleForm" method="post" action="phpscript.php">
<input type="hidden" name="total" id="total" value="">
<a href="#" onclick="setValue();">Click to submit</a>
</form>

Then your javascript something like this:

<script>
function setValue(){
    document.sampleForm.total.value = 100;
    document.forms["sampleForm"].submit();
}
</script>

set long 9999999
set lin 400
select DBMS_METADATA.GET_DDL('USER','YOUR_USER_NAME') from dual;

This will output something like this:

SQL> select DBMS_METADATA.GET_DDL('USER','WILIAM') from dual;

DBMS_METADATA.GET_DDL('USER','WILIAM')
--------------------------------------------------------------------------------

   CREATE USER "WILIAM" IDENTIFIED BY VALUES 'S:6680C1468F5F3B36B726CE7620F
FD9657F0E0E49AE56AAACE847BA368CEB;120F24A4C2554B4F'
      DEFAULT TABLESPACE "USER"
      TEMPORARY TABLESPACE "TEMP"
      PASSWORD EXPIRE

Just use the first piece of that with alter user instead:

ALTER USER "WILIAM" IDENTIFIED BY VALUES 'S:6680C1468F5F3B36B726CE7620F
FD9657F0E0E49AE56AAACE847BA368CEB;120F24A4C2554B4F';

This will put the account back in to OPEN status without changing the password (as long as you cut and paste correctly the hash value from the output of DBMS_METADATA.GET_DDL) and you don't even need to know what the password is.

This gets part way there. There is no ActualFontSize property but there is an ActualHeight and that would relate to the FontSize. Right now this only sizes for the original render. I could not figure out how to register the Converter as resize event. Actually maybe need to register the FontSize as a resize event. Please don't mark me down for an incomplete answer. I could not put code sample in a comment.

This following code should extract face in images and save faces on disk

def detect(image):
    image_faces = []
    bitmap = cv.fromarray(image)
    faces = cv.HaarDetectObjects(bitmap, cascade, cv.CreateMemStorage(0))
    if faces:
        for (x,y,w,h),n in faces:
            image_faces.append(image[y:(y+h), x:(x+w)])
            #cv2.rectangle(image,(x,y),(x+w,y+h),(255,255,255),3)
    return image_faces

if __name__ == "__main__":
    cam = cv2.VideoCapture(0)
    while 1:
        _,frame =cam.read()
        image_faces = []
        image_faces = detect(frame)
        for i, face in enumerate(image_faces):
            cv2.imwrite("face-" + str(i) + ".jpg", face)

        #cv2.imshow("features", frame)
        if cv2.waitKey(1) == 0x1b: # ESC
            print 'ESC pressed. Exiting ...'
            break

Below is the way we are going within our developing application.

import java.text.SimpleDateFormat

String newDateAdded = "2018-11-11T09:30:31"
SimpleDateFormat dateFormat = new SimpleDateFormat("yyyy-MM-dd'T'HH:mm:ss")
Date dateAdded = dateFormat.parse(newDateAdded)

println(dateAdded)

The output looks like

Sun Nov 11 09:30:31 GMT 2018

In your example, we could adjust a bit to meet your need. If I were you, I will do:

String datePattern = "d/M/yyyy H:m:s"
String theDate = "28/09/2010 16:02:43"
SimpleDateFormat df = new SimpleDateFormat(datePattern)
println df.parse(theDate)

I hope this would help you much.

Try this-

CREATE PROCEDURE simpleproc (IN name varchar(50),IN user_name varchar(50),IN branch varchar(50))
BEGIN
    insert into student (name,user_name,branch) values (name ,user_name,branch);
END

target="_blank"

Opens a new window and show the related data.

target="_self"

Opens the window in the same frame, it means existing window itself.

target="_top"

Opens the linked document in the full body of the window.

target="_parent"

Opens data in the size of parent window.

If you need an ordered dictionary, you can use odict.

Yes. I recommend you check out Kimberly Tripp's articles on indexing.

If an index is "covering", then there is no need to use anything but the index. In SQL Server 2005, you can also add additional columns to the index that are not part of the key which can eliminate trips to the rest of the row.

Having multiple indexes, each on a single column may mean that only one index gets used at all - you will have to refer to the execution plan to see what effects different indexing schemes offer.

You can also use the tuning wizard to help determine what indexes would make a given query or workload perform the best.

As karim79 mentioned, the first is the most concise. However I could argue that the second is more understandable as it is not obvious/known to some Javascript/jQuery programmers that non-zero/false values are evaluated to true in if-statements. And because of that, the third method is incorrect.

Swift

This gets a view controller from the storyboard and presents it.

let storyboard = UIStoryboard(name: "Main", bundle: nil)
let secondViewController = storyboard.instantiateViewController(withIdentifier: "secondViewControllerId") as! SecondViewController
self.present(secondViewController, animated: true, completion: nil)

Change the storyboard name, view controller name, and view controller id as appropriate.

No, but you can do this almost as easily.

Build your icons using that page, and then download the zip package. Unzip it into the right directory and it'll overwrite all the drawable-*/ic_launcher.png correctly.

It works with Android Studio 1.2 + OpenCV-2.4.11-android-sdk (.zip), too.

Just do the following:

1) Follow the answer that starts with "You can do this very easily in Android Studio. Follow the steps below to add OpenCV in your project as library." by TGMCians.

2) Modify in the <yourAppDir>\libraries\opencv folder your newly created build.gradle to (step 4 in TGMCians' answer, adapted to OpenCV2.4.11-android-sdk and using gradle 1.1.0):

apply plugin: 'android-library'

buildscript {
    repositories {
        mavenCentral()
    }
    dependencies {
        classpath 'com.android.tools.build:gradle:1.1.0'
    }
}

android {
    compileSdkVersion 21
    buildToolsVersion "21.1.2"

    defaultConfig {
        minSdkVersion 8
        targetSdkVersion 21
        versionCode 2411
        versionName "2.4.11"
    }

    sourceSets {
        main {
            manifest.srcFile 'AndroidManifest.xml'
            java.srcDirs = ['src']
            resources.srcDirs = ['src']
            res.srcDirs = ['res']
            aidl.srcDirs = ['src']
        }
    }
}

3) *.so files that are located in the directories "armeabi", "armeabi-v7a", "mips", "x86" can be found under (default OpenCV-location): ..\OpenCV-2.4.11-android-sdk\OpenCV-android-sdk\sdk\native\libs (step 9 in TGMCians' answer).

Enjoy and if this helped, please give a positive reputation. I need 50 to answer directly to answers (19 left) :)

Please refer to the following method. It takes your date String as argument1, you need to specify the existing format of the date as argument2, and the result (expected) format as argument 3.

Refer to this link to understand various formats: Available Date Formats

public static String formatDateFromOnetoAnother(String date,String givenformat,String resultformat) {

    String result = "";
    SimpleDateFormat sdf;
    SimpleDateFormat sdf1;

    try {
        sdf = new SimpleDateFormat(givenformat);
        sdf1 = new SimpleDateFormat(resultformat);
        result = sdf1.format(sdf.parse(date));
    }
    catch(Exception e) {
        e.printStackTrace();
        return "";
    }
    finally {
        sdf=null;
        sdf1=null;
    }
    return result;
}

Create a "module" object and declare variables in there. Unlike class-objects that have to be instantiated each time, the module objects are always available. Therefore, a public variable, function, or property in a "module" will be available to all the other objects in the VBA project, macro, Excel formula, or even within a MS Access JET-SQL query def.

I slightly disagree with the above. The unsigned char simply means: Use the most significant bit instead of treating it as a bit flag for +/- sign when performing arithmetic operations.

It makes significance if you use char as a number for instance:

typedef char BYTE1;
typedef unsigned char BYTE2;

BYTE1 a;
BYTE2 b;

For variable a, only 7 bits are available and its range is (-127 to 127) = (+/-)2^7 -1. For variable b all 8 bits are available and the range is 0 to 255 (2^8 -1).

If you use char as character, "unsigned" is completely ignored by the compiler just as comments are removed from your program.

Here is a simple linear time solution to this simple linear time problem.

When I run this snippet, with n = 1 million, each call to filterInPlace() takes .013 to .016 seconds. A quadratic solution (e.g. the accepted answer) would take a million times that, or so.

// Remove from array every item such that !condition(item).
function filterInPlace(array, condition) {
   var iOut = 0;
   for (var i = 0; i < array.length; i++)
     if (condition(array[i]))
       array[iOut++] = array[i];
   array.length = iOut;
}

// Try it out.  A quadratic solution would take a very long time.
var n = 1*1000*1000;
console.log("constructing array...");
var Auction = {auctions: []};
for (var i = 0; i < n; ++i) {
  Auction.auctions.push({seconds:1});
  Auction.auctions.push({seconds:2});
  Auction.auctions.push({seconds:0});
}
console.log("array length should be "+(3*n)+": ", Auction.auctions.length)
filterInPlace(Auction.auctions, function(auction) {return --auction.seconds >= 0; })
console.log("array length should be "+(2*n)+": ", Auction.auctions.length)
filterInPlace(Auction.auctions, function(auction) {return --auction.seconds >= 0; })
console.log("array length should be "+n+": ", Auction.auctions.length)
filterInPlace(Auction.auctions, function(auction) {return --auction.seconds >= 0; })
console.log("array length should be 0: ", Auction.auctions.length)

Note that this modifies the original array in place rather than creating a new array; doing it in place like this can be advantageous, e.g. in the case that the array is the program's single memory bottleneck; in that case, you don't want to create another array of the same size, even temporarily.

I agree with erickson's answer, with one caveat: for password authentication purposes, bcrypt is far better than a single iteration of SHA-512 - simply because it is far slower. If you don't get why slowness is an advantage in this particular game, read the article you linked to again (scroll down to "Speed is exactly what you don’t want in a password hash function.").

You can of course build a secure password hashing algorithm around SHA-512 by iterating it thousands of times, just like the way PHK's MD5 algorithm works. Ulrich Drepper did exactly this, for glibc's crypt(). There's no particular reason to do this, though, if you already have a tested bcrypt implementation available.

I had this same problem and it had nothing to do with tabs. This was my problem code:

def genericFunction(variable):

    for line in variable:

       line = variable


   if variable != None:
      return variable

Note the above for is indented with more spaces than the line that starts with if. This is bad. All your indents must be consistent. So I guess you could say I had a stray space and not a stray tab.

I was facing the same problem and non of the above solutions helped me. In my Web Api 2 project, I had actually updated my database and had placed a unique constraint on an SQL table column. That was actually causing the problem. Simply Checking the the duplicate column values before inserting helped me fix the problem!

The best practice to download an image from Server or from Website and store it locally.

client.Dispose();

Rob W answer helped me figure out how to pause a video over iframe when a slider is hidden. Yet, I needed some modifications before I could get it to work. Here is snippet of my html:

<div class="flexslider" style="height: 330px;">
  <ul class="slides">
    <li class="post-64"><img src="http://localhost/.../Banner_image.jpg"></li>
    <li class="post-65><img  src="http://localhost/..../banner_image_2.jpg "></li>
    <li class="post-67 ">
        <div class="fluid-width-video-wrapper ">
            <iframe frameborder="0 " allowfullscreen=" " src="//www.youtube.com/embed/video-ID?enablejsapi=1 " id="fitvid831673 "></iframe>
        </div>
    </li>
  </ul>
</div>

Observe that this works on localhosts and also as Rob W mentioned "enablejsapi=1" was added to the end of the video URL.

Following is my JS file:

jQuery(document).ready(function($){
    jQuery(".flexslider").click(function (e) {
        setTimeout(checkiframe, 1000); //Checking the DOM if iframe is hidden. Timer is used to wait for 1 second before checking the DOM if its updated

    });
});

function checkiframe(){
    var iframe_flag =jQuery("iframe").is(":visible"); //Flagging if iFrame is Visible
    console.log(iframe_flag);
    var tooglePlay=0;
    if (iframe_flag) {                                //If Visible then AutoPlaying the Video
        tooglePlay=1;
        setTimeout(toogleVideo, 1000);                //Also using timeout here
    }
    if (!iframe_flag) {     
        tooglePlay =0;
        setTimeout(toogleVideo('hide'), 1000);  
    }   
}

function toogleVideo(state) {
    var div = document.getElementsByTagName("iframe")[0].contentWindow;
    func = state == 'hide' ? 'pauseVideo' : 'playVideo';
    div.postMessage('{"event":"command","func":"' + func + '","args":""}', '*');
};

use Javascript sort() function

var $tbody = $('table tbody');
$tbody.find('tr').sort(function(a,b){ 
    var tda = $(a).find('td:eq(1)').text(); // can replace 1 with the column you want to sort on
    var tdb = $(b).find('td:eq(1)').text(); // this will sort on the second column
            // if a < b return 1
    return tda < tdb ? 1 
           // else if a > b return -1
           : tda > tdb ? -1 
           // else they are equal - return 0    
           : 0;           
}).appendTo($tbody);

If you want ascending you just have to reverse the > and <

Change the logic accordingly for you.

You can use duplicated to do this very quickly.

test[!duplicated(test$id),]

Benchmarks, for the speed freaks:

ju <- function() test[!duplicated(test$id),]
gs1 <- function() do.call(rbind, lapply(split(test, test$id), head, 1))
gs2 <- function() do.call(rbind, lapply(split(test, test$id), `[`, 1, ))
jply <- function() ddply(test,.(id),function(x) head(x,1))
jdt <- function() {
  testd <- as.data.table(test)
  setkey(testd,id)
  # Initial solution (slow)
  # testd[,lapply(.SD,function(x) head(x,1)),by = key(testd)]
  # Faster options :
  testd[!duplicated(id)]               # (1)
  # testd[, .SD[1L], by=key(testd)]    # (2)
  # testd[J(unique(id)),mult="first"]  # (3)
  # testd[ testd[,.I[1L],by=id] ]      # (4) needs v1.8.3. Allows 2nd, 3rd etc
}

library(plyr)
library(data.table)
library(rbenchmark)

# sample data
set.seed(21)
test <- data.frame(id=sample(1e3, 1e5, TRUE), string=sample(LETTERS, 1e5, TRUE))
test <- test[order(test$id), ]

benchmark(ju(), gs1(), gs2(), jply(), jdt(),
    replications=5, order="relative")[,1:6]
#     test replications elapsed relative user.self sys.self
# 1   ju()            5    0.03    1.000      0.03     0.00
# 5  jdt()            5    0.03    1.000      0.03     0.00
# 3  gs2()            5    3.49  116.333      2.87     0.58
# 2  gs1()            5    3.58  119.333      3.00     0.58

Let's try that again, but with just the contenders from the first heat and with more data and more replications.

set.seed(21)
test <- data.frame(id=sample(1e4, 1e6, TRUE), string=sample(LETTERS, 1e6, TRUE))
test <- test[order(test$id), ]
benchmark(ju(), jdt(), order="relative")[,1:6]
#    test replications elapsed relative user.self sys.self
# 1  ju()          100    5.48    1.000      4.44     1.00
# 2 jdt()          100    6.92    1.263      5.70     1.15

Your command is completely incorrect. The output format is not rawvideo and you don't need the bitstream filter h264_mp4toannexb which is used when you want to convert the h264 contained in an mp4 to the Annex B format used by MPEG-TS for example. What you want to use instead is the aac_adtstoasc for the AAC streams.

ffmpeg -i http://.../playlist.m3u8 -c copy -bsf:a aac_adtstoasc output.mp4

ngIf makes a manipulation on the DOM by removing or recreating the element.

Whereas ngShow applies a css rules to hide/show things.

For most of the cases (not always), I would summarize this as, if you need a one time check to show/hide things, use ng-if, if you need to show/hide things based on the user actions on the screen (like checked a checkbox then show textbox, unchecked then hide textbox etc..), then use ng-show

Instead of doing all these greps and stuff, I'd advise you to use ps capabilities of changing output format.

ps -o cmd= -p 12345

You get the cmmand line of a process with the pid specified and nothing else.

This is POSIX-conformant and may be thus considered portable.

I have done following code to get the IP of MAC known device. This can be modified accordingly to obtain all IPs with some string manipulation. Hope this will help you.

#running windows cmd line  statement and put output into a string
cmd_out = os.popen("arp -a").read()
line_arr = cmd_out.split('\n')
line_count = len(line_arr)


#search in all lines for ip
for i in range(0, line_count):
    y = line_arr[i]
    z = y.find(mac_address)

    #if mac address is found then get the ip using regex matching
    if z > 0:
        ip_out= re.search('[0-9]+\.[0-9]+\.[0-9]+\.[0-9]+', y, re.M | re.I)

Could you use jQuery, since it's cross-browser compatible?

function isOnScreen(element)
{
    var curPos = element.offset();
    var curTop = curPos.top;
    var screenHeight = $(window).height();
    return (curTop > screenHeight) ? false : true;
}

And then call the function using something like:

if(isOnScreen($('#myDivId'))) { /* Code here... */ };

Well I guess you can use checked="false". That is the html way to leave a checkbox unchecked. You can refer to http://www.w3schools.com/jsref/dom_obj_checkbox.asp.

Had the same problem and none of the above solutions worked. So, by reading carefully the logs, I found this message :

10:55:42 [Apache] Port 443 in use by ""C:\Program Files (x86)\VMware\VMware Workstation\vmware-hostd.exe" -u "C:\ProgramData\VMware\hostd\config.xml"" with PID 1908!

In my case, I had just to stop the VMWare service which was running automatically.

The key is to read carefully the message given by XAMPP Panel when started.

Hope this help!

I have also been through this problem,

First i tried setting my password of root to blank using command :

SET PASSWORD FOR root@localhost=PASSWORD('');

But don't be happy , PHPMYADMIN uses 127.0.0.1 not localhost , i know you would say both are same but that is not the case , use the command mentioned underneath and you are done.

SET PASSWORD FOR [email protected]=PASSWORD('');

Just replace localhost with 127.0.0.1 and you are done .

Please take a look here

HH is hour in a day (starting from 0 to 23)

hh are hours in am/pm format

kk is hour in day (starting from 1 to 24)

mm is minute in hour

ss are the seconds in a minute

The mod_authz_host directives need to be inside a <Location> or <Directory> block but I've used the former within <VirtualHost> like so for Apache 2.2:

<VirtualHost *:8080>
    <Location />
    Order deny,allow
    Deny from all
    Allow from 127.0.0.1
    </Location>

    ...
</VirtualHost>

I have come across this error when the app resides on a network share, and the device (laptop, tablet, ...) becomes disconnected from the network while the app is in use. In my case, it was due to a Surface tablet going out of wireless range. No problems after installing a better WAP.

I stumbled on this question while trying to do the same thing (I think). Here is how I did it:

df['index_col'] = df.index

You can then sort on the new index column, if you like.

At the end I use a little JavaScript to achieve it:

if (navigator.vendor.startsWith('Apple'))
    document.documentElement.classList.add('on-apple');

then in my CSS to target Apple browser engine the selector will be:

.on-apple .my-class{
    ...
}

My simple solution is:

nextday=new Date(oldDate.getFullYear(),oldDate.getMonth(),oldDate.getDate()+1);

this solution does not have problem with daylight saving time. Also, one can add/sub any offset for years, months, days etc.

day=new Date(oldDate.getFullYear()-2,oldDate.getMonth()+22,oldDate.getDate()+61);

is correct code.

Like others mentioned in this thread, replacing the entire body HTML is a bad idea because it reinserts the entire DOM and can potentially break any other javascript that was acting on those elements.

Instead, replace just the text on your page and not the DOM elements themselves using jQuery filter:

  $('body :not(script)').contents().filter(function() {
    return this.nodeType === 3;
  }).replaceWith(function() {
      return this.nodeValue.replace('-9o0-9909','The new string');
  });

this.nodeType is the type of node we are looking to replace the contents of. nodeType 3 is text. See the full list here.

I'm using Version 4.0.2.15 with Build 15.21

For me I needed this:

UPDATE table_name SET column_name = REPLACE(column_name,"search str","replace str");

Putting t.column_name in the first argument of replace did not work.

Well, generally MVC is used in Web development and MVVM is most popular in WPF/Silverlight development. However, sometimes the web architecute might have a mix of MVC and MVVM.

For example: you might use knockout.js and in this case you will have MVVM on your client side. And your MVC's server side can also change. In the complex apps, nobody uses the pure Model. It might have a sense to use a ViewModel as a "Model" of MVC and your real Model basically will be a part of this VM. This gives you an extra abstraction layer.

I take it that is a Vista Window! I often got this when first trying to port a DirectX program from XPsp3 to Vista.

It's a .dll problem. The OpenCV runtime.dll will call upon a system.dll that will be no longer shipped Vista, so unfortunately you will have to to a bit of hunting to find which system.dll it's trying to find. (system.dll could be vc2010 or vista)

This error is also caused by incorrect installation of .dlls (i.e not rolling out) hth Happy hunting

You can get the values with use of ID. But ID should be Unique.

<body>
<h1>Adding 'a' and 'b'</h1>
<form>
  a: <input type="number" name="a" id="a"><br>
  b: <input type="number" name="b" id="b"><br>
  <button onclick="add()">Add</button>
</form>
<script>
  function add() {
    a = $('#a').val();
    b = $('#b').val();
    var sum = a + b;
    alert(sum);
  }
</script>
</body>

Some receivers expect EOL sequence, which is typically two characters \r\n, so try in your code replace the line

unsigned char cmd[] = {'I', 'N', 'I', 'T', ' ', '\r', '\0'};

with

unsigned char cmd[] = "INIT\r\n";

BTW, the above way is probably more efficient. There is no need to quote every character.

nohup node server.js > /dev/null 2>&1 &

1. nohup means: Do not terminate this process even when the stty is cut off.
2. > /dev/null means: stdout goes to /dev/null (which is a dummy device that does not record any output).
3. 2>&1 means: stderr also goes to the stdout (which is already redirected to /dev/null). You may replace &1 with a file path to keep a log of errors, e.g.: 2>/tmp/myLog
4. & at the end means: run this command as a background task.

The simplest thing you can do is cherry picking a range. It does the same as the rebase --onto but is easier for the eyes :)

alert() doesn't support HTML, but you have some alternatives to format your message.

You can use Unicode characters as others stated, or you can make use of the ES6 Template literals. For example:

...
.catch(function (error) {
  const alertMessage = `Error retrieving resource. Please make sure:
    • the resource server is accessible
    • you're logged in

    Error: ${error}`;
  window.alert(alertMessage);
}

Output:

As you can see, it maintains the line breaks and spaces that we included in the variable, with no extra characters.

A quick search on the conda official docs will help you to find what each flag does.

So far:

• -y: Do not ask for confirmation.
• -f: I think it should be --file, so it read package versions from the given file.
• -q: Do not display progress bar.
• -c: Additional channel to search for packages. These are URLs searched in the order

i have an jquery plugin for this. It uses jquery-ui also. You can see an example here http://jsfiddle.net/tugrulorhan/fd8KB/1/

$("#searchContainer").gridSearch({
            primaryAction: "search",
            scrollDuration: 0,
            searchBarAtBottom: false,
            customScrollHeight: -35,
            visible: {
                before: true,
                next: true,
                filter: true,
                unfilter: true
            },
            textVisible: {
                before: true,
                next: true,
                filter: true,
                unfilter: true
            },
            minCount: 2
        });

If you need to respond to changes, you can try this:

document.getElementById('select-meal-type').addEventListener('change', function(e) {
    let values = [].slice.call(e.target.selectedOptions).map(a => a.value));
})

The [].slice.call(e.target.selectedOptions) is needed because e.target.selectedOptions returns a HTMLCollection, not an Array. That call converts it to Array so that we can then apply the map function, which extract the values.
